3GPP NETWORKING WITH CONSIDERATION OF ENERGY RELATED INFORMATION
[0001] CROSS-REFERENCE TO RELATED APPLICATION (S)
[0002] This application claims the benefits of U.S. Provisional Application Serial No. 63 / 594, 975, entitled “3GPP networking considering energy related information” and filed on November 1, 2023, which is expressly incorporated by reference herein in its entirety.TECHNICAL FIELD
[0003] The present disclosure relates generally to wireless communications, and more particularly, to techniques of 3GPP networking with consideration of energy related information.BACKGROUND
[0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
[0005] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.
[0006] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR) . 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT) ) , and other requirements. Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.SUMMARY
[0007] The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects.

[0019] The detailed description set forth below in connection with the appended drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring such concepts.
[0020] Several aspects of telecommunications systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements” ) . These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0021] By way of example, an element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs) , central processing units (CPUs) , application processors, digital signal processors (DSPs) , reduced instruction set computing (RISC) processors, systems on a chip (SoC) , baseband processors, field programmable gate arrays (FPGAs) , programmable logic devices (PLDs) , state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.
[0022] Accordingly, in one or more example aspects, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can comprise a random-access memory (RAM) , a read-only memory (ROM) , an electrically erasable programmable ROM (EEPROM) , optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer.
[0023] FIG. 1 is a diagram illustrating an example of a wireless communications system and an access network 100. The wireless communications system (also referred to as a wireless wide area network (WWAN) ) includes base stations 102, UEs 104, an Evolved Packet Core (EPC) 160, and another core network 190 (e.g., a 5G Core (5GC) ) . The base stations 102 may include macrocells (high power cellular base station) and / or small cells (low power cellular base station) . The macrocells include base stations. The small cells include femtocells, picocells, and microcells.
[0024] The base stations 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) ) may interface with the EPC 160 through backhaul links 132 (e.g., SI interface) . The base stations 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN) ) may interface with core network 190 through backhaul links 184. In addition to other functions, the base stations 102 may perform one or more of the following functions: transfer of user data, radio channel ciphering and deciphering, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity) , inter cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS) , subscriber and equipment trace, RAN information management (RIM) , paging, positioning, and delivery of warning messages. The base stations 102 may communicate directly or indirectly (e.g., through the EPC 160 or core network 190) with each other over backhaul links 134 (e.g., X2 interface) . The backhaul links 134 may be wired or wireless.
[0025] The base stations 102 may wirelessly communicate with the UEs 104. Each of the base stations 102 may provide communication coverage for a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, the small cell 102’ may have a coverage area 110’ that overlaps the coverage area 110 of one or more macro base stations 102. A network that includes both small cell and macrocells may be known as a heterogeneous network. A heterogeneous network may also include Home Evolved Node Bs (eNBs) (HeNBs) , which may provide service to a restricted group known as a closed subscriber group (CSG) . The communication links 120 between the base stations 102 and the UEs 104 may include uplink (UL) (also referred to as reverse link) transmissions from a UE 104 to a base station 102 and / or downlink (DL) (also referred to as forward link) transmissions from a base station 102 to a UE 104. The communication links 120 may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication links may be through one or more carriers. The base stations 102 / UEs 104 may use spectrum up to 7 MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL) . The component carriers may include a primary component carrier and one or more secondary component carriers. A primary component carrier may be referred to as a primary cell (PCell) and a secondary component carrier may be referred to as a secondary cell (SCell) .
[0026] Certain UEs 104 may communicate with each other using device-to-device (D2D) communication link 158. The D2D communication link 158 may use the DL / UL WWAN spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH) , a physical sidelink discovery channel (PSDCH) , a physical sidelink shared channel (PSSCH) , and a physical sidelink control channel (PSCCH) . D2D communication may be through a variety of wireless D2D communications systems, such as for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.
[0027] The wireless communications system may further include a Wi-Fi access point (AP) 150 in communication with Wi-Fi stations (STAs) 152 via communication links 154 in a 5 GHz unlicensed frequency spectrum. When communicating in an unlicensed frequency spectrum, the STAs 152 / AP 150 may perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available.
[0028] The small cell 102’ may operate in a licensed and / or an unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell 102’ may employ NR and use the same 5 GHz unlicensed frequency spectrum as used by the Wi-Fi AP 150. The small cell 102’, employing NR in an unlicensed frequency spectrum, may boost coverage to and / or increase capacity of the access network.
