Tingfang Ji: Restrictive reuse set management. QUALCOMM Incorporated, Thomas R Rouse, Charles D Brown, Donald C Kordich, August 14, 2007: US07257406 (53 worldwide citation)

A restrictive reuse set management algorithm for equal grade of service on a forward link (FL) transmission is described. While a restrictive reuse algorithm is known to improve the SINR of weak users in interference limited networks, the fairness issue associated with restrictive reuse has not been ...

Hemanth Sampath, Tingfang Ji: Feedback to support restrictive reuse. QUALCOMM Incorporated, Sandip S Minhas, Milan I Patel, June 16, 2009: US07548752 (51 worldwide citation)

The scheduler in a base station needs CQI information from a terminal for all reuse sets every 5 ms. to decide on which re-use set to schedule a given terminal. For MIMO users, the problem is that the CQI cannot be reconstructed for all re-use sets, using the current design. Solution: (1) For Multip ...

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 ...

Tingfang Ji, Ayman Naguib, Arak Sutivong, Dhananjay Ashok Gore, Alexei Gorokhov: Channel structures for a quasi-orthogonal multiple-access communication system. QUALCOMM Incorporated, Stanton Braden, May 21, 2013: US08446892 (41 worldwide citation)

A channel structure has at least two channel sets. Each channel set contains multiple channels and is associated with a specific mapping of the channels to the system resources available for data transmission. Each channel set may be defined based on a channel tree having a hierarchical structure. T ...
