Detailed Description
The present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention.
It should be further noted that, for the convenience of description, only some but not all of the relevant elements of the present invention are shown in the drawings. Before discussing exemplary embodiments in greater detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a channel determination method according to an embodiment of the present invention, where this embodiment is applicable to a case where a terminal determines a receiving channel of a base station according to received channel identification information, and the method may be executed by a channel determination device, which may be implemented by software and/or hardware, and may be generally integrated in a terminal and used in cooperation with a base station for sending channel identification information. Accordingly, as shown in fig. 1, the method comprises the following operations:
s110, acquiring the channel identification information sent by the base station.
The channel identification information may be identification information generated by the base station according to the associated data of the base station, and is used to identify an available receiving channel.
When a terminal and a base station perform uplink communication, the problem of fixed interference is often encountered. The fixed interference means that a certain frequency point can be continuously interfered by other fixed frequency points, the fixed interference can reduce the communication quality of a receiving channel corresponding to the interfered frequency point, and the problem of incapability of communication can be caused when the communication quality is serious. Therefore, in order to solve the fixed interference problem, the terminal can randomly frequency hop and select a receiving channel within the frequency range allowed by the base station.
In the embodiment of the present invention, the terminal may receive the channel identifier information sent by the base station, so as to determine the available receiving channel of the base station according to the channel identifier information.
In an optional embodiment of the present invention, the channel identification information may include at least: random number sequence identification, channel set identification, receiving channel number and random arrays; wherein, the number of the random numbers included in the random array is the same as the number of the receiving channels.
The random number sequence identifier is used for identifying a random sequence, and the random number sequence used by the base station can be determined from the random number sequence pool according to the random number sequence identifier. The channel set identification may be used to identify a set of channels used by the base station, which may be a set of receive channels usable by the base station. The number of receiving channels may be the maximum number of simultaneous receiving channels of the base station, and the random number group may be a group consisting of a set number of random numbers designated by the base station.
In the embodiment of the present invention, each base station may correspond to one channel set, and the base station may arbitrarily select a reception channel in the channel set to receive the communication data sent by the terminal. The channel set may be a set of consecutive frequency points in a certain frequency domain. At the same time, the hardware capabilities of each base station may limit the maximum number of simultaneous receive channels. Therefore, the base station may generate the channel identification information by using a random number to instruct the terminal to determine the receiving channel of the base station in a manner of implementing random frequency hopping according to the random number.
TABLE 1Beacon information List
| RandomSeqInd | Random number sequence identification |
| ChannelGroupInd | Channel set identification, taking the value of [0, N/M-1] |
| BSId | Base station ID |
| FrameNum | Time frame number |
| ChannelNum | Number of receiving channels |
| Radom[ChannelNum] | Random array |
Alternatively, the base station may use Beacon (Beacon) information as the channel identification information. Table 1 is a list of Beacon information provided in an embodiment of the present invention, and in a specific example, data contents included in the Beacon information are as shown in table 1. Besides the channel identification information based on the random number sequence identification, the channel set identification, the number of the receiving channels, the random number group and the like, the base station ID and the time frame number can be additionally added as the channel identification information. The embodiment of the present invention does not limit the data type and content included in the channel identification information.
Correspondingly, the base station can indicate the terminal under the base station to realize frequency hopping synchronization with the base station through broadcasting Beacon information. Before broadcasting Beacon information, a base station needs to determine a random number sequence and a channel set used by the base station. Optionally, each base station may cooperatively process the random number and the channel set through the same rule, and determine the random number sequence and the channel set used by itself, for example, each base station may communicate with each other to inform the selected random number sequence and channel set. Or, the base station may further obtain the random number sequence and the channel set through configuration information of the system, where the system may be a system that manages each base station, and may also be configured through a remote server to obtain the random number sequence and the channel set, which is not limited in this embodiment of the present invention. The number of the received channel data in the Beacon information list is the same as the number of the random numbers in the random array. After the channel set is determined, the channel set identifier can be obtained. The number of receiving channels needs to be determined according to the capability of the base station to receive the channels at the maximum, for example, the number of channels that the base station can receive at the maximum at the same time is 8, and the number of receiving channels may be 8. Meanwhile, the base station may generate random numbers of the number of the receiving channels, and form a random array according to the random numbers of the number of the receiving channels. It should be noted that the random number in the random number group may be a random number with any value, and the value range of the random number in the random number group is not limited in the embodiment of the present invention.
