Title: SYSTEM AND METHOD FOR IMR ASSOCIATED WITH DATA TRANSMISSION
Abstract:
Systems and methods of compensating for interference in a 5G system are generally described. An Interference Measurement Resource (IMR) is present in multiple resource elements of a subframe or a combination of a ZP and NZP Tracking Reference Signal (PT-RS) are used. An IMR covariance matrix is applied to compensate for the interference. The number of IMR subcarriers and symbols between adjacent IMRs is dependent on the numerologies and synchronization within the UE network. When the IMR is in multiple subcarriers in the first symbol of the second slot, and the matrix is determined using the IMR rather than a DMRS. The DCI comprises a flag that denotes whether IMR is enabled for a current PDCH, and indicates the manner to use the IMR. The subcarrier index for the NZP PT-RS overlaps the subcarrier index for the ZP PT-RS of another UE or gNB.
