Description

Paging configuration for receiving downlink data Technical Field

[0001] This manual relates to wireless communication. Background Technology

[0002] A communication system can be a facility that enables communication between two or more nodes or devices (such as fixed or mobile communication devices). Signals can be carried on wired or wireless carriers.

[0003] An example of a cellular communication system is the architecture standardized by the 3rd Generation Partnership Project (3GPP). The latest developments in this field are often referred to as Long Term Evolution (LTE) of Universal Mobile Telecommunications System (UMTS) radio access technology. EUTRA (Evolved UMTS Terrestrial Radio Access) is the air interface for the 3GPP LTE upgrade path for mobile networks. In LTE, base stations or access points (APs) called enhanced node APs (eNBs) provide radio access within a coverage area or cell. In LTE, mobile devices or mobile stations are called User Equipment (UEs). LTE has incorporated many improvements and developments. All aspects of LTE are constantly being improved.

[0004] The development of 5G New Radio (NR) is part of an ongoing evolution of mobile broadband to meet the requirements of 5G, similar to the early evolution of 3G and 4G wireless networks. Furthermore, 5G targets emerging use cases beyond mobile broadband. The goal of 5G is to deliver significant improvements in wireless performance, which can include new levels of data rates, latency, reliability, and security. 5G NR can also scale to efficiently connect massive Internet of Things (IoT) networks and can provide new mission-critical services. For example, ultra-reliable and low-latency communication (URLLC) devices may require high reliability and extremely low latency. 6G and other networks are also under development.

[0033] It should be understood that although the preceding terms such as “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another and do not restrict the order of the (multiple) nouns. For example, without departing from the scope of the exemplary embodiments, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element. As used herein, the term “and / or” includes any and all combinations of one or more of the listed terms.

[0034] As used herein, unless explicitly stated otherwise, “in response to A” does not indicate that the step is performed immediately after “A” occurs, and one or more intermediate steps may be included.

[0035] Figure 1 is a block diagram of a wireless network 130. In the wireless network 130 of Figure 1, user equipment 131, 132, 133, and 135 (also referred to as mobile stations (MS) or user equipment (UE)) can connect to (and communicate with) a base station (BS) 134, which can also be referred to as an access point (AP), an enhanced node B (eNB), a gNB, or a network node. The terms user equipment and user equipment (UE) are used interchangeably. The BS can also include or be referred to as a RAN (Radio Access Network) node, and can include a portion of the BS or a portion of the RAN node, such as (e.g., a centralized unit (CU) and / or a distributed unit (DU) in the case of splitting the BS or splitting the gNB). At least a portion of the functionality of the BS (e.g., the access point (AP), base station (BS), or (e) node B (eNB), gNB, RAN node) can also be performed by any node, server, or host that can be operatively coupled to a transceiver (such as a remote radio head end). BS (or AP) 134 provides wireless coverage within cell 136, including to user equipment (or UEs) 131, 132, 133, and 135. Although only four user equipment (or UEs) are shown connected to or attached to BS 134, any number of user equipment can be provided. BS 134 is also connected to core network 150 via S1 interface 151. This is just a simplified example of a wireless network, and other wireless networks can be used.

[0036] A base station (e.g., such as BS 134) is an example of a radio access network (RAN) node within a wireless network. A BS (or RAN node) can be or can include (or may alternatively be referred to as), for example, an access point (AP), a gNB, an eNB, or portions thereof (such as a centralized unit (CU) and / or a distributed unit (DU) in the case of a split BS or a split gNB), or other network nodes.

[0037] Some functions of a communication network can be performed, at least partially, in a central / centralized unit (CU) (e.g., a server, host, or node), which is operatively coupled to distributed units (DUs) (e.g., radio headends / nodes). Therefore, 5G network architectures can be based on a so-called CU-DU split. A gNB-CU (central node) can control multiple spatially separated gNB-DUs to at least act as transmit / receive (Tx / Rx) nodes. However, in some embodiments, a gNB-DU (also referred to as a DU) can include, for example, a Radio Link Control (RLC), Media Access Control (MAC) layer, and a Physical (PHY) layer, while a gNB-CU (also referred to as a CU) can include layers above the RLC layer, such as the Packet Data Convergence Protocol (PDCP) layer, Radio Resource Control (RRC), and Internet Protocol (IP) layer. Other functional splits are also possible.

[0038] According to illustrative examples, a BS node (e.g., BS, eNB, gNB, CU / DU, etc.) or radio access network (RAN) can be part of a mobile telecommunications system. The RAN (radio access network) can include one or more BS or RAN nodes implementing radio access technologies, for example, to allow one or more UEs to access the network or core network (CN). Therefore, for example, the RAN (RAN node, such as BS or gNB) can reside between one or more user equipments or UEs and the core network. According to example embodiments, each RAN node (e.g., BS, eNB, gNB, CU / DU, etc.) or BS can provide one or more wireless communication services for one or more UEs or user equipments, for example, to allow UEs to wirelessly access the network via the RAN node. Each RAN node or BS can perform or provide wireless communication services, such as allowing a UE or user equipment to establish a wireless connection to the RAN node, and sending and / or receiving data from one or more UEs. For example, after establishing a connection to a UE, the RAN node or network node (e.g., BS, eNB, gNB, CU / DU, etc.) can forward data received from the network or core network to the UE, and / or forward data received from the UE to the network or core network. RAN nodes or network nodes (e.g., BS, eNB, gNB, CU / DU, etc.) can perform a variety of other radio functions or services, such as broadcasting control information to UEs (e.g., system information or on-demand system information), paging UEs when data to be delivered to them is available, assisting UEs in handover between cells, scheduling resources for uplink data transmission from (multiple) UEs and downlink data transmission to (multiple) UEs, and issuing control information to configure one or more UEs. These are some examples of one or more functions that a RAN node or BS can perform.

