    Abstract: A method for transmitting data in a multiple-input-multiple-output space-time coded communication using a mapping table mapping a plurality of symbols defining the communication to respective antennae from amongst a plurality of transmission antennae and to at least one other transmission resource. The mapping table may comprise Alamouti-coded primary segments and may also comprise secondary segments, comprising primary segments. The primary segments in the secondary segments may be defined in accordance to an to Alamouti based code pattern applied at the segment level to define a segment-level Alamouti based code.

    Abstract: Transmission of uplink control message for a wireless system. The uplink control message may be encoded according to one of multiple possible schemes. The choice of encoding scheme may be made based on the control message size and/or based on the available transmission resources and/or based on the detection scheme used on the receiving end. A modulation scheme may also be selected based on such factors. CDM may be used for certain control messages. Block code encoding, such as Reed-Muller encoding may be used for certain control messages. Different transmission resources may be allocated for different control message uses. The encoding specifics may be selected to obtain a certain hamming distance and/or size of the encoded message or based on other factors.

    Abstract translation: 传输无线系统的上行链路控制消息。 上行链路控制消息可以根据多种可能方案之一进行编码。 可以基于控制消息大小和/或基于可用传输资源和/或基于在接收端使用的检测方案来进行编码方案的选择。 还可以基于这样的因素来选择调制方案。 CDM可以用于某些控制消息。 块代码编码,如Reed-Muller编码可用于某些控制消息。 可以为不同的控制消息使用分配不同的传输资源。 可以选择编码细节以获得编码消息的某个汉明距离和/或尺寸,或者基于其他因素。
