[0002] This patent application claims priority to U.S. non-provisional patent application No. 17 / 885,394, filed on August 10, 2022, entitled “LOW-POWER SYNCHRONIZATION SIGNALS AND WAKE UP SIGNALS” and assigned to the assignee of this application. The disclosure of the prior application is considered a part of this patent application and is incorporated by reference into this patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for sending and receiving low power synchronization signals and wake-up signals. 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, among other examples).

[0006] 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 improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) 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 to better integrate with other open standards, as well as supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. 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

[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 interpreted 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.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[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 RATs beyond 5G (e.g., 6G).

[0031] 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, 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), 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). As 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)).

[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. 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.

[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 the coverage area of ​​the network node 110 and / or the 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 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 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 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 in , 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.

[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, 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).

[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, and / 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 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.

[0039] 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, 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 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 in 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 operably coupled, communicatively coupled, electronically coupled, and / 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 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.

[0041] 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.

[0042] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., according to 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 FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). It should be understood that, 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. A similar naming problem sometimes occurs 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 (7.125 GHz to 24.25 GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore 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 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz) and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0044] Considering the above examples, unless otherwise explicitly stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise explicitly stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or 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, and / 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 communications manager 140. As described in greater detail elsewhere herein, the communications manager 140 may use a low power receiver of the UE 120 to detect a low power synchronization signal (LP-SS) associated with a first coverage area that is larger than a second coverage area associated with a legacy synchronization signal block (SSB), and may use the low power receiver to monitor a low power wake-up signal (LP-WUS) associated with a third coverage area based at least in part on the LP-SS that is larger than a fourth coverage area associated with the legacy wake-up signal (WUS). Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0046] In some aspects, a network entity (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may transmit an LP-SS associated with a first coverage area that is larger than a second coverage area associated with a legacy SSB, and may transmit an LP-WUS associated with the LP-SS that is associated with a third coverage area that is larger than a fourth coverage area associated with the legacy WUS. 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 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.

[0049] At the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a 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 (CQIs) 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., precoding) 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 further process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 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 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.

[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 and / or antennas 252a to 252r) may include or 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 coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[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, 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 11 ) any aspects of any of the methods described herein.

[0054] 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 execute the instructions described herein (e.g., reference 20). Figures 4 to 11 ) any aspects of any of the methods described herein.

[0055] 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 sending and receiving LP-SS and LP-WUS, 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 Figure 8 The process of 800 Fig. 9 900 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 that stores 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 the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 8 The process of 800 Fig. 9 The process 900 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.

[0056] In some aspects, a UE (e.g., UE 120 and / or Fig.10 The apparatus 1000 of the UE may include means for detecting LP-SS using a low power receiver of the UE, wherein the LP-SS is associated with a first coverage area that is larger than a second coverage area associated with a legacy SSB; and / or means for monitoring LP-WUS based at least in part on the LP-SS using the low power receiver, wherein the LP-WUS is associated with a third coverage area that is larger than a fourth coverage area associated with the legacy WUS. Means for the UE to perform operations described herein may include, for example, one or more of the following: communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0057] In some aspects, a network entity (e.g., network node 110 and / or Fig.11The apparatus 1100 may include means for transmitting an LP-SS, wherein the LP-SS is associated with a first coverage area, the first coverage area being larger than a second coverage area associated with a legacy SSB; and / or means for transmitting an LP-WUS associated with the LP-SS, wherein the LP-WUS is associated with a third coverage area, the third coverage area being larger than a fourth coverage area associated with the legacy WUS. In some aspects, means for a network entity to perform operations described herein may include, for example, one or more of the following: a communications manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0058] 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.

[0059] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0060] 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 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) 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).

[0061] 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.

[0062] 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.

[0063] 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 radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0064] 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 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, and the wireless interface may include a receiver, a transmitter, or a transceiver (such as an RF transceiver), which is configured to receive signals or send signals to one or more of the other units via a wireless transmission medium, or both.

[0065] 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.

[0066] 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 partition such as that 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 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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).

