The method includes: determining a first time-domain resource allocation for a low-power signal, where the first time-domain resource allocation for the low-power signal is associated with a second time-domain resource allocation of a synchronization signal block and a third time-domain resource allocation of a control resource set zero (CORESET 0). By the method of the present application, associating the first time-domain resource allocation of the low-power signal with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0 enables the transmission of the low-power signal based on the time-domain resources of the SSB and the CORESET 0, which can reduce the additional time-domain resource overhead and reduce the loss of system energy-saving gain.

Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication processing method and a communication device. Background Art

[0002] With the development of wireless communication technologies, there are higher requirements for device power consumption. In addition to latency, reliability, and availability, the energy efficiency of user equipment (UE) is also crucial in 5G systems. Currently, 5G devices may need to be charged weekly or daily according to an individual's usage time. Generally, 5G devices consume tens of milliwatts of power when in the radio resource control (RRC) idle or inactive state, and hundreds of milliwatts of power when in the RRC connected state. How to extend the battery life is a necessary condition for improving energy efficiency and user experience.

[0003] To improve the battery life, a low power wake up signal (LP-WUS) mechanism has been introduced in the current field, that is, the user uses a separate low power wake up receiver (LP-WUR) to receive the low power wake up signal, and wakes up the main radio device (MR) through the wake up signal for data transmission and data reception. When the UE does not detect the low power wake up signal, the main receiver is in the deep sleep state, and the power consumption of the terminal is further reduced in this way.

[0004] Therefore, the time domain resource allocation of the low power signal is one of the focuses of 5G communication. Summary of the Invention

[0065] It should be noted that Figure 1 is just a schematic diagram of the architecture of a communication system. Other devices can also be included in the communication system 100, such as wireless relay devices, wireless backhaul devices, core network devices, etc., which are not drawn in Figure 1 The embodiments of this application do not limit the number of various devices included in this communication system.

[0066] The embodiments of the present application can be applied to downlink signal transmission, can also be applied to uplink signal transmission, and can also be applied to sidelink communication (such as signal transmission of device to device (D2D)). For downlink signal transmission, the transmitting device is a network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is a network device. For D2D signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is also a terminal device. The transmission direction of the signal in the embodiments of the present application is not limited.

[0067] The network device 110 and the terminal device 120 can communicate through licensed spectrum, can also communicate through unlicensed spectrum, or can also communicate through both licensed spectrum and unlicensed spectrum at the same time. The network device 110 and the terminal device 120 can communicate through spectrum below 6 gigahertz (GHz), can also communicate through spectrum above 6 GHz, or can also use both spectrum below 6 GHz and spectrum above 6 GHz at the same time. The embodiments of the present application do not limit the spectrum resources used between the network device 110 and the terminal device 120.

[0068] In the embodiments of the present application, the time-domain symbol can be an orthogonal frequency division multiplexing (OFDM) symbol, or can also be a discrete Fourier transform-spread OFDM (DFT-s-OFDM) symbol. If not specifically stated, the symbols in the embodiments of the present application all refer to time-domain symbols.

[0069] It can be understood that in the embodiments of the present application, the physical downlink shared channel (PDSCH), the physical downlink control channel (PDCCH), and the physical uplink shared channel (PUSCH) are only examples of the downlink data channel, the downlink control channel, and the uplink data channel respectively. In different systems and different scenarios, the data channel and the control channel may have different names, and the embodiments of the present application do not limit this.

[0070] In an embodiment of the present application, a low power wake up signal (LP-WUS) is introduced in the communication standard. This LP-WUS is received using a separate receiver, which is called a low power wake up receiver (LP-WUR) 121. The terminal device 120 needs to use the main radio (MR) 122 to normally process downlink and / or uplink data.

[0071] In a possible implementation, when the LP-WUR 121 of the terminal device 120 receives the LP-WUS and the LP-WUS indicates wake-up, the terminal device 120 will turn on the MR 122 to receive and process downlink and / or uplink signals.

[0072] In a possible implementation, if the LP-WUR 121 of the terminal device 120 does not receive the LP-WUS signal, or the LP-WUS received by the LP-WUR 121 of the terminal device 120 indicates not to wake up, the terminal device 120 will keep the MR 122 in a sleep state.

[0073] Optionally, the LP-WUS signal can be used in states such as radio resource control (RRC) connected, inactive, and idle.

[0074] In a possible implementation, the sleep state of the MR 122 can include four types: ultra-deep sleep, deep sleep, light sleep, and microsleep.

[0075] In the communication system 100, the network device 110 is widely deployed to provide various telecommunication services, such as voice, video, data, messaging, and broadcasting. To connect to the network device 110, the terminal device 120 may need to obtain synchronization and acquire the necessary system information. In a wireless communication network such as NR, the synchronization and access processes may involve several signals, for example, the primary synchronization signal (PSS) and the secondary synchronization signal (SSS).

[0076] The PSS can allow network detection in the presence of a high initial frequency error. The SSS can allow more precise frequency adjustment and channel estimation while providing basic network information, such as the cell identifier (ID).

[0077] The physical broadcast channel (PBCH) can provide a subset of the minimum system information for random access and the configuration for obtaining the remaining minimum system information. It can also provide timing information within a cell, for example, to separate the timing between beams transmitted from the cell. The amount of information suitable for the PBCH is limited to control the size. In addition, the demodulation reference signal (DMRS) can be interleaved with the PBCH resources to properly receive the PBCH.

[0078] The SS / PBCH block, which can also be referred to as an SSB, can include the above-mentioned signals (such as PSS, SSS, and DMRS) and the PBCH. For example, depending on the frequency range, the SSB can have a subcarrier space (SCS) of 15 kHz, 30 kHz, 120 kHz, or 240 kHz.

[0079] Figure 2 It is an example diagram of an exemplary SSB mapping provided by an embodiment of the present application. In Figure 2 each numbered small box represents an orthogonal frequency division multiplexing (OFDM) symbol, and the black symbols represent the mapping of the candidate SSB positions where the SSB can be transmitted. As Figure 2 shown, one candidate SSB position can correspond to four OFDM symbols. Figure 2 It shows the exemplary candidate SSB positions in their corresponding two time slots for SCSs of 15 kHz, 30 kHz (including mode 1 and mode 2), and 120 kHz respectively, and in its corresponding four time slots for an SCS of 240 kHz.

