COMMUNICATION METHOD AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/119154

Kind Code:

A1

Abstract:

A communication method and device, comprising: a terminal device generating a reference signal sequence having a length of M, the reference signal sequence being generated by a base sequence having a length of M in a first sequence group allocated to the terminal device, the number of base sequences having a length of M in the first sequence group being X, the ith base sequence in the X base sequences being generated by a ZC sequence having a length N and a root index of qi; when X is an integer greater than or equal to 2, the root index of a first ZC sequence corresponding to any two base sequences among the X base sequences is q, the root index of a second ZC sequence corresponding to any two base sequences is (q+V)mod N, the absolute value of V is an integer greater than or equal to K1 and less than or equal to n-k1, K1 > 1; or, when X is greater than or equal to 3, the root index of the first ZC sequence is q, the root index of the second ZC sequence is (q+V)mod N, the root index of a third ZC sequence that generates a third sequence is (q+V)mod N, the absolute value of V is 1, the absolute value of W is greater than K2 and less than N-K2, or the absolute values of V and W are integers greater than or equal to K3 and less than or equal to N-K3. The third sequence is any base sequence other than the first sequence and the second sequence in the X base sequences; and the terminal device transmits the reference signal sequence.