[0039] User equipment or user nodes (user terminals, user equipment (UE), mobile terminals, handheld wireless devices, etc.) can refer to portable computing devices, including wireless mobile communication devices operating with or without a subscriber identification module (SIM). Examples include, but are not limited to, devices of the following types: mobile station (MS), mobile phone, cell phone, smartphone, personal digital assistant (PDA), handset, device using a wireless modem (alarm or measuring device, etc.), laptop and / or touchscreen computer, tablet computer, tablet phone, game console, laptop, vehicle, sensor, and multimedia device, or any other wireless device. It should be understood that user equipment can also be (or may include) a virtually exclusive uplink-only device, an example of which is a camera or camcorder that loads image or video clips onto the network. Furthermore, user nodes can include user equipment (UE), user equipment, user terminal, mobile terminal, mobile station, mobile node, subscriber equipment, subscriber node, subscriber terminal, or other user nodes. For example, a user node can be used to wirelessly communicate with one or more network nodes (e.g., gNB, eNB, BS, AP, CU, DU, CU / DU) and / or with one or more other user nodes, regardless of the technology or radio access technology (RAT). In LTE (as an illustrative example), the core network 150 can be referred to as the evolved packet core (EPC), which may include: a mobility management entity (MME) that can handle or assist user equipment mobility / handover between BSs; one or more gateways that can forward data and control signals between the BS and a packet data network or the Internet; and other control functions or blocks. Other types of wireless networks (such as 5G, which may be referred to as New Radio (NR)) may also include a core network.

[0040] Furthermore, the technologies described in this paper can be applied to various types of user equipment or data service types, or to user equipment that can have multiple applications running on it, which can be different data service types. New 5G (NR) development can support many different applications or many different data service types, such as, for example: Machine-Type Communication (MTC), Enhanced Machine-Type Communication (eMTC), Internet of Things (IoT), and / or Narrowband IoT user equipment, Enhanced Mobile Broadband (eMBB), and Ultra-Reliable Low-Latency Communication (URLLC). Many of these new 5G (NR) related applications may typically require higher performance than previous wireless networks.

[0041] The Internet of Things (IoT) can refer to a growing group of objects that possess internet or network connectivity, enabling them to send and receive information from other network devices. For example, many sensor-type applications or devices can monitor physical conditions or states and send reports to servers or other network devices, such as when an event occurs. Machine-type communication (MTC or machine-to-machine communication), for instance, can be characterized by fully automated data generation, exchange, processing, and driving between intelligent machines, with or without human intervention. Enhanced Mobile Broadband (eMBB) can support higher data rates than currently available in LTE.

[0042] Ultra-Reliable and Low-Latency Communication (URLLC) is a new type of data service or new use case that can be supported for new radio (5G) systems. This enables emerging new applications and services such as industrial automation, autonomous driving, vehicle safety, and e-health services. Through illustrative examples, 3GPP aims to provide [services] with [capabilities] comparable to 10 [other technologies]. -5 The block error rate (BLER) and U-plane (user / data plane) latency of up to 1 ms correspond to reliable connectivity. Therefore, for example, URLLC user equipment / UEs may require significantly lower block error rates and lower latency (with or without simultaneous high reliability requirements) than other types of user equipment / UEs. Thus, for example, URLLC UEs (or URLLC applications on UEs) may require shorter latency compared to eMBB UEs (or eMBB applications running on UEs).

[0043] The technologies described in this document can be applied to a variety of wireless technologies or wireless networks, such as 5G (New Radio (NR)), cmWave, and / or mmWave band networks, IoT, MTC, eMTC, eMBB, URLLC, 6G, and any other wireless network or wireless technology. These example networks, technologies, or data service types are provided as illustrative examples only.

[0044] User equipment (UE) can measure various signals and send one or more measurement reports to the network. For example, a UE can measure reference signals received from one or more network nodes (e.g., gNB or DU), including: Channel State Information Reference Signal (CSI-RS), and / or Synchronization Signal Block (SSB) reference signal, demodulation reference signal, and / or other reference signals. Based on the received reference signals, the UE can measure various signal parameters, such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal-to-Interference-plus-Noise Ratio (SINR), Received Signal Strength Indicator (RSSI), or other signal parameters.

[0045] The PHY (Physical) layer can refer to Layer 1 (L1), and the MAC (Media Access Control) layer can refer to Layer 2 (L2). RSRP, RSRQ, SINR, and RSSI are semaphores measured at Layer 1 (L1). The UE can send L1 measurement reports (e.g., CSI-RS reports, which include measurements of one or more signal parameters for one or more cells) to the gNB, source DU, or serving cell. These L1 measurement reports can be sent periodically, for example, or aperiodically. L1 / L2 measurement reports may not include averaging or filtering of the measurements, or may include less averaging or filtering than performed for L3 measurement reports. L1 (or L1 / L2) measurement reports can be sent by the UE to the serving network node or source DU, and can cause the network node to trigger or initiate an L1 / L2 triggered mobility (LTM) handover of the UE to another cell. L1 measurements (e.g., RSRP, RSRQ, RSSI) can be periodically provided or reported to the DU (MAC / PHY).

[0046] In the example, the Sound Reference Signal (SRS) transmission and the Non-Zero Power (NZP)-CSI-RS measurement can be used to assess channel quality, perform measurements related to beam management and mobility, etc. For example, CSI components may include at least one of the following: Channel Quality Information (CQI), Precoding Matrix Indicator (PMI), CSI-RS Resource Indicator (CRI), Synchronization Signal SS / PBCH Resource Block Indicator (SSBRI), Layer Indicator (LI), Rank Indicator (RI), L1-RRSP, etc.

