Title:
OPTIMIZED SECONDARY NODE REPORTING FOR MULTI-RADIO ACCESS TECHNOLOGY DUAL CONNECTIVITY
Document Type and Number:
WIPO Patent Application WO/2020/098596
Kind Code:
A1
Abstract:
Inform a master node about the feasible of secondary node cells during resumption of dual connectivity may require a large message. Additionally, the message may need to be encrypted. A solution to overcome the size and security limitation is to report a short identifier (or index) which is only shared between the UE and the MN. Accordingly, an apparatus, e.g., a UE, may be configured to receive, from a master node, a configuration comprising a mapping of cell identities for a plurality of secondary cells for reporting SN measurements and transmitting an SN report comprising measurements for at least a subset of the plurality of secondary cells using the mapping of cell identities. The apparatus may be configured to receive, from a first master node, a configuration for MN-DC, enter an inactive state or an idle state, and resume a connected state with a second master node.
