[0002] In order 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 quasi-5G communication systems. Therefore, 5G or quasi-5G communication systems are also referred to as "super 4G networks" or "post-LTE systems."

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

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

[0062] Figure 1 An example wireless network 100 is shown in accordance with various embodiments of the present disclosure. Figure 1 The embodiment of the wireless network 100 shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 can be used without departing from the scope of the present disclosure.

[0063] Wireless network 100 includes gNodeB (gNB) 101, gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one Internet Protocol (IP) network 130, such as the Internet, a private IP network, or other data network.

[0064] Depending on the network type, other well-known terms such as "base station" or "access point" can be used instead of "gNodeB" or "gNB". For convenience, the terms "gNodeB" and "gNB" are used in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Also, depending on the network type, other well-known terms such as "mobile station", "subscriber station", "remote terminal", "wireless terminal" or "user device" can be used instead of "user equipment" or "UE". For convenience, the terms "user equipment" and "UE" are used in this patent document to refer to a remote wireless device that wirelessly accesses a gNB, whether the UE is a mobile device (such as a mobile phone or smartphone) or a commonly thought of fixed device (such as a desktop computer or vending machine).

[0065] gNB 102 provides wireless broadband access to network 130 for a first plurality of user equipment (UE) within coverage area 120 of gNB 102. The first plurality of UEs include: UE 111, which may be located in a small business (SB); UE 112, which may be located in an enterprise (E); UE 113, which may be located in a WiFi hotspot (HS); UE 114, which may be located in a first residence (R); UE 115, which may be located in a second residence (R); UE 116, which may be a mobile device (M), such as a cellular phone, a wireless laptop, a wireless PDA, etc. gNB 103 provides wireless broadband access to network 130 for a second plurality of UEs within coverage area 125 of gNB 103. The second plurality of UEs include UE 115 and UE 116. In some embodiments, one or more of gNBs 101-103 may be capable of communicating with each other and with UEs 111-116 using 5G, long term evolution (LTE), LTE-A, WiMAX, or other advanced wireless communication technologies.

[0066] The dashed lines illustrate the approximate extents of coverage areas 120 and 125, which are shown as approximately circular for purposes of illustration and explanation only. It should be clearly understood that coverage areas associated with gNBs, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.

[0067] As described in more detail below, one or more of gNB 101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, one or more of gNB 101, gNB 102, and gNB 103 support codebook design and structure for a system with a 2D antenna array.

[0068] although Figure 1 One example of a wireless network 100 is shown, but Figure 1 Various changes may be made. For example, wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Also, gNB 101 can communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. In addition, gNBs 101, 102, and / or 103 can provide access to other or additional external networks, such as an external telephone network or other type of data network.

[0069] Figure 2a and Figure 2b Example wireless transmit and receive paths according to the present disclosure are shown. In the following description, transmit path 200 can be described as being implemented in a gNB (such as gNB 102) and receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that receive path 250 can be implemented in a gNB and transmit path 200 can be implemented in a UE. In some embodiments, receive path 250 is configured to support codebook design and structure for a system with a 2D antenna array as described in embodiments of the present disclosure.

[0070] The transmit path 200 includes a channel coding and modulation block 205, a serial to parallel (S to P) block 210, an N-point inverse fast Fourier transform (IFFT) block 215, a parallel to serial (P to S) block 220, an add cyclic prefix block 225, and an upconverter (UC) 230. The receive path 250 includes a downconverter (DC) 255, a remove cyclic prefix block 260, a serial to parallel (S to P) block 265, an N-point fast Fourier transform (FFT) block 270, a parallel to serial (P to S) block 275, and a channel decoding and demodulation block 280.

[0071] In the transmit path 200, the channel coding and modulation block 205 receives a set of information bits, applies coding (such as low-density parity check (LDPC) coding), and modulates the input bits (such as using quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM)) to generate a sequence of frequency-domain modulation symbols. The serial-to-parallel (S-to-P) block 210 converts (such as demultiplexes) the serial modulation symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points used in the gNB 102 and the UE 116. The N-point IFFT block 215 performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. The parallel-to-serial block 220 converts (such as multiplexes) the parallel time-domain output symbols from the N-point IFFT block 215 to generate a serial time-domain signal. The add cyclic prefix block 225 inserts a cyclic prefix into the time-domain signal. The up-converter 230 modulates (such as up-converts) the output of the add cyclic prefix block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at baseband before conversion to RF frequency.

[0072] The RF signal transmitted from gNB 102 arrives at UE 116 after passing through a wireless channel, and an operation opposite to that at gNB 102 is performed at UE 116. Downconverter 255 downconverts the received signal to a baseband frequency, and remove cyclic prefix block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel block 265 converts the time-domain baseband signal into a parallel time-domain signal. N-point FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. Parallel-to-serial block 275 converts the parallel frequency-domain signals into a sequence of modulated data symbols. Channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0073] Each of gNBs 101-103 may implement a transmit path 200 similar to that for transmitting in the downlink to UEs 111-116 and may implement a receive path 250 similar to that for receiving in the uplink from UEs 111-116. Similarly, each of UEs 111-116 may implement a transmit path 200 for transmitting in the uplink to gNBs 101-103 and may implement a receive path 250 for receiving in the downlink from gNBs 101-103.

