摘要： A method and apparatus is provided for assigning resources for an acknowledgement channel, such as the PHICH in LTE systems. Acknowledgement channels for the mobile terminals are assigned to channel groups based on a predetermined assignment criteria. All acknowledgment channels in the same channel group receive acknowledgements on the same downlink resources (e.g., resource elements in OFDM system). A required transmit energy for each channel is determined. If the total required transmit energy for all channels exceeds an available transmit power, the allocated transmit energy for each channel is either scaled down so that the total actual transmit power for all acknowledgment channels is equal to the available transmit power, or some acknowledgment channels are not transmitted.

摘要： Methods of performing link adaptation in a wireless communication system for simultaneous transmission of codewords include selecting initial modulation and coding scheme (MCS) levels for the codewords, estimating a size ratio of the codewords, determining a number of scheduling blocks (SB) for the codewords with the initial MCS levels, and determining revised MCS levels for the codewords in response to the determined number of SBs. Transport block sizes are computed for the codewords, and it is determined if there is a need to increase the number of scheduling blocks in at least one of the codewords. If there is a need to increase the number of scheduling blocks in a codeword, scheduling blocks are added to the codeword, and the transport block size for the codeword is recomputed. The codewords are then simultaneously transmitted over different multiple input-multiple output (MIMO) communication channels using the same time and frequency resources.

摘要： A method of paging a mobile terminal in a radio access network wherein the last known location of a mobile terminal is stored. A location message (also called a Route Update message) is sent from a terminal and received at a sector in the network, identifying the location of the terminal. The network determines a paging zone for that terminal based on configuration information for that sector. The configuration information for each sector typically includes a Route Update radius, and then one or both of a paging zone radius offset, and statically configured sectors. When the terminal needs to be paged, the network then broadcasts a page to the terminal in each sector in the paging zone. Such a system adjusts the paging zone to include sectors which the terminal has a reasonable likelihood of moving to before the network learns that the terminal has moved out of the previously established paging zone. Aspects of the invention provide two complementary methods of adjusting the paging zone: adjusting using a paging zone offset, and adjusting based on a sector list. The paging zone offset adjusts the radius of the paging zone, thereby maintaining a generally circular shape. The sector list adjusts the generally circular paging zone by adding or deleting any sector in any direction, thereby allowing any arbitrary shape to be used for the paging zone. The adjustments to the paging zone achieved by these methods account for such factors as RF coverage, geographic features, congestion, population density and expected rate of movement of terminals between sectors.
摘要翻译：一种在无线电接入网络中寻呼移动终端的方法，其中存储了移动终端的最后已知位置。从终端发送位置消息（也称为路由更新消息），并在网络中的扇区处接收，以识别终端的位置。该网络基于该扇区的配置信息确定该终端的寻呼区域。每个扇区的配置信息通常包括路由更新半径，然后包括寻呼区半径偏移和静态配置扇区中的一个或两个。当终端需要被寻呼时，网络然后在寻呼区域的每个扇区中向终端广播一个页面。这样的系统调整寻呼区域以包括终端在网络学习终端已经移出先前建立的寻呼区域之前具有合适的可能性的扇区。本发明的各方面提供了两种调整寻呼区域的补充方法：使用寻呼区域偏移进行调整，以及基于扇区列表进行调整。寻呼区域偏移调整寻呼区域的半径，从而保持大致圆形的形状。扇区列表通过在任何方向上添加或删除任何扇区来调整通常循环的寻呼区域，从而允许任何形状用于寻呼区域。通过这些方法实现的寻呼区域的调整涉及射频覆盖，地理特征，拥塞，人口密度和部门之间终端的预期移动速度等因素。

摘要： An exemplary backlight control circuit (200) includes at least one load circuit (210), a pulse width modulation integrated circuit (250), and a micro controller (260). The micro controller includes an output terminal and a plurality of analog to digital input terminals. The output terminal outputs a high level signal when the analog to digital input terminals all receive high level signals, and the output terminal outputs a low level signal when any one of the analog to digital input terminals receives a low level signal. The micro controller feeds operating states of the at least one load circuit back to the pulse width modulation integrated circuit.
