Apple patents method to prioritize urgent data in wireless signals
Apple has been granted a patent for a method that helps mobile devices send different types of control data to cell towers with varying levels of importance. The system assigns different error-correction strengths to high-priority and low-priority information, ensuring critical signals get through first.
In the filing’s own words
Systems and methods for modularized design for inter-physical layer priority uplink control information (UCI) multiplexing are disclosed herein. A user equipment (UE) may determine a first code rate for a first portion of UCI and a second code rate for a second portion of UCI. Different code rates may be used to encode different portions of UCI (e.g., hybrid automatic repeat request acknowledgement (HARQ-ACK) bits, channel state information (CSI) reporting bits, scheduling request (SR) bits, cyclic redundancy check (CRC) bits, etc.). Further, a UE may select a group of bets offset sets based on a physical layer priority type and a UCI multiplexing type.
What exactly they claim (claim 1)
1. A method of a user equipment (UE), comprising: encoding one or more high priority (HP) hybrid automatic repeat request acknowledgement (HARQ-ACK) bits into a first portion of uplink control information (UCI) at a first code rate r 1; encoding one or more low priority (LP) HARQ-ACK bits into a second portion of the UCI at a second code rate r 2; determining a first rate matching output sequence length for the first portion of the UCI based on a number of the HP HARQ-ACK bits and a number of HP scheduling request (SR) bits of the first portion of the UCI; and transmitting the UCI to a base station in a physical uplink control channel (PUCCH).
