AI Technical Summary
Current mobile communication technologies do not effectively consider energy supply information in network selection, leading to inefficiencies in energy usage and increased carbon emissions.
The proposed solution involves transmitting energy supply information from network devices to wireless devices, allowing them to perform network selection based on green energy sources, energy ratios, consumption status, and carbon emissions, thereby prioritizing network nodes powered by local green energy.
This approach reduces total carbon emissions in communication systems by guiding user equipment (UE) to network nodes with lower energy transmission losses and higher green energy usage, enhancing network efficiency and sustainability.

[0015] Section headings are used in the present document only to improve readability and do not limit scope of the disclosed embodiments and techniques in each section to only that section. Furthermore, some embodiments are described with reference to Third Generation Partnership Project (3GPP) Fifth Generation (5G) New Radio (NR) or Sixth Generation (6G) standard for ease of understanding and the described technology may be implemented in different wireless system that implement protocols other than the NR or 6G protocol.
[0016] 0. Initial discussion
[0017] In order to cut down carbon emissions and enhance network efficiency, more and more operators seek to use green energy sources (e.g., solar energy, wind power, geothermal energy, biomass and hydroelectric power) for their network. Due to the highly variable and unpredictable nature of green energy sources, different network nodes may be powered with different type of energy. For example, some network nodes may be powered by non-green energy while other network nodes may be powered by green energy. Some network nodes may also be powered by a mixture of non-green energy and green energy. In this case, the ratio of green energy of network node is determined as the ratio of the power that is used from green energy sources as a percentage of total power usage in a given time unit. Calculation of ratio of green energy is done by means of averaging or applying a statistical model.
[0018] Moreover, for the green energy used by network node, it can be generated at the site locally or delivered from the grid far away. For example, in an on-site situation, a wind power generation equipment may be installed together with a network node at a same location, so the network node which can use the local green energy conveniently, without having to cause burden to power transmission grid. For the network node which use the green energy delivered from the grid, from far away, the energy transmission loss should be taken into account. From the perspective of carbon emission reduction, the network node powered by local on-site green energy should be prioritized over the network node powered by green energy produced farther away.
[0019] In some embodiments disclosed in the present document, a telecom operator provides communication service to subscribers considering the green energy supply sources of network node. Here, the energy sources information denotes energy type (e.g., green energy, non-green energy, or the ratio of green energy) and energy location (e.g., energy at the site or delivered from grid) . Based on the energy sources information, the operator can select the network nodes powered by local on-site green energy in the connection path to serve subscribers as much as possible.
[0020] In present day wireless systems, the network selection is mainly based on the radio quality and the subscription of users without considering the energy supply information at network side.
[0021] For example, presently, from UE’s perspective, the cell selection and reselection is based on the radio quality. UE typically performs cell selection when the radio quality is above certain threshold and perform measurements on neighbor cell to find the highest ranked cell to re-select to.
[0022] From a network’s perspective, the radio access network (RAN) node will select core network (CN) node based on the subscription of users, e.g., the registration, the allowed Single-Network Slice Selection Assistance Information (S-NSSAI) , the registered NPN (non-public network) .
[0023] Using the techniques disclosed in the present document, network energy supply information will be exposed to user devices and among network nodes to assist network selection so that a UE can be guided to network nodes supplied by green energy or with less energy transmission loss and then reduce the total carbon emission in the communication system.
[0024] 1. Examples of embodiments
[0025] In some embodiments, a UE receives the energy supply information from the network side and performs network selection base on the received network energy supply information. For example, a UE may implement method 210 depicted in FIG. 2A. At 212, UE receive energy supply information from the network (e.g., a network device) . At 214, UE performs an energy operation. For example, a network resource selection may be performed using the energy supply information.
[0026] FIG. 2B depicts an example method 220 that may be implemented by the network side, e.g., a network device. The method 200 includes, transmitting (222) , by a network device to a wireless device, energy supply information. Various embodiments disclosed herein provide additional features of “energy supply information” and various energy operations that may be performed by the UE. Furthermore, various possible network resources that may be selected using the energy supply information are also disclosed in the present document.
