Abstract
An MAC control element (CE) uplink configuration method and device, and communications system, the method includes: when an MAC CE is activated, determining, by user equipment (UE), whether an uplink grant of a serving cell in an authorization frequency band exists; and when the uplink grant of the serving cell in the authorization frequency band exists and can accommodate the MAC CE, allocating, by the UE and for the MAC CE, the uplink grant of the serving cell in the authorization frequency band. An embodiment of the present disclosure improves reliability for transmitting the MAC CE, in an LAA system, and reduces unnecessary latency or failure.
Claims19
A medium access control (MAC) control element uplink configuration method, comprising:
- determining, by user equipment (UE), whether there exists an uplink grant of a serving cell in a licensed band when an MAC control element is triggered;
- and
- allocating, by the UE, the uplink grant of the serving cell in the licensed band for the MAC control element in a case where there exists the uplink grant of the serving cell in the licensed band and the uplink grant of the serving cell in the licensed band is capable of accommodating the MAC control element.
An MAC control element uplink configuration device, comprising:
- a determining unit configured to determine whether there exists an uplink grant of a serving cell in a licensed band when an MAC control element is triggered;
- and
- a configuring unit configured to allocate the uplink grant of the serving cell in the licensed band for the MAC control element in a case where there exists uplink grant of the serving cell in the licensed band and the uplink grant of the serving cell in the licensed band is capable of accommodating the MAC control element.
A communications system, comprising:
- UE configured to determine whether there exists an uplink grant of a serving cell in a licensed band when an MAC control element is triggered, and allocate the uplink grant of the serving cell in the licensed band for the MAC control element in a case where there exists the uplink grant of the serving cell in the licensed band and the uplink grant of the serving cell in the licensed band is capable of accommodating the MAC control element.
