[0071] The specific implementation manners of the present application will be described below by way of example in conjunction with the accompanying drawings in the embodiments of the present application. However, the implementation manners of the present application can also include combinations of these embodiments without departing from the spirit or scope of the present application, such as using other embodiments and making structural changes. Therefore, the following detailed description of the embodiments should not be interpreted in a limiting sense. The terms used in the embodiment section of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0072] FIG. 2 shows a possible, non-limiting system diagram. As shown in FIG. 2, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (such as 110a and 110b in FIG. 2, collectively referred to as 110) and at least one terminal (such as 120a-120j in FIG. 2, collectively referred to as 120). Other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 2), etc. can also be included in the RAN 100. The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be different physical devices respectively, or can be the same physical device integrated with the logical functions of the core network and the logical functions of the radio access network.

[0073] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, e.g., a 4G, 5G mobile communication system, or a future evolution of the same. The RAN 100 can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN). The RAN 100 can also be a communication system that combines two or more of the above systems.

[0074] The RAN node 110, which can also be referred to as an access network device, a RAN entity or an access node, etc., forms part of the communication system and is responsible for enabling wireless access to the communication system by terminals. The RAN nodes 110 in the communication system can be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, e.g., the network element 120i in Figure 2 can be a helicopter or a drone, which can be configured to be a mobile base station. For a terminal 120j that accesses the RAN 100 via the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. Both the RAN node 110 and the terminal 120 are sometimes referred to as communication apparatuses, e.g., the network elements 110a and 110b in Figure 2 can be understood as communication apparatuses with base station functionalities, and the network elements 120a-120j can be understood as communication apparatuses with terminal functionalities. For the convenience of description, the RAN node is referred to as an access network device hereinafter.

[0075] In a possible scenario, the access network device can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a base station in a future mobile communication system, etc. The RAN node can be a macro base station (e.g., 110a in Figure 2), a micro base station or an indoor station (e.g., 110b in Figure 2), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in vehicle to everything (V2X) technology can be a road side unit (RSU).

[0076] A possible structure of an access network device is shown in FIG. 3. The access network device can include one or more centralized units (CU) and one or more distributed units (DU). The access network device can also include one or more radio units (RU). For clarity, only one CU, DU and RU are shown in FIG. 2. The CU can also be divided into CU-control plane (CP) and CU-user plane (UP), which is not limited in the present application. The CU and the DU can be separately arranged or included in the same network element, such as a BBU. The RU can be included in a radio frequency device or a radio frequency unit, such as an RRU, an active antenna unit (AAU) or a remote radio head (RRH).

[0077] The CU (or CU-CP and CU-UP), DU or RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in the present application. Any of the CU (or CU-CP, CU-UP), DU and RU in the present application can be implemented by a software module, a hardware module or a combination of a software module and a hardware module.

[0078] It can be understood that in the present application, the communication between the BBU and the AAU can also be replaced by the communication between the DU and the RU.

[0079] The CU is responsible for processing non-real-time protocols and services, implements radio resource control (RRC), and functions of a packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services, implements functions of a radio link control (RLC) layer, a media access control (MAC) layer, and a physical (PHY) layer. The RU implements part of the physical layer processing function, radio frequency processing, and related functions of an active antenna. The above configuration of the CU, the DU, and the RU is merely an example, and the CU, the DU, and the RU can be configured to have functions as needed.

[0080] Any of the CU (or CU-CP, CU-UP), the DU, and the RU in the present application can be implemented by a software module, a hardware module, or a combination of the software module and the hardware module.

[0081] The FDD LNR, which can also be referred to as LNR uplink and downlink spectrum sharing, refers to sharing of LTE cells and NR cells on the same spectrum resource through time division and frequency division. Specifically, in the time domain, instantaneous sharing is supported with a period of 1 ms, that is, coordination scheduling of spectrum resources can be performed once every 1 ms. In the frequency domain, dynamic sharing is supported with a granularity of 1 resource block (RB), and dynamic resource allocation is performed according to the traffic demand of the LTE cell and the traffic demand of the NR cell. In addition, a spectrum sharing cell set can be set, and the LTE cell and the NR cell added to the spectrum sharing cell set can share resources on the same spectrum.

[0082] Before the LTE cell and the NR cell share the spectrum, the channel power of the shared spectrum resource needs to be determined, and in addition, the RRU needs to determine whether the remaining power of the RRU can support the channel power of the shared spectrum resource. If the remaining power is sufficient, the BBU determines that the demand for the channel power of the shared spectrum resource can be met.

