[0003] The introduction of a low-power wake-up signal (LP-WUS) allows a terminal to turn off or put its main communication module into a sleep state, effectively reducing terminal power consumption. The low-power wake-up signal can be modulated using amplitude shift keying (ASK), allowing the wake-up module to detect the wake-up signal using envelope detection, thereby reducing power consumption to the microwatt level. When the low-power wake-up signal is introduced into a communication system, it can save power consumption whether the terminal is in a Radio Resource Control (RRC) idle or inactive state or an RRC connected state. In addition, in mobile cellular systems, a low-power beacon signal is introduced for the Low Power Wake Up Receiver (LP-WUR) / LP-WUS to maintain coarse synchronization with the network, monitor channel conditions, and determine whether the terminal itself is still within service range, thereby supporting a certain degree of terminal mobility.

[0020] In order to better understand the technical solutions provided in the embodiments of the present application, the following will explain and describe relevant concepts that may be involved in the embodiments of the present application.

[0021] NR Low power wake-up receiver / wake-up signal (LP WUR / WUS) The basic operating principle of LP WUR is that the receiving end (e.g., user equipment (UE)) includes a first module and a second module. The first module is a main communication module used for receiving communication data transmitted by the transmitting end and transmitting communication data. The second module is a low-power module used for receiving a low-power wake-up signal transmitted by the transmitting end and waking up the main communication module of the receiving end. As shown in FIG. 2a, when the first module is not awakened by the second module, it is always in an off state and does not receive data. When downlink data arrives and the second module detects the wake-up signal transmitted by the transmitting end, and the wake-up signal contains the terminal's identification information, the second module triggers the first module to switch from an off state to an on state and transmit or receive data. The second module can be continuously or intermittently on, and when the second module is on, it can receive a low-power wake-up signal.

[0022] Bandwidth Part (BWP) / Initial Bandwidth Part (Initial BWP) NR can support a wide bandwidth of up to 400 MHz. However, to reduce terminal power consumption and flexibly realize different service application scenarios, NR introduces BWPs, allowing terminals to operate at different BWPs. For example, referring to Figure 2b, at time T1, the terminal operates at BWP1; at time T2, the terminal operates at BWP2; at time T3, the terminal operates at BWP3; at time T4, the terminal operates at BWP2 again; and at time T5, the terminal operates at BWP1. The bandwidths of these BWPs may be different, and the subcarrier spacing may also be different. More importantly, the operating frequencies of the radio frequency centers may also be different. In Figure 2b, the radio frequency centers of BWP1 and BWP2 are the same, which means that the operating frequency of the terminal's radio frequency device does not need to be switched. However, the operating center frequency of BWP3 changes, which means that when the terminal switches from BWP2 to BWP3, the operating frequency of the radio frequency device needs to be changed. The advantage of this is that the radio frequency device does not need to operate with a wide bandwidth (in FIG. 2b, without frequency switching, the radio frequency device needs to support a bandwidth of BWP1+BWP3).

[0023] The initial uplink (UL) BWP and initial downlink (DL) BWP, i.e., the initial DL BWP and initial UL BWP, are configured in the System Information Block (SIB) 1. If the initial BWP is not configured, the default size of the initial BWP is the size of the Control Resource Set (CORESET) #0. The initial BWP is mainly used for the initial access process, such as receiving SIB 1, receiving a Random Access Response (RAR) during the random access process, receiving a Message (Msg) 4, and transmitting a preamble and Msg 3.

[0024] UE side flow of cell search / initial access process: 1. Receive a synchronization signal block (SSB) and a master information block (MIB) carried on the physical broadcast channel (PBCH) in the SSB, and obtain CORESET#0 information. 2. CORESET#0 intercepts the Downlink Control Information (DCI) of SIB1. 3. Decode SIB1 to obtain the initial DL / UL BWP and CORESET of the RAR or msg4 DCI.

[0025] The search space (SS) defines information such as a physical downlink control channel (PDCCH), an orthogonal frequency division multiplex (OFDM) symbol number, and a PDCCH monitoring period.

[0026] As shown in Table 1 below, in NR, the PDCCH has multiple search spaces, including a common search space (CSS) and a user equipment-specific search space (USS).

[0028] Hereinafter, with reference to the drawings, a signal receiving method provided in the embodiments of the present application according to some embodiments and its application scenarios will be described in detail.

[0029] FIG. 3 is a flowchart of a signal receiving method provided in an embodiment of the present application, as shown in FIG. 3, the method includes the following steps:

[0030] Step 301: A terminal determines a target frequency domain parameter for receiving a low-power associated signal according to a first frequency domain parameter or a second frequency domain parameter.

[0031] The target frequency domain parameters include at least one of a target center frequency point, a target bandwidth, and a target frequency domain start / end position, the first frequency domain parameters are frequency domain parameters of a first cell in which the terminal is located, and the second frequency domain parameters are frequency domain parameters defined by a protocol or set by a network side, and the target frequency domain start / end position includes at least one of a target frequency domain start position and a target frequency domain end position.

