When a terminal Receives (RX) a symbol carried on a subband k from a base station through an antenna, the symbol is first subjected to signal processing by a shaping filter to obtain a processed signal, then a CP of the signal is removed, then the CP-removed signal is subjected to Fast Fourier Transform (FFT) according to a carrier interval k, and then Orthogonal Frequency Division Multiplexing (OFDM) detection is performed on the subband i of the FFT-signal-processed signal, so that the symbol carried on the subband k and sent by the antenna receiving base station is converted into a signal recognizable to the terminal.

The method for determining access network equipment provided by the embodiment of the invention is suitable for the communication system shown in fig. 2, and the communication system comprises the access network equipment 1, the access network equipment 2 and the terminal 3.
Illustratively, when the access network device 1 is a high-speed rail base station, the access network device 2 is a residential base station, and the terminal 3 is in an overlapping area between a coverage area of the high-speed rail base station and a coverage area of the residential base station, the terminal 3 may determine the accessible access network device by executing the method for determining the access network device according to the embodiment of the present invention, so as to prevent the terminal of the high-speed rail user from accessing a base station that provides services for a general residential and prevent the terminal of the general residential from accessing a base station that provides services for the high-speed rail user.
In the following, referring to the communication system shown in fig. 2, taking an access network device as a current base station as an example, a method for determining an access network device provided in the embodiment of the present invention is described.
As shown in fig. 3, the method for determining the access network device includes the following contents S11-S14:
and S11, the current base station acquires the moving speed of the terminal in the coverage area, the number of antennas of each base station accessible by the terminal and the operation parameters.
In an implementation manner, the terminal may periodically (e.g., every Transmission Time Interval (TTI)) acquire real-Time location information according to a Global Positioning System (GPS) or a BeiDou satellite navigation system (BDS), and determine a current moving speed according to location information corresponding to two adjacent Time instants. Then, the terminal encapsulates a rate identifier in a Physical Uplink Control Channel (PUCCH) signaling, so that the base station determines the current moving speed of the terminal by decoding the PUCCH signaling after receiving the PUCCH signaling sent by the terminal.
Illustratively, taking the position information as a GPS coordinate and the sampling period as a TTI as an example, the moving speed V of the terminal satisfies:

wherein, LaiIndicating longitude information of the current TTI acquisition, Lai-1Represents the last oneLongitude information collected by TTI, LOiIndicating latitude information, LO, of the current TTI acquisitioni-1Indicating latitude information acquired in the last TTI.
In one implementation, the number of antennas may be the number of Transmit and Receive (TR) components. The base station side adds the identifier corresponding to the TR number into the switching or reselection signaling, so that the terminal obtains the TR number corresponding to the base station by decoding the switching or reselection signaling acquired from the base station.
For example, the table of information collected by the terminal and related to the base station is shown in table 1, where the operating parameters include Reference Signal Receiving Power (RSRP) and a load ratio.
TABLE 1
Figure BDA0002765260300000061
Figure BDA0002765260300000071
And S12, the current base station determines the type of the access network equipment to which each base station belongs according to the number of the antennas of each base station.
And S13, the current base station determines the base station of the next hop according to the type, the moving speed and the operation parameters of the access network equipment to which each base station belongs.
S14, the current base station sends a cell switching command carrying the next hop base station to the terminal. The cell switching instruction is used for indicating the terminal to be switched from the current base station to the base station of the next hop, and the base station of the next hop provides service for the terminal.
In an implementation manner, when the current base station determines the base station of the next hop, the current base station may notify the base station of the next hop that the terminal is to be accessed, so that the base station of the next hop can perform handover preparation in advance, and user experience is ensured.
Note that, when it is determined that the current base station is the base station of the next hop, no action is performed.
