BACKGROUND OF THE INVENTION FIELD OF REVELATION

[0002] The present disclosure relates, for example, to wireless communication systems, and more particularly to the implementation of access class blocking for device-to-device proximity service communications.

DESCRIPTION OF THE RELATED TECHNIQUE

[0003] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting and so on. These systems may be multiple access systems capable of supporting communication with multiple users by sharing available system resources (eg time, frequency and power). Examples of such multiple access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, and frequency division multiple access systems. frequency orthogonal (OFDMA).

[0004] By way of example, a wireless multiple access communication system may include multiple base stations, each of which simultaneously supports communication to multiple communication devices, otherwise known as user equipment (UEs). A base station can communicate with UEs on downlink channels (for example, for transmissions from a base station to a UE) and uplink channels (for example, for transmissions from a UE to a base station). UEs can be assigned an access class parameter associated with blocking protocols that control access to the base station in certain emergency scenarios, for example. Normal (or non-high priority) UEs can be assigned an access class 0 to 9. High priority UEs can be assigned an access class 11 to 15. Other access classes can be assigned on a service basis (e.g. (e.g., audio/video phone services, messaging services, etc.). When class of access blocking is active, the blocking condition and assigned class of access parameter can determine whether resources are available for a particular UE or service.

[0005] Device-to-Device (D2D) communications involve direct wireless communications between UEs. D2D communications can provide proximity service functions to be performed between UEs within the same geographic area. Exemplary proximity service functions might include advertisements within a defined geographic area, sales information within a shopping centre, etc. UEs can communicate via D2D proximity service communications by accessing resources associated with direct discovery, direct communications, etc. Current access class blocking procedures may not consider D2D proximity service communications, and therefore UEs may experience difficulty, or be prevented from, accessing resources for D2D proximity service communications when the class of access blocking access is active.

SUMMARY

[0006] The features described generally refer to one or more improved systems, methods and/or apparatus for Access Class Blocking (ACB) procedures for D2D Proximity Service communications.

Access classes can include ACB parameters associated with, for example, direct discovery to normal priority UEs, direct discovery to high priority UEs, direct communication to normal priority UEs, and/or direct communications to high priority UEs. ACB parameters can be assigned and provided to UEs from a serving cell in a message, for example a type 2 SIB. UEs can identify available resources based on the assigned ACB parameter, for example depending on whether the lockout is active or not and, when active, the lockout condition and assigned ACB parameter. When resources are available, for example discovery or communication resources, UEs can request the resource by sending a radio resource control (RRC) connection request message that has an establishment cause associated with the ACB parameter assigned.

DETAILED DESCRIPTION

[0048] Currently, a UE wishing to participate in D2D proximity service communications may be denied access to resources based on a blocking condition that may not consider the nature of the desired resource, for example, for proximity service communications D2D Proximity. Existing protocols can also provide inconsistent resource allocations when access blocking is active. For example, a UE performing discovery and/or communication operations using resources assigned by a serving base station may be blocked from accessing the resources when access blocking is active. A UE performing discovery and/or communication operations may, however, access a non-UE specific grouping of specific resources based on information carried in a system information block (SIB) while the access block is active. Consequently, current blocking procedures do not consider D2D Proximity Service communications and may, in certain situations, result in inconsistent results for UEs accessing resources for D2D Proximity Service communications.

[0049] In accordance with aspects of the present description, ACB parameters are defined and provided to UEs for D2D proximity service communications. ACB parameters can be defined for discovery capabilities for normal and high priority UEs, for communication capabilities for normal and high priority UEs, etc. ACB parameters may be communicated to the UE by a serving base station, for example. The UE can identify resource availability based on assigned ACB parameters. For example, when access class blocking is active, the UE can identify the availability of a resource based on the assigned ACB parameters and the blocking condition, for example, an emergency situation. UEs can request a resource identified as available by sending an RRC connection request (or establishment message) to the serving base station. The RRC connection request message may include an establishment cause that matches the assigned ACB parameters, for example, discovery operations for normal and high priority UEs and communication operations for normal and high priority UEs . Consequently, the serving base station can allocate resources during class-of-access blocking situations for D2D Proximity Service communications.

[0050] The following description provides examples and is not limited to the scope, applicability or examples presented in the claims. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of the disclosure. Multiple examples can omit, replace, or add multiple procedures or components as appropriate. For example, the methods described can be performed in a different order than described, and multiple steps can be added, omitted, or combined. Furthermore, the features described in relation to some examples can be combined in other examples.

[0051] Figure 1 illustrates an example of a wireless communication system 100 in accordance with various aspects of the disclosure. The wireless communications system 100 includes base stations 105, UEs 115, and a core network 130. The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access functions. , routing, or mobility. Base stations 105 interface with core network 130 via backhaul links 132 (e.g., SI, etc.) and may provide radio configuration and scheduling for communication with UEs 115, or may operate under the control of a base station controller (not shown). In various examples, base stations 105 may communicate, directly or indirectly (e.g., through the core network 130), with each other over backhaul links 134 (e.g., XI, etc.), which may be wireless or wired communication.

[0052] The base stations 105 can communicate wirelessly with the UEs 115 via one or more base station antennas. Each of the base station locations 105 may provide communication coverage for a respective geographic coverage area 110. In some examples, the base stations 105 may be called a base transceiver station, a radio base station, a access point, a radio transceiver, a NodeB, eNodeB (eNB), Home NodeB, a Home eNodeB, or some other suitable terminology. The geographic coverage area 110 for a base station can be divided into sectors that form only a portion of the coverage area (not shown). The wireless communication system 100 may include base stations 105 of different types (e.g., macrocell and/or small cell base stations). There may be overlapping geographic coverage areas 110 for different technologies.

[0053] In some examples, the wireless communication system 100 is an LTE/LTE-A network. In LTE/LTE-A networks, the term Evolved Node B (eNB) can generally be used to describe the base stations 105, while the term UE can generally be used to describe the UEs 115. Wireless communications 100 can be a Heterogeneous LTE/LTE-A network in which different types of eNBs provide coverage for various geographic regions. For example, each eNB or base station 105 can provide communication coverage for a macro cell, a small cell, and/or other cell types. The term "cell" is a 3GPP term that can be used to describe a base station, a carrier or component carrier associated with a base station, or a coverage area (e.g. sector, etc.) of a carrier or base station, depending on the context.

