Embodiment Construction

[0038] Such as Figure 2 ~ 5 As shown, the present invention discloses a resource allocation method based on a MMTC layered access frame.

[0039] Overall, the present invention proposes a model of multi-level resource allocation for the proposed MMTC network layering. First, in the first layer network model, communication between base stations and LTE users, and communication between the base station and the aggregation node user. Therefore, the first-level resource allocation refers to the base station allocates the resource block to the convergence node user, and we can interfere with the interference between the user in a certain resource block, as well as the interference of the aggregation node user and the LTE user Modeling analysis, determine if the resource block can be occupied by the aggregation node. In the second layer network model, communication between the MTC user and the aggregation node user is mainly included. Therefore, the second level resource allocation is m...

Abstract

A resource allocation method based on the mMTC layered access framework, comprising the following steps: S1, a first-level resource allocation step, the base station allocates resource blocks to convergence node users; S2, a second-level resource allocation step, the base station allocates Resource blocks are subdivided into sub-carrier groups, and multiple MTC users matched to each sub-carrier group form a user group to complete the mutual matching of sub-carrier groups and user groups; S3, the third-level resource allocation step, in each In the user group, according to the subcarrier group obtained in the second-level resource allocation step, each subcarrier group is allocated to the user according to the allocation rule, and the user completes the power allocation according to its own location and service type. The invention can effectively improve the performance and spectrum utilization rate of the whole network framework system.

Description

Technical field [0001] The present invention relates to a resource allocation method, and more particularly to a resource allocation method based on the MMTC hierarchical access frame, which belongs to the field of wireless communication technology. Background technique [0002] MMTC is one of the three main application scenarios of Massive Machine-Type Communication. In this application scenario in this application, there will be a hundred billion to access the network, and the data type sent by various devices in various devices is different. If the MTC device in a region needs to be independently access the base station of the area, this will bring a lot of burden to the base station, and will also cause serious resource waste and signaling conflicts. At the same time, at the same time, the massive access of the MMTC system also has some features, namely low power consumption, suddenness, and short frame length business. Massive access is mainly used to solve the extensible, e...
