Abstract
Description
Technical Field
[0001] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for system information acquisition by energy harvesting devices. Background Art
[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).
[0003] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. The UE may communicate with the network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).
[0004] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink, using CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0027] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functions, or structures and functions in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.
[0028] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0029] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).
[0030] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, as well as other examples. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). For another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).
[0031] In some examples, the network node 110 is or includes a network node (such as an RU) that communicates with the UE 120 via a radio access link. In some examples, the network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, the network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.
[0032] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to a coverage area of the network node 110 and / or a network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).
[0033] In some aspects, the term "base station" or "network node" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near-RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions, such as those described herein in conjunction with the network node 110. In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions, but not another base station function. In this way, a single device may include more than one base station.
[0034] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown, a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.
[0035] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).
[0036] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.
[0037] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station and / or a subscriber unit. UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node and / or any other suitable device configured to communicate via a wireless or wired medium.
[0038] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0039] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.
[0040] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using network node 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.
[0041] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FRI (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that, although a portion of FRI is greater than 6 GHz, FR1 is often (interchangeably) referred to as a "below 6 GHz" band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as a "millimeter wave" band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU).
[0042] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, so the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.
[0043] In view of the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term can be broadly referred to as frequencies that can be lower than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term can be broadly referred to as frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or can be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.
[0044] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive from a network node a first system information block (SIB) indicating an EH capability category (also referred to as an EH category) supported by the network node; and receive from the network node and based at least in part on receiving the first SIB and the UE being associated with the EH category a second SIB having one or more SIB characteristics based at least in part on the EH category. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0045] In some aspects, the network node may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send a first SIB indicating an EH category supported by the network node; and send a second SIB having one or more SIB characteristics based at least in part on the EH category. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0046] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.
[0047] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.
[0048] At the network node 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQI) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-decoding) on data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).
[0049] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.
[0050] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.
[0051] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components).
[0052] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figures 4 to 10 ) or any aspects of any of the methods described herein.
[0053] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform the operations described herein (e.g., with reference to Figures 4 to 10 ) or any aspects of any of the methods described herein.
[0054] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the network node 110 may perform one or more techniques associated with system information acquisition by the EH device, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Figure 7 The process of 700 Figure 8 800 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, conversion and / or interpretation), may cause one or more processors, UE 120 and / or network node 110 to perform or direct, for example, Figure 7 The process of 700 Figure 8 The process 800 of and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.
[0055] In some aspects, the UE includes a component for receiving a first SIB from a network node indicating an EH category supported by the network node; and / or a component for receiving a second SIB having one or more SIB characteristics based at least in part on the EH category from the network node and at least in part on receiving the first SIB and the UE being associated with the EH category. The components for the UE to perform the operations described herein may include, for example, one or more of the following: the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.
[0056] In some aspects, the network node includes means for transmitting a first SIB indicating an EH category supported by the network node; and / or means for transmitting a second SIB having one or more SIB characteristics based at least in part on the EH category. In some aspects, means for the network node to perform operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.
[0057] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.
[0058] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.
[0059] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also called an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs or a combination thereof).
[0060] An aggregated base station (e.g., an aggregated network node) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) can be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU can be implemented within a network node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually distributed across one or more other network nodes. The DU can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.
[0061] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.
[0062] Figure 3 3 is a diagram illustrating an example decomposed base station architecture 300 according to the present disclosure. The decomposed base station architecture 300 may include a CU 310, which may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed control units (such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via respective midhaul links (such as via an F1 interface). Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective RF access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.
[0063] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces, the one or more interfaces being configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, or both.
[0064] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.
[0065] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional split such as defined by 3GPP. In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as by one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.
[0066] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering based on functional splitting (e.g., functional splitting defined by 3GPP) (such as lower layer functional splitting). In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane communications and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).
[0067] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTRIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.
[0068] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.
[0069] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received at the SMO framework 305 or the non-RT RIC 315 from a non-network data source or from a network function. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).
[0070] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.
[0071] Figure 4 4 is a diagram illustrating an example 400 of sending and acquiring system information according to the present disclosure. Figure 4 As shown in , the network node 110 and the UE 120 may communicate with each other. For example, the network node 110 may send system information to the UE 120 to enable communication between the UE 120 and a network accessed via the network node 110.
[0072] As indicated by reference numeral 405, the network node may transmit and the UE may receive a master information block (MIB). The network node transmits the MIB in broadcast form via a physical broadcast channel (PBCH). The network node 110 may periodically transmit the MIB so that the MIB may be periodically received by the UE and used, for example, for cell selection. The MIB may include information about a control resource set (CORESET) and a physical downlink control channel (PDCCH) search space for receiving and decoding SIBs (such as SIB 1).