[0074] Figure 2a and Figure 2b Each of the components in can be implemented using hardware only, or a combination of hardware and software / firmware. As a specific example, Figure 2a and Figure 2b At least some of the components in can be implemented with software, while other components can be implemented by configurable hardware or a mixture of software and configurable hardware. For example, FFT block 270 and IFFT block 215 can be implemented as a configurable software algorithm, in which the value of the number of points N can be modified according to the implementation.

[0075] In addition, although described as using FFT and IFFT, this is illustrative only and should not be construed as limiting the scope of the present disclosure. Other types of transforms can be used, such as discrete Fourier transform (DFT) and inverse discrete Fourier transform (IDFT) functions. It should be understood that for DFT and IDFT functions, the value of variable N can be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N can be any integer as a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0076] although Figure 2a and Figure 2b An example of a wireless transmit and receive path is shown, but the Figure 2a and Figure 2b Make various changes. For example, Figure 2a and Figure 2b The various components in can be combined, further subdivided or omitted, and additional components can be added according to specific needs. Figure 2a and Figure 2b It is intended to illustrate examples of the types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communications in a wireless network.

[0077] Figure 3a An example UE 116 according to the present disclosure is shown. Figure 3a The embodiment of UE 116 shown in FIG. 1 is for illustration only, and Figure 1 UEs 111-115 can have the same or similar configurations. However, UEs have a variety of configurations, and Figure 3a The scope of the present disclosure is not limited to any particular implementation of the UE.

[0078] UE 116 includes antenna 305, radio frequency (RF) transceiver 310, transmit (TX) processing circuit 315, microphone 320, and receive (RX) processing circuit 325. UE 116 also includes speaker 330, processor / controller 340, input / output (I / O) interface 345, input device(s) 350, display 355, and memory 360. Memory 360 includes operating system (OS) 361 and one or more applications 362.

[0079] The RF transceiver 310 receives incoming RF signals from the antenna 305 transmitted by the gNB of the wireless network 100. The RF transceiver 310 downconverts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to the RX processing circuit 325, where the RX processing circuit 325 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. The RX processing circuit 325 sends the processed baseband signal to the speaker 330 (such as for voice data) or to the processor / controller 340 (such as for web browsing data) for further processing.

[0080] The TX processing circuit 315 receives analog or digital voice data from the microphone 320, or receives other outgoing baseband data (such as network data, email, or interactive video game data) from the processor / controller 340. The TX processing circuit 315 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 310 receives the outgoing processed baseband or IF signal from the TX processing circuit 315 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 305.

[0081] The processor / controller 340 can include one or more processors or other processing devices and execute an OS 361 stored in the memory 360 to control the overall operation of the UE 116. For example, the processor / controller 340 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceiver 310, the RX processing circuit 325, and the TX processing circuit 315 according to well-known principles. In some embodiments, the processor / controller 340 includes at least one microprocessor or microcontroller.

[0082] The processor / controller 340 is also capable of executing other processes and programs resident in the memory 360, such as operations for channel quality measurement and reporting for a system with a 2D antenna array as described in the embodiments of the present disclosure. The processor / controller 340 is capable of moving data into or out of the memory 360 as needed for the executed process. In some embodiments, the processor / controller 340 is configured to execute applications 362 based on the OS 361 or in response to signals received from the gNB or operator. The processor / controller 340 is also coupled to the I / O interface 345, where the I / O interface 345 provides the UE 116 with the ability to connect to other devices such as laptops and handheld computers. The I / O interface 345 is the communication path between these accessories and the processor / controller 340.

[0083] Processor / controller 340 is also coupled to input device(s) 350 and display 355. An operator of UE 116 can input data into UE 116 using input device(s) 350. Display 355 can be a liquid crystal display or other display capable of presenting text and / or at least limited graphics (such as from a website). Memory 360 is coupled to processor / controller 340. A portion of memory 360 can include random access memory (RAM), while another portion of memory 360 can include flash memory or other read-only memory (ROM).

[0084] although Figure 3a An example of UE 116 is shown, but it is possible to Figure 3a Make various changes. For example, Figure 3a The various components in can be combined, further subdivided, or omitted, and additional components can be added according to specific needs. As a specific example, processor / controller 340 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Moreover, although Figure 3a The UE 116 is shown configured as a mobile phone or smart phone, but the UE can be configured to operate as other types of mobile or stationary devices.

[0085] Figure 3bAn example gNB 102 according to the present disclosure is shown. Figure 3b The embodiment of the gNB 102 shown in FIG. is for illustration only, and Figure 1 Other gNBs can have the same or similar configurations. However, gNBs have a variety of configurations, and Figure 3b The scope of the present disclosure is not limited to any particular implementation of the gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structure as gNB 102.

