    • A method of and an apparatus for reducing the average power consumption in a remote unit in a wireless communication system. When a remote unit in a slotted mode communication system receives a general paging massage, it deinterleaves and decodes the raw data samples. Prior to parsing, it compares the decoded data samples with samples stored in a memory. Based on this comparison, the remote unit determines whether or not the message is empty. If the message is empty, the remote unit transitions to an inactive state. By comparing before parsing, the remote unit is able to conserve power by entering the inactive state sooner. If no samples are stored in the memory, instead of comparing, the remote unit parses the message and executes any instructions. If, upon parsing, the remote unit determines the message to be empty, at least a portion of the message is stored in the memory.
    • 一种用于降低无线通信系统中的远程单元的平均功耗的方法和装置。 当时隙模式通信系统中的远程单元接收到一般的寻呼按摩时,它对原始数据样本进行解交织和解码。 在解析之前,它将解码的数据样本与存储在存储器中的样本进行比较。 基于该比较,远程单元确定消息是否为空。 如果消息为空,则远程单元转换到非活动状态。 通过在解析之前进行比较,远程单元能够更快地进入非活动状态来节省功率。 如果没有样本存储在存储器中,而不是比较,远程单元解析消息并执行任何指令。 如果在分析时远程单元确定消息为空,则消息的至少一部分被存储在存储器中。

    • STTD encoding is signal processing carried out when a base station performs diversity transmission in open-loop mode to a mobile station. The STTD encoding method according to the present invention applies reverse STTD encoding on a pilot signal that should not be subjected to STTD encoding beforehand. Then, the multiplexer time-multiplexes the pilot signal with transmission data and control data to compose a transmission frame. Then, all data included in the transmission frame is subjected to STTD encoding. Applying reverse encoding before frame composition eliminates the need for distinguishing data to be encoded from data not to be encoded during STTD encoding.
