Abstract: Methods, systems, and devices for wireless communications and capability signaling for enhanced handover processes are described. A user equipment (UE) may transmit, to a source base station, a band combination indicator to indicate at least one band combination supported by the UE. The source base station may transmit a source base station configuration and at least one band combination supported by the UE to a target base station for use during a handover procedure. The target base station may then transmit to the source base station, a target base station configuration to use in the handover procedure. The source base station may transmit to the UE, both base station configurations to be applied during the handover procedure which may include a number of band combinations. The UE may communicate during handover execution with both base stations using at least one band combination indicated in the received base station configurations.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) capability indication that indicates one or more constraints associated with a supported modulation order. In some cases, the UE capability indication may indicate that the UE supports a particular modulation order, but has a capacity constraint such that an associated data rate is limited to a data rate associated with a lower modulation order. In some cases, one or more frequency bands may be mapped to a UE constraint.

Abstract: The present disclosure relates to methods and devices for a handover procedure which may include a user equipment (UE), first base station, and a second base station. In one aspect, the UE can receive an indication to handover from the first base station to the second base station. The UE may then establish a connection with the second base station. In another aspect, the UE can maintain a connection with the first base station over a period of time during the handover. The UE can also communicate with the first base station and the second base station during the period of time based on a time division multiplexing (TDM) pattern. The TDM pattern can comprise a pattern of subframes for communicating with the first and second base station. In another aspect, the UE can release the connection with the first base station at the end of the period of time.

Abstract: Techniques for optimizing user equipment radio capability signaling for wireless communications are described. In one technique, a type of network to access for communications is determined. A capability identifier(s) associated with a set(s) of user equipment (UE) radio capabilities is determined based, at least in part, on the type of network. The capability identifier(s) is sent to the network. Upon receiving an indication of the capability identifier(s), the set(s) of UE radio capabilities associated with the capability identifier(s) is identified and stored.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive from a base station a measurement configuration signal comprising a measurement resource configuration associated with a cross-link interference signal strength measurement. The UE may perform the cross-link interference signal strength measurement for one or more UEs associated with one or more intra-frequency neighboring cells according to the measurement resource configuration, wherein the cross-link interference signal strength measurement is performed during an intra-frequency measurement gap. The UE may transmit a report of the cross-link interference signal strength measurement to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a serving cell, signaling identifying a core network type cell ranking offset parameter. The UE may rank, based at least in part on the core network type cell ranking offset parameter, a neighbor cell for reselection relative to the serving cell, wherein the neighbor cell is associated with a different core network type than the serving cell. The UE may selectively reselect to the neighbor cell based at least in part on ranking the neighbor cell for reselection relative to the serving cell. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for radio resource management (RRM) measurement and reporting for license assisted access (LAA) cells operating in unlicensed or shared frequency spectrum are described. A user equipment (UE) may receive an RRM measurement configuration including a channel occupancy parameter for measuring neighbor cells of a shared frequency band. The channel occupancy parameter may be used to determine a channel occupancy metric that may be sent to a base station for cell selection. The channel occupancy metric may include an averaged or filtered received signal strength and may be reported for serving cells and/or intra-frequency neighbor cells. A base station may further configure a UE with a discovery reference signals (DRS) measurement timing configuration (DMTC), which may include an extended DMTC search window. The UE may search for DRS transmissions from neighbor cells according to the DMTC.

Abstract: The present disclosure provides user equipment power consumption and secondary cell (SCell) activation latency reductions in wireless communication systems. For example, a UE may determine that a secondary cell activation condition has been satisfied. The UE may further transition to a secondary cell activated state based on determining that the secondary cell activation condition has been satisfied, the secondary cell activate state corresponding to a dormant SCell state. The UE may operate at least in the dormant SCell state.
