Abstract
A subscriber station configured to communicate with one or more base stations or other transmission points (TPs) in a wireless communication network is configured to receive, from the network, information associated with one or more of the TPs that are candidates for coordinated multipoint (CoMP) transmission with the subscriber station, to measure a plurality of channel quality values for each of the one or more TPs, and to report the measured channel quality values to the network.
Claims20
A base station for measurement configuration in a wireless communication system, the base station comprising:
- a transceiver;
- and
- a controller configured to:
- transmit, to a user equipment (UE) via the transceiver, measurement configuration information including frequency information and channel state information reference signal (CSI-RS) information, the CSI-RS information including a physical cell identifier (ID), a CSI-RS index, and sequence generation information for a CSI-RS,
- transmit, to the UE via the transceiver, report configuration information including a threshold for an event, and
- receive, from the UE via the transceiver, a measurement report for the event that is generated based on a measured reference signal received power (RSRP) of the CSI-RS and the threshold according to the measurement configuration information and the report configuration information and the report configuration information.
A method for measurement configuration by a base station in a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), measurement configuration information including frequency information and channel state information reference signal (CSI-RS) information, the CSI-RS information including a physical cell identifier (ID), a CSI-RS index, and sequence generation information for a CSI-RS;
- transmitting, to the UE, report configuration information including a threshold for an event;
- and
- receiving, from the UE, a measurement report for the event that is generated based on a measured reference signal received power (RSRP) of the CSI-RS and the threshold according to the measurement configuration information and the report configuration information and the report configuration information.
