    摘要: A method for providing multiple-user multiple-input and multiple-output in a high-speed packet access system is described. A channel quality indicator is received from a dual-stream-capable wireless communication device requesting a single-stream transmission at a first data rate. The first data rate is adjusted by an adaptive outer loop margin to obtain a second data rate. A data stream is transmitted to the wireless communication device using the second data rate. A positive-acknowledgement/negative-acknowledgement (ACK/NACK) is received from the wireless communication device. The adaptive outer loop margin is adjusted according to the received ACK/NACK.

    摘要: A method for providing multiple-user multiple-input and multiple-output in a high-speed packet access system is described. Channel quality indicators are received from a plurality of dual stream capable wireless communication devices. A preferred beam and a secondary beam are determined for each wireless communication device using the channel quality indicators. Wireless communication devices with preferred beams orthogonal to each other are paired. A wireless communication device pair is selected. Data streams for the selected wireless communication device pair are scheduled in the same transmission time interval using an orthogonal variable spreading factor code.

    摘要: A system and method provide single frequency, dual cell high-speed downlink packet access to a UMTS telecommunications system. A first downlink channel is provided from a first sector, and a second downlink channel is provided from a second sector, wherein the first downlink channel and the second downlink channel are in substantially the same carrier frequency. Feedback information such as a CQI and/or a PCI is provided on an uplink channel to facilitate adaptation of the respective downlink channels. Here, the uplink carrier may be in the same or a different carrier frequency than that of the downlink channels.

    摘要: Techniques for signaling power information to facilitate channel quality indicator (CQI) reporting are described. A Node B may send power information that may be used by a UE to determine a power per channelization code, POVSF. In one design, the power information includes a power offset between the power of a data channel, PHSPDSCH, and the power of a pilot channel. The Node B may determine PHSPDSCH based on the power available for the data channel, the number of available channelization codes, and a designated number of channelization codes. The UE may determine POVSF based on the power information from the Node B and the designated number of channelization codes. The UE may estimate at least one SINR of at least one transport block based on POVSF, determine CQI information for the transport block(s) based on the SINR, and send the CQI information to the Node B.
