AI Technical Summary
Current wireless communication systems lack mechanisms for indicating low power wake up signal (LP-WUS) subgrouping support by user equipment (UE) and assigning subgrouping identifiers, leading to inefficient power consumption and false paging alarms.
UEs transmit a capability indication for LP-WUS subgrouping, receive subgrouping identifiers from network entities, and wake up to monitor occasions based on multiple paging types, including LP-WUS and legacy paging, to reduce power consumption and false alarms.
LP-WUS subgrouping techniques enable efficient power management and reduced false paging alarms by allowing UEs to monitor specific subgrouping occasions, optimizing power usage and improving system performance.

[0001] FIELD OF TECHNOLOGY
[0002] The following relates to wireless communications, including techniques for low power wake up signal subgrouping.BACKGROUND
[0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power) . Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA) , time division multiple access (TDMA) , frequency division multiple access (FDMA) , orthogonal FDMA (OFDMA) , or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) . A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .SUMMARY

[0063] In some wireless communications systems, a network entity may transmit a low power wake up signal (LP-WUS) to a user equipment (UE) . When the UE is in an idle or inactive mode, the UE may monitor for the LP-WUS in either a duty-cycle mode or a continuous mode. In some cases, the UE may support LP-WUS with a paging early indication (PEI) or may support LP-WUS without the PEI. In the duty cycle mode, the UE may monitor for LP-WUS based on LP-WUS occasions that are derived based on paging occasions or PEI occasions. In the continuous mode, the UE may monitor for LP-WUS in occasions that are not related to paging occasions or PEI occasions. Reception of the LP-WUS may trigger the UE to monitor paging occasion associated with legacy paging (e.g., physical downlink control channel (PDCCH) scheduling of the paging message on physical downlink shared channel (PDSCH) ) . In some cases, after being woken up by LP-WUS, the UE may also monitor legacy PEI, if PEI is configured by the network entity and if PEI is supported by the UE, before monitoring the paging occasion associated with legacy paging. In some cases, UE subgrouping may be used to reduce UE power consumption and to reduce the false paging alarm. A UE may be assigned to a subgroup, and the UE may monitor for occasions associated with the assigned subgroup which may be less monitoring than monitoring all of the occasions. UEs may be assigned to a paging subgroup and a PEI subgroup. Currently, there are no mechanisms for indicating LP-WUS subgrouping support by the UE and indicating an LP-WUS subgrouping identifier to the UE.
[0064] Techniques for LP-WUS subgrouping may be employed. In some examples, the UE may transmit, to a core network entity, a capability indication, and the capability indication may indicate a support of LP-WUS subgrouping. The UE may receive, from the core network entity, a core network assigned LP-WUS subgrouping identifier or a paging subgrouping identifier. The paging subgrouping identifier may be based on supporting at least two paging types, such as a LP-WUS paging type and a legacy paging type or the LP-WUS paging type, a PEI paging type, and the legacy paging type. The UE may receive, from the RAN network entity, LP-WUS configuration information and an indication of a support of a core network assigned LP-WUS subgrouping type, a UE assigned LP-WUS subgrouping type, or both. In some examples, the RAN network entity may receive, from the core network entity, the core network assigned LP-WUS subgrouping identifier. The UE and the RAN network entity may determine the UE assigned LP-WUS subgrouping identifier. The RAN network entity may transmit, to the UE, a LP-WUS paging type and a legacy paging type or the LP-WUS paging type, a PEI paging type, and the legacy paging type. The UE may wake up to monitor an occasion based on the first LP-WUS subgrouping identifier or the paging subgrouping identifier and the paging types.
[0065] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further described in the context of a resource diagram and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for LP-WUS subgrouping.
[0066] FIG. 1 shows an example of a wireless communications system 100 that supports techniques for LP-WUS subgrouping in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., network entities 105) , one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0067] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via communication link (s) 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish the communication link (s) 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0068] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices in the wireless communications system 100 (e.g., other wireless communication devices, including UEs 115 or network entities 105) , as shown in FIG. 1.
[0069] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein) , a UE 115 (e.g., any UE described herein) , a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0070] In some examples, network entities 105 may communicate with a core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link (s) 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via backhaul communication link (s) 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via the core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication link (s) 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0071] One or more of the network entities 105 or network equipment described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (e.g., a network entity 105 or a single RAN node, such as a base station 140) .
[0072] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among multiple network entities (e.g., network entities 105) , such as an integrated access and backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 105 may include one or more of a central unit (CU) , such as a CU 160, a distributed unit (DU) , such as a DU 165, a radio unit (RU) , such as an RU 170, a RAN Intelligent Controller (RIC) , such as an RIC 175 (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) system, such as an SMO system 180, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more of the network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0073] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaptation protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs) , or some combination thereof, and the DUs 165, RUs 170, or both may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or multiple different RUs, such as an RU 170) . In some cases, a functional split between a CU 160 and a DU 165 or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities 105) that are in communication via such communication links.