[0086] like Figure 3b As shown in FIG. 1 , gNB 102 includes multiple antennas 370a-370n, multiple RF transceivers 372a-372n, transmit (TX) processing circuitry 374, and receive (RX) processing circuitry 376. In some embodiments, one or more of the multiple antennas 370a-370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0087] The RF transceivers 372a-372n receive incoming RF signals from the antennas 370a-370n, such as signals transmitted by a UE or other gNB. The RF transceivers 372a-372n downconvert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to the RX processing circuitry 376, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The RX processing circuitry 376 sends the processed baseband signals to the controller / processor 378 for further processing.

[0088] The TX processing circuit 374 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from the controller / processor 378. The TX processing circuit 374 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceivers 372a-372n receive the outgoing processed baseband or IF signals from the TX processing circuit 374 and up-convert the baseband or IF signals to RF signals that are transmitted via the antennas 370a-370n.

[0089] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceivers 372a-372n, the RX processing circuitry 376, and the TX processing circuitry 374 in accordance with well-known principles. The controller / processor 378 can also support additional functionality, such as more advanced wireless communication functionality. For example, the controller / processor 378 can perform a Blind Interference Sensing (BIS) process, such as performed through a Blind Interference Sensing (BIS) algorithm, and decode a received signal with an interference signal subtracted. The controller / processor 378 can support any of a variety of other functions in the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0090] The controller / processor 378 can also execute programs and other processes resident in the memory 380, such as a basic OS. The controller / processor 378 can also support channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. In some embodiments, the controller / processor 378 supports communications between entities such as web RTC. The controller / processor 378 can move data into or out of the memory 380 as needed by the executing process.

[0091] The controller / processor 378 is also coupled to a backhaul or network interface 382. The backhaul or network interface 382 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or via a network. The backhaul or network interface 382 can support communication via any suitable (multiple) wired or wireless connections. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G or new radio access technology or NR, LTE or LTE-A), the backhaul or network interface 382 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow the gNB 102 to communicate with a larger network (such as the Internet) via a wired or wireless local area network or via a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication via a wired or wireless connection, such as an Ethernet or RF transceiver.

[0092] The memory 380 is coupled to the controller / processor 378. A portion of the memory 380 can include RAM, while another portion of the memory 380 can include flash memory or other ROM. In some embodiments, a plurality of instructions such as a BIS algorithm are stored in the memory. The plurality of instructions are configured to cause the controller / processor 378 to perform the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.

[0093] As described in more detail below, the transmit and receive paths of gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuitry 374, and / or RX processing circuitry 376) support aggregated communications with FDD cells and TDD cells.

[0094] although Figure 3b An example of a gNB 102 is shown, but the Figure 3b For example, gNB 102 can include any number of Figure 3a . As a specific example, an access point can include a number of backhaul or network interfaces 382, ​​and the controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, while shown as including a single instance of TX processing circuitry 374 and a single instance of RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0095] The time domain unit (also called time unit) in the present application can be: an OFDM symbol, an OFDM symbol group (consisting of multiple OFDM symbols), a time slot, a time slot group (consisting of multiple time slots), a subframe, a subframe group (consisting of multiple subframes), a system frame, a system frame group (consisting of multiple system frames); it can also be an absolute time unit, such as 1 millisecond, 1 second, etc.; the time unit can also be a combination of multiple granularities, such as N1 time slots plus N2 OFDM symbols.

[0096] The frequency domain unit (also called frequency unit) in the present application can be: a subcarrier, a subcarrier group (consisting of multiple subcarriers), a resource block (resource block, RB), which can also be called a physical resource block (physicalresource block, PRB), a resource block group (consisting of multiple RBs), a bandwidth part (bandwidth part, BWP), a band part group (consisting of multiple BWPs), a band / carrier, a band group / carrier group; it can also be an absolute frequency domain unit, such as 1 Hz, 1 kHz, etc.; the frequency domain unit can also be a combination of multiple granularities, such as M1 PRBs plus M2 subcarriers.

[0097] Exemplary embodiments of the present disclosure are further described below in conjunction with the accompanying drawings.

[0098] The text and drawings are provided as examples only to help readers understand the present disclosure. They are not intended and should not be interpreted as limiting the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, it is obvious to those skilled in the art based on what is disclosed herein that the embodiments and examples shown may be changed without departing from the scope of the present disclosure.

[0099] The transmission links of the wireless communication system mainly include: a downlink communication link from the 5G New Radio (NR) gNB to the user equipment (UE), an uplink communication link from the UE to the network, and a sidelink communication link from the UE to the UE.

[0100] In a wireless communication system, for example, in a current wireless communication system, in order to reduce the energy consumption on the terminal side, a discontinuous reception (DRX) mechanism is introduced, so that the UE can be in a sleep state for most of the time, and only needs to be awakened periodically to monitor the paging occasion (PO). In a DRX cycle, the UE only wakes up during the DRX activation duration (DRX ON duration) to monitor the PO. After monitoring the PDCCH scrambled by the P-RNTI, the UE continues to read the paged terminal flag in the paging message. If the read terminal flag is the same as its own flag, the UE further reads the paging message, otherwise, the paging message is discarded. In the above process, in order to further reduce the energy consumption of the UE, a paging early indication (PEI) signal is introduced to indicate whether the UE needs to monitor the corresponding PO. If the system information provides a PEI configuration, the UE monitors a PEI occasion (PEI occasion) once in each DRX cycle. If the UE detects a PEI indication and the PEI indicates that the UE monitors the associated PO, the UE should wake up at the next PO to monitor the PO; otherwise, the UE does not need to wake up to monitor the PO.

