Title:
SYSTEM AND METHOD FOR PHASE TRACKING REFERENCE SIGNAL DYNAMIC PRESENCE IN ULTRA-RELIABLE AND LOW-LATENCY AND PORT INDICATION
Document Type and Number:
WIPO Patent Application WO/2020/146543
Kind Code:
A3
Abstract:
A user equipment wireless communication device in a wireless communication environment receives a signal from the network that includes a radio network temporary ID. From the radio network temporary ID, the user equipment is capable of determining whether a phase tracking reference signal is present based on the radio network temporary ID. If any of these are identified by the radio network temporary ID, then the user equipment determines that a phase tracking reference signal is present. After the user equipment has determined that the phase tracking reference signal is present, the user equipment can then determine which phase tracking reference signal antenna ports are to be used based on the values of the transmitted precoding matrix indicator value and the transmit rank indicator.
