[0003] 5G communication systems are implemented in higher frequency (millimeter wave, mmWave) bands, such as the 60 GHz band, to achieve higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antenna technology are discussed in 5G communication systems.

[0004] In addition, in the 5G communication system, development of system network improvements is underway based on advanced small cells, cloud radio access networks (RAN), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, collaborative communications, coordinated multi-point (CoMP), receiving-end interference cancellation, etc.

[0051] Figure 1 An example wireless network 100 is shown in accordance with various embodiments of the present disclosure. Figure 1 The embodiment of the wireless network 100 shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 can be used without departing from the scope of the present disclosure.

[0052] Wireless network 100 includes gNodeB (gNB) 101, gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one Internet Protocol (IP) network 130, such as the Internet, a private IP network, or other data network.

[0053] Depending on the network type, other well-known terms such as "base station" or "access point" can be used instead of "gNodeB" or "gNB". For convenience, the terms "gNodeB" and "gNB" are used in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Also, depending on the network type, other well-known terms such as "mobile station", "subscriber station", "remote terminal", "wireless terminal" or "user device" can be used instead of "user equipment" or "UE". For convenience, the terms "user equipment" and "UE" are used in this patent document to refer to a remote wireless device that wirelessly accesses a gNB, whether the UE is a mobile device (such as a mobile phone or smartphone) or a commonly thought of fixed device (such as a desktop computer or vending machine).

[0054] gNB 102 provides wireless broadband access to network 130 for a first plurality of user equipment (UE) within coverage area 120 of gNB 102. The first plurality of UEs include: UE 111, which may be located in a small business (SB); UE 112, which may be located in an enterprise (E); UE 113, which may be located in a WiFi hotspot (HS); UE 114, which may be located in a first residence (R); UE 115, which may be located in a second residence (R); UE 116, which may be a mobile device (M), such as a cellular phone, a wireless laptop, a wireless PDA, etc. gNB 103 provides wireless broadband access to network 130 for a second plurality of UEs within coverage area 125 of gNB 103. The second plurality of UEs include UE 115 and UE 116. In some embodiments, one or more of gNBs 101-103 may be capable of communicating with each other and with UEs 111-116 using 5G, long term evolution (LTE), LTE-A, WiMAX, or other advanced wireless communication technologies.

[0055] The dashed lines illustrate the approximate extents of coverage areas 120 and 125, which are shown as approximately circular for purposes of illustration and explanation only. It should be clearly understood that coverage areas associated with gNBs, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.

[0056] As described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook design and structure for a system with a 2D antenna array.

[0057] although Figure 1 One example of a wireless network 100 is shown, but Figure 1 Various changes may be made. For example, wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Also, gNB 101 can communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. In addition, gNBs 101, 102, and / or 103 can provide access to other or additional external networks, such as an external telephone network or other type of data network.

[0058] Figure 2a and Figure 2b Example wireless transmit and receive paths according to the present disclosure are shown. In the following description, transmit path 200 can be described as being implemented in a gNB (such as gNB 102) and receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that receive path 250 can be implemented in a gNB and transmit path 200 can be implemented in a UE. In some embodiments, receive path 250 is configured to support codebook design and structure for a system with a 2D antenna array as described in embodiments of the present disclosure.

[0059] The transmit path 200 includes a channel coding and modulation block 205, a serial to parallel (S to P) block 210, an N-point inverse fast Fourier transform (IFFT) block 215, a parallel to serial (P to S) block 220, an add cyclic prefix block 225, and an upconverter (UC) 230. The receive path 250 includes a downconverter (DC) 255, a remove cyclic prefix block 260, a serial to parallel (S to P) block 265, an N-point fast Fourier transform (FFT) block 270, a parallel to serial (P to S) block 275, and a channel decoding and demodulation block 280.

[0060] In the transmit path 200, the channel coding and modulation block 205 receives a set of information bits, applies coding (such as low-density parity check (LDPC) coding), and modulates the input bits (such as using quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM)) to generate a sequence of frequency-domain modulation symbols. The serial-to-parallel (S-to-P) block 210 converts (such as demultiplexes) the serial modulation symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points used in the gNB 102 and the UE 116. The N-point IFFT block 215 performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. The parallel-to-serial block 220 converts (such as multiplexes) the parallel time-domain output symbols from the N-point IFFT block 215 to generate a serial time-domain signal. The add cyclic prefix block 225 inserts a cyclic prefix into the time-domain signal. The up-converter 230 modulates (such as up-converts) the output of the add cyclic prefix block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at baseband before conversion to RF frequency.

[0061] The RF signal transmitted from gNB 102 arrives at UE 116 after passing through a wireless channel, and an operation opposite to that at gNB 102 is performed at UE 116. Downconverter 255 downconverts the received signal to a baseband frequency, and remove cyclic prefix block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel block 265 converts the time-domain baseband signal into a parallel time-domain signal. N-point FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. Parallel-to-serial block 275 converts the parallel frequency-domain signals into a sequence of modulated data symbols. Channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0062] Each of gNBs 101-103 may implement a transmit path 200 similar to that for transmitting in the downlink to UEs 111-116 and may implement a receive path 250 similar to that for receiving in the uplink from UEs 111-116. Similarly, each of UEs 111-116 may implement a transmit path 200 for transmitting in the uplink to gNBs 101-103 and may implement a receive path 250 for receiving in the downlink from gNBs 101-103.

[0063] Figure 2a and Figure 2b Each of the components in can be implemented using hardware only, or a combination of hardware and software / firmware. As a specific example, Figure 2a and Figure 2bAt least some of the components in can be implemented with software, while other components can be implemented by configurable hardware or a mixture of software and configurable hardware. For example, FFT block 270 and IFFT block 215 can be implemented as a configurable software algorithm, in which the value of the number of points N can be modified according to the implementation.

