Embodiment 1

[0025] This embodiment provides a method for allocating resource blocks in a long term evolution system, please refer to figure 1 , figure 1 The schematic flow chart of the method provided in this embodiment specifically includes the following steps:

[0026] Step S101: Randomly determine the starting position of the resource block allocated to the cell.

[0027] In this embodiment, the resource block at the starting position is called the starting resource block.

[0028] In this embodiment, the system randomly assigns a resource block start position to each cell, instead of randomly determining a resource block start position as the resource block start position of each cell.

[0029] In this embodiment, the following method can be used to randomly determine the starting position of the resource block allocated to the cell:

[0030] (1) Number or set labels for resource blocks in the system according to the order of frequency bands from low to high, randomly generate an i...

Embodiment 2

[0040] In order to describe the method provided by the present invention in more detail, this embodiment provides a method for allocating resource blocks in a long term evolution system, please refer to figure 2 , figure 2 It is a flow chart of the method provided in this embodiment.

[0041] Step S201: the cell calculates the sum of the number of RBs required by all scheduling UEs (User Equipment user equipment) in the cell;

[0042] Step S202: The cell calculates the difference between the total number of RBs owned by the system bandwidth and the sum of the number of RBs of UEs in the cell, and the difference is defined as L;

[0043] Step S203: Randomly generate an integer between (0, L], that is, greater than zero and less than or equal to L, defined as M;

[0044] Step S204: Use M#RB as the initial resource block allocated to the cell, starting from M#RB, allocate idle time to all UEs to be scheduled in the cell in the order of RBs from low frequency to high frequency a...

Embodiment 3

[0047] In order to describe the method provided by the present invention in more detail, this embodiment provides a method for allocating resource blocks in a long term evolution system, please refer to image 3 , image 3 It is a flow chart of the method provided in this embodiment.

[0048] Step S301: Determine the total number N of RBs owned by the system bandwidth;

[0049] Step S302: Randomly generate an integer between (0, N], that is, between greater than zero and less than or equal to N, defined as M;

[0050] Step S303: Use M#RB as the initial resource block allocated to the cell, start from M#RB, allocate idle time to all UEs to be scheduled in the cell in the order of RBs from low frequency to high frequency according to the number of RBs required by each UE in the cell RB, M#RB represents the Mth resource block starting from the lowest frequency in the system bandwidth resource block;

[0051] Step S304: all users are allocated resource blocks according to requi...

Abstract

Provided are a method and device for allocating a resource block, and a storage medium. The method comprises: randomly determining a starting position of a resource block allocated to a cell; and allocating the resource block to a user equipment in the cell from the starting position.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for allocating resource blocks in a long-term evolution system. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) project is the evolution of 3G, which improves and enhances the 3G air access technology, adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) technology and MIMO (Multiple-Input Multiple -Output, multiple output multiple input) technology as the only standard for its wireless network evolution. Under the 20MHz spectrum bandwidth, it can provide the peak rate of downlink 100Mbit / s and uplink 50Mbit / s. It improves the performance of cell edge users, increases cell capacity and reduces system delay. LTE is also commonly known as 3.9G, with a data download capability of 100Mbps, and is regarded as the mainstream technology for the evolution from 3G to 4G. [0...
