removing control of receive-chain components from the first SIM and providing control of the receive-chain components to the second SIM for the predetermined period of time.

11. One or more non-transitory computer readable media having instructions, that when executed, cause a user equipment (UE) to:

identify an idle-mode gap within a data stream for a first subscriber identity module (SIM) of the UE that is to allow for idle-mode operations for a second SIM of the UE; and

generate a post-idle-mode gap feedback message based on a pre-idle-mode gap feedback measurement, wherein the post-idle-mode gap feedback message is to indicate a quality of a wireless communication channel after the idle-mode gap,

13. The one or more non-transitory computer readable media of claim 11 , wherein the instructions, when executed, further cause the UE to:

generate a pre-idle-mode gap feedback message; and

transmit the pre-idle-mode gap feedback message to a radio access node transmission point prior to the idle-mode gap.

14. A user equipment (UE) comprising:

a subscriber identity module (SIM) port to receive a plurality of SIMs;

communication circuitry coupled with the SIM port to:

process a data stream for a first SIM coupled with the SIM port;

provide an idle-mode gap to allow reception or transmission of an idle-mode message for a second SIM coupled with the SIM port; and

feedback control circuitry coupled with the communication circuitry and configured to reuse a channel feedback measurement to indicate a condition of a wireless communication channel during the idle-mode gap is the same as a condition of the wireless communication channel prior to the idle-mode gap,

wherein the feedback control circuitry is to transmit a post-idle-mode gap feedback message that includes a channel quality indicator (CQI) that corresponds to a CQI index associated with a modulation scheme and a coding rate.
