Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communications, and more specifically, to wake-up signal related configuration and / or monitoring. BACKGROUND

[0002] To meet the demand for wireless data traffic having increased since deployment of 4G communication systems, efforts have been made to develop an improved 5G or pre-5G communication system. Therefore, the 5G or pre-5G communication system is also called a 'Beyond 4G Network' or a '5G Network'.

[0003] The 5G communication system is implemented to be connected to a next-generation Internet network so as to survive a beyond 4G mobile communication technology. For the 5G communication system, technologies of a high frequency band (mmWave), e.g., 60 GHz band, are developed to implement a high speed and large capacity of a wireless communication system. For the high frequency band technology, technologies of beamforming, massive MIMO, full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, etc. are developed.

[0004] In addition, for the 5G communication system, technologies of achieving a high data rate beyond 4G long term evolution (LTE) are developed, such as advanced coding modulation (ACM), hybrid FSK and QAM modulation (FQAM), and sliding window superposition coding (SWSC), and technologies of achieving a high frequency efficiency such as filter bank multi-carrier (FBMC), orthogonal frequency division under carrier (OFDM), and discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM).

[0005] In the 5G system, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) as an advanced coding modulation (ACM), and filter bank multi carrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA) as an advanced access technology have been developed.

[0119] Various embodiments of the present disclosure can be applied to various communication systems such as a global system for mobile communications (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) system, a general packet radio service (GPRS), a long term evolution (LTE) system, a frequency division duplex (FDD) system, a time division duplex (TDD), a universal mobile telecommunications system (UMTS), a worldwide interoperability for microwave access (WiMAX) communication system, a 5th generation (5G) system or a new radio (NR), etc. In addition, various embodiments of the present disclosure can be applied to future-oriented communication technologies.

[0120] Figure 1 An example wireless network 100 according to various embodiments of the present disclosure is illustrated. Figure 1 The embodiments of the wireless network 100 shown in FIG. 1 are for illustration only. Other embodiments of the wireless network 100 could be used without departing from the scope of the present disclosure.

[0121] The wireless network 100 includes a gNodeB (gNB) 101, a gNB 102, and a gNB 103. The gNB 101 communicates with the gNB 102 and the gNB 103. The gNB 101 also communicates with at least one Internet Protocol (IP) network 130, such as the Internet, a proprietary IP network, or other data network.

[0122] Depending on the network type, other well-known terms can be used instead of "gNodeB" or "gNB," such as "base station" or "access point." For the purposes of this patent document, the terms "gNodeB" and "gNB" are used to refer to the network infrastructure components that provide wireless access to remote terminals. Also, depending on the network type, other well-known terms can be used instead of "user equipment" or "UE," such as "mobile station," "subscriber station," "remote terminal," "wireless terminal," or "user device." For the purposes of this patent document, the terms "user equipment" and "UE" are used to refer to remote wireless equipment that wirelessly accesses a gNB, whether the UE is mobile (such as a mobile telephone or smartphone) or generally considered fixed (such as a desktop computer or vending machine).

[0123] The gNB 102 provides wireless broadband access to the network 130 for multiple first user equipment devices (UEs) within a coverage area 120 of the gNB 102. The multiple first UEs include a UE 111, which can be located in a small business (SB); a UE 112, which can be located in an enterprise (E); a UE 113, which can be located in a WiFi hotspot (HS); a UE 114, which can be located in a first residence (R); a UE 115, which can be located in a second residence (R); and a UE 116, which can be a mobile device (M), such as a cell phone, a wireless laptop, a wireless PDA, or the like. The gNB 103 provides wireless broadband access to the network 130 for multiple second UEs within a coverage area 125 of the gNB 103. The multiple second UEs include the UE 115 and the UE 116. In some embodiments, one or more of the gNBs 101-103 can communicate with each other and with the UEs 111-116 using 5G, long term evolution (LTE), LTE-A, WiMAX, or other advanced wireless communication techniques.

[0124] Dotted lines show the approximate extents of the coverage areas 120 and 125, which are shown as approximately circular for the purposes of illustration and explanation only. It should be clearly understood that the coverage areas associated with gNBs, such as the coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration and layout of the gNBs and the surrounding

[0125] As described in more detail below, one or more of the gNBs 101, 102, and 103 include a 2D antenna array as described in embodiments of the disclosure. In some embodiments, one or more of the gNBs 101, 102, and 103 support codebook design and structure for systems with 2D antenna arrays.

[0126] AlthoughFigure 1 One example of a wireless network 100 is shown, but Figure 1 various changes can be made. For example, wireless network 100 could include any number of gNBs and any number of UEs in any suitable arrangement. Also, gNB 101 could communicate directly with any number of UEs and provide those UEs access to network 130. Similarly, each gNB 102-103 could communicate directly with network 130 and provide UEs access to network 130. Further, gNBs 101, 102, and / or 103 could provide access to other or additional external networks, such as external telephone networks or other types of data networks.

[0127] Figure 2a and Figure 2b An example wireless transmit and receive path is shown according to this disclosure. In the following description, the transmit path 200 can be described as implemented in a gNB (such as gNB 102), and the receive path 250 can be described as implemented in a UE (such as UE 116). However, it is contemplated that the receive path 250 can be implemented in a gNB and the transmit path 200 can be implemented in a UE. In some embodiments, the receive path 250 is configured to support codebook design and structure for systems with 2D antenna arrays as described in embodiments of the disclosure.

[0128] The transmit path 200 includes a channel coding and modulation block 205, a serial-to-parallel (S-to-P) block 210, a size N inverse fast Fourier transform (IFFT) block 215, a parallel-to-serial (P-to-S) block 220, a cyclic prefix addition block 225, and an up-converter (UC) 230. The receive path 250 includes a down-converter (DC) 255, a cyclic prefix removal block 260, a serial-to-parallel (S-to-P) block 265, a size N fast Fourier transform (FFT) block 270, a parallel-to-serial (P-to-S) block 275, and a channel decoding and demodulation block 280.

[0129] In the transmit path 200, channel coding and modulation block 205 receives a set of information bits, applies coding (such as a low-density parity check (LDPC) coding), and modulates the input bits (such as with 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 de-multiplexes) the serial modulated symbols to parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points. The N-point IFFT block 215 performs an IFFT operation on the N parallel symbol streams to generate time-domain output signals. The parallel-to-serial (P-to-S) 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 to 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 the RF frequency.

[0130] The RF signal from the gNB 102 arrives at the UE 116 after passing through the wireless channel, and the reverse operations to those performed at the gNB 102 are performed at the UE 116. The down-converter 255 down-converts the received signal to baseband frequency and the remove cyclic prefix block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. The serial-to-parallel block 265 converts the time-domain baseband signal to parallel time-domain signals. The N-point FFT block 270 performs the FFT algorithm to generate N parallel frequency-domain signals. The parallel-to-serial block 275 converts the parallel frequency-domain signals to a sequence of modulated data symbols. The channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0131] Each of the gNBs 101-103 can implement a transmit path 200 similar to that described in connection with the example of Fig. 2A to transmit on the downlink to the UEs 111-116 and can implement a receive path 250 similar to that described in connection with the example of Fig. 2B to receive on the uplink from the UEs 111-116. Similarly, each of the UEs 111-116 can implement a transmit path 200 to transmit on the uplink to the gNBs 101-103 and can implement a receive path 250 to receive on the downlink from the gNBs 101-103.

