Furthermore, the network entity mentioned in this disclosure can refer to at least one of: the first entity, the second entity, or the third entity.
[0032] Embodiment 1: Definition of energy level of network entity
[0033] Aspect 1: How to define the energy level of network entity
[0034] The energy level of a network entity can represent the energy performance of a network entity and the energy performance of a network entity can refer to at least one of the energy / power consumption of a network entity, the energy efficiency of a network entity, the ratio between the energy consumption value of a network entity and a reference value, whether the network entity operates in an energy saving state, the specific configurations of the network entity, or the ratio of physical resource block (PRB) (i.e., the percentage of PRB occupation, the occupied percentage of the PRB resources, the PRB duty cycle ratio) .
[0035] In some embodiments, the energy consumption of a network entity may include the renewable energy. In some implementations, the energy efficiency of the network entity represents the effective output provided per unit energy consumption. In some embodiments, the output can be the data volume. In some embodiments, the reference value can be the energy consumption of a network entity obtained / calculated under a specific configuration. In some embodiments, the different energy level means that the network entity operates under the different configuration information. In some embodiments, the ratio of PRB represents the ratio between the used PRB number and the available PRB number. In some embodiments, the used PRB number refers to the used PRB number for network entity. In some embodiments, the available PRB number refers to the total PRB number in the network / cell / system, or the total available PRB number for the network entity.
[0036] In some embodiments, the energy level of the network entity can be obtained / calculated using configuration information. The configuration information includes at least one of : a specific time information / time duration / time slot , the configured / used frequency resource information, the used antenna ports number, the specific antenna number, the specific activated elements number, the specific activated / used panels number, the specific activated / used radio frequency units number, the specific activated forwarding units number, the specific energy source, the ratio / percentage of different energy sources, the carbon intensity or carbon dioxide (CO2) emission intensity, or the carbon dioxide emission quantity. The time information can refer to at least one of: a duty cycle, a duration, the one or more symbols, the one or more slots, a period. In some implementations, the specific time information for the different network entities can be same or different. the frequency resource information includes at least one of : an RB number, an RE number. In some embodiments, the energy source can refer to the energy supply, power supply, and may have different sources / supplies, including the first energy source, the second energy source, the third energy source and etc. In some examples, the first energy source can represent that the energy is generated / come from the power grid, and the second energy source represent that the energy come from the renewable energy / clean energy. In some examples, the first energy source can represent the energy resource is the wind energy, and the second energy source represent the energy source is the solar energy. In some embodiments, the ratio / percentage of different energy sources can refer to the ratio of first energy source, the ratio of the second energy source or the ratio of the third energy source. In some embodiments, the ratio / percentage of different energy sources can represent the used time duration for the corresponding energy sources over the total time duration. For example, among one day (i.e., 24 hours) , there are 6 hours that the energy is provided by the renewable energy, and for the remaining time, the energy is provided by the power grid, then the ratio of renewable energy is 25%. In some embodiments, the ratio / percentage of different energy sources can represent the energy consumption of corresponding energy source over the whole / total energy consumption. In some embodiments, the carbon intensity / the carbon dioxide emission intensity is used to represent the quantity of CO2 equivalent emission per unit of total energy consumption. In some embodiments, the carbon intensity represents the quantity of CO2 equivalent emission per unit of total energy consumption for a period of time. In some embodiment, the carbon dioxide emission quantity is used to represent the quantity for of CO2 equivalent emission for the whole energy consumption.
[0037] In some embodiments, the renewable energy can refer to the clean energy. Clean energy can represent the energy from renewable / natural sources such as, wind, solar, aerothermal, geothermal, hydrothermal, hydropower, biomass, landfill gas, sewage treatment plant gas, biogases, among others.
[0038] Aspect 2: The format of energy level
[0039] Regarding the format of energy level of the network entity, the format can take the form of at least one of a value, an index, or a state. Each energy level of network entity may include one or more values. For example, the energy level of the network entity represents the energy consumption may include two values that used to represent a value range. Thus, the energy consumption of network entity is within the value range. Different indexes can represent the different energy level of the network entity.
[0040] In some embodiments, one or more threshold values can define the different energy level of the network entity. The one or more threshold values can compare with the energy performance of the network entity, to determine different energy levels. In some embodiments, the indexes with a lower value represents that the better energy performance, and the indexes with higher value represents the worse energy performance. In some embodiments, the indexes with higher value represents that the better energy performance, and the indexes with lower value represents the worse energy performance.
