[0001] This application claims priority and benefit to GB application number 2402199.0, filed on February 16, 2024, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0002] Various exemplary embodiments of this disclosure generally relate to the field of telecommunications, and more particularly to methods, apparatuses, devices, and computer-readable storage media for dynamic transmission of wake-up signals. Background Technology

[0003] Low-Power Wake-Up Signal (LP-WUS) is being developed for New Radio (NR). One objective is to investigate and evaluate the Layer 1 (L1) procedures and higher-layer protocol changes required to support the wake-up (or wake-up) signal. This research could consider using a separate low-power receiver at the User Equipment (UE) and assess how UE power consumption can be reduced. The intention is that the UE's primary radio or primary receiver (which could be a regular transceiver) could be in sleep mode (or even powered off) to conserve power and activated upon receiving a wake-up signal from the network. For example, the network could trigger UE wake-up in an event-driven manner when needed. The network could transmit a wake-up signal to the UE, which could be monitored by the low-power receiver at the UE. When the UE receives the WUS, the low-power receiver can trigger the primary receiver to wake up and can begin communication via the primary receiver. Otherwise, the primary radio is off or remains in deep sleep mode. The low-power receiver can operate in an always-on mode with very low power consumption. It is expected that the low-power receiver will consume significantly less power compared to a regular transceiver. Summary of the Invention

[0024] As used herein, the term "network device" refers to a node in a communications network through which terminal devices access the network and receive services. Depending on the terminology and technology applied, a network device can refer to a base station (BS) or access point (AP), such as a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), an NR NB (also known as a gNB), a remote radio unit (RRU), a radio header (RH), a remote radio header (RRH), a relay, an integrated access and backhaul (IAB) node, a low-power node (such as a femtosecond or picosecond), a non-terrestrial network (NTN) or non-terrestrial network equipment (such as satellite network equipment), low Earth orbit (LEO) satellites and geostationary Earth orbit (GEO) satellites, spacecraft network equipment, etc. In some example embodiments, the radio access network (RAN) split architecture includes a centralized unit (CU) and a distributed unit (DU) at the IAB donor node. The IAB node includes a mobile terminal (IAB-MT) portion that behaves as a UE toward the parent node, and the DU portion of the IAB node behaves as a base station toward the next-hop IAB node.

[0025] The term "terminal device" refers to any terminal device capable of wireless communication. By way of example and not limitation, a terminal device may also be referred to as a communication device, user equipment (UE), subscriber station (SS), portable subscriber station, mobile station (MS), or access terminal (AT).

[0026] As used herein, the terms “resource,” “transmission resource,” “resource block,” “physical resource block” (PRB), “uplink resource,” or “downlink resource” can refer to any resource used to perform communication, such as communication between a terminal device and a network device, or resources in the time domain, frequency domain, spatial domain, code domain, or any other resource that enables communication.

[0027] As mentioned above, LP-WUS is being developed for NR. LP-WUS is currently considered for use in IDLE and / or INACTIVE modes as well as CONNECTED mode. Current discussions primarily focus on downlink (DL) reception, where LP-WUS can be used to wake up the primary radio to receive the Physical Downlink Control Channel (PDCCH) and / or Physical Downlink Shared Channel (PDSCH), for example, for paging or other data. For both IDLE and / or INACTIVE modes and CONNECTED mode, the following LP-WUS content candidates can be used: information about the user to whom LP-WUS is targeted, such as UE group, UE subgroup, or UE-ID. The above information can be indicated explicitly or implicitly.

[0028] To enable the Low Power Wake-up Receiver (LP-WUR) to maintain synchronization with the cell, the introduction of a Low Power Synchronization Signal (LP-SS) is considered. At least for LP-WURs unable to receive existing Primary Synchronization Signal (PSS) and / or Secondary Synchronization Signal (SSS), a periodic LP-SS signal is beneficial for the following functions, if supported: Radio Resource Management (RRM) measurements by the LP-WUR; at least coarse time synchronization of the LP-WUR; and at least coarse frequency synchronization of the LP-WUR.