[0074] In some wireless communications systems (e.g., the wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more of the network entities 105 (e.g., network entities 105 or IAB node (s) 104) may be partially controlled by each other. The IAB node (s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station) . The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node (s) 104) via supported access and backhaul links (e.g., backhaul communication link (s) 120) . IAB node (s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with an independent set of antennas for relay of communications with UEs 115 or may share the same antennas (e.g., of an RU 170) of IAB node (s) 104 used for access via the DU 165 of the IAB node (s) 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB node (s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node (s) 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., the IAB node (s) 104 or components of the IAB node (s) 104) may be configured to operate according to the techniques described herein.
[0075] For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor) , IAB node (s) 104, and one or more UEs 115. The IAB donor may facilitate connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130) . That is, an IAB donor may refer to a RAN node with a wired or wireless connection to the core network 130. The IAB donor may include one or more of a CU 160, a DU 165, and an RU 170, in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link) . The IAB donor and IAB node (s) 104 may communicate via an F1 interface according to a protocol that defines signaling messages (e.g., an F1 AP protocol) . Additionally, or alternatively, the CU 160 may communicate with the core network 130 via an interface, which may be an example of a portion of a backhaul link, and may communicate with other CUs (e.g., including a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of another portion of a backhaul link.
[0076] IAB node (s) 104 may refer to RAN nodes that provide IAB functionality (e.g., access for UEs 115, wireless self-backhauling capabilities) . A DU 165 may act as a distributed scheduling node towards child nodes associated with the IAB node (s) 104, and the IAB-MT may act as a scheduled node towards parent nodes associated with IAB node (s) 104. That is, an IAB donor may be referred to as a parent node in communication with one or more child nodes (e.g., an IAB donor may relay transmissions for UEs through other IAB node (s) 104) . Additionally, or alternatively, IAB node (s) 104 may also be referred to as parent nodes or child nodes to other IAB node (s) 104, depending on the relay chain or configuration of the AN. The IAB-MT entity of IAB node (s) 104 may provide a Uu interface for a child IAB node (e.g., the IAB node (s) 104) to receive signaling from a parent IAB node (e.g., the IAB node (s) 104) , and a DU interface (e.g., a DU 165) may provide a Uu interface for a parent IAB node to signal to a child IAB node or UE 115.
[0077] For example, IAB node (s) 104 may be referred to as parent nodes that support communications for child IAB nodes, or may be referred to as child IAB nodes associated with IAB donors, or both. An IAB donor may include a CU 160 with a wired or wireless connection (e.g., backhaul communication link (s) 120) to the core network 130 and may act as a parent node to IAB node (s) 104. For example, the DU 165 of an IAB donor may relay transmissions to UEs 115 through IAB node (s) 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of the IAB donor may signal communication link establishment via an F1 interface to IAB node (s) 104, and the IAB node (s) 104 may schedule transmissions (e.g., transmissions to the UEs 115 relayed from the IAB donor) through one or more DUs (e.g., DUs 165) . That is, data may be relayed to and from IAB node (s) 104 via signaling via an NR Uu interface to MT of IAB node (s) 104 (e.g., other IAB node (s) ) . Communications with IAB node (s) 104 may be scheduled by a DU 165 of the IAB donor or of IAB node (s) 104.
[0078] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support test as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 180) .
[0079] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.
[0080] The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate as relays, as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
[0081] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication link (s) 125 (e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link (s) 125. For example, a carrier used for the communication link (s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities, such as one or more of the network entities 105) .
[0082] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) , such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
[0083] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1 / (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .
[0084] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems, such as the wireless communications system 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0085] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
[0086] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE) .
[0087] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.
[0088] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception concurrently) . In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 may include entering a power saving deep sleep mode when not engaging in active communications, operating using a limited bandwidth (e.g., according to narrowband communications) , or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs) ) within a carrier, within a guard-band of a carrier, or outside of a carrier.
[0089] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0090] In some examples, a UE 115 may be configured to support communicating directly with other UEs (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a D2D communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to one or more of the UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.
