Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for generating a physical cell identity, and an electronic device.
Background
Physical Cell Identity (PCI) is used to distinguish between different cells, each of which has a PCI corresponding to it.
In the prior art, a total of 504 different PCI values are defined in the 4th generation mobile communication technology (4G) Long Term Evolution (LTE), and each PCI corresponds to a specific downlink reference signal sequence. The set of all PCIs is divided into 168 groups, each containing 3 cell identification codes (IDs). In LTE network planning, it is desirable to avoid equal values for PCI mod (mod) 3, PCI mod6, and PCI mod 30 for neighboring cells. From the physical layer, the PCI is composed of a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS), and can be obtained by calculating the formula PCI +3 SSS. The specific PCI is determined by retrieving PSS and SSS in the LTE cell search procedure, which are combined. The New Radio (NR) system of the fifth generation mobile communication technology (5G) defines 1008 PCIs, and is divided into 336 groups by a modulo-3 method, where each group includes 3 cell IDs, and the value range is 0-335. The 5G NR PCI planning should follow the principles of non-conflict, non-confusion, and optimization.
However, the 5G NR system has 1008 PCI codes, and if PCI planning of the 4G network is used, 504 PCI codes cannot be used in the 5G NR system, which results in waste of PCI code resources and failure to achieve the maximum PCI code resource multiplexing distance. If the PCI planning of the 5G NR system is performed independently without using the PCI planning of the 4G network, interference between the systems will be introduced.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The LTE of 4G era defines 504 different PCIs (value range 0-503), and each PCI corresponds to a specific downlink reference signal sequence. The set of all PCIs is divided into 168 groups (range 0-167) each containing 3 cell IDs (range 0-2). In LTE network planning, it is necessary to avoid equal values for "PCI mod 3", "PCI mod 6", and "PCI mod 30" for neighboring cells. So-called "mode 3 interference", "mode 6 interference", "mode 30 interference" avoidance.
(1) If the values of PCI mod3 of the neighboring cells are the same, PSSs of the neighboring cells are the same, causing mutual interference of the PSSs.
(2) Under the condition of fixed time domain position, the downlink cell specific reference signal has 6 frequency shifts (frequency shift) in the frequency domain. If the PCI mod6 values of neighboring cells are the same, the positions of the downlink cell-specific reference signals in the frequency domain overlap, which may cause mutual interference between the reference signals.
(3) The mode 30 interferes: DMRS and SRS information are carried in the PUSCH channel, and these two reference signals are important for channel estimation and demodulation. They are composed of 30 basic ZC sequences, i.e. there are 30 different combinations of sequences. If the PCI mod 30 values of the neighboring cells are the same, the same ZC sequence is used, which causes mutual interference between the uplink DMRS and SRS.
In the 5G era, 1008 PCIs are defined in the 5G NR system, and are divided into 336 groups by a modulo 3 method, where the value range is 0 to 335, and each group includes 3 cell IDs.
The 5G NR PCI project should follow the following principles:
(1) non-conflict principle: ensuring that the PCIs between the same-frequency adjacent cells are different;
(2) not to obscure the principles: ensuring that the PCI values of the same-frequency adjacent cells of a certain cell are not equal, and selecting the PCI value with the optimal interference as much as possible between the adjacent cells, namely configuring different PCI modules 3 and 30;
(3) optimization principle: ensuring sufficient reuse distance with the PCI cell.