[0041] Example 01: In some embodiments, when the energy performance refers to the energy consumption (E1) of the network entity, the three threshold values can compare with the energy consumption value of the network entity, and the energy level can be determined based on the following table. The energy level 0 represents that the network entity includes a better energy performance with a lower energy consumption.
[0042] Example 02: In some embodiments, when the energy performance refers to whether the network entity operates in an energy saving state, (e.g., 0, 1, ) can be used. The energy level 0 represents that the network entity operates in a non-energy-saving state, while the energy level 1 represents that the network entity operates in an energy-saving state.
[0043] The different states can represent the different energy level of a network entity. In some embodiments, the energy level of the network entity can include at least one of a high state, a medium state, or a low state. Each state can indicate the different state of energy performance of the network entity. In some embodiments, the energy level of a network entity can include at least one of an energy-saving state or a non-energy saving state. The energy saving state indicates that part of functions / configurations of the network entity can be powered-down / off / not used / not activated. The non-energy saving state indicates that there are no operations of network entity for energy saving purpose. In some embodiments, the one or more threshold values can define the different energy level of the network entity. The one or more threshold values can compare with the energy performance of a network entity to determine different energy levels.
[0044] Example 03: In some embodiments, when the energy performance refers to the energy consumption (E3) of a network entity, the energy level can include at least one of a high state, a medium state, or a low state. The high state represents that the energy consumption is in a high level, the medium state represents that energy consumption is a medium level, and the low state presents the energy consumption is in a low level.
[0045] In some embodiments, the one or more threshold values can be at least one of a pre-defined for the network entity, indicated by the first entity / second entity, up to network entities'respective capability and performance. In some embodiments, the one or more threshold values for the different network entities can be different or same. In some embodiments, the one or more threshold values can be the same for the same type of network entities. In a similar manner, the one or more threshold values for the different types of network entities can be different.
[0046] In some embodiments, the energy level definition is same for the one or more network entities. In some embodiments, the energy level definition is different for the one or more network entities.
[0047] Aspect 3:
[0048] In some embodiments, using the first configuration information received from the first entity or the second entity, allows for a calculation of the energy level of network entity. The first configuration information includes at least one of the one or more threshold values provided by the first entity or second entity, the one or more configuration information. In some embodiments, the network entity uses the one or more threshold values to calculate the energy level. In some embodiments, the configuration information can refer to the configuration information described above.
[0049] Example 01: The second entity (e.g., BS 102) can indicate that the first configuration information includes the one or more threshold values and the time duration information for the third entity. The third entity can use the first configuration information calculate or obtain the energy level. The third entity can calculate the energy consumption consumed in the time duration and compare the energy consumption value with the provided one or more threshold values, then obtain the corresponding energy level.
[0050] Embodiment 2: The interaction and reporting of energy related information between the different types of entity
[0051] Aspect 1: the interaction direction between different entities
[0052] One or more cases are considered for the interaction between different entities. In a first case, one or more of the first type of information can be reported from the second entity to the first entity. In some embodiments, before the report of the one or more of the first type of information, the first entity can transmit one or more of a second type of information to the second entity. In some embodiments, after receiving the first type of information, the first entity can indicate one or more of a third type of information to the second entity. In some embodiments, one or more of the third type of information can be indicated with the one or more of the second type of information. In a second case, the third entity can report one or more of the first type of information to the first entity or the second entity. In some embodiments, before the report of one or more of the first type of information, the first entity or the second entity can transmit the one or more of the second type of information to the third entity. In some embodiments, after receiving the one or more of the first type of information, the first entity / second entity can indicate the one or more of the third type of information to the first entity.

In common signaling, the information transmitted can be applicable for all third entities. In multicast signaling, the information transmitted can be applicable for the one or more third entities. In unicast signaling, the information transmitted can be applicable for the one third entity. In some embodiments, the signaling mentioned above can be at least one of: RRC, MAC CE, DCI signaling.
[0064] In some embodiments, the specific energy level can be used to represent that corresponding network entity (e.g., the first entity, second entity or third entity) is operating / entered on the specific energy state, e.g., the energy-saving / power-saving state, or the non-energy-saving / non-power-saving state. And in some implementations, the different energy level can represent the different energy state / status. In some embodiments, the indicated energy level can be used to indicate that the corresponding entity should enter into the corresponding energy state, e.g., energy-saving / power-saving state, or non-energy-saving / non-power-saving state. For example, the Base station (e.g., the second entity) indicates energy level 0 to the NCR (e.g., third entity) , and energy level 0 can also mean that the NCR shall operate in energy-saving state.
