Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for allocating antenna weights.
Background
With the rapid development of network communication technology, the popularization of internet and mobile communication equipment is gradually increased, and the informatization process of the society is accelerated continuously. With the help of the internet and mobile communication networks, people can conveniently and accurately transmit various information by using a communication signal system based on the communication network compared with traditional media such as newspapers, televisions and the like. The existing main stream communication signal system is usually based on the low frequency band of the 4G (fourth generation mobile communication technology) communication system or the high frequency band of the 5G (fifth generation mobile communication technology) communication system to transmit the communication signal.
In the existing 5G communication system, since the frequency band used by the communication signal is high, and the path loss during the high-frequency band transmission process is much larger than that of the low-frequency band of the 4G communication system, a large-scale antenna array is required for information transmission to reduce the path loss. And after the base station in the large-scale antenna array weights the downlink signal, a narrow beam aiming at User Equipment (UE) is formed, and the transmitted energy is aimed at a target user. Therefore, the communication system obtains higher antenna array gain to improve the receiving quality of signals, but the disadvantage is that the stronger the array gain is, the smaller the covered area is, which requires that the transceiving end can perform high-quality communication only by being aligned properly.
The current communication system can support the transmission of eight groups of communication signals at most, and the main transmission mode is to configure a fixed antenna weight for each group of communication signals to be transmitted and then transmit the communication signals with the fixed antenna weight. However, in an actual communication process, since each antenna weight (corresponding to one antenna) can only send one communication signal at a time, and since a position of a receiving side may change with a change of an environment, in order to improve communication quality, in the prior art, a spectrum resource of each antenna is usually increased to improve communication quality, so that a spectrum utilization rate of a base station is reduced.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of an antenna weight assignment method according to the present invention is shown, which may specifically include the following steps:
In the embodiment of the present invention, the communication signal to be sent and the number of groups of the communication signal to be sent can be determined according to the received user request or the communication requirement of the user. For example, the communication signal to be transmitted is synchronous broadcast information, and the current base station can transmit eight groups of synchronous broadcast information at most, and the corresponding group is SSB (SS/PBCH Block, synchronous signal and physical broadcast channel Block) 0-7; therefore, multiple sets of synchronized broadcast information to be transmitted and the number of sets can be determined from SSBs 0-7 according to communication requirements. For example, SSB0, SSB3, SSB4, and SSB5 are determined as the synchronized broadcast information to be transmitted, and the corresponding number of groups is 4.
And 102, when N is larger than 1, randomly selecting N antenna weight values from a preset antenna weight value set.
In the embodiment of the present invention, an antenna weight set is preset in a base station, and the antenna weight set may include a plurality of antenna weights.
In order to ensure that the number of the antenna weights is matched with the number of the groups of the communication signals to be sent, when the number N of the groups of the communication signals to be sent is greater than 1, the base station sends the communication signals to be sent by configuring the weights, and at this time, the N antenna weights can be arbitrarily selected from a preset antenna weight set.
For example, the N antenna weights may be selected sequentially, alternately or randomly, and the invention is not limited herein.
When the number N of groups of communication signals to be transmitted is not greater than 1, the base station transmits the communication signals to be transmitted by using a wide beam antenna, where the wide beam antenna is an antenna whose beam width is greater than that of the weight configuration.
103, distributing antenna weights for each group of communication signals to be sent by adopting the N antenna weights; wherein, each group of communication signals to be transmitted corresponds to an antenna weight.
In the embodiment of the present invention, the base station may directly adopt the N antenna weights, and may allocate one antenna weight to each group of communication signals to be transmitted; and then the base station can subsequently transmit the communication signals to be transmitted according to the antenna weight of each group of communication signals to be transmitted.
In the embodiment of the invention, a communication signal to be sent and the group number N of the communication signal to be sent are determined in the process of establishing a cell; when N is larger than 1, randomly selecting N antenna weights from a preset antenna weight set; and distributing one antenna weight for each group of communication signals to be sent by adopting the N antenna weights. Therefore, the weight value adopted by the communication signal to be sent can be flexibly configured according to different practical environments, the communication quality is improved, and the frequency spectrum utilization rate of the base station is also improved.
In the embodiment of the present invention, the cell establishment procedure may include cell parameter update and antenna weight update. Wherein, cell parameter updating can be performed first, and then antenna weight value updating can be performed; the antenna weight may be updated first, and then the cell parameter may be updated, which is not limited in the embodiment of the present invention.
