Embodiment Construction

[0058] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0059] PDMA technology (Pattern Division Multiple Access, Pattern Division Multiple Access) is a representative non-orthogonal multiple access technology. In the following embodiments, PDMA technology will be used as an example for illustration, but this does not mean It means that the technical solution provided in the embodiment of the present invention can only be used in PDMA technology. In fact, based on the commonality of non-orthogonal multiple access technology, after understanding the technical concept of this application, those skilled in the art will make corresponding modifications That is, it can be used for other non-orthogonal multiple access technologies. The PDMA will be briefly introduced below.

[0060] PDMA technology utilizes the asymmetry of multi-user channels, and realizes multi-dimensional non-orthogonal signal superposition tra...

Abstract

The invention discloses a method and apparatus for transmitting and receiving an uplink demodulation pilot carrier. The method comprises: determining non-orthogonal multiple access basic transmission units of a transmission service at the time of transmission, wherein each of the basic transmission units uses a non-orthogonal multiple access pattern vector to transmit data; using a demodulation pilot carrier resource to transmit a demodulation pilot signal in each non-orthogonal multiple access basic transmission unit; at the time of reception, acquiring an uplink demodulation pilot signal from a received signal on a time-frequency resource occupied by the non-orthogonal multiple access basic transmission units. The method and apparatus solve the need for uplink demodulation pilot resource growth in the case that high-load multi-user data multiplexes the time-frequency resources in a non-orthogonal manner.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for sending and receiving uplink demodulation pilots. Background technique [0002] The fifth-generation mobile communication system (5G for short) proposes technical requirements such as Gbit / s user experience rate, ultra-high traffic density, ultra-large number of connections, improved spectrum efficiency, and reduced delay. The domestic IMT-2020 (5G) promotion group proposed four typical application scenarios for 5G: wide-area coverage for mobile Internet applications, high-capacity coverage scenarios for hotspots, low-power large connections, and low latency for mobile Internet of Things applications high-reliability scenarios, and considers that non-orthogonal multiple access technology is a key technology that can be applied to these typical scenarios. At present, non-orthogonal multiple access technologies in the industry general...
