Description

Method and device for adjusting uplink networking of digital indoor division cells

Technical Field

The invention relates to the technical field of communication, in particular to a method and a device for adjusting uplink networking of a digital room partition cell.

Background

With the rapid development of cellular network communication technology, many indoor application scenarios are generated. In order to realize network deployment in indoor application scenes, a digital indoor subsystem is applied in a large quantity. The indoor subsystem is called an indoor signal distribution system, and a cell covered by the indoor subsystem is called an indoor cell. The digital room subsystem is a three-level architecture, and is respectively a baseband processing Unit (English: base Band Unit, abbreviated as BBU), a miniature remote radio Unit hub (English: pico Remote Radio Unit Hub, abbreviated as pHUB) and a miniature remote radio Unit (English: pico Remote Radio Unit, abbreviated as pRRU). The BBU is generally used for completing baseband part signal processing, uplink and downlink signaling interaction and service processing; pHUB is generally used for completing the aggregation and distribution of uplink and downlink signals and data in an radio frequency domain, and simultaneously provides remote power supply for pRRU; pRRU is commonly used for micropower radio frequency transceiving to achieve distributed coverage of indoor signals. One BBU may be linked to one or more phebs, one pheb may be linked to a plurality of prrus, each covering a region. The working principle of the digital room subsystem is as follows: in the downlink process, the BBU sends signals to the pHUB, the pHUB and the pRRUs are connected through a network cable, the pHUB distributes the signals to the pRRUs, and after the pRUs process the signals into radio frequency signals, the radio frequency signals are accessed to the indoor terminals through transmission equipment such as radio frequency feeders, antennas and the like. In the uplink process, the indoor terminal sends feedback signals to the pRRUs, each pRRU sends the feedback signals to the pHUB, and the pHUB converges the feedback signals and then transmits the feedback signals to the BBU.

In the process of carrying out service transmission between the digital indoor subsystem and the user terminal, the digital indoor subsystem can respectively send downlink signals to the user terminal under the coverage area of each pRRU in the indoor subsystem. Accordingly, the user terminal may transmit an uplink signal to the indoor subsystem through the pRRU covering the current range.

The capacity of the cellular network is mainly obtained by multiplexing time-frequency resources, that is, transmitting multi-stream data on the same Resource Block (RB), the number of streams of data that can be transmitted is determined by the number of antennas of the base station and the terminal, and the more the number of antennas, the more the number of streams of data that can be transmitted on the same time-frequency resources.

The receiving and transmitting channel of the digital room subsystem is usually 2T2R (English: two transmit two receive, wherein T represents transmit, R represents receive) or 4T4R, wherein 2T2R represents that 2 channels are used for downlink signal transmission, 2 channels are used for uplink signal receiving, a cell of 2T2R is configured, theoretically, the maximum uplink flow numbers are respectively 2 flows (two flows), and the maximum downlink flow numbers are 2 flows; 4T4R means that 4 channels are used for downlink signal transmission, 4 channels are used for uplink signal reception, and a cell of 4T4R is configured, and theoretically, the maximum uplink flow number is 4 flows, and the maximum downlink flow number is 4 flows. In order to expand the capacity of a cell, a virtual multi-antenna technology may be adopted, that is, a plurality of physical channels are combined into a logical cell with more antennas, for example, a cell with a virtual 16T16R, and the maximum uplink and downlink stream numbers that the cell can theoretically support are 16 streams respectively.

When the digital indoor division cells adopting the virtual multi-antenna technology are used for networking, the uplink networking configuration and the downlink networking configuration are both the same configuration, and the uplink networking configuration and the downlink networking configuration are not adjusted after the configuration is completed normally, so that the uplink networking configuration and the downlink networking configuration cannot be dynamically adjusted according to the change of the number of access users, and the resource waste is caused.

Detailed Description

The implementation principle, the specific embodiments and the corresponding beneficial effects of the technical solution of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic diagram of a digital cell division networking. The digital room is divided into three-level architecture, which is respectively a baseband processing unit BBU, a miniature remote radio unit hub pHUB and a miniature remote radio unit pRRU. In fig. 1, only the mini-remote pRRU is shown, each small block in the figure represents one pRRU, the digitizing room cell includes 16 prrus, and the 16 prrus are allocated to 4 radio combining groups. The positional relationship of pRRU in fig. 1 indicates its actual spatial relationship, and the closer the two pRRU are in fig. 1, the closer the two pRRU are in actual spatial relationship. In general, after a digitizing cell is determined, the number of prrus and the number of radio frequency combining groups included in the digitizing cell are fixed. In the following description, pRRU is 4T4R, i.e., one pRRU has 4 maximum upstream streams and 4 maximum downstream streams. For pRRUs in the same radio frequency combining group, in the downlink direction, the BBU sends initial downlink data to the pHUB, the pHUB copies the initial downlink data into a plurality of parts and distributes the parts to each pRRU, wherein the content of the downlink data received by each pRRU is the same; in the uplink direction, each pRRU receives uplink data sent by the terminal, and sends the uplink data to the pHUB, the pHUB performs radio frequency combination on the uplink data of each pRRU in the radio frequency combination set, and the uplink data on each pRRU is sent to the BBU for demodulation. One radio frequency combining group may include one pRRU or a plurality of prrus, where the radio frequency combining group configured by the prrus is also called a radio frequency combining cell. The plurality of radio frequency combining cells form a digital room dividing cell.

