Abstract
A method and user equipment for channel state information (CSI) reporting are described. The method receives a channel quality indicator request. The method determines a channel quality indicator based on a CSI reference resource. The method transmits a CSI report that includes the channel quality indicator via a Physical Uplink Control CHannel (PUCCH) on an uplink subframe. The CSI reference resource belongs to a subframe subset for which the CSI report is sent. The CSI reference resource includes overhead of Demodulation Reference Signals according to a corresponding rank report.
Claims18
A method comprising:
- receiving a channel quality indicator request;
- determining a channel quality indicator based on a channel state information (CSI) reference resource;
- and
- transmitting a CSI report that includes the channel quality indicator via a Physical Uplink Control CHannel (PUCCH) on an uplink subframe, wherein the CSI reference resource belongs to a subframe subset for which the CSI report is sent, and wherein the CSI reference resource includes overhead of Demodulation Reference Signals according to a corresponding rank report.
A user equipment comprising:
- a transceiver configured to receive a channel quality indicator request;
- and
- a processor configured to determine a channel quality indicator based on a channel state information (CSI) reference resource,
- wherein the transceiver is configured to transmit a CSI report that includes the channel quality indicator via a Physical Uplink Control CHannel (PUCCH) on an uplink subframe, wherein the CSI reference resource belongs to a subframe subset for which the CSI report is sent, and wherein the CSI reference resource includes overhead of Demodulation Reference Signals according to a corresponding rank report.