[0029] A base station 102, whether a small cell 102’ or a large cell (e.g., macro base station) , may include an eNB, gNodeB (gNB) , or another type of base station. Some base stations, such as gNB 180 may operate in a traditional sub 6 GHz spectrum, in millimeter wave (mmW) frequencies, and / or near mmW frequencies in communication with the UE 104. When the gNB 180 operates in mmW or near mmW frequencies, the gNB 180 may be referred to as an mmW base station. Extremely high frequency (EHF) is part of the RF in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 millimeter and 10 millimeters. Radio waves in the band may be referred to as a millimeter wave. Near mmW may extend down to a frequency of 3 GHz with a wavelength of 100 millimeters. The super high frequency (SHF) band extends between 3 GHz and 30 GHz, also referred to as centimeter wave. Communications using the mmW / near mmW radio frequency band (e.g., 3 GHz -300 GHz) has extremely high path loss and a short range. The mmW base station 180 may utilize beamforming 182 with the UE 104 to compensate for the extremely high path loss and short range.
[0030] The base station 180 may transmit a beamformed signal to the UE 104 in one or more transmit directions 108a. The UE 104 may receive the beamformed signal from the base station 180 in one or more receive directions 108b. The UE 104 may also transmit a beamformed signal to the base station 180 in one or more transmit directions. The base station 180 may receive the beamformed signal from the UE 104 in one or more receive directions. The base station 180 / UE 104 may perform beam training to determine the best receive and transmit directions for each of the base station 180 / UE 104. The transmit and receive directions for the base station 180 may or may not be the same. The transmit and receive directions for the UE 104 may or may not be the same.
[0031] The EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a Serving Gateway 166, a Multimedia Broadcast Multicast Service (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC) 170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may be in communication with a Home Subscriber Server (HSS) 174. The MME 162 is the control node that processes the signaling between the UEs 104 and the EPC 160. Generally, the MME 162 provides bearer and connection management. All user Internet protocol (IP) packets are transferred through the Serving Gateway 166, which itself is connected to the PDN Gateway 172. The PDN Gateway 172 provides UE IP address allocation as well as other functions. The PDN Gateway 172 and the BM-SC 170 are connected to the IP Services 176. The IP Services 176 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS) , a PS Streaming Service, and / or other IP services. The BM-SC 170 may provide functions for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS transmission, may be used to authorize and initiate MBMS Bearer Services within a public land mobile network (PLMN) , and may be used to schedule MBMS transmissions. The MBMS Gateway 168 may be used to distribute MBMS traffic to the base stations 102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service, and may be responsible for session management (start / stop) and for collecting eMBMS related charging information.
[0032] The core network 190 may include a Access and Mobility Management Function (AMF) 192, other AMFs 193, a location management function (LMF) 198, a Session Management Function (SMF) 194, and a User Plane Function (UPF) 195. The AMF 192 may be in communication with a Unified Data Management (UDM) 196. The AMF 192 is the control node that processes the signaling between the UEs 104 and the core network 190. Generally, the SMF 194 provides QoS flow and session management. All user Internet protocol (IP) packets are transferred through the UPF 195. The UPF 195 provides UE IP address allocation as well as other functions. The UPF 195 is connected to the IP Services 197. The IP Services 197 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS) , a PS Streaming Service, and / or other IP services.
[0033] The base station may also be referred to as a gNB, Node B, evolved Node B (eNB) , an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS) , an extended service set (ESS) , a transmit reception point (TRP) , or some other suitable terminology. The base station 102 provides an access point to the EPC 160 or core network 190 for a UE 104. Examples of UEs 104 include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA) , a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player) , a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, or any other similar functioning device. Some of the UEs 104 may be referred to as IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heart monitor, etc. ) . The UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology.
[0034] Although the present disclosure may reference 5G New Radio (NR) , the present disclosure may be applicable to other similar areas, such as LTE, LTE-Advanced (LTE-A) , Code Division Multiple Access (CDMA) , Global System for Mobile communications (GSM) , or other wireless / radio access technologies.