In the following, the procedure of allocating the antenna weight is described by taking the cell parameter update first and then the antenna weight update as an example.
Referring to fig. 2, a flowchart of steps of an alternative embodiment of an antenna weight value allocation method according to the present invention is shown, which specifically includes the following steps:
The communication signal to be transmitted may include multiple types, such as synchronous broadcast information, channel state information, reference signals, and the like, and the embodiments of the present invention are not limited herein.
In a specific implementation, the communication signal to be sent may be sent by a signal sending block in the base station, so that after the communication signal to be sent, the signal sending block may be activated, so that the signal sending block can send the corresponding communication signal to be sent.
In a specific implementation, after an antenna weight equal to the number of communication information groups to be sent is selected from the antenna weight set through an Operation Management module (OM) of the base station, a cell parameter update message is generated and sent to the base station, so as to configure the antenna weight for the information to be sent of the base station subsequently.
Optionally, the antenna weight set may include multiple sets of weights, for example, a, B, C, D, E, F, G, H, and the like, which is not limited herein.
In the embodiment of the present invention, the base station receives the cell parameter update information sent by OM, and then may perform cell parameter update. In the cell parameter updating process, the signal index of the communication signal to be sent and the antenna weight index corresponding to the antenna weight can be determined from the cell parameter updating information.
Wherein, the signal index is used for uniquely identifying a communication signal to be sent; the antenna weight index is used for uniquely identifying the antenna weight; the signal index and the antenna weight index may be both numbers such as 1 or letters such as a, and the embodiments of the present invention are not limited herein.
In the embodiment of the present invention, in order to further improve the spectrum utilization rate in the antenna transmission process, whether the antenna weight index corresponding to the antenna weight is a subset of the signal index may be determined by comparing the signal index with the antenna weight index.
The cell parameter update information may include a check identifier of a communication signal to be sent; the check identity may be a default identity (which may be subsequently referred to as a second identity). After a base station sets a check mark, returning information to the OM; and the OM responds to the received check mark and issues antenna weight value updating information so as to complete subsequent antenna weight value updating.
In the embodiment of the invention, N groups of check marks corresponding to the communication signals to be sent are set according to a comparison result generated by comparing a signal index with an antenna weight index; and N groups of communication signals to be sent correspond to one check identifier.
Further, the sub-step 205 may comprise the sub-steps of:
in sub-step 2051, if the antenna weight index is a subset of the signal indexes, setting check identifiers corresponding to N groups of the communication signals to be sent as first identifiers.
In this embodiment of the present invention, if the comparison result shows that the antenna weight index is a subset of the signal index, the check identifier corresponding to the communication signal to be sent may be set as a first identifier, such as a digital identifier 1, a letter identifier X, and the like, which is not limited herein.
For example, if the antenna weight indexes are 2, 3, and 7, and the signal indexes are 2, 3, and 7, it is determined that the antenna weight indexes are subsets of the signal indexes, and at this time, the check flag may be set to 1; or, if the antenna weight indexes are a, c, and e, and the signal indexes are c, a, and e, determining that the antenna weight indexes are a subset of the signal indexes, and at this time, setting the check flag to X.
In sub-step 2052, if the antenna weight index is not the subset of the signal index, the check identifiers corresponding to the N groups of communication signals to be transmitted are set as second identifiers.
In this embodiment of the present invention, if the comparison result shows that the antenna weight index is not a subset of the signal index, the check identifier corresponding to the communication signal to be sent may be set as a second identifier, such as a digital identifier 0, a letter identifier Y, and the like, which is not limited herein.
For example, if the antenna weight indexes are 2, 4, and 7, and the signal indexes are 5, 3, and 7, it is determined that the antenna weight indexes are not the subset of the signal indexes, and at this time, the check flag may be set to 0; or, if the antenna weight indexes are b, c, a and the signal indexes are c, a, e, the antenna weight indexes are determined to be the subset of the signal indexes, and at this time, the check mark may be set to Y.
Optionally, the step 207 may comprise the sub-steps of:
substep 2071, when the check identifier corresponding to the N groups of communication signals to be transmitted is the first identifier, allocating the antenna weight to the communication signals to be transmitted according to a preset rule;
in the embodiment of the present invention, when OM determines that the check identifier is the first identifier, a first antenna weight update message is issued, where the first antenna weight update message may include a preset rule for allocating an antenna weight, and after receiving the antenna weight update message, the base station allocates an antenna weight for a communication signal to be sent according to the preset rule.