[0101] In order to determine whether the UE can temporarily reside in a non-serving cell, the UE performs RRM measurements based on the synchronization signal (SS) and the physical broadcast channel (PBCH) block (SSB). If the RRM measurement results based on the SSB meet the cell selection and / or cell reselection principles, the UE performs cell selection and / or cell reselection. If there is a non-serving cell whose cell selection reception level value and / or cell selection quality value calculated by the RRM measurement results based on the SSB within a predefined or preconfigured duration is greater than the predefined or preconfigured threshold value, the UE can temporarily reside in the current cell. If there are multiple non-serving cells whose cell selection reception level value and / or cell selection quality value calculated by the RRM measurement results based on the SSB within a predefined or preconfigured duration is greater than the predefined or preconfigured threshold value, the UE selects the cell on the highest priority frequency that meets the standard.

[0102] In some use cases with stricter requirements on UE low energy consumption (such as IoT devices and / or wearable devices), in order to further extend the battery life of the UE, a new low-power synchronization signal is designed to perform RRM measurements. Therefore, the RRM measurement process needs to be improved.

[0103] Optionally, the new low-power synchronization signal may also be used to wake up the UE. Furthermore, it is also necessary to improve the configuration and monitoring process of the new low-power synchronization signal.

[0104] Figure 4 FIG. 4 is a schematic diagram showing a method 400 executed by a user equipment UE in a communication system according to an embodiment of the present disclosure. Figure 4 As shown, the method 400 includes:

[0105] 401: Receive configuration information of a first signal. Optionally, receive the configuration information of the first signal through RRC signaling.

[0106] 402: When it is determined based on the configuration information that the reference signal received power and / or the reference signal received quality of the first signal meets the first condition, perform radio resource management RRM measurement based on the first signal, and optionally determine the signal for performing the RRM measurement according to the first condition and / or the second condition, and

[0107] 403: When it is determined based on the configuration information that the reference signal reception power and / or the reference signal reception quality of the first signal do not meet the first condition, perform RRM measurement based on the synchronization signal and the physical broadcast channel block SSB, and optionally, determine whether to perform cell selection or reselection based on the results of the RRM measurement of the first signal and / or the second signal and a predefined or preconfigured threshold value.

[0108] Specifically, in the present invention, a method and device for configuring and transmitting a low-power synchronization signal will be introduced. In one embodiment of the present invention, the method will be introduced to determine the configuration of the first signal, the monitoring method, and the method for measuring radio resource management (RRM). The first signal includes at least one of the following: a low-power wake-up signal (Low Power Wake Up Signal, LPWUS), a low-power synchronization signal (Lower Power synchronization signal, LP-SS), SSB, a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a PBCH demodulation reference signal (DMRS), and a tracking reference signal (TRS). In this embodiment, the first signal is used for exemplary introduction, and the introduced method can also be used for the configuration and transmission of other signals.

[0109] The receiver of the UE includes two modules, one is the main wireless communication module (Main Radio, MR), which is used to receive the regular signal / channel sent by the base station, and the other is the low power wake-up signal receiving module (Lower Power Wake Up Receiver, LR), which is used to receive the first signal sent by the base station. The reason why the dedicated module is used to receive the first signal is that the first signal is based on the existing NR system based on the orthogonal frequency division multiplexing (OFDM) waveform and is further based on the amplitude shift keying (ASK) modulation and / or frequency shift keying (FSK) modulation. The LR can receive or monitor the first signal at extremely low power and perform RRM measurement. Optionally, the first signal can also be used to wake up the UE, that is, once the UE monitors the first signal, the LR can trigger the MR to switch from the sleep period to the activation period, so that specific operations can be performed. Optionally, on-off keying (OOK) modulation is a special case of amplitude shift keying (ASK) modulation.

[0110] 1. Configuration of the first signal resource

[0111] The UE may use the first signal to reduce power consumption. The UE obtains configuration information of the first signal by receiving a radio resource control RRC message and / or a high-level parameter. If the configuration information of the first signal is provided by an RRC message and / or a high-level parameter, a UE supporting the first signal may monitor the first signal using the first signal configuration parameters configured in the RRC message and / or the high-level parameter. Optionally, in the RRC INACTIVE and / or IDLE state, the first signal may be configured in the SIB and / or MIB and / or SDT. Optionally, in the RRC IDLE state, the first signal may be configured in a high-level parameter.

[0113] o Information bit length (payload size), optional, used to indicate the cell index and / or

[0114] UE or UE group index;

[0115] o Whether to monitor the first signal across cells or only in the current cell. When the value of whether to monitor the first signal across cells is "true" or "on" or the monitoring of the first signal only in the current cell is "false" or "off" or not configured in the RRC message, the UE can monitor the first signal in the temporary cell; when the value of whether to monitor the first signal across cells is "false" or "off" or the monitoring of the first signal only in the current cell is "true" or "on", the UE only monitors the first signal in the cell where the RRC connection is released if the UE recently received a release RRC connection message without a non-last cell update;

[0116] o Modulation mode, the modulation mode includes at least one of the following: OOK, FSK, OFDMA.