[0080] In a possible implementation, the SSB burst set can be transmitted periodically according to the period configured in the system information. For example, it can be assumed that a 20-ms SSB burst set period is used for initial access. By using the SSB in the SSB burst set, the UE can determine the downlink timing and / or frequency offset, etc., and obtain some basic system information from the PBCH. When the UE obtains downlink synchronization, it can know in which time slots SSB transmissions are expected. Therefore, it may be necessary to provide the position of the SSB in the SSB burst set to the UE to derive subframe-level synchronization.

[0081] In addition to synchronization, some system information may also be important for the terminal device 120 to connect to the network device 110. The system information may be carried in the PDSCH scheduled by the PDCCH in the control resource set zero (CORESET 0) configured by the PBCH in NR. The system information may be used to indicate the bitmap of the actually transmitted SSB.

[0082] The CORESET 0 configured by the PBCH may also be used for other system information, paging, and / or random access response, etc. In one possible implementation, the CORESET 0 configured by the PBCH may include multiple resource blocks in the frequency domain and multiple OFDM symbols in the time domain.

[0083] After detecting an SSB, the UE may attempt to search for possible candidate PDCCHs at least partially based on the CORESET 0 configuration (if it exists in the PBCH). In one possible implementation, there may be several possible multiplexing patterns between the CORESET 0 configured by the PBCH and the SSB.

[0084] Figure 3 is a diagram of an exemplary multiplexing pattern for SSB and CORESET 0 provided by an embodiment of the present application. As Figure 3 shown, three multiplexing patterns (shown as Pattern 1, Pattern 2, and Pattern 3) may be applicable to the SSB and CORESET in the time domain and / or frequency domain. Among these multiplexing patterns, Pattern 1 may be supported in the frequency band below 6 GHz and / or above 6 GHz, while Pattern 2 and Pattern 3 are only supported in the frequency band above 6 GHz.

[0085] In a possible implementation, each multiplexing pattern may have a set of supported parameter set combinations {SSB SCS, PDCCH SCS}. For example, in a sub-6 GHz band, a set of parameter set combinations {SSB SCS, PDCCH SCS} supported by pattern 1 may include {15 kHz, 15 kHz}, {15 kHz, 30 kHz}, {30 kHz, 15 kHz}, and {30 kHz, 30 kHz}. In a band above 6 GHz, a set of parameter set combinations {SSB SCS, PDCCH SCS} supported by pattern 1 may include {120 kHz, 60 kHz}, {120 kHz, 120 kHz}, {240 kHz, 60 kHz}, and {240 kHz, 120 kHz}. Similarly, in a band above 6 GHz, a set of parameter set combinations {SSB SCS, PDCCH SCS} supported by pattern 2 may include {120 kHz, 60 kHz} and {240 kHz, 120 kHz}. In a band above 6 GHz, a set of parameter set combinations {SSB SCS, PDCCH SCS} supported by pattern 3 may include {120 kHz, 120 kHz}.

[0086] According to some possible embodiments, the Type0-PDCCH common search space (C-SS) may be a search space for scheduling system information block 1 (SIB1). The configuration of the Type0-PDCCH C-SS is specified in Section 13 of 3GPP TS 38.213. Additionally, in 3GPP TS 38.213, some PDCCH monitoring occasions and related configurations (such as monitoring periods, monitoring windows, etc.) for patterns 1, 2, and 3 are also defined.

[0087] Figure 3 The relationship between the bandwidth of the PDSCH and the bandwidth of the CORESET containing the PDCCH that schedules the PDSCH is also shown.

[0088] In a possible implementation, the initial active downlink (DL) bandwidth part (BWP) may be defined as the frequency position and bandwidth of CORESET 0 and the parameter set of system information. The PDSCH delivering system information may be restricted within the initial active DL BWP. The UE may obtain specific resource configurations (such as time-domain and / or frequency-domain resource allocations) from downlink control information (DCI). The DCI may be used to schedule SIB1, for paging, random access, etc.

[0089] In a possible implementation, for all SSB and CORESET 0 multiplexing patterns, the DCI size can be predefined and constant. For example, the DCI can have the same format as DCI format 1_0. The DCI carried by the PDCCH in the CORESET configured by the PBCH can include indication information about time-domain resource allocation. For example, one or more bits indicating the time-domain resource allocation.

[0090] For different multiplexing patterns between SSB and CORESET 0, the total number of bits indicating time-domain resource allocation can be different. For multiplexing patterns 2 and 3, if it is assumed that the PDSCH is time-aligned with the SSB, then time-domain resource allocation bits may not be necessary. Additionally, for different multiplexing patterns between SSB and CORESET 0, there may be different requirements for the number of time-domain resource allocation bits in the DCI. For example, for the cases of multiplexing patterns 2 and 3, the number of time-domain resource allocation bits in the DCI carried by the PDCCH in CORESET 0 is less than that in the case of multiplexing pattern 1. On the other hand, for multiplexing patterns 2 and 3, in the case where the PDSCH is always scheduled to be time-aligned with the associated SSB, this may pose a direct limitation on the flexibility of time-domain resource allocation. Therefore, it may be necessary to introduce an effective scheme to more efficiently configure and utilize the indication information of time-domain resource allocation.

[0091] In the solutions proposed in some possible embodiments, the network device can provide the terminal device with the indication information of time-domain resource allocation. For example, for various multiplexing patterns between SSB and CORESET 0, indication information such as one or more bits can be included in the time-domain resource allocation field in the DCI carried by the PDCCH in CORESET 0. For a specified multiplexing pattern (e.g., multiplexing pattern 2 and / or pattern 3), some or all of the time-domain resource allocation bits can be reused for other purposes in addition to indicating time-domain resource allocation. Optionally, at least a part of the time-domain resource allocation bits can also be used together with one or more other indicators (e.g., one or more reserved bits / code points, one or more bits / code points in use, etc.) in the DCI carried by the PDCCH in CORESET 0 to indicate other information.

[0092] In a possible implementation, in a wireless communication network such as 5G / NR, a UE-specific radio resource control (RRC) message with a bitmap can be used to indicate the actually transmitted SSBs. To determine the set of actually transmitted SSBs, the UE may need to obtain system information and / or RRC messages containing the bitmap of the actually transmitted SSBs. Additionally, the UE may also need to know the SSB burst set period based on the system information and / or RRC messages.

