Abstract
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.
