Background

The Sidelink UE introduces a carrier aggregation (PC5carrier aggregation, PC5CA) function in the wireless air interface PC5, and the UE can transmit and receive on multiple PC5 carriers, thereby further improving the data throughput. Regarding which candidate PC5 carriers are selected by the UE for CA during data transmission, the selection of the Sidelink UE PC5carrier is controlled by the base station through configuring or pre-configuring appropriate parameters based on the comprehensive consideration of factors such as the UE Radio Frequency (RF) capability, the current Channel congestion rate (CBR), the UE service Priority (PPPP), and the like.

In the R14LTE V2X standard, a network configures or pre-configures multiple transmission resource pools for a Sidelink UE, each resource pool corresponds to one PC5carrier, and accordingly, each resource pool corresponds to a set of CBR-PPPP-data transmission parameter List TxConfig, and the UE dynamically adjusts the data transmission parameter TxConfig based on a current CBR range and PPPP range, where the TxConfig parameter includes a Modulation and Coding Scheme (MCS), a physical resource block number (PRB number), a retransmission number (retransmission number), and the like, where a CBR value range is 0 to 100%, and a PPPP value range is 1 to 8, so that the network can control a situation of using wireless resources on each PC5 carrier. The PC5carrier aggregation is a function introduced by R15, and in the R15 standardization stage, a network reuses the design idea of R14CBR-PPPP-TxConfigList parameters to realize the control of PC5carrier selection, so how to design a reasonable parameter configuration method to realize the control of high-version (R15) UE transmission carrier selection, and meanwhile, the problem that the transmission behavior of low-version (R14) UE is not influenced becomes the problem to be solved.
