Description

Network system, cell access method, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a network system, a cell access method, a terminal, and a network device.

Background

The reason cellular networks are widely used in the prior art is derived from the mathematical conclusion that a plane is covered with circles of the same radius, and the number of circles used is the least when the center of the circle is at the center of each regular hexagon of the regular hexagonal grid, i.e. when the center of the circle is at a grid point of the regular triangular grid. Although the graph that can cover the maximum area with the minimum nodes is still an unknown problem to be solved even if the nodes are required to be on a grid with translation characteristics like a lattice, in communication, it is usually reasonable to use a circle to express the practical requirement, so that the regular triangle grid or the simple hexagon grid is the best choice in view of saving the equipment construction cost. The network thus formed is overlaid together and shaped much like a cell, and is therefore referred to as a cellular network.

In the prior art, a cell is defined as an area for providing wireless communication services to users, and is a basic unit of a wireless network. The number of cells supported by the base station is determined by "number of sectors x number of carriers per sector". In a 3 x2 configuration, the entire circular area is divided into 3 sectors for coverage, with 2 carrier frequencies per sector, and there are a total of 6 cells. (but the maximum number of cells for a base station is more than 6).

One cellular network cell corresponds to one physical cell identity, a global cell identity and a set of system messages. The system information broadcast is realized by the network operation, and is sent periodically or according to the need, after the terminal (User Equipment, UE) is started, the terminal will receive the synchronization signal and the system information sent by the base station (gNB), wherein the system information includes the Physical Random Access Channel (PRACH) configuration index, the logical root sequence initial value, the cyclic shift index, the uplink and downlink configuration index of the cell are equal to the parameters related to the Random Access. When accessing a gNB network, UE must search and determine a serving cell through the cell, then acquire system information of the cell, initiate random access and other processes, and thus obtain frequency and symbol synchronization with a certain specific cell; 2) acquiring a system frame clock, namely the initial position of a downlink frame; 3) a Physical-layer Cell Identity (PCI) of the Cell is determined.

The UE not only needs to perform cell search when being powered on, but also, in order to support mobility (mobility), the UE continuously searches for neighbor cells, acquires synchronization, and estimates the reception quality of the cell signal, thereby determining whether to perform handover (when the UE is in an RRC _ CONNECTED state) cell selection and/or cell reselection (when the UE is in an RRC _ IDLE state). When searching for a cell, the sequence of searching is to search for a co-frequency cell, a pilot frequency cell and then find a cell between different systems. After the previous cell search process, the terminal still needs to determine whether the signal quality of the cell meets a certain requirement, so as to further determine whether the terminal can camp on the cell. When the UE is switched, the determined target cell is also selected for switching.

For a specific UE, such as a drone, an aircraft, a robotic arm, etc., the following problems may exist:

1) downlink interference, namely, the unmanned aerial vehicle receives a large number of adjacent cells in the air, and the number of the adjacent cells is more than ten, so that the downlink average SINR is reduced to about 0 db.

2) Mobility problem, part of the interfering neighbors come from the distant base station: the urban scene with ISD of 500m can receive 2.5km of outer cells, the frequent switching is carried out in the air, and the switching failure and the number of times of disconnection are 2-5 times higher than the ground

3) The path loss of the unmanned aerial vehicle ascending to the plurality of adjacent cells is close, and the interference on the adjacent cells is greatly influenced. The unmanned aerial vehicle uplink to a plurality of surrounding base stations are all LOS paths, and the uplink service of the unmanned aerial vehicle terminal can interfere with the uplink performance of ground users in surrounding adjacent cells. In the traditional ground UE power control, only the path loss and SINR of the cell are considered, and the interference to the adjacent cell is not considered.

In the prior art, a widely adopted cellular network is a planar cell, which has good service performance for traditional ground UE, but for special UE such as unmanned aerial vehicle, due to channel models caused by its flight characteristics (flight speed, flight altitude difference), propagation characteristics are different, and the application of the planar cell brings too much complexity to the service of the unmanned aerial vehicle and the switching of the unmanned aerial vehicle, the access and the management of the neighboring cell relation.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

As shown in fig. 1, an embodiment of the present invention provides a network system, including: at least one cell, wherein the coverage area providing wireless communication service and/or signaling control for users is at least one definable stereo area.

