1 is a diagram showing an example of a relay service system according to an embodiment of the present invention.

Referring to FIG. 1, the relay service system 10 of the present invention includes a control server device 100 (eg, a central unit), a distribution device 200 (DU-h, distributed unit higher layer), and a layer splitting device 300. ), may include a plurality of nodes 400 (eg, radio unit (RU)).

The control server device 100 is directly or indirectly connected to at least one of the distribution device 200, the layer split device 300, and a plurality of nodes 400, and is Building communication services can be supported. For example, the control server device 100 may collect connection information (eg, node identification information, etc.) of the layer split device 300 from the distribution device 200. The control server device 100 provides the layer split device 300 with information necessary to derive an UL gain weighting factor (eg, connection information of lower nodes (eg, port identification information, the number of port lower nodes). Etc.), cell information (eg, port identification information, copy cell availability, etc.), uplink noise level per layer split port, etc.) can be collected. The control server device 100 derives an uplink gain weight factor based on the collected information, and at least one of an uplink and a downlink of lower nodes (eg, high-power wireless devices or small-power wireless devices) Can control the output of. In this regard, the control server device 100 connects the current uplink gain for each path, the current downlink output for each path, and information of lower nodes (eg, noise identification information) to the layer splitting device 300. It can be obtained from the nodes 400. To this end, the control server device 100 may be connected to the distribution device 200, the layer split device 300, and a plurality of nodes 400.

As described above, the control server device 100 according to the present invention provides a plurality of remote radio units (RRUs) (large power, small power, and the plurality of nodes 400) disposed in the same cell in terms of efficient coverage expansion. Correspondence), by adjusting the output gain of the high-power wireless device (e.g., a relatively high-powered wireless device) and a low-power wireless device (e.g., a relatively low-powered wireless device) by mixing the UL noise level between devices By minimizing the difference, the influence of the UL noise level between high-power/low-power radio devices can be adjusted or removed to a minimum (or less than a specified value). In this regard, the control server device 100 is the information of the connected layer split device 300 (eg, LS (Layer Split)) and a plurality of nodes (eg, high power wireless device, small power wireless device)). With reference to, the uplink gain values of the plurality of lower nodes 400 (high power wireless devices, low power wireless devices) may be derived, and uplink gain control of the plurality of nodes 400 may be performed.

The distribution device 200 transmits the data received from the control server device 100 in connection with the operation of the 5G communication service to the layer split device 300, and the plurality of nodes 400 collected by the layer split device 300 The signal transmitted by) may be transmitted to the control server device 100. For example, the distribution device 200 includes information defined in a user plane (UP), radio specific control information (eg, time critical or radio specific control information), and general control information (as general control control information, link setup and control information). , Control and management information can be delivered. In addition, the distribution device 200 may support a back-how in a given area.

The layer splitting device 300 may be disposed between the distribution device 200 and a plurality of nodes 400. The layer splitting device 300 may include a plurality of ports. The plurality of ports may be grouped in the same cell unit. Alternatively, the plurality of ports may be grouped by zone or by floor within the in-building. Accordingly, the cell may be defined as, for example, one floor or one area in a building. The layer splitting device 300 includes the number of interlocking nodes 400 for each port, an uplink gain and a downlink gain of each end node 400, an uplink noise level at each port, and each end node ( At least one of the output information of 400) may be collected.

The plurality of nodes 400 may include wireless devices that support communication services based on different outputs. For example, the plurality of nodes 400 may include a high-power wireless device (eg, 46dBm) and a low-power wireless device (eg, 24dBm). When the plurality of nodes 400 having different outputs are accommodated in the same cell, each up link noise sum may occur. At this time, because of the large UL Gain of the high-power wireless device, the UL noise of the small-power wireless device increases relatively high. For example, if the UL Gain of a high-power wireless device is 37dB and the UL Gain of a low-power wireless device is 30dB, the UL noise of the low-power wireless device increases by 7dB due to the high UL Gain of the large-power wireless device, and the low-power wireless device If the UL Noise of 7dB increases, the UL coverage of the low-power wireless device decreases.

Alternatively, the communication interface 110 may collect uplink noise levels from a plurality of nodes 400 under the control of the processor 120.

