User equipment (UE) indication of coverage mismatch between common search space (CSS) and user-specific search space (USS) for remaining minimum system information (RMSI) delivery
First Claim
1. A method for wireless communication by a base station (BS), comprising:
- transmitting system information to a user equipment (UE) in a first common search space (CSS) transmission;
receiving an indication of a coverage mismatch indicating that the UE decoded at least one beamformed signal transmitted by the BS in a user-specific search space (USS) and did not decode at least one beamformed signal transmitted by the BS in a subsequent CSS transmission;
responsive to receiving the indication, determining whether the system information has changed since the first CSS transmission; and
taking one or more actions based, at least in part, on the determining whether the system information has changed since the first CSS transmission.

Abstract
Certain aspects of the present disclosure provide techniques for identifying a mismatch between a user'"'"'s common search space (CSS) and user-specific search space (USS). A base station (BS) may receive an indication that a user equipment (UE) decoded at least one beamformed signal transmitted by the BS in a USS and did not decode at least one beamformed signal transmitted by the BS in a CSS. The BS may take one or more actions based, at least in part, on the indication. Similarly, a UE may decode at least one beamformed signal transmitted by a BS in a USS, transmit to the BS an indication that the UE decoded the at least one beamformed signal transmitted in the USS and did not decode at least one beamformed signal transmitted by the BS in a CSS, and take one or more actions based, at least in part, on the indication.

12. A method for wireless communication by a user equipment (UE), comprising:
-
receiving system information from a base station (BS) in a first common search space (CSS) transmission; decoding at least one beamformed signal transmitted by the BS in a user-specific search space (USS); transmitting, to the BS, an indication of a coverage mismatch indicating that the UE decoded the at least one beamformed signal transmitted in the USS and did not decode at least one beamformed signal transmitted by the BS in a subsequent CSS transmission; and taking one or more actions based, at least in part, on a determination of whether the system information has changed since the first CSS transmission. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. An apparatus for wireless communication by a base station (BS), comprising:
-
means for transmitting system information to a user equipment (UE) in a first common search space (CSS) transmission; means for receiving an indication of a coverage mismatch indicating that the UE decoded at least one beamformed signal transmitted by the BS in a user-specific search space (USS) and did not decode at least one beamformed signal transmitted by the BS in a subsequent CSS transmission; and means for, responsive to receiving the indication, determining whether the system information has changed since the first CSS transmission; and means for taking one or more actions based, at least in part, on the determining whether the system information has changed since the first CSS transmission. - View Dependent Claims (23, 24, 25)
