Apple patents method for managing overlapping 5G uplink transmissions

This filing describes a way for a device to handle multiple data uploads happening at the same time on different antenna panels. It outlines how the device coordinates these overlapping signals and confirms receipt of data using specific technical rules.

Why it mattersIt improves how phones manage complex 5G data streams, ensuring reliable connections when multiple signals overlap.

In the filing’s own words

A user equipment (UE) includes a transceiver and a processor that is configured to receive multiple DCIs for simultaneous multi-panel physical up-link shared channel (PUSCH) transmissions (STxMP). The processor is configured to determine that the UE is scheduled with the STxMP overlapping in a time domain and a frequency domain by multiple physical downlink control channels (PDCCHs) having different values of an associated control resource set pool index. Based on the determination, the processor is configured to schedule each PUSCH transmission of the STxMP based on associated downlink modulation reference symbols in accord with a UE capability, multiplex two or more hybrid automatic repeat request acknowledgments (HARQ-ACKs) in accord with a total number of HARQ-ACKs described in a total downlink assignment index bit-field of each DCI of the multiple DCIs, and determine transmission of the PUSCHs based on a respective data priority or scheduling of each PUSCH of the STxMP.

What exactly they claim (claim 1)

1. A user equipment (UE), comprising: a transceiver; and a processor configured to: receive, via the transceiver, multiple DCIs for simultaneous multi-panel physical uplink shared channel (PUSCH) transmissions (STxMP); determine that the UE is scheduled with the STxMP overlapping in a time domain and a frequency domain by multiple physical downlink control channels (PDCCHs) having different values of an associated control resource set (CORSET) pool index; and in response to the determination: schedule each PUSCH transmission of the STxMP based on associated downlink modulation reference symbols (DMRSs) in accord with a UE capability; multiplex two or more hybrid automatic repeat request acknowledgments (HARQ-ACKs) in accord with a total number of HARQ-ACKs described in a total downlink assignment index (TDAI) bit-field of each DCI of the multiple DCIs; and determine transmission of PUSCHs based on a respective data priority or scheduling of each PUSCH of the STxMP.
