Apple patents 5G signal management for multi-antenna phones

Patent drawing
Patent drawing from the official filing.

Apple describes a method for smartphones to manage how they receive 5G signals across different frequency bands. The phone tells the network how many signal receivers it has, then adjusts its antenna settings to avoid interference between different signal streams.

Why it mattersThis is a technical improvement to how 5G phones handle multiple signal bands, likely aimed at improving connection stability in complex network environments.

In the filing’s own words

Apparatuses, systems, and methods for inter-band carrier aggregation enhancements, such as for multiple receive chain capable UEs, e.g., in 5G NR systems and beyond. A UE may indicate, to a network node, a multi-receive chain configuration of the UE, e.g., via a UE capability. The UE may determine, based on information received from the network node, that at least one of an intra-band component carrier (CC) conflict or an inter-band CC conflict is occurring on at least one receive chain of the UE and determine a receive beam restriction (e.g., a scheduling restriction and/or a measurement restriction) to avoid at least one of the intra-band CC conflict or the inter-band CC conflict for the at least one receive chain. The UE may apply the receive beam restriction to the at least one receive chain, e.g., based on the determination.

What exactly they claim (claim 1)

1. A method for receive beam restriction determination, comprising: a user equipment device (UE), indicating, to a network node, a multi-receive chain configuration of the UE; determining, based on information received from the network node, that at least one of an intra-band component carrier (CC) conflict or an inter-band CC conflict is occurring on at least one receive chain of the UE; and determining a receive beam restriction to avoid at least one of the intra-band CC conflict or the inter-band CC conflict for the at least one receive chain based, at least in part, on the multi-receive chain configuration of the UE; and applying the receive beam restriction to the at least one receive chain based on the determining.
