    摘要： A method and system for closed loop power control in a wireless communication network. A received signal is despread. The signal power of the despread received signal is estimated. The noise power of the despread received signal is estimated. Estimating the noise power includes multiplying the despread received signal with an orthogonal noise code to cancel the received signal, accumulating the multiplied despread received signal over one frame and determining a signal-to-noise ratio of the received signal at least in part by dividing the estimated signal power by the estimated noise power. A reverse power control bit is determined based on the determined signal-to-noise ratio.

    摘要： A method and apparatus is provided for assigning resources for an acknowledgement channel, such as the PHICH in LTE systems. A list of acknowledgement channels for a group of scheduled mobile terminals is generated. The list is sorted in descended order of the required transmit energies for the corresponding mobile terminals. The acknowledgement channels are then assigned to channel groups one at a time in sorted order to an available channel group with the lowest cumulative transmit energy. By sorting the channel list before assigning resources, the variance in the transmit energies for different channel groups is reduced. Given enough number of acknowledgement channel groups, the small variance in the transmit energies for different channel groups implies improved error rate performance.

    摘要： A radio resource management method is provided. Data for transmission is stored. The stored data is associated with user equipment (UE). A channel quality is estimated. A first modulation and coding scheme (MCS) is determined based at least in part on the estimated channel quality. A first number of scheduling blocks (SBs) required to transmit the stored data is determined based at least in part on the first MCS. The first number of SBs are a minimum of an initial number of SBs and available amount of SBs. A link quality is calculated based at least in part on a channel condition associated with the first number of SBs. A second MCS is determined based at least in part on the calculated link quality and a link quality requirement.
