[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] This invention provides a method for selecting small data packet transmission resources. This method can be applied, for example, to a terminal protocol stack. Figure 1 As shown, the method includes:

[0053] Step 100: Before initiating small data packet transmission resource selection, a measurement command is sent to measure the received power of the synchronization signal block reference signal of the current cell.

[0054] In some embodiments, existing protocols propose small packet transmission functionality. Resource selection for small packet transmission is primarily based on several key points. The choice between small packet transmission and non-small packet transmission typically depends on data volume thresholds and reference signal received power thresholds. The choice between using a New Radio Link (NUL) or a Supplemental Uplink Link (SUL) is typically based on the reference signal received power threshold for small packet transmission. When selecting between small packet transmission based on pre-configured resources and small packet transmission based on random access, if there are pre-configured licensed resources with a synchronization signal block greater than the threshold, and the corresponding resources are valid, small packet transmission using pre-configured resources is selected; otherwise, the small packet transmission mode for random access is selected based on the reference signal power threshold for small packet transmission. When the selected carrier has small packet transmission resources for random access with two information exchanges, and the corresponding resources meet the requirements, small packet transmission for random access with two information exchanges is selected; otherwise, when the selected carrier has small packet transmission resources for random access with four information exchanges, and the corresponding resources meet the requirements, small packet transmission for random access with four information exchanges is selected. However, in existing protocols, the direct application of historical measurement results at the start of small packet transmission can lead to inappropriate resource selection. In this step, when the upper layer initiates data transmission, a measurement notification is first sent to measure the received power of the reference signal of the current synchronization block.

[0055] Step 200: Receive the reported current measurement result of the reference signal received power of the current cell synchronization signal block, and perform the small data packet transmission resource selection process based on the current measurement result and the historical measurement results prior to the current measurement result.

[0056] In some embodiments, the measurement results are reported after the measurement is completed, so that when selecting small data packet transmission resources, the selection is based on historical measurement results and current measurement results, rather than simply relying on historical measurement results.

[0057] In the technical solution provided by this invention, before initiating small data packet transmission resource selection, the received power of the synchronization block reference signal of the current cell is first measured. After receiving the current measurement result, resource selection is performed based on the current measurement result and historical measurement results. This allows for the acquisition of the latest received power of the synchronization block reference signal of the current cell, enabling the selection of better transmission resources. In some preferred embodiments, this implementation can be executed by the protocol stack, and the measurement of the latest received power of the synchronization block reference signal of the current cell can be performed by the physical layer, for example.

[0058] As an optional implementation, in step 200, the small data packet transmission resource selection process, based on the current measurement result and historical measurement results prior to the current measurement result, includes:

[0059] When the current measurement results include both historical measurement results and the filtered results of the current measurement results;

[0060] Based on the uplink data volume configured in the network and the filtered results, the small data packet transmission resource selection process is executed.

[0061] In some embodiments, when the deviation between the current measurement result and the historical measurement result is not greater than a predetermined threshold, it indicates that the current received power fluctuation is not significant. Therefore, the historical measurement result and the current measurement result can be filtered before being reported. After receiving the filtered result, a small packet transmission resource selection process is performed based on the uplink data volume configured in the network and the synchronization signal block reference signal threshold. The filtered result is a weighted sum of the historical measurement result and the current measurement result of the synchronization signal block reference signal.

[0062] As an optional implementation, in step 200, the small data packet transmission resource selection process, based on the current measurement result and historical measurement results prior to the current measurement result, includes:

[0063] When the current measurement result includes real-time data of the current measurement result;

[0064] Based on the real-time data of the current measurement results and the historical measurement results, the small data packet transmission resource selection process is executed.

[0065] In some embodiments, when the deviation between the current measurement result and the historical measurement result is greater than a predetermined threshold, it indicates that the current received power has a large fluctuation. Therefore, the current measurement result should be taken as the standard, and the latest measurement result should be directly used as the downlink synchronization signal block measurement indication for small data packet transmission. The current measurement result should be reported in real time. During the resource selection process, the corresponding resource should also be selected according to the rules in the protocol.

[0066] This invention also provides a method for selecting small data packet transmission resources, which can be applied, for example, to the terminal physical layer. Figure 2 As shown, the method includes:

[0067] Step 300: Receive the sent measurement command, and measure the received power of the synchronization signal block reference signal of the current cell according to the measurement command to obtain the current measurement result; wherein, the measurement command is issued by the protocol stack before starting the small data packet transmission resource selection;

[0068] In some embodiments, existing protocols propose small packet transmission functionality. Resource selection for small packet transmission is primarily based on several key points. The choice between small packet transmission and non-small packet transmission typically depends on data volume thresholds and reference signal received power thresholds. The choice between using a New Radio Link (NUL) or a Supplemental Uplink Link (SUL) is typically based on the reference signal received power threshold for small packet transmission. When selecting between small packet transmission based on pre-configured resources and small packet transmission based on random access, if there are pre-configured licensed resources with a synchronization signal block greater than the threshold, and the corresponding resources are valid, small packet transmission using pre-configured resources is selected; otherwise, the small packet transmission mode for random access is selected based on the reference signal power threshold for small packet transmission. When the selected carrier has small packet transmission resources for random access with two information exchanges, and the corresponding resources meet the requirements, small packet transmission for random access with two information exchanges is selected; otherwise, when the selected carrier has small packet transmission resources for random access with four information exchanges, and the corresponding resources meet the requirements, small packet transmission for random access with four information exchanges is selected. However, in existing protocols, historical measurement results are directly applied when small data packet transmission is initiated, which may lead to unreasonable resource selection. In this step, when the upper layer initiates data transmission, the protocol stack first sends a measurement notification to the physical layer to measure the received power of the reference signal of the current synchronization signal block.