[0047] The configured NZP-CSI-RS resource can correspond to up to 32 NZP-CS6-RS antenna ports in the NR. For example, up to 32 different antenna ports can be multiplexed in time and frequency across the entire CSI-RS resource.

[0048] In wireless communication, an antenna port can represent a unique logical interface through which signals can be transmitted or received by a physical antenna or a group of antennas. For 5G NR, the use of different antenna ports enables various transmission and reception scenarios, allowing advanced functions such as beamforming and MIMO (Multiple-Input Multiple-Output).

[0049] In the example, the UE can use antenna ports associated with reference signal resources(s) for channel estimation and determination of relevant channel state information (CSI) for downlink transmissions. In other words, each individual downlink transmission of a reference signal or channel can be performed using a specific antenna port whose identifier is known to the UE.

[0050] In the example, the structure in the antenna port numbering can be used so that antenna ports used for different purposes have different ranges of numbers. For example, downlink antenna ports starting with 1000 can be used for PDSCH. Different transport layers for PDSCH can use antenna ports in this series; for example, 1000 and 1001 can be used for two-layer PDSCH transmission. In the example, downlink antenna ports in the 3000 series can be used for CSI-RS.

[0051] In example embodiments, the Internet of Things (IoT) can refer to the interconnection and autonomous exchange of data between devices. Three main categories of IoT can include large-scale IoT, critical IoT, and broadband IoT. For example, large-scale IoT can be deployed in applications such as smart meters, asset tracking and management, fleet management, sensors, remote monitoring, smart cities, etc. In cellular systems, large-scale IoT deployments can be supported via low-power wide-area networks (LPWA). In 4G LTE, LPWA networks based on NB-IoT and LTE-M technologies have been introduced. LPWA features include: low device complexity / cost, low device power consumption enabling battery life exceeding 10 years, enhanced coverage compared to broadband services (up to 20-25 dB of enhanced coverage), support for a large number of devices, latency-tolerant data transmission, and infrequent data transmission.

[0052] In the example, when the cell no longer supports broadband service, the UE can switch from a broadband carrier or bandwidth portion (BWP) to an LPWA carrier (or narrowband carrier) or BWP.

[0053] Figure 2A illustrates LPWA as a fallback carrier or BWP for a broadband UE. In this example, the enhanced mobile broadband (eMBB) carrier is separated from the LPWA carrier.

[0054] Figure 2B illustrates an in-band to eMBB carrier LPWA deployment. In this example, the LPWA carrier can be deployed within the eMBB carrier's band. This allows for efficient spectrum utilization, particularly in the early stages of LPWA deployment, where there may not be a large number of LPWA devices (IoT UEs) in the system.

[0055] In the example, LPWA carriers / cells can have significantly enhanced coverage compared to eMBB carriers. To efficiently support the UE under various radio link coverage conditions, LPWA cells can support multiple coverage enhancement (CE) levels. This then allows the UE to access the cell at the appropriate coverage enhancement level. For example, LTE-M and NB-IoT can support up to three different CE levels configured by the network. Table 1 shows an example of CE level configuration by the network based on the maximum coupling loss (MCL) determined by the UE according to RSRP measurements. In the example shown in Table 1, CE0 can be used by the UE in normal coverage (e.g., a UE with an RSRP measurement above the configured threshold). CE1 can be used by a UE requiring up to 10 dB of coverage enhancement from normal coverage, while CE2 can be used by a UE requiring 10 dB to 20 dB of coverage enhancement. For each CE level, the network can be configured with different resources (e.g., time-frequency resources for the Physical Random Access Channel (PRACH) and Physical Downlink Control Channel (PDCCH), different maximum repetition counts (e.g., for PRACH, Physical Uplink Shared Channel (PUSCH), PDCCH, and Physical Downlink Shared Channel (PDSCH)), and different radio configurations (e.g., modulation and coding scheme (MCS) table, resource allocation scheme, modulation scheme, retransmission count, etc.). Table 1. CE modes configured by the network.

[0056] In the example, to receive a paging or paging opportunity (PO), a UE may need to wake up before the PO (e.g., during the next DRX activation period) to read 1-3 SSB bursts before the PO to ensure time-frequency synchronization with the network (in order to prepare for decoding paging records in the downlink data channel, such as, for example, PDSCH). Additionally, if many UEs share the same PO (e.g., read the same paging DCI), the rate of false paging alarms may increase. For example, most UEs in the PO may not be able to find their UE_ID in the paging record. These factors can lead to wasted energy for UEs monitoring paging within the cell.

[0057] In the example, the Early Paging Indication (PEI) mechanism can be employed.

[0058] Figure 3 is a diagram illustrating an example of Early Paging Indication (PEI). To address the issue of waking up before paging, an Early Paging Indication (PEI) mechanism can be employed. The PEI can act as a Wake-Up Signal (WUS), which can pre-indicate whether a UE subgroup needs to be paged. Therefore, a UE can wake up only if its subgroup is indicated in the PEI to synchronize and monitor the Page Entity (PO). In the example, the PEI can be transmitted in DCI format 2_7 and can be configured for up to eight UE subgroups per PO.

[0059] In the example, the wake-up receiver (WUR) can be a low-power receiver designed to detect the WUS and only wake the master receiver (MR) from a low-power state to monitor the PO when necessary. Therefore, the implementation of the WUS can enhance energy efficiency.

[0060] In the example, low-power WUS (LP-WUS) operation of the UE in RRC-IDLE or RRC-INACTIVE modes can be supported.

