Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure a first channel associated with a first subscriber identity module (SIM), the first SIM associated with data traffic. The UE may configure a second channel associated with a second SIM in a dual SIM dual active (DSDA) mode. The UE may detect, on the second channel, a subscription related data stream that includes voice call traffic. The UE may determine, based on detecting the subscription related data stream, to switch the data traffic from the first SIM to the second SIM based at least in part on a UE operation mode. The UE may switch the data traffic from the first SIM to the second SIM based at least in part on the determination to switch the data traffic. 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 control channel message encoded according to a first format that is associated with a different set of shared data channel parameters than a second format supported by the UE. The second format is a legacy format relative to the first format. The UE may further determine that the control channel message is encoded according to the first format based at least in part on comparing one or more bit values, of the control channel message, in bit positions corresponding to a set of bits defined by the second format, and one or more expected bit values defined by the first format. The UE may select one or more resources for transmission based at least in part on information included in the control channel message. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE), such as a roadside unit (RSU), located in an area of limited or no global navigation satellite system (GNSS) coverage may circulate sidelink synchronization signal (SLSS) neighbor information, such as in the form of an SLSS neighbors list (SNL). The SLSS neighbor information may include one or more of an index number, an SLSS identifier (ID), a timing source in-coverage flag, an RSU ID, a hop ID, a geographic location, a transmission synchronization offset, a synchronization source, and/or a coordinated universal time (UTC) time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain one or more joint scheduling rules associated with Long Term Evolution (LIE) communications and New Radio (NR) communications in a half-duplex communication system. The UE may identify a channel busy ratio (CBR) associated with the half-duplex communication system. The UE may prioritize an LTE communication or an NR communication based at least in part on the one or more joint scheduling rules and the CBR. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for synchronizing a UE's timing for sidelink communications with one or more other UEs. The techniques may be used, for example, in NR V2X systems to maintain sidelink timing synchronization when a UE is outside the coverage area of a synchronization source such as a global navigation satellite system (GNSS).

Abstract: Certain aspects of the present disclosure provide techniques for collision mitigation in sidelink. A method that may be performed by a user equipment (UE) includes measuring channel busy ratio (CBR), estimating a number of UEs using the channel, estimating a congestion level based on the CBR and the estimated number of UEs. A method that may be performed by a sidelink UE includes determining a semi-persistent scheduling (SPS) resource reservation including first subframes, determining second subframes for generated packet transmission, determining to skip transmission in the second subframes, listening during the second subframes for another sidelink UE’s transmission, and determining whether to reselect resources. Another method includes listening during a first subframe for another sidelink UE’s transmission, detecting the transmission collides with a scheduled transmission resource for the sidelink UE based on an amount of frequency resource overlap, and determining to reselect resources.

Abstract: The present disclosure relates to methods, devices and software that can be used for preventing damage to RF front end equipment used in wireless communication systems. In some aspects, a user equipment (UE) may establish a first communication having a first priority, wherein the first communication is associated with a first subscriber in a connected mode. The UE may establish a second communication having a second priority, wherein the second communication is associated with a second subscriber in the connected mode. The UE may identify a state of a transmit/receive (TRX) switch shared between the first communication and the second communication. The UE may perform, based at least in part on the state of the TRX switch, at least one of the first communication or the second communication using a TRX switching configuration.

Abstract: Certain aspects of the present disclosure provide techniques for user equipment (UE) autonomous sidelink resource selection. A method that may be performed by a UE includes performing autonomous sidelink resource selection. The selection includes excluding resources, from a first resource set, associated with transmissions at a signal strength above a signal strength threshold to form a second resource set. The selection includes determining a resource amount in the second resource set is at or above a threshold percentage of a resource amount in the first resource set. The selection includes excluding, from the second resource set, resources associated with physical sidelink control channels (PSCCHs) without excluding resources associated with physical sidelink shared channels associated with the PSCCHs to form a third resource set. The selection includes randomly selecting resources for a PSCCH transmission from the third resource set. The method includes sending the PSCCH transmission using the randomly selected resources.
