In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.
With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of the services in future life, the third generation partnership project (3) rd Generation Partnership Project,3 GPP) the international organization for standardization began developing 5G. The main application scenarios of 5G are: enhanced Mobile Ultra wide band (eMBB), low-Latency high-reliability communication (URLLC), and massive Machine-Type communication (mMTC).
On the one hand, the eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said that it must be analyzed in detail in conjunction with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.
In early NR deployment, complete NR coverage is difficult to obtain, so typical network coverage is wide-area LTE coverage and isolated island coverage pattern of NR. Moreover, a large amount of LTE is deployed below 6GHz, and the spectrum below 6GHz available for 5G is rare. NR must therefore be studied for spectrum applications above 6GHz, with limited high band coverage and fast signal fading. Meanwhile, in order to protect the early LTE investment of a mobile operator, a light interworking (TIGHT) working mode between LTE and NR is provided.
In 5G, the maximum channel bandwidth may be 400MHZ (referred to as wideband carrier), which is large compared to the LTE maximum 20M bandwidth. The power consumption of the terminal device is very large if the terminal device remains operating on the wideband carrier. It is therefore proposed that the Radio Frequency (RF) bandwidth of the terminal device can be adjusted according to the actual throughput of the terminal device. To this end, the concept of bandwidth Part (BWP) was introduced, the motivation of which was to optimize the power consumption of the end devices. For example, if the velocity of the terminal device is low, the terminal device may be configured with a slightly smaller BWP (as shown in fig. 2-1), and if the velocity requirement of the terminal device is high, the terminal device may be configured with a slightly larger BWP (as shown in fig. 2-2). If the terminal device supports high rates or operates in Carrier Aggregation (CA) mode, the terminal device may be configured with multiple BWPs (as shown in fig. 2-3). Another purpose of BWP is to trigger coexistence of multiple base parameter sets (numerology) in a cell, BWP1 for numerology1 and BWP2 for numerology2 as shown in fig. 2-3.
The idle state or inactive state of the terminal device resides on an initial BWP (initial BWP), which is visible to the idle state or inactive state of the terminal device, and the terminal device can obtain a Master Information Block (MIB), remaining Minimum System Information (RMSI), other System Information (OSI), and paging (paging) Information from the initial BWP.
For a connected ue, up to 4 uplink BWPs and up to 4 downlink BWPs can be configured for a ue through Radio Resource Control (RRC) dedicated signaling, but only one uplink BWP and one downlink BWP can be activated at the same time. In RRC dedicated signaling, a first active BWP of the configured BWPs may be indicated. Meanwhile, in the process that the terminal is in the connected state, the terminal can also switch between different BWPs through Downlink Control Information (DCI). When the carrier in the inactive state enters the active state, the first active BWP is the first active BWP configured in the RRC dedicated signaling. The configuration parameters for each BWP include:
-Subcarrier Spacing (SCS);
-Cyclic Prefix (Cyclic Prefix);
-the first Physical Resource Block (PRB) and the number of consecutive PRBs (locationAndBandwidth) of the BWP;
-BWP identification (BWP-Id);
-BWP Common configuration parameters (BWP-Common) and BWP Dedicated configuration parameters (BWP-Dedicated).
The terminal device only executes on the active BWP during Radio Link Monitor (RLM), the inactive BWP does not need to operate, and the timer and counter related to RLM do not need to be reset when switching between different BWPs. For Radio Resource Management (RRM) measurement, RRM measurement is not affected no matter which activated BWP the terminal device receives and transmits data on. For the measurement of Channel Quality Indication (CQI), the terminal device also only needs to perform on active BWP.
When a carrier is deactivated, and then the carrier is activated through a Media Access Control Element (MAC CE), the initial first activated BWP is the first activated BWP configured in the RRC dedicated signaling.
The BWP identification (BWP id) takes values from 0 to 4 in the RRC dedicated signaling, and the BWP with the BWP identification of 0 is defaulted as the initial BWP.
