Dhananjay Ashok Gore, Avneesh Agrawal, Tamer Kadous: Pilot transmission schemes for a multi-antenna system. Qualcomm Incorporated, Philip R Wadsworth, Sandip S Minhas, Penz Zhu, December 5, 2006: US07145940 (99 worldwide citation)

Efficient pilot transmission schemes for multi-antenna communication systems are described. In general, MISO receivers prefer a pilot transmitted in one spatial direction, and MIMO receivers typically require a pilot transmitted in different spatial directions. In one pilot transmission scheme, a fi ...

Avneesh Agrawal: Soft handoff with interference cancellation in a wireless frequency hopping communication system. QUALCOMM Incorporated, Kam T Tam, Charles Brown, Thomas R Rouse, August 7, 2007: US07254158 (80 worldwide citation)

Techniques are provided to support soft handoff in a frequency hopping OFDMA system. Each sector concurrently supports “non-handoff” users and “soft-handoff” users. A non-handoff user communicates with only one sector, and a soft-handoff user communicates with multiple sectors simultaneously. Non-ha ...

Avneesh Agrawal, Edward Harrison Teague: Fast frequency hopping with a code division multiplexed pilot in an OFDMA system. Qualcomm Incorporated, Thomas R Rouse, Sandip S Minhas, Dmitry R Milikovsky, February 13, 2007: US07177297 (78 worldwide citation)

Techniques are provided to support fast frequency hopping with a code division multiplexed (CDM) pilot in a multi-carrier communication system (e.g., an OFDMA system). Each transmitter (e.g., each terminal) in the system transmits a wideband pilot on all subbands to allow a receiver (e.g., a base st ...

Arak Sutivong, Avneesh Agrawal: Quasi-orthogonal multiplexing for a multi-carrier communication system. QUALCOMM Incorporated, Sandip S Minhas, Peng Zhu, May 25, 2010: US07724777 (55 worldwide citation)

For quasi-orthogonal multiplexing in an OFDMA system, multiple (M) sets of traffic channels are defined for each base station. The traffic channels in each set are orthogonal to one another and may be pseudo-random with respect to the traffic channels in each of the other sets. The minimum number of ...

Avneesh Agrawal, Edward Harrison Teague, Tingfang Ji: Soft handoff for reverse link in a wireless communication system with frequency reuse. QUALCOMM Incorporated, Thomas R Rouse, Sandip, Darren M Simon, October 14, 2008: US07437164 (50 worldwide citation)

For soft handoff on the reverse link with restrictive reuse, a wireless terminal searches for pilots transmitted by sectors in a wireless system, measures the detected pilots, selects a serving sector (e.g., the strongest received sector), and identifies non-serving sectors that may receive high int ...
