Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. non-provisional patent application No. 17 / 820,788, filed on August 18, 2022, entitled “TECHNIQUES FOR DEFERRAL OF WAKE-UP SIGNALING FOR NETWORK NODE SLEEP MODES,” which is hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for deferring wake-up signaling for a network node sleep mode. Background Art

[0004] 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).

[0005] 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. A UE may communicate with a 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 side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0006] These 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, or global level. New Radio (NR), which may also 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 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.

[0028] 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 construed as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the present disclosure will be fully conveyed to those skilled in the art. It should be appreciated 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, functionality, or structures and functionality 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 present invention.

[0029] 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.

[0030] 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 applicable to other RATs, such as 3G RAT, 4G RAT and / or 5G and beyond (e.g., 6G) RATs.

[0031] Figure 1 1 is a diagram illustrating an example of a wireless network 100. The wireless network 100 may be a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. 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), one 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 an example of a network node that communicates with the UE 120. As shown, 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 RAN node (e.g., within a single device or unit). As another example, the network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated 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)).

[0032] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. 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. For example, the network node 110 may include 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.

[0033] 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 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, or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several thousand meters) 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 residence) 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 in , 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).

[0034] In some aspects, the term "base station" or "network node" may refer to an aggregated 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 certain 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 the other. In this way, a single device may include more than one base station.

[0035] 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 communications 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, or a relay, etc.

[0036] 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, or relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, or different effects 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).

[0037] 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.

[0038] UE 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, or a subscriber unit. UE 120 may 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 device, 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, or a satellite radio), an in-vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, or any other suitable device configured to communicate via a wireless or wired medium.

[0039] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, or location tags, which 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, 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 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 operably coupled, communicatively coupled, electronically coupled, or electrically coupled.

[0040] Generally speaking, 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 also be referred to as a radio technology or air interface. Frequency may also be referred to as a carrier or frequency channel. 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.

[0041] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). 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), or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by network node 110.

[0042] Devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, or channels by frequency or wavelength. For example, 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 FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0043] 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 to 24.25GHz). The bands falling within FR3 can inherit FR1 characteristics or FR2 characteristics, and thus the features of FR1 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 to 71GHz), FR4 (52.6GHz to 114.25GHz) and FR5 (114.25GHz to 300GHz). Each of these higher frequency bands falls within the EHF band.

[0044] With these examples in mind, unless otherwise specifically stated, if the term "sub-6 GHz" is used herein, it may broadly refer to frequencies that may be less than 6 GHz, frequencies that may be within FR1, or frequencies that may include mid-band frequencies. Additionally, unless otherwise specifically stated, if the term "millimeter wave" is used herein, it may broadly refer to frequencies that may include mid-band frequencies, frequencies that may be within FR2, FR4, FR4-a, FR4-1, or FR5, or frequencies that may 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, or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0045] In some aspects, UE 120 may include a communication manager 140. As described in greater detail elsewhere herein, the communication manager 140 may receive a first indication that the network node is in a sleep mode; receive a second indication of a periodic WUS opportunity associated with the sleep mode; and receive a third indication for deferring transmission of a WUS associated with data for one or more WUS opportunities, the deferral of the transmission being based at least in part on a latency parameter associated with the data. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0046] In some aspects, the network node 110 may include a communication manager 150. As described in greater detail elsewhere herein, the communication manager 150 may send a first indication that the network node is in a sleep mode; send a second indication of a periodic WUS opportunity associated with the sleep mode; and send a third indication for deferring the transmission of a WUS associated with data for one or more WUS opportunities, the deferral of the transmission being based at least in part on a latency parameter associated with the data. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0047] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0048] Figure 2 2 is a diagram illustrating an example 200 in which a network node 110 communicates with a UE 120 in a wireless network 100. 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.

[0049] 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 use one or more channel quality indicators (CQIs) received from the UE 120 to select one or more modulation and coding schemes (MCSs) for the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 using the MCS selected for the UE 120 and may provide data symbols to 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, 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-coding) on ​​data symbols, control symbols, overhead symbols, 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, 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).

[0050] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 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, 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, or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in a housing.

[0051] 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.

