Abstract
A method and apparatus for selecting a carrier in a wireless communication system is provided. A pico eNodeB (eNB) transmits a carrier information request message including a request of information on carriers used by a macro eNB, and receives a carrier information response message as a response of the carrier information request message, the carrier information response message including the information on carriers used by the macro eNB, the information on carriers indicating information on user equipments (UEs) corresponding to the carriers used by the macro eNB. The pico eNB selects a primary cell (PCell) of the pico eNB based on the received information on carriers used by the macro eNB.
Claims18
A method for selecting, by a pico eNodeB (eNB), a carrier in a wireless communication system, the method comprising:
- receiving reference signals from a macro eNB via a first carrier component and a second carrier component;
- transmitting a carrier information request message including a request of information on the first carrier component and the second carrier component;
- receiving a carrier information response message as a response of the carrier information request message;
- and
- selecting a primary cell (PCell) of the pico eNB based on the information on the first carrier component and the information on the second carrier component,
- wherein the carrier information request message includes information to identify each of the first carrier component and the second carrier component,
- wherein the carrier information response message includes information on the first carrier component and information on the second carrier component,
- wherein the information on the first carrier component includes a first user equipment (UE) ratio indication information element (IE) for the first carrier component and a first resource usage status IE for the first carrier component, and
- wherein the information on the second carrier component includes a second UE ratio indication IE for the second carrier component and a second resource usage status IE for the second carrier component.
A method for selecting, by a home eNodeB (HeNB), a carrier in a wireless communication system, the method comprising:
- receiving reference signals from a macro eNB via a first carrier component and a second carrier component;
- transmitting a carrier information request message including a request of information on the first carrier component and the second carrier component to a HeNB gateway (GW);
- receiving a carrier information response message as a response of the carrier information request message from the HeNB GW;
- and
- selecting a primary cell (PCell) of the HeNB based on the received information on the first carrier component and the second carrier component,
- wherein the carrier information request message includes information to identify each of the first carrier component and the second carrier component,
- wherein the carrier information response message includes information on the first carrier component and information on the second carrier component,
- wherein the information on the first carrier component includes a first user equipment (UE) ratio indication information element (IE) for the first carrier component and a first resource usage status IE for the first carrier component, and
- wherein the information on the second carrier component includes a second UE ratio indication IE for the second carrier component and a second resource usage status IE for the second carrier component.
A pico eNodeB (eNB) selecting a carrier in a wireless communication system, the pico eNodeB comprising:
- a radio frequency (RF) unit configured to transmit or receive radio signal;
- and
- a processor operatively connected to the RF unit and configured to:
- receive reference signals from a macro eNB via a first carrier component and a second carrier component;
- transmit a carrier information request message including a request of information on the first carrier component and the second carrier component;
- receive a carrier information response message as a response of the carrier information request message;
- and
- select a primary cell (PCell) of the pico eNB based on the information on the first carrier component and the information on the second carrier component,
- wherein the carrier information request message includes information to identify each of the first carrier component and the second carrier component,
- wherein the carrier information response message includes information on the first carrier component and information on the second carrier component,
- wherein the information on the first carrier component includes a first user equipment (UE) ratio indication information element (IE) for the first carrier component and a first resource usage status IEs for the first carrier component, and
- wherein the information on the second carrier component includes a second UE ratio indication IE for the second carrier component and a second resource usage status IE for the second carrier component.
