Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a negative acknowledgment (NACK) associated with a downlink communication, and may transmit a channel state information (CSI) report based at least in part on transmitting the NACK associated with the downlink communication. In some aspects, a base station may receive, from a UE, a NACK associated with a downlink communication, and may monitor for the CSI report based at least in part on receiving the NACK. Numerous other aspects are provided.
Claims26
A method of wireless communication performed by a user equipment (UE), comprising:
- transmitting a negative acknowledgment (NACK) associated with a downlink communication;
- and
- transmitting a channel state information (CSI) report based at least in part on transmitting the NACK associated with the downlink communication,
- wherein transmission of the NACK triggers CSI report repetition, and
- wherein the CSI report repetition comprises transmitting the CSI report multiple times.
A method of wireless communication performed by a base station, comprising:
- receiving, from a user equipment (UE), a negative acknowledgment (NACK) associated with a downlink communication;
- and
- monitoring for a channel state information (CSI) report based at least in part on receiving the NACK associated with the downlink communication,
- wherein transmission of the NACK triggers CSI report repetition, and
- wherein the CSI report repetition comprises transmitting the CSI report multiple times.
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:
- transmit a negative acknowledgment (NACK) associated with a downlink communication;
- and
- transmit a channel state information (CSI) report based at least in part on transmitting the NACK associated with the downlink communication,
- wherein transmission of the NACK triggers CSI report repetition, and
- wherein the CSI report repetition comprises transmitting the CSI report multiple time.
A base station for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- receive, from a user equipment (UE), a negative acknowledgment (NACK) associated with a downlink communication;
- and
- monitor for a channel state information (CSI) report based at least in part on receiving the NACK associated with the downlink communication,
- wherein transmission of the NACK triggers CSI report repetition, and
- wherein the CSI report repetition comprises transmitting the CSI report multiple times.