[0054] A macrocell generally covers a relatively large geographic area (for example, several kilometers in radius) and can allow unrestricted access by UEs with service subscriptions with the network provider. The small cell is a lower power base station compared to a macro cell, which can operate in the same or different frequency bands (eg licensed, unlicensed, etc.) as the macro cells. Small cells can include picocells, femtocells and microcells according to various examples. A picocell can cover a relatively smaller geographic area and can allow unrestricted access by UEs with service subscriptions with the network provider. A femtocell could also cover a relatively smaller geographic area (e.g. a household) and, in addition to unrestricted access, could also provide restricted access by UEs that have an association to a femtocell (e.g., the UEs in a closed subscriber group (CSG), UEs for in-home users, and the like). An eNB for a macrocell can be called an eNB macro. An eNB for a small cell may be called a small cell eNB, a pico eNB, a femto eNB, or a household eNB. An eNB can support one or multiple (eg two, three, four and the like) cells (eg component carriers).

[0055] The wireless communication system 100 can support either synchronous or asynchronous operation. For synchronous operation, base stations can have similar frame timing, and transmissions from different base stations can be approximately aligned in time. For asynchronous operation, base stations may have different frame timing, and transmissions from different base stations may not be time-aligned. The sets of procedures in this document can be used for both synchronous and asynchronous operations.

[0056] The communication networks that can accommodate some of the various examples disclosed may be packet-based networks that operate according to a layered protocol stack. At the user plane, communications at the Packet Data Convergence Protocol (PDCP) layer or on the bearer can be IP-based. A Radio Link Control (RLC) layer can perform packet reassembly and segmentation to communicate over logical channels. A Media Access Control (MAC) layer can perform multiplexing and priority handling of logical channels on transport channels. The MAC layer can also use Hybrid ARQ (HARQ) to provide retransmission at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide for establishing, configuring, and maintaining an RRC connection between a UE 115 and base stations 105 or core network 130 supporting bearers. radio to user plan data. At the Physical (PHY) layer, transport channels can be mapped to Physical channels.

[0057] The UEs 115 are dispersed throughout the wireless communication system 100 and each UE 115 can be stationary or mobile. A UE 115 may also be referred to by those skilled in the art as a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other proper terminology. A UE 115 can be a cell phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet-type computer, a laptop-type computer, a cordless telephone , a Wireless Local Loop Station (WLL) or similar. A UE 115 may have the capability to communicate with various types of base stations and network equipment including macro eNBs, small cell eNBs, relay base stations and the like. other UEs within or outside the same coverage area of a base station via D2D communications, for example for proximity service communication functions. A UE 115 may be able to communicate with other UEs over a PC5 air interface (reference point of PC5 as described in the 3rd Generation Partnership Project, Technical Specification 23.303, for example) which carries application codes of proximity service for encapsulated Internet Protocol (IP) packets of proximity service and direction discovery for direct communications. Similarly, a UE 115 may have the ability to communicate with a proximity service function via a PC3 reference point protocol over IP to distribute an authorization policy for direct discovery and perform code allocation/resolution. corresponding to the proximity service application identities used for direct discovery.

[0058] The communication links 125 shown in the wireless communication system 100 may include uplink (UL) transmissions from a UE 115 to a base station 105, and/or downlink (DL) transmissions, to from a base station 105 to a UE 115. Downlink transmissions can also be called forward link transmissions while uplink transmissions can also be called reverse link transmissions. Each communication link 125 may include one or more carriers, where each carrier may be a composite signal of multiple subcarriers (e.g., waveform signals of different frequencies) modulated in accordance with the various radio technologies described above. Each modulated signal can be sent on a different subcarrier and can carry control information (for example, reference signals, control channels, etc.), supplementary information, user data, etc. Communication links 125 can carry bi-directional communications using FDD (eg, using paired spectrum resources) or TDD operation (eg, using unpaired spectrum resources). Frame structures for FDD (eg type 1 frame structure) and TDD (eg type 2 frame structure) can be defined.

[0059] In some embodiments of the system 100, base stations 105 and/or UEs 115 may include multiple antennas to employ antenna diversity schemes to improve reliability and quality of communication between base stations 105 and UEs 115. Additionally or alternatively , base stations 105 and/or UEs 115 may employ sets of multiple-input, multiple-output (MIMO) procedures that can take advantage of multipath environments to transmit multiple spatial layers that carry the same encoded data or different encoded data.

[0060] The wireless communication system 100 can support block access class operations for D2D proximity service communications. A base station 105 can, alone or in cooperation with one or more other network entities, determine and transport an ACB parameter to UEs 115 within its coverage area. The ACB parameter may correspond to normal priority/high priority UEs for discovery/communication operations associated with D2D proximity service communications. The ACB parameter can be carried to the UEs in a type 2 SIB, for example. UEs can identify whether a resource is available based on the assigned ACB parameter. For example, when access class blocking is active, the UE can identify the resource based on the blocking condition/restrictions and its assigned ACB parameter. If blocking constraints prohibit resource allocation for the assigned ACB parameter, the UE may determine that no resource is available. If resource allocation is not blocked, the UE can determine that a resource is available and can then send a request to its serving base station 105 requesting the resource. The request may be an RRC connection request message that includes a defined establishment cause based on D2D proximity service communications, for example, corresponding to the assigned ACB parameter.

[0061] Figure 2 shows a block diagram 200 of a device 115-a for use in wireless communication, in accordance with various aspects of the present disclosure; Device 115-d may be an example of one or more aspects of a UE 115 described with reference to Figure 1. Device 115-a may include a receiver module 205, an Access Class Blocking (ACB) module 210, and and/or a transmitter module 215. Device 115-a may also be or include a processor (not shown). Each of these modules can be in communication with each other.

[0062] The components of device 115-a may, individually or collectively, be implanted using one or more application-specific integrated circuits (ASICs) adapted to perform some or all of the applicable functions in hardware. Alternatively, functions may be performed by one or more processing units (or cores) on one or more integrated circuits. In other examples, other types of integrated circuits may be used (for example, Structured/platform ASICs, Field Programmable Gate Arrays (FPGAs), and other semi-custom ICs), which may be programmed in any manner known in the art. The functions of each module can also be implemented, totally or partially, with instructions incorporated in a memory, formatted to be executed by one or more general or specific application processors.

