Problems solved by technology

[0003] Because each frequency band can be implemented as a separate radio (i.e., each with one or more antennas and associated circuitry), simultaneously idling to listen to channels on multiple frequency bands increases the reliability of non-access point (AP) stations (STAs). power consumption

Embodiment Construction

[0031] A multi-band communication device is capable of sending and receiving data on a number of different frequency bands in a wireless network. These electronic devices have many advantages over conventional electronic devices capable of operating in a single frequency band. However, there are many technical problems in operating a multi-band communication device in a wireless network. For the avoidance of doubt, in the following description, "multi-band transmission" refers to concurrent communications on multiple channels on multiple frequency bands.

[0032] For example, since each frequency band can be implemented as a separate radio (i.e., each with one or more antennas and associated circuitry), idling listening to channels on multiple frequency bands simultaneously increases the burden on non-access point (AP) stations ( STA) power consumption. Accordingly, example embodiments seek to reduce idle listening power consumption of multi-band non-AP STAs and other techni...

Abstract

A multi-band communication device includes: one or more transceiver circuits, each of which in operation transmits and receives data on a plurality of channels in different frequency bands; and a band configuration circuitry operative to change a configuration of any one of the transceiver circuits based on configuration information received from a multi-band Access Point (AP). The configuration information specifies one of the frequency bands as a Primary band and the other frequency bands as Secondary band(s). The transceiver circuitry operating on the Primary band is used as a default circuitry for communication with the AP.

Description

technical field [0001] The present disclosure generally relates to multiband communication devices, multiband access points, and communication methods for multiband transmission, and more particularly, to multiband communication devices operating on multiple frequency bands in a wireless network. Background technique [0002] Wireless networks that provide multi-band communication enable electronic devices to communicate on a number of different frequency bands. This type of network has advantages over other wireless networks where wireless communication is limited to a single frequency band. [0003] Because each frequency band can be implemented as a separate radio (i.e., each with one or more antennas and associated circuitry), simultaneously idling to listen to channels on multiple frequency bands increases the burden on non-access point (AP) stations (STAs). power consumption. Therefore, it is desirable to reduce idle listening power consumption of multi-band non-AP S...
