20130090115 | METHODS AND APPARATUS FOR INTELLIGENT INITIATION OF CONNECTIONS WITHIN A NETWORK - 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. | 04-11-2013 |
20130210420 | METHODS AND APPARATUS FOR IMPROVING POWER CONSUMPTION IN A WIRELESS NETWORK - 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. | 08-15-2013 |
20130244590 | Apparatus and methods for mitigating protocol-induced back-offs in a communication network - 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. | 09-19-2013 |
20130244719 | METHODS AND APPARATUS FOR PARAMETER ADJUSTMENT DURING MEASUREMENT GAPS - 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.). | 09-19-2013 |
20130267232 | APPARATUS AND METHODS FOR RESOLVING INCOMPLETE MESSAGE CONTENT IN NETWORKS - Methods and apparatus for resolving incomplete message content in networks. Various embodiments of the present disclosure are directed to correction and recovery of incomplete measurement report configuration messages within a Long Term Evolution (LTE) network. Specifically, within certain LTE networks, existing messaging may be incomplete in regards to various nearby ancillary networks, but still sufficient with regards to measurement requirements of the LTE network itself. Since the mobile device can continue operation within the LTE network, the mobile device can safely ignore or correct the measurement report configuration message. | 10-10-2013 |
20130329631 | METHODS AND APPARATUS FOR ENHANCED TRANSMIT POWER CONTROL - 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. | 12-12-2013 |
20140106810 | Method and Apparatus to Improve the Robustness of a Wireless Communication Link - 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. | 04-17-2014 |