[0091] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
[0092] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0093] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) RAT, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0094] A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0095] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0096] In some wireless communications systems, the network entity 105 may transmit a LP-WUS to a UE 115. When the UE 115 is in an idle or inactive mode, the UE 115 may monitor for the LP-WUS in either a duty-cycle mode or a continuous mode. In some cases, the UE 115 may support LP-WUS with a PEI or may support LP-WUS without the PEI. In the duty cycle mode, the UE 115 may monitor for LP-WUS based on LP-WUS occasions that are derived based on paging occasions or PEI occasions. In the continuous mode, the UE 115 may monitor for LP-WUS in occasions that are not related to paging occasions or PEI occasions. Reception of the LP-WUS may trigger the UE 115 to monitor paging occasion associated with legacy paging (e.g., PDCCH scheduling of the paging message on PDSCH) . In some cases, after waken up by LP-WUS, the UE 115 may also monitor legacy PEI, if PEI is configured by the network entity 105 and if PEI is supported by the UE 115, before monitoring the paging occasion associated with legacy paging. In some cases, UE subgrouping may be used to reduce UE power consumption and to reduce the false paging alarm. A UE 115 may be assigned to a subgroup, and the UE 115 may monitor for occasions associated with the assigned subgroup which may be less monitoring than monitoring all of the occasions. UEs 115 may be assigned to a paging subgroup and a PEI subgroup. Currently, there are no mechanisms for indicating LP-WUS subgrouping support by the UE 115 and indicating an LP-WUS subgrouping identifier to the UE 115.
[0097] Techniques for LP-WUS subgrouping may be employed. In some examples, the UE 115 may transmit, to a core network 130 or core network entity, a capability indication, and the capability indication may indicate a support of LP-WUS subgrouping. The UE 115 may receive, from the core network 130, a core network assigned LP-WUS subgrouping identifier or a paging subgrouping identifier. The paging subgrouping identifier may be based on supporting at least two paging types, such as a LP-WUS paging type and a legacy paging type or the LP-WUS paging type, a PEI paging type, and the legacy paging type. The 115 UE may receive, from the RAN network entity or network entity 105, LP-WUS configuration information and an indication of a support of a core network assigned LP-WUS subgrouping type, a UE assigned LP-WUS subgrouping type, or both. In some examples, the network entity 105 may receive, from the core network 130, the core network assigned LP-WUS subgrouping identifier. The UE 115 and the network entity 105 may determine the UE assigned LP-WUS subgrouping identifier. The network entity 105 may transmit, to the UE 115, a LP-WUS paging type and a legacy paging type or the LP-WUS paging type, a PEI paging type, and the legacy paging type. The UE 115 may wake up to monitor an occasion based on the first LP-WUS subgrouping identifier or the paging subgrouping identifier and the paging types.
[0098] FIG. 2 shows an example of a wireless communications system 200 that supports techniques for LP-WUS subgrouping in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement aspects of or may be implemented by aspects of the wireless communications system 100. For example, the wireless communications system 200 may include a UE 115-a, which may be an example of a UE 115 as described herein. The wireless communications system 200 may include a network entity 105-a, which may be an example of a network entity 105 as described herein. The wireless communications system 200 may also include a core network 130-a, which may be examples of the core network 130 as described here.
[0099] The UE 115-a may communicate with the network entity 105-a using a communication link 125-a. The communication link 125-a may be an example of a 6th generation (6G) , a NR or LTE link between the UE 115-a and the network entity 105-a. The UE 115-a may establish one or more communication links (e.g., via the communication link 125-a) with the network entity 105-a. The communication link 125-a may include bi-directional links that enable both uplink and downlink communications. For example, the network entity 105-a may transmit downlink signals (e.g., downlink transmissions 205) , such as downlink control signaling and downlink data signals, to the UE 115-a using the communication link 125-a, and the UE 115-a may transmit uplink signals (e.g., uplink transmissions 210) , such as uplink control signaling and uplink data signals, to the network entity 105-a using the communication link 125-a.
[0100] In some examples, the network entity 105-a may communicate with the core network 130-a or core network entity via a backhaul communication link 120-a using a communication link 125-a (e.g., in accordance with an S1, N2, N3, or other interface protocol) . The UE 115-a may communicate with the core network 130-a via the network entity 105-a or a direct communication link. The core network 130-a may transmit control signaling and data signals to the network entity 105-a, and the network entity 105-a may transmit control signaling and data signals to the core network 130-a. The UE 115-a may communicate control signaling and data signals to the core network 130-a.
[0101] In some examples, the UE 115-a may operate in an idle or inactive mode, and the network entity 105-a may transmit, to the UE 115-a, an LP-WUS (e.g., LP-WUS paging type signal) . When the UE 115-a is in an idle or inactive mode, the UE 115-a may perform duty-cycled monitoring or continuous monitoring for the LP-WUS. In some cases, the UE 115-a may support LP-WUS with PEI (e.g., PEI paging type signal) or the UE 115-a may support LP-WUS without PEI. In the duty cycle mode, the UE 115-a may monitor for LP-WUS based on monitoring occasions of LP-WS occasions that are derived based on paging occasions or PEI occasions. In the continuous mode, the UE 115-a may monitor for LP-WUS in occasions that are not related to POs or PEI occasions. Duty-cycled monitoring may have lower UE power consumption but higher paging latency than continuous monitoring.