[0029] The additional periodic LP-SS system overhead depends on the LP-SS periodicity, system bandwidth (BW), beam and resources required to achieve the target function, etc. If used for coarse synchronization, periodic signals can reduce the overhead of signals preceding LP-WUS (if any). LP-SS can be designed to be common (cell-specific) among UE groups, thus further reducing system overhead. LP-WUR can receive existing PSS and / or SSS, possibly assisted by the Physical Broadcast Channel (PBCH) demodulation reference signal (DMRS) and / or tracking reference signal (TRS), for synchronization. For such an LP-WUR, existing PSS / SSS, possibly assisted by PBCH DMRS / TRS, can be used for the aforementioned functions. The coverage of periodic LP-SS can be equal to or greater than the coverage of LP-WUS. For fine time and frequency synchronization, signals preceding or as part of LP-WUS (e.g., preambles) can be used. If information about activation and deactivation monitored by LP-WUS is carried by the LP-SS, the structure of the LP-SS can be a sequence plus a message with coded bits.

[0030] LP-WUS designs are typically applicable to IDLE and / or INACTIVE modes, as well as CONNECTED modes. The following can be specified: LP-WUS based on on / off keying (OOK) (OOK-1 and / or OOK-4) with an orthogonal frequency division multiplexing (OFDM) sequence superimposed on OOK symbols. Furthermore, the LP-WUS design ensures that the same information is transmitted for IDLE and / or INACTIVE operations, regardless of the LP-WUS type. The OFDM sequence can carry information. Additionally, at least duty cycle monitoring of the LP-WUS is supported.

[0031] For IDLE and / or inactive modes, the LP-WUS procedure and configuration can be specified to indicate paging monitoring triggered by LP-WUS, including at least the configuration, sub-packets, and entry and / or exit conditions for LP-WUS monitoring. The periodicity of LP-WUS can be specified for synchronization and / or RRM of the serving cell. LP-SS in milliseconds. LP-SS is based on OOK-1 and / or OOK-4 waveforms with or without superimposed OFDM sequences. For LP-WURs that can receive existing PSS and / or SSS, the existing PSS and / or SSS can be used for synchronization and RRM instead of LP-SS. For parameters 320ms can be the starting point. In addition, the following can be specified: further RRM relaxation of the UE primary radio (MR) for serving cell measurement and neighboring cell measurement, and UE serving cell RRM measurement offloaded from MR to LP-WUR, including necessary conditions.

[0032] For CONNECTED mode, procedures for UE MR PDCCH monitoring triggered by LP-WUS can be specified, including the activation and deactivation procedures for LP-WUS monitoring. In CONNECTED mode, UE MR deep sleep is not considered, and UERRM and / or Radio Link Monitoring (RLM) and / or Beam Failure Detection (BFD) and / or Side Link Control Information (SCI) measurements are performed by the MR. The target coverage of LP-WUS and LP-SS can be the coverage of the Physical Uplink Shared Channel (PUSCH) for Message 3. Optimization of LP-WUS signal design for idle and / or inactive modes takes precedence over optimization for connected modes.

[0033] In Release-19 (Rel-19), LP-WUS can be used to trigger (traditional) paging monitoring, such as Paging Timing (PO) or Paging Early Indication (PEI). It is expected that by designing a simple signal (e.g., WUS) and using dedicated hardware for its monitoring (which can only receive WUS), it will consume significantly less power compared to NR transceivers.

[0034] Furthermore, sub-packets, similar to those in Release-17 PEI, will be supported to reduce unnecessary MR wake-ups. This is beneficial for operations using low-power radios (LR), as the cost of waking an MR from a lower power state (e.g., power consumption cost) can be high. Frequent MR wake-ups from deep sleep states (where all or most MR functions are disabled) can lead to a significant reduction in power-saving gains. Using sub-packets in POs can reduce unnecessary wake-ups (when paging is not targeted at a given UE), which translates to higher information payload. The number of sub-packets considered is in the range of 4 to 8. Additionally, as in the Release-17 PEI design, more than one PO can be mapped to the same LP-WUS, such that for each PO, a separate bit will exist to trigger paging monitoring.