[0032] It should be noted that the low-power-related signal may refer to a signal related to the implementation of a low-power function of the terminal, and may include, for example, a low-power wake-up signal and a low-power beacon signal. For example, taking a low-power wake-up signal (LP-WUS) as an example, the terminal determines target frequency domain parameters for receiving the LP-WUS, such as a target center frequency point or a target frequency domain start / end position, and further, the terminal may receive the low-power wake-up signal based on the determined target center frequency point or target frequency domain start / end position.

[0033] In some embodiments, the low-power beacon signal may be referred to as a low-power activation signal. The low-power beacon signal can be used to maintain coarse synchronization between the terminal and the network, monitor channel conditions, determine whether the terminal itself is still within the service range, and support the mobility of the terminal. To better explain the technical solutions of the embodiments of the present application, some specific embodiments in the following embodiments will be described using a low-power wake-up signal as an example, and these embodiments will also apply to the low-power beacon signal.

[0034] In the embodiment of the present application, the target frequency domain parameter is taken as an example to be a target central frequency point, and the target central frequency point may be determined based on the frequency domain parameter of a first cell, for example, the target central frequency point of the low power related signal may be determined based on the frequency point of the first cell where the main communication module of the terminal is located, or the target central frequency point of the low power related signal may be determined based on the central frequency point of the low power related signal defined by a protocol or set by a network side.

[0035] For example, taking a low-power wake-up signal as an example, if a specific center frequency point of the low-power wake-up signal is defined by a protocol or set by a network side, the terminal can determine the center frequency point as the target center frequency point of the low-power wake-up signal. That is, the terminal can receive the low-power wake-up signal based on the center frequency point. It should be noted that the specific center frequency point of the low-power wake-up signal defined by a protocol or set by a network side may be different from the operating frequency point of the main communication module.

[0036] Alternatively, the terminal may determine the target central frequency point based on the frequency point of the first cell in which the main communication module is located. For example, the target central frequency point of the low power wake-up signal may be determined based on the center frequency point of the current serving cell in which the main communication module of the terminal is located, for example, the center frequency point of the current serving cell in which the main communication module is located is set as the target central frequency point of the low power wake-up signal. Alternatively, the target central frequency point of the low power wake-up signal may be determined based on the center frequency point of the current serving cell in which the main communication module is located and a target frequency offset. Note that possible situations of the first cell and the frequency point of the first cell will be described in subsequent embodiments and will not be specifically described here.

[0037] Alternatively, the terminal may determine the target center frequency point of the low power wakeup signal based on the frequency domain resource of the low power wakeup signal. For example, the frequency domain resource of the low power wakeup signal includes a frequency domain start position and a bandwidth, and the terminal can determine the target center frequency point of the low power wakeup signal based on the frequency domain start position and the bandwidth of the low power wakeup signal. For example, the target center frequency point f0=f_start+(f_bw / 2), where f_start is the frequency domain start position and f_bw is the bandwidth. Of course, the frequency domain resource may be in other possible situations, and the determination of the target center frequency point based on the frequency domain resource of the low power wakeup signal may also be in other possible situations, which will not be specifically described herein.

[0038] In an embodiment of the present application, the terminal may determine the target central frequency point of the low power-related signal based on the frequency point of the first cell in which the terminal is located and / or the frequency point defined by a protocol or set by a network side and / or the frequency domain resource of the low power-related signal, thereby making the manner in which the terminal determines the target central frequency point of the low power-related signal more flexible and diverse.

[0039] In an embodiment of the present application, the target frequency domain parameters of the low power related signal may include a target bandwidth and / or a target frequency domain start position and / or a target frequency domain end position, that is, the terminal may determine at least one of the target bandwidth, the target frequency domain start position and the target frequency domain end position of the low power related signal based on the first frequency domain parameter or the second frequency domain parameter.

[0040] For example, taking a low-power wake-up signal as an example, the terminal may determine a frequency domain resource of the low-power wake-up signal based on a target center frequency point of the low-power wake-up signal. For example, the terminal may determine the bandwidth of the low-power wake-up signal based on the target center frequency point of the low-power wake-up signal. Alternatively, the terminal may determine a frequency domain start position of the low-power wake-up signal based on the low-power wake-up signal and a predetermined bandwidth. For example, the frequency domain start position f_start=f0-(f_bw / 2), where f0 is the target center frequency point of the low-power wake-up signal and f_bw is the bandwidth of the low-power wake-up signal.

[0041] In an embodiment of the present application, the terminal may determine at least one of a target bandwidth, a target frequency domain start position, and a target frequency domain end position of the low-power related signal based on the first frequency domain parameter or the second frequency domain parameter, thereby making the manner of determining the frequency domain resource of the low-power related signal by the terminal more flexible and diverse.

