Description

一种指示和接收上行波束索引的方法、 ***及装置 技术领域
本发明涉及移动通信领域， 尤其涉及一种指示和接收上行波束索引的方 法、 ***及装置。 背景技术
在高频通信时， 由于釆用了更高的载波频率进行传输， 平均的路损会比传 统的 LTE***大很多， LTE***最高要求达到覆盖 100km的区域，如果按照最 高覆盖， 仅仅考虑平均路损那么高频通信最高可以覆盖达到 lkm的区域， 如果 考虑实际高频载波的高空气吸收度、 以及对于阴影衰落敏感等特点， 实际支持 的覆盖要小于 lkm。 如果高频通信支持最大 lkm覆盖， 与 LTE***相比， 相同 的覆盖区域可以获得的 SINR比不同，前者比后者存在至少 20dB的信噪比下降。 为了保证高频通信与 LTE***覆盖范围内具有近似的 SINR， 需要保证单位面 积上容纳更多的天线。
更多的天线意味着我们可以釆用波束赋型的方法来保证高频通信的覆盖。 由 LTE先前的设计思想可知， 要想得到好的波束赋型效果需要准确的获得信道 的状态信息， 从而从信道的状态信息中获得波束赋型的权值。 而获得较好的波 束赋型权值， 对于发送端基站来说， 接收端终端需要反馈下行的信道状态信息 或者权值； 对于接收端来说， 发送端基站需要反馈上行的信道状态信息或者权 值， 从而保证基站可以釆用最优的波束发送下行业务， 终端也可以釆用最优的 波束发送上行业务。 基站在获得权值前， 无法利用最优的波束覆盖到接收端， 从而接收端无法测量基站发送的参考信号， 或者即使基站覆盖到终端， 但是终 端无法达到基站的同样的覆盖， 反馈的内容基站无法获知， 从而也不能进行波 束权值的选择和正常通信。 发明内容
