Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When the network capacity or coverage needs to be enlarged, expanding the number of RRUs in the network is a low-cost solution. However, the number of RRUs is limited by the processing capability of the BBU and the transmission capability of the optical fiber between the BBU and the RRUs. Accordingly, an embodiment of the present invention provides a data uplink transmission method. Fig. 1 is a schematic flow diagram of a data uplink transmission method according to an embodiment of the present invention, and as shown in fig. 1, an execution main body of the method is a data uplink transmission device, and the data uplink transmission device may be disposed between a BBU and an RRU or disposed on the BBU. The method comprises the following steps:
Specifically, the uplink data sent by any RRU is the data that the RRU needs to send to the BBU. In the embodiment of the invention, the data uplink transmission device is connected with each RRU in the network and receives uplink data sent by each RRU. It should be noted that the number of RRUs in the network is not limited by the processing capability of the BBU and the transmission capability of the optical fiber between the BBU and the RRU, and the embodiment of the present invention does not specifically limit the number of RRUs in the network.
And step 120, combining the uplink data sent by each RRU based on a preset combination relationship to obtain combined data.
Specifically, the preset combination relationship is a preset relationship between each RRU and the combined data, and the preset combination relationship is used to indicate how to combine the uplink data sent by each RRU, so as to obtain one or more combined data. The preset combination relationship may be determined by the data uplink transmission apparatus, or may be sent to the data uplink transmission apparatus by the BBU or the RRU, which is not specifically limited in this embodiment of the present invention. The preset combination relationship may be determined according to the uplink capacity of each RRU in the network, or may be determined according to a cell corresponding to each RRU in the network, which is not specifically limited in this embodiment of the present invention.
It should be noted that the number of the combined data obtained after the combination is less than or equal to the number of the RRUs in the network, and the number of the combined data obtained after the combination can adapt to the processing capability of the BBU and the transmission capability of the optical fiber between the BBU and the RRUs. For example, the network includes 5 RRUs, i.e., RRU1 through RRU5, the preset combination relationship is that RRU1, RRU2 and RRU3 are a group, and RRU4 and RRU5 are a group. After the uplink data sent by each RRU is obtained, based on a preset combination relationship, the uplink data sent by the RRU1, the RRU2, and the RRU3 are combined into combined data a, and the uplink data sent by the RRU4 and the RRU5 are combined into combined data B.
Specifically, the data uplink transmission device is connected to the BBU in the network, and after the uplink data sent by each RRU are merged, the combined data obtained by merging are sent to the BBU.
The method provided by the embodiment of the invention combines the uplink data sent by each RRU based on the preset combination relationship and then sends the combined uplink data to the BBU, so that the expansion of the number of the RRUs in the network is not limited by the processing capacity of the BBU and the transmission capacity of the optical fiber between the BBU and the RRU, and a simple, feasible and low-cost solution is provided for realizing the expansion of the network capacity or the coverage area.
Based on the above embodiment, in the method, the preset combination relationship is obtained based on the cell establishment information.
Specifically, the cell establishment information includes a cell corresponding to each RRU in the network, and usually, a plurality of RRUs may form one cell or a plurality of cells. Based on the cell establishment information, each RRU constituting one cell can be regarded as a group, and a preset combination relationship is established therefrom, and the preset combination relationship can be flexibly changed according to adjustment of the cell establishment information. For example, the network includes 7 RRUs, that is, RRU1 to RRU7, where RRU1, RRU4, RRU6, and RRU7 correspond to cell a, RRU2 corresponds to cell B, and RRU3 and RRU5 correspond to cell C, then in the predetermined combination relationship, RRU1, RRU4, RRU6, and RRU7 are in a group, RRU2 is in a group, and RRU3 and RRU5 are in a group.
According to the method provided by the embodiment of the invention, the preset combination relationship is acquired through the cell establishment information, so that the uplink data sent by the RRUs in the same cell are merged and then sent to the BBU, and the problems of data disturbance and poor service experience caused by blindly merging the uplink data sent by the RRUs in different cells are avoided.
Based on any of the above embodiments, step 120 further includes: and receiving a preset combination relation sent by the BBU.