[0083] Because the LTE cell and the NR cell of the DSS can be configured with power parameters respectively, for example, the respective channel powers of the shared spectrum resource are configured, there can be a problem of waste of the channel power allocated by the RRU for the shared spectrum resource.

[0084] For example, if the bandwidth of the shared spectrum resource is 20M, the LTE cell configures a corresponding channel power of 20W for the shared spectrum resource, and the NR cell configures a corresponding channel power of 20W for the shared spectrum resource, then the RRU allocates a channel power of 40W for the shared spectrum resource according to the above configuration, and in the process of dynamic spectrum sharing, only part of the channel power may be needed, for example, 20W, and then there will be a problem of waste of power allocation and power use.

[0085] As shown in FIG. 4, the middle area represents the wasted power of the RRU. As can be seen from FIG. 4, the power of the RRU is wasted seriously, because the LTE cell and the NR cell both request the RRU to configure a channel power of 20W for them on the shared spectrum resource, and the RRU allocates a power of 40W for the shared spectrum resource, while the channel power actually needed to fully use the shared spectrum resource in the process of dynamic spectrum sharing is only 20W, and the extra 20W power cannot be used.

[0086] To solve the problem of waste of power allocation by the RRU for the shared spectrum resource, the present application provides a spectrum sharing method to realize reasonable configuration of the channel power of the shared spectrum resource by the RRU and efficient use of power. The following method is introduced by taking the RRU and the BBU as examples. In addition, it should be understood that the RRU can also be replaced by a chip, unit or module with the function of the RRU. The BBU can also be replaced by a chip, unit or module with the function of the BBU.

[0087] The first cell and the second cell described below can be cells of the same type or cells of different types. For example, the first cell and the second cell are cells of the same radio access technology (RAT) type or cells of different RAT types. For example, the first cell is an LTE cell and the second cell is an NR cell, or the first cell is an LTE cell and the second cell is an LTE cell, or the first cell is an NR cell and the second cell is an NR cell, or the first cell is an NR cell and the second cell is a future communication system cell, etc., and the present application does not limit the RAT types corresponding to the first cell and the second cell respectively. In addition, the first cell and the second cell can be two cells under the same base station, or the first cell and the second cell belong to different base stations.

[0088] The possible application scenarios of the embodiments of the present application are introduced as follows:

[0089] Possible application scenario A, the first BBU is a BBU corresponding to the first cell. The second BBU is a BBU corresponding to the second cell. The first BBU can also be replaced by a first baseband board, or a first universal baseband processing board (UBBP). The second BBU can also be replaced by a second baseband board, or a second UBBP. As shown in FIG. 5A, the first UBBP can communicate with the RRU, and the second UBBP can communicate with the RRU.

[0090] Possible application scenario B, the first cell and the second cell correspond to the same BBU. As shown in FIG. 5B, the UBBP can communicate with the RRU.

[0091] In addition, in FIG. 5A and FIG. 5B, a universal main processing & transmission unit (UMPT) is also included. The UMPT can perform coordinated dynamic allocation of shared frequency domain resources and power for the first cell and the second cell after determining the channel power of the shared spectrum resources. For details, please refer to the related content below.

[0092] In this application, the shared frequency domain resources, the shared spectrum resources, and the shared spectrum can be replaced with each other. The non-shared frequency domain resources, the private frequency domain resources, the private spectrum resources, and the private spectrum can be replaced with each other.

[0093] As shown in FIG. 6, the method includes:

[0094] 600, the RRU receives the first information and the second information.

[0095] Exemplarily, in combination with the above-mentioned possible application scenario A, the RRU receives the first information sent by the first BBU, and receives the second information sent by the second BBU. In combination with the above-mentioned possible application scenario B, the RRU receives the first information and the second information sent by the BBU.

[0096] The first information indicates the first frequency domain resource and the power configuration of the first cell, and the second information indicates the second frequency domain resource and the power configuration of the second cell. The power configuration of the first cell indicates the channel power of the total frequency domain resource of the first cell, the power configuration of the second cell indicates the channel power of the total frequency domain resource of the second cell, the total frequency domain resource of the first cell includes the first frequency domain resource, and the total frequency domain resource of the second cell includes the second frequency domain resource.

