Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a subgroup information transmission device and communication system. Background Technology

[0002] To reduce the power consumption of terminal devices, low-power wake-up signal (LPWUS) technology has been proposed. For scenarios where multiple subgroups are woken up, related technologies propose using LPWUS information to indicate the code point values ​​of one or more subgroups, supporting the monitoring of one or more monitoring occasions (MOs) within the same beam during the LPWUS occasion (LO).

[0003] When multiple MOs exist under the same beam, the terminal device cannot predict which subgroup the network device will wake up, nor can it predict how many subgroups need to be woken up. Therefore, the terminal device may need to detect all MOs under the same beam in sequence, resulting in a large energy consumption of the terminal device. Summary of the Invention

[0004] This application provides a subgroup information transmission device and communication system to solve the problem of high energy consumption when terminal equipment sequentially detects multiple MOs of the same beam.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a subgroup information transmission method. This method can be applied to a network device. The method may include: transmitting LPWUS information in at least one MO via a first beam. Wherein, the LPWUS information transmitted in each MO is used to indicate the code point value of a subgroup in a woken-up subgroup, and the indication information of the first MO in the at least one MO is used to indicate at least one of the following: the first MO is the last MO in the at least one MO under the first beam; the number of code point values ​​transmitted through the at least one MO.

[0007] In this scheme, when a network device transmits LPWUS information on at least one of X MOs, the network device can indicate at least one of the following through the first MO among these at least X MOs: the first MO is the last MO among the at least X MOs in the first beam, and the number of code point values ​​transmitted through the at least X MOs. When the terminal device detects the MOs of the first beam, it can determine whether to detect the subsequent MOs of the first beam based on the indication information of the received first MO and the decoding result of the LPWUS information. For example, when the first MO is the last MO among the at least X MOs, the terminal device can stop detecting the subsequent MOs. In this way, the detection time of the terminal device can be reduced, and the power consumption of the terminal device can be saved.

[0008] In one possible implementation, within a single LO, the first beam corresponds to X MOs, and at least one MO is one of the first Y MOs out of the X MOs. Here, X is a positive integer, and Y is an integer greater than or equal to 0. It can be understood that setting X to a positive integer allows the network device to transmit LPWUS information for one or more wake-up subgroups on one or more MOs of a beam. Furthermore, by transmitting LPWUS information on the first Y MOs, the terminal device can detect the LPWUS information as quickly as possible, saving power consumption.

[0009] In one possible implementation, the code point values ​​transmitted in the first Y MOs are arranged in ascending order.

[0010] In one possible implementation, transmitting LPWUS information in at least one MO via a first beam includes: transmitting LPWUS information in the first Y MOs of X MOs via the first beam, based on the number of awakened subgroups. As an example, the LPWUS information transmitted in each MO may include a preamble, code point values, and CRC scrambling information.

[0011] In one possible implementation, X is predefined or determined based on the network configuration.

[0012] In one possible implementation, Y is equal to the number of awakened subgroups, and the indication information of the first MO is specifically used to indicate the number of non-repeating code point values ​​sent through the first Y MOs; or, Y is greater than the number of awakened subgroups, and the indication information of the first MO is specifically used to indicate the number of repeating code point values ​​and non-repeating code point values ​​sent through the first Y MOs.

[0013] In one possible implementation, the indication information for the first MO is a termination character placed after the LPWUS information of the first MO. This termination character indicates that the first MO is the last MO among at least one MO in the first beam. It can be understood that when the first MO is the last MO among those used to transmit LPWUS information in the first beam, setting a termination character in the first MO informs the terminal device that the current MO is the last MO among those used to transmit LPWUS information in the first beam. The network device will not transmit LPWUS information in subsequent MOs of the first beam, thus allowing the terminal device to stop detecting subsequent MOs of the first beam, thereby reducing the power consumption of the terminal device.

[0014] In one possible implementation, the first MO is the first MO of at least one MO, and the indication information of the first MO is carried in the LPWUS information of the first MO. The indication information of the first MO is used to indicate the number of code point values ​​transmitted through at least one MO. For example, an information field of N1 bits is added to the LPWUS information of the first MO. The value of this information field can be used to indicate the number of code point values ​​transmitted through at least one MO. It can be understood that by adding N1 bits to the LPWUS information of the first MO to indicate the number of code points transmitted, the terminal device can determine the number of code points to be received based on these N1 bits, and only detect the first Y MOs corresponding to these code points, instead of detecting X MOs sequentially, thereby reducing the power consumption of the terminal device and shortening the detection time.

[0015] In one possible implementation, the indication information of the first MO is specifically used to indicate the number of total code point values ​​transmitted through at least one MO. The total code point values ​​may include non-repeating code point values, or they may include both repeating and non-repeating code point values.

[0016] In one possible implementation, an information field is set in each of at least one MO, and the information field of each MO is used to indicate: the code point value of the next MO is a repeated code point value, or the code point value of the next MO is a non-repeated code point value, or no further code point values ​​will be transmitted.

[0017] In one possible implementation, the indication information of the first MO is co-encoded with or independently encoded with the code point value indicated by the LPWUS information of the first MO.

[0018] In one possible implementation, the first MO is the first MO among at least one MOs. The indication information of the first MO is its time-domain offset, which indicates the number of code point values ​​transmitted through at least one MO. The time-domain offset is the time deviation between the start time of the first MO and a preset reference point. The preset reference point is predefined or determined according to network configuration. It can be understood that by configuring different time-domain offsets, the network device can indicate the number of transmitted code point values ​​by controlling the time-domain offset. This allows the network device to detect MOs based on different time-domain offsets and obtain the actual number of transmitted code points, aiding subsequent detection. Since at most the first Y MOs are detected, instead of sequentially detecting X MOs, the power consumption of the terminal device is reduced, and the detection time is shortened.

[0019] In one possible implementation, different numbers of awakened subgroups correspond to different time-domain offsets; transmitting LPWUS information in at least one MO via a first beam includes: determining the time-domain offset based on the number of awakened subgroups; and transmitting LPWUS information in at least one MO via the first beam, starting at the time of the time-domain offset from a preset reference point.

[0020] In one possible implementation, the first MO is the first MO of at least one MO. The indication information of the first MO is the preamble sequence or the overlapping sequence of the LPWUS information of the first MO. The preamble sequence or the overlapping sequence of the LPWUS information of the first MO is used to indicate the number of code point values ​​transmitted through at least one MO. Different preamble sequences or different overlapping sequences of preamble sequences are used to indicate different numbers of code point values. It can be understood that the network device can use the sequence information of the LPWUS preamble and / or the overlaid sequence information of the preamble sequence to carry the number of code points to be transmitted, so that the terminal device can determine the number of code points to be received based on the sequence information of the preamble and / or the overlaid sequence information of the preamble sequence. Since the terminal device only needs to detect the first Y MOs at most, instead of detecting X MOs sequentially, the power consumption of the terminal device is reduced, and the detection time is shortened.

[0021] In one possible implementation, different preamble sequences are used to indicate different numbers of code point values; or, different preamble sequence sequence classes are used to indicate different numbers of code point values; or, different preamble sequence overlapping sequences are used to indicate different numbers of code point values; or, different preamble sequence overlapping sequences are used to indicate different numbers of code point values.

[0022] In one possible implementation, the preamble sequence or the overlapping sequence of the preamble sequence of the LPWUS information of each MO in at least one MO is used to indicate the number of code point values ​​transmitted through at least one MO.

[0023] In one possible implementation, the indication information of the first MO is a preamble sequence or an overlapping sequence of preamble sequences of the LPWUS information of the first MO. The preamble sequence or overlapping sequence of preamble sequences of the LPWUS information of the first MO is a first sequence, which is used to indicate that the first MO is the last MO among at least one MO in the first beam. It can be understood that when the first MO is the last MO among the MOs used to transmit LPWUS information in the first beam, the preamble sequence information and / or the overlaid sequence information of the preamble sequence of the first MO can be used to indicate to the terminal device that the first MO is the last MO among at least one MO in the first beam. The network device will not transmit LPWUS information in subsequent MOs of the first beam, thus allowing the terminal device to stop detecting subsequent MOs of the first beam, thereby reducing the power consumption of the terminal device.

[0024] In one possible implementation, the first MO is the first MO of at least one MO. The indication information of the first MO is carried in the scrambling information of the LPWUS information of the first MO. The indication information of the first MO indicates the number of code point values ​​transmitted through at least one MO. The scrambling information of the LPWUS information includes at least one of the following: scrambling information of LPWUS data, and scrambling information of LPWUS Cyclic Redundancy Check (CRC). It can be understood that the network device can use the LPWUS scrambling information to carry the number of transmitted code points, enabling the terminal device to determine the number of code points to be received based on the descrambling result of the LPWUS scrambling information. Since the terminal device only needs to detect the first Y MOs at most, instead of sequentially detecting X MOs, the power consumption of the terminal device is reduced, and the detection time is shortened.

[0025] In one possible implementation, the scrambling information of the LPWUS information of each MO in at least one MO carries the indication information of the first MO.

[0026] In one possible implementation, the first MO is the first MO of at least one MO, and the indication information of the first MO is an overlapping sequence of LPWUS information of the first MO. This overlapping sequence of LPWUS information of the first MO indicates the number of code point values ​​transmitted through at least one MO, and different overlapping sequences indicate different numbers of code point values. It can be understood that the network device can use the LPWUS overlaid sequence to carry the number of transmitted code points, allowing the terminal device to determine the number of code points to be received based on the LPWUS overlaid sequence. Since the terminal device only needs to detect the first Y MOs at most, instead of sequentially detecting X MOs, the power consumption of the terminal device is reduced, and the detection time is shortened.

[0027] In one possible implementation, the overlapping sequence of LPWUS information of each MO in at least one MO is used to indicate the number of code point values ​​transmitted through at least one MO.

[0028] Secondly, this application provides a subgroup information transmission method. This method can be applied to network devices. The method may include: transmitting a first LPSS sequence via a first beam, the first LPSS sequence indicating the number of code point values ​​to be transmitted via the first beam in at least one MO, with different LPSS sequences indicating different numbers of code point values; transmitting LPWUS information via the first beam in at least one MO, the LPWUS information transmitted in each MO indicating the code point value of a subgroup within a woken-up subgroup. The different LPSS sequences may include any of the following: different LPSS sequences, or different offset values ​​of the LPSS sequences.

[0029] In this scheme, network devices can use the LPSS sequence to carry the number of code points to be transmitted, allowing terminal devices to determine the number of code points to be received based on the LPSS sequence. Since the terminal device only needs to detect the first Y MOs at most, instead of detecting the X MOs sequentially, the power consumption of the terminal device is reduced and the detection time is shortened.