[0069] Step 400: Send the measurement results to perform a small data packet transmission resource selection process based on the current measurement results and historical measurement results prior to the current measurement results.

[0070] In some embodiments, the measurement results are reported after the measurement is completed, so that when selecting small data packet transmission resources, the selection is based on historical measurement results and current measurement results, rather than simply relying on historical measurement results.

[0071] In the technical solution provided by the embodiments of the present invention, before starting the small data packet transmission resource selection, the receiving power of the synchronization signal block reference signal of the current cell is first measured. After receiving the current measurement result, the protocol stack selects resources based on the current measurement result and the historical measurement result, thereby obtaining the latest receiving power of the synchronization signal block reference signal of the current cell so as to select better transmission resources.

[0072] As an optional implementation, in step 400, sending the measurement result includes:

[0073] When the deviation between the current measurement result and the historical measurement result exceeds a predetermined threshold;

[0074] The current measurement result is used as the downlink synchronization signal block measurement indication for small data packet transmission, and real-time data of the current measurement result is sent.

[0075] In some embodiments, when the deviation between the current measurement result and the historical measurement result is not greater than a predetermined threshold, it indicates that the current received power fluctuation is not significant. Therefore, the historical measurement result and the current measurement result can be filtered before being reported. A small packet transmission resource selection process is performed based on the uplink data volume configured in the network and the synchronization signal block reference signal threshold.

[0076] As an optional implementation, in step 400, sending the measurement result includes:

[0077] When the deviation between the current measurement result and the historical measurement result does not exceed a predetermined threshold range;

[0078] The current measurement result is filtered together with the historical measurement result, and the filtered result is sent.

[0079] In some embodiments, when the deviation between the current measurement result and the historical measurement result is greater than a predetermined threshold, it indicates that the current received power has a large fluctuation. Therefore, the current measurement result should be taken as the standard, and the latest measurement result should be directly used as the downlink synchronization signal block measurement indication for small data packet transmission. The current measurement result should be reported in real time. During the resource selection process, the corresponding resource will also be selected according to the rules in the protocol.

[0084] When the current measurement result includes real-time data of the current measurement result; the small data packet transmission resource selection process is executed based on the real-time data of the current measurement result and the historical measurement result.

[0085] As an optional implementation, the information receiving module is specifically used for:

[0086] When the current measurement result includes real-time data of the current measurement result; the small data packet transmission resource selection process is executed based on the real-time data of the current measurement result and the historical measurement result.

[0087] This invention also provides a small data packet transmission resource selection device, which is located at the terminal physical layer, such as... Figure 4 As shown, the device includes:

[0089] The information sending module is used to send the measurement results to perform a small data packet transmission resource selection process based on the current measurement results and historical measurement results prior to the current measurement results.

[0091] When the deviation between the current measurement result and the historical measurement result exceeds a predetermined threshold, the current measurement result is used as a downlink synchronization signal block measurement indication for small data packet transmission, and real-time data of the current measurement result is sent.

[0092] As an optional implementation, the information sending module is specifically used for:

[0093] When the deviation between the current measurement result and the historical measurement result does not exceed a predetermined threshold range, the current measurement result and the historical measurement result are filtered, and the filtered result is sent.

[0094] like Figure 5As shown, an exemplary implementation method is provided to illustrate the technical solutions in various embodiments of the present invention, as detailed below:

[0095] When the protocol stack is preparing to start small data packet transmission, it first sends an instruction to the physical layer, instructing the physical layer to measure the received power of the downlink synchronization signal block reference signal for the current cell's small data packet transmission.

[0096] Upon receiving the instruction, the physical layer immediately measures the received power of the downlink synchronization signal block reference signal for the small data packet transmission in the current cell.

[0097] After the measurement is completed, it is determined whether the deviation between the current measurement result and the historical measurement result exceeds a predetermined threshold. This predetermined threshold can be an empirical value or a priori value.

[0098] When the deviation does not exceed the predetermined threshold, the current measurement result and the historical measurement result are filtered and reported as the downlink synchronization signal block measurement indication for small data packet transmission to the protocol stack. When the deviation exceeds the predetermined threshold, the current measurement result is used as the downlink synchronization signal block measurement indication for small data packet transmission, and the real-time data of the current measurement result is sent to the protocol stack.

[0099] When the protocol stack receives real-time data of the current measurement result or filtered data of the current measurement result and historical measurement result, it selects small data packet transmission resources based on the uplink data volume configured by the network and the reference signal reception power threshold of the synchronization signal block, and sends the selection result to the physical layer.
