A user equipment (UE) can send buffer status reports (BSRs) to a master evolved node B (MeNB) and a secondary evolved node B (SeNB). The BSRs can be formatted such that the amount of data in a radio link control (RLC) buffer at the UE and the amount of data in a packet data convergence protocol (PDCP) buffer at the UE are contained in different fields. The BSRs can also contain redundancy indicator (RI) values specifying a redundancy level between the PDCP buffer amounts included in the BSRS. The MeNB and the SeNB may then coordinate, via an X2 interface, an amount of uplink (UL) resources to allocate to the UE."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enhancement to the buffer status report for coordinated uplink grant allocation in dual connectivity in an LTE network","description":"Technology for efficiently splitting a bearer at the packet data convergence protocol (PDCP) layer for uplink (UL) data transfers in wireless networks where dual connectivity is available is disclosed","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9635655","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.
