Embodiment

Inventor notices during invention：

UE (generally connected state UE, it is also possible to inactive for carrying out signaling and data interaction with network side UE), if using the cell-level signaling and the mode of data transfer in LTE (Long Term Evolution, Long Term Evolution), That is UE nonrecognition TRP/Beam, UE and the Signalling exchange of cell need to complete by whole TRP/Beam in cell, specific next Say, the downlink data transmission to UE needs a whole or many TRP/Beam in cell synchronously to send, transmitting uplink data needs All or much a TRP/Beam is synchronously received in cell.This mode one increases interface-free resources expense, reduces power system capacity； Two increase network side and terminal power consumption；Three due to terminal cannot identify TRP/Beam, it is impossible to carry out accurate channel estimation Measurement and accurately power control, are unfavorable for the raising of signaling and data transmission credibility.

The problem of random access procedure is specifically described below and brings is as follows：

The random access of LTE system is divided into two kinds of competition random access and non-competing random access.Its process difference is as follows：

Competition random access is used for six purposes：Terminal initial accesses；RRC (Radio Resource Control, wirelessly Resources control) connection reconstruction；Switching；Downlink data reaches during RRC connected states under asynchronous regime；Upper line number during RRC connected states According to arrival；Positioning during RRC connected states.

Fig. 2 is competition random access procedure schematic diagram, as shown in Fig. 2, being broadly divided into four steps：

Msg1：UE selection random access preamble (random access preamble) and PRACH (Physical Random Access Channel, Physical Random Access Channel) resource and selected random access is sent to base station using the PRACH resources preamble。

Msg2：Base station receives preamble, calculates TA (Time Alignment, Timing Advance), and send to UE Random access response, includes the Timing Advance information and the UL grant (uplink schedulings for Msg3 in random access response Information), and interim C-RNTI (Cell-Radio Network Temporary Identifier, the cell of network side distribution Radio Network Temporary Identifier).Carry Msg2 scheduling messages PDCCH (physical downlink control channel, Physical Downlink Control Channel) with RA-RNTI (Random Access-Radio Network Temporary Identity, with Machine access wireless network identifies temporarily) scramble, RA-RNTI is uniquely corresponding with the running time-frequency resource of transmission Msg1 in 10ms windows；Separately Preamble ID, UE are also carried in outer Msg2 and determines that the Msg2 is sent with it by RA-RNTI and preamble ID Msg1 is corresponding.

Msg3：On Scheduled transmission (scheduled transmission), UE are sent on the UL grant that Msg2 is specified Row transmission, the content of different random access reason Msg3 uplink is different, for example for being initially accessed, Msg3 transmission is Request is established in RRC connections.

Msg4：Contention Resolution (contention resolved) message, UE may determine that random access is according to Msg4 No success.For being initially accessed UE, interim C-RNTI is automatically converted to unique UE marks of the UE in the cell after contention resolved success Know C-RNTI.

Fig. 3 is competition random access procedure schematic diagram, and non-competing random access is for switching, downlink data reaches, positioning With acquisition uplink timing.As shown in Fig. 2, it is broadly divided into three steps：

Msg0：Base station is used to UE distribution for the dedicated preamble and random access of non-competing random access PRACH resources.

Msg1：UE according to the instruction of Msg0, sent in specified PRACH resources to base station specify it is special preamble.Base station receives and calculates uplink timing advance TA according to Msg1 after Msg1.

Msg2：Base station sends random access response to UE, in random access response comprising Timing Advance information, it is follow-up on Row transfer resource distributes UL grant, and Timing Advance is used for the timing relationship of UE subsequent upstream transmissions.

Fig. 4 is MAC RAR form schematic diagrams, as shown in the figure, random access response Packet Data Unit MAC in LTE system RAR PDU(MAC：Media Access Control, medium education；RAR：Random Access Response, at random Access response；PDU：Protocol Data Unit, protocol Data Unit) form is as follows：

Random access response head：RAPID (Random Preamble ID, random access preamble mark) is used to indicate base Stand the ID of received preamble, and E is used to indicate subsequently whether there is another random access response head.UE is identified by RAPID Whether the preamble of oneself transmission is responded, by identifying that (its numerical value passes through transmission to the RA-RNTI scrambled to MAC RAR PDU The running time-frequency resource position of preamble, which calculates, to be obtained) identify the running time-frequency resource position that the preamble is sent.UE combinations RA-RNTI And RAPID, it is the random access response sent for oneself finally to identify the MAC RAR PDU.