[0027] 1.1 Examples of energy supply information
[0028] In various embodiments, energy supply information may include one or more of the following:
[0029] The energy supply information of a cell / carrier / network node or a list of cells / carriers / network nodes
[0030] ■ A cell / carrier / network node powered by green energy (e.g., solar energy, wind power, geothermal energy, biomass and hydroelectric power) will be assigned with a green code. And the green code for cell / carrier / network node will be provided to UE to assist network selection.
[0031] ■ The ratio of green energy in supply for a cell / carrier / network node or the average ratio of green energy in supply for a list of cells / carriers / network nodes.
[0032] ■ Ratio of green energy in supply for a cell / carrier / network node = The green energy consumption for a given time / The total energy consumption for the same time period.
[0033] ■ The ratio of locally produced green energy supply for a cell / carrier / network node or the average ratio of locally produced green energy for a list of cells / carriers / network nodes.
[0034] ■ Ratio of locally produced green energy, which is generated by green power generation devices within certain distance, in supply for a cell / carrier / network node = The locally produced green energy consumption for a given time / The total energy consumption for the same time period.
[0035] ■ The energy consumption status of a cell / carrier / network node or a list of cells / carriers / network nodes. For example, some thresholds on the power consumption have been set inside a cell / carrier / network node, the energy consumption status “green” means the energy consumption is lower than a first threshold. “yellow” means the energy consumption is higher than a first threshold and lower than a second threshold. “Red” means the energy consumption is higher than a second threshold.
[0036] ■ The carbon emission of a cell / carrier / network node or a list of cells / carriers / network nodes over a certain time period. Here, Carbon emission may be measured as the quantity of emitted equivalent carbon dioxide (e.g., kg of CO2) .
[0037] FIG. 1A shows an example wireless network that includes three networks or cells, network 1, 2 and 3. In this example, network 1 is powered by locally produced green energy (e.g., wind energy) , network 2 is powered by clean energy of some kind (e.g., solar) that is transmitted to the network equipment of network 2 from another location, while network 3 is powered by conventional energy sources such as power from a power grid in the region where the network is operating. In one example embodiment, due to the energy code of network 1 being green, the wireless device may select network 1 over networks 2 and 3.
[0038] FIG. 1B shows another example of a wireless network in which various energy consumption statuses are highlighted. In the left-most network, energy consumption status may have some value such as yellow value, indicating that there is still room for the network to consume more power. The middle network and the rightmost network may have energy consumption codes red, indicating that the energy consumption status has reached an upper bound. As depicted, in this case the wireless device may connect with the network with yellow status.
[0039] 1.2 Examples of transmission of energy supply information by a network device
[0040] In some embodiments, the network may broadcast the energy supply information to all the UEs covered, for example, via system information.
[0041] Alternatively, or in addition, the network provides the energy supply information to UE in a dedicated manner, for example to a certain UE under coverage or some of the UEs under coverage.
[0042] In some embodiments, such information can be provided in an on-demand way, e.g., network only provides after UE request such information.
[0043] ■ UE can send such request via uplink wake up signal, random access procedure, a MAC control element, or a dedicated radio resource control message.
[0044] ■ UE can send such request via main radio or low power radio.
[0045] ◆ Main radio refers to the Tx / Rx module operating for NR signals / channels apart from signals / channel related to low-power wake-up.
[0046] ◆ Low power radio refers to the Tx / Rx module operating for receiving / processing signals / channel related to low-power wake-up.
[0047] 1.3 Examples of UE behavior upon reception of the configuration
[0048] UE can be in a green mode or a normal mode. The normal mode may be, for example, legacy mode in which UE operates in a manner compatible with an earlier wireless protocol such as the existing version of 3G, 4G LTE or 5g NR. In various embodiments, the network selection considering energy supply information can apply to all kinds of UEs or only UEs in the green mode.
[0049] 1.3.1 Examples of communication operations upon receiving green code
[0050] According to various embodiments, upon receiving the green code of cells / carriers / network nodes:
[0051] ■ UE only select cells / carriers / network nodes with green code.
