Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a processing method, a communication device and a storage medium. Background Art

[0002] In some implementations, when the number of RB sets (Resource Block sets) used to transmit S-SSB (Sidelink-Synchronization Signal Block) changes, the transmit power of a single RB set transmitting S-SSB will change as the number of RB sets changes. S-SSB can also be called S-SS / PSBCHBlock (Sidelink-Synchronization Signal / Physical Sidelink Broadcast Channel).

[0003] During the process of conceiving and implementing this application, the inventors discovered that when the transmission power of the S-SSB transmitted by the RB set changes with the number of RBsets, it will cause the receiving device to measure the PSBCH-RSRP (Physical SidelinkBroadcast Channel-Reference Signal Receiving Power) of the S-SSB inaccurately, thereby affecting the accuracy of the receiving device's selection of the synchronization source based on the PSBCH-RSRP.