[0042] Step 302: The terminal receives the low-power-associated signal according to a frequency domain resource corresponding to the target frequency domain parameter.

[0043] For example, taking a low-power wake-up signal as an example, after the UE determines at least one of a target center frequency point, a target bandwidth, and a target frequency domain start / end position of the low-power wake-up signal, the UE can receive the low-power wake-up signal based on at least one of the determined target center frequency point, the target bandwidth, and the target frequency domain start / end position. For example, if the frequency domain resource includes a frequency domain start position, the UE can start receiving the low-power wake-up signal at the determined frequency domain start position or receive the low-power wake-up signal near the determined target center frequency point. Not many examples will be given here.

[0044] In an embodiment of the present application, the terminal can determine target frequency domain parameters of the low power related signal based on a first frequency domain parameter of a first cell in which the terminal is located or a second frequency domain parameter defined by a protocol or set by a network side. Furthermore, the terminal can perform reception of the low power related signal based on the determined target frequency domain parameter. In this way, the frequency domain parameters for the terminal to receive the low power related signal are clear, ensuring that the terminal can receive the low power related signal, and ensuring communication of the terminal.

[0045] In an embodiment of the present application, when the target frequency domain parameters include a target center frequency point, the first frequency domain parameters are: a center frequency point of the first cell; a center frequency point of a cell-defining synchronization signal block (Cell Defining SSB, CD-SSB) of the first cell; a center frequency point of a non-cell-defining synchronization signal block (NCD-SSB) of the first cell; a frequency point of a common reference point of the first cell; and a center frequency point of the first BWP of the first cell.

[0046] Optionally, the first cell includes at least one of a serving cell, a primary cell (Pcell), and a secondary cell (Scell). If the first cell includes a serving cell, the serving cell may include a primary cell (e.g., a Pcell, a primary secondary cell (PScell)) and a secondary cell. If the first cell includes a primary cell, the primary cell includes only a Pcell or a PScell.

[0047] For example, when the first cell is a serving cell of the terminal, the terminal may determine the target center frequency point of the low power related signal based on the center frequency point of the serving cell. For example, the terminal may set the center frequency point of the serving cell as the target center frequency point of the low power related signal, or may set the sum or difference of the center frequency point of the serving cell and a predetermined frequency offset as the target center frequency point of the low power related signal.

[0048] Of course, the first cell may be a primary cell or a secondary cell, and the frequency point of the first cell may be in other possible forms as mentioned above, which will not be listed one by one here.

[0049] Optionally, the step of determining a target frequency domain parameter for receiving a low power associated signal by the terminal according to the first frequency domain parameter further comprises: When the first frequency domain parameter includes a center frequency point of the first cell, a step of acquiring a first frequency offset by the terminal, and determining a target center frequency point at which the terminal receives a low power related signal based on the first frequency offset and the center frequency point of the first cell, wherein the first frequency offset is a frequency offset of the target center frequency point of the low power related signal relative to the center frequency point of the first cell, the frequency offset being specified by a protocol or set by a network side; When the first frequency domain parameter includes a center frequency point of CD-SSB of the first cell, a terminal acquires a second frequency offset, and determines a target center frequency point at which the terminal receives a low-power associated signal based on the second frequency offset and the center frequency point of CD-SSB, where the second frequency offset is a frequency offset of the target center frequency point of the low-power associated signal relative to the center frequency point of CD-SSB, the frequency offset being specified by a protocol or set by a network side; If the first frequency domain parameter includes a center frequency point of NCD-SSB of the first cell, a terminal acquires a third frequency offset, and determines a target center frequency point at which the terminal receives a low power associated signal based on the third frequency offset and the center frequency point of NCD-SSB, where the third frequency offset is a frequency offset of the target center frequency point of the low power associated signal relative to the center frequency point of the NCD-SSB, the frequency offset being specified by a protocol or set by a network side; When the first frequency domain parameters include a frequency point of a common reference point of the first cell, a terminal acquires a fourth frequency offset, and determines a target central frequency point at which the terminal receives a low power associated signal based on the fourth frequency offset and the frequency point of the common reference point, wherein the fourth frequency offset is a frequency offset of the target central frequency point of the low power associated signal relative to the frequency point of the common reference point, the frequency offset being specified by a protocol or set by a network side; and if the first frequency domain parameter includes a center frequency point of a first BWP of the first cell, a step of acquiring a fifth frequency offset by the terminal, and determining a target center frequency point at which the terminal receives a low power related signal based on the fifth frequency offset and the center frequency point of the first BWP, wherein the fifth frequency offset is a frequency offset of the target center frequency point of the low power related signal relative to the center frequency point of the first BWP, which is specified by a protocol or set by a network side.

