Abstract
A method and an apparatus for providing zone based prediction. The method includes determining, by a base station, a plurality of zones by dividing a coverage area of a cell, receiving, by the base station, channel state information (CSI) from a user equipment (UE), identifying, by the base station, a first zone from the plurality of zones where the UE encounters an obstructed area based on the CSI at a time domain, and allocating, by the base station, at least one resource to the UE to compensate for signal losses if the UE enters the obstructed area.
Claims16
A method for allocating a resource by a base station using a plurality of beams in a wireless communication system, the method comprising:
- determining a plurality of zones within a cell coverage of the base station, wherein the plurality of zones are zones in which an interference signal strength greater than a threshold is detected;
- receiving channel state information (CSI) from a user equipment (UE);
- identifying a first zone in which the UE has entered from the plurality of zones based on the CSI at a time domain, wherein the first zone is a zone in which a maximum interference signal strength is detected;
- and
- allocating a plurality of resources for the first zone to the UE,
- wherein when the UE is in a connected mode, setting a bit indicating an uplink resource for prediction information in a physical downlink control channel (PDCCH) or a dedicated common control channel, and
- wherein the uplink resource includes at least one of geographical position values, a moving direction, a doppler shift, and the CSI.
A base station for allocating a resource by the base station using a plurality of beams in a wireless communication, wherein the base station comprises:
- a transceiver configured to receive channel state information (CSI) from the UE;
- and
- a controller configured to:
- determine a plurality of zones within a cell coverage of the base station, wherein the plurality of zones are zones in which an interference signal strength greater than a threshold is detected,
- identify a first zone in which the UE has entered from the plurality of zones based on the CSI at a time domain, wherein the first zone is a zone in which a maximum interference signal strength is detected,
- allocate a plurality of resources for the first zone to the UE, and
- set a bit indicating an uplink resource for prediction information in a physical downlink control channel (PDCCH) or a dedicated common control channel when the UE is in a connected mode,
- wherein the uplink resource includes at least one of geographical position values, a moving direction, a doppler shift, and the CSI.
A method for receiving resource allocation information by a user equipment (UE) in a wireless communication system comprising a base station using a plurality of beams, the method comprising:
- transmitting channel state information (CSI) to the base station;
- and
- receiving, from the base station, the resource allocation information indicating a plurality of resources for a first zone to the UE when the UE enters the first zone among a plurality of zones within a cell coverage of the base station,
- wherein the plurality of zones are zones in which an interference signal strength greater than a threshold is detected, and the first zone is a zone in which a maximum interference signal strength is detected,
- wherein when the UE is in a connected mode, receiving a bit indicating an uplink resource for prediction information in a physical downlink control channel (PDCCH) or a dedicated common control channel, and
- wherein the uplink resource includes at least one of geographical position values, a moving direction, a doppler shift, and the CSI.
A user equipment (UE) for allocating a resource by a base station using a plurality of beams in a wireless communication system, the UE comprising:
- a transceiver configured to transmit channel state information (CSI) to the base station, and receive, from the base station, the resource allocation information indicating a plurality of resources for a first zone to the UE when the UE enters the first zone among a plurality of zones within a cell coverage of the base station,
- wherein the plurality of zones are zones in which an interference signal strength greater than a threshold is detected, and the first zone is a zone in which a maximum interference signal strength is detected,
- wherein when the UE is in a connected mode, the transceiver is further configured to receive a bit indicating an uplink resource for prediction information in a physical downlink control channel (PDCCH) or a dedicated common control channel, and
- wherein the uplink resource includes at least one of geographical position values, a moving direction, a doppler shift, and the CSI.
