Apple patents method for phones to adjust signal reports to cell towers

This patent describes a way for a phone to manage how it reports signal quality to a cell tower. The phone receives two different sets of instructions for these reports and chooses which one to use based on a specific mode or a signal from the tower.

Why it mattersThis is a technical update to how phones and cell towers communicate, likely aimed at improving connection stability or efficiency in complex network environments.

In the filing’s own words

Some aspects of this disclosure relate to apparatuses and methods for supporting channel state information (CSI) report configuration for network spatial elements adaptation. The UE can receive a CSI report configuration from the base station indicating a first configuration to configure a first CSI report, and a second configuration to configure a second CSI report. The UE can determine one or more active configurations selected from the first configuration and the second configuration, based on whether one or more of the first configuration or the second configuration is activated by a Medium Access Control (MAC) Control Element (MAC CE) or triggered by a Downlink Control Information (DCI). The processor can be further configured to select, based on a report mode, one or more CSI reports from the first CSI report and the second CSI report. The report mode can be a basic mode or an enhanced mode.

What exactly they claim (claim 1)

1. A user equipment (UE), comprising: a transceiver configured to enable wireless communication with a base station in a wireless communication system; and a processor communicatively coupled to the transceiver and configured to: receive a Channel State Information (CSI) report configuration indicating a first configuration to configure a first CSI report and a second configuration to configure a second CSI report, wherein the first configuration indicates a first CSI report type indicating time-domain attributes for the first CSI report and a first CSI reference signal (CSI-RS) resource to be monitored to generate the first CSI report, and the second configuration indicates a second CSI report type for the second CSI report and a second CSI-RS resource to be monitored for the second CSI report; determine one or more active configurations selected from the first configuration and the second configuration, based on whether one or more of the first configuration or the second configuration is activated by a Medium Access Control (MAC) Control Element (MAC CE) or triggered by a Downlink Control Information (DCI); select, based on a report mode, one or more CSI reports from the first CSI report and the second CSI report; monitor CSI-RS resources based on the one or more selected CSI reports to perform CSI-RS measurements configured by the one or more active configurations; generate the one or more selected CSI reports based on the CSI-RS measurements; and transmit the one or more selected CSI reports to the base station.
