By means of the method in the present application, the first time-domain resource allocation for the low-power signal is associated with the second time-domain resource allocation for the SSB and the third time-domain resource allocation for CORESET 0, such that the low-power signal can be transmitted on the basis of time-domain resources for the SSB and CORESET 0, and thus extra time-domain resource overheads can be reduced, thereby reducing systemic energy-saving gain loss.

Description

Communication processing method and communication device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 8, 2024, with application number 202410178171.7 and application name “A Communication Processing Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication processing method and a communication device. Background Art

[0003] With the development of wireless communication technology, higher requirements are being placed on device power consumption. In addition to latency, reliability, and availability, the energy efficiency of user equipment (UE) is also crucial for 5G systems. Currently, 5G devices may need to be charged weekly or daily depending on individual usage time. Typically, 5G devices tend to consume tens of milliwatts of power in the radio resource control (RRC) idle or inactive state and hundreds of milliwatts of power in the RRC connected state. How to extend battery life is a necessary condition for improving energy efficiency and improving user experience.

[0004] To improve battery life, the field has introduced an ultra-low power wake-up signal (LP-WUS) mechanism. That is, the user uses a separate low power wake-up receiver (LP-WUR) to receive a low power wake-up signal, which is used to wake up the main radio (MR) for data transmission and reception. When the UE does not detect the low power wake-up signal, the main receiver is in a deep sleep state, which further reduces the power consumption of the terminal.

[0005] Therefore, time domain resource allocation for low-power signals is one of the key focuses of 5G communications. Summary of the Invention

[0066] It should be noted that Figure 1 is only a schematic diagram of the architecture of a communication system. The communication system 100 may also include other devices, such as wireless relay devices, wireless backhaul devices, core network devices, etc., which are not shown in Figure 1. The embodiments of the present application do not limit the number of various devices included in the communication system.

[0067] The embodiments of the present application can be applied to downlink signal transmission, uplink signal transmission, and sidelink communication (such as device-to-device (D2D) signal transmission). For downlink signal transmission, the sending device is a network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the sending device is a terminal device, and the corresponding receiving device is a network device. For D2D signal transmission, the sending 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.

[0068] The network device 110 and the terminal device 120 can communicate through a licensed spectrum, or through an unlicensed spectrum, or through both a licensed spectrum and an unlicensed spectrum. The network device 110 and the terminal device 120 can communicate through a spectrum below 6 gigahertz (GHz), or through a spectrum above 6 GHz, or through both a spectrum below 6 GHz and a spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used between the network device 110 and the terminal device 120.

[0069] In the embodiments of the present application, the time domain symbols may be orthogonal frequency division multiplexing (OFDM) symbols or discrete Fourier transform spread OFDM (DFT-s-OFDM) symbols. Unless otherwise specified, the symbols in the embodiments of the present application refer to time domain symbols.

[0070] It can be understood that in the embodiments of the present application, the physical downlink share channel (PDSCH), the physical downlink control channel (PDCCH) and the physical uplink share channel (PUSCH) are merely examples of downlink data channels, downlink control channels and uplink data channels, respectively. In different systems and different scenarios, data channels and control channels may have different names, and the embodiments of the present application do not limit this.

[0071] In an embodiment of the present application, a low power wake-up signal (LP-WUS) is introduced into the communication standard. The LP-WUS is received using a separate receiver, referred to as a low power wake-up radio receiver (LP-WUR) 121. The terminal device 120 needs to use a main radio (MR) 122 to properly process downlink and / or uplink data.

[0072] 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 turns on the MR 122 to receive and process downlink and / or uplink signals.

[0073] In one 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 the sleep state.

[0074] Optionally, the LP-WUS signal may be used in radio resource control (RRC) connected, inactive, idle, and other states.

[0075] In a possible implementation, the sleep states of the MR 122 may include four types: ultra-deepsleep, deep sleep, light sleep, and micro sleep.

[0076] In communication system 100, network devices 110 are widely deployed to provide various telecommunication services, such as voice, video, data, messaging, and broadcast. To connect to network device 110, terminal device 120 may need to acquire synchronization and obtain necessary system information. In wireless communication networks such as NR, synchronization and access procedures may involve several signals, such as the primary synchronization signal (PSS) and the secondary synchronization signal (SSS).

[0077] PSS can allow network detection in the presence of high initial frequency errors. SSS can allow more accurate frequency adjustment and channel estimation while providing basic network information such as cell identifiers (IDs).

[0078] 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 the 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 enable proper reception of the PBCH.

[0079] An SS / PBCH block, also referred to as an SSB, may include the aforementioned signals (e.g., PSS, SSS, and DMRS) and PBCH. For example, depending on the frequency range, an SSB may have a subcarrier spacing (SCS) of 15 kHz, 30 kHz, 120 kHz, or 240 kHz.

[0080] Figure 2 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 candidate SSB positions where SSBs can be transmitted. As shown in Figure 2, one candidate SSB position can correspond to four OFDM symbols. Figure 2 shows exemplary candidate SSB positions for 15kHz SCS, 30kHz SCS (including mode 1 and mode 2) and 120kHz SCS in their corresponding two time slots, respectively, and for 240kHz SCS in its corresponding four time slots.

[0081] In one possible implementation, an SSB burst set may be transmitted periodically according to a period configured in the system information. For example, a 20ms SSB burst set period may be assumed for initial access. By using the SSBs in the SSB burst set, the UE can determine downlink timing and / or frequency offset, etc., and obtain some basic system information from the PBCH. When the UE acquires downlink synchronization, it can know in which time slots SSB transmissions are expected. Therefore, the position of the SSB in the SSB burst set may need to be provided to the UE in order to derive subframe-level synchronization.