[0132] Figure 2a and each of the components in Figure 2b may be implemented solely using hardware, or using a combination of hardware and software / firmware. As a particular example, Figure 2a and Figure 2bAt least some of the components in the diagram can be implemented in software, while others can be implemented by configurable hardware or a mixture of software and configurable hardware. For example, the FFT block 270 and the IFFT block 215 can be implemented as configurable software algorithms, where the value of the number of points N can be modified depending on the implementation.

[0133] Furthermore, although described as using FFT and IFFT, this is illustrative only and should not be construed as limiting the scope of the disclosure. Other types of transforms can be used, such as discrete Fourier transform (DFT) and inverse discrete Fourier transform (IDFT) functions. It will be appreciated that for DFT and IDFT functions, the value of the variable N can be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of the variable N can be any integer that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0134] Although Figure 2a and Figure 2b various changes can be made to the example wireless transmit and receive path shown. Figure 2a and Figure 2b various components in the Figure 2a and Figure 2b can be combined, further subdivided, or omitted and additional components can be added according to particular needs. Also, Figure 2a and Figure 2b are intended to show 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 communication in a wireless network.

[0135] Figure 3a An example UE 116 according to this disclosure is shown. Figure 3a The embodiment of the UE 116 shown in Figure 1 The UEs 111-115 of can have the same or similar configuration. However, UEs have a wide variety of configurations, and thus Figure 3a the scope of the disclosure is not limited to any particular implementation of a UE.

[0136] The UE 116 includes antennas 301, radio frequency (RF) transceiver 302, transmit (TX) processing circuitry 303, microphone 304, and receive (RX) processing circuitry 305. The UE 116 also includes a speaker 306, a controller / processor 307, an input / output (I / O) interface 308, input device(s) 309, a display 310, and a memory 311. The memory 311 includes an operating system (OS) 312 and one or more applications 313.

[0137] The RF transceiver 302 receives, from the antenna 301, an incoming RF signal transmitted by a gNB of the wireless network 100. The RF transceiver 302 down-converts the incoming RF signal to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to the RX processing circuitry 305, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. The RX processing circuitry 305 transmits the processed baseband signal to the speaker 306 (such as for voice data) or to the controller / processor 307 (such as for web browsing data) for further processing.

[0138] The TX processing circuitry 303 receives analog or digital voice data from the microphone 304 or other outgoing baseband data (such as web access data, e-mail, or interactive video game data) from the controller / processor 307. The TX processing circuitry 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 302 receives the outgoing processed baseband or IF signal from the TX processing circuitry 303 and up-converts it into an RF signal for transmission via the antenna 301.

[0139] The controller / processor 307 can include one or more processors or other processing devices and execute instructions stored in memory 311 to control the overall operation of the UE 116. For example, the controller / processor 307 could control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceiver 302, the RX processing circuitry 305, and the TX processing circuitry 303 in accordance with well-known principles. In some embodiments, the controller / processor 307 includes at least one microprocessor or microcontroller.

[0140] The controller / processor 307 can also execute other processes and programs resident in memory 311, such as operations for channel quality measurement and reporting for systems with 2D antenna arrays as described in the embodiments of the present disclosure. The controller / processor 307 can move data into or out of memory 311 as required by the processes executing on the controller / processor 307 and / or as required by the processes performed by the controller / processor 307. In some embodiments, the controller / processor 307 is configured to execute the application programs 313 based on the OS 312 or in response to signals received from gNBs or an operator. The controller / processor 307 is also coupled to the I / O interface 308, which provides the UE 116 with the ability to connect to other devices such as laptop computers and handheld computers. The I / O interface 308 is the communication path between these accessories and the controller / processor 307.

[0141] The controller / processor 307 is also coupled to the input device 309 and the display 310. The operator of the UE 116 can use the input device 309 to enter data into the UE 116. The display 310 can be a liquid crystal display or other display capable of rendering text and / or at least limited graphics, such as from web sites. The memory 311 is coupled to the controller / processor 307. The memory 311, can include both random access memory (RAM) and

[0142] Although Figure 3a various changes can be made to Figure 3a For example, Figure 3a various components in the Figure 3a controller / processor 307 can be divided, further subdivided, or omitted, and additional components can be added according to particular needs. As a particular example, the controller / processor 307 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Also, while the

[0143] Figure 3b An example gNB 102 according to this disclosure is shown. Figure 3b The embodiment of the gNB 102 shown in Figure 1 other gNBs of Figure 3b However, gNBs come in a wide variety of configurations, and

[0144] As Figure 3b shown in FIG. 1C, the 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. The gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0145] RF transceivers 372a-372n receive incoming RF signals, such as signals transmitted by the UE or other gNBs, from antennas 370a-370n. RF transceivers 372a-372n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 376, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. RX processing circuitry 376 sends the processed baseband signals to controller / processor 378 for further processing.

[0146] 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. RF transceivers 372a-372n receive the outgoing processed baseband or IF signal from the TX processing circuit 374 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 370a-370n.

[0147] The controller / processor 378 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 may control the reception of forward channel signals and the transmission of reverse channel signals via RF transceivers 372a-372n, RX processing circuitry 376, and TX processing circuitry 374, according to known principles. The controller / processor 378 may also support additional functions, such as more advanced wireless communication functions. For example, the controller / processor 378 may perform a BIS process, such as by a blind interference sensing (BIS) algorithm, and decode the received signal after subtracting interference. The controller / processor 378 may support any of a wide variety of other functions in the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0148] The controller / processor 378 is also capable of executing programs and other processes, such as a basic operating system, residing in the memory 380. The controller / processor 378 is also capable of supporting channel quality measurement and reporting for systems having 2D antenna arrays as described in embodiments of this disclosure. In some embodiments, the controller / processor 378 supports communication between entities such as web RTCs. The controller / processor 378 is capable of moving data into or out of the memory 380 as needed for the execution of processes.

[0149] 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 over a network. The backhaul or network interface 382 is capable of supporting communication via any suitable wired or wireless connection(s). 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 technologies or NR, LTE, or LTE-A), the backhaul or network interface 382 allows 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 allows 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 architecture supporting communication via a wired or wireless connection, such as an Ethernet or RF transceiver.

[0150] Memory 380 is coupled to controller / processor 378. A portion of memory 380 may include RAM, while another portion may include flash memory or other ROM. In some embodiments, multiple instructions, such as a BIS algorithm, are stored in memory. The multiple instructions are configured to cause 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.