[0052] ■ Cells / carriers / network nodes with green code will be treated with higher priority, e.g., to be treated as the highest priority or with a common priority offset added to the cell / carrier / network node selection priority. The priority and common priority offset can be per cell or per carrier or per frequency.
[0053] ■ Cells with green code can be assigned with an offset added to the measured RSRP (reference signal received power) and / or RSRQ (reference signal received quality) and thus be prioritized in the ranking of the cell radio quality based on RSRP and / or RSRQ,
[0054] Rs = Qmeas, s+Qhyst -Qoffsettemp + Qoffsetgreen
[0055] Rn = Qmeas, n -Qoffset -Qoffsettemp + Qoffsetgreen
[0056] ■ UE select cells / carriers / network nodes for which the measured radio quality, e.g., RSRP and / or RSRQ, is above certain thresholds, and is assigned with green code.
[0057] ■ UE ranks cells / carriers / network nodes with green code based on the radio quality, e.g., RSRP and / or RSRQ, and select the highest ranked cell / carrier / network node.
[0058] ■ UE ranks cells / carriers / network nodes based on the radio quality, e.g., RSRP and / or RSRQ, and check from the highest ranked ones until it finds one with green code. For example, the ranking among four cells: Cell1>Cell2>Cell3>Cell4, while only cell2 and cell3 is assigned with green code. UE would select Cell2.
[0059] 1.3.2 Examples of communication operations upon receiving a ratio of green energy supply

[0061] ■ A threshold of the ratio is also defined or configured. UE only select cells / carriers / network nodes with the ratio larger than or equal to this threshold.
[0062] ■ A threshold of the ratio is also defined or configured. Cells / carriers / network nodes with green energy supply ratio larger than or equal to the threshold will be treated with higher priority, e.g., to be treated as the highest priority or with a common priority offset added to the cell / carrier / network node selection priority. The priority and common priority offset can be per cell or per carrier or per frequency.
[0063] ■ A threshold of the ratio is also defined or configured. Cells with green energy supply ratio larger than or equal to this threshold can be assigned with an offset added to the measured RSRP and / or RSRQ and thus be prioritized in the ranking of the cell radio quality based on RSRP and / or RSRQ,
[0064] Rs = Qmeas, s+Qhyst -Qoffsettemp + Qoffsetgreen
[0065] Rn = Qmeas, n -Qoffset -Qoffsettemp + Qoffsetgreen
[0066] ■ A threshold of the ratio is also defined or configured. UE select cells / carriers / network nodes with the ratio larger than or equal to this threshold and for which the measured radio quality, e.g., RSRP and / or RSRQ, is above certain thresholds.
[0067] ■ A threshold of the ratio is also defined or configured. UE ranks cells / carriers / network nodes whose green energy supply ratio is larger than or equal to this threshold based on the radio quality, e.g., RSRP and / or RSRQ, and select the highest ranked cell / carrier / network node.

UE ranks cells / carriers / network nodes based on the radio quality, e.g., RSRP and / or RSRQ, and check from the highest ranked ones until it finds one whose green energy supply is above this threshold. For example, the ranking among four cells: Cell1>Cell2>Cell3>Cell4, while the green energy supply ratio for each cell is as follows. The green energy supply ratio threshold is 0.5, thus cell2 will be selected.
[0069] ■ UE ranks cells / carriers / network nodes based on the radio quality, e.g., RSRP and / or RSRQ, and select several cells / carriers / network nodes as the candidates. UE would select the cell / carrier / network node with the highest green energy supply ratio among the candidate cells.
[0070] ◆ The candidates can be selected based on RSRP and / or RSRP range, e.g., range to best cell. For example, the range to best cell is 4 while the best cell, e.g., highest ranked cell’s RSRP is 10. The cells whose RSRP is larger than 10-4=6 would be treated as the candidate cells.
[0071] ◆ The maximum number N of candidate cells is configured or defined. And the highest ranked N cells will be treated as candidates.
[0072] UE select the cell / carrier / network node with the highest green energy supply ratio among the cells / carriers / network nodes whose radio quality, e.g., RSRP and / or RSRQ, is above certain thresholds.

