Background
The internet of things, namely the internet of everything, has been gradually applied in recent years, and is mainly applied to application scenes such as intelligent furniture, intelligent wearing equipment, vehicle-vehicle interconnection and the like.
Specifically, most devices that execute the internet of things are connected by an NR (new air interface) network or the like. For example, the user terminal may be in an internet of things with the controlled LED display by accessing the NR network of the controlled LED display. Therefore, a control instruction can be sent to the controlled LED display screen to adjust the display of the controlled LED display screen and the like.
However, the current NR connection method is mostly connected to a cell, and if the NR connection method is connected across cells, the control delay is relatively high due to the fact that a control command needs to pass through a core network, so that it is difficult for a controlled device, such as a controlled LED display, to respond to control at the first time, which results in poor user experience.

It should be noted that the scheme in the embodiment of the present application may also be applied to other communication systems, and the corresponding names may also be replaced with names of corresponding functions in other communication systems.
It should be understood that fig. 1 is a simplified schematic diagram of an example for ease of understanding only, and that other network devices, and/or other terminal devices, not shown in fig. 1, may also be included in the communication system.
The method provided by the embodiment of the present application will be specifically described below with reference to fig. 2.
Exemplarily, fig. 2 is a schematic flowchart of a control method of an intelligent LED display screen based on a 5g control system according to an embodiment of the present application. The method may be applied to communication between the network device and the terminal device shown in fig. 1. Such as between the first gNB and the terminal device. The intelligent LED display screen resides in a cell of the first gNB, the terminal equipment resides in a cell of the second gNB, and the first gNB and the second gNB are the same or different gNBs. As shown in fig. 2, the method comprises the steps of:
s201, the first gNB receives first control information from the terminal device.
Wherein, the first control information carries: a control field, the controllable field for instructing the smart LED display to perform a first action. The first control information may be received via forwarding of the second gNB.
And S202, the first gNB determines the emergency degree parameter of the first action according to the control field, determines a first time domain interval corresponding to the emergency degree parameter, and determines a candidate time domain position of the PDSCH according to the first time domain interval.
The first time interval may be: a time domain interval between a time domain position where the first control information is received and a candidate time domain position of the PDSCH (physical sidelink). The PDSCH may be used to carry first control information. If the urgency level parameter indicates a higher urgency level, the first inter-domain interval is smaller, for example, if the urgency level parameter is level 1, the first inter-domain interval may be 0, i.e., the time domain positions are adjacent, if the urgency level parameter is level 2, the first inter-domain interval may be 2, i.e., the time domain positions are separated by 1 time slot, and so on.
Wherein the degree of urgency by the first action is from no urgency to urgency, and the first action may include: adjusting display content, adjusting display brightness, lighting a display screen, or extinguishing the display screen.
S203, the first gNB determines the actual time domain position of the PDSCH according to the candidate time domain position of the PDSCH.
The first gNB can determine whether the first time domain resource corresponding to the candidate time domain position of the PDSCH in the time frequency resource pool is idle. Wherein the first time domain resources occupy one or more time slots in the time domain, in other words, one PDSCH may occupy one or more time slots.
If not, the first gNB may determine whether a first preset number of first symbols are idle in the one or more time slots, where the first preset number is a number of symbols required for transmitting the PDSCH, in other words, the PDSCH may occupy the first preset number of symbols in the one or more time slots. Therefore, if there is a first preset number of first symbols that are idle, the first gNB may determine that the time domain position corresponding to the first symbol is the actual time domain position of the PDSCH.
Optionally, when determining the symbols, the first gNB may obtain the first preset number of second symbols by exchanging time domain positions of a next symbol and an adjacent previous symbol in the sequence from time to time in the time domain. The first preset number of second symbols are distributed continuously in the time domain, so that the time domain positions where the first preset number of second symbols are located are the actual time domain positions of the PDSCH. Alternatively, when determining the symbols, the first gNB may also determine a first preset number of first symbols in one or more time slots in a time domain sequence from back to front.
Further, the first gNB may also determine frequency-domain resources corresponding to the PDSCH in the actual time-domain location. For example, the first gNB may determine, in the time-frequency resource pool, a second preset number of frequency-domain resources corresponding to the actual time-domain position. Wherein the second preset number of frequency domain resources are used for transmitting the PDSCH. Specifically, the first gNB may determine whether the second preset number of frequency-domain resources are contiguous in the frequency domain. If the first gbb is continuous, the first gbb may randomly determine a corresponding relationship between each frequency domain resource and each PDSCH in a second preset number of frequency domain resources and a plurality of sub-PDSCHs. If not, the first gNB may sequentially determine, in the second preset number of frequency domain resources and the plurality of sub-PDSCHs, a correspondence between each frequency domain resource and each sub-PDSCH according to a sequence from high to low of the frequency domain.
S204, the PDSCH is sent to the intelligent LED display screen by the first gNB at the actual time domain position, so that the intelligent LED display screen can execute the first action.
Wherein, as described above, the first gNB may transmit the PDSCH to the smart LED display at an actual time domain location as well as a frequency domain resource.
Referring to fig. 3, an embodiment of the present application provides a control device 300 for an intelligent LED display screen based on a 5g control system. The apparatus 300 may be applied to a first gNB, where an intelligent LED display screen resides in a cell of the first gNB, and the apparatus 300 may include: a transceiver module 302 and a processing module 301.

the transceiver module 302 is further configured to send a PDSCH to the intelligent LED display screen at the actual time domain position, so that the intelligent LED display screen executes the first action.
Optionally, the processing module 301 is further configured to determine whether a first time domain resource corresponding to the candidate time domain position of the PDSCH in a time frequency resource pool is idle, where the first time domain resource occupies one or more time slots in a time domain; if not, judging whether a first preset number of first symbols are idle in the one or more time slots, wherein the first preset number is the number of symbols required for sending the PDSCH; and if the first preset number of first symbols are idle, determining that the time domain position corresponding to the first symbols is the actual time domain position of the PDSCH.
Optionally, the processing module 301 is further configured to, according to a time domain sequence from first to last, adjust time domain positions of a next symbol and an adjacent previous symbol in the spaced symbols to obtain a first preset number of second symbols, where the first preset number of second symbols are distributed continuously in a time domain, and a time domain position where the first preset number of second symbols is located is an actual time domain position of the PDSCH.
Optionally, the processing module 301 is further configured to determine the first preset number of first symbols in the one or more time slots in a time sequence from back to front in a time domain.

In this way, it is achieved that both the most advanced time domain position and the frequency domain resources at that time domain position are determined to ensure reliable transmission of the PDSCH.
Optionally, the processing module 301 is further configured to determine whether the second preset number of frequency domain resources are continuous in a frequency domain; if the number of the frequency domain resources is continuous, randomly determining the corresponding relation between each frequency domain resource and each sub-PDSCH in the second preset number of the frequency domain resources and the plurality of sub-PDSCHs; and if not, sequentially determining the corresponding relation between each frequency domain resource and each sub-PDSCH in the second preset number of frequency domain resources and the plurality of sub-PDSCHs according to the sequence of the frequency domains from high to low. Since the frequency domain resources in the high frequency band are generally more likely to be idle, the multiple consecutive sub-PDSCHs can be determined most quickly by analyzing the frequency domains in order from high to low.
Optionally, the first action is from urgent to urgent according to the urgency of the first action, and the first action includes: adjusting display content, adjusting display brightness, lighting a display screen, or turning off the display screen.
