It should be noted that only the base station in the NR system is taken as an example for description in the embodiments of the present application, and the specific type of the base station is not limited.
[0061] Before the embodiments of the present application are described, the related art is briefly introduced as follows:
[0062] I. Low-power receiver
[0063] In the related art, the 3rd Generation Partnership Project (3GPP) introduces the research work of low power wake up receiver (LP WUR) / low power wake up signal (LP WUS) in a mobile cellular system. The basic working principle of the LP WUR is that the receiving end (such as a terminal) includes a first module and a second module. As shown in FIG. 2, the first module is a main communication module (or a main receiver), which is used for transmitting and receiving mobile communication data. The second module is a low power wake up receiving module (or a low power receiving module, a low power receiver, etc.), which is used for receiving a wake up signal. The terminal opens the low power receiving module to listen to the LP-WUS and closes the main communication module in the energy saving state. When there is downlink data, the network node sends a wake up signal to the terminal. After the terminal listens to the wake up signal through the low power receiving module, the terminal triggers the main communication module from being closed to being opened through a series of judgments. At this time, the low power receiving module enters the closed state from the working state. The low power receiving module can be continuously opened or intermittently opened, and can receive the low power wake up signal when being opened.
[0064] The low power receiver can be divided into multiple types. For example, a first type of low power receiver has the ability to demodulate a first type of waveform and does not have the ability to demodulate a second type of waveform. For example, the first type of waveform is an On-Off Keying (OOK) signal, and the second type of waveform is an Orthogonal Frequency Division Multiplexing (OFDM) signal. A second type of low power receiver has the ability to detect the second type of waveform. This type of receiver can have the ability to demodulate the first type of waveform or does not have the ability to demodulate the first type of waveform.
[0065] The structure of low-power receiver can be divided into multiple types. For example, the receiver based on radio frequency envelope detection, or the receiver based on intermediate frequency envelope detection, or the receiver based on zero intermediate frequency baseband envelope detection. These low-power receiver structures are generally low in power consumption, and can be used at least for demodulation of on-off keying signals. And these low-power receiver structures can add a module for demodulating frequency shift keying (FSK) signals to support FSK signal demodulation. The low-power receiver structure supporting OFDM signal detection is different from the above three types of receiver structures at least in part of the modules, such as real and imaginary two-way signal processing. The signal processing can be sequence correlation processing. The low-power receiver of this structure is generally higher in power consumption than the above three types of receivers, but lower than the power consumption of the main receiver (MR).
[0066] II. Timing synchronization of different carriers in NR system
[0067] In the related art NR system, a UE in a connected state can be configured with multiple serving cells. In a multi-carrier aggregation (CA) scenario, the multiple serving cells belong to the same cell group and are served by the same gNB. In a dual connectivity (DC) scenario, the multiple serving cells belong to different cell groups, i.e., a master cell group (MCG) and a secondary cell group (SCG), and the terminal is served by two gNBs.
[0068] In the CA scenario, the system frame numbers (SFNs) of the multiple serving cells are aligned, and the slots can be aligned or not. The network node can indicate the UE with the slot offset parameters of the primary cell (Pcell) and one secondary cell (Scell).
[0069] In a DC scenario, the SFN of multiple serving cells can be misaligned, and the slots can also be misaligned. A network node can configure a connected UE to measure the observed SFN and SFN and frame timing difference (SFTD) of a Pcell and a primary secondary cell (Pscell) of a secondary cell group. Alternatively, even if not configured for DC, a network node can configure a connected UE to measure the SFTD of a Pcell and a neighbor cell. After measurement, the UE reports the SFTD result to the base station, which is used by the base station to coordinate the measurement gap and discontinuous reception (DRX) of the MCG and SCG.
[0070] That is, in the related art NR system, each cell time alignment or misalignment, same or different duplex mode, same or different subcarrier spacing (SCS) are supported, but all for the case of receiving all signals by the main receiver. For the case of LR and MR at different frequencies, whether each frequency is time-aligned, whether the duplex mode is the same, and whether the SCS is the same, and how it affects the configuration of the low-power signal and the reception of the low-power signal, have not been considered. Since LR and MR are different receivers, the signals that can be demodulated are different. When LR and MR are at different frequencies, the time of each frequency may not be aligned, the duplex mode may be different, and the SCS may be different. How the base station configures the low-power signal and how the terminal determines the time position of the occasion of the LP-WUS / low-power synchronization signal (Low Power Synchronization Signal) on the low-power receiver frequency point need to be proposed new solutions, otherwise the terminal may not be able to receive the low-power signal.