[0071] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0072] The UE can save power and processing resources by deactivating a receiver (e.g., an antenna and optionally including integrated electronics such as an amplifier, an analog-to-digital (ADC) converter, a digital-to-analog converter (DAC), and / or another similar electronic device) when the UE is not scheduled to transmit to or receive from the network. However, the UE typically still performs measurements (e.g., measurements of legacy SSBs) and performs radio resource management (RRM) based on the measurements. In addition, the UE typically monitors legacy WUS from the network to determine when the UE should re-establish an RRC connection with the network. These processes increase power and processing resource consumption at the UE.

[0073] Additionally, when moving between coverage areas associated with legacy SSB and legacy WUS, the UE may perform a cell selection process (also known as "cell reselection" when switching from a current serving cell to a new serving cell). Cell selection includes measurements, transmissions, and receptions, which all increase power and processing resource consumption at the UE.

[0074] Some techniques and apparatus described herein enable a network entity (e.g., a network node 110, such as RU 340 or a controller of RU 340, such as CU 310 and / or DU 330) to transmit LP-SS with a larger coverage area than legacy SSB. A UE (e.g., UE 120) can measure LP-SS using a low power receiver such that a primary receiver of UE 120 remains deactivated. Thus, power and processing resource consumption at UE 120 is reduced. Additionally, because LP-SS is associated with a larger coverage area, UE 120 can perform cell reselection less frequently. Thus, power and processing resource consumption at UE 120 is further reduced.

[0075] Similarly, some techniques and apparatuses described herein enable the network node 110 to transmit LP-WUS with a larger coverage area than the legacy WUS. The UE 120 can monitor the LP-WUS using a low-power receiver, so that the main receiver of the UE 120 remains deactivated. Therefore, the power and processing resource consumption at the UE 120 is reduced.

[0076] Figure 4 4 is a diagram illustrating an example 400 associated with a receiver in a UE (eg, UE 120) according to the present disclosure. Figure 4 As shown, example 400 includes a low-power receiver 401 and a main receiver 403. Receivers 401 and 403 may each include at least one antenna and one or more integrated electronic devices, such as an amplifier, an ADC converter, a DAC, and / or another similar electronic device. In some aspects, low-power receiver 401 and main receiver 403 may share one or more electronic devices (e.g., an amplifier, a filter, an integrated circuit (IC) configured for FFT or another similar type of operation and / or another type of IC). Low-power receiver 401 is associated with a lower voltage and / or a lower current than main receiver 403. Therefore, when using low-power receiver 401 instead of main receiver 403, low-power receiver 401 may be associated with a longer battery life of UE 120.

[0077] like Figure 4 As shown in FIG. 1 and by reference numeral 410, a UE 120 may use a low power receiver 401 to perform LP-SS measurements. The LP-SS may be an electromagnetic signal sent by a network (e.g., from a network node 110 that includes or at least controls the RU 340) and generated at least in part based on a sequence. For example, the network may generate the LP-SS using a Zadoff-Chu sequence, a sequence based on a waveform based on on-off keying (OOK) and / or frequency shift keying (FSK), or another type of sequence. Figure 5 As described, the LP-SS may be associated with a first coverage area that is larger than a second coverage area associated with the legacy SSB.

[0078] The UE 120 may measure the received power (e.g., RSRP) associated with the LP-SS. When the received power of the LP-SS in a current area (e.g., associated with a serving cell of the UE 120) or a neighboring area (e.g., an area associated with a neighboring cell (such as a cell neighboring the serving cell)) fails to meet the received power threshold, the UE 120 may activate the primary receiver 403. For example, the UE 120 may perform cell reselection with the primary receiver 403 based on the LP-SS being too weak in order to reestablish an RRC connection with the network. Similarly, when the low power receiver 401 fails to detect the LP-SS (e.g., in the current area or the neighboring area), the UE 120 may activate the primary receiver 403. For example, the UE 120 may perform cell reselection with the primary receiver 403 based on the LP-SS being undetectable in order to reestablish an RRC connection with the network. Therefore, the UE 120 reduces the chance of missing a WUS from the network, which would waste power and processing resources at the network and increase latency between the network and the UE 120.

