Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may transmit UE capability information indicating support for multiple sounding reference signal (SRS) port adaptation patterns to a network entity. Each SRS port adaptation pattern defines a series of SRS transmissions and indicates whether each SRS transmission is a single-port SRS transmission or a multi-port SRS transmission. The UE may receive, from the network entity, a configuration of the multiple SRS port adaptation patterns based on the UE capability information, UE traffic, etc. The UE may dynamically select and/or switch an SRS port adaptation pattern per time slot for sending SRS transmissions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, to a base station, assistance information that indicates a packet data convergence protocol (PDCP) preference for multiple connectivity communications from a master node and one or more secondary nodes; and receive, from the base station, a communication that indicates a routing of a sequence of PDCP packages across the master node and one or more active secondary nodes. Numerous other aspects are provided.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for an SCG measurement configuration and adding/switching enhancement. A UE may receive information associated with an MCG and training, based on at least one of the information associated with the MCG or historical information of the UE for an SCG, an ML model of UE, of network and interworking in between that indicates whether a location of the UE is within a coverage area of the SCG. The UE may communicate with a base station based on an indication of the ML model. The indication of the ML model may be indicative of whether the UE is within the coverage area of the SCG.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to minimizing interference by controlling beam width of a wireless device. In certain aspects, a method of minimizing interference by controlling beam width of a wireless device, such as a user equipment (UE), includes configuring antenna elements of the UE to communicate in a serving cell using a first beam, monitoring a channel quality metric in the serving cell, and re-configuring the antenna elements of the UE to perform mobility measurements of one or more neighboring cells using a second beam broader than the first beam if the metric falls below a threshold value.

Abstract: A user equipment (UE) enhances battery power during a connected discontinuous reception (C-DRX) off period. In one instance, the UE determines whether data arrives in a buffer of the UE and when a scheduling request occasion falls into a C-DRX off period (connected discontinuous reception off period). The UE also delays sending a scheduling request when uplink pre-scheduling is supported by a serving base station based on the determining and based on a periodicity of uplink (UL) prescheduling for periodic uplink prescheduling and/or a length of an uplink pre-scheduled grant for non-periodic uplink prescheduling.

Abstract: A user equipment (UE) reduces call drops caused by a delayed transmission of a measurement report. In one instance, the UE enters a sleep duration in a current C-DRX cycle (connected discontinuous reception cycle) while in connected mode on a serving cell of a first RAT (radio access technology). The UE then evaluates one or more neighbor cells of a second RAT, for potential handover, during the sleep duration by performing inter radio access technology (IRAT) measurement. The UE also determines whether to wake up prior to a scheduled end of the sleep duration and send a scheduling request before the scheduled end when inter radio access technology (IRAT) measurement is completed. The determination can be based on a signal quality of the serving cell, a signal quality of the at least one neighbor cell, and a remaining time of the sleep duration in the current C-DRX cycle.

Abstract: A user equipment (UE) performs combined gap and gap-less measurement procedures. In one instance, the UE performs inter-radio access technology (IRAT) measurement of a neighbor frequency of a second radio access technology (RAT) during a measurement gap allocated by a base station of a first RAT in response to a trigger for inter-RAT handover from the first RAT to the second RAT. The UE also performs downlink timing detection of the neighbor frequency of the second RAT with a second receive chain based on the IRAT measurement.