[0071] In view of this, the embodiments of the present application provide a signal receiving method, an information configuration method, a signal receiving device and a communication device to solve the problem that the terminal may not be able to receive the low-power signal in the related art.
[0072] The embodiments of the present application are applicable to various deployment scenarios.
[0073] In some deployment scenarios, the network node transmits the low power signal and other NR signals in the same frequency band / carrier / cell. In other deployment scenarios, the network node transmits the low power signal and other NR signals in different frequency bands / carriers / cells. The frequency band / carrier / cell in which the network node transmits the low power signal is a subset of the frequency band / carrier / cell in which the network node transmits other NR signals. For example, the network node transmits NR signals in the 2.6 GHz frequency band and transmits the LP-WUS / LP-SS in the 900 MHz frequency band. Or, the network node transmits NR channels in the 2.6 GHz and 900 MHz frequency bands and transmits the LP-WUS / LP-SS in the 900 MHz frequency band only.
[0074] In some deployment scenarios, the network node that transmits the low power signal and the NR signal is the same network node. In other deployment scenarios, the network node that transmits the low power signal and the NR signal can be different network nodes. When the network nodes are different, the network nodes have ideal backhaul connection and can exchange information in real time. When the network nodes are different and have non-ideal backhaul connection, the amount of information exchanged is limited and the latency is longer.
[0075] As shown in FIG. 3, network node 2 transmits the LP-WUS / LP-SS and other NR signals, and network node 1 transmits other NR signals but does not transmit the LP-WUS / LP-SS. UE 1 camps on cell 1, but there is no LP-WUS on cell 1, and UE 1 receives the LP-WUS on cell 2, i.e., the paging signal and the LP-WUS signal that UE 1 receives come from different network nodes and are on different frequency bands. UE 2 camps on cell 2 and also receives the LP-WUS on cell 2. The paging signal and the LP-WUS signal that UE 2 receives come from the same network node and are on the same frequency band. As shown in FIG. 4, network node 1 transmits the LP-WUS / LP-SS and other NR signals on cell 2, and transmits other NR signals only on cell 1. UE 1 camps on cell 1, but there is no LP-WUS on cell 1, and UE 1 receives the LP-WUS on cell 2, i.e., the paging signal and the LP-WUS signal that UE 1 receives come from the same network node but are on different frequency bands.
[0076] If the network node sending the LP-WUS / LP-SS and the network node sending other NR signals are different, or the LP-WUS / LP-SS and other NR signals are in different frequency bands / carriers / cells, the time of the frequency band / carrier / cell where the LP-WUS / LP-SS is located and the frequency band / carrier / cell where the other NR signals are located can be unsynchronized, for example, SFN misalignment, or frame timing misalignment, or slot misalignment, or OFDM symbol misalignment. The duplex multiplexing manner can also be different, for example, one is TDD and the other is FDD, or both are TDD but the uplink and downlink configurations of the TDD are different. This can increase the complexity of the network node to coordinate the LP-WUS / LP-SS and other NR signals, or increase the complexity of the UE to receive the LP-WUS / LP-SS and wake up the main receiver to receive other NR signals.
[0077] According to an implementation, the frequency band / carrier / cell where the LP-WUS / LP-SS is located is limited to be the same as, or a subset of, the frequency band / carrier / cell where the UE receives signals using the main communication module.
[0078] For example, for a UE in RRC idle / inactive state, the frequency band / carrier / cell where the LP-WUS / LP-SS is located is the same as the cell where the UE camps on, or the same as the frequency band / carrier / cell where the UE receives the paging message, or the same as the frequency band / carrier / cell for neighbor cell measurement. For a UE in RRC connected state, the frequency band / carrier / cell where the LP-WUS / LP-SS is located is the specific frequency band / carrier / cell where the UE is located, for example, Pcell or primary SCG cell or serving cell or activated serving cell.