[0061] Figure 4 illustrates an example operation of LP-WUS. In the example, low-power WUS (LP-WUS) operation in RRC-IDLE / INACTIVE mode may include the following. In the example, UEs monitoring the same PO can be divided into multiple subgroups, where LP-WUS can provide a wake-up indication for each subgroup. In the example, the following options may be applicable.

[0062] As shown in Figure 4, Option 1 describes that UEs monitoring the same PO can monitor the same LP-WUS timing (LO).

[0063] As shown in Figure 4, option 2 describes that UEs corresponding to different POs can monitor the same LO.

[0064] As shown in Figure 4, option 3 describes that UEs monitoring the same PO can be divided into multiple subgroups, where UEs in each subgroup can monitor the same LO.

[0065] In another example shown in Figure 4, a combination of the above options can be achieved.

[0066] In the example implementation, a priority access mode can be employed. Priority access mode allows the UE to perform faster (lower latency / delay) initial access based on the priority of the UE's services.

[0067] Figure 5 illustrates priority access for LPWA. In the example, the UE can be configured with at least two access configurations: one for priority access and another for normal access. The UE can select priority access in the event of priority data transmission, and then the UE can send a priority indication to the gNB via a random access message (e.g., with a preamble). In response to sending the priority indication, the UE can monitor the control channel and use the priority access configuration to perform the remaining random access steps, for example, by using a higher bandwidth control resource set (CORESET) and bandwidth portion (BWP) to receive subsequent messages such as RAR, RRC messages, and / or Msg2 / MsgB / Msg4.

[0068] In the example, the network might determine to minimize resource usage for LPWA (e.g., prioritizing eMBB services) and conserve UE battery life (e.g., configuring the UE to have a small coreset size and infrequent control channel monitoring). Doing so can increase latency. Therefore, problems may arise when certain IoT message (or data) types, such as critical alarms, fault reports, emergency reports, remote commands, etc., require low-latency transmission.

[0069] In existing technologies, IoT services can be treated equally. For example, existing paging procedures do not allow for prioritizing delay-sensitive / critical data transmission. In an example, when a UE receives a paging request, it can determine whether to establish or restore a connection. The UE can then indicate a reason during RRC connection establishment (or restoration) to indicate priority. In an example, the UE can establish / restore an RRC connection with an access identifier to indicate a priority request. However, high-priority services are not treated differently from ordinary services during the paging process. As a result, the UE can decode the paging, and based on the paging reason, the UE can execute the appropriate procedure for priority access / connection. However, in cases of delay-critical data transmission, data transmission may not be performed within the required delay threshold. In an example, data transmission may include transmissions of critical IoT services, Small Data Transmission (SDT), Early Data Transmission (EDT), procedures(s) for transmissions of infrequent small packets (e.g., 100 bytes), etc. Therefore, when delay-sensitive data transmission is not performed according to delay requirements, performance degradation may occur, and / or the transmitted data may be irrelevant or invalid.

[0070] Therefore, paging methods that prioritize the reception of high-priority data (downlink data) can help ensure that the requirements of delay-sensitive downlink data are met.

[0071] The example embodiments aim to improve paging operation by enhancing the paging configuration so that paging for receiving high-priority data can have a different configuration than paging for ordinary or low-priority data. Additionally or alternatively, the example embodiments may include a method for an enhanced wake-up procedure for receiving downlink (DL) data with a different configuration compared to ordinary data, for example, having greater bandwidth that produces lower latency for priority DL data.

[0072] Therefore, techniques for enhanced paging configurations are provided, enabling the UE to receive high-priority downlink data with lower latency. In an example embodiment, the UE can receive a first paging configuration from a network node (e.g., a base station (BS), a cell of a base station, an eNB, a gNB, a gNB-DU, etc.). In the example, the first paging configuration can be used for receiving paging associated with downlink data. In the example, the downlink data can be associated with a first priority level. For example, the first priority level can be a high priority level, an enhanced priority level, etc. In the example, the first paging configuration can be different from a second paging configuration used for receiving downlink data associated with a second priority level. For example, the second priority level can be a low priority level, a normal priority level, etc. In the example, the UE can receive a wake-up signal (WUS) from the network node indicating that paging for receiving downlink data associated with the first priority level is being monitored based on the first paging configuration. For example, this monitoring can be based on the first paging configuration. In the example, the UE can receive paging for receiving downlink data associated with the first priority level from the network node based on the first paging configuration. In the example, the UE can receive downlink data associated with the first priority level based on the received paging.

[0073] Therefore, when the example embodiments are implemented, the UE can be enabled to wake up in different modes. For example, a UE using higher bandwidth may be able to wake up for receiving priority downlink data (or SDT) with lower latency.

[0074] In the example, the UE can receive information about the mapping between the WUS and the paging configuration. For example, the first WUS can indicate: paging for monitoring the reception of downlink data associated with a first priority level, based on a first paging configuration. As another example, the second WUS can indicate: paging for monitoring the reception of downlink data associated with a second priority level, based on a second paging configuration.

[0075] In the example, the UE can monitor the WUS. In the example, the indications made by the WUS can be based on a single bit indicated by the WUS. For example, a single bit can be conveyed through ON / OFF keying, high / low signal levels, etc.

[0076] In the example, WUS can be associated with an enhanced paging early indication radio network temporary identifier (ePEI-RNTI), which indicates: paging for monitoring the reception of downlink data associated with the first priority level.

