Abstract
A method for reporting UE capability in a wireless communication system which includes receiving capability indexes related to the UE capability from a network; and transmitting at least one of the capability indexes and difference configuration of the UE capability compared to the at least one of the capability indexes to the network.
Claims5
A method for reporting, by a user equipment (UE), UE capability in a wireless communication system, the method comprising:
- establishing a radio resource control (RRC) connection with a network;
- receiving, from the network, a UE capability enquiry message;
- checking whether system information related to UE capability is valid or not;
- receiving, from the network, the system information related to UE capability based on that the system information related to the UE capability is not valid,
- system information related to the UE capability includes a list of capability indexes related to the UE capability and a list of capability parameter sets related to the UE capability,
- wherein the capability parameter sets include UE model, RF parameter, physical parameter, and MAC parameter, and
- wherein each of the capability indexes is associated with each of the capability parameter sets;
- constructing a UE capability reporting message;
- and
- transmitting the UE capability reporting message in response to the UE capability enquiry message;
- wherein the UE capability reporting message includes only a capability index associated with a capability parameter set fully matched with a current capability parameter set of the UE based on that the current capability parameter set of the UE is included in the list of capability parameter sets,
- wherein the UE capability reporting message includes a capability index with a capability parameter set partially matched with a current capability parameter set of the UE and a difference configuration between the current capability parameter set of the UE and the capability parameter set based on that a part of the current capability parameter set of the UE is included in the list of capability parameter sets, and
- wherein the UE capability reporting message includes a current capability parameter set of the UE based on that the current capability parameter set of the UE is not included in the list of capability parameter sets.

A user equipment (UE) in a wireless communication system, the UE comprising:
- a transceiver for transmitting and receiving a radio signal;
- and
- a processor coupled to the transceiver,
- the processor configured to:
- establish a radio resource control (RRC) connection with a network;
- control the transceiver to receive, from the network, a UE capability enquiry message;
- check whether system information related to UE capability is valid or not;
- control the transceiver to receive, from the network, the system information based on that the system information related to the UE capability is not valid,
- wherein the system information related to the UE capability includes a list of capability indexes related to the UE capability and list of capability parameter sets related to the UE capability, wherein the capability parameter sets include UE model, RF parameter, physical parameter, and MAC parameter, and wherein each of the capability indexes is associated with each of the capability parameter sets;
- construct a UE capability reporting message;
- and
- control the transceiver to transmit the UE capability reporting message in response to the UE capability enquiry message;
- wherein the UE capability reporting message includes only a capability index associated with a capability parameter set fully matched with a current capability parameter set of the UE based on that the current capability parameter set of the UE is included in the list of capability parameter sets,
- wherein the UE capability reporting message includes a capability index with a capability parameter set partially matched with a current capability parameter set of the UE and a difference configuration between the current capability parameter set of the UE and the capability parameter set based on that a part of the current capability parameter set of the UE is included in the list of capability parameter sets, and
- wherein the UE capability reporting message includes a current capability parameter set of the UE based on that the current capability parameter set of the UE is not included in the list of capability parameter sets.
