Description

Communication demodulation methods, base stations, and storage media This application claims priority to Chinese Patent Application No. 202510392121.3, filed on March 28, 2025, entitled "Communication Demodulation Method, Base Station and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of communication technology, and in particular to communication demodulation methods, base stations, and storage media. Background Technology With the development of IoT technology, IoT devices are widely used in smart homes, industrial automation, smart cities, environmental monitoring, and many other fields. The IoT connects various smart devices, systems, and applications via the internet, enabling seamless information exchange and intelligent processing. In IoT technology, power management of terminal devices is a crucial challenge. Currently, terminal devices can establish a communication connection with the network and begin listening for paging signals during the paging process, thereby receiving service signals. To reduce power consumption, terminal devices can increase the number of wake-up opportunities. During the wake-up opportunity, the terminal device can begin listening for low-power wake-up signals. Once the terminal device detects a low-power wake-up signal, it can establish a communication connection with the network and begin listening for paging signals during the next paging opportunity, thereby receiving service signals. Otherwise, if the terminal device does not detect a low-power wake-up signal, it can choose not to begin listening for paging signals during the next paging opportunity. However, when there are many terminal devices in a communication system, network devices cannot allocate a different paging and wake-up time for each terminal device. Therefore, there is an urgent need for a strategy to allocate paging and wake-up times for terminal devices to reduce false alarms from other terminal devices during paging or wake-up times. Summary of the Invention This application provides a communication demodulation method, a base station, and a storage medium, which are applied in the field of communication technology. The method realizes the predefinition of configuration information for the mapping relationship between MO and subgroups corresponding to different PO, and realizes the demodulation of terminal devices based on the predefined configuration information. Firstly, embodiments of this application propose a communication demodulation method. Applied to a base station, the method includes: Send configuration information to the terminal device; wherein the configuration information indicates that the subgroup monitoring the same MO monitors different POs, and the configuration information indicates the index indication of the subgroup monitoring the same MO corresponding to different POs, and the subgroup includes at least one terminal device; The configuration information is used by the terminal device for demodulation processing. In this embodiment, by dynamically allocating PO monitoring tasks, different subgroups under the same MO can monitor different POs, thereby reducing UE monitoring conflicts and improving paging efficiency. The mapping relationship between subgroups of each MO and different POs is clearly defined by the index indication. In one possible implementation, the index indicates the PO index of the different POs monitored by the subgroup of the MO being detected, and the index obtained by combining the first subgroup index of the subgroup corresponding to each PO of the MO being detected. In this embodiment, the mapping relationship of subgroups of different POs corresponding to each MO is accurately identified by the index indication composed of PO index + first subgroup index, so that the base station can flexibly configure the monitoring strategy of different subgroups. In one possible implementation, the PO index represents an index obtained by processing the sorting sequence number of different POs corresponding to the subgroups of detected MOs. In this embodiment, the scalability of paging scheduling is improved by indexing the different PO sorting numbers in the MO. In one possible implementation, the first subgroup index represents the index obtained by processing the sorting sequence number of the subgroup corresponding to each PO. In this embodiment, the scalability of paging scheduling is improved by indexing subgroup numbers. In one possible implementation, the first subgroup index is the index obtained by combining the set index of the terminal device set corresponding to PO and the second subgroup index of the subgroup in the terminal device set; the terminal device set includes multiple subgroups, and each terminal device set contains the same number of subgroups. In this embodiment, by expanding the first subgroup index into a two-level index consisting of a set index and a second subgroup index, finer-grained subgroup grouping management is achieved, thereby improving the scalability of paging scheduling. In one possible implementation, the set index represents the index obtained by processing the sorting sequence number of the set of terminal devices corresponding to each PO. In this embodiment, the scalability of paging scheduling is improved by indexing the sorted sequence numbers of the terminal devices. In one possible implementation, the second subgroup index represents the index obtained by processing the sorting sequence number of the subgroups in each set of terminal devices. In this embodiment, the scalability of paging scheduling is improved by indexing the internal sequence numbers of the terminal device set. In one possible implementation, the index is the index obtained by processing the sorting sequence number of the subgroup corresponding to each PO; and the configuration information indicates the correspondence between the communication protocol parameters and the PO; the communication protocol parameters are the parameters contained in the data information transmitted between the base station and the terminal equipment during the communication process. In this embodiment, by associating POs with protocol parameters, the terminal device can determine the PO listening strategy according to the protocol parameters. By implementing differentiated paging, it is suitable for mixed service scenarios (such as simultaneously serving voice, data, and emergency communication protocol parameters and subgroup indexes, generating a mapping relationship between subgroups of different POs in each MO). In one possible implementation, configuration information is sent to the terminal device, including: Send data information to the terminal device; the communication protocol of the data information contains configuration information; or, the data content of the data information includes configuration information. In this embodiment, demodulation on the terminal device side is achieved through multiple methods based on configuration information, thereby improving the flexibility of configuration information synchronization. Secondly, embodiments of this application propose a communication demodulation method. Applied to a terminal device, the method includes: Obtain configuration information sent by the base station; wherein the configuration information indicates that the subgroup monitoring the same MO monitors different POs, and the configuration information indicates the index indication of the subgroup monitoring the same MO corresponding to different POs, and the subgroup includes at least one terminal device; Demodulation is performed based on the configuration information. In this embodiment, by uniformly configuring the mapping relationship between subgroups and POs in the base station, differentiated listening of terminal devices under the same MO is achieved, effectively reducing the probability of listening conflicts between terminal devices and improving the system paging capacity. Simultaneously, through the standardized definition of index indicators, it is ensured that terminal devices can accurately resolve their own subgroups and corresponding POs, achieving precise demodulation. In one possible implementation, the index indicates the PO index of the different POs monitored by the subgroup of the MO being detected, and the index obtained by combining the first subgroup index of the subgroup corresponding to each PO of the MO being detected. In this embodiment, the mapping relationship of subgroups of different POs corresponding to each MO is accurately identified by the index indication composed of PO index + first subgroup index, so that the base station can flexibly configure the monitoring strategy of different subgroups. In one possible implementation, the PO index represents an index obtained by processing the sorting sequence number of different POs corresponding to the subgroups of detected MOs. In this embodiment, the scalability of paging scheduling is improved by indexing the different PO sorting numbers in the MO. In one possible implementation, the first subgroup index represents the index obtained by processing the sorting sequence number of the subgroup corresponding to each PO. In this embodiment, the scalability of paging scheduling is improved by indexing subgroup numbers. In one possible implementation, the first subgroup index is the index obtained by combining the set index of the terminal device set corresponding to PO and the second subgroup index of the subgroup in the terminal device set; the terminal device set includes multiple subgroups, and each terminal device set contains the same number of subgroups. In this embodiment, by expanding the first subgroup index into a two-level index consisting of a set index and a second subgroup index, finer-grained subgroup grouping management is achieved, thereby improving the scalability of paging scheduling. In one possible implementation, the set index represents the index obtained by processing the sorting sequence number of the set of terminal devices corresponding to each PO. In this embodiment, the scalability of paging scheduling is improved by indexing the sorted sequence numbers of the terminal devices. In one possible implementation, the second subgroup index represents the index obtained by processing the sorting sequence number of the subgroups in each set of terminal devices. In this embodiment, the scalability of paging scheduling is improved by indexing the internal sequence numbers of the terminal device set. In one possible implementation, the index is the index obtained by processing the sorting sequence number of the subgroup corresponding to each PO; and the configuration information indicates the correspondence between the communication protocol parameters and the PO; the communication protocol parameters are the parameters contained in the data information transmitted between the base station and the terminal equipment during the communication process. In this embodiment, by associating POs with protocol parameters, the terminal device can determine the PO listening strategy according to the protocol parameters. By implementing differentiated paging, it is suitable for mixed service scenarios (such as simultaneously serving voice, data, and emergency communication protocol parameters and subgroup indexes, generating a mapping relationship between subgroups of different POs in each MO). In one possible implementation, demodulation processing is performed based on configuration information, including: When the configuration information is set in the communication protocol of the data information, the data information is demodulated according to the configuration information of the communication protocol; or, When configuration information is set in the data content of the data information, the demodulation rules of the terminal device are configured according to the data content. This embodiment provides a flexible configuration information transmission mechanism that supports both efficient implicit transmission at the protocol layer and detailed explicit configuration at the data layer, ensuring that the solution can adapt to terminal devices with different capability levels and enabling flexible allocation of terminal devices.

