摘要： A method and system for scheduling uplink transmissions in a single carrier frequency division multiple access (SC-FDMA) system are disclosed. A Node-B receives a scheduling request from a wireless transmit/receive unit (WTRU). The Node-B selects at least one subcarrier block having a certain bandwidth for the WTRU based on quality of service (QoS) requirement of the WTRU. If the QoS requirement is high, the Node-B selects at least one subcarrier block having a large bandwidth and if the QoS requirement is low, the Node-B selects at least one subcarrier block having a small bandwidth. The Node-B then schedules uplink transmissions in a time domain and/or a frequency domain based on a predetermined factor. The Node-B may perform frequency and/or time hopping in scheduling the uplink transmissions.

摘要： A method and apparatus for random access in an evolved universal terrestrial radio access (E-UTRA) system are disclosed. For code division multiplexing (CDM), a basic preamble is generated using a constant amplitude zero auto-correlation (CAZAC) sequence. The basic preamble is repeated for M time for generating a random access channel (RACH) preamble. For time division multiplexing/frequency division multiplexing (TDM/FDM), an extended CAZAC sequence is used to generate the basic preamble. Alternatively, a hybrid RACH access period including at least one CDM random access slot and at least one TDM/FDM random access slot may be provided. For synchronized random access, a RACH burst including a preamble part, a message part, and two cyclic prefixes may be generated and transmitted

摘要： Methods and systems for sending and receiving an enhanced downlink control channel are disclosed. The method may include receiving control channel information via an enhanced control channel. The method may also include using the control channel information to receive a shared channel. The method may include detecting the presence of the enhanced control channel in a given subframe. The enhanced control channel may be transmitted over multiple antenna ports. For example, code divisional multiplexing and de-multiplexing and the use of common and UE-specific reference signals may be utilized. New control channel elements may be defined, and enhanced control channel state information (CSI) feedback may be utilized. The presence or absence of legacy control channels may affect the demodulation and or decoding methods. The method may be implemented at a WTRU.

摘要： A method and apparatus for selecting a TFC in a wireless transmit/receive unit (WTRU) is disclosed. The WTRU estimates a transmit power for each of a plurality of available transport format combinations (TFCs). A TFC is selected for an uplink dedicated channel and a TFC is selected for an enhanced uplink (EU) channel. The TFC for the dedicated channel is selected first and independently of the TFC selection of the EU channel. The TFC for the EU channel is selected within a remaining WTRU transmit power after the TFC selection for the dedicated channel.

摘要： A wireless communication method and system for controlling the current data bit rate of a radio link (RL) to maintain the quality of the RL. The system includes a core network (CN), a radio network controller (RNC) and at least one wireless transmit/receive unit (WTRU). The RL is established between the RNC and the WTRU. The RNC establishes a guaranteed data bit rate, a maximum data bit rate and a current data bit rate associated with the RL. When the RNC senses an event which indicates that the quality of the RL has substantially deteriorated, the RNC reduces the value of the current data bit rate. Then, in a recovery process, if a similar event does not occur during an established waiting period, the RNC restores the current data bit rate back to the maximum data bit rate.