[0063] The receiver module 205 can receive information such as packets, user data and/or control information associated with various information channels (eg, control channels, data channels, etc.). Receiver module 205 may receive messages from a serving base station that include information associated with access class blocking operations for D2D proximity service communications. Receiver module 205 may also receive signals from a different UE, via D2D communications, which include information or are otherwise associated with proximity service communications, e.g. discovery signals, communications, etc. Information may be passed to the ACB module 210, and to other components of device 115-a.

[0064] The ACB module 210 can manage access class blocking operations for device 115-a. ACB module 210 may receive a message, via receiver module 205, from a serving cell that includes an ACB parameter assigned to device 115-a. The ACB module 210 may identify or otherwise determine if a facility is available for D2D proximity service communications based on the assigned ACB parameter. For example, ACB module 210 can determine whether access class blocking is on or off and, when enabled, whether the blocking condition and assigned ACB parameter would provide resource availability for D2D Proximity Service communications. When resources for D2D proximity service communication are identified as available, the ACB module 210 may send, via transmitter module 215, a message to the serving cell requesting the available resource.

[0065] The transmitter module 215 can transmit the one or more signals received from other components of the device 115-a. Transmitter module 215 can transmit information such as packets, user data and/or control information to a serving cell. Transmitter module 215 may send messages to the serving cell in combination with access class blocking operations. Transmitter module 215 may also send signals to a different UE via D2D communications for proximity service communications. In some examples, transmitter module 215 may be collocated with receiver module 205 in a transceiver module.

[0066] Figure 3 shows a block diagram 300 of a device 115-b for use in wireless communication, according to various examples. Device 115-b may be an example of one or more aspects of a UE 115 described with reference to Figure 1. It may also be an example of a device 115-a described with reference to Figure 2. Device 115-b it may include a receiver module 205-a, an ACB module 210-a and/or a transmitter module 215-a, which may be examples of corresponding modules of the device 115-a. Device 115-b-a may also include a processor (not shown). Each of these components can be in communication with each other. The ACB module 210-a may include an ACB management module 305, a proximity service management module 310, a resource management module 315, and an RRC connection management module 320. The receiver module 205- a and transmitter module 215-a can perform the functions of receiver module 205 and transmitter module 215 of Figure 2, respectively.

[0067] The components of the 115-b device can, individually or collectively, be implanted using one or more application-specific integrated circuits (ASICs) adapted to perform some or all of the applicable functions in hardware. Alternatively, functions may be performed by one or more processing units (or cores) on one or more integrated circuits. In other examples, other types of integrated circuits may be used (eg, structured/platform ASICs, Field Programmable Gate Arrays (FPGAs, and other semi-custom ICs), which may be programmed in any manner known in the art. each module can also be implemented, in whole or in part, with instructions embedded in a memory, formatted to be executed by one or more processors of general or specific application.

[0068] The ACB management module 305 can manage aspects of access class blocking operations for device 115-b. The ACB management module 305 can receive an ACB parameter from a serving cell. The ACB parameter may assign device 115-b, with respect to access class blocking operations, as one or more than one normal priority UE for discovery operations or communication operations, or the ACB parameter may assign the device 115-b as a high priority UE for discovery operations and communication operations. The ACB management module 305 may, for example, process a system information block (SIB) received from the serving cell to determine the assigned ACB parameter. The ACB 305 management module can also determine whether access class blocking operations are active or inactive. When active, the ACB 305 management module can determine the blocking condition associated with active blocking operations, for example, the emergency condition. The ACB management module 305 can therefore determine or otherwise control a state transition for the device 115-b from an unblocked state to a blocked state. The ACB 305 management module can issue information to the ACB 210-a module components indicating the blocked/non-blocked state, assigned ACB parameter and blocking condition, when applicable.

[0069] Proximity service management module 310 may manage proximity service operations for device 115-b. For example, proximity service management module 310 may include, or communicate with, one or more proximity service protocols from device 115-b. The proximity service management module 310 can, in cooperation with the proximity service protocol (or protocols), issue proximity service application codes (periodically and without D2D signaling) to direct discovery services for service communications D2D Proximity. Additionally, proximity service management module 310 may, in cooperation with one or more other device components 115-b, output encapsulated IP packets for direct communication to D2D proximity service communications.

[0070] The proximity service management module 310 can, in cooperation with the receiver module 205-a and/or the transmitter module 215-a, receive and/or send one or more discovery request signals (announce) for communications of proximity service of D2D. When sending the announcement signal, the proximity service management module 310 can coordinate with the ACB management module 305, the resource management module 315 and/or the RRC connection management module 320 to use a resource identified and associated to submit the advertisement. The discovery announcement message may include application code for proximity service communications.

[0071] Resource management module 315 can manage resource identification, request and/or control aspects for D2D proximity service communications. In some examples, resource management module 315 may determine whether type 1 or type 2 resources are associated with direct discovery operations. For type 1, resources may be allocated on a non-UE specific basis, for example via signaling in SIB 17. For example, a serving cell may provide UEs within its coverage area with a resource pool to be used to announce proximity service application codes. The serving cell may signal information associated with resource pooling in a SIB when device 115-b is in an RRC idle mode and via no-access stratum (NAS) signaling when device 115-b is in an RRC idle mode. connected from RRC. Resource management module 315 may randomly select a radio resource from the resource pool and use the selected radio resource to send the advertisement. For type 2, resources can be allocated on a per-UE specific basis when the UE is in an RRC connected mode. For example, a serving cell can signal resources via RRC signaling while in RRC connected mode. When the UE transitions to an RRC idle mode, the UE-specific resource can be released.

[0072] The 315 resource management module can determine whether mode 1 or mode 2 resources are associated with direct communication operations. For mode 1, communication resources are allocated on a UE-specific basis when the UE is in an RRC connected mode. The UE may request resources from the serving cell and the serving cell may respond with resources for transmitting scheduling assignment (or assignments) and data. The UE can request the resources by sending a Scheduling Request (SR) or Random Access message to the serving cell and a Staging Status Report (BSR). The BSR may carry information indicative of the data the UE needs to send and may also include an indication that the UE has data for direct communication in Proximity Service Communications and determine required resources. For mode 2, communication resources can be allocated on a non-EU specific basis. For example, the UE may randomly access an assigned pool of resources to transmit data and schedule assignment. The serving cell can allocate and configure the resources.