[0117] When the UE reports one or more modulation modes supported by the UE, that is, UE capabilities, it is used to indicate the modulation mode of the enabled first signal, so as to avoid the problem of inconsistent understanding of the modulation mode of the first signal between the base station and the UE.

[0120] oThe period of the first signal can be at least one of the following: 160ms, 320ms,

[0121] 480ms, 960ms. Optionally, the period is the same as the period of PO; Optionally, LP-

[0122] The period of SS can be configured according to the period of SSB, and can be configured as W times of the SSB period, where W is a real number greater than 0, W can be less than 1, and optionally, W=1; o is used to wake up the UE, indicating whether the UE monitors the time domain starting position or ending position of the first signal of the corresponding PO, which is related to the starting position of PO, and optionally, within a predefined or preconfigured time interval before the starting position of PO.

[0123] o Operation mode information, the operation mode information may include at least one of the following: in-band transmission, guard band transmission, separate band transmission. If the first signal is configured for in-band transmission, the UE may be instructed that the first signal and the NR signal and / or channel share the same physical cell index, or that the first signal and the NR signal and / or channel share different physical cell indexes. When the first signal and the NR signal and / or channel share the same physical cell index, the UE assumes that the number of first signal ports and SSB ports is the same.

[0124] o The average number of first signals used for cell measurement. If the average number of first signals used for cell measurement is not configured, the highest beam measurement value is used as the cell measurement value.

[0125] Otherwise, the cell measurement amount is a linear average of at most the number of the average first signals used for cell measurement the highest beam measurement power values.

[0126] o Indicates the measurement quantity that the UE is requested to report, and the optional measurement quantity may include at least one of the following: RSSI, RSRP, SINR, RSRQ.

[0127] o subcarrier spacing of the first signal, optionally, the subcarrier spacing of the first signal is equal to the subcarrier spacing of the initial downlink BWP or CORESET0;

[0128] o an antenna port for a first signal; a configuration method for the first signal antenna port may include a combination of one or more of the following:

[0129] n The UE assumes that all resource elements used for the first signal transmission within a given time unit or OFDM symbol duration of a (pre-)configured or predefined sequence length use the same antenna port;

[0130] nIf there is no explicit signaling indication of the first signal antenna port configuration, and / or if the base station configures only one TRS or LP-SS or SSB port, the UE may assume that the transmission of all time units in which the first signal is located uses the same antenna port;

[0131] nIf there is no explicit signaling indication of the antenna port configuration of the first signal, and / or if the base station configures multiple TRS or LP-SS or SSB ports, the UE may assume that the same antenna port is used in T consecutive time units starting from the first time unit of the first signal transmission. The association relationship between the first signal and the configured multiple TRS or LP-SS or SSB ports is determined by the quasi-co-location QCL relationship of the first signal.

[0132] nIf the first signal is configured with only one antenna port, the UE may assume that the transmission of all time units in which the first signal is located uses the same antenna port;

[0133] nIf the first signal is configured with multiple antenna ports, the UE may assume that the same antenna port is used in T consecutive time units starting from the first time unit of the first signal transmission. The association relationship between the first signal and the configured multiple TRS or LP-SS or SSB ports is determined by the quasi-co-location QCL relationship of the first signal.

[0134] nOptionally, the time unit is a downlink time unit;

[0135] nThe T may be a parameter value (pre)configured or predefined by the base station device and / or reported by the UE according to its own processing capability. Wherein, T is a natural number, and T is greater than or equal to 1. oThe power control offset relative to SSB, that is, the ratio of the first signal EPRE (Energy per resource element) to the SSB EPRE, may include at least one of the following values: -3dB, 0dB, 3dB, 6dB. The value is a multiple of 3, mainly because a power increase of 3dB is equivalent to a power increase of 2 times the original power, and a power reduction of 3dB is equivalent to a power decrease of 1 / 2 of the original power. If the power control offset relative to SSB is not provided or configured, the UE assumes that the value of the offset is 0dB, that is, the EPRE of the first signal is equal to the EPRE of the SSB. The offset applies to the first signal resource or all resources in the resource set.

[0136] oThe method for determining the quasi co-site QCL relationship of the first signal may include a combination of one or more of the following:

[0147] QCL relationship of “typeC”;

[0148] n The UE desires to be indicated that the first signal and the SSB have a QCL of 'typeD'. Optionally, the SSB may have a physical cell ID (PCI) different from the PCI of the serving cell.

[0149] For SSBs from the serving cell and SSBs with a different PCI than the serving cell,

[0150] The UE may assume that the center frequency, SCS, and SFN offset are the same.

