Patent number: 9413601Abstract: A first network device determines whether a first reference code included in at least a first transmission on a communication channel is associated with a code configured in the first network device. The communication channel is shared among a plurality of communication networks and the first reference code is associated with a first communication network of the plurality of communication networks. The first network device joins the first communication network associated with the first reference code in response to determining the first reference code is associated with the code configured in the first network device. The first network device communicates with a second network device in the first communication network using the code configured in the first network device.Type: GrantFiled: March 15, 2013Date of Patent: August 9, 2016Assignee: QUALCOMM IncorporatedInventors: Joubin Karimi, Ehab Tahir, Brian James Langlais, John Fraser Chappel, Son Binh Cam, Richard David Roze, Gregory Allen Magin, Celestino A. Corral, Syed Adil Hussain, Keith Riley

Patent number: 9131454Abstract: A power spectral density (PSD) shape may be modified based upon the transmitter power setting of a transmitter. The power associated with notched frequencies and adjacent frequencies may be adjusted responsive to a change in transmitter power setting. As a result of adjusting the power for the notched frequencies and adjacent frequencies when operating at the different transmitter power setting, the performance of the transmission system is improved. The PSD shape may be considered dynamic, being modified responsive to a change in transmitter power setting by adjusting power associated with notches in the PSD shape based on the transmitter power setting and PSD constraint.Type: GrantFiled: March 13, 2013Date of Patent: September 8, 2015Assignee: QUALCOMM IncorporatedInventors: Brian James Langlais, Ehab Tahir, Joubin Karimi, John Fraser Chappel, Son Binh Cam, Richard David Roze

Patent number: 9077489Abstract: A tone map includes physical layer transmission properties for a multi-carrier communications channel. The physical layer transmission properties indicate modulation mode and transmission power to be used on one or more frequencies (i.e. “tones”). The transmission power may be reduced on a first frequency having a high signal-to-noise ratio (SNR) so that performance will improve for a second frequency having a lower SNR. Transmission power may be reduced on a first frequency having an unusably low SNR so that performance will improve on a second frequency. A tone map message is used to efficiently communicate modulation and transmission power adjustments on a per-carrier basis.Type: GrantFiled: March 13, 2013Date of Patent: July 7, 2015Assignee: QUALCOMM IncorporatedInventors: Ehab Tahir, Son Binh Cam, Richard David Roze, Joubin Karimi, Brian James Langlais, John Fraser Chappel, Syed Hussain, Manjunath Krishnam, Gregory Magin

Patent number: 8995247Abstract: A first network device detects at least a first orthogonal code included in a preamble of a network packet received at the first network device from a second network device in an orthogonal frequency division multiplexing (OFDM) communication network. The first network device determines whether the first orthogonal code included in the preamble is associated with an assigned orthogonal code for the first network device. The assigned orthogonal code for the first network device is orthogonal to other assigned orthogonal codes for other network devices in the OFDM communication network. An operational mode of the first network device is changed from a sleep mode to an awake mode in response to determining the first orthogonal code is associated with the assigned orthogonal code for the first network device.Type: GrantFiled: January 7, 2013Date of Patent: March 31, 2015Assignee: QUALCOMM IncorporatedInventors: John Fraser Chappel, Ehab Tahir, Richard David Roze, Brian James Langlais, Joubin Karimi
