Description

Data transmission method and device
Technical Field
The present invention relates to wireless communication technologies, and in particular, to a data transmission method and apparatus in a Long-Term Evolution (LTE) system.
Background
The fifth generation mobile communication technology (5 g, 5) under investigation in the third generation partnership project (3GPP,the 3rd Generation Partnership Project) th Generation) puts high demands on control plane delay, requiring that User Equipment (UE) can enter a connected state within a time frame of 10ms and start transmitting data. However, in the conventional LTE system, many procedures such as initial random access, connection establishment, registration authentication, etc. are required to go from an idle state to a connected state, which makes it difficult for the UE to enter the connected state within 10 ms. To overcome this problem, 3GPP introduced a new UE state, an inactive (inactive) state. When the UE enters the state from the connected state, the anchor base station (anchor eNB) and the core network to which the user is initially connected maintain all connection configuration and processing uplink of the user all the time, so that the user can directly enter the connected state only after the air interface completes the air interface configuration through a simple random access similar process. Meanwhile, in order to save power, the UE does not configure uplink control channel (PUCCH, physical Uplink Control CHannel) and sounding resources in an inactive state and adopts similar measurement and cell selection strategies as in an idle state. Therefore, the user in the inactive state may lose uplink synchronization during the moving process of the macro cell, that is, the Timing advance (Timing advance) adopted in the uplink transmission may be unusable due to the movement, and the Timing advance measurement must be performed again through random access or similar processes.
Many applications have background traffic in addition to the short-time mass data transmission. The frequency of sending data packets is generally low, and the data packets are relatively small. For these background services, if the UE in the inactive state can support direct data transmission, that is, can transmit a small amount of data without switching to the connected state, signaling overhead and power consumption of the UE can be further saved. Therefore, how to support direct data transmission of inactive state users in an LTE system is a considerable problem.

Detailed Description
For a more complete understanding of the nature and the technical content of the embodiments of the present invention, reference should be made to the following detailed description of embodiments of the invention, taken in conjunction with the accompanying drawings, which are meant to be illustrative only and not limiting of the embodiments of the invention.
In the current 3GPP discussion, the uplink direct data transmission may adopt unlicensed transmission, that is, the base station directly divides a part of radio resources into dedicated uplink small data transmission, where the part of radio resources may be dedicated for allocation to a certain UE or may be allocated to multiple UEs for sharing uplink data transmission; the downlink direct data transmission may employ a mode in which small data is entrained in the paging message.
In some cases, for unauthorized uplink direct data transmission, the base station needs to return a correct Acknowledgement (ACK) message to tell the user that the uplink data has been successfully received. In addition, for some applications, the receiving end may return some data packets immediately after receiving the uplink data of the UE. Therefore, the downlink direct data transmission in the inactive state caused by the uplink is very common. In this case, the base station knows that the UE is within its coverage area since the base station has received the uplink data packet before the downlink data transmission. In this case, some optimized method may be used to transmit the downlink data. The embodiment of the invention mainly discusses how to effectively support downlink direct data transmission caused by uplink data in an inactive state.
Fig. 1 is a flow chart of a data transmission method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step 101: the UE in the inactive state acquires downlink control information (DCI, downlink Control Information) of downlink data from a downlink control channel (PDCCH, physical Downlink Control Channel) using a radio network temporary identity (RNTI, radio Network Tempory Identity).
In an embodiment, the downlink control information carries user status information of the UE.
In an embodiment, the downlink control information carries user status information of the UE, including at least one of the following:
the downlink control information carries information whether the UE is in an inactive state or not;
the downlink control information carries information whether the UE is in a connection state or not.
In an embodiment, the RNTI is specific to a single UE in an inactive state.
Here, the RNTI is at least one of:
the RNTI is a Cell radio network temporary identifier (C-RNTI, cell-Radio Network Tempory Identity) used by the UE in a connection state for the previous time;
the RNTI is all or part of the user identity of the UE in the inactive state.
In an embodiment, the inactive state user identity is allocated by a base station and notified to the UE when the UE enters an inactive state.
In an embodiment, the inactive state user identity includes information of an anchor base station and information of the UE, where the anchor base station is a base station that stores a user context.
In an embodiment, the information of the UE includes at least one of:
the identity stored in the UE, the UE identity allocated by the mobility management function entity (MME, mobility Management Entity), and the C-RNTI used by the UE in the previous connection state.
In the embodiment of the invention, the UE in the inactive state monitors a downlink control channel by using the RNTI within a preset time range.
Here, the UE in the inactive state performs periodic sleep within the preset time range, and listens to the downlink control channel at least one transmission time interval (TTI, transmission Time Interval) after waking up.
Here, the times of sleep and awake are negotiated with an anchor base station through signaling before the UE enters an inactive state.
Step 102: the UE in the inactive state receives a data packet sent by a base station in a downlink shared channel (PDSCH, physical Downlink Shared Channel) according to the downlink control information, wherein the UE remains in the inactive state after receiving the data packet.
