Fig. 1 is a schematic diagram of some embodiments of an active room subsystem of the present disclosure. The active indoor system includes a centralized processing Unit 110, a distributed processing Unit 120, and a Radio Remote Unit (pRRU) 130.
The centralized processing unit 110 is configured to complete RRC (Radio Resource Control) layer functions and PDCP (Packet Data Convergence Protocol) layer functions.
Since the centralized processing unit 110 only needs to complete the RRC layer function and the PDCP layer function of the system, the complexity of the centralized processing unit 110 is effectively reduced, and therefore, the centralized processing unit can be implemented by using a low-performance general-purpose server. The cost is reduced, and meanwhile, the expansibility of the system can be effectively improved.
The distributed processing unit 120 is configured to perform an RLC (Radio Link Control) layer function, an MAC (Media Access Control) layer function, and a PHY-H (Physical-layer-high) layer function.
The distributed processing unit 120 is utilized to complete the functions of RLC, MAC, PHY-H, etc., so that the burden of the centralized processing unit can be effectively reduced, and the time delay is lower due to the closer proximity to the user.
The radio remote unit 130 is configured to perform PHY-L (Physical-L) layer functions, radio frequency related functions, and calculation functions, wherein the calculation unit 131 located in the radio remote unit is configured to calculate an instantaneous capacity between the radio remote unit and the distributed processing unit, and adjust a linear operation region located in the power amplifier according to the instantaneous capacity. The remote radio unit 130 may further include a CFR (peak factor reduction) function and a filtering function.
The remote radio unit 130 performs PHY-L functions, reducing the capacity requirement between the distributed processing unit and the remote radio unit.
The instantaneous capacity is, for example, instantaneous traffic including, for example, data throughput, the number of connected users, the number of activated users, the number of voice calls, and the like. In some embodiments, the greater the instantaneous capacity, the greater the linear operating region of the power amplifier. After the active room subsystem is started and stably works, the active room subsystem is in no-load at the moment, the linear working area of the power amplifier of the radio remote unit is in a lower gain range, at the moment, the computing unit monitors the real-time data volume between the radio remote unit and the distributed processing unit, when a user gradually accesses and initiates a service, the real-time data volume is gradually increased, and the gain of the power amplifier is increased by increasing the linear working area of the power amplifier, so that the access requirement of the user is met; when the user initiates service reduction, the real-time data volume is gradually reduced, and the gain of the power amplifier is reduced by reducing the linear working area of the power amplifier, so that the user access requirement can be met.
The power amplifier outputs the same power, and if the power amplifier operates in a nonlinear operating region and the efficiency of the power amplifier is low, the input power needs to be increased, which results in increased power consumption.
In this embodiment, the computing unit in the remote radio unit computes the instantaneous capacity between the remote radio unit and the distributed processing unit, and adjusts the linear operating region in the power amplifier according to the instantaneous capacity, so that the power amplifier operates in a high-efficiency region, the power consumption of the remote radio unit can be reduced, and the power consumption of the whole active room subsystem is further reduced.
On the other hand, the indoor network coverage is realized by adopting a three-level architecture of the centralized processing unit, the distributed processing unit and the remote radio unit, so that the cost is reduced, the performance is improved, the future smooth upgrade of the equipment is realized, the transmission rate is obviously improved, the indoor high-speed internet access requirement of people is met, and the floor popularization of 5G is promoted.
In other embodiments of the present disclosure, the calculating unit 131 is further configured to send the calculated instantaneous capacity between the radio remote unit 130 and the distributed processing unit 120 to the distributed processing unit 110; the distributed processing unit 120 is configured to count the instantaneous capacity sent by the calculating unit 131 of the plurality of remote radio units 130, obtain the total cell capacity, and send the total cell capacity to the centralized processing unit 110; the centralized processing unit 110 is configured to determine whether to perform cell splitting or cell merging according to the total cell capacity, and transmit the processing result to the distributed processing unit 120.
The distributed processing unit 120 is configured to, if receiving the cell splitting message sent by the centralized processing unit 110, group the plurality of remote radio units 130 according to the number of split cells, and allocate a cell identifier to each group of remote radio units 130; if the cell merging message sent by the centralized processing unit 110 is received, the identities of the plurality of radio remote units 130 are modified to the identities of the merged cells.
A centralized processing unit 110 may be connected to a plurality of distributed processing units 120, each distributed processing unit 120 may be connected to a plurality of remote radio units 130, after the active indoor subsystem is powered on and operates stably, and at this time, the active indoor subsystem is idle, the plurality of remote radio units 130 under the same distributed processing unit 120 belong to the same cell, but as more users access and initiate services, the digital merge function of the distributed processing unit 120 can count the total capacity of the whole cell, when the total capacity of the cell is greater than a threshold, the centralized processing unit 110 determines a cell splitting decision, and the distributed processing unit 120 groups the plurality of remote radio units 130 according to the number of split cells, for example, if the cell split includes a cell a1 and a cell a2, a part of the remote radio units are assigned to a cell a1, and a part of the remote radio units are assigned to a cell a 2.
If multiple radio remote units 130 under the same distributed processing unit 120 belong to different cells, when the total cell capacity is smaller than the threshold, the centralized processing unit 110 determines a cell merging decision, and the distributed processing unit 120 modifies the identifiers of the multiple radio remote units 130 into the identifier of the merged cell.
In the above embodiment, the digital combining function is placed on the distributed processing unit, so that the performance of combining and splitting the system cells is improved, the power consumption of the radio remote unit is reduced, and the running state of the system is adjusted according to the actual situation, so that the power consumption of the system is reduced.

In some embodiments, the centralized processing unit performs cell splitting when determining that the total cell capacity is greater than a threshold, and performs cell merging when determining that the total cell capacity is less than the threshold.
In step 340, if the distributed processing unit receives the cell splitting message sent by the centralized control unit, the distributed processing unit groups a plurality of remote radio units according to the number of the split cells, and allocates a cell identifier to each group of remote radio units; and if receiving a cell merging message sent by the centralized control unit, modifying the identifiers of the radio remote units into the identifiers of the merged cells.