[0097] The first information indicates the first frequency domain resource, which can be understood as indicating at least two of a starting frequency domain position of the first frequency domain resource, a bandwidth of the first frequency domain, or an ending frequency domain position of the first frequency domain resource. Similarly, the second information indicates the second frequency domain resource, which can be understood as indicating at least two of a starting frequency position of the second frequency domain resource, a bandwidth of the second frequency domain resource, or an ending position of the second frequency domain resource.

[0098] In addition, in a possible implementation, the O-DU can address the LTE endpoint in the O-RU through an LTE dedicated identifier, and the O-DU can address the NR endpoint in the O-RU through an NR dedicated identifier, that is, the LTE dedicated identifier indicates the frequency domain resource allocated for the LTE cell, and the NR dedicated identifier indicates the frequency domain resource allocated for the NR cell. Here, the frequency domain resource is one or more PRBs, or one carrier, or one frequency band, and the like, which are not limited in the present application.

[0099] For example, if the first cell is an LTE cell and the second cell is an NR cell, the first information includes an LTE dedicated identifier, the second information includes an NR dedicated identifier, the frequency domain resource indicated by the LTE dedicated identifier is the first frequency domain resource, and the frequency domain resource indicated by the NR dedicated identifier is the second frequency domain resource. If the first cell is an NR cell and the second cell is an LTE cell, the first information includes an NR dedicated identifier, the second information includes an LTE dedicated identifier, the frequency domain resource indicated by the NR dedicated identifier is the first frequency domain resource, and the frequency domain resource indicated by the LTE dedicated identifier is the second frequency domain resource.

[0100] In another possible implementation, the O-DU can address the LTE endpoint and the NR endpoint in the O-RU through a shared identifier, that is, the shared identifier indicates that the frequency domain resource is allocated for the LTE cell and the NR cell, and in addition, the frequency domain resource is indicated by an extended identifier to be shared by the LTE cell and the NR cell. Here, the frequency domain resource is one or more PRBs, or one carrier, or one frequency band, and the like, which are not limited in the present application.

[0101] For example, if the first cell is an LTE cell and the second cell is an NR cell, or if the first cell is an NR cell and the second cell is an LTE cell, the first information includes a shared identifier, the second information includes a shared identifier, and the frequency domain resource indicated by the shared identifier is the first frequency domain resource and the second frequency domain resource.

[0102] In some possible embodiments, the power configuration of the first cell indicates the channel power of the total frequency domain resource of the first cell, which can also be described as the channel power of the total bandwidth corresponding to the first cell, or can also be replaced by the channel power of a unit frequency domain resource in the total frequency domain resource corresponding to the first cell, for example, the channel power of a unit frequency domain resource in the total frequency domain resource corresponding to the first cell can be the channel power of a unit bandwidth corresponding to the first cell. The power configuration of the second cell is similar to that of the first cell, which will not be described here.

[0103] For example, assuming that the bandwidth of the total frequency domain resource of the first cell is 20M, the power configuration of the first cell can indicate that the channel power of the total frequency domain resource of the first cell is 20W, or the power configuration of the first cell can indicate that the channel power of a unit bandwidth corresponding to the first cell is 1W.

[0104] 610. The RRU determines the channel power of the shared frequency domain resource according to the first information and the second information.

[0105] For example, before the RRU determines the channel power of the shared frequency domain resource according to the first information and the second information, the RRU can also perform the following judgment according to the first information and the second information:

[0106] Possible implementation manner a: the first information further includes a first identifier, the first identifier being used to indicate a first frequency spectrum range, and the frequency spectrum range corresponding to the total frequency domain resource of the first cell belonging to the first frequency spectrum range. The second information further includes a second identifier, the second identifier being used to indicate a second frequency spectrum range, and the frequency spectrum range corresponding to the total frequency domain resource of the second cell belonging to the second frequency spectrum range.

[0107] Before determining the channel power of the shared frequency domain resource according to the first information and the second information, the RRU judges whether the first identifier and the second identifier are the same, and if so, the RRU determines the channel power of the shared frequency domain resource according to the first information and the second information. That is, in the case that the frequency spectrum range corresponding to the total frequency domain resource of the first cell and the frequency spectrum range corresponding to the total frequency domain resource of the second cell do not belong to the same frequency domain range, the first frequency domain resource and the second frequency domain resource will not have an intersection.