[0050] For example, in one embodiment, if the first frequency domain parameters include a center frequency point f1 of the first cell, and a first frequency offset offset1 of the target center frequency point f0 of the low power related signal relative to the center frequency point f1 of the first cell is specified by a protocol or set by the network side, the terminal can determine the target center frequency point f0 of the low power related signal based on the above f1 and offset1, for example, f0=f1-offset1 or f0=f1+offset1.

[0051] In another embodiment, when the first frequency domain parameters include the center frequency point f2 of the CD-SSB of the first cell, and a second frequency offset offset2 of the target center frequency point f0 of the low-power related signal relative to the center frequency point f2 of the CD-SSB of the first cell is specified by a protocol or set by the network side, the terminal can determine the target center frequency point f0 of the low-power related signal based on the above f2 and offset2, for example, f0=f2-offset2 or f0=f2+offset2.

[0052] In yet another embodiment, when the first frequency domain parameters include a center frequency point f3 of the NCD-SSB of the first cell, and a third frequency offset offset3 of the target center frequency point f0 of the low-power related signal relative to the center frequency point f3 of the NCD-SSB of the first cell is specified by a protocol or set by the network side, the terminal can determine the target center frequency point f0 of the low-power related signal based on the above f3 and offset3, for example, f0=f3-offset3 or f0=f3+offset3.

[0053] In yet another embodiment, when the first frequency domain parameters include a frequency point f4 of a common reference point (Point A) of the first cell, and a fourth frequency offset offset4 of the target center frequency point f0 of the low power related signal relative to the frequency point f4 of the common reference point of the first cell is specified by a protocol or set by the network side, the terminal can determine the target center frequency point f0 of the low power related signal based on the above f4 and offset4, for example, f0=f4-offset4 or f0=f4+offset4.

[0054] In yet another embodiment, when the first frequency domain parameters include a center frequency point f5 of the first BWP of the first cell, and a fifth frequency offset offset5 of the target center frequency point f0 of the low power related signal relative to the center frequency point f5 of the first BWP of the first cell is specified by a protocol or set by the network side, the terminal can determine the target center frequency point f0 of the low power related signal based on the above f5 and offset5, for example, f0=f5-offset5 or f0=f5+offset5.

[0055] Optionally, the first BWP includes at least one of a currently active BWP (which may also be referred to as an active BWP, or an activated BWP), a default BWP, an initial downlink BWP (e.g., BWP#0), and a first active downlink BWP.

[0056] Optionally, the first BWP is defined by a protocol or configured by a network side, and the first BWP comprises: The first BWP is used to transmit only low-power related signals; The first BWP satisfies any one of the following conditions: the first BWP is used to transmit a low-power related signal and other data and signals other than the low-power related signal.

[0057] For example, the first BWP specified by the protocol or configured by the network side may be a specific BWP for low power related signals, i.e., the BWP is used to transmit only low power related signals (e.g., LP-WUS), and the BWP may not be counted as an RRC-configured BWP, and the BWP for the low power related signals does not occupy the allocation of up to one or four RRC-configured BWPs that the UE can support.

[0058] Alternatively, the first BWP specified by the protocol or configured by the network side may be a BWP multiplexed with other data or signals, and the BWP will be counted as an RRC-configured BWP, and the BWP will occupy the allocation of up to one or four RRC-configured BWPs that the UE can support.

[0059] In an embodiment of the present application, when the target frequency domain parameters include a target frequency domain start position, the first frequency domain parameters are: a frequency domain start position of the first cell; a frequency domain starting position of a first BWP of the first cell; a frequency point of a common reference point of the first cell; The frequency domain starting position of the first cell may include at least one of a CD-SSB frequency domain starting position or an NCD-SSB frequency domain starting position of the first cell.

[0060] Optionally, an absolute frequency domain position of the low power associated signal may be specified by a protocol or set by the network side, and the terminal may take the absolute frequency domain position as the frequency domain starting position of the low power associated signal.

[0061] Alternatively, the frequency domain start position of the low power-related signal may be determined based on a center frequency point of the low power-related signal defined by a protocol or set by a network side. For example, the center frequency point of the low power-related signal defined by a protocol or set by a network side is f0, and the frequency domain start position of the low power-related signal is f_start=f0-(f_bw / 2), where f_bw is the bandwidth occupied by the low power-related signal.

[0062] In an embodiment of the present application, the frequency domain start position of the low power related signal may be determined based on the frequency domain start position of the first cell in which the main communication module is located, and / or may be determined based on the frequency domain start position of the first BWP of the first cell, the frequency point of the common reference point, the frequency domain start position of CD-SSB, and the frequency domain start position of NCD-SSB.

[0063] Alternatively, the frequency domain start position of the low power related signal may be determined based on a center frequency point of the low power related signal specified by a protocol or set by the network side, and a frequency domain offset of the frequency point of the frequency domain start position of the low power related signal relative to this frequency point.

