Description
Technical field
The present invention relates to wireless communication system technologies, in particular to the transmission method and equipment of a kind of signal.
Background technique
Transmission in wireless communication system includes: by the biography of base station (gNB) to user equipment (UE, User Equipment)
Defeated (referred to as downlink transfer), corresponding time slot are known as descending time slot, by the transmission (referred to as uplink) of UE to base station, accordingly
Time slot is known as ascending time slot.
In the downlink communication of wireless communication system, pass through hybrid automatic repeat-request (HARQ, Hybrid Automatic
Repeat reQuest) technology ensures the received reliability of downlink data.The data of downlink are that base station is shared by downlink physical
Channel (PDSCH, Physical Downlink Shared Channel) is transferred to UE, and UE is asked by transmitting mixed automatic retransfer
Response (HARQ-ACK, Hybrid Automatic Repeat request-Acknowledgement) feedback information is asked to tell
Whether base station, the UE are received correctly PDSCH, HARQ-ACK information be UE by Physical Uplink Control Channel (PUCCH,
Physical Uplink Control Channel) it is transferred to base station.
For each of the PDSCH that receives transmission block (Transmission Block, TB), or the finger received
Show downlink physical control channel (PDCCH, the Physical of SPS (Semi-Persistent Scheduling) release
Downlink Control Channel) (being referred to as downlink HARQ transmission for both above-mentioned below), UE needs to pass through on corresponding
Row subframe (is properly received) bit or NACK (for garbled-reception or loss) bit, hereafter referred to collectively as HARQ- to base station feedback ACK
ACK bit will retransmit the corresponding transmission block of NACK or indicate the PDCCH of SPS release if gNB receives NACK bit.
In new wireless (NR, New Radio) communication system, before wireless heterogeneous networks foundation, such as random access
When in the process, the performance of random access directly influences the experience of user.Traditional wireless communication system, such as LTE and LTE-
In Advanced, random access procedure is applied to as established initial link, cell switching, re-establishing uplink, RRC company
Multiple scenes such as reconstruction are connect, and are divided into random access competition-based according to the whether exclusive leader sequence resources of user
(Contention-based Random Access) and based on non-competing random access (Contention-free
Random Access).Due in random access competition-based, each user during attempting to establish uplink, from
Leader sequence is selected in identical leader sequence resources, it is possible that multiple users select identical leader sequence to be sent to base
It stands, therefore Conflicts management strategy is the important research direction in random access, how to reduce collision probability, how quickly to solve
Conflict through occurring is the key index for influencing random access performance.
Random access procedure competition-based is divided into four steps in LTE-A, as shown in Figure 2.In the first step, user is from leading sequence
A leader sequence is randomly choosed in column resource pool, is sent to base station.Base station carries out correlation detection to signal is received, to know
It Chu not leader sequence transmitted by user；In second step, base station sends random access response (Random Access to user
Response, RAR), comprising random access leader sequence identifier, according to timing determined by time delay estimation between user and base station
Instruction, Temporary Cell Radio Network temporary identifier (Cell-Radio Network Temporary Identifier, C- in advance
RNTI), and by user's running time-frequency resource that next time, uplink distributed；In third step, user according to the information in RAR, to
Base station sends Article 3 message (Msg3).It include the information such as user terminal identification and RRC linking request in Msg3, wherein should
User terminal identification is that user is unique, for solving conflict；In 4th step, base station sends Conflict solving mark, packet to user
The user terminal identification of the user to win in Conflict solving is contained.User is after the mark for detecting oneself, by interim C-RNTI
Upgrade to C-RNTI, and send ack signal to base station, completes random access procedure, and wait the scheduling of base station.Otherwise, user
It will start new random access procedure after one section of delay.
For that since base station known users identify, can be distributed for user leading based on non-competing random access procedure
Sequence.Therefore when user leads sequence before sending, random selection sequence is not needed, and will use the leader sequence distributed.Base
It stands after detecting the leader sequence distributed, corresponding random access response, including timing advance and ascending resource can be sent
The information such as distribution.After user receives random access response, it is believed that uplink synchronous is completed, waits the further scheduling of base station.
Therefore, only include two steps based on non-competing random access procedure: step 1 is to send leader sequence；Step 2 is random
Access the transmission of response.
Random access procedure in LTE is suitable for following scene:
Initial access under 1.RRC_IDLE；
2. re-establishing RRC connection；
3. cell switches；
Downlink data reaches and requests random access procedure under 4.RRC connected state (when uplink is in asynchronous)；
Upstream data reaches and requests random access procedure (when uplink is in asynchronous or PUCCH under 5.RRC connected state
Resource is not distributed to scheduling request in resource)；
6. positioning.
In LTE, above-mentioned six kinds of scenes use identical random access step.
When UE transmits HARQ-ACK feedback information by PUCCH, UE is it is to be understood that transmit the PUCCH resource of HARQ-ACK.
But before UE is in RRC link, when system is using simplifying PDCCH format and coming dispatching uplink resource or downlink resource,
