Abstract
Official abstract text for this publication.
There is provided a method of determining PSSCH feedback resources performed at a UE, wherein the PSSCH feedback (PSFCH) resource has a periodicity N defined as a number of slots. The method comprises counting a number of sub-channels, C, of PSSCH in the period N, wherein each sub-channel, c, is associated with a PSFCH resource; counting a number of PSFCH resources, R, in the period N; indexing the sub-channels, c, based on time; and after indexing the sub-channels, c, based on time, indexing the sub-channels, c, based on frequency.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of determining physical sidelink shared channel (PSSCH) feedback resources performed at a UE, wherein the PSSCH feedback (PSFCH) resource has a periodicity N defined as a number of slots, the method comprising: counting a number of sub-channels, C, of PSSCH in the period N, wherein each sub-channel, c, is associated with a PSFCH resource; counting a number of PSFCH resources, R, in the period N; indexing the sub-channels, c, based on time; and after indexing the sub-channels, c, based on time, indexing the sub-channels, c, based on frequency; conveying ACK and NACK feedback of a PSSCH shared channel transmission using two cyclically shifted sequences per transmission, wherein the two cyclically shifted sequences include a first phase shift and a second phase shift, and the second phase shift is 180 degrees from the first phase shift, wherein the PSFCH resource associated with each sub-channel is determined based on a lowest numbered sub-channel of the shared channel transmission. 2 . The method of claim 1 , wherein a PSFCH time-frequency resource for PSSCH sub-channel number c=c modulo-division R.
