Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate via a first connection using one or more transmit parameters. The UE may determine to suspend subsequent attempts to communicate via a second connection, in a dual connection mode, based at least in part on satisfaction of a threshold number of failed attempts to communicate via the second connection. The UE may determine one or more parameters for suspension of the subsequent attempts to communicate via the second connection based at least in part on a determination that satisfaction of the threshold number of failed attempts is associated with one or more exposure conditions that are based at least in part on the one or more transmit parameters. Numerous other aspects are provided.

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: 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: 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: The disclosure provides for reporting a channel quality indicator (CQI) in wireless communications. A user equipment (UE) may determine that a calculated CQI value to be reported in a current sub-frame is affected by a deterministic null scheduling on a downlink channel. The UE may determine a compensatory CQI value. The UE may report the lesser of the calculated CQI value and the compensatory CQI value in response to determining that the calculated CQI value is affected by the deterministic null scheduling. In an aspect, the deterministic null scheduling is associated with a compressed mode gap. The UE may determine whether the calculated CQI value is affected by the deterministic null scheduling by determining whether the current sub-frame is within a first time period before the start of the compressed mode gap or within a second time period after the end of the compressed mode gap.

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.
