Method and system for supporting incompatible channelization of a wireless communications system

摘要

A method of supporting incompatible channelization in a wireless communications system is provided. A coordinating device determines a first set of physical parameters of a first wireless channel. The first set of physical parameters includes a channel bandwidth, a central frequency, a transmit power limit, and a modulation and coding scheme. The coordinating device establishes communication with a first set of communications devices over the first wireless channel. The coordinating device then broadcasts a channel-adjustment message and determines a protection period. The channel-adjustment message comprises a set of instructions on how to adjust to a second set of physical parameters of a second wireless channel. A second set of communications devices adjust physical parameters based on the channel-adjustment message. Finally, the coordinating device communicates with the second set of communications devices over the second wireless channel during the protection period.

主权项

1. A method, comprising:
determining a first set of physical parameters of a first channel by a coordinator in a wireless communication system; establishing communication with a first set of devices over the first channel, wherein the whole first channel is used by the first set of devices to transfer data; determining a protection period in accordance with a pre-determined rule; broadcasting a channel-adjustment message, wherein the channel-adjustment message comprises a set of instructions for indicating how to adjust from the first channel to a second channel, and the set of instructions comprise channel bandwidth information for indicating how to adjust to a bandwidth of the second channel, and central frequency information for indicating how to adjust to a central frequency of the second channel; and communicating with a second set of devices over the second channel during the protection period, wherein the whole second channel is used by the second set of devices to transfer data; wherein the communication over the first channel and the communication over the second channel during the protection period are compliant with a same communication standard within the same wireless communication system.
