[0002] The New Radio (NR) introduces a low-power wake-up module / receiver and low-power wake-up signals.

[0048] To better understand the technical solution provided in this application, the related technologies involved in this application will be introduced first.

[0049] 1. LP-SS and LP-WUR

[0050] 3GPP will start the research work on introducing Low Power Wake Up Receiver (LP WUR) / wake-up signal (WUS) in mobile cellular systems at Rel-18. The basic working principle of LP WUR is as follows: The receiving end includes a first module and a second module. The first module is the main communication module, which is used to receive and transmit communication data from the sending end. The second module is a low-power module, which is used to receive the low-power wake-up signal (LP-WUS) and the low-power synchronization signal (LP-SS) sent by the sending end. The low-power wake-up signal is used to wake up the main communication module at the receiving end, and the low-power synchronization signal is used to provide time reference information and other information for receiving the low-power wake-up signal. For example, it is used for RRM measurements of the serving cell and can also provide wake-up link management. As Figure 2 shown, when the first module is not awakened by the second module, it remains in the off state and does not send or receive data. When downlink data arrives and the second module detects the wake-up signal sent by the sending end and the wake-up signal contains the information of this terminal, the second module triggers the first module to switch from the off state to the working state for data reception and transmission. The second module can be continuously turned on or not continuously turned on. When the second module is turned on, it can receive the low-power wake-up signal and the low-power synchronization signal.

[0051] 2. Beam-based transmission in the NR system

[0052] In the NR system, the base station can use different beams to send different SSBs and achieve coverage in all directions through beam sweeping. The number of SSBs can be configured through the ssb-PositionsInBurst parameter. The SSB index of each SSB is different. The SSB index is carried by the Demodulation Reference Signal (DMRS) of the Physical Broadcast Channel (PBCH), or by the DRMS of the PBCH and the PBCH payload. The SSB can be sent periodically. All SSBs indicated by ssb-PositionsInBurst are sent within one period. All these SSBs can be called a group of SSBs or an SSB burst. The UE assumes that different SSB indexes do not satisfy the Quasi co-location (QCL) relationship, and SSBs with the same SSB index satisfy the QCL relationship and can be combined. For example, the SSBs with the same SSB index in different periods are combined to obtain the measurement results of the same beam.

[0053] An SSB burst can be located in the first half or the second half of a frame. Within a half-frame, the time position of an SSB burst is pre-defined by the standard.

[0054] In the licensed band, within one period, there is only one occasion for an SSB, and the time position is pre-defined by the standard. In the unlicensed band, to reduce the impact of listen-before-talk (LBT), within one period, an SSB can have N occasions, where N ≥ 1, and the time positions of the N occasions are pre-defined by the standard. The base station can send this SSB at any position among the N occasions. The time relationship of multiple occasions of SSBs with different SSB indices is as follows: the first occasions of each SSB index are arranged in sequence, then the second occasions of each SSB index are arranged in sequence, and so on. Within each period, the occasion positions of all SSBs and the corresponding relationship between the SSB index and the occasion are the same. For example, the first 8 occasions of each period correspond to the first occasions of SSB1 - 8, and the last 8 occasions of each period correspond to the second occasions of SSB1 - 8. The UE assumes that SSBs with different SSB indices do not satisfy the QCL relationship, and SSBs with the same SSB index satisfy the QCL relationship and can be merged. For example, the SSBs with the same SSB index in different periods are merged to obtain the measurement results of the same beam.

[0055] However, in the existing NR system, the occasions of each SSB are pre-defined by the standard. Within each period, the position of the occasion, the corresponding relationship between the occasion and the SSB index, and the corresponding relationship between the beam of each SSB index are unchanged. And each occasion is located in the same or adjacent slots. Each SSB index is indicated by DMRS, or by DMRS + PBCH payload. For other signals in the NR system, such as the Channel State Information Reference Signal (CSI-RS), if the base station uses the same beam to send, the SSB index of the QCL reference signal can be configured.

[0056] For low-power signal transmission, the existing SSB occasions cannot meet the requirements. For example, the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied by a low-power signal is usually greater than that of an SSB. An SSB occasion cannot carry a low-power signal, and the position of the SSB occasion is relatively fixed. The SSB index transmitted within the occasion and the beam corresponding to the SSB are relatively fixed, lacking flexibility and potentially having a greater impact on the transmission of other NR signals. In addition, since the information that a low-power signal can carry is limited, for example, an LP-SS sequence-based signal may not be able to carry an LP-SS index. Therefore, the UE cannot reuse the method of determining whether multiple SSBs meet QCL based on the SSB index to determine whether multiple LP-SSs meet QCL. Also, it is impossible to reuse the method of configuring the SSB index as QCL reference signal information to determine the QCL relationship between LP-SS and LP-WUS.

[0057] Therefore, in the related art, no solution has been given on how a terminal receives a low-power signal in the case of multi-beam transmission. To address this problem, an embodiment of the present application provides a solution for receiving a low-power signal.

[0058] The following will, with reference to the accompanying drawings, elaborate on the solution for receiving a low-power signal provided by the embodiments of the present application through some embodiments and their application scenarios.

[0059] Figure 3 FIG. shows a schematic flowchart of a method for receiving a low-power signal in an embodiment of the present application. This method 300 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. As Figure 3 shown, the method may include the following steps.

[0060] S310, the terminal determines at least one candidate occasion for the target low-power signal according to the resource parameters configured for the target low-power signal.

[0061] In an embodiment of the present application, the terminal may determine at least one candidate occasion of the target low-power signal according to at least one of the resource parameters configured by the network-side device for the target low-power signal and the resource parameters configured by the protocol. For example, all the parameters included in the resource parameters may be configured by the network-side device or the protocol, or a part of the parameters included in the resource parameters are configured by the network-side device, and the other part of the parameters are predefined by the protocol. For example, the period and the number of candidate occasions are configured by the network-side device, and the time length of each candidate occasion is configured by the protocol. Also for example, the period, the number of candidate occasions, and the time length of each candidate occasion are configured, but the spatial characteristics are predefined by the protocol.

