A method of wireless communication performed by a user equipment (UE), the method including: operating in a mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS) and a second SIM is designated as a non-default data subscription (nDDS), including the first SIM being active and the second SIM being idle; determining positions of uplink symbols and downlink symbols within a slot format of the first SIM; causing a hardware switch of the UE to couple the second SIM to an antenna of the UE during a first symbol that is configured as uplink or flexible; and performing a page decode operation by the second SIM while the second SIM is coupled to the antenna.

Controlling switch timing in time division duplexing devices

A method of wireless communication is performed by a user equipment (UE) that has a first subscriber identity module (SIM) and a second SIM. The method of wireless communication includes operating in a mode in which the first SIM is associated with a first subscription and in which the second SIM is associated with a second subscription, the first and second subscriptions being active at a same time and sharing radio frequency (RF) resources of the UE; designating the first subscription as having a higher priority status than the second subscription, analyzing a signal condition associated with the second subscription, and changing the higher priority status to apply to the second subscription based on the signal condition.

Systems and methods to designate subscription priority to set a gain state in a multi-subscriber identity module device

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adjust an amplifier of the UE to a highest gain state after a downlink period and before an uplink period. Additionally, the UE may adjust the amplifier of the UE to a lower gain state after the uplink period and before a subsequent downlink period. Numerous other aspects are described.

Amplifier adjustment to reduce latency

A method of wireless communication performed by a user equipment (UE) may include: performing, for a first subscription, a first handover from a first cell to a second cell; and performing, for a second subscription, a second handover from a third cell to a fourth cell. In some aspects, at least one of the performing the first handover or the performing the second handover is based on: a difference in signal strength between the first cell and the third cell exceeding a first threshold; and a difference in signal strength between the second cell and the fourth cell being equal to or less than the first threshold.

Joint cell selection for dual subscription dual active (DSDA) operation

A method of wireless communications by a user equipment (UE) includes detecting, in response to a bandwidth part (BWP) switch, a first BWP of a first carrier aggregation signal and a second BWP of a second carrier aggregation signal. The first BWP of the first carrier aggregation signal and the second BWP of the second carrier aggregation signal are each within a predetermined frequency range of each other. The method also includes tuning a radio frequency (RF) channel to a center of a wideband channel including the first BWP and the second BWP. The method further includes processing the wideband channel including both the first BWP of the first carrier aggregation signal and the second BWP of the second carrier aggregation signal with a single phase locked loop (PLL).

Power saving by combining multiple bandwidth parts (BWPs) into a single wideband channel

Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE). The method generally includes: receiving signaling on a plurality of carriers, and dynamically assigning non-linear interference cancellation (NLIC) to a subset of the plurality of carriers based on at least one criteria, wherein the NLIC is available to a number of carriers that is less than a total number of carriers in the plurality of carriers.

Enhanced non-linear interference cancellation (NLIC) operation

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may tune a first voltage controlled oscillator (VCO) to an offset frequency from a particular frequency, wherein the offset frequency differs from the particular frequency by an offset, wherein the offset is based at least in part on at least one parameter, and wherein the UE is configured to operate in an at least one carrier mode associated with at least one time division duplexed carrier; and communicate, while the first VCO is tuned to the offset frequency, a communication associated with a second VCO, wherein the second is tuned to the particular frequency. Numerous other aspects are provided.

Techniques and apparatuses for mitigating voltage controlled oscillator frequency disturbance

Certain aspects of the present disclosure provide methods and apparatus for wireless communication. One example apparatus generally includes a first transceiver configured to transmit and receive signals in a first frequency band and a second transceiver configured to transmit and receive signals in a second frequency band. The apparatus may also include a processing system coupled to the first transceiver and the second transceiver. The processing system may be configured to dynamically assign transmission operations or reception operations of a signal in the first frequency band to the second transceiver.
