Abstract
In some examples, a wireless device includes a multiple-input, multiple-output (MIMO) transceiver that has a plurality of antennas to perform MIMO wireless communication. At least one processor is configured to concurrently perform discovery of respective different wireless devices using at least two of the plurality of antennas.
Claims20
A wireless device comprising:
- a multiple-input, multiple-output (MIMO) transceiver comprising a plurality of antennas;
- and
- at least one processor configured to:
- concurrently perform discovery of respective different wireless devices using at least two antennas of the plurality of antennas by using a first antenna of the at least two antennas to discover a first wireless device of the different wireless devices, and using a second antenna of the at least two antennas to discover a second wireless device of the different wireless devices;
- use, concurrently with the performing of the discovery of at least one of the respective different wireless devices using at least one of the at least two antennas and prior to association of the wireless device with any wireless network, at least one of the other of the plurality of antennas to acquire information about services provided by a wireless network, wherein acquiring information about the services provided by the wireless network is part of a task different from network discovery;
- and
- use the MIMO transceiver to perform single-input, single-output (SISO) operations prior to association of the wireless device with the wireless network.

A method of a wireless device, comprising:
- performing concurrent scanning for different wireless devices using respective individual SISO transceivers of a multiple-input, multiple-output (MIMO) transceiver by using a first SISO transceiver of the individual SISO transceivers to scan for a first wireless device of the different wireless devices, and using a second SISO transceiver of the individual SISO transceivers to scan for a second wireless device of the different wireless devices;
- concurrently with the scanning for at least one of the different wireless devices using at least one of the respective individual SISO transceivers, using at least one of the other of the individual SISO transceivers to acquire information about services provided by a wireless network, wherein acquiring information about the services provided by the wireless network is part of a task different from network discovery;
- and
- using the MIMO transceiver to perform single-input, single-output (SISO) operations prior to association of the wireless device with the wireless network.

A non-transitory machine-readable storage medium storing instructions that upon execution cause a wireless device to:
- concurrently perform different tasks using respective individual SISO transceivers of a multiple-input, multiple-output (MIMO) transceiver, the different tasks comprising sending queries according to different protocols,
- wherein the different tasks comprise wireless network discovery to discover a first wireless network using a first SISO transceiver of the individual SISO transceivers, wireless network discovery to discover a second wireless network using a second SISO transceiver of the individual SISO transceivers, and sending, using at least one of the other of the individual SISO transceivers, a Generic Advertisement Service (GAS) query or an Access Network Query Protocol (ANQP) request to obtain information of a network service provided by a wireless network;
- and
- use the MIMO transceiver to perform single-input, single-output (SISO) operations prior to association of the wireless device with the wireless network.
