Title:
PILOT-DATA OVERLAP DESIGN FOR UPLINK TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2018/103382
Kind Code:
A1
Abstract:
Systems and methods are provided in which uplink transmission of pilot uses time-frequency resources that overlap with time-resources for the uplink transmission of data, by the same UE or different UEs. This can result in a decrease in pilot overhead, or if longer pilot sequences are used, can result in a decrease in collision probability. In a group-based approach, UEs are organized into groups, and each group is allocated the same resources for pilot and data.
