Abstract
A wireless system comprises a controlling node and multiple antenna processing nodes coupled to the controlling node but separated from each other. The controlling node receives (720) first soft bit information from a first antenna processing node, the first soft bit information corresponding to reception of a wireless transmission. Responsive to determining that it cannot decode transmitted bits using the first soft bit information, the controlling node requests (730) and receives (740) second soft bit information from a second antenna processing node, the second soft bit information also corresponding to the first wireless transmission from the wireless device and having been buffered by the second antenna processing node. The controlling node decodes (750) bits from the first wireless transmission using both the first and second soft bit information. The controlling node may then signal the antenna processing nodes that they can discard buffered information for the wireless transmission.