And S120, determining the position of the channel random number and the random number sequence according to the channel identification information.
The channel random number position may be a position for searching for a corresponding random number in a random number sequence, and may also be referred to as a random number sequence number.
Correspondingly, after receiving the channel identification information, the terminal can determine the channel random number position and the random number sequence according to the channel identification information.
In an optional embodiment of the present invention, the determining the channel random number position and the random number sequence according to the channel identification information may include: sequentially traversing the random arrays, and determining the current random number from the random arrays; calculating the channel random number position according to the current random number; and determining the random number sequence according to the random number sequence identification and a random number sequence pool.
Wherein, the current random number may be a random number currently being processed in the random array. The pool of random number sequences may include a large number of random number sequences.
Specifically, after receiving the channel identification information, the terminal may sequentially traverse the random arrays in the channel identification information, determine a current random number from the random arrays, and calculate a channel random number position according to the current random number. Each random number in the random number group can correspondingly calculate a channel random number position, and each channel random number position can determine a unique random number from the random number sequence. Meanwhile, the terminal can also determine the random number sequence according to the random number sequence identification and the random number sequence pool. It should be noted that, before the terminal and the base station communicate, each base station and the terminal may first configure the same random number sequence pool.
Fig. 2 is a schematic diagram illustrating an effect of a random number sequence pool according to an embodiment of the present invention. As shown in fig. 2, the random number sequence pool may include a large number of randomly generated random number sequences, each random number sequence may include a certain number of random numbers, and the random numbers included in each random number sequence are different from each other. Table 2 is a random number distribution list of a random number sequence according to an embodiment of the present invention. In one specific example, as shown in Table 2, the random number sequence may be an array sample [256] of length 256. The elements in the array are random numbers which are randomly generated and are unique and not repeated, and the value range of the random numbers is {0,1,2, \8230;, 255}.
TABLE 2 random number distribution List of random number sequences
It should be noted that the random number sequence pool may be generated in advance, the number of the random number sequences included in the random number sequence pool may be any number, and optionally, the number of the random number sequences may be greater than or equal to the number of the base stations. The embodiment of the invention does not limit the generation mode of the random number sequence pool and the number of the random number sequences included in the random number sequence pool.
S130, determining a receiving channel of the base station according to the channel random number position and the random number sequence.
Correspondingly, after the terminal determines the channel random number position and the random number sequence, the receiving channel of the base station can be determined according to the channel random number position and the random number sequence. Therefore, the terminal can realize synchronous frequency hopping operation with the base station by using the random number data in the channel identification information, so that an available receiving channel of the base station is determined, the base station is prevented from always adopting a fixed receiving channel to carry out uplink communication with the terminal, the problem of fixed interference is effectively avoided, and the uplink communication quality between the base station and the terminal is improved.
In an optional embodiment of the present invention, the determining a receiving channel of the base station according to the channel random number position and the random number sequence may include: determining a target receiving channel set matched with the base station according to the channel set identifier; determining a random number at the channel random number position in the random number sequence as a target random number; performing modular operation on the target random number and the frequency hopping width of the base station to obtain receiving channel offset; determining the receiving channel according to the receiving channel offset and the target receiving channel set.
The target receiving channel set may be a set formed by partial receiving channels available to the base station, and the target receiving channel set corresponding to each base station may be the same or different. The target random number may be a random number determined from the random number sequence and the channel random number position. The base station frequency hopping width may be the frequency domain width supported by the base station's hardware, which may determine the range of receive channels available to the base station. The receive channel offset may be an offset of the target set of receive channels.