[0077] In the example, if the WUS is configured, the UE can monitor the WUS, which can indicate whether to utilize a first (or enhanced) paging configuration to further monitor paging (e.g., monitoring both the control channel (such as, for example, PDCCH) and receiving the corresponding data channel (such as, for example, PDSCH) containing the paging record during paging). Alternatively, regardless of whether the WUS is configured, the PDCCH transmitted by the network in the PO can indicate whether to utilize the first paging configuration to receive the corresponding PDSCH that may include the paging record. In the example, if the WUS indicates whether paging is monitored using the first paging configuration, the indication can be provided by: 1) bits in the payload of the WUS signal indicating the first paging configuration (relative to the second paging configuration) (and possibly for each subgroup of each PO); 2) by association with the RNTI used for the first paging configuration, for example, ePEI-RNTI (relative to the normal PEI-RNTI); 3) by association with a dedicated WUS time-frequency timing of the WUS, which can indicate that paging is monitored using the first paging configuration; 4) by association with a dedicated WUS sequence of the WUS, which indicates that paging is monitored using the first paging configuration.

[0078] In one example, the WUS can instruct the UE to monitor paging for the reception of downlink data associated with a first priority level. For example, this instruction can be associated with a dedicated WUS timing sequence. In another example, the WUS can be associated with a dedicated WUS sequence that instructs the monitoring of paging for the reception of downlink data associated with a first priority level. For example, reception of a paging (or paging message) for the reception of downlink data associated with a first priority level can be based on the reception of a dedicated WUS sequence.

[0079] In the example, the first paging configuration may differ from the second paging configuration. In the example, the first paging configuration may include at least one of the following: first configuration information for the paging control channel (PCCH), first information for the paging timing, first information for the paging frame, first configuration of the control channel for scheduling data channels carrying paging messages, first configuration of the data channel, first configuration of the random access channel (RACH), first configuration of the bandwidth portion (BWP), first configuration of the control resource set (CORESET), first information for the discontinuous reception (DRX) period, first information for the search space, first information for the paging radio network temporary identifier (P-RNTI), first information for synchronization parameters, etc.

[0080] In the example, the second paging configuration (different from the first paging configuration) may include at least one of the following: second configuration information of the paging control channel (PCCH), second information of the paging timing, second information of the paging frame, second configuration of the control channel for scheduling the data channel carrying the paging, second configuration of the data channel, second configuration of the random access channel (RACH), second configuration of the bandwidth portion (BWP), second configuration of the control resource set (CORESET), second information of the discontinuous reception (DRX) period, second information of the search space, second information of the paging radio network temporary identifier (P-RNTI), second information of the synchronization parameters, etc.

[0081] In an example embodiment, the first paging configuration and the second paging configuration may be associated with the same paging control channel (PCCH) having the same paging timing (PO) and paging frame (PF).

[0082] In an example embodiment, the UE may receive information indicating a validity period associated with at least one of a first paging configuration or a second paging configuration. In another example, the UE may receive information indicating a validity condition associated with at least one of a first paging configuration or a second paging configuration. For example, the validity condition may be based on at least one of the UE's battery level and the UE's mobility state / condition.

[0083] In the example, the first paging configuration can be used (or associated with) for enhanced paging of downlink data reception. The downlink data can be associated with a first priority level. In the example, the second paging configuration can be used for normal paging of downlink data reception associated with a second priority level. For example, enhanced paging can have a higher bandwidth than normal paging associated with the second paging configuration. In the example, the paging timing of enhanced paging can be associated with a higher bandwidth than normal paging timing. In the example, the periodicity of enhanced paging can be shorter than the periodicity of normal paging. In another example, the time period of enhanced paging can be shorter than the time period of normal paging. In the example, enhanced paging can use a larger downlink bandwidth portion (BWP) than normal paging.

[0084] In the example, the UE can receive a first paging configuration or a second paging configuration from the network node via at least one of the following: System Information Block (SIB), Radio Resource Control (RRC) message, etc. For example, the SIB can be sent via broadcast, multicast, unicast, etc.

[0085] In the example, a first priority level (or an enhanced priority level) may include at least one of the following: a priority level associated with a queuing policy that has lower queuing delay, a priority level associated with a bandwidth allocation policy that results in lower transmission delay, a priority level associated with time-sensitive communication (TSC), a high priority level, an integer-value-based priority level (e.g., a lower integer value indicates a higher priority level), etc. In the example, a second priority level may include at least one of the following: a low priority level, a priority level associated with delay-tolerant communication, etc.

[0086] In the example, the UE may perform a random access procedure for priority access (e.g., based on receiving a paging for the reception of downlink data associated with a first priority level, such as an enhanced paging). In the example, priority access may include selecting a priority access configuration in response to receiving a paging for the reception of downlink data associated with a first priority level. In the example, the UE may send a random access message to a network node, which includes an indication of selecting a priority access configuration. In the example, the UE may monitor the physical downlink control channel at least in part based on the priority access configuration.

[0087] In the example, the UE can receive a paging from a network node. In the example, receiving a paging may include receiving a control channel based on a first paging configuration. For example, the control channel may schedule a data channel carrying a paging or paging message for receiving downlink data associated with a first priority level. In the example, receiving a paging (or paging message) may include receiving a data channel based on a first paging configuration.

[0088] In the example, the control channel may include: an indication of whether downlink control information (DCI) corresponds to a data channel scheduled for enhanced paging, and an indication of whether the data channel is monitored for normal paging or enhanced paging. In the example, enhanced paging may include: paging for receiving downlink data associated with a first priority level. In the example, normal paging may include: paging for receiving downlink data associated with a second priority level.

[0089] In the example, the indication (e.g., by WUS) may include at least one of the following: a single bit, a cyclic redundancy check (CRC) scrambled with an enhanced paging RNTI (eP-RNTI), or a P-RNTI associated with enhanced paging or normal paging. Regardless of whether WUS is configured, the indication of the first paging configuration can be provided in the PDCCH transmitted in the PO. This indication can be provided by a bit in the PDCCH indicating whether the DCI corresponds to a PDSCH scheduled using the enhanced paging configuration. The indication can also be provided by scrambling the CRC of the PDCCH with a new enhanced paging RNTI (e.g., eP-RNTI) such that if the PDCCH is successfully decoded using that RNTI, the DCI corresponds to a PDSCH scheduled using the first paging configuration.

