Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular to an information processing method, device and equipment. Background Art

[0002] In low-altitude flight scenarios, low-altitude coverage sites and ground coverage sites are networked in a 1:N co-site manner. Among them, the ground site PCI (physical cell identifier) ​​can be planned on the ground to avoid serious problems caused by PCI duplication or parameter duplication. However, in low-altitude coverage scenarios, affected by ray divergence, aerial ray coverage is layered, and different layers cover different cells and neighboring areas. If the ground PCI planning method is still used, long-distance cross-area coverage in the air and cloud reflections will cause more serious PCI conflicts and PCI confusion problems.

[0003] Specifically, PCI conflict means that the PCI of the local area and the neighboring area are the same, which affects the downlink synchronization and demodulation of the cell; PCI confusion means that the PCI of the neighboring area around the local area is the same, which affects the mobility of the terminal and may cause problems such as handover failure. In addition, the list of neighboring areas with ground coverage in the local area is relatively fixed, but the coverage of low-altitude cells changes with height, and the neighboring areas also change accordingly. At the same time, the higher the height, the greater the possibility of cross-area coverage, and the greater the probability of PCI conflict and confusion. The existing technology cannot determine the relevant information of PCI conflict and PCI confusion, which makes it impossible to perform related operations for technical optimization.

[0181] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0182] The present invention aims at the problem that the related information of PCI conflict and PCI confusion cannot be determined in the prior art, and provides an information processing method applied to a terminal, such as Figure 1 As shown, including:

[0183] Step 11: when it is determined that there are at least two base stations with the same physical cell identifier PCI, access a target base station among the at least two base stations;

[0184] Step 12: Send PCI-related information to the accessed target base station; wherein the PCI-related information is used to indicate the existence of PCI conflict and / or PCI confusion.

[0185] Among them, "accessing the target base station among the at least two base stations" may include: accessing according to the first rule, the first rule including: selecting different random access resources or different C-RNTIs of the same PCI (different base stations correspond to different C-RNTIs) to select the target base station for access, but not limited to this; PCI conflict means that the PCI of the base station accessed by the terminal is the same as that of the neighboring cell; PCI confusion means that the PCIs of the neighboring cells of the base station accessed by the terminal are the same.

[0186] The information processing method provided by the embodiment of the present invention accesses a target base station among the at least two base stations when it is determined that the physical cell identifiers PCIs of at least two base stations are the same; PCI-related information is sent to the accessed target base station; wherein the PCI-related information is used to indicate the existence of a PCI conflict and / or PCI confusion; and can support clarifying the relevant information of the PCI conflict and / or PCI confusion, and further support the target base station to determine the information of the base station where the PCI conflict and / or PCI confusion exists, thereby effectively solving the problem that the relevant information of the PCI conflict and PCI confusion cannot be determined in the prior art.

[0187] Among them, when it is determined that there are at least two base stations with the same physical cell identifier PCI, accessing the target base station among the at least two base stations includes: when it is determined that there are at least two base stations with the same PCI, sending preamble code information; receiving a random access response fed back by at least one of the base stations; according to the random access response, obtaining a timing advance TA value corresponding to the base station (i.e., the base station that sends the random access response); according to the TA value, accessing the target base station among the at least two base stations.

[0188] This allows accurate access to the target base station.

[0189] In an embodiment of the present invention, the receiving of a random access response fed back by at least one of the base stations includes: receiving random access responses fed back by at least two of the base stations; accessing a target base station among the at least two base stations according to the TA value includes: selecting a minimum value from the TA values ​​corresponding to each of the base stations; determining the base station corresponding to the minimum value as the target base station and accessing it.

[0190] In this way, it is possible to accurately access the target base station when the PCIs of multiple base stations are the same and the PRACH resources are the same. Specifically, it can be understood as selecting a base station for access according to different C-RNTIs corresponding to the (same) PCI (different base stations correspond to different C-RNTIs), and the C-RNTI corresponds to the TA value one by one. Among them, when there are at least two minimum values, it is possible to: randomly select a minimum value from them to determine the target base station, or select a minimum value from them according to a predetermined rule to determine the target base station, but it is not limited to this.

