Abstract
Embodiments of systems and methods for providing wideband transmission co-existence are generally described herein. Other embodiments may be described and claimed.
Claims20
A method to communicate using wideband transmissions, comprising:
- scanning odd numbered channel blocks of an unlicensed national information infrastructure 3 (UNII-3) band for traffic;
- determining that the odd numbered channel blocks are idle;
- transmitting data in a contiguous wideband basic service set (BSS) across even numbered channel blocks of a UNII-2 extended band and even numbered channel blocks of the UNII-3 band;
- selecting a primary channel from the UNII-2 extended band;
- and
- receiving a beacon over the UNII-2 extended band from a legacy device, wherein the legacy device joins the contiguous wideband BSS operating over the even numbered channel blocks of the UNII-2 extended band.

A method to provide wideband transmissions in a legacy network, comprising:
- scanning odd numbered channel blocks of an unlicensed national information infrastructure 3 (UNII-3) band for traffic;
- determining that the odd numbered channel blocks are idle;
- transmitting request to send (RTS) frames over even numbered channel blocks of a UNII-2 extended band and the odd numbered channel blocks of the UNII-3 band;
- receiving clear to send (CTS) frames over the even numbered channel blocks of the UNII-2 extended band and the odd numbered channel blocks of the UNII-3 band;
- transmitting data in contiguous wideband mode over the even numbered channel blocks of the UNII-2 extended band and even numbered channel blocks of the UNII-3 band;
- and
- receiving acknowledgement (ACK) frames over the even numbered channel blocks of the UNII-2 extended band and the odd numbered channel blocks of the UNII-3 band.
4 more elements
A system to provide wideband transmissions in a legacy network, comprising:
- an antenna;
- a processor configured to determine if channel blocks in an unlicensed national information infrastructure (UNII) band are idle;
- and
- a wireless communication unit configured to:
- scan odd numbered channel blocks of an UNII-3 band for traffic;
- transmit request to send (RTS) frames over even numbered channel blocks of a UNII-2 extended band and odd numbered channel blocks of the UNII-3 band;
- receive clear to send (CTS) frames over the even numbered channel blocks of the UNII-2 extended band and the odd numbered channel blocks of the UNII-3 band;
- transmit data in contiguous wideband mode over the even numbered channel blocks of the UNII-2 extended band and even numbered channel blocks of the UNII-3 band;
- and
- receive acknowledgement (ACK) frames over the even numbered channel blocks of the UNII-2 extended band and the odd numbered channel blocks of the UNII-3 band.