Common networking modes of pRRU in a digitalized indoor cell are shown in fig. 1, and include spatial isolation networking and multi-antenna flower arrangement networking. The space isolation group list shows that pRRU in the same radio frequency combining cell in the digital room dividing cell is positioned in adjacent areas on the layout of physical space, except the junction of the radio frequency combining cells, the areas covered by each radio frequency combining cell are not overlapped; the multi-antenna flower arrangement group list shows that pRRU in the same radio frequency combining cell in the digital room dividing cell is located in a non-adjacent area on the layout of physical space, and the coverage areas of each radio frequency combining cell are overlapped. The space isolation networking and the multi-antenna flower arrangement networking have advantages and disadvantages in practical application.

In the space isolation networking, because the pRRUs in the radio frequency combined cells are located in adjacent areas on the layout of the physical space, the areas covered by each radio frequency combined cell are rarely overlapped, so that except for the junction of the radio frequency combined cells, users at other positions can only receive and transmit signals through the pRRUs in one radio frequency combined cell corresponding to the position, therefore, the pRRUs are equivalent to most of the positions of the digital room sub-cells, still 4T4R, and 16T16R is achieved by processing user equipment at different positions at the same time. In the downlink signal transmission process, because the terminal equipment is generally 2T4R, the terminal equipment can only receive 4 pieces of stream data at most in one position, and therefore, the same terminal equipment can realize the transmission of the downlink signal through the radio frequency combining cell corresponding to the position of the terminal equipment. The digital room with the isolation networking is divided into cells, different radio frequency combining cells can adopt the same frequency through reasonable arrangement, frequency multiplexing is realized, and the utilization rate of resources is improved. When transmitting uplink signals, the pHUB performs radio frequency combination processing on the uplink signals on each pRRU when performing radio frequency combination on the uplink signals in the same radio frequency combination cell, and the same radio frequency combination cell is still equivalent to a 4T4R cell. Therefore, in uplink signal transmission, if space isolation networking is adopted, only 4 stream data transmission can be realized at other positions except at the junction of different radio frequency combining cells. When the user equipment is only concentrated at a certain position, the uplink transmission capacity of the digital room subarea is greatly reduced because only 4 data transmission streams can be simultaneously carried out.

In the multi-antenna flower arrangement networking, pRRU in the same radio frequency combined cell is located in a non-adjacent area on the layout of physical space, and the coverage area of each radio frequency combined cell is overlapped, which is equivalent to constructing a digital indoor division cell with each position reaching 16T 16R. However, in the multi-antenna flower arrangement networking, different radio frequency combined cells cannot perform frequency multiplexing, so that when downlink signals are transmitted, the user equipment is generally 2T4R, that is, only 4 streams can be simultaneously transmitted at one position, and the transmission requirement can be met. In actual use, the downlink networking generally adopts space isolation networking, and the resource utilization rate is improved through frequency multiplexing. And in the uplink signal transmission, most areas of the multi-antenna flower arrangement networking are 16R receiving, and each position of the uplink can realize 16 stream data transmission. Therefore, when the digital room is divided into cells and uplink networking is set, the multi-antenna flower arrangement networking is preferably selected.

The digital room division cells of the virtual multi-antenna technology shown in fig. 1 include 4 radio frequency combined cells and 16 pRRU, and in the practical application process, the number of radio frequency combined cells and the number of pRRU in the digital room division cells are set according to the practical layout situation, which is not limited in the present application. In fig. 1, the number of prrus in each radio frequency combined cell is the same, which is just an example case, and in the actual application process, the number of prrus in each radio frequency combined cell may be the same or different, and may be set according to specific situations.

In the existing digital indoor partition using the virtual multi-antenna technology, the space isolation networking is generally used for uplink and downlink at the same time, and according to the analysis, if the terminal user concentrates at a certain position during uplink signal transmission, the digital indoor partition can only transmit 4 streams of data, so that the capacity of each position of the uplink is limited, and the uplink transmission capacity of the virtual multi-antenna networking system is reduced.

Therefore, there is a need to design a method for adjusting uplink networking of a digital cell using a virtual multi-antenna technology, which can maximally optimize uplink transmission capability of the digital cell using the virtual multi-antenna technology.