[0079] Additionally or alternatively, UE 120 may determine that a distance between UE 120 and an edge of a first coverage area associated with the LP-SS satisfies a distance threshold. UE 120 may track a location of UE 120 (e.g., using measurements of a global navigation satellite system (GNSS) and / or LP-SS, etc.). Additionally, UE 120 may receive an indication of the first coverage area (e.g., in a configuration for the LP-SS, such as in conjunction with Figure 7 As described above, UE 120 may determine a distance between the location of UE 120 and an edge of the first coverage area. UE 120 may activate primary receiver 403 based at least in part on the distance satisfying a distance threshold. For example, UE 120 may perform cell reselection with primary receiver 403 based on UE 120 being located at the edge in order to reestablish an RRC connection with the network. Thus, UE 120 reduces the chance of missing a WUS from the network, which would waste power and processing resources at the network and increase latency between the network and UE 120.

[0080] On the other hand, when the UE 120 detects the LP-SS (and when the received power of the LP-SS satisfies the received power threshold), the UE 120 may use the low power receiver 401 to perform LP-WUS monitoring, as shown by reference numeral 420. The LP-WUS may be an electromagnetic signal sent by the network (e.g., from the network node 110 that includes or at least controls the RU 340) and encodes an identifier associated with the UE 120 (e.g., a UE ID or another type of identifier associated with the UE 120). As shown in conjunction with Figure 5As described, the LP-WUS may be associated with a third coverage area that is larger than a fourth coverage area associated with the legacy WUS.

[0081] When UE 120 does not detect the LP-WUS, UE 120 may keep primary receiver 403 deactivated and measure subsequent transmissions of the LP-SS using low power receiver 401. Thus, UE 120 continues to save power and processing resources.

[0082] like Figure 4 4 and further illustrated by reference numeral 430, when UE 120 detects LP-WUS, UE 120 may activate primary receiver 403 to perform one or more measurements of one or more legacy SSBs of the serving cell and / or one or more neighboring cells. Thus, the network may configure the UE to perform RRM based at least in part on the paging periodicity. Additionally, in some aspects, UE 120 may perform cell reselection based on one or more results of the RRM. Thus, UE 120 improves the quality and reliability of communications with the network.

[0083] As shown by reference numeral 440, UE 120 may also use primary receiver 403 to detect a legacy WUS from the network and / or receive (and decode) a legacy paging message from the network. For example, UE 120 may use primary receiver 403 to monitor paging occasions to receive (and decode) a physical downlink control channel (PDCCH) message (or another type of legacy paging message) that encodes an identifier associated with UE 120 (e.g., a UE ID or another type of identifier associated with UE 120). Thus, when the PDCCH message indicates that UE 120 is being paged, UE 120 may determine to reestablish an RRC connection with the network (e.g., via a random access channel (RACH) procedure) so that the network can send data to UE 120.

[0084] By using such as combining Figure 4 According to the described techniques, the UE 120 can use the low power receiver 401 to measure the LP-SS, so that the main receiver 403 of the UE 120 remains deactivated. Therefore, power and processing resources are saved at the UE 120. Additionally, the UE 120 can use the low power receiver 401 to monitor the LP-WUS, so that the main receiver 403 of the UE 120 remains deactivated. Therefore, power and processing resources are saved at the UE 120.

[0085] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0086] Figure 5 is a diagram illustrating an example 500 associated with a synchronization signal and a WUS coverage area according to the present disclosure. Figure 5 As shown, example 500 includes coverage areas 501 associated with legacy signals. For example, coverage area 501a may be associated with a first cell, coverage area 501b may be associated with a second cell, and coverage area 501c may be associated with a third cell. Although described in conjunction with three cells, other examples may include fewer cells (e.g., two cells or one cell) or additional cells (e.g., four cells, five cells, etc.).

[0087] Each coverage area may be associated with at least one corresponding legacy SSB. For example, coverage area 501a may be associated with one or more first SSBs transmitted in a first cell, coverage area 501b may be associated with one or more second SSBs transmitted in a second cell, and coverage area 501c may be associated with one or more third SSBs transmitted in a third cell. In example 500, each coverage area is also associated with at least one corresponding legacy WUS. For example, coverage area 501a may be associated with one or more first WUSs transmitted in a first cell, coverage area 501b may be associated with one or more second WUSs transmitted in a second cell, and coverage area 501c may be associated with one or more third WUSs transmitted in a third cell. Other examples may include different coverage areas for SSBs compared to WUSs. For example, for a first WUS, a first cell may use different transmit power, subcarrier spacing (SCS), and / or transmit beams, etc., compared to a first SSB. Therefore, the coverage area associated with the first WUS may be larger or smaller than the coverage area associated with the first SSB.

