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
in response to a determination that 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.