[0093] In a possible implementation, the indication information of the time domain resource allocation in the DCI carried by the PDCCH in CORESET 0 can be reused to indicate which subsets of the candidate SSB positions have actually transmitted SSBs. This can enable the UE to know which set of SSBs has been actually transmitted before the UE obtains the system information and RRC messages containing the bitmap of the actually transmitted SSBs. Optionally or additionally, at least a part of the indication information of the time domain resource allocation can be used to indicate the SSB burst set period, so that in the case where the UE cannot obtain the SSB burst set period based on the system information and RRC messages within the SSB burst set period, the UE can know the duration of an SSB burst set.

[0094] In a possible implementation, the indication information of the time domain resource allocation in the DCI carried by a channel such as the PDCCH in CORESET 0 can be used to indicate the time domain resource allocation and one or more SSBs that are not transmitted. The time domain resource allocation can be applied to the PDSCH scheduled by the PDCCH in CORESET 0. According to this time domain resource allocation, the scheduled PDSCH can overlap with other CORESETs. Since the CORESETs overlapping with the PDSCH can be associated with different SSBs, the UE can assume that the SSBs associated with the overlapping CORESETs are not transmitted. Therefore, the indication information of the time domain resource allocation in the DCI (such as 4 time domain resource allocation bits) can also be used as an indication for one or more non-transmitted SSBs.

[0095] It should be noted that some embodiments of the present disclosure are described with respect to 5G or NR systems, and 5G or NR systems are used as non-limiting examples of specific exemplary network configurations and system deployments.

[0097] S401. Determine the first time-domain resource allocation of the low-power signal.

[0098] Among them, the first time-domain resource allocation of the low-power signal is associated with the second time-domain resource allocation of the synchronization signal block and the third time-domain resource allocation of the control resource set zero (CORESET 0).

[0099] The synchronization signal block can be a synchronization signal and a physical broadcast channel block (Synchronization Signal and PBCH Block, SSB), or any suitable signal block that can facilitate the synchronization between the terminal device and the network device and the access to the network device. The name is not limited in this application.

[0100] The second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0 have been allocated according to the communication system application scenario and service requirements. That is to say, the second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0 each have corresponding time-domain resources.

[0101] In a possible implementation manner, the network device can determine the first time-domain resource allocation of the low-power signal according to the indication of the high-layer signaling, so that the first time-domain resource allocation of the low-power signal is associated with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0.

[0102] In a possible implementation manner, the network device can determine the first time-domain resource allocation of the low-power signal by itself according to the communication system application scenario and service requirements, so that the first time-domain resource allocation of the low-power signal is associated with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0.

[0103] In a possible implementation manner, the network device can convey indication information associated with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0 to the terminal device. Among them, at least a part of the indication information is allowed to at least partially indicate the first time-domain resource allocation of the low-power signal, and the frequency-domain resource of the low-power signal is different from the frequency-domain resources of the SSB and the CORESET 0.

[0104] Specifically, after determining the first time-domain resource allocation of the low-power signal, the network device can indicate the first time-domain resource allocation of the low-power signal to the terminal device by conveying indication information associated with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of CORESET 0. At least a part of the indication information is allowed to at least partially indicate the first time-domain resource allocation of the low-power signal. For example, at least a part of the existing indication information can be reused or the reserved part of the existing indication information can be utilized to indicate the first time-domain resource allocation of the low-power signal. Moreover, in order not to interfere with the SSB and CORESET 0, the frequency-domain resources other than the frequency-domain resources of the SSB and CORESET 0 in the BWP can be used to carry the low-power signal.

[0105] For example, refer to Figure 5 , Figure 5 which is a diagram showing an example of the time-frequency resource allocation of the low-power signal, the SSB, and CORESET 0 provided by an embodiment of this application. As Figure 5 shown, in the 3 multiplexing modes of the SSB and CORESET 0, the first time-domain resource allocation of the low-power signal can be associated with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of CORESET 0, and the frequency-domain resources of the low-power signal are different from the frequency-domain resources of the SSB and CORESET 0.

[0106] In a possible implementation, the CORESET 0 scheduling indicates a system information block, and the system information block has a fourth time-domain resource allocation. The set of time-domain resources corresponding to the first time-domain resource allocation can be a subset of the set of time-domain resources corresponding to the second time-domain resource allocation, the third time-domain resource allocation, and the fourth time-domain resource allocation.

[0107] Specifically, the DCI in the CORESET 0 can schedule and indicate a system information block, for example, SIB1. Generally, SIB1 is carried by the PDSCH and has a fourth time-domain resource allocation. The set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal can be a subset of the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1.

[0108] In this application, the subset of a set includes the empty set and the set itself.

[0109] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal may be an empty set, which means that no time-domain resources are allocated for the low-power signal. That is, in the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1, the low-power signal is not transmitted.

[0110] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal may be the same as the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1. See Figure 5 , for the three multiplexing modes of the SSB and CORESET 0, the PDSCH in the three multiplexing modes can carry SIB1 indicated by DCI in CORESET 0. The set of time-domain resources allocated for the low-power signal may be the same as the set of time-domain resources of the SSB, the set of time-domain resources of CORESET 0, and the set of time-domain resources of the PDSCH carrying SIB1. In other words, the symbol positions occupied by the low-power signal can be aligned in time resources with the symbol positions occupied by the SSB, the symbol positions occupied by CORESET 0, and the symbol positions of the PDSCH carrying SIB1. That is, the low-power signal is transmitted on all time-domain resources corresponding to the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1.

[0111] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal may be a non-empty proper subset of the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1. That is, on the time-domain resources corresponding to the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1, only some time-domain resources are configured to transmit the low-power signal.

[0112] In a possible implementation, the set of time-domain resources corresponding to the first time-domain resource allocation may be a subset of the set of time-domain resources corresponding to the second time-domain resource allocation and the set of time-domain resources corresponding to the third time-domain resource allocation.

[0113] See Figure 5For modes 2 and 3 among the three multiplexing modes of SSB and CORESET 0, since the PDSCH is always scheduled to be time-aligned with the associated SSB, the set of time-domain resources allocated to the low-power signal can be the same as only the set of time-domain resources of the SSB and the set of time-domain resources of CORESET 0. In other words, the symbol positions occupied by the low-power signal can be time-aligned only with the symbol positions occupied by the SSB and the symbol positions occupied by CORESET 0 in terms of time resources.