[0064] In addition, although described as using FFT and IFFT, this is illustrative only and should not be construed as limiting the scope of the present disclosure. Other types of transforms can be used, such as discrete Fourier transform (DFT) and inverse discrete Fourier transform (IDFT) functions. It should be understood that for DFT and IDFT functions, the value of variable N can be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N can be any integer as a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0065] although Figure 2a and Figure 2b An example of a wireless transmit and receive path is shown, but the Figure 2a and Figure 2b Make various changes. For example, Figure 2a and Figure 2b The various components in can be combined, further subdivided or omitted, and additional components can be added according to specific needs. Figure 2a and Figure 2b It is intended to illustrate examples of the types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communications in a wireless network.

[0066] Figure 3a An example UE 116 according to the present disclosure is shown. Figure 3a The embodiment of UE 116 shown in FIG. 1 is for illustration only, and Figure 1 UEs 111-115 can have the same or similar configurations. However, UEs have a variety of configurations, and Figure 3a The scope of the present disclosure is not limited to any particular implementation of the UE.

[0067] UE 116 includes antenna 305, radio frequency (RF) transceiver 310, transmit (TX) processing circuit 315, microphone 320, and receive (RX) processing circuit 325. UE 116 also includes speaker 330, processor / controller 340, input / output (I / O) interface 345, input device(s) 350, display 355, and memory 360. Memory 360 includes operating system (OS) 361 and one or more applications 362.

[0068] The RF transceiver 310 receives incoming RF signals from the antenna 305 transmitted by the gNB of the wireless network 100. The RF transceiver 310 downconverts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to the RX processing circuit 325, where the RX processing circuit 325 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. The RX processing circuit 325 sends the processed baseband signal to the speaker 330 (such as for voice data) or to the processor / controller 340 (such as for web browsing data) for further processing.

[0069] The TX processing circuit 315 receives analog or digital voice data from the microphone 320, or receives other outgoing baseband data (such as network data, email, or interactive video game data) from the processor / controller 340. The TX processing circuit 315 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 310 receives the outgoing processed baseband or IF signal from the TX processing circuit 315 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 305.

[0070] The processor / controller 340 can include one or more processors or other processing devices and execute an OS 361 stored in the memory 360 to control the overall operation of the UE 116. For example, the processor / controller 340 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceiver 310, the RX processing circuit 325, and the TX processing circuit 315 according to well-known principles. In some embodiments, the processor / controller 340 includes at least one microprocessor or microcontroller.

[0071] The processor / controller 340 is also capable of executing other processes and programs resident in the memory 360, such as operations for channel quality measurement and reporting for a system with a 2D antenna array as described in the embodiments of the present disclosure. The processor / controller 340 is capable of moving data into or out of the memory 360 as needed for the executed process. In some embodiments, the processor / controller 340 is configured to execute applications 362 based on the OS 361 or in response to signals received from the gNB or operator. The processor / controller 340 is also coupled to the I / O interface 345, where the I / O interface 345 provides the UE 116 with the ability to connect to other devices such as laptops and handheld computers. The I / O interface 345 is the communication path between these accessories and the processor / controller 340.

[0072] Processor / controller 340 is also coupled to input device(s) 350 and display 355. An operator of UE 116 can input data into UE 116 using input device(s) 350. Display 355 can be a liquid crystal display or other display capable of presenting text and / or at least limited graphics (such as from a website). Memory 360 is coupled to processor / controller 340. A portion of memory 360 can include random access memory (RAM), while another portion of memory 360 can include flash memory or other read-only memory (ROM).

[0073] although Figure 3a An example of UE 116 is shown, but it is possible to Figure 3a Make various changes. For example, Figure 3a The various components in can be combined, further subdivided, or omitted, and additional components can be added according to specific needs. As a specific example, processor / controller 340 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Moreover, although Figure 3a The UE 116 is shown configured as a mobile phone or smart phone, but the UE can be configured to operate as other types of mobile or stationary devices.

[0074] Figure 3b An example gNB 102 according to the present disclosure is shown. Figure 3b The embodiment of the gNB 102 shown in FIG. is for illustration only, and Figure 1 Other gNBs can have the same or similar configurations. However, gNBs have a variety of configurations, and Figure 3b The scope of the present disclosure is not limited to any particular implementation of the gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structure as gNB 102.

[0075] like Figure 3b As shown in FIG. 1 , gNB 102 includes multiple antennas 370a-370n, multiple RF transceivers 372a-372n, transmit (TX) processing circuitry 374, and receive (RX) processing circuitry 376. In some embodiments, one or more of the multiple antennas 370a-370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0076] The RF transceivers 372a-372n receive incoming RF signals from the antennas 370a-370n, such as signals transmitted by a UE or other gNB. The RF transceivers 372a-372n downconvert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to the RX processing circuitry 376, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The RX processing circuitry 376 sends the processed baseband signals to the controller / processor 378 for further processing.

[0077] The TX processing circuit 374 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from the controller / processor 378. The TX processing circuit 374 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceivers 372a-372n receive the outgoing processed baseband or IF signals from the TX processing circuit 374 and up-convert the baseband or IF signals to RF signals that are transmitted via the antennas 370a-370n.

[0078] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceivers 372a-372n, the RX processing circuitry 376, and the TX processing circuitry 374 in accordance with well-known principles. The controller / processor 378 can also support additional functionality, such as more advanced wireless communication functionality. For example, the controller / processor 378 can perform a Blind Interference Sensing (BIS) process, such as performed through a Blind Interference Sensing (BIS) algorithm, and decode a received signal with an interference signal subtracted. The controller / processor 378 can support any of a variety of other functions in the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0079] The controller / processor 378 can also execute programs and other processes resident in the memory 380, such as a basic OS. The controller / processor 378 can also support channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. In some embodiments, the controller / processor 378 supports communications between entities such as web RTC. The controller / processor 378 can move data into or out of the memory 380 as needed by the executing process.

[0080] The controller / processor 378 is also coupled to a backhaul or network interface 382. The backhaul or network interface 382 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or via a network. The backhaul or network interface 382 can support communication via any suitable (multiple) wired or wireless connections. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G or new radio access technology or NR, LTE or LTE-A), the backhaul or network interface 382 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow the gNB 102 to communicate with a larger network (such as the Internet) via a wired or wireless local area network or via a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication via a wired or wireless connection, such as an Ethernet or RF transceiver.

