Abstract
Wireless receiver systems and methods for user equipment are described that employ multiple receiver heads. The multiple heads can receive wireless communication signals over different receive paths from different transmission sources. The systems can scan and monitor signal quality from all receiver heads during a scheduled gap in a communication link without interfering with an ongoing communication session.
Claims11
A circuit for wireless signal reception comprising a switching network having:
- M switches;
- N inputs connected to the M switches and configured to connect to N antenna sub-arrays;
- K outputs connected to the M switches and configured to connect to K amplifiers, where M is greater than N and K and M, N, and K are integers greater than 1, and wherein the M switches are configured to route a signal from a selected input of the N inputs to a selected output of the K outputs;
- and
- a receiver network having:
- a first amplifier having a first input to receive a first wireless communication signal from a first of the K outputs;
- a first mixer or synthesizer connected to a first output of the first amplifier;
- a second mixer or synthesizer connected to a second output of the first amplifier;
- a second amplifier having a second input to receive a second wireless communication signal from a second of the K outputs;
- a third mixer or synthesizer connected to a third output of the second amplifier;
- and
- a fourth mixer or synthesizer connected to a fourth output of the second amplifier, wherein an output of the first mixer or synthesizer and an output of the third mixer or synthesizer are connected to a first node and an output of the second mixer or synthesizer and an output of the fourth mixer or synthesizer are connected to a second node,
- wherein the first mixer or synthesizer and the fourth mixer or synthesizer are configured to operate with a first local oscillator frequency and the second mixer or synthesizer and the third mixer or synthesizer are configured to operate with a second local oscillator frequency different from the first local oscillator frequency.
