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 achieve that all the UEs belonging to one group can be controlled according to the E-RNTI which is carried in the configuration message and allocated to the group to which the UE belongs, and then can achieve the operation of activating or deactivating the process of the group, thereby reducing the utilization of E-AGCHs, improving the utilization efficiency of downlink code resources, and preventing the downlink throughput from being limited.

Embodiments of the present invention relate to the communications field, and provide a method for an uplink softer handover and a user equipment, which can support an uplink softer handover in a cell forward access channel state, so as to improve performance of a user equipment located on an edge of a cell, and meanwhile increase processing efficiency of a base station. The method is: detecting signal quality or signal strength of an intra-frequency neighboring cell; if there is an intra-frequency neighboring cell whose signal quality or signal strength meets a first threshold, reporting, through a physical control channel or by using scheduling information, related information of the intra-frequency neighboring cell that meets the first threshold to a base station to which a user equipment belongs; then, configuring, by means of predefinition or a network, a repetition period for transmitting the related information of the intra-frequency neighboring cell, and repeatedly transmitting multiple pieces of same related information of the intra-frequency neighboring cell in the repetition period, so that the base station combines the multiple pieces of the same related information of the intra-frequency neighboring cell. In the embodiments of the present invention, an uplink softer handover is supported in the cell forward access channel state.