[0079] Figure 5 gives an example, which limits the UE in RRC idle / inactive state to receive the LP-WUS only in the frequency band / carrier / cell where the UE camps on. UE1 camps on cell1, but there is no LP-WUS in cell1, so UE1 cannot use the LP-WUS. It can be seen that this limits the use range of the LP-WUS.
[0080] According to another implementation, the frequency band / carrier / cell where the LP-WUS / LP-SS is located can be different from the frequency band / carrier / cell where the UE receives signals using the main communication module, as in the examples in FIGS. 3-4.
[0081] The embodiments of the present application mainly aim at the case where the frequency band / carrier / cell where the LP-WUS / LP-SS is located can be different from the frequency band / carrier / cell where the UE receives signals using the main communication module, and are also applicable to the case where the frequency band / carrier / cell where the LP-WUS / LP-SS is located can be the same as the frequency band / carrier / cell where the UE receives signals using the main communication module.
[0082] The signal receiving method provided by the embodiments of the present application will be described in detail below in combination with the drawings, some embodiments, and application scenarios thereof.
[0083] FIG. 6 shows a flowchart of a signal receiving method according to an embodiment of the present application. As shown in FIG. 6, the signal receiving method includes the following steps:
[0084] Step 601: A terminal acquires first information.
[0085] Step 602: The terminal receives a first signal according to the first information, the first signal being a low-power consumption signal.
[0086] The first information includes at least one of the following:
[0087] First time information, the first time information being used to determine a first time position, the first time position being a time position of a frequency domain resource where the first signal is located;
[0088] Second time information, the second time information being used to determine a second time position, the second time position being a reference time position of a time domain resource of the first signal;
[0089] First configuration information, the first configuration information being used to configure a duplex mode of the frequency domain resource where the first signal is located.
[0090] In the embodiments of the present application, the terminal can be understood as a receiving end, and the terminal can include a first receiver and a second receiver. The first receiver can be understood as a low-power consumption receiver, and is used to receive the first signal, i.e., the first signal is a signal received by the terminal using the first receiver. The first signal can include at least one of an LP-SS and an LP-WUS, for example. The second receiver can be understood as a main receiver, and is used to receive other NR signals.
[0091] The "time position" in the embodiments of the present application can be understood as a specific time point or a specific time instant. For example, the terminal knows the first time position, and thus knows at which time point or time instant the first signal is sent in the frequency domain resource. For another example, the terminal knows the second time position, and thus knows the reference time point or reference time instant of the time domain resource of the first signal.
[0092] The "frequency domain resource" in the embodiments of the present application can include a frequency band, a cell, a bandwidth part (BWP), or a frequency domain region, etc.
[0093] In the embodiments of the present application, the terminal acquires first information, and receives a first signal according to the first information, where the first signal is a low-power-consumption signal; and the first information includes at least one of the following: first time information used to determine a first time position, the first time position being a time position of a frequency domain resource where the first signal is located; second time information used to determine a second time position, the second time position being a reference time position of a time domain resource of the first signal; and first configuration information used to configure a duplex mode of the frequency domain resource where the first signal is located. In this way, the terminal can determine the time position of the first signal by acquiring the first information, and thus can ensure that the terminal receives the first signal.
[0094] In some embodiments, the first time information includes at least one of the following:
[0095] absolute time of the first time position;
[0096] time offset of the first time position relative to a third time position, the third time position being a time position of a cell where a second signal is located.
[0097] The second signal is a signal received by the terminal using a second receiver, and the second signal can be understood as another NR signal. The second signal may, for example, include at least one of a synchronization signal block (SSB) and a paging signal.
[0098] In the case where the first time information includes the absolute time of the first time position, the terminal only needs to know the absolute time of the first time position to know where the first time position is. The absolute time may, for example, be coordinated universal time (UTC) or global positioning system (GPS) time.
[0099] In the case that the first time information includes a time offset of the first time position relative to the third time position, the terminal only needs to know where the third time position is and the time offset of the first time position relative to the third time position, and can know where the first time position is.

[0231] The following provides a plurality of specific embodiments to exemplarily illustrate the embodiments of the present application.
