1. A user equipment (UE) for wireless communication, comprising:
one or more memories storing processor-executable code; and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
identify a plurality of tuneaway occasions in which the UE is to tune away at least one radio frequency chain of a plurality of radio frequency chains from a first subscription to a second subscription;
identify a conflict for an uplink multiple-input multiple-output (MIMO) transmission via one or more first radio frequency chains associated with the first subscription during a first tuneaway occasion of the plurality of tuneaway occasions;
switch, by the UE, the uplink MIMO transmission from the one or more first radio frequency chains to one or more available different second radio frequency chains of the plurality of radio frequency chains for the first tuneaway occasion based at least in part on the conflict associated with the one or more first radio frequency chains;
transmit the uplink MIMO transmission using the one or more available different second radio frequency chains during the first tuneaway occasion; and
perform an idle mode activity using the one or more first radio frequency chains during the first tuneaway occasion.