[0035] In the context of an OOK signal, the number of transitions within a (NR)OFDM symbol (denoted by M, where M represents any positive number) can vary. A higher M (e.g., M=4) can be used under good coverage conditions, while a lower M, such as M=1, can be used to reliably transmit the signal with good coverage. Using a lower M results in a lower data rate for OOK modulation, thus reducing spectral efficiency and increasing the LP-WUS footprint (overhead). For IDLE and / or Inactive mode operation, beam scanning of the LP-WUS is expected to be similar to that of conventional broadcast signals (such as paging and synchronization signal blocks (SSBs)), with the overhead multiplied by the number of SSBs used.

[0036] Therefore, in traditional designs, the channel size needs to be determined based on the worst-case UE scenario. This means that if it is desired to reduce overhead by utilizing low data rate modulation, the information payload will need to be reduced. This will prevent or limit the size of the sub-packets that can be applied with a limited payload.

[0037] Because the signal conditions seen by the primary radio (MR) in a cell vary, not all receivers (LRs) can achieve the same coverage. Therefore, we cannot guarantee that all LRs can receive the specific modulation scheme used for the OOK scheme. Thus, it may be more sensible to dynamically switch the LP-WUS scheme based on the response or detectability from the LR in terms of paging response. As mentioned above, the primary goal of LP-WUS is to achieve power saving at the UE.

[0038] An example embodiment of this disclosure provides a dynamic transmission solution for wake-up signals. In this solution, the wake-up signal is segmented, and a paging monitoring indication for a group can be transmitted in each segment. A device (such as a UE) receives a configuration of the maximum number of segments of the wake-up signal. Furthermore, the device is dynamically indicated using the number of active segments of the wake-up signal. The device detects the associated content of the wake-up signal by considering both the configuration and the indication. In this way, power savings can be achieved, and power consumption can be reduced.

[0039] Figure 1 An example communication environment 100 in which exemplary embodiments of the present disclosure can be implemented is shown. In communication environment 100, a plurality of communication devices, including a first device 110 and a second device 120, can communicate with each other. In some example embodiments, the first device 110 can operate as a terminal device, and the second device 120 can operate as a network device serving the terminal device. The service area of ​​the second device 120 may be referred to as cell 102. In some example embodiments, the first device 110 is operable to implement a smartphone device.

[0040] It should be understood that Figure 1 The number of devices and their connections shown are for illustrative purposes only and do not imply any limitation. Communication environment 100 may include any suitable number of devices configured to implement the exemplary embodiments of this disclosure. Although not shown, it will be understood that one or more additional devices may be located in cell 102, and one or more additional cells served by second device 120 or another device may be deployed in communication environment 100.

[0041] In the following description, for illustrative purposes, some example embodiments are described in which the first device 110 operates as a terminal device and the second device 120 operates as a network device. However, in some example embodiments, the operations described with respect to the terminal device may be implemented at the network device or other devices, and the operations described with respect to the network device may be implemented at the terminal device or other devices.

[0042] In some example embodiments, if the first device 110 is a terminal device and the second device 120 is a network device, the link from the second device 120 to the first device 110 is referred to as a DL, and the link from the first device 110 to the second device 120 is referred to as an uplink (UL). In the DL, the second device 120 is a transmission (TX) device (or transmitter), and the first device 110 is a reception (RX) device (or receiver). In the UL, the first device 110 is a TX device (or transmitter), and the second device 120 is an RX device (or receiver). If both the first device 110 and the second device 120 are terminal devices, the link between the two terminal devices is referred to as a sidelink (SL). In the SL, one of the first device 110 and the second device 120 is a TX device (or transmitter), and the other of the first device 110 and the second device 120 is an RX device (or receiver).

[0043] Communication in communication environment 100 can be implemented according to any suitable communication protocol, including but not limited to cellular communication protocols such as first-generation (1G), second-generation (2G), third-generation (3G), fourth-generation (4G), fifth-generation (5G), and sixth-generation (6G), wireless local network communication protocols such as IEEE 802.11, and / or any other currently known or future-developed protocols. Furthermore, communication can utilize any suitable wireless communication technology, including but not limited to: Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Frequency Division Duplex (FDD), Time Division Duplex (TDD), Multiple-Input Multiple-Output (MIMO), Orthogonal Frequency Division Multiplexing (OFDM), Discrete Fourier Transform Extended OFDM (DFT-s-OFDM), and / or any other currently known or future-developed technologies.

