Abstract

The embodiment of the invention discloses an uplink transmission method on an unlicensed frequency band and terminal equipment. The problems that in the prior art, the transmission mode on an unauthorized frequency band is single, and the transmission efficiency is low are solved. The method is applied to terminal equipment, and the terminal equipment is frame-based equipment FBE (Fiber Bragg Element), and comprises the following steps of: monitoring the idle and busy states of an uplink transmission channel or detecting a channel occupation time sharing indication according to a time domain position relationship between uplink resources and a fixed frame period FFP (Fiber Bragg Period) of the FBE; and determining whether to use the uplink resources to perform uplink transmission or not according to the interception result or the detection result. According to the technical scheme, each uplink transmission does not need to be based on indication of the base station, and signaling overhead can be reduced; and the flexibility of interception or detection operation during FBE uplink transmission can be realized, so that the uplink transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an uplink transmission method and terminal equipment on an unlicensed frequency band. Background technique [0002] In future communication systems, unlicensed frequency bands can be used as a supplement to licensed frequency bands to help operators expand services. In order to be consistent with NR (New Radio, new air interface) deployment and maximize NR-based unlicensed access as much as possible, the unlicensed frequency band can work in the 5GHz, 37GHz and 60GHz frequency bands. The large bandwidth (80 or 100 MHz) of the unlicensed frequency band can reduce the implementation complexity of the base station and UE (User Equipment, user end). Since the unlicensed frequency band is shared by multiple technologies (RATs), such as WiFi, radar, LTE (Long Term Evolution, long-term evolution) LAA (LicenseAssisted Access, authorized spectrum assisted access), etc., in some coun...
