[0137] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are examples. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0138] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0139] In some embodiments of the present disclosure, the terminal device shown in FIG1 may be a terminal device that supports a power saving function. For example, when no data is being sent or received, the terminal device may be in a sleep state of varying degrees. In one implementation, the sleep state of the terminal device may include at least one of ultra-deep sleep, deep sleep, light sleep, and micro sleep.
[0140] In some embodiments, the terminal device may be a terminal device that supports a low-power wake-up signal LP WUS. In a power-saving state, the terminal device may put the main MR into a sleep state and turn on a receiver that supports receiving LP WUS, which may be referred to as LP-WUR. If the LP-WUR detects an LP-WUS for the terminal device, the MR may be turned on and normal data transmission may be performed. If the LP-WUR does not detect an LP-WUS signal for the terminal device, or the LP-WUS indicates not to wake up the terminal, the terminal device will maintain the current sleep state of the MR. In this way, the power consumption of the MR can be reduced, and since the power consumption of the LP-WUR is relatively low, the power consumption of the terminal device can be further reduced.
[0141] In some embodiments, the LP-WUS may include two parts, the first part may be a preamble, and the second part may be a message part carrying wake-up information.
[0142] In one implementation, the preamble can assist the terminal device in detecting the message portion of the LP-WUS. For example, the preamble can be used for time and frequency synchronization, and can also serve as indication information of whether the LP-WUS exists. This embodiment of the present disclosure is not limited to this.
[0143] In another implementation, the preamble may also carry information.
[0144] In some embodiments, the LP-WUS may include a message portion carrying wake-up information but not including a preamble. In this case, the terminal device may synchronize time and frequency based on other signals transmitted additionally.
[0145] In some embodiments, the terminal device needs to obtain the time and frequency position of the LP-WUS transmitted by the network device and detect the LP-WUS.
[0146] In some embodiments, terminal devices can synchronize time and frequency by detecting synchronization signals. In one implementation, the first part of the LP-WUS, the preamble, is used as the synchronization signal. Because the LP-WUS is transmitted aperiodically, the preamble is also a non-periodic synchronization signal. In another implementation, a dedicated low-power synchronization signal is periodically sent to the terminal device, which increases additional signaling overhead. Therefore, how to transmit synchronization signals and improve the terminal device's synchronization accuracy for time and frequency, so as to better detect the LP-WUS, has become an urgent problem to be solved.
[0147] FIG2A is an interactive schematic diagram of a signal transmission method according to an embodiment of the present disclosure. The method can be performed by the above-mentioned communication system. As shown in FIG2A , the method may include:
[0148] Step S2101: The network device sends a synchronization signal at at least one first resource location according to a resource cycle.
[0149] In some embodiments, the terminal device may receive a synchronization signal. For example, the terminal device may receive a synchronization signal sent by a network device. For another example, the terminal device may also receive a synchronization signal sent by another entity.
[0150] In some embodiments, each terminal device may receive a synchronization signal.
[0151] In some embodiments, the synchronization signal can be used for signal synchronization of terminal devices.
[0152] In some embodiments, signal synchronization may be synchronization of time and frequency.
[0153] In some embodiments, the synchronization signal may be the first part of the LP-WUS, ie, a preamble.
[0154] In some embodiments, the synchronization signal may also be LP-WUS.
[0155] In some embodiments, the name of the synchronization signal is not limited, for example, it can be "low power synchronization signal", "LP-WUS synchronization signal", "synchronization indication information", "low power synchronization indication information", etc.
[0156] In some embodiments, the terminal device may receive a synchronization signal at at least one first resource location. For example, the terminal device may receive a synchronization signal sent by a network device at at least one first resource location. For another example, the terminal device may also receive a synchronization signal sent by another entity at at least one first resource location.
[0157] In some embodiments, the terminal device may receive the synchronization signal at any first resource location.
[0158] In some embodiments, the first resource location may include a resource location configured by the network device that is capable of sending a synchronization signal.
[0159] In some embodiments, the first resource location may include a resource location configured by the network device that is capable of sending a low-power wake-up signal.
[0160] In some embodiments, the first resource location may be a time domain resource location.
[0161] In some embodiments, the name of the first resource location is not limited, and may be, for example, "first location", "resource location", "preamble location", "Preamble location", "location information", "location indication", etc.
[0162] In some embodiments, the resource period may also be a time period preset by the network device.
[0163] In one implementation, the time period may include multiple first resource locations, taking 4 first resource locations as an example, where 2 first resource locations may be first resource locations configured for UE1, and 2 first resource locations may be first resource locations configured for UE2.
[0164] In another implementation, the time period may correspond to a fixed duration, for example, the time period may be 100 ms.
[0165] In some embodiments, the positions where the synchronization signal can be sent according to the resource period configuration may include the union or superset of the preamble code positions of the low-power wake-up signal configured by the network device for each terminal device.
[0166] In some embodiments, the periods of the resource locations of the low-power wake-up signals corresponding to different terminal devices may be the same or different, and this is not limited in the embodiments of the present disclosure.
