Abstract

In some implementations, a method in a user equipment (UE) for supporting group communication service includes receiving, from a base station, a group communication on a Physical Downlink Shared Channel (PDSCH). The UE determines a first Hybrid Automatic Repeat reQuest (HARQ) information that corresponds to the group communication on the PDSCH. The UE transmits the first HARQ information. In some implementations, the UE determines a group Channel State Information (CSI) for a group communication that is transmitted by a base station on a PDSCH. The UE determines a unicast CSI for a unicast communication that is transmitted by the base station on the PDSCH. The UE transmits the group CSI. The UE transmits the unicast CSI.