[0035] FIG. 2 is a block diagram of a base station 210 in communication with a UE 250 in an access network. In the DL, IP packets from the EPC 160 may be provided to a controller / processor 275. The controller / processor 275 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 275 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs) , RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release) , inter radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification) , and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs) , error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs) , re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs) , demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
[0036] The transmit (TX) processor 216 and the receive (RX) processor 270 implement layer 1 functionality associated with various signal processing functions. Layer 1, which includes a physical (PHY) layer, may include error detection on the transport channels, forward error correction (FEC) coding / decoding of the transport channels, interleaving, rate matching, mapping onto physical channels, modulation / demodulation of physical channels, and MIMO antenna processing. The TX processor 216 handles mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK) , quadrature phase-shift keying (QPSK) , M-phase-shift keying (M-PSK) , M-quadrature amplitude modulation (M-QAM) ) . The coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and / or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator 274 may be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimate may be derived from a reference signal and / or channel condition feedback transmitted by the UE 250. Each spatial stream may then be provided to a different antenna 220 via a separate transmitter 218TX. Each transmitter 218TX may modulate an RF carrier with a respective spatial stream for transmission.
[0037] At the UE 250, each receiver 254RX receives a signal through its respective antenna 252. Each receiver 254RX recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor 256. The TX processor 268 and the RX processor 256 implement layer 1 functionality associated with various signal processing functions. The RX processor 256 may perform spatial processing on the information to recover any spatial streams destined for the UE 250. If multiple spatial streams are destined for the UE 250, they may be combined by the RX processor 256 into a single OFDM symbol stream. The RX processor 256 then converts the OFDM symbol stream from the time-domain to the frequency domain using a Fast Fourier Transform (FFT) . The frequency domain signal comprises a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, and the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station 210. These soft decisions may be based on channel estimates computed by the channel estimator 258. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station 210 on the physical channel. The data and control signals are then provided to the controller / processor 259, which implements layer 3 and layer 2 functionality.
[0038] The controller / processor 259 can be associated with a memory 260 that stores program codes and data. The memory 260 may be referred to as a computer-readable medium. In the UL, the controller / processor 259 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the EPC 160. The controller / processor 259 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0039] Similar to the functionality described in connection with the DL transmission by the base station 210, the controller / processor 259 provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression / decompression, and security (ciphering, deciphering, integrity protection, integrity verification) ; RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
[0040] Channel estimates derived by a channel estimator 258 from a reference signal or feedback transmitted by the base station 210 may be used by the TX processor 268 to select the appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the TX processor 268 may be provided to different antenna 252 via separate transmitters 254TX. Each transmitter 254TX may modulate an RF carrier with a respective spatial stream for transmission. The UL transmission is processed at the base station 210 in a manner similar to that described in connection with the receiver function at the UE 250. Each receiver 218RX receives a signal through its respective antenna 220. Each receiver 218RX recovers information modulated onto an RF carrier and provides the information to a RX processor 270.
[0041] The controller / processor 275 can be associated with a memory 276 that stores program codes and data. The memory 276 may be referred to as a computer-readable medium. In the UL, the controller / processor 275 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets from the UE 250. IP packets from the controller / processor 275 may be provided to the EPC 160. The controller / processor 275 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0042] New radio (NR) may refer to radios configured to operate according to a new air interface (e.g., other than Orthogonal Frequency Divisional Multiple Access (OFDMA) -based air interfaces) or fixed transport layer (e.g., other than Internet Protocol (IP) ) . NR may utilize OFDM with a cyclic prefix (CP) on the uplink and downlink and may include support for half-duplex operation using time division duplexing (TDD) . NR may include Enhanced Mobile Broadband (eMBB) service targeting wide bandwidth (e.g. 80 MHz beyond) , millimeter wave (mmW) targeting high carrier frequency (e.g. 60 GHz) , massive MTC (mMTC) targeting non-backward compatible MTC techniques, and / or mission critical targeting ultra-reliable low latency communications (URLLC) service.
[0043] A single component carrier bandwidth of 100 MHz may be supported. In one example, NR resource blocks (RBs) may span 12 sub-carriers with a sub-carrier bandwidth of 60 kHz over a 0.25 ms duration or a bandwidth of 30 kHz over a 0.5 ms duration (similarly, 50MHz BW for 15kHz SCS over a 1 ms duration) . Each radio frame may consist of 10 subframes (10, 20, 40 or 80 NR slots) with a length of 10 ms. Each slot may indicate a link direction (i.e., DL or UL) for data transmission and the link direction for each slot may be dynamically switched. Each slot may include DL / UL data as well as DL / UL control data. UL and DL slots for NR may be as described in more detail below with respect to FIGs. 5 and 6.
