[0004] The New Radio (NR) introduces a low-power wake-up module / receiver and a low-power wake-up signal.

[0050] In order to better understand the technical solutions provided by this application, we first introduce the relevant technologies involved in this application.

[0051] 1. LP-SS and LP-WUR

[0052] 3GPP will begin research on the Low Power Wake-Up Receiver (LP WUR) / wake-up signal (WUS) in mobile cellular systems in Rel-18. The basic operating principle of the LP WUR is as follows: the receiving end includes a first module and a second module. The first module is the main communication module, used to receive and send communication data transmitted by the transmitting end. The second module is a low-power module, used to receive the low-power wake-up signal (LP-WUS) and low-power synchronization signal (LP-SS) sent by the transmitting end. The low-power wake-up signal is used to wake up the receiving end's main communication module, and the low-power synchronization signal is used to provide time reference information and other information for receiving the low-power wake-up signal, such as for performing RRM measurements of the serving cell and providing wake-up link management. As shown in Figure 2, 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, the second module detects the wake-up signal sent by the transmitting end, and the wake-up signal contains terminal information. The second module triggers the first module to switch from the off state to the active state, allowing it to receive and send data. The second module can be turned on continuously or discontinuously, and can receive a low-power wake-up signal and a low-power synchronization signal when the second module is turned on.

[0053] 2. Beam-based transmission in NR systems

[0054] 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 by 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 DMRS of the PBCH and the PBCH payload. SSBs can be sent periodically, and all SSBs indicated by ssb-PositionsInBurst are sent in one period. All SSBs can be called a group of SSBs, or an SSB burst. The UE assumes that different SSB indices do not satisfy the Quasi Co-location (QCL) relationship, and SSBs with the same SSB index satisfy the QCL relationship and can be merged. For example, SSBs with the same SSB index in different periods are merged to obtain the measurement results of the same beam.

[0055] An SSB burst can be located in the first or second half of a frame. Within a half frame, the time position of an SSB burst is predefined by the standard.

[0056] In the licensed band, an SSB has only one occasion within a cycle, and the time position is predefined by the standard. In the unlicensed band, to reduce the impact of listen-before-talk (LBT), an SSB can have N occasions within a cycle, N ≥ 1, and the time positions of the N occasions are predefined by the standard. The base station can send this SSB at any position among the N occasions. The time relationship between the multiple occasions of SSBs with different SSB indices is: the first occasion of each SSB index is arranged in sequence, followed by the second occasion of each SSB index, and so on. Within each cycle, the occasion positions of all SSBs and the correspondence between SSB indices and occasions are the same. For example, the first 8 occasions of each cycle correspond to the first occasions of SSBs 1 to 8, and the last 8 occasions of each cycle correspond to the second occasions of SSBs 1 to 8. The UE assumes that 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, SSBs with the same SSB index in different periods are merged to obtain the measurement results of the same beam.

[0057] However, in the traditional NR system, the occasion of each SSB is predefined by the standard. Within each period, the position of the occasion, the correspondence between the occasion and the SSB index, and the correspondence between the beam of each SSB index are unchanged. And each occasion is located in the same or adjacent time slot. Each SSB index is indicated by DMRS, or by DMRS+PBCH payload. Other signals in the NR system, such as the Channel State Information Reference Signal (CSI-RS), can be configured with the SSB index of the QCL reference signal SSB if the base station uses the same beam to send.

[0058] For low-power signal transmission, the traditional SSB occasion cannot meet the requirements. For example, the number of orthogonal frequency division multiplex (OFDM) symbols occupied by a low-power signal is usually greater than that of SSB. One SSB occasion cannot carry a low-power signal, and the position of the SSB occasion is relatively fixed. The SSB index sent within the occasion and the beam corresponding to the SSB are relatively fixed, which is not flexible enough and may have a greater impact on the transmission of other NR signals. In addition, since the low-power signal can carry limited information, for example, the LP-SS sequence-based signal may not be able to carry the 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. In addition, it is also impossible to reuse the method of configuring the SSB index as the QCL reference signal information to determine the QCL relationship between LP-SS and LP-WUS.

[0059] Therefore, the related art does not provide a solution for how a terminal receives low-power signals in the case of multi-beam transmission. To address this problem, an embodiment of the present application provides a low-power signal reception solution.

[0060] The following describes in detail the low-power signal receiving solution provided by the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0061] FIG3 shows a flow chart of a method for receiving a low-power signal according to an embodiment of the present application. The 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 shown in FIG3 , the method can include the following steps.

[0062] S310: The terminal determines at least one candidate timing for a target low power consumption signal according to resource parameters configured for the target low power consumption signal.

[0063] In an embodiment of the present application, the terminal can determine at least one candidate occasion (occasion) of the target low-power signal based on 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 parameters included in the resource parameters may be configured by the network side device or the protocol, or part of the parameters included in the resource parameters may be configured by the network side device, and the other part of the parameters may be 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. 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.

