Description

[0001] This application is a divisional application of Chinese invention patent application filed on May 8, 2025, with application number 202510592364.1 and title "User Equipment, Base Station and Method Thereof". Technical Field

[0002] This disclosure relates to the field of communications, and more specifically, to configuration and / or listening related to wake-up signals. Background Technology

[0003] To meet the increased demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or near-5G communication systems. Therefore, 5G or near-5G communication systems are also referred to as "super 4G networks" or "post-LTE systems".

[0004] 5G communication systems are implemented in higher frequency (millimeter wave, mmWave) bands, such as the 60GHz band, to achieve higher data rates. To reduce radio wave propagation loss and increase transmission distance, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive MIMO technologies are discussed in 5G communication systems.

[0005] In addition, in 5G communication systems, development is underway to improve the system network based on advanced small cells, cloud radio access networks (RAN), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, cooperative multipoint (CoMP), receiver interference cancellation, and other technologies.

[0006] In 5G systems, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) have been developed as advanced coding and modulation (ACM), as well as filter bank multicarrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA) as advanced access technologies. Summary of the Invention

[0007] According to embodiments of this disclosure, a method executed by a user equipment (UE) in a communication system is provided, comprising:

[0008] Receive configuration information related to a wake-up signal, the configuration information including first configuration information related to the timing of the wake-up signal and second configuration information related to the listening timing (MO) for the wake-up signal, the wake-up signal timing including multiple MOs;

[0009] Based on the wake-up latency-related information supported by the UE, determine the set of wake-up signal subgroups associated with the UE;

[0010] Based on the determined set of wake-up signal subgroups and the second configuration information, the time-domain location of the MO used to listen for wake-up signals is determined;

[0011] Based on the determined time-domain location of the MO, listen for the wake-up signal.

[0012] In one implementation, determining the set of wake-up signal subgroups associated with the UE based on wake-up latency-related information supported by the UE includes:

[0013] The wake-up signal subgroup set index associated with the UE is determined based on the first correspondence between the wake-up signal subgroup set index and the wake-up delay.

[0014] In one implementation, the wake-up delay in the first correspondence is associated with different sets of wake-up signal subgroups in descending or ascending order.

[0015] In one implementation, if the UE does not report the wake-up delay, the set of wake-up signal subgroups associated with the UE is the set of wake-up signal subgroups corresponding to the maximum wake-up delay in the intersection of the wake-up delay related to the wake-up signal timing configured by the first configuration information and / or the wake-up delay related to the MO configured by the second configuration information, determined based on the first correspondence, and the wake-up delay supported by the UE.

[0016] In one implementation, the method further includes: reporting the wake-up latency supported by the UE through capability information.

[0017] Wherein, if the wake-up delay reported by the UE is different from both the wake-up delay related to the wake-up signal timing configured in the first configuration information and / or the wake-up delay related to the MO configured in the second configuration information, then the UE determines the set of wake-up signal subgroups corresponding to the maximum wake-up delay in the intersection of the wake-up delay related to the wake-up signal timing configured in the first configuration information and / or the wake-up delay related to the MO configured in the second configuration information, determined based on the first correspondence relationship, and the wake-up delays supported by the UE, as the set of wake-up signal subgroups associated with the UE; or

[0018] If the wake-up delay reported by the UE is the same as at least one of the wake-up delay related to the wake-up signal timing configured in the first configuration information and / or the wake-up delay related to the MO configured in the second configuration information, then the set of wake-up signal subgroups associated with the UE is the set of wake-up signal subgroups corresponding to the wake-up delay reported by the UE, determined based on the first correspondence.

[0019] In one implementation, if the wake-up delay related to the wake-up signal timing configured in the first configuration information and / or the wake-up delay related to the MO configured in the second configuration information do not include the wake-up delay supported by the UE, then the UE does not listen to the wake-up signal.

[0020] In one implementation, based on the determined set of wake-up signal subgroups and the second configuration information, the temporal location of the MO used to listen for wake-up signals is determined, including:

[0021] Based on the second correspondence between the wake-up signal subgroup set index and the MO set, the MO set corresponding to the wake-up signal subgroup set is determined;

[0022] Based on the second configuration information, the temporal location of the MO set is determined;

[0023] Each MO set includes K consecutive K N MOs, where N is the number of beams transmitting wake-up signals, and K is the number of wake-up signals transmitted on each beam used for beam scanning, corresponding to each set of wake-up signal subgroups.

[0024] The i-th MO set includes the i-th group of K consecutive MOs in each beam direction used for beam scanning, where i takes values ​​from 1 to X, and X is the number of wake-up signal subgroups.

[0025] In one implementation, each set of wake-up signal subgroups includes M sets of wake-up signal subgroups.

[0026] Specifically, based on the determined set of wake-up signal subgroups and the second configuration information, the time-domain location of the MO used for listening to wake-up signals is determined, including:

[0027] Based on the third correspondence between the wake-up signal subgroup subset index and the MO set, the MO set corresponding to the wake-up signal subgroup set is determined;

[0028] Based on the second configuration information, the temporal location of the MO set is determined;

[0029] Each MO set includes K consecutive K N MOs, where N is the number of beams transmitting wake-up signals, and K is the number of wake-up signals transmitted on each beam corresponding to each subset of wake-up signal subgroups, or

[0030] The i-th MO set includes the i-th consecutive MO in each beam direction, where i takes values ​​from 1 to M. X, where X is the number of wake-up signal subgroups.

[0031] In one implementation, the method further includes: determining, based on the UE's identification information, a subset of subgroups associated with the UE within the determined set of wake-up signal subgroups.

[0032] Based on the UE's identification information and the number of information bits corresponding to the wake-up signal, the subgroup index associated with the UE in the determined subgroup subset is determined.

[0033] Listen for wake-up signals based on the subgroup index.

[0034] In one implementation, the method further includes: if the detected wake-up signal includes information related to a subgroup index associated with the UE, then the UE listens for a paging message.

[0035] If the detected wake-up signal does not include information related to the subgroup index associated with the UE, the UE listens for the next wake-up signal timing based on the first configuration information.

[0036] In one implementation, the MO sets corresponding to adjacent wake-up signal subgroups have the same interval, which is the same as the interval between adjacent MOs in each MO set, or

[0037] The MO sets corresponding to adjacent wake-up signal subgroups have different intervals, and the intervals are not the same as the intervals between adjacent MOs in each MO set.

[0038] In one implementation, the method further includes:

[0039] In the first case, stop listening or do not expect to listen for the wake-up signal.

[0040] The first case includes at least one of the following:

[0041] In the RRC inactive state or idle state, the UE performs small data transmission SDT or transmits random access channel RACH;

[0042] In the RRC inactive state or idle state, the UE is performing small data transmission SDT or transmitting random access channel RACH, and the wake-up signal listening condition is met;

[0043] The UE expects to send RACH-related signals;

[0044] The UE expects to perform SDT.

[0045] In one implementation, the method further includes at least one of the following:

[0046] Send RACH-related signals;

[0047] Execute SDT;

[0048] We do not expect to listen to the PO.

