The first base station comprises a controller including at least one processor, the controller executing functions of plural layers. The plural layers include a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical (PHY) layer. The controller is configured to receive user data addressed to the user terminal from a core network, convert the user data to PDCP data unit provided with a sequence number, in the PDCP layer, and transmit the PDCP data unit to the second base station from the PDCP layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mobile communication system, base station, CoMP control apparatus and communication control method","description":"A mobile communication system includes a first base station, a second base station connected with the first base station via an X2 interface, and a user terminal configured to receive data from both t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621234","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