According to the technical scheme provided by the embodiment of the invention, the UE in the inactive state directly obtains the DCI of the downlink data from the PDCCH by using the specific RNTI, and then the UE directly receives the data packet sent by the base station in the PDSCH according to the downlink control information and keeps the data packet in the inactive state. Therefore, when the UE in the inactive state receives downlink data, the UE does not need to be frequently switched between the connected state and the inactive state, so that a lot of signaling overhead is saved, and correspondingly, the power consumption of the UE in the inactive state is reduced.
Fig. 2 is a schematic flow chart of uplink data transmission and downlink ACK or data reception by using a dedicated RNTI value for an inactive UE according to an embodiment of the present invention. As shown in fig. 2, the specific implementation process is as follows:
step 201: the UE entering the inactive state monitors unauthorized transmission information transmitted by the base station.
Here, the unauthorized transmission information may include one or more of the following: radio resource location information for unlicensed transmission, adjustment code selection information for unlicensed transmission, uplink power control information for unlicensed transmission, RNTI value information used for downlink response for unlicensed transmission, retransmission waiting time for unlicensed transmission, subsequent PDCCH monitoring time for unlicensed transmission, and the like.
In one embodiment, the unauthorized transmission information may be transmitted through a broadcast channel. For example, the unlicensed transmission information may be transmitted through an inactive UE-specific broadcast channel. The unlicensed transmission information may be signaled to the UE through dedicated radio resource control (RRC, radio Resource Control) before the UE enters an inactive state.
Step 202: and the UE uses the unauthorized resource to send uplink data according to the unauthorized sending information.
Step 203: the base station transmits the new DCI using the RNTI value of the UE.
In an embodiment, the DCI may further include information of a user state. For example: the DCI includes information on whether a user is in an inactive state. For another example, the DCI includes information on whether or not the user is in a connected state.
In an embodiment, the RNTI may be specific to a single inactive state UE.
In an embodiment, the RNTI may be a C-RNTI value used by the UE in a previous connection state.
In an embodiment, the RNTI may be all or part of the inactive state user identity.
Here, the inactive state user id may be assigned by the base station and notified to the user when the user enters the inactive state.
Here, the inactive state user identity may include information of an anchor base station (i.e., a base station that maintains a user context) and information of the UE itself.
Here, the information of the UE itself may include one or more of the following: identity stored in the UE, UE identity allocated by MME, C-RNTI used by the last connection state of the UE, etc.
Step 204: and the user receives the ACK information and/or the subsequent data of the base station according to the DCI and still keeps the inactive state.
Fig. 3 is an example of a dedicated new DCI format including user status information according to an embodiment of the present invention, where 1-bit information is used to represent status information of UE, as shown in fig. 3. For example: the connected state is represented by a bit "0" and the inactive state is represented by a bit "1".
Fig. 4 is a schematic flow chart of uplink data retransmission performed by the UE in the inactive state according to the embodiment of the present invention, as shown in fig. 4, the specific implementation process is as follows:
step 401: the UE entering the inactive state monitors unauthorized transmission information transmitted by the base station.
Here, the unauthorized transmission information may include one or more of the following: radio resource location information for unlicensed transmission, adjustment code selection information for unlicensed transmission, uplink power control information for unlicensed transmission, RNTI value information used for downlink response for unlicensed transmission, retransmission waiting time for unlicensed transmission, subsequent PDCCH monitoring time for unlicensed transmission, and the like.
In one embodiment, the unauthorized transmission information may be transmitted through a broadcast channel. For example, the unlicensed transmission information may be transmitted through an inactive UE-specific broadcast channel. The unlicensed transmission information may be also notified to the UE through dedicated RRC signaling before the UE enters the inactive state.
Step 402: and the UE uses the unauthorized resource to send uplink data according to the unauthorized sending information.
Step 403: and the UE does not receive the ACK and/or the subsequent data of the base station within a certain time range, and retransmits the uplink data by using unauthorized resources according to the unauthorized transmission information.
Here, the time range in step 403 may be retransmission waiting time of unlicensed transmission, subsequent PDCCH listening time of unlicensed transmission, or the like.
Fig. 5 is a signaling interaction flow chart of a UE in a connection state entering an inactive state according to an embodiment of the present invention, as shown in fig. 5, and the specific implementation process is as follows:
step 501: the base station transmits an "inactive state configuration command" message to the UE entering the connected state.
In an embodiment, the "inactive state configuration command" message may be a new RRC signaling message or may be included in an existing RRC signaling message.
In an embodiment, the "inactive state configuration command" message may include a specific sleep and wake time configuration of the UE in an inactive state.
In an embodiment, the "inactive state configuration command" message may include cell selection and reselection information for the UE in an inactive state.
Step 502: the UE sends a 'non-active state configuration confirmation' message to the base station, confirms that the UE will immediately enter the non-active state, and performs relevant actions according to the information in the configuration command message.