[0049] In one implementation, the method further includes performing at least one of the following after sending the RACH-related signal and / or performing SDT:

[0050] We expect to continue listening for wake-up signals;

[0051] Stop listening to PO;

[0052] If the MR and / or LR measurements of the UE meet the wake-up signal listening conditions, the UE wishes to enable or continue wake-up signal listening;

[0053] If the SDT schedules a DL SDT, then after receiving the DL SDT, the UE expects to continue listening for wake-up signals.

[0054] If the SDT schedules the DL SDT, then after receiving the DL SDT, if the MR and / or LR measurements of the UE meet the wake-up signal listening conditions, the UE expects to enable or continue wake-up signal listening.

[0055] If the SDT schedules a DL SDT, a timer is started after the DL SDT is received. If the DL SDT is not received before the timer expires, the UE expects to enable or continue listening for wake-up signals. If the DL SDT is received before the timer expires, the UE resets the timer.

[0056] In one implementation, if the UE expects to send a RACH-related signal while listening for a wake-up signal, then the UE listens for the wake-up signal, wherein the RACH-related signal does not include information related to an RRC connection request, or the RACH-related signal includes information related to an RRC recovery request; and / or

[0057] If the UE expects to perform SDT while listening for a wake-up signal, then the UE is expected to listen for a wake-up signal.

[0058] In one implementation, if the UE does not detect a wake-up signal within a first duration, the UE stops detecting the wake-up signal and reports the wake-up latency supported by the UE.

[0059] In one implementation, if the wake-up delay reported by the UE is different from any of the wake-up delays corresponding to the configured wake-up signal subgroup set, the UE stops listening to the wake-up signal and re-reports the wake-up delay supported by the UE.

[0062] The UE does not expect to listen to the wake-up signal; the UE listens to PEI and / or listens to PO.

[0063] The UE performs RRM measurements of the serving cell on the LR based on LP-SS and / or SSB until the measurements of MR and / or LR meet the wake-up signal listening conditions. The UE then starts listening to the wake-up signal and stops listening to the PO before receiving the wake-up signal.

[0064] MR may perform relaxed RRM measurements or not perform RRM measurements;

[0065] The UE does not perform RRM measurements of the serving cell on the LR based on LP-SS and / or SSB;

[0066] After a pre-configured or pre-defined second duration, the UE enables LR and / or performs RRM measurements of the serving cell on LR based on LP-SS and / or SSB until the measurements of MR and / or LR meet the wake-up signal listening conditions. The UE then enables wake-up signal listening and stops listening to PO before receiving a wake-up signal.

[0067] In one implementation, during the second duration, MR performs a relaxed RRM measurement.

[0070] If the measurements of MR and / or LR satisfy the wake-up signal listening condition and the measurements of MR and / or LR satisfy the RRM measurement offload condition, then the UE listens for the wake-up signal and performs the serving cell's RRM measurement on the LR based on LP-SS and / or SSB, and the MR enters a deep sleep state.

[0071] If the measurements of MR and / or LR meet the wake-up signal listening conditions, and the measurements of MR and / or LR do not meet the RRM measurement offload conditions, and if the measurements of MR and / or LR meet the conditions for enabling MR relaxation of RRM measurement, then the UE listens for the wake-up signal, the UE performs relaxed RRM measurement of the serving cell and / or neighboring cell on the MR, and / or the UE performs RRM measurement of the serving cell on the LR based on LP-SS and / or SSB, and / or the MR does not enter a deep sleep state.

This description includes various specific details to aid understanding but should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of this disclosure. Furthermore, for clarity and brevity, descriptions of well-known functions and structures may be omitted.

[0115] The terms and wording used in the following description and claims are not limited to their dictionary meanings, but are merely used by the inventors to enable a clear and consistent understanding of this disclosure. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of this disclosure is for illustrative purposes only and not for limiting the purpose of this disclosure as defined in the appended claims and their equivalents.

[0116] It should be understood that the singular forms of “one,” “an,” and “the” include plural references unless the context clearly indicates otherwise. Thus, for example, the reference to “component surface” includes one or more such surfaces.

[0117] The terms “comprising” or “may include” refer to the presence of a corresponding disclosed function, operation, or component that may be used in the various embodiments of this disclosure, rather than limiting the presence of one or more additional functions, operations, or features. Furthermore, the terms “comprising” or “having” may be interpreted as indicating certain characteristics, numbers, steps, operations, constituent elements, components, or combinations thereof, but should not be construed as excluding the possibility of the presence of one or more other characteristics, numbers, steps, operations, constituent elements, components, or combinations thereof.

[0118] The term "or" as used in the various embodiments of this disclosure includes any of the listed terms and all combinations thereof. For example, "A or B" may include A, may include B, or may include both A and B.

[0119] Unless otherwise defined, all terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of those skilled in the art as described herein. Common terms as defined in dictionaries are to be interpreted as having a meaning consistent with the context in the relevant technical field and should not be interpreted ideally or overly formally unless expressly defined in this disclosure.

[0120] The various embodiments of this disclosure can be applied to various communication systems, such as: Global System for Mobile Communications (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, General Packet Radio Service (GPRS), Long Term Evolution (LTE) systems, Frequency Division Duplex (FDD) systems, Time Division Duplex (TDD) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, 5th Generation (5G) systems, or New Radio (NR), etc. Furthermore, the various embodiments of this disclosure can be applied to future-oriented communication technologies.

[0121] Figure 1 An example wireless network 100 according to various embodiments of the present disclosure is shown. Figure 1 The embodiment of the wireless network 100 shown is for illustrative purposes only. Other embodiments of the wireless network 100 can be used without departing from the scope of this disclosure.

[0122] 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 proprietary IP network, or other data network.

[0123] 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. Furthermore, depending on the network type, other well-known terms such as "mobile station", "user 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 remote wireless devices that wirelessly access the gNB, whether the UE is a mobile device (such as a mobile phone or smartphone) or a fixed device as commonly understood (such as a desktop computer or vending machine).

[0124] gNB 102 provides wireless broadband access to network 130 to multiple first user equipments (UEs) within its coverage area 120. The multiple first 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); and UE 116, which may be a mobile device (M), such as a cellular phone, wireless laptop computer, wireless PDA, etc. gNB 103 provides wireless broadband access to network 130 to multiple second UEs within its coverage area 125. The multiple second UEs include UE 115 and UE 116. In some embodiments, one or more of gNBs 101-103 are capable of communicating with each other and with UEs 111-116 using 5G, LTE, LTE-A, WiMAX, or other advanced wireless communication technologies.

[0125] The dashed lines indicate the approximate extent of coverage areas 120 and 125, which are shown as approximately circular for illustrative and explanatory purposes only. It should be clearly understood that coverage areas associated with the gNB, 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.

[0126] 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 this disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook design and architecture for systems having 2D antenna arrays.

[0127] although Figure 1 An example of a wireless network 100 is shown, but it is possible to... Figure 1 Various modifications can be made. For example, wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Furthermore, 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 external telephone networks or other types of data networks.

[0128] Figure 2a and Figure 2b Example wireless transmit and receive paths according to this disclosure are shown. In the following description, transmit path 200 can be described as being implemented in a gNB (such as gNB 102), while 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 having a 2D antenna array as described in embodiments of this disclosure.

[0129] 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, 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, 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.

