Abstract: Certain aspects of the present disclosure provide techniques for multi-universal subscriber identification module (USIM) and dual connectivity operation. A method that may be performed by a user equipment (UE) includes establishing a first access link, associated with a first subscriber identification module (SIM) of the UE, for communicating with a first base station; establishing a second access link, associated with the first SIM of the UE, for communicating with a second base station; establishing a third access link associated with a second SIM of the UE; identifying at least one time division multiplexing (TDM) pattern indicating a set of time periods during which to use the third access link; and tuning to the third access link for communicating using the second SIM during at least one time period of the set of time periods indicated in the TDM pattern.

Abstract: Methods, systems, and devices for wireless communications are described for radio frequency (RF) exposure limit compliance using uplink duty cycling. A user equipment (UE) may transmit a buffer status report (BSR) that indicates an amount of data that is to be transmitted by the UE, where lower priority data reported in the BSR may be throttled in order to reduce an amount of uplink resources associated with the lower priority data and thereby adjust an uplink duty cycle of the UE. The reduced uplink duty cycle may provide for additional transmit power that is available for higher priority data transmissions.

Abstract: Aspects described herein relate to communicating, based on a first subscription, with a first Radio Access Technology (RAT) over a bandwidth part (BWP) in a set of one or more configured BWPs, tuning a transceiver away from the BWP to a second frequency to communicate, based on a second subscription, with a second RAT for a period of time, tuning, after the period of time, the transceiver back to a selected BWP to communicate with the first RAT, and handling BWP parameters during or based on the tune away or tune back.

Abstract: Various embodiments include methods and user equipment (UE) for mobile-terminated call handling when a latency-sensitive service (LSS) is active on the UE. Embodiments may include determining a radio access technology (RAT) used for a latency-sensitive service (LSS) currently active on the UE in response to receiving an MT call invitation and determining whether a latency-prone service command is received that includes service commands configured to change the determined RAT used for the LSS to another RAT likely to compromise the LSS. In response to determining that a latency-prone service command is received the MT call invitation may be rejected, but in response to determining that a latency-prone service command is not received, MT call alerting may be allowed.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. The UE may identify a first set of bands associated with a first subscription and a second set of bands associated with a second subscription. The UE may determine that at least a first band from the first set of bands and at least a second band from the second set of bands share a same set of radio frequency (RF) front-end resources. The UE may then refrain from communicating on a third band from the first set of bands while communicating on a remaining set of bands, where the third band may be associated with a secondary component carrier (SCC) of a multi-carrier communications scheme. Refraining from communicating on the third band may be based on the first and second bands sharing the RF front-end resources and the third band being associated with the SCC.

Abstract: Methods, systems, and devices for wireless communications are described for handling uplink grants that have associated uplink transmission that may exceed exposure limits. Exposure limits may be based on maximum permissible exposure (MPE) limits of millimeter wave transmissions and may be determined at a user equipment (UE) and provided to a base station. If the UE receives an uplink grant for a transmission in which an associated uplink transmission would exceed the exposure limits, the UE may drop the uplink transmission prior to forming a transport block, transmit control signaling to the base station to indicate the exposure limits at the UE, or combinations thereof.

Abstract: In an aspect, a user equipment (UE) receives a parameter representing a maximum transmission power, transmits first radio frequency (RF) signals to a first node over a first wireless communication link in accordance with a first radio access technology (RAT) during a plurality of time segments, wherein the first RF signals are transmitted during the plurality of time segments at one or more first power levels, and transmits second RF signals to a second node over a second wireless communication link in accordance with a second RAT during the plurality of time segments, wherein the second RF signals are transmitted during the plurality of time segments at one or more second power levels, and wherein a sum of an average of both the one or more first power levels and the one or more second power levels over the plurality of time segments does not exceed the maximum transmission power.

Abstract: Wireless communications systems and methods related to modifying a buffer status report (BSR) are provided. In one embodiment, a first wireless communication device determines a BSR based on at least a first data size and a predicted data size. The first wireless communication device transmits to a second wireless communication device, the BSR. The first wireless communication device receives from the second wireless communication device, a scheduling grant in response to the BSR. The first wireless communication device transmits to the second wireless communication device, a communication signal based on the scheduling grant.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may camp on a cell of a first radio access technology (RAT). The UE may perform a cell search for a second RAT while camped on the cell of the first RAT, wherein the second RAT operates in a non-standalone mode with the first RAT. The UE may present, for display, an indication of whether the second RAT is available in the cell based at least in part on performing the cell search for the second RAT. Numerous other aspects are provided.
