Problems solved by technology

In this way, the peak uplink rate of the UE can only reach 512kbps that can be supported by 1 time slot (2:4 configuration) or 1024kbps that can be supported by 2 time slots, and cannot reach 1.5 time slots (2:4 configuration). ) can support 512×1.5kbps or 2.5 time slots (3:3 configuration) can support 1024×1.5kbps

Embodiment 1

[0086] Normally, the E-PUCH resource pool configured by the RNC to the NODEB occupies several complete time slots and several incomplete time slots. Therefore, in any subframe, the E-PUCH resource pool on an HSUPA carrier can be divided into two rectangular E-PUCH resource pools, and these two resource pools can be divided according to needs. Preferably, the first one consists of several complete time slots constituted, and the second consists of one or more non-complete slots. In this embodiment, two rectangular resource pools A and B obtained by dividing according to needs are described. Preferably, the first rectangular E-PUCH resource pool A consists of several complete time slots, and the second rectangular resource pool B consists of partial resources of one time slot.

[0087] For a UE that supports non-rectangular E-PUCH resource allocation, when it is necessary to allocate non-rectangular E-PUCH resources to the UE, the non-rectangular E-PUCH resource allocated to th...

Embodiment 2

[0165] In this embodiment, for a UE that supports non-rectangular E-PUCH resource allocation, when the NodeB needs to allocate non-rectangular E-PUCH resources for the UE, the allocated non-rectangular E-PUCH resources are divided into multiple rectangular resources, from Multiple E-AGCHs are selected from the E-AGCH set of the UE, and the number of selected E-AGCHs is equal to the number of divided rectangular resources. Each E-AGCH is used to notify the UE of relevant information of a rectangular resource. When selecting the E-AGCH, it can be selected according to information such as serial numbers, and preferably, when scheduling the same UE continuously, try to select the E-AGCH previously allocated to the UE.

[0166] Wherein, when each E-AGCH carries information related to a rectangular resource, the E-AGCH format still adopts the existing format, and the values ​​of other fields except the CRRI field and the TRRI field are the same as the existing determination method. ...

Abstract

The invention provides a method for distributing non-rectangular enhanced physical uplink channel (E-PUCH) resources in high speed uplink packet access (HSUPA). The method has the following beneficial effects: when the nodeB distributes the E-PUCH resources to user equipment (UE), the nodeB distributes the non-rectangular E-PUCH resources to the UE which supports non-rectangular E-PUCH resource distribution, divides the distributed non-rectangular E-PUCH resources into a plurality of rectangular resources and informs the UE of the time slots and node information of the plurality of rectangular resources via an enhanced absolute grant channel (E-AGCH); therefore the aims of distributing the non-rectangular E-PUCH resources to the UE and informing the UE of the distributed resources can be achieved, thus ensuring the UE to utilize the non-rectangular E-PUCH resources to transmit data and improving the uplink peak rate of the UE.

Description

technical field [0001] The invention relates to resource allocation technology in high-speed uplink packet access (HSUPA), in particular to a non-rectangular enhanced dedicated channel physical uplink channel (E-PUCH) resource allocation method in HSUPA. Background technique [0002] Currently, in the HSUPA system, the HSUPA scheduler of the base station (NODEB) performs scheduling once in each subframe "n". The scheduler determines the UEs scheduled in the current subframe through scheduling, and allocates the Enhanced Dedicated Channel Absolute Grant Channel (E-AGCH), E-PUCH and Enhanced Dedicated Channel Hybrid Automatic Repeat Request Indicator Channel (E-HICH) for each UE ). [0003] The E-AGCH allocated to the UE is an E-AGCH in the E-AGCH set configured by the radio network controller (RNC) to the UE; the E-PUCH allocated to the UE is a part or all of the resources in the E-PUCH resource pool , and the resource occupied by the E-PUCH allocated to the UE must be a re...