[0090] In the example, the UE can send a capability indication for enhanced paging support for receiving downlink data associated with a first priority level to a network node or gNB. In this example, the first priority level can be an enhanced priority level, and the second priority level can be a normal priority level. The UE can send the capability indication to the network (e.g., gNB, BS, core network node, etc.) via RRC messages, Non-Access Stratum (NAS) messages, etc.

[0091] Figure 6 is a diagram illustrating aspects of an exemplary embodiment. At 625, UE 610 can receive a Synchronization Signal Block (SSB) from base station (BS) 620. At 630, UE 610 can receive an SIB message or an RRC message from BS 620. In the example, the SIB or RRC message may include a WUS configuration, a first paging configuration (or enhanced paging configuration) for receiving paging associated with downlink data having a first priority level (e.g., an enhanced priority level), a second paging configuration for receiving downlink data associated with a second priority level, etc. At 635, BS 620 can receive high-priority downlink data to be sent to UE 610. At 640, BS 620 can determine to perform enhanced paging. At 645, UE 610 can monitor the WUS, for example, to receive an indication of enhanced paging. At 650, BS 620 may send a WUS with an indication of enhanced paging, for example, an indication to monitor paging for reception of downlink data associated with a first priority level based on a first paging configuration. At 655, in response to this WUS, UE 610 may monitor paging based on the first paging configuration (e.g., enhanced paging configuration). At 660, UE 610 may receive a paging for reception of downlink data associated with a first priority level. At 665, UE 610 may determine to perform priority access. UE 610 may perform a random access procedure for priority access. At 670, UE 610 may send one or more RRC messages to establish or restore an RRC connection. At 675, BS 620 may receive a random access request with an indication of priority access from UE 610. At 680, UE 610 may receive (high) priority downlink data (or SDT) from BS 620.

[0092] Figure 7 is an example of a timeline illustrating the use of a first (enhanced) paging configuration triggered by a wake-up signal. As shown, the timeline example indicates a reduction in latency when the enhanced paging configuration is applied in response to a WUS indication. For example, the latency reduction can be achieved through faster paging PDCCH and paging record (PR) reception (e.g., through higher bandwidth), and additional reduction can be provided by enabling the UE to use a priority access configuration to restore / request a connection.

[0093] The example embodiments also point to enhancements to the control channel for receiving paging messages associated with high-priority downlink data. In the example embodiments, the UE may receive a first paging configuration from a network node (e.g., gNB, BS, eNB, gNB-DU, etc.) for receiving paging messages associated with downlink data. In the example, the downlink data may be associated with a first priority level (e.g., a high priority level or an enhanced priority level). In the example, the first paging configuration may differ from a second paging configuration for receiving downlink data associated with a second priority level. In the example, the second priority level may be a low priority level or a normal priority level. In the example, the UE may receive a control channel from the network node. In the example, the control channel may schedule a data channel that can carry a paging or paging message for receiving downlink data associated with a first priority level. In the example, the control channel may include an indication in the paging message for receiving downlink data with a first priority level. In the example, the UE may receive a data channel from the network node, for example, based on the first paging configuration. In the example, the UE may receive downlink data associated with a first priority level from the network node based on the received paging message (or paging).

[0094] Therefore, when the example implementation is implemented, the UE can be enabled to use different paging configurations based on the priority of the downlink data. For example, a UE with higher bandwidth may be able to wake up to receive downlink data (or SDT) with a (high) priority level and lower latency.

[0095] In the example, the first paging configuration may differ from the second paging configuration. In the example, the first paging configuration may include at least one of the following: first configuration information for the paging control channel (PCCH), first information for the paging timing, first information for the paging frame, first configuration of the control channel for scheduling data channels carrying paging messages, first configuration of the data channel, first configuration of the random access channel (RACH), first configuration of the bandwidth portion (BWP), first configuration of the control resource set (CORESET), first information for the discontinuous reception (DRX) period, first information for the search space, first information for the paging radio network temporary identifier (P-RNTI), first information for synchronization parameters, etc.

[0096] In one example, the second paging configuration (which may differ from the first paging configuration) may include at least one of the following: second configuration information for the paging control channel (PCCH), second information for the paging timing, second information for the paging frame, second configuration for the control channel that schedules the data channel carrying the paging message, second configuration for the data channel, second configuration for the random access channel (RACH), second configuration for the bandwidth portion (BWP), second configuration for the control resource set (CORESET), second information for the discontinuous reception (DRX) period, second information for the search space, second information for the paging radio network temporary identifier (P-RNTI), second information for the synchronization parameters, etc.

[0097] In the example, the first paging configuration and the second paging configuration can be associated with the same paging control channel (PCCH) having the same paging timing and paging frame.

[0098] In the example, the control channel for scheduling the data channel may include a PDCCH, which may include an indication of whether the PDSCH used for normal paging is being monitored or the PDSCH used for enhanced paging is being monitored. For example, the indication may be at least one of the following: a single bit, a P-RNTI associated with enhanced paging or normal paging, etc. In the example, the PDSCH may include an indication of enhanced paging.

[0099] In the example, the UE can receive information from the network node or gNB indicating a validity period associated with at least one of the first paging configuration or the second paging configuration. In the example, the UE can receive information from the network node or gNB indicating validity conditions associated with at least one of the first paging configuration or the second paging configuration. For example, the validity conditions can be based on at least one of the following: the UE's battery level, the UE's mobility conditions / state, etc.