Specifically, the terminal may determine a target receiving channel set matched with the base station according to the channel set identifier, and determine a target random number from the random number sequence according to a channel random number position calculated by each random number in the random number set. Further, the terminal may perform modulo operation on the obtained target random number and the frequency hopping width of the base station, so as to obtain the receiving channel offset in the target receiving channel set. After the receiving channel offset is obtained, the available receiving channel of the base station can be determined from the target receiving channel set according to the receiving channel offset.
Illustratively, the terminal acquires a random number R = Radom [ index ] in a random array in the Beacon information, where the index represents a position of an element in the random array, and calculates P = R modulo Q according to the acquired random number, and P represents a random number sequence number in the random number sequence. Optionally, the value of Q may be 256, or may also be other values, and the embodiment of the present invention does not limit the specific value of Q. After P is obtained, the position of the sequence number P may be searched in the random number sequence, and the value S of the random number corresponding to the position is obtained, where S = sample [ P ]. Further, the terminal calculates a receiving channel of the base station according to S, and may calculate a value of C according to C = S modulo M. Correspondingly, after obtaining C, the terminal may search the C-th channel in the target channel set of the base station, and use the C-th channel as the index-th receiving channel of the base station in the beacon period. And the terminal determines the channeliNum receiving channels which can be used in the beacon period in sequence.
Table 3 is a Beacon information list of a base station according to an embodiment of the present invention, and in a specific example, as shown in table 3, it is assumed that a random number sequence is identified as 1, a channel set is also identified as 1, and the number of receiving channels is 4, which indicates that the base station can support 4 receiving channels at the maximum, so that the random number group includes 4 random numbers, which are 32, 245, 321, and 492 respectively. Correspondingly, after receiving the Beacon information, the terminal determines a random number sequence and a target channel set used by the base station. Assuming that the total number of channels available to each base station is 96 and the frequency hopping width M =16 supported by hardware of each base station, the total number of receiving channels available to the base station can be divided into 6 channel sets. The channel set identifier of the first channel set is 0, the included receiving channel range is channels [ 0-15 ], the channel set identifier of the second channel set is 1, the included receiving channel range is channels [ 16-31 ], and so on, the channel set identifiers of other channel sets and the included receiving channel range can be obtained. Specifically, the terminal determines that the base station uses the first random number sequence in the random number sequence pool according to RandomSeqInd =1, determines that the channel set identifier of the target channel set used by the base station is 1 according to the channegrroupin =1, and may determine that the target channel set of the base station is a channel [ 16-31 ] according to the channel set identifier. The terminal obtains the first Random number from the Random number group, R = Random [0] =32, and continues to calculate P =32 modulo 256=32, that is, P =32. And the terminal searches a random number value at the 32 th position from the first random number sequence in the random number sequence pool, and assuming that the random number distribution of the first random number sequence is shown in table 2, the random number at the 32 th position is S =49. The calculation continues with C =49 modulo 16=1, i.e. C =1. The terminal determines the first receiving channel of the base station as channel 17 among channels 16 to 31 in channel set 1.
Accordingly, the terminal determines the second receiving channel of the base station according to the above logic, and calculates R = Random [1] =245, p =245 modulo 256=245. The random number value for the 245 th position found from the first random number sequence in the random number sequence pool is S =156, c =156 modulo 16=12. The terminal determines the second receiving channel of the base station as channel [28] among channels [16 to 31] in channel set 1. Similarly, the terminal may determine the third receiving channel and the fourth receiving channel of the base station in turn according to 321 and 492 in the random number value.

The embodiment of the invention determines the position of the channel random number and the random number sequence according to the received channel identification information through the terminal, and determines the receiving channel of the base station according to the position of the channel random number and the random number sequence, thereby solving the problem that the uplink communication between the existing base station and the terminal is easy to be subjected to fixed interference, and improving the uplink communication quality between the base station and the terminal.