[0082] 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 0 (CORESET 0) configured by the PBCH in the NR. The system information may be used to indicate a bitmap of the SSBs actually transmitted.

[0083] CORESET 0 configured by PBCH may also be used for other system information, paging and / or random access response, etc. In one possible implementation, CORESET 0 configured by PBCH may include multiple resource blocks in the frequency domain and multiple OFDM symbols in the time domain.

[0084] After detecting an SSB, the UE may attempt to search for possible candidate PDCCHs based at least in part on the CORESET 0 configuration (if present in the PBCH). In one possible implementation, there may be several possible multiplexing patterns between CORESET 0 and the SSB configured by the PBCH.

[0085] FIG3 is a diagram illustrating exemplary multiplexing modes for SSB and CORESET 0 provided in an embodiment of the present application. As shown in FIG3 , three multiplexing modes (shown as Mode 1, Mode 2, and Mode 3) can be applied to SSB and CORESET in the time domain and / or frequency domain. Among these multiplexing modes, Mode 1 can be supported in frequency bands below 6 GHz and / or above 6 GHz, while Mode 2 and Mode 3 are only supported in frequency bands above 6 GHz.

[0086] In one possible implementation, each multiplexing mode may have a set of supported parameter set combinations {SSB SCS, PDCCH SCS}. For example, a set of parameter set combinations {SSB SCS, PDCCH SCS} supported by mode 1 in frequency bands below 6 GHz may include {15 kHz, 15 kHz}, {15 kHz, 30 kHz}, {30 kHz, 15 kHz}, and {30 kHz, 30 kHz}, and a set of parameter set combinations {SSB SCS, PDCCH SCS} supported by mode 1 in frequency bands above 6 GHz may include {120 kHz, 60 kHz}, {120 kHz, 120 kHz}, {240 kHz, 60 kHz}, and {240 kHz, 120 kHz}. Similarly, a set of parameter set combinations {SSB SCS, PDCCH SCS} supported by mode 2 in the frequency band above 6 GHz may include {120 kHz, 60 kHz} and {240 kHz, 120 kHz}, and a set of parameter set combinations {SSB SCS, PDCCH SCS} supported by mode 3 in the frequency band above 6 GHz may include {120 kHz, 120 kHz}.

[0087] According to some possible embodiments, the Type 0-PDCCH common search space (C-SS) may be a search space used for system information block 1 (SIB1) scheduling. The configuration of the Type 0-PDCCH C-SS is specified in Section 13 of 3GPP TS 38.213. In addition, 3GPP TS 38.213 also defines some PDCCH monitoring opportunities and related configurations (such as monitoring period, monitoring window, etc.) for Mode 1, Mode 2, and Mode 3.

[0088] FIG3 also shows the relationship between the bandwidth of a PDSCH and the bandwidth of a CORESET including a PDCCH that schedules the PDSCH.

[0089] In one possible implementation, the initial active downlink (DL) bandwidth part (BWP) can be defined as the frequency location and bandwidth of CORESET 0 and a parameter set of system information. The PDSCH delivering system information can be restricted to the initial active DL BWP. The UE can learn specific resource configurations (such as time domain and / or frequency domain resource allocation) from downlink control information (DCI). DCI can be used to schedule SIB1 for paging, random access, etc.

[0090] In one possible implementation, the DCI size may be predefined and constant for all SSB and CORESET 0 multiplexing modes. For example, the DCI may have the same size as DCI format 1_0. The DCI carried by the PDCCH in the CORESET configured by the PBCH may include indication information about time domain resource allocation, for example, one or more bits indicating time domain resource allocation.

[0091] For different multiplexing modes between the SSB and CORESET 0, the total number of bits indicating time domain resource allocation may be different. For multiplexing modes 2 and 3, if it is assumed that the PDSCH is time-aligned with the SSB, the time domain resource allocation bits may not be necessary. In addition, for different multiplexing modes between the SSB and CORESET 0, there may be different requirements for the number of time domain resource allocation bits in the DCI. For example, for multiplexing modes 2 and 3, the number of time domain resource allocation bits in the DCI carried by the PDCCH in CORESET 0 may be smaller than that for multiplexing mode 1. On the other hand, for multiplexing modes 2 and 3, if the PDSCH is always scheduled to be time-aligned with the associated SSB, this may directly limit the flexibility of time domain resource allocation. Therefore, it may be necessary to introduce an effective solution to more efficiently configure and utilize the indication information of time domain resource allocation.

[0092] In the solutions proposed in some possible embodiments, the network device may provide indication information of time domain resource allocation to the terminal device. For example, for various multiplexing modes between SSB and CORESET 0, indication information such as one or more bits may be included in the time domain resource allocation field in the DCI carried by the PDCCH in CORESET 0. For a specified multiplexing mode (e.g., multiplexing mode 2 and / or mode 3), some or all of the time domain resource allocation bits may be reused for purposes other than indicating time domain resource allocation. Optionally, at least a portion of the time domain resource allocation bits may also be used together with one or more other indicators in the DCI carried by the PDCCH in CORESET 0 (e.g., one or more reserved bits / code points, one or more bits / code points in use, etc.) to indicate other information.

[0093] In one possible implementation, in a wireless communication network such as 5G / NR, a UE-specific radio resource control (RRC) message with a bitmap may be used to indicate the SSBs actually transmitted. To determine the set of SSBs actually transmitted, the UE may need to obtain system information and / or RRC messages containing the bitmap of the SSBs actually transmitted. In addition, the UE may also need to know the SSB burst set period based on the system information and / or RRC messages.