In an embodiment of the present application, the terminal device is a device having a wireless transceiving function. The terminal device may be a mobile phone, a tablet computer, a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an enhanced display (Augmented Reality, AR) terminal device, a wireless device in industrial control, a vehicle-mounted terminal device, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a wearable terminal device, or the like. The embodiments of the present application are not limited to application scenarios. The terminal device may also be a terminal, a User Equipment (UE), an access terminal device, a vehicle-mounted device, an industrial control terminal, a UE unit, a UE station, a mobile station, a remote terminal device, a mobile device, a UE apparatus, or the like. The terminal device may also be fixed or mobile, and in this embodiment, only the terminal device is used as the UE for exemplary illustration.

Referring to fig. 2, fig. 2 is a flowchart of a method for adjusting uplink networking of a digital indoor partition according to the present invention. The cell uplink networking adjustment method is used for dividing a digital room into cells by using a virtual multi-antenna technology, and the digital room dividing cells comprise N radio frequency combined cells when uplink signals are transmitted, wherein N is more than or equal to 2; the digitizing cell also includes M pRRUs, where M is greater than or equal to N. The N radio frequency combining cells include a first radio frequency combining cell, and the first radio frequency combining cell may be any one of the N radio frequency combining cells.

The method for adjusting the uplink networking of the digital cell division by using the virtual multi-antenna technology comprises the following steps of S1: and determining whether the first radio frequency combined cell meets the uplink member adjustment condition, and executing S2 if the first radio frequency combined cell meets the uplink member adjustment condition. When the first radio frequency combined cell meets the uplink member adjustment condition, the uplink member composition in the first radio frequency combined cell is indicated to not meet the uplink transmission condition.

The uplink member adjustment condition may be that the uplink utilization rate of a physical resource block (english: physical Resource Block, abbreviated as PRB) in the first radio frequency combined cell reaches a first threshold, and when the uplink utilization rate of the physical resource block in the first radio frequency combined cell reaches the first threshold, it indicates that the load in the first radio frequency combined cell is higher, and the uplink pRRU member in the first radio frequency combined cell may be adjusted. Specifically, the number of uplink pRRU members in the first radio frequency combined cell may be reduced; or, the uplink pRRU member in the first radio frequency combined cell may be exchanged with the uplink pRRU member part in the second radio frequency combined cell with the lowest PRB uplink utilization rate in the N radio frequency combined cells. For example, part of uplink pRRU members in the first radio frequency combining cell are distributed to other radio frequency combining cells, so that users connected with the part of uplink pRRU members are divided into other radio frequency combining cells, the load of the first radio frequency combining cell is reduced, and the uplink transmission capacity of the digital room dividing cell is improved. For example, an uplink member pRRU1 in a first radio frequency combined cell is allocated to a second radio frequency combined cell, so that a user to which the pRRU1 is connected is divided into the second radio frequency combined cell. For another example, the uplink member pRRU1 of the first radio frequency combining cell is allocated to the second radio frequency combining cell, and the uplink member pRRU2 of the first radio frequency combining cell is allocated to the third radio frequency combining cell. Or exchanging the uplink pRRU member in the first radio frequency combined cell with the uplink pRRU member part in the second radio frequency combined cell with the lowest PRB uplink utilization rate in the N radio frequency combined cells. For example, pRRU1 in the first radio frequency combined cell is allocated to the second radio frequency combined cell, and pRRU3 in the second radio frequency combined cell is allocated to the first radio frequency combined cell. The first threshold may be a specifically determined value, such as any one of 60% -90%; the first threshold value can be dynamically adjusted according to actual application conditions, the PRB utilization rate of the digitalized indoor partition cell is monitored in real time, and a certain value is floated according to the PRB utilization rate, namely 20% is floated as the first threshold value. The specific setting method and specific numerical values of the first threshold value are not limited in the present invention.

When determining whether the PRB uplink utilization rate in the first radio frequency combined cell reaches a first threshold value, measuring the PRB uplink utilization rate in the first radio frequency combined cell. In performing the PRB uplink utilization measurements, the measurements may be performed by the BBU, or an operation and maintenance center (English: operation and Maintenance Center, abbreviated OMC) may be performed based on information provided by the BBU. Taking the measurement of the uplink utilization rate of the PRB by using OMC as an example, the specific method comprises the following steps: in the evaluation period, the BBU counts the number of uplink PRBs used and the number of available uplink PRBs in the first radio frequency combining cell in unit time, wherein the unit time can be in millisecond level, such as 1ms,2ms and the like, and the unit time can be adjusted according to different precision requirements, such as 10ms and the like. Reporting the statistical result in unit time to OMC, and averaging the measurement results in each unit time in the evaluation period by OMC, wherein the uplink PRB utilization rate is obtained by comparing the number average value of uplink PRB use with the available number of uplink PRB. The evaluation period is generally selected to be a fixed period, and the evaluation period is generally much longer than a unit time, such as the evaluation period takes 15 minutes, 30 minutes, 60 minutes, 24 hours, and the like.

