Abstract
A method and system tor 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.
