TRANSMISSION POWER MODULATION TO FACILITATE IN-DEVICE COEXISTENCE BETWEEN WIRELESS COMMUNICATION TECHNOLOGIES
First Claim
1. A method comprising:
- determining, with a processor, a scheduled time period during which data is received by a device via Bluetooth;
reducing a transmission power of a cellular transmission from the device to a threshold level prior to the scheduled time period and controlling the transmission power so that the transmission power does not exceed the threshold level during the scheduled time period; and
subsequent to the scheduled time period, increasing the transmission power to a level exceeding the threshold level.

Abstract
A method of modulating transmission power to facilitate in-device coexistence between wireless communication technologies is provided. The method can include determining a scheduled time period during which data is received by a device via a first wireless communication technology. The method can further include reducing a transmission power of a transmission from the device via a second wireless communication technology to a threshold level prior to the scheduled time period and controlling the transmission power so that the transmission power does not exceed the threshold level during the scheduled time period. The method can additionally include, subsequent to the time period, increasing the transmission power to a level exceeding the threshold level.

13. A method comprising:
-
determining a scheduled time period during which data is received by a device via a first wireless communication technology; determining, with a processor, that a transmission power of a transmission from the device via a second wireless communication technology should be reduced to a threshold level during the scheduled time period so that transmission via the second wireless communication technology does not inhibit data reception via the first wireless communication technology during the scheduled time period; and sending a message including an indication of the scheduled time period to a control module for the second wireless communication technology in advance of the scheduled time period to request that the control module reduce the transmission power to the threshold level prior to the scheduled time period and control the transmission power so that it does not exceed the threshold level during the scheduled time period. - View Dependent Claims (14, 15, 16, 17, 18)