[0088] like Figure 5As further shown in , example 500 includes a coverage area 503 associated with LP-SS and LP-WUS. Coverage area 503 is larger than coverage area 501a, coverage area 501b, and coverage area 501c (and the union thereof). To achieve a larger coverage area 503, LP-SS (and LP-WUS) may be associated with a first frequency band that is lower (in frequency) than a second frequency band associated with legacy SSB (and legacy WUS). As used herein, "frequency band" refers to a set of frequencies spanning a bandwidth. Because lower frequency bands are less susceptible to interference and absorption due to lower penetration losses, the resulting coverage area 503 is larger than coverage area 501a, coverage area 501b, and coverage area 501c. For example, LP-SS (and LP-WUS) may be transmitted in the FR1 frequency band, and legacy SSB (and legacy WUS) may be transmitted in the FR2 frequency band. In another example, LP-SS (and LP-WUS) may be transmitted in a sub-1 GHz band, and legacy SSB (and legacy WUS) may be transmitted in a sub-6 GHz band (eg, above 1 GHz).

[0089] Additionally or alternatively, the LP-SS (and LP-WUS) may be associated with a first SCS that is smaller than a second SCS associated with a legacy SSB (and legacy WUS). Additionally or alternatively, the LP-SS (and LP-WUS) may be associated with a first cyclic prefix (CP) associated with the first SCS that is longer than a second CP associated with a second SCS associated with the legacy SSB (and legacy WUS). Because a smaller SCS results in an electromagnetic signal having a longer OFDM symbol duration, and because a longer CP is less susceptible to timing errors, the resulting coverage area 503 is larger than coverage area 501a, coverage area 501b, and coverage area 501c.

[0090] Additionally or alternatively, the LP-SS (and LP-WUS) may be associated with a first transmit power that is higher than a second transmit power associated with the legacy SSB (and legacy WUS) such that the resulting coverage area 503 is larger than coverage area 501a, coverage area 501b, and coverage area 501c. Additionally or alternatively, the LP-SS (and LP-WUS) may be associated with a first set of transmit beams, each of which is wider than each beam in a second set of transmit beams associated with the legacy SSB (and legacy WUS). For example, the LP-SS (and LP-WUS) may be transmitted using a single beam with continuous repetitions and / or using inter-cell interference coordination, and the legacy SSB (and legacy WUS) may be transmitted using multi-beam scanning within each cell. Therefore, coverage area 503 is larger than coverage area 501a, coverage area 501b, and coverage area 501c. Additionally, due to the lower frequency band, smaller SCS, longer CP and / or smaller number of beams associated with LP-SS (and LP-WUS) compared to legacy SSB (and legacy WUS), the low power receiver of UE 120 can be less complex and consume less power than the main receiver of UE 120.

[0091] Additionally or alternatively, the LP-SS (and LP-WUS) may be associated with a single frequency network (SFN) with a multi-cell joint scheduling mode. In other words, the network nodes of the first cell, the second cell, and the third cell may coordinate (e.g., over a wireless and / or wired backhaul connection) to simultaneously transmit the LP-SS (and LP-WUS) on the same frequency (or multiple frequencies). Thus, coverage area 503 is larger than coverage area 501a, coverage area 501b, and coverage area 501c. Thus, legacy SSB (and legacy WUS) may be associated with a single cell scheduling mode within a SFN area (or with a multi-frequency network including the same network node and / or at least one different network node).

[0092] Other examples may include different coverage areas for LP-SS compared to LP-WUS. For example, a cell may use different transmit power, SCS, and / or transmit beams for LP-WUS compared to LP-SS, etc. Thus, the coverage area associated with LP-SS may be larger or smaller than the coverage area associated with LP-WUS.

