APPARATUSES, METHODS AND COMPUTER PROGRAM PRODUCTS RELATED TO IMPROVEMENTS IN DMRS TRANSMISSION

摘要

According to at least an aspect of the present invention, there is provided, under an network transceiver device aspect of e.g. an eNB, an apparatus, comprising a controller configured to cause a first set of reference signals to be transmitted at specific locations within a time and frequency resource grid, receive information indicative of a usability of a second set of reference signals within the resource grid, the second set comprising less reference signals as compared to the first set, analyse the received information, and responsive thereto generate control information, and cause to apply the second set of reference signals at specific locations within the time and frequency resource grid to be transmitted, and cause to transmit the generated control information in downlink so as to inform terminals being in communication with said apparatus of said second set of reference signals being applied. A corresponding apparatus in terms of a terminal device of e.g. a UE is also provided as well as respective corresponding methods and computer program products.
