Description

Peak data rate control method, device, equipment and medium
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a medium for controlling a peak data rate.
Background
In a New air interface (NR) technology of 5G, a terminal device with reduced supporting capability (Reduced Capability, redCap) is provided, and the RedCap terminal has advantages of low cost, low complexity, and the like, and can support the use of the NR technology by a 5G internet of things terminal with a low rate. It is also provided that the ratio of the sum of all transport block sizes (Transport Block Size, TBS) of the base station capable of scheduling the RedCap terminals within a slot (slot) to the time length of the slot needs to be within the constraints of the peak data rate, i.e. the maximum data rate. Further, the peak data rate supported by the RedCap terminal is associated with a maximum TBS, and decreasing the peak data rate may decrease the maximum TBS supported by the RedCap terminal, thereby decreasing the complexity of the RedCap terminal.
At present, the solution for reducing the complexity of the RedCap terminal is to limit the related parameters reported by the RedCap terminal to the base station, more specifically, the product of the modulation order, the number of transmission layers and the adjustment factor reported by the RedCap terminal to the base station must not be lower than a specific value, so that the complexity of the RedCap terminal is correspondingly reduced.
However, at different subcarrier spacings, the number of time-frequency resources that can be used by the data channel is different, so that the corresponding peak data rate and maximum TBS are different, and the complexity of the RedCap terminal depends on the highest value thereof. How to further reduce the complexity of the RedCap terminal at different subcarrier spacings is an important issue to be solved in the industry.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
In the 5G NR technology, a terminal device supporting the RedCAP is provided, and the RedCAP terminal has the advantages of low cost, low complexity and the like, and can support the use of the NR technology by a 5G Internet of things terminal with low speed. While the third generation partnership project (3rd Generation Partnership Project,3GPP) specifies that the ratio of the sum of all TBSs of a base station capable of scheduling a RedCap terminal in one slot (slot) to the length of time of that slot is required to be within the constraints of the peak data rate, i.e., the maximum data rate, in Release-17 (Rel-17) version of the standard protocol. Further, the peak data rate supported by the RedCap terminal is associated with a maximum TBS, and reducing the peak data rate may reduce the maximum TBS supported by the RedCap terminal, thereby reducing the complexity of the RedCap terminal.
The huge number of terminals is very complex for the wireless communication system, the complexity of the terminals increases with the increase of the number of terminals, and the overhead related to the data rate control increases with the increase of the number of terminals, so that a great deal of network resources are consumed, and therefore, the network may be congested when the number of terminals is huge.
One possible solution for the complexity reduction of the RedCap terminal in the prior art is to limit the TBS, however when the TBS is further limited, the RedCap terminal complex peak data rate will no longer be applicable as a constraint for the TBS. Yet another possible solution for complexity reduction of the RedCap terminal is to limit the parameters related to reporting by the RedCap terminal to the base station, specifically, in Release-17 version of standard protocol, the product of the modulation order, the number of transmission layers and the adjustment factor required to be reported by the RedCap terminal to the base station must be not lower than 4, and then the minimum limit of the product of the three is reduced, for example, the product is not lower than 4 and not lower than 2, so that the complexity of the RedCap terminal can be reduced.
However, at different subcarrier spacings, i.e. slot (slot) lengths, the number of time-frequency resources that can be used by the data channel is different, and thus the corresponding peak data rate and maximum TBS are different, the complexity of the RedCap terminal depending on the highest value thereof. That is, how to further reduce the complexity of the RedCap terminal at different subcarrier spacings is an important issue to be solved in the industry.
In order to solve the above-mentioned problems, a control method for peak data rate is provided in the present embodiment, which aims to further reduce complexity of the RedCap terminal at different subcarrier intervals. The method for controlling the peak data rate according to the embodiment of the present invention may be applied to an electronic device, including but not limited to a computer, a mobile terminal, etc., and fig. 1 is a flowchart of a method for controlling the peak data rate according to the embodiment of the present invention, as shown in fig. 1, and the method is applied to a base station side, and includes the following steps:
S101, acquiring data rate control parameters reported by a RedCAP terminal. In the embodiment of the invention, the data rate control parameters reported by the RedCap terminal comprise three parameters, namely a modulation order, a transmission layer number and an adjustment factor, wherein the data rate control parameters are determined according to the type of the terminal, subcarrier intervals and the maximum bandwidth supported by the terminal, the difference between adjustment factors corresponding to different subcarrier intervals of the capability reduction terminal is not more than a preset adjustment value, and the adjustment factor is more than 0 and not more than 1. Preferably, the larger the subcarrier interval is, the larger the value of the adjustment factor corresponding to the subcarrier interval is.
It should be noted that the preset control value may be preset, and the value of the preset control value is controlled to be a smaller value, for example, a value between 0.05 and 0.2.
S102, determining the peak data rate supported by the RedCAP terminal, namely the maximum data rate, based on the product of the parameters in the data rate control parameters.