Example two
Fig. 3 is a flowchart of a channel determination method according to a second embodiment of the present invention, where this embodiment is applicable to a case where a base station generates channel identification information to send to a terminal, so that the terminal determines a receiving channel of the base station, and the method may be executed by a channel determination device, which may be implemented by software and/or hardware, and may be generally integrated in a base station and used in cooperation with the terminal for determining a receiving channel of the base station. Accordingly, as shown in fig. 3, the method includes the following operations:
s210, obtaining the base station associated data.
The base station related data may be related data used by the base station to generate the channel identification information.
In the embodiment of the present invention, the base station needs to acquire the base station association data to generate the channel set identification information.
In an optional embodiment of the present invention, the acquiring the base station association data may include: acquiring a target channel set identifier; under the condition that the target channel set identifier is not used by the associated base station, randomly selecting a random number sequence from a random number sequence pool, and generating a random number sequence identifier according to the random number sequence; determining the number of receiving channels according to the hardware attribute data of the base station; randomly generating random arrays with set number in a preset array range; wherein the set number is the same as the number of the receiving channels.
The target channel set identifier may be a channel set identifier corresponding to a target channel set used by the base station. The associated base station may be another base station. The base station hardware attribute data may be attribute data of base station related hardware, such as the number of maximum receiving channels that the base station can support simultaneously.
It should be noted that, the base station may obtain the base station related data through the system, may also obtain the base station related data through the remote server, or may also determine the base station related data in cooperation with other base stations themselves.
For example, the base station may obtain the target channel set identifier according to the configuration information of the system, may also directly determine the target channel set identifier itself, and may also obtain the target channel set identifier through the remote server. It should be noted that, if the base station needs to directly determine the target channel set identifier, in order to avoid the uplink collision problem, a multi-base station collision avoidance mechanism needs to be used for performing cooperative processing between the base stations. Meanwhile, when the base station acquires the target channel set identifier from the system or the remote server, the system and the remote server also need to allocate a corresponding channel set to each base station through a multi-base station collision avoidance mechanism.
Fig. 4 is a schematic diagram illustrating an effect of a multi-base station collision avoidance mechanism according to a second embodiment of the present invention. In a specific example, the principle of the multi-base station collision avoidance mechanism is described with reference to fig. 4. Assume that there are 3 channel sets in common, channel set 1, channel set 2, and channel set 3. If the number of base stations is less than or equal to the number of channel sets, indicating that each base station can implement isolation in the frequency domain, different channel sets may be allocated to each base station. For example, different channel sets are assigned to base station a, base station B, and base station C, respectively. Accordingly, each base station can identify the channel set that it can use using a different channel set identifier. If the number of base stations is greater than the number of channel sets, which indicates that it is impossible to implement isolation of all base stations in the frequency domain, some different base stations may need to be allocated the same channel set. For example, channel set 1 is used for both base station a and base station D.
Correspondingly, if the base station determines that the target channel set identifier is not used by other associated base stations, that is, the target channel set corresponding to the target channel set identifier is used by the base station alone, the base station and other base stations have uplink collision problems. At this time, the base station may directly randomly select one random number sequence from the random number sequence pool, and generate a corresponding random number sequence identifier according to the selected random number sequence. Meanwhile, the base station can also determine the number of receiving channels according to the hardware attribute data of the base station, and randomly generate random arrays with set number in the range of the preset arrays. Since the random number group is used to determine the receiving channels of the base station, it is necessary to ensure that the set number is the same as the number of receiving channels.
And S220, generating channel identification information according to the base station associated data.
In an optional embodiment of the present invention, the generating channel identification information according to the base station association data may include: and generating the channel identification information according to the random number sequence identification, the channel set identification, the receiving channel number and the random number group.
Correspondingly, after the information is determined, the base station can generate channel identification information according to the random number sequence identification, the channel set identification, the receiving channel number and the random number group. In addition, the base station may also add a base station ID, a time frame number, and the like as the channel identification information, and the embodiment of the present invention does not limit the specific content of the channel identification information.