Before describing the technical solutions of the embodiments of this application, examples of communication systems to which the embodiments of this application can be applied will be given first. For example, embodiments of this application may be applied to, but are not limited to, the following communication systems: second-generation (2G) communication systems, third-generation (3G) communication systems, narrowband Internet of Things (NB-IoT) systems, wireless local access network (WLAN) systems, long-term evolution (LTE) systems, vehicle-to-X (V2X) wireless communication systems, fifth-generation mobile networks (5G), also known as new radio (NR) systems, LTE and 5G hybrid architectures, 5G new radio (5G NR) systems, communication systems after 5G, such as 6G systems, device-to-device (D2D) communication systems, etc. A communication system includes network equipment and terminals. Network equipment is the device on the network side used to provide network communication functions; it is sometimes also called a network element. Network equipment can typically be a base station, a functional unit of a base station, or a combination of functional units of a base station. An example of a communication system is shown in Figure 1, which includes a base station and terminal equipment. In the embodiments provided in this application, the base station can be any device with wireless transceiver capabilities, including but not limited to: evolved base stations (NodeB, eNB, or e-NodeB) in Long Term Evolution (LTE), base stations (gNodeB or gNB) or transmission receiving points / transmission reception points (TRPs) in New Radio (NR), base stations in subsequent 3GPP evolutions, access nodes, wireless relay nodes, and wireless backhaul nodes in Wi-Fi systems. The base station can be: a macro base station, a micro base station, a pico base station, a small cell, a relay station, or a balloon station, etc. The base station can include one or more co-located or non-co-located Transmission Reception Points (TRPs).

