Abstract
Channel state information is generated by a communication device. The device can determine that at least one uplink resource element of a radio frame is to be left unoccupied and perform at least one interference measurement on at least one downlink resource element coinciding with the at least one unoccupied uplink resource element, A channel state information report can then be generated based on the measurement, A network node may cause the communication device to leave at feast one uplink resource element of a radio frame unoccupied.
Claims24
A method for providing channel state information by a communication device, comprising
- determining that at least one uplink resource element of a radio frame is to be left unoccupied,
- performing by the communication device at least one interference measurement on at least one downlink resource element coinciding with the at least one unoccupied uplink resource element, and
- generating a channel state information report based on the measurement.
A method for channel state information reporting, comprising
- causing a communication device to leave at least one uplink resource element of a radio frame unoccupied, and
- receiving a channel state information report based on at least one interference measurement by the communication device on at least one downlink resource element coinciding with the at least one unoccupied uplink resource element.
An apparatus for a communication device, the apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the communication device to
- leave at least one uplink resource element of a radio frame unoccupied,
- perform at least one interference measurement on at least one downlink resource element coinciding with the at least one unoccupied uplink resource element, and
- generate a channel state information report based on the measurement.
An apparatus for a network element, the apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause
- a communication device to leave at least one uplink resource element of a radio frame unoccupied, and
- handling of a channel state information report based on at least one interference measurement by the communication device on at least one downlink resource element coinciding with the at least one unoccupied uplink resource.