[0073] Resource management module 315 may identify, based on the ACB parameter, a resource for D2D proximity service communications. For example, the resource management module 315 may receive an indication from the ACB management module 305 of the assigned ACB parameter and whether lock operations are active. The resource management module 315 may receive an indication from the proximity service management module 310 of the proximity service function requirements, e.g., direct discovery, direct communications, etc. The resource management module 315 can identify if a resource is available based on the received indications, the RRC connection mode and the current configuration for discovery/communication resource allocation (type 1/mode 2 or type 2/mode 1 ). If a resource is identified as available, resource management module 315 may coordinate with RRC connection management module 320 to request the available resource.

[0074] RRC connection management module 320 can manage aspects of RRC functionality for device 115-b. For example, RRC connection management module 320 can manage RRC connections to device 115-b and output information indicative of the current RRC connection mode, for example, connected or idle. The RRC connection management module 320 may receive an indication from the resource management module 315, for example, that a resource is available and request the resource from the serving cell. For example, the RRC connection management module may send, via transmitter module 215-a, an RRC connection request message to the serving cell that includes an establishment cause associated with D2D Proximity Service communications. . The cause of establishment may be associated with the assigned ACB parameter. Exemplary establishment causes include, without limitation, D2D-discovery to establish a direct discovery connection to a normal priority UE, D2D-communication to establish a direct communication connection to a normal priority UE, D2D-discoveryhighprio to establish a connection for direct discovery to a high priority UE and/or D2D-communicationhighprio to establish a connection for direct communication to a high priority UE. The serving cell may therefore allocate the resource to the device 115-b for D2D proximity service communications based on the current blocking operation situation, blocking condition and establishment cause.

[0075] Figure 4 shows a system 400 for use in wireless communication, according to various examples. System 400 may include a UE 115-c, which may be an example of UEs 115 of Figure 1. UE 115-c may also be an example of one or more aspects of devices 115 of Figures 2 and 3.

[0076] The UE 115-c may generally include components for two-way voice and data communications that include components for transmitting communications and components for receiving communications. UE 115-c may include antenna (or antennas) 440, a transceiver module 435, a processor module 405, and memory 415 (which includes software (SW) 420), which can each communicate directly or indirectly, with each other (for example, via one or more buses 445). Transceiver module 435 can communicate bidirectionally, through antenna (or antennas) 440 and/or one or more wired or wireless links, with one or more networks, as described above. For example, the transceiver module 435 can bi-directionally communicate with base stations 105, with other UEs 115 and/or with devices 115 with reference to Figures 1, 2 or 3. The transceiver module 435 can include a modem for modulate the packets and deliver the modulated packets to antenna (or antennas) 440 for transmission, and to demodulate packets received from antenna (or antennas) 440. Although UE 115-c may include a single antenna 440, UE 115-c may have multiple antennas 440 capable of concurrently transmitting and/or receiving multiple wireless transmissions. Transceiver module 435 may be capable of communicating simultaneously with one or more base stations 105 via multiple component carriers.

[0077] The UE 115-c may include an ACB module 410, which may perform the functions described above for the ACB module 210 of the devices 115 of Figures 2 and 3. The UE 115-c may also include a status module lock status module 450. Lock status module 450 may monitor, control and/or otherwise manage aspects of lock operations for UE 115-c for D2D proximity service communications. The deadlock status module 450 can determine a deadlock status for a serving cell of the UE 115-c, an ACB parameter for the device 115-c associated with D2D proximity service communications, a proximity service, and an RRC connection mode for the 115-c device. Block status module 450 may identify and/or request a resource available for D2D proximity service communications from a serving cell, e.g., base station 105-a. The resource can be identified based on the assigned ACB parameter and blocking condition. The facility may be used for D2D communications with UE 115-d, for example, for one or more proximity service functions.

[0078] In some examples, the blocking status module 450 may manage state transitions for UE 115-c. During blocking operations, UE 115-c may transition from an unblocked state and vice versa. Block status module 450 can determine one or more provisions related to transition state management through upper layers, e.g., instructing an upper layer protocol not to send data when a block operation indicates that service communications D2D proximity ranges are blocked. For non-blocking to blocking transitions, the blocking situation module 450 may, for type 1 discovery operations, remove radio resource information from a media access controller (MAC) when a SIB 1 message remove otherwise allocated resources. This can be done when UE 115-c is in an RRC connected mode. The lock status module 450 may, for type 2 discovery operations, remove radio resource information when in an RRC connected mode. This can provide a proximity service protocol to send a trigger (for example, an indication that proximity services are pending) and an RRC protocol can reject the trigger.

[0079] Blocking situation module 450 may, for mode 1 communication operations, and when UE 115-c is in an RRC connected mode and blocking is active, control the RRC protocol to prevent the MAC protocol to submit a temporary storage status report. For mode 2 communication operations, the RRC protocol can remove a radio resource indication from a MAC protocol to prevent information from being sent to the serving cell.

[0080] Memory 415 can include Random Access Memory (RAM) and Read Only Memory (ROM). Memory 415 may store computer-executable, computer-readable software/firmware code 420 that contains instructions that, when executed, cause processor module 405 to perform the various functions described herein (e.g., receiving parameter from ACB , identify resource availability for D2D Proximity Service communications, request available resource for discovery and/or communication operations, etc.). Alternatively, the computer executable and computer readable software/firmware code 420 may not be directly executable by processor module 405, but having a computer (eg, when compiled and executed) perform functions described herein. Processor module 405 may include an intelligent hardware device, for example, a central processing unit (CPU), a microcontroller, an application-specific integrated circuit (ASIC), and the like.

[0081] Figure 5 shows a block diagram 500 of an apparatus 105-b for use in wireless communication, in accordance with various aspects of the present disclosure. In some examples, apparatus 105-b may be exemplary aspects of one or more of the base stations 105 described with reference to Figures 1, 2, 3 or 4. In some examples, apparatus 105-b may form part or include an LTE/LTE-A eNB and/or an LTE/LTE-A base station. Apparatus 105-b may also be a processor. Apparatus 105-b may include a receiver module 505, a lock management module 510 and/or a transmitter module 515. Each of these modules may be in communication with one another.

[0082] The components of apparatus 105-c may, individually or collectively, be deployed using one or more ASICs adapted to perform some or all of the applicable functions in hardware. Alternatively, functions may be performed by one or more processing units (or cores) on one or more integrated circuits. In other examples, other types of integrated circuits may be used (eg, structured/platform ASICs, FPGAs, and other semi-custom ICs), which may be programmed in any manner known in the art. The functions of each component can also be implemented, totally or partially, with instructions incorporated in a memory, formatted to be executed by one or more processors of general or specific application.

