摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method and apparatus i.e. Base Station for allocating resources in a wireless communication system is provided. The method includes generating a plurality of first groups of allocation units based on one or more of a plurality of Modulation and Coding Schemes (MCSs) and traffic characteristics in the wireless communication system. The method further includes generating a second group of slots including resource allocation information for mapping first groups of allocation units to Mobile Stations (MSs) based on MCSs and traffic characteristics associated with first groups of allocation units and the MSs. Thereafter, the method persistently allocates each first group of allocation units to the MSs based on one or more of the resource allocation information and a communication state associated with each MS. Further, the method also identifies if each MS has succeeded in decoding the persistent resource allocation sent in the second group of slots.
