ALLOCATING CODEPOINTS FOR USER EQUIPMENT SUBGROUPS IN LOW POWER WAKEUP SIGNAL MONITORING OCCASIONSFIELD OF THE DISCLOSURE
[0001] Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods associated with allocating codepoints for user equipment subgroups in low power wakeup signal monitoring occasions. DESCRIPTION OF THE RELATED TECHNOLOGY
[0002] Wireless communication systems are widely deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, or other traffic. Typical wireless communication systems may employ multiple-access radio access technologies (RATs) capable of supporting communication among multiple wireless communication devices including user devices or other devices by sharing the available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, or device transmit power, among other examples) . Such multiple-access RATs are supported by technological advancements that have been adopted in various telecommunication standards, which define common protocols that enable different wireless communication devices to communicate on a local, municipal, national, regional, or global level. An example telecommunication standard is New Radio (NR) . NR, which also may be referred to as 5G, is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) . As the demand for connectivity continues to increase, further improvements in NR may be implemented, and other RATs, such as 6G and beyond, may be introduced to enable new applications and facilitate new use cases.SUMMARY

[0021] In a wireless network, a UE may support a low power wakeup signal (LP-WUS) , which may serve to save user equipment (UE) battery power. The UE may employ a separate hardware with a simpler architecture and a lower operation power, as compared to traditional hardware, to receive the LP-WUS. The LP-WUS may trigger the UE to monitor a downlink control channel signal. The LP-WUS may be designed for low UE operational power. A network node may transmit the LP-WUS to wake up a UE for downlink control channel monitoring. A legacy downlink control channel monitoring may be replaced by an LP-WUS triggered downlink control channel monitoring.
[0022] An LP-WUS occasion (LO) may be defined for LP-WUS monitoring. The LO may be similar to a paging occasion (PO) . A periodicity of the LO may be the same as the UE’s inactive / idle mode DRX (iDRX) cycle. Different UEs may be associated with different periodicities of the LO. Multiple LP-WUS monitoring occasions (MOs) (e.g., 4 LP-WUS MOs) may be configured for the LO when multiple UE subgroups are to be paged in one iDRX cycle. At most one LP-WUS may be transmitted in an LP-WUS MO. Different LP-WUSs may be transmitted in different LP-WUS MOs of the LO. In one example, the LO may be associated with a UE radio resource control (RRC) idle / inactive mode, as well as an RRC connected mode.
[0023] A number of codepoints per MO that are able to be indicated by an LP-WUS may be independent of a number of UE subgroups per PO. The number of codepoints that are able to be indicated by the LP-WUS per MO may be related to a detection performance of the LP-WUS. For example, a longer LP-WUS may correspond to a lower false alarm rate from noise and more codepoints per MO. The number of UE subgroups per PO may be related to a false paging rate for a UE. A false paging may occur when the UE is indicated to wake up when the UE is not paged. A higher number of UE subgroups per PO may correspond to a lower false paging rate. The number of codepoints that are able to be indicated by the LP-WUS per MO and the number of UE subgroups per PO may not be integer multiples of each other. For example, the number of codepoints that are able to be indicated by the LP-WUS per MO may be equal to 16, and the number of UE subgroups per PO may be equal to 6. In some cases, when an integer multiple relationship is present, a total number of codepoints including a common codepoint in one LO may not be an integer multiple of the number of UE subgroups per PO.
[0024] As an example, the LP-WUS may provide 16 codepoints in one MO, and a number of UE subgroups per PO may be 8. In this example, a total number of codepoints per LP-WUS design for one LO associated with one PO is 1+8 = 9, and a total number of codepoints per LP-WUS design for one LO associated with two POs is 1+ (2×8) =17. An integer multiple relationship may not exist in either case.
[0025] Since the number of codepoints per MO that are able to be indicated by the LP-WUS may be independent of the number of UE subgroups per PO, and since the number of codepoints per MO may not be an integer multiple of the number of UE subgroups per PO, a codepoint allocation for UE subgroups in LP-WUS MOs may not be suitable. A number of codepoints needed for one LO may be greater than a number of codepoints provided by an LP-WUS in an MO, or a number of codepoints needed for one LO may be less than a number of codepoints provided by an LP-WUS in an MO, with respect to one or more POs. A lack of available codepoints or an excess of available codepoints associated with the LP-WUS may result in a poor utilization of resources, which may degrade an overall system performance.
[0026] Various aspects relate generally to LP-WUSs. Some aspects more specifically relate to allocating codepoints for UE subgroups in LP-WUS MOs. In some examples, a UE and / or a network node may identify an allocation of one or more codepoints associated with an LP-WUS in one or more MOs associated with an LO to one or more UE subgroups of one or more POs. The UE may identify the allocation based at least in part on signaling from the network node. Alternatively, the UE may identify the allocation based at least in part on a standard predefinition. The allocation may define a mapping of the one or more codepoints associated with the LP-WUS to the one or more UE subgroup groups. The allocation may define a common codepoint and one or more UE subgroup specific codepoints in an MO of the one or more MOs. Each MO in the one or more MOs may be associated with the common codepoint and / or the one or more UE subgroup specific codepoints. A plurality of codepoints (e.g., all codepoints) represented by the LP-WUS may be associated sequentially for the common codepoint and the one or more UE subgroup specific codepoints in accordance with the allocation. The UE and / or the network node may be able to allocate codepoints represented by the LP-WUS in each MO to UE subgroups of the one or more POs, such that both the common codepoint and the UE subgroup specific codepoints may be allocated in the MO, and each UE subgroup may statistically have an equal opportunity to be paged.
[0027] In some aspects, the network node may configure the UE with one or more LP-WUS parameters, which may include one or more codepoint assigned to the UE. The one or more codepoints may include the common codepoint and / or a UE subgroup specific codepoint. The UE subgroup specific codepoint may be for a UE subgroup in which the UE belongs. The network may configure the one or more LP-WUS parameters via RRC signaling. After a period of time, the UE may enter a low power mode. The UE, when in the low power mode, may listen for LP-WUS transmissions, instead of checking a downlink control channel. The network node may transmit an LP-WUS in a designated downlink slot. The LP-WUS may contain a specific codepoint to indicate which UE or which UE subgroup is to wake up. A codepoint may be a unique pattern or sequence in the LP-WUS that is preconfigured between the UE and the network node. The codepoint may allow the UE to differentiate whether the LP-WUS is intended for the UE or whether the LP-WUS is intended for other UEs. The UE, when operating in the low power mode, may receive the LP-WUS. The UE may check whether the one or more codepoints indicated in the LP-WUS matches with a preconfigured codepoint for the UE. When the one or more codepoints indicated in the LP-WUS matches with the preconfigured codepoint, the UE may wake up and start decoding the downlink control channel. Otherwise, the UE may remain in the low power mode.
[0028] In some aspects, the LP-WUS may be capable of transmitting a predefined number of codepoints. For example, the LP-WUS may be capable of transmitting 16 codepoints. The LP-WUS may include the common codepoint and / or the UE subgroup specific codepoints. The common codepoint may be common for a plurality of UEs. The common codepoint may correspond to a plurality of UE subgroups. When the UE receives the LP-WUS with the common codepoint, the UE may determine whether the UE is part of any of the plurality of UE subgroups. When the UE is part of any of the plurality of UE subgroups, the UE may wake up to monitor the downlink control channel. When the UE is not part of any of the plurality of UE subgroups, the UE may not wake up to monitor the downlink control channel. A UE subgroup specific codepoint may apply to a set of UEs that are associated with a given UE subgroup. For example, the UE subgroup specific codepoint may be applicable for a UE subgroup of 10 UEs. When the UE receives the LP-WUS with the UE subgroup specific codepoint, the UE may determine whether the UE is part of a UE subgroup associated with the UE subgroup specific codepoint. When the UE is part of that UE subgroup, the UE may wake up to monitor the downlink control channel. When the UE is not part of that UE subgroup, the UE may not wake up to monitor the downlink control channel.
[0029] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by defining the allocation of codepoints, the described techniques can be used by the UE and / or the network node to identify the allocation and receive / transmit the LP-WUS based at least in part on the allocation. The allocation may define a mapping of codepoints, which may be helpful because a number of codepoints per MO may be independent of a number of UE subgroups per PO. The allocation may define the mapping of codepoints when the number of codepoints per MO is not an integer multiple of the number of UE subgroups per PO. The allocation may define an ordering of different codepoints for different UE subgroups in different POs, when the plurality of codepoints represented by the LP-WUS are mapped to the one or more UE subgroups. A proper allocation of the codepoints represented by the LP-WUS may optimize a utilization of resources (e.g., LP-WUS codepoint resources) when indicating different UE subgroups, thereby improving an overall system performance.