[0081] The memory 380 is coupled to the controller / processor 378. A portion of the memory 380 can include RAM, while another portion of the memory 380 can include flash memory or other ROM. In some embodiments, a plurality of instructions such as a BIS algorithm are stored in the memory. The plurality of instructions are configured to cause the controller / processor 378 to perform the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.

[0082] As described in more detail below, the transmit and receive paths of the gNB 102 (implemented using the RF transceivers 372a-372n, the TX processing circuitry 374, and / or the RX processing circuitry 376) support aggregated communications with FDD cells and TDD cells.

[0083] although Figure 3b An example of a gNB 102 is shown, but the Figure 3b For example, gNB 102 can include any number of Figure 3a . As a specific example, an access point can include a number of backhaul or network interfaces 382, ​​and the controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, while shown as including a single instance of TX processing circuitry 374 and a single instance of RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0084] The time domain unit (also called time unit) in the present application can be: an OFDM symbol, an OFDM symbol group (consisting of multiple OFDM symbols), a time slot, a time slot group (consisting of multiple time slots), a subframe, a subframe group (consisting of multiple subframes), a system frame, a system frame group (consisting of multiple system frames); it can also be an absolute time unit, such as 1 millisecond, 1 second, etc.; the time unit can also be a combination of multiple granularities, such as N1 time slots plus N2 OFDM symbols.

[0085] The frequency domain unit (also called frequency unit) in the present application can be: a subcarrier, a subcarrier group (consisting of multiple subcarriers), a resource block (resource block, RB), which can also be called a physical resource block (physicalresource block, PRB), a resource block group (consisting of multiple RBs), a bandwidth part (bandwidth part, BWP), a band part group (consisting of multiple BWPs), a band / carrier, a band group / carrier group; it can also be an absolute frequency domain unit, such as 1 Hz, 1 kHz, etc.; the frequency domain unit can also be a combination of multiple granularities, such as M1 PRBs plus M2 subcarriers.

[0086] Exemplary embodiments of the present disclosure are further described below in conjunction with the accompanying drawings.

[0087] The text and drawings are provided as examples only to help readers understand the present disclosure. They are not intended and should not be interpreted as limiting the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, it is obvious to those skilled in the art based on what is disclosed herein that the embodiments and examples shown may be changed without departing from the scope of the present disclosure.

[0088] The transmission links of the wireless communication system mainly include: the downlink communication link from the 5G New Radio (NR) gNB to the user equipment (UE), the uplink communication link from the UE to the network, and the sidelink communication link from the UE to the UE.

[0089] In a wireless communication system, for example, in a current wireless communication system, in order to reduce the energy consumption on the terminal side, a discontinuous reception (DRX) mechanism is introduced, so that the UE can be in a sleep state for most of the time, and only needs to be awakened periodically to monitor the paging occasion (PO). In a DRX cycle, the UE only wakes up during the DRX activation duration (DRX ON duration) to monitor the PO. After monitoring the PDCCH scrambled by the P-RNTI, the UE continues to read the terminal flag of the paged terminal in the paging message. If the read terminal flag is the same as its own flag, the UE further reads the paging message, otherwise, the paging message is discarded. In the above process, in order to further reduce the energy consumption of the UE, a paging early indication (PEI) signal is introduced to indicate whether the UE needs to monitor the corresponding PO. If the system information provides a PEI configuration, the UE monitors a PEI occasion (PEI occasion) once in each DRX cycle. If the UE detects a PEI indication and the PEI indicates that the UE monitors the associated PO, the UE should wake up at the next PO to monitor the PO; otherwise, the UE does not need to wake up to monitor the PO.

[0090] In the RRC connected state, each DRX cycle includes an active period (Active Time) and a non-active period (Non-active Time). During the active period, the UE needs to monitor the PDCCH, and during the non-active period, the UE does not need to monitor the PDCCH. The UE starts the drx-onDurationTimer (DRX duration timer) at the beginning of each DRX cycle to start monitoring the PDCCH. During the transmission process, if the UE monitors the downlink control information (Downlink Control Information, DCI) scheduling new data transmission, the UE starts the drx-inactivityTimer (DRX non-active timer). During the DRX active period, the base station can instruct the UE to enter the DRX non-active period in advance through signaling, or, when all DRX timers of the UE stop running, the UE can enter the DRX non-active period.

[0091] In some use cases with stricter requirements on UE low energy consumption (such as IoT devices and / or wearable devices), an enhanced wake-up signal monitoring method is needed to further extend the battery life of the UE.

[0092] Optionally, the enhanced wake-up signal can also be used for RRM measurement

[0093] Specifically, in the present invention, a method and device for configuring and monitoring a low power wake-up signal will be introduced. In this embodiment, LPWUS (Low Power Wake Up Signal, LPWUS) is used for exemplary introduction, and the introduced method can also be used for the configuration and transmission of other signals.

[0094] The receiver of the UE includes two modules, one is the main wireless communication module (Main Radio, MR), which is used to receive the regular signal / channel sent by the base station, and the other is the low power wake-up signal receiving module (Lower Power Wake Up Receiver, LPWUR), which is used to receive the first signal sent by the base station. The use of a dedicated module to receive the first signal is because LPWUS is based on the existing NR system based on orthogonal frequency division multiplexing (OFDM) waveform and further based on amplitude shift keying (ASK) modulation and / or frequency shift keying (FSK) modulation waveform. LPWUR can monitor the first signal at extremely low power. Once the UE monitors LPWUS, LPWUR can trigger MR to switch from the sleep period to the activation period, so that specific operations can be performed. Optionally, on-off keying (OOK) modulation is a special case of amplitude shift keying (ASK) modulation. The first signal may be used for synchronization and / or radio resource management RRM measurement, and may include at least one of the following: LPWUS and / or a low power synchronization signal LP-SS (Lower Power synchronization signal) for synchronization and / or SSB and / or PSS and / or SSS and / or PBCH DMRS and / or TRS. The second signal may be a signal for waking up the UE, for example, may be LPWUS. The first signal and the second signal may both be wake-up signals.

