Problems solved by technology

However, since the UE can only support one HSUPA carrier, the improvement of the peak uplink rate and uplink throughput of the single-carrier HSUPA UE is very limited.

Embodiment Construction

[0072] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0073] The basic idea of ​​the present invention is: when allocating E-PUCH resources for a UE supporting multiple HSUPA carriers, it allows simultaneous scheduling of multiple HSUPA carriers of the UE through one E-AGCH. That is, by sending the scheduled E-AGCH once, the E-PUCH resources on multiple HSUPA carriers supported by the UE in one subframe are allocated to the UE.

[0074] Specifically, in the multi-carrier HSUPA implementation method of the present invention, each cell on the NODEB side has a scheduler, and the scheduler implements joint scheduling of all HSUPA UEs on all HSUPA carriers in the cell. In each subframe, the scheduler of the cell performs HSUPA scheduling once, selects the scheduled UE from all HSUPA UEs in the cell through scheduling, and d...

Abstract

The invention discloses a method for realizing multi-carrier HSUPA. The method comprises the following steps of: setting an independent HSUPA dispatcher for each cell by using a NodeB; performing combined dispatching on all HSUPA UE borne on all HSUPA carriers in the cell in each sub-frame by using the HSUPA dispatcher of the each cell; and when distributing E-PUCH resources for the HSUPA UE supporting a plurality of HSUPA carriers, allowing an E-AGCH to dispatch the E-PUCH on a plurality of carriers at the same time. Therefore, the E-PUCH resources on the plurality of the carriers can be used for transmitting data for the HSUPA UE at the same time, which greatly improves uplink peak rate and uplink throughput relative to a single carrier. Furthermore, the method for dispatching the plurality of the carriers of UE by using one E-AGCH at the same time can effectively save E-AGCH resources.

Description

technical field [0001] The present invention relates to high-speed uplink packet access (HSUPA) technology, in particular to a method for realizing multi-carrier HSUPA. Background technique [0002] At present, the 3GPP standard has provided the realization method of the single carrier HSUPA. In the single-carrier HSUPA implementation method, the NODEB side needs to implement the following process: [0003] Each HSUPA carrier in each cell of the NODEB has an HSUPA scheduler (hereinafter referred to as the scheduler), and the scheduler realizes the scheduling of the HSUPA UE on the carrier. On the NODEB side, several E-AGCHs and several scheduled E-HICHs can be configured on each HSUPA carrier. Each HSUPA carrier has an independent scheduled E-PUCH resource pool. On the NODEB side, the scheduler of each HSUPA carrier will allocate an E-AGCH set and a scheduled E-HICH set for each HSUPA UE on the carrier: the scheduler selects a part of E-AGCH from the E-AGCH of the carrier...