In the network system described in this embodiment, the defined cell is a three-dimensional area that provides a wireless communication service for a user, and is not a sector or a planar area in the prior art, where the cell is formed by at least one network device, and the network device includes at least one of a base station, a transmission point, a reception point, a central Unit (central RAN Unit), a distributed RAN Unit (distributed RAN Unit), an indoor baseband processing Unit (BBU), a Remote Radio Unit (Radio Remote Unit, RRU), a relay, a communication balloon, a flying aircraft base station, an antenna, and a satellite. The antennas herein may be used with other devices, such as base stations, or as stand-alone devices.

Optionally, the spatial range of the stereo region includes: the space grid is a subdivision network formed by recursively subdividing the sphere according to preset intervals in the three dimensions of longitude, latitude and height, and carrying out grid division and coding on the whole earth three-dimensional space.

That is, at least one of one or more base stations, transmission points, reception points, central units, distribution units, BBUs, RRUs, relays, communication balloons, flying aircraft base stations, antennas, satellites may form the cell, or a stereo cell, and a plurality of stereo cells may form a stereo cell group.

A stereo cell may be composed of one or more spatial grids or spatial grid groups, and may associate one or more grid arrays or sequence code groups or sequences, and a stereo cell may also associate index numbers of one or more sequence code groups, sequences of spatial grid groups, and/or index numbers of sequences;

in an optional embodiment of the present invention, the cell corresponds to at least one of the following information:

at least one spatial grid array/sequence code group/sequence;

index number/index number of index number/sequence of at least one index number/sequence code group of spatial grid array;

a sequence of spatial grid groups;

index number of the sequence of the spatial grid cluster.

In an optional embodiment of the present invention, one cell corresponds to one global cell identifier, which is a cell identifier configured for a cell by a higher layer.

Optionally, the spatial grid is: the spatial grid should mesh and encode the entire earth's volumetric space. The sphere is recursively subdivided in the longitude dimension, the latitude dimension and the height dimension at certain intervals, and the method has the advantages of longitude and latitude consistency, orthogonality and the like. The grid has the advantages of being identifiable, positionable, indexable, multi-scale and automatically spatial-associated, and can be used as a spatial reference framework for spatial management and control and big data management.

The voxels of the spatial grid are multiscale and each scale voxel fills the entire geospatial space seamlessly, without overlap.

Taking GeoSOT as an example, a GeoSOT geospace reference grid system: a global equal-longitude and latitude Subdivision grid system (geospatial coordinate global Subdivision grid with One-dimension-inter on Two to n-th power, geohot for short) called 2n One-dimensional integer array.

The GeoSOT geospatial reference grid coding usually adopts 32-bit 8-system numerical values, the recording length is equivalent to 4 Chinese characters, at most 8 Chinese characters (64 bits), the 1 st to 9 th bits are degree level grid coding, the 10 th to 15 th bits are hierarchical grid coding, the 16 th to 21 th bits are second level grid coding, and the 22 th to 32 th bits are grid coding below second; the coding length represents the grid level, and the longer the coding length is, the thinner the grid is; when writing the code, the front is at the beginning of G, the degree second level codes are separated by "-", and the second level codes are separated by ". multidot.", the form is as follows: gddddddddddddd-mmmmmm-ssssss. uuuuuuuuuuu

And has the following characteristics:

1) is three-dimensional. The GeoSOT geospatial reference grid completely covers the geospatial from the center of the earth to 50000 km high altitude, the whole earth and the adjacent space are divided into 1030 voxels with the scale of 1-32, and each voxel has a unique integer code.

2) Consistency of the three-dimensional mesh and the spherical mesh. When the GeoSOT geospatial reference grid height is the geoheight (or the earth average radius), the height dimension is degraded, and the true three-dimensional geospatial reference grid framework becomes the reference grid framework on the two-dimensional earth sphere. Therefore, the GeoSOT three-dimensional space reference grid and the spherical space reference grid form seamless connection, and the three-dimensional space reference grid can also be seamlessly associated with spherical data.

3) And (4) inclusion. The GeoSOT grid has a good containing relation with domestic and foreign longitude and latitude standard grids, and the GeoSOT grid contains domestic and foreign main surveying and mapping, weather, ocean and national geographic grids.