The base station can communicate with the terminal, or it can communicate with the terminal through a relay station. The terminal can communicate with multiple base stations using different technologies. For example, the terminal can communicate with base stations that support LTE networks, base stations that support 5G networks, and can also establish dual connections with both LTE and 5G base stations. In the embodiments provided in this application, the terminal can take various forms, such as a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, vehicle-mounted terminal device, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, wearable terminal device, etc. The terminal may also be referred to as terminal equipment, user equipment (UE), access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, UE terminal equipment, terminal equipment, wireless communication equipment, UE agent, or UE device, etc. The terminal can also be a fixed terminal or terminal equipment. Figure 1 illustrates an example of a communication system architecture applicable to embodiments of this application. Figure 1 includes a base station and multiple terminals. The base station can send demodulation rules to the terminal devices, or the base station can write the demodulation rules into the protocol of the signal data sent to the terminal devices. Since Rel-16, the 3rd Generation Partnership Project (3GPP) has been researching energy-saving technologies for 5G terminals. 5G terminal equipment introduces a low-power wake-up receiver (LP-WUR) to handle wake-up signals, building upon existing communication units. As shown in Figure 2, a UE can include a main receiver (MR) and a low-power receiver (LR). The LR can be a low-power wake-up receiver (LP-WUR). The UE can receive a low-power wake-up signal (LP-WUS) by adding an LP-WUR. LP-WUS is a low-power wake-up signal designed for small, power-sensitive, static, and slow-moving devices. Since the LP-WUR consumes significantly less power than the main receiver (MR), having the LP-WUR listen for LP-WUS and wake up the MR upon detecting LP-WUS, and then listen to the PDCCH subframe, can significantly reduce UE power consumption and achieve power saving. During this process, terminals such as the UE can enable the Discontinuous Reception (DRX) mechanism. DRX allows the UE to periodically enter sleep mode. In sleep mode, the UE does not listen to PDCCH subframes. When listening is required, it wakes up from sleep mode. When the UE enters sleep mode, the DRX period is in idle state. In idle mode, when the UE uses LP-WUS for listening, the primary radio receiver (MR) can be in sleep mode. When the UE detects LP-WUS, it triggers a switch in the MR state, waking up the MR and initiating listening to the PDCCH or receiving paging messages. If the UE does not detect LP-WUS, the MR remains in sleep mode, and the UE does not initiate listening to the PDCCH or receive paging messages. The base station can group terminal devices within its range into multiple subgroups. Based on these subgroups, the base station can predefine the paging occasion (PO) for each MR (Mobile Receiver). The PO is specifically the time point at which the MR in the UE listens for paging messages. Furthermore, based on the subgroup corresponding to the PO, the base station can also predefine the monitoring occasion (MO) for each LR (Low-Level Receiver). The MO is specifically the time point at which the LR in the UE listens for LP-WUS. The base station can then distribute this predefined mapping between PO, MO, and subgroups to the terminal devices, enabling them to determine the demodulation rules for the corresponding subgroup based on the predefined configuration principles and perform the appropriate demodulation. RAN1 meetings 117 and 120 proposed a predefined protocol for the correspondence between POs, MOs, and subgroups. This protocol supports dividing UEs monitoring the same PO into multiple subgroups. In one implementation, UEs monitoring the same PO can correspond to the same MO. For example, as shown in Figure 3(a). When PO1 and PO2 are included, UEs monitoring PO1 can correspond to MO1, and UEs monitoring PO2 can correspond to MO2. However, this will reduce the number of MOs corresponding to each PO. In another implementation, UEs corresponding to different POs can correspond to the same LO. In yet another implementation, UEs corresponding to the same PO can be divided into multiple subgroups, with UEs within each subgroup corresponding to the same MO. For example, as shown in Figure 3(b). When PO1 includes 32 subgroups, 16 subgroups in PO1 can correspond to MO1, and another 16 subgroups in PO1 can correspond to MO2. The same applies to PO2. However, this will reduce the number of subgroups for each PO. To address the aforementioned shortcomings, this application proposes a communication demodulation method. The method will be described in detail below using embodiments shown in Figures 4 to 7. Example 1 Figure 4 shows an index indication diagram of the mapping relationship between MO and subgroup provided in an embodiment of this application. The mapping relationship between MO, PO and subgroup is shown in Figure 5. The base station is configured or predefined with the total number of subgroups corresponding to each PO, the number of subgroups indicated by each MO, and the index indication of the subgroups associated with each MO. For example, for each PO, the base station configures or predefines the total number of subgroups corresponding to the PO. Here, a subgroup is a terminal device subgroup, and a terminal device subgroup includes multiple terminal devices. For each MO, the base station configures or predefines the number of subgroups indicated by the MO and the index indication of the subgroups associated with the MO. In one example, the index indicator may include a PO index and a subgroup index. The PO index represents the PO index, and the subgroup index represents the index indicator of the subgroup associated with the MO. In one example, the number of POs indicated by each MO is configured or predefined. The number of bits in the PO index can be determined based on the number of POs corresponding to that MO. The following example illustrates this: In one example, the number of POs corresponding to the same MO is typically 2 or 4. Optionally, the number of POs corresponding to the same MO can be a power of 2, such as 8, 16, 32, etc. In one example, when the number of POs corresponding to the same MO is 2, the PO index can include 1 bit. When the number of POs corresponding to the same MO is 4, the PO index can include 2 bits. When the number of POs corresponding to the same MO is 8, the PO index can include 3 bits, and so on. This setting ensures that each PO can correspond to one value in the PO index. Alternatively, the value can be indicated by all the bits in the PO index. In one example, when MO includes PO1 and PO2, the PO index can include 1 bit. Based on this 1 bit, a value of [0] corresponds to PO1, and a value of [1] corresponds to PO2. In one example, when MO includes PO1, PO2, PO3, and PO4, the PO index can include 2 bits. Based on these 2 bits, when the value of this bit is...

[0000] This can correspond to PO1, when the value of this bit is...

[0001] When the value of this bit is

[0010] , it can correspond to PO2; when the value of this bit is

[0011] , it can correspond to PO3; and when the value of this bit is

[0011] , it can correspond to PO4. In one example, when MO includes 8 POs, the PO index can include 3 bits. The values ​​of the 3 bits corresponding to the 8 POs can be represented as