[0191] Among them, the sending of preamble code information when it is determined that there are at least two base stations with the same PCI includes: when it is determined that there are at least two base stations with the same PCI, according to the correspondence between PCI and different physical random access channel PRACH resources, sending preamble code information to a base station corresponding to the PRACH resource; wherein one PRACH resource corresponds to one base station; the receiving of a random access response fed back by at least one of the base stations includes: receiving a random access response fed back by the base station (i.e., the base station that receives the preamble code information) according to the preamble code information; before accessing the target base station among the at least two base stations according to the TA value, it also includes: accessing the base station that sends the random access response.

[0192] This can support operations for the case where the PCIs of multiple base stations are the same but the PRACH resources are different. Further, the solution may also include: determining the correspondence between the PCI and different PRACH resources according to the received synchronization signal block; but the present invention is not limited thereto.

[0193] In an embodiment of the present invention, accessing the target base station among the at least two base stations according to the TA value includes: when the accessed base station meets the first condition, taking the accessed base station as the target base station and maintaining access; or, performing at least one first operation until the accessed base station meets the first condition, taking the accessed base station as the target base station and maintaining access; wherein the first operation includes: when the accessed base station meets the second condition, according to the corresponding relationship, accessing another base station corresponding to the PRACH resource (which may be one other than the accessed PRACH resource); the first condition includes: the TA value corresponding to the base station is less than a first threshold, and the number of wireless link reports received for the base station is less than a second threshold; the second condition includes: the TA value corresponding to the base station is greater than or equal to the first threshold; or, the TA value corresponding to the base station is less than the first threshold, and the number of wireless link reports received for the base station is greater than or equal to the second threshold.

[0194] In this way, it can support accurate access to the target base station when the PCI of multiple base stations is the same but the PRACH resources are different. Specifically, it can be understood as selecting a base station for access based on different random access resources corresponding to the same PCI: when the base station initially accessed meets the first condition, the base station is maintained as the target base station for access; when the base station initially accessed does not meet the first condition, the accessed base station is replaced according to the corresponding relationship (that is, the base station corresponding to other PRACH resources is accessed) until the base station after the replacement meets the first condition, and the currently accessed (or finally accessed) base station is maintained as the target base station for access.

[0195] Among them, sending PCI-related information to the accessed target base station includes: sending PCI-related information to the accessed target base station through target resources; wherein the target resources include: the uplink resources of message 3 used for random access indicated in the random access response fed back by the target base station, or other uplink resources except the uplink resources of message 3.

[0196] This can support multiple ways of information transmission.

[0197] In an embodiment of the present invention, the PCI-related information includes at least one of the following: TA values ​​corresponding to other base stations among the at least two base stations except the target base station; the difference between the TA value corresponding to the target base station and the TA value corresponding to the other base stations; location information of the other base stations; the number of locations of the other base stations; the number of TA values ​​corresponding to the PCI; and the number of PRACH resources corresponding to the PCI.

[0198] This can support the target base station to accurately determine the information of the base station with PCI conflict and / or PCI confusion.

[0199] The embodiment of the present invention also provides an information processing method, which is applied to a target base station, such as Figure 2 As shown, including:

[0203] Furthermore, before receiving the PCI-related information sent by the terminal, it also includes: receiving the preamble information sent by the terminal; based on the preamble information, feeding back a random access response to the terminal; wherein the random access response carries the TA value corresponding to the target base station.

[0205] In the embodiment of the present invention, the information processing method further includes: after feeding back a random access response to the terminal according to the preamble information, establishing a connection with the terminal (ie, the terminal accesses the target base station).

[0206] This can support the terminal to accurately access the target base station.

[0207] Among them, the PCI-related information sent by the receiving terminal includes: PCI-related information sent by the receiving terminal through the target resources; wherein the target resources include: the uplink resources of message 3 used for random access indicated in the random access response fed back by the target base station, or other uplink resources except the uplink resources of message 3.

[0208] This can support multiple ways of information transmission.

[0209] In an embodiment of the present invention, the PCI-related information includes at least one of the following: TA values ​​corresponding to other base stations among the at least two base stations except the target base station; the difference between the TA value corresponding to the target base station and the TA value corresponding to the other base stations; location information of the other base stations; the number of locations of the other base stations; the number of TA values ​​corresponding to the PCI; and the number of PRACH resources corresponding to the PCI.

[0210] This can support the target base station to accurately determine the information of the base station with PCI conflict and / or PCI confusion.

[0211] It is noted here that the above-mentioned related contents on the terminal side and the target base station side can refer to each other, and the repeated contents will not be repeated.

[0212] The information processing method provided by the embodiment of the present invention is described below by way of example.

