Abstract (en)

A method can include determining a resource allocation framework for sidelink communication, allocating resources in a resource grid for PSCCH, PSSCH, or PSFCH based on the framework, and transmitting at least one sub-channel index and at least one RB set index to indicate resource allocation information of PSCCH, PSSCH, or PSFCH over an SL-U spectrum, wherein the resource allocation framework comprising at least one SL-U CC including an SL-U BWP including X indexed RBs, the SL-U BWP being divided into Y indexed RPs and at least one inter-RP GB when Y being an integer greater than 1, each RP being divided into N indexed RB sets and at least one intra-cell GB when N being an integer greater than 1, K indexed interlaces configured to map the RBs cyclically per BWP, and sub-channels configured to map the interlaces per RB set and cyclically across different RB set per RP.