[0000] ,

[0001] ,

[0010] ,

[0011] ,

[0100] ,

[0101] ,

[0110] , and

[0111] . In one example, when the number of POs included in MO is greater than 8, the number of bits and the value of the PO index can be deduced accordingly. For example, the number of POs corresponding to different MOs may be the same or different. In one example, multiple MOs may have the same number of POs. For example, MO1 may correspond to 2 POs, and MO2 may also correspond to 2 POs. In one example, there can be multiple MOs corresponding to different numbers of POs. For example, MO1 can correspond to 2 POs, and MO2 can correspond to 3 POs. In one example, there can be multiple MOs, some of which correspond to the same number of POs, while others correspond to different numbers of POs. For example, MO1 can correspond to 2 POs, MO2 can also correspond to 2 POs, and MO3 can correspond to 3 POs. For example, the number of subgroups for each MO indication can be configured or predefined. In one example, the number of subgroups indicated by each MO is related to the predefined number of POs indicated by each MO. For each MO, after determining the number of bits for the PO index based on the number of POs indicated by the MO, the number of bits for the subgroup index can be determined based on the difference between the total number of bits in the MO's code point and the number of bits for the PO index. Based on the number of bits for the subgroup index, the number of indices that the subgroup index can indicate can be determined. Furthermore, for each MO, the number of subgroups indicated by the MO can be determined based on the predefined number of POs indicated by the MO and the number of indices that the subgroup index can indicate. The maximum number of subgroups corresponding to each PO in the MO is the same. For example, when an MO code point includes 5 bits and the MO corresponds to 2 POs, the PO index includes 1 bit and the subgroup index includes 4 bits. The maximum number of subgroups corresponding to a PO is 16. For example, the demodulation information can be predefined to allocate 16 subgroups out of the 32 subgroups corresponding to the PO to the MO. In one example, similar to the PO index, the subgroup index can also use the value of its corresponding multiple bits as the index of the subgroup corresponding to the PO in the MO. For example, when 16 of the 32 subgroups corresponding to the PO are predefined to be assigned to the MO, the subgroup index of the first subgroup among the 16 subgroups can be...