In the prior art, a main research object is a planning method and equipment of 504 PCI codes of an LTE network, and the method and equipment mainly plan that PCI follows the principles of no conflict and no confusion, and divide two continuous PCI spaces from a PCI resource segment, wherein one PCI space is used for distributing PCI of a pico base station cell; and the other PCI space is used for distributing the PCI of the macro base station cell, and the PCI space distributed to the macro base station cell is large enough, so that the PCI multiplexing distance of the macro base station cell is long enough, and the PCI space adopted by the macro base station cell and the PCI resource reserved for capacity expansion are calculated. The PCI multiplexing distance is far enough, namely the number of rings forming a macro cell cluster enough for the macro base station is multiplied by the diameter of a cell; the PCI space is large enough that the number of assignable PCIs is at least equal to the total number of cells of a sufficient cluster of macrocells such that the probability of PCI collisions with microcells is low. For example, the method for allocating the PCI space includes: allocating a continuous PCI space for the pico base station cell, wherein the range is 1-50; allocating a continuous PCI space with a sufficient size to the cells of the macro cell cluster base station, wherein the range is 51-321; and reserving a continuous PCI space for the macro cell cluster base station, wherein the range is 322 and 447, and the expansion of the macro base station is reserved. The method can basically meet the requirement that the PCI is not conflicted and confused, and part of research considers the influence of the PCI model 3 and the PCI model 6 to carry out related PCI planning, thereby avoiding the occurrence of more serious interference between reference signals of the 4G network.
The scheme in the prior art mainly plans 504 PCI codes of a 4G LTE network, achieves the purposes of no conflict and no confusion, and partially considers the interference conditions of a mode 3 and a mode 6, but does not have research and attention at present for the planning of 1008 PCI codes of a 5G NR network and the similarities and the associations of the PCI of the 5G NR network and the PCI planning of the 4G network.
The prior art scheme mainly aims at the planning realization of PCI codes of a 4G LTE network, the LTE network only has 504 PCI codes, but a 5G NR network has 1008 PCI codes, if PCI planning equipment of the 4G network is used, 504 PCI codes (504-1007) of the 5G network cannot be used, PCI code resources are wasted, and the maximum PCI code resource multiplexing distance cannot be realized; on the other hand, the PCI code deployment requirement of the 5G NR network is very similar to that of the 4G network, the 4G network has been deployed for 7 years at present, the existing network has been subjected to sufficient network optimization, the deployed PCI codes of the existing network have achieved scientificity and rationality of deployment to the maximum extent, if the PCI code resource planning result of the existing network 4G is unreasonably utilized, a large amount of manpower and material resources are re-planned and optimized, and interference between the 4G LTE system and the 5G NR system will be introduced.
Aiming at the defects, the embodiment of the invention is based on the concentric ring array innovation that 1008 PCI codes are combined with the concentric ring array to form a PCI ring array, and the PCI code resource planning result of the existing network 4G network is combined with the PCI ring array, so that the PCI of the 5G NR network is reasonably deployed, the maximum PCI code resource multiplexing distance is reached, the effects of saving manpower, material resources and time cost are further achieved, the resource waste is avoided, and the inter-system interference is also avoided.
Fig. 1 is a schematic diagram of a PCI generation method according to an embodiment of the present invention, and as shown in fig. 1, an execution subject of the PCI generation method according to the embodiment of the present invention is a PCI generation device. The method comprises the following steps:
step S101, judging whether a target base station to be planned is co-located with a base station of a previous generation network.
Specifically, in the embodiment of the present invention, it is necessary to previously construct a concentric circular ring array composed of m concentric circular rings into which a circle including the region S to be planned is divided, CiIs the ith ring, and m is more than or equal to 2. The circle center of the concentric ring is P, the circle center P is taken as a reference point, and the longitude and latitude of P are (P)Lo，PLa)，CiHas a width of Δ di。
The circle containing the area S to be planned can be determined in two ways:
1. the circle containing the area S to be planned may be the minimum circumscribed circle of the area S to be planned and satisfy the following formula:
0≤Δdi≤R
wherein, Δ diThe width of the ith circular ring is shown, R is the radius of the minimum circumcircle of the region S to be planned, m is the number of concentric circular rings, i belongs to (1, 2.. m), and m is more than or equal to 2.

And satisfies the following formula:
wherein, Δ diIs the width of the ith circle,/1And l2The length and the width of the circumscribed rectangle of the area S to be planned are respectively, m is the number of concentric rings and is more than or equal to 2.
And the value of m is calculated by the following equation:
wherein, Δ diIs the width of the ith circle,/1And l2The length and the width of the circumscribed rectangle of the area S to be planned are respectively, m is the number of concentric rings and is more than or equal to 2.
