Abstract: Various embodiments may provide systems and methods for managing transmit (TX) timing of data transmissions. The methods include applying a plurality of radio frequency (RF) channel factors related to data uplink transmissions by the wireless device to a TX timing model configured to provide as an output a TX timing for a data transmission to a base station and a number of carriers for sending the data transmission, and selecting a TX time and a number of carriers for sending a next data transmission to the base station based in part on the TX timing model output.

Abstract: A UE may transmit to a base station, and the base station may receive from the UE, via an RRC message, an IDC interference indication. The IDC interference indication may be associated with at least one victim reception or at least one aggressor transmission. The IDC interference indication may include at least one of a first frequency range associated with the at least one victim reception, information associated with the at least one aggressor transmission, a first requested BWP associated with the at least one victim reception, or a second requested BWP associated with the at least one aggressor transmission. The base station may identify at least one interference mitigation measure based on the IDC interference indication. The UE and the base station may communicate based on the at least one interference mitigation measure.

Abstract: Aspects for sending structured measurement data based on a specific type of measurement requested by a network are disclosed. A user equipment (UE) may receive a request from a base station for minimization of driving test (MDT) data corresponding to a specified type of measurement by the UE from a larger plurality of available MDT measurements that the UE can make. The UE can send the requested data including a structure report having results for the specified measurement type to the base station. In other aspects, a base station may send a request to a UE for minimization of driving test (MDT) data corresponding to a type of measurement by the UE. The base station may receive the requested data corresponding to the type of measurement.

Abstract: A method performed by a user equipment, UE, includes receiving a measurement configuration message comprising a logging measurement configuration from a base station. The method also includes initiating a minimization of drive tests, MDT, session in response to receiving the measurement configuration message and generating (802) an MDT log at each logging instance of a number of logging instances until completion of the MDT session. The method further includes transmitting (806), to the base station, the MDT log of each logging instance after completing the MDT session. For each received MDT log, the method determines (804) whether a current information element of a current measurement collected at a current logging instance matches a prior information element of a prior measurement collected at a prior logging instance, and removes the current information element from the MDT log of the current logging instance when the current measurement matches the prior information element.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may determine a set of inputs to a neural network configured to predict radio frequency channel conditions or a user context associated with the UE. In some aspects, the set of inputs includes historical data related to a wireless environment, a communication pattern, or a behavior pattern associated with the UE. The apparatus of the UE may determine, using the neural network and based at least in part on the set of inputs, an optimal number of aggregated carriers to maximize one or more of a power parameter or a performance parameter. The apparatus of the UE may communicate using the optimal number of aggregated carriers. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a measurement configuration for a service interruption measurement regarding a handover of the UE from a source cell to a target cell. The UE may transmit measurement information that identifies at least one of the service interruption measurement or a time value used to determine the service interruption measurement. Numerous other aspects are provided.

Abstract: A method includes monitoring, at an upper layer of the UE, PDU activity for one or more PDU sessions that are associated with one or more DNNs. The method includes determining that each of the one or more PDU sessions has a period of inactivity based on at least one of an expiration of an activity check timer, accumulated inactivity cycles, or a dormancy indication associated with each of the one or more PDU sessions. The method includes indicating, to a lower layer of the UE, to provide UE assistance information to a base station for a RRC connection release between the UE and the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network device may determine that a ping-pong condition is satisfied with regard to a Long Term Evolution (LTE) radio access technology (RAT) and a New Radio (NR) RAT. The network device may configure a dual connectivity mode for the UE based at least in part on the ping-pong condition being satisfied. The network device may cause the UE to deprioritize the NR RAT based at least in part on the ping-pong condition being satisfied. Numerous other aspects are provided.

Abstract: In one instance, a user equipment (UE) compares an expected duration of a tune away procedure with a first time remaining before a discard timer expires, a second time remaining before a downlink reordering timer (DL reordering timer) for adjusting an order of data at a buffer expires, a third time remaining before a retransmission timer expires and/or a fourth time remaining before an expected time to receive acknowledgement feedback ends. The UE also determines whether to adjust a tune away procedure based on the comparing. The tune away procedure may include the UE tuning away from a first radio access technology (RAT) to a second RAT during a communication procedure at the first RAT.