[0030] Thirdly, this application provides a subgroup information transmission method. This method can be applied to network devices. The method may include: transmitting first LPWUS information via a first beam in a first MO, the first LPWUS information indicating the code point value of a first subgroup in a woken-up subgroup, and the first MO corresponding to a preset MO of the first subgroup; transmitting second LPWUS information via the first beam in a second MO, the second LPWUS information indicating the code point value of a second subgroup in a woken-up subgroup, and the second MO corresponding to a preset MO of the second subgroup. Wherein, the first subgroup and the second subgroup are different subgroups, and different subgroups correspond to different preset MOs.

[0031] For example, assuming the first beam corresponds to X MOs within a LO, the MOs used to transmit the first and second subgroups are determined in any of the following ways: Method 1: When X equals 2, the index value of the first subgroup is odd, and the index value of the second subgroup is even. Subgroups with odd indices are detected in the first MO (e.g., the first MO), and subgroups with even indices are detected in the second MO (e.g., the second MO). Method 2: When X equals 2, the index value of the first subgroup is less than or equal to a first value, and the index value of the second subgroup is greater than the first value, where the first value is the median of the total number of all subgroups. The first half of the subgroups are detected in the first MO (e.g., the first MO), and the second half are detected in the second MO (e.g., the second MO). Method 3: When X is an integer greater than or equal to 2, the position of the first MO among the X MOs is determined by the remainder of the index value of the first subgroup and X, and the position of the second MO among the X MOs is determined by the remainder of the index value of the second subgroup and X. For example, the subgroup with index value 1 is detected in MO1, and the subgroup with index value 8 is detected in MO2.

[0032] In this scheme, by pre-fixing the correspondence with MOs, network devices can only send LPWUS information at fixed locations. Accordingly, terminal devices only need to detect fixed locations, instead of blindly detecting X MOs, thereby reducing the power consumption of terminal devices.

[0033] Fourthly, this application provides a subgroup information transmission method. This method can be applied to network devices. The method may include: transmitting LPWUS information in at least one MO via a first beam. The LPWUS information transmitted in each MO is used to indicate the code point value of a subgroup within a woken-up subgroup; the first beam corresponds to X MOs within a LO, and the at least one MO is the first Y MOs among the X MOs, with the code point values ​​transmitted in the first Y MOs arranged in ascending order; X is a positive integer, and Y is an integer greater than or equal to 0.

[0034] In this scheme, the network device can send code point values ​​in ascending order in the first Y MOs corresponding to the first beam. This allows the terminal device to determine whether to detect subsequent MOs based on the relationship between the detected code point value and the code point value of the subgroup to which the terminal device belongs. For example, if the code point value of the subgroup to which the terminal device belongs is less than the detected code point value, the detection of subsequent MOs can be stopped without blind detection, thereby reducing the power consumption of the terminal device.

[0035] Fifthly, this application provides a subgroup information transmission method. This method can be applied to a terminal device. The method may include: detecting a MO (Motion Object) of a first beam; detecting first LPWUS information at a first MO of the first beam, the first LPWUS information indicating the code point value of a subgroup in a woken-up subgroup; determining, based on the indication information of the first MO, whether to detect subsequent MOs of the first beam, the indication information of the first MO including the decoding result of the first LPWUS information. Wherein, the indication information of the first MO indicates at least one of the following: the first MO is the last MO among at least one MO that transmits LPWUS information under the first beam; the number of code point values ​​transmitted through at least one MO.

[0036] In this scheme, when the terminal device detects the MO of the first beam, it can determine whether to detect subsequent MOs of the first beam based on the received indication information of the first MO and the decoding result of the LPWUS information. For example, when the first MO is the last MO among at least one MO, the terminal device can stop detecting subsequent MOs. This reduces the detection time of the terminal device and saves power consumption.

[0037] In one possible implementation, within a single LO, the first beam corresponds to X MOs, and the first MO is one of the first Y MOs out of the X MOs. Here, X is a positive integer, and Y is an integer greater than or equal to 0.

[0038] In one possible implementation, the code point values ​​detected in the first Y MOs are arranged in ascending order.

[0039] In one possible implementation, X is predefined or determined based on the network configuration.

[0040] In one possible implementation, Y is equal to the number of awakened subgroups, and the indication information of the first MO is specifically used to indicate the number of non-repeating code point values ​​sent through the first Y MOs; or, Y is greater than the number of awakened subgroups, and the indication information of the first MO is specifically used to indicate the number of repeating code point values ​​and non-repeating code point values ​​sent through the first Y MOs.

[0041] In one possible implementation, the indication information of the first MO is a termination symbol placed after the first LPWUS information; based on the indication information of the first MO, determining whether to detect subsequent MOs of the first beam includes: decoding the first LPWUS information; if a termination symbol is detected after the first LPWUS information, determining that subsequent MOs of the first beam will not be detected, the termination symbol being used to indicate that the first MO is the last MO among at least one MO that transmits LPWUS information through the first beam.

[0042] In one possible implementation, the first MO is the first of at least one MO that transmits LPWUS information through the first beam; determining whether to detect subsequent MOs of the first beam based on the indication information of the first MO includes: decoding the first LPWUS information to obtain code point values ​​of a subgroup and indication information, the indication information being used to indicate the number of code point values ​​transmitted through at least one MO; and determining whether to detect subsequent MOs of the first beam based on the code point values ​​of the subgroup and the number of code point values ​​transmitted through at least one MO.

[0043] In one possible implementation, each of at least one MO is provided with an information field, which indicates whether the code point value of the next MO is a repeated code point value, or the code point value of the next MO is a non-repeating code point value, or no further code point values ​​will be transmitted. After determining whether to detect subsequent MOs of the first beam, the method may further include: decoding the information field of each MO; and determining whether to detect subsequent MOs of the first beam based on the decoding result of the information field of the current MO, the decoding result of the LPWUS information of the current MO, and the number of code point values ​​transmitted through at least one MO.

[0044] In one possible implementation, the first MO is the first of at least one MO transmitting LPWUS information through the first beam. Detecting the MOs of the first beam includes: detecting the first MO based on different time-domain offsets, where the time-domain offset is the time deviation between the start time of the first MO and a preset reference point, and different time-domain offsets are used to indicate the number of different code point values. Detecting the first LPWUS information in the first MO of the first beam includes: detecting the first LPWUS information at a time at a first time-domain offset from the preset reference point. Based on the indication information of the first MO, determining whether to detect subsequent MOs of the first beam includes: determining whether to detect subsequent MOs of the first beam based on the number of code point values ​​indicated by the first time-domain offset and the decoding result of the first LPWUS information.

[0045] In one possible implementation, the first MO is the first of at least one MO that transmits LPWUS information through the first beam; determining whether to detect subsequent MOs of the first beam based on the indication information of the first MO includes: decoding the first LPWUS information to obtain code point values ​​and indication information of a subgroup, wherein the indication information is a preamble sequence of the first LPWUS information or an overlapping sequence of preamble sequences, and the preamble sequence of the first LPWUS information or the overlapping sequence of preamble sequences is used to indicate the number of code point values ​​transmitted through at least one MO; and determining whether to detect subsequent MOs of the first beam based on the code point values ​​of the subgroup and the number of code point values ​​transmitted through at least one MO.

[0046] In one possible implementation, the first MO is the last MO among at least one MO transmitting LPWUS information through the first beam. Determining whether to detect subsequent MOs of the first beam based on the indication information of the first MO includes: decoding the first LPWUS information to obtain code point values ​​and indication information for a subgroup, wherein the indication information is a preamble sequence or an overlapping sequence of preamble sequences of the first LPWUS information, and the preamble sequence or the overlapping sequence of preamble sequences of the first LPWUS information is a first sequence used to indicate that the first MO is the last MO among at least one MO under the first beam; and determining whether to detect subsequent MOs of the first beam based on the code point values ​​of the subgroup and the number of code point values ​​transmitted through at least one MO.

[0047] In one possible implementation, the first MO is the first of at least one MO that transmits LPWUS information through the first beam. Determining whether to detect subsequent MOs of the first beam based on the indication information of the first MO includes: decoding the first LPWUS information to obtain code point values ​​and indication information for a subgroup, wherein the indication information is scrambling information of the LPWUS information, the scrambling information indicating the number of code point values ​​transmitted through at least one MO, and the scrambling information of the LPWUS information including at least one of the following: scrambling information of LPWUS data, cyclic redundancy check (CRC) scrambling information of LPWUS; and determining whether to detect subsequent MOs of the first beam based on the code point values ​​of the subgroup and the number of code point values ​​transmitted through at least one MO.

[0048] In one possible implementation, the first MO is the first of at least one MO that transmits LPWUS information through the first beam; determining whether to detect subsequent MOs of the first beam based on the indication information of the first MO includes: decoding the first LPWUS information to obtain the code point values ​​and indication information of a subgroup, wherein the indication information is an overlap sequence of the first LPWUS information, the overlap sequence of the first LPWUS information is used to indicate the number of code point values ​​transmitted through at least one MO, and the scrambling information of the LPWUS information includes at least one of the following: scrambling information of LPWUS data, cyclic redundancy check (CRC) scrambling information of LPWUS; and determining whether to detect subsequent MOs of the first beam based on the code point values ​​of a subgroup and the number of code point values ​​transmitted through at least one MO.

[0049] Sixthly, this application provides a subgroup information transmission method. This method can be applied to a terminal device. The method may include: receiving a first LPSS sequence via a first beam, the first LPSS sequence indicating the number of code point values ​​to be transmitted via the first beam at at least one MO, with different LPSS sequences indicating different numbers of code point values; detecting at least one MO of the first beam to obtain LPWUS information, the LPWUS information detected in each MO indicating the code point value of a subgroup in the woken-up subgroup.

[0050] In this scheme, network devices can use the LPSS sequence to carry the number of code points to be transmitted, allowing terminal devices to determine the number of code points to be received based on the LPSS sequence. Since the terminal device only needs to detect the first Y MOs at most, instead of detecting the X MOs sequentially, the power consumption of the terminal device is reduced and the detection time is shortened.

[0051] Seventhly, this application provides a subgroup information transmission method. This method can be applied to a terminal device. The method may include: detecting the MO of a first beam; detecting first LPWUS information in the first MO of the first beam, the first LPWUS information indicating the code point value of the first subgroup in the woken subgroup, and the first MO corresponding to a preset MO of the first subgroup; and determining whether to detect subsequent MOs of the first MO based on the decoding result of the first LPWUS information.

