Problems solved by technology

[0004] However, since the position of the transmission resource used to transmit the reference signal in the traditional method is fixed, the transmission resource used by the device to send the reference signal may conflict with the transmission resource used by the device to send other messages, which affects the transmission performance of the device. In severe cases, it may even cause demodulation and decoding errors, thus affecting the normal transmission of the equipment

Embodiment 1

[0290] This embodiment mainly introduces a method for transmitting a reference signal, and various manners of how to dynamically determine transmission resources for transmitting the reference signal before transmitting the reference signal.

[0291] Next, the reference signal transmission method provided by the embodiment of the present application is described with the accompanying drawings, such as figure 2 As shown, the method includes the following steps:

[0292] 201: The first device acquires a time-domain resource parameter used for sending a reference signal.

[0293] The reference signals in this embodiment of the present application may include different types of reference signals, such as SRS, DMRS, random access reference signal, phase tracking reference signal, channel state information reference signal, positioning reference signal, and the like. The type of reference signal that needs to be sent by the first device may be related to communication requirements...

Embodiment 2

[0417] Through the description of Embodiment 1, it is clarified that the embodiment of the present application can dynamically determine the transmission resources for transmitting reference signals according to the time domain resource parameters of reference signals, thereby reducing the possibility of conflicts with other messages when sending reference signals, and improving system transmission efficiency.

[0418] In this embodiment, however, it will be mainly described how to deal with conflicts between the transmission resources used for transmitting reference signals and the transmission resources used for transmitting messages in the first device, so as to reduce the impact on transmission performance.

[0419] It should be noted that this embodiment can be implemented independently or based on the first embodiment.

[0420] Figure 8 It is a method flowchart of a method for determining a transmission resource of a reference signal provided in an embodiment of the pr...

Embodiment 3

[0528] In this embodiment, in combination with the ninth implementation in Embodiment 2, it will be described under what conditions the first device will perform when the transmission resource used to send the reference signal conflicts with the transmission resource used by the device to send other messages. You can choose not to send part or all of the message processing method.

[0529] Figure 12 It is a method flowchart of a method for determining a message transmission resource provided in an embodiment of the present application, and the method includes the following steps:

[0530] 1201: The first device determines a first resource and a second resource. The first resource is a transmission resource used to transmit a reference signal to be sent, and the second resource is a transmission resource used to transmit a message to be sent.

[0531] For the relevant description of each feature in this step, reference may be made to the description of the corresponding part...

Abstract

The embodiment of the present application discloses a reference signal, a message transmission method, a transmission resource determination method, and a device. When the first device needs to transmit a reference signal, the first device can select from the time slot according to the time domain resource parameters of the reference signal. Determine the transmission resource information related to the transmission resource used to transmit the reference signal, the transmission resource information may include the symbol position of the transmission resource in the time slot and / or the airspace resource on the symbol in the transmission resource, Compared with the traditional method, which can only transmit reference signals through fixed positions, the transmission resources for transmitting reference signals can be dynamically determined according to the time domain resource parameters of reference signals, reducing the possibility of conflicts with other messages when sending reference signals . The transmission resource of the reference signal may also be determined, and when the first resource and the second resource overlap in time domain, the first device may only send part of the reference signal or not send the reference signal to improve its own transmission performance.

Description

technical field [0001] The present application relates to the communication field, in particular to a method for transmitting reference signals and messages, a method for determining transmission resources and related devices. Background technique [0002] With the development of communication technology, the transmission performance requirements of equipment in the communication field are also getting higher and higher. [0003] According to different communication requirements, various types of reference signals need to be transmitted between devices. For example, when the device is a terminal equipment (Terminal Equipments, TE), in order to realize the measurement of the uplink channel, the TE needs to send a channel sounding reference signal (Sounding Reference Signal, SRS); Demodulation reference signal (DMRS); for uplink access, the TE needs to send a random access reference signal; in order to measure the phase noise within the transmission bandwidth, the TE needs to...