[0052] One or more antennas (e.g., antennas 234a to 234t or antennas 252a to 252r) may include or may be included in one or more antenna panels, one or more antenna groups, one or more antenna element sets, or one or more antenna arrays, etc. An antenna panel, antenna group, antenna element set, or antenna array may include one or more antenna elements (in a single housing or multiple housings), a coplanar antenna element set, a non-coplanar antenna element set, or coupled to one or more transmit or receive components (such as Figure 2 One or more antenna elements of one or more components).

[0053] 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, 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, or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the processes described herein (eg, with reference to Figures 5 to 10 ).

[0054] At the network node 110, uplink signals from the UE 120 or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232, shown as DEMOD), detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted via the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide 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 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, or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the processes described herein (e.g., reference 200 to FIG. 1 ). Figures 5 to 10 ).

[0055] In some aspects, the controller / processor 280 may be a component of a processing system. A processing system may generally be a system or series of machines or components that receives inputs and processes the inputs to produce a set of outputs that may be communicated to other systems or components, such as the UE 120. For example, the processing system of the UE 120 may be a system that includes various other components or subcomponents of the UE 120.

[0056] The processing system of UE 120 may interface with one or more other components of UE 120, may process information (such as input or signal) received from one or more other components, or may output information to one or more other components. For example, a chip or modem of UE 120 may include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some examples, the first interface may be an interface between a processing system and a receiver of the chip or modem, so that UE 120 may receive information or signal input, and may pass information to the processing system. In some examples, the second interface may be an interface between a processing system and a transmitter of the chip or modem, so that UE 120 may send information output from the chip or modem. A person of ordinary skill in the art will readily recognize that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.

[0057] In some aspects, controller / processor 240 may be a component of a processing system. A processing system may generally be a system or series of machines or components that receives inputs and processes the inputs to produce a set of outputs that may be passed to other systems or components, such as network node 110. For example, a processing system of network node 110 may be a system that includes various other components or subcomponents of network node 110.

[0058] The processing system of the network node 110 may interface with one or more other components of the network node 110, may process information (such as input or signal) received from one or more other components, or may output information to one or more other components. For example, a chip or modem of the network node 110 may include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some examples, the first interface may be an interface between a processing system and a receiver of the chip or modem, so that the network node 110 may receive information or signal input, and may pass information to the processing system. In some examples, the second interface may be an interface between a processing system and a transmitter of the chip or modem, so that the network node 110 may send information output from the chip or modem. A person of ordinary skill in the art will readily recognize that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.

[0059] 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 network node 110 may perform one or more techniques associated with deferring wake-up signaling for a sleep mode of the network node, 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, or Figure 2 Any other component (or combination of components) may perform or direct, for example 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 memory 282 may include non-transitory computer-readable media storing one or more instructions (e.g., code or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 or UE 120 (e.g., directly, or after compilation, conversion, or interpretation), may cause the one or more processors, UE 120, or network node 110 to perform or direct, for example, Figure 7 The process of 700 Figure 8 The process 800 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.

[0060] In some aspects, a UE (e.g., UE 120) includes a component for receiving a first indication that a network node is in a sleep mode; a component for receiving a second indication of a periodic WUS opportunity associated with the sleep mode; and / or a component for receiving a third indication for deferring the transmission of a WUS associated with data for one or more WUS opportunities, the deferral of the transmission being based at least in part on a latency parameter associated with the data. The components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0061] In some aspects, a network node (e.g., network node 110) includes means for sending a first indication that the network node is in sleep mode; means for sending a second indication of a periodic WUS opportunity associated with the sleep mode; and / or means for sending a third indication for deferring the transmission of a WUS associated with data for one or more WUS opportunities, the deferral of the transmission being based at least in part on a latency parameter associated with the data. In some aspects, means for a network node to perform operations described herein may include, for example, one or more of the following: communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0062] Although Figure 2 The blocks in the 200 and 210 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.

[0063] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0064] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways with various components or components. 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 NRBS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) performing base station functionality can be implemented as an aggregated base station (also referred to as 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).

[0065] An aggregated base station (e.g., an aggregated network node) may 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) may 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, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may 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.

[0066] 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.

[0067] Figure 33 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 radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0068] 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 configured to receive or transmit 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 transmit signals to one or more of the other units via a wired transmission medium, and the wireless interface being configured to receive signals or transmit signals to one or more of the other units via a wireless transmission medium, or both.

[0069] In some aspects, 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 CU 310. 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, 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, CU 310 may be implemented to communicate with DU 330 for network control and signaling.