[0130] In transmit path 200, 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 modulated symbols. Serial-to-parallel (S-to-P) block 210 converts (e.g., demultiplexes) the serial modulated symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points used in gNB 102 and UE 116. N-point IFFT block 215 performs IFFT operations on the N parallel symbol streams to generate a time-domain output signal. Parallel-to-serial block 220 converts (e.g., multiplexes) the parallel time-domain output symbols from N-point IFFT block 215 to generate a serial time-domain signal. Cyclic prefix addition block 225 inserts a cyclic prefix into the time-domain signal. Upconverter 230 modulates (e.g., upconverts) the output of the added cyclic prefix block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at the baseband before being converted to the RF frequency.

[0131] The RF signal transmitted from gNB 102 reaches UE 116 after passing through the wireless channel, and UE 116 performs the opposite operation to that at gNB 102. Downconverter 255 downconverts the received signal to the baseband frequency, and cyclic prefix removal 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.

[0132] Each of gNBs 101-103 can implement a transmission path 200 similar to that used for transmission to UEs 111-116 in the downlink, and a reception path 250 similar to that used for reception from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 can implement a transmission path 200 for transmission to gNBs 101-103 in the uplink, and a reception path 250 for reception from gNBs 101-103 in the downlink.

[0133] Figure 2a and Figure 2b Each of the components can be implemented using hardware alone, or using a combination of hardware and software / firmware. As a specific example, Figure 2a and Figure 2bAt least some of the components can be implemented in software, while others can be implemented in configurable hardware or a combination of software and configurable hardware. For example, FFT block 270 and IFFT block 215 can be implemented as configurable software algorithms, wherein the value of the number of points N can be modified according to the implementation method.

[0134] Furthermore, although the description uses FFT and IFFT, this is merely illustrative and should not be construed as limiting the scope of this disclosure. Other types of transforms, such as the Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions, can be used. 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 that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0135] although Figure 2a and Figure 2b An example of a wireless transmit and receive path is shown, but it is possible to modify it further. Figure 2a and Figure 2b Make various changes. For example, Figure 2a and Figure 2b The various components can be combined, further subdivided, or omitted, and additional components can be added as needed. Furthermore, Figure 2a and Figure 2b This is intended to illustrate examples of the types of send 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.

[0136] Figure 3a Example UE 116 according to this disclosure is shown. Figure 3a The embodiment of UE 116 shown is for illustrative purposes only, and Figure 1 UEs 111-115 can have the same or similar configurations. However, UEs have a wide variety of configurations, and Figure 3a This disclosure is not intended to limit the scope of any particular implementation of the UE.

[0137] UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a transmit (TX) processing circuitry 303, a microphone 304, and a receive (RX) processing circuitry 305. UE 116 also includes a speaker 306, a controller / processor 307, an input / output (I / O) interface 308, multiple input devices 309, a display 310, and a memory 311. The memory 311 includes an operating system (OS) 312 and one or more applications 313.

[0138] RF transceiver 302 receives incoming RF signals transmitted by a gNB of wireless network 100 from antenna 301. RF transceiver 302 down-converts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to RX processing circuitry 305, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 305 sends the processed baseband signal to speaker 306 (e.g., for voice data) or to controller / processor 307 (e.g., for web browsing data) for further processing.

[0139] TX processing circuitry 303 receives analog or digital voice data from microphone 304, or other outgoing baseband data (such as network data, email, or interactive video game data) from controller / processor 307. TX processing circuitry 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. RF transceiver 302 receives the processed baseband or IF signals from TX processing circuitry 303 and up-converts the baseband or IF signals into RF signals transmitted via antenna 301.

[0140] The controller / processor 307 may include one or more processors or other processing devices and execute an OS 312 stored in memory 311 to control the overall operation of the UE 116. For example, the controller / processor 307 may control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceiver 302, the RX processing circuit 305, and the TX processing circuit 303 according to known principles. In some embodiments, the controller / processor 307 includes at least one microprocessor or microcontroller.

[0141] The controller / processor 307 is also capable of executing other processes and programs residing in the memory 311, such as operations for channel quality measurement and reporting for a system having a 2D antenna array as described in the embodiments of this disclosure. The controller / processor 307 is capable of moving data into or out of the memory 311 as needed for the execution of the process. In some embodiments, the controller / processor 307 is configured to execute an application 313 based on the OS 312 or in response to signals received from a gNB or operator. The controller / processor 307 is also coupled to an I / O interface IF 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.

[0142] The controller / processor 307 is also coupled to input devices(s) 309 and a display 310. An operator of the UE 116 can use the input devices(s) 309 to input data into the UE 116. The display 310 may be a liquid crystal display (LCD) or another display capable of displaying text and / or at least limited graphics (such as from a website). Memory 311 is coupled to the controller / processor 307. A portion of memory 311 may include random access memory (RAM), while another portion of memory 311 may include flash memory or other read-only memory (ROM).

[0143] 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 can be combined, further subdivided, or omitted, and additional components can be added as needed. As a specific 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). Furthermore, although... Figure 3a The UE116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or fixed devices.

[0144] Figure 3b An example gNB 102 according to this disclosure is shown. Figure 3b The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 Other gNBs can have the same or similar configurations. However, gNBs have a wide variety of configurations, and Figure 3b The scope of this 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 structures as gNB 102.

[0145] like Figure 3b As shown, 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] although Figure 3b An example of gNB 102 is shown, but it is possible to compare it with other models. Figure 3b Various modifications can be made. For example, gNB102 can include any number of... Figure 3a Each component shown. As a specific example, the access point can include multiple 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, 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).

[0154] The time unit (also called a time cell) in this application can be: an OFDM symbol, an OFDM symbol group (composed of multiple OFDM symbols), a time slot, a time slot group (composed of multiple time slots), a subframe, a subframe group (composed of multiple subframes), a system frame, or a 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 an OOK chip.

[0155] The frequency domain unit (also called frequency unit) in this application can be: a subcarrier, a subcarrier group (composed of multiple subcarriers), a resource block (RB), also called a physical resource block (PRB), a resource block group (composed of multiple RBs), a bandwidth part (BWP), a bandwidth part group (composed of multiple BWPs), a bandwidth / carrier, a bandwidth 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.

[0156] Exemplary embodiments of this disclosure are further described below with reference to the accompanying drawings.

[0157] The text and accompanying drawings are provided by way of example only to aid the reader in understanding this disclosure. They are not intended and should not be construed as limiting the scope of this 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 content disclosed herein, that changes may be made to the illustrated embodiments and examples without departing from the scope of this disclosure.

[0158] The transmission links of a 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 UE to UE.

[0159] In wireless communication systems, such as current ones, to reduce terminal-side energy consumption, a Discontinuous Reception (DRX) mechanism is introduced. In the RRC inactive and / or idle state, the DRX period equals the paging period. The UE listens for a paging occasion (PO) within each DRX period, and spends most of the time in sleep mode and does not need to listen to the PDCCH during the majority of each DRX period, except for the paging occasion. When the UE hears a P-RNTI-scrambled PDCCH in the corresponding PO, it continues to read the identifier of the paging terminal in the paging message. If the read terminal identifier matches its own identifier, the UE further reads the paging message; otherwise, it discards the paging message. To further reduce UE energy consumption during this process, 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 will monitor the PEI occasion once in each DRX cycle. If the UE detects the PEI indication and the PEI indicates that the UE should listen to the associated PO, the UE should wake up and listen to the PO at the associated PO; otherwise, the UE does not need to wake up and listen to the PO.

