Abstract
Systems and methods for OFDM channelization are provided that allow for the coexistence of sub-band channels and diversity channels. Methods of defining diversity sub-channels and sub-band sub-channels are provided and systematic channel definition and labeling schemes are provided.
Claims20
A method for operating a base station to communicate with one or more mobile stations, comprising:
- transmitting OFDM symbols using a plurality of sub-carriers within an OFDM band;
- the OFDM symbols collectively containing diversity channels and sub-band channels, each diversity channel utilizing a plurality of sub-carriers distributed across the OFDM band, and each sub-band channel utilizing a contiguous set of sub-carriers within the OFDM band;
- and
- at least some of the OFDM symbols simultaneously including sub-carriers utilized by a sub-band channel and sub-carriers utilized by a diversity channel.
1 more element
A base station for communicating with one or more mobile stations, the base station comprising:
- a processor coupled to a memory, the memory storing processor executable program instructions, which when executed by the processor, cause the processor to:
- transmitting OFDM symbols using a plurality of sub-carriers within an OFDM band;
- the OFDM symbols collectively containing diversity channels and sub-band channels, each diversity channel utilizing a plurality of sub-carriers distributed across the OFDM band, and each sub-band channel utilizing a contiguous set of sub-carriers within the OFDM band;
- and
- at least some of the OFDM symbols simultaneously including sub-carriers utilized by a sub-band channel and sub-carriers utilized by a diversity channel.
