摘要： Apparatuses and methodologies are described that enhance performance in a wireless communication system using beamforming transmissions. According to one aspect, a set of transmit beams are defined that simultaneously provides for space division multiplexing, multiple-input multiple output (MIMO transmission and opportunistic beamforming. The addition of a wide beam guarantees a minimum acceptable performance for all user devices.

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。