[0102] Reception of the LP-WUS may trigger the UE 115-a to monitor paging associated with a PDCCH or a PDSCH. In some cases, after reception of LP-WUS, the UE may monitor PEI and then paging. In some cases, UE subgrouping may be used to reduce UE power consumption. The UE 115-a may be assigned to a subgroup, and the UE 115-a may monitor for occasions associated with the assigned subgroup which may be less monitoring than monitoring all of the occasions. The UE 115-a may be assigned to at least one of a paging subgroup, a PEI subgroup, and a LP-WUS subgroup. In some cases, UE subgrouping indication in LP-WUS and PEI may be used together to reduce false paging alerts.
[0103] In some examples, LP-WUS and paging may be used together for a wake-up procedure without PEI. For latency access, LP-WUS reception may be followed by paging reception and then a random access procedure. False alarms may be reduced with UE subgrouping for LP-WUS, and the LP-WUS may be considered as replacing PEI. In some examples, LP-WUS, PEI and paging (e.g., legacy paging type signal) may be used together for a wake-up procedure. For latency access, LP-WUS reception may be followed by PEI reception that may be followed by paging reception and then a random access procedure. False alarms may be reduced with UE subgrouping for LP-WUS and PIE.
[0104] In some cases, UE subgrouping in LP-WUS may be implemented by the communication system 200. After reception of the LP-WUS, the UE 115-a may wake-up and monitor occasions, such as paging occasions (e.g., legacy paging type occasions) . In some cases, an association may exist between the LP-WUS occasions and the paging occasions. LP-WUS subgrouping information corresponding to two or more bits may be indicated by the LP-WUS, such as including the UE subgroup information in the LP-WUS payload or from the use of multiple LP-WUS signals corresponding to different subgroups. In some cases, a subgrouping mechanism similar to PIE may be used for LP-WUS UE subgrouping. For example, the LP-WUS subgrouping identifier may be core network assigned and UE assigned.
[0105] When UE subgroup information is included in the LP-WUS payload, the procedure triggered by LP-WUS reception may be monitoring of paging occasions or PEI occasions, and the network entity 105-a transmission of paging may be LP-WUS and paging (e.g., PDCCH and PDSCH) . False paging may occur among the UEs in the cell using continuous monitoring and among the UEs sharing a paging occasion using duty-cycled monitoring. False paging may be reduced by use of UE subgrouping and increasing a quantity of the UE subgroups.
[0106] LP-WUS may be supported without supporting PEI or with supporting PEI. LP-WUS may be monitored in either duty-cycle mode or continuous mode. In the duty-cycle mode, LP-WUS may be monitored based on LP-WUS occasions derived based on either POs or PEI occasions. In the continuous mode, LP-WIS may be monitored continuously by the UE and may not be related to POs or PEI occasions. Support of PEI or LP-WUS or both PEI and LP-WUS may be based on the radio access network implementation and may be based on UE capabilities. The AMF of the core network 130-a may not be aware of whether the UE is monitoring LP-WUS or not monitoring LP-WUS in radio resource control (RRC) idle mode or inactive mode.
[0107] In some examples, the core network 130-a and the network entity 105-a may communicate signaling to support LP-WUS subgrouping via the backhaul communication link 120-a. For example, the core network 130-a may transmit, to the network entity 105-a, signaling 215 that indicates a core network assigned LP-WUS subgrouping identifier and a paging message 220. In some examples, the network entity 105-a and the UE 115-a may communicate signaling to support LP-WUS subgrouping via the communication link 125-a. For example, the network entity 105-a may transmit, to the UE, signaling 225 that indicates LP-WUS configuration information. The network entity 105-a may transmit, to the UE, paging type signaling 230, such as LP-WUS, PEI, and legacy paging. In some cases, the UE 115-a may transmit, to the core network 130-a, signaling 235 that indicates a capability indication of a support of LP-WUS subgrouping.
[0108] FIG. 3 shows an example of a process flow 300 that supports techniques for LP-WUS subgrouping in accordance with one or more aspects of the present disclosure. In some examples, the process flows 300 may implement or be implemented by aspects of the wireless communications systems 100 and 200 as described with reference to FIGs. 1 and 2. For example, the process flow 300 may be implemented by a UE 115-b, which may be an example of the UEs 115 as described with reference to FIGs. 1 and 2. The process flow 300 may be implemented by a DU 165-a, which may be an example of the DUs 165 as described with reference to FIG. 1. The process flow 300 may be implemented by a CU 160-a, which may be an example of the CUs 160 as described with reference to FIG. 1. The DU 165-a and the CU 160-a may be included in the network entity 105 and network entity 105-a of FIGs. 1 and 2. The process flow 300 may be implemented by an AMF of a core network 130-b, and the core network 130-b may be an example of the core network 130 and 130-a as described with reference to FIGs. 1 and 2. The process flow 300 illustrates signaling associated with core network assigned LP-WUS subgrouping.
[0109] In some examples, the operations illustrated in process flow 300 may be performed by hardware (e.g., including circuitry, processing blocks, logic components, and other components) , code (e.g., software executed by a processor) , or any combination thereof. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.