Fig. 2 is a schematic diagram of a concentric ring array according to an embodiment of the present invention, as shown in fig. 2, where m is 4 as an example, that is, the concentric ring array includes four concentric rings, and the region S to be planned is not shown in fig. 2.
After the concentric ring array is constructed, it is necessary to determine whether the target base station to be planned currently is co-located with the base station of the previous generation network. And determining the PCI of each cell of the target base station by combining the concentric ring array according to the judgment result.
And if the target base station to be planned currently is the 5G NR base station, the previous generation network is a 4G LTE network.
Step S102, if a base station of a previous generation network co-located with the target base station exists, generating the PCI of each cell of the target base station based on the PCI of the co-located base station and the position of the target base station in a preset concentric ring array, wherein the concentric ring array is composed of a plurality of concentric rings divided by a circle containing an area to be planned.
Specifically, after judging whether the target base station to be planned currently is co-located with the base station of the previous generation network, determining the PCI of each cell of the target base station according to the judgment result and the concentric ring array.
And if the base station of the previous generation network co-located with the target base station exists, generating the PCI of each cell of the target base station based on the PCI of the co-located base station and the position of the target base station in the preset concentric ring array.
Whether a base station of a previous generation network co-located with the target base station exists or not can be judged according to the longitude and latitude of the target base station, and the position of the target base station in the preset concentric ring array is determined according to the longitude and latitude of the target base station.
According to the PCI generation method provided by the embodiment of the invention, the PCI of each cell of the base station to be planned is generated by combining the PCI of the cell of the previous generation network according to the position of the base station to be planned in the preset concentric ring array, so that the resource waste is avoided, and the interference between systems is also avoided.
Based on any of the above embodiments, further, the generating the PCIs of each cell of the target base station based on the PCIs of the co-located base station and the position of the target base station in the preset concentric ring array specifically includes:
determining the number of the concentric ring where the target base station is located according to the longitude and latitude of the target base station; the concentric circular rings are numbered in advance according to the sequence that the radius is from small to large or from large to small;
and generating the PCI of each cell of the target base station based on the parity of the number of the concentric ring where the target base station is located and the PCI of the co-located base station.
Specifically, in the embodiment of the present invention, the specific steps of generating the PCI of each cell of the target base station based on the PCI of the co-located base station and the position of the target base station in the preset concentric ring array are as follows:
firstly, the number of the concentric ring where the target base station is located is determined according to the longitude and latitude of the target base station.
In the process of constructing the concentric ring array, a plurality of concentric rings are numbered in advance according to the sequence of the radius from small to large or from large to small, so that the odd-even quadrant attribute of each ring is constructed.
Fig. 3 is a schematic diagram of the distribution of odd-even quadrants of a ring according to an embodiment of the present invention, and as shown in fig. 3, a ring closest to a circle center P is defined, i.e., the ring with the smallest radius is the 1 st ring C1The numbers are sequentially numbered according to the sequence of the radii from small to large, and the ith ring is CiThe circle with the largest radius is the mth circle Cm。C1The region is a singular limit, C2The region is an even quadrant, C3The region is a singular quadrant, and by analogy, the odd-even quadrant attribute of each ring is constructed.
Definition ai1Is CiSmall radius of (a)i2Is CiIs large radius.
Definition ai3Is CiQuadrant property of ai30 represents CiThe quadrant attribute of (A) is even imageOtherwise, ai31 represents CiThe quadrant property of (C) is odd quadrant, from which C can be calculatediOf the belonging parity quadranti3I ∈ (1, 2.. m), i being the number of the ring.
After the concentric ring array is constructed, the serial number of the concentric ring where the target base station is located can be determined according to the longitude and latitude of the target base station.
