AUTOMATIC GAIN CONTROL GAIN ADJUSTMENT
First Claim
1. A method of Automatic Gain Control (AGC) gain adjustment by a wireless device, the method comprising:
- receiving a primary reference signal from a primary cell operating in licensed spectrum;
determining whether a signal from a secondary cell operating in unlicensed spectrum is received; and
if the signal from the secondary cell is not received, adjusting the AGC gain for the secondary cell based on the primary reference signal and at least one of a transmission power difference, a reception power difference, and a propagation path loss difference between the primary cell and the secondary cell.

Abstract
A method of Automatic Gain Control (AGC) gain adjustment by a wireless device, including receiving a reference signal and data from a secondary cell operating in unlicensed spectrum; and adjusting the AGC gain for the secondary cell based on the reference signal, which is received in a same measurement timing configuration period as the data. Further, a method of AGC gain adjustment including receiving a primary reference signal from a primary cell operating in licensed spectrum; and adjusting the AGC gain for a secondary cell operating in unlicensed spectrum based on the primary reference signal and at least one of a transmission power difference, a reception power difference, and a propagation path loss difference between the primary cell and the secondary cell.

15. A wireless communication device, comprising:
-
a tuner configured to receive a primary reference signal from a primary cell operating in licensed spectrum; a circuit configured to determine whether a signal from a secondary cell operating in unlicensed spectrum is received; and an automatic gain control (AGC) circuit configured to, if the signal from the secondary cell is not received, adjust the AGC gain for the secondary cell based on the primary reference signal and at least one of a transmission power difference, a reception power difference, and a propagation path loss difference between the primary cell and the secondary cell. - View Dependent Claims (16)