[0160] In some use cases with more stringent requirements for low UE power consumption (such as IoT devices and / or wearable devices), wireless communication systems can use a low-power wake-up signal (e.g., the new Low Power Wake Up Signal, LPWUS) to wake up the UE in order to further extend UE battery life. Therefore, improvements are needed in the configuration and / or listening procedures for wake-up signals (e.g., LPWUS).

[0161] In the following description, for ease of description, LPWUS is used as an example of a wake-up signal. It should be understood that this is merely exemplary, and the wake-up signal involved in the embodiments of this disclosure may have other names, or the wake-up signal may include other types of wake-up signals.

[0162] Exemplarily, this invention will describe a method and apparatus for configuring and monitoring low-power wake-up signals. In one embodiment of this invention, the application of the method according to this disclosure in at least one of the following aspects will be described: a method for determining a set of subgroups, a time-domain location of LPWUS monitoring, a method for determining a subgroup index in an associated set of subgroups, LPWUS monitoring enable and exit conditions, and UE behavior when the enable conditions for RRM measurement offloading (e.g., offloading to a wake-up signal receiving module) and the LPWUS monitoring enable conditions differ. As previously described, in embodiments of this disclosure, wake-up signals are used for exemplary purposes, wherein wake-up signals include, but are not limited to, LPWUS signals, and the described methods can also be used for configuring and transmitting other signals.

[0163] The UE's receiver comprises two modules: a Main Radio (MR) module for receiving regular signals / channels transmitted by the base station, and a Lower Power Wake Up Receiver (LPWUR) module for receiving wake-up signals transmitted by the base station. A dedicated module is used to receive wake-up signals because LPWUR is based on an existing NR system's Orthogonal Frequency Division Multiplexing (OFDM) waveform, further modulated using Amplitude Shift Keying (ASK). LPWUR can listen for wake-up signals at extremely low power. Once the UE detects the wake-up signal, LPWUR can trigger the MR to transition from a dormant state to an active state, listening for PEI and / or PO. Optionally, On-Off Keying (OOK) modulation is a special case of ASK modulation. LPWUR includes two different types of receivers: OOK-based receivers and OFDM-based receivers. OOK-based receivers perform synchronization and RRM measurements based on LP-SS, while OFDM-based receivers perform synchronization and RRM measurements based on SSB.

[0164] Figure 4 An example flowchart of a method performed by a user equipment (UE) according to an embodiment of the present disclosure is shown. Figure 4 The method can determine the wake-up signal grouping and listening resources (e.g., the wake-up signal listening time (MO)) based on the UE's capabilities.

[0165] like Figure 4 As shown, the method includes steps 401-404:

[0166] Step 401: Receive configuration information related to a wake-up signal used to wake up the UE, wherein the configuration information includes configuration information for the timing of receiving a wake-up signal and the timing of listening to the wake-up signal;

[0167] Step 402: Determine the index of the wake-up signal subgroup set associated with the UE based on the UE capabilities related to the wake-up latency supported by the UE;

[0168] Step 403: Based on the determined subgroup set index, determine the LP-WUS subgroup set index and / or subgroup index of the UE in the subgroup set, and determine the time domain location of LP-WUS monitoring according to the association between the subgroup index and MO resources and the configuration information.

[0169] Step 404: Based on the determined time-domain location of the wake-up signal listening timing, listen for the wake-up signal. If the codeword indicated by the wake-up signal contains the UE subgroup index, the UE is woken up to listen for paging messages. If the codeword indicated by the wake-up signal does not contain the UE subgroup index, the UE listens for LP-WUS according to the configured LP-WUS period. Optionally, the method may further include step 401-1: The UE reports the supported wake-up latency through UE capabilities.

[0170] It should be understood that, for ease of description, the term "wake-up signal subgroup set" is used in this disclosure, but this name is merely exemplary and other names may be used, such as wake-up signal group set, LP-WUS group set, LP-WUS subgroup set, LP-WUS set, wake-up signal set, etc.

[0171] The technical solutions of this disclosure will now be described in more detail with reference to exemplary embodiments.

[0172] In one aspect, a method for determining the LPWUS subgroup set and the temporal location of the listener will be introduced.

[0173] In one embodiment, the UE reports the supported wake-up latency through its UE capabilities. Optionally, the wake-up latency can be one or more wake-up latencies selected from X candidate values. The wake-up latency is the minimum time interval from receiving the wake-up signal to starting MR listening to PDCCH. X can be pre-configured or pre-defined, and X is an integer greater than 1. For example, X can be equal to 2. This operation is to support two wake-up latencies for waking up the UE from ultra-deep sleep and deep sleep states to listen to PDCCH. Optionally, the two wake-up latencies can be 400ms and 20ms, respectively. As another example, X can be equal to 3. This operation is to support two UE capabilities for waking up the UE from ultra-deep sleep and listening to PDCCH, and different wake-up latencies for waking up the UE from ultra-deep sleep and deep sleep states to listen to PDCCH. Optionally, the three wake-up latencies can be 800ms, 400ms, and 20ms, respectively.

[0174] In one embodiment, a wake-up signal timing (e.g., LPWUS Occasion, LO) can be associated with one or more paging timings (PO). All UEs corresponding to the one or more POs associated with the LO constitute a UE group. To reduce the paging latency of UEs in a deep sleep state (e.g., wake-up latency of 20ms) within the UE group, the UEs within the UE group can be further subgrouped, with UEs having the same wake-up latency placed into the same subgroup set. The total number of wake-up signal subgroup sets can be equal to the number of candidate values ​​for the wake-up latency.

[0175] In one embodiment, the UE obtains configuration information of the Locator (LO) and configuration information of the Monitoring Occasion (MO) through a System Information Block (SIB) message. Each LO may contain multiple MOs, and the UE can select the appropriate MO from the K. N consecutive MOs or Ks N non-contiguous MO (Multi-Organization) internal listening wake-up signals, where K is the number of MOs transmitting the same and / or different wake-up signal information bits in the same beam direction, and N is the number of beams of wake-up signals establishing a quasi-co-location (QCL) relationship with the SSB (Security Service Bus) or LP-SS (Limited-Location Service Bus). K and N are predefined or pre-configured values, and are integers greater than or equal to 1. The LO (Location Entity) configuration information includes at least one of the following parameters: the minimum time interval from the end or start position of the LO to the start point of one or more POs associated with the LO, where the start point of the multiple POs is the start point of the first PO among the multiple POs; the duration of the LO, optionally, the duration can be the maximum duration of the LO. If the UE receives a wake-up signal after the maximum duration of the LO, the UE does not expect to listen to the one or more associated POs. The configuration information of the wake-up signal MO includes at least one of the following parameters: the interval between the first wake-up signal MO and the start of LO, the interval between two adjacent wake-up signals MO, the duration of the wake-up signal MO, the interval between the first wake-up signal MO and the start or end position of LO in each wake-up signal subgroup set, and the number or length of MOs associated with each wake-up signal subgroup set.