[0064] For example, the network-side device configures LP-SS / LP-WUS resource parameters for the UE. Based on the LP-SS / LP-WUS resource parameters configured by the network-side device for the UE and the standard predefined resource parameters, the UE determines the LP-SS / LP-WUS resources, for example, determining the candidate locations (occasions) of the LP-SS / LP-WUS and the time domain, frequency domain, code domain, spatial domain information, and channel structure of the LP-SS / LP-WUS transmitted in each candidate location. The time domain, frequency domain, code domain, and spatial domain information may include: spatial transmission characteristics, spatial reception characteristics, Doppler characteristics, and time delay characteristics.

[0065] In an optional implementation, the resource parameters include but are not limited to the sending period of the target low-power signal, the length of the receiving time window of the target low-power signal, the candidate timing information contained in the receiving time window of the target low-power signal, the candidate timing information contained in a sending period, the spatial characteristics corresponding to each candidate timing and at least one of the number of repetitions of the target low-power signal.

[0066] Among them, the sending period of the target low-power signal is used to indicate the sending period of the target low-power signal. The length of the receiving time window of the target low-power signal is used to indicate the length of the receiving time window of the target low-power signal. The candidate timing information contained in the receiving time window of the target low-power signal is used to indicate the candidate timing contained in the receiving window of the target low-power signal. The candidate timing information contained in a sending period is used to indicate the candidate timing contained in the sending period of the target low-power signal. The spatial characteristics corresponding to each candidate timing are used to determine the spatial characteristics of the target low-power signal sent at each candidate timing. The number of repetitions of the target low-power signal is used to indicate the number of times the target low-power signal is repeatedly sent.

[0067] Optionally, the candidate opportunity information contained in the receiving time window of the above-mentioned target low-power signal or the candidate opportunity information contained in a sending cycle includes but is not limited to the time length of a candidate opportunity, the time interval between two adjacent candidate opportunities, the time interval between two adjacent candidate opportunity sets (occasion sets), the number of candidate opportunities, the number of candidate opportunity sets, and at least one of the number of candidate opportunities in a candidate opportunity set.

[0068] Optionally, the number of candidate opportunities in each candidate opportunity set is the same.

[0069] Optionally, the number of candidate opportunities in each candidate opportunity set may be different. For example, the number of candidate opportunities in each candidate opportunity set may be different due to the length of the receiving time window. Alternatively, the network device may configure the number of candidate opportunities for each candidate opportunity set.

[0070] Optionally, a time interval may be configured in the above resource parameters, where the time interval is the time interval between candidate opportunities within a target time period.

[0071] For example, in Figure 4, Offset_i1, Offset_i2, Offset_i3, Offset_i4, Offset_j1, Offset_j2, and Offset_j3 have the same value, and the network-side device indicates or the protocol predefines a single value. In Figure 5, Offset_j1, Offset_j2, Offset_j3, Offset_j4, Offset_j5, Offset_j6, and Offset_i have the same value, and the network node indicates only one value.

[0072] The terminal may determine the time resource of each occasion according to the time resource of the first occasion of each cycle, the time interval, and the number of candidate opportunities.

[0073] Optionally, two time intervals may be configured in the above resource parameters, one time interval being the time interval between each candidate occasion in a candidate occasion set, and the other time interval being the time interval between each candidate occasion set.

[0074] For example, in Figure 4, Offset_i1, Offset_i2, Offset_i3, and Offset_i4 are identical, representing the time intervals between candidate occasions within a candidate occasion set. Offset_j1, Offset_j2, and Offset_j3 are identical, representing the time intervals between candidate occasion sets. In Figure 5, Offset_i represents the time interval between candidate occasions within a candidate occasion set. Offset_j1, Offset_j2, Offset_j3, Offset_j4, Offset_j5, and Offset_j6 are identical, representing the time intervals between candidate occasion sets.

[0075] In FIG6 , Offset_i1, Offset_i2, Offset_i3, Offset_i4, Offset_i5, and Offset_i6 are the same, and are the time intervals between candidate occasions in a candidate occasion set. Offset_j is the time interval between candidate occasion sets.

[0076] The terminal may determine the time resource of each occasion according to the time resource of the first occasion of each cycle, the two time intervals and the number of occasions.

[0077] Optionally, multiple time intervals can be configured in the above resource parameters. One time interval is the interval between each occurrence within an occurrence set, and the other time intervals are the intervals between each occurrence set. Each occurrence set may not be exactly the same. The terminal can determine the number of occurrence sets based on the number of time intervals, or the number of occurrence sets can be predefined by the protocol or configured by the network device.

[0078] The terminal may determine the time resource of each occasion according to the time resource of the first occasion of each cycle, the multiple time intervals and the number of occasions.

[0079] Optionally, the spatial characteristics corresponding to each candidate opportunity may include at least one of the following 1) to 6).

[0080] 1) Within the same target time period, the target low-power signals corresponding to each candidate opportunity in the same candidate opportunity set have the same spatial characteristics. In other words, each occasion in an occasion set corresponds to the same characteristics, such as the same spatial reception characteristics or the same Doppler and time delay parameters.