[0232] Embodiment 1
[0233] The network node provides the configuration information of the low-power signal for the UE. Among them, the reference time point of the configuration information for determining the low-power signal occasion (such as (LP-WUS / LP-SS occasion, LO) or the monitoring occasion (monitoring occasion, MO) of LP-WUS / LP-SS) is the first reference time point of the frequency domain resource (the frequency domain resource can be a frequency band, a cell, a BWP, a frequency domain area, etc.) where the low-power signal is located. For example, the first system frame of the LP-WUS / LP-SS. Or, the reference time point of the configuration information is the second reference time point of the cell where the terminal receives the signal using the main communication module, such as the second system frame. Among them, the first system frame or the second system frame is a predefined system frame, such as SFN 0, or a paging frame, or a specific system frame configured by the network node. Or, the second reference time point is the start time of the drx-onDurationTimer on the Pcell or the SpCell.
[0234] Optionally, the configuration information also includes Cyclic prefix (CP) information, such as normal CP or extended CP. If the CP information is not provided, the CP is determined according to the predefined rule, for example, the default is normal CP, or the default is the same as the CP type of the Paging information.
[0235] Optionally, the configuration information also includes SCS information. If the SCS information is not provided, the SCS is determined according to the predefined rule.
[0236] Optionally, the configuration information also includes the configuration information of FDD or TDD or SBFD. If it is TDD, but the uplink and downlink configuration information of TDD is not provided, the time slot type of TDD is determined according to the predefined rule.
[0237] It is assumed that a UE receives a LP-WUS / LP-SS at a first frequency point using a low power receiver (LP-WUR) and receives an SSB, paging, and other NR signals at a second frequency point using a main receiver (MR). The first frequency point and the second frequency point are the same or different, for example, the first frequency point and the second frequency point are both located in the frequency domain resource of the same cell, or the first frequency point and the second frequency point are located in different cells of the same frequency band, or the first frequency point and the second frequency point are located in different frequency bands.
[0238] Example 1
[0239] According to an implementation, the reference time point of the configuration information of the low power signal is a first system frame of the first frequency point, for example, SFN 0 of the first frequency point or a specific system frame of the first frequency point configured by the base station. According to another implementation, the reference time point of the configuration information of the low power signal is a second system frame of the second frequency point, for example, SFN 0 of the second frequency point or a specific system frame of the second frequency point configured by the base station. The second frequency point is the frequency point of the cell in which the SSB and / or paging is received by the main receiver (MR), or the frequency point of the Pcell, or the frequency point of the Camped cell. The base station configures the period and the time offset of the low power signal, and the time offset is a time offset relative to the first system frame or the second system frame. Whether the reference time point of the configuration information of the low power signal is the first system frame or the second system frame is predefined by the protocol or configured by the network node. The time unit of the period and the time offset of the low power signal configured by the base station is any one or a combination of a plurality of combinations of frames, subframes, slots, Orthogonal Frequency Division Multiplexing (OFDM) symbols, milliseconds (ms), microseconds (us), or nanoseconds (ns).
[0240] Optionally, the UE uses the nearest SFN 0 or the nearest system frame with the same index as the indicated specific system frame before receiving the configuration information as the first system frame or the second system frame. Alternatively, the UE uses the nearest SFN 0 or the nearest system frame with the same index as the indicated specific system frame after receiving the configuration information as the first system frame or the second system frame.
[0241] Optionally, the UE can take the first or last downlink system frame / downlink time slot / downlink symbol overlapping with the second system frame as the reference point, or the UE can take the first or last system frame / time slot / symbol overlapping with the second system frame as the reference point (considering that in a TDD system, one time slot / symbol can be a downlink time slot / symbol, or an uplink time slot / symbol, or a flexible time slot / symbol, embodiments of the present application do not limit this), and determine the time resource of the low-power signal according to the configured period and time offset of the low-power signal. Taking FIG. 8 as an example, the second system frame SFN0 of the second frequency point overlaps with SFN8 and SFN9 of the first frequency point, and the terminal can take the start point of SFN8 as the reference time point, and determine the position of LO / MO of the LP-SS according to the configured period and time offset of the low-power signal.
