Abstract
Method and apparatus for HARQ procedures for DVC. The apparatus sorts one or more bits of a payload based on a corresponding priority. The apparatus divides the payload into one or more groups based on the corresponding priority, where each of the one or more groups is encoded separately. The apparatus transmits, to a second wireless device, a video frame over a span of one or more slots based at least on a prioritized transmission of the one or more groups.
Claims29
An apparatus for wireless communication at a first wireless device, comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the apparatus to:
- sort one or more bits of a payload based on a corresponding priority;
- divide the payload into one or more groups based on the corresponding priority, wherein each of the one or more groups is encoded separately;
- and
- transmit, to a second wireless device, a video frame over a span of one or more slots based at least on a prioritized transmission of the one or more groups.
An apparatus for wireless communication at a second wireless device, comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the apparatus to:
- receive, from a first wireless device, a video frame over a span of one or more slots based at least on a prioritized transmission of one or more groups of a divided payload;
- and
- transmit, to the first wireless device, an acknowledgement (ACK) or non-acknowledgment (NACK) of reception of the video frame, wherein transmission of the video frame is based on the prioritized transmission or a prioritized retransmission of the one or more groups having a higher priority over the one or more groups having a lower priority.
An apparatus for wireless communication at a first wireless device, comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the apparatus to:
- perform a prediction enhancement of a video compression output, wherein the prediction enhancement is based at least on an interleave operation or a code block order operation;
- and
- transmit, to a second wireless device, encoded systematic bits of a video frame comprising an imbalance enhancement of a prediction quality based on the prediction enhancement.
An apparatus for wireless communication at a second wireless device, comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to cause the apparatus to:
- receive, from a first wireless device, encoded systematic bits of a video frame comprising an imbalance enhancement of a prediction quality based on a prediction enhancement, wherein the prediction enhancement is based at least on an interleave operation or a code block order operation;
- and
- perform a complementary prediction enhancement procedure comprising at least one of a de-interleave operation or a code block de-order operation on decoded systematic bits of the video frame to predict content of one or more subsequent video frames based on a previously received video frame.
