Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that according to this method, there are at least the following problems: if the carrier configuration carries the connection relationship between the carriers at the same time, because not all of them are activated during activation, there will be some carriers When no carrier is connected
In addition, if RRC signaling is used to configure the connection relationship between carriers, since MAC CE is used for carrier activation, there will be a mismatch between connection relationship configuration and activation time
These situations will affect the normal progress of UE communication

Embodiment Construction

[0019] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations. Wherein, the DL CC represents a downlink component carrier (Downlink Component Carrier), and the UL CC represents an uplink component carrier (Uplink Component Carrier).

[0020] In the LTE-A system, for a UE, such as figure 2 As shown, there may be the following three possible carrier configuration situations:

[0021] 1.1-1 connection (1 to 1 connection), such as figure 2 As shown in (A), DL CC1 and DL CC2 are downlink carriers, UL CC1 and UL CC2 are uplink carriers, and the connection relationship is: DL CC1 and UL CC1 are connected, DL CC2 and UL CC2 are connected;

[0022] 2. N-1 connection (many-to-1 connection), such as figure 2 As shown in (B), DL CC1 and DL CC2 are downlink carriers, and UL CC1 is a...

Abstract

The embodiment of the invention relates to the technical field of communication, and discloses a carrier management method and a base station. The method comprises the following steps of: when a first configured carrier is to be activated or deactivated for user equipment (UE), determining connection relationships with the first carrier according to the conditions of other activated or to-be-activated carriers of the UE; and when the first carrier is activated or deactivated, informing the UE of the connection relationship to indicate the UE to update the connection relationships, stored by the UE, among carriers according to the connection relationships. The embodiment of the invention can realize effective management over the connection relationships among the uplink and downlink carriers of the UE in a long-term evolution advance (LTE-A) system, and ensure normal communication.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a carrier management method and a base station. Background technique [0002] Currently, in order to meet the requirements of IMT-A (International Mobile Telecommunications Advance, the next generation of international mobile communications) and support higher peak data rates, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) LTE-A (Long-Term EvolutionAdvance, the evolution version of the long-term evolution) system uses the carrier aggregation technology as its method of expanding the system bandwidth. The main idea of ​​carrier aggregation technology is to aggregate multiple carriers into a carrier higher than 20MHz to support high-speed data rates. [0003] In the LTE-A system, although a UE (User Equipment, user equipment) still only receives service in one cell, it has multiple uplink / downlink carriers to meet higher user data rate...
