Background technique

The Long Term Evolution (LTE) system supports sidelink (sidelink, or translated as side link, side link, side link, etc.) transmission, that is, the terminal (also known as User Equipment (UE)) Data transmission is performed directly on the physical layer. LTE sidelink communicates based on broadcast. Although it can be used to support basic security communications of vehicle to everything (V2X), it is not suitable for other more advanced V2X services. The fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) New Radio (NR) system will support more advanced sidelink transmission design, such as unicast, multicast or multicast, etc., thus supporting more comprehensive business type.

Due to the lack of low-frequency resources, 5G NR uses high-frequency bands such as millimeter waves, such as Frequency Range 2 (FR2). Since the propagation loss of high-frequency bands is larger than that of low-frequency bands, its coverage distance is worse than that of LTE. To this end, 5G NR uses multi-antenna beam forming to enhance the signal, thereby enhancing coverage. Currently, beamforming is a signal processing technique that uses an array of sensors to send and receive signals in a direction. Beamforming technology adjusts the parameters of the basic units of the phase array so that signals at certain angles obtain constructive interference, while signals at other angles obtain destructive interference, so that the antenna beam points in a specific direction.

In the Sidelink high-frequency band, it has not yet been defined how the receiving end determines the receiving beam to perform beam adjustment and data transmission.