[0062] For example, the network-side device configures the resource parameters of LP-SS / LP-WUS for the UE. The UE determines the resources of LP-SS / LP-WUS according to the resource parameters of LP-SS / LP-WUS configured by the network-side device for the UE and the resource parameters predefined by the standard. For example, the UE determines the candidate occasion of LP-SS / LP-WUS and the time domain, frequency domain, code domain, spatial domain information, and channel structure of LP-SS / LP-WUS transmitted in each candidate occasion. Among them, the time domain, frequency domain, code domain, and spatial domain information may include: spatial transmission characteristics, spatial reception characteristics, Doppler characteristics, time delay characteristics, etc.

[0063] In an optional implementation manner, the resource parameters include at least one of, but are not limited to, the transmission period of the target low-power signal, the length of the reception time window of the target low-power signal, the candidate occasion information included in the reception time window of the target low-power signal, the candidate occasion information included in one transmission period, the spatial characteristics corresponding to each candidate occasion, and the repetition times of the target low-power signal.

[0064] Among them, the transmission period of the target low-power signal is used to indicate the transmission period of the target low-power signal. The length of the reception time window of the target low-power signal is used to indicate the length of the reception time window of the target low-power signal. The candidate occasion information included in the reception time window of the target low-power signal is used to indicate the candidate occasions included in the reception window of the target low-power signal. The candidate occasion information included in one transmission period is used to indicate the candidate occasions included in the transmission period of the target low-power signal. The spatial characteristics corresponding to each candidate occasion are used to determine the spatial characteristics of the target low-power signal transmitted on each candidate occasion. The repetition times of the target low-power signal are used to indicate the number of times the target low-power signal is repeatedly transmitted.

[0065] Optionally, the candidate occasion information included within the reception time window of the above-mentioned target low-power signal or the candidate occasion information included within one transmission period includes, but is not limited to, at least one of the time length of one candidate occasion, the time interval between two adjacent candidate occasions, the time interval between two adjacent occasion sets, the number of candidate occasions, the number of occasion sets, and the number of candidate occasions within one occasion set.

[0066] Optionally, the number of candidate occasions within each occasion set is the same.

[0067] Optionally, the number of candidate occasions within each occasion set may also be different. For example, limited by the reception time window length, the number of candidate occasions within each occasion set is different. Or the network-side device may configure the number of candidate occasions for each occasion set separately.

[0068] Optionally, a time interval may be configured in the above resource parameters, and this time interval is the time interval between each candidate occasion within one target time period.

[0069] For example, Figure 4 in [specific context], the values of Offset_i1, Offset_i2, Offset_i3, Offset_i4, Offset_j1, Offset_j2, Offset_j3 are the same, and the network-side device indicates or the protocol predefines and indicates one value. Figure 5 in [specific context], the values of Offset_j1, Offset_j2, Offset_j3, Offset_j4, Offset_j5, Offset_j6, Offset_i are the same, and the network node only indicates one value.

[0070] The terminal can determine the time resources of each occasion based on the time resources of the first occasion in each period, this time interval, and the number of candidate occasions.

[0071] Optionally, two time intervals may be configured in the above resource parameters. One time interval is the time interval between each candidate occasion within one occasion set, and the other time interval is the time interval between each occasion set.

[0072] For example, Figure 4 in [specific context], Offset_i1, Offset_i2, Offset_i3, Offset_i4 are the same, which is the time interval between each candidate occasion within one occasion set, and the values of Offset_j1, Offset_j2, Offset_j3 are the same, which is the time interval between each occasion set.Figure 4 Among them, Offset_i is the time interval of each candidate occasion within a candidate occasion set (occasion set), and the values of Offset_j1, Offset_j2, Offset_j3, Offset_j4, Offset_j5, and Offset_j6 are the same, which are the time intervals between each candidate occasion set.

[0073] Figure 6 Among them, Offset_i1, Offset_i2, Offset_i3, Offset_i4, Offset_i5, and Offset_i6 are the same, which are the time intervals of each candidate occasion within a candidate occasion set (occasion set). Offset_j is the time interval between candidate occasion sets.

[0074] The terminal can determine the time resources of each occasion based on the time resources of the first occasion in each period, the above two time intervals, and the number of occasions.

[0075] Optionally, multiple time intervals can also be configured in the above resource parameters. One time interval is the interval between each occasion within an occasion set, and the other time intervals are the time intervals between each occasion set, and each occasion set may not be exactly the same. The terminal can determine the number of occasion Sets according to the number of time intervals, or the number of occasion sets is pre-defined by the protocol or configured by the network side device.

[0076] The terminal can determine the time resources of each occasion based on the time resources of the first occasion in each period, the multiple time intervals, and the number of occasions.

[0077] Optionally, the spatial characteristics corresponding to each candidate occasion may include at least one of the following 1) to 6).

[0078] 1), within the same target time period, the target low-power signals corresponding to each candidate occasion in the same candidate occasion set have the same spatial characteristics. That is to say, each occasion in an occasion set corresponds to the same characteristics. For example, the same spatial reception characteristics, or satisfying the same Doppler and time delay parameters.

[0079] Such as Figure 4 and Figure 5As shown, assume that within one period, the number of LP-SSs sent by the network-side device is L = 4, and the number of occasions for each LP-SS is N = 2. Then the total number of occasions is O = 8. Then, the N occasions of one LP-SS form an occasion set. Different LP-SSs correspond to different occasion sets. Among the N occasions of one LP-SS, the network-side device can send the LP-SS in only one occasion.