[0095] In some implementations, a method for determining a time domain position of a second signal monitoring opportunity is provided. Figure 4 As shown, in step S401, configuration information related to the time domain position of a signal is received. Optionally, in step S402, the time domain position of a first signal is determined according to the configuration information, wherein the first signal is used for synchronization and / or radio resource management RRM measurement. Optionally, in step S403, based on the time domain position of the first signal, the time domain position of a monitoring opportunity of a second signal is determined, wherein the second signal is used for wake-up.

[0096] The UE may use the second signal to reduce power consumption. The UE obtains configuration information of the first signal and / or the second signal by receiving a radio resource control RRC message and / or a high-level parameter. If the configuration information of the first signal and / or the second signal is provided by an RRC message and / or a high-level parameter, a UE supporting the first signal and / or the second signal may monitor the first signal and / or the second signal according to the configuration parameters configured in the RRC message and / or the high-level parameter. Optionally, in the RRC INACTIVE and / or IDLE state, the first signal and / or the second signal may be configured in the SIB and / or MIB and / or small data transmission (SDT). Optionally, in the RRC IDLE state, the first signal and / or the second signal may be configured in a high-level parameter. Among them, the configuration information of the first signal and / or the second signal or the second signal resource or the second signal resource set includes a combination of one or more of the following:

[0097] o The maximum duration of the second signal or the second signal listening opportunity; the duration of the second signal or the second signal listening opportunity may be less than the configured maximum duration of the second signal or the second signal listening opportunity. Optionally, the granularity of the configured maximum duration is the same as the granularity of the associated PO, which may be an OFDM symbol or a time slot or a subframe; Optionally, the method for determining the maximum duration may include a combination of one or more of the following:

[0098] n is represented by the ratio of the duration of "S*X" consecutive PDCCH monitoring opportunities

[0099] (ratio), where "S" is the number of SSBs actually transmitted according to ssb-PositionsInBurst in SIB1, and X is the number of PDCCH monitoring occasions corresponding to SSBs in a paging occasion.

[0100] The value of n can be at least one of the following: 1 / 4, 1 / 8, 1 / 16, 1 / 32, 1 / 64, that is, one of 2 raised to the power of N; wherein N is a real number. This configuration method can ensure that the configured maximum duration is a plurality of consecutive time slots;

[0101] Optionally, the UE determines the maximum duration of the second signal or the second signal monitoring opportunity according to the configured maximum duration, which may be the maximum value of the configured maximum duration and one time unit. Optionally, the time unit may be a time slot or a subframe.

[0102] o The minimum time unit interval or offset from the first reference point where the second signal or the end position of the second signal monitoring opportunity is located to the second reference point, such as Figure 5As shown, the minimum time unit interval should be large enough to ensure that the MR of the UE can be woken up. Optionally, the value of the minimum time unit interval can be configured in ms, for example, it can include at least one of the following: 400ms, 800ms, 1.6s, 3.2s, 4.8s. In another embodiment, optionally, the value of the minimum time unit interval can be the number of radio frames or system frame numbers (SFNs). Optionally, the minimum time unit interval can be configured as a short time interval, and its value can include at least one of the following: 400ms or 40 radio frames, 800ms or 80 radio frames, 1.6s or 160 radio frames, 3.2s or 320 radio frames, 4.8s or 480 radio frames. Optionally, when there is no UE capability reporting, the minimum time unit interval is fixed to C. C can be one of the values ​​of the minimum time unit interval, optionally, C = 400ms or C is 40 radio frames. The UE reports a UE capability whose value may include at least one of the following: 400ms or 40 radio frames, 4.8s or 480 radio frames. For extended DRX, the minimum time unit interval may be configured as a long time interval, whose value may be 10.24s*q or q SFNs. Wherein, q may be a parameter value (pre) configured or predefined by the base station device and / or reported by the UE based on its own processing capability. Wherein, q is a natural number, q is greater than or equal to 1. Optionally, q=1 and / or q=2.

[0103] oThe first reference point may be the end position of the radio frame where the second signal or the end position of the second signal listening opportunity is located, or the end position of the subframe where the second signal or the end position of the second signal listening opportunity is located, or the end position of the time slot where the second signal or the end position of the second signal listening opportunity is located, or the end position of the SFN where the second signal or the end position of the OFDM symbol where the second signal or the end position of the second signal listening opportunity is located, such as Figure 5 The minimum time unit interval or offset 2 is shown in the figure; the end position of the second signal or the second signal monitoring opportunity may include a combination of one or more of the following:

[0104] The end position of the second signal or the second signal listening opportunity may be an end position of a maximum duration of the second signal or the second signal listening opportunity.

[0105] nIf the end position of the second signal or the second signal listening opportunity is different from the end position of the maximum duration, and / or if the granularity of the minimum time unit interval or offset is different from the granularity of the maximum duration, for example, if the granularity of the minimum time unit interval or offset is a radio frame or SFN and the granularity of the maximum duration of the second signal or the second signal listening opportunity is an OFDM symbol or a time slot or a subframe, indicating that the interval or offset from the end position of the maximum duration of the second signal or the second signal listening opportunity to the first reference point is not 0, and the interval or offset may be configured by an RRC message and / or a high-level parameter or SIB, such as Figure 5 As shown in the offset 2, the first reference point can be determined by the maximum duration end position of the second signal or the second signal listening opportunity, and the interval or offset from the maximum duration end position of the second signal or the second signal listening opportunity to the first reference point. The maximum duration end position of the second signal or the second signal listening opportunity can be determined by the second reference point, and the configured interval or offset from the maximum duration end position of the second signal or the second signal listening opportunity to the first reference point, and the configured minimum time unit interval or offset, as shown in the offset 2, Figure 5 As shown in offset 2 and minimum time unit interval or offset 1.

[0106] nIf the end position of the second signal or the second signal listening opportunity is the same as the end position of the maximum duration, and / or if the granularity of the minimum time unit interval or offset is the same as the granularity of the maximum duration, for example, if the granularity of the minimum time unit interval or offset is a radio frame or SFN and the granularity of the maximum duration of the second signal or the second signal listening opportunity is a radio frame or SFN, the first reference point can be the end position of the maximum duration of the second signal or the second signal listening opportunity, and the end position of the maximum duration of the second signal or the second signal listening opportunity can be determined by the second reference point and the minimum time unit interval or offset.

