SPR as a criterion to determine the frequencies that would be allocated for inter-band carrier aggregation, intra-band carrier aggregation, or dynamic spectrum sharing

Methods and systems are provided for using antenna sector power ratio (SPR) to determine dynamic spectrum sharing. Frequency bands associated with a cell site can support at least one wireless communication protocol. In some embodiments, a plurality of frequency bands for a plurality of cell sites are identified. SPR values for each frequency band may be determined, and a frequency band having the lowest SPR value may be identified. For example, a frequency band having a lower SPR value that is also below a particular threshold may be assigned a wireless communication protocol that was previously assigned to another frequency band having a higher SPR value. Based on assigning the frequency band another wireless communication protocol, a user device may be provided resources via that wireless communication protocol.