The uplink member adjustment condition may also be that the number of the user equipments connected in the first radio frequency combining cell reaches a second threshold, and when the number of the user equipments in the first radio frequency combining cell reaches the second threshold, it indicates that the number of the user equipments connected in the first radio frequency combining cell is more, so that uplink pRRU members in the first radio frequency combining cell may be adjusted, and the adjustment method is similar to that when the PRB uplink utilization of the first radio frequency combining cell reaches the first threshold, so that the number of uplink pRRU members in the first radio frequency combining cell may be reduced; or, the uplink pRRU member in the first radio frequency combined cell may be exchanged with the uplink pRRU member part in the second radio frequency combined cell with the lowest PRB uplink utilization rate in the N radio frequency combined cells. And will not be described in detail herein. The second threshold may be a specifically determined value, such as any one of 50-100; the second threshold may also be dynamically adjusted according to the actual application, for example, an average value of the ue connected to the radio frequency combining cell in the digitizing cell in the previous period is calculated, and a certain value is floated up to 20 according to the average value, as the second threshold. The specific setting method and specific numerical values of the second threshold value are not limited in the present invention.

When determining whether the number of the connected user equipment in the first radio frequency combined cell reaches the second threshold, firstly measuring the number of the connected user equipment in the first radio frequency combined cell. When measurement is performed, each ue starts channel sounding reference signal (in english: sounding Reference Signal, abbreviated SRS) poll measurement, and taking a first ue as an example, the first ue transmits an uplink subframe, where the last symbol user in the uplink subframe transmits the SRS. In specific implementation, the BBU may control the first ue to perform uplink transmission on the SRS symbol by only one pRRU, that is, on the SRS symbol, turn off the other RRUs and turn on only one pRRU, so as to measure, on the pRRU, the uplink reference signal received power (english: reference Signal Receiving Power, abbreviated: RSRP) of the SRS sent by the first ue through the pRRU. For example, in the uplink subframe 1, only the first pRRU is turned on, so as to obtain the uplink RSRP of the first user equipment corresponding to the first pRRU; and so on, measuring the uplink RSRP of the first user equipment corresponding to each pRRU in the digital room partition cell. And when judging, if the uplink RSRP is larger than a third threshold, the first user equipment is considered to be the pRRU connected user equipment, and if the uplink RSRP is not larger than the third threshold, the first user equipment is considered to be not the pRRU connected user equipment. And counting the number of the user equipment connected under all the uplink pRRUs in the first radio frequency combined cell, and removing redundant user equipment in the counting process, namely counting only once if the first user equipment belongs to the user equipment connected with a plurality of uplink pRRUs at the same time.

Of course, it can be understood that the uplink member adjustment condition may also be a combination of the PRB uplink utilization in the first radio frequency combining cell and the number of connected user equipments in the first radio frequency combining cell, for example, the PRB uplink utilization in the first radio frequency combining cell reaches the third threshold and the number of connected user equipments in the first radio frequency combining cell reaches the fourth threshold. Wherein the third threshold may be the same as or different from the first threshold and the fourth threshold may be the same as or different from the second threshold. Of course, the uplink member adjustment condition may also include other uplink pRRU members, for example, the number of uplink pRRU members included in the radio frequency combined cell, and when the number of uplink pRRU members in the radio frequency combined cell is greater than the fifth threshold, the uplink pRRU members in the radio frequency combined cell are adjusted. Or when the difference between the number of the uplink pRRU members in the radio frequency combined cell and the number of the uplink pRRU members in the radio frequency combined cell is larger than a sixth threshold, adjusting the uplink pRRU members in the radio frequency combined cell.

S2: and adjusting the uplink pRRU members of the N radio frequency combined cells, wherein the PRB uplink utilization rate of the first radio frequency combined cell after adjustment is smaller than a first set threshold value.

When adjusting uplink pRRU members of N radio frequency combined cells in the digital room sub-cells, adjusting part of the radio frequency combined cells in the N radio frequency combined cells, for example, only adjusting a first radio frequency combined cell and a second radio frequency combined cell, wherein the uplink pRRU members in the rest radio frequency combined cells are not adjusted; when the adjustment is performed, all radio frequency combining cells in the N radio frequency combining cells can be adjusted. When uplink pRRU members of each radio frequency combining cell in the digitizing room dividing cell are adjusted, adjacent pRRUs in space positions are distributed to different radio frequency combining cells as much as possible, for example, adjacent pRRUs in M pRRUs are distributed to different radio frequency combining cells, and of course, each group of adjacent pRRUs can be redistributed, or more important adjacent pRRU groups can be distributed, for example, adjacent pRRU groups where uplink pRRU members in the first radio frequency combining cell before adjustment are located are distributed preferentially. After adjustment, the uplink PRB utilization rate of the first radio frequency combining cell is smaller than a first set threshold value. The first set threshold may be the same as the first threshold or lower than the first threshold, which is not limited in this application. The first set threshold corresponds to a first radio frequency combining cell, the set threshold in each radio frequency combining cell may be the same as the first set threshold, or each radio frequency combining cell may correspond to one set threshold, for example, the second radio frequency combining cell sets a second set threshold, which may be the same as or different from the first set threshold, and the application is not limited.

