Problems solved by technology

[0003] It can be seen that the random access process based on the existing contention includes many steps, and the delay is relatively large, so it is not suitable for scenarios with high delay requirements.

Embodiment Construction

[0068] Please refer to figure 1 , which is a schematic diagram of a communication system provided in an embodiment of the present application. Such as figure 1 As shown, the terminal device 130 is connected to a wireless network, so as to obtain services of an external network (such as the Internet) through the wireless network, or communicate with other terminal devices through the wireless network. The wireless network includes a RAN110 and a core network (CN) 120, wherein the RAN110 is used to connect the terminal equipment 130 to the wireless network, and the CN120 is used to manage the terminal equipment and provide a gateway for communication with the external network.

[0069] Terminal equipment, also called user equipment (UE), mobile station (mobile station, MS), mobile terminal (mobile terminal, MT), etc., is a device that provides voice / data connectivity to users, such as , a handheld device with a wireless connection function, or a vehicle-mounted device, etc. A...

Abstract

An embodiment of the invention discloses a communication method and a communication device, which are used for reducing the time delay of random access of terminal equipment. The communication methodprovided by the embodiment of the invention comprises the following steps that: the terminal equipment transmits a first message to network equipment, wherein the first message comprises a random access signal and information used for competition resolution, and the random access signal and the information used for competition resolution are transmitted through pre-allocated resources; and the terminal equipment receives a response message of the first message from the network equipment, wherein the response message is used for indicating a random access state of the terminal equipment.

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] A random access (random access, RA) process is used to establish uplink synchronization between a terminal device and a network device, and includes a contention-based random access process and a non-contention random access process. At present, the contention-based random access process is completed in four steps: the first step is that the terminal device sends a random access request to the network device. The random access request can also be called message 1 (Msg1), which contains the random access preamble The second step is that the network device sends a random access response (random access response, RAR) message to the terminal device, and the RAR message can also be called message 2 (Msg2); the third step is that the terminal device, after receiving the RAR, The message is transmitted...
