Abstract: Embodiments of the present disclosure describe methods and apparatuses for UE capability reporting in mobile communication systems. UE capability reporting in LTE with high number of CCs (32) creates a great signalling overhead. An enhanced network enquiry message (UECapabilityEnquiry) is proposed which includes indications (e.g. maximum aggregated CC number or bandwidth class, MIMO/CSI-process capabilities) that indicate to a UE that the UE is to exclude, from its capability report (UECapabilityInformation), information related to functions that the network either does not support or is not interested in. The enhanced network enquiry message may include indications of a max. number of DL/UL CCs for which the UE is requested to provide supported CA band combinations and non-CA bands. The UE selects a subset of CA capabilities based on these indicator and generates a UE capability response (UECapabilityInformation) including information related to the selected subset of CA capabilities.