[0094] In one 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 the SSBs actually transmitted. This can enable the UE to know which SSB set is actually transmitted before the UE obtains the system information and RRC message containing the bitmap of the SSBs actually transmitted. Optionally or additionally, at least a portion of the indication information about the time domain resource allocation can be used to indicate the SSB burst set period, so that when the UE cannot obtain the SSB burst set period according to the system information and RRC message within the SSB burst set period, the UE can know the duration of an SSB burst set.

[0095] In one 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 the 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 (for example, 4 time domain resource allocation bits) can also be used as an indication of one or more SSBs that are not transmitted.

[0096] It should be noted that some embodiments of the present disclosure are described with respect to 5G or NR systems, which are used as non-limiting examples of specific exemplary network configurations and system deployments.

[0097] Figure 4 is a flow chart of a communication processing method provided in an embodiment of the present application. The method shown in Figure 4 may be performed by the aforementioned network device. Alternatively, the method shown in Figure 4 may be performed by a chip within the network device, which is not limited in the present embodiment.

[0098] S401. Determine a first time domain resource allocation for a low power consumption signal.

[0099] The first time domain resource allocation of the low power consumption 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.

[0100] The synchronization signal block can be a synchronization signal and physical broadcast channel block (Synchronization Signal and PBCH Block, SSB), or any suitable signal block that can facilitate the terminal device to synchronize with the network device and access the network device. This application does not limit the name.

[0101] The second time domain resource allocation of SSB and the third time domain resource allocation of CORESET 0 have been allocated according to the application scenario and service requirements of the communication system. In other words, the second time domain resource allocation of SSB and the third time domain resource allocation of CORESET 0 each have corresponding time domain resources.

[0102] In one possible implementation, the network device may determine the first time domain resource allocation of the low power signal according to the indication of the higher 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.

[0103] In one possible implementation, the network device can independently determine the first time domain resource allocation of the low-power signal based on the application scenario and business requirements of the communication system, so that the first time domain resource allocation of the low-power signal is associated with the second time domain resource allocation of SSB and the third time domain resource allocation of CORESET 0.

[0104] In one possible implementation, the network device may convey indication information associated with the second time domain resource allocation of SSB and the third time domain resource allocation of CORESET 0 to the terminal device, wherein at least a portion 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 resources of the low power signal are different from the frequency domain resources of SSB and CORESET 0.

[0105] Specifically, after the network device determines the first time domain resource allocation for the low power signal, it can convey indication information associated with the second time domain resource allocation for the SSB and the third time domain resource allocation for CORESET 0 to the terminal device to indicate the first time domain resource allocation for the low power signal to the terminal device. At least a portion of the indication information is allowed to at least partially indicate the first time domain resource allocation for the low power signal. For example, at least a portion of the existing indication information can be reused or a reserved portion in the existing indication information can be used to indicate the first time domain resource allocation for the low power signal. In addition, in order not to interfere with the SSB and CORESET 0, 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.

[0106] For example, see Figure 5, which is a diagram illustrating an example of time-frequency resource allocation for a low-power signal, SSB, and CORESET 0 provided in an embodiment of the present application. As shown in Figure 5, in the three multiplexing modes of SSB and CORESET 0, the first time-domain resource allocation for the low-power signal can be associated with the second time-domain resource allocation for SSB and the third time-domain resource allocation for CORESET 0, and the frequency-domain resources for the low-power signal are different from the frequency-domain resources for SSB and CORESET 0.

[0107] In one possible implementation, CORESET 0 scheduling indicates a system information block, the system information block has a fourth time domain resource allocation, and 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 time domain resources corresponding to the third time domain resource allocation, and the time domain resources corresponding to the fourth time domain resource allocation.

[0108] Specifically, the DCI in CORESET 0 can schedule an indication system information block, such as SIB1. Generally speaking, SIB1 is carried by 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 time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1.

[0109] In this application, a subset of a set includes the empty set and the set itself.

[0110] Optionally, the set of time domain resources corresponding to the first time domain resource allocation for the low-power signal may be an empty set, indicating that no time domain resources are allocated for the low-power signal. In other words, the low-power signal is not transmitted in the set of time domain resources corresponding to the second time domain resource allocation for the SSB, the time domain resources corresponding to the third time domain resource allocation for CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation for SIB1.

[0111] 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 time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1. Referring to FIG5 , for the three multiplexing modes of SSB and CORESET 0, the PDSCH in the three multiplexing modes can all carry SIB1 indicated by the DCI scheduling 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 time domain resources of CORESET 0, and the time domain resources of the PDSCH carrying SIB1. In other words, the symbol positions occupied by the low-power signal may 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, low-power signals are transmitted on all time domain resources corresponding to the set of time domain resources corresponding to the second time domain resource allocation of SSB, the time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1.

[0112] 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 time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1. That is to say, among the time domain resources corresponding to the set of time domain resources corresponding to the second time domain resource allocation of the SSB, the time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1, only some of the time domain resources are configured for transmission of the low-power signal.

[0113] 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.

[0114] Referring to Figure 5 , for Mode 2 and Mode 3 of 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 time domain resources of CORESET 0. In other words, the symbol positions occupied by the low-power signal can be aligned in time resources only with the symbol positions occupied by the SSB and the symbol positions occupied by CORESET 0.

[0115] Optionally, the set of time domain resources corresponding to the first time domain resource allocation for the low-power signal may be an empty set, indicating that no time domain resources are allocated for the low-power signal. In other words, the low-power signal is not transmitted in the set of time domain resources corresponding to the second time domain resource allocation for the SSB and the set of time domain resources corresponding to the third time domain resource allocation for CORESET 0.