The specific allocation rule can be shown in table 1 below:
TABLE 1
Alternatively, the preset rule may be set according to different environments. As shown in table 1, the antenna weights corresponding to the antenna weight indexes 0 to 7 in the antenna weight set are a to G, a preset rule may be set to be configured randomly, if the signal indexes are 0, 3, 4, and 5, the determined antenna weight indexes are 0, 3, 4, and 5, and the antenna weights are a, D, E, and F, at this time, according to the preset random configuration rule, in the to-be-transmitted communication signal with the signal indexes of 0, 3, 4, and 5, the antenna weights D, E, a, and F with the antenna weight indexes of 3, 4, 0, and 5 are configured correspondingly, or the antenna weights F, a, D, and E with the antenna weight indexes of 5, 0, 3, and 4 are configured correspondingly; the embodiments of the invention are not limited thereto.
And substep 2072, when the check identifier corresponding to the N groups of communication signals to be transmitted is the second identifier, allocating the antenna weight according to the signal index.
In this embodiment of the present invention, when OM determines that the check identifier is the second identifier, it may be determined that an antenna weight cannot be allocated to the communication signal to be sent according to a preset rule because some factors, for example, an SSB beam scanning weight is not matched with an SSB parameter sent by a cell in a group, and then a second antenna weight update message is issued, where the second antenna weight update message may include determination information that the antenna weight is allocated according to a signal index, and after receiving the second antenna weight update message, the base station allocates, according to the signal index, an antenna weight that is consistent with the signal index to the communication signal to be sent, so as to ensure normal sending of the communication signal to be sent.
The specific distribution scheme can be as shown in table 2:
| SSB indexing | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | |
| Cell 0 | Whether SSB sends or not | 1 | 0 | 0 | 1 | 1 | 1 | 0 | 0 |
| Corresponding weight value | A | 0 | 0 | D | E | F | 0 | 0 | |
| Cell 1 | Whether SSB sends or not | 0 | 1 | 0 | 1 | 1 | 1 | 0 | 0 |
| Corresponding weight value | 0 | B | 0 | D | E | F | 0 | 0 | |
| Cell 2 | Whether SSB sends or not | 0 | 0 | 1 | 1 | 1 | 1 | 0 | 0 |
| Corresponding weight value | 0 | 0 | C | D | E | F | 0 | 0 |
TABLE 2
For example, if the signal index is 0, 3, 4, or 5, the antenna weights a, D, E, and F with antenna weight indexes of 0, 3, 4, or 5 are correspondingly allocated to the signal to be transmitted corresponding to the signal index.
Optionally, when the base station cannot allocate the weight in a preset allocation rule manner, the base station may further report an alarm and a cell establishment failure event to the OM, and display additional information of a failure reason, for example, "the SSB beam scanning weight is not matched with an SSB parameter sent by a cell in a group," which is not limited herein.
In the embodiment of the present invention, the Base station further includes a BBU (baseband processing Unit) and an AAU (Active Antenna Unit), and when an Antenna weight assignment process is completed, the Base station further includes sending an Antenna weight to the BBU and the AAU for physical layer (e.g., antenna) configuration, so that the Base station sends the communication signal to be sent through the configured Antenna weight.
And step 208, sending the communication signals to be sent according to the antenna weight of each group of communication signals to be sent.
In the embodiment of the present invention, after each group of communication signals to be sent is configured with an antenna weight, the configured antenna weight may be transmitted to the BBU and the AAU, and the BBU and the AAU configure physical layer devices by using the configured antenna weight, and then send multiple groups of communication signals to be sent according to the configured antenna weight.
In summary, in the embodiment of the present application, the number of groups of communication signals to be sent is determined, and the antenna weights corresponding to the number of groups are arbitrarily selected from the preset antenna weight set; executing a cell parameter updating process to compare the signal index with the antenna weight index, and setting a check mark of a communication signal to be sent according to a comparison result; executing an antenna weight updating process to determine different check marks, and configuring an antenna weight for a communication signal to be sent according to different check marks in different modes; and sending the communication signal to be sent according to the configured antenna weight. The problem that flexible configuration cannot be carried out aiming at different practical environments due to the fact that a sending mode of a fixed weight is single is solved, whether the configuration of the antenna weight is flexible configuration or fixed configuration can be determined according to different environments, and performance of a communication system and utilization rate of a base station frequency spectrum are improved.