[0044] The NR RAN may include a central unit (CU) and distributed units (DUs) . A NR BS (e.g., gNB, 5G Node B, Node B, transmission reception point (TRP) , access point (AP) ) may correspond to one or multiple BSs. NR cells can be configured as access cells (ACells) or data only cells (DCells) . For example, the RAN (e.g., a central unit or distributed unit) can configure the cells. DCells may be cells used for carrier aggregation or dual connectivity and may not be used for initial access, cell selection / reselection, or handover. In some cases DCells may not transmit synchronization signals (SS) in some cases DCells may transmit SS. NR BSs may transmit downlink signals to UEs indicating the cell type. Based on the cell type indication, the UE may communicate with the NR BS. For example, the UE may determine NR BSs to consider for cell selection, access, handover, and / or measurement based on the indicated cell type.
[0045] FIG. 3 illustrates an example logical architecture of a distributed RAN 300, according to aspects of the present disclosure. A 5G access node 306 may include an access node controller (ANC) 302. The ANC may be a central unit (CU) of the distributed RAN. The backhaul interface to the next generation core network (NG-CN) 304 may terminate at the ANC. The backhaul interface to neighboring next generation access nodes (NG-ANs) 310 may terminate at the ANC. The ANC may include one or more TRPs 308 (which may also be referred to as BSs, NR BSs, Node Bs, 5G NBs, APs, or some other term) . As described above, a TRP may be used interchangeably with “cell. ”
[0046] The TRPs 308 may be a distributed unit (DU) . The TRPs may be connected to one ANC (ANC 302) or more than one ANC (not illustrated) . For example, for RAN sharing, radio as a service (RaaS) , and service specific ANC deployments, the TRP may be connected to more than one ANC. A TRP may include one or more antenna ports. The TRPs may be configured to individually (e.g., dynamic selection) or jointly (e.g., joint transmission) serve traffic to a UE.
[0047] The local architecture of the distributed RAN 300 may be used to illustrate fronthaul definition. The architecture may be defined that support fronthauling solutions across different deployment types. For example, the architecture may be based on transmit network capabilities (e.g., bandwidth, latency, and / or jitter) . The architecture may share features and / or components with LTE. According to aspects, the next generation AN (NG-AN) 310 may support dual connectivity with NR. The NG-AN may share a common fronthaul for LTE and NR.
[0048] The architecture may enable cooperation between and among TRPs 308. For example, cooperation may be preset within a TRP and / or across TRPs via the ANC 302. According to aspects, no inter-TRP interface may be needed / present.
[0049] According to aspects, a dynamic configuration of split logical functions may be present within the architecture of the distributed RAN 300. The PDCP, RLC, MAC protocol may be adaptably placed at the ANC or TRP.

In some configurations, the DL data portion 504 may be a physical DL shared channel (PDSCH) .
[0052] The DL-centric slot may also include a common UL portion 506. The common UL portion 506 may sometimes be referred to as an UL burst, a common UL burst, and / or various other suitable terms. The common UL portion 506 may include feedback information corresponding to various other portions of the DL-centric slot.

The common UL portion 506 may include additional or alternative information, such as information pertaining to random access channel (RACH) procedures, scheduling requests (SRs) , and various other suitable types of information.
[0053] As illustrated in FIG. 5, the end of the DL data portion 504 may be separated in time from the beginning of the common UL portion 506. This time separation may sometimes be referred to as a gap, a guard period, a guard interval, and / or various other suitable terms. This separation provides time for the switch-over from DL communication (e.g., reception operation by the subordinate entity (e.g., UE) ) to UL communication (e.g., transmission by the subordinate entity (e.g., UE) ) . One of ordinary skill in the art will understand that the foregoing is merely one example of a DL-centric slot and alternative structures having similar features may exist without necessarily deviating from the aspects described herein.

[0055] As illustrated in FIG. 6, the end of the control portion 602 may be separated in time from the beginning of the UL data portion 604. This time separation may sometimes be referred to as a gap, guard period, guard interval, and / or various other suitable terms.

[0056] In some circumstances, two or more subordinate entities (e.g., UEs) may communicate with each other using sidelink signals. Real-world applications of such sidelink communications may include public safety, proximity services, UE-to-network relaying, vehicle-to-vehicle (V2V) communications, Internet of Everything (IoE) communications, IoT communications, mission-critical mesh, and / or various other suitable applications. Generally, a sidelink signal may refer to a signal communicated from one subordinate entity (e.g., UE1) to another subordinate entity (e.g., UE2) without relaying that communication through the scheduling entity (e.g., UE or BS) , even though the scheduling entity may be utilized for scheduling and / or control purposes.

