Title:
METHOD AND APPARATUS OF QUASI-COLOCATION ASSUMPTION DETERMINATION FOR PHYSICAL DOWNLINK SHARED CHANNEL
Document Type and Number:
WIPO Patent Application WO/2022/191617
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Methods and apparatuses in a wireless communication system is provided. A method for operating a user equipment (UE) includes receiving a set of higher layer parameters and downlink control information (DCI); determining, based on the set of higher layer parameters, whether a field is present; and determining, from the DCI, a first set of antenna ports for de-modulation reference signal (DM-RS) associated with a first physical downlink shared channel (PDSCH). The method further includes, in response to a determination that the field is present, determine that a second set of antenna ports for DM-RS are not associated with a second PDSCH for another UE and receiving the first PDSCH over a downlink channel. The second set of antenna ports for DM-RS: are orthogonal to, have a same resource element mapping as; and have a different frequency domain orthogonal cover code (FD-OCC) from the first set of antenna ports for DM-RS.