I.e. in the embodiment shown in fig. 1, peak data rate = modulation order x number of transmission layers x adjustment factor. The adjustment factors are determined according to the lengths of the time slots, and the difference value between the adjustment factors corresponding to the lengths of different time slots does not exceed a preset adjustment value, so that the RedCap terminals have approximately equal peak data rates, namely target peak data rates, at different subcarrier intervals, and the peak data rates at any subcarrier interval are prevented from being larger than the target peak data rates, so that the complexity and cost of the RedCap terminals can be further reduced.
And S103, controlling the corresponding RedCAP terminal to perform data transmission based on the peak data rate.
The base station is used as access network equipment, various terminal equipment is accessed into access equipment in a wireless communication system in a wireless mode, and the terminal equipment can be accessed into a core network through the access network equipment, so that data transmission is realized. In the embodiment shown in fig. 1, after obtaining a data rate control parameter reported by a certain RedCap terminal and determining a peak transmission rate of the RedCap terminal, a base station performs data rate control of the RedCap terminal based on the peak transmission rate, adjusts the peak data rate of the RedCap terminal, and further controls the RedCap terminal to perform data transmission.
According to the peak data rate control method provided by the invention, the data rate control parameters are reported by the RedCAP terminal by itself, so that the base station can obtain the peak data rate supported by the RedCAP terminal, therefore, the minimum limit value of the product of the three parameters, namely the modulation order, the transmission layer number and the adjustment factor, is reduced by controlling the data rate control parameters reported by the RedCAP terminal to the base station, the peak data rate of the RedCAP terminal is reduced, the complexity and the cost of the RedCAP terminal are reduced, the consumption of network resources by the cost related to data rate control in a wireless communication system can be saved, and network congestion is avoided. And when the peak data rate is reduced, the difference value between the adjustment factors corresponding to different subcarrier intervals is controlled not to exceed a preset regulation value, so that the RedCAP terminals at different subcarrier intervals are ensured to have approximately equal peak data rates, and the complexity and cost of the terminals are further reduced.
In the embodiment shown in fig. 1, the data rate control parameter reported by the RedCap terminal is obtained, and the transmission of the uplink and downlink data of the terminal is controlled by the unified data rate.
In a communication system, the data transmission direction is divided into uplink and downlink, where uplink refers to data transmission from a terminal to a network side, and downlink refers to data transmission from the network side to the terminal, opposite to uplink. Therefore, in the embodiment shown in fig. 1, the data rate control parameters reported by the RedCap terminal include not only three parameters including modulation order, transmission layer number and adjustment factor, but also uplink coefficient and downlink coefficient, and correspondingly, uplink peak data rate=modulation order×transmission layer number×adjustment factor×uplink coefficient, and downlink peak data rate=modulation order×transmission layer number×adjustment factor×downlink coefficient.
It will be appreciated that the value of the uplink coefficient is smaller than the value of the downlink coefficient, and that the uplink coefficient and the downlink coefficient may be configured and adjusted in advance according to the actual situation.
The method of controlling the peak data rate of the present invention will be described with reference to fig. 2, in which the data rate control parameters of the RedCap terminal are determined by the following steps in the embodiment shown in fig. 1:
A10, determining the length of the time slot based on the subcarrier spacing.
The subcarrier spacing (SubCarrier Spacing, SCS) is a concept of frequency domain resources in a communication system, a subcarrier can be regarded as a small frequency domain resource that can be modulated independently, and is generally larger than a subcarrier, one subcarrier has one or more subcarriers, the subcarrier is a single carrier, for example, in a 100MHz bandwidth, and 15KHz is set as a subcarrier. As the subcarrier spacing increases, the time slot becomes shorter, and the length of the time slot (the duration of the time slot) can be obtained by acquiring the subcarrier spacing, for example, when the subcarrier spacing is 15kHz, the symbol length is 1/15 khz=66.7us, and 14 symbols plus 14 CPs (CP is a cyclic prefix) are added to 1 time slot, and then the length of the time slot is 1ms.
A20, determining the terminal type of the RedCAP terminal and the maximum bandwidth supported by the terminal.
A30, retrieving the data rate control parameters from a preset database based on the terminal type, the time slot length and the maximum bandwidth supported by the terminal.
In the embodiment shown in fig. 1, the related information of the data rate control parameter of the RedCap terminal may correspond to the terminal type, the length of the time slot, and the maximum bandwidth supported by the terminal, and then the related information of the corresponding data rate control parameter is stored in a database, that is, a preset database. And when the data of one of the RedCAP terminals needs to be transmitted, specific parameters in the corresponding data rate control parameters are called from a preset database according to parameters (including the terminal type, the time slot length and the maximum bandwidth supported by the terminal) related to the RedCAP terminal, and then the data rate control parameters reported to the base station by the RedCAP terminal are called from the preset database.