[0030] 5G New Radio (NR) may support enhanced mobile broadband (eMBB) access, Internet of Things (IoT) networks or reduced capability (RedCap) device deployments, ultra-reliable low-latency communication (URLLC) applications, or massive machine-type communication (mMTC) , among other examples. To support these and other target verticals, a wireless communication system may be designed to implement a modularized functional infrastructure, a disaggregated and service-based network architecture, network function virtualization, network slicing, multi-access edge computing, millimeter wave (mmWave) technologies including massive multiple-input multiple-output (MIMO) , beamforming, IoT device or RedCap device connectivity and management, industrial connectivity, licensed and unlicensed spectrum access, sidelink and other device-to-device direct communication (for example, cellular vehicle-to-everything (CV2X) communication) , frequency spectrum expansion, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, device aggregation, advanced duplex communication (for example, sub-band full-duplex (SBFD) ) , multiple-subscriber implementations, high-precision positioning, radio frequency (RF) sensing, network energy savings (NES) , low-power signaling and radios, or artificial intelligence or machine learning (AI / ML) , among other examples.
[0031] The foregoing and other technological improvements may support use cases, such as wireless fronthauls, wireless midhauls, wireless backhauls, wireless data centers, extended reality (XR) and metaverse applications, meta services for supporting vehicle connectivity, holographic and mixed reality communication, autonomous and collaborative robots, vehicle platooning and cooperative maneuvering, sensing networks, gesture monitoring, human-brain interfacing, digital twin applications, asset management, and universal coverage applications using non-terrestrial or aerial platforms, among other examples.
[0032] The methods, operations, apparatuses, and techniques described herein may enable one or more of the foregoing technologies or new technologies or support one or more of the foregoing use cases or new use cases.
[0033] Fig. 1 is a diagram illustrating an example of a wireless communication network 100. The wireless communication network 100 may be or may include elements of a 5G network or a 6G network, among other examples. The wireless communication network 100 may include multiple network nodes 110. For example, in Fig. 1, the wireless communication network 100 includes multiple network nodes 110, including a network node 110a and a network node 110b (each of which also may be referred to herein simply as a “network node 110” ) . The network nodes 110 may support communications with multiple UEs 120. For example, in Fig. 1, the network nodes 110 support communication with a UE 120a, a UE 120b, and a UE 120c (each of which also may be referred to herein simply as a “UE 120” ) . In some examples, a UE 120 also may communicate with other UEs 120 and a network node 110 also may communicate with a core network and with other network nodes 110.
[0034] The network nodes 110 and the UEs 120 of the wireless communication network 100 communicate using the electromagnetic spectrum, which may be subdivided into various licensed or unlicensed operating bands, frequency ranges, component carriers, or channels that define associated frequencies available for communications. In some examples, each of the network nodes 110 and the UEs 120 may communicate using one or multiple component carriers in one or more operating bands or ranges. Typically, various operating bands are defined as frequency range designations FR1 (410 MHz through 7.125 GHz) , FR2 (24.25 GHz through 52.6 GHz) , FR3 (7.125 GHz through 24.25 GHz) , FR4a or FR4-1 (52.6 GHz through 71 GHz) , FR4 (52.6 GHz through 114.25 GHz) , and FR5 (114.25 GHz through 300 GHz) . Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in some documents and articles. Similarly, FR2 is often referred to (interchangeably) as a “millimeter wave” band in some documents and articles.
[0035] A network node 110 or a UE 120 may include one or more devices, components, or systems that enable communication with other devices, components, or systems of the wireless communication network 100. For example, a UE 120 and a network node 110 may each include one or more chips, system-on-chips (SoCs) , chipsets, packages, or devices that individually or collectively constitute or comprise a processing system. As shown in Fig. 1, each UE 120 includes a processing system 140 and each network node 110 includes a processing system 145. A processing system (for example, the processing system 140 or the processing system 145) includes processor (or “processing” ) circuitry in the form of one or multiple processors, microprocessors, processing units (such as central processing units (CPUs) , graphics processing units (GPUs) , neural processing units (NPUs) (also referred to as neural network processors or deep learning processors (DLPs) ) , or digital signal processors (DSPs) ) , processing blocks, application-specific integrated circuits (ASICs) , programmable logic devices (PLDs) , or other discrete gate or transistor logic or circuitry (any one or more of which may be generally referred to herein individually as a “processor” or collectively as “the processor” or “the processor circuitry” ) . Such processors may be individually or collectively configurable or configured to perform various functions or operations described herein. A group of processors collectively configurable or configured to perform a set of functions may include a first processor configurable or configured to perform a first function of the set and a second processor configurable or configured to perform a second function of the set. In some other examples, each of a group of processors may be configurable or configured to perform a same set of functions.
[0036] The processing system 140 and the processing system 145 may each include memory circuitry in the form of one or multiple memory devices, memory blocks, memory elements, or other discrete gate or transistor logic or circuitry, each of which may include or implement tangible storage media, such as random-access memory, or read-only memory, or combinations thereof (any one or more of which may be generally referred to herein individually as a “memory” or collectively as “the memory” or “the memory circuitry” ) . One or more of the memories may be coupled (for example, operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) with one or more of the processors. One or more of the memories may individually or collectively store processor-executable code or instructions (such as software) (for example, which may be referred to as “one or more code-storing memories” or “code-storing memory circuitry” ) . For example, “code-storing memory” or “code-storing memory circuitry” refers to memory (or memory circuitry) that is configured to store processor-executable code or instructions. The processor-executable code or instructions, when executed by one or more of the processors, may configure one or more of the processors (or processing circuitry) to perform various functions or operations described herein. Additionally, or alternatively, in some examples, one or more of the processors may be configured to perform various functions or operations described herein without requiring configuration by software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, or functions, among other examples, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.
[0037] The processing system 140 and the processing system 145 may each include or be coupled with one or more modems (such as a cellular (for example, a 5G or 6G compliant) modem) . In some examples, one or more processors of the processing system 140 or the processing system 145 may include or implement one or more of the modems. The processing system 140 and the processing system 145 also may include or be coupled with multiple radios (collectively “the radio” ) , multiple RF chains, or multiple transceivers, each of which may in turn be coupled with one or more of multiple antennas. In some examples, one or more processors of the processing system 140 or the processing system 145 may include or implement one or more of the radios, RF chains, or transceivers. An RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs) , or other devices that convert between an analog signal (such as for transmission or reception via an air interface) and a digital signal (such as for processing by the processing system 140 or by the processing system 145) .
[0038] A network node 110 and a UE 120 may each include one or multiple antennas or antenna arrays. Typical network nodes 110 and UEs 120 may include multiple antennas, which may be organized or structured into one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. As used herein, the term “antenna” can refer to one or more antennas, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays. The term “antenna panel” can refer to a group of antennas (such as antenna elements) arranged in an array or panel, which may facilitate beamforming by manipulating parameters associated with the group of antennas. The term “antenna module” may refer to circuitry including one or more antennas as well as one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device, such as the network node 110 and the UE 120.
[0039] A network node 110 may be, may include, or also may be referred to as an NR network node, a 5G network node, a 6G network node, a Node B, a gNB, an access point (AP) , a transmission reception point (TRP) , a network entity, a network element, a network equipment, or another type of device, component, or system included in a radio access network (RAN) . In various deployments, a network node 110 may be implemented as a single physical node (for example, a single physical structure) or may be implemented as two or more physical nodes (for example, two or more distinct physical structures) . For example, a network node 110 may be a device or system that implements a part of a radio protocol stack, a device or system that implements a full radio protocol stack (such as a full gNB protocol stack) , or a collection of devices or systems that collectively implement the full radio protocol stack. For example, and as shown, a network node 110 may be an aggregated network node having an aggregated architecture, meaning that the network node 110 may implement a full radio protocol stack that is physically and logically integrated within a single physical structure in the wireless communication network 100. For example, an aggregated network node 110 may include a single standalone base station or a single TRP that operates with a full radio protocol stack to enable or facilitate communication between a UE 120 and a core network of the wireless communication network 100.
[0040] Alternatively, and as also shown, a network node 110 may be a disaggregated network node 110 (sometimes referred to as a disaggregated base station) , having a disaggregated architecture, meaning that the network node 110 may operate with a radio protocol stack that is physically distributed or logically distributed among two or more nodes in the same geographic location or in different geographic locations. In some deployments, disaggregated network nodes 110 may be used in an integrated access and backhaul (IAB) network, in an open radio access network (O-RAN) (such as a network configuration in compliance with the O-RAN Alliance) , or in a virtualized radio access network (vRAN) , also known as a cloud radio access network (C-RAN) , to facilitate scaling by separating network functionality into multiple units or modules that can be individually deployed.