[0116] 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 and the set of time domain resources corresponding to the third time domain resource allocation of CORESET 0, for example, as shown in Mode 2 and Mode 3 of Figure 5. 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 and the third time domain resource allocation of CORESET 0.

[0117] 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 time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1. That is, among 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 time domain resources corresponding to the third time domain resource allocation of CORESET 0, only some of the time domain resources are configured for transmission of the low-power signal.

[0118] In a possible implementation, the low power consumption signal may include a low power consumption synchronization signal, and the time domain resources of the low power consumption synchronization signal may be at least the same as at least part of the time domain resources corresponding to the second time domain resource allocation.

[0119] 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 the network device, so that the LP-WUR can receive the LP-WUS to wake up the MR. This application does not limit the name of the low power synchronization signal.

[0120] 6 , the time domain resources of the LP-SS may be at least the same as at least a portion of the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0121] Optionally, the time domain resources of the LP-SS may be the same as part of the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0122] For example, in the three multiplexing modes of SSB and CORESET 0, LP-SS can occupy some symbol positions of SSB, as shown in (6b) and (6f) in Figure 6 (this situation in mode 2 is not shown).

[0123] Optionally, the time domain resources of the LP-SS may be the same as the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0124] For example, in the three multiplexing modes of SSB and CORESET 0, LP-SS can occupy the symbol position of SSB, as shown in (6a), (6c), and (6d) in Figure 6 (this situation in mode 3 is not shown).

[0125] Optionally, the time domain resources of the LP-SS may be at least the same as the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0126] For example, in mode 2 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy the symbol position of SSB and the symbol position of CORESET 0, as shown in (6e) in FIG6 .

[0127] In other words, in Mode 1 and Mode 3 of the three multiplexing modes of SSB and CORESET 0, LP-SS can occupy at least part of the position of the SSB symbol; in Mode 2, LP-SS can occupy at least part of the position of the SSB symbol and at least part of the position of the CORESET 0 symbol.

[0128] For example, the second time domain resource allocation of 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 SSB and CORESET 0, LP-SS may occupy the time domain resources corresponding to any combination of 1 to 4 symbols of the 4 symbols of SSB; and in Mode 2 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy the time domain resources corresponding to any combination of 1 to 6 symbols of a total of 6 symbols, namely, the 4 symbols of SSB and the 2 symbols of CORESET 0 (this application does not limit whether the symbols are continuous).

[0129] Furthermore, for the three multiplexing modes, LP-SS can correspond to beams one-to-one. That is, when certain SSBs are determined not to be transmitted, LP-SS is not transmitted on the corresponding time domain resources.

[0130] For multiplexing mode 1, LP-SS can also be repeatedly detected at the location of SIB1. In addition, the number of repeated checks and / or detection conditions can be configured, and the configuration information can be pre-set or indicated by the master information block (MIB).

[0131] In a possible implementation, the low power consumption signal may include an 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.

[0132] 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.

[0133] 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.

[0134] For example, in Mode 2 and Mode 3 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy some symbol positions of CORESET 0, as shown in (7c) of FIG7 (this case in Mode 2 is not shown).

[0135] 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.

[0136] For example, in Mode 2 and Mode 3 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy the symbol position of CORESET 0, as shown in (7a) of FIG7 (this case is not shown in Mode 3).

[0137] Optionally, the time domain resources of the LP-SS may be at least the same as the time domain resources corresponding to the third time domain resource allocation of CORESET 0.

[0138] For example, in Mode 2 and Mode 3 of the three multiplexing modes of SSB and CORESET 0, LP-SS can occupy the symbol position of SSB and the symbol position of CORESET 0, as shown in (7b) in Figure 7 (this case in Mode 3 is not shown).

[0139] In other words, in Mode 2 and Mode 3 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy at least part of the positions of the symbols of CORESET 0 and at least part of the positions of the symbols of SSB.

[0140] For example, the second time domain resource allocation of 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 2 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy the time domain resources corresponding to any combination of 1 to 6 symbols of the 4 symbols of SSB and 2 symbols of CORESET 0, a total of 6 symbols; and in mode 3 of the three multiplexing modes of SSB and CORESET 0, since the symbols of CORESET 0 and SSB are aligned in the time domain, LP-SS may occupy the time domain resources corresponding to any combination of 1 to 4 symbols of the 4 symbols of SSB (this application does not limit whether the symbols are continuous).

[0141] In one possible implementation, the low-power signal also includes an LP-WUS, the frequency domain resources of the LP-WUS may be the same as the frequency domain resources 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 time domain resources corresponding to the first time domain resource allocation of the low-power signal, excluding the time domain resources of the LP-SS.

[0142] LP-WUS can be other low-power signals as shown in Figures 6 and 7. When the frequency domain resources of LP-WUS are the same as the frequency domain resources of LP-SS, as shown in (6a), (6b), (6d), (6f) in Figure 6 and (7a) and (7c) in Figure 7, LP-WUS and LP-SS can be configured in a time division multiplexing (TDM) manner, and LP-WUS can occupy part 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, except the time domain resources of LP-SS (this application does not limit whether the symbols are continuous).

[0143] In one possible implementation, the low-power signal also includes an LP-WUS, the frequency domain resources of the LP-WUS may be different from the frequency domain resources 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 time domain resources corresponding to the first time domain resource allocation of the low-power signal, excluding the time domain resources of the LP-SS.

[0144] When the frequency domain resources of LP-WUS are different from the frequency domain resources of LP-SS (that is, LP-WUS and LP-SS are configured in a frequency division multiplexing (FDM) manner), LP-WUS can occupy part 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).