[0081] As shown in Figures 4 and 5, assuming that the number of LP-SSs sent by the network device in a cycle is L = 4, and the number of occasions for each LP-SS is N = 2, the total number of occasions is O = 8. Therefore, the N occasions of an LP-SS constitute an occasion set. Different LP-SSs correspond to different occasion sets. Of the N occasions of an LP-SS, the network device can send the LP-SS in only one occasion.

[0082] Network-side devices can configure reference signals, such as LP-SS or SSB, for LP-WUS. The reference signals are assumed to have the same spatial reception characteristics as the LP-WUS. For example, if the network-side device configures SSB1, SSB2, SSB3, and SSB4 as reference signals, these four SSBs represent the four occasions of the LP-WUS, and the LP-WUS has the same spatial reception characteristics.

[0083] 2) Within the same target time period, the target low-power signals corresponding to the candidate occasions in the same candidate occasion set have different spatial characteristics. In other words, each occasion in an occasion set may correspond to a different characteristic.

[0084] For example, as shown in Figure 5, assuming that within a period, the network device transmits L = 4 LP-SSs, and each LP-SS has N = 2 occasions, the total number of occasions is O = 8. The network device or protocol can configure two occasion sets, with the occasions in each set relatively concentrated in time. The network device transmits only two LP-SSs in each of the eight occasions. For example, two LP-SSs may be transmitted in only one occasion, or only one LP-SS may be transmitted in each occasion.

[0085] 3) Within the same target time period, the target low-power signals corresponding to the candidate timings whose candidate timing positions or candidate timing indexes satisfy a predefined relationship have the same spatial characteristics.

[0086] Among them, the terminal may assume that the opportunity index (occasion index) corresponding to the i-th occasion within the receiving time window of a target low-power signal or within a cycle is i or i-1. For example, if the value of the occasion index starts from 0, the occasion index of the first occasion = 0. Alternatively, the terminal assumes that the candidate opportunity set index (occasion set index) corresponding to the i-th candidate opportunity set (occasion set) within the receiving time window of a target low-power signal or within a cycle is i or i-1. 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 it can also be configured by the network side device.

[0087] For example, occasion index i belongs to occasion set j if (i mod L) = j, or occasion index i belongs to occasion set j if floor(i / N) = j, where L and N are configured or predefined by the standard. 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, configuring LP-SS or SSB as a reference signal for LP-WUS, and assuming that the reference signal has the same spatial reception characteristics as the LP-WUS.

[0088] 4) The target low-power signals corresponding to each candidate opportunity within the same target time period have the same spatial characteristics. For example, the network-side device can configure a reference signal that has the same spatial characteristics as the LP-WUS corresponding to each candidate LP-WUS opportunity.

[0089] 5) Within different target time periods, the target low-power signals corresponding to the candidate timings in the same candidate timing set have the same spatial characteristics.

[0090] Among them, 5) can be combined with 1), so that within the same or different target time periods, the target low-power signals corresponding to the candidate timings in the same candidate timing set have the same spatial characteristics.

[0091] 6) In different target time periods, the target low-power signals corresponding to the candidate timings in the same candidate timing set do not have the same spatial characteristics.

[0092] Among them, 6) can be combined with 1), so that within the same target time period, the target low-power signals at each candidate opportunity in the same candidate opportunity set meet the same spatial characteristics. Within different target time periods, the target low-power signals at each candidate opportunity in the same candidate opportunity set do not meet the same spatial characteristics.

[0093] 7) In different target time periods, target low power consumption signals corresponding to respective candidate timings in two candidate timing sets that satisfy the first predetermined relationship in different candidate timing sets have the same spatial characteristics.

[0094] Among them, 7) can be combined with 3), so that within the same or different target time periods, the target low power consumption signals corresponding to the respective candidate timings in two candidate timing sets that satisfy the first predetermined relationship in different candidate timing sets have the same spatial characteristics.

[0095] 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 at the candidate opportunities in occasion set i and occasion set j satisfy the same spatial characteristics. L1 can be the number of signals within one transmission cycle of the target low-power signal corresponding to occasion set i, and L2 is the number of signals within one transmission cycle of the target low-power signal corresponding to occasion set j.

[0096] In an optional implementation, the spatial characteristics of the target low-power signal can be the same spatial reception characteristics. The network side device can configure a reference signal, for example, configuring LP-SS or SSB as a reference signal for LP-WUS, and assuming that the reference signal has the same spatial reception characteristics as LP-WUS.

[0097] Optionally, the configured reference signal information includes a signal type, such as LP-SS or SSB. The configured reference signal information may also include a signal index, an occasion set index, an occasion index, or one of a resource configuration index, such as an LP-SS index, an SSB index, or an LP-SS occasion index.

[0098] The configured reference signal information can include only one reference signal or a group of reference signals. When configured as a group of reference signals, each reference signal can be considered to be the reference signal of each occasion set in sequence. If the number of occasion sets L and the number of configured reference signals are different, the relationship between each reference signal and each occasion set can be determined based on 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 corresponds to a reference signal.

