Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple base stations are deployed with higher density to ensure good network coverage, then network coverage and service quality are improved, but device complexity and routing complexity increase
Solution Approach 1:
The master base station acts as an intermediary node between the data gateway and slave base stations. It receives data packets from the data gateway, performs complete processing, and then routes processed data to slave base stations which perform only transmission. This intermediary role simplifies the overall routing complexity by centralizing processing decisions at the master base station while maintaining the benefits of multiple deployed base stations for network coverage.
2Reliability
If multiple base stations form a cloud cell to serve mobile stations, then service quality and equal grade of service are improved, but data packet processing complexity increases
Solution Approach 1:
The data packet processing function is segmented between master base stations and slave base stations. Master base stations perform complete processing including MAC and PHY processing, while slave base stations perform only transmission functions. This segmentation reduces the processing complexity at individual slave base stations while maintaining the collaborative cloud cell structure that ensures high service quality and equal grade of service across multiple base stations.
3Adaptability or versatility
If a base station acts as master for one mobile station and slave for another in overlapping cloud cells, then network flexibility and service coverage are improved, but routing decision complexity increases
Solution Approach 1:
The master-slave relationship between base stations is dynamic and context-dependent rather than fixed. A base station can act as a master base station for one mobile station while acting as a slave base station for another mobile station in overlapping cloud cells. This dynamic role assignment allows the network to adapt flexibly to different service requirements and mobile station locations, managing routing complexity through contextual role switching rather than rigid hierarchical structures.

AI summary
The present disclosure provides a method and apparatus for communicating data packets in a cloud cell. In one embodiment, a network node from which data packets are received is identified by the BS. If the data packets are received from a data gateway, a network node to which the data packets to be sent is identified. If the data packets are to be sent to a slave BS, partial processing is performed on the data packets by the master BS. Furthermore, partially processed data packets are transmitted to the slave BS so that the slave BS performs complete processing on the partially processed data packets and transmits the completely processed data packets to the MS. If the data packets are to be sent to the MS, then complete processing of the data packets is performed by the BS and transmitted to the MS.