[0167] In some embodiments, the first resource location may include a second resource location and a third resource location, the second resource location may include a resource location that can send a preamble code of a low-power wake-up signal and cannot send wake-up information of a low-power wake-up signal, and the third resource location may include a resource location that can send a low-power wake-up signal.
[0168] In some embodiments, the first resource location may include a third resource location, and there is no limitation on whether the second resource location is included.
[0169] In some embodiments, “no limitation on whether to include the second resource location” may be interpreted as the first resource location may include the second resource location or may not include the second resource location.
[0170] FIG2B is a schematic diagram illustrating a signal transmission according to an embodiment of the present disclosure. As shown in FIG2B , the first resource locations configured by the network device within a resource cycle may include first resource locations configured for UE1 and UE2, as well as first resource locations not configured for terminal devices. For ease of explanation, the first resource locations shown in FIG2B are denoted as A, B, C, D, E, and F. The resource location indicated by UE1 represents a resource location configured by the network device for UE1 that can send a low-power wake-up signal, i.e., the first resource locations indicated by A and D in FIG2B are third resource locations. The resource location indicated by UE2 represents a resource location configured by the network device for UE2 that can send a low-power wake-up signal, and the first resource locations indicated by B and E in FIG2B are also third resource locations. NO UE indicates that the network device has not configured a low-power wake-up signal for the terminal device at this resource location, and wake-up of the terminal device is not required. A synchronization signal, i.e., the first part of the low-power wake-up signal, can be sent, and wake-up information for the low-power wake-up signal is not sent. i.e., the first resource location indicated by C in FIG2B is a second resource location.
[0171] In some embodiments, for a first resource location that is not configured with a terminal device, the first resource location may include a resource location that can send a preamble code of a low-power wake-up signal and a resource location that can send wake-up information of a low-power wake-up signal. The network device can send a preamble code of a low-power wake-up signal at the first resource location, but not send wake-up information of a low-power wake-up signal.
[0172] In other embodiments, for a first resource location where a terminal device is not configured, the first resource location may include a resource location that can send a preamble code of a low-power wake-up signal, but does not include a resource location that can send wake-up information of a low-power wake-up signal. The network device may send a preamble code of a low-power wake-up signal at the first resource location.
[0173] In some embodiments, the network device may send a synchronization signal at at least one of the second resource location and the fourth resource location according to the resource cycle. The fourth resource location may include a resource location in the third resource location except the fifth resource location. The fifth resource location may be a resource location configured by the network device for the first terminal device to be awakened; and a low-power wake-up signal is sent at the fifth resource location.
[0174] In some embodiments, the network device may send a synchronization signal at each first resource position within a resource period.
[0175] In some embodiments, the network device may send synchronization signals at some first resource locations within the resource period. Taking FIG2B as an example, the network device may send synchronization signals at first resource locations indicated by B, C, and D.
[0176] In some embodiments, for each resource cycle, if the network device determines that one of the terminal devices needs to be awakened, it may send a low-power awakening signal at the first resource location corresponding to the terminal device. Taking Figure 2B as an example, if the network device determines that UE1 needs to be awakened, it may send a synchronization signal at the third resource location indicated by B, send a synchronization signal at the second resource location indicated by C, and send a low-power awakening signal at the fifth resource location indicated by D.
[0177] In this way, the network device can flexibly send the synchronization signal so that the terminal device can receive the synchronization signal at more resource locations, thereby improving the synchronization accuracy of the terminal device.
[0178] In some embodiments, the network device may send a synchronization signal at the second resource location and not send a synchronization signal at the fourth resource location according to a resource cycle.
[0179] Taking FIG. 2B as an example, the network device may send a synchronization signal at the second resource location indicated by C, and may not send a synchronization signal at the fourth resource location indicated by B.
[0180] In one implementation, if the network device determines that one of the terminal devices needs to be woken up, it may send a low-power wake-up signal at the fifth resource location corresponding to the terminal device.
[0181] FIG2C is a schematic diagram illustrating a signal transmission according to an embodiment of the present disclosure. As shown in FIG2C , the resource location marking method can be referred to the description of FIG2B and will not be repeated here. The network device sends a synchronization signal at the second resource location indicated by C, does not send a synchronization signal at the third resource location indicated by B, and if it determines that UE1 needs to be awakened, sends a low-power awakening signal at the fifth resource location indicated by D.
[0182] In some embodiments, different preamble code positions may correspond to different wake-up information positions of the low-power wake-up signal.
[0183] As shown in FIG2B , the preamble code and the wake-up information that can be sent at each first resource position are in one-to-one correspondence, that is, different preamble code positions correspond to different wake-up information positions of the low-power wake-up signal.
[0184] In some embodiments, the preamble code and the wake-up information of the low-power wake-up signal may have a preset timing relationship.
[0185] For example, the preamble and the wake-up information may occupy consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols, or the interval between the preamble and the wake-up information may be predefined or preconfigured.
[0186] In some embodiments, each preamble position corresponds to a wake-up information position of multiple low-power wake-up signals.
