Detailed Description
In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments of the present disclosure. However, it will be understood by those skilled in the art that the present disclosure may be practiced without these specific details.
In the description of the present disclosure, the above, below, inside, at least, etc. are understood to include the instant numbers. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
The disclosed embodiments provide an input power conversion method 100 for a base station, which is described in detail below with reference to fig. 1-4 for ease of understanding.
As shown in fig. 1, a flowchart of an input power conversion method 100 for a base station according to the present embodiment is provided, where the method 100 includes step S101, step S102, step S1021, and step S103; or step S101, step S102, step S1022 and step S103.
Step S101, acquiring an actual power range of input power, and determining the maximum value of the actual power range as the maximum input power;
specifically, as shown in fig. 2, a schematic structural diagram of a base station provided for the related art is provided, where the base station includes a BBU, a RHUB (remote radio unit hub), and an RRU. According to an OSI (Open System Interconnection Reference Model) protocol, the BBU may include a data link layer (L2 layer for short), a network layer (L3 layer for short), and a HighPhy part of a physical layer, and the RHUB includes a LowPhy part of the physical layer, where the LowPhy part of the physical layer is responsible for converting a frequency domain signal into a time domain signal. The BBU carries out floating point conversion in the HighPhy part, the output floating point value data is transmitted to RHUB after first compression (frequency domain compression), and the data output by RHUB is transmitted to the RRU after second compression (time domain compression). For the related art, on one hand, when the floating-point conversion is performed, the conversion precision is determined according to the theoretical maximum input power, that is, under the condition that the bit width is not changed, the number of integer digits representing the size range of the floating-point value is fixed, and therefore, the number of decimal digits representing the conversion precision is also fixed, and therefore, the conversion precision is not highest for input powers in different ranges; on the other hand, the compression process of the data also causes the loss of precision, and therefore, the data is further caused to lose the precision in the process of transferring the data from the BBU to the RRU. If the loss of precision is too large, the EVM (Error Vector Magnitude) of the base station is affected, and thus the Error rate is increased. Therefore, it is important to dynamically adjust the conversion accuracy for different ranges of input power, so as to obtain a floating point value with higher accuracy as much as possible while satisfying the floating point conversion for all input powers within the range.
The inventor has found through research that the data link layer and the network layer of the BBU are responsible for the protocol stack, and therefore, as shown in fig. 3, the present embodiment can obtain the actual power range of the input power Npower by the capability authentication between the HighPhy part and the protocol stacks related to the data link layer and the network layer. For example, the obtained input power Npower is the input power configured during downlink initialization, and as shown in table 1, the following 5 input power Npower types may be included according to the modulation scheme on the RE (Resource Element): PDCCH _ QPSK, PDSCH _16QAM, PDSCH _64QAM, and PDSCH _256QAM, wherein PDCCH (physical Downlink Control channel) refers to physical Downlink Control channel, PDSCH (physical Downlink Shared channel) refers to physical Downlink Shared channel, QPSK (quadrature Phase Shift keying) refers to quadrature Phase Shift keying modulation, and QAM (quadrature Amplitude modulation) refers to quadrature Amplitude modulation, and the 5 types of input power all have corresponding power Control dynamic ranges, and as an example, the power Control dynamic ranges of the 5 types of input power are specifically shown in table 1.
TABLE 1 RE Power control dynamic Range supported by the System
It is understood that the actual power range of the input power Npower referred to in step S101 is determined by integrating the above-mentioned 5 types of input power control dynamic ranges. Thus, for example, from Table 1, the actual power range of the input power Npower may be determined to be [ -6,3], and the maximum input power Npower0 may be 3 dB.
Step S102, judging whether all actual values of the power ratio under preset configuration can be obtained or not, and determining the minimum value in all the actual values as the actual minimum value of the power ratio;
specifically, the preset configuration may include a first parameter and a second parameter. The first parameter is a parameter for characterizing which Code Division Multiplexing (CDM) REs cannot multiplex data currently, and may take three values, i.e., 1, 2, and 3. The values have the following meanings: a value of 1 indicates that REs of the current CDM group 0 cannot multiplex data; a value of 2 indicates that neither RE of the current CDM group 0 nor CDM group 1 can multiplex data; a value of 3 indicates that none of the current CDM group 0, CDM group 1, and CDM group 2 can multiplex data. The second parameter is a parameter for characterizing a demodulation DMRS (demodulation Reference Signal) configuration type, and for example, the 3rd Generation Partnership Project (3 GPP) protocol specifies two configuration types for PDSCH DMRS: type 1 and type 2. For example, as shown in table 2, the configuration is a list of values of the acquired power ratio when the preset configuration is "the first parameter takes a value of" 3 ", and the second parameter is" two configuration types including type 1 and type 2 ".