[0145] Optionally, the time domain resources of the LP-WUS are at least part 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 the LP-SS. That is, during the transmission of the LP-SS, the LP-WUS is not transmitted.

[0146] For mode 1 of the three multiplexing modes, the time domain resource configuration of the LP-WUS must also meet the Type 0-PDCCH C-SS configuration for mode 1 in 3GPP TS 38.213, so that the LP-WUS can be transmitted under appropriate PDCCH monitoring timing and related configurations (such as monitoring period, monitoring window, etc.).

[0147] In a possible implementation, the low power consumption signal may include an LP-WUS, and the time domain resources of the LP-WUS may be the same as at least part of the time domain resources corresponding to the first time domain resource allocation.

[0148] Refer to FIG8 , which is an example diagram of time domain resource allocation of a low power consumption wake-up signal (LP-WUS) provided in an embodiment of the present application.

[0149] In the three multiplexing modes of SSB and CORESET 0, the time domain resources of the 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 the 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, (8a) to (8f) in Figure 8. Furthermore, the time domain resources of the LP-WUS can be discontinuous, for example, (8b) and (8e) in Figure 8.

[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, in this case, all time domain resources corresponding to the first time domain resource allocation can be used for LP-WUS transmission.

[0151] In a possible implementation manner, the time domain resources of the LP-WUS are at least the same as at least a portion of the time domain resources corresponding to the second time domain resource allocation.

[0152] In the three multiplexing modes of SSB and CORESET 0, the time domain resources of the 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 the 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, (8a), (8c), (8d), and (8f) in Figure 8. Furthermore, the time domain resources of the LP-WUS can be discontinuous, for example, (8e) in Figure 8.

[0153] It is easy to understand that when the time domain resources of the LP-WUS are a non-empty subset of the set of time domain resources corresponding to the second time domain resource allocation, the LP-WUS may correspond to the SSB.

[0154] In a possible implementation, the LP-WUS may be associated with a user equipment group (UE group), wherein an index of the user equipment group is associated with an index of an SSB corresponding to a time domain resource of the LP-WUS.

[0155] Specifically, the user equipment group may be a plurality of UEs grouped according to a specific standard.

[0156] Optionally, considering different locations of UEs, UEs with the same beam or related beams may be in one group, that is, the user equipment groups may be divided according to beams.

[0157] Optionally, UE groups may be divided according to the time slot structure type, and different parameter sets (numerologies) or services may be placed in different groups.

[0158] Optionally, UEs with different processing capabilities may be grouped according to supported bandwidth ranges.

[0159] This application does not limit the grouping method of user equipment groups.

[0160] The LP-WUS may be a paging message for a user equipment group. Since the LP-WUS may correspond to an SSB within an SSB burst set period (e.g., 20 ms), the LP-WUS may be configured for a specific user equipment group based on the SSB index. In other words, the SSB index may correspond to the user equipment group index. Based on the SSB index corresponding to the time domain resource of the LP-WUS, the LP-WUS may be configured as a paging message for the user equipment group having the corresponding user equipment group index.

[0161] In one possible implementation, one SSB may correspond to one user equipment group.

[0162] Optionally, the index of the SSB can be matched with the index of the user device group based on a hash function, and the correspondence between the index of the SSB and the index of the user device group can be updated according to the SSB burst set period (i.e., the beam scanning period), so that the user device group can traverse all beams.

[0163] 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 Index of SSB _UE group is the index of the user equipment group in the current beam scanning period, N _UE group is the number of user equipment groups, a can be less than N _UE group And with N _UE group Any mutually prime positive integers, so that the user equipment group can traverse all beams.

[0164] In one possible implementation, multiple SSBs may correspond to one user equipment group.

[0165] Optionally, multiple SSBs in an SSB burst set period may correspond to one user equipment group, so that LP-WUS may be repeatedly sent to a specific user equipment group at multiple SSB time domain positions, or LP-WUS may be sent using longer time domain symbols.

[0166] In one possible implementation, an SSB burst set may be associated with a user equipment group, that is, all SSBs in an SSB burst set period may correspond to a specific user equipment group, so that within one SSB burst set period (e.g., 20 ms), the specific user equipment group may scan all beams.

[0167] Optionally, the starting position of the SSB burst set period may be the beginning of a period of connected mode discontinuous reception (CDRX) or extended / enhanced discontinuous reception (EDRX).

[0168] In one possible implementation, the first time domain resource allocation of the low power consumption signal is also associated with the time domain resource allocation of the tracking reference signal (TRS). The method also includes: sending the TRS to the terminal device so that the terminal device determines the first time domain resource allocation of the low power consumption signal based on the time domain resource allocation of the TRS.

[0169] Optionally, the symbol position of the LP-SS or the symbol position of the LP-WUS can be determined based on the symbol position of the TRS. For example, the symbol position of the LP-SS or the symbol position of the LP-WUS can be the same as the symbol position of the TRS, or separated by a predefined offset value.

[0170] In the method described in Figure 4, 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 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 SSB and CORESET 0, which can reduce the additional time domain resource overhead and reduce the system energy saving gain loss.

[0171] Figure 9 is a flow chart of a communication processing method provided in an embodiment of the present application. The method shown in Figure 9 may be executed by the terminal device mentioned above. Alternatively, the method shown in Figure 9 may be executed by a chip in the terminal device, which is not limited in the present embodiment. Figure 9 illustrates the method using a terminal device as an example.

[0172] S901. Determine a first time domain resource allocation for a low power consumption signal.

[0173] The first time domain resource allocation of the low power consumption 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.