Fig. 5 is the instruction head form schematic diagram that retracts, as shown in the figure, BI (Backoff Indication, retract instruction) is used The delay parameter of random access next time is initiated after UE random access failures are indicated.T be used for indicate be subsequently BI or RAPID。

Fig. 6 is accidental access response message form schematic diagram, as shown in the figure, accidental access response message：A left side for it is conventional with Machine access response, the right side are extension random access response

In new generation of wireless communication system, because signaling and data interaction need not be carried out with network side by residing in cell UE only know cell level knowledge, the UE being initially accessed does not have TRP/Beam information, can only by cell level knowledge and resource into Row random access, is received in this way, UE sends Msg1 by all or part of transfer point in cell or wave beam, and can be had by network side Effect identification, the lateral UE of network are also to be sent out in a synchronous manner by TRP/Beam in cell when sending random access response Msg2 Send.Subsequent Msg3, Msg4 is also to be sent by the TRP/Beam methods of synchronization in cell.This mode occupies institute in cell Have or major part TRP/Beam resources.Also, if to solve above-mentioned UE is carrying out signaling and data biography with network side (connected state UE) is it needs to be determined that TRP/Beam information, to reduce resource overhead and realize transmitting, is initially accessed when defeated UE need to obtain TRP/Beam information by certain mode.

In 5G systems, a cell can include multiple TRP/Beam.If passed using the cell-level signaling and data of LTE Defeated mode is, it is necessary to which the TRP/Beam in all or multiple cells carries out UE signaling and data transfer, one kind using the method for synchronization Typical case is that the message in random access procedure needs synchronously to be sent and received by the TRP/Beam in cell.In this way, one Increase interface-free resources expense, reduce power system capacity；Two increase network side and terminal power consumption；Three cannot be identified due to terminal TRP/Beam, it is impossible to carry out the measurement of accurate channel estimation and accurately power control, be unfavorable for signaling and data transmission credibility Improve.Therefore, UE needs to identify TRP/Beam when needing to carry out signaling and data transfer with network side, to reduce money Source expense, increases power system capacity, improves transmission reliability.

Based on this, in scheme provided in an embodiment of the present invention, in the random access procedure, by random access response to Terminal provides specific transmission unit information in cell, such as the information of TRP/Beam, terminal in subsequent transmission according to the information into Row TRP/Beam is identified and TRP/Beam grades of transmission.The embodiment of the present invention is illustrated below in conjunction with the accompanying drawings.

In declarative procedure, it will be illustrated respectively from the implementation of terminal and network side, wherein network side will illustrate to indicate The process of TRP/Beam, end side will illustrate identification TRP/Beam and random access, the process of transmission, then will also provide two The implementation for the scheme that the example that person's cooperation is implemented is provided with more fully understanding in the embodiment of the present invention.Such explanation mode is not Mean that the two must coordinate implementation or must individually implement, in fact, when terminal and network side are performed separately, its Each solve the problems, such as end side, network side, and during the two combined use, superior technique effect can be obtained.

Step 801, in the random access procedure, terminal receiving random access response, the random access response carries The transfer point of signaling and/or data transfer or the information of wave beam are provided the terminal with cell；

Step 802, according to the random access response determine the transfer point or wave beam；

Step 803, terminal carry out TRP/Beam grades of transmission according to the transfer point or wave beam.

In implementation, for TRP and beam, in existing standard discussion, increasingly tend to only discuss the trend of beam, but It is that either transfer point or wave beam in implementation, or even transfer point are combined with wave beam, and no matter which kind of mode does not affect the application side The implementation of case because the purpose of the scheme of the application in enable the terminal in subsequent transmission according to the information carry out TRP/ Beam is identified and TRP/Beam grades of transmission, and influence is had no as specific transmission mode.

The concrete mode involved in implementation is illustrated below.For simplicity, by transfer point or ripple in implementing to illustrate Beam is referred to as TRP/Beam.

Mode one：The transfer point or wave beam of signaling and/or data transfer are provided the terminal with implementation, in cell, is to receive The transfer point for the Msg1 that terminal is sent or the corresponding uplink and downlink wave beam pair of uplink beam with receiving Msg1.

Wherein, on wave beam, wave beam is directive that uplink and downlink wave beam forms a wave beam pair, carries respectively in force For downstream transmission, it is by uplink beam that network side, which receives Msg1, sends random access response and passes through downlink wave beam.Connect at random Enter instruction or uplink beam or downlink wave beam (the beam information master that the message in response can be uplink and downlink wave beam pair If beam ID), how this uses below if being also depended on.

Specifically, TRP/Beam information sends the information of the corresponding TRP/Beam of Msg1 (preamble) for UE, gNB is at this After receiving Msg1 on TRP/Beam, by its information tissue into the random access response to the UE, be sent to the UE its His information, such as uplink timing advance TA, ascending resource distribution UL grant etc. organize together transmission.UE is receiving the letter After breath, follow-up random access procedure and follow-up data transfer can be carried out on the TRP/Beam that random access response indicates, Namely TRP/Beam grades of transmission are carried out, when specific TRP/Beam grades of progress is transmitted, transmitted in transfer point TRP or in some wave beam Transmission, follows the configured transmission and characteristic of correspondence TRP or beam in transmission.