Specific examples are: when the RedCap terminal is a terminal of a first type and the maximum bandwidth supported by the terminal is the first bandwidth, the information stored in the pre-selected database is: the modulation order value is 1, the transmission layer number value is 2, the adjustment factor value is 0.9 for the subcarrier interval of 15 KHz, and the adjustment factor value is 0.95 for the subcarrier interval of 30 KHz; when the RedCap terminal is a second type terminal and the maximum bandwidth supported by the terminal is a second bandwidth, the information stored in the pre-selected database is: the modulation order value is 1, the transmission layer number value is 1, the adjustment factor value is 0.3 for the subcarrier interval of 15 KHz, and the adjustment factor value is 0.35 for the subcarrier interval of 30 KHz; when the RedCap terminal is a third type terminal and the maximum bandwidth supported by the terminal is a second bandwidth, the information stored in the pre-selected database is: the modulation order value is 1, the number of transmission layers is 1, the adjustment factor value is 0.6 for the subcarrier interval of 15 KHz, and the adjustment factor value is 0.65 for the subcarrier interval of 30 KHz. The difference between the adjustment factors corresponding to the subcarrier intervals of 15 KHz and 30KHz of the RedCAP terminal is 0.05, and the difference is within the value range of the preset regulation and control value.
In the existing 5G NR standard protocol, the product of the modulation order, the transmission layer number and the regulating factor of the RedCAP terminal is not lower than 4. In the embodiment shown in fig. 1, when the RedCap terminal is the terminal of the first type and the maximum bandwidth supported by the terminal is the first bandwidth, the minimum value limitation of the product of the three is released to be not less than 1.8 or 1.9, so that the complexity of the terminal can be obviously reduced. And the product of the three is not lower than 1.8 at 15KHz subcarrier spacing and not lower than 1.9 at 30KHz subcarrier spacing, so that the RedCAP terminal can support approximately equal minimum peak data rate of about 6Mbps at 15KHz and 30KHz subcarrier spacing. On the other hand, in the existing 5G NR standard protocol, the maximum TBS of a system information block (System Information Block, SIB) is 2976 bits, and the peak data rate of a corresponding terminal is about 6Mbps at a 30KHz carrier interval, so that the minimum support of the RedCAP terminal is 6Mbps, and the SIB can be ensured to be received under the conditions of 15KHz and 30KHz subcarrier intervals; when the RedCap terminal is the terminal of the second type and the maximum bandwidth supported by the terminal is the second bandwidth, the product of the three is not lower than 0.3 or 0.35, the RedCap terminal can be ensured to have a peak data rate of 1Mbps, and when the RedCap terminal is the terminal of the third type and the maximum bandwidth supported by the terminal is the second bandwidth, the product of the three is not lower than 0.6 or 0.65, the RedCap terminal can be ensured to have a peak data rate of 2 Mbps.
By querying a preset storage library, the related information of the data rate control parameters corresponding to each RedCAP terminal can be obtained according to the parameters of the RedCAP terminal.

A second determining module 405, configured to determine whether the group peak data rate supported by the group RedCap terminal meets a processing requirement of the group predicted data throughput. I.e. whether the group peak data rate supported by the group RedCap terminal can be transmitted (processed) in the current time slot to complete the group predicted data throughput.
A fourth control module 406, configured to control the corresponding group RedCap terminal to perform data transmission based on the group peak data rate if the processing requirement of the group predicted data throughput is met; and if the processing requirement of the group predicted data processing capacity is not met, controlling the corresponding group RedCap terminal to perform data transmission based on the group peak data rate and a preset regulation and control coefficient. In the embodiment of the invention, the preset regulation and control coefficient is a value interval, and the preset regulation and control coefficient is larger than 1.
The peak data rate control device provided by the invention automatically reports the data rate control parameters through the group RedCap terminal, so that the base station can obtain the peak data rate supported by the group RedCap terminal, therefore, the minimum limit value of the product of the three parameters, namely the modulation order, the transmission layer number and the adjustment factor, is reduced through controlling the data rate control parameters reported by the group RedCap terminal to the base station, thereby reducing the peak data rate of the group RedCap terminal, further reducing the complexity and cost of the group RedCap terminal, saving the cost related to data rate control in a wireless communication system on network resources, avoiding network congestion, and improving the efficiency of data control by simultaneously controlling all the RedCap terminals in the group so that the RedCap terminal in the group can better perform data transmission, further avoiding network congestion and reducing the complexity of the terminal. The method comprises the steps of judging that the peak data rate of a group can meet the processing requirement of a current time slot by predicting the data quantity required to be transmitted by the RedCAP terminal of the group in the current time slot, regulating and controlling the peak data rate of the group by a preset regulating and controlling coefficient, ensuring that the RedCAP terminal of the group meets the corresponding task requirement on the premise of reducing the peak data rate of the group, and reasonably reducing the complexity of the terminal. And when the peak data rate is reduced, the difference value between the adjustment factors corresponding to different subcarrier intervals is controlled not to exceed a preset regulation value, so that the RedCAP terminals at different subcarrier intervals are ensured to have approximately equal peak data rates, and the complexity and cost of the terminals are further reduced.