[0108] Through the above possible implementation manner a, the RRU can judge whether the frequency spectrum range corresponding to the total frequency domain resource of the first cell and the frequency spectrum range corresponding to the total frequency domain resource of the second cell belong to the same frequency domain range before determining the channel power of the shared frequency domain resource, and if so, further determine the shared frequency domain resource and the channel power of the shared frequency domain resource.

[0109] Possibility b: the first information further comprises first indication information, the first indication information is used to indicate the power allocation strategy of the first cell; the second information further comprises second indication information, the second indication information is used to indicate the power allocation strategy of the second cell.

[0110] The power allocation strategy of the first cell indicates shared power or exclusive power. When the power allocation strategy of the first cell indicates shared power, it means that the first cell agrees to share power with other cells, or in other words, the first cell agrees to share the channel power of the total frequency domain resource of the first cell with other cells. When the power allocation strategy of the first cell indicates exclusive power, it means that the first cell does not agree to share power with other cells, or in other words, the first cell does not agree to share the channel power of the total frequency domain resource of the first cell with other cells.

[0111] Before determining the channel power of the shared frequency domain resource according to the first information and the second information, the RRU judges whether the power allocation strategy of the first cell and the power allocation strategy of the second cell are both shared power. If so, the RRU determines the channel power of the first frequency domain resource according to the first information and the second information. That is, if at least one of the power allocation strategy of the first cell or the power allocation strategy of the second cell indicates exclusive power, the cell whose power allocation strategy indicates exclusive power does not support FDD LNR.

[0112] Exemplarily, the shared frequency domain resource can be determined according to the first frequency domain resource and the second frequency domain resource, the channel power of the shared frequency domain resource can be determined according to one or more of the shared frequency domain resource, the power configuration of the first cell and the power configuration of the second cell, and the channel power of the shared frequency domain resource is less than or equal to the maximum value of the channel power of the total frequency domain resource of the first cell and the channel power of the total frequency domain resource of the second cell. The shared frequency domain resource and the channel power of the shared frequency domain resource are described as follows:

[0113] I. Shared frequency domain resource

[0114] Exemplarily, when the first frequency domain resource and the second frequency domain resource are the same, the shared frequency domain resource includes the first frequency domain resource, and the shared frequency domain resource includes the second frequency domain resource.

[0115] As shown in FIG. 7A, when the first frequency domain resource and the second frequency domain resource are the same, the shared frequency domain resource is the first frequency domain resource or the second frequency domain resource.

[0116] For example, when the extended identifier indicates that the frequency domain resource indicated by the shared identifier is allocated to the first cell and the second cell, the first frequency domain resource and the second frequency domain resource are the same.

[0117] Exemplarily, when the first frequency domain resource and the second frequency domain resource are different, the shared frequency domain resource includes the intersection of the first frequency domain resource and the second frequency domain resource.

[0118] As shown in FIG. 7B, if the first frequency domain resource and the second frequency domain resource are different, the shared frequency domain resource is the intersection of the first frequency domain resource and the second frequency domain resource. Or it can be understood that the shared frequency domain resource includes the carrier included in the overlapping range of the first frequency domain resource and the second frequency domain resource.

[0119] For example, the intersection of the frequency domain resource indicated by the LTE dedicated identity and the frequency domain resource indicated by the NR dedicated identity is the shared frequency domain resource.

[0120] II. Channel power of the shared frequency domain resource

[0121] Exemplarily, if the first frequency domain resource and the second frequency domain resource are the same, and the first frequency domain resource is the total frequency domain resource of the first cell, and the second frequency domain resource is the total frequency domain resource of the second cell, the channel power of the shared frequency domain resource is equal to the maximum of the channel power of the total frequency domain resource of the first cell and the channel power of the total frequency domain resource of the second cell. In addition, the channel power of the shared frequency domain resource can also be greater than the maximum of the channel power of the total frequency domain resource of the first cell and the channel power of the total frequency domain resource of the second cell. For example, the channel power of the shared frequency domain resource is the sum of the above maximum and an offset.

[0122] For example, assume that the channel power of the shared frequency domain resource is denoted as PWR s , the channel power of the total frequency domain resource of the first cell is denoted as PWR1, and the channel power of the total frequency domain resource of the second cell is denoted as PWR2. In combination with the above FIG. 7A, PWR s ≥ max(PWR1, PWR2).

[0123] Wherein, the value of max(A, B) is the larger value (or the maximum value) of A and B.

