Method and apparatus to trigger a random access procedure for carrier aggregation in a wireless communication network |
摘要 |
A method and apparatus for a base station to trigger a random access procedure for carrier aggregation in a wireless communication system are disclosed. The method includes sending a dedicated radio resource control signal to configure a user equipment with a plurality of secondary component carriers (SCCs) that include uplink SCCs and/or downlink SCCs for carrier aggregation. The method further includes sending an activation signal to the user equipment to activate a configured downlink SCC. The method also includes transmitting a physical downlink control channel order only on the downlink primary CC to trigger a random access procedure. |

1. A method for a base station to trigger a random access procedure for carrier aggregation in a wireless communication system, comprising:
sending a dedicated radio resource control (RRC) signal to configure a user equipment (UE) with a plurality of secondary component carriers (SCCs) that include uplink SCCs and/or downlink SCCs for carrier aggregation; sending an activation signal to the UE to activate a configured downlink SCC; and transmitting a physical downlink control channel (PDCCH) order only on a downlink primary component carrier (PCC) to trigger a random access procedure, wherein the downlink PCC is considered as always activated. |