[0044] In various embodiments, the first device 110 is capable of monitoring wake-up signals (such as LP-WUS) and includes a first receiver and a second receiver. The first receiver can monitor LP-WUS and can be a low-power receiver (such as a simple receiver with an envelope detector).

[0045] Figure 2 Example state transitions of a first device 110 according to some example embodiments of the present disclosure are shown. For example... Figure 2As shown, the network triggers the first device 110 to wake up precisely when needed by transmitting a special WUS to the first device 110. This special WUS can be monitored by a dedicated low-power WUS receiver at the first device 110. When the first device 110 receives the WUS, the WUS receiver can trigger the wake-up of the ordinary NR transceiver, and communication can begin. Thus, the ultra-low power receiver wakes up the main radio; otherwise, the main radio is turned off or remains in deep sleep mode.

[0046] Figure 3 Signaling flow 300 of communication according to some embodiments of this disclosure is shown. For discussion purposes, reference will be made to... Figure 1 For example, signaling flow 300 can be discussed by using the first device 110 and the second device 120.

[0047] For better understanding, in Figure 3 In the example, the first device 110 can operate as a terminal device, and the second device 120 can operate as a network device.

[0048] like Figure 3 As shown, the first device 110 receives (310) a configuration indicating the maximum number of segments of the wake-up signal. In some embodiments, the configuration may be received in at least one of RRC signaling, system information (SI), or dedicated signaling.

[0049] In some embodiments, the configuration may include a wake-up signal configuration, and the wake-up signal configuration may also indicate at least one of the following: the size of a segment of the wake-up signal, the activation of at least one dynamic indication of the wake-up signal, or one or more segments of the wake-up signal associated with a paging monitoring indication of the first device 110.

[0050] In one example, the wake-up signal may be LP-WUS. In this example, the first device 110 may determine, based on the LP-WUS configuration, what the LP-WUS associated with the paging monitoring indication (such as PO) of the first device 110 is and what the segments in the LP-WUS are.

[0051] In one example, LP-WUS (as an example of a wake-up signal) can be transmitted in an LP-WUS channel. In one example, the first device 110 may be configured by a higher layer with an LP-WUS channel (via system information (SI) or via dedicated signaling), the LP-WUS channel including at least one of the following: the maximum number of segments, the size of the segments, the presence of dynamic indications for LP-WUS, and the scope of adaptation (in LP-SS and / or in LP-WUS).

[0052] In some example embodiments, the multiple segments may include a group of segments mapped to the first device 110 and carrying the same information. Alternatively, in some embodiments, the multiple segments may include a group of segments mapped to the first device 110 and carrying different portions of information. In some example embodiments, the group of segments may be continuous, interleaved, or permuted.

[0053] In one example, grouped segments can be mapped to the LP-WUS channel sequentially. In other possible implementations, the grouped segments are interleaved and / or permuted, such that segments belonging to different groups are transmitted sequentially. In the example, segments belonging to the same group (carrying the same logical information content) can be configured to carry the same physical layer (ON / OFF) sequence or information symbols as repetition. In other possible implementations, segments can carry different sequences or information symbols, which can be concatenated by the receiver to determine the total sequence or information codeword.

[0054] like Figure 3 As shown, the first device 110 receives (320) an indication (referred to as a first indication) related to the number of active segments of a wake-up signal. In some embodiments, the first indication includes at least one of the following: the number of active segments is equal to the number of segments of the wake-up signal carrying different information, or a divisor of the maximum number is equal to the number of groups of segments of the wake-up signal, one of which is active and carries the same information. In an example, an indication that directly indicates the number of (active) segments ( In other embodiments, it can be in approximate numbers ( Instructions are given in the form of ).

[0055] In one example, when the wake-up signal includes LP-WUS, the first device 110 can be configured (via RRC or SI) with the maximum number of segments in the LP-WUS channel, denoted as And depending on further configuration and / or information, the first device 110 can be dynamically notified of the number of active (actually used) segments (active segments) that can be assumed to carry different or the same information. If the number of active segments is less than the maximum number of segments configured for the LP-WUS channel, the segments are grouped together, and the first device 110 may assume that these segments carry the same logical information content, and the first device 110 may use this information in reception (e.g., treat it as a duplicate). LP-SS or LP-WUS can be used to indicate which segment group belongs to which UE mapping.

