Abstract

The present application provides a communication method and device. The method includes: designing the preamble as a weighted sum of multiple quasi-orthogonal sequences, or designing the preamble as a weighted sum of multiple orthogonal sequences, thereby expanding the capacity of the preamble in limited physical resources, Meet the needs of a large number of terminals to access the network.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] In a wireless communication network, when trying to access a wireless network, a terminal can send a preamble to a network device to initiate a random access process. However, limited by the physical resources capable of carrying the preamble, the capacity of the preamble is insufficient, which cannot meet the requirements of a large number of terminals for accessing the network. Therefore, how to expand the capacity of the preamble in limited physical resources has become an urgent problem to be solved. Contents of the invention [0003] Embodiments of the present application provide a communication method and device. [0004] In the first aspect, the embodiment of the present application provides a communication method, which can be executed by a terminal or by a component of the terminal (...