[0100] In the example, the first paging configuration can be used (or associated with it) for enhanced paging of downlink data received with a first priority level (or enhanced priority level). In the example, the second paging configuration can be used for normal paging of downlink data received with a second priority level. For example, enhanced paging can have a higher bandwidth than normal paging associated with the second paging configuration. In the example, the paging timing of enhanced paging can be associated with a higher bandwidth than normal paging timing. In another example, the periodicity of enhanced paging can be shorter than that of normal paging. In the example, the time period of enhanced paging can be shorter than that of normal paging. In the example, enhanced paging uses a larger downlink bandwidth portion (BWP) than normal paging.

[0101] In the example, the UE may receive a first paging configuration or a second paging configuration from the network node via at least one of the System Information Block (SIB), Radio Resource Control (RRC) messages, etc.

[0102] In the example, a first priority level (or an enhanced priority level) may include at least one of the following: a priority level associated with a queuing strategy having lower queuing delay, a priority level associated with a bandwidth allocation strategy resulting in lower transmission delay, a priority level associated with time-sensitive communication (TSC), a high priority level, an integer-value-based priority level (e.g., a lower integer value can indicate a higher priority level), etc. In the example, a second priority level may include at least one of the following: a low priority level, a priority level associated with delay-tolerant communication, etc.

[0103] In the example, the UE may perform a random access procedure for priority access. In the example, priority access may include at least one of the following: in response to receiving a paging for receiving downlink data associated with a first priority level, selecting a priority level access configuration, sending a random access message to a network node that may include an indication of selecting the priority level access configuration, or monitoring the physical downlink control channel based at least in part on the priority level access configuration.

[0104] In the example, the UE can send a capability indication for enhanced paging support for receiving high-priority downlink data to the network node. The UE can send the capability indication to the network node (such as a gNB (or core network node)) via RRC messages, Non-Access Stratum (NAS) messages, etc.

[0105] In this example, the control channel may include the Physical Downlink Control Channel (PDCCH). In this example, the data channel may be the Physical Downlink Shared Channel (PDSCH).

[0106] In the example, the first priority level can be an enhanced priority level, and the second priority level can be a normal priority level.

[0107] Figure 8 is a diagram illustrating aspects of an exemplary embodiment. At 825, UE 610 can receive an SSB from BS 620. At 830, the BS can configure an enhanced paging configuration or a first paging configuration for UE 610 via the SSB (or via RRC when UE 610 is connected, for example, in an RRC-CONNECTED state). At 835, BS 620 can receive high-priority downlink data to be sent to UE 610. At 840, BS 620 can select a first (or enhanced) paging configuration in response to receiving high-priority data for UE 610. At 845, UE 610 can monitor the paging PDCCH (or paging record) for example, to receive an indication of enhanced paging. At 850, BS 620 can send an indication to UE 610 via the paging PDCCH (or paging record PDSCH) to notify it that an enhanced paging configuration (e.g., the first paging configuration) has been selected. BS 620 can send paging messages according to the enhanced paging configuration. At 855, UE 610 can perform priority access by sending a random access request with a priority access indication. At 860, UE 610 can send an RRC message to establish or restore an RRC connection for priority access. At 865, BS 620 can receive random access requests with priority access indications from UE 610 and can send RAR, RRC messages, etc. to UE 610. At 870, BS 620 can send downlink data (or SDT) to UE 610 based on priority access.

[0108] In example embodiments, the UE can be configured with at least a first paging configuration or an enhanced paging configuration (e.g., in addition to a normal paging configuration). An enhanced paging configuration can be used to trigger the exchange (or reception) of high-priority data, while a normal paging configuration can be used for the exchange (or reception) of normal data. An enhanced paging configuration can be defined using a single PCCH configuration (e.g., a common paging frame (PF) / PO for enhanced or normal paging), but can be defined using different PDCCH / PDSC / RACH configurations compared to normal paging. Alternatively, the enhanced paging configuration can use a different PF / PO timing than normal paging, where normal paging can follow a different DRX cycle, and in this case, the UE can be at the PO timing indicated by the WUS wake-up signal. In the example, the enhanced paging configuration can have a different PDCCH configuration compared to the normal paging configuration (e.g., different CORESET and / or paging search space configurations). For example, an enhanced paging coreset can be broadband and the search space can have a smaller or shorter monitoring period (e.g., monitoring times can be closer to each other in time), while a regular paging coreset can be narrowband and the search space can have a larger monitoring time slot period (e.g., monitoring times can be more dispersed in time).

[0109] Figure 9 is a diagram illustrating aspects of an exemplary embodiment. In the example, the PDCCH configuration of the enhanced paging configuration may be in a different DL BWP configuration than the PDCCH of the normal paging configuration. In an alternative implementation, a single PDCCH configuration may be used for paging, wherein an indication in the PDCCH indicates whether the PDSCH (carrying paging records) is monitored corresponding to either the normal DL BWP / PDSCH configuration (narrowband) or the enhanced DLBWP / PDSCH configuration (wideband). In the example, the indication in the PDCCH may be provided by using spare bits or by using a new P-RNTI for enhanced paging.

[0110] Figure 10 is a diagram illustrating aspects of an example embodiment. In the example, alternative solutions may include implementations based on paging messages / records. For example, fields (e.g., a bit) in the paging record PDSCH may indicate whether an enhanced paging configuration should be selected and / or whether enhanced paging should be performed.