[0114] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal can be an empty set, which means that no time-domain resources are allocated to the low-power signal. That is, the low-power signal is not transmitted in the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB and the set of time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0115] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal can be the same as the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB and the set of time-domain resources corresponding to the third time-domain resource allocation of CORESET 0. For example, Figure 5 the cases shown in modes 2 and 3. That is, the low-power signal is transmitted on all the time-domain resources corresponding to the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB and the set of time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0116] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal can be a non-empty proper subset of the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the set of time-domain resources corresponding to the third time-domain resource allocation of CORESET 0, and the set of time-domain resources corresponding to the fourth time-domain resource allocation of SIB1. That is, only some of the time-domain resources in the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB and the set of time-domain resources corresponding to the third time-domain resource allocation of CORESET 0 are configured to transmit the low-power signal.

[0117] In a possible implementation, the low-power signal can include a low-power synchronization signal, and the time-domain resources of the low-power synchronization signal can be at least the same as at least some of the time-domain resources corresponding to the second time-domain resource allocation.

[0118] The low power synchronization signal (LP-SS) is at least used for the LP-WUR of the terminal device to perform coarse time synchronization and / or coarse frequency synchronization with respect to the network device, so as to facilitate the LP-WUR to be able to receive the LP-WUS to wake up the MR. The name of the low power synchronization signal is not limited in this application.

[0119] See Figure 6 , the time domain resources of the LP-SS can be at least the same as at least part of the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0120] Optionally, the time domain resources of the LP-SS can be the same as part of the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0121] For example, in the three multiplexing modes of the SSB and the CORESET 0, the LP-SS can occupy some symbol positions of the SSB, such as Figure 6 shown in (6b) and (6f) in

[0122] Optionally, the time domain resources of the LP-SS can be the same as the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0123] For example, in the three multiplexing modes of the SSB and the CORESET 0, the LP-SS can occupy the symbol positions of the SSB, such as Figure 6 shown in (6a), (6c), and (6d) in

[0124] Optionally, the time domain resources of the LP-SS can be at least the same as the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0125] For example, for example, in mode 2 of the three multiplexing modes of the SSB and the CORESET 0, the LP-SS can occupy the symbol positions of the SSB and the symbol positions of the CORESET 0, such as Figure 6 shown in (6e) in

[0126] In other words, in mode 1 and mode 3 of the three multiplexing modes of the SSB and the CORESET 0, the LP-SS can occupy at least part of the positions of the symbols of the SSB; in mode 2, the LP-SS can occupy at least part of the positions of the symbols of the SSB and at least part of the positions of the symbols of the CORESET 0.

[0127] For example, the second time-domain resource allocation of the SSB may correspond to a time-domain resource of 4 symbols, and the third time-domain resource allocation of CORESET 0 may correspond to a time-domain resource of 2 symbols. In Mode 1 and Mode 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS may occupy the time-domain resources corresponding to any combination of 1 to 4 symbols among the 4 symbols of the SSB; while in Mode 2 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS may occupy the time-domain resources corresponding to any combination of 1 to 6 symbols among a total of 6 symbols, namely the 4 symbols of the SSB and the 2 symbols of CORESET 0 (this application does not limit whether the symbols are continuous).

[0128] Furthermore, for the three multiplexing modes, the LP-SS may correspond one-to-one with the beam. That is, when certain SSBs are determined not to be transmitted, the LP-SS is not transmitted on the corresponding time-domain resources either.

[0129] For Mode 1 of the multiplexing mode, the LP-SS may also be repeatedly detected at the position of SIB1. Moreover, the number of repeated checks and / or the detection conditions may be configured, and the configuration information may be preset or indicated by the master information block (MIB).

[0130] In a possible implementation manner, the low-power signal may include the LP-SS, and the time-domain resources of the LP-SS may be at least the same as at least part of the time-domain resources corresponding to the third time-domain resource allocation.

[0131] See Figure 7 , the time-domain resources of the LP-SS may be at least the same as at least part of the time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0132] Optionally, the time-domain resources of the LP-SS may be the same as part of the time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0133] For example, in Mode 2 and Mode 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS may occupy some symbol positions of CORESET 0, such as Figure 7 in (7c) (this case in Mode 2 is not shown).

[0134] Optionally, the time-domain resources of the LP-SS may be the same as the time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0135] For example, in Mode 2 and Mode 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS may occupy the symbol positions of CORESET 0, such asFigure 7 as shown in (7a) therein (this case in mode 3 is not shown).

[0136] Optionally, the time-domain resources of the LP-SS can be at least the same as the time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0137] For example, in modes 2 and 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS can occupy the symbol positions of the SSB and the symbol positions of CORESET 0, as Figure 7 shown in (7b) therein (this case in mode 3 is not shown).

[0138] In other words, in modes 2 and 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS can occupy at least part of the positions of the symbols of CORESET 0 and at least part of the positions of the symbols of the SSB.

[0139] For example, the second time-domain resource allocation of the SSB can correspond to the time-domain resources of 4 symbols, and the third time-domain resource allocation of CORESET 0 can correspond to the time-domain resources of 2 symbols. In mode 2 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS can occupy any combination of 1 to 6 symbols out of a total of 6 symbols including 4 symbols of the SSB and 2 symbols of CORESET 0; while in mode 3 of the three multiplexing modes of the SSB and CORESET 0, since the symbols of CORESET 0 and the SSB are aligned in the time domain, the LP-SS can occupy any combination of 1 to 4 symbols out of the 4 symbols of the SSB (this application does not limit whether the symbols are continuous).

[0140] In a possible implementation, the low-power signal further includes LP-WUS. The frequency-domain resources of the LP-WUS can be the same as those of the LP-SS, and the time-domain resources of the LP-WUS are at least part of the time-domain resources in the set of the time-domain resources corresponding to the first time-domain resource allocation of the low-power signal except for the time-domain resources of the LP-SS.

[0141] The LP-WUS can be, for example, Figure 6 and Figure 7 other low-power signals as shown in, when the frequency-domain resources of the LP-WUS are the same as those of the LP-SS, such as Figure 6 in (6a), (6b), (6d), (6f) and Figure 7As shown in (7a) and (7c), LP-WUS and LP-SS can be configured in a time division multiplexing (TDM) manner. Moreover, LP-WUS can occupy some or all of the time domain resources in the set of time domain resources corresponding to the first time domain resource allocation of the low-power signal, excluding the time domain resources of LP-SS (this application does not limit whether the symbols are continuous).