[0110] At 305, the UE 115-b may transmit, to the AMF of the core network 130-b, a capability indication, and the capability indication may indicate a support of LP-WUS subgrouping. In some examples, the capability indication may be included in a registration request message. In some cases, the capability indication may indicate a support of paging subgrouping. In some examples, the registration request message may include a paging subgrouping support indication, LP-WUS subgrouping support indication, and paging subgrouping assistance information.
[0111] Based on UE indicated capabilities, the AMF may decide whether to configure core network assigned subgrouping for PEI with no LP-WUS, for LP-WUS with no PEI, or for both PEI and LP-WUS. The UE 115-b may indicate in the UE 5F mobility management (5GMM) core network capability indication whether the UE supports LP-WUS subgrouping. The UE 115-b may include in the paging subgrouping assistance information paging probabilities for PEI without LP-WUS, for LP-WUS without PEI, or for both LP-WUS and PEI. If the AMF supports LP-WUS subgrouping and if the UE 115-b indicated the LP-WUS subgrouping support indication, the AMF may store the indication in the UE context at the AMF of the core network 130-b. At 310, the AMF may determine the core network assigned LP-WUS subgroup ID. In some cases, the AMF may determine the UE LP-WUS assistance information (e.g., LP-WUS Paging subgroupID) using information from the UE 115-b and from the DU 165-a or CU 160-a (e.g., network entity 105-a) similar to determining the subgrouping ID for PEI.
[0112] At 315, the UE 115-b may receive, from the AMF of the core network 130-b, the LP-WUS assistance information. For example, the UE 115-a may receive a registration accept message that includes the LP-WUS assistance information (e.g., the core network assigned LP-WUS subgrouping ID) . In some cases, the registration accept message may include paging early indication with paging subgrouping (PEIPS) assistance information. In some examples, the AMF may include the LP-WUS assistance information as a separate information element or another field in the existing AMF PEIPS assistance information. In some cases, the AMF may use the UE configuration update procedure to update the AMF LP-WUS assistance information in the UE 115-a and RAN network entity. In some cases, the core network 130-b may transmit a paging subgrouping ID, and the paging subgrouping ID may be based on supporting LP-WUS and legacy paging or LP-WUS, PEI and legacy paging.
[0113] When the UE 115-b has an active emergency PDU session, the UE 115-b may not signal the LP-WUS subgrouping support indication in the registration request message. If the UE 115-b activated the emergency PDU session occurs after registering with the core network 130-b, the AMF may not support LP-WUS core network assigned subgrouping and may not send the core network assigned PEIPS or LP-WUS assistance information to RAN network entity. For the active emergency PDU session, the RAN network entity may support the UEID-based subgrouping for LP-WUS, and the UE 115-b may monitor for LP-WUS when there is emergency PDU session.
[0114] At 320, the AMF of the core network 130-b may send a paging message to the CU 160-a of the RAN network entity. The paging message may include the PEIPS assistance information and the LP-WUS assistance information. The AMF may indicate the core network assigned subgroup identifier (s) , such as the core network assigned LP-WUS subgroup ID or the core network assigned PEI subgroup ID, for the UE 115-b when sending the paging message to the RAN network entity. For example, the core network assigned LP-WUS subgroup ID or the core network assigned PEI subgroup ID may be included in the paging message.
[0115] In some examples, the AMF of the core network 130-b may transmit the paging message at an earlier time for a UE supporting LP-WUS than UE supporting PEI but not supporting LP-WUS. The earlier transmission may allow the UE supporting LP-WUS to be ready for the paging occasion. The offset time between the LP-WUS and the paging occasion is longer than the offset time between the PEI and the paging occasion as the offset time between the LP-WUS and the paging occasion may include a transition time to start up a main receiver to be ready for PDCCH monitoring in case of LP-WUS.
[0116] In some cases, the AMF of the core network 130-b may provide the AMF LP-WUS assistance information to RAN network entity as part of the RRC inactive assistance information. In some examples, the LP-WUS assistance information may be included in the core network assistance information for the RRC inactive information element during UE context setup or modification in RAN and during handover (HO) signaling messages including next-generation application protocol (NGAP) HO request message or path switch request acknowledge messages.
[0117] At 325, the CU 160-a of the RAN network entity may transmit the paging message to the DU 165-a of the RAN network entity. The paging message may include the PEIPS assistance information, UE assigned ID (UEID) subgrouping support indication, LP-WUS subgrouping support indication, LP-WUS UEID subgrouping support indication, and the LP-WUS assistance information. The core network assigned subgroup IDs, such as the core network assigned LP-WUS subgroup ID or the core network assigned PEI subgroup ID, for the UE 115-b may be included in the paging message.