[0151] As described in more detail below, the transmit and receive paths of the gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuitry 374, and / or RX processing circuitry 376) support aggregated communication with FDD and TDD cells.

[0152] although Figure 3b An example of gNB 102 is shown, but more can be found on... Figure 3b Various modifications can be made. For example, gNB102 can include any number of... Figure 3a Each component shown. As a specific example, an access point can include multiple backhaul or network interfaces 382, ​​and a controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as a single instance including TX processing circuitry 374 and a single instance including RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0153] The time domain unit (also referred to as time unit) in this application can be: one OFDM symbol, one OFDM symbol group (composed of multiple OFDM symbols), one time slot, one time slot group (composed of multiple time slots), one subframe, one subframe group (composed of multiple subframes), one system frame, one system frame group (composed 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. It can also be the time length of one OOK chip.

[0155] Exemplary embodiments of the present disclosure are further described below in conjunction with the accompanying drawings.

[0156] The text and drawings are provided only as examples to help the reader understand the present disclosure. They are not intended to, and should not be interpreted to, limit the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, it will be apparent to those skilled in the art based on the disclosure herein that modifications can be made to the embodiments and examples without departing from the scope of the present disclosure.

[0157] The transmission link of the wireless communication system mainly includes: a downlink communication link from a 5G new radio (New Radio, NR) gNB to a user equipment (User Equipment, UE), an uplink communication link from the UE to the network, and a sidelink communication link from the UE to the UE.

[0158] In a wireless communication system, for example, in the current wireless communication system, in order to reduce the energy consumption of the terminal side, a discontinuous reception (DRX) mechanism is introduced. In the RRC inactive state and / or idle state, the DRX cycle is equal to the paging cycle, and the UE listens to a paging occasion (PO) in each DRX cycle. Most of the time in each DRX cycle is in a sleep state and does not need to listen to the PDCCH except for the paging occasion. When the UE listens to the P-RNTI scrambled PDCCH in the corresponding PO, the UE continues to read the terminal identifier paged in the paging message. If the read terminal identifier and its own identifier are the same, 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 listen to the corresponding PO. If the system information is configured with PEI, the UE monitors the PEI occasion in each DRX cycle. If the UE detects the PEI indication and the PEI indicates that the UE listens to the associated PO, the UE should wake up to listen to the PO; otherwise, the UE does not need to wake up to listen to the PO.

[0159] In some use cases (such as Internet of Things devices and / or wearable devices) with more stringent requirements for UE low energy consumption, in order to further prolong the battery life of the UE, the wireless communication system can use a lower power wake-up signal (such as a new low power wake-up signal (LPWUS)) to wake up the UE. Therefore, it is necessary to improve the configuration and / or listening process of the wake-up signal (such as LPWUS).

[0160] In the following description, for the convenience of description, LPWUS is taken as an example of the wake-up signal. It should be understood that this is only exemplary, and the embodiments of the present disclosure also relate to other names of wake-up signals, or the wake-up signal can also include other types of wake-up signals.

[0161] Exemplarily, in the present disclosure, a method and device for low-power wake-up signal configuration and monitoring are introduced. In an embodiment of the present disclosure, the method according to the present disclosure is applied in at least one of the following aspects: a method for determining a sub-group set, a time-domain location of LPWUS monitoring, a method for determining a sub-group index in an associated sub-group set, an enabling condition and an exit condition of LPWUS monitoring, and a UE behavior when an enabling condition of RRM measurement offloading (for example, offloading to a wake-up signal receiving module) is different from an enabling condition of LPWUS monitoring. As mentioned above, in the embodiments of the present disclosure, a wake-up signal is exemplarily introduced, wherein the wake-up signal includes but is not limited to an LPWUS signal, and the method introduced can also be used for configuration and transmission of other signals.

[0162] The receiver of the UE includes two modules, one is a main radio module (MR) for receiving a regular signal / channel transmitted by the base station, and the other is a lower power wake-up signal receiving module (LPWUR) for receiving a wake-up signal transmitted by the base station. The wake-up signal is received by using a dedicated module because the LPWUS is a waveform based on amplitude shift keying (ASK) modulation on the basis of the existing NR system based on orthogonal frequency division multiplexing (OFDM) waveform. The LPWUR can monitor the wake-up signal at a very low power. Once the UE monitors the wake-up signal, the LPWUR can trigger the MR to switch from a sleep period to an active period to monitor the PEI and / or the PO. Optionally, on-off keying (OOK) modulation is a special case of amplitude shift keying (ASK) modulation. The LPWUR includes two types of receivers: an OOK-based receiver and an OFDM-based receiver. The OOK-based receiver performs synchronization and RRM measurement based on the LP-SS, and the OFDM-based receiver performs synchronization and RRM measurement based on the SSB.

[0163] Figure 4 An example flowchart of a method performed by a user equipment (UE) according to an embodiment of the present disclosure is shown. According to the method of the present disclosure, a wake-up signal group and a monitoring resource (for example, a monitoring occasion (MO) of the wake-up signal) can be determined according to the UE capability. Figure 4

[0164] As shown in Figure 4 , the method includes steps 401-404:

[0165] Step 401: receiving configuration information related to a wake-up signal for waking up the UE, wherein the configuration information includes configuration information of a wake-up signal occasion and a wake-up signal monitoring occasion associated with receiving one wake-up signal;

[0166] ​Step 402: determining the UE-associated wake-up signal sub-group set index based on the UE capability related to the wake-up latency supported by the UE;

[0167] Step 403: determining the LP-WUS sub-group set index and / or the sub-group index of the UE in the sub-group set based on the determined sub-group set index, and determining the time-domain location of the LP-WUS according to the association between the sub-group index and the MO resource and the configuration information;

[0168] Step 404: monitoring the wake-up signal based on the determined time-domain location of the wake-up signal monitoring occasion, and if the code word indicated by the detected wake-up signal contains the UE sub-group index, the UE is woken up to monitor the paging message, and if the code word indicated by the detected wake-up signal does not contain the UE sub-group index, the UE monitors the LP-WUS according to the configured LP-WUS period. Optionally, the method can further include step 401-1: the UE reports the supported wake-up latency through the UE capability.

[0169] It should be understood that, in the present disclosure, the description of the wake-up signal sub-group set is used for convenience of description, but this name is only exemplary, and other names can also be used, such as wake-up signal group set, LP-WUS group set, LP-WUS sub-group set, LP-WUS set, wake-up signal set, etc.

[0170] The technical solutions of the present disclosure will be described in more detail below in combination with exemplary embodiments.

[0171] In one aspect, a method for determining the LP-WUS sub-group set and the time-domain location of the monitoring will be introduced.

