Method, system and apparatus for notifying a UE of monitored component carriers

摘要

The present invention provides a method for notifying a UE of monitored component carriers. The method comprises the following steps: an evolved Node B (eNB) sends an monitoring changing instruction and Component Carriers (CC) corresponding to the instruction to a UE with a Media Access Control (MAC) layer control command; according to the monitoring changing instruction and the corresponding CC, the UE activates or deactivates monitoring of the corresponding CC. The present invention allows the MAC PDU for instructing the UE to increase, decrease or change the monitored CC. Therefore, the configuration can be achieved in a simple and flexible manner and has higher reliability.

1. A method for notifying a UE of monitored component carriers, comprising the following steps:
an eNB sending a monitoring changing instruction and Component Carrier corresponding to the instruction to the UE with a MAC layer control command; the UE activating or deactivating monitoring of the corresponding CC according to the monitoring changing instruction and the CC corresponding to the instructions; wherein the step of the eNB sending the monitoring changing instruction and the CC corresponding to the instruction to the UE with the MAC layer control command comprises the eNB adding one MAC CE, which bears the instruction and the corresponding CC, into the MAC PDU, and adding an identifier indicating existence of the MAC CE in a MAC head of the MAC PDU; and wherein the step of adding an identifier indicating existence of the MAC CE in a MAC head of the MAC PDU comprises: (1) adding a MAC subheader corresponding to the MAC CE into the MAC head, and LCID in the MAC subheader is an identifier for indicating the existence of the MAC CE; or (2) the first MAC subheader of the MAC head bearing the identifier, and the MAC CE locating an initial position of MAC PDU payload.