[0124] Exemplarily, the channel power of the shared frequency domain resource can be determined according to one or more of the shared frequency domain resource, the total frequency domain resource of the first cell, the total frequency domain resource of the second cell, the power configuration of the first cell, or the power configuration of the second cell. The above method of determining the channel power of the shared frequency domain resource can be applicable to the case where the first frequency domain resource and the second frequency domain resource are the same, or the case where the first frequency domain resource and the second frequency domain resource are different.

[0125] In Example 1, the RRU can determine a ratio of the shared frequency domain resource to the total frequency domain resource of the first cell (denoted as a first ratio), and calculate a first power according to the channel power of the total frequency domain resource of the first cell and the first ratio. Similarly, the RRU can determine a ratio of the shared frequency domain resource to the total frequency domain resource of the second cell (denoted as a second ratio), and calculate a second power according to the channel power of the total frequency domain resource of the second cell and the second ratio. The channel power of the shared frequency domain resource is greater than or equal to the maximum of the first power and the second power, and less than the maximum of the channel power of the total frequency domain resource of the first cell and the channel power of the total frequency domain resource of the second cell.

[0126] For example, assume that the channel power of the total frequency domain resource of the first cell is denoted as PWR c1 , the channel power of the total frequency domain resource of the second cell is denoted as PWR c2 , the bandwidth of the total frequency domain resource of the first cell is X1, the bandwidth of the total frequency domain resource of the second cell is X2, and the bandwidth of the shared frequency domain resource is S0. Then the channel power of the shared frequency domain resource is greater than or equal to max(PWR c1 *S / X1, PWR c2 *S / X2).

[0127] Specifically, as shown in FIG. 7C, the starting frequency domain position of the first frequency domain resource is the same as that of the second frequency domain resource, and the ending frequency domain position of the first frequency domain resource is also the same as that of the second frequency domain resource. The shared frequency domain resource is the first frequency domain resource. The bandwidth S1 of the first frequency domain resource is 10M, the bandwidth S2 of the second frequency domain resource is 10M, i.e., S0=S1=S2=10M. Assume that PWR c1 =20W, PWR c2 =40W, and X1=X2=20M. Then the channel power of the shared frequency domain resource is greater than or equal to max(20*10 / 20, 40*10 / 20)W, i.e., the channel power of the shared frequency domain resource is greater than or equal to 20W.

[0128] In Example 2, the RRU can calculate a first power according to the channel power of the shared frequency domain resource and the unit bandwidth corresponding to the first cell. Similarly, the RRU can calculate a second power according to the channel power of the shared frequency domain resource and the unit bandwidth corresponding to the second cell. The channel power of the shared frequency domain resource is greater than or equal to the maximum of the first power and the second power, and less than the maximum of the channel power of the total frequency domain resource of the first cell and the channel power of the total frequency domain resource of the second cell.

[0129] For example, assume that the channel power of the unit bandwidth corresponding to the first cell is denoted as PWR b1 , and the channel power of the unit bandwidth corresponding to the second cell is denoted as PWR b2, the bandwidth of the shared frequency domain resource is S0, and the channel power of the shared frequency domain resource is ≥ max (PWR b1 * S, PWR b2 * S).

[0130] Specifically, as shown in FIG. 7C, the starting frequency domain position of the first frequency domain resource and the second frequency domain resource is the same, the ending frequency domain position is also the same, and the shared frequency domain resource is the first frequency domain resource. The bandwidth S1 of the first frequency domain resource is 10M, the bandwidth S2 of the second frequency domain resource is 10M, that is, S0=S1=S2=10M, and it is assumed that PWR b1 =1W, PWR b2 =2W, then the channel power of the shared frequency domain resource is max (1*10, 2*10), that is, the channel power of the shared frequency domain resource is ≥ 20W.

[0131] 620, the RRU transmits the channel power of the shared frequency domain resource.

[0132] Exemplarily, the RRU can further transmit third information, the third information indicating the channel power of the shared frequency domain resource. Optionally, the third information can further indicate the range of the shared frequency domain resource, for example, the third information further includes at least two of the starting frequency domain position of the shared frequency domain resource, the bandwidth of the shared frequency domain resource, and the ending frequency domain position of the shared frequency domain resource.

[0133] Exemplarily, in combination with the above-mentioned FIG. 5A, the RRU can transmit the channel power of the shared frequency domain resource to the first BBU and the second BBU respectively.

[0134] In combination with the above-mentioned FIG. 5B, the RRU can transmit the channel power of the shared frequency domain resource to the BBU.

