摘要： A method for power control in a wireless communication system. An initial transmission of a data frame in the reverse link is received, and a first energy level of the data frame is measured. An energy deficit in the first energy level is then measured if the first energy level is insufficient to correctly decode the data frame, so that when the data frame is retransmitted with a second energy level equal to a difference between the first energy level and the energy deficit, the data frame can be correctly decoded with combined energy of the first energy level and the second energy level.

摘要： Techniques to implement MBMS services in a wireless communication system. In one aspect, a method is provided for p8rocessing data for transmission to a plurality of terminals. Frames of information bits (which may have variable rates) are provided to a buffer implementing a matrix. The matrix is padded with padding bits based on a particular padding scheme to support variable frame rates. The frames are then coded based on a particular block code to provide parity bits. The frame of information bits and the parity bits are then transmitted to the terminals. In another aspect, a method is provided for controlling the transmit power of a data transmission to a plurality of terminals. In accordance with the method, TPC streams are received from the terminals and processed to obtain a stream of joint power control commands used to adjust the transmit power of the data transmission.

摘要： Uplink power control is provided to maintain the integrity of the uplink HS-DPCCH when the UE goes into SHO. The target pilot SNR threshold is controlled by considering the pilot signal strength of the serving Node-B and/or the uplink channel condition of the serving Node-B when deciding to increase or decrease the target pilot SNR threshold of Nodes-B.

摘要： In accordance with an exemplary embodiment of the invention, an apparatus, system, and method efficiently manage reverse link resources by allowing a mobile station to select between transmitting a payload a standard power level and transmitting a smaller payload at a boosted power level. The mobile station, therefore, can autonomously select a QoS (Quality of Service) level for physical layer packets. Based on reverse link transmission information received from a base station, the mobile station derives a reverse link transmission guideline defining the power levels and associated payloads for at least a standard service and boosted service. The mobile station selects a reverse link transmission power level from a plurality of power levels including at least a standard reverse link transmission power level associated with a standard payload size and a boosted reverse link transmission power level associated with a boosted payload size where the standard payload size is greater than the boosted payload size.

摘要： The present invention is a novel and improved method and system for performing the pilot frequency tracking operation for coherent demodulation in a system employing a gated pilot signal. In particular, the present invention describes a method and apparatus in which two frequency tracking loops operate in parallel. The first frequency tracking loop performs its tracking operation based on the hypothesis that the received pilot is continuous throughout the frame's duration. The second frequency tracking loop performs the tracking operation based on the hypothesis that the received pilot is discontinuous and is only present for a portion of the frame's duration.
