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

[0087] Under normal circumstances, the E-PUCH resource pool allocated to NODEB by the RNC occupies several complete time slots and several incomplete time slots. Therefore, in any subframe, the E-PUCH resource pool on one HSUPA carrier can be divided into two rectangular E-PUCH resource pools, and these two resource pools can be divided as needed. Preferably, the first one consists of several complete time slots. The second one is composed of one or more incomplete time slots. In this embodiment, the two rectangular resource pools A and B obtained by dividing according to needs are explained. Preferably, the first rectangular E-PUCH resource pool A is constituted by several complete time slots, and the second rectangular resource pool B is constituted by partial resources of 1 time slot.

Embodiment 2

[0166] In this embodiment, for a UE that supports non-rectangular E-PUCH resource allocation, when the NodeB needs to allocate a non-rectangular E-PUCH resource to the UE, the allocated non-rectangular E-PUCH resource is divided into multiple rectangular resources. 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 information about a rectangular resource. When selecting the E-AGCH, the selection can be made according to information such as the number, and preferably, when the same UE is continuously scheduled, try to select the E-AGCH previously allocated to the UE.

[0167] Wherein, when each E-AGCH carries information about a rectangular resource, the E-AGCH format still uses the existing format, and the values ​​of the fields except the CRRI field and the TRRI field are the same as the existing determination method. The CRRI field and ...

Abstract

The present invention provides a method for allocating non-rectangular E-PUCH resources in HSUPA. When NodeB allocates E-PUCH resources to UEs, it allocates non-rectangular E-PUCH resources to UEs that support non-rectangular E-PUCH resource allocation, and The allocated non-rectangular E-PUCH resources are divided into multiple rectangular resources, and the time slots and node information of the multiple rectangular resources are notified to the UE through the E-AGCH. In this way, the purpose of allocating non-rectangular E-PUCH resources to the UE and notifying the UE of the allocated resources can be achieved, so that the UE can use the non-rectangular E-PUCH resources for data transmission and improve the peak uplink 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...
