Abstract

Various embodiments disclosed herein provide for a compressed user equipment (UE) capability message that can indicate to a mobile network the various capabilities of the UE. In particular, the carrier aggregation and dual connectivity capabilities are compressed as disclosed herein. In traditional implementations, each carrier aggregation and dual connectivity combination and implementation that is supported is explicitly indicated in the message. As disclosed herein, rather than listing explicit combinations, the UE capability message can be compressed by instead listing boundary values of several different parameters which can be used by the network to derive the carrier aggregation and dual connectivity combinations. The UE capability message can also list the boundary values for LTE (Long Term Evolution), NR (New Radio, or 5G), and Dual Connectivity separately within the message to reduce ambiguity.