[0112] ■ An upper limit of the carbon emission is also defined or configured. UE select cells / carriers / network nodes with the carbon emission less than or equal to this upper limit and for which the measured radio quality, e.g., RSRP and / or RSRQ, is above certain thresholds.
[0113] ■ An upper limit of the carbon emission is also defined or configured. UE ranks cells / carriers / network nodes whose carbon emission is less than or equal to this upper limit based on the radio quality, e.g., RSRP and / or RSRQ, and select the highest ranked cell / carrier / network node.

[0119] Implementation examples 1 to 8 are described in the following sections to highlight certain features of the disclosed technical solutions, along with accompanying FIGS. 3 to 10. In the figures, the steps of these implementation examples are references with corresponding step number. Depiction of steps, where repetitive or unnecessary for understanding of the technical solution, have been omitted for clarity. It is noted that the network entities in FIGS. 3 to 10 may be a base station or another network function that is specifically designed to allow use of energy information. Furthermore, in the below examples, although certain techniques have been disclosed as “alternatives, ” this does not mean that these techniques are mutually exclusive. In other words, these techniques are enumerated as alternatives only for brevity of description, but many other embodiments in which some, or all, of these alternatives are combined into a same implementation, are possible. Furthermore, although the various steps performed by the implementation examples have been described as beginning when traffic in the UE is not busy, such a condition is one example only. The steps may be initiated in other situations also, e.g., upon UE receiving an input from a user (e.g., application layer input) , or the UE receiving a command from the network, or the UE being at a fully charged or at a power state that is above a threshold, and so on.
[0120] 2. Implementation example 1:
[0121] FIG. 3 depicts an example of operational flow of network resource selection performed by a UE according to example 1.
[0122] Step 10a: The traffic in UE is not busy and UE move to Green mode. This step can also be omitted, which means all the UE can obtain and apply the network energy supply information in network selection.
[0123] Step 10b: UE request the network energy supply information. This step can also be omitted, which means network would provide network energy supply information without waiting for request from UE.
[0124] UE can send such request via uplink wake up signal, random access procedure, a MAC control element, or a dedicated radio resource control message.
[0125] UE can send such request via main radio or low power radio. Main radio refers to the Tx / Rx module operating for NR signals / channels apart from signals / channel related to low-power wake-up. Low power radio refers to the Tx / Rx module operating for receiving / processing signals / channel related to low-power wake-up.
[0126] Step 11: Network provide the Green code of the serving and neighbor cells / carriers / network nodes.
[0127] --Alternative 1: The network broadcasts the energy supply information to all the UEs covered, for example, via system information.
[0128] --Alternative 2: The network provides the energy supply information to UE in a dedicated manner, for example to a certain UE under coverage or some of the UEs under coverage.
[0129] Step 12: UE finds that the serving cell / carrier / network is not assigned with Green code and starts to look for another cell / carrier / network with Green code.
[0130] --Alternative 1: UE ranks the candidate or neighbor cells / carriers / networks with Green code based on the measured RSRP / RSRQ and select the highest ranked one.
[0131] --Alternative 2: Cells / carriers / network nodes with green code will be treated with higher priority, e.g., to be treated as the highest priority or with a common priority offset added to the cell / carrier / network node selection priority, UE selects cell / carrier / network following the priority, e.g., check from highest priority to lower priority ones. For cell / carrier / network with the same priority, UE would select based on the radio quality, e.g., RSRP / RSRQ, and select the highest ranked one with the highest RSRP / RSRQ. The common priority offset can be configured by network or defined as fixed value in specifications. The priority and common priority offset can be per cell or per carrier or per frequency.
[0132] --Alternative 3: UE ranks cells / carriers / network nodes based on the radio quality, e.g., RSRP and / or RSRQ, and check from the highest ranked ones until it finds one with green code. For example, the ranking among four cells: Cell1>Cell2>Cell3>Cell4, while only cell2 and cell3 is assigned with green code. UE would select Cell2.
