example 1

[0615] Example 1: The network device or terminal device determines the time-domain resource location of the chunks according to the following calculation method:

[0616] PTRS(l,x)=x·N'+Δt+l

[0617] When the configuration information includes the offset parameter Δt, the network device or terminal device may perform calculation according to the configuration information. Among them, x and l respectively represent the position of the lth PTRS symbol in the xth chunk, and the number X of chunks in a DFT-s-OFDM symbol and / or the number L of PTRS symbols contained in a chunk, if x and l Both start counting from 0, then the value range of x is 0≤x≤X-1, and the value range of l is 0≤l≤L-1. (you can refer to Figure 16 indication) among them, is the lower integer symbol, N is the number of all (modulation) symbols of the DFT-s-OFDM symbol before DFT, where N' represents between any two adjacent chunks, the first symbol of the first chunk and the first symbol of the first chunk ...

example 2

[0628] Example 2: The network device or terminal device determines the time-domain resource location of the chunks according to the following calculation method:

[0629] PTRS(l,x)=x·N'+Δt+l

[0630] Similar to the above example 1, when the configuration information includes the offset parameter Δt and the interval parameter N′, the network device or terminal device may perform calculation according to the above manner. In an embodiment, the configuration information may include first configuration information and / or second configuration information, the first configuration information includes Δt, and the second configuration information includes the N′.

[0631] Similar to Example 1, but the specific configuration method is: when the configuration information includes the offset parameter Δt and also includes the interval parameter N', the network device or terminal device determines that the xth The position of the first PTRS symbol in the chunk can be specifically determi...

Abstract

The present application provides a PTRS processing method and device. The method comprises following steps: a terminal receives first indication information and second indication information from a network device; the first indication information is used to indicate a time domain position where the terminal transmits the PTRS; the second indication information is used to instruct the terminal to map an offset amount of an initial time domain position of the PTRS; the terminal maps the PTRS to one or more DFT-S-OFDM symbols according to the first indication information and the second indicationinformation; the terminal transmits the one or more DFT-S-OFDM symbols. By DFT-S-OFDM symbol-level shifting of PTRS mapped to DFT-S-OFDM symbols, collision of PTRS between terminals can be avoided toa certain extent, so that phase tracking accuracy can be improved.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a phase tracking reference signal (PhaseTracking Reference Signal, PTRS) processing method and device. Background technique [0002] In the existing wireless communication networks (such as 2G, 3G and 4G networks), the working frequency bands of the communication systems are all in the frequency range below 6GHz, but the available working frequency bands in this frequency range are less and less, which cannot meet the increasing demands. Increased communication needs. There are a large number of underutilized frequency bands in the frequency range above 6GHz. Therefore, the industry is researching and developing next-generation wireless communication networks (such as 5G networks) with operating frequency bands above 6 GHz to provide ultra-high-speed data communication services. [0003] In the frequency range above 6 GHz, the frequency bands that can be used for th...