[0172] In one embodiment, the UE reports the supported wake-up latency through the UE capability, and optionally, the wake-up latency can be one or more wake-up latencies selected from X candidate values, the wake-up latency being the minimum time interval from the reception of the wake-up signal to the monitoring of the PDCCH. Wherein, X can be pre-configured or pre-defined, and X is an integer greater than 1. For example, X can be equal to 2, and this operation is to support two wake-up latencies for the UE in the super-deep sleep state and the deep sleep state to wake up the MR to monitor the PDCCH, and optionally, the two wake-up latencies can be 400ms and 20ms respectively. For another example, X can be equal to 3, and this operation is to support two UE capabilities for the UE in the super-deep sleep state to wake up the MR to monitor the PDCCH and different wake-up latencies for the UE in the super-deep sleep state and the deep sleep state to wake up the MR to monitor the PDCCH, and optionally, the three wake-up latencies can be 800ms, 400ms and 20ms respectively.

[0173] In an embodiment, a wake-up signal occasion (e.g., LPWUS Occasion, LO) can be associated with one or more paging occasions (POs), and the one or more POs associated with the LO correspond to a UE group, and to reduce the paging latency for the UEs in the UE group that are in deep sleep (e.g., with a wake-up latency of 20 ms), the UEs in the UE group can be further divided into subgroups, and the UEs with the same wake-up latency can be grouped into the same set of subgroups. The total number of the sets of subgroups can be equal to the number of candidate values of the wake-up latency.

[0174] In an embodiment, a UE can obtain the configuration information of the LO and the configuration information of the wake-up signal monitoring occasions (MOs) through a system information block (SIB) message, wherein each of the LOs can contain a plurality of wake-up signal MOs, and the UE can monitor the wake-up signal in K*N consecutive MOs or K*N non-consecutive MOs, K is the number of MOs in the same beam direction that transmit the same and / or different wake-up signal information bits, and N is the number of beams of the wake-up signal that establish a quasi co-location (QCL) relationship with the SSB or the LP-SS. K and N are predefined or preconfigured values, and K and N are integers greater than or equal to 1. The configuration information of the LO contains at least one of the following parameters: the minimum time interval from the end position or the start position of the LO to the start of the one or more POs associated with the LO, wherein the start of the plurality of POs is the start of the first PO in the plurality of POs; the duration of the LO, and optionally, the duration can be the maximum duration of the LO. If the UE receives the wake-up signal after the maximum duration of the LO, the UE is not expected to monitor the associated one or more POs. The configuration information of the wake-up signal MOs contains at least one of the following parameters: the interval between the first wake-up signal MO and the start of the LO, the interval between two adjacent wake-up signal MOs, the duration of the wake-up signal MO, the interval between the first wake-up signal MO and the start or end position of each set of wake-up signal subgroups, and the number or length of the MOs associated with each set of wake-up signal subgroups.

[0175] The configuration information of the LO further includes at least one of the following parameters:

[0176] The first offset from the start position of the LO to the start of the radio frame in which the one or more POs associated with the LO are located, wherein the start of the radio frame in which the plurality of POs are located is the start of the radio frame in which the first PO in the plurality of POs is located. The first offset is the number of radio frames;

[0177] In one embodiment, if the UE reports one supported wake-up latency, the UE determines the index of the associated wake-up signal sub-group set according to the reported one wake-up latency. Alternatively, according to the predefined or pre-configured correspondence between wake-up latency and wake-up signal sub-group set index, e.g., according to the definition of Table 1, the UE can determine the index of the wake-up signal sub-group set according to the UE capability of the reported one wake-up latency. According to the predefined or pre-configured correspondence between wake-up latency and wake-up signal sub-group set index, the method of the UE to determine the associated wake-up signal sub-group set can further comprise one or more of the following in combination:

[0178] o If the UE does not report supported wake-up latency, the UE determines the index of the associated wake-up signal sub-group set according to the maximum value among the candidate values of more than one supported wake-up latency.

[0179] o If the UE does not report supported wake-up latency, the network does not configure the wake-up signal sub-group set associated with one or more UE capabilities supported by the UE, the UE does not monitor the wake-up signal. If the UE does not receive the wake-up signal within a predefined or pre-configured duration, the UE wakes up to monitor the PEI or periodically monitors the PO, and re-reports the UE capability.

[0180] o If the UE does not report supported wake-up latency, the network configures the wake-up signal sub-group set associated with one or more UE capabilities supported by the UE, the UE determines the index of the wake-up signal sub-group set as the maximum wake-up latency associated wake-up signal sub-group set in the intersection of the wake-up signal sub-group set associated with one or more wake-up latency supported by the UE and the wake-up signal sub-group set associated with one or more wake-up latency configured by the network.

[0181] o If the UE reports supported wake-up latency, but the network does not configure the wake-up signal sub-group set associated with the UE reported UE capability, the UE determines the index of the wake-up signal sub-group set as the maximum wake-up latency associated wake-up signal sub-group set in the intersection of the wake-up signal sub-group set associated with one or more wake-up latency supported by the UE and the wake-up signal sub-group set associated with one or more wake-up latency configured by the network.

[0182] In one embodiment, the UE determines the starting position of the LO according to the starting position of the first paging frame in which the first PO of the one or more POs associated with the LO is located and the first offset, determines the ending position of the wake-up signal LO or the wake-up signal MO expected to be monitored according to the starting position of the PO associated with the UE and the one wake-up latency reported by the UE, and / or the UE does not expect to monitor the wake-up signal MO after the time unit determined according to the starting position of the PO associated with the UE and the minimum wake-up latency reported by the UE, and / or the UE monitors the PO.

[0183] Table 1 Correspondence between wake-up latency and wake-up signal sub-group set index

[0184] Wake signal sub-group set index Wake up latency 1 800 ms 2 400 ms 3 20 ms

[0185] In an embodiment, more than one WUS subset set can be associated to one LO, and the UE can establish or obtain the association between the WUS subset set and the WUS transmission resource (e.g., the LO) to determine the time domain resource location to monitor the WUS. For example, according to the order of the size of the wake-up latency corresponding to the WUS subset set, the association includes that the first set of continuous K*N WUS MOs in the LO is associated with the WUS subset set 1, the second set of continuous K*N WUS MOs in the LO is associated with the WUS subset set 2, and so on, as shown in the following table. Figure 5 This way makes the user with larger wake-up latency associated to the WUS MOs in the LO earlier, and the user with smaller wake-up latency associated to the MOs in the LO closer to the start of the PO, which reduces the paging latency of the user with smaller wake-up latency. For example, assuming that the WUS subset set is 2, the network can configure the time interval from the end of the LO to the start of the PO to be max(T1-T2, T3) by implementing an algorithm, where T1 represents the first time interval from the end of the WUS MO corresponding to the WUS subset set 1 associated with larger wake-up latency to the start of the PO, the first time interval contains or is equal to the wake-up latency associated with the WUS subset set 1, T2 represents the second time interval from the end of the WUS MO corresponding to the WUS subset set 1 associated with larger wake-up latency to the end of the LO, the second time interval contains or is equal to the duration of the multiple continuous MOs associated with the WUS subset set 2 associated with smaller wake-up latency, and T3 represents the wake-up latency associated with the WUS subset set 2 associated with smaller wake-up latency.