Specifically, before the data uplink transmission device merges the received uplink data sent by each RRU, a preset combination relationship sent by the BBU needs to be received as a merging basis for the uplink data sent by each RRU. That is to say, the preset combination relationship in the embodiment of the present invention is generated by the BBU and sent to the data uplink transmission apparatus, and the data uplink transmission apparatus does not need to acquire the cell establishment information before executing the data transmission method, or does not need to establish the preset combination relationship according to the cell establishment information or other information, thereby reducing the requirement on the processing capability of the data uplink transmission apparatus.
Based on any of the above embodiments, step 120 specifically includes: acquiring the number of each member in any combination based on a preset combination relation; and selecting radio frequency channel data corresponding to each member number from the uplink data sent by each RRU, and combining the radio frequency channel data to obtain combined data corresponding to the combination.
Specifically, the preset combination relationship defines a relationship between each RRU and a plurality of combinations, where each combination includes a plurality of member numbers, and the member number is used to indicate the number of the RRU included in the combination. For any combination in the preset combination relationship, each member number contained in the combination is firstly acquired. And then, aiming at each obtained member number, determining the RRU corresponding to each member number, selecting the uplink data sent by the RRU corresponding to each member number from the uplink data sent by each RRU, combining the selected uplink data, and taking the combined data as the combined data corresponding to the combination.
Based on any of the above embodiments, step 130 specifically includes: and sending the combined data corresponding to any combination to the BBU through the logic channel corresponding to the combination.
Specifically, the preset combination relationship includes not only a relationship between each RRU and a plurality of combinations, but also a logical channel corresponding to each combination. Here, the number of logical channels is equal to or less than the maximum number of channels that the BBUs are allowed to access simultaneously. After the combination of the uplink data sent by each RRU is completed based on the preset combination relationship to obtain a plurality of combined data, a logic channel corresponding to any combined data is obtained, and the combined data is sent to the BBU through the corresponding logic channel.
The BBU in the network has the processing capacity of 16 antennas, and the optical fiber can only transmit the data capacity of 16 antennas, and each access of one RRU occupies the data capacity of 4 antennas, that is, the BBU can access 4 RRUs at most. In this state, the number of RRUs in the network needs to be expanded to 8 to obtain larger communication capacity and coverage. To this end, based on any of the above embodiments, the data uplink transmission capable of adapting to the BBU processing capability and the optical fiber transmission capability is implemented by the following method, and fig. 2 is a schematic flow chart of a data uplink transmission method according to another embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
and step 210, the BBU acquires a preset combination relationship according to the cell establishment information corresponding to the 8 RRUs, and sends the preset combination relationship to the data uplink transmission device. Here, 8 RRUs are respectively RRU1 to RRU8, and the BBU determines that RRU1 and RRU5, RRU2 and RRU6, RRU3 and RRU7, and RRU4 and RRU8 have the same logical channel configuration according to the cell establishment information, that is, RRU1 and RRU5, RRU2 and RRU6, RRU3 and RRU7, and RRU4 and RRU8 are respectively grouped, and thus the following preset combination relationship is obtained:
wherein, any row represents a logic channel corresponding to the combined data after performing uplink data combination, and each logic channel corresponds to the data capacity of 4 antennas. Any column indicates whether one RRU participates in uplink data combining in different combinations, that is, when corresponding to different logical channels, "Y" indicates participation in combining, and "N" indicates non-participation in combining.
And step 220, the data uplink transmission device receives and stores the preset combination relationship sent by the BBU.
In step 230, 8 RRUs in the network respectively send uplink data to the data uplink transmission device through the ethernet, and the data uplink transmission device receives the uplink data sent by each RRU.
And step 250, transmitting the combined data to the BBU through the optical fiber connected between the data uplink transmission device and the BBU based on the logic channel corresponding to each combined data in the preset combination relation.
It should be noted that, in the embodiment of the present invention, the merged uplink data is time domain data, and may also be frequency domain data after time-frequency transformation, which is not specifically limited in this embodiment of the present invention.
