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: Various embodiments include multi-subscription multi-standby communication devices and methods for managing communication activity. A device processor of the multi-subscription multi-standby communication device may determine a timing of an upcoming tune-away from a first subscription to a second subscription, and may determine whether an upcoming communication activity on the first subscription is a critical communication activity. The device processor may determine whether the upcoming tune-away and the upcoming communication activity will collide in response to determining that the upcoming communication activity is a critical communication activity, and may schedule one or both of the upcoming critical communication activity and the tune-away to prevent the collision in response to determining that the upcoming tune-away and the upcoming communication activity will collide.

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: A method and apparatus for radio resource control (RRC) state transitions of a user equipment (UE) are provided. For the RRC state transitions of the UE, for example, a reconfiguration message is received at the UE while the UE is in a cell dedicated channel (CELL_DCH) state of the RRC states. The reconfiguration message is configured to transition the UE from the CELL_DCH state to a non-dedicated channel state of RRC states. A plurality of acknowledgement procedures is sent on an uplink to the network, in response to the received reconfiguration message causing the UE to transition from the CELL_DCH state to the non-dedicated channel state.

Abstract: Methods and apparatus for communication comprise determining whether a communication characteristic value meets or exceeds a communication characteristic threshold value. Additionally, the methods and apparatus comprise adjusting a retransmission request transmission rate when the communication characteristic value meets or exceeds the communication characteristic threshold value. Moreover, the methods and apparatus comprise sending a retransmission request to a network entity based on the adjusted retransmission request transmission rate.

Abstract: Apparatuses and methods are described herein for managing communications in a wireless communication device, including, but not limited to determining failure to receive a first block, sending a signal as an indication for retransmission of systematic bits instead of sending a negative-acknowledgement (NACK) signal, and receiving a second block including the systematic bits.

Abstract: Disclosed are systems, methods, and computer program products for decoding of transport format combination indicator (TFCI) in a universal mobile telecommunications system (UMTS). In one aspect, a method includes receiving by a UE coded TFCI bit sequence on a physical channel, determining a range of TFCI bits that contain information, performing early decoding of the received TFCI bit sequence; and limiting the search set of decoded TFCI bits to the determined range of TFCI bits. The range of TFCI bits that contain information may be determined from a code book.

Abstract: The present disclosure presents a method and apparatus for reducing power consumption during a voice communication in a user equipment (UE). For example, the method may include receiving a plurality of frames associated with the voice communication. Further, such an example method may include determining whether a frame pattern based at least on the received plurality of frames corresponds to a transition from a speech burst period to a non-speech period, and disabling a portion of a receiver subsystem at the UE for at least a portion of a frame associated with the non-speech period. As such, the power consumption in a UE may be reduced.