[0142] In a possible implementation, the low-power signal further includes LP-WUS. The frequency domain resources of LP-WUS and LP-SS can be different, and the time domain resources of LP-WUS are at least part of the set of time domain resources corresponding to the first time domain resource allocation of the low-power signal, excluding the time domain resources of LP-SS.

[0143] When the frequency domain resources of LP-WUS and LP-SS are different (i.e., LP-WUS and LP-SS are configured in a frequency division multiplexing (FDM) manner), LP-WUS can occupy some or all of the time domain resources in the set of time domain resources corresponding to the first time domain resource allocation of the low-power signal (this application does not limit whether the symbols are continuous).

[0144] Optionally, the time domain resources of LP-WUS are at least part of the set of time domain resources corresponding to the first time domain resource allocation of the low-power signal, excluding the time domain resources of LP-SS. That is, during the transmission of LP-SS, LP-WUS is not transmitted.

[0145] For Mode 1 among the three multiplexing modes, the time domain resource configuration of LP-WUS also needs to meet the configuration of Type0-PDCCH C-SS for Mode 1 in 3GPP TS38.213, so as to achieve the transmission of LP-WUS at appropriate PDCCH monitoring opportunities and related configurations (such as monitoring period, monitoring window, etc.).

[0146] In a possible implementation, the low-power signal can include LP-WUS, and the time domain resources of LP-WUS can be the same as at least part of the time domain resources corresponding to the first time domain resource allocation.

[0147] See Figure 8 , Figure 8 which is an example diagram of the time domain resource allocation of a low-power wake-up signal (LP-WUS) provided by an embodiment of this application.

[0148] In the three multiplexing modes of SSB and CORESET 0, the time-domain resources of LP-WUS can all be the same as at least part of the time-domain resources corresponding to the first time-domain resource allocation. In other words, the time-domain resources of LP-WUS can be a non-empty subset of the set of time-domain resources corresponding to the first time-domain resource allocation. For example, Figure 8 (8a) to (8f) in Figure 8 . Moreover, the time-domain resources of LP-WUS can be discontinuous. For example,

[0149] (8b) and (8e) in

[0150] It is easy to understand that the set of time-domain resources of LP-WUS can be the same as the set of time-domain resources corresponding to the first time-domain resource allocation. That is to say, in this case, all the time-domain resources corresponding to the first time-domain resource allocation can be used for the transmission of LP-WUS.

[0151] In the three multiplexing modes of SSB and CORESET 0, the time-domain resources of LP-WUS can all be the same as at least part of the time-domain resources corresponding to the second time-domain resource allocation. In other words, the time-domain resources of LP-WUS can be a non-empty subset of the set of time-domain resources corresponding to the second time-domain resource allocation. For example, Figure 8 (8a), (8c), (8d), and (8f) in Figure 8 . Moreover, the time-domain resources of LP-WUS can be discontinuous. For example,

[0152] It is easy to understand that when the time-domain resources of LP-WUS are a non-empty subset of the set of time-domain resources corresponding to the second time-domain resource allocation, LP-WUS can correspond to SSB.

[0153] In a possible implementation, LP-WUS can be associated with a user equipment group (UE group), where the index of the user equipment group is associated with the index of the SSB corresponding to the time-domain resources of LP-WUS.

[0154] Specifically, the user equipment group can be multiple UEs grouped according to specific criteria.

[0155] Optionally, considering the different positions of UEs, UEs with the same beam or related beams can be in one group, that is, the user equipment group can be divided according to the beam.

[0156] Optionally, the UE group can be divided according to the slot structure type, and different numerologies or services can be put into different groups.

[0157] Optionally, for UEs with different processing capabilities, they can be grouped according to the supported bandwidth range.

[0158] This application does not limit the grouping method of user equipment groups.

[0159] LP-WUS can be a paging message for a user equipment group. In the SSB burst set period (e.g., 20 ms), since LP-WUS can correspond to the SSB, LP-WUS can be configured for a specific user equipment group according to the index of the SSB. In other words, the index of the SSB can correspond to the index of the user equipment group, and LP-WUS can be configured as a paging message for the user equipment group with the index corresponding to the user equipment group based on the index of the SSB corresponding to the time domain resource of LP-WUS.

[0160] In one possible implementation, one SSB can correspond to one user equipment group.

[0161] Optionally, based on a hash function, the index of the SSB can be corresponded to the index of the user equipment group, and according to the SSB burst set period (i.e., the beam scanning period), the corresponding relationship between the index of the SSB and the index of the user equipment group can be updated so that the user equipment group can traverse all beams.

[0162] Optionally, when the corresponding relationship between the index of the SSB and the index of the user equipment group has been determined in the current beam scanning period, the corresponding relationship between the index of the SSB and the index of the user equipment group in the next beam scanning period can be updated to Index _SSB =(Index _UE group +a)mod N _UE group , where Index _SSB is the index of the SSB, Index _UE group is the index of the user equipment group in the current beam scanning period, N _UE group is the number of groups of user equipment, and a can be any positive integer less than N _UE group and relatively prime to N _UE group so that the user equipment group can traverse all beams.

[0163] In one possible implementation, multiple SSBs can correspond to one user equipment group.

[0164] Optionally, multiple SSBs in an SSB burst set period can correspond to a user equipment group, so that LP-WUS can be repeatedly sent to a specific user equipment group at multiple SSB time domain positions, or a longer time domain symbol can be used to send LP-WUS.

[0165] In a possible implementation, the SSB burst set can be associated with a user equipment group. That is, all SSBs in the SSB burst set period are corresponding to a specific user equipment group, so that in an SSB burst set period (for example, 20 ms), a specific user group can scan all beams.

[0166] Optionally, the starting position of the SSB burst set period can be at the start of a period of Connected Mode Discontinuous Reception (CDRX) or Extended / Enhanced DRX (EDRX) in the connected mode.

[0167] In a possible implementation, the first time domain resource allocation of the low-power signal is also associated with the time domain resource allocation of a Tracking Reference Signal (TRS). The method further includes: sending the TRS to a terminal device, so that the terminal device determines the first time domain resource allocation of the low-power signal based on the time domain resource allocation of the TRS.

[0168] Optionally, the symbol position of LP-SS or the symbol position of LP-WUS can be determined based on the symbol position of the TRS. For example, the symbol position of LP-SS or the symbol position of LP-WUS can be the same as the symbol position of the TRS, or be offset by a predefined offset value.