[0242] In some deployment scenarios, the time difference between the first system frame and the second system frame is small, for example, the two system frame numbers are aligned, and the time difference of the symbol boundary is less than a predefined transmission time difference. Then, the first system frame or the second system frame as the reference time point is equivalent. In some deployments, the first system frame and the second system frame are not aligned in time. If the first system frame is the reference time point, the UE can determine the time point of the first system frame according to the time difference between the first frequency point and the second frequency point. The time difference can be obtained by UE measurement or network node configuration, such as the method of embodiment 2. Taking FIG. 9 as an example, the time difference between the SFN of the second frequency point and the first frequency point is 2 system frames or 1022 system frames. The MR of the UE determines SFN0 of the first frequency point according to the time difference and SFN0 of the second frequency point, and determines the time position of the LP-SS in the first frequency point according to the time offset and period of the LP-SS.
[0243] Considering that there can be a timing error between the MR and the LR of the UE, the LR of the UE can need to slide to try to receive the low-power signal within a certain time range before / after the possible time position of the low-power signal determined by the LR according to the above method. The LR of the UE determines the timing of the LR according to the actual received time position of the LP-SS, for example, determines the boundary of the symbol, time slot, or frame of the frequency band of the LR, etc. The timing information can also be used to assist the reception of the LP-WUS.
[0244] For the UE in RRC connected state, the network node can configure the LP-WUS for controlling PDCCH monitoring. The configuration of the LP-WUS and the method for the UE to determine the LO / MO of the LP-WUS can be similar to the LP-SS described above. The reference time point can be the first frequency point or the second frequency point. The second frequency point can be the Pcell, or the Pscell, or a cell configured by the network node. Optionally, the cell configured by the network node is one of the serving cells or the activated cells of the UE.
[0245] Optionally, the network node can also configure a time offset for a slot where drx-onDurationTimer would start on the PCell or on the SpCell. The time offset can be in ms, us, or frame, subframe, slot, OFDM symbol. The SCS of the slot and OFDM symbol can be determined according to the SCS of the LP-WUS, or according to the SCS of the second frequency point. The UE determines a time point according to the time offset, and starts to monitor the LP-WUS in the first LP-WUS LO / MO no earlier than the time point.
[0246] This example is based on the LP-SS and the LP-WUS for the connected state. This example can also be applied to the LP-WUS for the idle state or the inactive state.
[0247] Example 2:
[0248] The reference time point of the configuration information of the low power consumption signal is the second system frame of the second frequency point, wherein the second system frame is a paging frame (PF). The paging frame is the paging frame associated with the paging message (Paging) associated with the LP-WUS, or the first paging frame in the associated paging frame. For example, one LP-WUS LO can be associated with multiple Paging occasions, if the multiple paging occasions are located in different system frames, the second system frame is the first paging frame in the multiple paging frames corresponding to the multiple paging occasions. The base station configures the time offset of the low power consumption signal, and the time offset is the time offset relative to the PF. The time unit of the time offset of the low power consumption signal configured by the base station is any one or a combination of frame, subframe, slot, OFDM symbol, ms, us or ns.
[0249] The time position of the LO / MO of the LP-WUS is determined according to the reference time point and a time offset of the LP-WUS. According to one implementation, the time offset of the LP-WUS is a time offset of a start point of a first LO of the LP-WUS from the reference time point. According to another implementation, the time offset of the LP-WUS is a start point of an OFDM symbol, or a slot, or a subframe, or a system frame in which the start point of the first LO of the LP-WUS is located, from the reference time point. According to another implementation, the time offset of the LP-WUS is a minimum time offset of a start point of an OFDM symbol, or a slot, or a subframe, or a system frame in which the start point of the first LO of the LP-WUS is located, from the reference time point. The start point of the first LO of the LP-WUS is a point of a first OFDM symbol, or a first slot, or a first subframe, or a first system frame after the time offset. Optionally, the OFDM symbol or the slot is determined according to a SCS of the low power signal, or a SCS of a specific signal of the frequency point of the reference time point, for example, a SCS of an SSB of the MR, or a SCS of the initial BWP, or a SCS of the Paging.