After adjustment, pRRU in the same radio frequency combined cell is not adjacent in spatial position as much as possible. pRRU in the same radio frequency combined cell is not adjacent in space position, the coverage of the radio frequency combined cell can be enlarged, so that the same position can be covered by a plurality of radio frequency combined cells, when the user equipment is concentrated in a certain position, the plurality of radio frequency combined cells can simultaneously carry out uplink data transmission on the user equipment in the position, and the uplink transmission capacity is improved. In an ideal case, the uplink pRRU networking in the adjusted digital indoor division cell is adjusted to be a multi-antenna flower arrangement networking, namely, the pRRUs in the same radio frequency combining cell are not adjacent in space.

We describe the above digital cell uplink networking adjustment method in one embodiment. The digital room sub-district comprises N radio frequency combined sub-districts, wherein N is more than or equal to 2, and the N radio frequency combined sub-districts comprise a first radio frequency combined sub-district and a second radio frequency combined sub-district. And the digitizing cell comprises M pRRUs, wherein M.gtoreq.N, the M pRRUs comprising a first pRRU and a second pRRU. When the first radio frequency combining cell reaches an uplink member adjusting condition, uplink pRRU members of all radio frequency combining cells in the digital room dividing cell are adjusted, wherein pRRUs adjacent to each other are distributed to different radio frequency combining cells. And if the first pRRU and the second pRRU are adjacent pRRUs, the first pRRU is allocated to the second radio frequency combining cell, and the second pRRU is allocated to other radio frequency combining cells except the second radio frequency combining cell. If the adjusted first radio frequency combining cell includes the first pRRU and the second pRRU, the first pRRU and the second pRRU are not adjacent in location. The digitalized room division cell includes 2 radio frequency combined cells, which are denoted as a first radio frequency combined cell and a second radio frequency combined cell, and 6 prrus are exemplified, wherein the 6 prrus are denoted as P1, P2, P3, P4, P5 and P6, respectively, and the pRRU pairs having a position adjacent relationship can be determined to be P1 and P2, P1 and P3, P2 and P4, P3 and P5, and P2 and P6. And sequentially distributing the pRRU pairs adjacent to the positions to the first radio frequency combining cell and the second radio frequency combining cell respectively as shown in table 1.

Radio frequency combining cell	First radio frequency combining cell	Second radio frequency combined cell
			Uplink pRRU member	P1，P4，P5，P6	P2，P3

TABLE 1

When the allocation is performed, P1 and P2 are allocated to the first radio frequency combining cell and the second radio frequency combining cell respectively, and when the P3 allocation is performed, since P3 is adjacent to P1 and P1 is already allocated to the first radio frequency combining cell, P3 is allocated to the second radio frequency combining cell. Similarly, in P4 allocation, P4 is allocated to the first radio frequency combining cell because P4 and P2 are adjacent and P2 has already been allocated to the second radio frequency combining cell. According to the same rule, P5 and P6 are both allocated to the first radio frequency combined cell.

As can be seen from the above allocation process, when uplink pRRU allocation is performed, if no adjacent pRRU is allocated to the corresponding radio frequency combining cell, the adjacent pRRU is allocated to different radio frequency combining groups in any order, for example, when P1 and P2 are allocated, P1 may be allocated to the first radio frequency combining cell, P2 may be allocated to the second radio frequency combining cell, or P2 may be allocated to the first radio frequency combining cell, and P1 may be allocated to the second radio frequency combining cell. For the adjacent pRRU, pRRU is already allocated to the radio frequency combined cell, then only the unallocated pRRU is allocated at this time, and when the unallocated pRRU is allocated, the radio frequency combined cell allocated by the adjacent pRRU is different from the radio frequency combined cell where the already allocated pRRU is located.

From the above allocation results, the number of uplink pRRU members in different radio frequency combined cells may be different. Of course, this is just one example, and the number of uplink pRRU members in different radio frequency combined cells may be the same. The number of uplink pRRU members in the radio frequency combined cell is determined by the positional adjacency relationship between the prrus and the order of allocation.

In the working process of the digitalized room division cells, the uplink transmission requirement is not met after a period of operation due to different distribution sequences of a plurality of pRRUs with adjacent relations, and the distribution sequences of the pRRUs can be adjusted to readjust uplink pRRU members in each radio frequency combining cell. As in the above embodiment, the allocation may be performed in the reverse order, with P2 and P6 allocated first, and then P3 and P5, P2 and P4, P1 and P3, and P1 and P2 allocated in sequence. At the time of allocation, a number of different allocations may occur.

