Abstract

The invention provides a method and equipment for deactivating a dual cell (DC)-high-speed downlink packet access (HSDPA) auxiliary carrier. The method comprises the following steps that network-side equipment judges whether to deactivate a DC-HSDPA auxiliary carrier of user equipment (UE) or not; and when the network-side equipment judges to change the DC-HSDPA auxiliary carrier of the UE from an activation state into a deactivation state, the network-side equipment periodically transmits deactivation messages of the DC-HSDPA auxiliary carrier to the UE until the network-side equipment judges to activate the DC-HSDPA auxiliary carrier of the UE. By the method provided by the invention, the state of a DC-HSDPA physical layer kept by the UE and the network-side equipment is consistent.

Description

technical field [0001] The present invention relates to the field of communication technologies, and more specifically, to a DC-HSDPA (Dual-cell HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access), dual-carrier HSDPA) auxiliary carrier method and network side equipment and UE. Background technique [0002] In order to prolong the vitality of HSPA+ (High Speed ​​Downlink Packet Access, high-speed downlink packet access technology) technology, 3GPP (The3rd Generation Partnership Project) has continued to improve system performance and improve user throughput through various methods since the protocol Release6. rate, such as high-order modulation, multi-antenna technology, etc. The DC-HSDPA technology is newly introduced in the protocol Release8, which can improve user throughput through a larger spectrum bandwidth. DC-HSDPA technology allows a UE (User Equipment, user equipment) to establish an HSDPA connection with two adjacent frequency points ...
