Abstract

The invention provides a beam failure recovery processing method, a terminal and a network side device. The method comprises the following steps: the terminal sends a beam failure recovery request tothe network side device; and if the terminal determines that there is no available candidate beam, the terminal performs candidate beam measurement within a first preset time. That is, after the terminal measures beam failure, if there is no available candidate beam, the terminal does not report link failure at first, but waits for a period of time, and performs candidate beam measurement within the period of time so as to ensure the physical layer recovery beam of interaction between the terminal and the network side as much as possible, so that unnecessary recovery delay is shortened.

Description

technical field [0001] The present application relates to wireless communication technologies, and in particular to a beam failure recovery processing method, terminal and network side equipment. Background technique [0002] In the future 5G (5Generation, fifth generation) mobile communication system, in order to achieve the target of a downlink transmission rate of 20 megabits per second (Gbps) and an uplink transmission rate of 10 Gbps, high-frequency communication and large-scale antenna technology will be adopted. introduce. Specifically, high-frequency communication can provide wider system bandwidth and smaller antenna size, which is more conducive to the deployment of large-scale antennas in base stations and terminals. However, high-frequency communication has disadvantages such as large path loss, susceptibility to interference, and fragile links, and large-scale antenna technology can provide large antenna gain. Therefore, the combination of high-frequency commun...