[0000] The subgroup index of the second subgroup can be

[0001] The subgroup index of the third subgroup can be

[0010] And so on. In one example, the demodulation relation can also predefine how each subgroup in the PO is mapped to a different MO. For example, the mapping from subgroups in the PO to multiple MOs can be achieved by modulo operation. In one example, when it is necessary to map a subgroup of a PO to two MOs, odd MOs can be used to associate odd-numbered subgroups in the PO, and even MOs can be used to associate even-numbered subgroups in the PO. For example, when the PO contains 8 subgroups, the 1st, 3rd, 5th, and 7th subgroups correspond to MO1, and the 2nd, 4th, 6th, and 8th subgroups correspond to MO2. In one example, when it is necessary to map a subgroup of a PO to 4 MOs, the subgroups of the PO with a remainder of 0 modulo 4 can be mapped to MO1, the subgroups of the PO with a remainder of 1 modulo 4 can be mapped to MO2, the subgroups of the PO with a remainder of 2 modulo 4 can be mapped to MO3, and the subgroups of the PO with a remainder of 3 modulo 4 can be mapped to MO4. When you need to map a subgroup of a PO to 8 MOs, you can use the subgroup in the PO modulo 8 and determine its corresponding MO based on the remainder. When you need to map a subgroup of a PO to 9 MOs, you can use the subgroup in the PO modulo 9 and determine its corresponding MO based on the remainder. And so on. For example, the mapping of subgroups in the PO to multiple MOs can be achieved by sequential partitioning. In one example, when it is necessary to map a PO's subgroups to two MOs, a sequential allocation method can be used. The first half of the subgroups corresponding to the PO can be assigned to MO1, and the second half can be assigned to MO2. For example, when the PO contains 32 subgroups, subgroups 1-16 can be assigned to MO1, and subgroups 17-32 can be assigned to MO2. In one example, when it's necessary to map a PO's subgroups to four MOs, a sequential allocation method can be used. The first quarter of the subgroups corresponding to the PO can be assigned to MO1, the second quarter to MO2, the third quarter to MO3, and the fourth quarter to MO4. For instance, when the PO contains 32 subgroups, subgroups 1-8 can be assigned to MO1, subgroups 9-16 to MO2, subgroups 17-24 to MO3, and subgroups 25-32 to MO4. In one example, when you need to map a subgroup of a Product Owner (PO) to 8 Items of Interest (MOs), you can divide the subgroups in the PO into 8 groups in sequence and map them sequentially to different MOs. When you need to map a subgroup of a PO to 9 MOs, you can divide the subgroups in the PO into 9 groups in sequence and map them sequentially to different MOs. And so on. In one example, a predefined bitmap can be used to map subgroups in a PO to multiple MOs. Specifically, each MO and PO can correspond to a bitmap. This bitmap can indicate the subgroups in the PO that need to be mapped to the MO. For example, when PO1 contains 8 subgroups, the bitmap of PO1 corresponding to MO1 can be [01001011]. Based on this bitmap, the 2nd, 5th, 7th, and 8th subgroups in PO1 can be mapped to MO1. For example, predefined bits are used to indicate the subgroup index in the LP-WUS. Optionally, there can be multiple such bits. Optionally, the positions of these multiple bits in the LP-WUS can start from the first bit of the LP-WUS. In one example, the first 2 bits of LPWUS are defined to indicate the index of the subgroup. For example, the terminal device determines the demodulation rules corresponding to the subgroup to which it belongs based on the configured or predefined rules, and performs the corresponding demodulation. Example 2 Figure 5 shows an index indication diagram of the mapping relationship between MO and subgroup provided in an embodiment of this application. The mapping relationship between MO, PO and subgroup is shown in Figure 6. The base station is configured or predefined to have a number of subgroup sets for each PO, and each PO's subgroup set includes at least one subgroup of the PO. In one example, each PO corresponds to multiple subgroups. The subgroups of each PO are predefined or configured to be divided into more granular rules, so that the subgroups of each PO are divided into different subgroup sets, resulting in the subgroup sets of each PO. For example, for each PO, the base station configures or predefines the number of subgroup sets for each PO. It can also predefine or configure finer-grained partitioning rules for each PO's subgroups. These partitioning rules can be predefined or explicitly indicated to determine the subgroup partitioning granularity for each PO. Alternatively, the partitioning granularity can be indicated by a predefined table. Based on this partitioning granularity, the number of subgroup sets and the number of bits in the indicated subgroups can be determined. In one example, the set index can be determined based on the number of sets in the subset, and the subgroup number can be determined based on the number of subgroups in the subset. For example, when 32 subgroups in a PO are divided into 2 sets of subgroups, each set of subgroups can include 16 subgroups. Similarly, when 32 subgroups in a PO are divided into 4 sets of subgroups, each set of subgroups can include 8 subgroups. For example, the subgroup set in the PO can be partitioned by taking the modulo. In one example, when it is necessary to divide the subgroups of a PO into two subgroup sets, you can divide the odd-numbered subgroups into subgroup set 1 and the even-numbered subgroups into subgroup set 2. For example, when the PO contains 8 subgroups, the 1st, 3rd, 5th, and 7th subgroups are divided into subgroup set 1, and the 2nd, 4th, 6th, and 8th subgroups are divided into subgroup set 2. In one example, when it is necessary to divide a PO into 4 subgroup sets, the subgroups of the PO with a remainder of 0 modulo 4 can be divided into subgroup set 1, the subgroups of the PO with a remainder of 1 modulo 4 can be divided into subgroup set 2, the subgroups of the PO with a remainder of 2 modulo 4 can be divided into subgroup set 3, and the subgroups of the PO with a remainder of 0 modulo 3 can be divided into subgroup set 4. In one example, when you need to divide a PO's subgroups into 8 subgroup sets, you can use the subgroups in the PO modulo 8 and determine the corresponding subgroup set based on the remainder. When you need to divide a PO's subgroups into 9 subgroup sets, you can use the subgroups in the PO modulo 9 and determine the corresponding subgroup set based on the remainder. And so on. For example, the mapping of subgroups in the PO to multiple MOs can be achieved by sequential partitioning. In one example, when it is necessary to divide the subgroups of a Product Owner (PO) into two subgroup sets, a sequential allocation method can be used. The first half of the subgroups corresponding to the PO can be assigned to subgroup set 1, and the second half can be assigned to subgroup set 2. For example, when the PO contains 32 subgroups, subgroups 1-16 can be assigned to subgroup set 1, and subgroups 17-32 can be assigned to subgroup set 2. In one example, when it's necessary to divide a Product Owner (PO) into four subgroup sets, a sequential allocation method can be used. The first quarter of the subgroups corresponding to the PO can be assigned to subgroup set 1, the second quarter to subgroup set 2, the third quarter to subgroup set 3, and the fourth quarter to subgroup set 4. For instance, when the PO contains 32 subgroups, subgroups 1-8 can be assigned to subgroup set 1, subgroups 9-16 to subgroup set 2, subgroups 17-24 to subgroup set 3, and subgroups 25-32 to subgroup set 4. In one example, when you need to map a subgroup of a Product Owner (PO) to 8 subgroup sets, you can divide the subgroups in the PO into 8 groups in sequence and map them sequentially to different subgroup sets. When you need to map a subgroup of a PO to 9 subgroup sets, you can divide the subgroups in the PO into 9 groups in sequence and map them sequentially to different subgroup sets. And so on. For example, a predefined bitmap can be used to divide the subgroups in the PO into multiple sets of subgroups. In one example, each set of subgroups and PO can correspond to a bitmap. This bitmap can indicate which subgroup in the PO should correspond to the MO. For example, when PO1 contains 8 subgroups, the bitmap of PO1 corresponding to subgroup set 1 can be [01001011]. Based on this bitmap, the 2nd, 5th, 7th, and 8th subgroups in PO1 can be mapped to subgroup set 