Therefore, after the terminal receives the cell switching instruction, when the terminal of the high-speed railway user is in an overlapping area between the coverage area of the residential base station and the coverage area of the high-speed railway station, the terminal can be switched from the current access network device to the next access network device according to the received cell switching instruction, and the next access network device provides services for the terminal. Therefore, the problem of how to select the accessible base station when the terminal is located in the overlapping area of the coverage area of the residential base station and the coverage area of the high-speed base station is solved.
In an implementation manner, referring to fig. 3, as shown in fig. 4, S12 described above can be specifically realized by S120 described below.
And S120, the current base station inquires a pre-stored access network equipment type table according to the number of the antennas of each base station, and determines the access network equipment type corresponding to each base station. The access network equipment type table meets the corresponding relation between the number of the antennas and the type of the access network equipment, and the type of the access network equipment comprises a low antenna number set and a high antenna number set.
In one implementation, an Active Antenna Unit (AAU) of a base station (e.g., 64TR, 32TR) in a high Antenna number set uses multiple arrays, e.g., 192 arrays for complex shaping operations to allocate a relatively independent interference-free channel to each user's terminal. When the terminal of the user is in a high-speed motion state, the time for the base station to perform calculation is increased when the base station receives the information fed back by the terminal, so that the base station in the high antenna number set does not have enough time to perform calculation, and the performance is reduced. However, the base station in the low antenna number set generally uses one beam direction already fixedly, and does not need to perform shaping calculation, so that the base station can be suitable for being used in a high-speed scene. Therefore, the method for determining the access network device provided by the embodiment of the disclosure classifies the base stations accessible to the terminal, so that when the moving rate of the terminal is greater than the rate threshold, the terminal is ensured to always search for a proper base station in a low antenna number set, and the user experience is ensured.
Illustratively, the access network device class table is shown in table 2.
TABLE 2
Access network device classes Number of TR Description of the use
Low antenna number set 2TR, 4TR and 8TR For high speed scene usage
High antenna number set 32TR、64TR For low speed scene usage
In another implementation manner, when the base station determines that the number of antennas is greater than the preset number of antennas, it determines that the base station belongs to the high-number-of-antennas set. Or when the base station determines that the number of the antennas is less than or equal to the preset number of the antennas, determining that the base station belongs to the low-number-of-antennas set.
In a practical manner, the access network device category includes a low antenna number set, and the operation parameter includes RSRP, in which case, as shown in fig. 4 in conjunction with fig. 3, the above S13 can be implemented by the following S130.
And S130, under the condition that the moving speed is greater than the speed threshold, the current base station determines that the base station with the RSRP meeting the first preset condition in the low antenna number set is the base station of the next hop.
In an implementable manner, a higher RSRP for a base station indicates a higher radio signal strength, so the terminal prioritizes the base stations with a high RSRP when accessing the base station. Therefore, the current base station determines the base station with the largest RSRP in the low antenna number set as the base station of the next hop.
Illustratively, taking the speed threshold as 80km/h as an example, in the case that the moving speed of the terminal is greater than 80km/h, the base station determines the base station with the maximum RSRP in the low antenna number set as the base station of the next hop.
In a practical manner, the access network equipment category includes a high antenna number set, and the operation parameters include RSRP and load rate, in which case, as shown in fig. 4 in conjunction with fig. 3, the above S13 can be implemented by the following S131.
S131, under the condition that the moving speed is smaller than or equal to the speed threshold, if a base station with the load rate smaller than the first threshold exists in the high antenna number set, the current base station determines that a base station with the load rate smaller than the first threshold in the high antenna number set meets a second preset condition as a next-hop base station.
In one achievable approach, the load ratio is equal to the ratio of the radio resources currently already occupied by the base station to the total radio resources of the base station.
In an achievable manner, the second preset condition is a maximum RSRP.