The method provided by the embodiment of the invention combines the uplink data sent by each RRU based on the preset combination relationship and then sends the combined uplink data to the BBU, so that the expansion of the number of the RRUs in the network is not limited by the processing capacity of the BBU and the transmission capacity of the optical fiber between the BBU and the RRU, and a simple, feasible and low-cost solution is provided for realizing the expansion of the network capacity or the coverage area. In addition, the preset combination relationship is acquired through the cell establishment information, so that the uplink data sent by the RRUs in the same cell are merged and then sent to the BBU, and the problems of data disturbance and poor service experience caused by blind merging of the uplink data sent by the RRUs in different cells are solved.
Based on any of the above embodiments, fig. 3 is a schematic flow diagram of a data downlink transmission method provided in the embodiment of the present invention, and as shown in fig. 3, an execution main body of the method is a data downlink transmission device, and the data downlink transmission device may be disposed between the BBU and the RRU, or may be disposed on the BBU. The method comprises the following steps:
and step 310, receiving the combined data sent by the BBU.
Specifically, the combined data is obtained by combining downlink data to be sent to the plurality of RRUs by the BBU, and the single combined data corresponds to one logical channel of the BBU and only occupies the processing capability and the optical fiber transmission capability of the BBU corresponding to the one logical channel. In the embodiment of the invention, the BBU corresponds to the data downlink transmission device, and the BBU sends the combined data to the data downlink transmission device, which is equivalent to sending the downlink data which needs to be sent to a plurality of RRUs to the data downlink transmission device.
And 320, acquiring the member RRU corresponding to the combined data based on the preset combination relation.
Specifically, the preset combination relationship is a preset relationship between each RRU and the combination data, where the preset combination relationship is used to indicate how to distribute the combination data to the corresponding member RRUs, and the preset combination relationship may include one or more combination data, and each combination data may correspond to one or more member RRUs. Here, the member RRU refers to an RRU included in a combination corresponding to the combined data. The preset combination relationship may be determined by the data downlink transmission apparatus, or may be sent to the data downlink transmission apparatus by the BBU or the RRU, which is not specifically limited in this embodiment of the present invention. The preset combination relationship may be determined according to downlink capacities of the RRUs in the network, or may be determined according to cells corresponding to the RRUs in the network, which is not specifically limited in this embodiment of the present invention.
It should be noted that the number of the combined data included in the preset combination relationship is less than or equal to the number of the RRUs in the network, and the number of the combined data can be adapted to the BBU processing capability and the optical fiber transmission capability between the BBU and the RRUs. The number of the member RRUs corresponding to any combination data in the preset combination relation is less than or equal to the number of the RRUs in the network. For example, the network includes 5 RRUs, i.e., RRU1 through RRU5, where RRU1, RRU2, and RRU3 in the preset combination relationship are a group, and RRU4 and RRU5 are B group. After the combined data a and the combined data B are obtained, based on a preset combination relationship, it is determined that the member RRUs corresponding to the combined data a include RRU1, RRU2 and RRU3, and the member RRUs corresponding to the combined data B include RRU4 and RRU 5.
Specifically, the data downlink transmission apparatus is connected to each RRU in the network. And after determining the member RRUs corresponding to the combined data, sending the combined data to each member RRU as downlink data of each member RRU. Here, downlink data corresponding to any RRU, that is, data that a BBU needs to be sent to the RRU.
The method provided by the embodiment of the invention distributes the combined data sent by the BBU as the downlink data to the corresponding member RRU based on the preset combination relation, so that the expansion of the number of RRUs in the network is not limited by the processing capacity of the BBU and the transmission capacity of the optical fiber between the BBU and the RRU, and a simple, feasible and low-cost solution is provided for realizing the expansion of the network capacity or the coverage area.
Based on any of the above embodiments, in the method, the preset combination relationship is obtained based on the cell establishment information.
Specifically, the cell establishment information includes a cell corresponding to each RRU in the network, and usually, a plurality of RRUs may form one cell or a plurality of cells. Based on the cell establishment information, each RRU constituting one cell can be regarded as a group, and a preset combination relationship is established therefrom, and the preset combination relationship can be flexibly changed according to adjustment of the cell establishment information. For example, the network includes 7 RRUs, that is, RRU1 to RRU7, where RRU1, RRU4, RRU6, and RRU7 correspond to cell a, RRU2 corresponds to cell B, and RRU3 and RRU5 correspond to cell C, then in the predetermined combination relationship, RRU1, RRU4, RRU6, and RRU7 are in a group, RRU2 is in a group, and RRU3 and RRU5 are in a group.
