Problems solved by technology

The main problem with related technologies is that the transmission strategy is determined entirely according to the type of channel or signal, which is not flexible, and the resource utilization rate is still not high
[0005] For example: conflicts between potential control regions and some reference signals, such as figure 1 as shown, figure 1 It is a schematic diagram of signal conflict in the related technology of the present invention. In the control area CORESET configured by the terminal, no matter whether there is downlink control signaling (Downlink control signaling, DCI) sent, it cannot be used for channel state information reference signal (Channel state information reference signal, CSI-RS), and tracking reference signal TRS and other types of reference signals, resulting in waste of resources
[0006] In the uplink, although the conflict between the uplink sounding reference signal SRS and the uplink Physical uplink control channel (PUCCH) is not the same as that in the downlink, the essence of the problem is the same, and resources will be wasted
[0007] For the above-mentioned problems existing in related technologies, no effective solution has been found yet

Embodiment 1

[0026] The network architecture in which the embodiments of the present application can operate includes: a sending end and a receiving end, wherein the sending end and the receiving end perform signal interaction.

[0027] In this embodiment, a method for sending a signal running on the above-mentioned network architecture is provided, figure 2 is a flowchart of a method for sending a signal according to an embodiment of the present invention, such as figure 2 As shown, the process includes the following steps:

[0028] Step S202, configure or agree on multiple transmission modes or conflict handling modes of the first signal;

[0029] Step S204, when there is a second signal conflicting with the first signal, select a transmission mode or a conflict handling mode of the first signal according to the judgment information;

[0030] Step S206, sending the first signal according to the sending method or the conflict handling method.

[0031] Through the above steps, when th...

Embodiment 2

[0064] This embodiment also provides a sending and receiving apparatus, which is used to implement the above-mentioned embodiments and preferred implementations, and the descriptions that have been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that implements a predetermined function. Although the apparatus described in the following embodiments is preferably implemented in software, implementations in hardware, or a combination of software and hardware, are also possible and contemplated.

[0065] Figure 4 is a structural block diagram of a signal transmitting apparatus according to an embodiment of the present invention, such as Figure 4 As shown, the device includes:

[0066] The preprocessing module 40 is used to configure or agree on multiple transmission modes or conflict handling modes of the first signal;

[0067] a selection module 42, configured to select a transmission mode or a conflict handli...

Embodiment 3

[0075] The solution of this embodiment includes two aspects, a signal sending method and a signal receiving method. The configuration of the control area allows one or more, for the discrete control area, it may occupy more frequency domain resources and support the sharing of multiple users. However, whether there is DCI being sent in the control area of ​​each time slot and whether it is occupied or not are dynamically changed. The transmission of reference signals should be allowed when there is no occupancy, or when there are some available resources in the control region. Image 6 It is a schematic diagram of signal transmission and signal reception in this embodiment.

[0076] Methods of sending signals, including:

[0077] Step 101: multiple transmission modes of the transmitter configuration or the agreed signal of the transmitter and receiver;

[0078] Further, the multiple transmission methods include a collision handling method when colliding with other signals. ...

Abstract

The present invention provides a signal sending and receiving method and device, a storage medium, and an electronic device, wherein the signal sending method includes: configuring or agreeing on multiple sending methods or conflict handling methods of the first signal; when the first signal exists When the second signal conflicts with it, select the sending mode or the conflict handling mode of the first signal according to the judgment information; and send the first signal according to the sending mode or the conflict handling mode. The present invention solves the technical problem that the resource utilization rate is too low when sending conflicting signals in the related art, improves the sending flexibility when the signal conflicts, thereby improving the resource utilization rate.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for transmitting and receiving signals, a storage medium, and an electronic device. Background technique [0002] There are various reference signals (reference signals) in 5G (New Radio, NR) in the related art, which can also be generally referred to as pilots, and these pilots have respective functions. Downlink pilot: including DL DMRS (downlink demodulation reference signal), CSI-RS (channel state information reference signal), DL PTRS (downlink phase tracking reference signal), TRS (timing reference signal); the main function of DL DMRS is to use For downlink data demodulation, DL PTRS is mainly used for downlink estimation of phase noise to improve performance. CSI-RS is divided into multiple types: CSI-RS used for beam management; CSI-RS used for CSI measurement of downlink channels. TRS is mainly used for time-frequency offset tracking. Up...
