Abstract: Methods and apparatus for improved power control in communications (such as connection establishment) in a wireless network, in one embodiment, a data-based, iterative approach is used to select an appropriate transmission power level during the establishment of a wireless connection. An assessment of the quality of the channel between a connecting device and target device is made, based on a received reference signal from the target device. The assessment is used to select an initial power level for a random access request. In the case a response is not received, a subsequent assessment of the channel quality is made. If the quality of the channel has changed, then a second power level for a second random access request is selected. This approach allows the connecting device to adapt to changing conditions related to the channel quality, and adjust its transmission power level accordingly.

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: An electronic device may contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. The electronic device may use the multiple antennas to make received signal power measurements. The signal power measurements may be made for each frequency in a list of frequencies used most recently by the electronic device in conveying data traffic between the electronic device and a wireless network. Based on received signal power measurements, the electronic device may select which frequency to use in performing system acquisition operations to attempt to establish a wireless communications link between the electronic device and the wireless network. The device may make signal power measurements for each antenna in the device to determine which antenna should be used in performing the system acquisition operations or may rotate through antennas in sequence to identify an antenna that can successfully perform system acquisition operations.

Abstract: Methods and apparatus enabling connection and/or re-connection to an access point of a network based on both reception characteristics and also the access point's likelihood to successfully connect (or re-connect). In one such embodiment, an exemplary Long Term Evolution (LTE) user equipment (UE) stores a "blacklist" of LTE enhanced NodeBs (eNBs) that have previously unexpectedly disconnected the UE. The UE will avoid the blacklisted eNBs and will attempt to connect to other eNBs. By avoiding eNBs which have previously been unable to service the UE and instead focusing on other eNBs that may have lower reception quality but likely better suited to service the UE, the UE can avoid prolonged out-of-service (OOS) periods.

Abstract: Methods and apparatus for mitigating data server time-outs in e.g., a hybrid wireless network. In one exemplary embodiment, a client device operating in a hybrid network environment utilizes its knowledge about tune-away periods so as to minimally affect data network operation. For example, during periods of data downlink activity, the client device induces some delay in the acknowledgement packets sent back towards the network prior to entering into a tune away period. These delayed acknowledgement packets result in an increased retransmission time out period value thereby reducing the probability of encountering a data server time-out. Alternative embodiments are also discussed which preoccupy the network apparatus during these tune away periods so as to also mitigate time-outs during these periods. These mitigation algorithms are useful in both downlink and uplink data transmissions. Apparatus for implementing these methodologies are also disclosed.

Abstract: A method for reducing call drops in uplink power limited scenarios is disclosed. The method can include a wireless communication device determining that the wireless communication device is experiencing an uplink power limited condition in which a transmission power of the wireless communication device is limited to a level below a power class level of the wireless communication device. The method can further include defining a downlink power threshold for sending a measurement report for triggering a handover based on the uplink power limited condition. The downlink power threshold can be higher than a threshold configured by a serving base station. The method can additionally include determining based on measured downlink power that the calculated downlink power threshold is satisfied and sending a measurement report for triggering a handover to the serving base station in response to the downlink power threshold being satisfied.
