Embodiment Construction

[0078] Embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0079] figure 2 A schematic diagram of a communication system is given. The system can be widely used to provide various types of communication such as voice, data and so on. The communication system may have multiple wireless communication devices, for example, may include at least one terminal device 200 to communicate with the radio access network. The wireless access network is connected to the core network. The wireless access network includes at least one network device 100 ( figure 1 only one is shown). The network device 100 may be any device with a wireless transceiver function. Including but not limited to: base stations (for example, base station NodeB, evolved base station eNodeB, base station in the fifth generation (the fifth generation, 5G) communication system, base station or network equipment in future communi...

Abstract

The invention provides an information transmission method and device. The method is characterized in that the method includes the steps: determining time domain density of a PTRS (phase tracking reference signal); determining frequency domain density of the PTRS according to an available bandwidth, or determining the frequency domain density of the PTRS according to scheduling or an available RB (resource block); mapping the PTRS to one or more OFDM (orthogonal frequency division multiplexing) symbols according to the time domain density and the frequency domain density; and transmitting a signal that includes the OFDM symbols where the PTRS is mapped. The invention also discloses a corresponding device. By adopting the technical solution of the present invention, the method can avoid thejump of the number of PTRSs near the threshold of the scheduling bandwidth, takes into account the accuracy and spectral efficiency of the common phase error estimation, and can achieve the uniform mapping of the PTRS within the scheduling or available bandwidth, thereby achieving the reasonable configuration of the PTRS.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to signal transmission in a wireless communication system. Background technique [0002] With the increasing demand for communication, the next-generation wireless communication network (such as the fifth generation mobile communication (5G) th generation, 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. At the same time, compared with the existing wireless communication network, the high-frequency communication system will suffer from more serious mid-radio frequency distortion, e...