[0056] In some example embodiments, the first indication may be carried via at least one of a synchronization signal or a wake-up signal. In some example embodiments, the first indication may be carried in the information field of the LP-SS, or provided by modifying at least a portion of the LP-SS.

[0057] In one embodiment, the LP-SS channel carrying the LP-SS (as an example of a synchronization signal) can be used to indicate to the first device 110 how many segments are assumed to be active in subsequent LP-WUS channels. In some example embodiments, this information can be applied to the LP-SS as an additional information field. In examples, this can be provided by changing the LP-SS signal (such as the sequence used throughout the LP-SS or in some parts of the LP-SS).

[0058] Alternatively or additionally, the first indication may be received via a preamble to a wake-up signal (such as LP-WUS). In one example, information related to the number of active segments is notified to the first device 110 as part of an LP-WUS message. In another example, this may be carried as part of an LP-WUS preamble.

[0059] In some example embodiments, the first device 110 may receive (330) an indication (referred to as a second indication) of one or more segments of a wake-up signal assigned to the first device 110. Based on the second indication, the first device 110 may be indicated which segments are active (as a supplement to or replacement of the number of active segments). Similar to the first indication, the second indication may be transmitted via either or both of a synchronization signal or a wake-up signal.

[0060] In some embodiments, the first device 110 may receive (340) an indication (referred to as a third indication) of the mapping between a group of segments of a wake-up signal and the first device 110. Based on the third indication, the first device 110 may determine which group of segments is associated with itself. Similar to the first indication, the third indication may be transmitted via either or both of a synchronization signal or a wake-up signal.

[0061] In some example embodiments, segments of the wake-up signal may carry paging monitoring indications associated with multiple subgroups of the device. Furthermore, segments of the wake-up signal may include a first information sequence indicating that a first subgroup of the multiple subgroups of the device has been paged, and this first information sequence may differ from a second information sequence indicating that a second subgroup of the multiple subgroups of the device has been paged.

[0062] In one example, when only the number of active segments is notified, the valid sequence of each subgroup of paging monitoring indication (e.g., each PO) is different from the valid sequences from other POs. This is to ensure that when the first device 110 attempts to detect the LP-WUS channel and combine segments, the detection does not result in a false alarm.

[0063] In some embodiments, the wake-up signal segments carry paging monitoring indications associated with multiple subgroups of the device. Furthermore, the wake-up signal segments may include at least one of the following: a sequence of information mapped to a subgroup among the multiple subgroups of the device, or an index of a subgroup among the multiple subgroups of the device.

[0064] In one example, the segment may carry a paging subgroup indication for paging monitoring. In another example, the segment may contain a sequence mapped to a specific subgroup, or information symbols that provide an index to the subgroup.

[0065] After transmitting the configuration and instructions related to the segmentation of the wake-up signal, the second device 120 transmits (360) a wake-up signal comprising multiple segments, carrying content associated with the first device 110, based at least on the configuration and the first instruction. The first device 110 detects (370) the content of the wake-up signal associated with the first device 110, based at least on the configuration and the first instruction.

[0066] In some example embodiments, the content may include a paging monitoring indication associated with the first device 110. In some embodiments, the paging monitoring indication may be associated with a group of devices including the first device 110.

[0067] In some example embodiments, the first device 110 may be configured, or the first device 110 may determine, based on the ID of the first device 110, what codewords in the segment associated with a paging monitoring indication (e.g., PO) the first device 110 needs to monitor.

[0068] In one example, the first device 110 may adapt the detection of a wake-up signal (such as LP-WUS) based on the indicated activity segments. For example, the first device 110 may use additional or repeated information in multiple segments to detect the information content of an LP-WUS channel intended for use by the first device 110 (or for the PO of the first device 110).

[0069] In one example, the first device 110 may have multiple assumptions for detecting LP-WUS channel information, such that the first device 110 may attempt to combine different segments for detecting LP-WUS messages intended for use by the first device 110 (or for the PO of the first device 110).

