Embodiments of the present invention provide a method and a device for synchronizing an uplink ciphering parameter in unacknowledged mode. The method for synchronizing an uplink ciphering parameter in unacknowledged mode includes: sending an indication message to a terminal when detecting that an unrecoverable error occurs in an uplink packet or that the uplink packet is invalid, where the indication message is used to instruct the terminal to initialize an uplink ciphering parameter; receiving a response message sent by the terminal; and initializing the uplink ciphering parameter according to an initial value of the ciphering parameter. The embodiments of the present invention solve a service defect, namely, a break of the communication link caused by synchronization of an uplink ciphering parameter between the terminal and the radio network controller in unacknowledged mode, and shorten the time of synchronizing the uplink ciphering parameter without interrupting the service.

Method and device for synchronizing uplink ciphering parameter in unacknowledged mode

A method, system, base station, network node, and user equipment for implementing macro diversity combining (MDC) are disclosed. In the method, a base station judges whether user equipment service data meets a condition for allocating demodulation resources. The base station allocates demodulation resources for service data meeting the condition, demodulates the service data and forwards the demodulated service data to a network node for implementing MDC.

Method, system and equipment for implementing macro diversity combining

A method and a system for implementing MDC, a base station, and a UE are provided herein. The method includes: a non-serving cell base station determines whether current services of a UE include a service whose feature meets the preset condition according to the features of the current services of the UE, and processes the service whose feature meets the preset condition as a service that needs MDC if such a service exists. Through the technical solution under the present invention, the MDC is implemented more flexibly according to the features of the current services of the UE to optimize the system performance.
