Abstract: A user equipment (UE) may determine an amount of energy with which the UE is able to transmit in a first network. The UE may send, to a base station, information indicating the determined amount of energy. The UE may receive, from the base station, scheduling information based on the information indicating the determined amount of energy. The base station may receive, from the UE, the information indicating the amount of energy with which the UE is able to transmit in a first network. The base station may determine scheduling information based on the information indicating the amount of energy with which the UE is able to transmit in the first network, and the scheduling information may prevent the UE from exceeding a threshold amount of energy for a time period. The base station may send, to the UE, information indicating the scheduling information.

Abstract: Wireless communications systems and methods related to improving user equipment (UE) mobility performance are provided. A wireless communication device camps on a first cell operating on a first carrier frequency. The wireless communication device receives, from the first cell, cell selection priority information indicating a priority for each of a plurality of carrier frequencies. The wireless communication device evaluates each of two or more candidate cells over an evaluation time duration associated with each candidate cell, wherein an end time of the evaluation time duration of a candidate cell associated with a lower priority carrier frequency is configured to be after an end time of the evaluation time duration of a candidate cell associated with a higher priority carrier frequency. The first wireless communication device selects a second cell from the two or more candidate cells for camping based at least in part on the evaluation of the second cell.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include a wireless communications device determining an inter-modulation distortion value between simultaneous communications on a first configuration of a first radio access network and a second configuration of a second radio access network, and dynamically switching between a non-standalone mode and a standalone mode of operation, based on the inter-modulation distortion value and a quality of service requirement for the standalone mode. The wireless communications device may also provide for time division multiplexing communications on a first RAT and a second RAT wherein only the first or second RAT is active during a period of time, and wherein the first RAT is an anchor for the second RAT.

Abstract: Aspects of the disclosure relate to dual connectivity reporting. In one example, a dual connectivity communication is established, which includes a communication with a master node according to a first radio access technology (RAT), and a communication with a secondary node according to a second RAT. A change in measurement capability is then detected, and subsequently reported to the master node and/or secondary node. In another example, a scheduling entity establishes a first or second communication of a dual connectivity communication with a scheduled entity. The first communication is established according to a first RAT when operating as a master node, and the second communication is established according to a second RAT when operating as a secondary node. An indication is then received from the scheduled entity of a change in measurement capability, and the first and/or second communications are reconfigured in response to the change in measurement capability.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may detect a collision of paging messages for a first subscription and a second subscription of the wireless device during a paging processing duration, the first receive chain including at least one antenna path. The wireless device may determine that, in a connected mode, it is configured to operate a second receive chain with one or more additional antenna paths, and may allocate, for a subsequent instance of the paging processing duration, the first subscription to one of the first receive chain or the second receive chain, and the second subscription to the other of the first receive chain or the second receive chain. The wireless device may monitor, during the subsequent instance of the paging processing duration, for a first paging message and a second paging message using the first and second receive chains.

Abstract: Methods and apparatus are provided for quick recovery of missed packets after a user equipment (UE) tunes back to a first network after tuning away from the first network. The UE may determine that a trigger event has occurred, and in response to the determination, modify a negative acknowledgement (NACK) timing configuration from a default configuration. Modifying the NACK timing configuration may include using an aggressive NACK timing configuration for a configurable period of time, in response to detecting a trigger event. The trigger event may include detecting missed packets after a tune back, unavailability of sufficient memory to hold packets until a gap created by missed packets may be filled, or tuning back to a network.

Abstract: Examples described herein relate to enhancing data communication performance in a wireless communication network including a first subscription associated with a first radio access technology (RAT) and a second subscription associated with a second RAT, where the wireless communication device uses a same radio frequency (RF) resource to communicate over both the first RAT and the second RAT. The first RAT is used, in part, for data operations while the second RAT is used, in part, for voice operations. During idle state voice operations, the RF resource is reallocated from performing data operations to performing idle state voice operations, causing interruptions in the data operations. The wireless communication device adjusts at least one or a duration and an occurrence of the idle state voice operations to reduce the impact on the data operations.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for transitioning between short DRX and long DRX cycles based on service type to improve performance (e.g., reduce delay) while limiting power consumption. In one example, the UE switches to a long DRX cycle after a DRX Short Cycle Timer, or drxShortCycleTimer, expires. The UE may also switch to a long DRX if the UE receives long DRX MAC control element (CE) from a gNB. In another example, a gNB may configure a radio bearer from a set of radio bearers (data radio bearer (DRB) and/or signal radio bearer (SRB)), denoted by S, to trigger the UE to enter a short DRX cycle.

Abstract: Methods, systems, and apparatuses for wireless communication are described. A user equipment (UE) may receive information from a network node. The system information may include inter-frequency configuration and measurement reporting configuration. The UE may perform a measurement of a frequency or multiple frequencies that are associated with the inter-frequency configuration. Subsequent to the measurement, the UE may transmit a report of the measurement of the frequency or multiple frequencies to the network node during a radio resource control (RRC) connection procedure based on the measurement reporting configuration.
