In some aspects, a user equipment (UE) may transmit, to a base station, an indication of whether the UE is enabled to receive a simultaneous spatial relation update for a physical uplink control channel (PUCCH) resource group of PUCCH resources that share a same spatial relation. The UE may receive, from the base station based at least in part on the indication, the simultaneous spatial relation update for the PUCCH resource group. Numerous other aspects are provided. ## Claims ### Claim 1 A user equipment (UE) for wireless communication, comprising: a memory; and one or more processors operatively coupled to the memory, the memory and the one or more processors configured to: transmit, to a base station, an indication of whether the UE is enabled to receive a simultaneous spatial relation update for a physical uplink control channel (PUCCH) resource group of PUCCH resources that share a same spatial relation; and receive, from the base station based at least in part on the indication, the simultaneous spatial relation update for the PUCCH resource group. ### Claim 2 (depends on 1) The UE of claim 1, wherein the indication is transmitted in a UE capability information message. ### Claim 3 (depends on 1) The UE of claim 1, wherein the indication is transmitted via radio resource control signaling. ### Claim 4 (depends on 1) The UE of claim 1, wherein the indication indicates that the UE is enabled for simultaneous spatial relation updating of PUCCH resource groups for respective bandwidth parts. ### Claim 5 (depends on 1) The UE of claim 1, wherein the indication identifies a particular value to indicate that the UE is not enabled to receive the simultaneous spatial relation update. ### Claim 6 (depends on 1) The UE of claim 1, wherein the memory and the one or more processors are further configured to receive a configuration for one or more PUCCH resource groups. ### Claim 7 (depends on 1) The UE of claim 1, wherein the memory and the one or more processors are further configured to update a spatial relation for a PUCCH resource, of the PUCCH resource group, based at least in part on the simultaneous spatial relation update. ### Claim 8 (depends on 1) The UE of claim 1, wherein the memory and the one or more processors are further configured to communicate in a PUCCH resource, of the PUCCH resource group, using a beam indicated by a spatial relation of the simultaneous spatial relation update. ### Claim 9 A base station for wireless communication, comprising: a memory; and one or more processors operatively coupled to the memory, the memory and the one or more processors configured to: receive, from a user equipment (UE), an indication of whether the UE is enabled to receive a simultaneous spatial relation update for a physical uplink control channel (PUCCH) resource group of PUCCH resources that share a same spatial relation;