[0186] In another embodiment, more than one WUS subset set can be associated to different LOs, for example, one WUS subset set corresponds to one LO, and the UE can establish or obtain the association between the WUS subset set and the WUS transmission resource (e.g., the LO) to determine the time domain resource location to monitor the WUS. For example, according to the order of the size of the wake-up latency corresponding to the WUS subset set, the association includes that the first LO is associated with the WUS subset set 1, the second LO is associated with the WUS subset set 2, and so on. This way makes the user with larger wake-up latency associated to the LO earlier, and the user with smaller wake-up latency associated to the LO closer to the start of the PO, which reduces the paging latency of the user with smaller wake-up latency.

[0187] In one alternative embodiment, the association between the wake-up signal subgroup set and the wake-up signal transmission resources includes the following: a wake-up signal subgroup set can be associated with non-contiguous MOs in the LO; in each of the N beam directions in the LO, the first group of K consecutive MOs is associated with wake-up signal subgroup set 1, the second group of K consecutive MOs is associated with wake-up signal subgroup set 2, and so on. Figure 6 As shown. This operation allows the UE to receive a wake-up signal on one beam and then no longer listen for subsequent MO signals on other beams, saving the UE's energy consumption from listening for wake-up signals.

[0188] In one alternative scheme, to mitigate the problem that an excessive number of associated subgroups within a single wake-up signal may prevent the information bits corresponding to all wake-up-related information for all subgroups, a wake-up signal subgroup set can be further divided into multiple subgroup subsets. Each subgroup subset corresponds to a wake-up signal. UEs within a subgroup subset listen for wake-up signals on associated resources. If the subgroup index indicated by the wake-up signal is the same as the UE's subgroup index, the UE is woken up to listen for the PO. If the subgroup index indicated by the wake-up signal is different from the UE's subgroup index, the UE continues to listen for wake-up signals according to the configured LO period. The association between the wake-up signal subgroup set, the wake-up signal subgroup subset, and the wake-up signal transmission resources includes: the first group of K*N consecutive wake-up signals MO in LO is associated with wake-up signal subgroup subset 1 in wake-up signal subgroup set 1; the second group of K*N consecutive wake-up signals MO is associated with wake-up signal subgroup subset 2 in wake-up signal subgroup set 1, and so on; the first group of K*N consecutive wake-up signals MO after M*K*N MO associated with wake-up signal subgroup set 1 in LO is associated with wake-up signal subgroup subset 1 in wake-up signal subgroup set 2; the second group of K*N consecutive wake-up signals MO after M*K*N MO associated with wake-up signal subgroup set 1 is associated with wake-up signal subgroup subset 2 in wake-up signal subgroup set 2, and so on. Here, M is the number of wake-up signal subgroup subsets within a wake-up signal subgroup set. Alternatively, the association between wake-up signal subgroup subsets and MO can be similar to... Figure 6 As shown in the diagram. For example, in each of the N beam directions in the LO, the first group of K consecutive MOs is associated with the first set of wake-up signal subgroups, the second group of K consecutive MOs is associated with the second set of wake-up signal subgroups, and so on; in each of the N beam directions in the LO, the first group of K consecutive wake-up signal MOs after the M*K MOs associated with wake-up signal subgroup 1 is associated with the first set of wake-up signal subgroups in wake-up signal subgroup 2, the second group of K consecutive wake-up signal MOs after the M*K MOs associated with wake-up signal subgroup 1 is associated with the second set of wake-up signal subgroups in wake-up signal subgroup 2, and so on.

[0189] In one embodiment, the MOs corresponding to two sets of adjacent wake-up signal sub-group sets in one LO are continuous, for example, the interval of any two adjacent wake-up signal MOs in one LO is equal. The UE can determine the starting position of the first MO in the LO according to the starting point of the configured LO and the interval between the first wake-up signal MO and the starting point of the LO, and determine the time domain position of the subsequent MO according to the starting position of the first MO and the duration of the wake-up signal MO, and the interval between the adjacent two wake-up signal MOs. Such operation can improve resource utilization efficiency while reducing user paging delay to a certain extent.

[0190] In an implementation, the start of the LO is the start of the radio frame where the LO is located, and the UE determines the starting position of the first MO based on the configured start of the LO and the configured interval between the first wake-up signal MO and the start of the LO, wherein the configured interval between the first wake-up signal MO and the start of the LO is the number of slots. In one LO, the starting position of the subsequent or next wake-up signal MO is determined based on the starting position or ending position of the previous wake-up signal MO and the configured interval between the previous wake-up signal MO and the subsequent or next wake-up signal MO. Optionally, the configured interval between the previous wake-up signal MO and the subsequent or next wake-up signal MO is the number of slots or OFDM symbols, the starting position of the wake-up signal MO is the starting position of the slot or OFDM symbol, and the duration of the configured wake-up signal MO is the number of slots or OFDM symbols. The UE can determine the valid / available wake-up signal OFDM symbol based on other signals and / or channels, which include but are not limited to SSB, CORESET / Type-0 CSS, TDD DL / UL configuration, cell-specific reference signal (CRS), and the other signals and / or channels are configured by SIB1. For example, in each wake-up signal MO, if the physical resource block where the wake-up signal is located or the physical resource block used for the wake-up signal transmission overlaps or collides with other signals and / or channels in the frequency domain resource, the OFDM symbol corresponding to the physical resource block where the wake-up signal is located or the physical resource block used for the wake-up signal transmission cannot be used for the wake-up signal transmission or is not a valid / available wake-up signal resource, wherein the physical resource block includes the guard interval. If the physical resource block where the wake-up signal is located or the physical resource block used for the wake-up signal transmission does not overlap or collide with other signals and / or channels in the frequency domain resource, and if the OFDM symbol where the wake-up signal is located or the OFDM symbol used for the wake-up signal transmission does not overlap or collide with other signals and / or channels in the time domain resource, the UE determines the OFDM symbol where the wake-up signal is located or the OFDM symbol used for the wake-up signal transmission as a valid / available wake-up signal OFDM symbol. This operation can enable the UE to determine the starting position of the first wake-up signal monitoring occasion only based on the configured start of the LO at the slot level and the configured interval between the first wake-up signal MO and the start of the LO, without the need to specify the starting OFDM symbol of the wake-up signal, the OFDM symbol where the wake-up signal is located or the OFDM symbol used for the wake-up signal transmission in each MO is a valid / available wake-up signal OFDM symbol, and the starting OFDM symbol of the wake-up signal in each MO is the first valid / available wake-up signal OFDM symbol in each MO, which can reduce the signaling overhead.Optionally, the number of valid / available wake-up signal OFDM symbols in each MO is the same, which is applicable to the case that the interval of one adjacent wake-up signal MO configured is the number of OFDM symbols, and / or the starting position of one wake-up signal MO is the starting position of OFDM symbols, and / or the duration of one wake-up signal MO configured is the number of OFDM symbols. Alternatively, the number of valid / available wake-up signal OFDM symbols in each MO is different, which is applicable to the case that the interval of one adjacent wake-up signal MO configured is the number of slots, and / or the starting position of one wake-up signal MO is the starting position of slots, and / or the duration of one wake-up signal MO configured is the number of slots.

