Group semi-persistent scheduling for path diversity

A method for wireless communications by a first user equipment (UE), comprising:

• receiving radio resource control (RRC) signaling from a node configuring a group semi-persistent scheduling (SPS) radio network temporary identifier (Group-SPS-RNTI) associated with one or more SPS resources for a group of UEs and configuring a group identifier (ID) associated with the group of UEs, wherein the group of UEs includes at least one or more first UEs, including the first UE and a second UE;
• receiving a downlink control information (DCI) from the node including the Group-SPS-RNTI and the group ID to activate the one or more SPS resources for the group of UEs;
• receiving data transmitted from the node in a physical downlink shared channel (PDSCH) using the one or more SPS resources, wherein the RRC signaling, the DCI, or the PDSCH includes an identifier of the second UE as a target UE for the one or more first UEs to retransmit the data;
• and
• retransmitting the data to the second UE.

A method for wireless communications by a second user equipment (UE), comprising:

• receiving radio resource control (RRC) signaling from a node configuring a group semi-persistent scheduling (SPS) radio network temporary identifier (Group-SPS-RNTI) associated with one or more SPS resources for a group of UEs and configuring a group identifier (ID) associated with the group of UEs, wherein the group of UEs includes the second UE and one or more first UEs;
• receiving downlink control information (DCI) comprising a common DCI including the group ID and the Group-SPS-RNTI to activate the one or more SPS resources for the group of UEs;
• monitoring the one or more SPS resources for a data transmission from the node;
• and
• receiving a retransmission of the data from at least one of the one or more first UEs.

An apparatus for wireless communications, comprising:

• a memory;
• and
• at least one processor coupled with memory, the processor and memory configured to:
• output radio resource control (RRC) signaling configuring a group of apparatuses with a group semi-persistent scheduling (SPS) radio network temporary identifier (Group-SPS-RNTI) associated with one or more SPS resources and configuring a group identifier (ID) associated with the group of apparatuses, wherein the group of apparatuses includes at least a first UE and one or more second UEs;
• output a downlink control information (DCI) including the Group-SPS-RNTI and the group ID to activate the one or more SPS resources for the group of apparatuses;
• and
• output data, for the first UE, in a physical downlink shared channel (PDSCH) to the group of apparatuses using the SPS resource, wherein the RRC signaling, the DCI, or the PDSCH includes an identifier of the first UE as a target UE for the one or more second UEs to retransmit the data.
