Definitions

  • the present application relates generally to wireless communications, and more specifically to systems, methods, and devices for narrowband channel selection in a wireless communication network.
  • communications networks are used to exchange messages among several interacting spatially-separated devices.
  • Networks may be classified according to geographic scope, which could be, for example, a metropolitan area, a local area, or a personal area. Such networks would be designated respectively as a wide area network (WAN), metropolitan area network (MAN), local area network (LAN), wireless local area network (WLAN), or personal area network (PAN).
  • WAN wide area network
  • MAN metropolitan area network
  • LAN local area network
  • WLAN wireless local area network
  • PAN personal area network
  • Networks also differ according to the switching/routing technique used to interconnect the various network nodes and devices (e.g. circuit switching vs. packet switching), the type of physical media employed for transmission (e.g. wired vs. wireless), and the set of communication protocols used (e.g. Internet protocol suite, SONET (Synchronous Optical Networking), Ethernet, etc.).
  • SONET Synchronous Optical Networking
  • the AP 104 may transmit one NDP on CHI at time to, another NDP on CH2 at time ti, and continue to transmit one NDP on one channel through times t 2 , t3, t 4 , t 5 , t 6 , and t 7 .
  • the AP 104 may transmit one NDP on CHI at time to, another NDP on CH2 at time ti, and continue to transmit one NDP on one channel through times t 2 , t3, U, ts, te, and t 7 to periodically change the primary channel of the AP 104.
  • the STAs that may be associated with the AP 104 may be informed of the position of the primary channel.
  • the switching of the primary channel may be conveyed to the STAs by the AP 104 as a schedule provided at association or later through a management exchange with the STAs.
  • This information may be included in a beacon signal.
  • IEEE (Extended) Channel Switch Announcement frames or elements may be used to indicate the switch from one channel to another. Elements may be enhanced by including information on further future channel switches as well.
  • the AP 304 may be configured to only receive messages on a primary channel, and may not be configured to receive messages on other channels at the same time as it is listening to the primary channel.
  • the AP 304 may then lock a secondary channel by transmitting on the channel, for example.
  • the AP 304 may then receive a message on another channel, such a primary channel, from the first STA 306a requesting to communicate with AP 304 on a particular channel, such as the locked secondary channel.
  • the AP 304 may then stop transmitting on the secondary channel, thereby unlocking the secondary channel, and begin communications with the first STA 306a on the secondary channel.
  • the acknowledgement message may acknowledge receipt of the configuration message from the first STA 306a by the AP 304 and/or indicate that the channel selected by the first STA 306a is available for wireless communication. Further, the acknowledgment message may be used to set NAVs and reserve a channel, such as to reserve the channel selected by the first STA 306a for communication between the AP 304 and first STA 306a.
  • the CTS packet may thus provide protection against hidden nodes and avoid other STAs transmitting in the primary channel during a time in which the AP 304 may not be listening to the primary channel.
  • the first STA 306a may defer transmission of data on the selected channel (e.g., CH3 at time t3 in FIG.
  • the AP 304 may not wait for a channel switching time, as illustrated in communication timeline 1000 of FIG. 10.
  • Channel(s) TBD bits Indicates that contention is allowed only in the indicated channel(s) for the time of this RAW; Channels may be indicated by listing the Channel ID number as defined by the regulatory domain or may be indicated by a relative index identifying the channel position within the BSS operating bandwidth.
  • the AP 304 may periodically transmit channel indication messages 504a, 504b on a first 2 MHz channel corresponding to line 502a.
  • the STAs near the AP 304 may have previously received one or more messages from the AP 304 on the first 2 MHz channel, a second 2 MHz channel, a third 2 MHz channel, and a fourth 2 MHz channel, corresponding to lines 502a, 502b, 502c, 502d, respectively.
  • the STAs may have estimated the quality of the four different 2 MHz channels and selected the channel with the highest quality for communication based on the estimated quality of each channel.
  • the STAs may await a channel indication message from the AP 304 to determine available channels for wireless communication and when the available channels are available.
