Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a physical uplink control channel resource, dedicated to the UE for transmitting a feedback message for group-common downlink control information (DCI), based at least in part on a resource configuration. The UE may transmit the feedback message based at least in part on whether the group-common DCI is successfully received. Numerous other aspects are provided.
Claims34
A method of wireless communication performed by a user equipment (UE), comprising:
- determining a physical uplink control channel (PUCCH) resource, dedicated to the UE for transmitting a feedback message for group-common downlink control information (DCI), based at least in part on a resource configuration and a PUCCH resource indicator (PRI) corresponding to the UE in the group-common DCI;
- receiving an indication of a common offset in the group-common DCI;
- receiving an indication of a UE-specific offset in an RRC message;
- and
- transmitting the feedback message, after a specified amount of time from a receipt of an end of the group-common DCI, based at least in part on whether the group-common DCI is successfully received, wherein the specified amount of time includes the common offset and the UE-specific offset.

A method of wireless communication performed by a network entity, comprising:
- transmitting group-common downlink control information (DCI) to a group of user equipments (UEs), wherein the group-common DCI includes an indication of a common offset corresponding the group of UEs;
- transmitting an indication of a UE-specific offset in an RRC message to a UE in the group of UEs;
- determining a physical uplink control channel (PUCCH) resource, dedicated to the UE for transmitting a feedback message for the group-common DCI, based at least in part on a resource configuration for the UE and a PUCCH resource indicator (PRI) corresponding to the UE in the group-common DCI;
- and
- receiving the feedback message from the UE in the PUCCH resource dedicated to the UE, wherein the feedback message is transmitted from the UE after a specified amount of time from a receipt of an end of the group-common DCI at the UE, and wherein the specified amount of time includes the common offset and the UE-specific offset.
2 more elements
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- determine a physical uplink control channel (PUCCH) resource, dedicated to the UE for transmitting a feedback message for group-common downlink control information (DCI), based at least in part on a resource configuration and a PUCCH resource indicator (PRI) corresponding to the UE in the group-common DCI;
- receive an indication of a common offset in the group-common DCI;
- receive an indication of a UE-specific offset in an RRC message;
- and
- transmit the feedback message, after a specified amount of time from a receipt of an end of the group-common DCI, based at least in part on whether the group-common DCI is successfully received, wherein the specified amount of time includes the common offset and the UE-specific offset.