[0107] o The method for determining the second reference point may include a combination of one or more of the following:

[0108] n may be the starting position of the first paging frame in the paging frame associated with the second signal or the second signal monitoring opportunity, or the starting position of the SFN where the paging frame associated with the second signal or the second signal monitoring opportunity is located, such as Figure 5 As shown in the minimum time unit interval or offset 1, this determination method is applicable to the case where the granularity of the minimum time unit interval or offset is SFN or wireless frame.

[0109] n may be the starting position of the time slot where the starting position of the first associated PO in the first paging frame associated with the second signal or the second signal monitoring opportunity is located, or the starting position of the subframe where it is located, or the starting position of the OFDM symbol where it is located, such as Figure 5 As shown in the minimum time unit interval or offset 2, this determination method can minimize the additional resource waste caused by the difference between the minimum time required for the actual MR to change from the ultra-low sleep state to the wake-up state and the configured minimum time interval;

[0110] nThe starting position of the first associated PO can be determined by the ID of the paging search space. When the ID of the paging search space is equal to 0, if a paging frame contains a PO, the starting position of the first associated PO is the starting position of the time unit where the first PDCCH monitoring opportunity for paging is located. When the ID of the paging search space is equal to 0, if a paging frame contains two POs, the starting position of the first associated PO is the starting position of the paging frame where the PO is located or the starting position of the second half of the paging frame where the PO is located, that is, the starting position of the subframe with a subframe index of 5 in the paging frame. When the ID of the paging search space is not equal to 0, the starting position of the first associated PO is the starting position of the time unit where the current PO index plus 1 PO is located.

[0111] o The granularity of the minimum time interval or offset may be a time slot or a subframe or a radio frame and / or a SFN; optionally, if the granularity of the minimum time interval or offset is a SFN or a radio frame, the interval or offset from the maximum duration end position of the second signal or the second signal listening opportunity to the first reference point is not 0;

[0112] Optionally, the configuration information of the first signal or the first signal resource or the first signal resource set includes a combination of one or more of the following:

[0113] n A maximum number of consecutive DRX cycles in which the UE can use the first signal for synchronization and skip serving cell measurement; during the DRX cycle, the UE does not perform RRM measurement and / or the UE does not monitor the SSB and the first signal.

[0114] n is a set of first signals to be measured within the maximum duration. If this field is not configured, the UE measures all first signals configured within the maximum duration;

[0115] oThe period of the first signal;

[0116] The determination method of the minimum time unit interval or offset of the second signal may include a combination of one or more of the following:

[0117] o Predefined or (pre)configured via higher layer parameters and / or RRC parameters;

[0118] o If the long time interval is not configured or not broadcasted, the minimum time unit interval may be determined by a predefined or (pre)configured short time interval. Optionally, the minimum time unit interval is equal to the short time interval. Optionally, the configured minimum time unit interval should be greater than and / or equal to or not less than the minimum time unit interval reported by the UE.

[0119] o If the long time interval is configured or broadcasted, or both the short time interval and the long time interval are configured, and / or when the UE reports the UE capability of the minimum time unit interval from the end of the maximum duration of one or more first signals to the first associated PO, the determination method of the minimum time unit interval may include a combination of one or more of the following:

[0120] nIf the configured minimum time unit interval is equal to the minimum time unit interval reported by the UE, the minimum time unit interval is equal to the configured minimum time unit interval;

[0121] If the UE does not report the minimum time unit interval or the reported minimum time unit interval is one or more of the short unit intervals, the minimum time unit interval may be determined according to the (pre)configured or predefined short time interval. Optionally, the configured minimum time unit interval should be greater than and / or equal to or not less than the minimum time unit interval reported by the UE. This method ensures that the UE can wake up the MR within the configured short time interval to listen to PO and / or receive paging and / or establish an RRC connection.

[0122] nIf the configured minimum time unit interval is smaller than the minimum time unit interval reported by the UE, the UE uses the configured short time interval to monitor the second signal, that is, the minimum time unit interval is equal to the configured short time interval; optionally, if the configured minimum time unit interval is smaller than the maximum value of multiple minimum time unit intervals reported by multiple UEs in the UE group, the UE uses the configured short time interval to monitor the second signal. Optionally, the configured minimum time unit interval and / or the minimum time unit interval reported by the UE is a long time interval. This method is because the UE capability reported by the UE cannot meet the network configuration, so the UE uses the configured short time interval to determine the minimum time unit interval to wake up the MR more quickly;

[0123] If the configured minimum time unit interval is smaller than the minimum time unit interval reported by the UE, or if the configured minimum time unit interval is smaller than the maximum value of multiple minimum time unit intervals reported by multiple UEs in the UE group,

[0124] The UE uses the minimum time unit interval reported by the UE. This approach can ensure that the UE with the worst UE capability can be awakened in sufficient time to monitor PO and / or receive paging and / or establish an RRC connection;

[0125] If the configured minimum time unit interval is greater than the minimum time unit interval reported by the UE, the UE uses the configured longer time interval to monitor the second signal, that is, the minimum time unit interval is equal to the configured longer time interval. This method further meets the expectations of the network on the basis of meeting the UE capabilities.

[0126] In another embodiment, since the first signal cycle is long, if the second signal monitoring opportunity is far away from the first signal, it is not guaranteed that the second signal can be correctly received at the LR of the UE. In order to reduce the false alarm rate and false alarm rate of the second signal monitoring, the method for determining the time domain position of the second signal monitoring opportunity may include a combination of one or more of the following:

[0127] o The time domain OFDM symbol or time slot start position of the second signal monitoring opportunity for wake-up is determined by the end or start position of the OFDM symbol or time slot of the first signal or the first signal burst and a preconfigured or predefined first offset, and the granularity of the offset can be an OFDM symbol or time slot, such as Figure 6 This determination method can ensure that the time-frequency offset of the received second signal is within a certain range, that is, the second signal can be correctly received.

[0128] o The end position of the time domain OFDM symbol or time slot of the second signal monitoring opportunity for wake-up is determined by the end or start position of the OFDM symbol or time slot of the first signal or the first signal burst and a preconfigured or predefined second offset, and the granularity of the offset can be an OFDM symbol or time slot, such as Figure 6 This determination method can ensure that the last second signal or the repetition of the second signal received by the UE is still within the second signal time-frequency offset acceptable to the UE.