[0250] For example, the timing of the LR and the MR is off by half an OFDM symbol, and the configured time offset of the LP-WUS is minimum at the level of an OFDM symbol, then the time position determined according to the timing location of the start of the PF of the MR as the reference time point is in the middle of one OFDM symbol of the LR. To solve this problem, the UE can try to receive the LP-WUS in a time window of a certain range before and after this time point. For example, a time window of 1 OFDM symbol before and after. Or, to solve this problem, the reference time point is determined according to the timing location of the start of the PF and the configured time offset of the low-power signal. The start of the LO of the LP-WUS is no earlier than the start of the first slot or the first OFDM symbol of the reference time point. As shown in FIG. 11, the start of the LO of the LP-WUS is the start of the OFDM symbol S1 of the LR frequency point. Or, the start of the LO of the LP-WUS is the first OFDM symbol overlapping the reference time point plus the time offset, such as symbol S0 in FIG. 11. Or, without limiting whether it is symbol S0 or S1, the UE can try to receive the LP-WUS in a time window, for example, try to receive the LP-WUS with symbol S0 and S1 as the start of the LO. This can give the network node better flexibility. Or, the UE takes the first or last system frame / slot / symbol overlapping the second system frame as the time reference point, and determines the time resource of the low-power signal according to the configured time offset of the low-power signal. For example, as shown in FIG. 12, the paging frame (SFN X) of the second frequency point overlaps the SFN8 and SFN9 of the first frequency point. Taking the start of the SFN8 as the reference time point, the position of the LO of the LP-WUS is determined according to the configured time offset (for example, 40 frames + 3 symbol offsets, where the symbol duration is determined according to the SCS of the LP-WUS) of the LP-WUS.
[0251] The present example can be applicable to the LP-WUS configured relative to the PO / PF.
[0252] Embodiment 2
[0253] In some deployments, the timing of the first frequency point and the second frequency point is not synchronized, for example, the SFN, slot or OFDM symbol index and boundary of the cell receiving the signal of the MR and the LR are not aligned.
[0254] According to an implementation, the UE needs to obtain the timing offset information of the MR and the LR. For example, the period and offset of the LO / MO of the LP-SS / LP-WUS are determined with respect to SFN0 of the first frequency point, and the UE needs to obtain the timing offset information of the MR and the LR to determine the location of the reference time point. The UE can measure the synchronization signals of the two frequency points by the MR to determine the timing difference of the two frequency points. For example, the MR receives the SSBs on the Pcell or the Camped cell (the cell receiving the Paging) and the cell where the LP-WUS / LP-SS is located, respectively, and determines the SFN offset and the frame boundary offset of the two cells by the time positions (indices and starting points) of the SFNs, subframes, slots and OFDM symbols corresponding to the detected SSBs on the two cells, respectively. For example, SFN offset = (SFNcell1-SFNcell2) mod 1024, where SFNcell1 is the SFN X1 of the Pcell or the Camped cell, and SFNcell2 is the SFN X2 of the cell where the LP-WUS / LP-SS is located, and SFN X2 is the system frame in the cell where the LP-WUS / LP-SS is located that is closest in time to the starting point of the SFN X1 of the Pcell or the Camped cell. where TFrameBoundaryCell1 is the time of the starting point of one SFN of the Pcell or the Camped cell received by the UE, and TFrameBoundaryCell2 is the time of the starting point of one SFN of the cell where the LP-WUS / LP-SS is located (the SSB is received by the MR of the UE on this cell), and this SFN is closest in time to the time of the SFN of the Pcell or the Camped cell. The time granularity can be at the level of a subframe, or a slot, or an OFDM symbol or a sampling point Ts. Wherein the time length of the slot, the OFDM symbol or the Ts is based on a given SCS. The given SCS can be predefined, for example, the SCS of the LP-WUS / LP-SS, or the SCS of the Paging, or the SCS of the SSB of the Pcell or the Camped cell, or the SCS of the initial BWP, or configured by the network node.
[0255] Optionally, the network node provides configuration information for measuring the timing difference. Including at least one of the following: cell information for measuring the timing difference, for example, which two cells have the timing difference, frequency point information of the cell to be measured, cell ID information, frequency domain information of the SSB, index information of the SSB, time information of the SSB, whether the result of the measured timing difference needs to be reported.
[0256] According to one example, the UE can determine the reference time point of the low power signal based on the system frame on the Pcell or the Camped cell and the time difference of the two cells, e.g. determine the time position of the first system frame of the cell where the LP-WUS / LP-SS is located.
