Abstract: The present disclosure is directed to methods and apparatuses for increasing throughput of WLANs using queue size based intelligent reverse direction grants (RDGs). RDGs have been introduced in many WLANs to reduce the amount of overhead associated with variants of the CSMA/CD MAC protocol. Reducing overhead increases the WLANs achievable data throughput. However, RDGs are not intelligently used in WLANs, limiting their effectiveness.

Abstract: A method and system are provided in which a mobile device may be operable for long term evolution (LTE) communication or some other wireless technology via two or more transmit antennas. The device may comprise a power amplifier for each transmit antenna with substantially similar maximum power being provided by both amplifiers. A power headroom value may be determined in the device based on path loss values between the transmit antennas and a base station and the maximum transmit power for each transmit antenna. Transmission via one of the transmit antennas may occur concurrently with transmission via another of the transmit antennas. The device may generate an indication of the determined power headroom value for communication to the base station. The power headroom value may be reported periodically or in response to a change in the power received at the base station.

Abstract: A method and apparatus of selecting which of a plurality of receiver chains of a mobile unit to receive wireless signals, is disclosed. One method includes measuring a first receive signal quality while all of the plurality of receiver chains are receiving wireless signals, and measuring a second receive signal quality while a subset of the plurality of receiver chains are receiving wireless signals. The subset of the plurality of receiver chains are selected to receive wireless signal unless the first receive signal quality is a threshold better than the second receive signal quality. If the first receive signal quality is a threshold better than the second receive signal quality then all the plurality of receiver chains are selected to receive wireless signals.

Abstract: A wireless communication device is disclosed that is capable of reduced power consumption. Uplink and downlink sub-frames in a WiMAX, 802.16m or LTE environment often include several vacant symbols during which power-hungry hardware and software components need not operate at full power. By analyzing a physical layer beacon and control information of a received signal, the specific locations of data bursts can be determined, as well as periods of needed operation of a receiver module to effectively decode those data bursts. The receiver module can otherwise be controlled to operate in a LOW power state during remaining periods of vacant time, thereby conserving power consumption and extending battery life.

Abstract: A wireless communication device is disclosed that is capable of performing efficient handoffs in order to maximize connection time with either a serving or target base station. The wireless communication device performs measurements of only intra-frequency base stations to avoid retuning its radio module. Based on this information, as well as stored information relating to nearby base stations, the serving base station is able to estimate a position of the wireless communication device and compare the estimated position to positions of the known base stations in order to make a handoff decision. In addition, by storing information during measurement or handoff preparation, the device is capable of skipping handoff steps, immediately return to the serving base station after handoff failure, and/or perform streamlined PLMN searching.

Abstract: Methods of allocating a plurality of periodically distributed frames of communication between a first wireless transceiver and a second wireless transceiver are disclosed. One method includes detecting periodic data for transmission between the wireless base station and the wireless mobile unit. A transmission map that maps frequency and time slots is generated for transmission of the data packets. Allocation information is included within less than all of a plurality of transmission maps of the plurality of periodically distributed frames, The allocation information designates frequency and time slots in which data packets identified as a periodic data type are transmitted to the second wireless transceiver for the plurality of periodically distributed frames.

Abstract: Systems and methods for regulating transmit power in a mobile station to comply with SAR limits are disclosed. A mobile station may include a processor, transmitter, and proximity sensor. The transmitter is configured to operate at a transmit power controlled by a first transmit power limit. The proximity sensor identifies how close the mobile station is to a human head. A transmit power regulator, implemented on the processor, determines the cumulative energy radiated by the transmitter over a specified number of frames. If the cumulative energy exceeds an energy limit based on a SAR limit, and the proximity sensor indicates that the mobile station is close to a human head, the transmit power regulator may decrease the transmit power limit of the transmitter.

Abstract: Various embodiments of the present invention recognize at least two zones of operation for a communication device. In a first zone, which is sufficiently spaced away from a human head or body that SAR limits will be met, transmit power delivered to an antenna of a communication device may be maximized within any other constraints under which the communication device operates. In a second zone, which is not sufficiently spaced away from a human head or body, transmit power is redistributed such that SAR limitations are met without affecting the transmit power control loop of the communication device. For example, a second antenna physically disposed at a different location within the communication device may be used either instead of, or in addition to, the first transmit antenna in order that the SAR limits are met.

Abstract: A method and apparatus of scheduling and transmitting uplink packets within uplink sub-frames of a wireless system is disclosed. The method includes determining a size of a standard data unit, and determining if the standard data unit can be transmitted within a single sub-channel of an uplink frame by comparing the size of the standard data unit with a number of bits that can be transmitted within the uplink frame as determined by an uplink quality. If the standard data unit is too large to be transmitted within a single sub-channel of an uplink frame, then the standard data unit is divided into sub-data units. The sub-data units are transmitted over multiple uplink frames.