[0073] As shown by reference numeral 410, the network node may send and the UE may receive SIB1. Collectively, the MIB and SIB1 may be referred to as minimum system information (MSI), and the separate SIB1 may be referred to as remaining minimum system information (RMSI). The network node may send SIB1 via PDCCH communication. As noted herein, the MIB includes parameters for the UE to decode SIB1, which includes cell-specific information specifying parameters for the UE to access the corresponding cell. SIB 1 also includes information indicating the availability and scheduling of other SIBs (e.g., SIB 2 to SIB 9), such as periodicity and system information window size. SIB 1 may also indicate whether other SIBs are provided periodically and / or on demand. If other SIBs can be used on demand, SIB1 may also include information that enables the UE to perform a system information request for an on-demand SIB.
[0074] As indicated by reference numeral 415, the network node 110 may periodically send and the UE 120 may periodically receive other SIBs, such as SIB 1 to SIB 9 (e.g., based on information provided in SIB 1). The other SIBs include system information other than the MSI, which may be used by the network node 110 and the UE 120 for communication. For example, SIB2, SIB3, SIB4, and SIB5 may include information for various types of cell reselection procedures, SIB6, SIB7, and SIB8 may include information associated with various warning and / or alarm notifications, and SIB9 may include timing information. The network node may send the other SIBs via a physical downlink shared channel (PDSCH) communication. As noted herein, the network node may periodically send none, some, or all of the other SIBs.
[0075] As indicated by reference numeral 420, UE 120 may send and network node 110 may receive a system information request. For example, where SIB1 indicates that network node 110 can send one or more of the other SIBs on demand, the UE may request one or more of the other SIBs using information included in SIB1.
[0076] As indicated by reference numeral 425, the network node 110 may send and the UE 120 may receive one or more of the other SIBs based on the system information request. On-demand SIBs may include the same information as corresponding periodic SIBs, but these on-demand SIBs may be requested and sent on demand.
[0077] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4The examples described are different.
[0078] Figure 5 is a diagram illustrating an example 500 of radio frequency (RF) energy harvesting according to the present disclosure. Figure 5 As shown in , an RF receiver (e.g., UE 120) can receive signals (e.g., radio signals carried on radio waves) from an RF transmitter (e.g., network node 110 or UE 120) and convert the electromagnetic energy of these signals into direct current for use by the RF receiver (e.g., using a rectenna including a dipole antenna with an RF diode).
[0079] As shown by reference numeral 505, in some aspects, the RF receiver can use a split receiver architecture in which a first set of antennas is configured to harvest energy and a second set of antennas is configured to receive data. In this case, each set of antennas can be individually configured to receive signals at certain times, frequencies, and / or via one or more specific beams, such that all signals received by the first set of antennas are harvested to obtain energy and all signals received by the second set of antennas are processed to receive information.
[0080] As shown in reference numeral 510, in some aspects, the RF receiver can use a time switching architecture to collect energy. The time switching architecture can use one or more antennas to receive signals, and whether these signals are collected to obtain energy or processed to receive information depends on the time when the signals are received. For example, one or more first time slots can be time slots during which the received signals are transmitted to one or more EH components to collect energy, and one or more second time slots can be time slots during which the received signals are processed and decoded to receive information. In some aspects, the time slots can be preconfigured (e.g., by an RF receiver, an RF transmitter, or another device).
[0081] As shown by reference numeral 515, in some aspects, the RF receiver can use a power distribution architecture to harvest energy. The power distribution architecture can use one or more antennas to receive signals, and these signals are processed by one or both of the EH component and / or the information receiving component according to the EH rate. For example, the RF receiver can be configured to use a first portion of the received signal for EH and use the remaining received signal for information reception. In some aspects, the EH rate can be preconfigured (e.g., by the RF receiver, the RF transmitter, or another device).
[0082] The energy harvested by the RF receiver can be used and / or stored for later use. For example, in some aspects, the RF receiver can be powered directly by the harvested energy. In some aspects, the RF receiver can use an energy storage device (such as a battery, capacitor, and / or supercapacitor) to gather and store the harvested energy for immediate and / or later use.
