Problems solved by technology

[0005] For uplink-LBT, because there are fewer perception opportunities than WIFI systems, it is difficult for LBT based on FBE (Frame Based Equipment) to compete with WIFI for channel access

Abstract

The invention discloses a method of realizing uplink access on a base station end. The method comprises steps that a plurality of user terminals to be connected with the base station end are divided into a plurality of access groups; corresponding frequency spectrum resources are allocated to every access group, and in each access group, the same frequency spectrum resource is allocated to every user terminal; in each access group, an initial clear channel assessment iCCA boundary and a transmission boundary are allocated to every user terminal, and the iCCA boundary of every user terminal is disposed on an ending boundary in a corresponding time slot; the information of the corresponding frequency spectrum resource, the information of the corresponding iCCA boundary, and the information of the corresponding transmission boundary are transmitted to every user terminal. The iCCA boundaries and the transmission boundaries are dynamically provided for the user terminals explicitly or implicitly, and can be configured by high level signaling in a semi-static way. The invention also discloses a method and a device of realizing the uplink access on the user terminals.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of wireless communication, and in particular, relate to a method and device for realizing uplink access at a base station, and a method and device for realizing uplink access at a user end. Background technique [0002] In the 78th meeting of RAN1, it was agreed to use "Listen-Before-Talk" (LBT: Listen-Before-Talk) as a necessary identification function to meet the control requirements of unlicensed frequency bands in some regions, for example, Europe , for the LAA system. According to the requirements of the LBT, the user should perform a clear channel assessment (CCA: Clear Channel Assessment) before performing uplink transmission on an unlicensed carrier. [0003] Compared with the operation of the existing implementation, the main difference of the uplink transmission implemented on the unlicensed carrier is that before transmitting the PUSCH in the LAA system, LBT needs to be implemented a...