[0052] For example, the terminal device can detect MO in any of the following ways: Method 1: When X is 2, detect the first half of the subgroup in the first MO and the second half of the subgroup in the second MO; Method 2: When X is 2, detect the subgroup with odd index value in the first MO and the subgroup with even index value in the second MO; Method 3: Determine the position of the subgroup in the first MO in the X MOs based on the subgroup ID mod X.

[0053] In this scheme, by pre-fixing the correspondence between MOs, the terminal device only needs to detect fixed positions (such as the first MO). When the terminal device detects the first MO of the first beam, it can determine whether to detect subsequent MOs of the first beam based on the received indication information of the first MO and the decoding result of the LPWUS information. For example, when the first MO is the last MO among at least one MO, the terminal device can stop detecting subsequent MOs. In this way, the detection time of the terminal device can be reduced, and the power consumption of the terminal device can be saved.

[0054] Eighthly, this application provides a subgroup information transmission method. This method can be applied to a terminal device. The method may include: detecting the MO of a first beam; detecting first LPWUS information in the first MO of the first beam, the first LPWUS information indicating the code point value of a subgroup in the woken-up subgroup; if the detected code point value is greater than the code point value of the subgroup to which the terminal device belongs, terminating the detection of subsequent MOs of the first beam; if the detected code point value is equal to the code point value of the subgroup to which the terminal device belongs, waking up and establishing a service; if the detected code point value is less than the code point value of the subgroup to which the terminal device belongs, continuing the detection of subsequent MOs of the first beam.

[0055] In this scheme, the network device can send code point values ​​in ascending order in the first Y MOs corresponding to the first beam. This allows the terminal device to determine whether to detect subsequent MOs based on the relationship between the detected code point value and the code point value of the subgroup to which the terminal device belongs. For example, if the code point value of the subgroup to which the terminal device belongs is less than the detected code point value, the detection of subsequent MOs can be stopped without blind detection, thereby reducing the power consumption of the terminal device.

[0056] Ninthly, this application provides a communication device, which may include a processor, a communication interface, and a memory coupled to the processor and the communication interface. The memory stores instructions, and when the processor executes the instructions, it causes the communication device to perform the method described in any one of the first to eighth aspects.

Those skilled in the art will understand that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0096] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0097] The Internet of Things (IoT) refers to connecting all objects to the internet through terminal devices, thereby enabling intelligent identification and management. The IoT primarily provides two types of services: the first is saving data received by terminal devices into a database and analyzing the collected data; the second is sending instructions and information to terminal devices.

[0098] For example, Figure 1 A schematic diagram of the architecture of an Internet of Things (IoT) system is shown.

[0099] like Figure 1 As shown, an Internet of Things (IoT) system can include: a sensing layer, a network layer, and an application layer.

[0100] The perception layer consists of various terminal devices and sensors with functions such as sensing, identification, control, and execution, such as mobile phones, personal computers (PCs), wearable devices, smart home devices, intelligent transportation terminals, wireless terminals in industrial control, wireless terminals in smart grids, wireless terminals in smart cities, and wireless terminals in remote medical surgery.

[0101] The network layer, also known as the transport layer, is the nervous system of the Internet of Things (IoT), primarily responsible for information transmission. The network layer includes the access layer, aggregation layer, and switching layer. The access layer is equivalent to the physical layer and data link layer of a computer network. Radio frequency identification (RFID) tags, sensors, and access layer devices constitute the basic units of the IoT sensing network. Access layer network technologies are divided into wireless access and wired access. Wireless access includes wireless LANs and M2M communication in mobile communications; wired access includes fieldbus, power line access, television cable, and telephone lines. The aggregation layer, located between the access layer and the switching layer, performs data packet aggregation, forwarding, and switching, as well as local routing, filtering, and traffic balancing. Aggregation layer technologies are also divided into wireless and wired networks. Wireless networks include wireless LANs, wireless metropolitan area networks, mobile M2M communication, and dedicated wireless communications; wired networks include LANs and fieldbus. The switching layer provides high-speed, secure data transmission with quality of service (QoS) guarantees for the IoT and can be IP networks, virtual private networks (VPNs), the Internet, or mobile communication networks.

[0102] The application layer serves as the interface between the Internet of Things (IoT) and users (including people, organizations, and other systems). It is divided into a service layer and an industry application layer. The service layer uses middleware software to achieve physical isolation and seamless connectivity between sensing hardware and application software, providing efficient aggregation and storage of massive amounts of data. Through data mining and intelligent data processing, it offers secure network management and intelligent services to the industry application layer. The industry application layer provides IoT services to various industries such as smart healthcare, smart transportation, smart homes, and smart logistics. It primarily consists of application layer protocols, with different protocols required for different industries.

[0103] In such Figure 1 Based on the IoT system shown, this application provides a communication system 10.

For example, a next-generation Node B (gNB), TRP, TP in a new radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system. Alternatively, network device 11 may also be a network node constituting a gNB or transmission point. For example, a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). CUs and DUs can be separate entities or included within the same network element. Alternatively, network device 11 can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, in V2X technology, the network device can be a roadside unit (RSU).

[0109] It should be noted that network device 11 may be the device or apparatus shown above, or it may be a component (e.g., a chip), module, or unit in the device or apparatus shown above. This application does not limit it.

Specifically, terminal equipment 12 includes devices that provide voice connectivity to a user, devices that provide data connectivity to a user, or devices that provide both voice and data connectivity to a user. For example, it may include a handheld device with wireless connectivity or a processing device connected to a wireless modem. Terminal equipment 12 can communicate with the core network via a radio access network (RAN), exchanging voice or data with the RAN, or interacting with the RAN to exchange voice and data.

[0111] It should be noted that the terminal device 12 may be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, module or control unit in the device or apparatus shown above. This application does not limit the specific device or apparatus.

[0112] Since Rel-16, the 3rd Generation Partnership Project (3GPP) has been researching energy-saving technologies for 5G terminal devices. While existing energy-saving technologies for terminal devices can significantly reduce the power consumption of 5G terminal devices, there is still a considerable gap between them and the power consumption requirements of IoT terminals, such as the standby time requirements of industrial sensor terminals for more than one year and wearable terminals for more than two weeks.

[0113] In response, the low-power wake-up signal (LPWUS) technology was proposed.

[0114] For example, Figure 3 A schematic diagram of a low-power wake-up mechanism is shown. (For example...) Figure 3 As shown, the terminal device may include a main communication unit and a wake-up receiver unit. When there is no service demand, the terminal device disables the main communication unit and only enables the wake-up receiver unit. When the network device needs to communicate with the terminal device, the network device can send LPWUS to the terminal device. The terminal device's wake-up receiver unit detects the LPWUS; upon successful reception, it triggers the main communication unit to open, establishing a communication connection with the network device. Service transmission and reception are then completed through this established connection. It can be understood that by introducing LPWUS onto the traditional communication unit, low latency can be maintained while reducing power consumption.

[0115] When transmitting a signal, the transmitting end (such as a network device) first encodes the digital signal to be transmitted (i.e., the original information bits) to obtain encoded information bits. Then, it uses on-off keying (OOK) modulation to modulate the encoded information bits onto an orthogonal frequency division multiplexing (OFDM) waveform, obtaining an OOK-modulated carrier signal. Finally, the carrier signal is transmitted. At the receiving end (such as a terminal device), after receiving the carrier signal, it can demodulate and decode the carrier signal to recover the digital signal.

[0116] The following section details the OOK modulation scheme. The OOK modulation schemes mainly include OOK-1 and OOK-4.

[0117] For example, Figure 4This is a schematic diagram of OFDM symbol modulation using the OOK-1 modulation method.

[0118] Figure 4 This describes an OFDM symbol after OOK-1 modulation from a frequency domain perspective. An OFDM symbol contains only one bit. First, the transmitting device modulates the subcarriers based on the information bits to be transmitted. For passive IoT (Ambient IoT), when the subcarrier is 1 (OOK = 1), it means all subcarriers have been modulated. When the subcarrier is 0 (OOK = 0), all subcarriers have zero power consumption. A modulated OFDM symbol is obtained by performing an inverse fast fourier transform (IFFT) and adding a cyclic prefix (CP).

[0119] For example, Figure 5 This is a schematic diagram of OFDM symbol modulation using the OOK-4 modulation method.

[0120] Figure 5 This diagram describes an OFDM symbol modulated with OOK-4 in the time domain, transforming the OOK by M bits. The number of chips in the diagram is M=4, meaning one OFDM symbol contains four bits, or four chips. After signal generation, the transmitting device can modify the signal or not. Further, the transmitting device generates N subcarrier information in the frequency domain using a discrete Fourier transform (DFT) or a least squares transform. The M-bit OOK also generates N' samples. If the transmitting device does not truncate or perform other additional modifications to the signal, then N'=N.

[0121] In both of the above methods, to ensure a flat signal spectrum during transmission, an overlaid sequence is introduced to modulate the signal, generating the final transmitted signal. Typically, there are two methods: the first is to multiply the overlaid sequence with the original information bits or its sampled signal in the time domain; the second is to modulate the overlaid sequence onto OFDM subcarriers for transmission in the frequency domain. For example, Figure 6 Schematic diagrams of four overlaid sequences are shown. Regardless of the method used, overlaid sequences can be used to modulate LPWUS, resulting in a flat spectral distribution during LPWUS transmission.

[0122] Typically, network devices group terminal devices that share the same paging time into a subgroup.

[0123] For example, Figure 7 A schematic diagram of a subgroup is shown. For example... Figure 7 As shown, the network device can be divided into multiple subgroups, each consisting of multiple terminal devices sharing the same paging occasion (PO). The network device sends the same LPWUS message to all users within the same subgroup to wake up all users in the same subgroup, thereby improving wake-up efficiency.

[0124] It should be noted that the aforementioned subgroups may also be referred to as groups, categories, or other possible names, and this application does not impose any limitations on this. A subgroup may include one or more users, or it may not include any users. In addition, the methods of dividing subgroups may include, but are not limited to: grouping terminal devices that share the same paging time into one subgroup, dividing subgroups based on the user's location, and of course, dividing subgroups based on other methods, which this application does not impose any limitations on.

[0125] Currently, network devices can wake up subgroups in the following two ways.

[0126] The first method is the bitmap method. Let's take a scenario where the data is divided into 8 subgroups as an example. Figure 8 As shown, one bit represents one subgroup. When a subgroup's bit is 0, it means the subgroup should not be woken up; when a subgroup's bit is 1, it means the subgroup should be woken up. For example, 00100100 means waking up the 2nd and 5th subgroups. In this method, since each subgroup corresponds to one bit, the network device can simultaneously indicate whether each of the 8 subgroups needs to be woken up. However, regardless of whether a group of users needs to be woken up, the network device must indicate this using 8 bits together, resulting in significant overhead.