In an optional embodiment of the present invention, the acquiring the target channel set identifier may include: acquiring a channel set determined according to the frequency hopping width of a base station and a base station receiving channel set; wherein each channel set in the channel set corresponds to one channel set identifier; selecting, from the set of channel sets, a set of channels not used by an associated base station as a target set of channels; and acquiring the channel set identifier of the target channel set as the target channel set identifier.
Wherein, the base station receiving channel set can be the total set of the receiving channels available for each base station. The channel set may be a set of channel sets.
It should be noted that although a large number of receiving channels may be allocated to the base station for the base station to use, the base station is limited by the hardware capability, and a single base station cannot perform frequency hopping to switch the receiving channels in the full frequency band, but can only switch the receiving channels within a certain range. Therefore, it is necessary to divide the channel sets that can be supported by multiple base stations according to the frequency hopping widths of the base stations on the basis of the channel sets received by the base stations. Accordingly, the base station may select a channel set that is not used by the associated base station from the channel set as a target channel set, and acquire a channel set identifier of the target channel set as a target channel set identifier.
Fig. 5 is a schematic diagram illustrating an effect of dividing a channel set based on a base station receiving channel set according to a second embodiment of the present invention. In a specific example, as shown in fig. 5, assuming that the frequency hopping width of the base station supported by the base station is M channel widths, one channel set may be set to include M channels. If the base station reception channel set includes N channels in total, the number of the channel set is N/M. If the value of N/M is non-integer, then rounding up may be performed and the number of last channel sets may be less than M. Each channel set does not coincide with each other. Correspondingly, the mapping relationship between the channel set identifier and each channel is shown in table 4, wherein channel set 0, channel set 1 \8230 \\8230indicatesthe channel set identifier. As shown in Table 4, the M channels in the channel set may each be numbered in a 0-M-1 manner to identify each channel. For example, assuming N +96,m =16, the channel set may include 6 channel sets in total, and each channel set may correspond to a unique channel set identifier. Channel set 0 includes receiving channels ranging from channel [ 0-15 ], channel set 1 includes receiving channels ranging from channel [ 16-31 ], and so on.
Table 4 list of mapping relationships between channel set identities and channels
| Intra-set channel numbering | Channel set 0 | Channel set 1 | … |
| 0 | Channel 0 | Channel M | … |
| 1 | Channel 1 | Channel M+1 | … |
| 2 | Channel 2 | Channel M+2 | … |
| 3 | Channel 3 | Channel M+3 | … |
| … | … | … | … |
| M-1 | Channel M-1 | Channel 2M-1 | … |
In an optional embodiment of the present invention, the channel determining method may further include: determining an associated random number sequence of an associated base station using the target channel set identification, in the event that the target channel set identification is determined to be used by the associated base station; deleting the associated random number sequence from the random number sequence pool to obtain a residual random number sequence; and randomly selecting a random number sequence from the residual random number sequences, and generating a random number sequence identifier according to the random number sequence.
Wherein the associated random number sequence may be a random number sequence used by the associated base station. The remaining random number sequence may be a random number sequence obtained by deleting the associated random number sequence from the pool of random number sequences.
Accordingly, if the base station determines that each channel set identifier is used by the associated base station, it indicates that the number of base stations is greater than the number of channel sets. At this time, the base station may select a target channel set identifier from the channel set identifiers, for example, select the channel set with the fewest associated base stations as the target channel set. At this time, in order to avoid the uplink collision problem of different base stations in the same channel set, the base station may determine the associated random number sequence of the associated base station using the target channel set identifier, and delete the associated random number sequences used by other associated base stations from the random number sequence pool to obtain the remaining random number sequence. The residual random number sequence is not used by the associated base station, so that the receiving channel determined according to the residual random number sequence cannot be repeated with the receiving channel determined by the associated base station, and the problem of uplink collision among the base stations is avoided.
