Abstract

The embodiment of the invention discloses a random access method and device, and relates to the technical field of communication, so that a terminal device which is configured with a PUL and at leastone SUL and is in a connection state determines an uplink carrier initiating random access to complete random access. The random method is applied to a chip in terminal equipment which is in a connected state and is configured with at least two uplink carriers or the terminal equipment. The method comprises the following steps: receiving first information sent by access network equipment, whereinthe first information is used for determining at least one uplink carrier with random access resources in at least two uplink carriers; determining an uplink carrier wave initiating random access in the at least one uplink carrier wave having the random access resource; And initiating random access on the uplink carrier wave initiating the random access.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a random access method and apparatus. Background technique [0002] In order to meet the large-capacity and high-speed transmission requirements of mobile communication systems, the 5th Generation Mobile Communication Technology (5G) system introduces a high-frequency frequency band greater than 6 gigahertz (GHz) for communication. Generally, the transmission power of the terminal equipment is relatively low. In this way, when the terminal equipment is located in the edge area of ​​the cell and uses the high-frequency uplink carrier to send signals to the base station, the high-frequency signal has a large transmission loss during the transmission process, and the penetrating ability is high. Therefore, the base station may not be able to receive the signal sent by the terminal device, but the terminal device can receive the signal sent b...