[0176] The configuration information of the LO also includes at least one of the following parameters:

[0177] A first offset from the starting position of the LO to the starting point of the radio frame containing one or more POs associated with the LO, wherein the starting point of the radio frame containing the plurality of POs is the starting point of the radio frame containing the first PO among the plurality of POs. The first offset is the number of radio frames;

[0178] In one embodiment, if the UE reports a supported wake-up delay, the UE determines the index of the associated wake-up signal subgroup set based on the reported wake-up delay. Optionally, based on a predefined or preconfigured correspondence between wake-up delays and wake-up signal subgroup set indices, for example, according to the definitions in Table 1, the UE can determine the index of the wake-up signal subgroup set based on the UE capability of a reported wake-up delay. The method by which the UE determines the associated wake-up signal subgroup set based on the predefined or preconfigured correspondence between wake-up delays and wake-up signal subgroup set indices may also include a combination of one or more of the following:

[0179] If the UE does not report a supported wake-up delay, the UE determines the index of the associated wake-up signal subgroup set based on the maximum value among the more than one supported wake-up delay candidate values.

[0180] If the UE does not report the supported wake-up latency, and the network does not configure a set of wake-up signal subgroups associated with one or more UE capabilities supported by the UE, the UE will not listen for wake-up signals. If the UE does not receive a wake-up signal within a predefined or preconfigured duration, the UE will wake up and listen for PEI or periodically listen for PO, and re-report the UE capabilities.

[0181] If the UE does not report the supported wake-up latency, and the network configures a set of wake-up signal subgroups associated with one or more UE capabilities supported by the UE, the UE determines the subgroup set index as the index of the largest wake-up latency associated wake-up signal subgroup set in the intersection of the set of one or more wake-up latency associated with the UE supported and the set of one or more wake-up latency associated with the network configured.

[0182] If the UE reports a supported wake-up delay, but the network does not configure a set of wake-up signal subgroups associated with the UE's reported UE capability, the UE determines the subgroup set index as the index of the largest wake-up delay associated wake-up signal subgroup set in the intersection of one or more wake-up delay associated wake-up signal subgroup sets supported by the UE and one or more wake-up delay associated wake-up signal subgroup sets configured by the network.

[0183] In one embodiment, the UE determines the start position of the LO by the start point of the first paging frame of the first PO among one or more POs associated with the LO and the first offset, determines the end position of the wake-up signal LO or the wake-up signal MO that is expected to be listened to by the start position of the PO associated with the UE and a wake-up delay reported by the UE, and / or the UE does not expect to listen to the wake-up signal MO after the time unit determined by the start position of the PO associated with the UE and the minimum wake-up delay reported by the UE, and / or the UE listens to the PO.

[0184] Table 1 shows the correspondence between wake-up delay and the index of the wake-up signal subgroup set.

[0185] In one embodiment, more than one set of wake-up signal subgroups can be associated with a single LO. The UE can establish or obtain the association between the set of wake-up signal subgroups and the wake-up signal transmission resources to determine the location of the time-domain resources for listening to wake-up signals. For example, based on the order of wake-up delays corresponding to the set of wake-up signal subgroups, the association includes the first group of K consecutive K subgroups in the LO. N wake-up signals MO are associated with wake-up signal subgroup set 1, the second group is continuous K N wake-up signals MO are associated with a set of 2 wake-up signal subgroups, and so on, such as Figure 5 As shown. This approach associates users with longer wake-up latency with wake-up signals (MOs) preceding the LO, and users with shorter wake-up latency with MOs within the LO that are closer to the associated PO, thus reducing paging latency for users with shorter wake-up latency. For example, assuming the wake-up signal subgroup set is 2, the network can configure the time interval from the end position of the LO to the start position of one or more POs as max(T1-T2,T3) through the algorithm. Here, T1 represents the first time interval from the end position of the wake-up signal MO corresponding to the wake-up signal subgroup set 1 associated with a longer wake-up latency to the start position of one or more POs, and the first time interval includes or is equal to the wake-up latency associated with the wake-up signal subgroup set 1; T2 represents the second time interval from the end position of the wake-up signal MO corresponding to the wake-up signal subgroup set 1 associated with a longer wake-up latency to the end position of the LO; the second time interval includes or is equal to the duration of multiple consecutive MOs associated with the wake-up signal subgroup set 2 associated with a shorter wake-up latency; and T3 represents the wake-up latency associated with the wake-up signal subgroup set 2 associated with a shorter wake-up latency.

[0186] In another embodiment, more than one set of wake-up signal subgroups can be associated with different LOs. For example, one set of wake-up signal subgroups corresponds to one LO. The UE can establish or obtain the association between the set of wake-up signal subgroups and the wake-up signal transmission resources (such as LOs) to determine the temporal resource location for listening to the wake-up signal. For example, based on the order of wake-up latency corresponding to the set of wake-up signal subgroups, the association includes the first LO being associated with wake-up signal subgroup 1, the second LO being associated with wake-up signal subgroup 2, and so on. This approach associates users with longer wake-up latency with earlier LOs and users with shorter wake-up latency with LOs closer to the starting position of the PO, reducing the paging latency for users with shorter 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 of an excessive number of associated subgroups within a single wake-up signal causing insufficient information bits to carry 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 the wake-up signal on associated resources. If the subgroup index indicated by the wake-up signal matches 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 differs from the UE's subgroup index, the UE continues to listen for the wake-up signal 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 consecutive K in the LO. N wake-up signals MO are associated with wake-up signal subgroup 1 in wake-up signal subgroup 1, and the second group is K consecutive N wake-up signals MO are associated with wake-up signal subgroup 2 in wake-up signal subgroup 1, and so on; wake-up signal subgroup 1 in LO is associated with M K The first group of consecutive K after N MOs N wake-up signals MO are associated with wake-up signal subgroup 1 in wake-up signal subgroup 2, and wake-up signal subgroup 1 is associated with M. K The second group of consecutive K after N MOs N wake-up signals MO are associated with wake-up signal subset 2 in wake-up signal subset set 2, and so on. Here, M is the number of wake-up signal subsets within a single wake-up signal subset set. Alternatively, the association between wake-up signal subsets and MO can be similar to... Figure 6 The method is shown. For example, in each of the N beam directions in the LO, the first group of K consecutive MOs is associated with the first group of wake-up signal subgroups, the second group of K consecutive MOs is associated with the second group of wake-up signal subgroups, and so on; in each of the N beam directions in the LO, the wake-up signal subgroup set 1 is associated with M The first set of K consecutive wake-up signals after K MOs are associated with the first set of wake-up signal subgroups in set 2, and the wake-up signal subgroup set 1 is associated with M. The second set of K consecutive wake-up signals MO after K MOs are associated with the second set of wake-up signal subsets in the set 2, and so on.

[0189] In one embodiment, the MOs corresponding to two adjacent sets of wake-up signal subgroups within a LO are consecutive. For example, within a LO, the interval between any two adjacent wake-up signal MOs is equal. The UE can determine the starting position of the first MO in the LO based on the configured LO start point and the interval between the first wake-up signal MO and the LO start point. It can also determine the temporal position of subsequent MOs based on the starting position of the first MO, the duration of the wake-up signal MO, and the interval between two adjacent wake-up signal MOs. This operation can improve resource utilization efficiency while reducing user paging latency to some extent.

