[0053] In the existing multi-channel system, the scheduling method of HSUPA UE is the same as that of other existing systems, and the same channel resource can only be allocated to one UE, which makes the spectrum resource utilization rate low

Embodiment 1

[0156] Each cell and the number of channels for each cell can be determined through network planning. In a multi-channel cell, it is assumed that the cell has M channels. The isolation between each channel is very high, and the shared channel of HSUPA can be space-division multiplexed between different channels. The maximum factor for the shared channel to be space-division multiplexed is: M. That is: E-AGCH / E-HICH / E-PUCH can be used by M channels at the same time. According to the network planning, it is possible to determine the adjacent cells faced by each channel, and determine the allocation method and value of the HSUPA interference margin for each channel.

[0157] Taking the indoor coverage environment as an example, the specific space division multiplexing method in this embodiment includes the following processing:

[0158] Step 1, in the current subframe "n", determine the channel where each UE is located according to the received signal of each UE's uplink chann...

Abstract

The invention discloses a space division multiplexing method of a shared channel in a multichannel HSUPA system, comprising the following steps: presetting the timing relationship among the dispatched E-AGCH, E-PUCH and E-HICH; determining the channel on which each UE is located and the dispatching priority of each UE according to the receiving signals of each UE uplink channel; according to the priority from high to low, allocating the dispatched E-AGCH resources, E-PUCH resources and E-HICH resources for each UE, wherein any one of the E-AGCH resources, E-PUCH resources or E-HICH resources is allowed to be allocated to N numbered different channels, and each channel only can be allocated once; and performing corresponding channel data transmission on own channels of each UE according tothe allocated channel resources in terms of the timing relationship. By using the invention, frequency spectrum resource utilization rate can be improved.

Description

technical field [0001] The invention relates to channel multiplexing technology, in particular to a method for space division multiplexing of shared channels in a multi-channel HSUPA system. Background technique [0002] In HSUPA, there is one HSUPA-specific uplink transport channel E-DCH (EnhancedDCH) and five HSUPA-specific physical shared channels: E-RUCCH (E-DCH Random Access Uplink Control Channel), E-PUCH (E-DCH Physical Uplink Channel), E-UCCH (E-DCH Uplink Control Channel), E-AGCH (E-DCH Absolute Grant Channel) and E-HICH (E-DCH Hybrid Indication Channel). Among them, E-RUCCH, E-PUCH and E-UCCH are uplink physical channels. E-AGCH and E-HICH are downlink physical channels. E-PUCH is divided into scheduled E-PUCH and non-scheduled E-PUCH. E-HICH is divided into scheduled E-HICH and non-scheduled E-HICH. [0003] The E-PUCH channel has a feature different from any other uplink physical channel: when allocating an E-PUCH channel to a UE, not only the channel code re...