[0083] In some examples, the receiver module 505 may include at least one radio frequency (RF) receiver, such as an RF receiver operable to receive discovery and/or communication signals related to D2D proximity service communication from a serving cell associated with blocking operations for D2D proximity service communications, etc. Receiver module 505 can be used to receive various types of data and/or control signals (i.e., transmissions) over one or more communication links of a wireless communication system, such as one or more system communication links. wireless communications hub 100 described with reference to Figure 1.

[0084] In some examples, transmitter module 515 may include at least one RF transmitter, such as at least one RF transmitter operable to transmit discovery and/or communication signals related to proximity service communication to an associated serving cell to resource request and blocking operations for D2D proximity service communications, etc. Transmitter module 515 can be used to transmit various types of ProSe discovery data and/or control signals (i.e., transmissions) over one or more communication links of a wireless communication system, such as one or more communication links of the wireless communication system 100 described with reference to Figure 1.

[0085] In some examples, lock management module 510 can manage one or more functions for lock operations for UEs participating in D2D proximity service communications. The lock management module 510 may determine an ACB parameter for UEs within the coverage area of the apparatus 105-b that applies to D2D proximity service communications. For example, the lock management module 510 can determine an ACB parameter for discovery operations for normal priority UEs, for direct communication operations for normal priority UEs, for direct discovery operations for high priority UEs, and/or for direct communication operations to high priority UEs. The lock management module 510 can communicate the ACB parameters to UEs within its coverage area via a SIB2 message, for example.

[0086] In some examples, lock management module 510 may communicate information associated with lock operations, for example, active lock operations. The lockout management module 510 can determine whether the lockout is active and, if so, what lockout condition is associated with the lockout operations, e.g., emergency, utilities, security services, network maintenance and congestion, etc. When lockout operations are enabled, lockout management module 510 may send one or more signals to UEs within its coverage area that indicate that the lockout is active and the associated lockout condition.

[0087] In some examples, the lock management module 510 can manage one or more aspects related to resource management. For example, lock management module 510 may allocate Type 1 and/or Type 2 discovery resources as well as Mode 1 and/or Mode 2 communication resources for D2D proximity service communications. The lock management module 510 can receive a request for resources from a UE and allocate the associated resource depending on the associated resource, the ACB parameter assigned to the UE and the current lock operation situation/lock condition. In some examples, lock management module 510 may remove information associated with a radio resource in a pool of available resources from SIB message 17 when lock operations prevent allocation.

[0088] Figure 6 shows a block diagram 600 of an apparatus 105 for use in wireless communication, in accordance with various aspects of the present disclosure. In some examples, apparatus 105-c may be exemplary aspects of one or more of the base stations 105 described with reference to Figures 1, 2, 3, or 4 and/or exemplary aspects of apparatus 105-b described with reference to Figure 5 . In some examples, apparatus 105-c may form part of or include an LTE/LTE-A eNB and/or an LTE/LTE-A base station. Apparatus 105-c may also be a processor. Apparatus 105-c may include a receiver module 505-a, a lock management module 510-a, and/or a transmitter module 515-a. Each of these modules can be in communication with each other. The lock management module 510-a may include an ACB control module 605 and a resource management module 610. The receiver module 505-a and the transmitter module 515-a may perform the functions of the receiver module 505 and the transmitter module 515 of Figure 5 , respectively.

[0089] The components of apparatus 105-c may, individually or collectively, be deployed using one or more ASICs adapted to perform some or all of the applicable functions in hardware. Alternatively, functions may be performed by one or more processing units (or cores) on one or more integrated circuits. In other examples, other types of integrated circuits may be used (eg, structured/platform ASICs, FPGAs, and other semi-custom ICs), which may be programmed in any manner known in the art. The functions of each component can also be implemented, totally or partially, with instructions incorporated in a memory, formatted to be executed by one or more processors of general or specific application.

[0090] In some examples, the ACB 605 control module can manage various functions for access class blocking operations for D2D Proximity Service communications. The ACB control module 605 can determine ACB parameters for UEs within the coverage area of apparatus 105-c for D2D proximity service communications, for example, ACB parameters for discovery operations and/or direct communication to UEs normal priority as well as direct discovery/communication operations to high priority UEs. The ACB control module 605 can, in cooperation with the transmitter module 515-a, communicate the ACB parameters to the UEs within its coverage area via a SIB2 message, for example. The ACB 605 control module can also determine whether blocking is active and, if so, what blocking condition is associated with blocking operations. When the blocking operations are activated, the ACB control module 605 can send one or more signals, through the transmitter module 515-a, to the UEs within its coverage area indicating that the blocking is active and the condition of associated lock.

[0091] In some examples, resource management module 610 may manage one or more aspects related to resource management. For example, resource management module 610 may allocate discovery and/or communication resources for D2D proximity service communications in response to a request for resources from a UE. The resource management module 610 can allocate the associated resource depending on the associated resource, the ACB parameter assigned to the UE and the current blocking operation situation/blocking condition. In some examples, the resource management module 610 may remove information associated with a radio resource in a grouping of available resources. For example, resource management module 610 can remove information associated with a non-UE specific grouping of discovery and/or communication specific resources communicated to UEs (e.g., in a SIB message 17). The resource management module 610 can remove information in response to blocking operations that are active and the blocking condition that indicates that the resource pool is not allocable to the UEs.

Base station 105-d may, for example, include multiple base station antennas 745 (e.g., an array of antennas). Base station 105-d can communicate with main network 130-a through network communications module 775. Base station 105-d can also communicate with other base stations, such as base stations 705-d. m and 705-n, using the 765 base station communications module.

[0098] Figure 8 is a lane diagram 800 illustrating aspects of D2D proximity service communications in accordance with various aspects of the present disclosure. Diagram 800 may illustrate aspects of system 100, 400 and/or 700 described with reference to Figures 1, 4 or 7, respectively. The diagram 800 includes a UE 805 and a serving cell 810. The UE 805 may be an example of one or more of the UEs 115 and/or devices 115 described above with respect to Figures 1, 2, 3 and/or 4. The cell server cell 810 may be an example of one or more of the base stations 105 and/or apparatus 105 described above with respect to Figures 1, 5, 6 and/or 7. In some examples, server cell 810 may be a server cell of the UE 805. Generally speaking, diagram 800 illustrates aspects for implementing access class blocking operations for D2D proximity service communications. In some examples, a system device, such as one of UEs 115 and/or base stations 150, may execute one or more sets of codes to control functional elements of the device to perform some or all of the functions described below.

