System and method for carrier aggregation IMD control

摘要

Methods and devices are described for managing the use of system resources in a wireless network. In one aspect, a method is performed by a wireless network system associated with a wireless network. The method provides upstream communications from an electronic device to the wireless network. The method includes: identifying a set of carriers that may be used together without causing an intermodulation product that falls within one or more active pass-bands associated with a receiver of the electronic device; and scheduling a carrier aggregated upstream communication from the electronic device to the wireless network using the identified set of carriers, the carrier aggregated upstream communication being an orthogonal frequency division multiplexing communication.

1. A method, performed by a wireless network system associated with a wireless network, the method comprising:
identifying one or more sets of carriers that, when used together, do not generate an intermodulation product that falls within one or more active pass-bands associated with a receiver of an electronic device by:
selecting two bands, each band being associated with a plurality of upstream carriers to use for upstream communications within said band, the upstream communication being an orthogonal frequency division multiplexing communication;for a plurality of pairs of upstream carriers that consists of one upstream carrier from each band:
calculating a third order intermodulation product;determining whether the third order intermodulation product falls within the active pass-band, the active pass-band representing receiver channels corresponding to transmitter channels that would be in use for transmissions using a selected set of carriers;categorizing a pair of upstream carriers as an intermodulation-friendly carrier pair or an intermodulation-unfriendly carrier pair based on the determination as to whether the third order intermodulation product falls within the active pass-band; andstoring categorization information in memory based on the categorizing.