The noise information collection unit 121 may collect uplink noise level information for each port located in the same cell from the layer splitting device 300 through the communication interface 110. For example, the noise information collection unit 121 may collect the uplink noise level information according to a predetermined period. Alternatively, when a change in the connection state of the nodes 400 occurs, such as when a new lower node is added to a specific port or a lower node connected to a specific port is removed, the uplink noise for each port Level information can be collected. In this case, the noise information collection unit 121 may collect information on the number of nodes 400 connected for each port together.

The uplink gain adjuster 123 may calculate an uplink gain weight factor for coverage optimization based on the collected information on the number of nodes 400 and the uplink noise level information for each port. For example, the uplink gain adjuster 123 adjusts the uplink noise level of all nodes 400 to a specified value by adjusting the uplink gain of relatively high output devices according to a predefined policy. It can generate a signal (eg, a control signal that minimizes the uplink noise level). Alternatively, the uplink gain adjustment unit 123 may calculate an average value of the uplink noise level for each port, and may calculate an uplink gain adjustment value for each port to have the calculated average noise level. Alternatively, the uplink gain adjustment unit 123 maintains a specified value for the output of a specific port or a specific wireless device, and generates a control signal for adjusting the output of another port or other wireless device to maintain the output of the layer splitting device ( 300) or a plurality of nodes 400.

When the uplink gain adjustment unit 125 generates a control signal for adjusting the uplink gain of the nodes 400, the downlink gain adjustment unit 125 determines a downlink gain adjustment value corresponding to the control signal. The generated downlink gain adjustment value may be provided to the layer split device 300 (or a plurality of nodes 400 connected to the layer split device 300) together with the uplink gain adjustment value. The downlink gain adjustment value may be, for example, the same value as the uplink gain adjustment value.

Level information can be collected. In this operation, the processor 120 may collect the number of nodes 400 for each port and output information of the nodes 400, and calculate an uplink gain weight factor based on this.

In step 303, the processor 120 may select a port to reduce the uplink output based on the collected uplink noise level information. In this operation, the processor 120 may determine a port selection to which the gain (or output) is to be reduced in consideration of the calculated uplink gain weight factor.

In step 305, the processor 120 generates an uplink gain adjustment signal of a port to which the uplink output is to be reduced, and provides the corresponding signal to the layer splitting device 300 to adjust the uplink gain of a specific port. . In this regard, the layer splitting apparatus 300 may check an uplink gain value to be adjusted and a node, and transmit an uplink gain value to be adjusted to a specific node.

As another example, the processor 120 of the control server device 100 collects information on the uplink output level from nodes 400 connected to each port in the same cell, and based on this, the uplink gain value to be adjusted And the uplink gain value to be adjusted may be transmitted to a specific node.

In step 403, the processor 120 classifies the collected uplink noise level information for each cell, and calculates an average uplink noise level value for each cell.

In step 405, the processor 120 may determine a port to adjust the output in the same cell based on the calculated average value.

In step 407, the processor 120 may generate and provide a control signal to be provided to the determined ports. For example, the processor 120 controls the output to be reduced to the average value for a port with a higher output based on the average value, and controls the output to be increased to match the average value for a port with a lower output. Can generate a control signal. The processor 120 may provide the generated control signal to the layer splitting device 300 to control the uplink gain of each port to be adjusted.

In step 503, the processor 120 may check whether there is a set value set to maintain the uplink output above a specified value. In this regard, the control server device 100 may further include a memory to store setting information specifying an uplink output of a specific port. When the timing of adjusting the uplink gain of the port comes, the processor 120 may check the memory to determine whether there is pre-stored setting information.

In step 503, if there is no configuration information, the processor 120 branches to step 505 and operates for uplink gain adjustment according to a specified policy (eg, the uplink gain adjustment policy described in FIG. 3 or 4 described above). Can be done.

In step 503, if there is setting information, in step 507, the processor 120 maintains the uplink output of the port according to the setting information, while controlling the uplink noise of another port to a specified value (eg; Control signals to minimize uplink noise on other ports) can be generated.

In step 509, the processor 120 may provide the control signal to the layer splitting device 300 to adjust an uplink gain so that uplink noise of a port without configuration information can be minimized. Alternatively, the processor 120 may control to adjust the uplink gain by providing the control signal to nodes of ports without configuration information.