[0118] At 330, the DU 165-a may transmit the LP-WUS, the PEI or both the LP-WUS and the PEI. The DU 165-a and CU 160-a may be considered as the RAN network entity. In some cases, the DU 165-a may determine to transmit the LP-WUS, the PEI or both LP-WUS and PEI using the core network assigned subgrouping IDs based on the UE 115-b and the RAN network entity capabilities indicated for paging.
[0119] Techniques for LP-WUS subgrouping may be employed. In some examples, the UE 115-b may transmit, to the core network 130-b, an indication on a support of at least one of LP-WUS subgrouping or paging subgrouping based on the type of PDU sessions supported for the UE 115-b. The UE 115-b may receive, from the core network 130-b, one or more identifiers in a paging subgrouping assistance information including at least one of a core network assigned paging subgrouping identifier or a core network assigned LP-WUS subgrouping identifier. The UE 115-b may receive a LP-WUS configuration from a RAN network entity, including an indication of support for LP-WUS core network assigned subgrouping ID and a UE assigned subgrouping ID (e.g., UEID-based subgrouping) . The UE 115-b may determine the UE assigned LP-WUS subgrouping ID based on whether both LP-WUS and PEI are supported or LP-WUS without PEI is supported. The UE 115-b may determine to wake up a main radio for monitoring paging occasions based on identification of the core network assigned LP-WUS subgrouping ID or the UE assigned LP-WUS subgrouping ID in the received LP-WUS.
[0120] In some cases, the core network 130-b may receive, from the UE 115-b, a capabilities indication on the support of at least one of the LP-WUS subgrouping or the paging subgrouping. The core network 130-b may decide whether to assign the UE 115-b with a core network assigned subgrouping ID for paging subgrouping or for LP-WUS subgrouping or for both paging subgrouping and LP-WUS subgrouping based on the received UE capabilities indication. The core network 130-b may determining the LP-WUS subgrouping ID for the UE 115-b using the information from the UE 115-b and a RAN network entity. The core network 130-b may transmit the LP-WUS subgrouping ID in paging subgrouping assistance information to the RAN network entity and to the UE 115-b.
[0121] FIG. 4 shows an example of a resource diagram 400 that supports techniques for LP-WUS subgrouping in accordance with one or more aspects of the present disclosure. The resource diagram 400 may implement aspects of or may be implemented by aspects of the wireless communications system 100 and wireless communications system 200.
[0122] The resource diagram 400 illustrates a diagram 405 with an LP-WUS occasion 410 (e.g., LP-WUS paging type occasion) , a PEI occasion 415 (e.g., PEI paging type occasion) , and a paging occasion 420 (e.g., legacy paging type occasion) . If LP-WUS with core network assigned subgrouping is supported, the AMF of the core network 130-b may divide the UEs served by the core network 130-b into paging subgroups. For example, the AMF may assign a core network subgroup ID for each UE, and the AMF may assign an LP-WUS core network subgroup ID 425 which may be a hierarchy under a PEI core network subgroup ID 430 which may be under a legacy paging UE subgroup ID 435. In some cases, the core network may determine to use the PEI core network assigned subgrouping ID as the LP-WUS core network assigned subgrouping ID.
[0123] The resource diagram 400 illustrates a diagram 440 with subgroups within paging occasion. For example, the paging occasion PO#1 445 may include N subgroups 450 within PO#1, and the paging occasion P0#2 455 may include N subgroups. The AMF may be agnostic to whether the UE 115-b or RAN network entity are using both LP-WUS and PEI. The UE 115-a may be informed of both the core network assigned PEI subgroup ID and the core network assigned LP-WUS subgroup ID by the AMF. The UE 115-b may determine whether to monitor occasions based on the core network assigned subgroup ID indicated in LP-WUS or PEI.
[0124] FIG. 5 shows an example of a process flow 500 that supports techniques for LP-WUS subgrouping in accordance with one or more aspects of the present disclosure. In some examples, the process flows 500 may implement or be implemented by aspects of the wireless communications systems 100 and 200 as described with reference to FIGs. 1 and 2. For example, the process flow 500 may be implemented by a UE 115-c, which may be an example of the UEs 115 as described with reference to FIGs. 1 and 2. The process flow 500 may be implemented by a which may be an example of the network entities 105 as described with reference to FIGs. 1 and 2. The process flow 500 may illustrate signaling associated with UE assigned LP-WUS subgrouping.
[0125] In some examples, the operations illustrated in process flow 500 may be performed by hardware (e.g., including circuitry, processing blocks, logic components, and other components) , code (e.g., software executed by a processor) , or any combination thereof. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.
[0126] At 505, the network entity 105-b (e.g., RAN network entity) may transmit a LP-WUS configuration in system information to the UE 115-b. The LP-WUS configuration may include LP-WUS subgroup configuration. The LP-WUS information included in the system information may be a quantity of paging occasion per LP-WUS (POperLP-WUS) , a quantity of total LP-WUS subgroups (TotalLPWUSsubgroups) , and a quantity of LP-WUS UE subgroups (LPWUSUEsubgroups) . In some cases, the network entity 105-b may transmit, to the UE 115-c, an indication of support of a first LP-WUS subgrouping assignment type (e.g., core network assigned subgrouping) , a second LP-WUS subgrouping assignment (e.g., UEID-based subgrouping) , or both.
