US 11,902,952 B2 · Carrier aggregation grouping based on user location in 5G NR massive MIMO beamforming network

Abstract

Methods, media, and systems are provided for carrier aggregation grouping based on user device location. For example, the methods, media, and systems receive one or more Synchronization Signal Block (SSB) beam reports from one or more user devices. Further, a base station divides a coverage area associated with a multiple-input multiple-output (MIMO) service into carrier aggregation (CA) groups associated with one or more component carriers. Upon receiving or determining the location of the one or more user devices associated with each of the one or more SSB beam reports, the one or more component carriers are assigned to at least one of the CA groups based on the location of the one or more user devices and the SSB beam reports. Furthermore, if interference from a neighboring base station is detected, the one or more component carriers experiencing the interference is grouped differently from the interfering carriers.
