Problems solved by technology

[0006] In the prior art, when PTRS is configured, the impact of inter-carrier interference caused by phase offset on the performance of high-frequency communication systems is hardly considered, especially when the modulation order is high, the inter-carrier interference of high-frequency communication systems cannot be accurately estimated. High bit error rate, resulting in low spectral efficiency

Embodiment Construction

[0050] Embodiments of the present application are described below with reference to the drawings in the embodiments of the present application.

[0051] The term "plurality" in this application means two or more. The term "and / or" in this application is only an association relationship describing associated objects, indicating that there may be three relationships, for example, A and / or B, which may mean: A exists alone, A and B exist simultaneously, There are three cases of B alone. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship. The terms "first", "second" and the like in this application are used to distinguish different objects, and do not limit the order of the different objects.

[0052] The technical solution provided by this application can be applied to various communication systems using beam scanning technology, for example, using beam scanning technology on the basis of existing communicatio...

Abstract

The present application discloses a reference signal transmission method and device, the method comprising: generating one or more OFDM symbols, at least one OFDM symbol includes a PTRS resource block, and the PTRS resource block includes a PTRS sequence of Y elements, the The last X elements of the PTRS sequence, at least two of the three sequences of the first Z elements of the PTRS sequence, the PTRS resource block occupies a plurality of consecutive resource elements RE; wherein, X, Y, and Z are all integers; The one or more OFDM symbols are sent; the above method and device reduce inter-carrier interference, thereby improving spectrum efficiency.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a reference signal transmission method and device. Background technique [0002] With the development of network systems, the demand for communication rate and capacity is increasing, and the demand for high-frequency resources is also increasing. The next-generation wireless communication network with a working frequency band above 6GHz, such as the fifth generation mobile communication (5thgeneration, 5G) , can provide ultra-high-speed data communication services. In the frequency range above 6 GHz, the frequency bands that can be used for the next generation wireless communication network include frequency bands at 28 GHz, 39 GHz, 60 GHz, 73 GHz and so on. High-frequency communication systems above 6GHz have notable features such as large bandwidth and highly integrated antenna arrays, making it easy to achieve high throughput. However, as the frequenc...