Setting the longitude and latitude of the target base station as (B)Lo，BLa) The distance from the target base station to the reference point P is D (unit: rice) and the longitude and latitude of the reference point P are (P)Lo，PLa) Then, D can be determined by a formula for calculating the distance between any two points according to the longitude and latitude of the two points on the earth, wherein the formula is as follows:
D＝6371004*Arccos(sin(BLa)*sin(PLa)+cos(BLa)*cos(PLa)*cos(BLo-PLo))*Pi/180
according to the distance D, CiSmall radius a ofi1And CiLarge radius a ofi2The relationship (c) determines the number of the concentric ring where the target base station is located. When a isi1＜D≤ai2Then the target base station is determined to be located at CiIn the area, the number of the concentric ring where the target base station is located is determined to be i, and then the quadrant attribute of the target base station is judged. If the number of the concentric ring where the target base station is located is an odd number, the quadrant attribute of the target base station is an odd quadrant; and if the number of the concentric ring where the target base station is located is an even number, the quadrant attribute of the target base station is an even quadrant.
Then, the PCIs of the respective cells of the target base station are generated based on the parity of the number of the concentric ring where the target base station is located and the PCIs of the co-located base stations.
The PCI generation method provided by the embodiment of the invention distinguishes the concentric rings according to the parity of the serial numbers, and the PCIs of all cells of the target base station positioned in different quadrant attributes are generated in different modes, thereby further avoiding the interference between systems.

and if the number of the concentric ring where the target base station is located is an odd number, generating the PCI of each cell of the target base station according to the PCI of the co-located base station and a preset constant, wherein the generated value of the PCI of the cell of the target base station is equal to the value of the PCI of the corresponding cell in the co-located base station plus the preset constant.
Specifically, fig. 4 is a logic flow diagram for generating a PCI of a co-located base station according to an embodiment of the present invention, as shown in fig. 4, in the embodiment of the present invention, if the number of a concentric ring where a target base station is located is an even number, that is, the quadrant attribute of the target base station is an even quadrant, the PCI code of the cell of the target base station inherits the PCI code resource of a previous generation network co-located with the target base station, that is, the generated PCI of the cell of the target base station is equal to the PCI of a corresponding cell in the co-located base station.
If the number of the concentric ring where the target base station is located is an odd number, that is, the quadrant attribute of the target base station is an odd quadrant, a preset constant is added to the cell PCI code of the target base station on the basis of the PCI code of the co-located previous generation network, that is, the generated value of the PCI of the cell of the target base station is equal to the value of the PCI of the corresponding cell in the co-located base station plus the preset constant.
The preset constant is determined by the actual network scenario.
For example, there are 504 PCI codes in the 4G LTE network, 1008 PCI codes in the 5G NR network are planned, and if the base station to be planned is the 5G NR base station, the preset constant is 504. Setting PCI of cell of 5G NR base station to be planned as PCINRThe PCI of the cell of the 4G LTE base station co-located with the base station is PCI4GThen PCINRThe calculation formula of (a) is as follows:
as shown in fig. 4, polling is performed on all co-located NR stations, and in combination with the concentric ring array, PCI code resource deployment conditions of all cells of the 5G NR base stations co-located with the 4G LTE base station can be further calculated.
In the PCI generating method provided in the embodiments of the present invention, the concentric rings are distinguished according to parity of numbers, the PCI of each cell of the base station located in the even quadrant inherits the PCI code resource of the previous generation network, and the PCI of each cell of the base station located in the odd quadrant adds a constant on the basis of the PCI code resource of the previous generation network, thereby further avoiding inter-system interference.

and if the base station of the previous generation network co-located with the target base station does not exist, generating the PCI of each cell of the target base station based on the PCI new code set of the previous generation network and the position of the target base station in a preset concentric ring array.
Specifically, in the embodiment of the present invention, after determining whether the target base station to be planned currently is co-located with the base station of the previous generation network, the PCI of each cell of the target base station is determined according to the determination result and the concentric ring array.
Each generation of network reserves two kinds of PCI code resources, including PCI new code resources and PCI expansion code resources, the set of PCI new code resources is also called PCI new code set or PCI new code resource pool, and the set of PCI expansion code resources is also called PCI expansion code set or PCI expansion code resource pool.
