摘要:
Wireless user equipment (UE) operating in a wireless communication system may operate in a state, for example, the CELL_FACH state in UMTS, that does not allow for soft handoff from one cell to another. This inability to engage in soft handover may lead to intercell interference at a non-serving cell when the UE transmits on its uplink in close proximity to the non-serving cell. Therefore, provided in the present disclosure is method of wireless communication, which includes receiving a neighbor cell identification set indicating one or more neighbor cells, receiving a relative grant channel resource index corresponding to a relative grant channel shared by at least one of the one or more neighbor cells, detecting intercell interference associated with a user equipment (UE) in the one or more neighbor cells, and transmitting a non-serving relative grant message to the UE on the relative grant channel.
