傳輸導頻序列的方法和裝置制造方法及圖紙

本發明專利技術公開了一種傳輸導頻序列的方法和裝置，通過終端設備確定第一導頻編號，根據該第一導頻編號確定第一導頻序列和第二導頻序列，并將該第一導頻序列和該第二導頻序列分別映射到免授權傳輸資源的第一OFDM符號和第二OFDM符號，再通過該第一OFDM符號和該第二OFDM符號，發送該第一導頻序列和該第二導頻序列，使得網絡設備通過對第一導頻序列的檢測，可以確定終端設備的活躍性，并由此可以僅僅對與第一導頻序列相應的第二導頻序列進行檢測，而不用對所有可能的第二導頻序列進行檢測，由此能夠顯著地減少導頻檢測數量，降低導頻檢測的復雜度。

Method and device for transmitting pilot sequence

The invention discloses a method and a device for transmitting pilot sequence, determine the first pilot number through the terminal equipment, according to the first pilot number to determine the first pilot sequence and second pilot sequences, and the sequence of the first pilot and second pilot sequences were mapped to the first OFDM symbol and OFDM symbol second without authorization of the transmission resources, and then through the first OFDM symbol and the second OFDM symbol, transmits the first pilot sequence and the second pilot sequence, so that the network equipment through the detection of the first pilot sequence, can determine the activity of the terminal equipment, and thus can only detect the first pilot sequence the second pilot sequences, instead of all possible second pilot sequences were detected, which can significantly reduce the number of pilot testing, reduce the complexity of pilot testing.
