Methods for conveying additional information via beam permutations
Abstract:
Aspects are provided which allow a transmitting device to provide reference signals to a receiving device for beam management according to an arbitrarily determined sequence of transmission beams at any time, and to implicitly convey information regarding the determined sequence of transmission beams to the receiving device. The transmitting device provides a message to the receiving device indicating a beam sequence conveyance mode. The transmitting device subsequently determines a sequence of different transmission beams, and associates a reference signal with each one of the transmission beams for transmission to the receiving device according to the sequence. The receiving device obtains the plurality of reference signals from the transmitting device, where each of the reference signals is associated with a different transmission beam. The receiving device identifies a reception beam for each of the transmission beams, and determines a sequence of the transmission beams in response to the identification.
