The modulation power distribution method provided by the embodiment of the invention can be applied to a CU (Centralized Unit) and terminal equipment. In the 5G (5th generation mobile communication technology), each base station has a set of DUs (Distributed units), and a plurality of base stations share a set of CUs.
As shown in fig. 1, an embodiment of the present invention provides a modulation power allocation method, which when applied to a CU, may include the following steps:
s11, responding to the wireless reference information reported by each terminal device to be allocated with modulation power, and recording a first corresponding relation between the terminal identification and the wireless reference information.
The "terminal devices to which modulation power is to be allocated" may be terminal devices that report priority information to the CU and are all connected to the same base station; the NR measurement request is used to request each terminal device to be allocated with modulation power to report radio reference information.
The CU may record a first correspondence between the terminal identifier and the wireless reference information based on the received wireless reference information reported by each terminal device, so as to query the wireless reference information corresponding to each terminal device.
And S12, distributing first modulation power for each terminal device according to the second corresponding relation and the first corresponding relation between the locally stored terminal identification and the priority information.
The "second correspondence between the terminal identifier and the priority information" may be pre-established and stored by the CU, and the "priority information" may be determined by the terminal device according to the slice service duration information, the slice number information, and the remaining power information of the terminal device, and then reported to the CU.
The CU may allocate the first modulation power to each terminal device according to the second correspondence between the locally stored terminal identifier and the priority information and the first correspondence between the terminal identifier and the wireless reference information.
As can be seen from the foregoing steps S11-S13, in the modulation power allocation method provided in the embodiment of the present invention, in response to receiving the wireless reference information reported by each terminal device to which modulation power is to be allocated, a first correspondence between the terminal identifier and the wireless reference information is recorded, and the first modulation power is allocated to each terminal device according to a second correspondence and the first correspondence between the locally stored terminal identifier and the priority information. The wireless reference information reported by the terminal equipment can reflect the requirement of the terminal equipment on actual power consumption control to a certain extent, the priority information of the terminal equipment is determined and reported by the terminal equipment according to the slice service time length information, the slice number information and the residual electric quantity information, the CU distributes first modulation power for each terminal equipment according to the priority information of each terminal equipment to be distributed with modulation power and the wireless reference information, the requirement of the terminal equipment on actual power consumption control, the slice number of slices linked by the terminal equipment and the slice service time length required by the terminal equipment are considered, the power consumption requirement of the terminal equipment can be met, and the condition that the power consumption required by the terminal equipment is smaller than the actual power consumption can be avoided.
In some embodiments, the wireless Reference information includes DMRS (Demodulation Reference Signal) and modulated carrier number information.
The "DMRS and modulated carrier quantity information" may be reported by each terminal device based on an NR measurement request sent by the CU, or may be reported by each terminal device through a Physical Uplink Control Channel (PUCCH).
As shown in fig. 2, in some embodiments, the allocating a first modulation power to each terminal device according to the second corresponding relationship and the first corresponding relationship between the locally stored terminal identifier and the priority information (i.e., S13) may include:
and S131, dividing the terminal devices with the same priority information into the same group according to a second corresponding relation between the terminal identification and the priority information, and distributing second modulation power to each group according to the preset total power and the total number of the terminal devices in each group.
The "second modulation power" may be the sum of the power that can be allocated to all terminal devices in the group.
The CU may divide the terminal devices having the same priority information into the same group according to the second correspondence between the locally stored terminal identifier and the priority information, and thus, each terminal device is divided into a plurality of groups according to the priority information. After grouping, the CU may allocate a second modulation power to each group according to a preset total base station transmission power K and the total number of terminal devices in each group.
