Title: METHOD FOR DETERMINING DMRS PORT MAPPING, AND BASE STATION AND TERMINAL
Abstract:
Provided are a method for determining DMRS port mapping, and a base station and terminal, the method on the base-station side being: a base station determining an index of a beam corresponding to a terminal; according to the correlation between the index of the beam corresponding to said terminal and the mapping number of the DMRS port, the base station determining the mapping number of the DMRS port of the terminal; according to the determined mapping number of the DMRS port of the terminal, the base station determining the port mapping of the DMRS of the terminal; according to the DMRS port mapping, the base station sending the DMRS to the terminal. In the method, a correlation between beam information and DMRS port mapping is established, such that there is a high likelihood that two terminals corresponding to different beams will be mapped to different DMRS ports.