[0064] Optionally, the step of determining a target frequency domain parameter for receiving a low power associated signal by the terminal according to a second frequency domain parameter further comprises: determining a target center frequency point for the terminal to receive a low-power related signal according to a center frequency point defined by a protocol or set by a network side; and determining a frequency domain start position for receiving a low-power associated signal by the terminal according to a center frequency point and a first frequency offset defined by a protocol or set by a network side.

[0065] For example, if the center frequency point f0 of the low-power-related signal is defined by a protocol or set by the network side, the terminal determines the center frequency point f0 as the target center frequency point for receiving the low-power-related signal.

[0066] Alternatively, if a first frequency domain offset offset_bw1 of the frequency domain start position f_start of the low power related signal relative to the center frequency point f0 is specified by a protocol or set by the network side, the terminal can determine the frequency domain start position f_start of the low power related signal based on the center frequency point f0 and the first frequency domain offset offset_bw1, for example, f_start=f0'-offset_bw1 or f_start=f0'+offset_bw1.

[0067] Alternatively, the terminal may determine the frequency domain starting position of the low power associated signal based on the frequency domain parameters of the first cell.

[0068] Optionally, the target frequency domain parameters include a target frequency domain start position, and the step of determining the target frequency domain parameters for receiving a low power associated signal by the terminal according to the first frequency domain parameters includes: a step of the terminal acquiring a second frequency domain offset and a frequency domain start position of a first cell, and determining a target frequency domain start position of the low power related signal based on the second frequency domain offset and the frequency domain start position of the first cell, wherein the second frequency domain offset is a frequency domain offset of the target frequency domain start position of the low power related signal relative to the frequency domain start position of the first cell, the frequency domain offset being specified by a protocol or set by a network side; a step in which the terminal acquires a third frequency domain offset and a frequency domain start position of a first BWP of a first cell, and determines a target frequency domain start position of the low power associated signal based on the third frequency domain offset and the frequency domain start position of the first BWP, wherein the third frequency domain offset is a frequency domain offset of the target frequency domain start position of the low power associated signal relative to the frequency domain start position of the first BWP, the frequency domain offset being specified by a protocol or set by a network side; the terminal acquiring a fourth frequency domain offset and a frequency domain start position of a common reference point of a first cell, and determining a target frequency domain start position of the low power associated signal based on the fourth frequency domain offset and the frequency domain start position of the common reference point, wherein the fourth frequency domain offset is a frequency domain offset of the target frequency domain start position of the low power associated signal relative to the frequency domain start position of the common reference point, the frequency domain offset being specified by a protocol or set by a network side; a step in which the terminal acquires a fifth frequency domain offset and a frequency domain start position of CD-SSB of the first cell, and determines a target frequency domain start position of the low power associated signal based on the fifth frequency domain offset and the frequency domain start position of the CD-SSB, wherein the fifth frequency domain offset is a frequency domain offset of the target frequency domain start position of the low power associated signal relative to the frequency domain start position of the CD-SSB, the frequency domain offset being specified by a protocol or set by a network side; and a step of the terminal acquiring a sixth frequency domain offset and a frequency domain start position of an NCD-SSB of the first cell, and determining a target frequency domain start position of the low power related signal based on the sixth frequency domain offset and the frequency domain start position of the NCD-SSB, wherein the sixth frequency domain offset is a frequency domain offset of the target frequency domain start position of the low power related signal relative to the frequency domain start position of the NCD-SSB, which is specified by a protocol or set by a network side.

[0069] For example, in one embodiment, if a second frequency domain offset offset_bw2 of the target frequency domain start position f_start of the low power related signal relative to the frequency domain start position f_cell of the first cell is specified by a protocol or set by the network side, the terminal can determine the target frequency domain start position f_start of the low power related signal based on the frequency domain start position f_cell of the first cell and the second frequency domain offset offset_bw2, for example, f_start=f_cell-offset_bw2 or f_start=f_cell+offset_bw2.

[0070] In another embodiment, when a third frequency domain offset offset_bw3 of the target frequency domain start position f_start of the low power related signal relative to the frequency domain start position RB0 of the first BWP of the first cell is specified by a protocol or set by the network side, the terminal can determine the target frequency domain start position f_start of the low power related signal based on the frequency domain start position RB0 of the first BWP and the third frequency domain offset offset_bw3, for example, f_start=RB0-offset_bw3 or f_start=RB0+offset_bw3.

[0071] In yet another embodiment, when a fourth frequency domain offset offset_bw4 of the target frequency domain start position f_start of the low power related signal relative to the frequency domain start position f_point of the common reference point of the first cell is specified by a protocol or set by the network side, the terminal can determine the target frequency domain start position f_start of the low power related signal based on the frequency domain start position f_point of the common reference point and the fourth frequency domain offset offset_bw4, for example, f_start=f_point-offset_bw4 or f_start=f_point+offset_bw4.

