Preventing coexistence interference through smart band selection in MSMA devices

摘要

Various embodiments leverage the typical manner in which a RAT selects a supported frequency band listed in its acquisition database and the standard communications with its network indicating the supported frequency bands to avoid potential coexistence events with one or more other RATs. In particular, various embodiments include methods for avoiding band interference between RATs operating on a multi-SIM communication device by identifying the frequency bands available to each of the RATs, comparing the identified frequency bands to determine whether any RAT's frequency bands will interfere with one or more other RAT's frequency bands, and in response to determining that there is a possibility of frequency band interference, removing those interfering frequency bands from that RAT's acquisition database. As a result, during standard communications, that RAT will report to its network that it supports only non-interfering frequency bands.

1. A method for avoiding coexistence interference between radio access technologies (RATs) operating on a multi-subscription, multi-active communication device, comprising:
obtaining information regarding available frequency bands for a first RAT and a second RAT; determining whether there is a possibility of frequency band interference between the first RAT and the second RAT; configuring an acquisition database of the first RAT to include only non-interfering frequency bands, in response to determining that there is the possibility of frequency band interference between the first RAT and the second RAT; determining whether there is any band available to the first RAT that meets a quality of service threshold and that does not interfere with a current frequency band of the second RAT; and further configuring the acquisition database of the first RAT to include all frequency bands available to the first RAT, in response to determining that there is not a band available to the first RAT that meets the quality of service threshold and that does not interfere with the current frequency band of the second RAT.
