In the following, unless explicitly stated, resources in the frequency domain and the time domain will be used as examples of transmission resources for describing some example embodiments of the present disclosure. It should be noted that the example embodiments of the present disclosure are equally applicable to other resources in other domains.

[0001] Figure 1 An example communication environment 100 is shown in which example embodiments of the present disclosure may be implemented. The communication environment 100 includes a first device 110 and a second device 120 that may communicate with each other.

[0002] In the following, for the purpose of explanation, some example embodiments are described as the first device 110 operating as a terminal device and the second device 120 operating as a radio access network device. However, in some example embodiments, the operations described in conjunction with the terminal device may be implemented at a radio access network device or other device, and the operations described in conjunction with the radio access network device may be implemented at a terminal device or other device.

[0003] It should be understood that Figure 1 The number of radio access network devices and terminal devices shown in FIG. 1 is given for illustrative purposes and does not imply any limitation. The communication network 100 may include any suitable number of radio access network devices and terminal devices.

[0004] In some example embodiments, if the first device 110 is a terminal device and the second device 120 is a radio access network device, the link from the second device 120 to the first device 110 is referred to as a downlink (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 transmitting (TX) device (or transmitter), and the first device 110 is a receiving (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).

[0005] The communication in the communication environment 100 can be implemented according to any suitable (multiple) communication protocols, including but not limited to cellular communication protocols of the first generation (1G), the second generation (2G), the third generation (3G), the fourth generation (4G), the fifth generation (5G), the sixth generation (6G), etc., wireless local area network communication protocols such as the Institute of Electrical and Electronics Engineers (IEEE) 802.11, and / or any other protocol currently known or developed in the future. In addition, the 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 multiple access (OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM) and / or any other technology currently known or developed in the future.

[0006] As mentioned above, with the advancement of UE power saving in 5G NR, some UEs / devices are expected to have battery life targets of weeks, months, or even years.

[0007] Additionally, some of the UE types (e.g., sensors, actuators, and wearables) require not only long battery life, but also latency-critical services (e.g., sensors for fire detection and extinguishing, for example). Therefore, solutions such as extended discontinuous reception (DRX) (which allows extending the period during which the UE wakes up to monitor for paging, which in turn reduces average power consumption) are not applicable, as eDRX would result in unacceptable communication latency.

[0008] Therefore, research on LP-WUS has recently been approved to achieve further UE power savings for the above device types and includes the goals listed below. Table 1

[0009] This study will consider the use of a separate Low Power Wake-up Receiver (LP-WUR) at the UE and evaluate how this can reduce UE power consumption. The intention is that the UE's Primary Radio (MR) can be in sleep mode (or even powered off) for power conservation and only activated when a WUS is received from the network.

[0010] Basically, the network triggers the UE to wake up exactly when needed in an event-driven manner by sending a special WUS to the UE, which is monitored by a dedicated LP-WUR at the UE. When the UE receives the WUS, the wake-up receiver (WUR) can trigger the wake-up of the normal NR transceiver and communication can begin.

[0011] Thus, the ultra-low power receiver wakes up the MR, which otherwise shuts down or remains in a deep sleep mode. It is assumed that the LP-WUR can operate in an always-on manner with very low power consumption. In fact, by designing a simple WUS signal and using dedicated hardware that is only capable of receiving WUS for monitoring, it is expected that it will consume significantly less power compared to the NR transceiver.

[0012] Some corresponding protocols stipulate that, at least for LP-WUR and LP-WUR that cannot receive the existing primary synchronization signal (PSS) / secondary synchronization signal (SSS), if supported, periodic low power synchronization signal (LP-SS) signals are beneficial for the radio resource management (RRM) measurements of LP-WUR.

[0013] In addition, for idle / inactive mode, it is to be studied that, if present, the RRM measurements of the serving cell are offloaded to the LP-WUR under certain conditions, and if the RRM measurements in the MR are relaxed, the relaxation of the serving / neighboring cell RRM measurements in the MR is considered and the measurements are performed with a relaxed period.