Illustratively, taking the speed threshold as 80km/h and the first threshold as 70%, in the case that the moving speed of the terminal is less than or equal to 80km/h, which indicates that the current moving speed of the terminal is low, a suitable base station can be selected in the high antenna count set. When base stations with the load rate lower than 70% exist in the high antenna number set, the base station with the maximum RSRP is preferentially selected from the base stations with the load rate lower than 70% to serve as the base station of the next hop, and therefore user experience is guaranteed.
Therefore, when the load rate of the base station is smaller than the first threshold, it indicates that the base station has more unoccupied radio resources, so that the terminal can be preferentially accessed to the base station having more unoccupied radio resources, thereby ensuring the utilization rate of the base station.
In a practical manner, the access network device category further includes a low antenna number set, in which case, as shown in fig. 4 in conjunction with fig. 3, the above S13 can be implemented by the following S132.
S132, if the moving speed is less than or equal to the speed threshold, if the load rate of each base station in the high antenna number set is greater than or equal to the first threshold, and the load rate of each base station in the low antenna number set is greater than or equal to the second threshold, the current base station determines that the access network device whose RSRP meets the second preset condition in the high antenna number set is the access network device of the next hop.
Illustratively, taking the speed threshold as 80km/h, the first threshold as 70% and the second threshold as 50%, in the case that the moving speed of the terminal is less than or equal to 80km/h, which indicates that the current moving speed of the terminal is low, a suitable base station may be selected in the high antenna number set. When the load rates of all base stations in the high antenna number set are all greater than 70% and the load rates of all base stations in the low antenna number set are all greater than 50%, the current base station determines that the base station with the largest RSRP in the high antenna number set is the base station of the next hop because the unoccupied radio resources in each base station accessible by the terminal are less.
As can be seen from the above, when the load rates of all the base stations in the high antenna number set are greater than the first threshold, and the load rates of all the base stations in the low antenna number set are greater than the second threshold, it is indicated that the unoccupied radio resources in each base station accessible to the terminal are less. And because the current moving speed of the terminal is less than or equal to the speed threshold, when the base station in the high antenna number set provides service for the terminal, the service quality of the terminal can be better ensured. Therefore, the base station with the largest RSRP in the high antenna number set can be selected as the base station of the next hop, and therefore the user experience is guaranteed.
In a practical manner, the access network device category further includes a low antenna number set, in which case, as shown in fig. 4 in conjunction with fig. 3, the above S13 can be implemented by the following S133.
S133, if the moving speed is less than or equal to the speed threshold, if the load ratio of each base station in the high antenna number set is greater than or equal to the first threshold and there is a base station whose load ratio is less than the second threshold in the low antenna number set, the current base station determines that a base station whose RSRP meets a second preset condition in base stations whose load ratios in the low antenna number set are less than the second threshold is a base station of the next hop.
Illustratively, taking the speed threshold as 80km/h, the first threshold as 70% and the second threshold as 50%, in the case that the moving speed of the terminal is less than or equal to 80km/h, which indicates that the current moving speed of the terminal is low, a suitable base station may be selected in the high antenna number set. When the load rates of all the base stations in the high antenna number set are greater than 70%, and the base stations with the load rates less than or equal to 50% exist in the low antenna number set, the unoccupied wireless resources in each base station in the high antenna number set are less, but the unoccupied base stations with more wireless resources exist in the low antenna number set. Therefore, the base station with the largest RSRP in the low antenna number set can be selected as the base station of the next hop.
As can be seen from the above, when the load ratios of all the base stations in the high antenna number set are greater than the first threshold, and there is a base station in the low antenna number set whose load ratio is greater than the second threshold, it is indicated that the unoccupied radio resources in each base station accessible in the high antenna number set are less. And because the current moving speed of the terminal is less than or equal to the speed threshold, when the base station in the high antenna number set provides service for the terminal, the service quality of the terminal can be better ensured. However, the base stations with more unoccupied wireless resources exist in the low antenna number set, and the base station with the largest RSRP in the low antenna number set can be selected as the base station of the next hop in order to prevent resource waste, so that the user experience is ensured.
