Title: UPLINK CHANNEL ACCESS METHOD AND RELATED DEVICE
Abstract:
Embodiments of the present invention provide an uplink channel access method and a user equipment (UE), for used in resolving the problem of uplink channel access in a licensed-assisted access (LAA) system. The method is applied to an LAA system, and comprises: a UE receives an uplink data scheduling mode sent by a base station, the uplink data scheduling mode comprising cross-carrier scheduling and self-scheduling; the UE accesses an uplink channel by a first mode when the uplink data scheduling mode is a cross-carrier scheduling mode, wherein the first mode comprises a first parameter which is an uplink channel access parameter configured for the UE by the base station; the UE accesses the uplink channel by a second mode when the uplink data scheduling mode is a self-scheduling mode, wherein the second mode is an LBT mode having no random backoff mechanism.
