1. A target apparatus, comprising:
a transceiver;
a memory; and
a processor communicatively coupled to the transceiver and the memory,
wherein the processor, the transceiver, and/or the memory are configured to:
receive control information from one or more originating apparatuses, the control information indicating scheduling of resources of a data channel for carrying a plurality of transmissions from the one or more originating apparatuses and intended for the target apparatus;
listen on the data channel for the plurality of transmissions based on the control information; and
send a multi-transmission negative acknowledgment (NACK) in a NACK-only mode to multiple originating apparatuses on a feedback channel to inform the multiple originating apparatuses that there is a not-successfully-received group of transmissions, the not-successfully-received group comprising multiple transmissions of the plurality of transmissions that were not successfully received at the target apparatus when listened for on the data channel, and the multi-transmission NACK being a single feedback, wherein the multiple transmissions of the not-successfully-received group are carried on a particular subchannel of the data channel and the subchannel is a minimum unit for scheduling a physical sidelink shared channel (PSSCH).
