Apparatus, and associated method, for assigning data to transmit antennas of a multiple transmit antenna transmitter
First Claim
1. A radio communication system having a multiple-antenna transmitter that selectably transmits data at least from a first transmit antenna transducer and at least a second transmit antenna transducer for communication to a receiver, an apparatus comprising:
- an encoder which encodes the data, the data encoded comprises a systematic part and a non-systematic part;
a determiner at least adapted to receive indications of channel conditions of each channel upon which data is transmitted by each of the first and at least second transmit antenna transducers, respectively, said determiner for determining at least relative channel qualities of each of the channels; and
a data assignor coupled to said determiner to receive indications of determinations made thereat, said assignor for assigning the systematic part of the data encoded by the encoder to at least one of the first and at least second transmit antenna transducers that exhibits better channel qualities,wherein the indications of the channel conditions which said determiner is adapted to receive comprise indications of aggregated energy levels of the data detected at the receiver.

Abstract
Apparatus, and an associated method, for facilitating communication of encoded data, formed of a systematic part and a non-systematic part, in a radio communication system. Systematic parts of the encoded data are assigned by an assignor to transmit antennas that are associated with communication channels exhibiting better, or best, communication quality levels. Determinations are made of communication conditions to rank the transmit antennas, thereby permit appropriate assignments of the encoded data to transmit antennas. Feedback is provided by the receiver that receives the transmitted data. The feedback information includes, or is formed responsive to, detections and other measurements at the receivers.