[0093] By using such as combining Figure 5 With the described techniques, UE 120 may perform cell reselection less frequently because LP-SS and LP-WUS are associated with a larger coverage area 503. Thus, UE 120 saves power and processing resources.

[0094] As indicated above, Figure 5are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0095] Figure 6 6 is a diagram illustrating an example 600 associated with transmitting and receiving LP-SS and LP-WUS according to the present disclosure. Figure 6 As shown in , example 600 includes LP-SS periodically transmitted by the network (e.g., via network node 110, such as RU 340 or a controller of RU 340, such as CU 310 and / or DU 330). In example 600, LP-SS instance 601a is separated in time from LP-SS instance 601b by LP-SS periodicity 603. Figure 6 As further shown in FIG. 1 , when the primary receiver of UE 120 is deactivated (e.g., as in conjunction with Figure 4 As described above, LP-SS instances 601a and 601b may be received (eg, by UE 120).

[0096] Example 600 also includes a LP-WUS 605 sent by the network whenever the network pages UE 120 (e.g., when a buffer associated with UE 120 has data to be delivered to UE 120). Figure 6 As further shown in FIG. 1 , when the primary receiver of UE 120 is disabled, LP-WUS 605 may be received by UE 120 (e.g., as combined with Figure 4 UE 120 may activate a primary receiver based at least in part on detecting LP-WUS 605.

[0097] In some aspects, the gap 607 may separate (in time) the end of the monitoring opportunity associated with the LP-WUS 605 from the activation of the primary receiver of the UE 120 (e.g., to monitor for legacy SSB). Thus, the UE 120 may activate and configure (e.g., in hardware and / or software) the primary receiver of the UE 120 prior to using the primary receiver. Figure 7As described, the network may configure a gap (in time) between the end of the monitoring opportunity associated with the LP-WUS 605 and the start of the transmission of the legacy SSB. Thus, the UE 120 is aware that the gap 607 should not be longer than the gap configured by the network. In some aspects, the gap is based at least in part on the first frequency band associated with the LP-WUS 605 (and / or LP-SS), the second frequency band associated with the legacy SSB, the first SCS associated with the LP-WUS 605 (and / or LP-SS), and / or the second SBS associated with the legacy SSB. For example, when the difference between the first SCS and the second SCS is large and / or when the difference between the first frequency band and the second frequency band is large, the network may configure a longer gap. A longer gap allows the UE 120 to configure the primary receiver more accurately, which improves the quality and reliability of communication between the network and the UE 120. Similarly, when the difference between the first SCS and the second SCS is smaller and / or when the difference between the first frequency band and the second frequency band is smaller, the network may configure a shorter gap. A shorter gap reduces the latency between the LP-WUS 605 and the UE 120 receiving data from the network. Additionally or alternatively, the gap may be based at least in part on a device type (e.g., a brand, model, and / or 3GPP version associated with the UE 120), a type of low power receiver (e.g., brand or model), and / or a type of primary receiver (e.g., brand or model). For example, when the UE 120 is associated with a lower complexity, the gap may be longer so that the UE 120 uses more time for RF retuning.

[0098] The LP-WUS 605 may be quasi co-located (QCL) with the LP-SS. For example, the LP-WUS 605 may be associated with a transmit configuration indicator (TCI) state indicating that the LP-SS is a resource reference signal. Thus, the UE 120 may monitor the LP-WUS 605 without activating the primary receiver of the UE 120 (because the low power receiver of the UE 120 may measure the LP-SS, such as in conjunction with Figure 4 described).

[0099] like Figure 6As further shown in , UE 120 may activate the primary receiver for a certain amount of time. The amount of time may be preconfigured according to a 3GPP specification and / or another standard (e.g., stored in a memory of UE 120 and / or otherwise programmed into UE 120). Additionally or alternatively, UE 120 may use a timer value indicated by the network and associated with the activation of the primary receiver of UE 120. In a combined example, the network may select a timer value from a plurality of possible timer values ​​preconfigured according to a 3GPP specification and / or another standard (e.g., stored in a memory of UE 120 and / or otherwise programmed into UE 120). When UE 120 is associated with a data traffic level that meets a traffic threshold, the network may use a longer timer value. A longer timer value allows the network to perform more accurate RRM because UE 120 performs more legacy SSB measurements, which increases the quality and reliability of communications with UE 120. When UE 120 is associated with a data traffic level that fails to meet a traffic threshold, the network may use a shorter timer value. A shorter timer value saves power and processing resources at the UE 120. Additionally or alternatively, the timer value may be based at least in part on a device type (e.g., a brand, model, and / or 3GPP version associated with the UE 120), a type of low power receiver (e.g., brand or model), and / or a type of primary receiver (e.g., brand or model). For example, when the UE 120 is associated with a lower complexity, the timer value may be longer so that the UE 120 uses more time for synchronization and system information block (SIB) detection.

