Methods and apparatus for adjusting wireless communication structure

A method of wireless communication by a user equipment (UE), comprising:

• receiving radio resource control signaling indicating a timer associated with an adjustment of symbols within a self-contained wireless communication structure;
• determining that the UE is scheduled for reception of a low-latency packet in symbols of a first slot of the self-contained wireless communication structure, the first slot comprising a plurality of downlink and uplink symbols;
• receiving the low-latency packet in a scheduled portion of the first slot, wherein at least one symbol of the low-latency packet comprises an indicator of an adjustment for a plurality of downlink symbols of the first slot based at least in part on the scheduling of the low-latency packet, wherein the adjustment comprises changing a plurality of downlink symbols of the first slot to at least one symbol comprising a switching gap and at least one uplink symbol for transmitting ACK/NACK information associated with the low-latency packet, wherein the plurality of downlink symbols is adjusted based at least in part on the plurality of downlink symbols being included within an active duration of the timer, wherein the plurality of downlink symbols is separate from the scheduled portion of the first slot for receiving the low-latency packet;
• and
• transmitting an acknowledgement message comprising the ACK/NACK information associated with the low-latency packet on the at least one uplink symbol of the first slot that is subsequent to the switching gap, wherein the UE is configured to apply the adjustment for a quantity of slots, including the first slot, within the active duration of the timer.

An apparatus for wireless communication, comprising:

• a processor;
• and
• memory coupled with the processor, wherein the processor is configured to:
• transmit, to a user equipment (UE), radio resource control signaling indicating a timer associated with an adjustment of symbols within a self-contained wireless communication structure;
• schedule a low-latency packet for transmission to the UE in symbols of a first slot of the self-contained wireless communication structure, the first slot comprising a plurality of downlink and uplink symbols;
• adjust, based on the scheduling of the low-latency packet, a plurality of downlink symbols of the first slot to at least one symbol comprising a switching gap and at least one uplink symbol for transmitting ACK/NACK information associated with the low-latency packet, wherein adjusting the plurality of downlink symbols is based at least in part on the plurality of downlink symbols being included within an active duration of the timer, and wherein the plurality of downlink symbols is separate from a scheduled portion of the first slot for transmitting the low-latency packet;
• transmit the low-latency packet to the UE, wherein at least one symbol of the low-latency packet comprises an indicator of the adjusting, wherein the indicator of the adjusting applies to a quantity of slots, including the first slot, within the active duration of the timer;
• and
• receive, from the UE, an acknowledgement message comprising the ACK/NACK information associated with the low-latency packet on the at least one uplink symbol of the first slot that is subsequent to the switching gap.

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

• a processor;
• and
• a memory coupled with the processor, wherein the processor is configured to:
• receive radio resource control signaling indicating a timer associated with an adjustment of symbols within a self-contained wireless communication structure;
• determine that the UE is scheduled for reception of a low-latency packet in symbols of a first slot of the self-contained wireless communication structure, the first slot comprising a plurality of downlink and uplink symbols;
• receive the low-latency packet in a scheduled portion of the first slot, wherein at least one symbol of the low-latency packet comprises an indicator of an adjustment for a plurality of downlink symbols of the first slot based at least in part on the scheduling of the low-latency packet, wherein the adjustment comprises changing a plurality of downlink symbols of the first slot to at least one symbol comprising a switching gap and at least one uplink symbol for transmitting ACK/NACK information associated with the low-latency packet, wherein the plurality of downlink symbols is adjusted based at least in part on the plurality of downlink symbols being included within an active duration of the timer, wherein the plurality of downlink symbols is separate from the scheduled portion of the first slot;
• and
• transmit an acknowledgement message comprising the ACK/NACK information associated with the low-latency packet on the at least one uplink symbol of the first slot that is subsequent to the switching gap, wherein the UE is configured to apply the adjustment for a quantity of slots, including the first slot, within the active duration of the timer.