[0257] According to another implementation, the absolute time information, e.g. time stamping information, of the cell where the LP-WUS / LP-SS is located can be obtained by reading the system information, e.g. System Information Block 9 (SIB9), on this cell via the MR. Alternatively, the UE reads the system information SIB9 on the Pcell or the Camped cell, reads the system information SIB9 on the cell where the LP-WUS / LP-SS is located, and obtains the respective absolute time information.
[0258] According to another implementation, the network node can indicate the timing difference of the two frequencies (the timing difference of the transmitter). For example, at least one of the SFN offset, slot offset, OFDM offset and Frame boundary offset. For example, the network node indicates the SFN offset and Frame boundary offset of the two frequencies. Alternatively, the UE assumes the SFN of the two frequencies is consistent, the network node does not need to indicate the SFN offset, and the network node indicates the slot offset. The time granularity of the Frame boundary offset can be subframe, or slot, or OFDM symbol or sampling point Ts level. The time length of slot, OFDM symbol or Ts is based on the given SCS. The given SCS can be predefined, e.g. the SCS of the LP-WUS / LP-SS, or the SCS of the Paging, or the SCS of the SSB of the Pcell / pScell or the Camped cell, or the SCS of the initial BWP, or the minimum of all the SCS of the Pcell / pScell and the maximum of the SCS of the LP-WUS / LP-SS, or the SCS configured by the network node.
[0259] Embodiment 3
[0260] In some deployments, the duplex mode of the first frequency and the second frequency can be different, e.g. the cells where the MR and the LR receive the signals, one works in FDD mode, the other works in TDD mode. Alternatively, both work in TDD mode, but the uplink and downlink configuration of TDD is different. Alternatively, it also includes whether it is SBFD, and the configuration information of SBFD can be the same or different.
[0261] In one implementation, the network node provides the UE with the duplex information of the cell where LP-WUS / LP-SS resides, including TDD or FDD, TDD uplink / downlink configuration, and SBFD configuration. In another implementation, the UE can obtain the duplex information of the cell where LP-WUS / LP-SS resides by reading system information from the MR (Mobile Registry).
[0262] Optionally, if the cell where LP-WUS / LP-SS resides is operating in TDD mode, the network node provides the UE with a reference time start point for the TDD uplink / downlink configuration type (pattern). For example, for a TDD uplink / downlink configuration with a period of 10ms, the network node configures the offset of this 10ms start point relative to the start point of a system frame (or an even-numbered system frame) at the second frequency point.
[0263] In one implementation, the UE determines the valid LP-WUS / LP-SS LO / MO based on the TDD uplink / downlink configuration. If an LP-WUS / LP-SS MO overlaps with at least one TDD UL symbol, this MO is invalid. The UE does not need to attempt to receive LP-WUS / LP-SS from invalid MOs. In another implementation, the UE does not need to determine the validity of the LP-WUS / LP-SS MO based on the TDD uplink / downlink configuration. Accordingly, a more reasonable implementation is that the base station ensures that among a group of LP-WUS / LP-SS MOs, for example, among a group of LP-WUS / LP-SS MOs in the same beam, at least one MO does not overlap with a TDD UL symbol and can transmit LP-WUS / LP-SS.
[0264] In embodiments 1 to 3, a typical implementation is that the UE's MR obtains the configuration information of LP-WUS / LP-SS and calculates the LO / MO time and location information of LP-WUS / LP-SS, and informs the LR of the time and location information, for example, through the internal interface between the MR and the LR.
[0265] Example 4
[0266] In some deployments, the timing of the first and second frequency points may be out of sync. For example, the SFN, slot, or OFDM symbol index and boundary of the cell where the MR and LR signals are located may not be aligned.
[0267] The network node needs to know the time difference between the two frequency points to determine the LO / MO position of LP-WUS / LP-SS and provide the UE with LP-WUS / LP-SS configuration information. Optionally, the network node can also provide the UE with the time difference between the two frequency points.
[0268] According to an implementation, the first network node transmitting the LP-WUS / LP-SS and the second network node transmitting other NR signals exchange time information. For example, the first / second network node sends the time information of a specific cell under this network node to the second / first network node. For example, the absolute reference time of the specific cell and the time difference of the start of SFN0, or the absolute time (such as UTC or GPS time) corresponding to SFN0, or the system frame / subframe / slot / OFDM symbol index corresponding to the time position of sending the time information. The exchange of time information can be through the Xn interface or other interfaces, such as implementation-based interfaces.