[0187] For example, the resource locations configured by the network device for sending preamble codes for multiple terminal devices in a group of terminal devices may be the same, and the resource locations configured for sending wake-up information for each terminal device in the group of terminal devices may be different.
[0188] In some embodiments, the timing relationship between the preamble and the wake-up information is configurable.
[0189] For example, the wake-up information of different low-power wake-up signals may be mapped to a common preamble.
[0190] In some embodiments, the wake-up information of multiple low-power wake-up information of the terminal device within a resource period can be associated with different preamble codes.
[0191] In some embodiments, the wake-up information of multiple low-power wake-up information of the terminal device within a resource period can be associated with the same preamble code.
[0192] FIG2D is a schematic diagram illustrating a signal transmission according to an embodiment of the present disclosure. As shown in FIG2D , a network device is configured with six first resource locations and low-power wake-up signals for two groups of UEs. Two groups of low-power wake-up signals are configured for the first group of UEs, and two groups of low-power wake-up signals are configured for the second group of UEs. Each group of locations includes a resource location P indicating a preamble for sending a low-power wake-up signal, and three resource locations Msg indicating wake-up information for sending the low-power wake-up signal. The three Msgs in each group of locations correspond to the same P. The first group of UEs includes three UEs, which can be represented by UE11, UE12, and UE13. The resource location indicated by Msg1 is the resource location configured by the network device for sending wake-up information for UE11, the resource location indicated by Msg2 is the resource location configured by the network device for sending wake-up information for UE12, and the resource location indicated by Msg3 is the resource location configured by the network device for sending wake-up information for UE13. The second group of UEs also includes three UEs, which can be represented by UE21, UE22, and UE23. The resource location indicated by Msg1 is the resource location configured by the network device for sending the wake-up information of UE21, the resource location indicated by Msg2 is the resource location configured by the network device for sending the wake-up information of UE22, and the resource location indicated by Msg3 is the resource location configured by the network device for sending the wake-up information of UE23. The resource location indicated by P is the resource location configured by the network device for sending the preamble code, and P indicates a different resource location for each group of UEs. In addition, the network device also configures the first resource location capable of sending synchronization signals in the resource locations of two resource locations that are not configured with terminal devices, namely the first resource location indicated by NO UE in Figure 2D.
[0193] As shown in Figure 2D, for the convenience of explanation, the six first resource locations are recorded as A, B, C, D, E, and F, where the resource locations indicated by A, C, D, and F are third resource locations, and the resource locations indicated by B and E are second resource locations. The network device can send a synchronization signal at the resource location indicated by P in A, send a synchronization signal at the resource location indicated by B, send a preamble of a low-power wake-up signal at the resource location indicated by P in C, send wake-up information of a low-power wake-up signal at the resource location indicated by Msg2 in C, indicating that the network device needs to wake up UE22 in the second group of terminal devices, send a preamble of a low-power wake-up signal at the resource location indicated by P in D, and send wake-up information of a low-power wake-up signal at the resource location indicated by Msg3 in D, indicating that the network device needs to wake up UE13 in the first group of terminal devices.
[0194] It should be noted that the synchronization signal transmission in FIG2D is for exemplary purposes only, and the embodiment of the present disclosure does not limit the first resource location at which the network device actually sends the synchronization signal.
[0195] In some embodiments, the "resource location that cannot send wake-up information of a low-power wake-up signal" can be interpreted as the first resource location including the resource location that can send a preamble code, but not including the resource location that can send wake-up information, as shown in Figure 2D. It can also be interpreted as the first resource location including the resource location that can send a preamble code of a low-power wake-up signal and the resource location that can send wake-up information of a low-power wake-up signal, as shown in Figure 2B. The network device can send the preamble code of the low-power wake-up signal at the first resource location, but not send the wake-up information of the low-power wake-up signal.
[0196] In some embodiments, the first resource location may include a third resource location.
[0197] In some embodiments, “the first resource location includes the third resource location” may be interpreted as the first resource location including the third resource location but excluding the second resource location.
[0198] In some embodiments, the network device may configure the third resource location through a bitmap.
[0199] In some embodiments, the network device configures a resource location for the terminal device that can send a low-power wake-up signal, and the bitmap of the resource location can be used to indicate that the resource location is available.
[0200] In some embodiments, if the network device does not configure a low-power wake-up signal for a terminal device at a resource location, the network device may indicate that the resource location is unavailable through a bitmap of the resource location.
[0201] In some embodiments, when sending a synchronization signal, the network device may determine a third resource location where the synchronization signal can be sent through a bitmap.
[0202] In some embodiments, for each resource period, a bitmap may also be used to indicate a third resource position within the resource period where a synchronization signal can be sent.
[0203] In some embodiments, the network device may indicate through a bitmap that a resource location where a low-power wake-up signal cannot be sent is available.
[0204] Figure 2E is a schematic diagram of a signal transmission according to an embodiment of the present disclosure. As shown in Figure 2E, the first resource location configured by the network device is used for synchronization of UE1 and UE2. The network device configures three low-power wake-up signal locations for UE1 and two low-power wake-up signal locations for UE2.