[0041] The disaggregated network nodes 110 of the wireless communication network 100 may include one or more central units (CUs) , one or more distributed units (DUs) , and one or more radio units (RUs) . A CU may host one or more higher layers, such as an RRC layer, a packet data convergence protocol (PDCP) layer, and a service data adaptation protocol (SDAP) layer, among other examples. A DU may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, or one or more higher physical (PHY) layers depending, at least in part, on a functional split, such as a functional split defined by the 3GPP. In some examples, a DU also may host a lower PHY layer that is configured to perform functions, such as a fast Fourier transform (FFT) , an inverse FFT (IFFT) , beamforming, or physical random access channel (PRACH) extraction and filtering, among other examples. An RU may perform RF processing functions or lower PHY layer functions, such as an FFT, an IFFT, beamforming, or PRACH extraction and filtering, among other examples, according to a functional split, such as a lower layer split (LLS) . In such an architecture, each RU can be operated to handle over the air (OTA) communication with one or more UEs 120. In some examples, a single network node 110 may include a combination of one or more CUs, one or more DUs, or one or more RUs. In some examples, a CU, a DU, or an RU may be implemented as a virtual unit, such as a virtual central unit (VCU) , a virtual distributed unit (VDU) , or a virtual radio unit (VRU) , among other examples, which may be implemented as a virtual network function, such as in a cloud deployment.
[0042] In some examples, the wireless communication network 100 may be a heterogeneous network that includes network nodes 110 of various types. Different types of network nodes 110 may generally operate on the same or different operating bands, transmit at different power levels, or serve different coverage areas, each of which may be referred to as or associated with a particular cell 130 (for example, a cell 130a and a cell 130b) .
[0043] The UEs 120 may be physically dispersed throughout the coverage area of the wireless communication network 100, and each UE 120 may be stationary or mobile. A UE 120 may be, may include, or also may be referred to as an access terminal, a mobile station, a client device, or a subscriber unit. A UE 120 may be, include, or be coupled with a cellular phone (for example, 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, a camera, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (for example, a smart watch, smart clothing, smart glasses, a smart wristband, or smart jewelry) , a gaming device, an entertainment device (for example, a music device, a video device, or a satellite radio) , an XR device, a vehicular component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device) , an artificially intelligent robot or other device implementing artificial intelligence, a UE function of a network node, or any other suitable device or function that may communicate in the wireless communication network 100.
[0044] Some UEs 120 may be classified according to different categories in association with different complexities or different capabilities. UEs 120 in a first category may be associated with relatively low complexity or cost such as NB-IoT devices or eMTC UEs. UEs 120 in a second category may include higher complexity or cost devices, such as mission-critical IoT devices, baseline UEs, high-tier UEs, advanced UEs, full-capability UEs, or premium UEs that are capable of URLLC, eMBB, or precise positioning in the wireless communication network 100. A third category of UEs 120 may have mid-tier complexity or capabilities (for example, capabilities between that of the UEs 120 of the first category and the UEs 120 of the second category) . A UE 120 of the third category may be referred to as a reduced capability UE ( “RedCap UE” ) , a mid-tier UE, an NR-Light UE, or an NR-Lite UE, among other examples.
[0045] In some examples, a network node 110 may be, may include, or may operate as an RU, a TRP, or a base station that communicates with one or more UEs 120 via a radio access link (which may be referred to as a “Uu” link) . The radio access link may include a downlink and an uplink. “Downlink” (or “DL” ) refers to a communication direction from a network node 110 to a UE 120, and “uplink” (or “UL” ) refers to a communication direction from a UE 120 to a network node 110. Downlink and uplink resources may include time domain resources (for example, frames, subframes, slots, and symbols) , frequency domain resources (for example, frequency bands, component carriers (CCs) , subcarriers, resource blocks, and resource elements) , and spatial domain resources (for example, particular transmit directions or beams) .
[0046] Frequency domain resources may be subdivided into bandwidth parts (BWPs) . A BWP may be a block of frequency domain resources (for example, a continuous set of resource blocks (RBs) within a full component carrier bandwidth) that may be configured at a UE-specific level. A UE 120 may be configured with both an uplink BWP and a downlink BWP (which may be the same or different) . Each BWP may be associated with its own numerology (indicating a sub-carrier spacing (SCS) and cyclic prefix (CP) ) . A BWP may be dynamically configured or activated (for example, by a network node 110 transmitting a downlink control information (DCI) configuration to the one or more UEs 120) or reconfigured (for example, in real-time or near-real-time) according to changing network conditions in the wireless communication network 100 or specific requirements of one or more UEs 120. An active BWP defines the operating bandwidth of the UE 120 within the operating bandwidth of the serving cell.
[0047] As used herein, a downlink signal may be or include a reference signal, control information, or data. For example, downlink reference signals include a primary synchronization signal (PSS) , a secondary SS (SSS) , an SS block (SSB) (for example, that includes a PSS, an SSS, and a physical broadcast channel (PBCH) ) , a demodulation reference signal (DMRS) , a phase tracking reference signal (PTRS) , a tracking reference signal (TRS) , and a channel state information (CSI) reference signal (CSI-RS) , among other examples. A downlink signal carrying control information or data may be transmitted via a downlink channel. Downlink channels may include one or more control channels for transmitting control information and one or more data channels for transmitting data. Downlink reference signals may be transmitted in addition to, or multiplexed with, downlink control channel communications or downlink data channel communications. A downlink control channel may be specifically used to transmit DCI from a network node 110 to a UE 120. DCI generally contains the information the UE 120 needs to identify RBs in a subsequent subframe and how to decode them, including a modulation and coding scheme (MCS) or redundancy version parameters. Different DCI formats carry different information, such as scheduling information in the form of downlink or uplink grants, slot format indicators (SFIs) , preemption indicators (PIs) , transmit power control (TPC) commands, hybrid automatic repeat request (HARQ) information, new data indicators (NDIs) , among other examples. A downlink data channel may be used to transmit downlink data (for example, user data associated with a UE 120) from a network node 110 to a UE 120. Downlink control channels may include physical downlink control channels (PDCCHs) , and downlink data channels may include physical downlink shared channels (PDSCHs) . Control information or data communications may be transmitted on a PDCCH and PDSCH, respectively. For example, a PDCCH can carry DCI, while a PDSCH can carry a MAC control element (MAC-CE) , an RRC message, or user data, among other examples. Each PDSCH may carry one or more transport blocks (TBs) of data.
[0048] As used herein, an uplink signal may include a reference signal, control information, or data. For example, uplink reference signals include a sounding reference signal (SRS) , a PTRS, and a DMRS, among other examples. An uplink signal carrying control information or data may be transmitted via an uplink channel. An uplink channel may include one or more control channels for transmitting control information and one or more data channels for transmitting data. Uplink reference signals may be transmitted in addition to, or multiplexed with, uplink control channel communications or uplink data channel communications. An uplink control channel may be specifically used to transmit uplink control information (UCI) from a UE 120 to a network node 110. An uplink data channel may be used to transmit uplink data (for example, user data associated with a UE 120) from a UE 120 to a network node 110. Uplink control channels may include physical uplink control channels (PUCCHs) , and uplink data channels may include physical uplink shared channels (PUSCHs) . Control information or data communications may be transmitted on a PUCCH and PUSCH, respectively. For example, a PUCCH can carry UCI, while a PUSCH can carry a MAC-CE, an RRC message, or user data, among other examples. UCI can include a scheduling request (SR) , HARQ feedback information (for example, a HARQ acknowledgement (ACK) indication or a HARQ negative acknowledgement (NACK) indication) , uplink power control information (for example, an uplink TPC parameter) , or CSI, among other examples. CSI can include a channel quality indicator (CQI) (indicative of downlink channel conditions to facilitate selection of transmission parameters, such as an MCS, by a network node 110) , a precoding matrix indicator (PMI) , a CSI-RS resource indicator (CRI) (for example, indicative of a beam used to transmit a CSI-RS) , an SS / PBCH resource block indicator (SSBRI) (for example, indicative of a beam used to transmit an SSB) , a layer indicator (LI) , a rank indicator (RI) , or measurement information (for example, a layer 1 (L1) -reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, among other examples) which can be used for beam management, among other examples. Each PUSCH may carry one or more TBs of data.
