Abstract
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.
Claims16
A method for implementing Macro Diversity Combining (MDC)-, the method comprising:
- determining, by a non-serving cell base station, whether current services of a UE include a service with a feature that meets a preset condition according to features of the current services of the UE;
- processing, by the non-serving cell base station, the service with the feature that meets the preset condition as a service requiring MDC if the result of the determining is that current services of the UE include a service with a feature that meets the preset condition;
- and
- receiving and demodulating, by the non-serving cell base station, only the data on the uplink control channel, and performing uplink power control for the UE, if the result of the determining is that current services of the UE do not include a service with a feature that meets the preset condition.
A base station for implementing Macro Diversity Combining (MDC), the base station comprising:
- a determining unit, adapted to determine whether current services of a UE include a service with a feature that meets a preset condition according to features of current services of the UE;
- a processing unit, adapted to process the service with the feature that meets the preset condition as a service requiring MDC if the determining unit determines that current services of the UE include a service with a feature that meets the preset condition;
- and
- a power control unit, adapted to receive and demodulate only the data on the uplink control channel, and to implement uplink power control for the UE, if the determining unit determines that current services of the UE do not include a service with a feature that meets the preset condition;
- wherein the base station is a non-serving base station and the network node that executes MDC is a serving cell base station or a Radio Network Controller (RNC).
A system for implementing Macro Diversity Combining (MDC), the system comprising:
- a non-serving cell base station for implementing MDC, and
- a network node that executes MDC,
- wherein the non-serving cell base station comprises:
- a determining unit, adapted to determine whether current services of a UE include a service with a feature that meets a preset condition according to features of the current services of the UE;
- a processing unit, adapted to process the service with a feature that meets the preset condition as a service requiring MDC if the determining unit determines that current services of the UE include a service with a feature that meets the preset condition;
- and
- a power control unit, adapted to receive and demodulate only data on the uplink control channel, and to implement uplink power control for the UE, if the determining unit determines that current services of the UE do not include a service with a feature that meets the preset condition;
- wherein the network node that executes MDC is a serving cell base station or a Radio Network Controller and
- wherein the network node that executes MDC comprises:
- a receiving unit, adapted to receive services from the non-serving cell base station, wherein the services are determined as requiring MDC according to service features;
- and
- an MDC executing unit, adapted to execute MDC operations for the services received by the receiving unit.