[0151] The pseudo-random sequence generator for generating the first signal should be initialized in each OFDM symbol or each time slot. The mapping method of the sequence of the first signal may include a combination of one or more of the following:

[0152] o The UE determines that the first signal is in-band and

[0153] Resource mapping and / or transmission is performed on a protection band or a separate band. On the indicated carrier, the first signal sequence is mapped to a time unit in the actual first signal duration, and the first signal sequence should be mapped to a resource element (k, l), starting from the 0th element value of the sequence, on the allocated 12*m subcarriers, first arranged in ascending order of subcarrier index k=0,1,…,12*m-1, and then in each time unit, the first signal is transmitted with OFDM index l=2,3,…, or l=4,5,…n*14-1; wherein m is the number of PRBs mapped by the first signal sequence, and n is the number of time slots mapped by the first signal sequence.

[0156] o In the frequency domain unit, a resource element of the first signal is mapped every L subcarriers,

[0157] In order to achieve the effect of repeated transmission in the time domain, the coverage of the first signal is expanded. Optionally, L=1.

[0159] The UE may increase the coverage of the first signal by performing a receiving-end frequency hopping method. The method by which the UE performs receiving-end frequency hopping may include a combination of one or more of the following:

[0160] o In the frequency domain unit, the UE is configured to perform receiving-end frequency domain hopping based on a resource or time unit of a first signal, where the resource of the first signal may be the n time units mapped to the first signal sequence, and / or the m physical resource blocks.

[0161] o According to the maximum duration of the first signal configured by higher layer signaling or RRC or SIB, the UE expects to receive all hops of the first signal using frequency domain hopping within the maximum duration of the first signal.

[0162] o Optionally, within the maximum duration of the first signal, when the maximum duration of the first signal for RRM measurement or the repetition of the first signal in the time domain and the first signal for wake-up are transmitted overlapped, the UE does not expect to receive the first signal for RRM measurement other than the first signal for wake-up using frequency domain hopping.

[0163] 2. UE's behavior when it detects / cannot detect the first signal used for wake-up

[0164] The UE assumes that no more than one first signal sequence is sent on each first signal resource within a given time. The behavior of the UE monitoring the first signal for waking up may include a combination of one or more of the following:

[0165] o If the UE detects the first signal, optionally, if extended DRX is used and the UE detects the first signal, the UE wakes up and listens to the next X PO(s) or PO(s) for a predefined or preconfigured duration, and / or until a UE-specific paging message is received, and / or whichever is earlier.

[0166] oOptional, such as Figure 7 As shown in (a), the subsequent X PO(s) or PO(s) within a predefined or preconfigured duration can be mapped to one first signal, that is, the UE listens to the first signal within a predefined or preconfigured time unit before the starting position of the X POs or the predefined or preconfigured duration. If the UE detects the first signal, the UE wakes up to listen to the subsequent X PO(s) or PO(s) within a predefined or preconfigured duration, and / or until a UE-specific paging message is received.

[0167] and / or whichever is earlier.

[0168] oOptional, such as Figure 7 As shown in (b), the first signal may carry 1 bit of indication information, indicating whether the UE monitors the PEI within a predefined or preconfigured duration, or indicating whether the UE wakes up to monitor the subsequent X PO(s) or the PO(s) within a predefined or preconfigured duration. Optionally, during the duration, the UE does not monitor the SSB, and this solution can reduce the power overhead caused by monitoring the SSB;

[0169] o Optionally, the subsequent X PO(s) may be subsequent X consecutive PO(s)

[0170] Mapped to X first signals, that is, the UE listens to the first signal within a predefined or preconfigured time unit before the start position of each PO. When the UE detects the first signal, the UE wakes up to listen to the subsequent Q consecutive PO(s) or PO(s) within a predefined or preconfigured duration, and / or until a UE-specific paging message is received, and / or whichever is earlier. When the UE listens to the subsequent Q PO(s), the UE does not listen to its associated first signal, such as Figure 7 (c) where Q is less than X.

[0171] o Optionally, the subsequent X PO(s) are within a periodic paging time window (PTW) configured for the UE.

[0172] o The X and Q may be parameter values ​​(pre)configured or predefined by the base station device and / or reported by the UE according to its own processing capability. Wherein, X and Q are natural numbers, and X and Q are greater than or equal to 1.

[0173] If the UE cannot monitor the first signal corresponding to its PO, such as during cell reselection, the UE wakes up to monitor each or associated PO. Optionally, if the UE cannot monitor the first signal corresponding to its PO, such as during cell reselection, the UE wakes up to monitor each or associated PO until the start of the next first signal or until the end of the PTW, whichever is earlier.

[0174] 3. RRM measurement

[0175] In multi-beam operation, the UE assumes that the same first signal is repeatedly transmitted on all transmit beams, and the beam used to receive the first signal depends on the UE implementation.

[0176] The downlink first signal transmit power is defined as the linear average over the power contributions (in [W]) of the resource elements carrying the configured first signal within the operating system bandwidth. The EPRE of the downlink first signal may be derived from the SSB transmit power and the configured power control offset relative to the SSB. The RSRP measurement result of the first signal shall be greater than or equal to a predefined or preconfigured threshold value.

