Abstract
In one aspect, a method comprises: reconfiguring a front end circuit of a device from a first mode having a receiver radio frequency (RF) signal processing path with a first relative order into a second mode having the receiver RF signal processing path with a different relative order; determining that a timeout period has completed; and reconfiguring the front end circuit from the second mode to the first mode in response to determining that the timeout period has completed.
Claims21
A non-transitory storage medium comprising instructions that, when executed, cause a device to perform a method comprising:
- reconfiguring a front end circuit of the device from a first mode having a receiver radio frequency (RF) signal processing path with a first relative order into a second mode having the receiver RF signal processing path with a different relative order;
- determining that a timeout period has completed;
- and
- reconfiguring the front end circuit from the second mode to the first mode in response to determining that the timeout period has completed.
The non-transitory storage medium of claim 2, wherein the timeout period comprises a first dwell time, and the method further comprises:
- initializing the first dwell time to an initial predetermined value;
- and
- dynamically updating the first dwell time based on operation of the device.
A method comprising:
- operating a front end circuit of a wireless device in a bypass mode in which a receiver radio frequency (RF) signal processing path bypasses a low noise amplifier (LNA);
- determining that a timeout period has completed;
- and
- reconfiguring the front end circuit from the bypass mode to one of a first mode or a second mode in response to determining that the timeout period has completed, wherein in the first mode and in the second mode the receiver RF signal processing path comprises the LNA.
A wireless device comprising:
- a radio frequency (RF) front end circuit comprising:
- a receive path to receive, process and output a receive RF signal, the receive path comprising a low noise amplifier (LNA);
- switching circuitry coupled to the transmit path and the receive path;
- and
- a control circuit coupled to the switching circuitry, the control circuit to control the switching circuitry to configure the receive path for operation in one of a plurality of modes;
- and
- a controller coupled to the RF front end circuit, wherein the controller is to cause the receive path to be dynamically reconfigured from a first mode to a second mode based at least in part on a first dwell time maintained in at least one timer, wherein the controller is to dynamically adapt the first dwell time according to a self-learning process.