[0100] like Figure 6 As further shown in , when the primary receiver of UE 120 is activated, UE 120 may measure legacy SSB instances (e.g., SSB instances 609a, 609b, 609c, and 609d). Thus, UE 120 may perform measurements based on legacy SSB instances for RRM. Legacy SSB may be associated with a periodicity 611 that is shorter than a periodicity 603 associated with LP-SS. Thus, whenever UE 120 measures LP-SS instead of legacy SSB, UE 120 saves power and processing resources because LP-SS is less frequent in time.

[0101] Additionally, when the primary receiver of UE 120 is activated, UE 120 may monitor for legacy WUS and / or legacy paging messages 613. Thus, UE 120 may determine when to re-establish an RRC connection with the network in order to receive data intended for UE 120.

[0102] By using such as combining Figure 6According to the described technique, UE 120 uses a low power receiver to measure LP-SS instances 601a and 601b, so that the primary receiver of UE 120 remains deactivated. Therefore, power and processing resource consumption at UE 120 is reduced. Similarly, UE 120 can use a low power receiver to monitor LP-WUS 605, so that the primary receiver of UE 120 remains deactivated. Therefore, power and processing resource consumption at UE 120 is reduced.

[0103] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0104] Figure 7 is a diagram illustrating an example 700 associated with configuring LP-SS and LP-WUS according to the present disclosure. Figure 7 As shown in FIG. 1 , one or more network nodes 110 and UE 120 may (e.g., on a wireless network, such as Figure 1 communicate with each other on a wireless network 100).

[0105] As indicated by reference numeral 705, UE 120 may send a capability message and network node 110 may receive (e.g., directly or via RU 340) the capability message. The capability message may include a UECapabilityInformation data structure, as defined by a 3GPP specification and / or another standard. UE 120 may send a capability message, such as a UECapabilityEnquiry data structure, as defined by a 3GPP specification and / or another standard, in response to a capability inquiry message from network node 110.

[0106] The capability message may indicate that the UE 120 is configured to receive LP-SS. For example, the UE 120 may indicate that the UE 120 has a low power receiver for measuring the LP-SS, rather than using the primary receiver to measure the legacy SSB. Additionally, in some aspects, the capability message may include an indication of a recommended gap (in time) between the end of a monitoring opportunity associated with the LP-WUS and the start of transmission of the legacy SSB. For example, the UE 120 may indicate an amount of time (e.g., a minimum amount of time) that the UE 120 will use to activate and configure the primary receiver when the low power receiver detects the LP-WUS.

[0107] As indicated by reference numeral 710, the network node 110 may transmit (e.g., directly or via the RU 340) a configuration associated with the LP-SS, and the UE 120 may receive the configuration. The configuration may indicate that the LP-SS is to be transmitted (e.g., in response to a capability message indicating that the UE 120 is configured to receive the LP-SS). The configuration may also indicate a list of neighboring areas (e.g., cell IDs) in which the LP-SS is to be transmitted. Thus, the UE 120 may determine when the UE 120 is near an edge of a coverage area associated with the LP-SS (e.g., as described in conjunction with FIG. 1 ). Figure 4 Additionally or alternatively, the configuration may indicate a virtual cell ID associated with the LP-SS. For example, the virtual cell ID may be associated with multiple cells (and thus multiple cell IDs). The virtual cell ID may be used to generate the LP-SS (which may be a sequence-based electromagnetic signal).

