Abstract: A method of wireless communication includes returning to a base station after a handover failure. The method also includes measuring a length of time between receiving a handover command and returning to the base station. The method further includes setting a physical uplink channel transmit power based on the measured length of time. The physical uplink channel can be an enhanced physical uplink channel (E-PUCH) of a high speed uplink packet access (HSUPA) wireless network.

Abstract: A method of wireless communication includes determining whether a serving cell signal strength is below a first threshold. The method also includes determining whether an inter/intra frequency neighbor cell signal strength is below a second threshold. The method further includes determining whether a number of idle traffic time slots for inter-radio access technology IRAT measurements is less than a third threshold. Finally, a frequency of IRAT measurements in time slot zero (TS0), a downlink pilot time slot (DwPTS), an uplink pilot time slot (UpPTS), and a gap (GP) is increased. The increase is based on the determined serving cell signal strength, the determined inter/intra frequency neighbor cell signal strength, and the determined number of idle traffic time slots.

Abstract: Methods for improving the time to acquire an identity of a base station by a mobile station, by relying on locally-unique attributes of the base stations instead of globally-unique attributes of the base stations, are presented. In some embodiments, data may be requested, the data may contain a globally unique attribute of a base station, a first locally unique attribute of the base station, and a second locally unique attribute of the base station. In some embodiments, data may be received in response to the request, the data may contain at least the first locally unique attribute and the second locally unique attribute. It may then be determined that the data did not contain the globally unique attribute, and an identity of the base station based at least in part on the first locally unique attribute and the second locally unique attribute may be acquired.

Abstract: A user equipment (UE) dynamically adjusts a decoding time to accommodate a delay associated with decoding a high-speed shared control channel (HS-SCCH) to avoid wasting idle time slots that would otherwise be deemed busy time slots. The UE determines a dynamic protection line that extends beyond a last time slot of a subframe. The dynamic protection line is calculated based on an amount of time to complete the processing and decoding of a control information. This dynamic protection line provides a dynamically determined delay for decoding the HS-SCCH.

Abstract: Apparatus, methods, and computer-readable media for facilitating managing multi-SIM concurrent mode for TDD co-banded or spectrum overlap carriers are disclosed herein. An example method for wireless communication at a user equipment (UE) includes estimating a maximum transmit power for a first subscriber based on a low-noise amplifier (LNA) input power threshold associated with an active receive chain of a second subscriber, where the UE comprises the first subscriber and the second subscriber. The example method also includes transmitting, via an active transmit chain of the first subscriber, an uplink transmission at the first subscriber maximum transmit power based on the first subscriber and the second subscriber operating concurrently, and a transmit power associated with the uplink transmission being greater than the first subscriber maximum transmit power.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, via a first subscription of the UE, a trigger event for a conditional handover of the UE from a source network entity to a target network entity. The UE may determine, based at least in part on the trigger event, that a target band associated with the target network entity is not compatible with a serving band associated with a second subscription of the UE. The UE may store the trigger event for the conditional handover in a buffer of the UE. The UE may perform an action related to the conditional handover based at least in part on a condition being satisfied. Numerous other aspects are described.