[0049] The information (for example, data, control information, or reference signal information) transmitted by a network node 110 to a UE 120, or vice versa, may be represented as a sequence of binary bits that are mapped (for example, modulated) to an analog signal waveform (for example, a discrete Fourier transform (DFT) -spread-orthogonal frequency division multiplexing (OFDM) (DFT-s-OFDM) waveform or a CP-OFDM waveform) that is transmitted by the network node 110 or UE 120 over a wireless communication channel. In some examples, the network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively) may select an MCS (for example, an order of quadrature amplitude modulation (QAM) , such as 64-QAM, 128-QAM, or 256-QAM, among other examples) for a downlink signal or an uplink signal. For example, the network node 110 may select an MCS for a downlink signal in accordance with UCI received from the UE 120 or may transmit, to the UE 120, an indication of an MCS to be applied for an uplink signal.
[0050] A network node 110 or a UE 120 (such as by using the processing system 145 or the processing system 140, respectively, or one or more coupled modems) may perform signal processing on the information (such as filtering, amplification, modulation, digital-to-analog conversion, an IFFT operation, multiplexing, interleaving, mapping, or encoding, among other examples) to generate a processed signal in accordance with the selected MCS. In some examples, the network node 110 or the UE 120 (for example, using the processing system 145 or the processing system 140, respectively, or one or more coupled encoders or modems) may perform a channel coding operation or a forward error correction (FEC) operation to control errors in transmitted information. For example, the network node 110 or the UE 120 may perform an encoding operation to generate encoded information (such as by selectively introducing redundancy into the information, typically using an error correction code (ECC) , such as a polar code or a low-density parity-check (LDPC) code) . The network node 110 or the UE 120 (for example, using the processing system 145 or one or more modems) may further perform spatial processing (for example, precoding) on the encoded information to generate one or more processed or precoded signals for downlink or uplink transmission, respectively. In some examples, the network node 110a or the UE 120a may perform codebook-based precoding or non-codebook-based precoding. Codebook-based precoding may involve selecting a precoder (for example, a precoding matrix) using a codebook. For example, the network node 110a may provide precoding information indicating which precoder, defined by the codebook, is to be used by the UE 120a. Non-codebook-based precoding may involve selecting or deriving a precoder based on, or otherwise associated with, one or more downlink or uplink signal measurements. The network node 110a or the UE 120a may transmit the processed downlink or uplink signals, respectively, via one or more antennas.
[0051] The network node 110a or the UE 120a may receive uplink signals or downlink signals, respectively, via one or more antennas. The network node 110a or the UE 120a (for example, using the processing system 145 or the processing system 140, respectively, or one or more coupled modems) may perform signal processing (for example, in accordance with the MCS) on the received uplink or downlink signals, respectively (such as filtering, amplification, demodulation, analog-to-digital conversion, an FFT operation, demultiplexing, deinterleaving, de-mapping, equalization, interference cancellation, or decoding, among other examples) , to map the received signal (s) to a sequence of binary bits (for example, received information) that estimates the information transmitted by the network node 110 or the UE 120 via the downlink or uplink signals. The network node 110a or the UE 120a (for example, using the processing system 145 or the processing system 140, respectively, or a coupled decoder or one or more modems) may decode the received information (such as by using an ECC, a decoding operation, or an FEC operation) to detect errors or correct bit errors in the received information to generate decoded information. The decoded information may estimate the information transmitted via the downlink or uplink signals.
[0052] In some examples, a UE 120 and a network node 110 may perform MIMO communication. MIMO communication generally refers to transmitting or receiving multiple signals (such as multiple layers or multiple data streams) simultaneously over the same time and frequency resources. A network node 110 or a UE 120 may communicate using single-user MIMO or multi-user MIMO (MU-MIMO) , the latter of which being used by a network node 110 to simultaneously transmit signals to multiple UEs 120. MIMO techniques may involve spatial multiplexing (multi-layer transmission) or beamforming. To implement beamforming, the amplitudes or phases of signals transmitted via antenna elements may be modulated and shifted relative to each other (such as by manipulating a phase shift, a phase offset, or an amplitude) to generate one or more beams. For example, a network node 110 may generate one or more beams 160a, and a UE 120 may generate one or more beams 160b. The term “beam” may refer to a directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction, a directional reception of a wireless signal from a transmitting device or otherwise in a desired direction, a direction associated with such a directional transmission or directional reception, a set of directional resources associated with a signal transmission or signal reception (for example, an angle of arrival, a horizontal direction, or a vertical direction) , or a set of parameters or resources associated with one or more aspects of a directional signal, among other examples.
[0053] In some examples, a network node 110 or a UE 120 may implement massive MIMO, which may be associated with an increased (for example, “massive” ) quantity of antennas at the network node 110 or at the UE 120, such as in a network implementing mmWave technology, which enables more precise beamforming or reduced interference. In some examples, the wireless communication network 100 may implement multi-TRP (mTRP) operation (including redundant transmission or reception on multiple TRPs) or non-coherent joint transmission (NC-JT) .
[0054] The network node 110 and the UE 120 may establish a communication link or beam pair, and otherwise increase reliability, throughput, signal strength, or other signal properties for MIMO communications, by performing beam management operations, such as an initial beam acquisition operation, a beam refinement operation, or a beam recovery operation. For example, an initial beam acquisition operation may involve the network node 110 transmitting signals (for example, SSBs or other signals) via respective beams (for example, of the beams 160 of the network node 110) and the UE 120 receiving and measuring the signal (s) via respective beams of multiple beams (for example, from the beams 160 of the UE 120) to identify a best beam (or beam pair) for communication between the UE 120 and the network node 110. A beam refinement operation may involve a first device (for example, the UE 120 or the network node 110) transmitting signal (s) via a subset of beams (for example, identified based on, or otherwise associated with, measurements reported as part of one or more other beam management operations) . A second device (for example, the network node 110 or the UE 120) may receive the signal (s) via a single beam (for example, to identify the best beam for communication from the subset of beams) . The beam (s) may be identified or defined via one or more spatial parameters, such as a transmission configuration indicator (TCI) state or a quasi co-location (QCL) parameter, among other examples.
[0055] Some aspects and techniques as described herein may be implemented, at least in part, using an artificial intelligence (AI) program (for example, referred to herein as an “AI / ML model” ) , such as a program that includes a machine learning (ML) model or an artificial neural network (ANN) model. The AI / ML model may be deployed at one or more devices 165 (for example, one or more network nodes 110, one or more UEs 120, one or more servers, or one or more components of a cloud computing network, among other examples) . For example, in a deployment in which AI / ML functionality is performed independently at a device 165, sometimes referred to as “overlay AI / ML, ” the AI / ML model (or an instance or portion of the AI / ML model) may be deployed at a UE 120 (for example, by the processing system 140) , a network node 110 (for example, by the processing system 145) , one or more servers, or one or more components of a cloud computing network, among other examples. Additionally, or alternatively, in a deployment where AI / ML functionality is coordinated between different devices 165, sometimes referred to as “coordinated AI / ML, ” or performed at all device and network layers, sometimes referred to as “native AI / ML, ” the AI / ML model (or an instance of the AI / ML model) may be deployed at multiple devices 165 (for example, a first portion of the AI / ML model may be deployed at a UE 120 and a second portion of the AI / ML model may be deployed at a network node 110) . In other examples of coordinated AI / ML or native AI / ML, a first AI / ML model may be deployed at a UE 120 and a second AI / ML model may be deployed at a network node 110. The AI / ML model (s) may be configured to enhance various aspects of the wireless communication network 100 (for example, to increase privacy, reliability, or efficient use of network bandwidth, or to reduce latency, among other examples) . For example, the AI / ML model (s) may be trained to identify patterns or relationships in data corresponding to the wireless communication network 100, a device, or an air interface, among other examples. The AI / ML model (s) may support operational decisions relating to one or more aspects associated with wireless communications devices, networks, or services.
[0056] Accordingly, in some examples, the AI / ML model (s) may enable AI-as-a-Service (for example, an end-to-end AI / ML service via a user plane) for use cases, such as a self-organizing network (SON) , minimization of drive test (MDT) , quality of experience (QoE) , positioning, sensing, predictive mobility, or traffic prediction, among other examples. In some examples, AI-as-a-Service use cases may include measurement collection reporting by a UE 120, device selection criteria (for example, according to a geographical area where measurements are to be collected or UE capabilities to be used to collected measurements) , or reporting configurations (for example, reporting parameters such as location, time, or sensor information, among other examples) . Additionally, or alternatively, the AI / ML model (s) may enable AI / ML procedures (for example, RAN-triggered service establishment, configuration, inferencing using UE-side or network-side models, performance monitoring or management, or capability signaling, among other examples) . Additionally, or alternatively, the AI / ML model (s) may enable RAN-based AI / ML services via one or more application program interfaces (APIs) or management interfaces for use cases, such as beam management, radio resource monitoring (RRM) relaxation, mobility prediction, load prediction, network energy savings, or coverage and capacity improvements, among other examples.
