Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate one of a conditional handover (CHO) procedure or a conditional primary secondary cell addition/change (CPAC) procedure. The UE may perform a response action with regard to a configuration of the other of the CHO procedure or the CPAC procedure based at least in part on initiating the one of the CHO procedure or the CPAC procedure. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatuses for early measurement associated with configuring with multiple secondary nodes (SNs). In one aspect, the configuration of multiple SNs may be improved by allowing a master node (MN) to determine a multi-SN configuration based at least in part on measurements of actual channel conditions as seen by the UE. Enabling the MN to receive the measurement information early during a process associated with establishing a connection between the UE and the MN may thereby improve efficiency and reduce latency associated with the configuration of multiple SNs.

Abstract: This disclosure provides systems, methods, and apparatuses for low latency switching between a plurality of secondary nodes (SNs) based on a configuration for the plurality of the SNs provided to a user equipment (UE). In one aspect, the UE may obtain measurements for the plurality of the SNs according to the configuration during dual connectivity communications with a master node (MN). The MN or the UE may facilitate switching between the plurality of the SNs based on the measurements.

Abstract: A delta configuration is signaled for handover of a wireless communication device (e.g., a user equipment, UE) from a first form of connectivity to a second form of connectivity. For example, a UE with master cell group (MCG) connectivity may be handed-over to multiple radio access technology-dual connectivity (MR-DC). In some examples, a UE with standalone (SA) connectivity may be handed-over to non-standalone (NSA) connectivity (e.g., dual connectivity). In conjunction with this handover the UE may be signaled as to whether the UE is to reuse a configuration from the first connectivity mode during the second connectivity mode.

Abstract: Certain aspects of the present disclosure provide techniques for resolving paging collisions, for example, for a UE camped on multiple cells. In some cases, a UE detects, based on paging configurations, a conflict between configured paging occasions of at least two cells on which the UE is camped, signals an indication of the conflict to at least one of the cells, and receives information regarding a new paging configuration designed to resolve the conflict. In some cases, a UE identifies a different cell to camp on that is not subject to the conflict, wherein the different cell is not as good a candidate for cell selection as one of the conflicting cells in terms of cell selection criteria, and camps on the identified cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit an announcement that indicates a plurality of future resource reservations. The wireless communication device may transmit multiple sets of announcements that indicate one or more reservations and may vary the transmission frequency thereof based on proximity to the communications. The wireless communication device may transmit an announcement that indicates a future communication and a cancellation indication that indicates a cancellation of the communication. The wireless communication device may transmit a preemption indication that indicates that resources reserved for an announced future communication have been preempted for another communication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving a configuration message from a base station for supporting random access channel (RACH) type selection by the UE. The configuration message may include one or more reference signals and one or more link quality thresholds corresponding to the one or more reference signals. The UE may generate measurements of the reference signals and determine link quality for communications between the UE and the base station based on the measurements. Based on a comparison between the link quality to corresponding link quality thresholds, the UE may select a two-step random access procedure, a four-step random access procedure, or both for establishing a connection with the base station. In some cases, the UE considers system loading information, transmission parameters, or random access rules in selecting the random access procedure.

Abstract: Certain aspects of the present disclosure provide techniques for sending a configuration for conditional configured grant (CG) occasions for uplink transmission to a user equipment (UE). Each conditional CG occasion may be associated with multiple conditional CG resources. Each conditional CG resource may be associated with a sending window. The UE may monitor within sensing windows for conditional CG resources of a certain conditional CG occasion for over the air (OTA) signals from other UEs to determine if the conditional CG resources are available for uplink transmission. The UE may skip the conditional CG occasion when the conditional CG resources are not available. The UE may perform uplink transmission on the conditional CG resources when the conditional CG resources are available.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently collecting and reporting minimization of drive test (MDT) measurements for one or more radio access technology (RAT) types and/or for multiple base stations in a dual connectivity deployment. In one example, a user equipment (UE) may receive an MDT measurement configuration indicating a first RAT type for collecting measurements and a second RAT type for reporting measurements. In this example, the UE may use the measurement configuration to collect MDT measurements for the first RAT type, and the UE may report the MDT measurements to a base station associated with the second RAT. Further techniques for efficiently collecting and reporting MDT measurements in a dual connectivity deployment are also described herein.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may switch from a first group of search space sets for monitoring a physical downlink control channel (PDCCH) to an empty group of search space sets. The UE may refrain from monitoring the PDCCH based at least in part on switching to the empty group. In some aspects, the UE may switch from a first group of PDCCH search space sets to at least one dormant group of PDCCH search space sets identified in configuration information. The UE may also process one or more PDCCH search space sets of the at least one dormant group of PDCCH search space sets based at least in part on the received configuration information. Numerous other aspects are provided.