[0070] 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 medium access control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to a functional split (such as a functional split defined by 3GPP). In some aspects, the 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 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.

[0071] 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 based on functional splits (e.g., functional splits defined by 3GPP) such as lower layer functional splits, or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. 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 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.

[0072] 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-RT RIC 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-RTRIC 315 configured to support the functionality of the SMO framework 305.

[0073] 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 communicate 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.

[0074] 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 from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. 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).

[0075] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0076] Figure 4 4 is a diagram illustrating an example 400 of a network energy saving mode according to the present disclosure. Figure 4 As shown, the network node can communicate with multiple UEs via a wireless network. In some examples, the network node can support a cell of a wireless network to which the UE connects for wireless communication. Figure 4 As shown, the network node may establish communication links 405 with a plurality of UEs.

[0077] The network node may enter an energy saving mode (e.g., a power saving mode, a demand-based communication mode, and / or a discontinuous reception mode, etc.). The energy saving mode may be selected from a set of available energy saving modes configured to save power at the network node while supporting network operations. Different energy saving modes may be associated with different power consumptions and / or different transition times (e.g., the amount of time to switch between a sleep mode and a wake-up mode). In some networks, the network node may enter a sleep mode based at least in part on traffic conditions. For example, the network node may enter a sleep mode based at least in part on the volume of traffic and / or the periodicity of the traffic satisfying a threshold.

[0078] like Figure 4 As shown, the network node can save energy by entering sleep mode 410 when not receiving traffic. However, in order to maintain awareness of whether one or more linked UEs need to enter a connected state or perform a small data transfer (SDT), the network node can configure a WUS opportunity. During the WUS opportunity, the network node wakes up to monitor WUS from one or more linked UEs.

[0079] like Figure 4 As shown, the network node does not receive a WUS during WUS opportunity 415. Based at least in part on not receiving a WUS during WUS opportunity 415, the network node returns to sleep mode 420 until a subsequent WUS opportunity 425. During WUS opportunity 425, the network node receives a WUS 430 and remains in awake mode 435 until communication with the UE associated with the WUS 430 is completed.

[0080] In example 400, at least one of the plurality of UEs will send a WUS during a WUS opportunity if any of the plurality of UEs has data buffered for transmission to the network node. Depending on the number of UEs supported by the network node in a cell and / or based at least in part on the periodicity of data buffered for transmission at the plurality of UEs, the network node may inefficiently wake up from a sleep mode more frequently than is desired to save power at the network node. In some networks, waking up at each WUS opportunity may consume more energy than remaining in an awake mode based at least in part on the power consumed by activating the RF chain to enter the awake mode.

[0081] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0082] In some aspects described herein, the network node may configure the linked UE to postpone the transmission of the WUS based at least in part on one or more conditions. For example, the network node may configure the UE to postpone the transmission of the WUS based at least in part on a delay requirement and / or a priority requirement that is buffered for transmission (e.g., associated with the transmission of the WUS). Additionally or alternatively, the delay requirement and / or the priority requirement may be associated with the UE. Based at least in part on the time until a subsequent WUS opportunity satisfies the delay requirement and / or the priority requirement, the UE postpones the transmission of the WUS until a subsequent WUS opportunity. In some aspects, the UE may postpone the transmission of the WUS for one or more WUS opportunities based at least in part on one or more conditions.

[0083] In some aspects, a UE may be configured with a deferral condition based at least in part on a buffer status, signal priority, and / or latency requirement, etc. In some aspects, one or more additional UEs may be configured with different deferral conditions based at least in part on a buffer status, signal priority, and / or latency requirement, etc., associated with data of the one or more additional UEs.

[0084] In some aspects, the UE may send a deferral notification to the network node (e.g., in place of a WUS). In some aspects, the deferral notification may be in the same form as the WUS and may have one or more characteristics indicating a deferral notification rather than a request to wake up the network node. For example, the UE may use a WUS opportunity to send a deferral notification and / or may indicate deferral of the WUS based at least in part on a preamble used in the deferral notification.

[0085] Based at least in part on receiving the deferral notification, the network node may determine whether to wake up. For example, the network node may determine to wake up based at least in part on the number of deferral notifications received satisfying a threshold, the amount of time that has elapsed since a previous wake-up time, or the time of day, etc. In some aspects, when the network node wakes up (whether in response to the deferral notification or at a later time), the network node may use the deferral notification along with deferral notifications from other UEs to prioritize resources for UE allocation.