Table 2 power ratio obtained under preset configuration
Note that, as shown in table 2, if: when the value of the first parameter is 1, the values of the power ratio ratios corresponding to the DMRS configuration type 1 and the DMRS configuration type 2 can be respectively obtained; when the value of the first parameter is 2, the values of the power ratio ratios corresponding to the DMRS configuration type 1 and the DMRS configuration type 2 can be respectively obtained; when the value of the first parameter is 3, the value of the power ratio corresponding to the DMRS configuration type 2 can be obtained. It is considered that all actual values of the power ratio ratios in the preset configuration "the first parameter takes a value of '3', the second parameter 'includes both the type 1 and the type 2 configuration types'", and the minimum value "-4.77" of all the actual values "" 0 "," -3 ", and" -4.77 "" is referred to as the actual minimum value of the power ratio.
It is to be understood that the enumerated preset configuration is that "the first parameter takes the value of '3', the second parameter is 'two configuration types including type 1 and type 2'," is merely taken as an example, and for other preset configurations, it is determined whether all actual values of the power ratio under the preset configuration can be obtained and belong to the same concept as the enumerated preset configuration, that is, it is determined according to the relevant communication protocol that all values of the power ratio need to be obtained, and it is determined whether the value of the power ratio can be actually obtained, if so, it is considered that all actual values of the power ratio under the preset configuration can be obtained, otherwise, it is considered that all actual values of the power ratio under the preset configuration cannot be obtained.
If the determination result in the step S102 indicates that all actual values of the power ratios in the preset configuration can be obtained, then step S1021 is executed: determining the actual maximum conversion precision of the floating point conversion of all the input power in the actual power range according to the maximum input power and the actual minimum value of the power ratio;
specifically, as an example, according to the 5G (5th Generation Mobile Communication Technology, fifth Generation Mobile Communication) protocol, the formula of the floating point conversion is as follows:
f(Npower)＝floatA(10(Npower-ratio0)/20)； (1)
where Npower represents the input power, ratio0 represents the actual minimum of the power ratio, 10(Npower-ratio0)/20Representing an arithmetic floating-point value y, i.e. y 10(Npower-ratio0)/20The floating-point conversion precision is denoted by a, (y) floataa, (y) and (f), (Npower) denote the floating-point value (referred to as the actual floating-point value for short) actually obtained after the input power Npower is subjected to floating-point conversion, and the actual floating-point value can be regarded as the representation of the arithmetic floating-point value y on the conversion precision a.
According to the machine algorithm rule, taking binary data with a bit width of 16 bits and a sign bit of 1bit as an example, as shown in table 3, a corresponding relationship between an actual floating point value f (npower) and a conversion precision a is shown.
TABLE 3 correspondence between actual floating-point values f (Npower) and conversion precisions A
It is understood that, in the floating-point conversion, for the conversion between the arithmetic floating-point value y and the actual floating-point value f (npower), the actual floating-point value f (npower) is expected to have higher conversion precision on the basis of satisfying the size of the arithmetic floating-point value y. Mathematical expression of the arithmetic floating-point value y 10(Npower-ratio0)/20It can be seen that the magnitude of y is proportional to the value of Npower, so that when the input power Npower within a certain range takes the maximum value Npower0, the corresponding arithmetic floating point value y is also maximum, and thus the rootAccording to the maximum arithmetic floating point value ymaxSelecting the maximum conversion accuracy Amax. It is readily understood that this maximum conversion accuracy AmaxFloating point conversions for other input powers Npower in the range are also satisfied.
In summary, according to the maximum input power Npower0 and the power ratio actual minimum ratio0, the maximum conversion precision a of floating-point conversion satisfying all the input powers Npower in the actual power range can be determinedmax。Illustratively, if the actual power range of the input power Npower obtained in step S101 is [ -6,12 [ ]]If the maximum input power Npower0 is 12, the power obtained in step S102 is 0 compared to the actual minimum value ratio0, and the corresponding arithmetic floating point value y is 3.9810717055349722, it can be seen from table 3 that the maximum conversion accuracy (a) is 13 bits at the maximum on the basis of the size of y, and thus the maximum conversion accuracy (a) is obtainedmax13 bits) satisfies the actual power range of [ -6,12 []Floating point conversion of all input powers Npower. If the actual power range of the input power Npower obtained in step S101 is [ -6,13 [)]If the maximum input power Npower0 is 13, the power obtained in step S102 is 0 compared to the actual minimum value ratio0, and the corresponding arithmetic floating point value y is 4.466835921509632, it can be seen from table 3 that the maximum conversion accuracy (a) is 12 bits at the maximum on the basis of the size of y, and thus the maximum conversion accuracy (a) is obtainedmax12 bits) satisfies the actual power range of [ -6,13 []Floating point conversion of all input powers Npower.