[0135] In addition, the total frequency domain resource of the first cell further includes a private frequency domain resource of the first cell, and / or the total frequency domain resource of the second cell further includes a private frequency domain resource of the second cell.

[0136] In a possible implementation, the RRU can determine the private frequency domain resource of the first cell according to the total frequency domain resource of the first cell and the shared frequency domain resource, that is, the total frequency domain resource of the first cell includes the shared frequency domain resource and the private frequency domain resource of the first cell. Similarly, the RRU can determine the private frequency domain resource of the second cell according to the total frequency domain resource of the second cell and the shared frequency domain resource, that is, the total frequency domain resource of the second cell includes the shared frequency domain resource and the private frequency domain resource of the second cell. Wherein, the private frequency domain resource of the first cell can also be referred to as a third frequency domain resource. The private frequency domain resource of the second cell can also be referred to as a fourth frequency domain resource.

[0137] In another possible implementation, the total frequency domain resources of the first cell include first frequency domain resources and third frequency domain resources, and the first information further indicates the third frequency domain resources. The third frequency domain resources can be referred to as the private frequency domain resources of the first cell. And / or, the total frequency domain resources of the second cell include second frequency domain resources and fourth frequency domain resources, and the second information further indicates the fourth frequency domain resources. The fourth frequency domain resources can be referred to as the private frequency domain resources of the second cell.

[0138] The above method is generally applicable to scenarios where the first frequency domain resources and the second frequency domain resources are the same.

[0139] Regarding the two possible implementation methods mentioned above:

[0140] If a third frequency domain resource exists, the RRU can also determine the channel power of the third frequency domain resource. The channel power of the third frequency domain resource is determined based on one or more of the third frequency domain resource, the total frequency domain resource of the first cell, or the power configuration of the first cell. The RRU also transmits the channel power of the third frequency domain resource. For example, referring to Figure 5A above, the RRU can transmit the channel power of the third frequency domain resource to the first BBU. Referring to Figure 5B above, the RRU can transmit the channel power of the third frequency domain resource to the BBU. Similarly, if a fourth frequency domain resource exists, the RRU can also determine the channel power of the fourth frequency domain resource. The channel power of the fourth frequency domain resource is determined based on one or more of the range of the fourth frequency domain resource, the range of the total frequency domain resource of the first cell, or the power configuration of the first cell. The RRU also transmits the channel power of the fourth frequency domain resource. For example, referring to Figure 5B above, the RRU can transmit the channel power of the fourth frequency domain resource to the second BBU. Referring to Figure 5B above, the RRU can transmit the channel power of the fourth frequency domain resource to the BBU.

[0141] The specific calculation methods for the channel power of the third and fourth frequency domain resources can be found in Examples 1 and 2 above, and will not be repeated here. Furthermore, the channel power of the third frequency domain resource is less than the channel power of the total frequency domain resources of the first cell, and the channel power of the fourth frequency domain resource is less than the channel power of the total frequency domain resources of the second cell.

[0142] For example, as shown in Figure 7C, the first and second frequency domain resources have the same starting and ending frequency domain positions, and the shared frequency domain resource is the first frequency domain resource. The bandwidth S1 of the first frequency domain resource is 10 MHz, the bandwidth S2 of the second frequency domain resource is 10 MHz, that is, S0 = S1 = S2 = 10 MHz, the bandwidth S3 of the third frequency domain resource is 10 MHz, and the bandwidth S4 of the fourth frequency domain resource is 10 MHz.

[0143] Referring to Example 1 above, let's assume the channel power of the total frequency domain resources of the first cell is denoted as PWR. c1 PWR c1= 20W, the channel power of the total frequency domain resource of the second cell is recorded as PWR c2 , PWR c2 = 40W, the bandwidth X1 of the total frequency domain resource of the first cell is 20M, the bandwidth X2 of the total frequency domain resource of the second cell is 20M, then the channel power of the third frequency domain resource is ≥ PWR c1 * S3 / X1 = 20*10 / 20, that is, the channel power of the third frequency domain resource is ≥ 10W, the channel power of the fourth frequency domain resource is ≥ PWR c2 * S4 / X2 = 40*10 / 20, that is, the channel power of the fourth frequency domain resource is ≥ 20W.