[0083] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different. In some aspects, a UE (e.g., UE 120) can harvest energy in other ways, alone or in combination with RF energy harvesting. For example, a UE can use solar energy harvesting (e.g., using solar panels to convert sunlight into energy), thermal energy harvesting (e.g., using thermoelectric generators to convert heat into energy), and / or mechanical energy harvesting (e.g., using electromagnetic induction to convert vibrations or other physical movements into energy), etc. to harvest energy for storage and / or for actively powering the UE.
[0084] Some EH UEs are able to communicate (e.g., with other UEs and / or network nodes), but require power to send and / or receive communications. There are a variety of different types of EH UEs with a range of capabilities, which may depend on, for example, how much energy the UE can store, how quickly the UE can recharge energy, and how much energy the UE uses to perform various actions. Due to the nature of EH, some EH UEs may not have power available to communicate in the same manner as other UEs that do not rely on EH, which may cause communications with EH UEs to be intermittent. For example, larger communications (e.g., larger transport blocks) may require more energy to receive and process than smaller communications (e.g., smaller transport blocks), and communications that take more time may require more energy to receive and process than relatively shorter communications. This may cause communications with EH UEs to drop, or even cause some UEs to be unable to handle certain types of communications that exceed the capabilities of the EH UE.
[0085] The limited capabilities of some EH UEs may also be problematic when operating in idle mode, since the idle UE and the network have not yet established any connection to coordinate operation. In this case, a predefined procedure (e.g., duty cycle transmission) may enable the exchange of system information to facilitate establishing communications between the network and the UE, but this may consume significant network resources and result in lower performance for some EH UEs that may be more capable than other EH UEs. Issues associated with delivering system information to the UE, including latency, may negatively impact how quickly and efficiently the UE can establish communications with the network, and may prevent some UEs from being able to receive system information in its entirety.
[0086] Some techniques and apparatus described herein enable an EH UE to obtain system information in a manner that accounts for different capabilities of the EH UE. For example, a network node may send a first SIB (e.g., SIB-EH) specific to an EH device. SIB-EH may indicate which EH category(s) the network node supports, so that the EH UE may receive additional system information in a SIB having one or more characteristics based on the UE's EH category. This may enable the network node to send different SIBs for UEs associated with different EH categories, and enable the UE to receive and process SIBs customized for the UE's EH category. Thus, the UE may obtain system information in a manner that accounts for the impact that the EH has on the UE's capabilities. In this way, the network node and the EH UE may communicate system information more efficiently (e.g., relative to relying on legacy SIBs and / or duty cycle transmissions), better support EH UEs with lower capabilities to obtain system information, and have fewer dropped communications between the network node and the EH UE, etc.
[0087] Figure 6 6 is a diagram of an example 600 associated with system information acquisition by an EH device according to the present disclosure. Figure 6 As shown in , a network node (e.g., network node 110) can communicate with one or more UEs (e.g., a first UE, a second UE, and a third UE 120). In some aspects, the UE and the network node can be part of a wireless network (e.g., wireless network 100). The UE can operate in an idle mode (e.g., not connected and / or not yet communicating with a network node). Example UEs include a first UE not associated with an EH (e.g., UE (no EH)), a second UE associated with a first EH category (e.g., UE (EH1)), and a third UE associated with a second EH category (e.g., UE (EH2)).
[0088] As shown by reference numeral 605, the network node may send and one or more of the UEs may receive the MIB. For example, as described herein, the network node may broadcast the MIB via the PBCH, and the MIB may be received by one or more of the UEs. The MIB may include information associated with one or more parameters that may be used by the UE to receive SIB 1 and / or SIB-EH. Although this example depicts that one MIB is received by each example UE and thus includes parameters for receiving both SIB1 (e.g., for the first UE) and SIB-EH (e.g., for the second UE and the third UE), in some aspects, the SIB-EH may be associated with a separate MIB. In this case, the MIB received by the first UE will be different from the MIB received by the second UE and the third UE. In some aspects, when multiple MIBs are used, the UE may be configured to monitor a specific MIB corresponding to the type of UE. For example, the first UE may be configured to monitor only the first MIB carrying information for receiving the SIB, while the second UE and the third UE may be configured to monitor only the second MIB carrying information for receiving the SIB-EH. Any number of separate MIBs may be configured (eg, for different EH classes), and a UE may be configured to monitor any number of MIBs (eg, not just the MIB associated with the UE's EH class).