[0205] In some embodiments, the network device may send a synchronization signal at at least one fourth resource location based on a resource cycle. The fourth resource location may include a resource location in the third resource location except for the fifth resource location. The fifth resource location may be a resource location configured by the network device for the first terminal device to be awakened; and a low-power wake-up signal is sent at the fifth resource location.
[0206] In some embodiments, if the network device determines that it is not necessary to wake up any terminal device, the fourth resource location is the same as the resource location included in the third resource location.
[0207] In some embodiments, if the network device determines that it is not necessary to wake up any terminal device, it may send a synchronization signal at at least one third resource location according to the resource cycle.
[0208] As shown in Figure 2E, the network device is configured with five first resource locations. For ease of explanation, the five first resource locations are recorded as A, B, C, D, and E. The network device sends a synchronization signal at the resource location indicated by B, but does not send a synchronization signal at the resource locations indicated by A, C, D, and E. That is, the resource locations indicated by A, B, C, D, and E are all third resource locations.
[0209] In some embodiments, if the network device determines that the first terminal needs to be awakened, it may send a synchronization signal at at least one fourth resource location and send a low-power awakening signal at a fifth resource location according to a resource cycle.
[0210] Figure 2F is a schematic diagram illustrating a signal transmission according to an embodiment of the present disclosure. As shown in Figure 2F , the network device is configured with five first resource locations. For ease of explanation, the five first resource locations are denoted as A, B, C, D, and E. The network device sends a synchronization signal at the resource location indicated by B, does not send a synchronization signal at the resource locations indicated by A, D, and E, and sends a low-power wake-up signal at the resource location indicated by C. That is, the resource locations indicated by A, B, D, and E are the fourth resource locations, and the resource location indicated by C is the fifth resource location.
[0211] It should be noted that the locations for sending synchronization signals in Figures 2E and 2F are exemplary. The network device can be configured to send synchronization signals at any one or more first resource locations within the resource period. Taking Figure 2F as an example, if the network device does not wake up UE1, it may not send synchronization signals or low-power wake-up signals at the three low-power wake-up signal locations of UE1.
[0212] In some embodiments, the network device may send a synchronization signal at every third resource location.
[0213] FIG2G is a schematic diagram illustrating a signal transmission according to an embodiment of the present disclosure. As shown in FIG2G , the network device is configured with five first resource locations, which, for ease of explanation, are labeled A, B, C, D, and E. The network device transmits a low-power wake-up signal at the resource location indicated by C and transmits a preamble of the low-power wake-up signal at the resource locations indicated by A, B, D, and E.
[0214] It should be noted that, in FIG2G , if the network device does not wake up UE1, it may send the preamble of the low-power wake-up signal at all five first resource locations, but not send the wake-up information of the low-power wake-up signal.
[0215] In some embodiments, different preamble code positions correspond to different wake-up information positions of the low-power wake-up signal.
[0216] As shown in FIG2E , the preamble code and the wake-up information that can be sent at each low-power wake-up signal position are in one-to-one correspondence, that is, different preamble code positions correspond to different wake-up information positions of the low-power wake-up signal.
[0217] In some embodiments, each preamble position corresponds to a wake-up information position of multiple low-power wake-up signals.
[0218] For example, the resource locations configured by the network device for each group of terminal devices for sending preamble codes may be the same, and the resource locations configured by the network device for each group of terminal devices for sending wake-up information may be different.
[0219] Figure 2H is a schematic diagram of signal transmission according to an embodiment of the present disclosure. As shown in Figure 2H, a network device configures low-power wake-up signals for two groups of UEs, three groups of low-power wake-up signals for the first group of UEs, and two groups of low-power wake-up signals for the second group of UEs. Each group of positions includes a resource position P indicating a preamble for sending a low-power wake-up signal, and three resource positions Msg indicating wake-up information for sending the low-power wake-up signal. The three Msgs in each group of positions correspond to the same P. The first group of UEs includes three UEs, which can be represented by UE11, UE12, and UE13. The resource position indicated by Msg1 is the resource position configured by the network device for sending wake-up information for UE11, the resource position indicated by Msg2 is the resource position configured by the network device for sending wake-up information for UE12, and the resource position indicated by Msg3 is the resource position configured by the network device for sending wake-up information for UE13. The second group of UEs also includes three UEs, which can be represented by UE21, UE22, and UE23. The resource location indicated by Msg1 is the resource location configured by the network device for sending wake-up information for UE21, the resource location indicated by Msg2 is the resource location configured by the network device for sending wake-up information for UE22, and the resource location indicated by Msg3 is the resource location configured by the network device for sending wake-up information for UE23. The resource location indicated by P is the resource location configured by the network device for each group of UEs to send preambles, and P indicates different resource locations for different groups.
[0220] As shown in Figure 2H, for the convenience of explanation, the five first resource locations are recorded as A, B, C, D and E. The network device sends a preamble code of a low-power wake-up signal at the resource location indicated by P in B, sends a preamble code of a low-power wake-up signal at the resource location indicated by P in C, and sends wake-up information of a low-power wake-up signal at the resource location indicated by Msg3, indicating that the network device needs to wake up UE13 in the first group of UEs.
