CHANNEL STATE REPORTING DURING TUNE AWAY IN MULTI-SUBSCRIBER IDENTITY MODULE DEVICE

摘要

Decoding failure and throughput loss are reduced when a user equipment (UE) tunes away from a first radio access technology (RAT) to a second radio access technology. In one instance, the UE determines when one or more receive chains will tune away from a first subscriber identity module (SIM) to another SIM. The UE reports a channel state based on measurements obtained without the one or more receive chains during the determined tune away and/or during a predetermined time period before the determined tune away. The UE also reports the channel state based on measurements obtained with the one or more receive chains after the one or more receive chains return from the determined tune away.

主权项

1. A method of wireless communication for a user equipment (UE) with multiple receive chains and multiple subscriber identity modules (SIMs), comprising:
determining when at least one receive chain will tune away from a first SIM to another SIM; reporting a channel state based at least in part on measurements obtained without the at least one receive chain during a predetermined time period before the determined tune away; reporting the channel state based at least in part on measurements obtained without the at least one receive chain during the determined tune away; and reporting the channel state based at least in part on measurements obtained with the at least one receive chain after the at least one receive chain returns from the determined tune away.