[0086] In some aspects, the network node may send an indication that the network node is awake. For example, the network node may broadcast or multicast an indication that the network node is awake. Based at least in part on receiving the indication that the network node is awake and having data buffered for transmission and for which the WUS is deferred, the UE may send a scheduling request (SR).

[0087] As described herein, a WUS may include signaling configured to request a network node to wake up and support communications with an associated UE. In some aspects, a WUS may include an SR or a message configured as a WUS separate from an SR.

[0088] Based at least in part on configuring the UE to defer sending a WUS based at least in part on satisfaction of a condition, the network node may avoid waking up unnecessarily, may wake up for communication with more UEs for efficient use of wake-up time, and / or may save energy resources of the network node.

[0089] Figure 5 is a diagram of an example 500 associated with wake-up signaling of a network node sleep mode according to the present disclosure. Figure 5 As shown, a network node (e.g., network node 110, CU, DU, and / or RU) may communicate with a UE (e.g., UE 120). In some aspects, the network node and the UE may be part of a wireless network (e.g., wireless network 100). The UE and the network node may be in a Figure 5 The operations shown are performed after a wireless connection has been established.

[0090] As indicated by reference numeral 505, the network node may send, and the UE may receive, configuration information. In some aspects, the UE may receive the configuration information via one or more of RRC signaling, one or more MAC control elements (CEs), and / or downlink control information (DCI), etc. In some aspects, the configuration information may include an indication of one or more configuration parameters for the UE to select (e.g., known to the UE and / or previously indicated by a network node or other network device) and / or explicit configuration information for the UE to configure the UE, etc.

[0091] In some aspects, the configuration information may indicate that the UE is to defer transmission of the WUS based at least in part on a condition. The configuration information may indicate the condition for deferring, the length of the deferral, and / or the type of data associated with the WUS to be deferred, among other things.

[0092] The UE may configure itself based at least in part on the configuration information.In some aspects, the UE may be configured to perform one or more operations described herein based at least in part on the configuration information.

[0093] As indicated by reference numeral 510, the UE may receive, and the network node may send, an indication of conditions for sending a WUS or deferring a WUS.

[0094] As indicated by reference numeral 515, the UE may receive, and the network node may send, an indication of a condition for sending a deferral notification. For example, the UE may be instructed to send a deferral notification the first time the UE defers sending of a WUS. Additionally or alternatively, the UE may be instructed to send a deferral notification at each WUS during which the UE defers sending of a WUS and / or during which the UE has data buffered for sending to the network node.

[0095] As indicated by reference numeral 520, the UE may receive, and the network node may send, an indication that the network node is in sleep mode. In some aspects, the network node may send the indication that the network node is in sleep mode via an RRC message (e.g., to a connected UE upon entering sleep mode), via a system information block (SIB), and / or via a master information block (MIB), among others.

[0096] As indicated by reference numeral 525, the UE may receive and the network node may send an indication of a WUS opportunity associated with the sleep mode. For example, the WUS opportunity may be configured with resources on which the UE may send a WUS and / or SR. The resources may be periodic. In some aspects, the macrocycle may indicate a WUS opportunity in a series of WUS opportunities that is a non-postponed WUS opportunity during which the UE will not postpone the sending of the WUS.

[0097] As indicated by reference numeral 530, the UE may receive and the network node may send an indication for deferring the transmission of a WUS for one or more WUS occasions based at least in part on the conditions for sending the WUS or deferring the WUS. In some aspects, the network node may indicate that the transmission of the WUS is deferred for one or more WUS occasions based at least in part on a latency parameter associated with data associated with the WUS. The indication for deferring the transmission of the WUS may apply to the transmission of the WUS (e.g., all transmissions) during sleep mode because the latency parameter and / or priority of the transmission of the WUS meets the threshold.

[0098] The network node may indicate a configuration selected for deferring the sending of the WUS from a set of candidate configurations indicated in conjunction with reference numerals 505 and / or 510. In some aspects, the selection may be associated with a set of conditions and / or thresholds (e.g., a latency threshold or a priority threshold) associated with a determination to defer or send the WUS.