[0099] At block 815, serving cell 810 may determine an ACB parameter for UEs within its coverage area, for example, UE 805, for D2D proximity service communications. The ACB parameter can be associated with discovery operations and/or communications for normal priority UEs and for high priority UEs. The ACB parameter can be provided to access certain resources of the serving cell 810 when blocking operations are active and a UE requests such resources. At block 820, serving cell 810 may transmit, communicate, or otherwise transport the ACB parameter to UE 805. Serving cell 810 may send the ACB parameter to UE 805 via a SIB, e.g., SIB of type 2.

[0100] At block 825, the UE 805 may process the message from the serving cell 810 and identify the availability of a resource for D2D proximity service communications. As an example, serving cell 810 may assign an ACB parameter for discovery and communication operations for UEs of normal priority to UE 805. Consequently, when blocking is active for discovery operations for UEs of normal priority, UE 805 may determine that no resource is available, and therefore refrain from taking action to request the resource, for example, refrain from submitting a BSR.

[0101] Figure 9 is a lane diagram 900 illustrating aspects of D2D proximity service communications in accordance with various aspects of the present disclosure. Diagram 900 may illustrate aspects of system 100, 400 and/or 700 described with reference to Figures 1, 4 or 7, respectively. The diagram 900 includes a UE 905 and a serving cell 910. The UE 905 may be an example of one or more of the UEs 115 and/or devices 115 described above with respect to Figures 1, 2, 3 and/or 4. The cell server cell 910 may be an example of one or more of the base stations 105 and/or apparatus 105 described above with respect to Figures 1, 5, 6 and/or 7. In some examples, server cell 910 may be a server cell of the UE 905. Generally speaking, diagram 900 illustrates aspects for implementing access class blocking operations for D2D proximity service communications. In some examples, a system device, such as one of UEs 115 and/or base stations 150, may execute one or more sets of codes to control functional elements of the device to perform some or all of the functions described below.

[0102] At block 915, serving cell 910 may determine an ACB parameter for UEs within its coverage area, for example, UE 905, for D2D proximity service communications. The ACB parameter can be associated with discovery operations and/or communications for normal priority UEs and for high priority UEs. At block 920, serving cell 910 may send the ACB parameter to UE 905 in a SIB2 message, for example.

[0103] In block 925, UE 905 may process the message and identify the availability of a resource for D2D proximity service communications. As an example, serving cell 910 may assign an ACB parameter for discovery and communication operations for high priority UEs to UE 905. Consequently, when blocking is active for discovery operations for normal priority UEs (but not for UEs high priority), UE 905 may identify that a resource is available. In block 930, UE 905 may determine an establishment cause for requesting the identified available resource. The establishment cause may correspond to the assigned ACB parameter, for example, an establishment cause that requests resource discovery operations for high priority UEs. In block 935, the UE 905 sends an RRC connection request message to the serving cell 910. The RRC connection request message includes the establishment cause and informs the serving cell 910 that the UE 905 is requesting an available resource under the current blocking conditions. Accordingly, serving cell 910 may allocate the resource to UE 905 for D2D proximity service communications.

[0104] Figure 10 is a lane diagram 1000 illustrating aspects of D2D proximity service communications in accordance with various aspects of the present disclosure. Diagram 1000 may illustrate aspects of system 100, 400 and/or 700 described with reference to Figures 1, 4 or 7, respectively. The diagram 1000 includes a UE 1005 and a serving cell 1010. The UE 1005 may be an example of one or more of the UEs 115 and/or devices 115 described above with respect to Figures 1, 2, 3 and/or 4. The cell server cell 1010 may be an example of one or more of the base stations 105 and/or apparatus 105 described above with respect to Figures 1, 5, 6 and/or 7. In some examples, server cell 1010 may be a server cell of the UE 1005. Generally speaking, diagram 1000 illustrates aspects for implementing access class blocking operations for D2D proximity service communications with the various protocols of UE 1005. In some examples, a system device such as one of the UEs 115 and/or base stations 150, may execute one or more sets of codes to control the functional elements of the device to perform some or all of the functions described below.

[0105] The UE 1005 may include a proximity service protocol 1015, a non-access layer (NAS) 1020, a radio resource control (RRC) 1025, and a media access control (MAC) 1030. such components may represent one or more protocols, layers and/or functions in operation at UE 1005. In some examples, the components may be implemented by a processor module (e.g., processor module 405) of UE 1005 that executes codes or instructions for performing the functions described below.

[0106] At block 1035, the serving cell 1010 may send a SIB2 message to the UE 1005 (e.g., the RRC 1025) which indicates that the blocking operations of the serving cell 1010 are active. In accordance with the functions discussed above, the UE 1005 may have been assigned an ACB parameter that indicates its ability to access resources when blocking operations are active, depending on its assigned ACB parameter and the blocking condition. The message from SIB2 can, as shown in Figure 10, indicate that UE 1005 is blocked from accessing resources. Consequently, in block 1040 the RRC 1025 may process the SIB2 message and determine that the UE 1005 is blocked from accessing one or more resources. At block 1045, RRC 1025 may send a signal to Proximity Service Protocol 1015 that includes information indicating that certain resources are blocked from D2D Proximity Service communications in accordance with the blocked condition. As a result, the RRC 1025 can inform the proximity service protocol 1015 directly of the blocked indication. In some instances where the UE 1005 is in an RRC connected mode, the RRC 1025 may send the service request rejection message directly to the proximity service 1015 for direct discovery type 2 facilities.

[0107] In some examples, the functions of the UE 1005 shown in Figure 10 can be performed while the UE 1005 is in an RRC connected mode or an RRC idle mode and the resources implied can be for type 1 direct discovery resources In some examples, the functions of the UE 1005 shown in Figure 10 can be performed while the UE 1005 is in an RRC connected mode and the resources implied can be for type 2 direct discovery resources. UE 1005 shown in Figure 10 can be performed while the UE 1005 is in an RRC connected mode or an RRC idle mode and the resources implied can be for mode 2 direct communication resources.

