Problems solved by technology

In SL, both parties to the communication are terminal devices, and their serving base stations may be different, and their status of base station coverage or non-base station coverage is also uncertain.
[0003] At present, there is no specific solution for channel measurement in sidelink (SL) scenarios such as V2X

Embodiment Construction

[0082] The technical solution in this application will be described below with reference to the accompanying drawings.

[0083] The technical solution of the present application can be applied in fields such as vehicle-to-everything (V2X), intelligent networked vehicles, automatic driving or assisted driving, and the like.

[0084] see figure 1 , figure 1 It is a schematic diagram of a V2X communication scenario. In V2X communication, the link between vehicle user equipment (vehicle-user equipment, V-UE) and vehicle user equipment, pedestrian user equipment and vehicle user equipment, roadside unit (roadside unit, RSU) equipment is called sidelink link (sidelink, SL). The link between vehicle user equipment and network equipment is called downlink (downlink, DL) or uplink (uplink, UL), and its air interface is also called Uu air interface, and the corresponding DL communication and UL communication are also called Uu communication.

[0085] It should be understood that bo...

Abstract

The invention provides a method and a device for channel measurement. The method and the device can be applied to the fields of Internet of Vehicles V2X, intelligent networked automobiles, automatic driving or unmanned driving and the like. In a channel reporting process of a sidelink, a sending end device of sidelink communication indicates one or more candidate time intervals to a receiving enddevice, and the receiving end device can try to acquire available PSSCH for sending a channel measurement report in time domain resources corresponding to the one or more candidate time intervals. A feasible scheme is provided for channel measurement of the sidelink.

Description

technical field [0001] The present application relates to the field of Internet of Vehicles, and more specifically, to a sidelink channel measurement method and a terminal device. Background technique [0002] In the evolution of communication systems, the requirements for channel state information (CSI) of various generations of communication systems have not changed. At the signal transmitting end, channel state information (CSI) is used to calculate appropriate transmission parameters to optimize the efficiency of wireless channel usage. At the signal receiving end, CSI is used to achieve correct signal reception. In a new radio (new radio, NR) system, the channel measurement process has tended to be perfect. In the downlink and uplink, it is implemented through flexible channel state information reference signal (channel state information reference signal, CSI-RS) framework and sounding reference signal (sounding reference signal, SRS) framework respectively. However,...
