A method for wireless communications by a user equipment, UE, in a Long Term Evolution, LTE, communication system comprising: receiving signaling of a first time division duplex, TDD, uplink/downlink, UL/DL, subframe configuration for communicating with a base station, BS; receiving signaling of at least one channel state information, CSI, reporting configuration indicating at least two subframe sets, where each subframe set is associated with an interference measurement resource, IMR, configuration; detecting a collision of CSI reporting for the at least two subframe sets in an uplink subframe; prioritizing one subframe set from the at least two subframe sets for CSI reporting in the uplink subframe; and reporting CSI in the uplink subframe based on the prioritization; the method characterised in comprising: receiving a dynamically signaled indication indicating a second TDD UL/DL subframe configuration; determining that the second TDD UL/DL subframe configuration reconfigures a downlink reference subframe for CSI reporting as an uplink subframe; altering CSI reporting in response to the determining that the second TDD UL/DL subframe configuration reconfigures the downlink reference subframe for CSI reporting as an uplink subframe, where the altering comprises at least one of sending a measurement report with a value that is at least one of: outdated or out of range; or omitting a CSI report. receiving signaling of a first time division duplex, TDD, uplink/downlink, UL/DL, subframe configuration for communicating with a base station, BS; receiving signaling of at least one channel state information, CSI, reporting configuration indicating at least two subframe sets, where each subframe set is associated with an interference measurement resource, IMR, configuration; detecting a collision of CSI reporting for the at least two subframe sets in an uplink subframe; prioritizing one subframe set from the at least two subframe sets for CSI reporting in the uplink subframe; and reporting CSI in the uplink subframe based on the prioritization; the method characterised in comprising: receiving a dynamically signaled indication indicating a second TDD UL/DL subframe configuration; determining that the second TDD UL/DL subframe configuration reconfigures a downlink reference subframe for CSI reporting as an uplink subframe; altering CSI reporting in response to the determining that the second TDD UL/DL subframe configuration reconfigures the downlink reference subframe for CSI reporting as an uplink subframe, where the altering comprises at least one of sending a measurement report with a value that is at least one of: outdated or out of range; or omitting a CSI report. receiving a dynamically signaled indication indicating a second TDD UL/DL subframe configuration; determining that the second TDD UL/DL subframe configuration reconfigures a downlink reference subframe for CSI reporting as an uplink subframe; altering CSI reporting in response to the determining that the second TDD UL/DL subframe configuration reconfigures the downlink reference subframe for CSI reporting as an uplink subframe, where the altering comprises at least one of sending a measurement report with a value that is at least one of: outdated or out of range; or omitting a CSI report.