[0099] In some aspects, one or more of the indications described in conjunction with reference numerals 510 to 530 may be associated with a single communication. For example, the UE may receive the indications described in conjunction with reference numerals 520 to 530 as a single message (e.g., an indication of a sleep mode). In some aspects, the one or more indications may include RRC signaling and / or MAC layer signaling (e.g., one or more MAC CEs).

[0100] The UE may detect that data is buffered for transmission, as indicated by reference numeral 535. For example, an application client associated with the UE may generate data for transmission to an application server via a network node.

[0101] As indicated by reference numeral 540, the UE may detect that the data satisfies the condition for postponing the WUS. For example, the data may be associated with a latency requirement that allows the UE to send the data after skipping one or more WUS opportunities, and / or the data may have a low priority that allows it to be sent later. The data may satisfy the condition for postponing the WUS based at least in part on a latency parameter (e.g., latency requirement) associated with the data.

[0102] In some aspects, the UE may determine to defer transmission of the WUS based at least in part on failure to receive an indication of network node wakeup for one or more WUS opportunities (e.g., as described in conjunction with reference numeral 560), the one or more WUS opportunities being configured for WUS associated with data having a latency requirement that satisfies a threshold, the number of the one or more WUS opportunities satisfying a threshold, and / or the one or more WUS opportunities being configured for WUS associated with data having a priority that satisfies a threshold, etc. In some aspects, the UE may determine to defer transmission of the WUS based at least in part on a buffer status associated with the data and / or a signal priority of the WUS (e.g., a configured priority of the WUS and / or an associated WUS opportunity), etc.

[0103] As indicated by reference numeral 545, the UE may defer transmission of the WUS. For example, the UE may defer transmission of the WUS during the earliest WUS opportunity (e.g., the earliest after detecting that data is buffered for transmission) and / or one or more additional WUS opportunities. The UE may defer transmission based at least in part on one or more characteristics of the data (e.g., latency requirements and / or priority requirements) and / or one or more characteristics of the UE (e.g., priority of the UE and / or capabilities of the UE), etc. In some aspects, deferring transmission of the WUS may be suppressing transmission of the WUS during a WUS opportunity during which the UE is able to transmit the WUS (e.g., the deferral is not based on a lack of ability to transmit during the WUS opportunity).

[0104] In some aspects, the UE may defer transmission of a WUS for one or more activity intervals.An activity interval may include a time period during which a network node is awake to receive one or more WUSs, and may include one or more WUS opportunities.

[0105] As shown by reference numeral 550, the UE may send, and the network node may receive, an indication that the WUS is postponed. In some aspects, the indication that the WUS is postponed may include additional information, such as a priority of the data and / or a maximum postponement time, etc. For example, the indication of postponement may include an indication that the UE has data buffered for transmission and that the UE has determined to postpone transmission for one or more WUS opportunities. In some aspects, the UE may indicate the additional information (e.g., implicitly) via selection of a preamble for the indication. For example, one or more preambles may be associated with different values ​​of the additional information.

[0106] As indicated by reference numeral 555, the network node may determine to wake up. In some aspects, the network node may determine to wake up based at least in part on receiving a number of indications of deferred WUS that satisfy a threshold. In some aspects, the network node may determine to wake up based at least in part on the expiration of a threshold amount of time from receiving an indication of the deferred WUS. In some aspects, the network node may determine to wake up based at least in part on the periodicity of the WUS occasions. For example, if the network node receives any indication that the WUS is deferred during any of the WUS occasions in a cycle (e.g., within the previous 10 WUS occasions), the network node may determine to wake up periodically (e.g., every 10 WUS occasions).

[0107] As indicated by reference numeral 560, the UE may receive, and the network node may send, an indication of the end of the sleep mode (eg, the network node awakens and / or has been awakened). In some aspects, the network node may send the indication via a multicast or broadcast message.

[0108] The UE may send, and the network node may receive, the WUS, as indicated by reference numeral 565.

[0066] In some aspects, the WUS may include a SR indicating a request for resources for sending data.

[0109] In some aspects, the UE may send a WUS (e.g., SR) based at least in part on receiving an indication of the end of the sleep mode. In this case, the WUS may not indicate a request for the network node to wake up because the network node is already awake, and may indicate a request for resource allocation.

