摘要： A transmitter and receiver for fast frequency hopping based on a cyclic frequency hopping pattern in an orthogonal frequency division multiplexing system. The transmitter outputs a transmission signal vector having a plurality of samples. In the receiver, a first Fast Fourier Transform (FFT) processor transforms a first received signal vector into a second received signal vector of a frequency domain by using FFT. An equalizer multiplies the received signal vector by an inverse matrix of a channel matrix representing characteristics of a channel from the transmitter to the receiver. A modified IFFT processor transforms output of the equalizer by using IFFT, and multiplies IFFT outputs of a last stage of the modified IFFT processor by predetermined gains associated with the cyclic frequency hopping pattern of the transmitter. A second FFT processor transforms output of the modified IFFT processor by using FFT to output a recovered received signal vector.

摘要： Methods and apparatuses are described for a Node B to transmit Reference Signals (RS) from multiple antennas to enable User Equipments (UEs) to perform demodulation of received information signals and to estimate Channel Quality Indication (CQI) metrics. To minimize overhead and enable backward compatible operation with legacy systems, RS from a first set of Node B antennas are transmitted in every transmission time interval and substantially over the whole operating BandWidth (BW). RS from a second set of Node B antennas serving for CQI estimation are periodically transmitted, substantially over the whole operating BW, with transmission period informed to UEs through broadcast signaling by the Node B and starting transmission sub-frame determined from the identity of the cell served by the Node B. RS from the second set of antennas, and new RS from the first set of antennas, serving for demodulation of information signals have substantially the same BW as the information signals which can be smaller than the operating BW.

摘要： A method and apparatus for transmitting/receiving a Random Access Channel (RACH) signal in a communication system. A User Equipment (UE) selects one of Contention Resolution (CR) channels allocated for collision detection, and transmits the selected CR channel and a connection request message to an Evolved Node B (E-NB), and receives a response signal from the E-NB. The UE transmits the RACH signal, if a collision indicator is included in the response signal. The E-NB receives from each of UEs a connection request message and a CR channel, decodes the connection request message, and detects a collision between the UEs using the CR channel. The E-NB generates a response signal to the connection request message according to the decoding result, generates a collision indicator according to the collision detection result, and transmits to the UEs at least one of the generated response signal, the generated collision indicator, and a unique ID of a corresponding UE.