[0174] The synchronization signal block can be a synchronization signal and physical broadcast channel block (Synchronization Signal and PBCH Block, SSB), or any suitable signal block that can facilitate the terminal device to synchronize with the network device and access the network device. This application does not limit the name.

[0175] The second time domain resource allocation of SSB and the third time domain resource allocation of CORESET 0 have been allocated according to the application scenario and service requirements of the communication system. In other words, the second time domain resource allocation of SSB and the third time domain resource allocation of CORESET 0 each have corresponding time domain resources.

[0176] In one possible implementation, the terminal 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.

[0177] In one possible implementation, the terminal device can determine the first time domain resource allocation of the low power signal by itself according to a predefined configuration, so that the first time domain resource allocation of the low power signal is associated with the second time domain resource allocation of SSB and the third time domain resource allocation of CORESET 0.

[0178] In one possible implementation, the terminal device may receive indication information associated with the second time domain resource allocation of SSB and the third time domain resource allocation of CORESET 0 from the network device to determine the first time domain resource allocation of the low power consumption signal, wherein at least a portion of the indication information is allowed to at least partially indicate the first time domain resource allocation of the low power consumption signal, and the frequency domain resources of the low power consumption signal are different from the frequency domain resources of SSB and CORESET 0.

[0179] Specifically, after the network device determines the first time domain resource allocation for the low power signal, it can convey indication information associated with the second time domain resource allocation for the SSB and the third time domain resource allocation for CORESET 0 to the terminal device to indicate the first time domain resource allocation for the low power signal to the terminal device. The terminal device can determine the first time domain resource allocation for the low power signal based on the indication information. At least a portion of the indication information is allowed to at least partially indicate the first time domain resource allocation for the low power signal. For example, at least a portion of the existing indication information can be reused or a reserved portion in the existing indication information can be used to indicate the first time domain resource allocation for the low power signal. In addition, in order not to interfere with the SSB and CORESET 0, 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.

[0180] For example, see Figure 5, which shows an example of time-frequency resource allocation for a low-power signal, SSB, and CORESET 0 provided in an embodiment of the present application. As shown in Figure 5, in the three multiplexing modes of SSB and CORESET 0, the first time-domain resource allocation for the low-power signal can be associated with the second time-domain resource allocation for SSB and the third time-domain resource allocation for CORESET 0, and the frequency-domain resources for the low-power signal are different from the frequency-domain resources for SSB and CORESET 0.

[0181] In one possible implementation, CORESET 0 scheduling indicates a system information block, the system information block has a fourth time domain resource allocation, and 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 time domain resources corresponding to the third time domain resource allocation, and the time domain resources corresponding to the fourth time domain resource allocation.

[0182] Specifically, the DCI in CORESET 0 can schedule an indication system information block, such as SIB1. Generally speaking, SIB1 is carried by 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 time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1.

[0183] In this application, a subset of a set includes the empty set and the set itself.

[0184] Optionally, the set of time domain resources corresponding to the first time domain resource allocation for the low-power signal may be an empty set, indicating that no time domain resources are allocated for the low-power signal. In other words, the low-power signal is not transmitted in the set of time domain resources corresponding to the second time domain resource allocation for the SSB, the time domain resources corresponding to the third time domain resource allocation for CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation for SIB1.

[0185] 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, the time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1. Referring to Figure 5 , for the three multiplexing modes of SSB and CORESET 0, the PDSCH in all three multiplexing modes can carry SIB1 indicated by the DCI scheduling in CORESET 0. The set of time domain resources allocated to the low-power signal can be the same as the set of time domain resources of the SSB, the time domain resources of CORESET 0, and the 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, low-power signals are transmitted on all time domain resources corresponding to the set of time domain resources corresponding to the second time domain resource allocation of SSB, the time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1.

[0186] 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 time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1. That is to say, among the time domain resources corresponding to the set of time domain resources corresponding to the second time domain resource allocation of the SSB, the time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1, only some of the time domain resources are configured for transmission of the low-power signal.

[0187] 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.

[0188] Referring to Figure 5 , for Mode 2 and Mode 3 of 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 time domain resources of CORESET 0. In other words, the symbol positions occupied by the low-power signal can be aligned in time resources only with the symbol positions occupied by the SSB and the symbol positions occupied by CORESET 0.

[0189] Optionally, the set of time domain resources corresponding to the first time domain resource allocation for the low-power signal may be an empty set, indicating that no time domain resources are allocated for the low-power signal. In other words, the low-power signal is not transmitted in the set of time domain resources corresponding to the second time domain resource allocation for the SSB and the set of time domain resources corresponding to the third time domain resource allocation for CORESET 0.

[0190] 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 and the set of time domain resources corresponding to the third time domain resource allocation of CORESET 0, for example, as shown in Mode 2 and Mode 3 of Figure 5. 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 and the third time domain resource allocation of CORESET 0.

[0191] 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 time domain resources corresponding to the third time domain resource allocation of CORESET 0, and the time domain resources corresponding to the fourth time domain resource allocation of SIB1. That is, among 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 time domain resources corresponding to the third time domain resource allocation of CORESET 0, only some of the time domain resources are configured for transmission of the low-power signal.

[0192] In a possible implementation, the low power consumption signal may include a low power consumption synchronization signal, and the time domain resources of the low power consumption synchronization signal may be at least the same as at least part of the time domain resources corresponding to the second time domain resource allocation.

[0193] 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 the network device, so that the LP-WUR can receive the LP-WUS to wake up the MR. This application does not limit the name of the low power synchronization signal.