[0190] In one implementation, the starting point of the LO is the starting point of the radio frame in which the LO is located. The UE determines the starting position of the time slot in which the first MO is located based on the configured starting point of the LO and the interval between the configured first wake-up signal MO and the LO starting point, wherein the interval between the configured first wake-up signal MO and the LO starting point is the number of time slots. In a LO, the starting position of the subsequent or next wake-up signal MO is determined based on the starting or ending position of the previous wake-up signal MO and the interval between a configured adjacent wake-up signal MO. Optionally, the interval between a configured adjacent wake-up signal MO is the number of time slots or OFDM symbols, the starting position of a wake-up signal MO is the starting position of a time slot or OFDM symbol, and the duration of a configured wake-up signal MO is the number of time slots or OFDM symbols. The UE can determine the valid / available wake-up signal OFDM symbol based on other configured signals and / or channels, wherein the other signals and / or channels include, but are not limited to, SSB, CORESET / Type-0 CSS, TDD DL / UL configuration, and cell-specific reference signal CRS, and the other signals and / or channels are configured by SIB1. For example, in each wake-up signal (MO), in the frequency domain resources, if the physical resource block containing the wake-up signal or the physical resource block used for wake-up signal transmission overlaps or collides with other signals and / or channels (in the frequency domain resources), the OFDM symbol corresponding to the physical resource block containing the wake-up signal or the physical resource block used for wake-up signal transmission that overlaps or collides cannot be used for wake-up signal transmission or is not a valid / usable wake-up signal resource, wherein the physical resource block contains a guard interval. In the frequency domain resources, if the physical resource block containing the wake-up signal or the physical resource block used for wake-up signal transmission does not overlap or collide with other signals and / or channels (in the frequency domain resources), and in the time domain resources, if the OFDM symbol containing the wake-up signal or the OFDM symbol used for wake-up signal transmission does not overlap or collide with other signals and / or channels (in the time domain resources), the UE determines that the OFDM symbol containing the wake-up signal or the OFDM symbol used for wake-up signal transmission is a valid / usable wake-up signal OFDM symbol. This operation allows the UE to determine the starting position of the first wake-up signal listening time solely by the start point of the LO at the configured time slot level and the interval between the configured first wake-up signal MO and the LO start point. It no longer requires specifying the OFDM symbol at the start of the wake-up signal. The OFDM symbol where the wake-up signal is located within each MO or the OFDM symbol used for wake-up signal transmission is the valid / available wake-up signal OFDM symbol. The starting OFDM symbol of the wake-up signal within each MO is the first valid / available wake-up signal OFDM symbol within each MO. This operation can reduce signaling overhead.Optionally, the number of valid / available OFDM wake-up signal symbols within each MO is the same. This operation is applicable when the interval between adjacent wake-up signal MOs is equal to the number of OFDM symbols, and / or the starting position of a wake-up signal MO is equal to the starting position of an OFDM symbol, and / or the duration of a configured wake-up signal MO is equal to the number of OFDM symbols. Alternatively, the number of valid / available OFDM wake-up signal symbols within each MO is different. This operation is applicable when the interval between adjacent wake-up signal MOs is equal to the number of time slots, and / or the starting position of a wake-up signal MO is equal to the starting position of a time slot, and / or the duration of a configured wake-up signal MO is equal to the number of time slots.

[0191] In another alternative, the UE can also determine valid / available OFDM wake-up signal symbols based on a network-configured time-domain pattern indication and / or other configured signals and / or channels. The duration of the time-domain pattern is equal to the maximum period of all configured other signals and / or channels and / or other unicast signals and / or channels. The time-domain pattern can be a bitmap, where each bit corresponds to whether an associated OFDM symbol is occupied. This operation allows the UE to determine unoccupied OFDM symbols based on the configured time-domain pattern indicating resources occupied by other users' signals and / or channels or other unicast signals and / or channels, and then determine valid / available OFDM wake-up signal symbols based on the configured other signals and / or channels. In another alternative, the MOs corresponding to two adjacent sets of wake-up signal subgroups within a single LO can be non-contiguous. For example, within a LO, the time interval between the end position of the last MO associated with each wake-up signal subgroup set and the start position of one or more associated POs is greater than or equal to the wake-up delay associated with the wake-up signal subgroup set. The positions of other MOs associated with each wake-up signal subgroup set can be contiguous or non-contiguous. The MOs associated with different wake-up signal subgroup sets can be interleaved (e.g., some MOs in one subgroup set are earlier than some MOs in another subgroup set, while others are later than others in another subgroup set), or they can have a uniform order (e.g., all MOs in one subgroup set are earlier than all MOs in another subgroup set). The time interval between the end position of the LO and the start position of one or more associated POs is greater than or equal to the minimum wake-up delay reported by the UE. This operation can further reduce the paging latency for users supporting shorter wake-up delays.

[0192] In one embodiment, the UE determines the subgroup index in the associated subgroup set through the UE index (or UE identifier (UE ID)). For example, the subgroup index of the UE in the associated subgroup set is equal to 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 subgroups in a subgroup set, where U is a pre-configured or predefined integer, and U is greater than or equal to 1.

[0193] In one alternative, the UE determines the index of the associated wake-up signal subgroup subset within the associated set of wake-up signal subgroups using a UE index (or UE identifier (UE ID)). For example, the index of the associated subgroup subset within the UE's associated subgroup set is equal to floor(UE_ID / (N... Ns U)) mod P, where P is a pre-configured or predefined integer, greater than or equal to 1. Optionally, P is equal to the number of wake-up signal subgroups associated with a set of wake-up signal subgroups divided by the value of V, taking the upper bound. V is 2 raised to the power of the maximum information bit length supported by a wake-up signal. For example, if the maximum information bit length supported by a wake-up signal is k bits, then V=2. k P = ceil(G / V), where G is the number of wake-up signal subgroups associated with a set of wake-up signal subgroups. The UE determines the index of the wake-up signal subgroup in the associated set of wake-up signal subgroups through the UE index. For example, the index of the subgroup in the subgroup set associated with the UE is equal to floor(UE_ID / (N)). Ns U X)) mod Q, where Q is the number of wake-up signal subgroups in a subset, and Q is a pre-configured or predefined integer, greater than or equal to 1. Optionally, Q equals V.

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

[0195] In one alternative, 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 delay supported or reported by the UE, the UE listens to the PEI and / or periodically listens to the PO, and / or exits the wake-up signal listening process.

[0196] In one alternative, the UE listening to one or more Loops associated with one or more offsets may include all Loops that the UE listens to that are greater than or not less than the wake-up latency supported or reported by the UE, and / or until a UE-specific wake-up signal is received, and / or whichever is earlier. The UE-specific wake-up signal includes a wake-up signal carrying the index of the UE's subgroup or wake-up signals of all subgroups associated with the wake-up.

[0197] In one alternative, the UE listening to one or more Loops (LOs) associated with one or more offsets may include the UE listening to the LO associated with the largest offset configured by the network. If the UE detects a wake-up signal indicating that its subgroup has been woken up, the UE does not expect to listen to subsequent LOs associated with the Point of Purchase (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 its subgroup has been woken up, and if the second largest offset configured by the network is greater than or not less than the wake-up delay supported or reported by the UE, the UE listens to the LO associated with the second largest offset configured by the network. If the UE detects a wake-up signal indicating that its subgroup has been woken up, the UE does not expect to listen to subsequent LOs associated with the PO (the PO associated with the UE). This continues, optionally, until the offset associated with the LO is less than the wake-up delay supported or reported by the UE.

