Abstract: Aspects of the methods and apparatus relate to improving the overall decision quality of the Fractional-Dedicated Physical Channel (F-DPCH) channel. One aspect of the methods and apparatus relates to detecting bad channel conditions of a serving base station and improving the serving base station F-DPCH decoding performance in such bad conditions based on the serving base station signal-to interference ratio (SIR) estimation. Another aspect of the methods and apparatus relate to improving the overall decision quality of the F-DPCH channel in soft handover (HO) scenarios by increasing the non-serving base station F-DPCH channel rejections thresholds based on certain SIR estimations. The F-DPCH channel rejections thresholds are based on either the SIR of the non-serving base station, or a difference between non-serving base station SIR and serving base station SIR.

Abstract: Methods and devices for improving performance on a wireless communication device having at least a first subscriber identity module (SIM) and a radio frequency (RF) resource may include detecting, on a modem stack associated with the first SIM, an active communication in a first network that supports high speed downlink packet access (HSDPA). During the active communication in the first network, the wireless communication device may detect a signal disruption period, and determine whether an operational downlink mode for the modem stack associated with the first SIM does not match a corresponding downlink mode represented in the first network. Upon determining that the operational downlink mode for the modem stack associated with the first SIM does not match the corresponding downlink mode represented in the first network, the wireless communication device may trigger an internal instruction to transition to a new downlink mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, while camped on a first cell associated with a first radio access technology (RAT), a power management level for a communication using a second RAT, wherein the power management level indicates an available power for the communication using the second RAT, and wherein the available power is based at least in part on an exposure rate or an absorption rate. The UE may delay a transmission of a measurement report on the first cell based at least in part on the identification of the power management level. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mechanisms for detecting and skipping cells a UE is not able to camp on (e.g., NSA cells) during a cell selection procedure. As a result of the skipping, a UE may be able to more quickly detect and select a cell (e.g., an SA cell) that the UE is able to camp on, thus leading to better user experience.

Abstract: Various embodiments for managing carrier transmissions after a tune-away on a wireless communication device may include determining whether a network has received transmissions from a first carrier of a first subscription after completion of the tune-away from the first subscription to a second subscription. In response to determining that the network has not received transmissions from the first carrier, the wireless communication device may determine whether a second carrier of the first subscription is transmitting to the network after completion of the tune-away. In response to determining that the second carrier is not transmitting to the network, the wireless communication device may route transmission from the first carrier to the second carrier.

Abstract: Apparatus and methods of receive diversity (RxD) full cell search by a user equipment (UE) in a wireless communication system are described. In an aspect, a first set of received energies of a first signal received at a first antenna and a second set of received energies of a second signal received at a second antenna may be separately determined. Based thereon, a set of peak energies and corresponding antenna indices, along with a slot timing of at least one cell corresponding to the set of peak energies and corresponding antenna indices, may be determined. A frame timing and a scrambling code for the at least one cell then may be determined using a respective one of the first antenna and the second antenna corresponding to each of the set of peak energies and the corresponding antenna indices, along with the respective slot timing of the at least one cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may allocate a first amount of power to one or more radios for a time window based on radio frequency (RF) exposure information and one or more other criteria. The UE may allocate a second amount of power to a selected channel or communication utilized by at least one radio of the one or more radios for one or more time frames within the time window based on the first amount of power allocated to the at least one radio for the time window. The UE may transmit the selected channel or communication based on the first amount of power or the second amount of power. Numerous other aspects are described.