[0221] It should be noted that the location of sending the synchronization signal in Figure 2H is an exemplary description. If the network device does not need to wake up UE13 in the first group of UEs, it can send the preamble of the low-power wake-up signal at the resource location indicated by P in C, and not send the wake-up information of the low-power wake-up signal at the resource location indicated by Msg3 in C, and may not send the low-power wake-up signal at the resource location indicated by C. The network device can select the resource location indicated by P in any one or more groups of first resource locations within the resource period to send the synchronization signal.
[0222] In some embodiments, the network device may also send a low-power wake-up signal at a first group of resource locations. Figure 2I is a schematic diagram of a signal transmission according to an embodiment of the present disclosure. As shown in Figure 2I, referring to the above description of Figure 2H, the network device determines to wake up UE22 in the second group of UEs, and may send a preamble of a low-power wake-up signal at the resource location indicated by P in B, and send wake-up information of a low-power wake-up signal at the resource location indicated by Msg2. The network device also determines to wake up UE13 in the first group of UEs, and may send a preamble of a low-power wake-up signal at the resource location indicated by P in C, and send wake-up information of a low-power wake-up signal at the resource location indicated by Msg3.
[0223] In some embodiments, the network device can determine the third resource location based on the bitmap of the resource period, and send a synchronization signal at at least one fourth resource location. The fourth resource location may include a resource location in the third resource location except the fifth resource location. The fifth resource location may be a resource location configured by the network device for the first terminal device to be awakened; and a low-power wake-up signal is sent at the fifth resource location.
[0224] In some embodiments, the first resource location may include a resource location configured by the network device for each terminal device that is capable of sending a low-power wake-up signal.
[0225] FIG2J is a schematic diagram illustrating a signal transmission according to an embodiment of the present disclosure. As shown in FIG2J , the first resource location configured by the network device may include the first resource locations configured for UE1 and UE2. The resource location indicated by UE1 represents the resource location configured by the network device for UE1 to send a low-power wake-up signal, and the resource location indicated by UE2 represents the resource location configured by the network device for UE2 to send a low-power wake-up signal.
[0226] In some embodiments, the network device determines to wake up the first terminal device and sends a low-power wake-up signal at a sixth resource location, where the sixth resource location is a resource location configured by the network device for the first terminal device in the first resource location.
[0227] In some embodiments, the network device determines that it is not necessary to wake up any terminal device and may not send a low-power wake-up signal.
[0228] In some embodiments, the network device determines that it is not necessary to wake up any terminal device and may not send a synchronization signal.
[0229] In some embodiments, the network device determines that any terminal device needs to be woken up and can send a low-power wake-up signal at the first resource location corresponding to the terminal device.
[0230] As shown in FIG2J , the network device determines to wake up UE2 and sends a low-power wake-up signal at the first resource location corresponding to UE2, and determines to wake up UE1 and sends a low-power wake-up signal at the first resource location corresponding to UE1.
[0231] Step S2102: The terminal device performs signal synchronization according to the synchronization signal.
[0232] In some embodiments, the terminal device may receive a synchronization signal sent by the network device at at least one first resource location.
[0233] In some embodiments, the terminal device may receive a preamble of a low-power wake-up signal sent by a network device at at least one first resource location.
[0234] In some embodiments, the terminal device may receive a preamble code of a low-power wake-up signal sent by the network device at the first resource location where the network device sends the low-power wake-up signal.
[0235] In some embodiments, at the first resource location where the network device does not send a synchronization signal, the terminal device may not receive the synchronization signal.
[0236] In some embodiments, the terminal device can receive the synchronization signal sent by the network device at any first resource location.
[0237] As shown in Figure 2J, the network device is configured with five first resource locations. For the convenience of explanation, the five first resource locations are recorded as A, B, C, D, and E. The network device does not send a low-power wake-up signal at the resource location indicated by A. UE1 and UE2 may not receive a synchronization signal at the resource location indicated by A. The network device sends a low-power wake-up signal at the resource location indicated by B. UE1 and UE2 may receive a synchronization signal at the resource location indicated by B and perform signal synchronization based on the received synchronization signal. Afterwards, the network device sends a low-power wake-up signal at the resource location indicated by C. UE1 may receive the low-power wake-up signal at the resource location indicated by C and perform signal synchronization again based on the preamble in the low-power wake-up signal.
[0238] In this way, the preamble code of the low-power wake-up signal actually sent by the network device to the terminal device can be used as a synchronization signal, and the terminal device can perform signal synchronization based on the preamble code of the low-power wake-up signal sent by the network device at multiple first resource locations, thereby improving the synchronization accuracy.
[0239] In some embodiments, the terminal device may receive a synchronization signal at at least one fourth resource location and receive a low power consumption wake-up signal at a fifth resource location.
[0240] As shown in Figure 2E, the network device sends a preamble code of a low-power wake-up signal at a first resource location indicated by UE2. UE1 and UE2 can receive the preamble code of the low-power wake-up signal at the first resource location as a synchronization signal and perform signal synchronization based on the synchronization signal.