[0108] Figure 11 is a lane diagram 1100 illustrating aspects of D2D proximity service communications in accordance with various aspects of the present disclosure. Diagram 1100 may illustrate aspects of system 100, 400 and/or 700 described with reference to Figures 1, 4 or 7, respectively. The diagram 1100 includes a UE 1105 and a serving cell 1110. The UE 1105 may be an example of one or more of the UEs 115 and/or devices 115 described above with respect to Figures 1, 2, 3 and/or 4. The cell server cell 1110 may be an example of one or more of the base stations 105 and/or apparatus 105 described above with respect to Figures 1, 5, 6 and/or 7. In some examples, server cell 1110 may be a server cell of the UE 1105. Generally speaking, diagram 1100 illustrates aspects for implementing access class blocking operations for D2D proximity service communications with the various protocols of UE 1105. In some examples, a system device such as one of the UEs 115 and/or base stations 150, may execute one or more sets of codes to control the functional elements of the device to perform some or all of the functions described below.

[0109] The UE 1105 may include a proximity service protocol 1115, a non-access layer (NAS) 1120, a radio resource control (RRC) 1125, and a media access control (MAC) 1130. such components may represent one or more protocols, layers and/or functions in operation at UE 1105. In some examples, the components may be implemented by a processor module (e.g., processor module 405) of UE 1105 that executes codes or instructions for performing the functions described below.

[0110] At block 1135, the serving cell 1110 may send a SIB2 message to the UE 1105 (e.g., the RRC 1125) which indicates that the blocking operations of the serving cell 1110 are active. In accordance with the functions discussed above, the UE 1105 may have been assigned an ACB parameter that indicates its ability to access resources when blocking operations are active, depending on its assigned ACB parameter and the blocking condition. The message from SIB2 can, as shown in Figure 11, indicate that UE 1105 is blocked from accessing resources. Consequently, in block 1140 the RRC 1125 may process the SIB2 message and determine that the UE 1105 is blocked from accessing one or more resources.

[0111] At block 1145, the Proximity Service Protocol 1115 may determine that a Proximity Service communication may be required and send a Service Request message to the NAS 1120 to be forwarded to the RRC 1125. The Service Request may include an application code for the proximity service and may be used to request RRC 1125 to establish a connection using the appropriate resource. At block 1155, the RRC may send a service request rejection message to the NAS 1120 to be forwarded to the proximity service protocol 1115. The service request rejection message may implement the blocking operation with the UE 1105 and prevent Proximity Service Protocol 1115 from requesting or accessing blocked resources. The service request rejection message may include information that indicates that certain resources are blocked from D2D proximity service communications, as per the blocked condition. Accordingly, the RRC 1125 may inform the proximity service protocol 1115 of the blocked indication via the service request rejection message via the NAS 1120.

[0112] In some examples, the functions of the UE 1105 shown in Figure 11 can be performed while the UE 1105 is in an idle RRC mode and the resources implied can be for type 2 direct discovery resources. functions of the UE 1105 shown in Figure 11 can be performed while the UE 1105 is in an RRC connected mode or an RRC idle mode and the resources implied can be for mode 1 direct communication resources.

[0113] Figure 12 is a lane diagram 1200 illustrating aspects of D2D proximity service communications in accordance with various aspects of the present disclosure. Diagram 1200 may illustrate aspects of system 100, 400 and/or 700 described with reference to Figures 1, 4 or 7, respectively. The diagram 1200 includes a UE 1205 and a serving cell 1210. The UE 1205 may be an example of one or more of the UEs 115 and/or devices 115 described above with respect to Figures 1, 2, 3 and/or 4. The cell server cell 1210 may be an example of one or more of the base stations 105 and/or apparatus 105 described above with respect to Figures 1, 5, 6 and/or 7. In some examples, server cell 1210 may be a server cell of the UE 1205. Generally speaking, diagram 1200 illustrates aspects for implementing access class blocking operations for D2D proximity service communications with the various protocols of UE 1205. In some examples, a system device such as one of the UEs 115 and/or base stations 150, may execute one or more sets of codes to control the functional elements of the device to perform some or all of the functions described below.

[0114] The UE 1205 may include a proximity service protocol 1215, a non-access layer (NAS) 1220, a radio resource control (RRC) 1225, and a media access control (MAC) 1230. such components may represent one or more protocols, layers and/or functions in operation at UE 1205. In some examples, the components may be implemented by a processor module (e.g., processor module 405) of UE 1205 that executes code or instructions for performing the functions described below.

[0115] At block 1235, the serving cell 1210 may send a SIB2 message to the UE 1205 (e.g., the RRC 1225) that indicates that the blocking operations of the serving cell 1210 are active. In accordance with the functions discussed above, the UE 1205 may have been assigned an ACB parameter that indicates its ability to access resources when blocking operations are active, depending on its assigned ACB parameter and the blocking condition. The SIB2 message can, as shown in Figure 12 , indicate that UE 1205 is blocked from accessing resources. Consequently, in block 1240 the RRC 1225 may process the SIB2 message and determine that the UE 1205 is blocked from accessing one or more resources. At block 1245, the RRC 1225 may send a signal to the MAC 1230 that removes information associated with radio resources for the resources for D2D proximity service communications, in accordance with the blocked condition. For example, the serving cell 1210 can provide information associated with radio resources for a resource grouping in a SIB message 17. The RRC 1225 can process the SIB message 17 and remove the information associated with radio resources to implement the situation blocked for UE 1205. Consequently, UE 1205 can effectively refrain from processing the SIB message 17 if blocking operations are active and UE 1205 is blocked. In some examples, the functions of the UE 1205 shown in Figure 12 can be performed while the UE 1005 is in an RRC connected mode or RRC idle mode and the resources implied can be for type 1 direct discovery resources and for Mode 2 communication.

[0116] Figure 13 is a lane diagram 1300 illustrating aspects of D2D proximity service communications in accordance with various aspects of the present disclosure. Diagram 1300 may illustrate aspects of system 100, 400 and/or 700 described with reference to Figures 1, 4 or 7, respectively. The diagram 1300 includes a UE 1305 and a serving cell 1310. The UE 1305 may be an example of one or more of the UEs 115 and/or devices 115 described above with respect to Figures 1, 2, 3 and/or 4. The cell server cell 1310 may be an example of one or more of the base stations 105 and/or apparatus 105 described above with respect to Figures 1, 5, 6 and/or 7. In some examples, server cell 1310 may be a server cell of the UE 1205. Generally speaking, diagram 1300 illustrates aspects for implementing access class blocking operations for D2D proximity service communications by serving cell 1310. In some examples, a system device such as one of the UEs 115 and/or base stations 150, may execute one or more sets of codes to control functional elements of the device to perform some or all of the functions described below.

