Patent ID: 11956107
Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A client device for a wireless communication system, comprising:
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the client device to:
determine at least one time-frequency resource allocated for a random access preamble;
determine a modulation sequence for the random access preamble, wherein the modulation sequence is based on a first sequence and a second sequence, the first sequence being a sequence from a set of near-orthogonal sequences and the second sequence being a sequence from a set of constant envelope sequences, wherein at least one of the first sequence or the second sequence is a Discrete Fourier Transform (DFT) sequence, a permutation of a DFT sequence, or a cyclic shift of a DFT sequence; and
transmit a signal comprising a random access preamble to a network access node, wherein the random access preamble comprises the modulation sequence mapped onto the determined at least one time-frequency resources.
