Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. The UE may identify that the UE is operating in a high mobility environment, that a first reference signal received power associated with a first cell is decreasing, and that a second reference signal received power associated with a second cell is increasing. The UE may transmit a request for a handover from the first cell to the second cell based on the identifying, the transmitting performed at a time that may be based on one or more network-configured handover timing parameters having one or more values adjusted by the UE. The UE may receive a handover command in response to transmitting the request for handover. The UE may perform a handover from the first cell to the second cell in response to the handover command.

Abstract: Apparatus, methods, and computer-readable media for facilitating multi-tasking and smart location selection during connected-mode discontinuous reception (CDRX) mode are disclosed herein. Example techniques disclosed herein enable a UE to perform multiple tasks during a same SSBS to reduce the number of wake-up SSBSs. For example, disclosed techniques enable a UE to perform RLM tasks and loop tracking tasks during a first SSBS and thereby reduce the number of wake-up SSBSs. In some examples, the UE may also perform the search task or the measurement task during the same first SSBS and, thereby, further reduce the number of wake-up SSBSs. Example techniques disclosed herein may also enable the UE to select which SSBS occurrences to wake-up for during the OFF duration of the CDRX cycle.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive a control signal that indicates a radio resource management (RRM) configuration associated with one or more measurement thresholds for managing wireless communication links at the wireless device. The wireless device may then perform measurements for one or more synchronization signals in accordance with the RRM configuration. The wireless device may then apply an opportunistic gain to the measurements to generate modified measurements based on a quantity of radio frequency (RF) chains usable by the wireless device for communicating via the wireless communication links. The wireless device may then transmit a measurement report based on the modified measurements satisfying the one or more measurement thresholds, and may receive an additional control signal instructing the wireless device to manage the wireless communication links based on the measurement report.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a message indicating UE assistance information (UAI). In some examples, the UE may transmit a request for network assistance information (NAI) for candidate cells. The UE may receive a control message indicating the NAI and a set of candidate cells for a conditional serving cell change. The UE may perform the conditional serving cell change based on the NAI for one or more candidate cells. In some examples, the UE may select a target cell from the set of candidate cells, and the UE may receive a control message indicating one or more coverage enhancement schemes supported by the target cell. The UE may perform a random access procedure based on the one or more coverage enhancement schemes supported by the target cell.

Abstract: A UE may attempt, based on a first mode, to identify a first opportunity within a preconfigured time period for a measurement associated with at least one SCC when the at least one SCC is deactivated at the UE and the measurement associated with the at least one SCC is due based on a scheduling. Based on the first mode, a radio of the UE may not be tuned to the at least one SCC when the at least one SCC is deactivated at the UE and no measurement associated with the at least one SCC is being performed at the UE. The UE may perform, if the first opportunity is identified within the preconfigured time period, the measurement associated with the at least one SCC at the identified first opportunity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform measurements on a plurality of cells. The UE may order the plurality of cells based at least in part on multiple factors including at least a cell selection condition, the cell selection condition indicating a threshold for the measurement for cell selection. The UE may select, based at least in part on the ordering, a cell from the plurality of cells. The UE may camp on the selected cell. Numerous other aspects are provided.

Abstract: Various aspects relate to acquisition of system information (SI). In some examples, a UE uses a guard timer to control how long the UE attempts to acquire a particular type of SI. In some examples, a UE that has entered a cell may determine whether there are any remaining paging occasions (e.g., that may indicate an SI update) during a period of time. If there is an insufficient number of paging occasions remaining (e.g., zero or one), the UE may monitor for broadcast SI. In some examples, after sending a request for SI to a base station, a UE may also periodically monitor for SI broadcast by the base station (e.g., to avoid potential delays in obtaining the SI). In some examples, if a UE does not acquire SI, the UE may use default SIB information (e.g., that expedites reselection to another cell).

Abstract: Aspects are provided which allow a UE to apply CFO compensation to resolve mismatched RAPIDs caused by uplink Doppler shifts in HST deployments. The UE obtains one or more RARs each including a RAPID, where each of the RARs is responsive to a random access message including a preamble. The UE determines, in each of a threshold number of the one or more RARs, that the RAPID of a corresponding RAR is different than the preamble of a corresponding random access message. The UE then offsets a carrier frequency for each of one or more subsequent random access messages in response to the determination. As a result, mismatched RAPIDs due to uplink Doppler shifts may be avoided and RACH success rates may thereby be improved.

The UE may transmit a measurement report that includes the modified channel condition value. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit a set of spatially multiplexed synchronization signals in a same symbol period. The set of spatially multiplexed synchronization signals may indicate a parameter, such as a cell identifier, for the network entity. The network entity may select a sequence for each synchronization signal of the set. A user equipment (UE) may monitor for the set of spatially multiplexed synchronization signals during the same symbol period. The UE may differentiate each synchronization signal based on a respective sequence used to transmit each synchronization signal. The UE may determine that the set of spatially multiplexed synchronization signals were transmitted by the network entity using multiple antenna ports. The UE may determine the parameter for the network entity based on receiving the set of spatially multiplexed synchronization signals.

The channel measurement vector may indicate multiple measured channel metrics for one or more dimensions of the multi-dimensional channel response. The network entity may transmit a message that indicates one or more metrics associated with mobility management for the UE based on the report that indicates the channel measurement vector.