[0129] During the second signal monitoring opportunity for wake-up, one or more second signals may be configured, and the association relationship between the second signal and the PO may include a combination of one or more of the following:

[0130] oEach second signal can be associated with at most K consecutive POs, and the starting position of the first PO associated with the second signal can be determined by the end position of the ith second signal and the configured minimum time unit interval or offset. Optionally, the starting position of the first PO closest to the end position of the ith second signal plus the configured minimum time unit interval or offset is the starting position of the first PO associated with the ith second signal, such as Figure 6 As shown in the figure, i is a real number greater than or equal to 1.

[0131] o The second signal in the second signal listening opportunity for wakeup can be associated with all POs starting from the end position of the second signal listening opportunity, with the starting position of the first PO after the minimum time unit interval being the starting point, and ending at the starting position of the first PO associated with the next first signal listening opportunity being the end point, such as Figure 6 As shown. A second signal can be configured to wake up the UE to monitor all the POs, and / or multiple first signals can be configured in the second signal monitoring opportunity, and each second signal can be associated with L consecutive POs, for example, the first second signal monitored in the second signal monitoring opportunity is associated with the first PO starting to the Lth PO, the second second signal is associated with the L+1th PO starting to the 2Lth PO, and so on;

[0132] o K and L can be parameter values ​​reported by the user equipment UE according to its own processing capability and

[0133] / or a parameter value configured by a base station and / or a preconfigured parameter value and / or a predefined parameter value received by the UE. Wherein, K and L are real numbers greater than 0.

[0134] Optionally, when the received signal strength RSRP of the first signal is greater than or equal to a predefined or preconfigured first threshold value and / or the received signal quality RSRQ is greater than or equal to a predefined or preconfigured second threshold value, or when the cell selection reception (RX) level value (S R R Q ) calculated by the UE based on the RSRP measured by the first signal is satisfied rxlev ) is greater than or equal to a predefined or (pre) configured third threshold value and / or the cell selection quality value calculated by the UE based on the RSRQ measured by the first signal is greater than or equal to a predefined or (pre) configured fourth threshold value, the second signal monitoring opportunity may be used to monitor the second signal;

[0135] In another embodiment, since the startup time of the UE switching from the ultra-low deep sleep state to the awake state is relatively long, the network may page other UEs in the same UE group during the startup time of one or more UEs awakened by the current second signal. In order to reduce the delay of the UE receiving the paging message, the second signal monitoring opportunity can be periodically configured, such as Figure 7 As shown, if the UE receives a second signal and the second signal wakes up the corresponding UE, the UE no longer monitors the subsequent second signal listening opportunity, and the UE wakes up to monitor the associated PO that meets the minimum time unit interval, and the associated PO starts from the end position of the second signal listening opportunity, and the starting position of the first PO after meeting the minimum time unit interval is the starting point, and the starting position of the first PO associated with the next second signal listening opportunity is the end point for all POs. If the UE does not receive a paging message on the PO or the paging message received by the UE does not instruct the UE to establish an RRC connection, the UE re-enters the ultra-low sleep state and periodically monitors the second signal listening opportunity for wake-up.

[0136] In some embodiments, examples of UE behavior when a collision occurs are described.

[0137] The resource mapping method and / or transmission method of the first signal and / or the second signal may include a combination of one or more of the following:

[0138] o The time unit satisfying the first condition is counted when the first signal and / or the second signal are mapped but is not used for the transmission of the first signal and / or the second signal; optionally, the first signal and / or the second signal satisfying the first condition is a first signal and / or a second signal that are repeatedly transmitted, and this is because in the first condition, other signals that overlap or collide with the first signal and / or the second signal are more important;

[0139] o The time unit satisfying the first condition is not counted when the first signal and / or the second signal are mapped and is not used for the transmission of the first signal and / or the second signal; optionally, the first signal and / or the second signal satisfying the first condition is a first signal and / or a second signal that is repeatedly transmitted, and this is because in the first condition, other signals that overlap or collide with the first signal and / or the second signal are more important;

[0140] o When the first condition is met, the time unit of the first signal and / or the second signal is discarded, and optionally, the time unit where the first signal and / or the second signal is located is discarded; optionally, the first signal and / or the second signal that meets the first condition is a first signal and / or a second signal that is repeatedly sent, and this method is because in the first condition, other signals that overlap or collide with the first signal and / or the second signal are more important;

[0141] o When the first condition is met, the first signal and / or the second signal time unit is received, that is, it is counted when the first signal and / or the second signal is mapped and used for the transmission of the first signal and / or the second signal; optionally, the first signal and / or the second signal that meets the first condition is not the first signal and / or the second signal that is repeatedly sent, and this method is because the transmission of the first signal and / or the second signal is more important;

[0142] The first condition may include a combination of one or more of the following:

[0143] o Any time unit and / or frequency domain unit where the first signal and / or the second signal is located overlaps or collides with any time unit and / or frequency domain unit where the first downlink signal is located;

[0144] o Any time unit and / or frequency domain unit of the protection band where the first signal and / or the second signal is located overlaps or collides with any time unit and / or frequency domain unit where the first downlink signal is located;

[0145] o Any time unit and / or frequency domain unit in the frequency band or carrier allocated to the first signal and / or the second signal overlaps or collides with any time unit and / or frequency domain unit in which the first downlink signal is located;

[0146] o The first downlink signal includes at least one of the following: SSB, system information (SI) message, PSS, SSS, RSS, PBCH, LP-SS, LPWUS, CORESET, CORESET0, physical downlink control channel PDCCH and / or physical downlink shared channel PDSCH for scheduling and / or sending SIB, PDCCH and / or PDSCH for scheduling and / or sending control resource set 0 CORESET0, PDCCH and / or PDSCH for scheduling and / or sending message 2 MSG2 / message B MSGB, PDCCH and / or PDSCH for scheduling and / or sending paging, and PDCCH and / or PDSCH, PRS for scheduling and / or sending downlink small data transmission DL SDT signal;

[0147] The UE does not expect the time slot used for the first signal and / or the second signal transmission to be indicated as uplink or overlap with the uplink symbol determined according to the configuration. The second signal that does not overlap with the uplink symbol determined according to the configuration is numbered sequentially starting from zero from the second signal monitoring opportunity.