[0070] In some embodiments, the first device 110 may receive (350) an indication (referred to as a fourth indication) of the number of on and off periods of on-off keying (OOK) modulation during a time period for on-off keying modulation in a segment of the wake-up signal. The first device 110 may then further detect the content of the wake-up signal based on the fourth indication. In some embodiments, the number of on and off periods may be indicated for the segmentation of the wake-up signal or for the wake-up signal itself.

[0071] In one example, the network can indicate (e.g., via LP-SS or LP-WUS preamble) the number of “ON” and “OFF” periods of OOK modulation applied during the NR symbol of OOK modulation in an LP-WUS segment.

[0072] The following will refer to Figures 4 to 7 Describe some example implementation methods.

[0073] Figure 4 An example LP-WUS channel configuration 400 according to some embodiments of the present disclosure is shown.

[0074] like Figure 4 As shown, in some embodiments, as a possible example implementation, the LP-WUS channel can be configured with four segments, such that each segment can be associated with a PO. Each segment can be configured to be 4 bits long, and it can be OOK modulated and Manchester encoded (depending on additional configuration) to produce 8 OOK symbols. The LP-WUS channel can also be configured to use OOK modulation with M=2, such that two transitions can occur within one NR symbol. Each segment can be specified to carry an OOK modulation sequence indicating which subgroups of the PO are paged. For this particular example, it can be assumed that each PO can be divided into two subgroups, and the sequence-based indication can be configured such that there exists a sequence that indicates one subgroup can be paged (triggers UEs belonging to that subgroup to begin paging monitoring using MR), and another sequence that indicates one or more subgroups can be paged (triggers all UEs of the PO to begin paging monitoring using MR), and a sequence that indicates that no subgroup in a given PO is triggered. Furthermore, it can be configured that if the number of active segments is less than a maximum value, consecutive segments can be assumed to carry the same information content.

[0075] Figure 5 An example UE LP-WUS channel detection process 500 based on the number of active segments according to some embodiments of this disclosure is shown.

[0076] In some embodiments, when LP-WUS is transmitted to trigger UE monitoring paging, the network can indicate to the UE (via LP-SS, LP-WUS preamble, or both) the number of active segments in the LP-WUS channel. Based on this information, the UE can adjust its detection of the LP-WUS channel, such as... Figure 5 As shown. For example, if the network indicates the number of active segments. It can be equal to the maximum (configured) number of segments. Or the number of activity segments can be greater than , ( If the network indicates that the number of active segments is one, then the UE uses only the information in the allocated segment for detection. In an alternative example, if the network indicates that the number of active segments can be two, the UE can assume that Seg#1 and Seg#2 carry the same information (similarly, Seg#3 and Seg#4 will carry the same information) and use the information in both segments when detecting its PO-specific information (i.e., whether paging is being monitored). Accordingly, if the network indicates that the number of active segments is one, The UE can then assume that all configured segments carry the same information and use it to detect PO-specific information.

[0077] Figure 6 Examples of possible gNB transport formats according to some embodiments of this disclosure are shown.

[0078] In some embodiments, when the network indicates that the number of active segments may be less than the maximum (configured) number of segments ( When this happens, the UE will try multiple hypotheses, which combine information into a segment assigned by the UE (a segment associated with the PO that the UE may be monitoring), allowing the UE to use information only from its own assigned segment (one hypothesis) and other unused segments ( An additional assumption (which considers information from unused segments). For example... Figure 6 As shown, when LP-WUS is configured with And was instructed to have At that time, there are four possible gNB LP-WUS transmission formats. For example, the UE associated with segment #1 will perform detection assumptions based on segment #1.

[0079] Figure 7 Examples of synchronization sequences for LP-SS according to some embodiments of this disclosure are shown.

[0080] In some embodiments, automatic detection of the M value can be implemented in the first device 110, such as... Figure 7 As shown. The device will assume a maximum M value, and based on the detected and / or decoded sequences, the device can determine the M value to use. Figure 7In this example, a simple non-Manchester encoded sequence can be shown. Any sequence can be used, as long as it is a predefined sequence known to the first device 110.

[0081] Alternatively, in some embodiments, a known synchronization signal (or synchronization sequence) may include several bits to indicate the M value of the following data sequence. The synchronization sequence can be transmitted with M=1, and subsequent sequences will have a changed M value based on the decoding of the data bits.
