Traffic-aware grant signaling and processing

A method of wireless communication at a network device, comprising:

• identifying that a plurality of packets are scheduled for a downlink transmission to a user equipment (UE) via a packet-group transmission mode;
• selecting, from a packet buffer, one or more packet-groups for inclusion in a transmission payload for the downlink transmission in accordance with the packet-group transmission mode, wherein the packet-group transmission mode specifies that individual packets included in a packet-group include different sets of data indicative of different portions of a video frame, and wherein a time of arrival of at least one packet of the selected one or more packet-groups at the packet buffer occurs after a time of arrival of one or more unselected packets in the packet buffer;
• and
• transmitting, to the UE, the downlink transmission including the transmission payload in accordance with the packet-group transmission mode.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor to cause the apparatus to:
• receive, from a network device, an uplink grant for an uplink transmission from the UE to the network device;
• select, based at least in part on the uplink grant, a packet-group transmission mode for the uplink transmission, wherein the packet-group transmission mode specifies that individual packets included in a packet-group include different sets of data indicative of different portions of a video frame;
• select, from a packet buffer that includes a plurality of packets, one or more packet-groups for inclusion in a transmission payload for the uplink transmission in accordance with the uplink grant and based at least in part on the packet-group transmission mode, wherein a time of arrival of at least one packet of the selected one or more packet-groups at the packet buffer occurs after a time of arrival of one or more unselected packets in the packet buffer;
• and
• transmit, to the network device, the uplink transmission including the transmission payload in accordance with the packet-group transmission mode and the uplink grant.

An apparatus for wireless communication at a network device, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor to cause the apparatus to:
• transmit, to a user equipment (UE), an uplink grant, including an indication of a file delay budget or a file delay error rate, for an uplink transmission from the UE to the network device, wherein the uplink grant specifies a packet-group transmission mode for the uplink transmission, wherein individual packets included in a packet-group include different sets of data indicative of different portions of a video frame;
• and
• receive the uplink transmission from the UE, the uplink transmission including a transmission payload including one or more packet-groups in accordance with the uplink grant and the packet-group transmission mode.