[0191] In another optional solution, the UE can also determine the valid / available wake-up signal OFDM symbols based on the network configured time-domain pattern indication and / or other signals and / or channels configured. The duration of the time-domain pattern is equal to the maximum period of all the other signals and / or channels configured and / or other unicast signals and / or channels. The time-domain pattern can be a bitmap, each bit of the bitmap corresponds to whether the associated OFDM symbol is occupied. This operation can be that the UE determines the unoccupied OFDM symbols through the time-domain pattern, and determines the valid / available wake-up signal OFDM symbols based on the other signals and / or channels configured, through the resources occupied by the signals and / or channels of other users or the resources occupied by other unicast signals and / or channels. In another optional solution, the MOs corresponding to two adjacent wake-up signal sub-group sets in one LO can be discontinuous, for example, in one LO, the time interval from the end position of the last MO associated with each wake-up signal sub-group set to the starting position of the associated one or more POs is greater than or equal to the wake-up delay associated with the wake-up signal sub-group set, and the positions of the other MOs associated with each wake-up signal sub-group set can be continuous or discontinuous, the MOs associated with each wake-up signal sub-group set can be staggered with each other (for example, some of the MOs corresponding to a certain sub-group set are earlier than some of the MOs corresponding to another sub-group set, while some of the MOs are later than some of the MOs corresponding to another sub-group set), or can have a unified order (for example, all the MOs corresponding to a certain sub-group set are earlier than the MOs corresponding to another sub-group set). The time interval from the end position of the LO to the starting position of the associated one or more POs is greater than or equal to the minimum wake-up delay reported by the UE, which can further reduce the paging delay of users supporting shorter wake-up delay.

[0192] In an embodiment, the UE determines the sub-group index in the associated sub-group set by UE index (or UE ID), for example, the UE determines the sub-group index in the associated sub-group set as floor(UE_ID / (N*Ns))mod U, where N is the number of PFs in a DRX cycle, Ns is the number of POs in a PF, and U is the number of wake-up signal sub-groups in a sub-group set, where U is a pre-configured or pre-defined integer, U is greater than or equal to 1.

[0193] In an optional solution, the UE determines the index of the associated wake-up signal sub-group subset in the associated wake-up signal sub-group set by UE index (or UE ID). For example, the UE determines the index of the associated wake-up signal sub-group subset in the associated sub-group set as floor(UE_ID / (N*Ns*U))mod P, where P is a pre-configured or pre-defined integer, P is greater than or equal to 1. Optionally, P is equal to the number of associated wake-up signal sub-groups in a wake-up signal sub-group set divided by V and taking the upper bound, where V is the length of the maximum number of information bits supported by a wake-up signal in base 2, for example, if the maximum number of information bits supported by a wake-up signal is k bits, then V = 2 k , P = ceil(G / V), and G is the number of associated wake-up signal sub-groups in a wake-up signal sub-group set. The UE determines the index of the wake-up signal sub-group in the associated wake-up signal sub-group subset by UE index, for example, the UE determines the index of the wake-up signal sub-group in the associated wake-up signal sub-group subset as floor(UE_ID / (N*Ns*U*X))mod Q, where Q is the number of wake-up signal sub-groups in a sub-group subset, where Q is a pre-configured or pre-defined integer, Q is greater than or equal to 1. Optionally, Q is equal to V.

[0194] In an embodiment, if the interval between the end time unit of the one or more LOs and the start time unit of the associated PO is not less than the wake-up latency supported or reported by the UE, the UE monitors the one or more LOs associated with one or more offsets, the offset being the end position of the LO to the start position of the associated PO. The UE determines the end time unit of the associated one or more LOs by the start time unit of the PO and the one or more offsets configured. The one or more offsets are not less than the wake-up latency supported or reported.

[0195] In an optional solution, if the interval between the end time unit of the LO and the start time unit of the associated PO is less than the wake-up latency supported or reported by the UE, the UE monitors the PEI and / or periodically monitors the PO, and / or exits the wake-up signal monitoring procedure.

[0196] In an alternative, the UE monitoring one or more LOs associated with one or more offsets can comprise the UE monitoring all LOs greater than or not less than the wake-up latency supported or reported by the UE, and / or until receiving a UE-specific wake-up signal, and / or the earlier one. The UE-specific wake-up signal can comprise a wake-up signal carrying the index of the sub-group the UE belongs to or a wake-up signal waking up all sub-groups associated with the wake-up signal.

[0197] In an alternative, the UE monitoring one or more LOs associated with one or more offsets can comprise the UE monitoring the LO associated with the largest offset configured by the network, if the UE detects a wake-up signal and the wake-up signal indicates that the sub-group the UE belongs to is woken up, the UE is not expected to monitor the subsequent LO associated with the PO (the PO associated with the UE). If the UE does not detect a wake-up signal or the wake-up signal does not indicate that the sub-group the UE belongs to is woken up, and if the second largest offset configured by the network is greater than or not less than the wake-up latency supported or reported by the UE, the UE monitors the LO associated with the second largest offset configured by the network, if the UE detects a wake-up signal and the wake-up signal indicates that the sub-group the UE belongs to is woken up, the UE is not expected to monitor the subsequent LO associated with the PO (the PO associated with the UE). Similarly, the UE monitors the LO associated with the largest offset configured by the network, if the UE detects a wake-up signal and the wake-up signal indicates that the sub-group the UE belongs to is woken up, the UE is not expected to monitor the subsequent LO associated with the PO (the PO associated with the UE), and so on, until the offset associated with the LO is less than the wake-up latency supported or reported by the UE.

[0198] In an alternative, if the interval between the end time unit of each LO and the start time unit of the associated PO is less than the wake-up latency supported or reported by the UE, the UE monitors all configured LOs, when the UE detects a wake-up signal and the wake-up signal indicates that the sub-group the UE belongs to is woken up, the UE monitors the first PO satisfying the wake-up latency reported or supported by the UE. Alternatively, the interval between the end time unit of the LO and the start time unit of the associated PO being less than the wake-up latency supported or reported by the UE can comprise the interval between the end time unit of any one of the network configured LOs or all network configured LOs and the start time unit of the associated PO being less than the wake-up latency supported or reported by the UE.

