Abstract
In an example, a UE receives, from a network, a configuration of a sidelink resource pool. Physical Sidelink Feedback Channel (PSFCH) resources of the sidelink resource pool are configured, periodically with a period of N slots, in slots of the sidelink resource pool. The UE receives, from the network, a configuration with a set of time offsets for determining an association set. The UE determines one or more slots. Each slot of the one or more slots is in the association set and contains a PSFCH resource of the sidelink resource pool. The UE generates a sidelink Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) codebook based upon one or more occasions associated with one or more PSFCH resources of the sidelink resource pool. The one or more occasions is determined or derived based upon the one or more slots and the period of N slots.