[0057] FIG. 7 is a diagram 700 illustrating an example wireless communication system including a base station and a UE. In this example, a UE 704 is connected to a base station 702 on a cell 706.
[0058] In 3GPP networking, energy usage is a factor that needs to be taken into account. In such scenarios, energy related information can be leveraged to understand the energy usage.
[0059] In some embodiments, the energy related information may include one or more of the following:
[0060] 1) Energy consumption;
[0061] 2) Energy efficiency;
[0062] 3) Carbon emissions;
[0063] 4) Energy source.
[0064] In certain embodiments, energy consumption may include non-renewable energy consumption, renewable energy consumption, or a combination of both. Correspondingly, the energy source may include non-renewable source, renewable source, or a mix of both. For example, renewable energy sources (Green energy) may include wind energy, solar energy, among others, whereas non-renewable energy sources (Grey energy) may include coal energy, oil energy, natural gas energy, and so on.
[0065] The energy related information may be collected within a predetermined dimension. For example, the energy related information may be collected per a network slice set, per a network entity set or per a UE set. The network slice set may include a network slice or a group of network slices, the network entity set may include a network entity or a group of network entities, and the UE set may include a UE or a group of UE. A network entity may be a 5G Network (NW) element or a 6G NW element.
[0066] Network Slicing refers to the technology of partitioning a physical network into multiple virtual, end-to-end networks, enabling the creation of multiple logically isolated virtual networks over a shared physical network infrastructure. Each network slice represents an independent virtual network, where all components within a slice, are logically separated from those of other slices. Network slicing allows for flexible configuration based on the requirements of different users or services, meeting the diverse network needs across various business scenarios.
[0067] Monitoring and Exposure of energy related Information: To optimize energy usage, such as reducing the total energy consumed in providing communication services or decreasing the overall carbon emissions associated with these services, one or more network elements / functions (including Policy Control Functions, PCFs) need to monitor, measure, and track this information. Based on the received information (which may be called first information) , the one or more network elements / functions may check whether energy related criteria is met (e.g., energy efficiency is > a threshold) . If the criteria is not met, it may trigger procedures to change the network configuration in order to make the criteria changes from “not met” to “met” . Furthermore, the energy related information may need to be exposed (either unsolicitedly or solicitedly) to other network elements / functions. For example, the PCF may expose the energy related information to an Session Management Function (SMF) .
[0068] Network slice related policy control
[0069] As mentioned earlier, energy related information may be collected within a network slice dimension. A network slice of a PDU session related policy control may support functions such as collecting, monitoring, tracking, measuring, reporting, and notifying energy related information, as well as updating policies based on the information. In certain embodiments, updates related to reporting or notification may be sent to a UE, for example, the UE 704.
[0070] An operator network element, such as a PCF, Application Function (AF) , Network Data Analytics Function (NWDAF) , SMF, Access and Mobility Management Function (AMF) , Charging Function (CHF) , Network Repository Function (NRF) , or others, may collect and / or monitor energy related information for a network slice of a PDU session. Furthermore, Energy Function (EF) , a new 3GPP network entity, may also be introduced to collect and / or monitor energy related information for a network slice of a PDU session. Then, the EF may transfer the energy related information to the PCF. The reporting and / or notification of the energy related information for a network slice of a PDU session may be exchanged between an operator network entity, an AF, and a service provider of slices, in either direction or both.
[0071] The operator network element, including but not limited to PCF, AF, NWDAF, SMF, AMF, CHF, EF, and NRF, may monitor the energy related information of the network slice and ensure one or more of the following criteria:
[0072] 1) The slice used, selected, or provisioned for a UE is:
[0073] (a) with lower carbon emissions;
[0074] (b) with a higher ratio of renewable energy;
[0075] (c) with less energy consumption; and / or
[0076] (d) with higher energy efficiency;
[0077] AND / OR
[0078] 2) The energy related information does not exceed or fall below specified threshold values, such as:
[0079] (a) carbon emissions of a network slice being greater than or equal to (>=) threshold value “X” ;
[0080] (b) the ratio of renewable energy being less than or equal to (<=) threshold value “Y” ;
[0081] (c) manipulation (calculation) of energy related information resulting in a value greater than or
[0082] equal to (>=) threshold value “Z” , or less than or equal to (<=) threshold value “Z” ; and / or
[0083] (d) any combination of the above conditions.
