Embodiment approach

[0086] see figure 1 , is a first exemplary flow chart of the transmission method of the uplink non-orthogonal multiple access system of the present invention. The method can be applied in a terminal and / or a base station. Such asfigure 1 As shown, a preferred implementation of the transmission method of the uplink non-orthogonal multiple access system includes the following steps:

[0087] Step S100, receiving transmission requests sent by a first number of terminals.

[0088] In this implementation manner, the base station may receive transmission requests sent by a first number of terminals that may exist within its coverage area. The first number of terminals includes but is not limited to one or more. For example, when the base station receives transmission requests sent by multiple terminals, it means that the base station can communicate with multiple terminals.

[0089] Step S102, determining the second number of terminals for scheduled access according to the sched...

[0129] see Figure 4 , is a second exemplary flow chart of the transmission method of the uplink non-orthogonal multiple access system of the present invention. Such as Figure 4 As shown, a preferred implementation of the transmission method of the uplink non-orthogonal multiple access system includes the following steps:

[0130] Step S300, receiving transmission requests sent by a first number of terminals.

[0131] In this embodiment, the function of step S300 is the same as that of step S100 in the first embodiment, so it will not be repeated here.

[0132] Step S302: Determine, according to a scheduling rule, a second number of terminals for scheduled access.

[0133] In this implementation manner, the function of step S302 is the same as that of step S102 in the first embodiment, so it will not be repeated here.

[0160] Please refer to Figure 6 , is a third exemplary flow chart of the transmission method of the uplink non-orthogonal multiple access system of the present invention. Such as Figure 6 As shown, a preferred implementation of the transmission method of the uplink non-orthogonal multiple access system includes the following steps:

[0161] Step S600, receiving transmission requests sent by a first number of terminals.

[0162] In this embodiment, the function of step S600 is the same as that of step S100 in the first embodiment, so it will not be repeated here.

Abstract

The invention discloses a transmission method of an uplink non-orthogonal multiple access system. The method comprises the following steps: receiving a transmission request sent by a first number of terminals; determining scheduling access to a second number of terminals according to a scheduling rule; and selecting a corresponding coding and modulation mode from a multiple access table accordingto channel state information of the second number of terminals. According to the transmission method of the uplink non-orthogonal multiple access system disclosed by the invention, different parameterinformation is included in the coding and modulation mode, and then the corresponding coding and modulation mode is selected according to the channel state information of each terminal, so that the scheme meets various transmission rate requirements under different application equipment scenarios and different channel conditions.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a transmission method of a non-orthogonal multiple access system in the technical field of digital information transmission. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are set forth in the claims and detailed description. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In a traditional mobile communication system, a base station needs to communicate with multiple users within coverage. The fourth-generation mobile communication technology (4G) is based on Orthogonal Frequency Division Multiple Access (OFDMA). To a certain extent, it meets the needs of broadband mobile communication applications for a period of time. Orthogonal multiple access technology is simple and flexible to implement. However, network information theory po...