[0241] As shown in Figure 2F, the network device is configured with five first resource locations. For convenience of explanation, the five first resource locations are recorded as A, B, C, D, and E. The network device does not send a synchronization signal at the resource location indicated by A. UE1 and UE2 may not receive the synchronization signal at the resource location indicated by A. The network device sends a preamble of a low-power wake-up signal at the resource location indicated by B. UE1 and UE2 may receive the synchronization signal at the resource location indicated by B and perform signal synchronization based on the received synchronization signal. Afterwards, the network device sends a low-power wake-up signal at the resource location indicated by C. UE1 may receive the low-power wake-up signal at the resource location indicated by C and perform signal synchronization again based on the preamble in the low-power wake-up signal.
[0242] In this way, the network device can also send a preamble code of a low-power wake-up signal at the first resource location corresponding to the terminal device as a synchronization signal when not waking up the terminal device, so that the terminal device can receive synchronization signals at more resource locations to perform more signal synchronization, thereby improving the synchronization accuracy of the terminal device.
[0243] As shown in Figure 2G, the network device is configured with five first resource locations. For convenience of explanation, the five first resource locations are recorded as A, B, C, D, and E. The network device sends a synchronization signal at the resource location indicated by A. UE1 and UE2 can receive the synchronization signal at the resource location indicated by A and perform signal synchronization according to the synchronization signal. The network device also sends a synchronization signal at the resource location indicated by B. UE1 and UE2 can receive the synchronization signal at the resource location indicated by B and perform signal synchronization according to the synchronization signal. Afterwards, the network device sends a low-power wake-up signal at the resource location indicated by C. UE1 can receive the low-power wake-up signal at the resource location indicated by C and perform signal synchronization again according to the preamble in the low-power wake-up signal.
[0244] In this way, the terminal device can receive synchronization signals at more resource locations, thereby further improving the synchronization accuracy of the terminal device.
[0245] In some embodiments, the terminal device may receive a synchronization signal at at least one of the second resource location and the fourth resource location, and receive a low power consumption wake-up signal at the fifth resource location.
[0246] As shown in Figure 2B, the first resource locations configured by the network device within a resource cycle may include the first resource locations configured for UE1 and UE2, and the first resource locations for which no terminal device is configured. For ease of explanation, the first four first resource locations shown in Figure 2B are recorded as A, B, C, and D. UE1 receives synchronization signals at the resource locations indicated by A and B, and performs signal synchronization based on the received synchronization signals. Afterwards, UE1 receives a low-power wake-up signal at the resource location indicated by C, and performs signal synchronization again based on the preamble in the received low-power signal. That is, UE1 performs signal synchronization three times.
[0247] In this way, the terminal device can receive synchronization signals at both the resource location configured for the terminal device and the resource location not configured for the terminal device, thereby improving synchronization accuracy without causing additional signaling overhead.
[0248] As shown in FIG2C , the terminal device can receive the synchronization signal sent by the network device at the second resource location and perform synchronization according to the synchronization signal. In this way, the terminal device can receive the synchronization signal more flexibly.
[0249] It should be noted that step S2102 does not distinguish the correspondence between the preamble code and the wake-up information in the low-power wake-up signal. The preamble code received by the terminal device can be a common preamble code corresponding to a group of terminal devices, or a different preamble code corresponding to each wake-up information. It will not be repeated here.
[0250] The method involved in the embodiments of the present disclosure may include at least one of the above steps S2101 and S2102. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, and steps S2101+S2102 may be implemented as independent embodiments.
[0251] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2A .
[0252] By adopting the above method, the network device can send a synchronization signal at at least one resource location configured to send a synchronization signal, so that the terminal device can receive the synchronization signal at more resource locations, thereby improving the synchronization accuracy of the terminal device.

[0381] In some embodiments, the above method may include the method described in the embodiments of the above communication system, terminal equipment, network equipment, etc., which will not be repeated here.
[0382] In some embodiments, the first part (Preamble) and the second part (carrying wake-up information) of the low power wake-up signal (LP-WUS) may have a fixed timing relationship. For example, the Preamble and the second part may occupy consecutive OFDM symbols, or the interval between the Preamble and the second part may be predefined or configured. Based on this, the Preamble and the second part of each LP-WUS resource of the UE are one-to-one corresponding, that is, each UE has a dedicated Preamble. The LP-WUS of a UE may be periodically configured, and only one LP-WUS resource location may be configured in each period, or multiple LP-WUS resource locations may be configured in each period. The above-mentioned dedicated Preamble can be used as a synchronization signal.
[0383] In some embodiments, the timing relationship between the first part (Preamble) and the second part of the LP-WUS is configurable. Accordingly, multiple LP-WUS can be mapped to a common Preamble, and multiple LP-WUS have their own second parts. The second parts of the LP-WUS of different UEs can be mapped to a common Preamble. The LP-WUS of a UE can be periodically configured, and the resource locations (second parts) of multiple LP-WUS can be configured in each cycle. The second parts of multiple LP-WUS of a UE in a cycle can be associated with different first parts or with the same first part. The above-mentioned common Preamble can be used as a synchronization signal. Because each common Preamble corresponds to the LP-WUS of multiple UEs, the possibility of the network device actually transmitting the common Preamble increases, which increases the probability of sending the synchronization signal based on the Preamble, and is beneficial to improving the synchronization performance of the LP-WUS.
