Description

Method and device for wireless communication of secondary link

Technical Field

The present application relates to methods and apparatus in wireless communication systems, and more particularly, to methods and apparatus for supporting channel measurement feedback in sidelink wireless communication.

Background

Channel measurement feedback is a common method in cellular communication, and a receiving user obtains Channel State Information (CSI) by measuring Reference Signal (RS) resources and reports the CSI to a sending user, so that data sending can be more accurately adapted to a Channel state, and the data transmission success rate and the wireless resource utilization rate are improved.

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 various application scenarios, research on NR (New Radio over the air) technology (or fine Generation, 5G) is decided over 72 sessions of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network), and standardization of NR is started over WI (Work Item) that has passed NR over 3GPP RAN #75 sessions. For the rapidly evolving V2X (Vehicle-to-event) service, the 3GPP also started to initiate standards formulation and research work under the NR framework, deciding on standardization of NR V2X DRX start WI over 3GPP RAN #83 fulcrums. Unlike LTE V2X which is dominated by broadcast services, NR V2X introduces unicast and multicast services in addition to broadcast services to support richer application scenarios.

Disclosure of Invention

The inventor finds that Channel measurement feedback is introduced in the unicast transmission of NR V2X, a Tx UE (User Equipment) sends a CSI-RS (Channel State Information-Reference Signal) in a psch (Physical Sidelink Shared Channel), the measurement of the receiving UE on the CSI-RS is used for calculating CSI of the SL, and the CSI is fed back to the sending UE, so that the Tx UE acquires CSI on the SL (Sidelink). Because the channel measurement report is sometimes limited, the Rx UE needs to feed back the channel measurement report within one delay bound (latency bound). In a mode of mode 1 resource allocation of a PC-5 port, Rx UE requests a base station to schedule time-frequency resources for feeding back a channel measurement report, if Rx UE only configures one Scheduling Request (SR) resource set for CSI modes with different delay boundaries, on one hand, if the configured time period of SR is less than the minimum delay boundary, SR resource waste is caused when Rx UE sends CSI with a larger delay boundary; on the other hand, if the time period of the SR configuration is greater than the minimum delay bound, the CSI feedback with the minimum delay bound cannot be satisfied. Meanwhile, the base station cannot judge the delay boundary of the CSI used for transmission of the time-frequency resource requested to be scheduled according to the received SR, and the probability that the time-frequency resource scheduled by the base station exceeds the feedback delay boundary in time is increased, so that the fed-back channel measurement report is overdue, cannot reflect the channel state of the secondary link, and cannot be used by Tx UE to improve the transmission efficiency.

In view of the above, the present application discloses a solution. It should be noted that, in the description of the present application, only the NR V2X scenario is taken as a typical application scenario or example; the application is also applicable to other scenarios (such as relay networks, D2D (Device-to-Device) networks, cellular networks, scenarios supporting half-duplex user equipment) besides NR V2X, which face similar problems, and can also achieve technical effects similar to those in NR V2X scenarios. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to NR V2X scenarios, downstream communication scenarios, etc.) also helps to reduce hardware complexity and cost.
