Radio access technology co-existence using adaptive energy detection
First Claim
1. A method of wireless communication, comprising:
- receiving, by a first modem operating according to a first radio access technology (RAT), a message from at least one network entity operating according to the first RAT, wherein the received message is detected by the first modem at a measured energy level;
receiving, by the first modem, a subsequent message from one of the at least one network entity or a distinct network entity different from the at least one network entity operating according to the first RAT;
sending, from the first modem to a second modem operating according to a second RAT different from the first RAT, a detected energy level value based at least on the measured energy level of the received message, wherein the subsequent message is detected by the first modem at a subsequent measured energy level, and the detected energy level value is determined based on the measured energy level of the received message and the subsequent measured energy level of the subsequent message; and
adjusting an energy detection threshold based on the detected energy level value received from the first modem.

Abstract
The disclosure provides for a method of interference detection using adaptive energy detection in unlicensed spectrum. The method can include a first modem operating according to a first radio access technology (RAT) receiving a message from a network entity operating according to the first RAT. The first modem sends a detected energy level value to a second modem that is using a second RAT, where the detected energy level value is based at least on the measured energy level of the received message. The second modem adjusts an energy detection threshold based on the detected energy level value received from the first modem. In an aspect, the first modem receives messages from a plurality of network entities operating according to the first RAT, where the detected energy level value is determined based on measured energy levels of the plurality of received messages.
