Description

A kind of determination method of running time-frequency resource, configuration method and equipment

Technical field

The present invention relates to wireless communication technology fields, more particularly, to a kind of determination method of running time-frequency resource, configuration side Method and equipment.

Background technique

With the fast development of information industry, especially from mobile Internet and Internet of Things (IoT, internet of Things increased requirement) brings unprecedented challenge to future mobile.Such as according to International Telecommunication Union ITU Report ITU-R M. [IMT.BEYOND 2020.TRAFFIC], it is contemplated that arrive the year two thousand twenty, mobile service amount increases opposite (the 4G epoch) in 2010 will increase nearly 1000 times, and user equipment connection number also will be more than 17,000,000,000, with magnanimity IoT equipment by Mobile communications network is gradually penetrated into, connection number of devices will be more surprising.In order to cope with this unprecedented challenge, communications industry circle Extensive 5th third-generation mobile communication technical research (5G) is expanded with academia, towards the year two thousand twenty generation.At present in the report of ITU Accuse ITU-R M. [IMT.VISION] in discuss future 5G frame and overall goals, wherein the demand to 5G look forward to, Application scenarios and every important performance indexes elaborate.For the new demand in 5G, the report ITU-R M. of ITU [IMT.FUTURE TECHNOLOGY TRENDS] provides the relevant information of technological trend for 5G, it is intended to which solution system gulps down The amount of spitting is obviously improved, user experience consistency, scalability are to support IoT, time delay, efficiency, cost, network flexibility, new industrial The prominent questions such as the support of business and flexible spectrum utilization.

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, system passes through synchronization signal block (SSB, synchronization Signal/PBCH block) synchronization signal and period of broadcast channel be sent to user, which is synchronization signal block week Phase (SSB periodicity, SSB period), or referred to as synchronization signal block group period (SSB burst periodicity). Meanwhile base station can configure a random access configuration period (Physical random access channel Configuration period, PRACH configuration period), it is configured within this period a certain number of random It accesses transmission opportunity (PRACH transmission occasion, RO), and meets in mapping period (mapping Period or association period) all SSB can be mapped on corresponding RO in (regular hour length).

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 1.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.In new system design, in base station to UE When sending dispatching downlink or uplink license, UE is by the existing downlink control for obtaining scheduling random access response on a control channel Information contains the time-frequency location configuration information of the downlink or uplink resource for scheduling in obtained Downlink Control Information, should Configuration information is to have obtained all possible time-frequency location configuration of system configuration based on UE to indicate.But for first Begin the user of access, does not get all possible time-frequency location configuration of system configuration, it is therefore desirable to a kind of default Configuration is at least used for the transmission of system information, and for random access user to collect random access response or Conflict solving When message, be limited to the size of frequency domain resource, it may occur that accidental access response message or contention resolution message be Therefore how system message collision configures and determines that the response message etc. in random access is problem to be solved.