For example, the CU may divide terminal devices with priority information of I level into group 1, divide terminal devices with priority information of II level into group 2, and divide terminal devices with priority information of III level into group 3 … … assuming that each terminal device is divided into P groups, the CU may also divide second modulation powers of P levels according to the total base station transmission power K: k1, K2, K3 … … Kp, and the sum of the P classes of power is K: k1+ K2+ K3+ … … Kp ═ K; the CU may also determine specific values of K1, K2, K3 … … Kp according to the total number of the terminal devices in each group: k1: k2: k3: … … Kp ═ total number of end devices in group 1 ]: [ total number of terminal devices in group 2 ]: [ total number of terminal devices in group 3 ]: … … [ total number of end devices in the P-th group ]. CU may assign a second modulation power K1 to group 1, a second modulation power K2 to group 2, and a second modulation power K3 … … to group 3 and a second modulation power Kp to group P.
It should be noted that P is only a positive integer, and the value of P is not specifically limited in the embodiment of the present invention.
And S132, classifying the terminal equipment in the group according to the DMRS and the modulation carrier number information corresponding to the terminal equipment in the group and distributing third modulation power to each class in the group according to the second modulation power distributed by the group.
Wherein, the "third modulation power" may be the sum of the power that can be allocated to all terminal devices in the class.
After grouping and allocating the second modulation power to each group, the CU may also classify each terminal device in each group. Specifically, for each group, the CU determines DMRS and modulated carrier number information corresponding to each terminal device in the group according to the recorded first correspondence between the terminal identifier and the DMRS and modulated carrier number information, classifies each terminal device in the group according to the DMRS and modulated carrier number information corresponding to each terminal device in the group, and allocates third modulation power to each class in the group according to the second modulation power allocated by the group.
And S133, for each category, allocating first modulation power to each terminal device in the category according to the total number of the terminal devices in the category and the third modulation power allocated by the category.
For each category, the CU may allocate, to each terminal device in the category, the first modulation power according to the total number of terminal devices in the category and the third modulation power allocated by the category. Specifically, if the total number of the terminal devices in the category is X, and the third modulation power allocated to the category is Y, then modulation power Y/X may be allocated to each terminal device in the category.
After allocating the first modulation power to each terminal device in each category in each group, the CU may further feed back, to each terminal device, the allocation result of the corresponding first modulation power.
As shown in fig. 3, in some embodiments, the classifying, according to the DMRS and the modulated carrier number information corresponding to each terminal device in the group, and allocating, according to the second modulation power allocated by the group, third modulation power to each class in the group (i.e., as described in S132), may include the following steps:
and S1321, determining the distribution coefficient sequence of each terminal device in the group according to the DMRS and the modulation carrier number information corresponding to each terminal device in the group.
For each group, a CU may first determine a power spectrum p (d) of a DMRS corresponding to each terminal device in the group according to the DMRS corresponding to each terminal device in the group, where d is a time-domain sampling point (a discrete sequence X [ k ] is obtained by extracting a sampling point from a continuous-time signal X (t)), and then determine an allocation coefficient sequence m (d) of each terminal device in the group according to p (d) and modulation carrier number information. For example, the CU may determine the distribution coefficient sequence m (d) of each terminal device according to the following formula:
The distribution coefficient sequence m (d) of the terminal device can reflect the DMRS quality of the terminal device to some extent, and the smaller the value in m (d), the worse the DMRS quality of the terminal device.
S1322, classifying the terminal devices in the group according to the distribution coefficient sequence of each terminal device in the group and a preset threshold interval, and calculating an average value of the distribution coefficient sequence of each class.
Here, the "average value of the distribution coefficient sequence for each class" may be an average value of the distribution coefficient sequences of all terminal devices in each class.