[0065] Example 01: The second entity can be the BS 102 and the third entity may include the RIS, NCR and other network entities. In this manner, the third entities can report the energy level information to the BS 102. In this manner, the one or more of the first type of information may include the energy level and the corresponding threshold values determine the energy level of each network entity. Accordingly, the BS 102 can choose the suitable third entity for scheduling and operating to satisfy the energy consumption requirement. For example, the BS 102 can include the on / off information in the one or more of the third type of information to turn on or turn off some third entities to save the energy.
[0066] Example 02: The first entity can be the CN, the second entity can be the BS 102, and the third entity may include the different types of network devices (e.g., the RIS, NCR, etc. ) . In this manner, the one or more of the first type of information can include the total energy consumption among the network 100 such that from the BS can report the one or more of the first type of information to the CN. Then the CN may determine that the energy consumption has exceeded the maximum energy consumption limit, thus the CN can indicate to the BS 102, via the one or more of the third type of information, that the BS 102 can operate in an energy saving state or that the BS 102 can lower the energy consumption. Thus, the BS 102 can execute some operations for the energy saving purpose.
[0067] Embodiment 3: the additional control information for the network entity
[0068] In order to control the operation of network entity (e.g., the RIS) , the controller can transmit the control information. The controller can include the BS 102 or the UE.
[0069] Aspect 1: The characteristics of network entity shall be known by the controller
[0070] In order to better transmit the control information to the network entity, the characteristics of network entity maybe known by the controller. The characteristic information may include at least one of control information, the number of elements, element spacing, and the supported operating mode. In some embodiments, the number of elements represents the total number of elements for the network entity. In some embodiments, the network entity (e.g., RIS) may be a surface, thus the number of elements can include two values, where the first value indicates the number of elements in row, and the second value indicates the number of elements in column. The elements spacing refers to the distance between the two adjacent elements of network entity. In some embodiments, if the elements spacing for the row and column is different, the element spacing may include two values, where the first value indicates the element spacing for the two elements in row, and the second value indicates the element spacing for the two elements in column. The supported operating mode of network entity may include: a reflection mode, a refraction mode, a transmission mode, an absorption mode, a receiving mode, and a backscattering mode. The network entity or the OAM can report the above mentioned one or more characteristics to the controller.
[0071] Aspect 2: the control information transmitted from the controller to the network entity
[0072] After knowing the characteristics of network entity, the controller can transmit the control information to the network entity. The control information may include a value that indicates the actual element spacing and the indicated one or more operating mode that the network entity should operate. In some embodiments, the value is an integer value or a positive integer value (e.g., referring to a1) . The value can indicate the multiples for the element spacing of two adjacent elements (e.g., referring to s) , indicating that the actual activated or used element spacing of two adjacent actual activated or used elements should be the s*a1. The value can indicate that the number of elements between two adjacent activated / used elements is a1.
[0073] Example 01: Taking the RIS as an example of network entity. The value is a1=2, indicating the actual activated or used element spacing of two adjacent actual used or activated elements should be in the 2s. FIG. 3 illustrates an example 300 of activated elements of RIS.
[0074] Example 02: Taking the RIS as an example of network entity. The value is a1=2, indicating that the number of elements between two adjacent activated or used elements is 2. In this manner, the activated or used elements of the network entity can be shown in FIG. 4. In this manner, the actual used element spacing between the two adjacent used or activated elements is 3s.
[0075] In some embodiments, there may exist the case that the actual used elements spacing between the two adjacent used or activated elements for the row and column are different. In this manner, the indicated value includes two values. The first value can be applicable for the row, while the second value can be applicable for the column. In some embodiments, the control information can be indicated from the controller to the network entity via at least one of RRC signaling, MAC CE signaling, DCI signaling, UCI signaling, and side control information (SCI) signaling.

The method 500 may be executed by any one or more of the components and devices detailed herein in conjunction with FIGs. 1–4. In overview, the method 500 may be performed by a wireless communication node (e.g., a base station (BS) 102) , in some embodiments. Additional, fewer, or different operations may be performed in the method 500 depending on the embodiment. At least one aspect of the operations is directed to a system, method, apparatus, or a computer-readable medium.
