Abstract
Techniques are described for wireless communication. One method of wireless communication includes buffering a first set of coded bits including a first control message having a plurality of fields, buffering a second set of coded bits including a second control message having the plurality of fields, soft combining at least a first subset of the first set of coded bits and a second subset of the second set of coded bits in a combined set of coded bits, and decoding the first control message or the second control message based at least in part on the combined set of coded bits.
Claims26
A method of wireless communication at a receiving device, comprising:
- buffering a first set of coded bits including a first control message having a plurality of fields;
- buffering a second set of coded bits including a second control message having the plurality of fields;
- generating sequential ranks of the first set of coded bits and the second set of coded bits, wherein each rank of coded bits is generated based on a different subset of information bits in the first control message or the second control message, and wherein each lower rank of coded bits is generated based on a subset of the information bits used to generate a next higher rank of coded bits;
- soft combining at least a first subset of the first set of coded bits and a second subset of the second set of coded bits in a combined set of coded bits, wherein the soft combining is performed for the sequential ranks beginning with a lowest rank;
- and
- decoding the first control message or the second control message based at least in part on the combined set of coded bits.