[0108] Additionally or alternatively, the configuration may indicate a frequency band, a periodicity (and / or other time resource indication), one or more frequencies and / or parameter sets (e.g., SCS), etc. associated with the LP-SS. The configuration may also indicate a CP associated with the LP-SS, which may be longer than a CP associated with the legacy SSB. Thus, the UE 120 may use the configuration to monitor and detect the LP-SS. The configuration may also indicate a gap (in time) between the end of a monitoring opportunity associated with the LP-WUS and the activation of the primary receiver of the UE 120. Thus, when the LP-WUS is detected, the UE 120 will activate and configure the primary receiver within the gap (e.g., as in conjunction with Figure 4 The configuration may indicate a timer value for which the primary receiver should remain active (e.g., as described in conjunction with Figure 6 described).

[0109] As indicated by reference numeral 715, the network node 110 may transmit (e.g., directly or via the RU 340) a configuration associated with the LP-WUS, and the UE 120 may receive the configuration. In some aspects, the configuration may indicate that the LP-WUS is to be transmitted. The configuration may also indicate a list of neighboring areas (e.g., cell IDs) in which the LP-WUS is to be transmitted (e.g., when different from the list of neighboring areas in which the LP-SS is to be transmitted). Additionally or alternatively, the configuration may indicate a virtual cell ID associated with the LP-WUS (e.g., when different from the virtual cell ID associated with the LP-WUS).

[0110] Additionally or alternatively, the configuration may indicate a frequency band, a periodicity (and / or other time resource indication), one or more frequencies, and / or parameter sets (e.g., SCS), etc. associated with the LP-WUS. The configuration may also indicate a CP associated with the LP-WUS, which may be longer than a CP associated with the legacy WUS. The configuration for the LP-WUS may simply indicate a resource allocation that is different from the resource allocation for the LP-SS. The configuration may indicate a gap (in time) between the end of a monitoring opportunity associated with the LP-WUS and the activation of the primary receiver of the UE 120, and / or may indicate a timer value for which the primary receiver should remain activated (e.g., as combined with Figure 6 described).

[0111] In some aspects, LP-SS and LP-WUS can be multiplexed with legacy SSB and legacy WUS, respectively. For example, LP-SS and LP-WUS can be time-multiplexed with legacy SSB and legacy WUS, such as Figure 6 Alternatively, LP-SS and LP-WUS may be frequency multiplexed with legacy SSB and legacy WUS.

[0112] Thus, when UE 120 enters idle mode, as indicated by reference numeral 720, UE 120 may use a low power receiver instead of a primary receiver (e.g., as in conjunction with Figure 4 As described above, the UE 120 may measure the LP-SS from the network node 110, as indicated by reference numeral 725. Additionally, the UE 120 may monitor the LP-WUS from the network node 110, as indicated by reference numeral 730.

[0113] By using such as combining Figure 7 According to the described techniques, UE 120 can use a low power receiver to measure LP-SS, so that the primary receiver of UE 120 remains deactivated. Therefore, power and processing resources are saved at UE 120. Similarly, UE 120 can use a low power receiver to monitor LP-WUS, so that the primary receiver of UE 120 remains deactivated. Therefore, power and processing resources are saved at UE 120.

[0114] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.

[0115] Figure 8 800 is a diagram illustrating an example process 800 performed, for example, by a UE according to the present disclosure. Example process 800 is a UE (e.g., UE 120 and / or Fig.10 An example of an apparatus 1000) performing operations associated with receiving an LP-SS and an LP-WUS.

[0116] like Figure 8 As shown in FIG. 8 , in some aspects, process 800 may include using a low power receiver of a UE to detect an LP-SS associated with a first coverage area that is larger than a second coverage area associated with a legacy SSB (block 810). For example, a UE (e.g., using Fig.10 The communication manager 140 and / or detection component 1008 depicted in the UE can use a low power receiver of the UE to detect an LP-SS associated with a first coverage area that is larger than a second coverage area associated with a legacy SSB, as described herein.

[0117] like Figure 8 As further shown in FIG. 8 , in some aspects, process 800 may include monitoring, using a low power receiver based at least in part on the LP-SS, a LP-WUS associated with a third coverage area that is larger than a fourth coverage area associated with the legacy WUS (block 820). Fig.10 The communication manager 140 and / or monitoring component 1010 depicted in the figure can use a low power receiver to monitor the LP-WUS associated with a third coverage area based at least in part on the LP-SS, the third coverage area being larger than the fourth coverage area associated with the legacy WUS, as described herein.