[0269] In some deployments, the duplex modes of the first frequency point and the second frequency point can be different. The cells where the signals received by the MR and the LR work in FDD mode, and the other works in TDD mode. Or, both work in TDD mode, but the uplink and downlink configurations of TDD are different.
[0270] The network node needs to know the duplex mode of the two frequency points, and more reasonably configure the LO / MO position of the LP-WUS / LP-SS.
[0271] Optionally, the network node can also provide the UE with the duplex information of the two frequency points. According to an implementation, the first network node transmitting the LP-WUS / LP-SS and the second network node transmitting other NR signals exchange duplex information. For example, the second network node sends the duplex information of the cell where the LP-WUS / LP-SS is located to the first network node.
[0272] In some deployments, the CPs of the first frequency point and the second frequency point can be different. According to an implementation, the first network node transmitting the LP-WUS / LP-SS and the second network node transmitting other NR signals exchange CP information, such as normal or extended CP.
[0273] In some deployments, the SCSs of the first frequency point and the second frequency point can be different. According to an implementation, the first network node transmitting the LP-WUS / LP-SS and the second network node transmitting other NR signals exchange SCS information.
[0274] Embodiment 5
[0275] The frequency domain resource where the low-power signal is located can be determined according to at least one of the following ways:
[0276] The network node configures the center frequency of the lowest subcarrier or the frequency domain information of the lower edge of the lowest subcarrier of the LP-WUS / LP-SS;
[0277] information of a frequency domain reference point of a carrier, a cell, a BWP, or a frequency band where the low power consumption signal of the network node is located;
[0278] information of a frequency domain offset of the low power consumption signal of the network node relative to a reference frequency domain resource point;
[0279] SCS information.
[0280] The frequency domain reference point is: frequency domain information of a point A of the carrier, the cell, the BWP, or the frequency band where the low power consumption signal is located, or a subcarrier 0 of a common RB 0, or frequency domain information of an SSB of the carrier, the cell, the BWP, or the frequency band where the low power consumption signal is located.
[0281] Any of the above frequency domain information is configured based on an ARFCN or a sync raster.
[0282] Embodiment 6
[0283] According to an implementation, the frequency domain resource where the low power consumption signal is located is within a bandwidth of one cell.
[0284] Optionally, the cell is a cell where the UE camps. For example, a UE in an RRC idle state can camp in two cells, where the second cell is a cell where the UE receives SSBs, system information, or paging information, and the first cell is a cell where the UE receives LP-WUS / LP-SS in an LR. In the first cell, the network node can also transmit SSBs, system information, and other NR signals receivable by the UE in an MR. The network node can configure the UE with information of the first cell.
[0285] Optionally, the cell is a measurement cell of the UE. The network node can configure the UE with measurement parameters of the cell, such as parameters of SSBs of the cell, a cell ID, and the like.
[0286] According to an implementation, at least from the perspective of the UE, the frequency domain resource where the low power consumption signal is located can be independent of a cell.
[0287] Embodiment 7
[0288] The UE can report at least one of the following capabilities:
[0289] Whether the UE can support non-aligned SFN, non-aligned slot, and / or non-aligned frame timing of the first frequency point and the second frequency point;
[0290] Whether the UE can support different duplex parameters of the first frequency point and the second frequency point;
[0291] Whether the SCS of the first frequency point and the second frequency point can be supported to be different;
[0292] Whether the SCS of the LP-WUS / LP-SS and the paging can be supported to be different;

[0294] Whether the first frequency point and the second frequency point can be supported to be in different cells;
[0295] Whether the first frequency point and the second frequency point can be supported to be in different bands;
[0296] Whether the first frequency point and the second frequency point can be supported to be in different FR ranges.
[0297] The network node can determine whether or how to configure the LP-WUS / LP-SS according to the capability reported by the UE.
[0298] In summary, the embodiments of the present application provide how the base station configures the low-power consumption signal and how the terminal determines the time position of the LP-WUS / LP-SS LO on the low-power consumption receiver frequency point in the deployment scenario of time asynchronization or different duplex modes of the LR and the MR in different frequency points, which can enable the use of the LP-WUS in more network deployment scenarios.
