Abstract
A method for control-plane and user-plane transmissions in a customized C-RAN is disclosed. The method includes providing control-plane (CP) signaling using a first beam in a radio resource, and providing user-plane (UP) content using a second beam in the radio resource based on the CP signaling, wherein the first beam provides wider access coverage than the second beam. The radio resource is a licensed band or an unlicensed band. The first beam and the second beam are millimeter-wave beams. The first beam has an omni-directional beam pattern. The second beam has a directional beam pattern.
Claims19
A method for a user equipment (UE), the method comprising:
- receiving control-plane (CP) signaling using a first beam in a radio resource, the radio resource comprising time slots and a radio spectrum having an unlicensed band;
- receiving user-plane (UP) content using a second beam in the radio resource based on the CP signaling;
- wherein a first Listen-Before-Talk (LBT) procedure is performed by a transmitter before the UE receives the CP signaling using the first beam in the radio resource;
- wherein a second LBT procedure is performed by the transmitter before the UE receives the UP signaling using the second beam in the radio resource;
- wherein the second beam has a directional beam pattern;
- wherein the first beam uses a first unlicensed sub-band of the radio spectrum, and the second beam uses a second unlicensed sub-band of the radio spectrum.
A user equipment (UE) comprising:
- a receiver circuit configured to:
- receive control-plane (CP) signaling through a first beam in a radio resource, the radio resource comprising time slots and a radio spectrum having an unlicensed band;
- receive user-plane (UP) content using a second beam in the radio resource based on the CP signaling;
- wherein a first Listen-Before-Talk (LBT) procedure is performed by a transmitter before the UE receives the CP signaling using the first beam in the radio resource;
- wherein a second LBT procedure is performed by the transmitter before the UE receives the UP signaling using the second beam in the radio resource;
- wherein the second beam has a directional beam pattern;
- wherein the first beam uses a first unlicensed sub-band of the radio spectrum, and the second beam uses a second unlicensed sub-band of the radio spectrum.