[0089] As shown by reference numeral 610, the network node may send and one or more of the UEs may receive the SIB-EH. In this example, a first UE that is not associated with an EH category does not receive the SIB-EH because the first UE may instead receive SIB 1 (e.g., as described herein with reference to 620). Both the second UE and the third UE receive the SIB-EH based at least in part on receiving the corresponding MIB. For example, the second UE and the third UE may decode the MIB to obtain one or more parameters for decoding the SIB-EH, and then use these parameters to decode the SIB-EH. In some aspects, the SIB-EH is received via the PDCCH, and the resources carrying the SIB-EH are indicated by the corresponding MIB. Although this example depicts different UEs of different EH categories receiving the same SIB-EH, in some aspects, different SIB-EHs may be sent for different EH categories.
[0090] In some aspects, the SIB-EH indicates one or more EH categories supported by the network node. For example, the network node may be configured to communicate with UEs associated with multiple different EH categories. In this case, the SIB-EH may indicate each EH category in the supported EH categories (e.g., at least EH1 and EH2 in example 600).
[0091] In some aspects, the EH category may be pre-configured and / or defined by a specification. In some aspects, the EH category may be based on capabilities or characteristics of the EH UE. For example, the EH category may be defined based on a maximum number of communications (e.g., transmissions and / or receptions) that the UE can perform with a full charge, a charging rate of the UE, and / or a duration (e.g., average duration) to obtain a full charge.
[0092] In some aspects, different EH categories may be associated with different SIB characteristics, which may enable UEs of different EH categories to obtain system information in different ways. For example, for an EH-specific SIB, the SIB characteristic may indicate whether the EH-specific SIB is to be transmitted via one or multiple transport blocks (TBs). Although multiple TBs may take more time to transmit, some large TBs may be too large for some EH UEs to receive reliably, and dividing the TB into multiple smaller TBs may provide the UE with time to collect energy between transmissions. Another example SIB characteristic may include parameters based at least in part on the EH category. For example, some EH-specific SIBs may include certain parameters related only to the corresponding EH category, such as parameters for indicating how many PDSCH opportunities the EH UE can monitor before recharging. As another example, for parameters, the SIB characteristic may include specific parameter values based at least in part on the EH category. For example, a parameter indicating a random access channel (RACH) interval, a parameter indicating a maximum TB size, and / or a parameter indicating the maximum number of PDSCH opportunities that can be monitored when fully charged, etc., may be different for different EH categories.
[0093] In some aspects, SIB-EH may indicate one or more resources via which EH-specific SIB 1 (e.g., SIB1-EH1 and / or SIB1-EH2) is to be transmitted and / or one or more parameters associated with receiving EH-specific SIB 1. For example, SIB-EH may indicate PDSCH resources for receiving SIB 1-EH 1 and / or SIB1-EH2.
[0094] In some aspects, for an EH class, the SIB-EH may indicate which SIBs may be capable of being used on demand. For example, in addition to or as an alternative to periodically sending each EH-specific SIB, a network node may be capable of sending an EH-specific SIB on demand. In this case, the SIB-EH may include information that enables the UE to request one or more of the SIBs that can be used on demand, such as how to send a request for any given EH-specific SIB. In some aspects, any or all of the EH-specific SIBs may be capable of being used on demand. In some aspects, whether an EH-specific SIB can be used on demand may also depend on the EH class (e.g., an on-demand SIB may be supported by some EH classes but not by other EH classes).
[0095] In some aspects, the EH categories supported by the network node may be based at least in part on radio conditions (e.g., cell load) associated with the network node. For example, if the cellular load on the network node is relatively high, the network node may support fewer EH categories than when the cellular load is relatively low. As conditions change, the network node may dynamically change which EH categories are supported, and any changes may be reflected in the SIB-EH.
[0096] As indicated by reference numeral 615, at least one of the UEs may send, and the network node may receive, a system information request. For example, based at least in part on the SIB-EH indicating that another SIB (e.g., SIB 1-EH1) can be used on demand, the second UE may send a system information request (e.g., using information included in the SIB-EH). In some aspects, the system information request may indicate that the second UE is requesting SIB 1-EH 1. In some aspects, the system information request may include a request for any number of SIBs, EH-specific SIBs, and / or other SIBs. In some aspects, multiple system information requests may be sent (e.g., one request for each on-demand SIB in any number of on-demand SIBs, EH-specific on-demand SIBs, and / or other on-demand SIBs).
[0097] In some aspects, the system information request may be included in a PRACH message (e.g., a random access message or Msg 1). For example, the request may be included in a preamble associated with the corresponding EH category. In some aspects, the system information request may be included in a physical uplink shared channel (PUSCH) message (e.g., Msg3) associated with a RACH procedure. For example, the system information request may be indicated by a medium access control (MAC) control element included in the PUSCH message. In this case, the MAC control element may indicate the requested SIB (e.g., SIB1-EH1) and the EH category (e.g., EH1) of the first UE. In this way, the network node can handle EH-specific system information requests while also performing a RACH procedure.