When the allocation is carried out, P2 is allocated to a first radio frequency combining cell, and P6 is allocated to a second radio frequency combining cell; when the allocation is performed again, since P3 and P5 are not allocated to the corresponding radio frequency combining cells, P3 may be allocated to the first radio frequency combining cell, P5 may be allocated to the second radio frequency combining cell, and the subsequent adjacent unassigned prrus are allocated according to the rules described above, and the allocation results are shown in table 2. Such a distribution result is substantially the same as the distribution result in table 1. Because the composition of pRRU members in the first radio frequency combined cell before allocation does not meet the uplink transmission condition, and the composition of the uplink pRRU members in the second radio frequency combined cell after allocation is the same as the composition of the uplink pRRU members in the first radio frequency combined cell before allocation, the second radio frequency combined cell after allocation does not meet the uplink transmission condition, and needs to be allocated again. After adjustment, the uplink pRRU member composition of each of the N radio frequency combined cells is different from the uplink pRRU member composition before adjustment of the first radio frequency combined cell.

Radio frequency combining cell	First radio frequency combining cell	Second radio frequency combined cell
			Uplink pRRU member	P2，P3	P6，P5，P4，P1

TABLE 2

When the allocation is carried out, P2 is allocated to a first radio frequency combining cell, and P6 is allocated to a second radio frequency combining cell; when the allocation is performed, unlike the above allocation, P5 may be allocated to the first radio frequency combining cell, P3 may be allocated to the second radio frequency combining cell, and subsequent adjacent unassigned prrus may be allocated according to the foregoing rule, where the allocation results are shown in table 3. As can be seen from table 3, the allocation results are greatly different from those of tables 1 and 2, and the number of uplink pRRU members in the first radio frequency combined cell and the second radio frequency combined cell are the same.

Radio frequency combining cell	First radio frequency combining cell	Second radio frequency combined cell

TABLE 3 Table 3

Therefore, in the actual running process of the digitalized room sub-cell, it is necessary to monitor in real time whether each radio frequency combining cell reaches the uplink member adjustment condition, and if the uplink member adjustment condition is reached, adjust uplink pRRU members in the radio frequency combining cell. In order to achieve the purpose of adjustment, that is, to improve the uplink transmission capability of the digitalized indoor division cell, it should be ensured that the pRRU member in any radio frequency combining cell after adjustment is different from the pRRU member in the first radio frequency combining cell before adjustment.

As can be seen from the above adjustment procedure, when adjusting, the position adjacent relation between the prrus is known, and according to the position adjacent relation, when adjusting uplink pRRU members of each radio frequency combining cell in the digitizing room dividing cell, the prrus with adjacent positions are allocated to different radio frequency combining cells. The position adjacent relation among the pRRUs can be obtained by establishing a layout topological graph among the pRRUs according to the initial stage of the digital cell division layout and obtaining the position adjacent relation among the pRRUs according to the layout topological graph. However, when the uplink pRRU member is adjusted by the method, because the digitalized indoor division cells run for a long time, the uplink pRRU member in each radio frequency combined cell is adjusted for multiple times, and it is difficult to determine or even impossible to determine the corresponding relationship between the pRRU running in the digitalized indoor division cells and the pRRU in the layout topology map, so that the time required for adjustment is long or the adjustment result cannot reach the expectations.

In order to solve the above problems, the present application provides a method for adjusting uplink pRRU members of each radio frequency combining cell in a digitizing room cell. Referring to fig. 3, fig. 3 is a flowchart of an embodiment of a method for adjusting uplink pRRU membership of each radio frequency combining cell in a digitizing cell provided in the present application. The adjusting method comprises the following steps: s3-1: and starting signal polling of the first user equipment, so that the first user equipment transmits channel sounding reference signals to each of M pRRUs in the digital indoor cell, and acquiring measurement results of the channel sounding reference signals of the first user equipment and each of the M pRRUs respectively. The BBU may control a time at which the first user equipment transmits the channel sounding reference signal to the pRRU, and when the BBU starts the first user equipment signal poll, the first user equipment transmits the channel sounding reference signal to the pRRU. The method for the first ue to send the channel sounding reference signal to the pRRU is similar to measuring whether the first ue belongs to a ue connected to a certain pRRU. The method comprises the steps that a first user equipment sends an uplink subframe, wherein the last symbol user in the uplink subframe sends SRS. In specific implementation, the BBU may control the first user equipment to perform uplink transmission on the SRS symbol by only one pRRU, that is, close other RRUs and open only one pRRU on the SRS symbol.