A BWP indicator (BWP indicator) is 2 bits (bit) in DCI, as shown in table 1 below. And if the number of the configured BWPs is less than or equal to 3, BWP indicators =1,2,3 correspond to BWP id =1,2,3 respectively. If the number of BWPs is 4, BWP indicator =0,1,2,3 corresponds to the BWPs sequentially indexed and arranged. And the network side uses the continuous BWP id in configuring BWP.
TABLE 1
In LTE carrier aggregation, states of an SCell are classified into an active state, a deactivated state, and a sleep (dormant) state. In the NR, in order to quickly activate the SCell and reduce the activation time delay of the SCell, a dormancy behavior of the SCell is determined to be introduced, and the dormancy behavior is different from a sleep state and belongs to an activation state.
The SCell behavior in the NR is implemented by a dormant BWP, where the dormant BWP is a dedicated Downlink BWP configured by an RRC dedicated signaling, and the terminal device does not monitor a Physical Downlink Control Channel (PDCCH) on the dormant BWP, but performs Channel State Information (CSI) measurement and reporting, AGC and beam (beam) management, and the like.
For Downlink, the terminal device does not perform PDCCH and Physical Downlink Shared Channel (PDSCH) reception on the Downlink BWP, which needs to be implemented by not configuring PDCCH resources, PDSCH resources, and Semi-Persistent Scheduling (SPS) resources on the Downlink BWP. But requires CSI measurement, beam management, beam Failure Detection (BFD), and Beam Failure Recovery (BFR) to be implemented on the dormant BWP. Thus, channel State Information-Reference Signal (CSI-RS) Configuration, transmission Configuration Indication-State (TCI-State) Configuration, and BFD-RS and BFR related configurations may be configured on a downlink BWP.
For uplink, there are two candidates to support the dormant BWP. Firstly, defining an uplink dormant BWP, and restricting the uplink behavior of the dormant BWP by configuring the uplink dormant BWP; secondly, the uplink dormant BWP is not defined, and the uplink behavior of the dormant BWP is restrained through a protocol. The latter is a protocol-prone choice.
The types of CSI reports (CSI report) are periodic CSI reports, semi-persistent CSI reports, and aperiodic CSI reports. In principle, any CSI reporting type may be transmitted over the SCell with non-dormant behavior. However, considering that the aperiodic CSI reporting may cause a problem of power consumption of the terminal device, the aperiodic CSI reporting is not supported when the terminal device enters the dormant BWP of the SCell.
The terminal equipment enters dormant BWP on the SCell, i.e. enters dormant behavior. And leaving the dormant BWP, namely leaving dormant behavior, and entering a data transceiving state. This procedure is implemented by a BWP handover procedure. In order to effectively control the dormant behaviors of all the SCells of the terminal equipment, a network side can configure different SCell groups through dedicated signaling, all the SCells belonging to one SCell group share dormancy indication information of one network side, and the network side issues the dormancy indication information through DCI. In addition, in order to flexibly control the dormant behavior of each SCell, the network side may also issue sleep indication information for each SCell through DCI.
The dormant behavior is part of the activation state, and the SCell with dormant behavior may be commanded to enter the deactivation state by activating/deactivating the MAC CE. Meanwhile, the activation/deactivation MAC CE may also command the SCell in the deactivated state to enter the activated state, and further, the SCell entering the activated state will first enter the initial activation BWP configured by the RRC (i.e., the BWP indicated by the first active downlink BWP-Id).
SRS transmission may be supported on the downlink BWP, which is expected to support long-period SRS transmission for the purpose of power saving of the terminal device. According to the difference of SCS of the dormant BWP configuration, the SRS period configurable by the dormant BWP is different, so that how to configure the SRS configuration of the dormant BWP is a definite problem. Therefore, the following technical scheme of the embodiment of the application is provided.
Fig. 3 is a flowchart illustrating a SRS configuration method according to an embodiment of the present application, where as shown in fig. 3, the SRS configuration method includes the following steps:
step 301: the method comprises the steps that network equipment sends first configuration information to terminal equipment, wherein the first configuration information is used for determining SRS configuration of a dormant BWP, the SRS configuration comprises a first SRS period, and the first SRS period is used for the terminal equipment to send SRS periodically on the dormant BWP.