[0169] In Figure 4 In the described method, the first time domain resource allocation of the low-power signal determined by the network device is associated with the second time domain resource allocation of the SSB and the third time domain resource allocation of CORESET 0. The low-power signal can be transmitted based on the time domain resources of the SSB and CORESET 0, which can reduce the additional time domain resource overhead and reduce the loss of system energy saving gain.

[0171] S901. Determine the first time-domain resource allocation for the low-power signal.

[0172] Among them, the first time-domain resource allocation for the low-power signal is associated with the second time-domain resource allocation of the synchronization signal block and the third time-domain resource allocation of the control resource set zero (CORESET 0).

[0173] The synchronization signal block may be a synchronization signal and a physical broadcast channel block (Synchronization Signal and PBCH Block, SSB), or any suitable signal block that can facilitate the synchronization of the terminal device with the network device and access to the network device. The present application does not limit the name.

[0174] The second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0 have been allocated according to the communication system application scenario and service requirements. That is, the second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0 each have corresponding time-domain resources.

[0175] In a possible implementation, the terminal device may determine the first time-domain resource allocation for the low-power signal according to the indication of the high-layer signaling, so that the first time-domain resource allocation for the low-power signal is associated with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0.

[0176] In a possible implementation, the terminal device may determine the first time-domain resource allocation for the low-power signal by itself according to the predefined configuration, so that the first time-domain resource allocation for the low-power signal is associated with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0.

[0177] In a possible implementation, the terminal device may receive indication information associated with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of the CORESET 0 from the network device to determine the first time-domain resource allocation for the low-power signal. Among them, at least a part of the indication information is allowed to at least partially indicate the first time-domain resource allocation for the low-power signal, and the frequency-domain resource of the low-power signal is different from the frequency-domain resources of the SSB and the CORESET 0.

[0178] Specifically, after determining the first time-domain resource allocation of the low-power signal, the network device can indicate the first time-domain resource allocation of the low-power signal to the terminal device by conveying indication information associated with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of CORESET 0 to the terminal device. The terminal device can determine the first time-domain resource allocation of the low-power signal based on this indication information. At least a part of the indication information is allowed to at least partially indicate the first time-domain resource allocation of the low-power signal. For example, at least a part of the existing indication information can be reused or the reserved part of the existing indication information can be utilized to indicate the first time-domain resource allocation of the low-power signal. Also, in order not to interfere with the SSB and CORESET 0, the frequency-domain resources in the BWP other than the frequency-domain resources of the SSB and CORESET 0 can be used to carry the low-power signal.

[0179] For example, refer to Figure 5 , Figure 5 FIG. shows an example of the time-frequency resource allocation of the low-power signal, the SSB, and CORESET 0 provided by an embodiment of the present application. As Figure 5 shown, in the 3 multiplexing modes of the SSB and CORESET 0, the first time-domain resource allocation of the low-power signal can be associated with the second time-domain resource allocation of the SSB and the third time-domain resource allocation of CORESET 0, and the frequency-domain resources of the low-power signal are different from the frequency-domain resources of the SSB and CORESET 0.

[0180] In a possible implementation, the CORESET 0 scheduling indicates a system information block, and the system information block has a fourth time-domain resource allocation. The set of time-domain resources corresponding to the first time-domain resource allocation can be a subset of the set of time-domain resources corresponding to the second time-domain resource allocation, the third time-domain resource allocation, and the fourth time-domain resource allocation.

[0181] Specifically, the DCI in CORESET 0 can schedule and indicate a system information block, for example, SIB1. Generally, SIB1 is carried by the PDSCH and has a fourth time-domain resource allocation. The set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal can be a subset of the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1.

[0182] In the present application, the subset of a set includes an empty set and the set itself.

[0183] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal may be an empty set, which means that no time-domain resources are allocated for the low-power signal. That is to say, the low-power signal is not transmitted in the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1.

[0184] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal may be the same as the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1. Refer to Figure 5 , for the three multiplexing modes of the SSB and CORESET 0, the PDSCH in the three multiplexing modes can carry SIB1 indicated by DCI in CORESET 0. The set of time-domain resources allocated to the low-power signal may be the same as the set of time-domain resources of the SSB, the set of time-domain resources of CORESET 0, and the set of time-domain resources of the PDSCH carrying SIB1. In other words, the symbol positions occupied by the low-power signal can be aligned in time resources with the symbol positions occupied by the SSB, the symbol positions occupied by CORESET 0, and the symbol positions of the PDSCH carrying SIB1. That is to say, the low-power signal is transmitted on all time-domain resources corresponding to the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1.

[0185] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal may be a non-empty proper subset of the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1. That is to say, only some of the time-domain resources are configured to transmit the low-power signal on the time-domain resources corresponding to the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the third time-domain resource allocation of CORESET 0, and the fourth time-domain resource allocation of SIB1.

[0186] In a possible implementation, the set of time-domain resources corresponding to the first time-domain resource allocation may be a subset of the set of time-domain resources corresponding to the second time-domain resource allocation and the set of time-domain resources corresponding to the third time-domain resource allocation.

[0187] Refer to Figure 5, for Mode 2 and Mode 3 among the three multiplexing modes of SSB and CORESET 0, since the PDSCH is always scheduled to be time-aligned with the associated SSB, the set of time-domain resources allocated to the low-power signal can be the same as only the set of time-domain resources of the SSB and the set of time-domain resources of CORESET 0. In other words, the symbol positions occupied by the low-power signal can be time-aligned only with the symbol positions occupied by the SSB and the symbol positions occupied by CORESET 0 in terms of time resources.

[0188] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal can be an empty set, which means that no time-domain resources are allocated to the low-power signal. That is, the low-power signal is not transmitted in the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB and the set of time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0189] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal can be the same as the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB and the set of time-domain resources corresponding to the third time-domain resource allocation of CORESET 0. For example, Figure 5 the cases shown in Mode 2 and Mode 3. That is, the low-power signal is transmitted on all the time-domain resources corresponding to the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB and the set of time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0190] Optionally, the set of time-domain resources corresponding to the first time-domain resource allocation of the low-power signal can be a non-empty proper subset of the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB, the set of time-domain resources corresponding to the third time-domain resource allocation of CORESET 0, and the set of time-domain resources corresponding to the fourth time-domain resource allocation of SIB1. That is, only some of the time-domain resources are configured to transmit the low-power signal in the time-domain resources corresponding to the set of time-domain resources corresponding to the second time-domain resource allocation of the SSB and the set of time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0191] In a possible implementation, the low-power signal can include a low-power synchronization signal, and the time-domain resources of the low-power synchronization signal can be at least the same as at least some of the time-domain resources corresponding to the second time-domain resource allocation.