The GeoSOT grid is strictly recurrently and quadrilaterally divided after being expanded for 3 times through a latitude and longitude range space on the earth surface, so that the whole earth is divided into a hierarchical grid system with the scale of whole to the globe and the scale of centimeter, whole to the whole second and below the second. The 1 st spatial expansion is to expand the whole earth surface to 512 degrees multiplied by 512 degrees, the center of a patch coincides with the intersection point of the equator and the original meridian, and then the patch is recursively quadripun until 1 degree grid unit is obtained; the 2 nd spatial expansion is to expand the 1 degree grid cell from 60 ' to 64 ', and then to recursion four-fork subdivision until the 1 ' grid cell; the 3 rd spatial expansion is to expand the 1' grid cell from 60 "to 64" and then recursively bifurcate until a1 "grid cell. 1 'the lower subdivision unit adopts four-fork division directly, and 32 stages are up to (1/2048'). In this way, the longitude and latitude space of the whole earth surface is divided into a multi-stage grid system covering the whole world by a strict 2-point method in the longitude direction and the latitude direction. Therefore, the voxels of the GeoSOT geospatial reference grid are multiscale, and each scale of voxels fills the entire geospatial space seamlessly, without overlap. The spatial grid is a method for recursive quadtree subdivision according to equal longitude and latitude in the warp direction and the weft direction, the spherical surface of the earth is subjected to specification division, then, the divided patch units are sequentially and regularly coded, and a subdivision network suitable for efficient organization of spatial information is constructed, so that the quadtree subdivision of the whole degree, the whole minute and the whole second is realized, and a multi-scale quadtree grid of a bin (32 levels) as large as the earth and as small as centimeter levels is formed; thus, in theory any aerospace object can be aggregated with corresponding voxels or patches. The method comprises the following steps: the system comprises traditional earth surface information such as mapping, weather, ocean and remote sensing, and various three-dimensional space and sky information such as ocean (underwater) information, weather clouds, gravitational fields, electromagnetic fields and the like. ) In addition, based on the GeoSOT geospatial reference grid framework, a new identification method can be provided for the organization and management of moving targets under the air, the sky, the ground and the ground (water). As the GeoSOT space grid is full of the whole earth space, description, expression and display of moving targets in the earth space range can be realized only by endowing any moving target with space grid codes (with time attributes) at a certain moment. For each moving object, a (C, T, a) triple is used for description, where C is a set of voxels (patches) (C0C1, …, Cn), T records temporal attributes, and a is a set of basic attribute information (A0a1, …, An) of the object.

Unified association of air, space and ground data: based on the multi-scale characteristic of the GeoSOT grid, a unique grid code can be given to a space object with the size from the big size to the whole earth and the small size to the centimeter-level size, and the space information automatically forms logic association on the earth space by means of the codes.

Optionally, the broadcast message or dedicated message of the cell may send configuration information for power control for different heights and/or angles, where the specific values may be the same or different: for example, the power control formula for PUSCH finds the dimension that joins the height h and/or angle ag:

the enhancement is as follows:

Ppusch(i，j,q_dl) ═ f (time of resource, frequency domain of resource, height of resource);

or:

Ppusch’(i，j,q_dl) ═ f' (time of resource, frequency domain of resource, height of resource, angle of resource);

the power control objects comprise a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), a channel Sounding Reference Signal (SRS), a random access preamble RA preamble, a random access RA Msg3 and the like.

The power spectral density of the UE transmission (i.e., power per RB) is the open loop engineering point + dynamic power offset.

Wherein, the open-loop industrial control point is nominal power P0+ open-loop path loss compensation α x (PL).

The nominal power P0 is divided into a cell nominal power and a UE specific nominal power. The network semi-statically sets the nominal power P0_ PUSCH and P0_ PUCCH for different heights and/or angles for all UEs within the cell, which is broadcast by system messages;

in addition, each UE may have a terminal specific nominal power offset, which is configured to the UE by issuing values for different heights and/or angles through dedicated RRC signaling (e.g., p0-UE-PUSCH, p0-UE-PUCCH), which may be the same or different. The unit of P0_ UE _ PUSCH and P0_ UE _ PUCCH is dB, one offset for different UEs for system nominal power P0_ PUSCH and P0_ PUCCH.

The configuration of the P0_ PUSCH, sent to the UE for semi-persistently scheduled uplink transmissions of different heights and/or angles, may be the same in value and may be different (e.g., SPS-ConfigUL: P0-NominalPUSCH-Persistent).

The open-loop path loss compensation PL is based on the UE's path loss estimate for the downlink. And the UE carries out path loss estimation by measuring the downlink reference signal RSRP and subtracting the RS signal power corresponding to the known AP. The original transmit power of the RS signal for the known AP is broadcast in the system message.

For the PUCCH, since different PUCCH users are code division multiplexed, α is 1, which can better control interference between different PUCCH users.

The dynamic power offset consists of two parts, power adjustment Δ TF based on the modulation and coding strategy MCS and closed loop power control. The power adjustment Δ TF and closed loop power control configuration sent to the UE for different height and/or angle MCSs may be the same or different values.
