Abstract

Embodiments of the present invention provide a random access method and a user equipment. The method comprises: determining an available signature sequence set; selecting a first signature sequence from the available signature sequence set, and outputting the first signature sequence to a physical logic module; and the physical logic module executing signature sequence selection based on the first signature sequence, generating a preamble sequence according to a result of the signature sequence selection, and sending the preamble sequence to a base station. In the embodiments of the present invention, a determined first signature sequence is input into the physical logic module, so that in an entire random access process, the physical logic module always uses a same signature sequence.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication, and more specifically, to a random access method and user equipment. Background technique [0002] With the continuous development of communication technology, the new mobile communication system is favored due to its powerful multimedia communication capabilities, high-speed data transmission rate and efficient spectrum utilization, and has become the development goal of future mobile communication. [0003] Take Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) system as an example. WCDMA channels can be divided into two categories: dedicated channels and public channels. Wherein, the dedicated channel includes: a traffic channel, an independent dedicated control channel, and an associated dedicated control channel. Common channels include: broadcast control channel, forward access channel, paging channel, and random access chann...