It should be noted that the maximum conversion accuracy a determined based on the maximum input power and the actual minimum value of the power ratio is described abovemaxReferred to as the actual maximum conversion accuracy.
Step S103: and obtaining a floating point value corresponding to each input power according to the actual maximum conversion precision and the actual minimum value of the power ratio.
Specifically, through the above steps S101, S102, and S1021, the maximum input power Npower0, the power ratio actual minimum ratio0, and the actual maximum conversion accuracy a determined based on the actual power range of the input power and the power ratio actual minimum ratio0 can be obtainedmax. Therefore, for each inputThe formula for the floating point conversion of the input power Npower can be determined as follows:
f(Npower)＝floatAmax(10(Npower-ratio0)/20)； (2)
therefore, a floating point value corresponding to each input power Npower in the first set may be calculated according to the above expression.
Preferably, in order to satisfy the data processing structure of the hardware level, the floating point value may be further subjected to fixed point conversion to obtain a fixed point value. Specifically, the formula of the fixed-point conversion is as follows:
Q(Npower)＝fix(f(Npower)*2A)；
where a denotes conversion accuracy, and fix (x) denotes rounding-down, it is understood that in the present embodiment, a ═ amax。
Preferably, when the floating-point value Npower is converted into the fixed-point value q (Npower), in order to reduce the truncation error, 0.5, i.e. q (Npower) fix (f (Npower)) 2, may be added before roundingA+0.5)。
The embodiment has the beneficial effect that by dynamically adjusting the conversion precision for the input power in different ranges, a floating point value with higher precision can be obtained while the floating point conversion is performed on all the input power in the range.
The inventor finds that the occurrence of the input power Npower is repetitive, that is, different input powers Npower may occur once or twice or more, and if the calculation is performed by the above formula each time, the calculation amount is greatly increased, and the time of the floating point conversion is also increased.
Preferably, in order to reduce the operation overhead and save the time of floating point conversion, the floating point conversion value may be determined by looking up the mapping relationship. That is, the step S103 "obtaining a floating point value corresponding to each input power according to the actual maximum conversion precision and the actual minimum value of the power ratio" specifically includes: determining a target mapping relation according to the actual maximum conversion precision and the actual minimum value of the power ratio, and determining a floating point value corresponding to each input power according to the target mapping relation; wherein the target mapping relation is a power-floating point value mapping relation corresponding to each input power, and the power-floating point value mapping relation is established according to a preset power range and a power ratio candidate minimum value of the input power.
Specifically, as shown in fig. 4, the step of establishing the "power-floating point value mapping relationship" according to the preset power range of the input power and the power ratio candidate minimum value includes steps S1001 to S1002.
Step S1001: obtaining at least two power ratio candidate minimum values, and determining candidate maximum conversion precision which corresponds to the power ratio candidate minimum values and meets the requirement of floating point conversion of all the input power in a preset power range according to a preset power range of the input power and each power ratio candidate minimum value;
specifically, a candidate minimum value of the power ratio may be determined according to the communication protocol. As an example, according to the 5G protocol, the power ratio has three candidate minimum values of ratio10, 0, -3, -4.77, respectively. The preset power range includes a maximum preset input power Npower10 and a minimum preset input power Npower20, wherein the candidate maximum conversion precision B can be understood from the above embodimentsmaxIs only associated with the maximum default input power Npower10, the minimum default input power Npower20 can be default according to the actual situation, for example, the minimum default input power Npower20 is-21 dB, the default power range is [ -21, Npower10]。
According to the maximum preset input power Npower10 and the minimum candidate ratio10 of each power ratio, in combination with formula (1) and table 3, the candidate maximum conversion precision B of floating-point conversion of all the input powers Npower satisfying the preset power range corresponding to each minimum candidate ratio10 of the power ratio can be determinedmax. Illustratively, if the predetermined power range is [ -21,6 [ ]]The power ratio candidate minimum value ratio10 is 0, and the corresponding candidate maximum conversion accuracy B can be determined according to equation (1) and table 3maxIs 14 bits; if the predetermined power range is [ -21,6 [)]The power ratio candidate minimum value ratio10 is-3, and the corresponding candidate maximum conversion accuracy B can be determined according to the formula (1) and Table 3maxIs 13 bits; if the predetermined power range is [ -21,6 [)]The power ratio candidate minimum ratio10 is-4.77, and the corresponding candidate maximum conversion accuracy B can be determined according to equation (1) and Table 3maxIs 13 bits.