[0177] When the first condition is met, the UE may perform RRM measurement based on the configured first signal, otherwise, the UE performs RRM measurement based on the SSB. The RRM measurement may be an RRM measurement of a serving cell and / or a neighboring cell and / or a temporary cell. The first condition may include a combination of one or more of the following:

[0178] oWhen in RRC INACTIVE and / or IDLE state;

[0179] o If the reference cell selection RX level value (Srxlev) of the serving cell minus the Srxlev calculated based on the RSRP of the first signal is less than or equal to T1; after cell selection or cell reselection to a new cell, or if the Srxlev calculated based on the RSRP of the first signal is greater than the reference Srxlev of the serving cell, the UE shall set the reference Srxlev of the serving cell to the Srxlev calculated based on the RSRP of the first signal.

[0180] o If the Z consecutive RSRPs based on the first signal are greater than or not less than (in this article,

[0181] (Can be used interchangeably with greater than or equal to) T2 and / or when the continuous V RSRQs based on the first signal are greater than or not less than T3, the UE performs RRM measurement based on the first signal. If the continuous Z RSRPs based on the first signal are less than T2 and / or the continuous V RSRQs based on the first signal are less than T3, the UE performs RRM measurement based on SSB. Wherein, Z and V are preconfigured or predefined values, and optionally, Z = V. At this time, the RRM based on the first signal is caused by the UE being at the edge of the cell and the insufficient coverage of the first signal.

[0182] The measurement is inaccurate, therefore, an SSB with a larger coverage is used to perform RRM measurement; o If the RSRP of the first signal is greater than or not less than T4 and / or the RSRQ of the first signal is greater than or not less than T5, or if the Srxlev calculated based on the RSRP of the first signal is greater than or not less than T6 and / or the cell selection quality value (cellSelection quality value, Squal) calculated based on the RSRQ of the first signal is greater than or not less than T7, the UE performs RRM measurement based on the first signal. If the RSRP of the first signal is less than or not greater than (in this article, it can be used interchangeably with less than or equal to) T4 and / or the RSRQ of the first signal is less than or not greater than T5, or if the Srxlev calculated based on the RSRP of the first signal is less than or not greater than T6 and / or the Squal calculated based on the RSRQ of the first signal is less than or not greater than T7, the UE performs RRM measurement based on the SSB. At this time, the RRM measurement based on the first signal is inaccurate because the UE is at the edge of the cell and the coverage of the first signal is insufficient. Therefore, an SSB with a larger coverage is used to perform RRM measurement;

[0183] o within a preconfigured or predefined time unit, when a variation range of one and / or multiple RSRPs of the first signal is less than or equal to T8 and / or a variation range of one and / or multiple RSRQs of the first signal is less than or equal to T9, or a variation range of Srxlev calculated based on the RSRP of the first signal is less than or equal to T10 and / or a variation range of Squal calculated based on the RSRQ of the first signal is less than or equal to T11, the UE performs RRM measurement based on the first signal;

[0184] o When the RSRP of the SSB is greater than or not less than T12 and / or the RSRQ of the SSB is greater than or not less than T13, or when Srxlev calculated based on the RSRP of the SSB is greater than or not less than T14 and / or Squal calculated based on the RSRQ of the SSB is greater than or not less than T15, the UE may perform RRM measurement based on the first signal. Otherwise, the UE performs RRM measurement based on the SSB;

[0185] o Within a preconfigured or predefined time unit, when the variation range of the RSRP of the SSB is less than or equal to T16 and / or the variation range of the RSRQ of the SSB is less than or equal to T17, or when the variation range of Srxlev calculated based on the RSRP of the SSB is less than or equal to T18 and / or Squal calculated based on the RSRQ of the SSB is less than or equal to T19, the UE may perform RRM measurement based on the first signal. Otherwise, the UE performs RRM measurement based on the SSB;

[0186] oT1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, T16, T17, T18, and T19 are predefined or (pre) configured threshold values, all of which are real numbers.

[0187] The condition for the UE to perform RRM measurement based on SSB may include a combination of one or more of the following: o If the first signal is not received for more than D time units, then after D time units, the UE performs RRM measurement based on SSB. Wherein, D is a parameter value predefined or (pre) configured by the base station, and D is a real number greater than 0. Optionally, the failure to receive the first signal for more than D time units is due to the first signal being discarded or delayed in transmission within the D time units.

[0188] o If the variation range or difference between the RSRP of the first signal of the neighboring cell and the RSRP of the first signal of the serving cell is greater than or not less than T20 and / or the variation range or difference between the RSRQ of the first signal of the neighboring cell and the RSRQ of the first signal of the serving cell is greater than or not less than T21, or the variation range of Srxlev calculated based on the RSRP of the first signal is greater than or not less than T22 and / or the Squal calculated based on the RSRQ of the first signal is greater than or not less than T23, the UE performs RRM measurement based on SSB or the UE performs cell selection and / or cell reselection. Since the UE cannot determine whether the large difference between the RRM measurement results of the neighboring cell and the serving cell is due to the inaccurate measurement results based on the first signal or the limited coverage of the first signal, the UE wakes up and uses SSB to perform RRM measurement.

[0189] o If the UE is unable to monitor the first signal, such as during cell reselection, the UE wakes up and uses SSB to perform RRM measurements. Optionally, if the UE is unable to monitor the first signal, such as during cell reselection, the UE wakes up and uses SSB to perform RRM measurements until the start of the next first signal (e.g., LP-SS or LP-SS burst) or until the end of the PTW, whichever is earlier.

