Embodiment 1

[0077] like figure 2 As shown in the figure, it is a dual-cell mode with the same frequency point across base stations. UE performs downlink reception from a single downlink frequency point F1 of two different base stations. RNC configures primary base station 1 and secondary base station 2 through the Iub interface message flow, and UE is under the jurisdiction of primary base station 1. At the same time, the UE also transmits uplink data in the secondary serving cell (that is, sector 2) under the jurisdiction of the secondary base station 2. The primary base station 1 maintains the UE's X, Two downlink receiving links Y and two uplink sending links M and N, while the secondary base station 2 only maintains one downlink receiving link Y and one uplink sending link N of the UE. Then the method for implementing the HS-SCCH order by the UE includes:

Embodiment 2

[0081] like figure 2 As shown in the figure, it is a dual-cell mode with the same frequency point across base stations. UE performs downlink reception from a single downlink frequency point F1 of two different base stations. RNC configures primary base station 1 and secondary base station 2 through the Iub interface message flow, and UE is under the jurisdiction of primary base station 1. In the primary serving cell (that is, sector 1), the uplink data is sent on the uplink frequency point paired with the downlink frequency point F1, which corresponds to the uplink transmission link M; at the same time, according to the configuration on the network side, the UE can also transmit data in the secondary base station 2 In the secondary serving cell under the jurisdiction (that is, sector 2), the uplink data transmission is performed on the uplink frequency point paired with the downlink frequency point F1, corresponding to the uplink transmission link M; the primary base station 1...

Embodiment 3

[0085] like Figure 4 As shown, it is a dual-cell mode across base stations with different frequencies. RNC configures primary base station 1 and secondary base station 2 through the Iub interface message flow. Sector 1 of primary base station 1 sends data downlink at the downlink frequency point F2, corresponding to the downlink receiving link X , the sector 2 of the secondary base station 2 sends downlink data at the downlink frequency point F1, corresponding to the downlink receiving link Y; at the same time, the UE has the dual-carrier uplink transmission capability, and the uplink frequency point F4 (uplink primary carrier) paired with the downlink frequency point F2 ), corresponding to the uplink transmission link M, and at the same time, according to the configuration of the network side, the UE may also perform uplink transmission on the uplink frequency point F3 (uplink secondary carrier) paired with F1, corresponding to the uplink transmission link N. Primary base stat...

Abstract

The invention discloses a method for implementing a high-speed shared control channel (HS-SCCH) command by a terminal. The method comprises: a master NodeB configures and maintains corresponding downlink receiving links and uplink transmitting links in all service cells corresponding to user equipment (UE) under an inter-NodeB multipoint transmission mode; a slave NodeB configures and maintains corresponding downlink receiving links and uplink transmitting links in slave service cells managed by the slave NodeB; the UE implements an HS-SCCH command sent by a master service cell managed by the master NodeB so as to control the corresponding downlink receiving links or uplink transmitting links in all the service cells; and the UE implements an HS-SCCH command sent by the slave service cells managed by the slave NodeB so as to control the corresponding downlink receiving links and uplink transmitting links in the slave service cells managed by the slave NodeB. The invention also discloses a terminal, and a system for implementing the HS-SCCH command by the terminal. According to the invention, the problem that the UE cannot implement the HS-SCCH command perfectly because the intra-NodeB HS-SCCH commands are uncoordinated in an inter-NodeB multipoint transmission scene can be solved.

Description

technical field [0001] The invention relates to the technical field of digital mobile communication, in particular to a method, a system and a terminal for implementing HS-SCCH orders by a terminal. Background technique [0002] In the Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) network, the Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestrial Radio Access Network) includes a radio network controller (RNC, Radio Network Controller) and a base station (NodeB) Two basic network elements. [0003] With the development of WCDMA network, High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access), High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access), Dual Carrier High Speed ​​Downlink Packet Access (DC-HSDPA) , DualCarrier-High speed downlink packet access), dual-band dual-carrier high-speed downlink packet access (DB-DC-HSDPA, Dual band-Dualcarrier-high speed downlink pac...
