Method and system for Bluetooth low power link layer connection setup
First Claim
1. A method of processing a plurality of signals, the method comprising:
- performing by circuitry in a mobile device;
detecting an out-of-band blocking signal;
determining at least one of a cadence or a periodicity of said out-of-band blocking signal based on a measured received signal strength indicator (RSSI); and
managing a packet transmission duration for an associated link layer in-band connection based on said at least one of said cadence or said periodicity for said out-of-band blocking signal that was determined.

Abstract
A mobile device such as a Bluetooth low energy (BLE) device detects out-of-band blocking signals and manages packet transmission in associated BLE link layer connections based on the detected out-of-band blocking signals. The BLE device is operable to measure out-of-band RSSI to detect out-of-band transmission interferences. The BLE device compares the measured out-of-band RSSI with an out-of-band energy profile such as a LTE energy profile or a WiMAX energy profile to determine the out-of-band blocking signals indicating cadence or periodic out-of-band traffic activities. A remote BLE deice (advertiser) aperiodically or periodically transmits an advertising packet to the BLE device for a specific link layer connection. If not connected within a determined time period, the remote BLE device (advertiser) reduces transmission power for transmitting the advertising packet. The BLE device receives the advertising packet and sends a connection request packet to the remote BLE device (advertiser).