[0144] In combination with the above example 2, assuming that the channel power of the unit bandwidth corresponding to the first cell is recorded as PWR b1 , PWR b1 = 1W, the channel power of the unit bandwidth corresponding to the second cell is recorded as PWR b2 , PWR b2 = 2W, then the channel power of the third frequency domain resource is ≥ PWR b1 * S3 = 1*10, that is, the channel power of the third frequency domain resource is ≥ 10W, the channel power of the fourth frequency domain resource is ≥ PWR b2 * S4 = 2*10, that is, the channel power of the fourth frequency domain resource is ≥ 20W.

[0145] In combination with the existing power allocation scheme, the total power required to be allocated by the RRU is PWR c1 + PWR c2 = 60W. However, by using the method provided in the present application, the total power required to be allocated by the RRU is the sum of the channel power of the shared frequency domain resource, the channel power of the third frequency domain resource and the channel power of the fourth frequency domain resource, that is, 20W+10W+20W=50W, and further, the above method can realize reasonable allocation of power and improve power utilization efficiency.

[0146] The embodiment shown in FIG. 6 is further described below in combination with FIG. 5A and FIG. 8:

[0147] S801: The first BBU sends first information to the RRU.

[0148] S802: The second BBU sends second information to the RRU.

[0149] Wherein, the present application does not limit the order of S801 and S802. The specific content of the first information and the second information can refer to the above 600.

[0150] S803: The RRU determines the channel power of the shared frequency domain resource according to the first information and the second information.

[0151] Exemplarily, the RRU can determine the shared frequency domain resource and the channel power of the shared frequency domain resource according to the first information and the second information.

[0152] For details, reference can be made to the above 610, which will not be repeated here.

[0153] In addition, the RRU can also determine the channel power of the third frequency domain resource and / or the channel power of the fourth frequency domain resource, which are not limited by the present application.

[0154] S804: The RRU sends the first power allocation information to the first BBU.

[0155] S805: The first BBU sends the first power allocation information to the coordination module (for example, the UMPT), wherein the first power allocation information includes the channel power of the shared frequency domain resource, or the channel power of the shared frequency domain resource and the channel power of the third frequency domain resource. Optionally, the first power allocation information further includes at least two of the starting frequency domain position of the shared frequency domain resource, the bandwidth of the shared frequency domain resource, and the ending frequency domain position of the shared frequency domain resource. The first power allocation information can also include at least two of the starting frequency domain position of the third frequency domain resource, the bandwidth of the third frequency domain resource, and the ending frequency domain position of the third frequency domain resource.

[0156] S806: The RRU sends the second power allocation information to the second BBU.

[0157] S807: The second BBU sends the second power allocation information to the coordination module, wherein the second power allocation information includes the channel power of the shared frequency domain resource, or the channel power of the shared frequency domain resource and the channel power of the fourth frequency domain resource. Optionally, the second power allocation information further includes at least two of the starting frequency domain position of the shared frequency domain resource, the bandwidth of the shared frequency domain resource, and the ending frequency domain position of the shared frequency domain resource. The second power allocation information can also include at least two of the starting frequency domain position of the fourth frequency domain resource, the bandwidth of the fourth frequency domain resource, and the ending frequency domain position of the fourth frequency domain resource.

[0158] Wherein, the present application does not limit the order of S804 and S806, and the order of S805 and S807.

[0159] Further, the coordination module can be realized to dynamically allocate frequency domain resources and channel power for the first cell and the second cell, and allocate corresponding proportion of channel power according to the proportion of the allocated frequency domain resources, as shown in FIG. 9.

[0160] For example, in combination with the above-mentioned related calculation content of FIG. 7C, the channel power of the shared frequency domain resource is 20W, the bandwidth of the shared frequency domain resource is 20W, 5M in the shared frequency domain resource is allocated to the first cell for use, and the corresponding channel power is 5W, and 15M in the shared frequency domain resource is allocated to the second cell for use, and the corresponding channel power is 15W.

[0161] It can be understood that, in combination with 5B, if the first cell and the second cell correspond to the same BBU, the RRU sends the power allocation information to the BBU, and the BBU sends the power allocation information to the coordination module, and the processing of the coordination module is similar, which will not be described here. The power allocation information can include one or more of the following: channel power of the shared frequency domain resource, channel power of the third frequency domain resource, and channel power of the fourth frequency domain resource. Optionally, the power allocation information further includes at least two of the following: the starting frequency domain position of the shared frequency domain resource, the bandwidth of the shared frequency domain resource, and the ending frequency domain position of the shared frequency domain resource.
