CSI MEASUREMENT UNDER COVERAGE ENHANCEMENTS IN LTE

摘要

Methods and systems are disclosed for determining channel state information (CSI) when received uplink grants occupy a plurality of subframes and include a transmission time interval (TTI) bundle. Based at least in part on a configuration of the received TTI bundle, one or more subframes may be identified as CSI reference subframes to be used for CSI measurement. The CSI reference subframes may correspond to subframes or sub-bands used by the received uplink grant, or may be a predefined number of subframes before a CSI data transmission.

1. A method for wireless communication, comprising:
identifying, based at least in part on a configuration of a transmission time interval (TTI) bundle, one or more subframes as channel state information (CSI) reference subframes to be used for CSI measurement; performing CSI measurement of the CSI reference subframes; and transmitting CSI data based at least in part on the CSI measurement.