[0384] In some embodiments, the UE can achieve time-frequency synchronization by detecting the aforementioned preamble-based synchronization signal. Alternatively, the UE can achieve time-frequency synchronization by detecting a periodically configured synchronization signal and detecting the aforementioned preamble-based synchronization signal. With the latter method, the periodically configured synchronization signal remains unchanged, and the number of available synchronization signals increases, thereby improving the UE's synchronization accuracy. In addition, while maintaining the same synchronization accuracy, the periodically configured synchronization signal can be more sparse, thereby reducing resource overhead.
[0385] In some embodiments, the network device can configure the position of the Preamble used as a synchronization signal, but the network device does not necessarily send the synchronization signal at all configured positions. In this way, the synchronization signal sent by the network device can be non-periodic, and LP-WUR can detect the synchronization signal at each configured Preamble position.
[0386] In some embodiments, the method for configuring the Preamble position of the network device may include at least the following three methods:
[0387] Method 1: A UE detects the Preamble as a synchronization signal only at the LP-WUS position configured for it.
[0388] In some embodiments, if the LP-WUS of the UE is periodically configured, the synchronization signal of the UE is also periodically configured.
[0389] Method 2: The network device configures the position of the Preamble that may be used as the synchronization signal according to a certain period P. The above-configured position is a superset of the Preamble position of the LP-WUS of each UE in a group of UEs.
[0390] In some embodiments, each UE in a group of UEs can perform signal synchronization based on the synchronization signal with a period of P. This method ensures that the UE can detect the synchronization signal according to the period P, and ensures that all preambles of the LP_WUS of each UE can be used as synchronization signals. In particular, a UE may detect the preamble of the LP-WUS of another UE as a synchronization signal. This method can limit the period P1 of the LP-WUS of each UE in the group to be the same, that is, P1 = x*P, where x is a positive integer. Alternatively, the LP-WUS period of each UE in the group can be the same or different. Let the period of UE i be Pi = xi*P, where xi is a positive integer, and the xi of different UEs can be the same or different.
[0391] In some embodiments, each position used as a synchronization signal in the above-mentioned period P may be configured with the Preamble of the LP-WUS of at least one UE in the above-mentioned group of UEs. Alternatively, a position used as a synchronization signal in the above-mentioned period P may also be a position where the Preamble of the LP-WUS of any UE in the above-mentioned group of UEs is not configured. For a position used as a synchronization signal in the above-mentioned period P, if the Preamble of the LP-WUS of any UE in the above-mentioned group of UEs is not configured, then this position may not be used to transmit the Preamble used as a synchronization signal. Alternatively, for a position used as a synchronization signal in the above-mentioned period P, even if the Preamble of the LP-WUS of any UE in the above-mentioned group of UEs is not configured, the network device may still transmit the Preamble used as a synchronization signal at this position.
[0392] Method three, the position of the Preamble that can be used as a synchronization signal configured by the network device is the union of the LP-WUS Preamble positions of each UE in a group of UEs. Each UE in this group of UEs can perform signal synchronization based on the synchronization signal of the above union. Here, a bitmap can be used to configure the position of the Preamble that may be used as a synchronization signal. The positions of all Preambles that may be used as synchronization signals are obtained by periodically applying this bitmap. For example, in method two, for a position used as a synchronization signal in the above period P, if the LP-WUS Preamble of any UE in the above group of UEs is not configured, the above bitmap can indicate that this position is unavailable. Depending on the implementation of the network device, the above bitmap can also indicate that a Preamble position that is not configured with LP-WUS can be used as a synchronization signal.
[0393] In some embodiments, the method for a network device to send a synchronization signal may include at least the following three methods:
[0394] Method 1: For a location configured as a synchronization signal, the network device can send a synchronization signal at this location only if the network device sends an LP-WUS at this location.
[0395] For example, if a network device configures four LP-WUS resources for a UE, only the LP-WUS preamble actually sent to the UE can be used as a synchronization signal. This may cause the LP-WUS to be out of synchronization, forcing the LP-WUS to search for the preamble within a larger window or requiring the LP-WUS to continuously detect the preamble.
[0396] Figure 2J shows an example of using the LP-WUS preambles of multiple UEs as synchronization signals. As shown in Figure 2J , the network device configures three LP-WUS resources for UE1 and two LP-WUS resources for UE2. The union of these LP-WUS resources is still periodic. In Figure 2J , although only the LP-WUS preamble actually sent to a UE can be used as a synchronization signal, because the network device sends the LP-WUS for both UEs, the preambles of both LP-WUS can be used as synchronization signals. This helps improve the synchronization performance of the LP-WUS.