[0148] If the time slot used for transmission of the first signal and / or the second signal is indicated as uplink or overlaps with an uplink symbol determined according to the configuration, the resources corresponding to the overlapping time unit are not valid first signal and / or second signal resources.

[0149] When the first signal and / or the second signal overlaps or collides with the UL signal in all or part of the time units and / or frequency domain units, the behavior of the UE may include a combination of one or more of the following:

[0150] o If the transmission of the first signal and / or the second signal and / or the first / second signal includes any time unit and / or frequency unit including the guard band and the physical random access channel (PRACH)

[0151] When an overlap or collision occurs in any time unit and / or frequency domain unit within a predefined or preconfigured time unit interval before and / or after a PRACH-related signal such as MSG1 and / or MSG3 and / or MSG A, or a PRACH-related signal, the time unit and / or frequency domain unit where the overlap or collision occurs is not a valid first signal and / or second signal resource, and / or the UE expects to send a PRACH-related signal such as MSG1 and / or MSG3 and / or MSG A, and the UE does not expect to receive or monitor the first signal and / or the second signal. Optionally, when the second signal is used to wake up a group of UEs, the UE expects to send a PRACH-related signal such as MSG1 and / or MSG3 and / or MSG A, and does not expect to receive or monitor the second signal. This operation is because the PRACH-related signal is more important than the second signal,

[0152] This is particularly applicable when the second signal is a repeatedly sent second signal.

[0153] o If any time unit and / or frequency domain unit including the transmission of the second signal and / or the second signal including the guard band overlaps or collides with any time unit and / or frequency domain unit of a PRACH-related signal such as MSG1 and / or MSG3 and / or MSG A, or a predefined or preconfigured time unit interval before and / or after a PRACH-related signal, when the second signal is used to wake up a group of UEs, the UE expects to receive or monitor the second signal, and the UE does not expect to send PRACH-related signals such as MSG1 and / or MSG3 and / or MSG A. This operation is because the second signal is used to wake up one or more UEs in a group of UEs. If the second signal is discarded, the wake-up signal of a group of UEs will be missed. At this time, it is considered that receiving the second signal of a group of UEs is more important than sending PRACH by one UE.

[0154] o If any time unit and / or frequency domain unit of the transmission of the first signal and / or the second signal and / or the first / second signal including the guard band overlaps or collides with the sounding reference signal (SRS) in any time unit and / or frequency domain unit, when the first signal is used to wake up a group of UEs, the UE expects to receive or monitor the first signal and / or the second signal, and the UE does not expect to send the SRS. This operation is because receiving the first signal and / or the second signal of a group of UEs is more important than sending the SRS by one UE.

[0155] o If any time unit and / or frequency domain unit including the transmission of the first signal and / or the second signal and / or the first / second signal including the guard band overlaps or collides with the SRS in any time unit and / or frequency domain unit, any time unit and / or frequency domain unit where the overlap or collision occurs

[0156] Or the frequency domain unit is not a valid first signal and / or second signal resource, and / or the UE sends an SRS, and the UE does not expect to receive or monitor the first signal and / or the second signal. This operation is applicable when the first signal and / or the second signal is a repeatedly sent first signal and / or the second signal.

[0157] o If any time unit and / or frequency domain unit including the guard band for transmitting the second signal and / or the second signal overlaps or collides with the UL SDT in any time unit and / or frequency domain unit, when the second signal is used to wake up a group of UEs, the UE does not send the UL SDT, and / or the UE expects to receive or monitor the second signal. At this time, although the UE sending the SDT no longer needs to receive or monitor the second signal, since the second signal is used to wake up one or more UEs in the group of UEs, it is considered that receiving the second signal of the group of UEs is more important than sending the UL SDT by one UE.

[0158] o If any time unit and / or frequency domain unit including the protection band for transmitting the first signal and / or the second signal and / or the first / second signal overlaps or collides with the UL SDT in any time unit and / or frequency domain unit, any time unit and / or frequency domain unit where the overlap or collision occurs is not a valid first signal and / or second signal resource, the UE does not expect to receive or monitor the first signal and / or the second signal, and / or the UE expects to send the UL SDT. This operation is applicable when the first signal and / or the second signal is a first signal and / or the second signal that is transmitted repeatedly.

[0159] In some embodiments, examples of group WUS are described.

[0160] The second signal for waking up may include a synchronization part and / or a data part. The synchronization part may be used to further reduce the impact of time-frequency and phase offset, and the data part may carry specific indication information of some UE groups. The common second signal is a special embodiment of the second signal, which can be used to wake up UE or multiple UE groups in the entire cell.

[0161] The UE grouping method of the second signal may include a combination of one or more of the following:

[0162] o Subgroup specified by the core network. The UE is assigned a subgroup index (between 0 and 7) based on the NAS signaling from the AMF, and based on the determined association between the second signal and the subgroup index, the second signal instructs the UE belonging to the subgroup index to monitor its related PO.

[0163] o Grouping based on UE index. The subgroup index of the UE is implicitly indicated, for example, the subgroup index of the UE is equal to (floor(UE_ID / (N*Ns))mod subgroupsNumForUEID)+

[0164] (subgroupsNumPerPO-subgroupsNumForUEID), where floor represents the lower bound of the rounding, UE_ID is equal to S-TMSI mod X, S-TMSI is the temporary UE identification number, X is a predefined value, N is the total number of paging frames with a duration of T, Ns is the number of POs in a paging frame, subgroupsNumPerPO represents the number of subgroups based on core network specified grouping and UE_ID grouping in a PO, and subgroupsNumForUEID represents the number of subgroups based on UE_ID in a PO. Based on the determined association between the second signal and the subgroup index, the second signal indicates that the UE belonging to the subgroup index monitors its related PO. Wherein T is determined by the shortest value among the UE-specific DRX values, and T is a real number greater than 0.

