Title:
SIGNAL TRANSMISSION METHOD, RECEIVING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/137669
Kind Code:
A1
Abstract:
Disclosed are a signal receiving method, a transmission method and a device, relating to the field of communications, and solving the problem of a small number of UEs supporting orthogonal code division multiplexing by means of a cyclic shift when a frequency deviation existing between a central frequency for a UE to receive a signal and a central frequency for a base station to transmit a signal is comparatively greater than a sub-carrier interval used for communication between the base station and the UE. The specific solution involves: a base station determining a target root indicator from a sequence indicator set, wherein the sequence indicator set is {A1, B1, A2, B2,..., As, Bs}, Ai = i (mod K), Bi = -i (mod K), Ai and Bi are root indicators of a Zadoff-Chu (ZC) sequence, i is an integer greater than or equal to 1 and less than or equal to s, s is an integer greater than or equal to 1 and less than or equal to the LＫ/2」 - １, L 」 represents an integer rounded down, and K is the length of the ZC sequence; the base station generating a signal sequence according to the target root indicator; the base station receiving an uplink signal; and the base station processing the uplink signal according to the signal sequence. The embodiments of the present invention are used in a signal transmission process.
