Method and system for addressing interference between co-existing radios of differing radio access technologies

摘要

Methods and systems for addressing interference between co-existing radios of differing radio access technologies (RATs) are provided. One RAT radio send an indication to a second RAT radio when it is transmitting, but does so after determining there is an actual likelihood that the first RAT transmission will interfere with reception by the second RAT radio. Optionally, the second RAT radio makes its own determination of whether there is a likelihood of interference, and ignores the indication if it is determined interference is not likely. Alternatively, the second RAT radio sends an indication to the first RAT radio when it is receiving, only after determining there is a likelihood that first RAT transmissions will interfere with reception by the second RAT radio.

1. A method in a device comprising a first RAT (radio access technology) radio and a second RAT radio, the method comprising:
determining whether or not a transmission from the first RAT radio is expected to cause interference to reception by the second RAT radio based on at least one interference criterion; when it has been determined that the transmission from the first RAT radio is expected to cause interference to reception by the second RAT radio, transmitting an indication from the first RAT radio to the second RAT radio to indicate that the first RAT radio is transmitting; if the second RAT radio is operating on a potentially effected frequency, adjusting receiver processing when the indication from the first RAT radio to the second RAT radio to indicate that the first RAT radio is transmitting is received; if the second RAT radio is not operating on a potentially effected frequency when the indication from the first RAT radio to the second RAT radio to indicate that the first RAT radio is transmitting is received, ignoring the indication.
