Indication of whether configured grant physical uplink shared channel is to be transmitted
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of whether a configured grant physical uplink shared channel (CG-PUSCH) is to be transmitted, the indication being transmitted prior to a first configured symbol of the CG-PUSCH. The UE may transmit a communication in accordance with the indication. Numerous other aspects are described.

9 . The UE of claim 1 , wherein the one or more processors, to transmit the indication, are configured to transmit the indication based at least in part on the CG-PUSCH being associated with a first priority level, a second uplink channel overlapping the CG-PUSCH being associated with a second priority level, and the first priority level being higher than the second priority level.
10 . The UE of claim 1 , wherein the indication comprises uplink control information (UCI) on a second uplink channel.
11 . The UE of claim 10 , wherein the UCI is jointly encoded with hybrid automatic repeat request feedback on the second uplink channel.
12 . The UE of claim 10 , wherein the UCI punctures the second uplink channel.
13 . The UE of claim 1 , where the one or more processors, to transmit the indication, are configured to transmit the indication in accordance with one or more time thresholds.
14 . The UE of claim 13 , wherein the one or more processors are further configured to receive configuration information indicating the one or more time thresholds.
15 . The UE of claim 13 , wherein the one or more processors are further configured to transmit capability signaling indicating a capability associated with the one or more time thresholds.
16 . A network node for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
receive an indication of whether a configured grant physical uplink shared channel (CG-PUSCH) is to be transmitted, the indication being received prior to a first configured symbol of the CG-PUSCH; and
receive a communication in accordance with the indication.
17 . The network node of claim 16 , wherein the one or more processors, to receive the indication, are configured to receive the indication in an occasion of the CG-PUSCH.
18 . The network node of claim 17 , wherein the occasion is a first occasion of the CG-PUSCH and wherein the indication indicates whether the CG-PUSCH is to be transmitted in a second occasion.
19 . The network node of claim 16 , wherein the indication indicates that the CG-PUSCH is to be transmitted, and wherein the one or more processors, to receive the communication, are configured to receive the communication via the CG-PUSCH.
20 . The network node of claim 16 , wherein the indication is based at least in part on a scrambling sequence of a demodulation reference signal of a communication using a second uplink channel.
21 . The network node of claim 16 , wherein the indication comprises uplink control information (UCI) on a second uplink channel.
22 . The network node of claim 21 , wherein the one or more processors, to receive the indication, are configured to receive the indication on a PUSCH, associated with a configured grant, that starts earlier than the CG-PUSCH.
23 . A method of wireless communication performed by a user equipment (UE), comprising:
transmitting an indication of whether a configured grant physical uplink shared channel (CG-PUSCH) is to be transmitted, the indication being transmitted prior to a first configured symbol of the CG-PUSCH; and
transmitting a communication in accordance with the indication.
24 . The method of claim 23 , wherein the indication indicates that the CG-PUSCH is to be transmitted, and wherein transmitting the communication further comprises transmitting the communication using the CG-PUSCH.