[0072] In yet another embodiment, when a fifth frequency domain offset offset_bw5 of the target frequency domain start position f_start of the low power related signal relative to the frequency domain start position fs1 of the CD-SSB of the first cell is specified by a protocol or set by the network side, the terminal can determine the target frequency domain start position f_start of the low power related signal based on the frequency domain start position fs1 of the CD-SSB and the fifth frequency domain offset offset_bw5, for example, f_start=fs1-offset_bw5 or f_start=fs1+offset_bw5.

[0073] In yet another embodiment, when a sixth frequency domain offset offset_bw6 of the target frequency domain start position f_start of the low power related signal relative to the frequency domain start position fs2 of the NCD-SSB of the first cell is specified by a protocol or set by the network side, the terminal can determine the target frequency domain start position f_start of the low power related signal based on the frequency domain start position fs2 of the NCD-SSB and the sixth frequency domain offset offset_bw6, for example, f_start=fs2-offset_bw6 or f_start=fs2+offset_bw6.

[0074] In an embodiment of the present application, the terminal can determine the frequency domain starting position of the low power related signal according to the frequency domain starting position of the related parameters of the first cell, thereby making the manner of determining the frequency domain starting position of the low power related signal by the terminal more flexible.Optionally, if the target parameters of the low power related signal determined by the terminal include frequency domain resources of the low power related signal, before the terminal determines the target parameters for receiving the low power related signal, or after the terminal determines the frequency domain starting position of the low power wake-up signal, the method can include: The method may further include determining a target bandwidth at which the terminal receives low-power-related signals.

[0075] Optionally, when the target frequency domain parameters include a target bandwidth, the terminal determines a target bandwidth for receiving low power related signals according to at least one of a setting by a network side, a capability of the terminal, and a protocol specification.

[0076] A target bandwidth for receiving low-power-related signals is set by the network side. For example, the BWP set by the network side is 20M, of which 5M is set for low-power-related signals. Optionally, the target bandwidth set by the network side may be equal to or greater than the bandwidth that the terminal needs to occupy when actually transmitting low-power-related signals.

[0077] Alternatively, the terminal may determine a target bandwidth at which the terminal receives the low-power-related signal based on its capability. The capability of the terminal may refer to the receiving capability or transmitting capability of the terminal. Alternatively, the value of the target bandwidth at which the terminal receives the low-power-related signal may be specified by a protocol.

[0078] In an embodiment of the present application, the low-power related signals include the low-power wake-up signal and a low-power beacon signal, and the method includes: The method may further include the terminal determining a target frequency domain parameter of the second signal based on the target frequency domain parameter of the first signal; The first signal is one of the low power wake-up signal and the low power beacon signal, and the second signal is the other of the low power wake-up signal and the low power beacon signal.

[0079] For example, the first signal is a low-power wake-up signal, and the second signal is a low-power beacon signal. Furthermore, the terminal can determine target frequency-domain parameters of the low-power beacon signal based on the target frequency-domain parameters of the low-power wake-up signal. Exemplarily, the terminal determines a target center frequency point f0' of the low-power beacon signal based on the target center frequency point f0 of the low-power wake-up signal, e.g., f0'=f0. Alternatively, the terminal determines a frequency-domain start position f_start' of the low-power beacon signal based on the frequency-domain start position f_start of the low-power wake-up signal, e.g., f_start'=f_start.

[0080] Optionally, the step of the terminal determining the target frequency domain parameters of the second signal based on the target frequency domain parameters of the first signal comprises: When the target frequency domain parameters include a target center frequency point, the terminal determines the target center frequency point of the first signal as the target center frequency point of the second signal, or determines the target center frequency point of the second signal based on the target center frequency point of the first signal and a predetermined frequency offset; If the target frequency domain parameters include a target frequency domain resource, the terminal determines the target frequency domain resource of the first signal as the target frequency domain resource of the second signal, or determines the target frequency domain resource of the second signal based on at least one of the target frequency domain resource of the first signal and a predetermined frequency domain offset, wherein the target frequency domain resource includes at least one of a target bandwidth and a target frequency domain start / end position.

[0081] For example, if the target parameters include a target center frequency point, the first signal is a low-power wake-up signal, and the second signal is a low-power beacon signal, the terminal may determine the target center frequency point f0' of the low-power beacon signal based on the target center frequency point f0 of the low-power wake-up signal, for example, f0'=f0. Alternatively, the terminal may determine the target center frequency point f0' of the low-power beacon signal based on the target center frequency point f0 of the low-power wake-up signal and a predetermined frequency offset offset10, for example, f0'=f0+offset10 or f0'=f0-offset10.