Further, a candidate maximum conversion precision B may be determinedmaxCorresponding to the power ratio candidate minimum ratio10 and the maximum preset input power Npower10, as shown in table 4.
Table 4: maximum conversion accuracy BmaxList of relationships with the power ratio candidate minimum ratio10 and the maximum preset input power Npower10
Step S1002: establishing a power-floating point value mapping relation corresponding to the candidate maximum conversion precision and the power ratio candidate minimum value according to each power ratio candidate minimum value and the candidate maximum conversion precision corresponding to the power ratio candidate minimum value;
specifically, the power-floating point value mapping relationship includes an input power-floating point value mapping relationship, and more specifically, the mapping relationship may be a relationship list, and a group of relationship lists respectively corresponds to a candidate maximum conversion precision BmaxAnd a power ratio candidate minimum ratio 10. The relationship list reflects a correspondence between a floating point value f (Npower) and an input power Npower within the preset power range. Specifically, the corresponding relationship between the floating point value f (Npower) and the input power Npower in the relationship list is determined according to formula (1) (where a is B)max)。
Preferably, in order to satisfy the data processing structure of the hardware level, the floating point value in the relationship list is further subjected to fixed point conversion to obtain a corresponding fixed point value. Specifically, the formula of the fixed-point conversion is as follows:
Q(Npower)＝fix(f(Npower)*2A)；
where a denotes conversion accuracy and fix (x) denotes rounding-down, it is understood that in the present embodiment, a ═ B denotesmax. Thus, input power-fixed point can be obtainedAnd (4) value mapping relation.

Preferably, for the "determining a target mapping relationship according to the actual maximum conversion precision and the actual minimum value of the power ratio, and determining a floating point value corresponding to each input power according to the target mapping relationship", the method specifically further includes: comparing the actual maximum conversion precision with the candidate maximum conversion precision, comparing the power ratio actual minimum value with the power ratio candidate minimum value, determining the candidate maximum conversion precision which are all the same and the power-floating point value mapping relation corresponding to the power ratio candidate minimum value as a target mapping relation, and determining the floating point value corresponding to each input power according to the target mapping relation. Illustratively, if the actual power range obtained is [ -6,13 [ ]]Then the actual maximum conversion accuracy A is calculatedmaxWhen the obtained power ratio actual minimum ratio0 is 0, table 5.1 is determined as the target relationship list by comparing the relationship lists. The converted floating point value corresponding to each input power Npower is determined by means of table look-up (table 5.1).
The embodiment has the advantages that the operation cost of the processor can be greatly reduced and the time for floating point conversion can be saved by firstly establishing a relation list of the floating point value f (Npower) and the input power Npower or a relation list of the fixed point value Q (Npower) and the input power Npower and then determining the converted floating point value or fixed point value corresponding to each input power Npower in a comparison and table look-up manner.
Based on this, the inventor further studies and finds that, in the relationship lists between the floating point values f (Npower) and the input power Npower, any two groups of relationship lists (i.e. B) having the same candidate maximum conversion precision are selectedmax2＝Bmax1) The following rules are provided:
f2(Npower)＝f1(Npower+ratio102-ratio101)；
wherein, Bmax2Representing a second set of floating-point values f2(Npower) maximum conversion precision candidate corresponding to the relation list of input power Npower, Bmax1Representing a first set of floating-point values f1(Npower) maximum conversion precision candidate corresponding to the list of relationships of input power Npower, ratio102 refers to the second set of floating point values f2(Npower) and input power Npower, ratio101 refers to the first set of floating point values f1(Npower) minimum power ratio candidate value corresponding to the relation list of input power Npower, "f2(Npower)＝f1(Npower + ratio101-ratio102) "represents the first set of floating-point values f1The floating point value f corresponding to the input power of 'Npower + ratio101-ratio 102' in the relation list of (Npower) and input power Npower1(Npower + ratio102-ratio101) with a second set of floating point values f2Floating point value f corresponding to the input power of Npower in the relation list of (Npower) and input power Npower2(Npower) are equal. Equal floating point values are used for multiplexing in any two sets of relation lists with the same candidate maximum conversion precision.
The embodiment has the advantage that the floating point value data which are equal in any two groups of relation lists can be multiplexed when the relation lists are formulated, so that the calculation amount of the processor is further reduced.
