User equipment first has to send preamble data during random access to may include as shown in Figure 2 b following Ring prefix (CP), access lead code sequence, protection interval (GT)；Access network equipment can receive user equipment for the more of broadcast Preamble data transmitted by a synchronized broadcast block.It should be noted that can be prestored in user equipment synchronized broadcast block with The mapping relations of preamble data set, can be for the synchronized broadcast block received, in corresponding preamble data set Randomly select the transmission of some preamble data uplink.The main function of preamble data is to inform that access network equipment has a use The random access request of family equipment, and access network equipment is enabled to estimate its propagation delay time between user equipment so as to high-ranking officers Calibration information informs user equipment, to carry out uplink synchronous；And in the present embodiment, the effect of preamble data also resides in can Characterization and user equipment the synchronized broadcast block transmitted by the nearest far-end unit, so as to realize user equipment of adjusting the distance The positioning function of user equipment is realized in the positioning of nearest far-end unit.

It is understood that user equipment can be in the frequency range of agreement, upper primary communications band or other default frequencies Cell searching is carried out in section can choose signal quality most when user equipment receives multiple SSB that access network equipment issues Good SSB, and according in SSB PSS signal and SSS signal and access network equipment establish down-going synchronous, i.e., user equipment and connect Log equipment realizes frame synchronization, so as to be resolved to PBCH signal from SSB, and obtains above-mentioned synchronize extensively according to PBCH signal The second mapping relations of block and preamble resource are broadcast, so as to determine the best SSB of signal quality according to the second mapping relations At least one corresponding preamble resource, and a preamble resource is chosen from least one preamble resource, in selection The lead code in the preamble resource of selection is sent on the running time-frequency resource position of random access channel in preamble resource.

Illustratively, MIB message (Master Information Block, main system mould are carried in PBCH signal Block), user equipment can obtain PDCCH (Physical Downlink Control Channel, under physics by parsing MIB Row control channel) running time-frequency resource position, and then get PDCCH signal on the running time-frequency resource position of PDCCH, further may be used To obtain PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) in PDCCH signal Running time-frequency resource position, so that PDSCH signal is got on the running time-frequency resource position of PDSCH, it may further be in PDSCH signal Middle acquisition SIB1 information may include the second mapping relations of synchronized broadcast block and preamble resource in SIB1 information.It is exemplary Ground can also directly carry the second mapping relations of synchronized broadcast block and preamble resource in PBCH signal.

S203, access network equipment position user equipment according to random access configuration information and preamble data.

Illustratively, the preamble data that access network equipment is sent according to random access configuration information and user equipment, can To determine far-end unit corresponding to the preamble data of user equipment transmission, therefore can be using far-end unit as user equipment Position location.It is understood that the SSB of different far-end unit broadcast may be identical, it is thus possible to exist user equipment The case where navigating to multiple far-end units.

In the present embodiment, access network equipment passes through corresponding distal end according to preconfigured random access configuration information The corresponding synchronized broadcast block of cell broadcast, thus the signal quality that receives of the user equipment of each Idle state it is best synchronize it is wide Broadcasting block is usually to be sent by the far-end unit nearest apart from user equipment；Each user equipment can be in best same of signal quality It walks in the corresponding one of preamble resource of broadcast blocks, uploads preamble data to initiate random access；Access network equipment can To determine far-end unit associated by the preamble data of each user equipment transmission, this is remote according to random access configuration information End unit is apart from user equipment apart from nearest far-end unit, it is achieved that the positioning of the user equipment of each Idle state.

Referring to shown in Fig. 3, in one embodiment, it is related to the detailed process positioned to user equipment, may include:

S301, access network equipment parse the preamble data that user equipment is sent, obtain the corresponding lead code of user equipment Resource.

Illustratively, access network equipment, can be to leading yardage after the preamble data for receiving user equipment transmission According to being parsed, parsing obtains the corresponding preamble resource of user equipment；Before the preamble resource that the parsing obtains may include: Lead code in leading code data, and/or, carry the running time-frequency resource position of the random access channel of the preamble data.

S302, access network equipment determine that user sets according to the second mapping relations and the corresponding preamble resource of user equipment Synchronized broadcast block associated by standby corresponding preamble resource；And it is corresponding synchronous with user equipment according to the first mapping relations Broadcast blocks determine far-end unit associated by the corresponding synchronized broadcast block of user equipment.