[0127] At 510, the UE 115-c may determine the UE-assigned subgroup ID for LP-WUS. At 515, the network entity 105-b may determine the UE-assigned subgroup ID for LP-WUS. The UE 115-c and the network entity 105-a may determine the UE-assigned subgroup ID for LP-WUS UE differently based on whether both LP-WUS and PEI are supported or whether LP-WUS is supported without PEI. For LP-WUS without PEI (e.g., no PEI supported in the cell) , the LP-WUS subgroup ID may be derived similar to the PEI subgroup ID based on the TotalLPWUSsubgroups, LPWUSUEsubgroups, and the quantity of paging occasions. For LP-WUS and PEI supported, the LP-WUS UE-assigned subgroup ID may be derived based on TotalLPWUSsubgroups and LPWUSUEsubgroups indicating the further subgrouping for PEI subgroups, and the quantity of PEI occasions per paging frame.
[0128] At 520, the network entity 105-b may transmit LP-WUS (e.g., LP-WUS type signals) , PEI (e.g., PEI type signals) or both LP-WUS and PEI to the UE 115-c. The UE 115-c may wake up to monitor the LP-WUS, PEI or both LP-WUS and PEI.
[0129] In some examples, the network entity 105-b may transmit an LP-WUS configuration to the UE 115-c, including the indication of support for at least one of LP-WUS core network assigned subgrouping ID and the LP-WUS UEID-based subgrouping ID. The network entity 105-b may receive the LP-WUS subgrouping ID in the paging subgrouping assistance information from the core network 130-b. The network entity 105-b may determine the UE assigned LP-WUS subgrouping ID based on whether both LP-WUS and PEI are supported or LP-WUS with PEI is supported. The network entity 105-b may transmit the PEI or the LP-WUS or both the PEI and LP-WUS using the core network assigned subgrouping ID or the UEID-based subgrouping ID based on the UE and RAN capabilities indicated for paging.
[0130] FIG. 6 shows an example of a process flow 600 that supports techniques for LP-WUS subgrouping in accordance with one or more aspects of the present disclosure. In some examples, the process flows 600 may implement or be implemented by aspects of the wireless communications systems 100 and 200 as described with reference to FIGs. 1 and 2. For example, the process flow 600 may be implemented by a UE 115-d, which may be an example of the UEs 115 as described with reference to FIGs. 1 and 2. The process flow 600 may be implemented by a RAN network entity 105-c which may be an example of the network entities 105 as described with reference to FIGs. 1 and 2. The process flow 600 may be implemented by a core network entity 130-c which may be an example of the core network 130 as described with reference to FIGs. 1 and 2.
[0131] In some examples, the operations illustrated in process flow 600 may be performed by hardware (e.g., including circuitry, processing blocks, logic components, and other components) , code (e.g., software executed by a processor) , or any combination thereof. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or are not performed at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.
[0132] At 605, the UE 115-d may transmit, to the core network entity 130-c, a capability indication. The capability indication may indicate a support of LP-WUS subgrouping. In some examples, the capability indication may be included in a registration request message. In some examples, the capability indication may indicate a support of paging subgrouping. In some examples, the capability indication may be included in a registration request message associated with a non-emergency PDU session.
[0133] At 610, the core network entity 130-c may determine, based at least in part on the capability indication, the LP-WUS subgrouping identifier based on supporting at least two paging subgrouping types. The at least two paging subgrouping types may include a LP-WUS paging type and a legacy paging type or the LP-WUS paging type, a paging early indication paging type, and the legacy paging type.
[0134] At 615, the UE 115-d may receive, from the core network entity 130-c, at least one of a first LP-WUS subgrouping identifier or a paging subgrouping identifier. The paging subgrouping identifier may be based on supporting at least two paging types. In some examples, the at least two paging types may include a LP-WUS paging type and a legacy paging type. In some examples, the at least two paging types may include a LP-WUS paging type, a PEI paging type and a legacy paging type. In some examples, the first LP-WUS subgrouping identifier may be included in a registration accept message or a UE configuration update message. In some examples, the registration accept message may include a PEI subgroup identifier. In some examples, the registration accept message may include a paging subgroup identifier.
[0135] At 620, the RAN network entity 105-c may receive, from the core network entity 130-c, a paging message, and the paging message may include the LP-WUS subgrouping identifier. In some examples, the paging message may include a paging early indication subgrouping identifier. In some examples, the RAN network entity 105-c may receive, from the core network 130-b, radio resource control inactive assistance information, and the radio resource control inactive assistance information may include the LP-WUS subgrouping identifier.