In the embodiment of the invention, if the base station of the previous generation network co-located with the target base station does not exist, the PCI of each cell of the target base station is generated based on the PCI new code set of the previous generation network and the position of the target base station in the preset concentric ring array.
Whether a base station of a previous generation network co-located with the target base station exists or not can be judged according to the longitude and latitude of the target base station, and the position of the target base station in the preset concentric ring array is determined according to the longitude and latitude of the target base station.

Specifically, in the embodiment of the present invention, based on the PCI new code set of the previous generation network and the position of the target base station in the preset concentric ring array, the specific steps of generating the PCI of each cell of the target base station are as follows:
firstly, the number of the concentric ring where the target base station is located is determined according to the longitude and latitude of the target base station.
The specific method for determining the number of the concentric ring where the target base station is located according to the longitude and latitude of the target base station is the same as that in the above embodiment, and is not described here again.
Then, based on the parity of the number of the concentric ring where the target base station is located and the PCI new code set of the previous generation network, the PCIs of each cell of the target base station are generated.
The PCI generation method provided by the embodiment of the invention distinguishes the concentric rings according to the parity of the serial numbers, and the PCIs of all cells of the target base station positioned in different quadrant attributes are generated in different modes, thereby further avoiding the interference between systems.
Based on any of the above embodiments, further, the generating the PCI of each cell of the target base station based on the parity of the number of the concentric ring where the target base station is located and the PCI new code set of the previous generation network specifically includes:
if the number of the concentric ring where the target base station is located is an odd number, generating the PCI of each cell of the target base station according to the PCI new code set of the previous generation network;
and if the number of the concentric ring where the target base station is located is an even number, determining a new PCI new code set according to the PCI new code set of the previous generation network, and generating the PCI of each cell of the target base station based on the new PCI new code set.
Specifically, fig. 5 is a logic flow diagram for generating PCIs of a non-co-located base station according to an embodiment of the present invention, as shown in fig. 5, in the embodiment of the present invention, for the non-co-located base station, if the number of the concentric ring where the target base station is located is odd, that is, the quadrant attribute of the target base station is a singular limit, the PCIs of each cell of the target base station are generated according to the set of PCI new codes of the previous generation network, that is, a set of PCIs is selected from the set of PCI new codes of the previous generation network as the PCIs of each cell of the target base station.

The specific way of determining the new PCI new code set according to the PCI new code set of the previous generation network may be: and adding a preset constant to each PCI in the PCI new code set of the previous generation network, wherein the set formed by the new PCIs is the new PCI new code set.
The preset constant is determined by the actual network scenario.
For example, there are 504 PCI codes in the 4G LTE network, 1008 PCI codes in the 5G NR network are planned, and if the base station to be planned is the 5G NR base station, the preset constant is 504. Setting the PCI new code set of the 5G NR network to be planned as R1And the PCI new code set of the 4G LTE network is R1', the PCI new code set of a single ring is RCThen R is1And RCThe calculation formula of (a) is as follows:
R1＝R′1∪(R′1+504)
wherein R'1+504 denotes the new PCI new code set, i.e., from R'1504 is added to each PCI in the set of new PCIs.
Setting PCI expansion code set of 5G NR network to be planned as R2And the PCI expansion code set of the 4G LTE network is R'2Then R is2The calculation formula of (a) is as follows:
R2＝R′2∪(R′2+504)
wherein R'2+504 denotes a new set of PCI flash codes, i.e. from R'2504 is added to each PCI in the set of new PCIs.
By adopting the above mode, the new code building resource pool of the 5G NR is 2 times of the new code building resource pool of the 4G LTE, and similarly, the capacity expansion code resource pool of the 5G NR is 2 times of the capacity expansion code resource pool of the 4G LTE, and the capacity expansion code resource pool of the 5G NR is reserved, so that the subsequent capacity expansion use is facilitated. The method can ensure that the PCI deployed by the co-located NR base station and the PCI deployed by the newly-built NR base station keep the maximum multiplexing distance, thereby avoiding interference.
