CONTROL OF UPLINK TRANSMISSION

摘要

A dedicated grant may be shared by a group of WTRUs for performing uplink communications. A WTRU in a group may use the dedicated grant when it receives a group identifier and/or a WTRU identifier that are associated with the WTRU. The uplink communications from each WTRU transmitting in a group may be time-aligned. WTRUs may be allowed to transmit on the uplink channel using the dedicated grant for a designated time period. The WTRU may perform uplink control using MCS configurations controlled by the network. The WTRU may receive an indication of the MCS parameters or an MCS adjustment that may be applied to uplink communications. Uplink communications may be performed using an active non-scheduled transmission mode of operation or an inactive non-scheduled transmission mode of operation. Uplink load balancing may be performed by the network during dynamic frequency handover to manage the data packets being transmitted.