[0133] --Alternative 4: UE selects cells / carriers / network nodes for which the measured radio quality, e.g., RSRP and / or RSRQ, is above certain thresholds, and is assigned with green code. The RSRP and / or RSRQ threshold can be configured by network or defined as fixed value in specifications. If there are more than one cells / carriers / networks with Green code and above the RSRP and / or RSRQ threshold, UE can select via implementation or follow the cell / carrier / network priority configured by network or select the cell / carrier / network with the highest radio quality, e.g., RSRP / RSRQ / SINR (signal to interference and noise ratio) .
[0134] 3. Implementation example 2:
[0135] FIG. 4 depicts an example of operational flow of network resource selection performed by a UE according to example 2.
[0136] Step 20a: The traffic in UE is not busy and UE move to Green mode. This step can also be omitted, which means all the UE can obtain and apply the network energy supply information in network selection.
[0137] Step 20b: UE requests the network energy supply information. This step can also be omitted, which means network would provide network energy supply information without waiting for request from UE.
[0138] UE can send such a request via uplink wake up signal, random access procedure, a MAC control element, or a dedicated radio resource control message.
[0139] UE can send such a request via main radio or low power radio. Main radio refers to the Tx / Rx module operating for NR signals / channels apart from signals / channel related to low-power wake-up. Low power radio refers to the Tx / Rx module operating for receiving / processing signals / channel related to low-power wake-up.
[0140] Step 21: The network provides the ratio of the green energy supply for
[0141] cells / carriers / network modes to UE.
[0142] --Alternative 1: The network broadcasts the energy supply information to all the UEs covered, for example, via system information.
[0143] --Alternative 2: The network provides the energy supply information to UE in a dedicated manner, for example to a certain UE under coverage or some of the UEs under coverage.

[0300] The disclosed and other embodiments, modules and the functional operations described in this document can be implemented in digital electronic circuitry, or in computer software, firmware, or hardware, including the structures disclosed in this document and their structural equivalents, or in combinations of one or more of them. The disclosed and other embodiments can be implemented as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a computer readable medium for execution by, or to control the operation of, data processing apparatus. The computer readable medium can be a machine-readable storage device, a machine-readable storage substrate, a memory device, a composition of matter effecting a machine-readable propagated signal, or a combination of one or more of them. The term “data processing apparatus” encompasses all apparatus, devices, and machines for processing data, including by way of example a programmable processor, a computer, or multiple processors or computers. The apparatus can include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, or a combination of one or more of them. A propagated signal is an artificially generated signal, e.g., a machine-generated electrical, optical, or electromagnetic signal, that is generated to encode information for transmission to suitable receiver apparatus.
[0301] A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document) , in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code) . A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.
[0302] The processes and logic flows described in this document can be performed by one or more programmable processors executing one or more computer programs to perform functions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit) . Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read only memory or a random-access memory or both. The essential elements of a computer are a processor for performing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto optical disks, or optical disks. However, a computer need not have such devices. Computer readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto optical disks; and CD ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.
[0303] It is noted that operation of the wireless communications as disclosed herein causes a reduction in greenhouse gas emissions compared to traditional methods. The International Energy Agency (IEA) estimates that the overall share of carbon emissions from information and communication technologies (ICT) accounts for approximately 4%of the total amount of CO2 emitted around world. Further, conventional networks can sometimes exacerbate the causes of climate change. For example, at an average of approximately 485g of CO2 per KWh of electricity that is produced worldwide, it results in a rough estimate of 145.5 million metric tons of CO2. The implementations disclosed herein for operating the wireless communications can reduce power consumption by improving efficiency of channel state reporting and reducing signaling overhead and latency.
[0304] Moreover, Global System for Mobile Communications Association (GSMA) , the organization that represents mobile operators and the telecommunication industry worldwide, has estimated that currently 20–40%of the operating cost of network operators is taken up by electricity, and that 5G can cause a substantial (as much as four to five fold) increase of energy consumption in the RAN, but that the technical means to reduce this consumption can be included in later generation mobile networks, such as 6G networks. Avoiding unnecessary resources for handovers that may not be successful or optimal, by using the pre-verification techniques described herein, may cause less wireless message transmissions. Therefore, the disclosed implementations for operation of the wireless communications mitigates climate change and the effects of climate change.