[0084] Furthermore, if any of the following conditions are met or not met (i.e., energy related criteria / requirements) , the network may take one or more actions to optimize energy usage, such as less carbon emissions or higher ratio of renewable energy, e.g.:
[0085] (1) If a slice of a PDU session currently in use by the UE emits more carbon than an available slice not in use, and the UE could switch to the latter.
[0086] (2) If a slice of a PDU session in use by the UE utilizes less renewable energy than an available slice not in use, and the UE could switch to the latter.
[0087] (3) If a slice of a PDU session in use by the UE emits carbon equal to or above a threshold (X) , while an available slice not in use emits below or equal to that threshold, and the UE could switch to the latter.
[0088] (4) If a slice of a PDU session in use by the UE utilizes renewable energy equal to or below a threshold (Y) , while an available slice not in use utilizes above or equal to that threshold, and the UE could switch to the latter.
[0089] (5) If a network entity, such as User Plane Function (UPF) of a PDU session, in use by the UE emits more carbon than an available network entity not in use, and the UE could switch to utilize the latter.
[0090] (6) If a network entity, such as UPF of a PDU session, in use by the UE utilizes less renewable energy than an available network entity not in use, and the UE could switch to utilize the latter.
[0091] (7) If a network entity, such as UPF of a PDU session, in use by the UE emits carbon equal to or above a threshold (X) , while an available network entity not in use emits below or equal to that threshold, and the UE could switch to utilize the latter.
[0092] (8) If a network entity, such as UPF of a PDU session, in use by the UE utilizes renewable energy equal to or below a threshold (Y) , while an available network entity not in use utilizes above or equal to that threshold, and the UE could switch to utilize the latter.
[0093] In these cases, the network entity (e.g. SMF) may take one or more actions to facilitate the switch and optimize carbon emissions or renewable energy usage. These actions may include:
[0094] (1) Initiating the network-initiated Packet Data Unit (PDU) session release procedure. When the UE re-initiates the PDU session establishment procedure, one or more of the UPF nodes associated with the new PDU session will differ from those of the released PDU session, resulting in an adjustment to the User Plane (UP) path.
[0095] (2) Initiating the network-initiated PDU session modification procedure During this procedure, one or more of the UPF nodes associated with the PDU session before modification will differ from those after modification, also leading to an adjustment in the UP path.
[0096] In other words, to enhance operations and procedures related to energy usage, such as energy saving or improving energy efficiency, the UP path of the PDU session may be adjusted, according to predetermined energy related criteria / requirements.
[0097] In summary, a network element / function (e.g., PCF, AF, NWDAF, SMF, AMF, CHF, EF, NRF, among others) may monitor / collect / acquire (either solicitedly or unsolicitedly) the energy related information of a network slice associated with one or more UPFs of a PDU session of a UE. When an energy related target condition is not satisfied, this network element / function (maybe SMF itself or a network element / function other than SMF, e.g., the PCF, AF, NWDAF, , AMF, CHF, EF, NRF) may trigger the SMF to initiate either the PDU session release procedure or the PDU session modification procedure, based on the energy related information monitored / collected / acquired by this network element.
[0098] Furthermore, the threshold values regarding the energy related information (e.g., X value and Y value) may be determined based on one or more of the following factors:
[0099] (1) Operator policy, such as Service Level Agreements (SLAs) related to specific network slices;
[0100] (2) Service provider input, including SLAs;
[0101] (3) UE-indicated preferences or values associated with energy related information;
[0102] (4) User input, for example, user consent or a preference for being served by a slice with carbon emissions ≤ X value;
[0103] (5) Subscription information, which may specify the use of a slice with renewable energy ≥ Y value.
[0104] FIG. 8 is a diagram illustrating an example architecture 800 for adjustment of a user plane path. As shown in FIG. 8, a PDU session may create a data link from a UE 804, through a Radio Access Network (RAN) 808, some User Plane Functions (UPFs) such as UPF1 810, UPF2 812-a and UPF3 814, ultimately to a data network (DN) 802 such as Internet.
[0105] During the UP path adjustment, the endpoints of the path -specifically, the UE 804 and the DN 802 -remain unchanged, as the primary function of the PDU session is to relay data between them. However, the intermediate nodes, such as the RAN 808 and the UPFs, can undergo changes. For example, the path may switch from a path using UPF2 812-a to one using UPF2’ 812-b. Alternatively, the path could be rerouted from a high-power base station to a low-power one.
