Abstract
A method, base station, terminal and communication system for updating component carders are provided. Wherein, status information of the terminal, base station and/or component carrier is acquired; whether the status information accords with the predetermined condition is determined; an old component carrier is replaced by a new component carrier, or a new component carrier is added in the even that the predetermined condition is met. With the embodiments of the present invention, the component carder which the terminal would use is updated more effectively.
Claims20
An electronic device in a user equipment in a carrier aggregation communication network, comprising:
- circuitry configured to update a primary component carrier (PCC) that support communications with a base station in a carrier aggregation communication scheme, including
- a transceiver configured to receive from the base station Radio Resource Control (RRC) reconfiguration information that includes a updated PCC information and mobility control information, wherein
- the updated PCC is selected based on a distribution mode identifying a relationship between coverage ranges of component carriers in the carrier aggregation communication network,
- the circuitry is configured to reconfigure a Media Access Control (MAC) layer, a Packet Data Convergence Protocol (PDCP) layer and a Radio Link Control (RLC) layer, update a security key with the mobility control information in the RRC reconfiguration information, and reconfigure the primary component carrier as the updated PCC with the RRC reconfiguration information.
A method for updating component carriers in a carrier aggregation communication network, comprising:
- updating a primary component carrier (PCC) that support communications with a base station in a carrier aggregation communication scheme, including
- receiving from the base station Radio Resource Control (RRC) reconfiguration information that includes a updated PCC information and mobility control information, wherein
- the updated PCC is selected based on a distribution mode identifying a relationship between coverage ranges of component carriers in the carrier aggregation communication network,
- the method further comprises reconfiguring a Media Access Control (MAC) layer, a Packet Data Convergence Protocol (PDCP) layer and a Radio Link Control (RLC) layer, updating a security key with the mobility control information in the RRC reconfiguration information, and reconfiguring the primary component carrier as the updated PCC with the RRC reconfiguration information.
A non-transitory computer storage medium that contains computer readable instructions that when executed by a processor performs a method for updating component carriers in a carrier aggregation communication network, the method comprising:
- updating a primary component carrier (PCC) that support communications with a base station in a carrier aggregation communication scheme, including
- receiving from the base station Radio Resource Control (RRC) reconfiguration information that includes a updated PCC information and mobility control information, wherein
- the updated PCC is selected based on a distribution mode identifying a relationship between coverage ranges of component carriers in the carrier aggregation communication network,
- the method further comprises reconfiguring a Media Access Control (MAC) layer, a Packet Data Convergence Protocol (PDCP) layer and a Radio Link Control (RLC) layer, updating a security key with the mobility control information in the RRC reconfiguration information, and reconfiguring the primary component carrier as the updated PCC with the RRC reconfiguration information.