[0198] In one optional scheme, 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 delay supported or reported by the UE, the UE listens to all configured LOs. When the UE detects a wake-up signal indicating that the subgroup to which the UE belongs has been woken up, the UE listens to the first PO that meets the wake-up delay reported or supported by the UE. Optionally, 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 delay supported or reported by the UE includes any network-configured LO or all network-configured LOs whose interval between the end time unit and the start time unit of the associated PO being less than the wake-up delay supported or reported by the UE.

[0199] In one embodiment, the UE acquires the number of subgroups SN of each PO and / or the number of paging occasions LPON1 associated with each LO, or the number of POs LPON2 associated with one LO group via RRC configuration; or, the association between LOs and POs is determined based on the configured number of subgroups of each PO. For example, the UE determines that the number of POs LPON1 associated with each LO is (maxSN / SN), or the UE determines that the number of POs LPON2 associated with one LO group is floor((LON maxSN) / SN), where LON is the number of LOs in one LO group configured by the base station, LON is a pre-configured or pre-defined parameter value, and LON is greater than or equal to 1. Optionally, if LON is not configured, the default value of LON is 1. The PO index value POI associated with one LO group is ((UE_ID mod N) Ns+i_s)mod LPON2. The subgroup index i associated with the LO n , where 0<i n <SN, the UE determines the associated wake-up 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), the UE monitors the wake-up signal on the resource corresponding to the LO index in the associated LO group. If the UE detects the wake-up signal and the value of the information bit carried by the wake-up signal is equal to the associated wake-up signal subgroup index, or the information bit carried by the wake-up signal indicates that all subgroups associated with the LO are to be woken up, the UE monitors the PO and / or does not expect to monitor the wake-up signal. Wherein, the PO index i_s=floor(UE_ID / N) mod Ns, UE_ID is an 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), SNU is the number of subgroups grouped based on UE_ID in one PO, SNU is a pre-configured parameter value, maxSN is a pre-defined or pre-configured value, such as 32.

[0200] In an 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 with LPON=floor(maxSN / SN) consecutive POs within one DRX cycle. For example, when q=2, one LO can be associated with two consecutive POs within one DRX cycle. Compared with the case where one LO is associated with one PO, for example, compared with using 2 LOs to indicate 32 subgroups of 2 POs, this operation can use 1 LO to indicate 32 subgroups of 2 POs, which reduces the resource overhead of LOs. The wake-up signal subgroup index is i n , where 0<i n <SN, the UE determines the associated wake-up signal subgroup index as ((UE_ID mod N) Ns+i_s) mod LPON) SN+i n ) mod maxSN).

[0201] In an implementation, the UE acquires, through RRC configuration, the number of POs LPON2 associated with one LO group or the number of LOs LON within one LO group and / or the number of subgroups SN of each paging occasion. If LON is not configured and LPON2 is configured, one LO group can include cell((SN LPON2) / maxSN) LOs, where cell indicates ceiling. If LPON2 is not configured and LON is configured, the number of subgroups of LPON2 paging occasions shall satisfy SN LPON2 is greater than maxSN and SN LPON2 is less than maxSN the number of LOs, LPON2= floor((LON maxSN) / SN). For example, if the number of POs associated with one LO group is 3 and / or SN is 20, one LO group can include 2 LOs. When the number of subgroups of 3 POs, 60, is greater than 32 and less than 64, one LO group can be associated with 1.6 consecutive POs within one DRX cycle. Compared with the case where one LO is associated with one PO, for example, compared with using 3 LOs to indicate 60 subgroups of 3 POs, this operation can use 2 LOs to indicate 60 subgroups of 3 POs, which reduces the resource overhead of LOs.

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

[0203] In one embodiment, if SDT (Small Data Transmission) or RACH is in progress during the RRC inactive state and / or idle state, the UE does not expect to listen for wake-up signals or does not initiate wake-up signal listening.

[0204] In one embodiment, if an SDT or RACH procedure is in progress during the RRC inactive state and / or idle state, the UE does not expect to listen for wake-up signals or does not initiate wake-up signal listening, even if the wake-up signal listening conditions are met. The conditions for meeting wake-up signal listening include: the Reference Signal Received Power (RSRP) of the serving cell measured by the MR based on the SSB is greater than or equal to a threshold value 1 configured by the SIB; and / or the Reference Signal Received Quality (RSRQ) of the serving cell measured by the MR based on the SSB is greater than or equal to a threshold value 2 configured by the SIB; and / or the RSRP of the serving cell measured by the LR based on the LP-SS is greater than or equal to a threshold value 3 configured by the SIB; and / or the RSRQ of the serving cell measured by the LR based on the LP-SS is greater than or equal to a threshold value 4 configured by the SIB; and / or the RSRP of the serving cell measured by the LR based on the SSB is greater than or equal to a threshold value 5 configured by the SIB; and / or the RSRQ of the serving cell measured by the LR based on the SSB is greater than or equal to a threshold value 6 configured by the SIB.

[0205] In one embodiment, if the UE expects to send a RACH-related signal while listening for a wake-up signal, the RACH-related signal can be message 1 or message A. If the UE does not expect to listen for a wake-up signal or has stopped listening for a wake-up signal, the UE expects to send a RACH-related signal. The UE determines that the resource for sending the RACH-related signal is the nearest RO resource that satisfies the minimum wake-up delay. Optionally, the RACH is for establishing an RRC link.

[0206] In one alternative, if the UE expects to send RACH-related signals and / or SDT while listening for a wake-up signal, then the UE does not expect to listen for the wake-up signal, or stops listening for the wake-up signal, or pauses listening for the wake-up signal. The UE expects to send RACH-related signals and / or SDT, and / or the UE does not expect to listen for PO. Optionally, the RACH is not for establishing an RRC link or the RACH is for updating parameter configuration information in the SIB. Optionally, the UE determines that the resource for sending the SDT is the nearest CG-PUSCH resource after satisfying the minimum wake-up delay, if the SDT is CG-SDT. Optionally, the UE determines that the resource for sending RACH-related signals and / or SDT is the nearest RO resource after satisfying the minimum wake-up delay, if the SDT is RA-SDT. Here, sending the SDT can also be called performing the SDT. This operation takes into account that RACH-related signals and / or SDT are more important, but since the UE has not received a wake-up signal, sending only RACH-related signals and / or SDT after the MR is woken up and not listening for PO can save power consumption of listening for PDCCH. The UE's behavior after transmitting RACH-related signals and / or SDT may include one or more of the following combinations:

[0207] oUE expects to continue listening for wake-up signals;

[0208] oUE stops listening to PO;

[0209] If the measurements of MR and / or LR meet the wake-up signal listening conditions, the UE expects to enable or continue wake-up signal listening.

[0210] If the SDT schedules a DL SDT, the UE expects to continue listening for wake-up signals after receiving the DL SDT.

[0211] If the SDT schedules a DL SDT, after receiving the DL SDT, if the measurements of MR and / or LR meet the wake-up signal listening conditions, the UE expects to enable or continue wake-up signal listening.

