Patent drawing
Patent drawing from the official filing.

Apple describes a method for phones to tell a network which frequency bands they can use to send data. The phone then follows instructions to switch between up to four different bands to maintain a stable connection.

Why it mattersThis is a standard technical improvement to help phones maintain a strong signal when sending data, particularly in areas with weak reception.

In the filing’s own words

A user equipment (UE configured to configure transceiver circuitry to transmit UE capability information related to uplink (UL) transmission (Tx) switching to a network, wherein the UE capability comprises an indication that the UE supports two or more supplementary uplink (SUL) bands or carriers, decode, from signaling received from the network, a UL Tx switching configuration based on at least the UE capability information, wherein the UL Tx switching configuration comprises one of 3 configured bands or 4 configured bands and perform UL transmissions based on the UL Tx switching configuration.

What exactly they claim (claim 1)

1. An apparatus of a user equipment (UE), the apparatus comprising processing circuitry configured to: configure transceiver circuitry to transmit UE capability information related to uplink (UL) transmission (Tx) switching to a network, wherein the UE capability comprises an indication that the UE supports two or more supplementary uplink (SUL) bands or carriers; decode, from signaling received from the network, a UL Tx switching configuration based on at least the UE capability information, wherein the UL Tx switching configuration comprises one of 3 configured bands or 4 configured bands; and perform UL transmissions based on the UL Tx switching configuration.
