Abstract

In an example, an apparatus includes first and second antennas and a switched extractor coupled to the first antenna. The switched extractor includes an extractor configured to extract an extraction frequency band, a bypass line, and switching circuitry. The switching circuitry is configured to selectively establish a bypass signal path including the bypass line or a concurrent signal path including the extractor. The apparatus also includes first and second transceiver units (TRXUs) and a processor. The first TRXU is coupled to the first antenna via the switched extractor. The second TRXU is coupled to the first antenna via the switched extractor and coupled to the second antenna. The processor is configured to cause the switching circuitry to selectively connect the first TRXU to the first antenna via the bypass or the concurrent signal path based on the extraction frequency band and an operational frequency band associated with the first TRXU.

First claim

What is claimed is:

1 . A method for enhancing antenna utilization, the method comprising:
receiving a first wireless signal at a first antenna; routing the first wireless signal from the first antenna along a concurrent signal path, including:
separating the first wireless signal into a first concurrent signal and a second concurrent signal in accordance with an extraction frequency band;
providing the first concurrent signal to a first transceiver unit configured to communicate via a wireless wide area network (WWAN); and
providing the second concurrent signal to a second transceiver unit configured to communicate via a wireless local area network (WLAN);
receiving a second wireless signal at a second antenna; providing the second wireless signal to the second transceiver unit; comparing the extraction frequency band to an operational frequency band associated with the first transceiver unit; responsive to the comparing, issuing a command to switch from the concurrent signal path to a bypass signal path based on the operational frequency band associated with the first transceiver unit corresponding to a WWAN band being adjacent to or at least partially overlapping with a WLAN band associated with the second transceiver unit; and responsive to the issuing, routing the first wireless signal from the first antenna along the bypass signal path, including providing a version of the first wireless signal to the first transceiver unit.

2 . The method of claim 1 , wherein:
the operational frequency band associated with the first transceiver unit comprises a band assignment that comports with a Long-Term Evolution (LTE) standard; and the extraction frequency band corresponds to another operational frequency band associated with the second transceiver unit.

3 . The method of claim 1 , further comprising, responsive to the issuing:
decreasing a first quantity of antennas of a first multiple-input, multiple output (MIMO) configuration corresponding to the second transceiver unit; and continuing to provide the second wireless signal to the second transceiver unit using the decreased first quantity.

4 . The method of claim 3 , further comprising:
increasing the decreased first quantity of antennas of the first MIMO configuration corresponding to the second transceiver unit, including switching to another bypass signal path for the second transceiver unit; and responsive to the switching to the other bypass signal path,
decreasing a second quantity of antennas of a second MIMO configuration corresponding to the first transceiver unit; and
routing the first wireless signal from the first antenna along the other bypass signal path, including providing another version of the first wireless signal to the second transceiver unit.