[0127] The second method is the codepoint method. Let's take the example of dividing the data into 8 subgroups. For example... Figure 9 As shown, a code point value consists of 3 bits. Specifically, code point 000 represents the first subgroup, code point 001 represents the second subgroup, code point 010 represents the third subgroup, code point 011 represents the fourth subgroup, code point 100 represents the fifth subgroup, code point 101 represents the sixth subgroup, code point 110 represents the seventh subgroup, and code point 111 represents the eighth subgroup. In this method, the network device only needs 3 bits to wake up one subgroup at a time, thus saving overhead compared to the bitmap method. However, this method can only wake up one subgroup at a time.

[0128] In general, for radio resource control (RRC) in an idle or inactive state, only one subgroup is woken up each time. In this case, using code points is more advantageous. However, under high load, network devices may need to wake up multiple subgroups, meaning multiple subgroups are woken up.

[0129] For scenarios where there are multiple wake-up subgroups, the relevant technology proposes to use LPWUS to indicate the code point value of one or more subgroups in a portion of the paging timing, supporting the monitoring of one or more monitoring occasions (MO) in the same beam within the low-power wake-up signal occasion (LPWUS occasion, LO).

[0130] For example, Figure 10 A schematic diagram is shown of scanning multiple intra-beam MOs of a single LO.

[0131] like Figure 10 As shown in (a), in the idle or inactive state, within one LO (Local Opening) cycle, the network device has identified at least one subgroup to be woken up, but cannot determine which beam's coverage area the user is within. Therefore, the network device can sequentially scan each beam, i.e., send LPWUS information to activate the woken-up subgroup on each beam. Each of the N beams corresponds to X MOs. The network device can first send LPWUS on at least one MO among the X MOs on beam 1, then send LPWUS on at least one MO among the X MOs on beam 2, and so on, finally sending LPWUS on at least one MO among the X MOs on beam N. Figure 10 As shown in (b), since the network device already knows which beam the terminal device is in the coverage area of ​​in the connected state, the network device does not need to scan each beam sequentially, but directly sends LPWUS on at least one MO of the beam corresponding to the terminal device (e.g., beam 1).

[0132] Since there are multiple MOs under the same beam, the terminal device cannot predict which subgroup the network device will wake up, nor can it predict how many subgroups need to be woken up. Therefore, the terminal device may need to detect these MOs sequentially according to the X value, resulting in a large energy consumption of the terminal device.

[0133] For example, Figure 11 This diagram illustrates the transmission of code points within multiple MOs of a single beam. Assume that a terminal device belonging to the 8th subgroup with code point value 111 is located within the coverage area of ​​beam 1. For example... Figure 11As shown, beam 1 corresponds to X pre-defined MOs. The network device can sequentially send code point values ​​010 and 100 to MO1 and MO2 respectively. Since the terminal device cannot predict which subgroup the network device will wake up, nor how many subgroups need to be woken up, the terminal device may need to sequentially detect these MOs based on the X values. For example, if the terminal device detects code point value 010 in MO1, it determines that the 8th subgroup has not been indicated and continues detecting MO2; then, if the terminal device detects code point value 100 in MO2, it determines that the 8th subgroup has still not been indicated and continues detecting MO3; then, if the terminal device does not detect a code point value in MO3, it determines that the 8th subgroup has not been indicated and continues detecting MO4; ...; if the terminal device does not detect a code point value in MOX, it determines that the 8th subgroup has not been indicated. It is understandable that only after the terminal device completes the detection of X MOs can it determine whether activation is needed, resulting in significant energy consumption for the terminal device.

[0134] In view of the above problems, embodiments of this application provide a subgroup information transmission method. In this method, when a network device transmits LPWUS information of a woken-up subgroup at least in at least one of X MOs, the network device can indicate at least one of the following through the first MO: the first MO is the last MO in the at least one MO under a first beam, and the number of code point values ​​transmitted through the at least one MO. When detecting the MOs of the first beam, the terminal device can determine whether to detect subsequent MOs of the first beam based on the received indication information of the first MO and the decoding result of the LPWUS information. For example, when the first MO is the last MO in the at least one MO, the terminal device can stop detecting subsequent MOs. This reduces the detection time of the terminal device and saves power consumption.

[0135] It should be noted that the subgroup information transmission method provided in this application embodiment can be applied to scenarios where subgroups are woken up in an idle or inactive state, as well as scenarios where subgroups are woken up in a connected state. When this method is applied to scenarios where subgroups are woken up in an idle or inactive state, for paging services, the concept of "wake-up subgroup" can be reused. It is understood that this method is not limited to paging services and can also be applied to other services, which can be determined according to actual usage requirements, and this application embodiment does not impose any limitations.

[0136] The subgroup information transmission method provided in this application embodiment can be applied to, for example, Figure 2The communication system 11 shown, or other possible communication systems, are not limited to this embodiment. The communication system may include at least one network device and at least one terminal device connected to the network device. Uplink (UL) data and downlink (DL) data can be transmitted between the network device and the terminal device.

[0137] In practical implementation, network devices or terminal devices may have the following capabilities: Figure 12 The components shown.

[0138] For example, Figure 12 This is a schematic diagram of the hardware structure of a communication device provided in an embodiment of this application. Figure 12 As shown, the communication device 1200 includes at least one processor 1201, a communication line 1202, and at least one communication interface 1203. Further, the communication device 1200 may also include a memory 1204. The processor 1201, memory 1204, and communication interface 1203 are connected via the communication line 1202.

[0139] Processor 1201 may be a central processing unit (CPU), a network processor (NP), or a combination of a CPU and an NP. Processor 1201 may further include a hardware chip. The hardware chip may be an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a combination thereof. The PLD may be a complex programmable logic device (CPLD), a field-programmable gate array (FPGA), a generic array logic (GAL), or any combination thereof. The processor may also be any other device with processing capabilities, such as a circuit, device, or software module.

[0140] The communication line 1202 may include a path for transmitting information between components included in the communication device.

[0141] The communication interface 1203 can be used to communicate with other devices or communication networks (such as the Internet of Things, satellite communication, Ethernet, radio access network (RAN), and wireless local area networks (WLAN)). The communication interface 1203 can be a module, circuit, transceiver, or any device capable of enabling communication.

[0142] The memory 1204 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and / or instructions; it may also be a random access memory (RAM) or other type of dynamic storage device capable of storing information and / or instructions; it may also be an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.), a magnetic disk storage medium or other magnetic storage device; or any other medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer.

[0143] In one possible design, the memory 1204 can exist independently of the processor 1201, meaning the memory 1204 can be an external memory of the processor 1201. In this case, the memory 1204 can be connected to the processor 1201 via communication line 1202 to store instructions or program code. When the processor 1201 calls and executes the instructions or program code stored in the memory 1204, it can realize the subgroup information transmission provided in the following embodiments of this application. In another possible design, the memory 1204 can also be integrated with the processor 1201, meaning the memory 1204 can be an internal memory of the processor 1201. For example, the memory 1204 can be a cache, which can be used to temporarily store some data and / or instruction information, etc.

[0144] As one possible implementation, processor 1201 may include one or more CPUs, for example Figure 12 CPU0 and CPU1 in the example. Alternatively, the communication device 1200 may include multiple processors, such as... Figure 12The processors 1201 and 1207 are included. Alternatively, the communication device 1200 may also include an output device 1205 and an input device 1206. For example, the input device 1206 may be a keyboard, mouse, microphone, or joystick, and the output device 1205 may be a display screen or speaker.

[0145] It should be noted that the communication device 1200 can be a general-purpose device or a special-purpose device. For example, the communication device 1200 can be a base station, mobile phone, desktop computer, laptop computer, network server, tablet computer, embedded device, chip system, or something similar. Figure 12 Devices with similar structures. This application does not limit the type of communication device 1200 to any particular embodiment.

[0146] The subgroup information transmission method provided in the embodiments of this application is described below. Each device mentioned in the following method embodiments can have... Figure 12 The components shown will not be described again.

[0147] Figure 13 This is a flowchart illustrating a subgroup information transmission method provided in an embodiment of this application.

[0148] like Figure 13 As shown, the method may include the following steps S101 to S104.

[0149] S101. The network device transmits LPWUS information in at least one MO via the first beam.

[0150] Based on the description of the above embodiments, the subgroup information transmission method provided in this application can be applied to scenarios where subgroups are woken up in an idle or inactive state, or to scenarios where subgroups are woken up in a connected state.

[0151] When this method is applied to a scenario where a subgroup is woken up in an idle or inactive state, the first beam mentioned above is any one of the beams covered by the network device. The network device can scan on each beam in sequence, that is, send LPWUS information for activating the woken-up subgroup on each beam according to the subgroup information transmission method provided in the embodiments of this application.

[0152] When this method is applied to a scenario where a subgroup is woken up in a connected state, the first beam is the beam corresponding to the UE coverage area, and the network device can send LPWUS information in at least one MO using only the first beam.

[0153] In some embodiments, for any beam within a LO, each beam corresponds to X MOs, and each of the X MOs can be used to transmit LPWUS information.

[0154] In some embodiments, X is predefined or determined based on network configuration. X is a positive integer, thereby allowing network devices to transmit LPWUS information to one or more wake-up subgroups on one or more MOs of a beam.

[0155] In some embodiments, Y is an integer greater than or equal to 0. Y is greater than or equal to the number of awakened subgroups. For example, when Y = 0, the number of awakened subgroups is 0; when Y = 1, the number of awakened subgroups is 1. Each subgroup in the awakened subgroups corresponds to a code point value, and different subgroups correspond to different code point values. That is, the network device can send LPWUS information in the first Y MOs of X MOs through the first beam according to the number of awakened subgroups.

[0156] In some embodiments, the at least one MO is the first Y MOs out of X MOs, where Y is an integer less than or equal to X. For example... Figure 14 As shown, when Y subgroups need to be activated, the terminal device can send LPWUS information of the Y subgroups through beam 1 on MO1, MO2, ..., MOY.

[0157] In some embodiments, the LPWUS information transmitted in each MO can be used to indicate the code point value of a subgroup within the woken-up subgroup. As an example, the LPWUS information transmitted in each MO may include a preamble, the code point value, and cyclic redundancy check (CRC) scrambling information. The preamble is used to synchronize the transmission signals between the transmitter and receiver, the code point value is used to indicate the woken-up subgroup, and the CRC scrambling information is used for error correction verification of the preamble.

