Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a first service associated with a first subscriber identity module (SIM) of the UE and a first priority. The UE may initiate a second service associated with a second SIM of the UE and a second priority. The UE may switch the first priority and the second priority during at least part of the first service or the second service. The UE may perform a communication in accordance with at least one of the first priority or the second priority. 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 establish, using a first subscription of the UE, a first communication connection associated with a first service. The UE may establish, using a second subscription of the UE, a second communication connection associated with a second service. The UE may operate in a dual subscriber identity module (SIM) dual active (DSDA) mode based at least in part on establishing the first communication connection and establishing the second communication connection. The UE may perform an action to maintain concurrent services, including the first service and the second service, while operating in the DSDA mode. 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 detect that a first subscription, of a plurality of subscriptions associated with the UE, is associated with an active service on a first cellular network. The UE may search, for a second subscription of the plurality of subscriptions, for radio access technologies (RATs) and frequency bands that are compatible with a dual active mode of the UE. In some aspects, the UE may detect that the active service on the first cellular network has ended. Accordingly, the UE may search, for the second subscription, for RATs and frequency bands that are compatible with the dual active mode of the UE and for RATs and frequency bands that are incompatible with the dual active mode, before expiry of a timer associated with a power saving state. Numerous other aspects are described.

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: 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: A method includes cellular vehicle-to-everything (CV2X) allocation collision detection and reporting. An allocation collision detection module detects control channel allocations from transmitting user equipments (UEs) in each time period of a group of time periods. A quantity of detected control channel allocations is determined in each time period. A report is then built and transmitted to at least one of the transmitting UEs. The report indicates collisions in each time period, based on the quantity and a location of the detected control channels in each time period, as well as based on a type of UE interface.

Abstract: Apparatus, methods, and computer-readable media for facilitating autonomous synchronization are disclosed herein. For example, a UE may be configured to perform an initial synchronization directly to PSCCH and PSSCH when other synchronization sources, such as GNSS, a base station, and/or SLSS, are unavailable. An example method for wireless communication at a user equipment includes receiving a PSCCH. The example method also includes performing an initial synchronization based on the PSCCH. In some examples, the method may also include receiving a PSSCH, and determining a logical subframe number modulo 10 based on the PSSCH. The logical subframe number modulo 10 may correspond to a sequence seed.

Abstract: Various embodiments enable a multi-active mobile communication device to mitigate (manage) interference by a frequency band used by a first subscription with the frequency band used by a second subscription. The device processor may generate modified power measurements for one or more frequency bands of a first subscription and use the modified power measurement(s) to cause the first subscription to switch from the frequency band that interferes with the frequency band of the second subscription. The modified power measurement may be a decreased power measurement of the first frequency band and/or an increased power measurement of a second frequency band that does not interfere with the frequency band of the second subscription. As a result, various embodiments may mitigate or otherwise manage the impact of coexistence interference between the first and second subscriptions of a multi-active mobile communication device without limiting capabilities of the device or changes to the network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, via a subscription of the UE to a network node, a UE assistance information (UAI) that indicates a reduction to one uplink multiple-input multiple-output (MIMO) layer for the subscription. The UE may transmit, via the subscription to the network node, an uplink transmission using one uplink MIMO layer on one transmit (Tx) chain of the UE based at least in part on the UAI and a timer associated with the UAI. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a multi-subscriber identity module (SIM) user equipment (UE) may communicate, using a first SIM, on a plurality of component carriers. The multi-SIM UE may select a first subset of component carriers from the plurality of component carriers based at least in part on a component carrier prioritization. The multi-SIM UE may identify an amount of memory available to a second SIM. The multi-SIM UE may tune away, based at least in part on the amount of memory available to the second SIM, from a second subset of component carriers The first subset of component carriers may be different from the second subset of component carriers. Numerous other aspects are described.