[0080] The network-side device can configure reference signals. For example, configure LP-SS or SSB as the reference signal for LP-WUS, and it is considered that the reference signal has the same spatial reception characteristics as LP-WUS. For instance, the network-side device configures SSB1, SSB2, SSB3, SSB4 as reference signals. Then these 4 SSBs are the 4 occasion sets of LP-WUS in sequence, and LP-WUS has the same spatial reception characteristics.

[0081] 2) Within the same target time period, the target low-power signals corresponding to the respective candidate occasions in the same candidate occasion set have different spatial characteristics. That is to say, the respective occasions in an occasion set can correspond to different characteristics.

[0082] For example, as Figure 5 As shown, assume that within one period, the number of LP-SSs sent by the network-side device is L = 4, and the number of occasions for each LP-SS is N = 2. Then the total number of occasions is O = 8. The network-side device or protocol can configure two occasion sets, and the occasion time positions in each occasion set are relatively concentrated. The network-side device only sends 2 LP-SSs in the 8 occasions. For example, send 2 LP-SSs in only one occasion, or send only one LP-SS in each occasion.

[0083] 3), within the same target time period, the target low-power signals corresponding to the respective candidate occasions whose candidate occasion positions or candidate occasion indexes satisfy a predefined relationship have the same spatial characteristics.

[0084] Among them, the terminal can assume that the occasion index corresponding to the i-th occasion within the reception time window of a target low-power signal or within one period is i or i - 1. For example, if the value of occasion index starts from 0, then the occasion index of the 1st occasion is 0. Alternatively, the terminal can assume that the occasion set index corresponding to the i-th candidate occasion set within the reception time window of a target low-power signal or within one period is i or i - 1. The relationship between the occasion index of each occasion in a group of occasions corresponding to an Occasion set i and the occasion set index i is predefined or can also be configured by the network-side device.

[0085] For example, if occasion index i belongs to occasion set j when (i mod L) = j, or if occasion index i belongs to occasion set j when floor(i / N) = j, where L and N are configured or predefined by the standard. Among them, the characteristics of the target low-power signal are the same spatial reception characteristics. The network-side device can configure a reference signal. For example, LP-SS or SSB is configured as the reference signal for LP-WUS, and it is considered that the reference signal has the same spatial reception characteristics as LP-WUS.

[0086] 4), The target low-power signals corresponding to each candidate occasion within the same target time period have the same spatial characteristics. For example, the network-side device can configure a reference signal, and the reference signal has the same spatial characteristics as the LP-WUS corresponding to each candidate occasion of LP-WUS.

[0087] 5), Within different target time periods, the target low-power signals corresponding to each candidate occasion in the same candidate occasion set have the same spatial characteristics.

[0088] Among them, 5) can be combined with 1), then within the same or different target time periods, the target low-power signals corresponding to each candidate occasion in the same candidate occasion set have the same spatial characteristics.

[0089] 6), Within different target time periods, the target low-power signals corresponding to each candidate occasion in the same candidate occasion set do not have the same spatial characteristics.

[0090] Among them, if 6) can be combined with 1), then within the same target time period, the target low-power signals on each candidate timing in the same candidate timing set satisfy the same spatial characteristics. Within different target time periods, the target low-power signals on each candidate timing in the same candidate timing set do not satisfy the same spatial characteristics.

[0091] 7), within different target time periods, the target low-power signals corresponding to each candidate timing in two candidate timing sets that satisfy the first predetermined relationship have the same spatial characteristics.

[0092] Among them, if 7) can be combined with 3), then within the same or different target time periods, the target low-power signals corresponding to each candidate timing in two candidate timing sets that satisfy the first predetermined relationship have the same spatial characteristics.

[0093] For example, if occasion set i and occasion set j satisfy (i mod L1) = (j mod L2), then within different target time periods, the target low-power signals on the product candidate timings in occasion set i and occasion set j satisfy the same spatial characteristics. Among them, L1 can be the number of signals within a transmission period of the target low-power signal corresponding to occasion set i, and L2 is the number of signals within a transmission period of the target low-power signal corresponding to occasion set j.

[0094] In an alternative implementation, the spatial domain characteristic of the target low-power signal can be the same spatial reception characteristic. The network-side device can configure a reference signal. For example, LP-SS or SSB is configured as the reference signal for LP-WUS, and it is considered that the reference signal and LP-WUS have the same spatial reception characteristic.

[0095] Optionally, the configured reference signal information includes the signal type, such as LP-SS or SSB. The configured reference signal information may also include one of the signal index, the occasion set index, the occasion index, and the resource configuration index, such as the LP-SS index, the SSB index, or the index of the LP-SS occasion, etc.

[0096] The configured reference signal information may include only one reference signal or a set of reference signals. When configured as a set of reference signals, each reference signal can be considered as the reference signal for each occasion set in sequence. If the number of occasion sets L is not equal to the number of configured reference signals, the relationship between each reference signal and each occasion set can be determined according to predefined rules. For example, if the number of occasion sets is L and the number of configured reference signals is Lr, and L / Lr = A, then every A occasion sets correspond to one reference signal.

[0097] If no reference signal information is configured, it can be understood that there is no reference signal, or the reference signal is determined according to predefined rules. For example, the SSB indicated in ssb-PositionsInBurst is used as the reference signal.

[0098] When the LP-WUR receives the SSB signal, although it may not be able to receive the DMRS and PBCH of the PBCH and cannot directly obtain the SSB index, the LP-WUR can determine the SSB index of the received SSB according to the time information of the main receiver (MR) and the time position corresponding to the SSB index.

[0099] In an optional implementation, the resource parameters configured by the network-side device or protocol may include multiple sets of resource parameters. During a target time period, the spatial characteristics corresponding to each of the candidate timing instants satisfy one of the following 1) to 3).