[0199] In one embodiment, the UE obtains the number of subgroups SN per PO and / or the number of paging occasions LPON1 per LO association or the number of POs LPON2 per LO group association through RRC configuration, or the association between LO and PO is determined by the number of subgroups SN per PO in the configuration, for example, the UE determines the number of POs LPON1 per LO association as (maxSN / SN), or the UE determines the number of POs LPON2 per LO group association as floor((LON*maxSN) / SN), where LON is the number of LOs in one LO group configured by the base station, and LON is a pre-configured or pre-defined parameter value, LON is greater than or equal to 1. Optionally, if LON is not configured, the default LON = 1. The value of the PO index associated with one LO group is POI = ((UE_ID mod N)*Ns+i_s) mod LPON2. The value of the subgroup index associated with the LO is i_s = floor((POI*SN+i n , 0 < i n < SN, the UE determines the associated wakeup signal subgroup index as (POI*SN+i n ) mod maxSN, the UE determines the LO index in one LO group as floor((POI*SN+i n ) / maxSN), and the UE listens to the wakeup signal on the resource corresponding to the LO index in the associated LO group. If the UE listens to the wakeup signal and the value of the information bit carried by the wakeup signal is equal to the associated wakeup signal subgroup index or the information bit carried by the wakeup signal indicates all subgroups associated with the wakeup LO, the UE listens to the PO and / or does not expect to listen to the wakeup signal. Wherein the index of the PO is i_s = floor(UE_ID / N) mod Ns, UE_ID is the index calculated by the UE based on TMSI, N is the number of paging frames in one DRX cycle, Ns is the number of paging occasions in one paging frame, i n = floor(UE_ID / (N*Ns)) mod SN + (SN-SNU), and SNU is the number of subgroups in one PO based on UE_ID grouping, SNU is a pre-configured parameter value, and maxSN is a pre-defined or pre-configured value, such as 32.

[0200] In one implementation, if the number of subgroups SN of each PO is less than or equal to maxSN / q, where q is an integer greater than 1, one LO can be associated to LPON=floor(maxSN / SN) consecutive POs in one DRX cycle. For example, when q=2, one LO can be associated to two consecutive POs in one DRX cycle. Compared to one LO associated to one PO, for example, compared to 2 LO indications for 32 subgroups of 2 POs, this operation can use 1 LO indication for 32 subgroups of 2 POs, reducing the resource overhead of LO. The wakeup signal subgroup index is i n , the 0 < i < SN, the UE determines the associated wakeup signal subgroup index as (( (UE_ID mod N) * Ns + i_s) mod LPON) * SN + i n n

[0201] In one implementation, the UE obtains the number of POs LPON2 associated to one LO group and / or the number of LOs LON in one LO group and / or the number of subgroups SN per paging occasion through RRC configuration. If LON is not configured and LPON2 is configured, one LO group can contain ceil((SN*LPON2) / maxSN) LOs. If LPON2 is not configured and LON is configured, the number of subgroups SN per LPON2 paging occasions should satisfy SN*LPON2 is greater than maxSN and SN*LPON2 is less than the number of LOs, LPON2=floor((LON*maxSN) / SN). For example, if the number of POs associated to one LO group is 3 and / or the number of subgroups SN is 20, one LO group can contain 2 LOs. When the number of subgroups of 3 POs is 60, which is greater than 32 and less than 64, one LO group can be associated to 1.6 consecutive POs in one DRX cycle. Compared to one LO associated to one PO, for example, compared to 3 LO indications for 60 subgroups of 3 POs, this operation can use 2 LO indications for 60 subgroups of 3 POs, reducing the resource overhead of LO.

[0202] In another aspect, the wakeup signal monitoring condition and the condition for exiting the monitoring or fallback mechanism will be introduced.

[0203] In one embodiment, if SDT (Small Data transmission) or RACH procedure is ongoing in RRC inactive and / or idle state, the UE is not expected to monitor the wakeup signal or start the wakeup signal monitoring.

[0204] ​​In one embodiment, if SDT or RACH procedure is ongoing in RRC inactive and / or idle state, the UE does not expect to monitor the wake-up signal or does not start monitoring the wake-up signal, even if the wake-up signal monitoring condition is met. The wake-up signal monitoring condition includes that the reference signal received power (RSRP) of the serving cell measured by the MR based on SSB is greater than or equal to a threshold value 1 configured by SIB, and / or the reference signal received quality (RSRQ) of the serving cell measured by the MR based on SSB is greater than or equal to a threshold value 2 configured by SIB, and / or the RSRP of the serving cell measured by the LR based on LP-SS is greater than or equal to a threshold value 3 configured by SIB, and / or the RSRQ of the serving cell measured by the LR based on LP-SS is greater than or equal to a threshold value 4 configured by SIB, and / or the RSRP of the serving cell measured by the LR based on SSB is greater than or equal to a threshold value 5 configured by SIB, and / or the RSRQ of the serving cell measured by the LR based on SSB is greater than or equal to a threshold value 6 configured by SIB.

[0205] In one embodiment, if the UE expects to transmit a RACH related signal while monitoring the wake-up signal, the RACH related signal can be message 1 or message A, the UE does not expect to monitor the wake-up signal or stops monitoring the wake-up signal, and the UE expects to transmit the RACH related signal. The UE determines the resource for transmitting the RACH related signal is the nearest RO resource after the minimum wake-up latency is met. Optionally, the RACH is for establishing RRC connection.

[0206] In one optional solution, if the UE expects to transmit a RACH related signal and / or SDT while monitoring the wake-up signal, the UE does not expect to monitor the wake-up signal or stops monitoring the wake-up signal or suspends monitoring the wake-up signal, the UE expects to transmit the RACH related signal and / or SDT, and / or the UE does not expect to monitor the PO. Optionally, the RACH is not for establishing RRC connection or the RACH is for updating the parameter configuration information in SIB. Optionally, the UE determines the resource for transmitting the SDT is the nearest CG-PUSCH resource after the minimum wake-up latency is met, if the SDT is CG-SDT. Optionally, the UE determines the resource for transmitting the RACH related signal and / or the SDT resource is the nearest RO resource after the minimum wake-up latency is met, if the SDT is RA-SDT. Wherein, transmitting the SDT can also be referred to as performing the SDT. This operation takes into account that the RACH related signal and / or the SDT is more important, but since the UE does not receive the wake-up signal, the MR is woken up only to transmit the RACH related signal and / or the SDT and does not monitor the PO, which can save the power consumption of monitoring PDCCH. The UE behavior after the UE transmits the RACH related signal and / or the SDT can include one or more combinations of the following:

[0207] o UE expects to continue the wake-up signal monitoring;

[0208] o UE stops the wake-up signal monitoring;

[0209] o UE expects to start or continue the wake-up signal monitoring if the measurement of MR and / or LR satisfies the wake-up signal monitoring condition;

[0210] o UE expects to continue the wake-up signal monitoring after receiving the DL SDT if the SDT schedules a DL SDT;

[0211] o UE expects to start or continue the wake-up signal monitoring if the measurement of MR and / or LR satisfies the wake-up signal monitoring condition after receiving the DL SDT if the SDT schedules a DL SDT;

[0212] o UE starts a timer after receiving the DL SDT if the SDT schedules a DL SDT, UE expects to start or continue the wake-up signal monitoring if the timer expires without receiving the DL SDT, UE restarts or resets the timer if the DL SDT is received before the timer expires, UE expects to start or continue the wake-up signal monitoring when the timer expires. Optionally, UE expects to start or continue the wake-up signal monitoring when the timer expires if the measurement of MR and / or LR satisfies the wake-up signal monitoring condition. The length of the timer is predefined or preconfigured.