[0158] In some embodiments, the code point values ​​transmitted in the first Y MOs of X MOs are arranged in a preset order. This preset order can be predefined or configured by the network device. The preset order can be from smallest to largest or from largest to smallest.

[0159] Taking a system divided into 8 subgroups as an example, where code point value 000 represents the 1st subgroup, code point value 001 represents the 2nd subgroup, code point value 010 represents the 3rd subgroup, code point value 011 represents the 4th subgroup, code point value 100 represents the 5th subgroup, code point value 101 represents the 6th subgroup, code point value 110 represents the 7th subgroup, and code point value 111 represents the 8th subgroup. If the preset rule or network configuration rule is that the code point values ​​are arranged in ascending order, then the transmission priority of these 8 code point values ​​from high to low is as follows: 000, 001, 010, 011, 100, 101, 110, 111. Accordingly, the terminal device can determine the detection strategy based on preset rules or network configuration rules: if the code point value detected by the terminal device is greater than the code point value of the subgroup to which the terminal device belongs, then the terminal device terminates the detection of subsequent MOs of the first beam; if the code point value detected by the terminal device is equal to the code point value of the subgroup to which the terminal device belongs, then the terminal device wakes up and establishes the service; if the code point value detected by the terminal device is less than the code point value of the subgroup to which the terminal device belongs, then the terminal device can continue to detect subsequent MOs of the first beam.

[0160] For example, Figure 15 This diagram illustrates the transmission of code point values ​​in descending order. (Example:) Figure 15 As shown, if the woken-up subgroups are the 1st, 4th, and 7th subgroups, the network device can send the code point value of the 1st subgroup (000) in MO1, the code point value of the 4th subgroup (011) in MO2, and the code point value of the 7th subgroup (110) in MO3, in ascending order of code point value. If the code point value of the subgroup to which the terminal device belongs is 000, and 000 is detected in MO1, then the terminal device is woken up and service is established. If the code point value of the subgroup to which the terminal device belongs is greater than 000, then the terminal device continues detection in MO2.

[0161] Furthermore, if the code point value of the subgroup to which the terminal device belongs is 001 or 010, and code point value 011 is detected in MO2, then the terminal device stops detecting MO3. If the code point value of the subgroup to which the terminal device belongs is 011, and code point value 011 is detected in MO2, then the terminal device wakes up and establishes the service. If the code point value of the subgroup to which the terminal device belongs is greater than 011, then the terminal device continues to detect MO3.

[0162] Furthermore, if the code point value of the subgroup to which the terminal device belongs is 100 or 101, and code point value 110 is detected in MO3, then the terminal device stops detecting MO4. If the code point value of the subgroup to which the terminal device belongs is 110, and code point value 110 is detected in MO3, then the terminal device wakes up and establishes the service. If the code point value of the subgroup to which the terminal device belongs is 111, and the terminal device does not know the number of MOs used to send LPWUS information, then the terminal device continues to detect MO4. If the code point value of the subgroup to which the terminal device belongs is 111, and the terminal device knows the number of MOs used to send LPWUS information (e.g., 3), then the terminal device stops detecting MO4.

[0163] In some embodiments, the indication information of the first MO in at least one MO is used to indicate at least one of the following:

[0164] (1) The first MO is the last MO among at least one MO in the first beam.

[0165] When the first MO is the last MO among the MOs used to transmit LPWUS information in the first beam, the indication information of the first MO can be used to inform the terminal device that the current MO is the last MO among the MOs used to transmit LPWUS information in the first beam. The network device will not transmit LPWUS information in the subsequent MOs of the first beam. In this way, the terminal device can stop detecting the subsequent MOs of the first beam, thereby reducing the power consumption of the terminal device.

[0166] For the specific implementation of (1), please refer to the description of Embodiment 1 below, which will not be repeated here.

[0167] (2) The number of code point values ​​transmitted through at least one MO. Wherein, the first MO is any one or more MOs among at least one MO. For example, the first MO is the first MO or all of the MOs among at least one MO.

[0168] By indicating the number of code point values ​​transmitted through at least one MO in the first MO, the terminal device can infer whether previous code point values ​​were indicated or whether subsequent MOs were used to transmit code point values ​​based on the code point values ​​already detected by the current MO, and then determine whether to detect subsequent MOs of the first beam.

[0169] For the specific implementation of (2), please refer to the description of Embodiments 2 to 7 below, which will not be repeated here.

[0170] As an example, in the case where Y equals the number of awakened subgroups, the indication information of the first MO can specifically be used to indicate the number of non-repeating code point values ​​sent through the first Y MOs.

[0171] That is, the Y code point values ​​transmitted through the first Y MOs are all different.

[0172] For example, Figure 16 This diagram illustrates the non-repeating code point values ​​transmitted via the first Y MOs. (See diagram for example.) Figure 16 As shown, when a network device wakes up the terminal devices in the 1st, 4th, and 7th subgroups, it can send the code point value 000 for the 1st subgroup in MO1, the code point value 011 for the 4th subgroup in MO2, and the code point value 110 for the 7th subgroup in MO3. The code point values ​​sent by these three MOs are different.

[0173] As another example, for the case where Y is greater than the number of awakened subgroups, the indication information of the first MO is specifically used to indicate the number of repeating code point values ​​and non-repeating code point values ​​sent through the first Y MOs.

[0174] That is, the Y code point values ​​transmitted through Y MOs are partially the same.

[0175] For example, Figure 17 This diagram illustrates the repeating and non-repeating code point values ​​transmitted via the first Y MOs. (Example) Figure 17 As shown, when the network device wakes up the terminal devices in the 1st, 4th, and 7th subgroups, it can send the code point value 000 of the 1st subgroup in MO1 and MO2 respectively, send the code point value 011 of the 4th subgroup in MO3 and MO4 respectively, and send the code point value 110 of the 7th subgroup in MO5 and MO6 respectively. The code point values ​​sent by these 6 MOs are partially the same.

[0176] S102. The terminal equipment detects the MO of the first beam.

[0177] S103, The terminal device detects the first LPWUS information in the first MO of the first beam. The first LPWUS information is used to indicate the code point value of a subgroup in the woken-up subgroup.

[0178] S104. The terminal device determines whether to detect subsequent MOs of the first beam based on the indication information of the first MO. The indication information of the first MO includes the decoding result of the first LPWUS information.

[0179] For example, the terminal device detects LPWUS information starting from the first MO of the first beam. When the first LPWUS information is detected in the first MO of the first beam, the first LPWUS information can be decoded to obtain the decoding result, which may include at least the code point value of a woke-up subgroup. Then, based on the indication information of the first MO, the terminal device can determine whether to detect subsequent MOs of the first beam.

[0180] In some embodiments, the indication information of the first MO can be at least one of the following:

[0181] ① The indication information of the first MO is a termination symbol placed after the LPWUS information of the first MO. This termination symbol is used to indicate that the first MO is the last MO among at least one MO under the first beam.

[0182] ② The first MO is the first MO of at least one MO. The indication information of the first MO is carried in the LPWUS information of the first MO. The indication information of the first MO is used to indicate the number of code point values ​​transmitted through at least one MO.

[0183] ③ The first MO is the first MO of at least one MO. The indication information of the first MO is the time domain offset of the first MO. The time domain offset is used to indicate the number of code point values ​​transmitted through at least one MO. The time domain offset is the time deviation between the start time of the first MO and the preset reference point.

[0184] ④ The first MO is the first MO of at least one MO. The indication information of the first MO is the preamble sequence of the LPWUS information of the first MO or the overlaid sequence of the preamble sequence. The preamble sequence of the LPWUS information of the first MO or the overlaid sequence of the preamble sequence is used to indicate the number of code point values ​​transmitted through at least one MO. Different preamble sequences or different overlaid sequences of preamble sequences are used to indicate different numbers of code point values.

[0185] ⑤ The indication information of the first MO is the preamble sequence of the LPWUS information of the first MO or the overlaid sequence of the preamble sequence. The preamble sequence of the LPWUS information of the first MO or the overlaid sequence of the preamble sequence is the first sequence. The first sequence is used to indicate that the first MO is the last MO among at least one MO under the first beam.

[0186] ⑥ The first MO is the first MO of at least one MO. The indication information of the first MO is carried in the scrambling information of the LPWUS information of the first MO. The indication information of the first MO is used to indicate the number of code point values ​​transmitted through at least one MO. The scrambling information of the LPWUS information includes at least one of the following: scrambling information of LPWUS data, and CRC scrambling information of LPWUS.

[0187] ⑦ The first MO is the first MO of at least one MO. The indication information of the first MO is the overlaid sequence of the LPWUS information of the first MO. The overlaid sequence of the LPWUS information of the first MO is used to indicate the number of code point values ​​transmitted through at least one MO. Different overlaid sequences are used to indicate different numbers of code point values.

[0188] For the specific implementation methods of the above 7 types of indication information, please refer to the descriptions of Examples 1 to 7 below.

[0189] In the subgroup information transmission method provided in this application embodiment, when the network device transmits LPWUS information in at least one of X MOs, the network device can indicate at least one of the following through the first MO among these at least one MO: the first MO is the last MO among the at least one MOs in the first beam, and the number of code point values ​​transmitted through the at least one MO. When detecting the MOs of the first beam, the terminal device can determine whether to detect the subsequent MOs of the first beam based on the received indication information of the first MO and the decoding result of the LPWUS information. For example, when the first MO is the last MO among the at least one MOs, the terminal device can stop detecting the subsequent MOs. In this way, the detection time of the terminal device can be reduced, and the power consumption of the terminal device can be saved.

[0190] For ease of understanding, the following describes, in conjunction with several embodiments, the specific implementation methods of the network device sending LPWUS information and the terminal device receiving LPWUS information in the process of implementing the subgroup information transmission method provided in the embodiments of this application.

[0191] Example 1: Introduce a termination symbol at the last MO in at least one MO.

[0192] In this embodiment, the first MO is the last MO among at least one MO, and the indication information of the first MO is a termination symbol placed in the first MO, which is used to indicate that the first MO is the last MO among at least one MO under the first beam.

[0193] In some embodiments, the interaction process between network devices and terminal devices is as follows:

[0194] Step 1: The network device sends LPWUS information in the first Y MOs of X MOs through the first beam according to the number of woken subgroups, and places a termination character after the LPWUS information of the last MO in the first Y MOs.

[0195] In some embodiments, the LPWUS information sent in the first Y MOs indicates the code point value of the woken subgroup, and the network device can send the code point value in the first Y MOs in ascending order, and place a terminating terminator after the LPWUS information of the last MO in the first Y MOs.

[0196] Step 2: The terminal equipment detects the MO of the first beam.

