A method of wireless communication includes, in response to a trigger event detected at a first base station, performing, by the first base station, a scan of a plurality of frequencies for a synchronization signal block (SSB) transmission from a second base station. The plurality of frequencies correspond to a plurality of global synchronization channel numbers (GSCNs) associated with the first base station and the second base station. The first base station is associated with a first coverage area that is at least partially within a second coverage area associated with the second base station. The method further includes transmitting, by the first base station, one or more SSBs having an SSB configuration that is based on a result of the scan.

Scan-based synchronization signal block (SSB) configuration for a base station

Methods, systems, and devices for wireless communications are described. Some wireless communications network may operate in accordance with an open-RAN (ORAN) network specification which may support functional splitting between the ORAN distributed unit (O-DU) and the ORAN radio unit (RU) located at a base station. The O-DU may communicate with the O-RU using control messaging, and the O-DU may signal whether various resource block groups are used for data allocation by enabling or disabling bits in a bit mask parameter in a header of the control message. To increase communications efficiency and reduce overhead, the O-DU may dynamically configure the number of bits included in a bit mask based on a radio access technology (RAT) type. The O-DU may determine the size of the bit mask in the control message based on the RAT type and may generate the control message that includes the bit mask.

Certain aspects of the present disclosure provide techniques for power saving through discontinuous reception (DRX) in multiple subscriber identity module (multi-SIM) user equipment (UE). A method that may be performed by a UE includes determining a first DRX configuration associated with a first SIM and a second DRX configuration associated with a second SIM are asynchronous, generating, based on the first DRX configuration and the second DRX configuration, a synchronous DRX configuration for communicating with the first SIM and the second SIM, transmitting, to a first base station (BS) associated with the first SIM and to a second BS associated with the second SIM, an indication of the synchronous DRX configuration, and communicating with the first BS using the first SIM and the second BS using the second SIM in accordance with the synchronous DRX configuration.

Power saving through discontinuous reception (DRX) in multi-SIM user equipment (UE)

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit a request for system information based at least in part on a threshold; and receive the system information based at least in part on the request. A base station may receive a request for system information, wherein the request is based at least in part on a threshold; and transmit the system information to a user equipment (UE) associated with the request based at least in part on the request. Numerous other aspects are provided.

Threshold-based system information on demand

The present disclosure describes methods and apparatus for detecting handover failures at an AP when the AP does not have an X2 interface with at least one of its neighbors. For example, methods are provided for detecting handover failures at an AP based on at least on a UE context release command message received from a mobile management entity (MME) and/or determining that a radio resource control (RRC) connection reconfiguration (RCR) message is not delivered to the UE.