[0100] 1) The target low-power signals corresponding to each of the candidate timing instants configured in one set of the resource parameters have the same signal characteristics. That is to say, the target low-power signals detected at each of the candidate timing instants configured in a segment of resource parameters have the same signal characteristics.

[0101] 2) The target low-power signals corresponding to the candidate timing instants whose candidate timing positions or candidate timing indices satisfy a predefined relationship among the candidate timing instants configured in one set of the resource parameters have the same spatial characteristics. That is to say, among the candidate timing instants configured in a segment of resource parameters, the target low-power signals detected at multiple candidate timing instants whose candidate timing positions or candidate timing indices satisfy the predefined relationship have the same signal characteristics.

[0102] 3) One set of the resource parameters is configured with multiple candidate timing sets, and the target low-power signals corresponding to each of the candidate timing instants in the same candidate timing set have the same signal characteristics. That is to say, among the multiple candidate timing sets configured in a segment of resource parameters, the target low-power signals detected at each of the candidate timing instants in the same candidate timing set have the same signal characteristics.

[0103] For example, the network-side device configures one or more sets of resource parameters for LP-SS, or the network-side device configures one or more sets of resource parameters for LP-WUS. Among them, each occasion within a set of resources corresponds to the same characteristic. For example, the same spatial reception characteristic or the same Doppler and time delay parameters are satisfied.

[0104] For example, the network-side device configures 4 sets of LP-WUS resource parameters. The LP-WUS resources corresponding to each set of LP-WUS resource parameters correspond to the same QCL type A (type-A) or QCL type D (type-D). It can be considered that each set of LP-WUS resources corresponds to an LP-WUS resource index or LP-WUS index. The network-side device can also configure a reference signal LP-SS for each set of LP-WUS, and it is considered that the LP-SS and LP-WUS have the same characteristics. In this example, it can be considered that there is no occasion set, or one set of LP-WUS corresponds to an occasion set, and each occasion within this occasion set corresponds to the same characteristic. Or, as Figures 3 to 5 shown, multiple occasion sets represent multiple reception time windows.

[0105] For another example, the network-side device configures one set of resource parameters for LP-SS, and the network-side device configures one set of resource parameters for LP-WUS. Among them, multiple occasion sets are configured within one set of resource parameters, and each occasion within each occasion set corresponds to the same characteristic. Different occasion sets may correspond to different characteristics, such as different spatial reception characteristics or different Doppler and time delay parameters.

[0106] S312, the terminal detects the target low-power signal sent by the network-side device in the at least one candidate occasion.

[0107] After the terminal determines at least one candidate occasion for the target low-power signal, it can determine that the network-side device may send the target low-power signal in the at least one candidate occasion. Therefore, the terminal detects the target low-power signal sent by the network-side device in the at least one candidate occasion.

[0108] S314, the terminal determines the spatial characteristics of each detected target low-power signal according to the detected target low-power signal, where the spatial characteristics include at least one of the following: spatial reception characteristic, Doppler delay parameter, time delay parameter.

[0109] In an embodiment of the present application, the terminal may determine at least one of the indexes of each candidate timing, the indexes of each candidate timing set, and the indexes of each target low-power signal according to the above resource parameters. According to at least one of the index of the candidate timing where the detected target low-power signal is located, the index of the candidate timing set, and the index of the target low-power signal, the terminal may determine the spatial characteristics of the detected target low-power signal.

[0110] In an embodiment of the present application, after the terminal detects a target low-power signal on one or more target timings among the at least one candidate timing, it may determine the spatial characteristics of each detected target low-power signal according to each detected target low-power signal. Thus, in the case of multi-beam transmission, the terminal can detect the target low-power signal sent by the network-side device on at least one candidate timing according to the resource parameters configured by the network-side device or the protocol, and determine the spatial characteristics of each detected target low-power signal, realizing the reception of the low-power signal.

[0111] In an optional implementation manner, the target low-power signal may include at least one of a first low-power signal and a second low-power signal, and the first low-power signal and the second low-power signal are low-power signals of different types. In this optional implementation manner, the target low-power signal may include low-power signals of different types. For example, the target low-power signal may include at least one of LP-WUS, LP-SS, and SSB. For example, for OFDM-based LP-WUR, the first low-power signal and the second low-power signal may be LP-WUS and SSB respectively. For OOK-based LP-WUR, the first low-power signal and the second low-power signal may be LP-WUS and LP-SS respectively.

[0112] In an optional implementation manner, the above resource parameters may include the resource parameters configured for the first low-power signal and the resource parameters configured for the second low-power signal.

[0113] Optionally, the resource parameters configured for the first low-power signal and the resource parameters configured for the second low-power signal may be independent of each other. The terminal determines at least one candidate timing of the first low-power signal according to the resource parameters configured for the first low-power signal, and determines at least one candidate timing of the second low-power signal according to the resource parameters configured for the second low-power signal. For example, the protocol or the network-side device may configure the resource parameters of LP-SS and LP-WUS respectively. The terminal determines the resources of LP-SS and LP-WUS according to the parameters of LP-SS and LP-WUS respectively.

[0114] Alternatively, the resource parameters configured for the first low-power signal and the resource parameters configured for the second low-power signal may be interdependent. For example, for the time resource parameters included in the resource parameters, the network-side device or protocol may configure the time resource parameters for the first low-power signal, and configure the time offset parameter of the second low-power signal relative to the first low-power signal for the second low-power signal. In this case, the terminal may determine the time resource information of at least one first candidate timing of the first low-power signal based on the time resource parameters configured for the first low-power signal, and then determine the time resource information of at least one second candidate timing of the second low-power signal based on the time resource information of at least one first candidate timing of the first low-power signal and the time offset parameter.