[0197] Step 3: The terminal device detects the first LPWUS information in the first MO of the first beam and decodes the first LPWUS information. The first LPWUS information is used to indicate the code point value of a subgroup in the woken subgroup.

[0198] In some embodiments, the first LPWUS information may include a preamble, code point value, and CRC scrambling information.

[0199] Step 4: If the terminal device detects a termination symbol after the first LPWUS information, it determines that it will not detect the subsequent MOs of the first beam.

[0200] In some embodiments, the termination terminator is not part of the LPWUS information of the first MO; for example, the termination terminator is placed after the LPWUS information of the first MO.

[0201] For example, Figure 18 A schematic diagram is shown of the termination symbol placed at the last MO. (See diagram). Figure 18 As shown, if the woken-up subgroups are the 2nd and 4th subgroups, the network device can send the code point value 001 of the 2nd subgroup in MO1 and the code point value 011 of the 4th subgroup in MO2, in ascending order of code point value.

[0202] For MO1: If the code point value of the subgroup to which the terminal device belongs is 000, then the terminal device stops detecting MO2. If the code point value of the subgroup to which the terminal device belongs is 001, then the terminal device wakes up and establishes the service. If the code point value of the subgroup to which the terminal device belongs is greater than 001, then the terminal device continues to detect MO2.

[0203] Regarding MO1: Since the terminal device detects a termination symbol at MO2, it stops detecting MO3 regardless of the code point value of the subgroup to which it belongs. Furthermore, when the code point value of the subgroup to which the terminal device belongs is 011, the terminal device can still wake up and establish a service.

[0204] It should be noted that the above embodiments are illustrated by the example of the network device sending LPWUS information sequentially in ascending order of code point values, and placing a termination character after the LPWUS information of the last MO. This does not limit the scope of this application. In other embodiments, the network device may also send LPWUS information sequentially in descending order of code point values, and place a termination character after the LPWUS information of the last MO; or, the network device may send the LPWUS information of the woken-up subgroup in a random order in the first Y MOs, and place a termination character after the LPWUS information of the last MO.

[0205] In the above embodiment, when the first MO is the last MO among the MOs used to transmit LPWUS information under the first beam, by setting a termination symbol in the first MO, the terminal device can be informed that the current MO is the last MO among the MOs used to transmit LPWUS information under the first beam. The network device will not transmit LPWUS information in the subsequent MOs of the first beam. In this way, the terminal device can stop detecting the subsequent MOs of the first beam, thereby reducing the power consumption of the terminal device.

[0206] Example 2: Add N1 bits to the LPWUS information of the first MO to indicate the number of code points transmitted.

[0207] In this embodiment, the first MO is the first MO of at least one MO. The indication information of the first MO is carried in the LPWUS information of the first MO. This indication information can be used to indicate the number of code point values ​​transmitted through at least one MO. For example, an N1-bit information field is added to the LPWUS information of the first MO. The value of this information field can be used to indicate the number of code point values ​​transmitted through at least one MO. Here, N1 is a positive integer.

[0208] In some embodiments, the indication information of N1 bits is placed at any position in the LPWUS information of the first MO.

[0209] For example, Figure 19 A schematic diagram of N1 bits and code point values ​​is shown. (See diagram below.) Figure 19 As shown, the indication information of N1 bits can be placed before the code point value; or, the indication information of N1 bits can be placed after the code point value; or, the indication information of N1 bits can be placed in the middle of the code point value.

[0210] In some embodiments, the indication information of N1 bits is encoded together with the code point value of the first MO or encoded independently.

[0211] In some embodiments, the "number of code point values ​​transmitted through at least one MO" is divided into two cases: one case is that the code point values ​​transmitted through at least one MO include only non-repeating code point values; the other case is that the code point values ​​transmitted through at least one MO include both repeating and non-repeating code point values.

[0212] In some embodiments, the network device may set an information field in each of at least one MO, and the information field of each MO may be used to indicate that: the code point value of the next MO is a repeated code point value, or the code point value of the next MO is a non-repeating code point value, or no further code point values ​​will be transmitted.

[0213] In some embodiments, the interaction process between network devices and terminal devices is as follows:

[0214] Step 1: The network device transmits LPWUS information in the first Y MOs of X MOs through the first beam according to the number of awakened subgroups, and carries indication information in the LPWUS information of the first MO in the first Y MOs. This indication information can be used to indicate the number of code point values ​​transmitted in the first Y MOs.

[0215] In some embodiments, the LPWUS information transmitted in the first Y MOs indicates the code point value of the subgroup, and the network device can transmit the code point values ​​in the first Y MOs in ascending order, and place a terminating terminator after the LPWUS information of the last MO in the first Y MOs.

[0216] Step 2: The terminal equipment detects the MO of the first beam.

[0217] Step 3: The terminal device detects the first LPWUS information in the first MO of the first beam and decodes the first LPWUS information to obtain the code point value and indication information of a subgroup.

[0218] In some embodiments, the first LPWUS information may include a preamble, code point value, and CRC scrambling information.

[0219] Step 4: The terminal device determines whether to detect subsequent MOs of the first beam based on the code point value of a subgroup and the number of code point values ​​transmitted through at least one MO.

[0220] For example, Figure 20 A schematic diagram of N1-bit indication information is shown. For example... Figure 20As shown, the LPWUS information of MO1 carries N1 bits of indication information and 3 bits of code point value. The N1 bits of indication information are used to indicate the two non-repeating code point values ​​sent in the first two MOs. The network device sends code point value 011 in MO1 and code point value 110 in MO2. In this way, when the terminal device detects the indication information, it can only detect MO1 and MO2, without detecting subsequent MOs, thereby reducing the power consumption of the terminal device.

[0221] When each of at least one MO is provided with an information field, and the information field of each MO is used to indicate: the code point value of the next MO is a repeated code point value, or the code point value of the next MO is a non-repeating code point value, or no further code point values ​​will be transmitted, after determining that subsequent MOs of the first beam should be detected, the method may further include: decoding the information field of each MO; and determining whether to detect subsequent MOs of the first beam based on the decoding result of the information field of the current MO, the decoding result of the LPWUS information of the current MO, and the number of code point values ​​transmitted through at least one MO.

[0222] For example, Figure 21 This diagram illustrates setting an information field in each of the first Y MOs. (Example) Figure 21 As shown, the LPWUS information in MO1 carries N1 bits of indication information and 3 bits of code point value. The N1 bits of indication information are used to indicate the two non-repeating code point values ​​transmitted in the previous two MOs. The network device transmits code point value 011 in MO1, code point value 011 in MO2, and code point value 110 in MO3. Specifically, the information field of MO1 indicates that the code point value of the next MO is a repeating code point value, the information field of MO2 indicates that the code point value of the next MO is a non-repeating code point value, and the information field of MO3 indicates that no further code point values ​​will be transmitted. Taking the code point value of the terminal device as 111 as an example... When the terminal device detects an information field in MO1 but successfully decodes LPWUS, it can skip MO2 and proceed to MO3 for detection. When the terminal device detects an information field in MO1 but fails to decode LPWUS, it can detect MO2 and proceed to MO3 if LPWUS is successfully decoded in MO2. When the terminal device detects an information field in MO3, it will not perform subsequent MO detections regardless of whether LPWUS decoding is successful.

[0223] In the above embodiment, by adding N1 bits to the LPWUS information of the first MO to indicate the number of code points to be transmitted, the terminal device can determine the number of code points to be received based on these N1 bits, and only detect the first Y MOs corresponding to these code points, instead of detecting X MOs sequentially, thereby reducing the power consumption of the terminal device and shortening the detection time.

[0224] Example 3: The number of actual transmitted code points is indicated based on the different time-domain offset values.

[0225] In this embodiment, the first MO is the first MO of at least one MO, and the indication information of the first MO is the time domain offset of the first MO. The time domain offset is used to indicate the number of code point values ​​transmitted through at least one MO. The time domain offset is the time deviation between the start time of the first MO and a preset reference point.

[0226] In some embodiments, the preset reference point is predefined or determined based on the network configuration.

[0227] In some embodiments, different numbers of wake-up subgroups correspond to different time-domain offsets.

[0228] For example, Figure 22 This diagram illustrates how different numbers of awakened subgroups correspond to different time-domain offsets. For example... Figure 22 As shown, MO1 represents the first MO, offset1 represents the time-domain offset corresponding to Y = 1 MO, offset2 represents the time-domain offset corresponding to Y = 2 MO, offset3 represents the time-domain offset corresponding to Y = 3 MO, offset4 represents the time-domain offset corresponding to Y = 4 MO, offset5 represents the time-domain offset corresponding to Y = 5 MO, offset6 represents the time-domain offset corresponding to Y = 6 MO, offset7 represents the time-domain offset corresponding to Y = 7 MO, and offset8 represents the time-domain offset corresponding to Y = 8 MO. Here, Y is the number of awakened subgroups.

[0229] In some embodiments, the interaction process between network devices and terminal devices is as follows:

[0230] Step 1: The network device determines the first time domain offset based on the number of woken subgroups, and takes the time of the first time domain offset from the preset reference point as the starting time, and sends LPWUS information in at least one MO through the first beam.

[0231] In some embodiments, the LPWUS information transmitted in the first Y MOs indicates the code point value of the subgroup, and the network device can transmit the code point values ​​in the first Y MOs in ascending order.

[0232] Step 2: The terminal device detects the first MO based on different time-domain offsets. The time-domain offset is the time deviation between the start time of the first MO and the preset reference point. Different time-domain offsets are used to indicate the number of different code point values.

[0233] Step 3: At the moment when the terminal device is at the first time domain offset from the preset reference point, it detects the first LPWUS information at the first MO and decodes the first LPWUS information to obtain the code point value of a subgroup.

[0234] In some embodiments, the first LPWUS information may include a preamble, code point value, and CRC scrambling information.

[0235] Step 4: The terminal device determines whether to detect the subsequent MO of the first beam based on the number of code point values ​​indicated by the first time-domain offset and the decoding result of the first LPWUS information.

[0236] For example, Figure 23 A schematic diagram illustrating the number of code point values ​​for the woken subgroups based on time-domain offsets is shown. For example... Figure 23 As shown, when the network device wakes up the terminal devices in the 3rd and 5th subgroups, it can start at the time of the time offset 2 from the preset reference point, sending code point value 010 at MO1 and code point value 100 at MO2. If the terminal device detects the first LPWUS information at the time of the time offset 2' from the preset reference point in MO1, and decodes the first LPWUS information to obtain code point value 010, since the time offset 2 indicates two code point values, the terminal device can determine whether to perform MO2 detection based on code point value 100. For example, if the code point value of the subgroup to which the terminal device belongs is less than 010, then MO2 detection is not performed; if the code point value of the subgroup to which the terminal device belongs is equal to 010, then the terminal device wakes up and establishes service; if the code point value of the subgroup to which the terminal device belongs is greater than 010, then the terminal device continues to perform MO2 detection. It should be noted that regardless of the detection result of MO2, the terminal device stops detecting MO3.

