  • the basic element that needs to be defined in order to be able to operate in this band is:

  • the channelization for 6 GHz band facilitates the channelization in the 6 GHz band while considering the aforementioned incumbent services.
  • Channelization provides a definition of various channels within a band. For example, channelization correlates channel indices with specific channel size.
  • a 6 GHz band may be divided based on the frequency bandwidth.
  • the 6 GHz band may provide indices for various channel bandwidths such as 20 MHz, 40 MHz, 80 MHz, and 160 MHz channels based on assigned indices.
  • the channelization for 6 GHz band may impose one or more limitations on the channelization of a 6 GHz band.
  • the channelization for 6 GHz band may omits using the 20 MHz channel and the 40 MHz channel. Removing 20 MHz and 40 MHz channels may reduce the chance that two channels overlapped in a narrowband.
  • the channelization for 6 GHz band may define a 6 GHz channelization using 80 MHz, 160 MHz and 320 MHz and not using 20 MHz and 40 MHz. Defining the 6 GHz channelization using higher bandwidths results in lowering of the power density because energy has to be distributed along available bandwidth. Looking at every 1 MHz, the power will be lower, therefore, lower chance of interfering with neighboring bands, in this case lower chance of interfering with incumbent services that are existing currently in the 6 GHz band. Another reason for not using a 20 MHz channel and a 40 MHz channel is the high throughput requirements for Wi-Fi devices using the 6 GHz band. In that case 20 MHz channels and 40 MHz channels may not be useful because they have lower bandwidth.
  • the channelization for 6 GHz band may facilitate sliding of the 80/160/320 MHz channels to avoid incumbents. If IEEE 802.1 lax operates on the new band of 6 GHz, only the primary 80 MHz will be used. There will be no primary 20 MHz or primary 40 MHz.
  • a database may be defined to include the bands used by incumbents. This database tells AP which channel is used by the incumbent.
  • the database could be maintained by a network operator.
  • the AP may communicate with the database by sending messages to request information associated with channel allocation for incumbent services before making decisions of allocating resources to Wi-Fi devices. This communication between the AP and the database could be periodic or happen at predetermined times or requested by a system administrator.
  • a channelization for 6 GHz band may define the channel numbers for the 6 GHz band, which starts at 5935 MHz and ends at 7125 MHz, starting at index 1, in order to have sufficient values in 1 octet (255 values) to signal all possible channels. This however creates some overlap with the channel numbers used at 5 GHz.
  • a channelization for 6 GHz band may make the increment between 2 values in the channel numbers to be 10 MHz instead of 5 MHz, so that the range of channel numbers can span much higher in frequency above 7 GHz.
  • a channelization for 6 GHz band may define a new operating class for the channels at 6 GHz and use the operating class field, which is used in Annex E tables to know the regulatory rules and derive the channel starting frequency of a particular channel number, together with the channel number to derive the channel center frequency.
  • the STA can derive the center frequency and the bandwidth of the channel.
  • the operating class context may be known when identifying a channel number.

  • the country element includes a pair of operating classes (one for the first segment and one for the second segment).
  • a channelization for 6 GHz band may define the operating class in 5 GHz for the first segment and the operating class in 6 GHz for the second segment.

Abstract

La présente invention concerne des systèmes, des procédés et des dispositifs associés à un découpage en canaux de bande de 6 GHz. Un dispositif peut déterminer une attribution de fréquence sur la base d'un découpage en canaux de bande de 6 gigahertz (GHz), le découpage en canaux de 6 GHz comprenant : une ou plusieurs attributions de fréquence associées à une ou plusieurs bandes passantes, la ou les attributions de fréquence étant représentées par un ou plusieurs indices de fréquence. Le dispositif peut provoquer l'envoi d'un indice de fréquence associé à l'attribution de fréquence à un dispositif de station d'un ou de plusieurs dispositifs de station, l'indice de fréquence étant basé sur au moins l'une de la première bande passante, de la deuxième bande passante ou de la troisième bande passante.
