Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may use multiple subscriber identification modules (SIMs) in dual-SIM dual-active (DSDA) communications. A DSDA UE may support identification of a set of available radio frequency (RF) resources for communications, where the set of available RF resources include multiple RF components (e.g., transmit/receive antennas), RF baseband resources (e.g., processing resources that support processing and decoding of transmissions), or combinations thereof. The set of available resources may be shared between multiple SIMs, and the UE may identify different resource partitions of the set of available resources, with different resource partitions used to provide concurrent communications of both the first SIM and the second SIM based on parameters of each SIM.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, on a first subscriber identity module (SIM) operating in a connected mode, a signal using a first antenna associated with a first antenna module. The UE may configure, for a second SIM operating in an idle mode, a second antenna associated with the first antenna module for receive operations. The UE may switch a transmit antenna associated with the first SIM from the first antenna to a third antenna associated with a second antenna module based at least in part on configuring the second antenna for receive operations and based at least in part on the first antenna module being unable to support concurrent transmission and reception of signals. The UE may transmit, on the first SIM, a signal using the third antenna. Numerous other aspects are described.

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: 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.

Abstract: Aspects of the methods and apparatus include determining that a time-to-trigger (TTT) timer has expired, and determining that a serving radio access technology (RAT) received signal characteristic is less than a signal characteristic threshold when the TTT timer has expired. Further, the aspects include determining, in response to the serving RAT received signal characteristic being less than the signal characteristic threshold, that a target RAT frequency measurement associated with a Measurement Report Message (MRM) for performing an inter-RAT (IRAT) handover cannot be completed within a time limit according to a current measurement gap configuration. Also, the aspects include calculating a measurement gap duration sufficient to complete the target RAT frequency measurement associated with the MRM for performing the IRAT handover, and configuring a new measurement gap prior to the time limit, wherein the new measurement gap comprises the calculated measurement gap duration.

Abstract: A multi-subscriber identity module (SIM) multi-standby user equipment (UE) improves recovery of an original operation of a first radio access technology (RAT) when the UE tunes away from the first RAT. In some instances, the UE communicates with the first RAT on a transmit chain and a receive chain and then tunes to a second RAT on the receive chain to monitor downlink communications or activities of the second RAT. The UE transmits on the first RAT over the transmit chain, while tuned to the second RAT. Thus, the UE continues to perform uplink transmission when the UE tunes away, which allows a base station of the first RAT to track the UE for downlink beam-forming.

Abstract translation: 当多用户识别模块（SIM）多待机用户设备（UE）远离第一RAT时，提高了第一无线电接入技术（RAT）的原始操作的恢复。 在一些情况下，UE在发射链和接收链上与第一RAT通信，然后调谐到接收链上的第二RAT，以监视第二RAT的下行链路通信或活动。 当UE在调谐到第二RAT时，通过发送链在第一RAT上进行发送。 因此，当UE调谐离开时，UE继续执行上行链路传输，这允许第一RAT的基站跟踪UE以进行下行链路波束形成。