[0099] If the reference signal information is not configured, it can be understood that there is no reference signal, or the reference signal is determined according to a predefined rule, for example, the SSB indicated in ssb-PositionsInBurst is the reference signal.

[0100] When LP-WUR receives an 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 based on the time information of the main receiver (MR) and the time position corresponding to the SSB index.

[0101] In an optional implementation, the resource parameters configured by the network-side device or protocol may include multiple sets of resource parameters, and within a target time period, the spatial characteristics corresponding to each of the candidate opportunities satisfy one of the following 1) to 3).

[0102] 1) The target low-power signals corresponding to the candidate opportunities configured in a set of resource parameters have the same signal characteristics. In other words, the target low-power signals detected at the candidate opportunities configured in a set of resource parameters have the same signal characteristics.

[0103] 2) The target low-power signals corresponding to the candidate timings whose candidate timing positions or candidate timing indices satisfy a predefined relationship among the candidate timings configured in a set of resource parameters have the same spatial characteristics. In other words, the target low-power signals detected at multiple candidate timings whose candidate timing positions or candidate timing indices satisfy a predefined relationship among the candidate timings configured in a segment of resource parameters have the same signal characteristics.

[0104] 3) A set of resource parameters includes multiple candidate opportunity sets, and the target low-power signals corresponding to the candidate opportunities in the same candidate opportunity set have the same signal characteristics. In other words, a set of resource parameters includes multiple candidate opportunity sets, and the target low-power signals detected at the candidate opportunities in the same candidate opportunity set have the same signal characteristics.

[0105] For example, the network side device configures one or more sets of LP-SS resource parameters, or one or more sets of LP-WUS resource parameters, where each occasion within a set of resources corresponds to the same characteristics, such as the same spatial reception characteristics or satisfies the same Doppler and time delay parameters.

[0106] For example, the network-side device configures 4 sets of LP-WUS resource parameters, and the corresponding LP-WUS resources in 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 has the same characteristics as the LP-WUS. In this example, it can be considered that there is no occasion set, or that one set of LP-WUS corresponds to one occasion set, and each occasion in this occasion set corresponds to the same characteristics. Alternatively, as shown in Figures 3 to 5, multiple occasion sets represent multiple receiving time windows.

[0107] For example, a network-side device configures a set of LP-SS resource parameters and a set of LP-WUS resource parameters. Within each set of resource parameters, multiple occasion sets are configured. Each occasion within each occasion set corresponds to the same characteristics, while different occasion sets can correspond to different characteristics, such as different spatial reception characteristics or different Doppler and time delay parameters.

[0108] S312: The terminal detects the target low power consumption signal sent by the network side device in the at least one candidate opportunity.

[0109] After determining at least one candidate timing for the target low power signal, the terminal can determine that the network side device may send the target low power signal at the at least one candidate timing. Therefore, the terminal detects the target low power signal sent by the network side device at the at least one candidate timing.

[0110] S314: The terminal determines the spatial characteristics of each detected target low-power signal according to the detected target low-power signal, wherein the spatial characteristics include at least one of the following: spatial reception characteristics, Doppler delay parameters, and time delay parameters.

[0111] In an embodiment of the present application, the terminal can determine the index of each candidate opportunity, the index of each candidate opportunity set, and at least one of the indexes of each target low-power signal based on the above-mentioned resource parameters. Based on at least one of the index of the candidate opportunity where the detected target low-power signal is located, the index of the candidate opportunity set, and the index of the target low-power signal, the terminal can determine the spatial characteristics of the detected target low-power signal.

[0112] In an embodiment of the present application, after the terminal detects the target low-power signal at one or more target opportunities in the at least one candidate opportunity, the terminal can determine the spatial characteristics of each detected target low-power signal based on each detected target low-power signal. This allows the terminal to detect the target low-power signal sent by the network-side device at at least one candidate opportunity based on the resource parameters configured by the network-side device or the protocol, and determine the spatial characteristics of each detected target low-power signal to achieve reception of the low-power signal.

[0113] In an optional implementation, 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, the target low-power signal may include different types of low-power signals. For example, the target low-power signal may include at least one of LP-WUS, LP-SS, and SSB. For example, for LP-WUR based on OFDM, the first low-power signal and the second low-power signal may be LP-WUS and SSB, respectively. For LP-WUR based on OOK, the first low-power signal and the second low-power signal may be LP-WUS and LP-SS, respectively.

[0114] In an optional implementation, the resource parameters may include resource parameters configured for the first low-power signal and resource parameters configured for the second low-power signal.

[0115] 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 for the first low-power signal based on the resource parameters configured for the first low-power signal, and determines at least one candidate timing for the second low-power signal based on the resource parameters configured for the second low-power signal. For example, the protocol or network-side device may configure the resource parameters for LP-SS and LP-WUS, respectively. The terminal determines the resources for LP-SS and LP-WUS, respectively, based on the parameters of LP-SS and LP-WUS.