1. In one example, after partitioning the subgroup set, each PO's multiple subgroup sets can be mapped to multiple MOs respectively. Optionally, the number of subset sets mapped to different MOs can be different. For example, when a PO includes two subset indices, subset index 1 can be mapped to MO1, and subset index 2 can be mapped to MO2. Similarly, when a PO includes four subset indices, subset indices 1 and 2 can be mapped to MO1, and subset indices 3 and 4 can be mapped to MO2. For example, the mapping relationship can be implemented using PO index, set index, and subgroup number points to index the MO and subgroups. The use of the PO index is the same as in Example 2. The number of bits in the set index can be determined based on the number of subgroup sets corresponding to the MO. The number of bits in the subgroup number points can be determined based on the number of subgroups in the subgroup set. For example, in the process of mapping different subgroup sets corresponding to a PO to multiple MOs in the mapping information, the mapping of different subgroup sets corresponding to a PO to MOs can be achieved through predefined mapping rules. The aforementioned "predefined correspondence rules" can be implemented by taking the modulo operation to correspond the subgroup set in the PO to multiple MOs. In one example, when it is necessary to map a subset of a PO to two MOs, odd MOs can be used to associate odd-numbered subsets of the PO, and even MOs can be associated with even-numbered subsets of the PO. For example, when the PO contains 4 subsets, the 1st and 3rd subsets correspond to MO1, and the 2nd and 4th subsets correspond to MO2. In one example, when it is necessary to map a set of subgroups of a PO to 4 MOs, the subgroups of the PO with a remainder of 0 modulo 4 can be mapped to MO1, the subgroups of the PO with a remainder of 1 modulo 4 can be mapped to MO2, the subgroups of the PO with a remainder of 2 modulo 4 can be mapped to MO3, and the subgroups of the PO with a remainder of 3 modulo 4 can be mapped to MO4. In one example, when you need to map a subset of a PO to 8 MOs, you can use the subset of the PO modulo 8 and determine the corresponding MO based on the remainder. When you need to map a subset of a PO to 9 MOs, you can use the subset of the PO modulo 9 and determine the corresponding MO based on the remainder. And so on. The aforementioned "predefined correspondence rules" can be implemented in a sequential partitioning manner to correspond the subgroup set in the PO to multiple MOs. In one example, when it is necessary to map a set of subgroups of a PO to two MOs, a sequential allocation method can be used. The first half of the subgroups in the set corresponding to the PO can be assigned to MO1, and the second half can be assigned to MO2. For example, when the PO includes 4 subgroups, the 1st and 2nd subgroups can be assigned to MO1, and the 3rd and 4th subgroups can be assigned to MO2. In one example, when it's necessary to map a set of subgroups of a Product Owner (PO) to four Item Modules (MOs), a sequential allocation method can be used. The first quarter of the subgroups corresponding to the PO can be assigned to MO1, the second quarter to MO2, the third quarter to MO3, and the fourth quarter to MO4. For instance, when the PO contains eight subgroups, the first and second subgroups can be assigned to MO1, the third and fourth to MO2, the fifth and sixth to MO3, and the seventh and eighth to MO4. In one example, when you need to map a subset of a Product Object (PO) to 8 Items of Interest (MOs), you can divide the subset of the PO into 8 parts in sequence and map them sequentially to different MOs. When you need to map a subset of a PO to 9 MOs, you can divide the subset of the PO into 9 parts in sequence and map them sequentially to different MOs. And so on. The aforementioned "predefined mapping rules" can be implemented using predefined bitmaps or similar methods to map the set of subgroups in the PO to multiple MOs. Specifically, each MO and PO can correspond to a bitmap. This bitmap can indicate the set of subgroups in the PO that needs to be mapped to the MO. In one example, when PO1 contains 8 subgroup sets, the bitmap of PO1 corresponding to MO1 can be [01001011]. Based on this bitmap, the 2nd, 5th, 7th, and 8th subgroup sets in PO1 can be mapped to MO1. For example, the terminal device determines the demodulation rules corresponding to the subgroup to which it belongs based on the configured or predefined principles, and performs the corresponding demodulation. Example 3 Figure 6 shows an index indication diagram of the mapping relationship between MO and subgroup provided in an embodiment of this application. The mapping relationship between MO, PO and subgroup is shown in Figure 7. The base station configures or predefines the correspondence between the preamble sequence and the PO. And / or, the base station configures or predefines the correspondence between the postamble sequence and the PO. And / or, the base station configures or predefines the correspondence between the Cyclic Redundancy Check (CRC) scrambling sequence and the PO. And / or, the base station configures or predefines the correspondence between CRC mask sequences and PO. And / or, the base station configures or predefines the relationship between the overlaid sequence and the indicated PO. For example, the base station can configure or predefine the correspondence between the preamble sequence and the PO. In one example, a single bit of the preamble can be used as an identifier. Based on the value of this bit, the corresponding PO can be determined. For example, if the value of this bit is [0], it corresponds to PO1, and if the value of this bit is [1], it corresponds to PO2. In one example, a single byte of the preamble can be used as an identifier sequence. Based on this identifier sequence, the corresponding point of sale (PO) can be determined. For example, if the sequence of bits for this byte is [00000000], it corresponds to PO1. Similarly, if the sequence is [11111111], it corresponds to PO2. Likewise, if the sequence is [11110000], it corresponds to PO3. And if the sequence is [00001111], it corresponds to PO4. In one example, a sequence of consecutive bits from the preamble can be obtained as an identifier. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, a sequence of non-contiguous bits forming an identifier can be obtained from the preamble. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, the entire sequence of the preamble can be obtained as the identifier sequence. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, multiple identifier sequences of the preamble can be predefined to correspond to a single point of interest (PO). For instance, the identifier sequences of the preamble [00110011], [00000011], and [11110011] can correspond to PO1. Similarly, the identifier sequences of the preamble [00110111], [00000111], and [11110111] can correspond to PO2. For example, the base station can configure or predefine the correspondence between the Postamble sequence and the PO. In one example, a single bit of the Postamble can be used as an identifier. The value of this bit determines the corresponding Postamble Point (PO). For example, a value of [0] corresponds to PO1, and a value of [1] corresponds to PO2. In one example, a single byte of the Postamble can be used as an identifier sequence. Based on this identifier sequence, the corresponding Postamble Point (PO) can be determined. For example, if the sequence of bits for this byte is [00000000], it corresponds to PO1. Similarly, if the sequence is [11111111], it corresponds to PO2. Likewise, if the sequence is [11110000], it corresponds to PO3. And if the sequence is [00001111], it corresponds to PO4. In one example, a sequence of consecutive bits from the Postamble can be obtained as an identifier. Based on this identifier sequence, the corresponding Postamble Point (PO) can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, a sequence of non-contiguous bits forming an identifier can be obtained from the postamble. Based on this identifier sequence, the corresponding postamble (PO) can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, the entire sequence of the Postamble can be obtained as the identifier sequence. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, multiple identifier sequences for the Postamble can be predefined to correspond to a PO. For instance, the identifier sequences of the Postamble [00110011], [00000011], and [11110011] can correspond to PO1. Similarly, the identifier sequences of the Postamble [00110111], [00000111], and [11110111] can correspond to PO2. For example, the base station can configure or predefine the correspondence between the CRC scrambling sequence and the PO. In one example, a single bit of the CRC scrambling sequence can be used as an identifier. The corresponding PO can be determined based on the value of this bit. For example, if the value of this bit is [0], it corresponds to PO1; if the value of this bit is [1], it corresponds to PO2. In one example, a field of the CRC scrambling sequence can be obtained as an identifier sequence. Based on this identifier sequence, the corresponding PO can be determined. For example, if the sequence of bits for this byte is [00000000], it corresponds to PO1. Similarly, if the sequence is [11111111], it corresponds to PO2. Again, if the sequence is [11110000], it corresponds to PO3. And if the sequence is [00001111], it corresponds to PO4. In one example, a sequence of consecutive bits from the CRC scrambling sequence can be used to form an identifier. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, a non-contiguous sequence of bits from the CRC scrambling sequence can be used to form an identifier sequence. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, the entire CRC scrambling sequence can be obtained as the identifier sequence. Based on the identifier sequence of this byte, its corresponding PO can be determined. For example, if the identifier sequence is [00000000], it can correspond to PO1. As another example, if the identifier sequence is [11111111], it can correspond to PO2. In one example, multiple identifier sequences of the CRC scrambling sequence can be predefined to correspond to a single postamble (PO). For instance, the identifier sequences of the postamble [00110011], [00000011], and [11110011] can correspond to PO1. Similarly, the identifier sequences of the postamble [00110111], [00000111], and [11110111] can correspond to PO2. For example, the base station can configure or predefine the correspondence between the CRC mask sequence and the PO. In one example, a single bit of the CRC mask sequence can be used as an identifier. The corresponding PO can be determined based on the value of this bit. For example, if the value of this bit is [0], it corresponds to PO1; if the value of this bit is [1], it corresponds to PO2. In one example, a field of the CRC mask sequence can be obtained as the identifier sequence. Based on the identifier sequence of this byte, its corresponding PO can be determined. For example, if the sequence of each bit of this byte is [00000000], it corresponds to PO1. Similarly, if the sequence of each bit of this byte is [11111111], it corresponds to PO2. Again, if the sequence of each bit of this byte is [11110000], it corresponds to PO3. And if the sequence of each bit of this byte is [00001111], it corresponds to PO4. In one example, a sequence of consecutive bits from the CRC mask sequence can be used to form an identifier sequence. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, a non-contiguous sequence of bits from the CRC mask sequence can be used to form an identifier sequence. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, the entire sequence of the CRC mask can be obtained as the identifier sequence. Based on the identifier sequence of this byte, its corresponding PO can be determined. For example, if the identifier sequence is [00000000], it can correspond to PO1. As another example, if the identifier sequence is [11111111], it can correspond to PO2. In one example, multiple identifier sequences of the CRC mask sequence can be predefined to correspond to a PO. For example, the identifier sequences of the Postamble [00110011], [00000011], and [11110011] can correspond to PO1. Similarly, the identifier sequences of the Postamble [00110111], [00000111], and [11110111] can correspond to PO2. For example, the base station can configure or predefine the correspondence between overlaid and PO. In one example, a single bit of the OVERLAID sequence can be used as an identifier. The corresponding PO can be determined based on the value of this bit. For example, if the value of this bit is [0], it corresponds to PO1; if the value of this bit is [1], it corresponds to PO2. In one example, a field of the OVERLAID sequence can be obtained as an identifier sequence. Based on the identifier sequence of this byte, its corresponding PO can be determined. For example, if the sequence of each bit of this byte is [00000000], it corresponds to PO1. Similarly, if the sequence of each bit of this byte is [11111111], it corresponds to PO2. Again, if the sequence of each bit of this byte is [11110000], it corresponds to PO3. And if the sequence of each bit of this byte is [00001111], it corresponds to PO4. In one example, a sequence of consecutive bits from the OVERLAID sequence can be used to form an identifier sequence. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, a non-contiguous sequence of bits from the OVERLAID sequence can be used to form an identifier sequence. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, the entire OVERLAID sequence can be obtained as the identifier sequence. Based on this identifier sequence, the corresponding PO can be determined. For example, if the identifier sequence is [00000000], it corresponds to PO1. Similarly, if the identifier sequence is [11111111], it corresponds to PO2. In one example, multiple identifier sequences for the OVERLAID sequence can be predefined to correspond to a PO. For example, the identifier sequences of the Postamble [00110011], [00000011], and [11110011] can correspond to PO1. Similarly, the identifier sequences of the Postamble [00110111], [00000111], and [11110111] can correspond to PO2. For example, the terminal device determines the demodulation rules corresponding to the subgroup to which it belongs based on the configured or predefined principles, and performs the corresponding demodulation. Example 4 Figure 7 is a signaling interaction diagram of a communication demodulation method provided in an embodiment of this application. As shown in Figure 4, the base station can send predefined configuration information to the terminal device, and the terminal device performs demodulation according to the configuration information. Specifically, the method provided in this embodiment includes the following steps: Step 101: The base station sends demodulation information to the terminal device; wherein, the demodulation information indicates that subgroups monitoring the same MO are monitoring different POs, and the configuration information indicates the mapping relationship between subgroups monitoring the same MO corresponding to different POs, and the subgroups include at least one terminal device. The demodulation information is used by the terminal device for demodulation processing. The demodulation information includes configuration information or predefined rules. In this embodiment, the base station can send predefined configuration information to the terminal device. This configuration information includes the mapping relationship between MOs and POs corresponding to subgroups. This mapping relationship can be represented using index indicators. Specifically, the configuration information can indicate that subgroups detecting the same MO can detect different POs. For example, one subgroup can correspond to MO1 and PO1, and another subgroup can correspond to MO1 and PO2, where MO2 corresponds to PO1 and PO2 respectively (a more detailed description of the specific MOs and POs follows). Optionally, a subgroup may include at least one terminal device. Optionally, when multiple subgroups exist, each subgroup contains the same number of terminal devices. Optionally, terminal devices corresponding to the same PO can be grouped to obtain the subgroup. The base station can send this configuration information via dedicated RRC signaling configuration messages. Alternatively, the base station can send the configuration information via system information broadcast. The base station can also send the configuration information via dynamic configuration using MAC CE. (System messages, RRC signaling, MAC CE, and DCI downlink control signaling are also mentioned.) Step 102: The terminal device obtains the configuration information sent by the base station; wherein, the configuration information indicates that the subgroup monitoring the same MO monitors different POs, and the configuration information indicates the index indication