[0110] In some aspects, the UE may send a WUS (e.g., SR) in the absence of an indication of the end of sleep mode. In some aspects, the UE may send a WUS based at least in part on the condition for deferring is no longer met. For example, the UE may send a WUS based at least in part on a latency requirement for the data that allows for delays associated with deferring one or more previous WUS opportunities, but does not allow for delays associated with deferring the current WUS opportunity (e.g., the UE has defered a maximum number of WUS opportunities).

[0111] In some aspects, the UE may send a WUS based at least in part on the periodicity of the WUS occasions. For example, the UE may not defer sending a WUS during a periodically scheduled non-deferral WUS occasion (e.g., every 10 WUS occasions). In this way, multiple UEs may use the periodically scheduled non-deferral WUS occasions to send associated WUSs to a network node, and the network node may wake up to communicate with the multiple UEs.

[0112] As indicated by reference numeral 570, the network node may determine a priority of UEs for resource allocation. For example, the network node may allocate network resources based at least in part on the time of receipt of the indication that the WUS is deferred from different UEs. In this way, the network node may prioritize data that has been buffered for the longest amount of time. In some aspects, the network node may prioritize data based at least in part on the indication of priority in the indication that the WUS is deferred.

[0113] As indicated by reference numeral 575, the UE may receive, and the network node may send, a resource allocation for sending data. In some aspects, the allocation may have a priority based at least in part on the WUS and / or an indication that the WUS is deferred, among other things.

[0114] Based at least in part on the UE deferring sending of the WUS, the network node may avoid waking up unnecessarily, may wake up for communication with more UEs for efficient use of wake-up time, and / or may conserve energy resources of the network node.

[0115] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0116] Figure 6 6 is a diagram of an example 600 associated with wake-up signaling of a network node sleep mode according to the present disclosure. Figure 6 As shown, a network node (e.g., network node 110, CU, DU, and / or RU) may communicate with a UE (e.g., UE 120). In some aspects, the network node and the UE may be part of a wireless network (e.g., wireless network 100). The UE and the network node may be in a Figure 6 The operations shown are preceded by the establishment of a communication link 605 .

[0117] like Figure 6 As shown, the network node can save energy by entering sleep mode 610 when not receiving traffic. However, in order to maintain awareness of whether one or more linked UEs need to enter a connected state or perform SDT, the network node can configure WUS timing. During the WUS, the network node wakes up to monitor WUS from one or more linked UEs.

[0118] like Figure 6 As shown, the network node does not receive a receive WUS during the WUS opportunity 615. The network node does not receive a WUS during the WUS opportunity 615 based at least in part on the first UE suppressing the sending of the deferred WUS 620 and the third UE suppressing the sending of the deferred WUS 625 during the WUS opportunity 615. The first UE and the third UE may be configured to postpone the sending of the WUS based at least in part on one or more conditions (such as the associated data having a latency parameter and / or a priority parameter that satisfies a threshold). For example, the first UE and the third UE may have data to send, and the data may have a relaxed latency requirement that allows the first UE and the third UE to wait for the data to be sent. In some aspects, the network node may wake up for an activity interval that includes multiple WUS opportunities (e.g., the activity interval may include multiple WUS opportunities within a period with increased network node energy consumption indicated by reference numeral 615).

[0119] Based at least in part on not receiving a WUS during WUS opportunity 615, the network node returns to sleep mode 630 until a subsequent WUS opportunity 635. During WUS opportunity 635, the network node receives a WUS 640 from the second UE and remains in awake mode 645 until communication with the second UE is completed.

[0120] In some aspects, the network node may send a wake-up signal 650 to the first UE, the second UE, and / or the third UE to indicate that the network node is awake and available for communication. In some aspects, the network node may broadcast or multicast the wake-up signal 650.

[0121] Based at least in part on detecting that the network node is awake, the first UE may send SR 655 and the second UE may send SR 660 to request resources for data transmission associated with deferred WUS 620 and deferred WUS 625. SRs 655 and 660 may be considered deferred WUSs.

[0122] like Figure 6 As shown, based at least in part on the first UE and the third UE deferring the sending of the WUS, the network node can wake up a single wake-up mode 645 to communicate with all of the first UE, the second UE, and the third UE, rather than waking up two different wake-up modes (e.g., outside of the WUS opportunity). This can save power resources of the network node.

[0123] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0124] Figure 7is a diagram illustrating an example process 700 performed, for example, by a UE in accordance with the present disclosure.
