Abstract

The invention provides a side link CSI (Channel State Information) reporting control method, a side link CSI reporting method and related equipment, the side link CSI reporting control method comprises the following steps: sending a PC5 radio resource control RRC (Radio Resource Control) message to a side link transmission receiving end, the PC5 radio resource control RRC message carrying side link CSI configuration information; and receiving a target CSI reported by the receiving end based on the side link CSI configuration information. According to the embodiment of the invention, the side link supports CSI reporting, so that selection can be carried out according to the actual link condition when the sending parameter is selected, and the resource overhead is reduced on the basis of improving the sending success rate. According to the embodiment of the invention, the transmission efficiency of side link transmission is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a sidelink channel state information (Channel State Information), a CSI reporting control method, a sidelink CSI reporting method and related equipment. Background technique [0002] In traditional V2X sidelink (sidelink) transmission, since the broadcast service is the mainstay and lacks the support of PC5 radio resource control (Radio Resource Control, RRC) signaling, CSI cannot be reported. As a result, the link state information cannot be obtained, and the transmission parameters cannot be selected according to the actual link conditions, which is prone to resource waste or transmission failure, thus making the transmission efficiency of the side link transmission low. Contents of the invention [0003] Embodiments of the present invention provide a sidelink CSI reporting control method, a sidelink CSI reporting method and related equipment, so as to solve th...
