專利摘要(中)
一種天線陣列的波束調準方法,包括下列步驟:基地台 採用多組多峰波束樣式作為傳送數個同步訊號之波束樣式;用戶 設備掃描同步訊號,並判斷接收功率最強的同步訊號及其所對應 的接收波束方向,並藉由隨機接取通道傳送包括(明示或暗示)最強 同步訊號之索引資訊的初始接取訊息;基地台在隨機接取通道上 採用多組單峰波束樣式接收初始接取訊息,並判斷對初始接取訊 息之接收功率最強的單峰波束樣式,以將其與初始接取訊息中的 該接收功率最強的同步訊號之索引資訊所對應的多峰波束樣式的 主波束進行比對,以確定傳送給用戶設備的最佳波束方向 。
專利摘要(英)
A beam alignment method for an antenna array is provided. In the method, a base station adopts a plurality of multi-modal beam patterns as beam patterns for transmitting synchronization signals. A user equipment scans the synchronization signals, determines the synchronization signal with strongest received power and a receive 第2頁,共 2 頁(發明摘要) beam direction corresponding thereto, and transmits an initial access message including an index information explicitly or implicitly indicating the strongest synchronization signal through a random access channel. The base station receives the initial access message on the random access channel by using a plurality of single-modal beam patterns, determines the single-modal beam pattern with a strongest access power for the initial access message, and determines an optimal beam direction for the transmission to the user equipment by comparing the determined single-modal beam pattern with the strongest access power and a main lobe of the multi-modal beam pattern corresponding to the index information included in the initial access message.