[0117] The UE 1305 may include a proximity service protocol 1315, a non-access layer (NAS) 1320, a radio resource control (RRC) 1325, and a media access control (MAC) 1330. such components may represent one or more protocols, layers and/or functions in operation at UE 1305. In some examples, the components may be implemented by a processor module (e.g., processor module 405) of UE 1305 that executes codes or instructions for performing the functions described below.

[0118] At block 1335, the serving cell 1310 may send a SIB2 message to the UE 1305 (e.g., the RRC 1325) that indicates that the blocking operations of the serving cell 1310 are active. In accordance with the functions discussed above, the UE 1305 may have been assigned an ACB parameter that indicates its ability to access resources when blocking operations are active, depending on its assigned ACB parameter and the blocking condition. The SIB2 message can, as shown in Figure 13 , indicate that UE 1305 is blocked from accessing resources. Consequently, in block 1340 the RRC 1325 may process the SIB2 message and determine that the UE 1305 is blocked from accessing one or more resources. the serving cell 1310 can, based on the SIB2 message, know that the UE 1305 has been blocked from accessing the resources for D2D proximity service communications. Consequently, at block 1345, the serving cell 1310 may remove information associated with radio resources for a resource pool from a SIB message 17 and send the SIB message 17 to the UE 1305 at block 1350. Consequently, the UE 1305 may not access resources from the resource pool.

[0119] Figure 14 is a flow chart illustrating an example of a method 1400 for wireless communication in accordance with various aspects of the present disclosure. For clarity, method 1400 is described below with reference to aspects of one or more of the UEs 115 described with reference to Figures 1, 8, 9, 10, 11, 12, or 13 and/or aspects of one or more of the devices described with reference to Figures 2, 3 or 4 . In some examples, a UE may execute one or more sets of codes to control functional elements of the UE to perform the functions described below. Additionally or alternatively, the UE may perform one or more of the functions described below with the use of special purpose hardware.

[0120] In block 1405, method 1400 may include the UE that receives a message from a serving cell. The message may include information indicative of an ACB parameter for D2D proximity service communications. The ACB parameter can be associated with discovery or communication operations for normal priority UEs and for high priority UEs. At block 1410, the UE may identify, based at least in part on the ACB parameter, a resource availability for D2D proximity service communications. For example, the UE can identify resource availability based on the assigned ACB parameter, which blocking operations are active, the type of resource required for D2D proximity service communications, and the blocking conditions it has secured. the blocking operation.

[0121] The operation (or operations) in blocks 1405 and 1410 can be performed using the ACB module 205/410 described with reference to Figures 2, 3 or 4.

[0122] In this way, method 1400 can provide wireless communication. It should be noted that method 1400 is only an implementation and that the operations of method 1400 can be rearranged or otherwise modified so that other implementations are possible.

[0123] Figure 15 is a flow chart illustrating an example of a method 1500 for wireless communication in accordance with various aspects of the present disclosure. For clarity, method 1500 is described below with reference to aspects of one or more of the base stations, handsets, and/or serving cells described with reference to Figures 1, 6, 7, 8, 9, 10, 11, 12, or 13. In some examples, a base station may execute one or more sets of codes to control functional elements of the UE to perform the functions described below. Additionally or alternatively, the base station may perform one or more of the functions described below using special purpose hardware.

[0124] In block 1505, method 1500 may include the base station determining an ACB parameter for D2D proximity service communications. The ACB parameter can be associated with discovery or communication operations for normal priority UEs and for high priority UEs. At block 1510, the base station may send a message to at least one mobile device (UE). The message may include information indicative of the ACB parameter for D2D proximity service communications. The message can be sent in a SIB2 message.

[0125] The operation (or operations) in blocks 1505 and 1510 can be performed using the lock management module 510/710 described with reference to Figures 5, 6 or 7.

[0126] Therefore, method 1500 can provide wireless communication. It should be noted that method 1500 is only one deployment and that the operations of method 1500 can be rearranged or otherwise modified so that other deployments are possible.

[0127] Figure 16 is a flow chart illustrating an example of a method 1600 for wireless communication in accordance with various aspects of the present disclosure. For clarity, method 1600 is described below with reference to aspects of one or more of the UEs 115 described with reference to Figures 1, 8, 9, 10, 11, 12 or 13, and/or aspects of one or more of the devices described with reference to Figures 2, 3 or 4 . In some examples, a UE may execute one or more sets of codes to control functional elements of the UE to perform the functions described below. Additionally or alternatively, the UE may perform one or more of the functions described below with the use of special purpose hardware.

[0128] In block 1605, method 1600 may include the UE that receives a message from a serving cell. The message may include information indicative of an ACB parameter for D2D proximity service communications. The ACB parameter can be associated with discovery or communication operations for normal priority UEs and for high priority UEs. At block 1610, the UE may identify, based at least in part on the ACB parameter, a resource availability for D2D proximity service communications. For example, the UE can identify resource availability based on the assigned ACB parameter, which blocking operations are active, the type of resource required for D2D proximity service communications, and the blocking conditions it has secured. the blocking operation. At block 1615, the UE can determine if a resource is available based on the identified resource. For example, if blocking is active and the assigned ACB parameter does not allow the UE to access the relevant resource, the UE may determine that no resource is available and accordingly, in block 1620 the UE may determine that proximity service communications of D2D are prohibited or otherwise blocked.

[0129] If, however, the UE determines that a resource is available, at block 1625, the UE may determine a cause of establishment associated with D2D proximity service communications. For example, the establishment cause can correspond to the assigned ACB parameter and be associated with discovery and/or communication resources for normal priority and high priority UEs. At block 1630, the UE may send an RRC connection request or establishment message to the serving cell. The RRC connection request message may include the establishment cause for requesting the available resource.

[0130] The operation (or operations) in blocks 1605, 1610, 1615, 1620, 1625 and 1630 can be performed using the ACB module 205/410 described with references to Figures 2, 3 or 4.

[0131] In this way, method 1600 can provide wireless communication. It should be noted that method 1600 is only an implementation and that the operations of method 1600 may be rearranged or otherwise modified so that other implementations are possible.

[0132] In some examples, aspects of two or more of methods 1400, 1500 and/or 1600 may be combined. It should be noted that methods 1400, 1500 and 1600 are exemplary implementations only, and that the operations of methods 1400-1600 can be rearranged or otherwise modified so that other implementations are possible.