[0057] In some aspects, the UE 120 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may identify an allocation of one or more codepoints associated with an LP-WUS in one or more MOs associated with an LO to one or more UE subgroups of one or more POs, wherein the allocation defines a common codepoint and one or more UE subgroup specific codepoints in an MO of the one or more MOs; and receive the LP-WUS based at least in part on the allocation. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0058] In some aspects, the network node 110 may include a communication manager 155. As described in more detail elsewhere herein, the communication manager 155 may identify an allocation of one or more codepoints associated with an LP-WUS in one or more MOs associated with an LO to one or more UE subgroups of one or more POs, wherein the allocation defines a common codepoint and one or more UE subgroup specific codepoints in an MO of the one or more MOs; and transmit the LP-WUS based at least in part on the allocation. Additionally, or alternatively, the communication manager 155 may perform one or more other operations described herein.
[0059] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.
[0060] Fig. 2 is a diagram illustrating an example disaggregated network node architecture 200. One or more components of the example disaggregated network node architecture 200 may be, may include, or may be included in one or more network nodes (such one or more network nodes 110) . The disaggregated network node architecture 200 may include a CU 210 that can communicate directly with a core network 220 via a backhaul link, or that can communicate indirectly with the core network 220 via one or more disaggregated control units, such as a non-real-time (Non-RT) RAN intelligent controller (RIC) 250 associated with a Service Management and Orchestration (SMO) Framework 260 or a near-real-time (Near-RT) RIC 270 (for example, via an E2 link) . The CU 210 may communicate with one or more DUs 230 via respective midhaul links, such as via F1 interfaces. Each of the DUs 230 may communicate with one or more RUs 240 via respective fronthaul links. Each of the RUs 240 may communicate with one or more UEs 120 via respective RF access links. In some deployments, a UE 120 may be simultaneously served by multiple RUs 240.
[0061] Each of the components of the disaggregated network node architecture 200, including the CUs 210, the DUs 230, the RUs 240, the Near-RT RICs 270, the Non-RT RICs 250, and the SMO Framework 260, may include one or more interfaces or may be coupled with one or more interfaces for transmitting or receiving signals, such as data, control information, or reference signals via a wired or wireless transmission medium.
[0062] In some aspects, the CU 210 may be logically split into one or more CU user plane (CU-UP) units and one or more CU control plane (CU-CP) units. A CU-UP unit may communicate bidirectionally with a CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 210 may be deployed to communicate with one or more DUs 230, as necessary, for network control and signaling. Each DU 230 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 240. For example, a DU 230 may host various layers, such as an RLC layer, a MAC layer, or one or more PHY layers, such as one or more high PHY layers or one or more low PHY layers. Each layer (which also may be referred to as a module) may be implemented with an interface for communicating signals with other layers (and modules) hosted by the DU 230, or for communicating signals with the control functions hosted by the CU 210. Each RU 240 may implement lower layer functionality. In some aspects, real-time and non-real-time aspects of control and user plane communication with the RU (s) 240 may be controlled by the corresponding DU 230.
[0063] The SMO Framework 260 may support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 260 may support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface, such as an O1 interface. For virtualized network elements, the SMO Framework 260 may interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 290) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface, such as an O2 interface. A virtualized network element may include, but is not limited to, a CU 210, a DU 230, an RU 240, a non-RT RIC 250, or a Near-RT RIC 270. In some aspects, the SMO Framework 260 may communicate with a hardware aspect of a 4G RAN, a 5G NR RAN, or a 6G RAN, such as an open eNB (O-eNB) 280, via an O1 interface. Additionally, or alternatively, the SMO Framework 260 may communicate directly with each of one or more RUs 240 via a respective O1 interface. In some deployments, this configuration can enable each DU 230 and the CU 210 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0064] The Non-RT RIC 250 may include or may implement a logical function that enables non-real-time control and optimization of RAN elements and resources, AI / ML workflows including model training and updates, or policy-based guidance of applications or features in the Near-RT RIC 270. The Non-RT RIC 250 may be coupled to or may communicate with (such as via an A1 interface) the Near-RT RIC 270. The Near-RT RIC 270 may include or may implement a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions via an interface (such as via an E2 interface) connecting one or more CUs 210, one or more DUs 230, or an O-eNB 280 with the Near-RT RIC 270.
[0065] In some aspects, to generate AI / ML models to be deployed in the Near-RT RIC 270, the Non-RT RIC 250 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 270 and may be received at the SMO Framework 260 or the Non-RT RIC 250 from non-network data sources or from network functions. In some examples, the Non-RT RIC 250 or the Near-RT RIC 270 may tune RAN behavior or performance. For example, the Non-RT RIC 250 may monitor long-term trends and patterns for performance and may employ AI / ML models to perform corrective actions via the SMO Framework 260 (such as reconfiguration via an O1 interface) or via creation of RAN management policies (such as A1 interface policies) .
[0066] The network node 110, the processing system 145 of the network node 110, the UE 120, the processing system 140 of the UE 120, the CU 210, the DU 230, the RU 240, or any other component (s) of Fig. 1 or Fig. 2 may implement one or more techniques or perform one or more operations associated with allocating codepoints for UE subgroups in LP-WUS MOs, as described in more detail elsewhere herein. For example, the processing system 145 of the network node 110, the processing system 140 of the UE 120, the CU 210, the DU 230, or the RU 240 may perform or direct operations of, for example, process 1100 of Fig. 11, process 1200 of Fig. 12, or other processes as described herein (alone or in conjunction with one or more other processors) . Memory of the network node 110 may store data and program code (or instructions) for the network node 110, the CU 210, the DU 230, or the RU 240. In some examples, the memory of the network node 110 may store data relating to a UE 120, such as RRC state information or a UE context. Memory of a UE 120 may store data and program code (or instructions) for the UE 120, such as context information. In some examples, the memory of the UE 120 or the memory of the network node 110 may include a non-transitory computer-readable medium storing a set of instructions for wireless communication. For example, the set of instructions, when executed by one or more processors (for example, of the processing system 145 or the processing system 140) of the network node 110, the UE 120, the CU 210, the DU 230, or the RU 240, may cause the one or more processors to perform process 1100 of Fig. 11, process 1200 of Fig. 12, or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, or interpreting the instructions, among other examples.
[0067] In some aspects, a UE (e.g., the UE 120) includes means for identifying an allocation of one or more codepoints associated with an LP-WUS in one or more MOs associated with an LO to one or more UE subgroups of one or more POs, wherein the allocation defines a common codepoint and one or more UE subgroup specific codepoints in an MO of the one or more MOs; or means for receiving the LP-WUS based at least in part on the allocation. The means for the UE to perform operations described herein may include, for example, one or more of communication manager 150, processing system 140, a radio, one or more RF chains, one or more transceivers, one or more antennas, one or more modems, a reception component (for example, reception component 1302 depicted and described in connection with Fig. 13) , or a transmission component (for example, transmission component 1304 depicted and described in connection with Fig. 13) , among other examples.
[0068] In some aspects, a network node (e.g., the network node 110) includes means for identifying an allocation of one or more codepoints associated with an LP-WUS in one or more MOs associated with an LO to one or more UE subgroups of one or more POs, wherein the allocation defines a common codepoint and one or more UE subgroup specific codepoints in an MO of the one or more MOs; or means for transmitting the LP-WUS based at least in part on the allocation. The means for the network node to perform operations described herein may include, for example, one or more of communication manager 155, processing system 145, a radio, one or more RF chains, one or more transceivers, one or more antennas, one or more modems, a reception component (for example, reception component 1402 depicted and described in connection with Fig. 14) , or a transmission component (for example, transmission component 1404 depicted and described in connection with Fig. 14) , among other examples.
[0069] As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.
[0070] In a wireless network, a UE may support an LP-WUS, which may serve to save UE battery power. The UE may employ a separate hardware with a simpler architecture and a lower operation power, as compared to traditional hardware, to receive the LP-WUS. The LP-WUS may serve as a heartbeat signal. For NR, the LP-WUS may trigger the UE to monitor a PDCCH signal. The LP-WUS may trigger the UE to monitor a paging PDCCH signal for RRC idle / inactive states. The LP-WUS may trigger the UE to monitor a paging early indication PDCCH signal for RRC idle / inactive states. The LP-WUS may trigger the UE to monitor a data scheduling PDCCH signal for an RRC connected state. The LP-WUS may be generated by a modulation scheme that is simpler than a modulation scheme for PDCCH, such that a detection of the LP-WUS is low power consuming.
[0071] Fig. 3 is a diagram illustrating an example 300 of multiple radios in a UE.