[0106] In such a scenario, changing the UPF essentially means switching to a different router, for example, one with lower energy consumption. In 3GPP networking, taking energy related information into account, the networking process fundamentally involves selecting the optimal routing path between the endpoints. In other words, the decision on which UPF / router to use is based on energy related information, with the aim of meeting predetermined energy related criteria / requirements.
[0107] The energy related information may include absolute energy consumption, energy efficiency (such as Gigabytes (GBs) of data transmitted per unit of energy) , and carbon emissions. The predetermined energy related criteria / requirements, for example, may prioritize routers that consume less energy, exhibit higher energy efficiency, or emit lower levels of carbon. Furthermore, the type of energy source (renewable versus non-renewable, e.g., we may require the non-renewable energy ratio is > 50%) is also a significant factor to consider.
[0108] The energy related information may be monitored or measured per network slice, per network entity (like UPF) , or per UE. Optimizing energy usage may involve considering the entire path from the UE 804 to the DN 802.
[0109] As shown in FIG. 8, the SMF 806 may establish the PDU session through interactive control / signaling between the UE 804 and the SMF 806, thereby setting up the PDU session between the UE 804 and the DN 802.
[0110] Furthermore, the decision to adjust the path is typically made by network functions such as the SMF 806 or other network elements. In other words, the SMF 806 can actively monitor energy related information and decide whether to adjust based on that information. Alternatively, another network element, such as an EF or PCF, may monitor energy related information and trigger the release or modification of the PDU session initiated by the SMF 806 by notifying information which is generated based on the energy related information to the SMF 806. The SMF 806 can then passively execute instructions to adjust the path.
[0111] For example, as shown in FIG. 8, assuming that the UPF2 812-a utilizes 100%Grey energy, while the UPF2’ 812-b utilizes 50%Green energy such as solar energy, the SMF 806 may adjust the path accordingly based on energy related information. During the night, when no solar energy is available in the UPF2’ 812-b, either UPF2 812-a or UPF2’ 812-b may be utilized depending on other factors. However, during daytime, when the solar panels in the UPF2’ 812-b become active, a condition requiring lower carbon emissions is triggered, and a switch from the UPF2 812-a to UPF2’ 812-b occurs to take advantage of the renewable energy source.
[0112] Policy control may be implemented per network slice of a PDU session, allowing for tailored energy management. For example, ensuring a network slice’s carbon emissions does not exceed a threshold or that its renewable energy usage is above a certain percentage.
[0113] When a condition is triggered (e.g., carbon emissions exceeding a limit) , the SMF 806 may release and modify the PDU session with a more favorable UPF. This process ensures the UP path is optimized based on energy related criteria.
[0114] Energy related criteria / requirement may be provided from various sources. For example, service providers like power companies may provide energy related criteria / requirement, which operators can use to make the decisions. On the other hand, users may also indicate their preferences regarding carbon emissions or energy efficiency, which are stored in the subscription information database and considered during network optimization.
[0115] FIG. 9 is a flow chart 900 of a process for 3GPP networking based on energy related information. At block 902, a first information is received from a first network entity or function. The first information may be generated by the first network entity or function based on an energy related information.

[0116] At block 904, one or more session management procedures are triggered based on the first information or a determination result based on the energy related information. In some embodiments, the one or more session management procedures may include a packet data unit (PDU) session release procedure or a PDU session modification procedure.

In some embodiments, the energy consumption may include non-renewable energy consumption, renewable energy consumption, or a combination of the non-renewable energy consumption and renewable energy consumption. In some embodiments, the energy source may include non-renewable source, renewable source, or a mix of the non-renewable energy source and the renewable energy source.
[0118] In some embodiments, the first information may also be generated based on the determination result. The determination result may be generated based on whether an energy related criteria related with the energy related information is met or is not met. For example, the energy related criteria may include: energy consumption is over, equal or under a first value, energy efficiency is over, equal or under a second value, carbon emission is over, equal or under a third value, and renewable or non-renewable energy source is over, equal or under a fourth value.
[0119] In some embodiments, the energy related criteria may be determined by (1) an operator policy; (2) a service provider input; (3) a user equipment indicated preference or value associated with the energy related information; (4) a user input; or (5) subscription information.
