[0042] The signal transmission method, device, electronic device, and medium of embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0043] Figure 2Flow chart of a signal transmission method according to an embodiment of the present disclosure. It should be noted that the signal transmission method of this embodiment can be applied to a signal transmission device, which can be configured in an electronic device or a chip, so that the electronic device or the chip can perform a signal transmission function.

[0044] Among them, the electronic device can be any device with computing capabilities, such as a terminal device, a personal computer (PC), a mobile terminal, a server, a controller in a vehicle, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, etc., which are hardware devices with various operating systems, touch screens, and / or display screens. Among them, in the following embodiments, the execution entity is taken as an example of an electronic device for description.

[0045] As Figure 2 shown, the method includes the following steps:

[0046] Step 201, obtain the uplink signal and downlink signal scheduled by the downlink control information DCI; there is a flexible symbol resource allocation conflict between the uplink signal and the downlink signal.

[0047] In the embodiment of the present disclosure, the downlink signal scheduled by the downlink control information (DCI) may include at least one of the following: physical downlink shared channel (PDSCH) signal; channel state information reference signal (CSI-RS).

[0048] In the embodiment of the present disclosure, the uplink signal scheduled by the DCI may include at least one of the following: the uplink signal scheduled by the DCI includes at least one of the following: physical uplink shared channel (PUSCH) signal; physical uplink control channel (PUCCH) signal; physical random access channel (PRACH) signal; sounding reference signal (SRS).

[0049] Among them, the flexible symbol resource can be the flexible symbol resource in the time division duplex mode. The time division duplex mode means that receiving and sending are performed on different time slots of the same carrier, so as to separate the receiving channel and the sending channel through time.

[0050] Among them, as Figure 3 shown, it is a schematic diagram of flexible symbol resources. In Figure 3 , time slot (slot) N is flexible symbol resources, and all 14 symbols (Sym) in slot N are flexible symbols (Flexible symb).

[0051] Step 202, determine the signal priority of the uplink signal and the signal priority of the downlink signal.

[0052] In the embodiment of the present disclosure, before step 202, the terminal device may further perform the following process: set signal priorities for at least one uplink signal and at least one downlink signal scheduled by DCI; the signal priority is the signal priority of at least one uplink signal and at least one signal in the flexible symbol resources.

[0053] Among them, the terminal device may set the same signal priority for at least one uplink signal scheduled by DCI, for example, it may be the first signal priority; the terminal device may set the same signal priority for at least one downlink signal scheduled by DCI, for example, it may be the second signal priority. Among them, the first signal priority may be less than the second signal priority.

[0054] Among them, in the case where at least one uplink signal scheduled by DCI includes PUSCH signal, PUCCH signal, PRACH signal and SRS signal, and at least one downlink signal scheduled by DCI includes PDSCH signal and CSI-RS signal, the terminal device may set the first signal priority for PUSCH signal, PUCCH signal, PRACH signal and SRS signal, and the terminal device may set the second signal priority for PDSCH signal and CSI-RS signal.

[0055] Step 203, in the case where the signal priority of the downlink signal is greater than the signal priority of the uplink signal, perform flexible symbol resource allocation processing on the downlink signal.

[0056] In the embodiment of the present disclosure, after step 203, the terminal device may further perform the following process: in the case where the signal priority of the downlink signal is greater than the signal priority of the uplink signal, stop performing flexible symbol resource allocation processing on the uplink signal.

[0057] Among them, in the case where the signal priority of the downlink signal is greater than the signal priority of the uplink signal, stopping the flexible symbol resource allocation processing on the uplink signal is to avoid the uplink signal preempting the flexible symbol resources, that is, to avoid the terminal device canceling the occupancy of the flexible symbol resources by the downlink signal through the partial cancellation capability, and to avoid the terminal device performing flexible symbol resource allocation processing for the uplink signal.

[0058] Among them, the terminal device first performs flexible symbol resource allocation processing on the downlink signal, which can avoid the situation that after the terminal device performs flexible symbol resource allocation processing for the uplink signal and then cancels the occupancy of the flexible symbol resource by the uplink signal through the partial cancellation capability, thereby reducing the processing volume of the terminal device and timely performing flexible symbol resource allocation processing for the downlink signal, thereby improving the resource allocation efficiency and further improving the transmission efficiency of the downlink signal.

[0059] Among them, as Figure 4 shown, it is a schematic diagram of flexible symbol resource allocation for the downlink signal. Among them, in slot N, the flexible symbols allocated to the downlink signal can be, for example, Sym8 to Sym13. Correspondingly, the terminal device cannot allocate any one of the symbols from Sym8 to Sym13 to the uplink signal.

[0060] Among them, when there is a flexible symbol resource allocation conflict between the downlink signal and the uplink signal, that is, when the downlink signal and the uplink signal need to use the flexible symbol resources at the same position, after the terminal device performs flexible symbol resource allocation processing on the downlink signal, it can stop performing flexible symbol resource allocation processing on the uplink signal. Among them, the uplink signal and the downlink signal need to use the flexible symbol resources at the same position. For example, both the uplink signal and the downlink signal need to use the flexible symbol of Sym8.

[0061] Among them, when there is no flexible symbol resource allocation conflict between the downlink signal and the uplink signal, that is, when the downlink signal and the uplink signal use flexible symbol resources at different positions, after the terminal device performs flexible symbol resource allocation processing on the downlink signal, it can continue to perform flexible symbol resource allocation processing on the uplink signal. For example, in Figure 4 it, the flexible symbols of Sym8 to Sym13 can be allocated to the downlink signal; and the flexible symbols of Sym1 to Sym6 can be allocated to the uplink signal.

[0062] Step 204, transmit the downlink signal based on the allocated flexible symbol resources.

[0063] In the signal transmission method of the embodiments of the present disclosure, by obtaining the uplink signal and the downlink signal scheduled by the downlink control information DCI; there is a flexible symbol resource allocation conflict between the uplink signal and the downlink signal; determining the signal priority of the uplink signal and the signal priority of the downlink signal; when the signal priority of the downlink signal is greater than the signal priority of the uplink signal, performing flexible symbol resource allocation processing on the downlink signal; transmitting the downlink signal based on the allocated flexible symbol resources; among them, the downlink signal with a higher signal priority is more important, and the flexible symbol resources are preferentially allocated to the downlink signal with a higher priority, which can ensure the timely transmission of important downlink signals, avoid the terminal device from losing the network, and avoid the wireless link of the terminal device from disconnecting, thereby improving the communication efficiency.