[0072] As shown in Fig. 3, a UE may include a low power wakeup receiver (LP-WUR) 302 and a main radio 304. The UE may include the LP-WUR 302 in order to support an LP-WUS. The main radio 304 may be a legacy wireless transceiver. When the LP-WUR 302 is enabled to monitor the LP-WUS, the main radio 304 may be in a sleep mode for power saving. After the UE receives the LP-WUS, which may trigger a PDCCH monitoring for the UE, the main radio 304 may be switched on in order to monitor a PDCCH. By allowing the main radio 304 to be in the sleep mode when the LP-WUR 302 is monitoring for the LP-WUS, the UE may be able to save power. The LP-WUR 302 may have a simpler architecture and a low operation power as compared to the main radio 304.
[0073] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.
[0074] An LP-WUS may be designed for low UE operational power. A network node may transmit the LP-WUS to wake up a UE for PDCCH monitoring. A legacy PDCCH monitoring may be replaced by an LP-WUS triggered PDCCH monitoring. The UE may use a dedicated LP-WUR to detect the LP-WUS with lower complexity and lower operational power than a legacy radio.
[0075] An LO may be defined for LP-WUS monitoring. The LO may be similar to a PO. A periodicity of the LO may be the same as the UE’s iDRX cycle. Different UEs may be associated with different periodicities of the LO. Multiple LP-WUS MOs (e.g., 4 LP-WUS MOs) may be configured for the LO when multiple UE subgroups are to be paged in one iDRX cycle. At most one LP-WUS may be transmitted in an LP-WUS MO. Different LP-WUSs may be transmitted in different LP-WUS MOs of the LO. In one example, the LO may be associated with a UE RRC idle / inactive mode, as well as an RRC connected mode.
[0076] Fig. 4 is a diagram illustrating an example 400 of LP-WUS MOs.
[0077] As shown in Fig. 4, an iDRX cycle may be associated with one or more LOs. For example, the iDRX cycle may include a first LO (LO1) , a second LO (LO2) , and a third LO (LO3) . An LO of the one or more LOs may include multiple LP-WUS MOs. In this example, one LO may include 4 LP-WUS MOs. An LP-WUS may be transmitted in a given LP-WUS MO. For example, a network node may transmit the LP-WUS in the given LP-WUS MO, which may wake up a UE for PDCCH monitoring.
[0078] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with regard to Fig. 4.
[0079] An LP-WUS may indicate a codepoint corresponding to one or more UE subgroups from N subgroups for one or more POs, where N is a positive integer. At a given time, at most one codepoint indicated by one binary on-off keying (OOK) sequence (e.g., codeword) may be transmitted in an MO. A UE subgroup specific codepoint may be one codepoint corresponding to one UE subgroup that wakes up UEs in the UE subgroup to receive a paging message. A common codepoint may be one codepoint corresponding to all UE subgroups associated with the LO that wakes up all UEs in these UE subgroups to receive a short message or a system information block (SIB) update.
[0080] For an RRC idle / inactive state, UE subgroup information may be indicated using the LP-WUS. The LP-WUS may indicate a codepoint value correspond to one or more UE subgroups from N subgroups for the one or more POs. A UE monitoring of one or more MOs (e.g., up to X MOs) for the same beam within the LO may be supported, where X is a positive integer. A value of X may be larger than one. The LP-WUS may support various codepoints, which may include one codepoint corresponding to each of the UE subgroups that can be indicated by the LP-WUS (UE subgroup specific codepoint) , and / or one codepoint corresponding to all of the UE subgroups that can be indicated by the LP-WUS (common codepoint) . Additional codepoints may also be supported for the LP-WUS.
[0081] One LO may be associated with one or more POs. A duration of the LP-WUS may be sufficiently long (e.g., a statistical distribution of a detection metric normalized by an LP-WUS duration is sufficiently narrow) so that a false alarm from noise may satisfy a design target (e.g., maximum 1%) . A maximum number of codepoints (e.g., a maximum number of distinguishable binary sequences / codewords under a performance target) that are able to be represented by the LP-WUS in an MO may be based at least in part on the duration of the LP-WUS. When the maximum number of codepoints (e.g., 32 based at least in part on a length 16 orthogonal code) is larger than a number of UE subgroups per PO (e.g., 8 or 16) , the LP-WUS may indicate UE subgroups associated with multiple POs.
[0082] UEs monitoring the same PO may be divided into multiple UE subgroups, where the LP-WUS may provide a wakeup indication for each UE subgroup. In a first option, UEs monitoring the same PO may monitor the same LO. In a second option, UEs corresponding to different POs may monitor the same LO. In a third option, UEs monitoring the same PO may be divided into multiple sets of UE subgroups, where UEs within each set of UE subgroups may monitor the same LO. For an LO-to-PO mapping, UEs monitoring the same PO may monitor the same LO. For the LO-to-PO mapping from a network perspective, UEs corresponding to different POs may monitor the same LO, which may not increase a maximum number of codepoints per LO / LP-WUS. Certain conditions / restrictions may be defined for mapping multiple POs to one LO. A maximum number of POs per LO may be two or four.
[0083] A number of codepoints per MO that are able to be indicated by an LP-WUS may be independent of a number of UE subgroups per PO. The number of codepoints that are able to be indicated by the LP-WUS per MO may be related to a detection performance of the LP-WUS. For example, a longer LP-WUS may correspond to a lower false alarm rate from noise and more codepoints per MO. The number of UE subgroups per PO may be related to a false paging rate for a UE. A false paging may occur when a UE main radio is indicated to wake up when the UE is not paged. A higher number of UE subgroups per PO may correspond to a lower false paging rate. The number of codepoints that are able to be indicated by the LP-WUS per MO and the number of UE subgroups per PO may not be integer multiples of each other. For example, the number of codepoints that are able to be indicated by the LP-WUS per MO may be equal to 16, and the number of UE subgroups per PO may be equal to 6. In some cases, when an integer multiple relationship is present, a total number of codepoints including a common codepoint in one LO may not be an integer multiple of the number of UE subgroups per PO.
[0084] As an example, the LP-WUS may provide 16 codepoints in one MO, and a number of UE subgroups per PO may be 8. In this example, a total number of codepoints per LP-WUS design for one LO associated with one PO is 1+8 = 9, and a total number of codepoints per LP-WUS design for one LO associated with two POs is 1+ (2×8) =17. An integer multiple relationship may not exist in either case.
[0085] Since the number of codepoints per MO that are able to be indicated by the LP-WUS may be independent of the number of UE subgroups per PO, and since the number of codepoints per MO may not be an integer multiple of the number of UE subgroups per PO, a codepoint allocation for UE subgroups in LP-WUS MOs may not be suitable. A number of codepoints needed for one LO may be greater than a number of codepoints provided by an LP-WUS in an MO, or a number of codepoints needed for one LO may be less than a number of codepoints provided by an LP-WUS in an MO, with respect to one or more POs. A lack of available codepoints or an excess of available codepoints associated with the LP-WUS may result in a poor utilization of resources, which may degrade an overall system performance.
[0086] In various aspects of techniques and apparatuses described herein, a UE and / or a network node may identify an allocation of one or more codepoints associated with an LP-WUS in one or more MOs associated with an LO to one or more UE subgroups of one or more POs. The UE may identify the allocation based at least in part on signaling from the network node. Alternatively, the UE may identify the allocation based at least in part on a standard predefinition. The allocation may define a mapping of the one or more codepoints associated with the LP-WUS to the one or more UE subgroup groups. The allocation may define a common codepoint and one or more UE subgroup specific codepoints in an MO of the one or more MOs. Each MO in the one or more MOs may be associated with the common codepoint and / or the one or more UE subgroup specific codepoints. A plurality of codepoints (e.g., all codepoints) represented by the LP-WUS may be associated sequentially for the common codepoint and the one or more UE subgroup specific codepoints in accordance with the allocation. The UE and / or the network node may be able to allocate codepoints represented by the LP-WUS in each MO to UE subgroups of the one or more POs, such that both the common codepoint and the UE subgroup specific codepoints may be allocated in the MO, and each UE subgroup may statistically have an equal opportunity to be paged.
[0087] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by defining the allocation of codepoints, the described techniques can be used by the UE and / or the network node to identify the allocation and receive / transmit the LP-WUS based at least in part on the allocation. The allocation may define a mapping of codepoints, which may be helpful because a number of codepoints per MO may be independent of a number of UE subgroups per PO. The allocation may define the mapping of codepoints when the number of codepoints per MO is not an integer multiple of the number of UE subgroups per PO. The allocation may define an ordering of different codepoints for different UE subgroups in different POs, when the plurality of codepoints represented by the LP-WUS are mapped to the one or more UE subgroups. A proper allocation of the codepoints represented by the LP-WUS may optimize a utilization of resources (e.g., LP-WUS codepoint resources) when indicating different UE subgroups, thereby improving an overall system performance.