In the embodiment of the application, the network device sends the first configuration information to the terminal device, and accordingly, the terminal device receives the first configuration information sent by the network device. In an alternative, the network device may be a base station, such as a gbb.
In this embodiment of the application, the first configuration information is used to determine an SRS configuration of the dormant BWP, where the SRS configuration includes a first SRS period, and the first SRS period is used for the terminal device to periodically send an SRS on the dormant BWP. Here, after receiving the first configuration information, the terminal device may determine an SRS configuration based on the first configuration information, where the SRS configuration includes at least a first SRS period, and the terminal device periodically transmits SRS on the downlink BWP according to the first SRS period.
In the embodiment of the present application, the configuration information of the SRS period may be referred to as shown in table 2 below,
TABLE 2
In table 2, the SRS period is configured according to the number of slots (slots), for example, SI80 represents that the SRS period is 80 slots, and SI160 represents that the SRS period is 160 slots.
In the embodiment of the present application, here, the SCS of the dormant BWP configuration is determined based on a first SCS set, which includes candidate SCS of at least one of the dormant BWPs. Specifically, the network device determines a first SCS set that includes candidate SCS's for at least one of the dormant BWPs; the network device selects a candidate SCS from the first SCS set, and configures the candidate SCS as the SCS of the dormant BWP. Here, in an alternative, the first SCS set is determined based on a protocol.
Here, for the dormant BWP, the configurable SCS (i.e., candidate SCS) is constrained to a fixed one or more, which form a first set of SCS, optionally specified by the protocol. For example: the first SCS set includes 15kHz subcarrier spacing, 30kHz subcarrier spacing, that is, for dormant BWP, the configurable SCS can only be either 15kHz subcarrier spacing or 30kHz subcarrier spacing.
In the embodiment of the present application, the time slot lengths corresponding to different SCS are different, for example, the time slot length corresponding to 15kHz subcarrier interval is 1ms, and the time slot length corresponding to 30khz subcarrier interval is 0.5ms. Since the SRS periods are configured according to the number of slots (see table 1 above), however, the slot lengths corresponding to different SCS are different, so there is a disadvantage in configuring the SRS periods according to the number of slots, and for this reason, the SRS periods need to be represented by absolute time, and referring to table 3 below, in the case that table 3 gives different SCS configurations, the absolute times corresponding to a plurality of SRS periods (e.g. SI80 to SI 2560) are respectively:
TABLE 3
Wherein, Δ f represents SCS,indicating the number of slots included in one subframe. Wherein one subframe is 1ms.
In this embodiment, the network device may configure the first SRS period for the dormant BWP in any one of the following manners.
● In a first mode
The first SRS period is selected from a first SRS period set, and the first SRS period set is the first SCS set or an SRS period set corresponding to each SCS in the first SCS set.
Specifically, the network device determines the first SCS set or a first SRS period set corresponding to each SCS in the first SCS set, and selects the first SRS period from the first SRS period set. Here, in an alternative, the first set of SRS periods is determined based on a protocol.
In an optional manner, the protocol specifies a first SRS period set corresponding to the first SCS set, and when configuring the SRS period for the terminal device, the network device selects an appropriate SRS period from the first SRS period set for configuration. For example: the network device selects an SRS period from the first set of SRS periods that is greater than or equal to a first absolute time threshold. Here, the first absolute time threshold is, for example, 100ms.
In another optional manner, the protocol specifies an SRS period set corresponding to each SCS in the first SCS set, the SRS period sets corresponding to all SCS form the first SRS period set, and the network device selects a suitable SRS period from the first SRS period set for configuration when configuring the SRS period for the terminal device. For example: the network device selects an SRS period from the first set of SRS periods that is greater than or equal to a first absolute time threshold. Here, the first absolute time threshold is, for example, 100ms.
● Mode two
The first SRS period is selected from a second SRS period set, and the second SRS period set is an SRS period set corresponding to SCS configured by the dormant BWP.
Specifically, the network device determines a second SRS period set corresponding to the SCS configured by the dormant BWP, and selects the first SRS period from the second SRS period set.
Here, the second set of SRS periods includes one or more SRS periods supported by SCS of the dormant BWP configuration.