S3-2: and determining N pRRUs nearest to the first user equipment according to a measurement result of the channel sounding reference signal to form a first pRRU set, wherein N is the number of radio frequency combining cells in the digital room dividing cells. Because the SRS transmitted by the first ue is transmitted on only one pRRU, the uplink reference signal received power (english: reference Signal Receiving Power, abbreviated: RSRP) of the SRS transmitted by the first ue through the pRRU is measured on the pRRU. For example, in the uplink subframe 1, only the first pRRU is turned on, so as to obtain the uplink RSRP of the first user equipment corresponding to the first pRRU; and so on, measuring the uplink RSRP of the first user equipment corresponding to each pRRU in the digital room partition cell. N pRRUs closest to the first user equipment are N pRRUs with the largest uplink RSRP of the first user equipment. In the above embodiment, we obtain the uplink RSRP of the first user equipment corresponding to each pRRU, and of course, other measurement indexes may also be selected, and reference signal receiving quality (english: reference Signal Receiving Quality, abbreviated as RSRQ) may be obtained, so as to obtain the uplink RSRQ of the first user equipment corresponding to the first pRRU; and so on, measuring the uplink RSRQ of the first user equipment corresponding to each pRRU in the digital room partition cell. N pRRUs closest to the first user equipment are N pRRUs with the best uplink RSRQ quality of the first user equipment. The measurement index may also be an Arrival Time (Time of Arrival, abbreviated as TOA) of the channel sounding reference signal, i.e., N prrus closest to the first ue, i.e., N prrus with the shortest uplink TOA Time of the first ue. The present invention is not limited to the measurement index of the channel sounding reference signal, and will be described below by taking RSRP as an example for convenience of description.

S3-3: and distributing pRRUs in the first pRRU set to different radio frequency combining cells. When pRRU in the first set of prrus is allocated, its allocation method is the same as in the previous embodiment. If none of the prrus in the first pRRU set is allocated to the corresponding radio frequency combining cell, the prrus in the first pRRU set may be allocated to the radio frequency combining cell in any corresponding relationship. If a plurality of pRRUs in the first pRRU set are already allocated to the corresponding radio frequency combining cells, only the unallocated pRRUs are allocated, and when the unallocated pRRUs are allocated, the allocated radio frequency combining cells are different from the radio frequency combining cells where the already allocated pRRUs are located.

By the method, the first pRRU set formed by N pRRUs closest to the first user equipment can be determined, and N pRRUs adjacent in position can be determined. The positional adjacency between pRRU determined by this method is immediate and accurate. When N pRRUs closest to a plurality of user equipment are allocated by adopting the same method, adjacent pRRUs can be allocated to different radio frequency combining cells again, and the purpose of improving the uplink transmission capacity of each position is achieved. Of course, in some cases, if some prrus are not covered in the N nearest prrus of all the ue, it is indicated that the prrus are not connected to the ue, and the allocation of the prrus to a certain radio combining cell has less influence on improving the uplink transmission capability of the tdma cell. For the pRRUs, a random allocation mode can be adopted to allocate the pRRUs to different radio frequency combining cells; these prrus may also still be allocated to the original radio frequency combined cell and not adjusted.

From the uplink pRRU members in the radio frequency combined cells in tables 1, 2 and 3, it can be seen that, eventually, the uplink pRRU members in each radio frequency combined cell are related to the allocation order in addition to the positional adjacency relationship between prrus. According to the adjustment method in fig. 3, each ue will obtain a set of N pRRU closest to it. When a plurality of user equipment exist, a plurality of pRRU sets are obtained, and the sequence of allocation of the plurality of pRRU sets influences uplink pRRU members in each radio frequency combining cell finally. Therefore, how to determine the order of allocation of the plurality of pRRU sets is important.

Referring to fig. 4, fig. 4 is a flowchart of another embodiment of a method for adjusting uplink pRRU membership of each radio frequency combining cell in a digitizing cell provided in the present application. The adjusting method comprises the following steps: s4-1: and determining measurement results of channel sounding reference signals between X user equipment and M pRRUs in the digital indoor partition cell. The BBU starts signal polling among the X user equipments, where the X user equipments may be all user equipments currently connected to the digitizing cell, or may be part of the user equipments in the digitizing cell. The X user equipments respectively transmit channel sounding reference signals to M prrus in the digitalized ventricular cell. And the BBU performs uplink transmission on the SRS symbol according to a certain user equipment, and obtains a measurement result of a channel sounding reference signal between the user equipment and the pRRU, or takes RSRP as an example. The uplink channel quality between X user equipments and M prrus is obtained as shown in table 4.

S4-2: and determining Y pRRU sets according to N pRRUs nearest to each of the X user equipment, wherein Y is less than or equal to X. In some cases, the most recent N prrus corresponding to the plurality of user equipments may be the same, for example, members in the pRRU set determined by the first user equipment, the second user equipment, and the third user equipment are the same, for example, pRRU1, pRRU3, and pRRU6 are recorded as a first pRRU set; the members in the pRRU set determined by the fourth user equipment and the fifth user equipment are the same, for example, pRRU2, pRRU4 and pRRU5 are denoted as a second pRRU set, and thus, finally, the number of pRRU sets determined by the X user equipments is X or less.

S4-3: and counting the number of user equipment corresponding to each of the Y pRRU sets. And if the pRRU sets determined by the first user equipment, the second user equipment and the third user equipment are all the first pRRU sets, the first user equipment, the second user equipment and the third user equipment are called as user equipment corresponding to the first pRRU sets, and the number of the user equipment corresponding to the first pRRU sets is 3. Similarly, the number of user equipments corresponding to each of the Y pRRU sets is counted, as shown in table 5.

