Abstract: The present invention provides a method for group scheduling grant, a user equipment and a radio network controller. The method for group scheduling grant includes: reporting, by a UE, to an RNC a capability of the UE to support an uplink enhanced dedicated channel; receiving a configuration message transmitted by the RNC, where the configuration message carries an E-RNTI; where the E-RNTI carried in the configuration message includes an E-RNTI allocated to a group to which the UE belongs; monitoring, by the UE, a first channel by using the E-RNTI carried in the configuration message, and activating or deactivating an HARQ process according to an absolute grant received by the UE in the first channel. The present invention can reduce the utilization of E-AGCHs, improve the utilization efficiency of downlink code resources, and prevent the downlink throughput from being limited.
