Filed: 2003-10-24
Abstract: Channel estimation and spatial processing for a TDD MIMO system. Calibration may be performed to account for differences in the responses of transmit/ receive chains at the access point and user terminal (512). During normal operation, a MIMO pilot is transmitted on a first link (522) and used to derive an estimate of the first link channel response (524), which is decomposed to obtain a diagonal matrix of singular values and a first unitary matrix containing both left eigenvectors of the first link and right eigenvectors of a second link (526). A steered reference is transmitted on the second link using the eigenvectors in the first unitary matrix (530), and is processed to obtain the diagonal matrix and a second unitary matrix containing both left eigenvectors of the second link and right eigenvectors of the first link (532).

Title: Soft handoff with interference cancellation in a wireless frequency hopping communication system
Inventor: AGRAWAL AVNEESH
IPC: H04B7/26
Filed: 2004-05-07
Abstract: Techniques are provided to support soft handoff in a frequency hopping OFDMA system (120x). Each sector (104a, 104b, 104c) 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 (104a, 104b, 104c) simultaneously. Non-handoff users are assigned traffic channels by their sole sectors (104a, 104b, 104c), and soft-handoff users are assigned traffic channels by their "serving" sectors. For each sector, the traffic channels assigned to the non-handoff users are orthogonal to one another and may or may not be orthogonal to the traffic channels assigned to the soft-handoff users. Each sector (104a, 104b, 104c) processes its received signal and recovers the data transmissions from the non-handoff users of that sector. Each sector (104a, 104b, 104c) then estimates the interference (520)due to the non-handoff users and cancels the interference (530) from the received signal. Each sector further processes its interference-canceled signal to recover the data transmissions from the soft-handoff users (540a).