[0088] In some aspects, for a codepoint allocation for UE subgroups in LP-WUS MOs, codepoints represented by an LP-WUS in each MO may be allocated to UE subgroups of one or more POs associated with an LO. Both common codepoints and UE subgroup specific codepoints may be allocated in the MO. Each UE subgroup may have statistically equal opportunities to be paged based at least in part on the codepoint allocation.
[0089] Fig. 5 is a diagram illustrating an example 500 associated with allocating codepoints for UE subgroups in LP-WUS MOs. As shown in Fig. 5, example 500 includes communication between a UE (e.g., UE 120) and a network node (e.g., network node 110) . In some aspects, the UE and the network node may be included in a wireless network, such as wireless network 100.
[0090] As shown by reference number 502, the UE may identify an allocation of one or more codepoints associated with an LP-WUS in one or more MOs associated with an LO to one or more UE subgroups of one or more POs. A codepoint indicated in the LP-WUS may be a numerical value that indicates a UE or a UE group / subgroup that is being indicated to receive a PDCCH transmission (e.g., a paging PDCCH for idle and inactive modes) . In a codepoint-based indication, each codepoint may represent a specific UE or UE group / subgroup. The LO may be associated with the one or more MOs. For example, four MOs may be included in the LO. One MO may be associated with one LP-WUS. For example, at most one LP-WUS may be transmitted in an MO, where different LP-WUSs may be transmitted in different MOs of the LO. In some aspects, the allocation may define a common codepoint and one or more UE subgroup specific codepoints in an MO of the one or more MOs. The common codepoint may be a codepoint that corresponds to a plurality of UE subgroups associated with the LO (e.g., all UE subgroups associated with the LO) , where the common codepoint may allow UEs associated with the plurality of UE subgroups to wake up and receive a short message or a SIB update in idle and inactive modes. A UE subgroup specific codepoint may be a codepoint that corresponds to one UE subgroup, where the UE subgroup specific codepoint may allow UEs associated with the one UE subgroup to wake up and receive a paging message in idle and inactive modes.
[0091] In some aspects, the UE may identify the allocation based at least in part on signaling received from the network node. For example, the UE may receive, from the network node, a configuration that indicates the allocation. Alternatively, the UE may be preconfigured with the allocation. For example, the allocation may be predefined in a specification. In some aspects, the network node may also identify the allocation. In other words, the UE and the network node may be in synchronization regarding the allocation.
[0092] In some aspects, the one or more codepoints associated with the LP-WUS may be mapped sequentially for the common codepoint and the one or more UE subgroup specific codepoints based at least in part on the allocation. In other words, the allocation may define a sequential mapping of the common codepoint and the one or more UE subgroup specific codepoints using the one or more codepoints associated with the LP-WUS. In some aspects, the one or more codepoints associated with the LP-WUS may be mapped to one or more codepoints assigned for the one or more UE subgroups. The one or more codepoints assigned for the one or more UE subgroups may be sequentially and repeatedly assigned to the one or more codepoints associated with the LP-WUS in each MO of the one or more MOs. The one or more MOs may be associated with the LO.
[0093] In some aspects, as part of a sequential mapping, the one or more codepoints associated with the LP-WUS may be mapped according to a UE subgroup and then according to a PO. For example, the one or more codepoints associated with the LP-WUS may be mapped to a codepoint for a first UE subgroup in a first PO, a codepoint for a second UE subgroup in the first PO, and up to a codepoint for a last UE subgroup in the first PO. Afterward, as part of the sequential mapping, the one or more codepoints associated with the LP-WUS may be mapped to a first UE subgroup in a second PO, a codepoint for a second UE subgroup in the second PO, and up to a codepoint for a last UE subgroup in the second PO. The one or more codepoints associated with the LP-WUS may be mapped sequentially based at least in part on the UE subgroup and the PO. A non-sequential mapping may not depend on the UE subgroup and the PO. Alternatively, the one or more codepoints associated with the LP-WUS may be mapped to a codepoint for a first UE subgroup in a first PO, a codepoint for a first UE subgroup in a second PO, a codepoint for a second UE subgroup in the first PO, a codepoint for a second UE subgroup in the second PO, and so on.
[0094] In some aspects, as part of the sequential mapping, one or more codepoints associated with one or more UE subgroups and / or one or more POs may be repeatedly assigned to codepoints associated with the LP-WUS in each MO of a plurality of MOs for the LO. For example, a codepoint associated with a given UE subgroup and a given PO may be indicated in a first LP-WUS associated with a first MO, the codepoint may be repeated in a second LP-WUS associated with a second MO, and the codepoint may be repeated in a third LP-WUS associated with a third MO. In this example, the first MO, the second MO, and the third MO may all be associated with the same LO. Depending on the sequential mapping, the codepoint associated with the given UE subgroup and the given PO may be associated with different codepoint numbers in different MOs. For example, in the first MO, the codepoint may be associated with a second codepoint of the first LP-WUS, and in the second MO, the codepoint may be associated with a third codepoint of the second LP-WUS. In other words, the codepoint may be repeated across multiple MOs.
[0095] In some aspects, the common codepoint may be mapped to a first MO of the one or more MOs based at least in part on the allocation (e.g., the common codepoint may be mapped to only the first MO of the one or more MOs) . In some aspects, the common codepoint may be mapped to each MO of the one or more MOs based at least in part on the allocation (e.g., the common codepoint may be mapped to multiple MOs) . In some aspects, within a given MO, the common codepoint may be mapped to a first codepoint in W possible codepoints (e.g., W = 16) , a last codepoint in the W possible codepoints, or another codepoint in the W possible codepoints.
[0096] In some aspects, the allocation may define the common codepoint for the one or more UE subgroups, a codepoint for a first UE subgroup of the one or more subgroups in a first PO of the one or more POs, a codepoint for a second UE subgroup of the one or more subgroups in the first PO of the one or more POs, and / or a codepoint for a last UE subgroup of the one or more UE subgroups in a last PO of the one or more POs. In other words, the allocation may define codepoints for each UE subgroup and / or each PO, where the codepoints may be associated with multiple MOs.
[0097] In some aspects, the one or more codepoints associated with the LP-WUS may be mapped to one or more codepoints assigned for the one or more UE subgroups based at least in part on a hopping. The hopping may be associated with a time varying or LO dependent circular shift. The hopping may prevent certain UE subgroups from associated with one MO, such that a plurality of UE subgroups may have an equal chance of being paged in multiple MOs in the LO. In some aspects, the common codepoint may be allocated to a first MO of the one or more MOs. A quantity of the one or more codepoints associated with the LP-WUS per MO of the one or more MOs may be an integer multiple of a quantity of UE subgroups per PO of the one or more POs. The one or more UE subgroup specific codepoints may be sequentially mapped to the one or more codepoints associated with the LP-WUS in the one or more MOs.
[0098] In some aspects, the allocation may be based at least in part on a hopping that is applied to the one or more UE subgroup specific codepoints in the MO. The MO may be a first MO of the one or more MOs. The hopping may be associated with a time varying or LO dependent circular shift. In some aspects, the allocation may be based at least in part on a mapping from a logical MO index to a physical MO index in the LO. The mapping may be based at least in part on a time varying or LO dependent shift. In some aspects, the one or more MOs may include two MOs. The common codepoint may be associated with a first MO and / or a second MO. The common codepoint may be associated with a given codepoint in the first MO and / or the second MO.
[0099] As shown by reference number 504, the UE may receive, from the network node, the LP-WUS based at least in part on the allocation. The allocation may indicate the common codepoint and / or the UE subgroup specific codepoint. When the UE is included in the one or more UE subgroups indicated via the UE subgroup specific codepoint in the LP-WUS, the UE may be able to receive the LP-WUS. In other words, the UE may be able to determine that a specific LP-WUS is intended for the UE based at least in part on the UE subgroup specific codepoint. The UE may wake up for a PDCCH monitoring based at least in part on the LP-WUS.
[0100] As shown by reference number 502, the UE may identify an allocation of one or more codepoints associated with an LP-WUS in one or more MOs associated with an LO to one or more UE subgroups of one or more POs.
[0101] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with regard to Fig. 5.
[0102] Fig. 6 is a diagram illustrating an example 600 associated with allocating codepoints for UE subgroups in LP-WUS MOs.
