Abstract
Certain aspects of the present disclosure provide techniques that may help ensure downlink packet bursts are delivered to a UE within a deadline. Certain aspects provide a method wireless communications by a user equipment (UE), comprising determining a deadline for arrival of bursts of packets at the UE, sending an indication of the deadline to a network entity, and monitoring for bursts of packets from the network entity in accordance with the deadline.
Claims22
A method for wireless communication by a user equipment (UE), comprising:
- determining a first deadline for arrival of bursts of packets at the UE based on an indication from an application client operating on the UE;
- sending an indication of the first deadline to a network entity;
- and
- monitoring for bursts of packets from the network entity in accordance with a second deadline determined based on the first deadline and a periodicity, wherein the periodicity is subject to jitter.
A method for wireless communication by a network entity, comprising:
- receiving, from a user equipment (UE), an indication of a first deadline for arrival of at least one of bursts of packets at the UE;
- receiving an indication of a periodicity of the bursts of packets;
- determining a second deadline for a given packet of the bursts of packets based, at least in part, on the periodicity and the first deadline indicated by the UE;
- and
- sending the bursts of packets to the UE in accordance with the second deadline.
A method for wireless communication by a network entity, comprising:
- receiving an indication of a nominal packet delay budget (PDB);
- determining a deadline, for a given packet of bursts of packets, for arrival of the packet at a user equipment (UE) based on a nominal arrival time for the packet, the nominal PDB, and a periodicity of the bursts, wherein the periodicity is subject to jitter, the network entity inferring the periodicity based on observed times between bursts of packets;
- and
- sending the bursts of packets to the UE in accordance with the deadline.
An apparatus for wireless communications by a user equipment (UE), comprising:
- a memory and at least one processor coupled to the memory, the memory and the at least one processor being configured to:
- determine a first deadline for arrival of bursts of packets at the UE based on an indication from an application client operating on the UE;
- send an indication of the first deadline to a network entity;
- and
- monitor for bursts of packets from the network entity in accordance with a second deadline determined based on the first deadline and a periodicity, wherein the periodicity is subject to jitter.
An apparatus for wireless communications by a network entity, comprising:
- a memory and at least one processor coupled to the memory, the memory and the at least one processor being configured to:
- receive, from a user equipment (UE), an indication of a first deadline for arrival of at least one of bursts of packets at the UE;
- receive an indication of a periodicity of the bursts of packets;
- determine a second deadline for a given packet of the bursts of packets based, at least in part, on the periodicity and the first deadline indicated by the UE;
- and
- send the bursts of packets to the UE in accordance with the second deadline.
An apparatus for wireless communications by a network entity, comprising:
- a memory and at least one processor coupled to the memory, the memory and the at least one processor being configured to:
- receive an indication of a nominal packet delay budget (PDB);
- determine a deadline, for a given packet of bursts of packets, for arrival of the packet at a user equipment (UE) based on a nominal arrival time for the packet, the nominal PDB, and a periodicity of the bursts of packets, wherein the periodicity is subject to jitter, the network entity inferring the periodicity based on observed times between bursts of packets;
- and
- send the bursts of packets to the UE in accordance with the deadline.