According to the method provided by the embodiment of the invention, the preset combination relationship is acquired through the cell establishment information, so that the combined data is distributed to the RRUs in the same cell as the downlink data, and the problems of data disturbance and poor service experience caused by blindly distributing the combined data to the RRUs in different cells are avoided.
Based on any of the above embodiments, step 320 further includes: and receiving a preset combination relation sent by the BBU.
Specifically, before the data downlink transmission apparatus determines, for the received combined data, that the corresponding member RRU distributes the downlink data, a preset combination relationship sent by the BBU needs to be received as a basis for distributing the downlink data. That is to say, the preset combination relationship in the embodiment of the present invention is generated by the BBU and sent to the data downlink transmission apparatus, and the data downlink transmission apparatus does not need to acquire the cell establishment information before executing the data transmission method, or does not need to establish the preset combination relationship according to the cell establishment information or other information, thereby reducing the requirement on the processing capability of the data downlink transmission apparatus.
Based on any of the above embodiments, step 320 specifically includes: acquiring each member number in a combination corresponding to any combination data based on a preset combination relation; and taking the RRU corresponding to any member number as the member RRU of the combined data.
Specifically, the preset combination relationship defines a relationship between each RRU and a plurality of combinations, where each combination includes a plurality of member numbers, and the member number is used to indicate the number of the RRU included in the combination. For any combination data sent by the BBU, each member number contained in the combination corresponding to the combination data is determined based on a preset combination relation. Then, aiming at each obtained member number, determining the RRU corresponding to each member number, and taking the RRU corresponding to each member number as the member RRU corresponding to the combined data,
Based on any of the above embodiments, step 310 specifically includes: and receiving the combined data sent by the BBU based on any logic channel.
Specifically, the preset combination relationship includes not only a relationship between each RRU and a plurality of combinations, but also a logical channel corresponding to each combination. Here, the number of logical channels is equal to or less than the maximum number of channels that the BBUs are allowed to access simultaneously. When the BBU sends the combined data, the BBU sends the combined data based on the logic channel corresponding to the combined data. Therefore, when the data downlink transmission apparatus receives any combined data, the combination corresponding to the combined data can be determined through the logical channel for transmitting the combined data, so as to determine the member RRUs corresponding to the combined data, and the combined data is distributed to each member RRU as downlink data.
The BBU in the network has the processing capacity of 16 antennas, and the optical fiber can only transmit the data capacity of 16 antennas, and each access of one RRU occupies the data capacity of 4 antennas, that is, the BBU can access 4 RRUs at most. In this state, the number of RRUs in the network needs to be expanded to 8 to obtain larger communication capacity and coverage. To this end, based on any of the above embodiments, the data downlink transmission capable of adapting to the BBU processing capability and the optical fiber transmission capability is implemented by the following method, and fig. 4 is a schematic flow chart of a data downlink transmission method according to another embodiment of the present invention, as shown in fig. 4, the method includes the following steps:
and step 410, the BBU acquires a preset combination relationship according to the cell establishment information corresponding to the 8 RRUs, and sends the preset combination relationship to the data downlink transmission device. Here, 8 RRUs are respectively RRU1 to RRU8, and the BBU determines that RRU1 and RRU5, RRU2 and RRU6, RRU3 and RRU7, and RRU4 and RRU8 have the same logical channel configuration according to the cell establishment information, that is, RRU1 and RRU5, RRU2 and RRU6, RRU3 and RRU7, and RRU4 and RRU8 are respectively grouped, and thus the following preset combination relationship is obtained:
wherein, any row represents a logic channel corresponding to the combined data after performing uplink data combination, and each logic channel corresponds to the data capacity of 4 antennas. Any column indicates whether one RRU participates in uplink data combining in different combinations, that is, when corresponding to different logical channels, "Y" indicates participation in combining, and "N" indicates non-participation in combining.
And step 430, the BBU sends the combined data to the data downlink transmission device through the optical fiber. And the data downlink transmission device receives the combined data sent by the BBU.
It should be noted that the downlink data distributed in the embodiment of the present invention may be time domain data or frequency domain data after time-frequency transformation, and this is not specifically limited in the embodiment of the present invention.
