Filed:

Jul 30, 2008

Appl. No.:

12/220951

Inventors:

Jie Gao - Sunnyvale CA, US

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04B 7/00

US Classification:

455 412, 4555521, 455 631, 455 88, 370337

Abstract:

Techniques are described that can be used to perform one or more of the following actions in order to reduce signal interference between WLAN and BlueTooth radios that are proximate to one another. One action is to selectively reduce a filter bandwidth in a WLAN radio applied to a received WLAN radio signal to reduce BlueTooth signal interference. An additional or alternative action is to selectively indicate a WLAN radio channel bandwidth larger than a channel bandwidth used for the WLAN radio so that the BlueTooth radio avoids transmitting over the indicated channel bandwidth. An additional or alternative action is to selectively reduce BlueTooth transmitter power in response to antenna isolation between BT and WLAN radio being less than a first threshold in order to reduce the likelihood of WLAN radio front end saturation.

International Classification:

H04B 17/00
H04K 3/00

US Classification:

455 6713, 455 7, 455 412

Abstract:

Embodiments may comprise logic such as hardware and/or code to adaptively control the transmission power for a wireless channel. In many embodiments, adaptively controlling the transmission power may reduce or, in some embodiments, minimize interference between the wireless display (WiDi) transmissions and other transmissions such as multimedia content streaming over another wireless channel to the notebook via a second generation (2G) channel, third generation (3G) channel, or a future long term evolution (LTE) channel.

Appl. No.:

12/960614

Inventors:

Jie Gao - Sunnyvale CA, US
Xintian Lin - Palo Alto CA, US
Qinghua Li - San Ramon CA, US

International Classification:

H04L 12/26

US Classification:

370252

Abstract:

Techniques are disclosed that involve communicating in bursty noise environments. For instance, a source device may send a probing packet to a destination device. This probing packet is for determining whether the communications medium (e.g., one or more frequency channels) is currently exhibiting a busy or jammed (e.g., due to bursty noise) condition. More particularly, based on whether an acknowledgment of the probing packet is received, the source device determines whether the channel is jammed (or busy) or clear. For example, an unacknowledged probing packet indicates that the channel is jammed or busy, while an acknowledged probing packet indicates that the channel is clear. If the channel is determined to be clear, then the source device may transmit one or more data packets to the destination device. Such data packet transmissions may be in accordance with a non rate-adaptive technique.