[0165] o The association relationship between the second signal and the subgroup index may be determined by a combination of one or more of the following:

[0166] The physical signal sequence generated by the second signal implicitly includes a UE subgroup index or a second signal resource index associated with the UE subgroup index; optionally, if there are multiple second signal resources, the association relationship between each second signal resource and the UE subgroup may be configured by RRC signaling, high-layer signaling, or SIB;

[0167] The length of the data portion of the second signal may be the number of POs associated with the second signal multiplied by the number of subgroups corresponding to each PO, wherein each bit of the data portion corresponds to a group of UE subgroup indexes, and when the information bit corresponding to the subgroup index is indicated as '1'

[0168] , the UEs in the UE subgroup wake up and monitor the associated PO. Otherwise, that is, when the information bit corresponding to the subgroup index indicates '0', the UEs in the UE subgroup do not monitor the associated PO. Figure 8 shown.

[0169] The UE supporting the second signal grouping may be configured to monitor the second signal and / or the common second signal, wherein the association relationship between the common second signal and the UE subgroup may include a combination of one or more of the following:

[0170] o The common second signal corresponds to all UEs in the cell, and the common second signal is used to wake up all UEs in the cell;

[0171] o The common second signal has a certain association relationship with all UE subgroups associated with the PO,

[0172] The common second signal is used to wake up all UE subgroups associated on the PO;

[0173] o The common second signal may be determined by a combination of one or more of the following:

[0174] The physical signal sequence generated by the second signal n implies the UE subgroup index; optionally, when the UE subgroup index is 0, it indicates that the generated second signal is a common second signal;

[0175] nWhen the second signal does not include or is not configured with a data portion, the second signal is a common second signal;

[0176] If the UE can support PEI and the second signal and is configured with PEI and the second signal, the UE's behavior may include a combination of one or more of the following:

[0177] o The UE only monitors the second signal and does not monitor the PEI. Optionally, if the second signal supports second signal grouping, the UE only monitors the second signal and does not monitor the PEI. At this time, the second signal indicates whether the UEs in the UE group need to be awakened to monitor the PO associated with the second signal, or directly establish an RRC connection.

[0178] oIf the second signal is a common second signal, and / or the second signal does not support UE grouping, the UE will monitor the PEI opportunity after waking up, and determine whether to wake up and monitor the associated PO based on the monitoring result of the PEI. When the UE is awakened by receiving the common second signal, the UE needs to monitor the PO associated with the second signal. At this time, no UE-specific PDCCH may be sent, and this monitoring method will bring additional power loss. If the UE continues to monitor the PEI opportunity after receiving the common second signal and being awakened, the PEI can indicate whether the UE needs to monitor the corresponding PO, which can reduce the power loss of the UE monitoring the PO not associated with the PEI.

[0179] The UE assumes that no more than one second signal sequence (second signal or common second signal) is sent on each second signal resource within a given time. The behavior of the UE or UE subgroup monitoring the second signal for wake-up may include a combination of one or more of the following:

[0180] o When DRX or eDRX is used and the UE detects any one of the second signal and the common second signal, and / or the second signal indicates that the subgroup to which the UE belongs monitors its associated PO, the UE should wake up to monitor the next or associated PO.

[0181] oIf the UE or the UE group does not monitor the second signal or the second signal does not indicate that the subgroup to which the UE belongs monitors its associated PO, optionally, the UE not monitoring the second signal may be that the UE does not monitor the second signal within the maximum duration of the second signal or the second signal monitoring opportunity, the UE or the UE group does not need to monitor one or more subsequent POs, the UE is not awakened or continues to be in an ultra-low sleep state or a deep sleep state.

[0182] In some embodiments, examples of conditions for performing relaxed RRM measurements are described.

[0183] When the second condition is met, the MR of the UE may perform RRM measurement of the serving cell and / or neighboring cell and / or temporary cell by skipping the maximum number of consecutive DRX cycles of the serving cell measurement configured by RRC or a relaxed RRM measurement cycle. The second condition may include a combination of one or more of the following:

[0184] oWhen relaxed RRM measurements are enabled / activated by the network;

[0185] oWhen relaxed RRM measurements are disabled / deactivated by the network;

[0186] o If the reference cell selection reception level value (cell Selection RX level value, Srxlev) of the serving cell based on the first signal or SSB minus the Srxlev calculated based on the RSRP of the first signal or SSB is less than or equal to a predefined or (pre) configured fifth threshold value; optionally, after cell selection or cell reselection to a new cell, or if the Srxlev calculated based on the RSRP of the first signal or SSB minus the reference Srxlev of the serving cell based on the first signal or SSB is greater than or equal to 0, or if the relaxed listening principle is not met for a predefined or preconfigured duration, the UE shall set the reference Srxlev of the serving cell to the Srxlev calculated based on the RSRP of the first signal or SSB.

[0187] o When the Srxlev calculated by the RSRP and / or RSRQ measured by the UE based on the first signal or SSB is greater than or equal to a predefined or (pre) configured sixth threshold value, or when the cell selection quality value (cell Selection quality value, Squal) calculated by the UE based on the RSRP and / or RSRQ measured by the UE based on the first signal or SSB is greater than or equal to a predefined or (pre) configured seventh threshold value; or when the RSRP measured by the UE based on the first signal or SSB is greater than or equal to a predefined or (pre) configured eighth threshold value, or when the RSRQ measured by the UE based on the first signal or SSB is greater than or equal to a predefined or (pre) configured ninth threshold value;

[0188] o Within a preconfigured or predefined time unit, when the variation range of RSRP measured by the UE based on the first signal or SSB is less than or equal to the predefined or (pre) configured tenth threshold value, or when the variation range of RSRQ measured by the UE based on the first signal or SSB is less than or equal to the predefined or (pre) configured eleventh threshold value;

[0189] When relaxed RRM measurement is disabled / deactivated, the first signal can still be enabled or activated. The first signal can provide the MR with synchronization of timing / frequency offsets caused by up to num DRX cycles or PO synchronization failures, where num can be a fixed or configurable parameter value determined according to the length of the DRX cycle or the length of the PTW, num is a real number greater than 0, can be a power of 2, and num is configured through SIB configuration or cell-specific RRC message configuration.
