Embodiment 1
[0026] The method embodiment of the present application embodiment can be performed in a mobile terminal, a computer terminal, or a similar computing device. Take the mobile terminal as an example. figure 1 It is a hardware configuration block diagram of a mobile terminal of a transmission method of a reference signal of the present disclosure. Such as figure 1 As shown, the mobile terminal 10 can include one or more ( figure 1 Only one) processor 102 (processor 102 can include, but is not limited to, a processing apparatus for storing data, and a transmission device for storing data, and a transmission device for communication function 106. One of ordinary skill in the art will appreciate that figure 1 The structure shown is intended to be schematic, and does not limit the structure of the electronic device. For example, mobile terminal 10 can also include ratio figure 1 More or fewer components shown, or have figure 1 Different configurations.
[0027] The memory 104 can be used...

[0055] There are a variety of reference signals in 5G NR, which may also be referred to as pilot, and these pilots have their respective functions. The main pilot types include:
[0056] Downlink pilot: including downlink demodulation reference signal (DLDMRS), a DLDMRS, channel status information reference symbol CSI-RS, DL PTRS, TRS; DL DMRS main function is used for downlink data demodulation, DL PTRS main Used in downlink estimation phase noise, improve performance. CSI-RS is divided into a variety of CSI-RS for beam management; CSI-RS for the CSI measurement for downlink channels. TRS is primarily used for time frequency offset.
[0057] Upstream pilot: including uplink demodulation reference signal UL DMRs, channel detection reference signal (SoundingReference Signal, referred to as SRS), UL PTRS; UL DMRS main function is used for downlink data demodulation. The role of the SRS is for the upstream CSI measurement. UL PTRS is mainly used for uplink estimation phase noise and ...

[0084] For the first class reference signal and the second type of reference signal, a collision may occur on a partial slot, and there is no collision on some time slots. For a high-level signaling configuration for the first class reference signal, the second class reference signal is a physical layer signaling configuration. High-level signaling is generally longer to configure updates, and physical layer signaling can perform dynamic configuration parameters for each time slot, such as Figure 7 Indicated.
[0085] In the slot without conflict, the configuration of the second type of reference signal can be selected from the set X, and the configuration of the second class reference signal can be selected in the configuration, Y is the subset of X. In fact, this is a configuration limit on the second type of reference signal.
[0086] The following row pilots will be described as an example:
