[0071] As shown in FIG1 , a communication system 100 includes a user equipment 101 and a network device 102 .

[0072] In some embodiments, the user device 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0081] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method for a communication system 100, the method comprising:

[0082] In step S2101 , the network device 102 sends a wake-up signal.

[0083] In some embodiments, the network device 102 may send a wake-up signal to the user equipment 101. For example, the network device 102 sends the wake-up signal to different user equipments 101 in a broadcast manner.

[0084] In some embodiments, the wake-up signal includes first information and a first identifier corresponding to the device to be awakened, where the first information is used to indicate that the first identifier is at least one of a device identifier and a device group identifier.

[0085] The device to be awakened may be a user device to be awakened, or a user device in a device group to be awakened.

[0086] In some embodiments, the user equipment 101 may be in a Radio Resource Control (RRC) idle state or a connected state.

[0087] In some embodiments, the wake-up signal may be a low power consumption wake-up signal LP WUS, and the wake-up signal may be used to wake up the user equipment 101 .

[0088] In some embodiments, the UE ID may uniquely identify the user equipment 101. For example, the UE ID may be a temporary mobile station identifier (TSMI) or an index value configured by a network device. The TMSI of each user equipment 101 is defined by the protocol.

[0089] In some embodiments, the device group identifier may refer to a UE subgroup ID or a UE group ID. The device group identifier indicates the device group to which the user equipment 101 belongs, and the device group includes multiple user equipments 101.

[0090] In some embodiments, the first information may occupy one or more bits in the wake-up signal, and different bit values ​​corresponding to the first information may indicate different first identification types or categories.

[0091] In one example, when the bit value corresponding to the first information is the first value, the first identifier includes at least one device identifier.

[0092] In one example, when the bit value corresponding to the first information is the second value, the first identifier includes at least one device group identifier.

[0093] In one example, when the bit value corresponding to the first information is the third value, the first identifier includes at least one device identifier and at least one device group identifier.

[0094] The first value, the second value, and the third value are different. For example, if the first information occupies 2 bits, the first value may be 01, the second value may be 10, and the third value may be 11.

[0095] It is worth noting that when the network device needs to wake up a small number of user devices 101, if the first identifier carries a device group identifier, the user device 101 to be awakened and other user devices 101 in the same device group that do not need to be awakened may be awakened, thereby causing a false alarm for the user device 101 that does not need to be awakened.

[0096] In some embodiments, when the network device needs to wake up a smaller number of user devices 101, the first information is used to indicate that the first identifier may include at least one device identifier, that is, when at least one device identifier is carried in the first identifier, it is possible to wake up only the user device 101 corresponding to the at least one device identifier, avoiding waking up other user devices 101 that do not need to be woken up, thereby avoiding false alarms and ensuring the energy saving effect of the user devices 101 that do not need to be woken up.

[0097] It is worth noting that when the user equipment 101 needs to wake up a large number of user equipments 101, if the first identifier carries a large number of device identifiers, and the device identifiers occupy more bits, the wake-up signal payload may be too long.

[0098] In some embodiments, when user equipment 101 needs to wake up a large number of user equipment 101, the first information may indicate that the first identifier includes at least one device group identifier. For example, the first identifier may carry at least one device group identifier to wake up at least one device group. Alternatively, the first identifier may carry at least one user identifier and at least one device group identifier to wake up at least one user equipment 101 and user equipment 101 of at least one device group, thereby waking up a large number of user equipment 101. The bits occupied by the device group identifier may be fewer than the bits required by the device identifier. Therefore, the method of indicating the device group identifier in the first information can ensure demodulation performance and avoid the problem of an excessively long wake-up signal payload.

[0099] It is understandable that the device identifier may occupy 12 bits, 24 bits, or 48 bits. Taking the device identifier as TSMI as an example, TSMI may occupy 48 bits.

[0100] In some embodiments, the first identifier may occupy at least one bit in the wake-up signal, and the at least one bit corresponds one-to-one with at least one device group identifier.

[0101] In one example, the at least one bit includes a first bit, and the first bit corresponds to a first device group identifier. The first bit is used to indicate whether the corresponding first device group identifier is the device group identifier of the device group to be awakened. When the value of the first bit is 1, the first device group identifier is the device group identifier of the device group to be awakened; when the value of the first bit is 0, the first device group identifier is the device group identifier of the device group that does not need to be awakened.

[0102] The first bit may be applicable to any bit of the at least one bit.

[0103] Taking the device group identifier carried in the first identifier as an example for explanation, the plurality of bits may be in the form of a bitmap to indicate the device group identifier of the device group to be awakened.

[0104] For example, as shown in the example of Table 1, the first identifier occupies 4 bits, that is, the maximum value of N is 4. Each bit corresponds to a device group identifier, that is, each bit indicates whether a device group is to be awakened. Assuming that the bit value is 1, it indicates that the corresponding device group needs to be awakened. For example, when the value of the first bit is 1, it indicates that the device group corresponding to the first bit needs to be awakened. When the 4-bit value is 1001, it means that the first and fourth device groups will be awakened, and the second and third device groups do not need to be awakened; when the 4 bits are 0101, it means that the second and fourth device groups will be awakened, and the first and third device groups do not need to be awakened.

[0105] Table 1

[0106] In some embodiments, similar to the device identification, a corresponding device group identification may be configured for each device group, and the device group identification itself may be directly carried in the wake-up signal.

[0107] It's worth noting that semi-static configuration of the identifier type carried in the wake-up signal using higher-layer signaling is less flexible, as the wake-up signal can only carry the semi-statically configured identifier type. For example, if higher-layer signaling indicates that the wake-up signal carries the device identifier type, network device 102 must carry the device identifier in the wake-up signal it sends. If there are many device identifiers, the payload will be too long and scheduling may be inflexible, such as not being able to carry the device group identifier as required.

[0108] In some embodiments, the network device 102 synchronously indicates two pieces of information, namely the first identifier and the type of the first identifier, in the same wake-up signal. Therefore, the network device 102 can flexibly carry at least one of the device identifier and the device group identifier in the wake-up signal according to scheduling requirements, and promptly inform the user device 101, thereby improving the flexibility of the wake-up scheduling process.

[0109] In some possible implementations, the user equipment 101 receives a wake-up signal.

[0110] Step S2102 : The network device 102 sends first configuration information to the user equipment 101 .

[0111] In some embodiments, the first configuration information is used to determine a first number, where the first number is the number of all bits included in the wake-up signal.

[0112] In some embodiments, the network device 102 sends higher-layer signaling, such as Radio Resource Control (RRC) signaling, and the RRC signaling may include the first configuration information.

[0113] In some embodiments, when the types of the first identifier are different, such as a device identifier and / or a device group identifier, the total number of bits of the wake-up signal is the same, that is, always the first number.

[0114] In some embodiments, the first quantity may also be defined by a protocol.

[0115] In some embodiments, the user equipment 101 receives first configuration information sent by the network device 102 .

[0116] Step S2103 : The network device 102 sends second configuration information to the user equipment 101 .

[0117] In some embodiments, the second configuration information is used to determine the maximum number of device identifiers and / or device group identifiers carried in the first identifier.

[0118] In some embodiments, the network device 102 sends higher-layer signaling, such as RRC signaling, which may include the second configuration information.

[0119] In some embodiments, the network device 102 may send the first configuration information and the second configuration information in the same signaling or different signaling.

[0120] In some embodiments, when the types of the first identifiers are different, the maximum number of first identifiers that can be carried by the wake-up signal may be different.

[0121] In one example, when the first identifier carries at least one device identifier, the maximum number of device identifiers carried by the first identifier may be recorded as the second number K21.

[0122] In this example, the number of device identifiers actually indicated by the first identifier is less than or equal to the second number K21. The empty part can be filled with padding bits.

[0123] In another example, when the first identifier carries at least one device group identifier, the maximum number of device group identifiers carried by the first identifier may be recorded as the second number K22.

[0124] In this example, the number of device group identifiers actually indicated by the first identifier is less than or equal to the second number K22. The empty portion can be filled with padding bits.

[0125] In another example, when the first identifier carries at least one device group identifier and at least one device identifier, the maximum number of device identifiers carried by the first identifier can be recorded as the second number K23, and the maximum number of device group identifiers carried by the first identifier can be recorded as the second number K24.

[0126] In this example, the number of device identifiers actually indicated by the first identifier is less than or equal to the second number K23, and the empty part can be filled with padding bits. The number of device group identifiers actually indicated by the first identifier is less than or equal to the second number K24, and the empty part can be filled with padding bits.

[0127] Among them, K21 to K24 can be the same or different.

[0128] In some embodiments, the second configuration information may indicate the second numbers K21 to K24 in the above embodiments.

[0129] In some embodiments, the second number K21-K24 may also be determined based on the first number, such as being smaller than the first number, or determined based on a set ratio of the first number.

[0130] In some embodiments, the second number may also be protocol defined.

[0131] In some embodiments, to keep the first number unchanged, padding bits may be configured in the wake-up signal when the second numbers K21-K24 are different. When the type of the first identifier is different, the number of bits occupied by the first identifier is different, so the number of padding bits may also be different.

[0132] In an example, in the wake-up signal, the padding bit is configured as a preset value, for example, the preset value is 0.

[0133] To make it easier to understand, here are some specific examples:

[0134] Example 1:

[0135] The wake-up signal includes a first number of bits, for example, the first number is 50, that is, the wake-up signal has a total of 50 bits.

[0136] In the wake-up signal, the first information occupies a third number of bits, for example, the third number is 2, that is, the first information occupies 2 bits. When the value of the 2-bit bit is 01, the type corresponding to the first identifier is a device identifier; when the value of the 2-bit bit is 10, the type corresponding to the first identifier is a device group identifier; when the value of the 2-bit bit is 11, the type corresponding to the first identifier is a device identifier and a device group identifier.

[0137] In the wake-up signal, when the first identifier is at least one device identifier, taking one device identifier occupying 12 bits as an example, the number of bits occupied by the first identifier is less than or equal to 12*K21. For example, if the maximum number of device identifiers corresponding to the second number K21 is 4, the number of bits occupied by the first identifier is less than or equal to 48 bits.

[0138] In the wake-up signal, when the first identifier is at least one device group identifier, assuming that one device group identifier occupies one bit, the number of bits occupied by the first identifier is less than or equal to 1*K22. For example, if the maximum number of device group identifiers, i.e., the second number K22, is 16, the number of bits occupied by the first identifier is less than or equal to 16 bits.

[0139] In the wake-up signal, when the first identifier is at least one device identifier and at least one device group identifier, with one device identifier occupying 12 bits and one device group identifier occupying 1 bit, the number of bits occupied by the first identifier is less than or equal to: (12*K23+1*K24). For example, if the maximum number of device identifiers, i.e., the second number K23, is 2, and the maximum number of device group identifiers, i.e., K24, is 16, then the number of bits occupied by the first identifier is less than or equal to 40 bits.

[0140] Example 2:

[0141] Still using the example in Example 1, for example, the wake-up signal has a total of 50 bits, and the first information occupies 2 bits.

[0142] When the first identifier is at least one device identifier, assuming that the bits occupied by the first identifier are equal to 24 bits, the number of padding bits is (50-2-24)=24, that is, the 24 bits are all padding bits, for example, the padding bits are all 0.

[0143] When the first identifier is at least one device group identifier, assuming that the first identifier occupies 16 bits, the number of padding bits is (50-2-16)=32, that is, the 32 bits are all padding bits, for example, all padding bits are 0.

[0144] When the first identifier is at least one device identifier and at least one device group identifier, assuming that the first identifier occupies 40 bits, the number of padding bits is (50-2-40)=8, that is, the 8 bits are all padding bits, for example, all padding bits are 0.

[0145] According to the above two examples, it can be known that when the type of the first identifier is different, the number of padding bits is different, but the first number is always the same.

[0146] In some embodiments, after knowing the type of the first identifier, the user equipment 101 can know the portion of the filling bits in the wake-up signal and the portion of the bits occupied by the first identifier according to the type, so that the user equipment can correctly demodulate the first identifiers of different types.

[0147] In some embodiments, the user equipment 101 receives second configuration information sent by the network device 102 .

[0148] In some embodiments, when there are many user devices that need to be awakened, such as when the number of device identifiers that the first identifier needs to carry is greater than the maximum number of device identifiers, the device group identifier can be carried in the first identifier, or the device group identifier and the device identifier can be carried in the first identifier to ensure that the user devices that need to be awakened are awakened without increasing the effective load and minimize false alarms.

[0149] Step S2104 : When the wake-up signal includes the first identifier of the user equipment 101 , the user equipment 101 switches from the sleep state to the working state.

[0150] In some embodiments, the first identifier is a device identifier and / or a device group identifier of the user device 101 .

[0151] In some embodiments, the user equipment 101 wakes up, that is, the main transceiver of the user equipment 101 switches from a sleep state to an active state.

[0152] In some embodiments, the user equipment 101 may include a primary transceiver and a low power consumption receiver. When the primary transceiver is in a sleep state, the user equipment 101 uses the low power consumption receiver to monitor the LP WUS.

[0153] Upon receiving the corresponding LP WUS, which indicates wakeup, the main transceiver of the user equipment 101 switches from the sleep state to the active state. The main transceiver can effectively save energy in the sleep state and can perform data transmission, reception, and processing in the active state.

[0154] In some embodiments, the user equipment 101 can obtain the type of the first identifier carried by the wake-up signal based on the first information, and thus can obtain the device identifier and / or device group identifier of the device to be awakened based on the type of the first identifier and the bits occupied by the first identifier.

[0155] Step S2105: When the first identifier includes the device identifier, the user equipment 101 initiates a random access procedure after switching from the sleep state to the working state.

[0156] In some embodiments, the user equipment 101 is in an RRC idle state.

[0157] In some embodiments, the user equipment 101 switches from the sleep state to the working state without performing a paging process.

[0158] In some embodiments, when the user device 101 is awakened by the device identifier, it indicates that the user device 101 is the user device 101 that the network device 102 needs to wake up, and it is not a false alarm. Therefore, after the user device 101 switches from the sleep state to the working state, it can directly initiate a random access process without paging.

[0159] In some embodiments, for the user equipment 101 awakened by the device group identifier, the user equipment 101 needs to first perform a paging process after switching from the sleep state to the working state.

[0160] It is worth noting that the above interaction method is applicable to all user equipment 101 that receive the wake-up signal.

[0161] In some embodiments, steps S2102, S2103, and S2105 are optional.

[0162] In some embodiments, the method may include steps S2101 and S2104.

[0163] In some embodiments, the method may include steps S2101 , S2102 , and S2104 .

[0164] In some embodiments, the method may include steps S2101 , S2103 , and S2104 .

[0165] In some embodiments, the method may include steps S2101 , S2102 , S2103 , and S2105 .

[0166] In some embodiments, the method may include steps S2101 , S2102 , S2103 , and S2104 .

[0167] In some embodiments, the order of steps S2101, S2102, and S2103 is not limited and can be interchanged. For example, step S2102 or S2103 can be performed first, and then step S2101.

[0168] In the disclosed embodiment, network device 102 transmits a wake-up signal to user device 101, and simultaneously indicates to user device 101, in the same wake-up signal, the first identifier of the device to be awakened and the type of the first identifier carried by the wake-up signal. User device 101 thus correctly demodulates the first identifier based on the type of the first identifier and determines whether it needs to be awakened. In this embodiment, network device 102 can determine whether to awaken a single user device 101 or a group of devices based on the circumstances of each scheduling, and adaptively adjust the first identifier carried by the wake-up signal, making scheduling more flexible.

[0187] FIG3b is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG3b, the embodiment of the present disclosure relates to a communication method for a network device 102. The method includes:

[0188] In step S3201, the network device 102 sends a wake-up signal.

[0189] Among them, the implementation of step S3201 can refer to the relevant implementation of step S2101, and will not be repeated here.

[0190] In some embodiments, the network device 102 sends a wake-up signal to the user device 101 .

[0191] In some embodiments, the wake-up signal includes first information and a first identifier of the user equipment to be woken up.

[0192] In some embodiments, the first information is used to indicate that the first identifier is at least one of a device identifier and a device group identifier.

[0193] In some embodiments, the device identifier is one of the following: a temporary mobile station identifier TSMI; an index value configured by the network device.

[0194] In some embodiments, when the bit value corresponding to the first information is a first value, the first identifier includes at least one device identifier.

[0195] When the bit value corresponding to the first information is the second value, the first identifier includes at least one device group identifier.

[0196] When the bit value corresponding to the first information is the third value, the first identifier includes at least one device identifier and at least one device group identifier.

[0197] In some embodiments, when the first identifier includes a device group identifier, the wake-up signal includes at least one bit for indicating the first identifier. The at least one bit corresponds one-to-one with the at least one device group identifier, and the at least one bit includes a first bit for indicating whether the corresponding first device group identifier is the device group identifier of the device group to be awakened.

[0198] For example, in a scenario where the first bit corresponds to the first device group identifier, when the value of the first bit is 1, the first device group identifier is the device group identifier of the device group to be awakened; when the value of the first bit is 0, the first device group identifier is the device group identifier of the device group that does not need to be awakened.

[0199] It can be understood that the first bit and the first device group identifier are only used for description. In at least one bit, any bit corresponds to a respective device group identifier, and the application method can also refer to the description of the first bit.

[0200] In some embodiments, when the first identifier includes at least one device identifier and / or at least one device group identifier, the number of all bits included in the wake-up signal is the same first number.

[0201] In one example, the first number may be configured by the network device 102 or defined by a protocol.

[0213] Optionally, the second configuration information is used to determine the maximum number of device identifiers and / or device group identifiers carried in the first identifier.

[0214] In some embodiments, the wake-up signal may include some padding bits.

[0215] In some embodiments, the number of padding bits in the wake-up signal is determined according to the first number or the second number, where the second number is the maximum number of device identifiers and / or device group identifiers carried in the first identifier.

[0216] Among them, the padding bits can be used to keep the total number of bits of the wake-up signal unchanged, so that when the first identifier type is different, the user equipment 101 can know the positions of the bits used to indicate the first identifier and the padding bits in the wake-up signal, so as to facilitate the correct demodulation of the first identifier in the wake-up signal.

[0217] In the embodiment of the present disclosure, the network device 102 sends a wake-up signal to the user device 101, and simultaneously indicates to the user device 101 the first identifier of the device to be awakened and the type of the first identifier carried by the wake-up signal.

[0291] In some embodiments, when the user equipment 101 is awakened by the device group identifier, the user equipment 101 needs to first perform a paging process after switching from a sleep state to a working state.

[0292] In the embodiment of the present disclosure, when the user equipment 101 is awakened by the device identifier in the awakening signal, the paging process can be omitted and random access can be directly initiated, thereby reducing communication delay and improving communication efficiency.

[0293] To facilitate understanding of the embodiments of the present disclosure, some specific examples are listed below:

[0294] Example 1:

[0295] The network device 102 carries UE identification type indication information in the wake-up signal, where the UE identification type indication information is used to indicate that the UE identification type carried by the wake-up signal is: UE ID, UE subgroup ID, or UE ID+UE subgroup ID.

[0296] In some embodiments, the UE identification type indication information corresponds to the first information in the aforementioned embodiment.

[0297] In some embodiments, the UE ID corresponds to the device identification in the aforementioned embodiments.

[0298] In some embodiments, the UE subgroup ID corresponds to the device group identifier in the aforementioned embodiments.

[0299] Example 2:

[0300] When the UE identity type indication information indicates that the UE identity type carried by the wake-up signal is UE ID, the wake-up signal carries the ID of the UE to be awakened.

[0301] Example 3:

[0302] The number of UE IDs can be one or more. The number N of UE IDs is configured by higher-layer signaling. When the actual number of UEs to be awakened is less than N, the remaining bits can be filled with a preset value. The UE ID can be a TSMI or an index configured by the base station.

[0303] In some embodiments, the spare bits correspond to the padding bits in the aforementioned embodiments.

[0304] Example 4:

[0305] When the UE identity type indication information indicates that the UE identity type carried by the wake-up signal is UE subgroup ID, the wake-up signal indicates the UE subgroup ID to be awakened.

[0306] The UE subgroup to be awakened may be one or more.

[0307] The wake-up signal indicates the UE subgroup ID to be woken up and can be in the form of a bitmap, for example, there are 4 subgroups in total, corresponding to 4 bits. When the 4 bits are 1001, it means that the 1st / 4th subgroup will be woken up, and the 2nd / 3rd subgroup does not need to be woken up.

[0308] Example 5:

[0309] When the UE identity type indication information indicates that the UE identity type carried by the wake-up signal is UE ID+UE subgroup ID, the wake-up signal indicates at least one UE ID to be awakened and a UE subgroup ID to be awakened.

[0310] Example 6:

[0311] When the wake-up signal indicates that it carries different types of UE identifiers, the total number of bits of the wake-up signal is the same.

[0312] Example 7:

[0313] The total number of bits of the wake-up signal can be configured by higher-layer signaling.

[0314] Example 8:

[0315] For a UE to be awakened and indicated with a UE ID, the UE will not perform a paging monitoring process after waking up, but will directly initiate a random access process.
