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 for wireless communication at a receiving device, comprising:
- buffering a first control message comprising a first set of coded bits, wherein the first control message is included in a first search space;
- buffering a second control message comprising a second set of coded bits, wherein the second control message is included in a second search space that is associated with a deterministic function relative to the first search space;
- performing a first blind decoding of a first resource allocation included in the first search space;
- performing, based at least in part on the deterministic function, a second blind decoding of a second resource allocation included in the second search space;
- soft combining the first set of coded bits and the second set of coded bits in a combined set of coded bits based at least in part on the first blind decoding and the second blind decoding;
- and
- decoding at least one of the first control message or the second control message based at least in part on the combined set of coded bits.
An apparatus for wireless communication at a receiving device, comprising:
- a processor,
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- buffer a first control message comprising a first set of coded bits, wherein the first control message is included in a first search space;
- buffer a second control message comprising a second set of coded bits, wherein the second control message is included in a second search space that is associated with a deterministic function relative to the first search space;
- perform a first blind decoding of a first resource allocation included in the first search space;
- perform, based at least in part on the deterministic function, a second blind decoding of a second resource allocation included in the second search space;
- soft combine the first set of coded bits and the second set of coded bits in a combined set of coded bits based at least in part on the first blind decoding and the second blind decoding;
- and
- decode at least one of the first control message or the second control message based at least in part on the combined set of coded bits.
A non-transitory computer-readable medium storing code for wireless communication at a receiving device, the code comprising instructions executable by a processor to:
- buffer a first control message comprising a first set of coded bits, wherein the first control message is included in a first search space;
- buffer a second control message comprising a second set of coded bits, wherein the second control message is included in a second search space that is associated with a deterministic function relative to the first search space;
- perform a first blind decoding of a first resource allocation included in the first search space;
- perform, based at least in part on the deterministic function, a second blind decoding of a second resource allocation included in the second search space;
- soft combine the first set of coded bits and the second set of coded bits in a combined set of coded bits based at least in part on the first blind decoding and the second blind decoding;
- and
- decode at least one of the first control message or the second control message based at least in part on the combined set of coded bits.
An apparatus for wireless communication at a receiving device, comprising:
- means for buffering a first control message comprising a first set of coded bits, wherein the first control message is included in a first search space;
- means for buffering a second control message comprising a second set of coded bits, wherein the second control message is included in a second search space that is associated with a deterministic function relative to the first search space;
- means for performing a first blind decoding of a first resource allocation included in the first search space;
- means for performing, based at least in part on the deterministic function, a second blind decoding of a second resource allocation included in the second search space;
- means for soft combining the first set of coded bits and the second set of coded bits in a combined set of coded bits based at least in part on the first blind decoding and the second blind decoding;
- and
- means for decoding at least one of the first control message or the second control message based at least in part on the combined set of coded bits.