Illustratively, as shown in table 1, the mapping relations and synchronized broadcast of far-end unit Yu synchronized broadcast block are shown The mapping relations of block and lead code.

When the corresponding lead code of user equipment A is p35, then the corresponding synchronized broadcast block of user equipment A is SSB3, synchronous The associated far-end unit of broadcast blocks SSB3 is DP1.

S303, position location of the access network equipment by the corresponding far-end unit of user equipment, as user equipment.

Illustratively, referring to above-mentioned example, access network equipment can be using far-end unit DP1 as the sprocket bit of user equipment It sets.

In a possible embodiment, access network equipment is broadcasted on the corresponding beam direction of each synchronized broadcast block Synchronized broadcast block；The then above-mentioned detailed process positioned to user equipment can also include: access network equipment according to preset Synchronized broadcast block synchronized broadcast block corresponding with the corresponding relationship of beam direction and user equipment determines that user equipment is corresponding same Walk beam direction associated by broadcast blocks；Correspondingly, S303 may include: that access network equipment is single by the corresponding distal end of user equipment Member and beam direction, the position location as user equipment.For example, the beam direction of synchronized broadcast block SSB3 be it is certain, far End unit DP1 is broadcasted on the beam direction of synchronized broadcast block SSB3, in this way, if the leading yardage that user equipment A is sent According to SSB3 to it is corresponding when user equipment very likely be located at broadcast SSB3 far-end unit DP1 near, and relative to The direction of DP1 is identical as the beam direction of synchronized broadcast block SSB3.It is single compared to the distal end for being only capable of navigating near user equipment For member, the direction of user equipment opposite proximal end unit can also be navigated to, therefore positioning accuracy is higher, be determined convenient for subsequent The high-quality signal transmission of point orientation.

Referring to shown in Fig. 4 a, in one embodiment, it is related to configuring the detailed process of random access configuration information, can wrap It includes:

S401, according to preset access network equipment Schema information, broadcast precision and configuration mode, determine needs access network equipment The number for the synchronized broadcast block to be configured；Broadcast the number that precision is synchronized broadcast block transmitted by each far-end unit；Configuration Whether the synchronized broadcast block that modeling is configured by each far-end unit is identical.

S402, the number for the synchronized broadcast block that access network equipment configures as needed, to the configuration of each far-end unit and extensively The corresponding synchronized broadcast block of precision is broadcast, the first mapping relations are obtained.

S403, access network equipment is according to preset preamble resource and the number of synchronized broadcast block needed to configure, to matching The each synchronized broadcast block set configures at least one preamble resource, obtains the second mapping relations.

In a kind of possible embodiment, access network equipment may include multiple expanding elements, access network equipment framework Information includes the number P of expanding element, and broadcast precision is M, and configuration mode is the first configuration mode, same under the first configuration mode The synchronized broadcast block that each far-end unit of a expanding element connection is configured is identical, then the number of the synchronized broadcast block needed to configure More than or equal to M × P；

Correspondingly, the number for the synchronized broadcast block that access network equipment configures as needed, to each far-end unit configuration with Broadcast the corresponding synchronized broadcast block of precision, comprising:

Access network equipment chooses the number phase with the synchronized broadcast block needed to configure from preset synchronized broadcast set of blocks The synchronized broadcast block of number is answered, and from the synchronized broadcast block of selection, each far-end unit connected to the same expanding element Configure identical M synchronized broadcast block.

It is understood that because the corresponding synchronized broadcast block of different expanding elements is different, but it is same expanding element Under the configuration of each far-end unit synchronized broadcast block it is identical, therefore multiple far-end units for being located under some expanding element For user terminal in overlay area, the far-end unit navigated to may have multiple and belong to the expanding element, that is to say, that Positioning accuracy is that user equipment is located near multiple far-end units under the expanding element.When in view of orientation, work as M=1 When, because direction is difficult to determine, positioning accuracy is basically unchanged without reference to object；When M >=2 when, positioning accuracy be the expansion It opens up on a certain determining direction in M direction of multiple far-end units under unit.

Referring to shown in Fig. 4 b, broadcast precision is 4, and configuration mode is the first configuration mode, then being expected positioning accuracy is user Equipment can be located on a certain determining direction in the four direction of multiple far-end units under CP；The number of the SSB needed to configure The CP number equal to 4 times is had to be larger than, it can be according to immediate one of the selectable value selection that 3GPP protocol specification provides.True After the number for determining SSB, by taking lead code number is 64 as an example, 64 random access lead code sequences (lead code) can be assigned to In each SSB.

