Claim of US Patent No. 10,602,504

1. A method for wireless communications by a user equipment (UE), comprising:receiving signaling of a first uplink/downlink (UL/DL) subframe configuration for communicating with a base station (BS), wherein the first UL/DL subframe configuration is signaled via a system information block (SIB);
receiving a dynamically-signaled second UL/DL subframe configuration;
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, wherein detecting the collision is based on determining a downlink reference subframe for the CSI reporting associated with the second UL/DL subframe configuration;
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.