[0190] oThe T20, T21, T22, and T23 are predefined or (pre) configured threshold values, all of which are real numbers.

[0191] The conditions for the UE to perform cell selection and / or cell reselection may include a combination of one or more of the following: o If the RRM measurement result based on the first signal meets the cell reselection principle, that is, the RSRP of the first signal is less than or not greater than the first threshold and / or the RSRQ is less than or not greater than the second threshold, or the Srxlev calculated based on the RSRP of the first signal is less than or not greater than the first threshold and / or the Squal calculated based on the RSRQ of the first signal is less than or not greater than the second threshold, the UE performs cell selection and / or cell reselection. Otherwise, the UE performs RRM measurement of the serving cell and / or neighboring cell based on the first signal, such as Figure 8 (a). The UE performing RRM measurement of the serving cell and the neighboring cell based on the first signal is applicable to the case where the first signal and the SSB have the same coverage. The UE performing RRM measurement of the serving cell based on the first signal is applicable to the case where the first signal and the SSB have the same coverage and the UE capability does not support RRM measurement of the neighboring cell based on the first signal. o If there is a non-serving cell within a predefined or preconfigured duration, the RSRP based on the first signal is greater than or not less than the third threshold and / or the RSRQ is greater than or not less than the fourth threshold, or the Srxlev calculated based on the RSRP of the first signal is greater than or not less than the third threshold and / or the Squal calculated based on the RSRQ of the first signal is greater than or not less than the fourth threshold, the UE can temporarily camp on the current cell, such as Figure 8 (a). If there are multiple cells whose RSRP based on the first signal is greater than or not less than the third threshold and / or whose RSRQ is greater than or not less than the fourth threshold within a predefined or preconfigured duration, or whose Srxlev calculated based on the RSRP of the first signal is greater than or not less than the third threshold and / or whose Squal calculated based on the RSRQ of the first signal is greater than or not less than the fourth threshold, the UE selects the cell on the highest priority frequency.

[0192] o If the RRM measurement result based on SSB meets the cell reselection principle, that is, the RSRP of SSB

[0193] is less than or not greater than the seventh threshold and / or the RSRQ is less than or not greater than the eighth threshold, or the Srxlev calculated based on the RSRP of the SSB is less than or not greater than the seventh threshold and / or the Squal calculated based on the RSRQ of the SSB is less than or not greater than the eighth threshold, the UE performs cell selection and / or cell reselection, such as Figure 8 (b) as shown.

[0194] o If there is a non-serving cell for which the RSRP based on the SSB is greater than or not less than the fifth threshold and / or the RSRQ is greater than or not less than the sixth threshold within a predefined or preconfigured duration, or the Srxlev calculated based on the RSRP of the SSB is greater than or not less than the fifth threshold and / or the Squal calculated based on the RSRQ of the SSB is greater than or not less than the sixth threshold, the UE may camp on the current cell, such as Figure 8 (b) If there are multiple cells whose RSRP based on SSB is greater than or not less than the fifth threshold and / or RSRQ is greater than or not less than the sixth threshold within a predefined or preconfigured duration, or Srxlev calculated based on RSRP of SSB is greater than or not less than the fifth threshold and / or Squal calculated based on RSRQ of SSB is greater than or not less than the sixth threshold, the UE selects the cell on the highest priority frequency.

[0195] oOptional, such as Figure 8 As shown in (c), the UE can determine whether the cell reselection principle is met based on the SSB, and / or determine whether it can temporarily stay in a cell based on the first signal.

[0196] oOptional, such as Figure 8 As shown in (d), the UE may determine whether the cell reselection principle is met based on the first signal, and / or determine whether it can temporarily reside in a cell based on the SSB. o When the first condition is not met and / or if the RRM measurement result based on the SSB does not meet the cell reselection principle, that is, the RSRP of the SSB is greater than or not less than the seventh threshold and / or the RSRQ is greater than or not less than the eighth threshold, or the Srxlev calculated based on the RSRP of the SSB is greater than or not less than the seventh threshold and / or the Squal calculated based on the RSRQ of the SSB is greater than or not less than the eighth threshold, the UE performs RRM measurement of the serving cell and the non-serving cell based on the SSB.

[0197] oWhen the first condition is met and / or if the RRM measurement result based on SSB does not meet the cell reselection principle, that is, the RSRP of the SSB is greater than or not less than the seventh threshold and / or the RSRQ is greater than or not less than the eighth threshold, or the Srxlev calculated based on the RSRP of the SSB is greater than or not less than the seventh threshold and / or the Squal calculated based on the RSRQ of the SSB is greater than or not less than the eighth threshold, the UE does not perform RRM measurement of non-serving cells.

[0198] o Optionally, the seventh threshold may be equal to the first threshold, and the eighth threshold may be equal to the second threshold;

[0199] o Optionally, the fifth threshold may be equal to the third threshold, and the sixth threshold may be equal to the fourth threshold;

[0200] oThe first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold, the seventh threshold, and the eighth threshold are preconfigured or predefined thresholds, and are all real numbers.