[0082] When the target parameters include frequency domain resources, the first signal is a low-power wake-up signal, and the second signal is a low-power beacon signal, for example, the terminal may determine a frequency domain start position f_start' of the low-power beacon signal based on the frequency domain start position f_start of the low-power wake-up signal, e.g., f_start'=f_start. Alternatively, the terminal may determine a frequency domain start position f_start' of the low-power beacon signal based on the frequency domain start position f_start of the low-power wake-up signal and a predetermined frequency domain offset offset11, e.g., f_start'=f_start+offset11 or f_start'=f_start-offset11. Note that the frequency domain resources may also be a frequency domain end position, a bandwidth, etc. For example, the terminal may determine a frequency domain end position f_end' of the low-power beacon signal based on the frequency domain end position f_end of the low-power wake-up signal, e.g., f_end'=f_end. Alternatively, the terminal determines the bandwidth f_bw' occupied by the low-power beacon signal based on the bandwidth f_bw' occupied by the low-power wake-up signal, for example, f_bw'=f_bw. In this embodiment, not many examples are given.

[0083] Of course, the first signal may be a low-power beacon signal, and the second signal may be a low-power wake-up signal. In this case, the terminal may determine the target center frequency point of the low-power beacon signal based on the target center frequency point of the low-power beacon signal and / or determine the target frequency domain resource of the low-power beacon signal based on the target frequency domain resource of the low-power beacon signal, which is not specifically mentioned here. In this way, the terminal may more flexibly determine the target center frequency point and / or the target frequency domain resource of the low-power related signal, thereby ensuring the reception of the low-power related signal by the terminal.

[0084] In an embodiment of the present application, the method comprises: The terminal may further include performing a first operation on a second BWP after stopping monitoring for a low-power-related signal or after being woken up by the low-power-related signal; The first operation is Receiving and / or measuring SSB; monitoring a PDCCH transmitted in a first target CSS type, the first target CSS type including at least one of CSS type 0, CSS type 0A, CSS type 1, and CSS type 2; Monitoring a PDCCH transmitted in a second target CSS type including CSS type 3; monitoring a PDCCH transmitted by the USS; receiving a Physical Downlink Shared Channel (PDSCH); receiving and / or measuring a downlink Channel State Information Reference Signal (CSI-RS); Receiving and / or measuring a Tracking Reference Signal (TRS); transmitting a target channel including at least one of a Physical Random Access Channel (PRACH), a Physical Uplink Shared Channel (PUSCH), and a Physical Uplink Control Channel (PUCCH); and transmitting a Sounding Reference Signal (SRS).

[0085] For example, taking the low-power wake-up signal as an example, after the terminal monitors the low-power wake-up signal and then stops monitoring the low-power wake-up signal (for example, when the terminal is woken up by the low-power wake-up signal, or when degradation of the current channel link is detected, or when the terminal needs to transmit uplink data, signals), the terminal may start performing the above-mentioned first operation, such as receiving and / or measuring SSB, receiving and / or measuring CSI-RS, TRS, and transmitting PUSCH and / or PUCCH, in the second BWP, which are not specifically described here.

[0086] In an embodiment of the present application, the terminal may perform the first operation in the second BWP after stopping monitoring the low power-related signal or after being woken up by the low power-related signal. Furthermore, the actions of the terminal after stopping monitoring the low power-related signal or after being woken up by the low power-related signal are defined to clarify the relevant actions of the terminal.

[0087] The CSS type 0, CSS type 0A, CSS type 1, CSS type 2, and CSS type 3 are specifically shown in Table 2.

[0088] [Table 2] CSS Type Table TIFF0007804104000002.tif88164

[0089] It should be noted that the second BWP may be different from the first BWP.

[0090] Optionally, the second BWP comprises: The initial BWP (for example, BWP#0), Default BWP and a first Active Downlink BWP; Currently active BWP and and a target BWP that is specified by a protocol or set by a network side and that performs the first operation after the terminal is woken up by a low power related signal.

[0091] Optionally, the currently active BWP: a BWP through which the low power related signal is transmitted; and the BWP used before the terminal monitors the low power-related signal.

[0092] It should be noted that any terminal in an RRC connected state, an RRC idle state, or an RRC inactive state can determine the target center frequency point, the frequency domain starting position, and the first operation of the low power related signal according to the method provided in the embodiments of the present application.

[0093] In an embodiment of the present application, the method comprises: The terminal may further include performing a second operation in the serving cell when starting to monitor a low power related signal, the second operation including: storing configuration information and / or scheduling information of a third BWP, which is a BWP that performs uplink transmission or downlink reception before the terminal is in a radio resource control (RRC) connected state and monitors a low power related signal; switching to a fourth BWP and storing configuration and / or scheduling information for the fourth BWP; storing configuration and / or scheduling information of all BWPs configured for said terminal or assigned by the network; and excluding configuration information and / or scheduling information of other BWPs other than the third BWP and the fourth BWP configured for the terminal.

[0094] In an embodiment of the present application, a terminal in an RRC connected state performs uplink transmission or downlink reception in a third BWP of a serving cell before monitoring a low power related signal, and when the terminal starts monitoring a low power related signal, the terminal performs at least one of the above second operations in the serving cell.

