  • Apparatuses and methods for sequential transmit precoding
    Patent number: 12028131
    Abstract: The present disclosure relates to radio network communication. In one of its aspects, the present disclosure relates to a method, performed by a first APU, for sequential transmit precoding in a radio stripe system. The system comprises at least two APUs connected 5 in series from a CPU and serves at least two UEs. According to the method, channel estimates for channels to the served UEs are obtained and based on these, a precoding filter is determined. The precoding filter is going to be applied to signals that are to be transmitted from the first APU to the UEs. Thereafter, based on the determined precoding filter and the obtained channel estimates, effective precoded channels for the 0 signals to the UEs are determined. These represent the effective channel created after the precoding filter being applied to each channel for the UEs. The effective precoded channels are transmitted to at least one subsequent second APU.
