Abstract:
A method for transmitting user data from a lower-layer split central unit (LLS-CU) to a radio unit (RU) in a network node of a wireless communication system for transmission by the RU over a wireless interface includes mapping reference symbols to be transmitted by the RU to resource elements to provide mapped data. The mapped data including the references symbols is compressed using a bitmap representation of the mapped data to obtain compressed data. The compressed data is transmitted from the LLS-CU to the RU.