[0115] For example, the protocol or network-side device configures the resource parameters of the first low-power signal and at least configures the time offset parameter of the second low-power signal relative to the resources of the first low-power signal. The terminal determines the resources of the first low-power signal according to the parameters of the first low-power signal, and determines the resources of the first low-power signal according to the parameters of the first low-power signal and the parameters of the second low-power signal relative to the resources of the first low-power signal. Among them, the first low-power signal may be LP-SS, and the second low-power signal is LP-WUS. Alternatively, the first low-power signal may be LP-WUS, and the second low-power signal is LP-SS.

[0116] In one implementation, the time offset parameter may be the time offset between the first candidate timing of the first low-power signal and the first candidate timing of the second low-power signal within a target time period. Then, the terminal may determine the time position of the first second candidate timing of the second low-power signal according to the time resource information of the first first candidate timing of the first low-power signal, and then determine the time positions of other second candidate timings of the second low-power signal within the target time period according to the time position of the first second candidate timing of the second low-power signal, where the other second candidate timings are the second candidate timings of the second low-power signal other than the first second candidate timing within the target time period.

[0117] For example, a network-side device configures a time offset parameter. The time offset parameter may be the time offset between the first candidate position (occasion) of the first low-power signal and the first candidate position (occasion) of the second low-power signal within a target time period. The UE determines the time position of the first occasion of the second low-power signal based on the time offset parameter and the time resources of the first occasion of the first low-power signal. Moreover, the UE determines the time positions of other occasions of the second low-power signal within the specific time period based on the time position of the first occasion of the second low-power signal.

[0118] In another implementation, the time offset parameter may be the time offset between the first first-candidate occasion of the first low-power signal corresponding to the same characteristic and the first second-candidate occasion of the second low-power signal within a target time period. Then, the terminal can determine the time position of the first second-candidate occasion of the second low-power signal based on the time resource information of the first first-candidate occasion of the first low-power signal, and then determine the time positions of other second-candidate occasions of the second low-power signal corresponding to the same characteristic within the target time period, where the other second-candidate occasions are the second-candidate occasions of the second low-power signal in the target time period except the first second-candidate occasion.

[0119] For example, a network-side device configures a time offset parameter. The time offset parameter is the time offset between the first occasion of the first low-power signal corresponding to the same characteristic and the first occasion of the second low-power signal within a target time period. The UE determines the time position of the first occasion of the second low-power signal based on the time offset parameter and the time resources of the first occasion of the first low-power signal. Moreover, the UE determines the time positions of other occasions of the second low-power signal corresponding to the same characteristic within the specific time period based on the time position of the first occasion of the second low-power signal.

[0120] Optionally, the above same characteristic is the same spatial characteristic. For example, it satisfies the same spatial reception characteristic, such as QCL type-D, or satisfies the same Doppler and time delay parameters, such as QCL type-A.

[0121] In the above optional implementation, optionally, there are multiple time offset parameters, and each time offset parameter corresponds to a group of low-power signals that satisfy the same characteristic. For example, Figure 8As shown, the network-side device or protocol configures a time offset parameter for each group of low-power signals that meet the same characteristics. Alternatively, there is one time offset parameter, and one said time offset parameter corresponds to each group of low-power signals that meet the same characteristics. For example, as Figure 7 shown, the network-side device or protocol configures one time offset parameter, which is applicable to each group of low-power signals that meet the same characteristics.

[0122] It should be noted that although the N and L of LP-WUS and LP-SS are the same in Figure 7 and Figure 8 , in the embodiments of the present application, it is not limited that the numbers of N and L of the first low-power signal and the second low-power signal are the same, and the numbers of N and L of the first low-power signal and the second low-power signal may also be different.

[0123] In each implementation manner of the embodiments of the present application, the target time period may include one of the transmission period of the first low-power signal, the transmission period of the second low-power signal, the time period configured in the resource parameter, and the target time period, where the target time period is the least common multiple of the transmission period of the first low-power signal and the transmission period of the second low-power signal.

[0124] In an alternative implementation manner, the terminal may determine the indexes of each candidate occasion or each candidate occasion set of the target low-power signal within a time period based on at least one candidate occasion of the target low-power signal, where the time period includes one of the following: the reception time window of the target low-power signal, the transmission period of the target low-power signal.

[0125] For example, the terminal may assume that the occasion index corresponding to the i-th occasion within the reception time window of a target low-power signal or within one transmission period is i or i - 1. For example, if the value of occasionindex starts from 0, then the occasion index of the 1st occasion = 0. Or

[0126] alternatively, the terminal assumes that the occasion set index corresponding to the i-th candidate occasion set within the reception time window of a target low-power signal or within one transmission period is i or i - 1.

[0127] Optionally, the terminal may further determine the candidate occasion set to which each of the candidate occasions belongs based on the indexes of each of the candidate occasions.

[0128] Among them, for a group of occasions corresponding to an Occasion set i, the relationship between the occasion index of each occasion and the occasion set index i is predefined or can also be configured by the network-side device. Therefore, the UE can obtain the occasion set index where this occasion is located based on the occasion index.

[0129] For example, if the occasion index i belongs to occasion set j and (i mod L) = j, where i is the occasion index, j is the occasion set index, and L is the total number of occasion sets, or L is a QCL parameter (for example, L represents that there can be L different beams, or L is the number of low-power signals transmitted within a transmission period. For example, in Figure 5 and Figure 10 where L = 4 and N = 2.

[0130] Another example is that if the occasion index i belongs to occasion set j and floor(i / N) = j, where i is the occasion index, j is the occasion set index, and N is the total number of occasions in an occasion set. For example, in Figure 4 and Figure 9 where L = 4 and N = 2.

[0131] In an optional implementation manner, the terminal can determine the spatial characteristics of each of the target low-power signals detected at the at least one candidate occasion according to the target occasion of the detected target low-power signal, where the target occasion is one of the at least one candidate occasion.