[0014] Therefore, it may be necessary to discuss LR-based measurements and RRM measurement relaxations in this disclosure.

[0015] According to some example embodiments of the present disclosure, a solution for enhanced LR measurement is provided. In the solution, the second device 120 provides a configuration for reporting LP-WUS measurement at the first device 110 to the first device 110. The configuration may at least indicate information of at least one event associated with the LP-WUS measurement. The first device may perform LP-WUS measurement on the received WUS RS and send a measurement report of the LP-WUS measurement to the second device 120 based on the configuration.

[0016] The disclosed solution enables the LR to perform measurements of LP-WUS / SS / beacon signals to offload the MR for RRM measurements without compromising the reachability and mobility of the UE while still obtaining WUS mode power savings.

[0038] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0039] Figure 2 A signaling diagram 200 for enhanced LR measurement according to some example embodiments of the present disclosure is shown. For discussion purposes, reference will be made to Figure 1 The signaling diagram 200 is discussed, for example, by using a first device 110 (e.g., a gNB) and a second device 120 (e.g., a terminal device).

[0040] Reference now Figure 2, the second device 120 may send (202) to the first device 110 a configuration for reporting LP-WUS measurement at the first device 110. The configuration may indicate information of at least one event associated with the LP-WUS measurement. That is, if the first device 110 determines based on the LP-WUS measurement that an event indicated in the configuration occurs, a measurement report may be triggered.

[0041] For example, the information element (IE) "ReportConfigNR" may specify criteria for triggering an NR measurement report event or a conditional handover (CHO), conditional primary and secondary cell (PSCell) addition (CPA), or conditional PSCell change (CPC) event. For events marked as AN such as N equals 1, 2, etc., measurement report events and other events (such as CHO, CPA, or CPC) are based on cell measurement results, which may be derived based on SS / physical broadcast channel (PBCH) blocks or channel state information reference signals (CSI-RS).

[0042] The corresponding event(s) associated with the LP-WUS measurement may also be indicated in the IE and may be labeled as WN, where N is equal to 1, 2, etc. For example, the events indicated in the IE may be listed as follows, where the event(s) associated with the LP-WUS measurement are underlined: Table 2

[0043] In addition, the configuration may also indicate the value of one or more thresholds associated with the at least one event. For example, LP-WUS measurements may be performed for the WUS-RS received at the first device 110, and then the value of one or more thresholds may be related to the signal strength.

[0044] The value of the corresponding threshold associated with at least one event may be included in a radio resource control (RRC) IE. An example of an RRC IE is listed below, where the event(s) associated with LP-WUS measurement and the value of the corresponding threshold are underlined: Table 3

[0045] In addition, regarding the configuration of reporting LP-WUS measurements, there is an IE for indicating the measurement type for the measurement report. That is, the second device 120 can instruct the first device 110 to report (multiple) specific measurements. Examples of IEs are listed below: Table 4

[0046] In this IE, the second device 120 may instruct the first device 110 to report LP-WUS / SS / beacon measurements. It should be understood that in the present disclosure, for the sake of clarity, the LP-WUS / SS / beacon measurements hereinafter may also be referred to as LP-WUS measurements. The terms "LP-WUS", "LP-SS", "LP-beacon", "WUS-RS", and "LP-WUS-RS" in the present disclosure may be considered to have the same or similar meanings.

[0047] Continue to refer Figure 2 , the second device 120 may send ( 204 ) a WUS RS to the first device 110 , for example, before the first device 110 enters an idle or inactive state.

[0048] The first device 110 may then perform ( 206 ) LP-WUS measurement on the WUS RS and determine whether an event associated with the LP-WUS measurement occurs based on the received configuration.

[0049] Figure 3 An example of event W1 criteria according to the present disclosure is shown.

