Abstract: Techniques for performing rank-dependent precoding for a MIMO transmission are described. Each rank may be associated with a set of at least one precoding vector or matrix that can provide good performance for that rank. A transmitter may obtain a precoding vector for a rank-1 transmission from a first set containing at least one column vector of a unitary matrix, e.g., a Fourier matrix. The transmitter may perform precoding for the rank-1 transmission based on the precoding vector. The transmitter may obtain a precoding matrix for a rank-2 transmission from a second set containing an identity matrix. The transmitter may perform precoding for the rank-2 transmission based on the precoding matrix. For the rank-2 transmission, the transmitter may select the identity matrix as the precoding matrix if a MIMO channel resembles a diagonal channel (which may be determined based on antenna configurations) and may select the unitary matrix otherwise.

Title: Apparatus and method for negotiating frame offset between base station and relay station in broadband wireless communication system using multi-hop relay scheme
Inventor: OH CHANG-YOON
IPC: H04B7/26
Filed: 2008-02-29
Abstract: Provided are an apparatus and method for negotiating a frame offset between a Base Station (BS) and a Relay Station (RS) in a wireless communication system using a multi-hop relay scheme. A communication method of a superordinate station includes, upon detecting an initial access of an relay station, determining an offset value between a frame number used in the superordinate station and a frame number to be used in the relay station; generating a message including RS frame offset information corresponding to the offset value; and transmitting the generated message to the relay station. Accordingly, since the base station and the relay station share the frame offset, the base station can transmit a specific broadcast message in advance to the relay station by considering the frame offset, and the relay station can transmit data, which has to be transmitted in synchronization with the base station at the same time point or at the same frame number, to a Mobile Station (MS) at an exact time point.