[0132] For example, the UE can determine the index of the low-power signal according to the occasion index or occasion set index where the detected low-power signal is located. Alternatively, the index of the low-power signal can also be carried by the low-power signal. For example, the index is determined according to the sequence or payload of the low-power signal. Then, the spatial characteristics of the detected low-power signal are determined according to the index of the low-power signal.

[0133] For example, the protocol or network-side device configures the transmission period Tp of the target low-capability signal, the time offset Offset1, the reception time window length within one transmission period, the length of each occasion, and the time interval between occasions. The UE can calculate the positions of each occasion within the reception time window and the number of occasions based on the time window length, the length of each occasion, and the time interval between occasions.

[0134] For another example, the protocol or network-side device configures the transmission period Tp of the target low-capability signal, the time offset Offset1, the length of each occasion, the time interval between occasions, the number of occasions within one period, or the number of occasion sets within one occasion and the number of occasions within the set. The UE can calculate the positions of each occasion, the positions of occasion sets, and the number of occasions.

[0135] For another example, the protocol or network-side device configures the transmission period Tp of the target low-capability signal, the time offset Offset1, the length of each occasion, the time interval between occasions, the time interval between occasion sets, and the reception time window length, where one reception time window corresponds to one occasion set. The UE can calculate the positions of each occasion, the positions of occasion sets, and the number of occasions. For example, the protocol or network-side device configures Tp, offset1, the length of the occasion To, the interval of the occasion offset_i, the intervals between occasion sets as Offset_j1 and Offset_j2, and the reception time window lengths of occasion sets as Tset1, Tset2, and Tset3. The UE can calculate the position of the first reception time window of each transmission period based on Tp and offset1, and calculate the positions of the second and third time windows based on Offset_j1 and Offset_j2. Based on Tset1, Tset2, and Tset3, the length of each occasion, and the time interval between occasions, calculate the positions and numbers of occasions within each time window.

[0136] For another example, the protocol or network-side device configures the transmission period Tp of the target low-power signal, the time offset Offset1, the length of each occasion, the time interval between occasions, the time interval between occasion sets, and the number of occasions within each occasion set. The UE can deduce the positions of each occasion, the positions of occasion sets, and the number of occasions.

[0137] In the embodiments of the present application, when the terminal determines the spatial characteristics of each of the target low-power signals detected in the at least one candidate occasion, for at least two of the target low-power signals of the same type, for example, two LP-WUSs detected at different candidate occasions, the terminal may determine the spatial characteristics of the at least two detected target low-power signals according to the following Embodiment 1 to Embodiment 5.

[0138] Embodiment 1: The terminal determines that the target low-power signals corresponding to each target occasion in the same candidate occasion set satisfy the same spatial characteristics within a target time period, and the target low-power signals corresponding to the same candidate occasion set satisfy the same spatial characteristics in different target time periods. That is to say, the UE may assume that within a target time period of the target low-power signal, each occasion or the target low-power signals in each occasion corresponding to the same occasion set satisfy the same characteristics, and the UE may assume that the low-power signals corresponding to the same occasion set or the low-power signals in the same occasion set in different periods of the target low-power signal satisfy the same characteristics.

[0139] For example, there are multiple occasions within a signal period Tp of the low-power signal and the numbers of the occasions within each period Tp. Or, the numbers within each occasion set within a signal period Tp. For example, the total number of occasions O within a signal period Tp is 8, numbered 0 to O-1 (0 to 7). Assume that there are L = 4 occasion sets within a signal period Tp, and the occasion set numbers are 0 to L-1 (0 to 3). An occasion set has N = 2 occasions. Then according to Method A, the occasion index i belongs to occasion set j if (i mod L) = j. For example, as Figure 5 shown. Or, according to Method B, the occasion index i belongs to occasion set j if floor(i / N) = j, as Figure 4As shown. In an occasion within each signaling cycle, if they correspond to the same occasion set index, these occasions are considered to correspond to the same occasion set.

[0140] Furthermore, the UE can deduce the index of the candidate low-power signal or the index of the low-power signal through the occasion index or the occasion set index. For example, the index of the candidate low-power signal or the index of the low-power signal is the index of the occasion set, that is, the candidate LP-SS / LP-WUS index = i or the LP-SS / LP-WUS index = i of the LP-SS or LP-WUS sent in occasion set i. Another example is that the index of the candidate low-power signal or the index of the low-power signal is determined according to the occasion index. According to Method A, the candidate LP-SS / LP-WUS index of the LP-SS or LP-WUS sent in occasion index i = j if (i mod L) = j, or if floor(i / N) = j.

[0141] According to the above Embodiment 1, the low-power signals sent by the network-side device in any occasion within the same occasion set within one or more target time cycles need to satisfy the same characteristics. Correspondingly, the UE can assume that the low-power signals in any occasion within the same or different target time cycles corresponding to the same occasion set satisfy the same characteristics. As Figure 9 and Figure 10 shown, the target time cycle T can be the signaling cycle of the LP-SS, L = 4, N = 2. The LP-SS sent by the network-side device in occasion set i (i = 0, 1, 2, 3) in any cycle needs to satisfy the same spatial characteristics, such as using the same beam. The UE can assume that the LP-SS sent in occasion i within multiple cycles satisfies QCL type-D and / or QCL type-A.

[0142] Embodiment 2: The terminal determines that within one target time cycle, the target low-power signals corresponding to each target occasion within the same candidate occasion set satisfy the same spatial characteristics, and within different target time cycles, the target low-power signals corresponding to each target occasion within the same candidate occasion set do not satisfy the same spatial characteristics.

[0143] In this embodiment, the low-power signals sent by the network-side device in any occasion corresponding to the same occasion set within a target time period need to meet the same characteristics. In different target time periods, the low-power signals sent in the same occasion set do not need to meet the same characteristics.

