Description

The exemplary embodiments of this disclosure relate, as a whole, to the field of communications technology, and more particularly to methods, apparatus, and media for sidelink communications. In 5G NR, sidelink communication is being developed in the unlicensed spectrum (also known as SL-U). SL-U supports both interlaced resource block (RB)-based transmission and continuous RB-based transmission. The frequency domain resource allocation granularity for SL-U is subchannels for the Physical Sidelink Shared Channel (PSSCH). For interlaced RB-based transmission, a subchannel can consist of one or more interlaces. Depending on the specific channel configuration and overhead, subchannels differ in the number of interlaces and the number of physical resource blocks (PRBs) contained within each interlace. For continuous RB-based transmission, subchannel division is independent of the division of resource sets within the resource pool. Therefore, SL-U is expected to offer improvements in resource allocation, transport block size (TBS) determination, and utilization efficiency. The accompanying drawings further illustrate some embodiments of this disclosure in more detail, thereby further clarifying the aforementioned and other objectives, features, and advantages of this disclosure.