[0237] In the example above, offset2' satisfies any of the following conditions: 1. offset1 < offset2' ≤ offset2; 2. offset2 ≤ offset2' < offset3; 3. |offset2' - offset2| ≤ △, where △ is a preset deviation value. It can be understood that the method of determining the actual time-domain offset offseti' based on the preset time-domain offset offseti is similar to the method of determining the actual time-domain offset offset2' based on the preset time-domain offset offset2, and will not be elaborated further here. Here, i is a positive integer.

[0238] In the above embodiments, by configuring different time-domain offsets, the network device can indicate the number of code point values ​​transmitted by controlling the time-domain offset. This allows the network device to perform MO detection based on different time-domain offsets and determine the actual number of transmitted code points, thus assisting in subsequent detection. Since at most the first Y MOs are detected, instead of sequentially detecting X MOs, the power consumption of the terminal device is reduced, and the detection time is shortened.

[0239] Example 4: The number of code points to be transmitted is carried according to the sequence information of the preamble and / or the overlaid sequence information of the preamble sequence.

[0240] In this embodiment, the first MO is the first MO of at least one MO, and the indication information of the first MO is the preamble sequence of the LPWUS information of the first MO or the overlaid sequence of the preamble sequence. The preamble sequence of the LPWUS information of the first MO or the overlaid sequence of the preamble sequence is used to indicate the number of code point values ​​transmitted through at least one MO. Different preamble sequences or different overlaid sequences of preamble sequences are used to indicate different numbers of code point values.

[0241] In some embodiments, different preamble sequences or different preamble sequence overlaid sequences are used to indicate different numbers of code point values, including any one of the following:

[0242] ① Different preamble sequences are used to indicate different numbers of code point values. Different preamble sequences refer to different sequence values. For example, preamble sequence 0000 is used to indicate no code point value is carried (i.e., this preamble sequence is a traditional preamble sequence and does not have the function of indicating the number of code point values ​​transmitted through at least one MO), preamble sequence 0001 is used to indicate carrying 1 code point value, preamble sequence 0010 is used to indicate carrying 2 code point values, and preamble sequence 0011 is used to indicate carrying 3 code point values.

[0243] ② Sequence categories of different preamble sequences are used to indicate different numbers of code point values.

[0244] ③ Overlaid sequences of different preamble sequences are used to indicate different numbers of code point values.

[0245] ④ The sequence category of the overlaid sequence of different preamble sequences is used to indicate different numbers of code point values.

[0246] In some embodiments, the preamble sequence or the overlaid sequence of the LPWUS information of each MO in at least one MO is used to indicate the number of code point values ​​transmitted through at least one MO.

[0247] For example, Figure 24 A schematic diagram is shown that indicates the number of code point values ​​using a preamble sequence. For example... Figure 24 As shown, the network device sends preamble sequence 1 at MO1, preamble sequence 2 at MO2, and preamble sequence 3 at MO3. Preamble sequence 1 uses a sequence value, such as 0011, to indicate the three code point values ​​transmitted through the first three MOs; preamble sequence 2 uses a different sequence value, such as 0000, and does not indicate the number of code point values ​​transmitted through at least one MO.

[0248] For example, Figure 25 This diagram illustrates another method of indicating the number of code point values ​​using a preamble sequence. (For example...) Figure 25 As shown, the network device transmits preamble sequence 1 in MO1, MO2, and MO3. Preamble sequence 1 uses a sequence value, such as 0011, to indicate the three code point values ​​transmitted in the first three MOs.

[0249] In some embodiments, the interaction process between network devices and terminal devices is as follows:

[0250] Step 1: The network device transmits LPWUS information in the first Y MOs of X MOs through the first beam according to the number of awakened subgroups, and carries indication information in the preamble sequence or the overlaid sequence of the LPWUS information of the first MO in the first Y MOs. The indication information can be used to indicate the number of code point values ​​transmitted in the first Y MOs.

[0251] In some embodiments, the LPWUS information transmitted in the first Y MOs indicates the code point value of the subgroup, and the network device can transmit the code point values ​​in the first Y MOs in ascending order.

[0252] Step 2: The terminal equipment detects the MO of the first beam.

[0253] Step 3: The terminal device detects the first LPWUS information in the first MO of the first beam and decodes the first LPWUS information to obtain the code point value and indication information of a subgroup. The indication information is the preamble sequence of the first LPWUS information or the overlaid sequence of the preamble sequence. The preamble sequence of the first LPWUS information or the overlaid sequence of the preamble sequence can be used to indicate the number of code point values ​​transmitted through at least one MO.

[0254] In some embodiments, the first LPWUS information may include a preamble, code point value, and CRC scrambling information.

[0255] Step 4: The terminal device determines whether to detect subsequent MOs of the first beam based on the code point value of a subgroup and the number of code point values ​​transmitted through at least one MO.

[0256] For the specific implementation of step 4, please refer to the description of the above embodiments, which will not be repeated here.

[0257] In the above embodiments, the network device can use the sequence information of the LPWUS preamble and / or the overlaid sequence information of the preamble sequence to carry the number of code points to be transmitted, enabling the terminal device to determine the number of code points to be received based on the sequence information of the preamble and / or the overlaid sequence information of the preamble sequence. Since the terminal device only needs to detect the first Y MOs at most, instead of detecting the X MOs sequentially, the power consumption of the terminal device is reduced and the detection time is shortened.

[0258] Example 5: Based on the sequence information of the preamble and / or the overlaid sequence information of the preamble sequence, the first MO is indicated to be the last MO among at least one MO in the first beam.

[0259] In this embodiment, the first MO is the last MO among at least one MO, and the indication information of the first MO is the preamble sequence of the LPWUS information of the first MO or the overlaid sequence of the preamble sequence. The preamble sequence of the LPWUS information of the first MO or the overlaid sequence of the preamble sequence is a first sequence, which is used to indicate that the first MO is the last MO among at least one MO under the first beam.

[0260] For example, Figure 26 A schematic diagram is shown illustrating how the last MO is indicated by a preamble sequence. (See diagram for example.) Figure 26As shown, the network device transmits preamble sequence a at MO1, preamble sequence a at MO2, and preamble sequence b at MO3. Preamble sequence a uses a sequence value, such as 00, which is a traditional preamble sequence; preamble sequence b uses another sequence value, such as 11, to indicate that the first MO is the last MO among at least one MO in the first beam.

[0261] In some embodiments, the interaction process between network devices and terminal devices is as follows:

[0262] Step 1: The network device transmits LPWUS information in the first Y MOs of X MOs through the first beam according to the number of awakened subgroups, and carries indication information in the preamble sequence or the overlaid sequence of the LPWUS information of the first MO in the first Y MOs. The indication information can be used to indicate the number of code point values ​​transmitted in the first Y MOs.

[0263] In some embodiments, the LPWUS information transmitted in the first Y MOs indicates the code point value of the subgroup, and the network device can transmit the code point values ​​in the first Y MOs in ascending order.

[0264] Step 2: The terminal equipment detects the MO of the first beam.

[0265] Step 3: The terminal device detects the first LPWUS information in the first MO of the first beam and decodes the first LPWUS information to obtain the code point value and indication information of a subgroup. The indication information is the preamble sequence of the first LPWUS information or the overlaid sequence of the preamble sequence. The preamble sequence of the first LPWUS information or the overlaid sequence of the preamble sequence is the first sequence. The first sequence is used to indicate that the first MO is the last MO among at least one MO in the first beam.

[0266] In some embodiments, the first LPWUS information may include a preamble, code point value, and CRC scrambling information.

[0267] Step 4: The terminal device determines not to detect subsequent MOs of the first beam based on the code point value of a subgroup and the number of code point values ​​transmitted through at least one MO.

[0268] For the specific implementation of step 4, please refer to the description of the above embodiments, which will not be repeated here.

[0269] In the above embodiments, when the first MO is the last MO among the MOs used to transmit LPWUS information under the first beam, the terminal device can be indicated by the sequence information of the preamble of the first MO and / or the overlaid sequence information of the preamble sequence. The network device will not transmit LPWUS information in the subsequent MOs of the first beam, so that the terminal device can stop detecting the subsequent MOs of the first beam, thereby reducing the power consumption of the terminal device.

[0270] Example 6: The number of code points to be sent is indicated by the scrambling information of LPWUS data or the scrambling information of CRC.

[0271] In this embodiment, the first MO is the first MO of at least one MO. The indication information of the first MO is carried in the scrambling information of the LPWUS information of the first MO. The indication information of the first MO is used to indicate the number of code point values ​​transmitted through at least one MO.

[0272] In some embodiments, the scrambling information of the LPWUS information includes at least one of the following:

[0273] The scrambling information of LPWUS data, which can be the code point value of the woken subgroup;

[0274] CRC scrambling information from LPWUS.

[0275] In some embodiments, the scrambling information of the LPWUS information of each of the first Y MOs carries indication information, which is used to indicate the number of code point values ​​transmitted through the first Y MOs.

[0276] For example, Figure 27 A schematic diagram illustrating the use of CRC sequences to indicate the number of code point values ​​is shown. For example... Figure 27 As shown, the network device can indicate the code point values ​​transmitted through the three MOs in the scrambling information of the LPWUS information of MO1, MO2, and MO3. This allows the terminal device to detect only MO1, MO2, and MO3. It should be noted that, as another possible implementation, the network device can indicate the code point values ​​transmitted through the three MOs only in the scrambling information of the LPWUS information of MO1, while the scrambling information of the LPWUS information of MO2 and MO3 does not carry the number of code point values.

[0277] In some embodiments, the interaction process between network devices and terminal devices is as follows:

[0278] Step 1: The network device transmits LPWUS information in the first Y MOs of X MOs through the first beam according to the number of awakened subgroups, and carries indication information in the scrambling information of the LPWUS information of the first MO in the first Y MOs. This indication information can be used to indicate the number of code point values ​​transmitted through at least one MO.

[0279] In some embodiments, the LPWUS information transmitted in the first Y MOs indicates the code point value of the subgroup, and the network device can transmit the code point values ​​in the first Y MOs in ascending order.

[0280] Step 2: The terminal equipment detects the MO of the first beam.

