Problems solved by technology

[0006] However, in the prior art, there is no scheme for expanding HSDPA and / or HSUPA technology in a non-CELL_DCH state for a Time Division Duplex (TDD) system, and because the TDD system is a multi-frequency point system, it is different from the single Frequency point system, so the enhanced CELL_FACH technology for FDD cannot be directly applied

Embodiment 1

[0023] figure 1 It is a schematic flowchart of a method for HSPA transmission in a non-CELL_DCH state in a multi-frequency point system in Embodiment 1 of the present invention. Such as figure 1 As shown, the process includes the following steps:

[0024] Step 101, determine the first operating frequency point when the UE receives downlink data according to the instruction of the Common H-RNTI in the non-CELL_DCH state.

[0025]Wherein, the first operating frequency point of the UE may be fixedly set to a specific frequency point, such as a main frequency point. Alternatively, the corresponding relationship between the Common H-RNTI and the first operating frequency point is determined through a specific algorithm. For example, the specific algorithm can be: use the Common H-RNTI to take the modulus of the number of frequency points to obtain the first operating frequency point; or, the first operating frequency point of the UE can also be dynamically determined by the RNC,...

Abstract

The invention discloses a high-speed packet access transmission method in a non-CELL_FACH state in a multi-frequency point system, comprising the steps: a base station node (NodeB) and user equipment (UE) in the non-CELL_FACH state in the multi-frequency point system determine current working frequency point of the UE; and the transmission of high-speed downlink packet access (HSDPA) and / or high-speed uplink packet access (HSUPA) of the UE is carried out on the determined working frequency point. The technical proposal disclosed by the invention realizes the transmission of the HSPA in the non-CELL_FACH state in the multi-frequency point system, reduces the time delay for switching the states in the multi-frequency point system, and enhances the data transmission capacity in the non-CELL_FACH state.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a high-speed packet access (HSPA) transmission method in a non-community dedicated channel state in a multi-frequency point system. Background technique [0002] In the mobile communication system, in order to realize high-speed data transmission, high-speed packet access (HSPA) technology is introduced, and HSPA technology includes high-speed downlink packet access (HSDPA) technology and / or high-speed uplink packet access (HSUPA) technology. [0003] For the air interface (Uu) for communication between the network side and the user equipment (UE), the protocols related to HSDPA and / or HSUPA mainly involve the physical layer, medium access control (MAC) layer and corresponding radio resources Control (RRC) layer. Among them, the RRC layer includes two basic working modes of idle mode and connected mode, wherein the connected mode further includes cell dedicated channel state (C...