[0194] 6 , the time domain resources of the LP-SS may be at least the same as at least a portion of the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0195] Optionally, the time domain resources of the LP-SS may be the same as part of the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0196] For example, in the three multiplexing modes of SSB and CORESET 0, LP-SS can occupy some symbol positions of SSB, as shown in (6b) and (6f) in Figure 6 (this situation in mode 2 is not shown).

[0197] Optionally, the time domain resources of the LP-SS may be the same as the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0198] For example, in the three multiplexing modes of SSB and CORESET 0, LP-SS can occupy the symbol position of SSB, as shown in (6a), (6c), and (6d) in Figure 6 (this situation in mode 3 is not shown).

[0199] Optionally, the time domain resources of the LP-SS may be at least the same as the time domain resources corresponding to the second time domain resource allocation of the SSB.

[0200] For example, in mode 2 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy the symbol position of SSB and the symbol position of CORESET 0, as shown in (6e) in FIG6 .

[0201] In other words, in Mode 1 and Mode 3 of the three multiplexing modes of SSB and CORESET 0, LP-SS can occupy at least part of the position of the SSB symbol; in Mode 2, LP-SS can occupy at least part of the position of the SSB symbol and at least part of the position of the CORESET 0 symbol.

[0202] For example, the second time domain resource allocation of 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 SSB and CORESET 0, LP-SS may occupy the time domain resources corresponding to any combination of 1 to 4 symbols of the 4 symbols of SSB; and in Mode 2 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy the time domain resources corresponding to any combination of 1 to 6 symbols of a total of 6 symbols, namely, the 4 symbols of SSB and the 2 symbols of CORESET 0 (this application does not limit whether the symbols are continuous).

[0203] Furthermore, for the three multiplexing modes, LP-SS can correspond to beams one-to-one. That is, when certain SSBs are determined not to be transmitted, LP-SS is not transmitted on the corresponding time domain resources.

[0204] For multiplexing mode 1, LP-SS can also be repeatedly detected at the location of SIB1. In addition, the number of repeated checks and / or detection conditions can be configured, and the configuration information can be pre-set or indicated by the master information block (MIB).

[0205] In a possible implementation, the low power consumption signal may include an 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.

[0206] 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.

[0207] 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.

[0208] For example, in Mode 2 and Mode 3 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy some symbol positions of CORESET 0, as shown in (7c) of FIG7 (this case in Mode 2 is not shown).

[0209] 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.

[0210] For example, in Mode 2 and Mode 3 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy the symbol position of CORESET 0, as shown in (7a) of FIG7 (this case is not shown in Mode 3).

[0211] Optionally, the time domain resources of the LP-SS may be at least the same as the time domain resources corresponding to the third time domain resource allocation of CORESET 0.

[0212] For example, in Mode 2 and Mode 3 of the three multiplexing modes of SSB and CORESET 0, LP-SS can occupy the symbol position of SSB and the symbol position of CORESET 0, as shown in (7b) in Figure 7 (this case in Mode 3 is not shown).

[0213] In other words, in Mode 2 and Mode 3 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy at least part of the positions of the symbols of CORESET 0 and at least part of the positions of the symbols of SSB.

[0214] For example, the second time domain resource allocation of 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 2 of the three multiplexing modes of SSB and CORESET 0, LP-SS may occupy the time domain resources corresponding to any combination of 1 to 6 symbols of the 4 symbols of SSB and 2 symbols of CORESET 0, a total of 6 symbols; and in mode 3 of the three multiplexing modes of SSB and CORESET 0, since the symbols of CORESET 0 and SSB are aligned in the time domain, LP-SS may occupy the time domain resources corresponding to any combination of 1 to 4 symbols of the 4 symbols of SSB (this application does not limit whether the symbols are continuous).

[0215] In one possible implementation, the low-power signal also includes an LP-WUS, the frequency domain resources of the LP-WUS may be the same as the frequency domain resources 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 time domain resources corresponding to the first time domain resource allocation of the low-power signal, excluding the time domain resources of the LP-SS.

[0216] LP-WUS can be other low-power signals as shown in Figures 6 and 7. When the frequency domain resources of LP-WUS are the same as the frequency domain resources of LP-SS, as shown in (6a), (6b), (6d), (6f) in Figure 6 and (7a) and (7c) in Figure 7, LP-WUS and LP-SS can be configured in a time division multiplexing (TDM) manner, and LP-WUS can occupy part 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, except the time domain resources of LP-SS (this application does not limit whether the symbols are continuous).

[0217] In one possible implementation, the low-power signal also includes an LP-WUS, the frequency domain resources of the LP-WUS may be different from the frequency domain resources 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 time domain resources corresponding to the first time domain resource allocation of the low-power signal, excluding the time domain resources of the LP-SS.

[0218] When the frequency domain resources of LP-WUS are different from the frequency domain resources of LP-SS (that is, LP-WUS and LP-SS are configured in a frequency division multiplexing (FDM) manner), LP-WUS can occupy part 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).

[0219] Optionally, the time domain resources of the LP-WUS are at least part 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 the LP-SS. That is, during the transmission of the LP-SS, the LP-WUS is not transmitted.

[0220] For mode 1 of the three multiplexing modes, the time domain resource configuration of the LP-WUS must also meet the Type 0-PDCCH C-SS configuration for mode 1 in 3GPP TS 38.213, so that the LP-WUS can be transmitted under appropriate PDCCH monitoring timing and related configurations (such as monitoring period, monitoring window, etc.).

[0221] In a possible implementation, the low power consumption signal may include an LP-WUS, and the time domain resources of the LP-WUS may be the same as at least part of the time domain resources corresponding to the first time domain resource allocation.