Secondly, when the antenna weight index is determined not to be the subset of the signal index, the antenna weight distribution process can still be executed at the moment so as to ensure the normal sending of the communication signal; when the antenna weight index is determined to be the subset of the signal index, the effect of executing the antenna weight distribution process is optimal, and the performance of the communication system and the frequency spectrum utilization rate of the base station can be further improved.
In the following, the process of allocating the antenna weight is described by taking an example of updating the antenna weight and then updating the cell parameter.
Referring to fig. 3, a flowchart illustrating steps of an alternative embodiment of the antenna weight value allocation method according to the present invention is shown, in the embodiment of the present invention, an antenna weight value updating process is performed first, and then a cell parameter updating process is performed, which may specifically include the following steps:
Step 301 to step 302 are similar to step 201 to step 202 described above, and are not described herein again.
In the embodiment of the invention, the base station receives the antenna weight updating information issued by the OM, and the pre-distribution process of the antenna weight is executed when the selected antenna weight is consistent with the number of the communication signals to be sent. The N antenna weights may be respectively allocated to each group of communication signals to be transmitted, and the antenna weights allocated at this time and their antenna weight indexes are stored.
Further, step 305 may include the following sub-steps:
and a substep 3051, setting check identifiers corresponding to N groups of the communication signals to be transmitted as first identifiers if the antenna weight indexes are the subset of the signal indexes.
And a substep 3052, if the antenna weight index is not the subset of the signal index, setting the check identifiers corresponding to the N groups of communication signals to be transmitted as second identifiers.
Step 304-step 306 are similar to step 203-step 205, and are not described herein again.
And 307, distributing respective antenna weights to each group of communication signals to be transmitted according to the check identifier and the N antenna weights.
In the embodiment of the present application, in the process of step 303, a pre-allocation process of the antenna weight is already performed, and after the base station receives the cell parameter update information sent by the OM and sets the check identifier. At this time, the redistribution of the antenna weight values can be executed for each group of communication signals to be distributed according to the check mark and the distributed N antenna weight values. For example, in the pre-allocation process, the to-be-communicated signals with signal indexes of 0, 3, 5, and 6 are allocated with the antenna weights a, D, F, and G with antenna weight indexes of 0, 3, 5, and 6, and after the re-allocation process is performed, the to-be-communicated signals with signal indexes of 0, 3, 5, and 6 may be allocated with the antenna weights F, a, D, and G with antenna weight indexes of 5, 0, 3, and 6.
Optionally, at this time, the base station does not need to receive the antenna weight update information, and step 307 may include the following sub-steps:
in sub-step 3071, when the check identifier corresponding to the N groups of communication signals to be sent is the first identifier, the antenna weight is allocated to the communication signals to be sent according to a preset rule.
Substep 3072, when the check identifier corresponding to the N groups of communication signals to be transmitted is the second identifier, allocating the antenna weight according to the signal index.
Substeps 3071-3072 are similar to substeps 2071-2072 described above and will not be described in detail herein.
And 308, sending the communication signals to be sent according to the antenna weight of each group of communication signals to be sent.
Step 308 is similar to step 208 described above and will not be described again.
In summary, in the embodiment of the present application, the number of groups of communication signals to be sent is determined, and the antenna weights corresponding to the number of groups are arbitrarily selected from the preset antenna weight set; executing an antenna weight updating process to distribute the antenna weight to each group of communication signals to be sent respectively; executing a cell parameter updating process to compare the signal index with the antenna weight index, setting a check identifier of a communication signal to be sent according to a comparison result, and configuring an antenna weight for the communication signal to be sent according to different check identifiers in different modes; and sending the communication signal to be sent according to the configured antenna weight. The problem that flexible configuration cannot be performed for different practical environments due to the fact that a sending mode of a fixed weight is single is solved, the sequence of cell parameter updating and antenna weight updating is adjusted to adapt to an antenna weight configuration process under different environments, the antenna weight can be guaranteed to be flexibly distributed, and system performance and the frequency spectrum utilization rate are improved.
Secondly, when the antenna weight index is determined not to be the subset of the signal index, the antenna weight distribution process can still be executed at the moment so as to ensure the normal sending of the communication signal; when the antenna weight index is determined to be the subset of the signal index, the effect of executing the antenna weight distribution process is optimal, and the performance of the communication system and the frequency spectrum utilization rate of the base station can be further improved.