[0144] Accordingly, the UE can assume that the low-power signals in any occasion corresponding to the same occasion set within the same target time period meet the same characteristics, and the low-power signals in any occasion corresponding to the same occasion set in different target time periods do not meet the same characteristics.

[0145] Compared with Embodiment 1, in Embodiment 2, the network-side device has greater scheduling flexibility, but it may increase the power consumption of the UE.

[0146] Such as Figure 11 and Figure 12 As shown, the target time period T is the signal period of the LP-SS, L = 4, N = 2. The LP-SS sent by the network-side device in the occasion set i (i = 0, 1, 2, 3) within a target time period needs to meet the same spatial characteristics, such as using the same beam. The UE can assume that the LP-SS sent in occasion i in multiple target time periods does not meet QCL type-D and / or QCL type-A. For example, for occasion set 0 in the first target time period and occasion set 0 in the second target time period, the network-side device sends using different beams, and the UE cannot assume that the LP-SS of these two occasion sets 0 in the two target time periods meets the same characteristics.

[0147] Embodiment 3, the terminal determines that the target low-power signals corresponding to each target occasion do not meet the same spatial characteristics in the same or different target time periods.

[0148] In this embodiment, the low-power signals sent by the network-side device in any two occasions do not need to meet the same characteristics. Accordingly, the UE considers that the low-power signals sent in any two occasions do not meet the same characteristics, as Figure 13 shown.

[0149] Embodiment 4: The terminal determines that target low-power signals with the same index satisfy the same spatial characteristics in the same or different target time periods, where the index of the target low-power signal is based on at least one of the following: the index of the target occasion, the index of the candidate occasion set to which the target occasion belongs, and the information carried in the target low-power signal.

[0150] In this embodiment, the spatial characteristics of the same type of target low-power signals are determined according to the index of the target low-power signal. The UE may assume that low-power signals corresponding to the same index of the same candidate low-power signal or the index of the low-power signal in the same or different target time periods satisfy the same characteristics. The index of the candidate low-power signal or the index of the low-power signal may be determined according to the occasion index or occasion set index, or according to the index configured in the resource configuration of the low-power signal, or determined by the index carried by the low-power signal. For example, it is determined by different sequences or load indications.

[0151] Embodiment 5: The terminal determines that target low-power signals with the same index satisfy the same spatial characteristics within one target time period, and target low-power signals with the same index do not satisfy the same characteristics in different target time periods, where the index of the target low-power signal is based on at least one of the following: the index of the target occasion, the index of the candidate occasion set to which the target occasion belongs, and the information carried in the target low-power signal.

[0152] In this embodiment, the spatial characteristics of multiple target low-power signals of the same type are determined according to the index of the target low-power signal. For example, the UE may assume that low-power signals corresponding to the same index of the same candidate low-power signal or the index of the low-power signal within the same target time period satisfy the same characteristics, and low-power signals corresponding to the same index of the same candidate low-power signal or the index of the low-power signal in different target time periods do not satisfy the same characteristics.

[0153] Optionally, the UE may assume that the network-side device sends the target low-power signal in only one occasion of each occasion set within one target time period.

[0154] Optionally, the UE may assume that the network-side device sends the target low-power signal in only one occasion of each occasion set within each target time period. Alternatively, the UE may assume that the network-side device sends the low-power signal in only one occasion of X occasion sets within each target time period, and the value of X may be different in each target time period.

[0155] If the transmission of the target low-power signal is based on repetition (number of repetitions = R, R > 1), in one implementation, R repetitions of a low-power signal are transmitted in R occasions in an occasion set. Optionally, N is an integer multiple of R. The R occasions corresponding to the R repetitions can be any R of the N occasions, as Figure 14 shown. Or determine the R occasions according to a predefined rule. For example, map to the adjacent R occasions, and the first occasion needs to satisfy occasion index (i mod R) = 0, as Figure 15 shown.

[0156] In the embodiments of the present application, when the terminal determines the spatial characteristics of each of the target low-power signals detected in the at least one candidate occasion, for at least two target low-power signals of different types detected within the same target time period or different target time periods, for example, LP-WUS and LP-SS detected at different candidate occasions, or LP-WUS and SSB detected at different candidate occasions, the terminal can determine the spatial characteristics of the at least two target low-power signals detected according to the following Embodiments 1 to 6.

[0157] Embodiment 1, the terminal determines that the first low-power signal and the second low-power signal corresponding to the target occasion in the same candidate occasion set satisfy the same spatial characteristics.

[0158] For example, the UE may consider that LP-SS and LP-WUS corresponding to the same occasion set within one or more target time periods satisfy the same characteristics.

[0159] For example, the network-side device needs to satisfy the same characteristics for the LP-WUS transmitted in the same occasion set within one or more target time periods, and the network-side device needs to satisfy the same characteristics for the LP-SS transmitted in the same occasion set within one or more target time periods. In addition, the characteristics of LP-SS and LP-WUS corresponding to an occasion set are the same. As Figure 16 shown, where the target time period is the LP-SS period.

[0160] For another example, the UE may assume that an SSB and an LP-WUS corresponding to the same occasion set satisfy the same characteristics.

[0161] Embodiment 2: The terminal determines that the first low-power signal corresponding to the target timing in the first candidate timing set and the second low-power signal corresponding to the target timing in the second candidate timing set satisfy the same spatial characteristics, where the index of the first candidate timing set and the index of the second candidate timing set satisfy a first predetermined relationship.

[0162] In this embodiment, if the number of occasion sets L1 in a signal period of an LP-SS and the number of occasion sets L2 in a signal period of an LP-SS are not equal, and if the occasion set i of the LP-SS and the occasion set j of the LP-WUS satisfy the first predetermined relationship, the UE may consider that the LP-SS corresponding to the occasion set i of the LP-SS and the LP-WUS corresponding to the occasion set j of the LP-WUS in one or more specific periods satisfy the same characteristics. For example, if L1 / L2 = A, the first predetermined relationship may be: i and j satisfy the relationship floor(j / A) = i.