[0281] Step 3: The terminal device detects the first LPWUS information in the first MO of the first beam and decodes the first LPWUS information to obtain the code point value and indication information of a subgroup. The indication information is the scrambling information of the LPWUS information. The scrambling information is used to indicate the number of code point values ​​transmitted through at least one MO. The scrambling information of the LPWUS information includes at least one of the following: scrambling information of LPWUS data, and scrambling information of LPWUS cyclic redundancy check (CRC).

[0282] Step 4: The terminal device determines whether to detect subsequent MOs of the first beam based on the code point value of a subgroup and the number of code point values ​​transmitted through at least one MO.

[0283] For the specific implementation of step 4, please refer to the description of the above embodiments, which will not be repeated here.

[0284] In the above embodiments, the network device can use the scrambling information of LPWUS to carry the number of code points to be transmitted, so that the terminal device can determine the number of code points to be received based on the descrambling result of the LPWUS scrambling information. Since the terminal device only needs to detect the first Y MOs at most, instead of detecting the X MOs sequentially, the power consumption of the terminal device is reduced and the detection time is shortened.

[0285] Example 7: Carry the number of transmitted code points in the overlaid sequence information of LPWUS.

[0286] In this embodiment, the first MO is the first MO of at least one MO, and the indication information of the first MO is the overlaid sequence of the LPWUS information of the first MO. The overlaid sequence of the LPWUS information of the first MO is used to indicate the number of code point values ​​transmitted through at least one MO, and different overlaid sequences are used to indicate different numbers of code point values.

[0287] It should be noted that the difference between Embodiment 7 and Embodiment 4 is that Embodiment 4 carries the number of code points to be transmitted in the overlaid sequence information of the LPWUS preamble sequence, while Embodiment 7 carries the number of code points to be transmitted in the overlaid sequence information of the LPWUS. These two overlaid sequences are used to modulate the preamble sequence and LPWUS respectively to generate the final transmitted signal, but both overlaid sequences can be used to indicate different numbers of code point values.

[0288] In some embodiments, the interaction process between network devices and terminal devices is as follows:

[0289] Step 1: The network device transmits LPWUS information in the first Y MOs of X MOs through the first beam according to the number of awakened subgroups, and carries indication information in the overlaid sequence of the LPWUS information of the first MO in the first Y MOs. This indication information can be used to indicate the number of code point values ​​transmitted in the first Y MOs.

[0290] In some embodiments, the LPWUS information transmitted in the first Y MOs indicates the code point value of the subgroup, and the network device can transmit the code point values ​​in the first Y MOs in ascending order.

[0291] Step 2: The terminal equipment detects the MO of the first beam.

[0292] Step 3: The terminal device detects the first LPWUS information in the first MO of the first beam and decodes the first LPWUS information to obtain the code point value and indication information of a subgroup. The indication information is the scrambling information of the LPWUS information. The scrambling information is used to indicate the number of code point values ​​transmitted through at least one MO. The scrambling information of the LPWUS information includes at least one of the following: scrambling information of the LPWUS data and scrambling information of the LPWUS cyclic redundancy check (CRC).

[0293] In some embodiments, the first LPWUS information may include a preamble, code point value, and CRC scrambling information.

[0294] Step 4: The terminal device determines whether to detect subsequent MOs of the first beam based on the code point value of a subgroup and the number of code point values ​​transmitted through at least one MO.

[0295] For the specific implementation of step 4, please refer to the description of the above embodiments, which will not be repeated here.

[0296] In the above embodiments, the network device can use the LPWUS overlaid sequence to carry the number of code points to be transmitted, enabling the terminal device to determine the number of code points to be received based on the LPWUS overlaid sequence. Since the terminal device only needs to detect the first Y MOs at most, instead of detecting the X MOs sequentially, the power consumption of the terminal device is reduced and the detection time is shortened.

[0297] The above embodiments describe a subgroup information transmission method (referred to as the first seed group information transmission method): when a network device transmits LPWUS information in at least one of X MOs, the network device can indicate at least one of the following through the first MO among these at least X MOs: the first MO is the last MO among the at least X MOs in the first beam, and the number of code point values ​​transmitted through the at least X MOs. In addition, this application also provides two other subgroup information transmission methods (referred to as the second seed group information transmission method and the third seed group information transmission method).

[0298] The following examples illustrate the implementation methods of the other two subgroup information transmission methods.

[0299] For example, Figure 28 This is a flowchart illustrating the second seed group information transmission method provided in an embodiment of this application.

[0300] like Figure 28 As shown, the method may include the following steps S201 to S204.

[0301] S201. The network device transmits a first low-power synchronization signal (LPSS or LP-SS) sequence through a first beam. The first LPSS sequence is used to indicate the number of code point values ​​to be transmitted through the first beam at at least one MO.

[0302] In some embodiments, the network device can configure a correspondence between LPSS sequences or offset values ​​and the number of code point values. Different LPSS sequences are used to indicate different numbers of code point values.

[0303] In some embodiments, different LPSS sequences include any one of the following:

[0304] (1) Different LPSS sequences, where different preamble sequences refer to different sequence values ​​of the preamble sequences. For example, LPSS sequence 0000 is used to indicate carrying 1 code point value, LPSS sequence 0001 is used to indicate carrying 2 code point values, and LPSS sequence 0010 is used to indicate carrying 3 code point values.

[0305] (2) The offset values ​​of the LPSS sequence are different. For example, when the offset value of the LPSS sequence is the first value, it indicates that it carries 1 code point value; when the offset value of the LPSS sequence is the second value, it indicates that it carries 2 code point values; and when the offset value of the LPSS sequence is the third value, it indicates that it carries 3 code point values. For example, the LPSS of the cell is determined as sequence value ** according to relevant rules, and the sequence value ** is offset based on the value of Y. When Y = 0, no offset is made to the sequence value **; when Y = 1, the sequence value ** is offset by 1; and when Y = 2, the sequence value ** is offset by 2.

[0306] S202, The terminal device receives the first LPSS sequence through the first beam and determines the number of code point values ​​to be transmitted through the first beam at at least one MO based on the first LPSS sequence.

[0307] The terminal device can determine the number of code point values ​​to be transmitted through the first beam at at least one MO based on preset rules or network configuration rules, and based on the LPSS sequence.

[0308] S203. The network device transmits LPWUS information in at least one MO via the first beam. The LPWUS information transmitted in each MO is used to indicate the code point value of a subgroup in the woken subgroup.

[0309] S204. The terminal device detects at least one MO of the first beam and obtains LPWUS information. The LPWUS information detected in each MO is used to indicate the code point value of a subgroup in the woken-up subgroup.

[0310] For example, Figure 29 A schematic diagram is shown that indicates the number of code point values ​​using an LPSS sequence. For example... Figure 29 As shown, the LPSS sequence is a periodically transmitted sequence used for coarse synchronization between the network and terminal sides. Regardless of whether the network device needs to transmit LPWUS information, the LPSS sequence is continuously broadcast periodically within the cell. When the network device needs to transmit LPWUS information, it can use the sequence value or offset value of LPSS-1 to indicate the number of code points to be transmitted through the first beam at at least one MO, for example, code points to be transmitted in three MOs. Thus, when the terminal device decodes LPSS-1, it can determine that code points will be transmitted in the three MOs and detect MO1, MO2, and MO3 respectively.

[0311] In the aforementioned subgroup information transmission method, the network device can use the LPSS sequence to carry the number of code points to be transmitted, enabling the terminal device to determine the number of code points to be received based on the LPSS sequence. Since the terminal device only needs to detect the first Y MOs at most, instead of detecting the X MOs sequentially, the power consumption of the terminal device is reduced, and the detection time is shortened.

[0312] For example, Figure 30 This is a flowchart illustrating the third seed group information transmission method provided in an embodiment of this application.

[0313] like Figure 30 As shown, the method may include the following steps S301 to S304.

[0314] S301. The network device sends first LPWUS information through the first beam in the first MO. The first LPWUS information is used to indicate the code point value of the first subgroup in the woken subgroup. The first MO is a preset MO corresponding to the first subgroup.

[0315] S302. The terminal device detects the first LPWUS information in the first MO of the first beam, and determines whether to detect the subsequent MOs of the first MO based on the decoding result of the first LPWUS information.

[0316] S303. The network device transmits second LPWUS information through the first beam in the second MO. The second LPWUS information is used to indicate the code point value of the second subgroup in the woken subgroup. The second MO is the preset MO corresponding to the second subgroup.

[0317] S304. The terminal device detects the second LPWUS information in the second MO of the first beam, and determines whether to detect the subsequent MOs of the second MO based on the decoding result of the second LPWUS information.

[0318] The first and second subgroups mentioned above are different subgroups, and different subgroups correspond to different preset MOs.

[0319] It should be noted that since the terminal device corresponds to only one MO, such as the first MO or the second MO, the terminal device only detects one of the first MO and the second MO, that is, it only executes the above S302 or S304.

[0320] As an example, when X is 2, the first half of the subgroups are detected in the first MO, and the second half of the subgroups are detected in the second MO.

[0321] As another example, when X is 2, subgroups with odd index values ​​are detected in the first MO, and subgroups with even index values ​​are detected in the second MO.

[0322] In some embodiments, assuming there are M subgroups, the subgroups can be divided into X groups. The number of subgroups allocated to each group in sequence is either floor(M / X)+1 or floor(M / X). The first mod(M,X) MOs are allocated floor(M / X)+1 subgroups, and the subsequent MOs are allocated floor(M / X) subgroups. Thus, each subgroup needs to detect one position. Here, floor() is the floor function.

[0323] In some embodiments, the terminal device can determine the LPWUS information detected in the MO based on the subgroup ID mod X, and obtain the value of the code point. Here, mod is the modulo symbol.

[0324] In some embodiments, the correspondence between subgroups and MOs is preset or determined according to network configuration.

[0325] For example, Figure 31 This diagram illustrates grouping the positions of different code points according to the number of X MOs transmitted. For example... Figure 31 As shown, if the woken-up subgroups are the 1st and 8th subgroups, the network device can perform the following calculations: 1mod3 = 1, 8mod3 = 2, thus sending the code point value 000 for the 1st subgroup at MO1 and the code point value 111 for the 8th subgroup at MO2. In this way, terminal devices belonging to the 1st subgroup can detect only MO1, and terminal devices belonging to the 8th subgroup can detect only MO2.

[0326] In the above subgroup information transmission method, by pre-fixing the correspondence with MO, the network device can only send LPWUS information at fixed positions. Accordingly, the terminal device only needs to detect the fixed positions, instead of blindly detecting X MOs, thereby reducing the power consumption of the terminal device.