[0116] Alternatively, the resource parameters configured for the first low-power signal and the resource parameters configured for the second low-power signal may be dependent on each other. 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 parameters 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 parameters.

[0117] 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 parameters of the second low-power signal relative to the first low-power signal resource. The terminal determines the resource of the first low-power signal based on the parameters of the first low-power signal, and determines the resource of the first low-power signal based on the parameters of the first low-power signal and the parameters of the second low-power signal relative to the first low-power signal resource. The first low-power signal may be LP-SS and the second low-power signal may be LP-WUS. Alternatively, the first low-power signal may be LP-WUS and the second low-power signal may be LP-SS.

[0118] 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. The terminal may then determine the time position of the first second candidate timing of the second low-power signal based on the time resource information of the first first candidate timing of the first low-power signal, and then determine the time position of other second candidate timings of the second low-power signal in the target time period based on the time position of the first second candidate timing of the second low-power signal, wherein the other second candidate timings are the second candidate timings of the second low-power signal in the target time period other than the first second candidate timing.

[0119] For example, the network-side device configures a time offset parameter, which may be a time offset between a first candidate position (occasion) of the first low-power signal and a 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 resource of the first occasion of the first low-power signal. And 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.

[0120] In another implementation, the time offset parameter can be the time offset between the first first candidate timing of the first low-power signal corresponding to the same characteristics and the first second candidate timing of the second low-power signal within a target time period. The terminal can determine the time position of the first second candidate timing of the second low-power signal based on the time resource information of the first first candidate timing of the first low-power signal, and then determine the time position of other second candidate timings of the second low-power signal corresponding to the same characteristics within the target time period based on the time position of the first second candidate timing of the second low-power signal, wherein the other second candidate timings are the second candidate timings of the second low-power signal in the target time period except the first second candidate timing.

[0121] For example, the network-side device configures a time offset parameter, which is the time offset between the first occasion of the first low-power signal and the first occasion of the second low-power signal corresponding to the same characteristics within the 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 resource of the first occasion of the first low-power signal. And the UE determines the time positions of other occasions of the second low-power signal corresponding to the same characteristics within the specific time period based on the time position of the first occasion of the second low-power signal.

[0122] Optionally, the above-mentioned same characteristics are the same spatial characteristics, for example, satisfying the same spatial reception characteristics, such as QCL type-D, or satisfying the same Doppler and time delay parameters, such as QCL type-A.

[0123] In the above optional implementation, optionally, there are multiple time offset parameters, each of which corresponds to a group of low-power signals that meet the same characteristics. For example, as shown in Figure 8, 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 time offset parameter corresponds to each group of low-power signals that meet the same characteristics. For example, as shown in Figure 7, 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.

[0124] It should be noted that although N and L of LP-WUS and LP-SS are the same in Figures 7 and 8, the embodiment of the present application does not limit the number of N and L of the first low-power signal and the second low-power signal to be the same, and the number of N and L of the first low-power signal and the second low-power signal may also be different.

[0125] The target time period described in various implementation methods of the embodiments of the present application may include a transmission period of a first low-power signal, a transmission period of a second low-power signal, a time period configured in the resource parameters, and one of target time periods, wherein 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.

[0126] In an optional implementation, the terminal can determine the indexes of each candidate timing or each candidate timing set of the target low power signal within a time period based on at least one candidate timing of the target low power signal, wherein the time period includes one of the following: the receiving time window of the target low power signal, the sending period of the target low power signal.

[0127] For example, the terminal may assume that the opportunity index (occasion index) corresponding to the i-th occasion within a reception time window of a target low-power signal or within a transmission cycle is i or i-1. For example, if the value of the occasion index starts from 0, the occasion index of the first occasion = 0. Alternatively, the terminal assumes that the candidate opportunity set index (occasion set index) corresponding to the i-th candidate opportunity set (occasion set) within a reception time window of a target low-power signal or within a transmission cycle is i or i-1.

[0128] Optionally, the terminal may further determine the candidate opportunity set to which each candidate opportunity belongs based on an index of each candidate opportunity.

[0129] An Occasion set i corresponds to a set of occasions. The relationship between the occurrence index of each occurrence and the occurrence set index i is predefined or can be configured by the network side device. Therefore, the UE can obtain the occurrence set index of this occurrence based on the occurrence index.

[0130] For example, occasion index i belongs to occasion set j if (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 indicates that there can be L different beams, or L is the number of low-power signals sent in one transmission cycle). For example, in Figures 5 and 10, L = 4 and N = 2.

[0131] For another example, if occurrence index i belongs to occurrence set j, floor(i / N)=j, where i is the occurrence index, j is the occurrence set index, and N is the total number of occurrences in an occurrence set. For example, in Figures 4 and 9, L=4 and N=2.

[0132] In an optional implementation, the terminal may determine the spatial characteristics of each target low power signal detected in the at least one candidate opportunity based on the target opportunity for detecting the target low power signal, wherein the target opportunity is one of the at least one candidate opportunity.