For each group, the CU may classify the terminal devices in the group whose distribution coefficient sequence is in the interval [ threshold 1, threshold 2] into the 1 st category, classify the terminal devices whose distribution coefficient sequence is in the interval [ threshold 3, threshold 4] into the 2 nd category, classify the terminal devices whose distribution coefficient sequence is in the interval [ threshold 5, threshold 6] into the 3 rd category … … intervals [ threshold 1, threshold 2], [ threshold 3, threshold 4], [ threshold 5, threshold 6] which are all preset threshold intervals, may be determined according to historical data or determined by iterative optimization algorithm, the threshold 1 needs to be smaller than the threshold 3, the threshold 3 needs to be smaller than the threshold 5, the threshold 2 needs to be smaller than the threshold 4, and the threshold 4 needs to be smaller than the threshold 6 … …, but the embodiment of the present invention does not make special restrictions on the size relationship between the threshold 2 and the threshold 3 and the size relationship between the threshold 4 and the threshold 5. That is, a plurality of threshold intervals that are preset exhibit an increasing trend, but two threshold intervals that are consecutive may intersect.
After dividing each terminal device in the group into a plurality of categories, the CU may further calculate, for each category, an average value of the distribution coefficient sequences of all terminal devices in the category as an average value of the distribution coefficient sequences of the category.
And S1323, distributing third modulation power for each class in the group according to the second modulation power distributed by the group and the average value of the distribution coefficient sequences of each class in the group.
Specifically, for each group, assuming that each terminal device in the group is divided into Q classes, the CU may also divide Q levels of third modulation power according to the second modulation power Km allocated by the group: h1, H2, H3 … … Hq, and the sum of the Q levels of power is Km: h1+ H2+ H3+ … … Hq ═ Km; the CU may also determine specific values of H1, H2, and H3 … … Hq according to an average value of the distribution coefficient sequences of each category in the group: h1: h2: h3: … … Hq ═ average of the distribution coefficient sequences of the Q-th class ]: [ average value of distribution coefficient series of the (Q-1) th class ]: [ average value of distribution coefficient series of the (Q-3) th class ]: … … [ mean value of the distribution coefficient sequence of category 1 ]. The CU may assign a third modulation power H1 for category 1, H2 for category 2, H3 … … for category 3, and Hq for category Q.
It should be noted that Q is only required to be a positive integer, and the value of Q is not specifically limited in the embodiment of the present invention.
For each group, the CU classifies each terminal device in the group according to a threshold interval in which its distribution coefficient sequence is located, since a plurality of preset threshold intervals are increasing, an average value of the distribution coefficient sequences of each class is usually increasing from the 1 st class to the Q th class, and the CU allocates a third modulation power to each class according to the average value of the distribution coefficient sequences of each class, and then the third modulation power allocated to each class is decreasing from the 1 st class to the Q th class. In the foregoing, the smaller the value in the allocation coefficient sequence m (d) of the terminal device is, the worse the DMRS quality of the terminal device is, and with the modulation power allocation method provided in the embodiment of the present invention, the smaller the average value of the allocation coefficient sequence is, the larger the allocated third modulation power is, the higher the DMRS quality of the terminal device in the category can be effectively improved.
As shown in fig. 4, in some embodiments, after allocating the first modulation power to each terminal device according to the second corresponding relationship and the first corresponding relationship between the locally stored terminal identifier and the priority information (i.e., S13), the modulation power allocation method may further include the following steps:
and S14, under the condition that the peak-to-average ratio of the terminal equipment exceeds the preset threshold, determining fourth modulation power according to the first modulation power of the terminal equipment of which the peak-to-average ratio exceeds the preset threshold, and distributing the fourth modulation power for the terminal equipment of which the peak-to-average ratio exceeds the preset threshold.
Within a certain time after the first modulation power is allocated to each terminal device, the CU may also monitor whether the peak-to-average power ratio of each terminal device exceeds a preset threshold, and when the peak-to-average power ratio of a certain terminal device exceeds the preset threshold, it is described that the first modulation power allocated to the terminal device may cause a high peak-to-average power ratio, which may further affect the performance of the communication system, and at this time, the first modulation power needs to be adjusted.