[0103] In some aspects, one or more codepoints (e.g., all codepoints) represented by an LP-WUS may be associated sequentially with a common codepoint and UE subgroup specific codepoints. In some aspects, a mapping from codepoints assigned for UE subgroups sequentially to codepoints represented by the LP-WUS in each MO for LO may be defined. Codepoints may be sorted in a given order (e.g., the order may be determined) , such that a common codepoint for a plurality of UE subgroups (e.g., all UE subgroups) may occur first, which may be followed by a codepoint for a first UE subgroup in a first PO, a codepoint for a second UE subgroup in the first PO, and additional codepoints until a last UE subgroup for a last PO associated with the LO is reached. The mapping may include 1 + (M×N) codepoints, where M is a number of POs associated with the LO and N is a number of UE subgroups per PO. Codepoints may be sequentially and repeatedly assigned to codepoints represented by the LP-WUS in each MO of all MOs for the LO. The common codepoint may be mapped to a first MO of the LO (e.g., the common codepoint may only be mapped to the first MO of the LO) .
[0104] As shown in Fig. 6, M=2 POs may be associated with the LO, N=8 UE subgroups may be per PO, K=2 MOs may be for the LO, and W=16 codepoints may be supported by the LP-WUS (e.g., by length 8 Hadamard sequences) , where M, N, K, and W are positive integers.
[0105] As shown by reference number 602, for MO0, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be a common codepoint. A second codepoint (e.g., C1) may be associated with a first UE subgroup in a first PO. The second codepoint may be associated with “SG0, 0” , where a first “0” (before the comma) is an index for a PO and a second “0” (after the comma) is an index for a UE subgroup (SG) . For MO0, a last codepoint (e.g., C15) may be associated with “SG1, 6” , where “1” is an index for a PO and “6” is an index for a UE subgroup. For MO1, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be associated with “SG1, 7” , which was unable to be indicated in MO0. A second codepoint (e.g., C1) may be a common codepoint. For MO1, a last codepoint (e.g., C15) may be associated with “SG1, 5” . In this example, a common codepoint may be repeated in each MO. In this example, codepoints associated with “SG0, 0” , “SG0, 1” and other UE subgroups may be repeated across MO0 and MO1.
[0106] As shown by reference number 604, for MO0, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be a common codepoint. A second codepoint (e.g., C1) may be associated with a first UE subgroup in a first PO. The second codepoint may be associated with “SG0, 0” . For MO0, a last codepoint (e.g., C15) may be associated with “SG1, 6” , where “1” is an index for a PO and “6” is an index for a UE subgroup. For MO1, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be associated with “SG1, 7” , which was unable to be indicated in MO0. A second codepoint (e.g., C1) may be associated with “SG0, 0” . For MO1, a last codepoint (e.g., C15) may be associated with “SG1, 6” . In this example, a common codepoint may be mapped to MO0 (e.g., a first MO) (e.g., the common codepoint may only be mapped to MO0) .
[0107] As indicated above, Fig. 6 is provided as an example. Other examples may differ from what is described with regard to Fig. 6.
[0108] Fig. 7 is a diagram illustrating an example 700 associated with allocating codepoints for UE subgroups in LP-WUS MOs.
[0109] In one example, certain UE subgroups, such as UE subgroups associated with “SG1, 6” and “SG1, 7” , may be paged in one MO (e.g., certain UE subgroups may only be paged in one MO) . When an LP-WUS is affected by jammer interference, UE subgroups associated with “SG1, 6” and “SG1, 7” may become more vulnerable than other UE subgroups due to less opportunities for the UE subgroups associated with “SG1, 6” and “SG1, 7” to be paged.
[0110] In some aspects, a hopping may be added at least to a mapping from UE specific codepoints assigned for UE subgroups sequentially to codepoints represented by the LP-WUS in MOs for an LO. The hopping may be a time varying (e.g., LO dependent) circular shift. For example, a shift may be S×n for an nth LO and step size S, where n and S are positive integers. In some aspects, statistically all UE subgroups may have an equal probability to be paged in both MOs in the LO across LOs.
[0111] As shown by reference number 702, for MO0, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be a common codepoint. A second codepoint (e.g., C1) may be associated with “SG0, 2” . For MO0, a last codepoint (e.g., C15) may be associated with “SG0, 0” . For MO1, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be associated with “SG0, 1” . A second codepoint (e.g., C1) may be a common codepoint. For MO1, a last codepoint (e.g., C15) may be associated with “SG1, 7” . In this example, S=2 for a next LO (e.g., n=1) , such that UE subgroups associated with “SG1, 6” and “SG1, 7” may be paged in both MOs, but UE subgroups associated with “SG0, 0” and “SG0, 1” may be paged in one MO. Statistically all UE subgroups may have an equal probability to be paged in both MOs in the LO across LOs. In this example, codepoints associated with “SG0, 2” , “SG0, 3” and other UE subgroups may be repeated across MO0 and MO1.
[0112] As shown by reference number 704, for MO0, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be a common codepoint. A second codepoint (e.g., C1) may be associated with “SG0, 1” . For MO0, a last codepoint (e.g., C15) may be associated with “SG1, 7” . For MO1, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be associated with “SG0, 0” . A second codepoint (e.g., C1) may be associated with “SG0, 1” . For MO1, a last codepoint (e.g., C15) may be associated with “SG1, 7” . In this example, S=1 for a next LO (e.g., n=1) , and a common codepoint may be allocated in one MO.
[0113] As indicated above, Fig. 7 is provided as an example. Other examples may differ from what is described with regard to Fig. 7.
[0114] Fig. 8 is a diagram illustrating an example 800 associated with allocating codepoints for UE subgroups in LP-WUS MOs.
[0115] In some aspects, codepoints for UE subgroups may be mapped to codepoints indicated by an LP-WUS in one or more MOs when a common codepoint is transmitted in one MO (e.g., the common codepoint is only transmitted in one MO) and a number of codepoints indicated by the LP-WUS per MO may be an integer multiple of a number of UE subgroups per PO. In some aspects, the common codepoint may be allocated to a first MO (e.g., only the first MO) and a number of codepoints indicated by the LP-WUS per MO may be an integer multiple of the number of UE subgroups per PO. UE subgroup specific codepoints may be sequentially mapped to remaining codepoints (not for a common codepoint) indicated by the LP-WUS in the first MO and codepoints indicated by the LP-WUS in other MOs. In some aspects, hopping (e.g., a time varying shift) may be applied to the UE subgroup specific codepoints in the first MO.
[0116] As shown by reference number 802, for MO0, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be a common codepoint. A second codepoint (e.g., C1) may be associated with “SG0, 0” . For MO0, a last codepoint (e.g., C15) may be associated with “SG1, 6” . For MO1, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be associated with “SG0, 0” . A second codepoint (e.g., C1) may associated with “SG0, 1” . For MO1, a last codepoint (e.g., C15) may be associated with “SG1, 7” . In this example, S=1 for a first LO and a second LO, and the common codepoint may be allocated for MO0 and not for MO1. In this example, a UE subgroup associated with “SG1, 7” may not be indicated by the LP-WUS in MO0 (e.g., due to the common codepoint in MO0) . The UE subgroup associated with “SG1, 7” may be indicated by the LP-WUS in MO1 (e.g., due to the lack of common codepoint in MO1) . In this example, codepoints associated with “SG0, 1” , “SG0, 2” and other UE subgroups may be repeated across MO0 and MO1.
[0117] As shown by reference number 804, for MO0, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be a common codepoint. A second codepoint (e.g., C1) may be associated with “SG0, 1” , which may be due to hopping applied to UE subgroup specific codepoints in MO0. In other words, in MO0, a UE subgroup associated with “SG0, 0” may be skipped. For MO0, a last codepoint (e.g., C15) may be associated with “SG1, 7” . For MO1, a mapping may be performed for a plurality of codepoints (e.g., 16 codepoints) . A first codepoint (e.g., C0) may be associated with “SG0, 0” . A second codepoint (e.g., C1) may associated with “SG0, 1” . For MO1, a last codepoint (e.g., C15) may be associated with “SG1, 7” . In this example, S=1 for a first LO and a second LO, and the common codepoint may be allocated for MO0 and not for MO1. In this example, a UE subgroup associated with “SG1, 7” may be indicated by the LP-WUS in MO0 (e.g., due to a time varying shift applied in MO0) . The UE subgroup associated with “SG1, 7” may be indicated by the LP-WUS in MO1 (e.g., due to the lack of common codepoint in MO1 and due to no time varying shift being applied in MO1) .
[0118] As indicated above, Fig. 8 is provided as an example. Other examples may differ from what is described with regard to Fig. 8.
[0119] Fig. 9 is a diagram illustrating an example 900 associated with allocating codepoints for UE subgroups in LP-WUS MOs.