[0050] The first device 110 may obtain the threshold value associated with the reference signal strength from a configuration, for example. Figure 3 , if the first device 110 determines that the signal strength Mw of the received WUS RS satisfies: Mw-Hys>Thresh (1) Then the first device 110 may determine that the signal strength Mw of the received WUS RS satisfies the entry condition of event W1 (hereinafter may also be referred to as the first event), where Mw represents the measured signal strength of the received WUS RS, Hys represents a margin or offset and may be expressed in dB, and Thresh represents a threshold reference signal strength and may be expressed in the same unit as Mw. For example, event W1 may indicate that the service LP-WUS / SS / beacon becomes better than a threshold.

[0051] If the first device 110 determines that the signal strength Mw of the received WUS RS satisfies: Mw+Hys <Thresh (2) The first device 110 can then determine that the signal strength Mw of the received WUS RS satisfies the exit condition of the event W1, where Mw represents the measured signal strength of the received WUS RS, Hys represents the margin or offset and can be expressed in dB, and Thresh represents the threshold reference signal strength and can be expressed in the same unit as Mw.

[0052] Figure 4 An example of an event W2 standard according to the present disclosure is shown.

[0053] refer to Figure 4 , if the first device 110 determines that the signal strength Mw of the received WUS RS satisfies: Mw+Hys <Thresh (3) The first device 110 may determine that the signal strength Mw of the received WUS RS satisfies the entry condition of event W2 (hereinafter may also be referred to as the second event), where Mw represents the measured signal strength of the received WUS RS, Hys represents a margin or offset and may be expressed in dB, and Thresh represents a threshold reference signal strength and may be expressed in the same unit as Mw. Event W2 may, for example, indicate that the service LP-WUS / SS / beacon becomes worse than a threshold.

[0054] If the first device 110 determines that the signal strength Mw of the received WUS RS satisfies: Mw–Hys>Thresh (4) The first device 110 can then determine that the signal strength Mw of the received WUS RS meets the exit condition of the event W2, where Mw represents the measured signal strength of the received WUS RS, Hys represents the margin or offset and can be expressed in dB, and Thresh represents the threshold reference signal strength and can be expressed in the same unit as Mw.

[0055] In addition, based on the configuration, the first device 110 may also be required to report neighbor cell LP-WUS / SS / beacon measurements, which may also be referred to as event Wn hereinafter.

[0056] For example, neighbor cell LP-WUS / SS / beacon measurements may also be configured with a periodic reporting type having NR-RS-Type-lp-wus / ss / beacon, as shown in Table 4 above.

[0057] As a result, after performing LP-WUS measurements on the serving cell or (multiple) neighboring cells, if configured, if the first device 110 determines event W1 or W2 or Wn (if configured), the first device 110 can send (208) a measurement report indicating event W1 or W2, or the results of the neighboring cell LP-WUS / SS / beacon measurements (if configured to report).

[0058] Based on the measurement report, some actions may be performed (210) by the second device. For example, when the first device 110 reports the event W2 to the second device, the second device 120 may configure the first device 110 with an event W1 for the serving cell, which may instruct the first device 110 to determine and / or report the event W1 for the serving cell. Further, the second device 120 may also configure the first device 110 to report an event Wn for (multiple) neighboring cells.

[0059] Additionally or optionally, when the first device 110 reports event W2 to the second device, the second device 120 may consider shutting down the LP-WUS operation of the RRC connection of the first device 110. It is also possible that when event W2 occurs, the shutting down of the LP-WUS operation of the RRC connection of the first device 110 may also be initiated by the first device 110 itself.

[0060] In addition, when the first device 110 reports the event W2 to the second device, the second device 120 may also configure a traditional measurement event.

[0061] As another example, when the first device 110 reports event W1 to the second device, the second device 120 may configure event W2 for the serving cell to the first device 110, which may instruct the first device 110 to determine and / or report event W2 for the serving cell.