[0133] For example, the UE may determine the index of the low-power signal based on the occasion index or occasion set index of the detected low-power signal. Alternatively, the index of the low-power signal may be carried by the low-power signal, for example, by determining the index based on the sequence or payload of the low-power signal. The spatial characteristics of the detected low-power signal are then determined based on the index of the low-power signal.

[0134] For example, the protocol or network-side equipment configures the target low-function signal transmission period Tp, time offset Offset1, the length of the receiving time window within a transmission period, the length of each occurrence, and the interval between occurrences. The UE can calculate the position of each occurrence within the receiving time window and the number of occurrences based on the time window length, the length of each occurrence, and the interval between occurrences.

[0135] For example, the protocol or network-side equipment configures the target low-function signal transmission period Tp, time offset Offset1, the length of each occurrence, the time interval between occurrences, the number of occurrences within a period, or the number of occurrence sets within an occurrence and the number of occurrences within a set. The UE can calculate the location of each occurrence, the location of the occurrence set, and the number of occurrences.

[0136] For another example, the protocol or network-side device configures the target low-function signal transmission period Tp, time offset Offset1, the length of each occasion, the time interval between occasions, the time interval between occasion sets, and the length of the receive time window, where one receive time window corresponds to one occasion set. The UE can calculate the position of each occasion, the position of each occasion set, and the number of occasions. For example, the network-side device configures Tp, offset1, the length of each occasion To, the interval between occasions offset_i, the intervals between occasion sets Offset_j1 and Offset_j2, and the receive time window lengths of each occasion set Tset1, Tset2, and Tset3. The UE can calculate the position of the first receive time window in each transmission period based on Tp and offset1, and 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, the UE can calculate the position and number of occurrences within each time window.

[0137] For example, the protocol or network-side equipment configures the target low-function signal transmission period Tp, time offset Offset1, the length of each occurrence, the interval between occurrences, the interval between occurrence sets, and the number of occurrences in each occurrence set. The UE can then calculate the location of each occurrence, the location of the occurrence set, and the number of occurrences.

[0138] In an embodiment 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 opportunity, for at least two target low-power signals of the same type, for example, two LP-WUS detected at different candidate opportunities, the terminal can determine the spatial characteristics of the at least two detected target low-power signals according to the following implementation modes one to five.

[0139] In the first embodiment, the terminal determines that within a target time period, the target low-power signals corresponding to the respective target opportunities in the same candidate opportunity set satisfy the same spatial characteristics, and in different target time periods, the target low-power signals corresponding to the respective target opportunities in the same candidate opportunity set satisfy the same spatial characteristics. That is, the UE may assume that within a target time period of the target low-power signal, the target low-power signals corresponding to the respective occasions in the same occasion set or in each occasion satisfy the same characteristics, and the UE may assume that the low-power signals corresponding to the same occasion set or in the same occasion set in different periods of the target low-power signal satisfy the same characteristics.

[0140] For example, there are multiple occurrences within a signal period Tp of a low-power signal and the occurrences are numbered within each period Tp. Or, each occurrence set within a signal period Tp is numbered. For example, the total number of occurrences within a signal period Tp is O=8, numbered 0~O-1 (0~7). Assume that there are L=4 occurrence sets within a signal period Tp, and the occurrence sets are numbered 0~L-1 (0~3). An occurrence set has N=2 occurrences. Then, according to method A, occurrence index i belongs to occurrence set j if (i mod L)=j, for example, as shown in Figure 5. Or, according to method B, occurrence index i belongs to occurrence set j if floor(i / N)=j, as shown in Figure 4. If the occurrences in each signal period correspond to the same occurrence set index, then these occurrences are considered to correspond to the same occurrence set.

[0141] Furthermore, the UE can calculate 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 LP-SS / LP-WUS index=i of the LP-SS or LP-WUS sent in occasion set i. For another example, 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=j of the LP-SS or LP-WUS sent in occasion index i is the candidate LP-SS / LP-WUS index=j, if (i mod L)=j, or if floor(i / N)=j.

[0142] According to the above-mentioned embodiment 1, the low-power signal sent by the network side device in any occasion corresponding to the same occasion set within one or more target time periods must meet the same characteristics. Accordingly, the UE may assume that the low-power signal in any occasion corresponding to the same occasion set within the same or different target time periods meets the same characteristics. As shown in Figures 9 and 10, the target time period T can be the signal period of the LP-SS, L=4, N=2. The LP-SS sent by the network side device in any period of occasion set i (i=0, 1, 2, 3) must meet the same spatial characteristics, such as using the same beam. The UE may assume that the LP-SS sent in occasion i in multiple periods meets QCL type-D and / or QCL type-A.

[0143] In the second implementation mode, the terminal determines that within a target time period, the target low-power signals corresponding to each target opportunity in the same candidate opportunity set satisfy the same spatial characteristics, and within different target time periods, the target low-power signals corresponding to each target opportunity in the same candidate opportunity set do not satisfy the same spatial characteristics.