[0213] In response to the above technical problems, an embodiment of the present invention provides an information processing method, which can be specifically implemented as a solution for identifying PCI conflicts or PCI confusions, involving: the terminal feeds back random access information (corresponding to the above PCI-related information) upon access, informing the target base station (i.e. the accessed base station) that there are sites (i.e. base stations) around it with PCI conflicts or confusions, so as to support reporting to the system and inform the system that there is a PCI conflict or confusion at this location (the location corresponding to the target base station), and the system performs subsequent operations accordingly.

[0214] Specifically, Figure 3 As shown, when the user (ie, the terminal) is in a PCI conflict or confusion area (corresponding to a situation where the physical cell identifiers PCIs of at least two base stations are the same), the specific process of this solution (the number of base stations is 2 as an example) may include the following steps:

[0215] 1. The UE (terminal) searches the SSB (synchronization signal block) space to determine whether the PRACH resources of the two overlapping coverage cells (corresponding to the base station) are the same. If so, proceed to step 2; if not, proceed to step 3.

[0216] 2. For the case where the PCIs of the two base stations are the same and the PRACH resources are the same (specifically, the PCI, PRACH, paging and other resources in the conflicting or confusing area are exactly the same);

[0217] 1. The user sends a preamble, and the two cells (corresponding to the base station) reply with MSG2 respectively;

[0218] (1) The terminal sends a premble ID (corresponding to the preamble information), and the two base stations reply with random access responses RAR (i.e., message MSG2) respectively; corresponding to the above, when it is determined that there are at least two base stations with the same PCI, the preamble information is sent; and the random access responses fed back by at least two of the base stations are received;

[0219] Specifically: the terminal can (according to the RAR scrambling code) demodulate the physical downlink control channels PDCCH DCI (downlink control information) 1-0 of the two cells to determine the receiving position of the RAR (which can be the physical downlink shared channel PDSCH position), and receive the MSG2 (i.e., RAR message) of the two PDSCHs according to the receiving position; but this is not limited to this.

[0220] (2) The terminal demodulates two PDSCHs to obtain two sets of parameter information of MSG2, where the parameter information may include: timing advance TA (corresponding to the timing advance TA value corresponding to the base station obtained according to the random access response), cell radio network temporary identifier C-RNTI, physical uplink shared channel PUSCH resources of MSG3 (corresponding to the uplink resources of the above message 3) and Back off index.

[0221] 2. The terminal selects a cell with a smaller TA and uses the resources of the cell for access (corresponding to selecting the minimum value from the TA values ​​corresponding to the base stations; determining the base station corresponding to the minimum value as the target base station and accessing it), and this cell is the access cell (corresponding to the target base station);

[0222] The terminal selects the set of parameters for the smaller TA (indicating that the terminal is close to this base station) and initiates MSG3; specifically, MSG3 can be scrambled according to the C-RNTI corresponding to the selected TA and then sent; the accessed base station can successfully demodulate MSG3; among them, the C-RNTIs of the two base stations are inconsistent. After the target base station is accessed, the other base stations that overlap the cell will fail to access, that is, the terminal accesses the base station corresponding to the selected TA, and the other base station fails to access.

[0223] 3. The terminal replies to the access cell in MSG3, informing that there is a duplicate coverage cell in its coverage area; corresponding to the above-mentioned target resources, PCI-related information is sent to the accessed target base station; wherein the target resources include: the uplink resources of message 3 for random access indicated in the random access response fed back by the target base station.

[0224] Specifically, the terminal can report the TA value (corresponding to the TA value corresponding to the above-mentioned other base stations) or the TA difference (i.e., the TA difference between the current area and the neighboring area, corresponding to the difference between the TA value corresponding to the above-mentioned target base station and the TA value corresponding to the other base stations) of the neighboring area added to the current area (i.e., the area corresponding to the selected TA) in MSG3, and inform the serving cell that there is a PCI conflict and confusion in the area where the terminal is located. The current cell (i.e., the access cell) can obtain information (such as location) of the interfering neighboring area based on the TA difference.

