Patent ID: 11552692

Abstract:
A method of operating an LLS-CU includes providing downlink signals to be transmitted to a UE over a wireless radio interface, allocating the downlink signals to resource elements, REs, of a physical downlink channel, generating a data-associated control information, DACI, message including a section description associated with the downlink signals, the DACI message including a resource element mask that defines the location of one or more REs within a PRB of a downlink signal on the physical downlink channel, and an indication of beamforming weights to be applied by a radio unit, RU, when transmitting the downlink signals to the UE, wherein the beamforming weights are associated with resource elements according to the resource element mask, transmitting the DACI message to the RU, and transmitting the downlink signals to the RU for transmission to the UE.
