Resource allocation device, resource allocation system and resource allocation method

Abstract

An embodiment of the invention discloses a resource allocation device capable of solving the problem about semi-static scheduling compatibility between VMIMO (virtual multiplex input multiplex output) and VoIP (voice over internet protocol) and improving VoIP capacity. The resource allocation device comprises a determination unit and an allocation unit. The determination unit is used for determining the number of resource blocks needed by user equipment in need of uplink, wherein the number of the resource blocks of each of the first user equipment in need of uplink and the second user equipment in need of uplink is M which is a positive integer. The allocation unit is used for allocating the resource blocks in a first sub group in a first resource group to the first user equipment and allocating the resource blocks in a second sub group in the first resource group to the second user equipment, wherein the first resource group comprise a plurality of sub groups including the first sub group and the second sub group, and each sub group comprises M resource blocks. The embodiment of the invention further provides a resource allocation system and a resource allocation method.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a resource allocation device, system and method. Background technique [0002] In a Long Term Evolution (LTE) system, when wireless communication resources are utilized in a shared resource allocation manner, relevant control information is required for each transmission, and uplink resources are relatively limited. For real-time services with fixed data packet size and regular arrival time interval, LTE system introduces a new resource allocation method, that is, semi-static scheduling technology. In simple terms, semi-static scheduling refers to the resource transmission process of LTE. At the beginning, the base station indicates the current resource allocation information of the user equipment through the control channel area. When the user equipment recognizes that it is semi-persistent scheduling, it saves the current resource allocation information and...

Problems solved by technology

[0003] Taking a typical voice call (Voice Over IP, VoIP) service as an example, the uplink resource supporting VoIP service capacity is basically semi-statically scheduled at present, and its data packet arrival period is 20ms, that is, VoIP data packets at intervals of 20ms use the same modulation Modulation and Coding Scheme (MCS) and radio link bearer (Radio Bear, RB) positions are scheduled, but because VoIP adopts semi-static MCS does not change, and VMIMO is affected by interference between different user equipment , if a certain error packet convergence is guaranteed, the MCS needs to change with the information of the paired user equipment. The current semi-static VoIP and VMIMO are not compatible with each other, which limits the capacity of VoIP
