Problems solved by technology

However, the PF algorithm does not take into account the QoS requirements, especially the delay requirements.
[0015] The allocation of downlink resources in the current LTE system does not consider the service QoS requirements, and when the system allocates resources, the resource utilization rate is low

Embodiment Construction

[0026] Embodiments of the present invention provide a method and device for allocating downlink resources, which are used to maximize PRB resource allocation in combination with QoS requirements and improve resource utilization.

[0027] see figure 1 , a method for allocating downlink resources provided by an embodiment of the present invention includes:

[0028] S101. Determine the currently scheduled RB priority queue according to the QoS requirements of the RBs to be transmitted and the PDCCH capacity;

[0029] S102. Allocate all available PRB resources to the currently scheduled RB priority queue.

[0030] Preferably, S101 specifically includes: determining the priority queue of the RB to be transmitted according to the QoS requirements of the RB to be transmitted; determining the currently scheduled PDCCH resource according to the PDCCH capacity and the PDCCH resources occupied by each RB in the priority queue of the RB to be transmitted RB priority queue.

[0031] As ...

Abstract

The invention provides a distribution method and a distribution device of downstream resources which are used for maximizing distribution of physical resource block (PRB) resources in combination with quality of service (QoS) needs and improving resource utilization rate. The distribution method of the downstream resources includes the steps of confirming radio bearer (RB) priority queue of a present dispatch according to the QoS needs and physical downlink control channel (PDCCH) capacity of the RB to be transmitted and distributing the whole distributable PRB resources to the RB priority queue of the present dispatch, wherein the RB to be transmitted is divided into a non-guarantee bit rate (N-GBR) load and a guaranteed bit rate (GBR) load according to the QoS needs.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a downlink resource allocation method and device. Background technique [0002] In order to better meet the user's QoS (Quality of Service, quality of service) requirements, the LTE (Long Term Evolution, long-term evolution) system adopts a shared channel mechanism, and realizes the resources of each user and each service in the cell through dynamic resource allocation. Sharing, thus providing the possibility for flexible and efficient use of system time domain, frequency domain, and air domain resources. [0003] All LTE services adopt packet switching services, which can be divided into GBR (Guarantee Bit Rate, guaranteed bit rate) bearer and N-GBR (Non-Guarantee Bit Rate, non-guaranteed bit rate) bearer according to QoS level. The GBR bearer is determined according to the guaranteed bit rate. The rate of the GBR bearer must be satisfied, and the occurrence rate of ...