[0144] In this embodiment, the low-power signals sent by the network-side device in any one of the occasions in the same occasion set within a target time period must meet the same characteristics. Low-power signals sent in the same occasion set within different target time periods may not meet the same characteristics.

[0145] Accordingly, the UE may assume that the low-power signals in any occasion corresponding to the same occasion set within the same target time period satisfy the same characteristics, and the low-power signals in any occasion corresponding to the same occasion set within different target time periods do not satisfy the same characteristics.

[0146] Compared with the first embodiment, the second embodiment has greater scheduling flexibility for the network side device, but may increase the power consumption of the UE.

[0147] As shown in Figures 11 and 12, the target time period T is the signal period of the LP-SS, where L=4 and N=2. The LP-SS sent by the network-side device in occasion set i (i=0, 1, 2, 3) within a target time period must meet the same spatial characteristics, for example, use the same beam. The UE may consider that the LP-SS sent in occasion i within multiple target time periods does not meet QCL type-D and / or QCL type-A. For example, the network-side device sends different beams for occasion set 0 of the first target time period and the second target time period. The UE cannot assume that the LP-SS of occasion set 0 of these two target time periods meet the same characteristics.

[0148] In a third embodiment, the terminal determines that, in the same or different target time periods, the target low power consumption signals corresponding to the respective target moments do not satisfy the same spatial characteristics.

[0149] 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 shown in Figure 13.

[0150] In the fourth embodiment, the terminal determines that in the same or different target time periods, a target low-power signal with the same index satisfies the same spatial characteristics, wherein the index of the target low-power signal is based on at least one of the following: the index of the target opportunity, the index of the candidate opportunity set to which the target opportunity belongs, and the information carried in the target low-power signal.

[0151] In this embodiment, the spatial characteristics of the target low-power signal of the same type are determined according to the index of the target low-power signal. The UE may assume that the low-power signals corresponding to the same candidate low-power signal index or the index of the low-power signal within the same or different target time periods meet 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 the occasion set index, or determined 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, through different sequences or load indications.

[0152] Implementation method five, the terminal determines that within a target time period, the target low-power signal with the same index satisfies the same spatial characteristics, and in different target time periods, the target low-power signal with the same index does not satisfy the same characteristics, wherein the index of the target low-power signal is based on at least one of the following: the index of the target opportunity, the index of the candidate opportunity set to which the target opportunity belongs, and the information carried in the target low-power signal.

[0153] 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 the low-power signals corresponding to the same candidate low-power signal index or the index of the low-power signal within the same target time period meet the same characteristics, and the low-power signals corresponding to the same candidate low-power signal index or the index of the low-power signal in different target time periods do not meet the same characteristics.

[0154] Optionally, the UE may consider that the network-side device sends the target low power consumption signal in only one occasion in each occasion set within a target time period.

[0155] Optionally, the UE may consider that the network-side device sends the target low-power signal in only one occasion in each occasion set within each target time period. Alternatively, the UE may consider that the network-side device sends the low-power signal in only one occasion in X occasion sets within each target time period, where the value of X may be different in each target time period.

[0156] If the target low-power signal is sent based on repetition (repetition count = R, R > 1), in one implementation, R repetitions of a low-power signal are sent in R occurrences in an occasion set. Optionally, N is an integer multiple of R. The R occurrences corresponding to the R repetitions can be any R of the N occurrences, as shown in Figure 14. Alternatively, the R occurrences can be determined according to a predefined rule, for example, mapped to R adjacent occurrences, and the first occurrence must satisfy the occurrence index (i mod R) = 0, as shown in Figure 15.

[0157] In an embodiment 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 opportunity, 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 opportunities, or LP-WUS and SSB detected at different candidate opportunities, the terminal can determine the spatial characteristics of the at least two detected target low-power signals according to the following implementation methods one to six.

[0158] In the first embodiment, the terminal determines that the first low power consumption signal and the second low power consumption signal in the same candidate opportunity set corresponding to the target opportunity satisfy the same spatial characteristics.

[0159] For example, the UE may consider that the LP-SS and LP-WUS corresponding to the same occasion set within one or more target time periods meet the same characteristics.

[0160] For example, the LP-WUS sent by the network device within one or more target time periods and corresponding to the same occasion set must meet the same characteristics, and the LP-SS sent by the network device within one or more target time periods and corresponding to the same occasion set must meet the same characteristics. Furthermore, the LP-SS and LP-WUS characteristics corresponding to the same occasion set are the same. As shown in Figure 16, the target time period is the LP-SS period.

[0161] For another example, the UE may assume that an SSB and an LP-WUS corresponding to the same occasion set satisfy the same characteristics.

[0162] In the second embodiment, the terminal determines that the first low-power signal of the corresponding target timing in the first candidate timing set and the second low-power signal of the corresponding target timing in the second candidate timing set satisfy the same spatial characteristics, wherein the index of the first candidate timing set and the index of the second candidate timing set satisfy a first predetermined relationship.

