Abstract: A configuration to enable a UE to determine a slot direction for communication with a base station while operating in half duplex FDD with carrier aggregation. The apparatus receives a first indication of a slot pattern for a plurality of slots associated with at least one component carrier assigned to the UE, wherein the first indication indicates that each of the plurality of slots is one of an uplink slot, a downlink slot, a special slot, or a flexible slot, and the plurality of slots includes a flexible slot. The apparatus receives, from the base station, a second indication indicating whether the flexible slot is the uplink slot or the downlink slot. The apparatus communicates with a base station based on at least one of the first indication or the second indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a reference signal or channel conveying a paging indicator. The UE may determine, based on the paging indicator, whether to monitor a paging control channel including a scheduling grant for a paging shared channel communication. The UE may estimate time or frequency information for receiving the paging control channel based at least in part on a result of the determining, and receiving the paging control channel containing based at least in part on the result of the determining and the estimated time or frequency information, or skipping monitoring the paging control channel based at least in part on the result of the determining. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station may determine collision avoidance information for avoiding collisions of physical random access channel communications from one or more user equipment. The collision avoidance information may include subcarrier spacing information and/or beam correspondence information. The first base station may transmit the collision avoidance information to a second base station. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a capability of the UE is sufficient for a make-before-break (MBB) handover from a source set of cells to a target set of cells, wherein the source set of cells is provided by a first set of transmit/receive points (TRPs) and the target set of cells is provided by a second set of TRPs; and selectively perform the MBB handover using a first capability configuration for the MBB handover or a second capability configuration for the MBB handover based at least in part on whether the capability of the UE is sufficient for the MBB handover. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for beam management for make-before-break (MBB) handover. A method that may be performed by a user equipment (UE) includes establishing a first cell connection with a first base station (BS) while maintaining an existing second cell connection with a second BS, and determining that a first transmission time of a first signal transmitted by the first BS is less than a threshold time duration from a second transmission time of a second signal transmitted by the second BS. In some examples, the first signal is associated with one or more first communication metrics and the second signal is associated with one or more second communication metrics, wherein each of the one or more first communication metrics and the one or more second communication metrics comprise one or more quality of service (QoS) metrics.

Abstract: Aspects described herein relate to receiving, from a serving cell, a configuration for performing conditional handover to one or more target cells, establishing, based on detecting a condition from the configuration, a connection with a target cell for performing handover to the target cell, and transmitting, based on establishing the connection with the target cell and based on determining that the conditional handover is of a type where a source connection with the source cell remains, a notification to the serving cell.

Abstract: In a legacy gNB (e.g., pre-Rel. 17 gNB), RC UEs with only 1 or 2 receive antennas may have a geographic coverage area for control data and traffic data that is smaller than their geographic coverage area for SSB with respect to certain legacy gNBs. By contrast, at least some new gNBs (e.g., Rel. 17+ gNBs) have the capability to provide uniform geographic coverage for RC UEs with respect to SSB, control data and traffic data. In an aspect of the disclosure, a particular class of UEs (such as RC UEs) is steered towards particular cells (e.g., Rel. 17+ gNBs) via one or more biased class-specific cell selection parameters included in system information from the cells.

Abstract: A UE may be operating in a wireless communication network having a UE-centric medium access control layer, and the UE may detect presence of a trigger event to signal a base station of the wireless communication network. The UE may identify one of a plurality of functionalities corresponding to the trigger event, and may generate a chirp signal that includes chirp purpose indicator and a chirp message, wherein the chirp purpose indicator and a format of the chirp message correspond to the identified one of the plurality of functionalities. Accordingly, the UE may transmit the chirp signal having the chirp purpose indicator to the base station, which may provide a chirp response message that includes message contents that relate to the chirp purpose indicator.