In an optional manner, the protocol specifies an SRS period set corresponding to each SCS in the first SCS set, and when the network device configures an SRS period for the terminal device, according to an SCS configured by the dormant BWP, the network device selects a suitable SRS period from the second SRS period set corresponding to the SCS for configuration. For example: the network device selects an SRS period from the second set of SRS periods that is greater than or equal to the first absolute time threshold. Here, the first absolute time threshold is, for example, 100ms.
● Mode III
If the dormant BWP belongs to a first Frequency Range (Frequency Range 1, FR1), the first SRS period is selected from a third SRS period set corresponding to the FR 1; or, if the dormant BWP belongs to a second Frequency Range (Frequency Range 2, fr2), the first SRS period is selected from a fourth SRS period set corresponding to the FR2.
Specifically, the network device determines whether the dormant BWP belongs to FR1 or FR2; a) If the dormant BWP belongs to FR1, the network device selects the first SRS period from a third SRS period set corresponding to the FR 1; or, B) if the dormant BWP belongs to FR2, the network device selects the first SRS period from a fourth SRS period set corresponding to the FR2. Here, in an alternative, the third set of SRS periods and the fourth set of SRS periods are determined based on a protocol.
In an alternative, the protocol specifies a third set of SRS periods for FR1 and a fourth set of SRS periods for FR2. For example: the third SRS period set corresponding to FR1 includes: { sl320, sl640, sl1280, sl2560}, the fourth set of SRS periods for FR2 includes: { sl1280, sl2560}.
The network device determines whether the FR to which the dormant BWP belongs is FR1 or FR2. If the FR to which the dormant BWP belongs is FR1, an appropriate SRS period is selected from the third SRS period set corresponding to FR1 and configured. For example: the network device selects an SRS period from the third set of SRS periods that is greater than or equal to the first absolute time threshold. If the FR to which the dormant BWP belongs is FR2, an appropriate SRS period is selected from the fourth SRS period set corresponding to FR2 and configured. For example: the network device selects an SRS period from the fourth set of SRS periods that is greater than or equal to the first absolute time threshold. Here, the first absolute time threshold is, for example, 100ms.
In the above scheme, the frequency ranges of FR1 and FR2 are shown in table 4 below:
frequency range | |
FR1 | 410MHz–7125MHz |
FR2 | 24250MHz–52600MHz |
TABLE 4
● Mode IV
The network device determines the first SRS cycle based on a first absolute time threshold, wherein an absolute duration of the first SRS cycle is greater than or equal to the first absolute time threshold. Here, in an alternative, the first absolute time threshold is determined based on a protocol.
In one example, the first absolute time threshold is 100ms. It should be noted that the first absolute time threshold may also be other absolute time values greater than 100ms or less than 100ms.
It should be noted that, in the first to fourth manners, the network device is constrained to configure the first SRS period for the dormant BWP, where in the first to third manners, the network device is constrained to configure the first SRS period through a specific SRS period set, and in the fourth manner, the network device is constrained to configure the first SRS period through a first absolute time threshold.
The first to fourth embodiments may be implemented individually, or the fourth embodiment may be implemented in combination with the first, second, or third embodiment.
In this embodiment, the terminal device may also report some configuration information expected by itself, referred to as auxiliary information, to the network device according to the activation delay requirement and the energy saving requirement of the terminal device for the SCell. In an alternative, the auxiliary information includes at least one of: the SRS period expected by the terminal equipment, the comb information of the SRS frequency domain expected by the terminal equipment, the bandwidth of the dormant BWP expected by the terminal equipment and the SCS of the dormant BWP expected by the terminal equipment.
Specifically, the terminal device sends the auxiliary information to the network device. Correspondingly, the network device receives the auxiliary information sent by the terminal device, and determines the SRS configuration and/or BWP configuration of the dormant BWP based on the auxiliary information.
According to the technical scheme of the embodiment of the application, the scheme of restricting the SRS period configuration in the dormant BWP is provided, so that SRS transmission is supported on the dormant BWP, and the configured SRS period can meet the purpose of power saving of terminal equipment.