[0192] The low power synchronization signal (LP-SS) is at least used for the LP-WUR of the terminal device to perform coarse time synchronization and / or coarse frequency synchronization with respect to the network device, so as to facilitate the LP-WUR to receive the LP-WUS to wake up the MR. The name of the low power synchronization signal is not limited in this application.

[0193] See Figure 6 , the time domain resources of the LP-SS can be at least the same as at least part of the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0194] Optionally, the time domain resources of the LP-SS can be the same as part of the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0195] For example, in the three multiplexing modes of the SSB and CORESET 0, the LP-SS can occupy some symbol positions of the SSB, such as Figure 6 shown in (6b) and (6f) in

[0196] Optionally, the time domain resources of the LP-SS can be the same as the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0197] For example, in the three multiplexing modes of the SSB and CORESET 0, the LP-SS can occupy the symbol positions of the SSB, such as Figure 6 shown in (6a), (6c), and (6d) in

[0198] Optionally, the time domain resources of the LP-SS can be at least the same as the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0199] For example, in mode 2 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS can occupy the symbol positions of the SSB and the symbol positions of CORESET 0, such as Figure 6 shown in (6e) in

[0200] In other words, in mode 1 and mode 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS can occupy at least part of the positions of the symbols of the SSB; in mode 2, the LP-SS can occupy at least part of the positions of the symbols of the SSB and at least part of the positions of the symbols of CORESET 0.

[0201] For example, the second time-domain resource allocation of the SSB may correspond to a time-domain resource of 4 symbols, and the third time-domain resource allocation of CORESET 0 may correspond to a time-domain resource of 2 symbols. In mode 1 and mode 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS may occupy the time-domain resources corresponding to any combination of 1 to 4 symbols out of the 4 symbols of the SSB; while in mode 2 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS may occupy the time-domain resources corresponding to any combination of 1 to 6 symbols out of a total of 6 symbols including the 4 symbols of the SSB and the 2 symbols of CORESET 0 (this application does not limit whether the symbols are continuous).

[0202] Furthermore, for the three multiplexing modes, the LP-SS may correspond one-to-one with the beam. That is, when some SSBs are determined not to be transmitted, the LP-SS is not transmitted on the corresponding time-domain resources either.

[0203] For multiplexing mode 1, the LP-SS may also be repeatedly detected at the position of SIB1. Moreover, the number of repeated checks and / or the detection conditions may be configured, and the configuration information may be preset or indicated by the master information block (MIB).

[0204] In a possible implementation, the low-power signal may include the LP-SS, and the time-domain resources of the LP-SS may be at least the same as at least part of the time-domain resources corresponding to the third time-domain resource allocation.

[0205] See Figure 7 , the time-domain resources of the LP-SS may be at least the same as at least part of the time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0206] Optionally, the time-domain resources of the LP-SS may be the same as part of the time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0207] For example, in mode 2 and mode 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS may occupy some symbol positions of CORESET 0, such as Figure 7 in (7c) (this case in mode 2 is not shown).

[0208] Optionally, the time-domain resources of the LP-SS may be the same as the time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0209] For example, in mode 2 and mode 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS may occupy the symbol positions of CORESET 0, such asFigure 7 as shown in (7a) therein (this case in Mode 3 is not shown).

[0210] Optionally, the time-domain resources of the LP-SS can be at least the same as the time-domain resources corresponding to the third time-domain resource allocation of CORESET 0.

[0211] For example, in Modes 2 and 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS can occupy the symbol positions of the SSB and the symbol positions of CORESET 0, as Figure 7 shown in (7b) therein (this case in Mode 3 is not shown).

[0212] In other words, in Modes 2 and 3 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS can occupy at least part of the positions of the symbols of CORESET 0 and at least part of the positions of the symbols of the SSB.

[0213] For example, the second time-domain resource allocation of the SSB can correspond to the time-domain resources of 4 symbols, and the third time-domain resource allocation of CORESET 0 can correspond to the time-domain resources of 2 symbols. In Mode 2 of the three multiplexing modes of the SSB and CORESET 0, the LP-SS can occupy any combination of 1 to 6 symbols out of a total of 6 symbols including 4 symbols of the SSB and 2 symbols of CORESET 0; while in Mode 3 of the three multiplexing modes of the SSB and CORESET 0, since the symbols of CORESET 0 and the SSB are aligned in the time domain, the LP-SS can occupy any combination of 1 to 4 symbols out of 4 symbols of the SSB (this application does not limit whether the symbols are continuous).

[0214] In a possible implementation, the low-power signal further includes LP-WUS. The frequency-domain resources of the LP-WUS can be the same as those of the LP-SS, and the time-domain resources of the LP-WUS are at least part of the time-domain resources in the set of the time-domain resources corresponding to the first time-domain resource allocation of the low-power signal except for the time-domain resources of the LP-SS.

[0215] The LP-WUS can be such as Figure 6 and Figure 7 other low-power signals shown in. When the frequency-domain resources of the LP-WUS are the same as those of the LP-SS, such as Figure 6 in (6a), (6b), (6d), (6f) therein, and Figure 7As shown in (7a) and (7c), LP-WUS and LP-SS can be configured in a time division multiplexing (TDM) manner. Moreover, LP-WUS can occupy some or all of the time domain resources in the set of time domain resources corresponding to the first time domain resource allocation of the low-power signal, excluding the time domain resources of LP-SS (this application does not limit whether the symbols are continuous).

[0216] In a possible implementation, the low-power signal further includes LP-WUS. The frequency domain resources of LP-WUS can be different from those of LP-SS. The time domain resources of LP-WUS are at least some of the time domain resources in the set of time domain resources corresponding to the first time domain resource allocation of the low-power signal, excluding the time domain resources of LP-SS.

[0217] When the frequency domain resources of LP-WUS are different from those of LP-SS (i.e., LP-WUS and LP-SS are configured in a frequency division multiplexing (FDM) manner), LP-WUS can occupy some or all of the time domain resources in the set of time domain resources corresponding to the first time domain resource allocation of the low-power signal (this application does not limit whether the symbols are continuous).