[0212] If the SDT schedules a DL SDT, the UE starts a timer after receiving the DL SDT. If no DL SDT is received before the timer expires, the UE expects to enable or continue wake-up signal listening. If a DL SDT is received before the timer expires, the UE restarts or resets the timer. When the timer expires, the UE expects to enable or continue wake-up signal listening. Optionally, when the timer expires, if the measurements of MR and / or LR meet the wake-up signal listening conditions, the UE expects to enable or continue wake-up signal listening. The length of the timer is predefined or preconfigured.

[0213] In one alternative, if the UE expects to send RACH-related signals and / or SDT while listening for a wake-up signal, the UE is expected to listen for the wake-up signal, and the UE delays sending the RACH-related signals and / or SDT. Optionally, the RACH is not for establishing an RRC link or the RACH is for updating parameter configuration information in the SIB. After receiving the wake-up signal, the UE listens for the PO after satisfying the wake-up delay, and the UE sends the RACH-related signals and / or performs SDT transmission. This operation can reduce the power consumption caused by the UE enabling MR to send uplink signals while listening for the wake-up signal.

[0214] In one embodiment, if the UE does not receive a wake-up signal within a predefined or preconfigured duration, the UE stops listening for wake-up signals, listens for PEI and / or PO, and re-reports its capabilities. If the measurements of MR and / or LR meet the wake-up signal listening conditions, the UE starts listening for wake-up signals. At this time, the network regroups the UE based on the re-reported wake-up delay, and the UE determines the associated subgroup set and subgroup and / or subgroup subset based on the re-reported wake-up delay. This operation is applicable when the network receives an error indicating UE capabilities, causing the network to believe the UE does not exist and thus not instructing the UE to be woken up from its subgroup.

[0215] In one optional scheme, if the wake-up signal MO corresponding to the subgroup set index associated with the UE capability reported by the UE for wake-up delay is not configured, the UE determines the subgroup set index to be the index of the largest wake-up delay-associated wake-up signal subgroup set in the intersection of one or more wake-up delay-associated wake-up signal subgroup sets supported by the UE and one or more wake-up delay-associated wake-up signal subgroup sets configured by the network. This operation is applicable to scenarios where network errors in receiving UE capabilities lead to inconsistencies in the understanding of wake-up signal subgroup sets between the network and the UE.

[0216] In one alternative approach, if the wake-up signal MO corresponding to the subgroup set index associated with the UE capability reported by the UE for wake-up delay is not configured, and the intersection of one or more wake-up signal subgroup sets associated with wake-up delay supported by the UE and one or more wake-up signal subgroup sets associated with wake-up delay configured by the network is an empty set, the UE stops listening for wake-up signals, listens for PEI and / or PO, and re-reports the UE capability. If the measurements of MR and / or LR meet the wake-up signal listening conditions, the UE enables wake-up signal listening. At this time, the network regroups based on the wake-up delay re-reported by the UE, and the UE determines the associated subgroup set and subgroup and / or subgroup subset based on the re-reported wake-up delay. This operation is applicable when the UE cannot enable MR listening to PO within the configured wake-up delay.

[0217] In one embodiment, a LO is associated with a PO within a DRX cycle; for example, the LO cycle and the DRX cycle are the same. Considering that the size of a UE's paging message may exceed the size of a single data packet, the paging message may be divided into multiple data packets or data fragments for transmission. When the UE receives a wake-up signal and / or the wake-up signal triggers paging listening, the UE listens for POs within Y consecutive DRX cycles, and does not wish to listen for LOs associated with POs within those Y DRX cycles, and / or does not wish to enable wake-up signal listening. Optionally, the non-desire to enable wake-up signal listening may be a non-desire to enable wake-up signal listening for a duration of Y consecutive DRX cycles.

[0218] In another aspect, we will introduce the UE behavior when only some of the multiple wake-up signal listening conditions are met, and / or the UE behavior when the wake-up signal listening conditions and RRM measurement conditions are different.

[0219] In one embodiment, if the RSRP and / or RSRQ of the serving cell measured by MR are greater than the threshold values ​​configured by SIB respectively, and the RSRP and / or RSRQ of the serving cell measured by LR are less than the threshold values ​​configured by SIB respectively, the UE's behavior may include one or more of the following combinations:

[0220] oUE does not expect to listen for wake-up signals; UE still listens for PEI and / or listens for PO.

[0221] The UE can perform RRM measurements of the serving cell on the LR based on LP-SS and / or SSB until the measurements of MR and / or LR meet the wake-up signal listening conditions. The UE then starts listening to the wake-up signal and stops listening to PO before receiving a wake-up signal indicating wake-up.

[0222] oMR can perform relaxed RRM measurements or not perform RRM measurements at all. This operation is to reduce power consumption when LR and MR are enabled simultaneously;

[0223] The UE does not perform RRM measurements of the serving cell on the LR based on LP-SS and / or SSB. After a pre-configured or predefined duration, the UE enables LR and / or performs RRM measurements of the serving cell on the LR based on LP-SS and / or SSB until the measurements of MR and / or LR meet the wake-up signal listening conditions. At this point, the UE enables wake-up signal listening and stops listening to PO until a wake-up signal indication is received. Optionally, during the duration, the MR may perform relaxed RRM measurements. This operation aims to reduce the MR measurement frequency when the MR measurements meet the wake-up signal listening conditions, thereby reducing the UE's power consumption.

[0224] In one embodiment, if the conditions for RRM measurement offloading are met, or after the UE enables wake-up signal listening, the UE does not send periodic SRS signals and does not measure DL PRS. This operation is to reduce the additional power loss caused by the MR in a deep sleep state being woken up to send periodic reference signals or perform DL PRS measurements.

[0225] In one embodiment, if the measurements of the MR and / or LR satisfy the wake-up signal listening condition and the measurements of the MR and / or LR satisfy the RRM measurement offload condition, the UE listens for the wake-up signal and performs the serving cell's RRM measurement on the LR based on the LP-SS and / or SSB, and the MR enters a deep sleep state. If the measurements of the MR and / or LR satisfy the wake-up signal listening condition but do not satisfy the RRM measurement offload condition, and if the measurements of the MR and / or LR satisfy the condition for enabling relaxed RRM measurement of the MR, the UE listens for the wake-up signal, performs relaxed RRM measurement of the serving cell and / or neighboring cells on the MR, and / or the UE performs the serving cell's RRM measurement on the LR based on the LP-SS and / or SSB, and / or the MR does not enter a deep sleep state. This operation can utilize the RRM measurement performed on the LR to assist the MR's RRM measurement, thus allowing the MR to perform relaxed RRM measurement, further reducing the power loss caused by the MR performing RRM measurement. If the measurements of MR and / or LR meet the wake-up signal listening conditions, the measurements of MR and / or LR do not meet the RRM measurement offloading conditions, the measurements of MR and / or LR do not meet the RRM measurement enabling conditions for MR relaxation, the UE listens to LP-WUS, the UE does not perform RRM measurements of the serving cell on LR based on LP-SS and / or SSB, and / or the UE performs RRM measurements of the serving cell and neighboring cells on MR based on SSB, the MR does not enter a deep sleep state.