[0111] In the example, the UE may be provided with additional configuration information regarding the procedures required for the UE to receive a paging with an enhanced paging configuration. For example, the additional configuration information may indicate whether the UE needs to perform additional synchronization, or whether synchronization is required on different synchronization resources or different synchronization signals. In the example, the UE may receive configurations for multiple paging configurations from a network node, which may be subject to (or based on) a UE capability indication, whereby the UE may indicate (to the network node) its ability to monitor / support the reception of multiple paging configurations (and PDSCH). The capability indication may include further details about the characteristics of the supported POs and the UE's behavior when monitoring POs. In the example, the network may provide additional information regarding the effectiveness of the enhanced paging configuration. The enhanced paging configuration may be effective for a specific duration, or when the UE is under specific conditions (e.g., battery level, mobility state) or supports (multiple) specific features.

[0112] In the example, if the WUS is configured, the UE can use the enhanced paging configuration to monitor paging in response to receiving a WUS indicating an enhanced paging configuration (e.g., a first paging configuration). In the example, when the WUS is not configured, the UE can unconditionally monitor paging using the enhanced paging configuration, at least during its DRX-ON period. Alternatively, in response to receiving a PDCCH in a PO indicating an enhanced paging configuration (carrying a paging record) for PDSCH, the UE can interpret the DCI as corresponding to an enhanced paging configuration for PDSCH (e.g., an enhanced DL BWP / PDSCH configuration) and can receive the PDSCH accordingly.

[0113] In the example, the network can send a paging message with both an enhanced paging configuration and a normal paging configuration (if available) to improve paging reliability. The UE can use both paging configurations to monitor for potential missed enhanced paging messages, such as due to fading, interference, skipping, etc.

[0114] In the example, if priority access is configured, the UE can perform random access using the priority access configuration in response to receiving a paging with enhanced paging configuration (e.g., the UE can also follow part of the priority access procedure in response to receiving a paging with enhanced paging configuration).

[0115] In the example, the UE can instruct the network node (gNB) to revert to the normal paging and access configuration (e.g., by using a preamble response assigned for normal access indication), for example, if the UE determines to remain in normal BWP / CORESET operation for energy-saving purposes. Therefore, the network node or gNB can determine to use the normal configuration for subsequent RRC message transmissions and data transmissions(s).

[0116] In the example, if the UE cannot successfully perform random access using the priority access configuration after receiving an instruction to receive paging using the enhanced paging configuration, the UE can revert to random access using the normal access configuration.

[0117] In an example implementation, if a UE has moved from its last known cell, it could result in significant delays in reaching the UE in the RAN Notification Area (RNA) because the network might begin paging on the last unknown cell and then extend that paging to other cells. In this example, an enhanced paging configuration can be used by the network to ensure that a UE that has moved to another cell can be woken up with low latency. The network that determines that a UE that has moved to another cell can be paging quickly can send a wake-up indication or WUS to monitor paging with the enhanced paging configuration on a larger cell size (e.g., all cells) within the tracking area. A regular UE not configured with this option can simply be triggered to listen for normal paging. The set of cells where the enhanced paging configuration can be enabled can be exchanged via the Xn interface between gNBs.

[0118] In another example, for network energy conservation, the set of paging beams provided by the network can differ for normal paging configurations and enhanced paging configurations. For instance, when the network triggers paging based on an enhanced paging configuration (e.g., for reduced latency of priority data), the network can paging on multiple / all beams, whereas for a normal paging configuration, the network can paging on the last serving SSB beam, at least until a paging upgrade is required. The recommended SSB beams for enhanced and normal paging can be swapped between the gNB-CU and gNB-DU. When paging is triggered on a beam corresponding to the enhanced paging configuration, the gNB-DU can activate the SSB and / or SIB1 on the beam if the SSB and / or SIB1 on that beam are deactivated to conserve network energy.

[0119] In the example, a single PCCH configuration can exist, for example, a common PF / PO for paging with either an enhanced paging configuration or a normal paging configuration. However, the enhanced paging configuration can have a different PDCCH configuration compared to the normal paging configuration. Therefore, although the PF / PO configuration can be the same, the enhanced paging configuration can enable faster paging PDCCH transmission.

[0120] In another example, different PCCH configurations may exist, such as different PF / POs for paging in an enhanced paging configuration and different PF / POs for paging in a normal paging configuration.

[0121] Figure 11A is a diagram illustrating an example of an enhanced paging configuration triggered by WUS for a UE subgroup. In this example, UEa, UEb, UEc, and UEd can be configured with two paging opportunities, PO1 and PO2, where paging can be provided with a normal paging configuration and an enhanced paging configuration, respectively. The UE can monitor a low-power WUS opportunity (LO), which indicates which PO should be monitored. In response to receiving LO1, the UE can wake up to receive PO1 (e.g., associated with a longer DRX period, using lower bandwidth and longer duration, or in an LPWA BWP), and in response to receiving LO2, the UE can wake up to receive PO2 (e.g., associated with a shorter DRX period, higher bandwidth, shorter duration, or in an eMBB BWP).

[0122] Figure 11B is a diagram illustrating an example of an enhanced paging configuration combined with LP-WUS options for subgroups of UEs. This example embodiment can be applied in conjunction with different LO and PO configuration options. For example, as shown, UEa, UEb, UEc, and UEd (e.g., higher-capability devices with higher QoS services) can be configured to monitor PO1 and PO2 in response to LO1 and LO2, respectively. UEk, UEl, UEm, and UEn are configured to monitor only PO1, for which LO1 provides a wake-up indication. This means that only high-priority UEs are woken up at LO2.

[0123] In another example, the type of WUS used to indicate the enhanced paging configuration can be different from the WUS of a normal paging system (e.g., LP-WUS, group WUS (GWUS), PEI, etc.) and configuration (e.g., periodicity / duty cycle, search space, offset).

[0124] Some examples will now be described based on the descriptions and figures provided in this article.
