    摘要: A mobile communication system using an enhanced uplink dedicated transport channel transmits data at a relatively low effective data rate through non-scheduled transmission. Data transmission time intervals for user equipments (UEs) have different values in the non-scheduled transmission and therefore uplink interference is reduced. An non-scheduled transmission period N and the number of non-scheduled transmissions k are determined such that each UE performs the non-scheduled transmission. A Node B and each UE are notified of possible non-scheduled transmission time intervals based on the determined non-scheduled transmission period N and the determined number of non-scheduled transmissions k through signaling. The UE transmits the uplink data without the Node B's scheduling at the possible non-scheduled transmission time intervals.

    摘要: Method and apparatus for transmitting/receiving an uplink pilot used for channel estimation and measurement of an uplink in an FDMA system. Pilot symbols are transmitted with different frequency mapping patterns in first and second pilot symbol intervals of one time slot interval including data symbol intervals and the inconsecutive first and second pilot symbol intervals which have a shorter length than the data symbol intervals. As a result, interpolation of a frequency domain during channel estimation is not necessary, and can correctly obtain channel-estimated values of a frequency at which data is transmitted, in a fast time-varying channel environment.

    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.