[0118] Process 800 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0119] In a first aspect, the LP-SS and the LP-WUS are associated with a first frequency band that is lower than a second frequency band associated with the legacy SSB and the legacy WUS.

[0120] In a second aspect, alone or in combination with the first aspect, the LP-SS and the LP-WUS are associated with a SFN having a multi-cell joint scheduling mode, and the legacy SSB and the legacy WUS are associated with a single-cell scheduling mode.

[0121] In a third aspect, alone or in combination with one or more of the first and second aspects, the LP-SS and the LP-WUS are associated with a first number of transmit beams, which is less than a second number of transmit beams associated with the legacy SSB and the legacy WUS.

[0125] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, process 800 includes: determining (e.g., using the communication manager 140 and / or the determination component 1016) that the received power of the LP-SS in the current area or the neighboring area fails to meet the received power threshold; and activating the primary receiver of the UE (e.g., using the communication manager 140 and / or the activation component 1012) based at least in part on determining that the received power of the LP-SS fails to meet the received power threshold.

[0126] In an eighth aspect, either alone or in combination with one or more of the first to seventh aspects, process 800 includes: failing to detect the LP-SS in a current area or a neighboring area (e.g., using the communication manager 140 and / or the detection component 1008); and activating a primary receiver of the UE based at least in part on failing to detect the LP-SS (e.g., using the communication manager 140 and / or the activation component 1012).

[0127] In a ninth aspect, either alone or in combination with one or more of the first to eighth aspects, an end of a monitoring opportunity associated with the LP-WUS and activation of a primary receiver of the UE to monitor the legacy SSB are separated in time by a gap.

[0134] In a sixteenth aspect, alone or in combination with one or more of the first to fifteenth aspects, the LP-SS and the LP-WUS are associated with the same frequency band as the legacy SSB and the legacy WUS.

[0135] In a seventeenth aspect, alone or in combination with one or more of the first to sixteenth aspects, the LP-SS and the LP-WUS are multiplexed with the legacy SSB and the legacy WUS.

[0143] In a twenty-fifth aspect, alone or in combination with one or more of the first to twenty-fourth aspects, process 800 includes receiving (eg, using communication manager 140 and / or receiving component 1002) a configuration associated with the LP-WUS from a network node.

[0144] In a twenty-sixth aspect, either alone or in combination with one or more of aspects one to twenty-fifth, process 800 includes receiving (e.g., using communication manager 140 and / or receiving component 1002) from a network node a timer value associated with activation of a primary receiver of the UE.

[0145] although Figure 8An example block diagram of process 800 is shown, but in some aspects, process 800 may include Figure 8 Additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in the process 800. Additionally or alternatively, two or more of the blocks in the process 800 may be performed in parallel.

[0146] Fig. 9 900 is a diagram illustrating an example process 900 performed, for example, by a network entity according to the present disclosure. The example process 900 is a diagram in which a network entity (e.g., network node 110 and / or Fig.11 An example of an apparatus 1100) performing operations associated with sending an LP-SS and an LP-WUS.

[0147] like Fig. 9 As shown in , in some aspects, process 900 may include: sending an LP-SS associated with a first coverage area that is larger than a second coverage area associated with a legacy SSB (block 910). For example, a network entity (e.g., using Fig.11 The communications manager 150 and / or transmitting component 1104 depicted in FIG. 1 may transmit an LP-SS associated with a first coverage area that is larger than a second coverage area associated with a legacy SSB, as described herein.

[0148] like Fig. 9 As further shown in FIG. 9 , in some aspects, process 900 may include sending an LP-WUS associated with the LP-SS, the LP-WUS associated with a third coverage area, the third coverage area being larger than a fourth coverage area associated with the legacy WUS (block 920). For example, the network entity (e.g., using communication manager 150 and / or transmitting component 1104) may send an LP-WUS associated with the LP-SS, the LP-WUS associated with a third coverage area, the third coverage area being larger than a fourth coverage area associated with the legacy WUS, as described herein.
