Problems solved by technology

[0006] Since the Enhanced CELL_FACH technology and various HS-SCCH orders share HSDPA code channel resources (including HS-PDSCH and HS-SCCH) and power resources with UEs that need to send data in the CELL_DCH state, if the resources of the three cannot be well allocation, the transmission performance of UEs in CELL_FACH state and HS-SCCH order cannot be guaranteed, and at the same time, the utilization rate of HS-PDSCH code channel resources will be reduced, thereby reducing the throughput rate of UEs in CELL_DCH state

Embodiment Construction

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] The data rate of the UE (user or terminal) in the enhanced CELL_FACH state is relatively low, and the HS-PDSCH code channel resources and power resources consumed are relatively small, so the policy of priority guarantee is adopted; while the UE data rate in the CELL_DCH state is usually relatively high, and a single The HS-PDSCH code channel resources and power resources consumed by the UE are relatively large. Therefore, when UEs in CELL_FACH state and UEs in CELL_DCH state share HSDPA resources based on code division multiplexing, in order to ...

Abstract

The invention provides a downlink resource distribution method. The method comprises the following steps that: 1, a base station reserves a partial high-speed shared control channel (HS-SCCH) code channel; 2, the base station dispatches user equipment (UE) for sending HS-SCCH order by using the reserved HS-SCCH code channel; 3, the base station dispatches the UE in a cell forward access channel (CELL-FACH) state by using the residual reserved HS-SCCH code channel; and 4, finally, the base station dispatches the UE in a cell dedicated channel (CELL-DCH) state by using the residual reserved HS-SCCH code channel. The invention also provides a downlink resource distribution device, the base station and a system thereof. The invention can improve the utilization rate of high-speed physical downlink shared channel (HS-PDSCH) code channel resources at the same time of ensuring the enhancement of the sending performance of the UE in the CELL-FACH state and the HS-SCCH order so as to improve the throughput of the UE in the CELL-DCH state.

Description

technical field [0001] The present invention relates to High Speed ​​Packet Access Evolution (HSPA+) mobile communication technology, in particular to a downlink resource allocation method, device, base station and its introduction when a base station (NodeB) in HSPA+ supports downlink enhanced CELL_FACH and HS-SCCH order technologies system. Background technique [0002] The 3rd Generation Partnership Project (3GPP) introduced technologies such as enhanced CELL_FACH, CPC (Continuous Packet Connectivity, continuous packet connection), E-SCC and DC-HSDPA in the downlink in the HSPA+ evolution, and introduced DC-HSUPA technology in the uplink Wait. [0003] After the introduction of F-DPCH in the 3GPP R6 version, the wireless signaling bearer SRB will be sent through the HS-DSCH, thereby greatly reducing the signaling transmission delay. The enhanced CELL_FACH technology is introduced in R7, so that the UE in the CELL_FACH state can use the HS-DSCH transmission channel, redu...
