Abstract
A method, base station, terminal and communication system for updating component carriers 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 carrier which the terminal would use is updated more effectively.
Claims27
A base station in a carrier aggregation communication network, comprising:
- processing circuitry
- configured to:
- update an old secondary component carrier for a terminal;
- and transmit, to the terminal, radio resource control reconfiguration information specifying radio resource configuration information of an updated secondary component carrier for configuring the updated secondary component carrier,
- wherein the updated secondary component carrier is configured independently of reconfiguring a Medium Access Control (MAC) layer and independently of updating a security key.
A method for updating a secondary component carrier for a terminal in a carrier aggregation communication network, comprising:
- transmitting, by processing circuitry, from a base station that hosts an updated secondary component carrier, radio resource control reconfiguration information specifiying radio resource configuration information of the updated secondary component carrier to the terminal for configuring the updated secondary component carrier,
- wherein the updated secondary component carrier is configured independently of reconfiguring a Medium Access Control (MAC) layer and independently of updating a security key.
A terminal for a carrier aggregation communication network, comprising:
- processing circuitry
- configured to receive radio resource control reconfiguration information from a base station;
- and
- configure a new secondary component carrier with radio resource configuration information specified by the radio resource control reconfiguration information, the configuring being performed independently of reconfiguring a Medium Access Control (MAC) layer and independently of updating a security key.
