摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Aspects described herein relate to using antenna-switched diversity (ASDIV) in wireless communications. A serving node can be communicated with using a serving radio access technology (RAT) and based on an ASDIV configuration, wherein the ASDIV configuration defines an antenna switching configuration including a state of one or more switches in an ASDIV switch group for switching between one or more antennas for the communicating based on sensing one or more parameters of the communicating. It can be determined whether a target RAT supports operating using a same ASDIV switch group as the serving RAT. A target node can be communicated with using the target RAT and based on the ASDIV configuration where the target RAT operates using the same ASDIV switch group as the serving RAT.

摘要： The various embodiments include methods and apparatuses for canceling nonlinear interference during concurrent communication of multi-technology wireless communication devices. Nonlinear interference may be estimated using a multilayer perceptron neural network with Hammerstein structure by dividing an aggressor signal into real and imaginary components, augmenting the components by weight factors, executing a linear combination of the augmented components, and executing a nonlinear sigmoid function for the combined components at a hidden layer of multilayer perceptron neural network to produce a hidden layer output signal. At an output layer, hidden layer output signals may be augmented by weight factors, and the augmented hidden layer output signals may be linearly combined to produce real and imaginary components of an estimated jammer signal. A linear filter function may be executed for the components of the jammer signal, and to produce a nonlinear interference estimate used to cancel the nonlinear interference of a victim signal.

摘要： Various embodiments leverage the typical manner in which a RAT selects a supported frequency band listed in its acquisition database and the standard communications with its network indicating the supported frequency bands to avoid potential coexistence events with one or more other RATs. In particular, various embodiments include methods for avoiding band interference between RATs operating on a multi-SIM communication device by identifying the frequency bands available to each of the RATs, comparing the identified frequency bands to determine whether any RAT's frequency bands will interfere with one or more other RAT's frequency bands, and in response to determining that there is a possibility of frequency band interference, removing those interfering frequency bands from that RAT's acquisition database. As a result, during standard communications, that RAT will report to its network that it supports only non-interfering frequency bands.

摘要： Embodiments include methods implemented by a processor of a mobile communication device for managing tune-aways by a radio frequency resource supporting a first subscription to support a second subscription. The processor may determine a data loss ratio of the data of a media file that is lost in transmission to the mobile communication device. The processor may compare the data loss ratio of the data to a first data loss ratio threshold and a second data loss ratio threshold, and the processor may block a tune-away event of the radio frequency resource from the first subscription to the second subscription in response to determining that the data loss ratio of the data is greater than the first data loss ratio threshold and less than the second data loss ratio threshold.