In view of the above, since the input power Npower takes an integer value, and when the power ratio candidate minimum value ratio10 takes a value of-3 or 0 (an integer value), the demodulation reference power EPRE is made equal to Npower-ratio10, and for the demodulation reference power EPRE, the EPRE also takes an integer value.When the power ratio candidate minimum ratio10 takes a value of-4.77 (fractional value), EPRE takes a fractional value. Therefore, further, the power-floating point value mapping relationship further includes a demodulation reference power-floating point value mapping relationship (e.g., a relationship list). Therefore, when the power ratio candidate minimum value ratio10 is an integer, different candidate conversion precisions B can be respectively specifiedmaxA corresponding relation list of the floating point value f (EPRE) and the demodulation reference power EPRE, or a corresponding relation list of the fixed point value Q (EPRE) and the demodulation reference power EPRE; and respectively specify different candidate conversion accuracies B when the power ratio candidate minimum value ratio10 is a decimalmaxThe corresponding floating point value f (Npower) and the input power Npower, or the corresponding fixed point value q (Npower) and the input power Npower. For example, corresponding to Table 4, "ratio 10 is defined as an integer, BmaxWhen the bit is 14 bit; a relation list of fixed point values Q (EPRE) and demodulation reference power EPRE, ratio10 being decimal, BmaxWhen the bit is 14 bit; fixed point value Q (Npower) and input power Npower' ratio10 is integer, BmaxWhen the bit is 13 bit; a relation list of fixed point values Q (EPRE) and demodulation reference power EPRE, ratio10 being decimal, BmaxWhen the bit is 13 bit; a list of relationships of the fixed-point values q (Npower) to the input power Npower, and so on, a list of relationships of the 5 fixed-point values q (EPRE) to the demodulation reference power EPRE, and a list of relationships of the 5 fixed-point values q (Npower) to the input power Npower may be determined. For example, as shown in tables 6.1-6.4, there are enumerated a list of relationships between 2 of the above-mentioned fixed-point values q (EPRE) and the demodulation reference power EPRE, and a list of relationships between 2 of the above-mentioned fixed-point values q (Npower) and the input power Npower.

The embodiment has the advantages that the floating point value or the fixed point value corresponding to each input power Npower can be determined by table lookup only by establishing the corresponding relation list when the power ratio candidate minimum ratio10 is an integer or a decimal, so that the number of the relation lists is reduced, the operation amount of the processor is further reduced, and the table lookup efficiency is improved.
It should be noted that, as shown in fig. 1, for step S102, "determining whether all actual values of the power ratio in the preset configuration can be obtained, a minimum value of all actual values is called a power ratio actual minimum value", if the determination result indicates that all actual values of the power ratio in the preset configuration cannot be obtained, step S1022 is executed: and if not, acquiring a theoretical minimum value of the power ratio, and determining the actual maximum conversion precision of the floating point conversion of all the input power in the actual power range according to the maximum input power and the theoretical minimum value of the power ratio.
It will be appreciated that the expression y in terms of arithmetic floating point values is 10(Npower-ratio0)/20It is noted that the larger the arithmetic floating point value obtained when the power is smaller than the actual minimum value ratio0, and it is understood from equation (1) that the maximum conversion precision determined based on the maximum arithmetic floating point value can satisfy the floating point conversion of all the input powers Npower within the actual power range. It can be seen that when the actual minimum value of the power ratio cannot be obtained (i.e. when the entire actual value of the power ratio cannot be obtained), the corresponding actual maximum conversion accuracy can be determined by determining the maximum theoretical arithmetic floating point value by means of the theoretical minimum value ratio of the power ratio 100. It is understood that the theoretical minimum of power ratio is the minimum candidate minimum of power ratio. Illustratively, the power ratio theoretical minimum ratio100 ═ 4.77.
It can be understood that, in the above case that all the actual values of the power ratio under the preset configuration cannot be obtained, the relationship list between the floating point value f (Npower) and the input power Npower or the relationship list between the fixed point value q (Npower) and the input power Npower (i.e. the input power-floating point value mapping relationship or the input power-fixed point value mapping relationship) may be formulated first, and the converted floating point value or fixed point value corresponding to each input power Npower may be determined by comparing and looking up the table, so as to greatly reduce the operation overhead of the processor and save the time for floating point conversion. In the interest of brevity, the same will not be described one by one.

Specifically, the mapping relationship between the power and the floating-point value and the fixed-point value may be a relationship list of the fixed-point value, the floating-point value, and the input power Npower (or the demodulation reference power EPRE). For the sake of brevity, the same parts in formulating the relationship list are not set forth one by one.