[0397] Figure 2I shows an example of using a common preamble as a synchronization signal. As shown in Figure 2I , the network device is configured with two groups of LP-WUSs, each group containing LP-WUSs for three UEs. Because each group contains three UEs, the network device is more likely to need to send a common preamble. In Figure 2I , although only the common preamble actually transmitting the LP-WUS can serve as a synchronization signal, because the network device sends two LP-WUSs, two common preambles are also sent. Both common preambles can serve as synchronization signals, thereby improving the synchronization performance of the LP-WUS.
[0398] Mode 2: The location used as the synchronization signal is configured with the LP-WUS Preamble of at least one UE in a group of UEs. The network device may only send the Preamble at this location, but not the second part of the LP-WUS.
[0399] By adopting this method, the network device can send synchronization signals at more locations, thereby improving the synchronization performance of LP-WUR.
[0400] Figure 2F shows an example of sending only the LP-WUS preamble as a synchronization signal. In Figure 2F , to enhance UE1's synchronization performance, the network device still sends UE2's LP-WUS preamble, even though it doesn't need to. This allows UE1 to synchronize signals based on both LP-WUS preambles. This improves LP-WUS synchronization performance.
[0401] In some embodiments, for each location configured for synchronization, if the location is configured with the LP-WUS preamble for at least one UE in a group of UEs, the network device may transmit the preamble. However, if the UE does not need to be woken up, the network device may not transmit the second part of the LP-WUS. This approach maximizes the number of locations where the base station transmits synchronization signals, thereby improving LP-WUS synchronization performance. Using this approach, synchronization signals can be transmitted periodically.
[0402] Figure 2G shows an example of sending preambles for all configured LP-WUSs as synchronization signals. In Figure 2G , although the network device only requires one LP-WUS for UE1, it sends preambles at all LP-WUS locations. UE1 can synchronize signals based on the preambles of the first three LP-WUSs and detect the LP-WUS at the third location. This improves LP-WUS synchronization performance.
[0403] Method 3: For a location used as a synchronization signal, regardless of whether the location is configured with the LP-WUS Preamble of at least one UE in a group of UEs, the network device may only send the Preamble at this location, but may not send the second part of the LP-WUS.
[0404] By adopting this method, network devices can send synchronization signals more flexibly, thereby improving the synchronization performance of LP-WUR.
[0405] Figure 2B is an example of sending a synchronization signal on a Preamble that is not configured with LP-WUS. As shown in Figure 2B, the network device configures two LP-WUS resources for UE1 and UE2 respectively. These four LP-WUS resources fail to cover all configured positions for synchronization signals. In Figure 2B, although the network device only needs one LP-WUS for UE1, the network device sends the Preamble at the previous LP-WUS position of UE2 and the first position where LP-WUS is not configured. Accordingly, UE1 can use the Preamble of the three LP-WUS as a synchronization signal, which is beneficial to improving the synchronization performance of LP-WUS. In particular, neither UE1 nor UE2 will attempt to receive the message part of the LP-WUS at the first position where LP-WUS is not configured, so no additional operations will be caused.
[0406] In some embodiments, for a location configured to be used as a synchronization signal, if the location is not configured with the Preamble of the LP-WUS of any UE in a group of UEs, the network device may send only the Preamble at this location, but the network device does not send the second part of the LP-WUS. For other locations configured as synchronization signals as described above, the network device sends the synchronization signal on the premise that the network device sends the LP-WUS of one UE in the above group of UEs at this location. Using this method, the network device can send synchronization signals more flexibly, thereby improving the synchronization performance of the LP-WUS. This method does not affect the detection of the LP-WUS of any UE in the above group of UEs. Specifically, when the UE detects the synchronization signal at the location where only the Preamble of the LP-WUS is sent, the UE does not need to try to detect the second part of the LP-WUS which does not exist.
[0407] As shown in Figure 2C, UE1 can use two preambles as synchronization signals to receive the LP-WUS, which helps improve the synchronization performance of the LP-WUS. In particular, neither UE1 nor UE2 attempts to receive the LP-WUS message part in the first position where the LP-WUS is not configured, so no additional operations are required.
[0408] Figure 2D shows an example of using a common preamble as a synchronization signal. As shown in Figure 2D , the network device is configured with two UE groups, each of which includes LP-WUS for three UEs. These two sets of common preambles fail to cover all configured locations for synchronization signals. In Figure 2D , the network device needs to send two LP-WUSs, and accordingly sends two common preambles. The network device can also send a preamble at the first location where no LP-WUS is configured. This increases the number of synchronization signals that can be measured, thereby improving the synchronization performance of the LP-WUS.
[0409] Using the above-mentioned methods 2 and 3, for locations where only the preamble is sent, the network device can send a preamble different from the location where the full LP-WUS is sent, thereby preventing the UE from blindly detecting the non-existent second part of the LP-WUS. However, the UE needs to detect two preambles, which increases the complexity of the UE. For method 3, for a location used as a synchronization signal in period P, if this location is not configured with an LP-WUS preamble for any UE in a group of UEs, the network device can also send the same preamble as the location where the full LP-WUS is sent, and no UE will attempt to detect the second part of the LP-WUS.
