Title: METHOD AND APPARATUS FOR REPORTING CHANNEL STATE INFORMATION
Abstract:
An indication can be received at a device from a network (1310). The indication can request the device to feedback channel state information corresponding to a first transmit time interval length operation and/or a second transmit time interval length operation. When the indication requests channel state information feedback for the first transmit time interval length operation: a first reference transmit time interval of a first transmit time interval length can be determined (1330) based on the transmit time interval in which the indication is received; and a channel measurement to compute the channel state information can be derived (1340) using reference signals associated with the first reference transmit time interval, and/or an interference measurement to compute the channel state information can be derived using measurements made on resource elements associated with the first reference transmit time interval. When the indication requests channel state information feedback for the second transmit time interval length operation: a second reference transmit time interval of a second transmit time interval length can be determined (1350) based on the transmit time interval in which the indication is received; and a channel measurement to compute the channel state information can be derived (1360) using reference signals associated with the second reference transmit time interval, and/or an interference measurement to compute the channel state information can be derived using measurements made on resource elements associated with the second reference transmit time interval.