[0225] 3. For the case where the PCI of two base stations is the same but the PRACH resources are different;

[0226] 1. A user uses a preamble to access a cell: the user sends a preamble to a cell, the cell replies with MSG2 (corresponding to the above random access response), and the user accesses the cell according to MSG2;

[0227] Specifically, the terminal may (determine and record according to the received SSB) the relationship between the PCI and the PRACH resource (corresponding to the correspondence between the above-mentioned PCI and different physical random access channel PRACH resources), and then distinguish the cells through the PRACH resources; then, the user adopts a premble access according to the recorded relationship, that is, accesses the cell corresponding to any one of the PRACH resources, that is, the terminal randomly selects a PRACH access (corresponding to the above-mentioned situation where it is determined that there are at least two base stations with the same PCI, according to the correspondence between the PCI and different physical random access channel PRACH resources, sending preamble information to a base station corresponding to the PRACH resource; wherein one PRACH resource corresponds to one base station; the receiving of the random access response fed back by at least one of the base stations includes: receiving the random access response fed back by the base station according to the preamble information; before accessing the target base station among the at least two base stations according to the TA value, it also includes: accessing the base station that sends the random access response);

[0228] Among them, the MSG2 replied by the accessed cell carries its corresponding TA; if the TA is large, or the TA is small and the terminal is subsequently frequently disconnected (i.e., a wireless link report is received), it means that this cell is an ultra-long coverage or reflection and refraction cell; it can be understood that the TA value corresponding to the above-mentioned base station is greater than or equal to the first threshold; or, the TA value corresponding to the base station is less than the first threshold, and a wireless link report is received for the base station, indicating that the base station is an ultra-long coverage or reflection and refraction base station.

[0229] 2. The user finally accesses a cell with a TA smaller than a certain value (corresponding to the first threshold above), avoiding ultra-long-distance coverage or cloud reflection;

[0230] Specifically, when the first cell is unstable (i.e., TA is large; or TA is small and wireless link reports are received multiple times), another PRACH resource is used for access next time (i.e., whether to change to another PRACH resource for access is determined based on the size of the TA and the wireless link report); corresponding to the above-mentioned situation where the accessed base station meets the second condition, access is made to another base station corresponding to the PRACH resource according to the corresponding relationship; the second condition includes: the TA value corresponding to the base station is greater than or equal to the first threshold; or, the TA value corresponding to the base station is less than the first threshold, and the number of wireless link reports received for the base station is greater than or equal to the second threshold.

[0231] 3. The terminal informs the access cell in MSG3 that there is an overlapping coverage cell in its coverage area; corresponding to the above-mentioned target resources, PCI-related information is sent to the accessed target base station; wherein the target resources include: the uplink resources of message 3 for random access indicated in the random access response fed back by the target base station.

[0232] Specifically, the terminal can add a new IE (element) in the MSG3 report sent to the target base station (i.e., the base station that has successfully accessed) to identify the number of different PRACH resources with the same PCI around the target base station (corresponding to the number of PRACH resources corresponding to the above PCI), and inform the serving cell (i.e., the target base station) that there are PCI conflicts and confusion problems in the area where the terminal is located.

[0233] Based on the above, the solution provided by the embodiment of the present invention includes the following contents:

[0234] 1. A solution for identifying PCI conflicts or PCI confusions, comprising: detecting and reporting, by a terminal, the number of PRACH resources corresponding to a PCI around a target base station or TA-related information (such as TA difference, TA number, etc.) corresponding to the same PRACH resource, and notifying the target base station of PCI conflicts and confusions near the target base station.

[0235] 2. The terminal selects different TA accesses for the same PRACH resource (corresponding to the above step 2), or different PRACH resource accesses (corresponding to the above step 3); according to the clear PCI-related information, the TA-related information (which may also be the location of the conflicting site determined according to the TA, etc.) or the number of conflicting sites near the target base station is informed on MSG3 or other uplink resources (corresponding to the above target resources).

[0236] Specific:

[0237] a) When the terminal obtains multiple TAs, it can inform the target base station of the location of the repeated coverage site;

[0238] And / or, b) when the terminal obtains multiple PRACH resources, the target base station may be informed of the number of repeated coverage sites (corresponding to the number of different PRACH resources).

[0239] In summary, the solution provided by the embodiment of the present invention can: select different random access resources (i.e., PRACH resources) or different C-RNTIs (corresponding to the above-mentioned TA) corresponding to the same PCI by the terminal to select a cell for access, thereby solving the problem of cell competition (caused by the same PCI) encountered by user access. Furthermore, it is also possible to: report the neighboring cell information of the same PCI (corresponding to the above-mentioned PCI-related information) by the terminal to notify the base station that there are conflicts and confusions in the area where the terminal is located, which will affect the network.