TABLE 5

S4-4: and distributing pRRU members in the pRRU set according to the sequence of the number of the user equipment corresponding to the pRRU set from large to small. In one embodiment, the first pRRU set is the pRRU set with the largest number of corresponding user equipments, and the pRRU members in the first pRRU set are allocated first. Assuming that the digitizing cell includes a total of 4 radio frequency combined cells, pRRU members in the first pRRU set are pRRU1, pRRU3, pRRU4, and pRRU9, respectively, pRRU1 is assigned to radio frequency combined set 1, pRRU3 is assigned to radio frequency combined set 2, pRRU4 is assigned to radio frequency combined set 3, and pRRU9 is assigned to radio frequency combined set 4. And if the second pRRU set is the pRRU set with a plurality of times corresponding to the user equipment, after the pRRU members in the first pRRU set are allocated, allocating the pRRU members in the second pRRU set. The pRRU members in the second pRRU set are pRRU1, pRRU2, pRRU7 and pRRU6, respectively, since pRRU1 has already been allocated, this time will no longer be allocated, other pRRU members in the second pRRU set are allocated to radio frequency-combined rentals cells different from pRRU1, in one embodiment pRRU2 is allocated to radio frequency-combined set 2, pRRU7 is allocated to radio frequency-combined set 3, and pRRU6 is allocated to radio frequency-combined set 4. And by analogy, sequentially distributing pRRU members in the pRRU set according to the number of user equipment corresponding to the pRRU set from large to small. Of course, when the pRRU sets are allocated in sequence, all the pRRU sets may be allocated, or only the pRRU set with the top order may be allocated, for example, only the pRRU set with the top three in sequence may be allocated, for example, the first pRRU set, the third pRRU set, and the fourth pRRU set are the first, second, and third pRRU sets corresponding to the number of user equipments, respectively, and then only the first pRRU set, the third pRRU set, and the fourth pRRU set may be allocated.

Referring to fig. 5, fig. 5 is a flowchart of another embodiment of a method for adjusting uplink pRRU membership of each radio frequency combining cell in a digitizing cell provided in the present application. The adjusting method comprises the following steps: s5-1: and determining measurement results of channel sounding reference signals between X user equipment and M pRRUs in the digital indoor partition cell. S5-2: and determining Y pRRU sets according to N pRRUs nearest to each of the X user equipment, wherein Y is less than or equal to X. The methods adopted by S5-1 and S5-2 are the same as those of S4-1 and S4-2, and the purpose achieved is the same, and the details are not repeated here.

S5-3: and counting the uplink PRB utilization rate of the user equipment corresponding to each of the Y pRRU sets. And taking one pRRU set as a unit, counting the corresponding uplink PRB utilization rate, wherein the counting method is the same as that of the previous counting of the uplink PRB utilization rate of the radio frequency combining cell, and the details are not repeated here. The uplink PRB utilization of the user equipment corresponding to each of the Y pRRU sets is obtained, as shown in table 6.

TABLE 6

S5-4: and distributing pRRU members in the pRRU set according to the sequence of the uplink PRB utilization rate of the user equipment corresponding to the pRRU set from large to small. In an embodiment, the third pRRU set is a pRRU set with the highest uplink PRB utilization rate corresponding to the number of user equipments from among the Y pRRU sets, and then pRRU members in the third pRRU set are allocated first. And if the fourth pRRU set is a pRRU set with the next highest uplink PRB utilization rate of the corresponding user equipment in the Y pRRU sets, after pRRU member allocation in the third pRRU set is completed, pRRU members in the fourth pRRU set are allocated. And by analogy, sequentially distributing pRRU members in the pRRU set according to the uplink PRB utilization rate of the user equipment corresponding to the pRRU set from large to small. The method for assigning pRRU members in the pRRU set is the same as the previous assignment method, and will not be described here. Similarly to the foregoing, when pRRU sets are allocated sequentially, all pRRU sets may be allocated, or only pRRU in the preceding sequence may be allocated.

It can be understood that the methods in fig. 4 and fig. 5 may be used simultaneously, that is, the number of user equipments and uplink PRB utilization rate corresponding to each of the Y pRRU sets are counted simultaneously, and the pRRU sets with higher number of user equipments and higher uplink PRB utilization rate are preferentially allocated.

By the method for adjusting uplink pRRU members of each radio frequency combining cell in the digitizing room dividing cell in fig. 4 and fig. 5, the pRRU set with the largest corresponding user equipment can be preferentially allocated, or the pRRU set with the highest uplink PRB utilization rate of the corresponding user equipment can be preferentially allocated, the position in the user set or the position with larger user resource consumption can be determined, a plurality of radio frequency combining cells are included, the uplink transmission capacity of the positions with higher uplink capacity requirements is improved, and the uplink transmission capacity of the whole digitizing room dividing cell is further improved.