[0062] Optionally, when the first device 110 reports the event Wn to the second device 120, the second device 120 may configure other measurement events / reports including traditional measurement reports and other proposed measurement reports. In addition, the second device 120 may also trigger a handover if the serving LP-WUS is below a threshold or chooses to operate in an RRC-connected LP-WUS operation. It is also possible that if the event Wn has been reported, the first device 110 may also choose to operate in an RRC-connected LP-WUS operation.

[0063] In some embodiments, the second device 120 may perform actions based on measurement reports of both LP-WUS measurements and conventional NR measurements (such as SSB measurements and / or CSI-RS measurements). Examples of actions performed at the second device 120 based on corresponding (multiple) measurement results and / or events are listed below, where "w" indicates that the measurement value is worse than a threshold and "B" indicates that the measurement value is better than a threshold. Table 5

[0064] In some embodiments, the WUS-RS transmitted from the second device 120 to the first device 110 may have a quasi co-location (QCL) relationship with a SS / PBCH block (SSB) beam. In this case, the WUS-RS may be quasi co-located with the SSB beam. The QCL relationship between the SSB and the WUS-RS may enable the first device 110 to estimate the SSB signal strength by measuring the WUS-RS (e.g., the WUS-RS signal strength).

[0065] For example, in the case where the WUS-RS is a narrow beam compared to the underlying SSB beam, the beam gain of the WUS-RS can be greater than the SSB beam. An offset between the signal strengths of the SSB beam and the WUS-RS beam can be provided to help the first device 110 estimate the SSB signal strength based on the WUS-RS signal strength.

[0066] In some embodiments, the second device 120 may configure the QCL relationship between the WUS-RS and the SSB in a transmission configuration indication (TCI) allocated by the second device 120 .

[0067] In some embodiments, the LP-WUS / SS / beacon may be quasi-co-located with the SSB to enable the first device 110 to estimate the NR SSB signal strength based on the LP-WUS / SS / beacon measurements.

[0068] In some embodiments, when LP-WUS beamforming is performed, the WUS-RS is of type C quasi-co-located with the SSB or the WUS-RS is of type D quasi-co-located with the SSB. In some other embodiments, a non-zero power (NZP) WUS-RS may be used to estimate signal strength and a zero power (ZP) WUS RS may be used to estimate a signal-to-noise ratio (SNR).

[0069] In some embodiments, the first device 110 may wake up the MR for (relaxed) RRM measurements and obtain a new WUS-RS after beam sweeping / refining, the new WUS-RS being quasi-co-located with the latest SSB beam.

[0070] In some embodiments, the second device 120 may allocate a quasi-co-located WUS-RS using the LP-WUS data channel / resource. The WUS-RS may then enable the LR of the first device 110 to estimate the WUS data channel.

[0071] In some embodiments, the second device 120 may allocate a quasi-co-located WUS-RS using the active TCI state LP-WUS data channel / resource of the first device 110. The WUS-RS may then enable the LR of the first device 110 to estimate the WUS data channel. This will enable the LR to measure the WUS-RS and estimate the NR signal. This may enable the first device 110 to relax the RRC connection mode of the measurement.

[0072] In addition, a coordinated relationship between the measurement of MR SSB and the LR WUS-RS measurement may be established by the first device 110. In this case, a coordinated relationship with the LR-based LP-WUS / SS / beacon measurement and the MR-based SSB measurement may be established.

[0073] For example, the first device 110 may estimate the coordination relationship between the measurement of the MR SSB and the LR WUS-RS measurement (SSB and LP-WUS / SS / beacon are quasi co-located type X).

[0074] As another option, the second device 120 may assign a new threshold to the first device 110 to measure the SSB (eg, SSB index) using MR and to measure the WUS-RS (C quasi-co-located with the SSB) using LR.

[0075] In some embodiments, before entering LP-WUS operation in RRC idle / inactive or RRC connected mode (RRC connected mode for LP-WUS applications), the LR of the first device 110 can establish a cooperative relationship with the MR-based measurement. Figure 5 An example of a cooperative relationship between LR- and MR-based measurements of LP-WUS / SS / Beacon and NR signals according to some example embodiments of the present disclosure is shown.