[0163] In this embodiment, if the number of occasion sets L1 within an LP-SS signal cycle is not equal to the number of occasion sets L2 within an LP-SS signal cycle, and if LP-SS occasion set i and LP-WUS occasion set j satisfy a first predetermined relationship, the UE may deem that the LP-SS corresponding to LP-SS occasion set i and the LP-WUS corresponding to LP-WUS occasion set j within one or more specific cycles satisfy the same characteristics. For example, if L1 / L2=A, then the first predetermined relationship may be: i and j satisfy the relationship floor(j / A)=i.

[0164] Alternatively, the UE may assume that an SSB corresponding to occasion set i and an LP-WUS corresponding to occasion set j satisfy the same characteristics if occasion set i and 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. For another example, the specific relationship is floor(i / M) = j, or floor(j / M) = i.

[0165] In a third embodiment, the terminal determines that the first low power consumption signal and the second low power consumption signal satisfy the same characteristics when the corresponding target timing satisfies the second predetermined relationship.

[0166] For example, the UE may consider that the LP-SS corresponding to the LP-SS occasion index i and the LP-WUS corresponding to the LP-WUS occasion index j 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 an LP-SS period, and L2 is the number of LP-WUSs in an LP-WUS period. For another example, the second predetermined relationship is floor(i / N1) = floor(j / N2), where N1 is the number of LP-SS occasions in an occasion set, and N2 is the number of LP-WUS occasions in an occasion set.

[0167] For another example, the UE may consider that an LP-SS corresponding to LP-SS occasion index i and an LP-WUS corresponding to LP-WUS occasion index j within one or more target time periods satisfy the same characteristic, where i and j satisfy a second predetermined relationship, and that LP-SSs and LP-WUSs in different target time periods do not satisfy the same characteristic, as shown in Figure 17 .

[0168] For another example, the UE may assume that an SSB corresponding to occasion index i and an LP-WUS corresponding to occasion index j satisfy the same characteristics if occasion set i and 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 to be measured by the LR configured by the base station, and L2 is the number of LP-WUSs within an LP-WUS period. For another example, the second predetermined relationship is floor(i / N1) = floor(j / N2), where N1 is the number of SSB occasions in an occasion set, and N2 is the number of LP-WUS occasions in an occasion set.

[0169] In a fourth embodiment, the terminal determines that the first low power consumption signal and the second low power consumption signal with the same index satisfy the same spatial characteristics.

[0170] For example, the UE may assume that the LP-SS and LP-WUS corresponding to the same candidate LP-SS and LP-WUS indexes within the same or different target time periods, or the LP-SS and LP-WUS with the same LP-SS and LP-WUS indexes, meet the same characteristics.

[0171] Alternatively, the UE may also assume that the LP-SS and LP-WUS corresponding to the same candidate LP-SS and LP-WUS indexes or the same LP-SS and LP-WUS indexes within the same specific period meet the same characteristics, and the LP-SS and LP-WUS of different periods do not meet the same characteristics.

[0172] The candidate LP-SS and LP-WUS indexes or the LP-SS and LP-WUS index phases may be determined according to the corresponding occasion index or occasion set index, or according to the index configured in the resource configuration of the LP-SS and LP-WUS, or determined by the index carried by the LP-SS and LP-WUS, for example, by different sequences or load indications.

[0173] For example, the UE may assume that an SSB and an LP-WUS corresponding to the same index satisfy the same characteristics.

[0174] In a fifth embodiment, the terminal determines that the first low power consumption signal and the second low power consumption signal whose indexes satisfy a third predetermined relationship satisfy the same spatial characteristics.

[0175] For example, the UE may consider that the SSB and LP-WUS within one or more target time periods satisfy the same characteristics if SSB index i or candidate SSB index i and LP-WUS occasion set j or LP-WUS occasion index j satisfy a third predetermined relationship.

[0176] 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. For another example, the third predetermined relationship is floor(i / M)=j, or floor(j / M)=i.

[0177] In a sixth embodiment, the terminal determines that the second low power consumption signal, which is a reference signal of the first low power consumption signal, satisfies the same spatial characteristics as the first low power consumption signal.

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

[0179] 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 of the characteristics of the LP-WUS.

[0180] In one or more optional implementations, the method may further include: the terminal merging multiple target low-power signals having the same spatial characteristics. For example, the terminal may merge target low-power signals of the same type having the same spatial characteristics to obtain a measurement result of a beam. Alternatively, the terminal may also merge target low-power signals of different types having the same spatial characteristics, for example, merging the measurement results of LP-SS and LP-WUS having the same spatial characteristics, or merging the measurement results of LP-SS and SSB having the same spatial characteristics based on LP-WUR measurements.

[0181] The technical solutions provided in the embodiments of this application enable network-side devices to transmit LP-SS / LP-WUS using multiple beams, implementing beam sweeping. This provides scheduling flexibility and reduces the impact on other NR signal transmissions. Furthermore, the UE can receive LP-WUS based on LP-SS synchronization information and beam information, improving reception performance and reducing power consumption.
