Apple patents method to boost 5G uplink data speeds using 8 layers

Apple has been granted a patent for a way to improve how mobile devices send data to cell towers. The invention allows phones to use eight separate data streams instead of the usual four by adjusting specific signal patterns called comb offsets and cyclic shifts.

Why it mattersThis technical update could help future phones handle heavier data uploads, such as live video streaming or large file transfers, by making the connection between the device and the network more efficient.

In the filing’s own words

Embodiments herein provide sounding reference signals (SRS) enhancements to support more than four layers of codebook based uplink operation (e.g., 6 and 8 layer uplink operation). To support 6 and 8 layer SRS uplink operation, some embodiments herein use multiple SRS Comb offsets. Some embodiments propose an increase maximum number of SRS cyclic shifts. Some embodiments use a flexible SRS cyclic shift selection.

What exactly they claim (claim 1)

1. A method for a UE, the method comprising: receiving a transmission from a network node including configuration details for sounding reference signals (SRS) for eight ports, wherein the configuration details map the eight ports to multiple comb offsets and one or more cyclic shifts, encoding SRS transmissions for the eight ports according to the configuration details; and sending, to the network node, the SRS transmissions via the eight ports, wherein the SRS transmissions are orthogonally transmitted using the multiple comb offsets and the one or more cyclic shifts, wherein the SRS transmissions are sent using comb 4, wherein the SRS transmission is sent using two comb offsets that are equally spaced, and using equally spaced cyclic shifts within the two comb offsets, wherein each comb offset is used by four of the eight ports.
