Description

Random access resource instruction, accidental access method, base station, terminal and device

Technical field

The present invention relates to field of communication technology, a kind of random access resource instruction, accidental access method, base are referred in particular to It stands, terminal and device.

Background technique

The random access of LTE (long term evolution) system is used for five purposes: terminal initial access；RRC(Radio Resource Control, wireless heterogeneous networks) connection reconstruction；Switching；Downlink data arrives when RRC connected state under asynchronous regime It reaches；Upstream data reaches when RRC connected state；Positioning when RRC connected state.NR (newly eat dishes without rice or wine) system also introduce system message request (SI request), Idle state terminal restore the mesh such as connection, wave beam failure recovery (BFR, Beam Failure Recovery) 's.

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

Random access procedure is competed as shown in Figure 1, being broadly divided into four steps:

Message 1 (Msg1): terminal selects random access code preamble (random access lead code) and random access resource PRACH (Physical Random Access Channel, Physical Random Access Channel), in the PRACH resource of selection to Base station sends selected random access code preamble.In NR, " Msg1based SI is requested for the system message based on Msg1 Request " reserves specific preamble and/or PRACH resource.

Message 2 (Msg2): base station receives random access request Msg1, sends random access response to terminal, connects at random Enter in response and faces comprising what uplink timing advance, ascending resource UL grant for (message 3) Msg3 distribution, network side distributed When C-RNTI (Cell Radio Network Temporary Identifier, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI).Carrying The PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) of Msg2 scheduling message uses RA- RNTI (mark user sends out resource block used in random access preamble) is scrambled, and preamble ID is also carried in Msg2, and terminal is logical Crossing RA-RNTI and preamble ID, to determine that the Msg2 is corresponding with the Msg1 that it sends.In NR, for based on Msg1's System message is requested, and the corresponding preamble id information of Msg1 is only contained in Msg2, without other content.And for base Scene is requested in the system message of Msg1, random access procedure to Msg2 just finishes, i.e., if including in the Msg2 received Preamble ID corresponding with the preamble that Msg1 is sent, then it is assumed that the system message request process based on Msg1 is completed.

Message 3 (Msg3): terminal sends uplink on the UL grant that Msg2 is specified, and different random accesses reason The content of Msg3 uplink is different, for example is initially accessed, and Msg3 transmission is that request is established in RRC connection.

Message 4 (Msg4): contention resolution message, terminal may determine that whether random access succeeds according to Msg4.For first Beginning access terminal, interim C-RNTI is automatically converted to terminal and identifies C- in the unique end of the cell after contention resolved success RNTI。

Non-competing random access procedure is as shown in Fig. 2, be broadly divided into three steps:

Message 0 (Msg0): base station connects for the dedicated preamble of non-competing random access and at random to terminal distribution Enter the PRACH resource used.Non-competing random access private resource be by RRC signaling (such as switching or SCG When (Secondary Cell Group, secondary cell group) is added) or physical layer signaling PDCCH distribution.

Message 1 (Msg1): terminal is sent in specified PRACH resource to base station specified special according to the instruction of Msg0 Use preamble.Base station receives and calculates uplink timing advance TA according to Msg1 after Msg1.

Message 2 (Msg2): base station sends random access response to terminal, believes in random access response comprising Timing Advance Breath, subsequent upstream transmission resource allocation UL grant, Timing Advance are used for the timing relationship of SS later uplink.

Wave beam management is introduced in NR system, terminal needs to select according to channel situation reasonable when initiating random access Random access resource.Several typical cases are for example: 1) cell include a descending carrier and two up-link carriers (UL and SUL, Uplink and supplementary Uplink) when, terminal is measured according to descending carrier, if down channel quality is higher than Thresholding selects UL to initiate random access, if channel quality is lower than thresholding, SUL is selected to initiate random access；2) beam selection (also referred to as synchronization signal block SS block/ channel state information reference signals CSI-RS selection): if terminal be assigned it is non-competing Random access resource, measures the channel quality of the corresponding down direction SS block or CSI-RS of the resource, and selection is greater than thresholding The corresponding physical layer random access resource (PRACH) of SS block or CSI-RS initiate random access, if not meeting door The non-competing random access resource of limit condition, then measure other SS block or CSI-RS, and selection meets channel quality thresholds item The corresponding PRACH of the SS block/CSI-RS of part initiates competition random access；3) it wave beam failure recovery BFR: is used to terminal base station RRC signaling distributes non-competing random access resource and initiates random access, if do not meet channel threshold condition it is non-competing with Machine access-in resource, then measure other SS block/CSI-RS, and selection meets the SS block/CSI- of channel quality thresholds condition The corresponding PRACH resource of RS initiates competition random access.

In new generation of wireless communication system (NR system, 5G system), multiple resources dimension is introduced, including a cell carries In wave, multiple portions bandwidth BW P (BandWidth Part) is configured for terminal；It, can be there are two up-link carrier in one cell UL and SUL；Carrier wave polymerize under CA, and terminal can work in the cell of multiple member carriers composition simultaneously.With a cell The introducing of multiple up-link carriers and wave beam management when non-competing to the terminal distribution random access resource in base station, needs to consider not With giving terminal to configure random access resource respectively on beam direction or different up-link carrier.The prior art can not achieve and meanwhile to Terminal distributes non-competing random access resource on different up-link carriers or different beams.For example, being distributed with PDCCH order non-competing When striving random access resource, a PRACH resource can only be once distributed, next PDCCH order is considered as new non-competing random Access-in resource distribution, the PRACH resource failed distributed in the past, therefore can not be in different beams or difference based on the prior art Non-competing random access resource is distributed on carrier wave simultaneously.
