Detailed ways

For ease of understanding, the technical terms involved in the embodiments of this disclosure are first introduced:

Channel congestion rate (channel busy ratio, CBR): Indicates that within a preset measurement period (such as 100ms), the sidelink-received signal strength indicator (S-RSSI) exceeds the preconfigured critical value The ratio of the number of subchannels to the total number of subchannels. CBR is an indicator to measure the degree of interference. The larger the CBR, the busier the channel, the greater the system load, and the stronger the interference between different terminals. If the S-RSSI of a certain sub-channel is greater than the preconfigured threshold, it indicates that the sub-channel is occupied. If the S-RSSI of a certain sub-channel is less than or equal to the pre-configured threshold, it indicates that the sub-channel is not occupied. occupied. CBR measurement methods are different, and the obtained CBR can represent different types of channel busyness. For example, within the preset measurement period of 100ms, if the first terminal responds to PSFCH (Physical Sidelink Feedback control Channel), PSSCH (Physical Sidelink Shared Channel) and PSCCH (Physical Sidelink Shared Channel) CBR measurement is performed on three channels: Control Channel (side link control channel). At this time, the obtained CBR represents the overall channel busyness of PSFCH, PSSCH and PSCCH within the preset measurement period; if the first terminal performs CBR measurement on the PSFCH channel CBR measurement, the CBR obtained at this time indicates the busyness of the PSFCH channel within the preset measurement period; if the first terminal performs CBR measurement on both PSSCH and PSCCH channels, the CBR obtained at this time indicates the busyness of the PSFCH channel within the preset measurement period. , the overall channel busyness of PSSCH and PSCCH.

Wherein, if the RSRP of the secondary sidelink link between the first terminal and the second terminal is greater than a preset value (for example, it can be the aforementioned -97db), it is determined to perform sidelink communication with the second terminal through the secondary sidelink link.