[0095] For example, in one embodiment, when a terminal starts monitoring a low power related signal, the terminal stores configuration information and / or scheduling information of a third BWP to be applied before monitoring a low power related signal, and / or when the terminal starts monitoring a low power related signal, the terminal switches to a fourth BWP and stores configuration information and / or scheduling information of the fourth BWP.

[0096] Alternatively, in another embodiment, when the terminal starts monitoring low power related signals, the terminal may store configuration information and / or scheduling information of all BWPs configured for the terminal or specified by the network.

[0097] Alternatively, in yet another embodiment, when the terminal starts monitoring a low power related signal, it eliminates the configuration information and / or scheduling information of other BWPs configured for the terminal, except for the third BWP and the fourth BWP (if switched to the fourth BWP).

[0098] It should be noted that the storing may also be referred to as retaining, for example, retaining the configuration information and / or scheduling information of the third BWP. The storing of the configuration information and / or scheduling information of the BWP includes suspending (not excluding or not releasing) the transmission and reception of some semi-static configuration information, such as the configuration information of the CORESET and the search space set, including the data information stored in the semi-persistent scheduling (SPS) PDSCH, the configured grant PUSCH, the scheduling request (SR), and the hybrid automatic repeat request (HARQ) buffer.

[0099] In an embodiment of the present application, for a terminal in an RRC connected state, when the terminal starts to monitor low power related signals, the terminal performs the second operation in the serving cell, that is, determines whether to store the configuration information and / or scheduling information of the associated BWP after the terminal starts to monitor low power related signals, thereby ensuring the terminal's management of the configuration information and / or scheduling information of the BWP.

[0100] Optionally, the fourth BWP comprises: Initial BWP (initial BWP, BWP#0) and Default BWP and a first Active Downlink BWP; Dormant BWP and A BWP in which CSS type 0 and / or CSS type 1 and / or CSS type 2 is set, in the case where CSS type 0 and / or CSS type 1 and / or CSS type 2 is not set in the third BWP; and a BWP in which a PRACH is set when a PRACH is not set in the third BWP.

[0101] In addition, if the CSS of CSS type 0 and / or CSS type 1 and / or CSS type 2 is not set in the third BWP, when the terminal starts monitoring a low power related signal, it switches to a BWP or initial BWP in which a CSS of CSS type 0 and / or CSS type 1 and / or CSS type 2 is set, and such a BWP is the fourth BWP.

[0102] Alternatively, if the PRACH is not configured in the third BWP, when the terminal starts monitoring a low power related signal, it switches to a BWP in which the PRACH is configured or an initial BWP, and such a BWP is the fourth BWP.

[0103] Optionally, when the terminal is in an RRC connected state and carrier aggregation is configured for the terminal, when the terminal starts monitoring a low power related signal, controlling a state of a serving cell in which the terminal is located to a target state; The target state is a state before the terminal starts monitoring a low-power-related signal; an inactive state or a dormant state; The primary cell state is the state before the terminal starts monitoring low power related signals, and the secondary cell state is an inactive state or a dormant state.

[0104] In an embodiment of the present application, when carrier aggregation is configured for a terminal in an RRC connected state, the terminal can perform downlink reception and / or uplink transmission on multiple carriers / serving cells, and when the terminal starts monitoring low power related signals, the terminal can control the state of the serving cell in which it is located to at least one of the above.

[0105] For example, when the terminal starts monitoring for low power related signals, the state of the serving cell can be made to match the state of the serving cell before starting monitoring for low power related signals. 1) If the serving cell (or carrier) is in an active state before monitoring, the serving cell (or carrier) remains in an active state after starting monitoring for low power related signals. 2) If the serving cell (or carrier) is in a deactivated state before monitoring, the serving cell (or carrier) remains in a deactivated state after starting monitoring for low power related signals. 3) If the serving cell (or carrier) is dormant before monitoring, keep the serving cell (or carrier) dormant after starting monitoring for low power related signals.

[0106] Alternatively, regardless of the state of the serving cell before the terminal started monitoring the low power related signal, when the terminal starts monitoring the low power related signal, the state of the serving cell is controlled to a deactivated state or a dormant state.

[0107] Alternatively, the terminal may control the states of the primary cell and the secondary cell separately. When the terminal starts monitoring low power related signals, the terminal maintains the state of the primary cell (including only the PCell or including the PCell and the PSCell) as is, and controls the state of the secondary cell to a deactivated state or a dormant state. For example, if the primary cell is in an active state and the secondary cell is in an active state before monitoring, after starting monitoring low power related signals, the terminal keeps the primary cell in an active state and sets the secondary cell to a deactivated state or a dormant state.

[0108] In an embodiment of the present application, when a terminal in an RRC connected state starts monitoring low power related signals, it clarifies the state of the serving cell in which the terminal is located, and also clarifies the carrier state in which the terminal performs the corresponding operation (i.e., the above-mentioned second operation) in the corresponding BWP, thereby ensuring the communication of the terminal.