[0213] In an optional solution, UE is expected to monitor the wake-up signal if UE expects to transmit RACH related signal and / or SDT while monitoring the wake-up signal, UE delays the transmission of RACH related signal and / or SDT. Optionally, the RACH is not for establishing RRC connection or the RACH is for updating the parameter configuration information in SIB. UE monitors the PO after receiving the wake-up signal and after the wake-up delay is satisfied, UE transmits the RACH related signal and / or performs the SDT transmission. This operation can reduce the power consumption of UE when monitoring the wake-up signal.

[0214] In an embodiment, UE stops monitoring the wake-up signal if UE does not receive the wake-up signal in a predefined or preconfigured duration, UE monitors the PEI and / or monitors the PO, UE reports UE capability again, UE starts the wake-up signal monitoring if the measurement of MR and / or LR satisfies the wake-up signal monitoring condition. At this time, the network re-groups the UE based on the wake-up delay reported by UE again, UE determines the associated sub-group set and sub-group and / or sub-group sub-set according to the wake-up delay reported by UE again. This operation is suitable for the case that the network receives the UE capability error and the network considers that there is no UE in the sub-group where the UE is located.

[0215] In an optional solution, if the UE capability reported by the UE for the wake-up latency associated sub-group set index corresponding to the wake-up signal MO is not configured, the UE determines the sub-group set index of the largest wake-up latency associated wake-up signal sub-group set in the intersection of the one or more wake-up latency associated wake-up signal sub-group sets supported by the UE and the one or more wake-up latency associated wake-up signal sub-group sets configured by the network. This operation is applicable to the scenario that the network receives the UE capability error resulting in the inconsistent understanding of the wake-up signal sub-group set between the network and the UE.

[0216] In an optional solution, if the UE capability reported by the UE for the wake-up latency associated sub-group set index corresponding to the wake-up signal MO is not configured, and the intersection of the one or more wake-up latency associated wake-up signal sub-group sets supported by the UE and the one or more wake-up latency associated wake-up signal sub-group sets configured by the network is an empty set, the UE stops monitoring the wake-up signal, monitors the PEI and / or monitors the PO, and re-reports the UE capability. If the measurement of the MR and / or the LR satisfies the wake-up signal monitoring condition, the UE starts monitoring the wake-up signal. At this time, the network re-groups the wake-up latency based on the re-reported wake-up latency by the UE, and the UE determines the associated sub-group set and the sub-group and / or the sub-group sub-set according to the re-reported wake-up latency. This operation is applicable to the case that the UE cannot start the MR to monitor the PO within the configured wake-up latency.

[0217] In an embodiment, one LO is associated with one PO in a DRX cycle, for example, the period of the LO is the same as the period of the DRX. Considering that the paging message size of the UE can exceed the size of one data packet, the paging message can be transmitted in multiple data packets or data segments. When the UE receives the wake-up signal and / or the wake-up signal triggers the paging monitoring, the UE monitors the PO in the consecutive Y DRX cycles, does not expect to monitor the LO associated with the PO in the consecutive Y DRX cycles, and / or does not expect to start the monitoring of the wake-up signal. Optionally, the not expecting to start the monitoring of the wake-up signal can be not expecting to start the monitoring of the wake-up signal in the duration of the consecutive Y DRX cycles.

[0218] In yet another aspect, the UE behavior when only part of the wake-up signal monitoring conditions are satisfied, and / or the wake-up signal monitoring condition and the RRM measurement condition are different will be introduced.

[0219] In an embodiment, if the RSRP and / or the RSRQ of the serving cell measured by the MR is greater than the threshold value configured by the SIB respectively, and the RSRP and / or the RSRQ of the serving cell measured by the LR is less than the threshold value configured by the SIB respectively, the UE behavior can include one or more combinations of the following:

[0220] o UE does not expect to monitor for wake-up signal, UE still monitors for PEI and / or monitors for PO;

[0221] o UE can perform RRM measurement on LR based on LP-SS and / or SSB, UE turns on wake-up signal monitoring when the measurement of MR and / or LR meets the wake-up signal monitoring condition, and stops monitoring for PO before receiving the wake-up signal indication to wake up;

[0222] o MR can perform relaxed RRM measurement or no RRM measurement. This operation is to reduce the power consumption when both LR and MR are on;

[0223] o UE does not perform RRM measurement on LR based on LP-SS and / or SSB. UE turns on LR and / or performs RRM measurement on LR based on LP-SS and / or SSB after a pre-configured or pre-defined duration, UE turns on wake-up signal monitoring when the measurement of MR and / or LR meets the wake-up signal monitoring condition, and stops monitoring for PO before receiving the wake-up signal indication to wake up. Optionally, MR can perform relaxed RRM measurement during the duration. This operation is to reduce the measurement frequency of MR when the measurement of MR meets the wake-up signal monitoring condition, which can reduce the power consumption of UE.

[0224] In one embodiment, UE does not transmit periodic SRS signal and does not measure DL PRS when the condition of RRM measurement offloading is met or UE turns on wake-up signal monitoring. This operation is to reduce the extra power consumption of MR in deep sleep state when it is woken up to transmit periodic reference signal or perform DL PRS measurement.

[0225] In one embodiment, if the measurement of the MR and / or the LR satisfies the wake-up signal monitoring condition and the measurement of the MR and / or the LR satisfies the condition of RRM measurement offloading, the UE monitors the wake-up signal and performs the RRM measurement of the serving cell on the LR based on the LP-SS and / or the SSB, and the MR enters the super deep sleep state. If the measurement of the MR and / or the LR satisfies the wake-up signal monitoring condition, the measurement of the MR and / or the LR does not satisfy the condition of RRM measurement offloading, and if the measurement of the MR and / or the LR satisfies the RRM measurement condition for enabling MR relaxation, the UE monitors the wake-up signal, the UE performs the relaxed RRM measurement of the serving cell and / or the neighbor cell on the MR, and / or the UE performs the RRM measurement of the serving cell on the LR based on the LP-SS and / or the SSB, and / or the MR does not enter the super deep sleep state. Such operation can assist the RRM measurement of the MR with the RRM measurement performed on the LR, so that the MR can perform the relaxed RRM measurement, and the power consumption of the MR performing the RRM measurement can be further reduced. If the measurement of the MR and / or the LR satisfies the wake-up signal monitoring condition, the measurement of the MR and / or the LR does not satisfy the condition of RRM measurement offloading, and the measurement of the MR and / or the LR does not satisfy the RRM measurement condition for enabling MR relaxation, the UE monitors the LP-WUS, the UE does not perform the RRM measurement of the serving cell on the LR based on the LP-SS and / or the SSB, and / or the UE performs the RRM measurement of the serving cell and the neighbor cell on the MR based on the SSB, and the MR does not enter the super deep sleep state.