As shown in fig. 5, in some embodiments, the modulation power allocation method may further include the following steps:
and S21, responding to the slicing request sent by the terminal equipment, and acquiring the terminal identification and the priority information carried in the slicing request.
In the embodiment of the present invention, when a terminal device initiates a slicing Request to a base station, besides reporting a Registration application Registration Request to the base station, priority information needs to be carried in the slicing Request, where the priority information is displayed by identification bits, such as I, II, and III, and when the base station receives the slicing Request sent by the terminal device, a CU may obtain a terminal identification and priority information carried in the slicing Request.
And S22, establishing and storing a second corresponding relation between the terminal identification carried in the slicing request and the priority information.
The CU may establish a second correspondence between the terminal identification and the priority information carried in the request for slicing and store the second correspondence locally.
As shown in fig. 6, an embodiment of the present invention provides a modulation power allocation method, which when applied to a terminal device, may include the following steps:
s31, responding to the received NR measurement request sent by the CU, reporting the wireless reference information to the CU, so that the CU can record a first corresponding relation between the terminal identifier and the wireless reference information, and distributing first modulation power for each terminal device according to a second corresponding relation and the first corresponding relation between the terminal identifier and the priority information stored locally by the CU.
The NR measurement request is used to request the terminal device to report the wireless reference information. The terminal equipment can report the wireless reference information to the CU through the PUCCH. The wireless reference information may include DMRS and modulation carrier number information.
As shown in fig. 7, in some embodiments, before reporting the radio reference information to the CU (i.e., S31) in response to receiving a new radio NR measurement request sent by a central unit CU, the terminal device-side modulation power allocation method may further include the steps of:
and S30', determining the priority information of the terminal device according to the slice service duration information, the slice number information and the residual capacity information of the terminal device.
The terminal device may first obtain the slicing service duration information of the terminal device. Specifically, a User may be requested to provide and receive slice service duration information input by the User through a User Interface (UI), for example, duration information for a User planning to use an APP (Application); the slicing service duration information may also be obtained according to the behavior habit of the user, for example, rough slicing service duration information about time, location, and the like is obtained according to the historical data of the slicing service used by the user: the service time of the map navigation slicing service of the non-resident place is about 40 minutes, the service time of the automatic driving slicing service of 18-19 points in Beijing time is about 1 hour, the service time of the video service slicing service of 21-22 points in Beijing time is about 1 hour, and the like.
After the slicing service duration information of the terminal device is obtained, the terminal device can measure the slicing service duration information, the slicing number information and the residual electric quantity information of the terminal device through a specific rule so as to determine the priority information of the terminal device. For example, if the remaining power information is less than a threshold value (I), the slice number information is greater than a threshold value (ii), and the slice service duration information is greater than a threshold value (iii), it indicates that the terminal device is in a state of fast power consumption and has a high demand for reducing power consumption, and at this time, the priority information may be determined as level I; if the residual electric quantity information is less than the threshold value, the slice number information is greater than the threshold value, and the slice service duration information is greater than the threshold value, it indicates that the terminal device has a high demand for reducing power consumption, at this time, the priority information may be determined to be level II … …, and the priority information of the terminal device may be determined according to the slice service duration information, the slice number information, and the size relationship between the residual electric quantity information and the preset corresponding threshold value of the terminal device.
It should be noted that, the above manner of measuring the slice service duration information, the slice number information, and the remaining power information by the specific rule to determine the priority information may be predetermined by the CU and the terminal device.
And S30, sending the slicing request carrying the terminal identifier of the terminal equipment and the priority information to the CU, so that the CU can establish and store a second corresponding relation between the terminal identifier carried in the slicing request and the priority information.
When the terminal equipment initiates a slicing request to the base station, the priority information of the terminal equipment can be reported together for the CU to record the priority information of the terminal equipment, so that the CU can distribute first modulation power for the terminal equipment according to the priority information and the wireless reference information reported by the terminal equipment.
