摘要： A communications device synchronizes itself with respect to an external reference signal, e.g., a GPS signal. The communications device detects timing reference signals, e.g., beacon signals, from a communications network. If the communications device determines that the network is not synchronized to the external timing reference signal, the communications device operates as a master timing control device. In various embodiments, when operating as a master timing control device the wireless communications device communicates time stamps, e.g., in beacon signals, which indicate a greater passage of time than the actual passage of time. When operating as a master timing control device the communications device transmits network timing reference signals at a higher rate than is being used by the network to seize control of network timing and become the master timing control device. The communications device drives the network timing to synchronize network timing to the external timing reference.

摘要： Systems and methodologies are described that facilitate integrating a list-sphere decoding design in a multiple input-multiple output (MIMO wireless communication environment. According to various aspects, optimal rank selection and CQI computation for an optimal rank can be performed in conjunction with a non-linear receiver, such as a maximum life (ML) MMSE receiver, a non-linear receiver with a list-sphere decoder, and the like. Optimal rank selection can be performed using a maximum rank selection protocol, a channel capacity-based protocol, or any other suitable protocol that facilitates rank selection, and CQI information can be generated based in part on effective SNRs determined with regard to a selected optimal rank.

摘要： The scheduler in a base station needs CQI information from a terminal for all re-use sets every 5 ms. to decide on which re-use set to schedule a given terminal. For MIMO users, the problem is that the CQI cannot be reconstructed for all re-use sets, using the current design. Solution: (1) For Multiple Code Word MIMO users, a MIMO VCQI connection layer message enables the base station to reconstruct the MIMO-CQI for all reuse sets on a packet-by-packet basis. This will enable dynamic scheduling (RESTRICTIVE REUSE) gains. (2) For Single Code Word users, dynamic RESTRICTIVE REUSE can be obtained by changing the CQI reporting format, and also sending a MIMO-VCQI connection layer message. (3) For Single Code Word design, quasi-static scheduling gains can be obtained by sending a MIMO-VCQI connection layer message.
摘要翻译：基站中的调度器每5ms需要来自终端的所有重用集合的CQI信息。决定哪个重用设置来安排一个给定的终端。对于MIMO用户，问题在于，使用当前设计，不能为所有重用集合重建CQI。解决方案：（1）对于多码字MIMO用户，MIMO VCQI连接层消息使得基站能够逐个分组地重建所有重用集合的MIMO-CQI。这将使动态调度（限制性重用）获益。（2）对于单码字用户，可以通过改变CQI报告格式，并发送MIMO-VCQI连接层消息来获得动态限制重用。（3）对于单码字设计，可以通过发送MIMO-VCQI连接层消息来获得准静态调度增益。
