Description

Method and apparatus in a node used for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus for feedback information in wireless communication.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of multiple application scenarios, research on new air interface technology (NR) or Fifth Generation, 5G) is decided on 3GPP (3rd Generation partner Project) RAN (Radio Access Network) #72 bunions, and work on NR is started on WI (work item) that has passed NR on 3GPP RAN #75 bunions.

The 3GPP has also started to initiate standards development and research work under the NR framework for the rapidly evolving Vehicle-to-evolution (V2X) service. The 3GPP has completed the work of making the requirements for the 5G V2X service and has written the standard TS 22.886. The 3GPP identified and defined a 4 major Use Case Group (Use Case Group) for the 5G V2X service, including: automatic queuing Driving (Vehicles platform), Extended sensing (Extended Sensors), semi/full automatic Driving (Advanced Driving) and Remote Driving (Remote Driving). The 3gpp ran #80 complete pass through the technical research work project (SI, StudyItem) of NRV 2X. The WI (WorkItem) was started for NRV2X at 3GPPRAN #83 subcontracts.

Disclosure of Invention

Compared with the existing LTEV2X system, one significant feature of NRV2X is that multicast and unicast can be supported and HARQ (Hybrid Automatic Repeat Request) function can be supported. The 3gpp ran1#95 conference agreed to introduce a separate feedback channel (PSFCH) for the companion link (Sidelink). The PSFCH is used to carry HARQ (Hybrid Automatic Repeat Request) process. In addition, 3GPP has agreed that User Equipment (UE) can report HARQ feedback accompanying a link (Sidelink) to a base station. To ensure robustness of the companion link transmission, LTEV2X supports retransmission of the companion link. The requirement for robustness of the companion link transmission in NRV2X is even higher than that of LTEV2X, and thus repeated transmission is necessary.

The present application discloses a solution to the problem of duplicate transmissions with links in NRV 2X. It should be noted that, in the description of the present application, only the NRV2X scenario is taken as a typical application scenario or example; the application is also applicable to other scenes than NRV2X facing similar problems, and can also achieve technical effects similar to those in NRV2X scenes. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to the NRV2X scenario and the scenario with link transmission) also helps to reduce hardware complexity and cost. Without conflict, embodiments and features of embodiments in a first node device of the present application may apply to a second node device and vice versa.