For example, the SSB that three far-end units under expanding element a configure is SSB0, SSB2, SSB4, SSB6, extension is single The SSB of three far-end units configuration under first b is SSB1, SSB3, SSB5, SSB7；Illustratively, it is sent when user equipment When preamble data corresponds to SSB2, the wave of the SSB2 for three far-end units that user equipment is located under expanding element a can be determined On Shu Fangxiang.

In a kind of possible embodiment, access network equipment Schema information includes the number N of far-end unit, broadcasts precision For M, configuration mode is the second configuration mode, and the synchronized broadcast block that different far-end units are configured under the second configuration mode is different, The number of the synchronized broadcast block then needed to configure is greater than or equal to M × N；

Correspondingly, the number for the synchronized broadcast block that access network equipment configures as needed, to each far-end unit configuration with Broadcast the corresponding synchronized broadcast block of precision, comprising:

Access network equipment chooses the number phase with the synchronized broadcast block needed to configure from preset synchronized broadcast set of blocks The synchronized broadcast block of number is answered, and from the synchronized broadcast block of selection, the far-end unit of Xiang Butong configures different M and synchronizes extensively Broadcast block.

It is understood that the synchronized broadcast block for the configuration of different far-end units is different, therefore for being located at some distal end For user terminal near unit, positioning accuracy is that user equipment is located near the far-end unit.When in view of orientation, As M=1, because direction is difficult to determine, positioning accuracy is basically unchanged without reference to object；When M >=2 when, positioning accuracy For on a certain determining direction in M direction of the far-end unit.

Referring to shown in Fig. 4 c, broadcast precision is 1, and configuration mode is the second configuration mode, i.e., expected positioning accuracy user sets It is standby to be located under a certain DP；The number of the SSB needed to configure has to be larger than equal to DP number, can be mentioned according to 3GPP protocol specification Immediate one of the selectable value selection of confession.After determining the number of SSB, 64 random access lead code sequences are also correspondingly equal It assigns in each SSB.

For example, the SSB that three far-end units 1~3 under expanding element a configure is respectively SSB0, SSB1, SSB2, extension The SSB of three far-end units 7~9 configuration under unit b is respectively SSB3, SSB4, SSB5；Illustratively, when user equipment is sent out When the preamble data sent corresponds to SSB2, it can determine that user equipment is located at far-end unit 3.

Referring to shown in Fig. 4 d, broadcast precision is 4, and configuration mode is the second configuration mode, i.e., expected positioning accuracy is user Equipment can be located on a certain determining direction in the four direction under a certain DP；The SSB number needed to configure has to be larger than equal to 4 DP number again, can be according to immediate one of the selectable value selection that 3GPP protocol specification provides.After determining SSB number, 64 random access lead code sequences are also correspondingly assigned in each SSB.

It, can be with when the preamble data that user equipment is sent corresponds to SSB2 for example, configuration schematic diagram as shown in figure 4d Determine that user equipment is located on the beam direction of the SSB2 of far-end unit 3.

In this application, the configuration mode of SSB is configured for each far-end unit, and is provided for each SSB configuring preamble code The mode in source can be the various configurations modes such as uniform configuration, random arrangement, however it is not limited to manner described above, it is only necessary to protect Each far-end unit is demonstrate,proved configured at least one synchronized broadcast block, each synchronized broadcast block is configured at least one preamble resource ?.

Optionally, access network equipment can according to need the number of the synchronized broadcast block of configuration and the power of each far-end unit Weight, to the synchronized broadcast block of each far-end unit configuration and the weight respective number of the far-end unit.It is understood that distal end The weight of unit is bigger, and the number of the synchronized broadcast block configured to the far-end unit is more.Illustratively, it is contemplated that there may be There are many inhomogenous situation of the distribution density of user equipment, such as the user equipment near the far-end unit in market, and User equipment near the far-end unit in park is less；It then can be by point of the user equipment of each far-end unit near zone Weight of the cloth density as each far-end unit, wherein the distribution density of user equipment can be preset；In this way, may be implemented SSB resource is distributed rationally, and positioning accuracy is improved.
