Claim 0:
1. A method, performed by a first Antenna Processing Unit (APU) for sequential receive combining in a radio stripe system, wherein the radio stripe system comprises at least two APUs and a Central Processing Unit (CPU) the at least two APUs being connected in series to the CPU, wherein the radio stripe system serves at least two User Equipment (UEs) the method comprising:
obtaining channel estimates for channels to said served UEs;
determining a receive combining filter based on the obtained channel estimates, wherein the receive combining filter is going to be applied to received data signals;
determining effective channels from said served UEs based on the obtained channel estimates and the determined receive combining filter, wherein the effective channels represent the effective channel created after the receive combining filter being applied to each channel for said served UEs; and
transmitting the effective channels from said served UEs to at least one subsequent second APU.
