    Abstract: Methods and apparatus to manage communication sessions to handover between a direct connection at a secondary wireless device and a relayed connection to the secondary wireless device via a primary wireless device. A connection manager of a secondary wireless device can trigger transfer of a communication session based on measurements of performance metrics for the communication session. Upon detection of performance degradation in a local connection or a backhaul connection or both, the connection manager of the secondary wireless device can determine proximity of and/or capabilities for connections of the primary wireless device and instigate transfer of the communication session between different connection types, such as between a direct connection and a relayed connection. The transfer of the communication session can occur without user intervention or in response to input from the user without interrupting or reestablishing the communication session.

    Abstract: A jitter buffer in a Voice over LTE receiver may be influenced by radio level feedback (RLF) from both local and remote endpoints to preemptively adjust the jitter buffer delay in anticipation of predicted future losses that have a high probability of occurring. The radio events of the RLF and the scenarios that trigger the preemptive adjustments may be identified, and their use may be expressed in terms of mathematical formulas. In prior art designs, the instantaneous jitter is derived from a weighted history of the media stream, and consequently only packets that have already arrived are used to compute the instantaneous jitter to adjust the length of the buffer. By providing and using RLF from both local and remote endpoints, the anticipated delay - for packets that have not yet arrived - may be used to preemptively adjust the buffer, thereby minimizing packet loss without introducing unnecessary delay.

    Abstract: Methods and apparatus for power optimization in e.g., a wireless mobile device. In one embodiment, the optimization is effected via intelligent idle mode current drain management. In an exemplary LTE cellular network context, the user equipment (UE) only powers on its transceiver for a subset of Discontinuous Reception (DRX) cycles based on e.g., the quality of the radio environment, power considerations, location, etc. For example, if a UE has not moved, and its radio reception quality is good, the UE is likely to successfully receive a paging notification (i.e., without multiple attempts). Consequently, the UE configures itself to receive only a single paging indication.

    Abstract: A method and apparatus to improve the robustness of a wireless communication link between a base station and a mobile communication device. The method increases power selectively on portions of an uplink communication signal transmitted from the mobile communication device to the base station. The method monitors a quality metric value at the mobile communication device and sets the transmit power level of the first portion of an uplink communication signal to the first power level, if the monitored quality metric value is in a first range of quality values, or sets the transmit power level of the first portion of the uplink communication signal to a second power level, if the monitored quality metric value is in a second range of quality values. The first portion of the uplink communication signal includes control signals used by a base station to maintain connection of the wireless communication link.

    Abstract: Methods and apparatus for parameter (e.g., timing) adjustment in a wireless network. In one embodiment, the timing adjustment includes detection and compensation for one or more missed adjustment messages. In one variant, for certain designated events, a client device may ignore a timer expiration, and apply a previously stored timing advance (TA) command. For example, a user equipment (UE) will determine if a TA command has been missed during a measurement gap interval (such as e.g., to perform measurements on an unsynchronized network), and reuse the previous TA command value. Reusing the TA command value introduces negligible error, which can be corrected in existing error correction capabilities (e.g., OFDM cyclic prefixes, etc.).

    Abstract: A station that generates data packets to be transmitted such that the data packets spend a minimum amount of time in a buffer prior to transmission. The method includes receiving a specification for a connected discontinuous reception (C-DRX) cycle that indicates when a plurality of on Durations of the C-DRX cycle occurs, the on Durations having a predetermined interval therebetween, receiving data at a known time relative to the C-DRX cycle, determining a modification to a conversion process that converts the data to data packets such that the data packets are stored in a buffer at a subframe immediately preceding one of the on Durations subsequent to the known time, performing the conversion process based upon the modification and storing the data packets at the subframe immediately preceding the one of the on Durations. In one embodiment, the data is raw audio data and the data packets are audio packets.
