Abstract
This disclosure provides mechanisms for User Equipment, UE, capability signaling and coordination for Long Term Evolution (LTE) and New Radio (NR) tight-interworking without increasing the complexity of LTE capability reporting. This disclosure proposes a capability signaling and coordination framework in order to coordinate at least band combinations and Layer 2 buffer capabilities across the master and the secondary nodes which are of different Radio Access Technologies (RATs), such as LTE and NR.

1-41. (canceled)
A method performed by a user equipment (UE) to signal capabilities for a first radio access technology (RAT) and a second RAT different from the first RAT, the method comprising:
- transmitting a first message to a first network node, the first network node implementing the first RAT, wherein the first message comprises joint UE capability information relevant to both the first RAT and the second RAT, wherein
- the first RAT is a Long Term Evolution (LTE) RAT and the second RAT is a New Radio (NR) RAT.
A method performed by a first network node of a first Radio Access Technology (RAT), the method comprising:
- receiving from a UE a first message comprising joint UE capability information relevant to both the first RAT and a second RAT different than the first RAT, wherein
- the first RAT is a Long Term Evolution (LTE) RAT and the second RAT is a New Radio (NR) RAT.
A method performed by a second network node of a second Radio Access Technology (RAT), the method comprising:
- receiving from a first network node of a first RAT a message comprising UE joint UE capability information relevant to both the first RAT and the second RAT different than the first RAT;
- reading and decoding the joint UE capability information included in the message;
- using the joint UE capability information to select a NR SCG configuration;
- and
- transmitting to the first network node information pertaining to the selected NR SCG configuration, wherein
- the first RAT is a Long Term Evolution (LTE) RAT and the second RAT is a New Radio (NR) RAT.