[0076] In some embodiments, if the first device determines that a perfect cooperative relationship is not established, the LR of the first device 110 may use the most recent cooperative relationship. The first device 110 may choose to wake up the MR with a certain coefficient margin based on the measurement of the LR.

[0077] In some embodiments, the first device 110 may choose to periodically wake up the MR for RRM measurements in case of an imperfect coordinated relationship.

[0078] In some embodiments, the first device 110 may verify / update the cooperative relationship in each instance of MR wakeup.

[0079] In some embodiments, the first device 110 can select a timer-based strategy to verify / update the collaborative relationship.

[0080] In some other embodiments, the first device 110 may choose to wake up the MR for RRM-based measurement exemption / relaxation based on the mobility of the first device 110. For example, if the first device 110 is in a high mobility state, the first device 110 may choose to have a shorter RRM measurement relaxation or no RRM measurement relaxation. Similarly, the first device 110 may select an appropriate RRM measurement relaxation. Figure 6 An example of a coordinated relationship between LP-WUS measurements based on MR's RRM measurements and UE mobility state according to some example embodiments of the present disclosure is shown.

[0081] On the other hand, based on the solution of the present disclosure, the first device may establish RRM measurement relaxation based on WUS-RS measurement.

[0082] For example, if the latest WUS-RS measurement is lower than the WUS-RS measurement carried on the previous instance and the latest WUS-RS measurement is lower than the threshold assigned by the second device 120, the first device 110 may choose to wake up the MR for RRM-based measurement.

[0083] As another example, if the latest WUS-RS measurement is equal to / higher than the WUS-RS measurement carried at the previous instance and the latest WUS-RS measurement is higher than a threshold assigned by the second device 120, the first device 110 may choose to skip MR-based RRM measurement.

[0084] It is also possible that if the latest WUS-RS measurement is lower than the WUS-RS measurement carried at the previous instance and the latest WUS-RS measurement is lower than the threshold assigned by the second device 120, the first device 110 can measure the WUS-RS, which is quasi-co-located with the adjacent SSB beam. If the measurement result is different from the previous result, the first device 110 can choose to wake up the MR for RRM-based measurement. Conversely, if the measurement result has not changed relative to the previous result, the first device 110 can choose to skip the MR-based RRM measurement.

[0085] In yet another aspect, based on the solution of the present disclosure, CHO can be enhanced by taking into account LP-WUS measurements.

[0086] In some embodiments, in addition to the traditional CHO condition (which may be referred to as the NR CHO condition), the second device 120 may also configure a CHO condition associated with LP-WUS measurement, which may be referred to as the LP-WUS CHO condition.

[0087] In some embodiments, when the LP-WUS CHO condition is satisfied but the NR CHO condition is not satisfied, the first device 110 may stop the LP-WUS operation in the RRC-connected mode and / or evaluate whether the handover (HO) in the condition of the neighboring cell is satisfied. If so, the first device 110 may then perform HO to the selective neighboring cell.

[0088] In some embodiments, when the LP-WUS CHO condition is not met but the NR CHO condition is met, the first device 110 may HO to the best target cell with the NR CHO condition, and based on the associated LP-WUS strength, may choose to operate in RRC connected mode LP-WUS operation. Alternatively, if any candidate cell meets the serving cell W1 criterion, the first device 110 may HO to the best target cell.

[0089] In some embodiments, when the NR CHO condition is satisfied and the LP-WUS CHO condition is satisfied, the first device 110 may select HO to the best cell based on the enhanced CHO condition (ie, considering the LP-WUS strength while evaluating the HO CHO condition).

[0090] In this way, the UE's LR can perform measurements of LP-WUS / SS / beacon signals to offload the MR for RRM measurements without compromising UE reachability and mobility while still achieving WUS mode power savings.