[0218] Optionally, the time domain resources of LP-WUS are at least some of the time domain resources in the set of time domain resources corresponding to the first time domain resource allocation of the low-power signal, excluding the time domain resources of LP-SS. That is, during the transmission of LP-SS, LP-WUS is not transmitted.

[0219] For Mode 1 among the three multiplexing modes, the time domain resource configuration of LP-WUS also needs to meet the configuration of Type0-PDCCH C-SS for Mode 1 in 3GPP TS38.213, so as to achieve the transmission of LP-WUS at appropriate PDCCH monitoring opportunities and related configurations (such as monitoring period, monitoring window, etc.).

[0220] In a possible implementation, the low-power signal can include LP-WUS, and the time domain resources of LP-WUS can be the same as at least some of the time domain resources corresponding to the first time domain resource allocation.

[0221] See Figure 8 , Figure 8 which is an example diagram of the time domain resource allocation of a low-power wake-up signal (LP-WUS) provided by an embodiment of this application.

[0222] In the three multiplexing modes of SSB and CORESET 0, the time-domain resources of LP-WUS can be the same as at least part of the time-domain resources corresponding to the first time-domain resource allocation. In other words, the time-domain resources of LP-WUS can be a non-empty subset of the set of time-domain resources corresponding to the first time-domain resource allocation. For example, Figure 8 (8a) to (8f) in Figure 8 . Also, the time-domain resources of LP-WUS can be discontinuous. For example,

[0223] It is easy to understand that the set of time-domain resources of LP-WUS can be the same as the set of time-domain resources corresponding to the first time-domain resource allocation. That is to say, in this case, all the time-domain resources corresponding to the first time-domain resource allocation can be used for the transmission of LP-WUS.

[0224] In a possible implementation, the time-domain resources of LP-WUS are at least the same as at least part of the time-domain resources corresponding to the second time-domain resource allocation.

[0225] In the three multiplexing modes of SSB and CORESET 0, the time-domain resources of LP-WUS can be the same as at least part of the time-domain resources corresponding to the second time-domain resource allocation. In other words, the time-domain resources of LP-WUS can be a non-empty subset of the set of time-domain resources corresponding to the second time-domain resource allocation. For example, Figure 8 (8a), (8c), (8d), (8f) in Figure 8 . Also, the time-domain resources of LP-WUS can be discontinuous. For example,

[0226] It is easy to understand that when the time-domain resources of LP-WUS are a non-empty subset of the set of time-domain resources corresponding to the second time-domain resource allocation, LP-WUS can correspond to SSB.

[0227] In a possible implementation, LP-WUS can be associated with a user equipment group (UE group), where the index of the user equipment group is associated with the index of the SSB corresponding to the time-domain resources of LP-WUS.

[0228] Specifically, the user equipment group can be multiple UEs grouped according to specific criteria.

[0229] Optionally, considering the different positions of UEs, UEs with the same beam or related beams can be in one group, that is, the user equipment group can be divided according to the beam.

[0230] Optionally, the UE group can be divided according to the slot structure type, and different numerologies or services can be put into different groups.

[0231] Optionally, for UEs with different processing capabilities, they can be grouped according to the supported bandwidth range.

[0232] This application does not limit the grouping method of user equipment groups.

[0233] LP-WUS can be a paging message for a user equipment group. In the SSB burst set period (e.g., 20 ms), since LP-WUS can correspond to the SSB, therefore, according to the index of the SSB, for a specific user equipment group, LP-WUS can be configured. In other words, the index of the SSB can correspond to the index of the user equipment group, and based on the index of the SSB corresponding to the time domain resource of LP-WUS, LP-WUS can be configured as a paging message for the user equipment group with the corresponding index of the user equipment group.

[0234] In one possible implementation, one SSB can correspond to one user equipment group.

[0235] Optionally, based on a hash function, the index of the SSB can be corresponded with the index of the user equipment group, and according to the SSB burst set period (i.e., the beam scanning period), the corresponding relationship between the index of the SSB and the index of the user equipment group can be updated, so that the user equipment group can traverse all beams.

[0236] Optionally, when the corresponding relationship between the index of the SSB and the index of the user equipment group has been determined in the current beam scanning period, the corresponding relationship between the index of the SSB and the index of the user equipment group in the next beam scanning period can be updated to Index _SSB =(Index _UE group +a)mod N _UE group , where Index _SSB is the index of the SSB, Index _UE group is the index of the user equipment group in the current beam scanning period, N _UE group is the number of groups of user equipment, and a can be any positive integer less than N _UE group and relatively prime to N _UE group , so that the user equipment group can traverse all beams.

[0237] In one possible implementation, multiple SSBs can correspond to one user equipment group.

[0238] Optionally, multiple SSBs in the SSB burst set period can correspond to a user equipment group, so that LP-WUS can be repeatedly sent to a specific user equipment group at multiple SSB time domain positions, or LP-WUS can be sent using a longer time domain symbol.

[0239] In a possible implementation, the SSB burst set can be associated with a user equipment group. That is, all SSBs in the SSB burst set period are corresponding to a specific user equipment group, so that in one SSB burst set period (for example, 20 ms), a specific user group can scan all the beams.

[0240] Optionally, the start position of the SSB burst set period can be at the start of the period of Connected Mode Discontinuous Reception (CDRX) or Extended / Enhanced DRX (EDRX) in the connected mode.

[0241] In a possible implementation, the first time domain resource allocation of the low-power signal is also associated with the time domain resource allocation of the Tracking Reference Signal (TRS). The method further includes: determining that the TRS is received from the network device; based on the time domain resource allocation of the TRS, determining the first time domain resource allocation of the low-power signal.

[0242] Optionally, the symbol position of LP-SS or the symbol position of LP-WUS can be determined based on the symbol position of the TRS. For example, the symbol position of LP-SS or the symbol position of LP-WUS can be the same as the symbol position of the TRS, or be separated by a predefined offset value.

[0243] In Figure 9 In the described method, the first time domain resource allocation of the low-power signal determined by the terminal device is associated with the second time domain resource allocation of the SSB and the third time domain resource allocation of CORESET 0. The low-power signal can be transmitted based on the time domain resources of the SSB and CORESET 0, which can reduce the additional time domain resource overhead and reduce the loss of the system energy saving gain.

Correspondingly, the terminal device receives the indication information about the first time-domain resource allocation of the low-power signal from the network device.
