Samsung patents method for prioritizing data in mobile uplink channels
This patent describes a way for mobile devices to send two types of confirmation signals at the same time over a single data channel. It ensures that high-priority confirmations are placed in specific parts of the signal to avoid interference from reference markers used for signal quality.
In the filing’s own words
A system and method for multiplexing uplink communications. In some embodiments, the method includes: multiplexing, by a User Equipment (UE) a Low Priority (LP) Hybrid Automatic Repeat Request acknowledgment (HARQ-ACK) codebook and a High Priority (HP) HARQ-ACK codebook in a first Physical Uplink Shared Channel (PUSCH), the multiplexing including mapping the HP HARQ-ACK codebook after a first symbol that follows a Demodulation Reference Signal (DMRS) and that does not include any DMRS Resource Elements (REs).
What exactly they claim (claim 1)
1. A method, comprising: multiplexing, by a User Equipment (UE) a Low Priority (LP) Hybrid Automatic Repeat Request acknowledgment (HARQ-ACK) codebook and a High Priority (HP) HARQ-ACK codebook in a first Physical Uplink Shared Channel (PUSCH), the multiplexing comprising: mapping the LP HARQ-ACK codebook from a first PUSCH symbol that does not include any Demodulation Reference Signal (DMRS) Resource Elements (DMRS REs); and mapping the HP HARQ-ACK codebook after a first symbol that follows a DMRS symbol and does not include any DMRS REs; determining, by the UE, that the LP HARQ-ACK codebook has a payload with a size greater, by n bits, than a first threshold; and dropping, by the UE, n bits of the payload of the LP HARQ-ACK codebook.
