    • PROBLEM TO BE SOLVED: To disclose a method for transmitting channel quality information based on a differential scheme. SOLUTION: When channel quality information for a predetermined number of sub-bands selected by a receiver in a frequency selective channel is transmitted, total average channel information is transmitted. The channel information for the selected predetermined number of sub-bands is transmitted, as sub-band differential information associated with average channel information. In this case, the sub-band differential information can be denoted by a specific value, within a difference-value range, having only positive values. When two or more pieces of channel quality information are transmitted by a multiple antenna system, channel quality information for one channel is transmitted, and the channel quality information for the other channel is transmitted as spatial differential information. Here, the spatial differential information is transmitted as a specific value within a difference-value range set so as to have a range which is asymmetric about "0" as a center.

    • 要解决的问题:公开一种基于差分方案来发送信道质量信息的方法。 解决方案:发送由频率选择信道中的接收机选择的预定数量的子频带的信道质量信息时,发送总平均信道信息。 作为与平均信道信息相关联的子带差分信息,发送所选择的预定数量的子带的信道信息。 在这种情况下,子带差分信息可以在仅具有正值的差值范围内的特定值表示。 当通过多天线系统发送两条或多条信道质量信息时,发送用于一个信道的信道质量信息,并且作为空间差分信息发送用于其他信道的信道质量信息。 这里,将空间差分信息作为特定值发送到设定的差值范围内,使得以“0”为中心的非对称范围。 版权所有(C)2010,JPO&INPIT

    • PURPOSE: A method for transmitting channel quality indicator is provided to improve the system performance by minimizing the performance degradation of a scheduler. CONSTITUTION: A signal is received through a plurality of legacy system bands. The CQI(Channel Quality Indicator) about a plurality of legacy system bands uses the CQI transmission mode which is similar to each legacy system for each bandwidth. In case each legacy system for each bandwidth CQI is transmitted through the uplink shared channel, each legacy system for each bandwidth CQI whole is transmitted. In case each legacy system for each bandwidth CQI is transmitted through the uplink control channel, each legacy system for each bandwidth CQI is successively transmitted to the fixed number unit.
    • 目的:提供一种传输信道质量指标的方法,通过最小化调度器的性能下降来提高系统性能。 构成:通过多个遗留系统频带接收信号。 关于多个传统系统频带的CQI(信道质量指示符)使用与每个传统系统相似的每个带宽的CQI传输模式。 在通过上行链路共享信道发送每个带宽CQI的每个传统系统的情况下,传送每个带宽CQI整体的每个遗留系统。 在每个带宽CQI的传统系统通过上行链路控制信道发送的情况下,每个带宽CQI的每个传统系统被连续发送到固定数量单元。

    • PROBLEM TO BE SOLVED: To provide a channel coding method of variable length information using a preferred block code.SOLUTION: The channel coding method for channel-coding information bits using a code generation matrix including 20 rows and A columns corresponding to length of the information bits includes channel-coding the information bits having "A" length using basis sequences having 20-bit length corresponding to each column of the code generation matrix. When "A" is 10, respective basis sequences of the code generation matrix correspond respectively to column directional sequences of the matrixes composed of 20 rows comprised by selecting 20 rows from the code matrix composed of 32 rows and 10 columns which are used for TFCI (Transport Format Combination Indicator) information coding and 10 columns.
