Abstract
A first antenna processing node receives (710) one or more wireless transmissions from a wireless device and obtains first symbol values from the one or more wireless transmissions. The first antenna processing node receives (720) second symbol values from a second antenna processing node, the second symbol values corresponding to the one or more wireless transmissions as received at the second antenna processing node, and calculates (730) a first weight parameter based on at least a subset of the first symbol values and a corresponding subset of the second symbol values. The first antenna processing node calculates (740) third symbol values by computing a weighted sum of first symbol values and corresponding ones of the second symbol values, using the first weight parameter, and sends (750) the third symbol values to a third antenna processing node or to a controlling node. This combining of symbol values may approximate maximum ratio combining, MRC.