[0098] As shown by reference numeral 620, the network node may send and at least one UE (e.g., a first UE) may receive SIB1. For example, in this example, SIB1 may be periodically sent because the first UE did not request SIB1. In this example, SIB1 is not EH specific because the network node can support different types of SIBs (EH specific SIBs and / or other SIBs). As described herein, SIB1 includes RMSI that includes cell-specific information that enables the first UE to communicate with the network node and access the corresponding cell. SIB1 may also include information indicating the availability and scheduling of other SIBs and which other SIBs can be used on demand.
[0099] As shown by reference numeral 625, the network node may send and at least one UE (e.g., a second UE) may receive an EH-specific SIB1 (e.g., SIB1-EH1) having one or more characteristics based at least in part on the EH category of the second UE. For example, SIB1-EH1 may be transmitted in multiple TBs and / or may have one or more parameters specific to the corresponding EH category (e.g., EH1), as described herein. In this example, SIB1-EH1 may be sent on demand to the second UE (e.g., based at least in part on the network node receiving a system information request, as described herein). The second UE may monitor SIB1-EH1 based at least in part on the information including SIB-EH and the second UE being included in the EH category corresponding to SIB1-EH1. Like SIB1, SIB1-EH1 may include RMSI, information indicating the availability and scheduling of other SIBs (EH-specific SIBs or other SIBs), and information indicating which other SIBs can be used on demand, etc.
[0100] As shown by reference numeral 630, the network node may transmit and at least one UE (e.g., a third UE) may receive another EH-specific SIB1 (e.g., SIB1-EH2) having one or more characteristics based at least in part on the EH category of the third UE. In this example, SIB1-EH2 may be periodically transmitted (e.g., the schedule is identified by SIB-EH and is not transmitted in response to a system information request). The third UE may monitor SIB1-EH2 based at least in part on the information including SIB-EH and the third UE being included in the EH category corresponding to SIB1-EH2. Like SIB1 and SIB1-EH1, SIB1-EH2 may include RMSI, information indicating the availability and scheduling of other SIBs (EH-specific SIBs or other SIBs), and information indicating which other SIBs can be used on demand, etc.
[0101] As shown by reference numeral 635, the network node may send and at least one UE (e.g., a first UE and a second UE) may receive another SIB that is not EH specific. In this example, SIB2 is not EH specific, but is received by both the first UE and the second UE. In this case, the second UE may be included in an EH category that is capable of receiving SIB2 without changing one or more SIB characteristics of SIB2. Therefore, the network node may abandon the transmission of SIB2 that is specific to an EH category (e.g., EH1), which may save resources while enabling the second UE to efficiently receive system information included in SIB2. For example, SIB2 may be transmitted in a single TB. In this example, although a system information request for SIB2 is not shown, SIB2 may be transmitted periodically or on demand, like other SIBs.
[0102] As shown by reference numeral 640, the network node may send and at least one UE (e.g., a third UE) may receive another EH-specific SIB (e.g., SIB2-EH2). In this example, SIB2-EH2 is EH-specific and may be sent and / or received in a manner similar to SIB 1-EH2 described herein. In this case, SIB2-EH2 may have one or more characteristics different from SIB2 to enable the third UE to obtain system information obtained within the SIB2-EH2.
[0103] In some aspects, a network node may be configured with information identifying multiple EH-specific SIB sets for transmission to an EH UE, such as an EH-specific SIB set for each EH class. In this case, some EH-specific SIBs may be included in more than one EH-specific SIB set (e.g., if multiple EH classes are capable of receiving the same EH-specific SIB), and some EH-specific SIB sets may include one or more SIBs that are not EH-specific. For example, an EH UE with relatively high capabilities (e.g., for charging, energy storage, and / or communication processing) may be able to receive some SIBs that are not EH-specific, while an EH UE with relatively low capabilities may require most or even all SIBs to be EH-specific.
[0104] By sending different SIBs for UEs associated with different EH capabilities, the UEs can obtain system information in a manner that accounts for the impact that EH has on the capabilities of the UE. In this way, network nodes and EH UEs can communicate system information more efficiently (e.g., relative to relying on legacy SIBs and / or duty cycle transmissions), better support lower-capability EH UEs to be able to obtain system information, and have fewer dropped communications between network nodes and EH UEs, etc.
[0105] As indicated above, Figure 6are provided as examples. Other examples can be found in the Figure 6 The examples described are different.
