The scheme provided by the application will be described in detail by specific examples.
Example one
In the method for allocating power to a node in a digital communication system in this embodiment, the number of the second frequency domain unit bandwidth, which is larger than or the largest effective transmission frequency domain unit bandwidth, of the first frequency domain unit bandwidth is obtained, the power value of the second frequency domain unit bandwidth is obtained by combining the power requirement of the system unit bandwidth, and the number of the total second frequency domain unit bandwidth occupied by the signal is combined, so as to obtain effective transmission power. As shown in fig. 4, the method mainly comprises the following steps:
step S401, obtain the number of the second frequency domain unit bandwidths of the larger or largest effective transmission within the first frequency domain unit bandwidth.
In this embodiment, the obtaining manner may be determined by one or more of the following manners, but is not limited to the following manners:
1) the manner of measurement and statistics;
2) historical scheduling or transmission information.
3) Scheduling-based resource allocation information;
4) scheduling-free resource allocation information based on history;
the obtained value is the number of second frequency domain unit bandwidths of the larger or largest effective transmission within the first frequency domain unit bandwidth.
In this embodiment, the first frequency-domain unit bandwidth is greater than the second frequency-domain unit bandwidth.
In the above embodiment, the first frequency domain unit bandwidth may be 1MHz, 2MHz, or a positive integer multiple of 1 MHz.
In the above embodiment, the second frequency domain unit bandwidth may be a subcarrier (1.25KHz, 5KHz, 7.5KHz, 15KHz, 30KHz, 60KHz,120KHz or a multiple of a power of 2 of 15KHz, or 15KHz divided by M, where M is a positive integer), one or N rb (resource block) or re (resource element), where N is a positive integer.
In the above embodiments, when the first frequency-domain unit bandwidth is not an integer multiple of the number of transmissions for which the second frequency-domain unit bandwidth is effective, the rounding-up or rounding-down may be performed.
Step S402, obtaining the power value of the second frequency domain unit bandwidth according to the obtained number information of the second frequency domain unit bandwidth and the power requirement of the system unit bandwidth, and further obtaining the effective transmission power of the signal according to the number of the total second frequency domain unit bandwidth occupied by the signal, wherein the effective transmission power is used as an input item for calculating the final transmission power.
In this embodiment, the power requirement of the system per bandwidth may be different according to different frequency band ranges or different system devices, and typical values may be 7dBm/MHz, 10dBm/MHz, 14dBm/MHz, 17dBm/MHz, and M dBm/MHz, where M is a positive integer greater than 0.
In a preferred embodiment, the power requirement of the system unit bandwidth is 10dBm/MHz, the first frequency domain unit bandwidth is 1MHz, the maximum number of valid second frequency domain unit bandwidths in the first frequency domain unit bandwidth is 5, and the number of second frequency domain unit bandwidths occupied by valid signals in the whole transmission bandwidth or bandwidth group is 50. Then a power of 10dBm +10 log (50/5) ═ 20dBm is obtained as an effective input term, where 10dBm corresponds to the power requirement per unit bandwidth of the system, 50 represents the number of second frequency domain units occupied by the effective signal within the entire transmit bandwidth or bandwidth group, and 5 represents the maximum effective number of second frequency domain unit bandwidths within the first frequency domain unit bandwidth.
Example two
Compared with the first embodiment, the same point is a method for allocating power to nodes in a digital communication system, which obtains the number of the second frequency domain unit bandwidth of the larger or largest effective transmission of the first frequency domain unit bandwidth, combines the power requirement of the system unit bandwidth to obtain the power value of the second frequency domain unit bandwidth, and combines the number of the total second frequency domain unit bandwidth occupied by the signal to further obtain the effective transmission power. The difference is that the method of scanning with the third frequency unit bandwidth as the step length in the interval of the first frequency unit bandwidth to obtain the number of the second frequency unit bandwidth in the first frequency unit bandwidth.
As shown in fig. 5, the present embodiment mainly includes the following steps:
step S501, in the interval of the first frequency domain unit, taking the third frequency domain unit as the step size, and counting the number of the second frequency domain unit bandwidths of the effective transmission in the effective transmission bandwidth.
In this embodiment, the first frequency domain unit bandwidth is equal to or greater than the third frequency domain unit bandwidth, and the third frequency domain unit bandwidth is equal to or greater than the second frequency domain unit bandwidth.
In this embodiment, the second frequency domain unit bandwidth may take a value of one or N subcarriers (1.25KHz, 5KHz, 7.5KHz, 15KHz, 30KHz, 60KHz,120KHz or a multiple of a power of 2 of 15KHz, or 15KHz divided by M, where M is a positive integer), one or N rbs (resource block) or res (resource element), where N is a positive integer.
In this embodiment, the typical value of the third frequency domain unit bandwidth and the typical value of the second frequency domain unit bandwidth may be the same or different, and the requirement that the third frequency domain unit bandwidth is greater than or equal to the second frequency domain unit bandwidth needs to be met. For example, in the present embodiment, the first frequency domain unit bandwidth, the second frequency domain unit bandwidth, and the third frequency domain unit bandwidth may take typical values, which are 1MHz, one subcarrier, and one subcarrier, respectively.
In step S501, the third frequency domain unit bandwidth is used as a step length, the number of the second frequency domain unit bandwidths that are effectively transmitted is measured or counted in the system bandwidth or the effective transmission bandwidth range, and after the measurement and the counting are completed, the larger or the largest number of the second frequency domain unit bandwidths that are effectively transmitted in the first frequency domain unit bandwidth is obtained. It should be noted that this is only a preferred method of obtaining a second frequency domain unit of larger or largest effective transmission within the bandwidth of the first frequency domain unit.
In this embodiment, the mapping method for the signals is not limited, and may be continuous mapping, discontinuous mapping, or irregular mapping.
In this embodiment, the granularity of mapping is also not limited, and may be RB level, subband level, or customized frequency domain granularity.
The mapping manner of the signal of this embodiment can be referred to as fig. 6, which shows different mapping patterns of the signal. (1) The representation is a continuous mapping mode; (2) the expression shows the mapping mode with equal intervals; (3) the patterns (4) and (5) are not equally spaced, and may be referred to as non-equally spaced patterns.
Step S502, according to the above information and the power requirement of the unit bandwidth of the system, the power value of the unit bandwidth of the second frequency domain is obtained, and further the effective transmission power is obtained. This step is the same as step 402 of the first embodiment, and is not described again here.

The difference is that the signals are of different types for the signal under consideration.
As shown in fig. 7, the method of this embodiment mainly includes the following steps:

In this embodiment, for different types of signals, corresponding statistics may be performed according to the priority. For different types of signals, the signal types with high priority can be counted preferentially, the signals with different priorities can be counted together, the signal types with low priority can not be counted, or when the signals with different priorities exist, the node capability is considered, and corresponding processing is carried out.