[0163] Alternatively, the UE may assume that an SSB corresponding to the occasion set i and an LP-WUS corresponding to the occasion set j satisfy the same characteristics if the occasion set i and the occasion set j satisfy a second predetermined relationship. For example, the second predetermined relationship is (i mod M) = j, or (j mod M) = i, where M is the ratio of the number of SSB occasion sets to the number of LP-WUS occasion sets or is configured by the network-side device. Another example is that the specific relationship is floor(i / M) = j, or floor(j / M) = i.

[0164] Embodiment 3: The terminal determines that the first low-power signal and the second low-power signal corresponding to the target timing satisfying the second predetermined relationship satisfy the same characteristics.

[0165] For example, the UE may consider that the LP-SS corresponding to the occasion index i of the LP-SS and the LP-WUS corresponding to the occasion index j of the LP-WUS in one or more target time periods satisfy the same characteristics, where i and j satisfy a second predetermined relationship. For example, the second predetermined relationship is (i mod L1) = (j mod L2), where L1 is the number of LP-SSs in one LP-SS period, and L2 is the number of LP-WUSs in one LP-WUS period. Another example is that the second predetermined relationship is floor(i / N1) = floor(j / N2), where N1 is the number of occasions of LP-SSs in one occasion set, and N2 is the number of occasions of LP-WUSs in one occasion set.

[0166] Another example is that the UE may consider that the LP-SS corresponding to the occasion index i of the LP-SS and the LP-WUS corresponding to the occasion index j of the LP-WUS in one or more target time periods satisfy the same characteristics, where i and j satisfy a second predetermined relationship, and the LP-SSs and LP-WUSs in different target time periods do not satisfy the same characteristics. As Figure 17 shown.

[0167] Another example is that the UE may assume that an SSB corresponding to the occasion index i and an LP-WUS corresponding to the occasion index j satisfy the same characteristics if the occasion set i and the occasion set j satisfy a second predetermined relationship. For example, the second predetermined relationship is (i mod L1) = (j mod L2), where L1 is the number of SSBs, for example, the number of SSBs determined based on ssb-PositionsInBurst, or the number of SSBs that the LR to be measured configured by the base station, and L2 is the number of LP-WUSs in one LP-WUS period. Another example is that the second predetermined relationship is floor(i / N1) = floor(j / N2), where N1 is the number of occasions of SSBs in one occasion set, and N2 is the number of occasions of LP-WUSs in one occasion set.

[0168] In Embodiment 4, the terminal determines that the first low-power signal and the second low-power signal with the same index satisfy the same spatial characteristics.

[0169] For example, the UE may assume that the LP-SS and LP-WUS corresponding to the same candidate LP-SS and LP-WUS indices, or the LP-SS and LP-WUS with the same LP-SS and LP-WUS indices, in the same or different target time periods satisfy the same characteristics.

[0170] Alternatively, the UE may also assume that the LP-SS and LP-WUS corresponding to the same candidate LP-SS and LP-WUS indices or the LP-SS and LP-WUS with the same LP-SS and LP-WUS indices in the same specific period satisfy the same characteristics, and the LP-SS and LP-WUS in different periods do not satisfy the same characteristics.

[0171] Among them, the candidate LP-SS and LP-WUS indices or the LP-SS and LP-WUS indices can be determined according to the corresponding occasion index or occasion set index, or according to the indices configured in the resource configuration of the LP-SS and LP-WUS, or determined by the indices carried by the LP-SS and LP-WUS. For example, through different sequences or payload indications.

[0172] For example, the UE may assume that an SSB and an LP-WUS corresponding to the same index satisfy the same characteristics.

[0173] Embodiment 5: The terminal determines that the first low-power signal and the second low-power signal whose indices satisfy the third predetermined relationship satisfy the same spatial characteristics.

[0174] For example, the UE may consider that the SSB and LP-WUS in one or more target time periods satisfy the same characteristics if the SSB index i or candidate SSB index i and the LP-WUS occasion set j or LP-WUS occasion index j satisfy the third predetermined relationship.

[0175] For example, the third predetermined relationship is (i mod A) = j, or (j mod A) = i, where M is predefined or configured by the base station. Another example is that the third predetermined relationship is floor(i / M) = j, or floor(j / M) = i.

[0176] Embodiment 6: The terminal determines that the second low-power signal that is the reference signal of the first low-power signal satisfies the same spatial characteristics as the first low-power signal.

[0177] For example, the UE may consider that an SSB and an LP-WUS satisfy the same characteristics if this SSB is configured as the reference signal for the characteristics of the LP-WUS.

[0178] For another example, the UE may consider that an LP-SS and an LP-WUS satisfy the same characteristics if the LP-SS is configured as a reference signal for the characteristics of the LP-WUS.

[0179] In one or more alternative implementations, the method may further include: the terminal combines multiple target low-power signals having the same spatial characteristics. For example, the terminal may combine the same type of target low-power signals having the same spatial characteristics to obtain a measurement result of a beam. Alternatively, the terminal may also combine different types of target low-power signals having the same spatial characteristics. For example, it may combine the measurement results of an LP-SS and an LP-WUS having the same spatial characteristics, or combine the measurement results of an LP-SS and an SSB based on an LP-WUR measurement and having the same spatial characteristics.

[0180] Through the above technical solutions provided by the embodiments of the present application, it is possible to support the network-side device to send LP-SS / LP-WUS using multiple beams, implement beam sweeping, and at the same time provide a certain degree of scheduling flexibility, reducing the impact on the transmission of other NR signals. And it can support the UE to receive LP-WUS based on the synchronization information and beam information of the LP-SS, improving the reception performance and reducing the power consumption.
