Apple patents flexible data retry rules for 5G connections
Apple describes a method for mobile devices to manage how they re-send data if a transmission fails. The device checks available time slots for sending data and chooses which retry process to use for each slot, mixing settings provided by the network with its own choices.
In the filing’s own words
Techniques for flexible hybrid automatic repeat request selection by a user equipment are provided. An example method includes a user equipment (UE) detecting a set of physical uplink shared channel (PUSCH) opportunities within a configured grant cycle. The UE can associate a first hybrid automatic repeat request (HARQ) process identifier (PID) setting with a first PUSCH opportunity of a first subset of the set of PUSCH opportunities, the first HARQ PID setting configured by a base station. The UE can select a second HARQ PID setting for a second PUSCH opportunity of a second subset of the set of PUSCH opportunities.
What exactly they claim (claim 1)
1. A method, comprising: detecting a set of physical uplink shared channel (PUSCH) opportunities within a configured grant cycle; associating a first hybrid automatic repeat request (HARQ) process identifier (PID) setting with a first PUSCH opportunity of a first subset of the set of PUSCH opportunities, the first HARQ PID setting configured by a base station; and selecting a second HARQ PID setting for a second PUSCH opportunity of a second subset of the set of PUSCH opportunities.