[0222] Refer to FIG8 , which is an example diagram of time domain resource allocation of a low power consumption wake-up signal (LP-WUS) provided in an embodiment of the present application.

[0223] In the three multiplexing modes of SSB and CORESET 0, the time domain resources of the 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 the 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, (8a) to (8f) in Figure 8. Furthermore, the time domain resources of the LP-WUS can be discontinuous, for example, (8b) and (8e) in Figure 8.

[0224] 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, in this case, all time domain resources corresponding to the first time domain resource allocation can be used for LP-WUS transmission.

[0225] In a possible implementation manner, the time domain resources of the LP-WUS are at least the same as at least a portion of the time domain resources corresponding to the second time domain resource allocation.

[0226] In the three multiplexing modes of SSB and CORESET 0, the time domain resources of the 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 the 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, (8a), (8c), (8d), and (8f) in Figure 8. Furthermore, the time domain resources of the LP-WUS can be discontinuous, for example, (8e) in Figure 8.

[0227] It is easy to understand that when the time domain resources of the LP-WUS are a non-empty subset of the set of time domain resources corresponding to the second time domain resource allocation, the LP-WUS may correspond to the SSB.

[0228] In a possible implementation, the LP-WUS may be associated with a user equipment group (UE group), wherein an index of the user equipment group is associated with an index of an SSB corresponding to a time domain resource of the LP-WUS.

[0229] Specifically, the user equipment group may be a plurality of UEs grouped according to a specific standard.

[0230] Optionally, considering different locations of UEs, UEs with the same beam or related beams may be in one group, that is, the user equipment groups may be divided according to beams.

[0231] Optionally, UE groups may be divided according to the time slot structure type, and different parameter sets (numerologies) or services may be placed in different groups.

[0232] Optionally, UEs with different processing capabilities may be grouped according to supported bandwidth ranges.

[0233] This application does not limit the grouping method of user equipment groups.

[0234] The LP-WUS may be a paging message for a user equipment group. Since the LP-WUS may correspond to an SSB within an SSB burst set period (e.g., 20 ms), the LP-WUS may be configured for a specific user equipment group based on the SSB index. In other words, the SSB index may correspond to the user equipment group index. Based on the SSB index corresponding to the time domain resource of the LP-WUS, the LP-WUS may be configured as a paging message for the user equipment group having the corresponding user equipment group index.

[0235] In one possible implementation, one SSB may correspond to one user equipment group.

[0236] Optionally, the index of the SSB can be matched with the index of the user device group based on a hash function, and the correspondence between the index of the SSB and the index of the user device group can be updated according to the SSB burst set period (i.e., the beam scanning period), so that the user device group can traverse all beams.

[0237] 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 Index of SSB _UE group is the index of the user equipment group in the current beam scanning period, N _UE group is the number of user equipment groups, a can be less than N _UE group And with N _UE group Any mutually prime positive integers, so that the user equipment group can traverse all beams.

[0238] In one possible implementation, multiple SSBs may correspond to one user equipment group.

[0239] Optionally, multiple SSBs in an SSB burst set period may correspond to one user equipment group, so that LP-WUS may be repeatedly sent to a specific user equipment group at multiple SSB time domain positions, or LP-WUS may be sent using longer time domain symbols.

[0240] In one possible implementation, an SSB burst set may be associated with a user equipment group, that is, all SSBs in an SSB burst set period may correspond to a specific user equipment group, so that within one SSB burst set period (e.g., 20 ms), the specific user equipment group may scan all beams.

[0241] Optionally, the starting position of the SSB burst set period may be the beginning of a period of connected mode discontinuous reception (CDRX) or extended / enhanced discontinuous reception (EDRX).

[0242] In one possible implementation, the first time domain resource allocation of the low power consumption signal is also associated with the time domain resource allocation of the tracking reference signal (TRS). The method also includes: determining that the TRS is received from the network device; and determining the first time domain resource allocation of the low power consumption signal based on the time domain resource allocation of the TRS.

[0243] Optionally, the symbol position of the LP-SS or the symbol position of the LP-WUS can be determined based on the symbol position of the TRS. For example, the symbol position of the LP-SS or the symbol position of the LP-WUS can be the same as the symbol position of the TRS, or separated by a predefined offset value.

[0244] In the method described in Figure 9, 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 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 SSB and CORESET 0, which can reduce the additional time domain resource overhead and reduce the system energy-saving gain loss.

Figure 10 uses the terminal device and network device as the execution subject of the method as an example.

[0246] S1001. The network device transmits indication information about the first time domain resource allocation of the low power consumption signal to the terminal device. Correspondingly, the terminal device receives the indication information about the first time domain resource allocation of the low power consumption signal from the network device.

[0247] It is easy to understand that step S1001 can refer to the description of the indication information of the first time domain resource allocation of the low power signal in the above step S401 on the network device and step S901 on the terminal device, and will not be repeated here.

The communication device 1100 shown in Figure 11 can be a terminal device, or a device in a terminal device, or a device that can be used in combination with a terminal device; or the communication device shown in Figure 11 can be a network device, or a device in a network device, or a device that can be used in combination with a network device. The communication device 1100 shown in Figure 11 may include a communication unit 1101 and a processing unit 1102. Specifically, the processing unit 1102 is used to process data, which may be data received by the communication unit 1101, and the processed data may also be sent by the communication unit 1101.

[0249] Specifically, the processing unit 1102 is configured to execute the data processing function of the terminal device or network device in the aforementioned method embodiment. For other possible implementations of the communication device, reference can be made to the description of the terminal device or network device functions in the method embodiment corresponding to FIG. 4 or FIG. 9 above, which will not be repeated here.