[0136] At 625, the UE 115-d may receive, from the RAN network entity 105-c, LP-WUS configuration information and an indication of a support of a first LP-WUS subgrouping assignment type, a second LP-WUS subgrouping assignment type, or both. In some examples, the first LP-WUS subgrouping assignment type may include a core network assigned subgrouping and the second LP-WUS subgrouping assignment type may include a UEID-based subgrouping. In some examples, the LP-WUS configuration information comprises at least one of a quantity of LP-WUS subgroups, a quantity of LP-WUS UE subgroups, a quantity of paging occasions, or a quantity of paging early indication occasions. In some examples, the UE 115-d may receive the first LP-WUS subgrouping identifier, a second paging subgrouping identifier, or a second LP-WUS subgrouping identifier.
[0137] At 630, the UE 115-d may determine, based on the LP-WUS configuration information and the indication of the support of the second LP-WUS subgrouping assignment type, a second LP-WUS subgrouping identifier. In some examples, the second LP-WUS subgrouping identifier may be based on supporting at least two paging types. The at least two paging subgrouping types may include a LP-WUS paging type and a legacy paging type or the LP-WUS paging type, the PEI paging type, and the legacy paging type.
[0138] At 635, the RAN network entity 105-c may determine, the second LP-WUS subgrouping identifier based on the second LP-WUS subgrouping assignment type. In some examples, the second LP-WUS subgrouping identifier may be based on supporting at least two paging types. The at least two paging types may include a LP-WUS paging type and a legacy paging type or the LP-WUS paging type, the PEI paging type, and the legacy paging type.
[0139] At 640, the RAN network entity 105-c may output, to the UE 115-d, at least two paging types based on the first LP-WUS subgrouping identifier or the second LP-WUS subgrouping identifier. The at least two paging types may include a LP-WUS paging type and a legacy paging type or the LP-WUS paging type, the PEI paging type, and the legacy paging type.
[0140] At 645, the UE 115-d may waking up to monitor an occasion based on the first LP-WUS subgrouping identifier or the second paging subgrouping identifier and the at least two paging types. In some examples, the UE 115-d may monitor, based on supporting the at least two paging types, one or more paging type signals. The one or more paging type signals may include LP-WUS type signals, PEI type signals or legacy paging type signals.
[0141] FIG. 7 shows a block diagram 700 of a device 705 that supports techniques for LP-WUS subgrouping in accordance with one or more aspects of the present disclosure. The device 705 may be an example of aspects of a UE 115 as described herein. The device 705 may include a receiver 710, a transmitter 715, and a communications manager 720. The device 705, or one or more components of the device 705 (e.g., the receiver 710, the transmitter 715, the communications manager 720) , may include at least one processor, which may be coupled with at least one memory, to, individually or collectively, support or enable the described techniques. Each of these components may be in communication with one another (e.g., via one or more buses) .
[0142] The receiver 710 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to techniques for LP-WUS subgrouping) . Information may be passed on to other components of the device 705. The receiver 710 may utilize a single antenna or a set of multiple antennas.
[0143] The transmitter 715 may provide a means for transmitting signals generated by other components of the device 705. For example, the transmitter 715 may transmit information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to techniques for LP-WUS subgrouping) . In some examples, the transmitter 715 may be co-located with a receiver 710 in a transceiver module. The transmitter 715 may utilize a single antenna or a set of multiple antennas.
[0144] The communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be examples of means for performing various aspects of techniques for LP-WUS subgrouping as described herein. For example, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be capable of performing one or more of the functions described herein.
[0145] In some examples, the communications manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry) . The hardware may include at least one of a processor, a digital signal processor (DSP) , a central processing unit (CPU) , an application-specific integrated circuit (ASIC) , a field-programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting, individually or collectively, a means for performing the functions described in the present disclosure.

A general-purpose processor may be a microprocessor but, in the alternative, the processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration) . Any functions or operations described herein as being capable of being performed by a processor may be performed by multiple processors that, individually or collectively, are capable of performing the described functions or operations.
[0300] The functions described herein may be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functions may be stored as or transmitted using one or more instructions or code of a computer-readable medium. Other examples and implementations are within the scope of the disclosure and appended claims. For example, due to the nature of software, functions described herein may be implemented using software executed by a processor, hardware, firmware, hardwiring, or combinations of any of these. Features implementing functions may also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations.
[0301] Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one location to another. A non-transitory storage medium may be any available medium that may be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM) , flash memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) , or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium.

[0302] As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” ) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C) . Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. ”
[0303] As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” and “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components, ” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ”
[0304] The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database, or another data structure) , ascertaining, and the like. Also, “determining” can include receiving (e.g., receiving information) , accessing (e.g., accessing data stored in memory) , and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.
[0305] In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label or other subsequent reference label.
[0306] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration” and not “preferred” or “advantageous over other examples. ” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some figures, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
[0307] The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