of the subgroup monitoring the same MO corresponding to different POs, and the subgroup includes at least one terminal device. In this embodiment, the process of the terminal device receiving and processing configuration information mainly includes three main operations: information reception, information parsing, and information storage. In the information reception stage, in the first possible implementation, the terminal device obtains the configuration by listening to RRC signaling. In the second possible implementation, the terminal device obtains the configuration by reading system information blocks. In the third possible implementation, the terminal device reads the configuration from preset storage. All implementations must ensure the integrity and accuracy of the configuration information. Step 103: The terminal device performs demodulation processing based on the configuration information. In this embodiment, the terminal device performs configuration application and signal demodulation operations based on configuration information. In the configuration application phase, in the first possible implementation, the terminal device directly applies the received configuration parameters. In the second possible implementation, the terminal device needs to process the configuration information and, in the signal demodulation phase, perform precise listening according to the PO and MO indicated by the configuration information. This phased processing method ensures the efficiency and reliability of the paging process. (A detailed description of the specific demodulation process follows.) In this embodiment, a precise mapping relationship between MO and PO is established through predefined configuration information of the base station and then distributed to the terminal device to realize the mapping between MO and PO. The various allocation methods for subgroups in MO are clearly expanded. In one possible implementation, the specific process of demodulation between the terminal device and the base station based on configuration information may include: Step 201: The base station sends data information to the terminal device. The communication protocol for this data information includes configuration information. Alternatively, the data content being transmitted may include configuration information. In this embodiment, the base station typically sends data information to the terminal device in two ways: Firstly, configuration information is embedded in the communication protocol layer. Specifically, configuration parameters can be added to the protocol header field, configuration information can be carried in the control channel, or configuration can be transmitted through specific signaling messages. For example, the first 2 bits of LP-WUS are used to indicate the index of the subgroup. Secondly, the configuration information is included in the data content. Specifically, configuration fields can be added to the header of the data packet, configuration information can be inserted into the data payload, or configuration can be transmitted through dedicated data packets. Step 202: When the configuration information is set in the communication protocol of the data information, the terminal device demodulates the data information according to the configuration information in the communication protocol. Alternatively, when the configuration information is set in the data content of the data information, the terminal device configures the demodulation rules of the terminal device according to the data content. In this embodiment, based on the two methods of sending configuration information described above, the terminal device can perform different processes respectively. Firstly, when the configuration information is set in the communication protocol of the data information, the terminal device can parse the protocol field to obtain the configuration parameters, adjust the demodulation algorithm according to the parameter settings, and complete the demodulation processing of the data information. Secondly, when the configuration information is set in the data content of the data information, the terminal device extracts the configuration information from the data, updates the local demodulation rule configuration, and applies the new rules to perform data demodulation. In this embodiment, the advantages of the two implementation schemes are complementary. The protocol layer configuration offers higher real-time performance and reliability, making it suitable for rapid updates of key parameters. The data content configuration provides greater flexibility and compatibility, making it suitable for detailed transmission of complex configurations. The terminal device can select the optimal demodulation strategy according to its actual needs. Figure 8 is a schematic diagram of the structure of a communication demodulation device provided in an embodiment of this application. As shown in Figure 8, this embodiment of the application provides a communication demodulation device 200, which is applied to a base station and includes: The sending module 201 is used to send configuration information to the terminal device. The configuration information indicates that a subgroup monitoring the same MO is monitoring different POs, and also indicates the index of the subgroup monitoring the same MO corresponding to different POs, wherein the subgroup includes at least one terminal device. The configuration information is used by the terminal device for demodulation processing. In one possible implementation, the index indicates the PO index of the different POs monitored by the subgroup of the MO being detected, and the index obtained by combining the first subgroup index of the subgroup corresponding to each PO of the MO being detected. In one possible implementation, the PO index represents an index obtained by processing the sorting sequence number of different POs corresponding to the subgroups of detected MOs. In one possible implementation, the first subgroup index represents the index obtained by processing the sorting sequence number of the subgroup corresponding to each PO. In one possible implementation, the first subgroup index is a combination of the set index of the terminal device set corresponding to the PO and the second subgroup index of the subgroups within the terminal device set. The terminal device set includes multiple subgroups, and each terminal device set contains the same number of subgroups. In one possible implementation, the set index represents the index obtained by processing the sorting sequence number of the set of terminal devices corresponding to each PO. In one possible implementation, the second subgroup index represents the index obtained by processing the sorting sequence number of the subgroups in each set of terminal devices. In one possible implementation, the index is the index obtained by processing the sorting sequence number of the subgroup corresponding to each PO. The configuration information indicates the correspondence between communication protocol parameters and POs. Communication protocol parameters are the parameters included in the data information transmitted between the base station and the terminal equipment during the communication process. In one possible implementation, the sending module 201 is used for: Data information is sent to the terminal device. The communication protocol of the data information contains configuration information. Alternatively, the data content of the data information includes configuration information.

As shown in Figure 9, this embodiment of the application provides a communication demodulation device 300, which is applied to a terminal device and includes: The acquisition module 301 is used to acquire configuration information sent by the base station; wherein the configuration information indicates that the subgroup monitoring the same MO monitors different POs, and the configuration information indicates the index indication of the subgroup monitoring the same MO corresponding to different POs, and the subgroup includes at least one terminal device. The demodulation module 302 is used to perform demodulation processing based on the configuration information. In one possible implementation, the index indicates the PO index of the different POs monitored by the subgroup of the MO being detected, and the index obtained by combining the first subgroup index of the subgroup corresponding to each PO of the MO being detected. In one possible implementation, the PO index represents an index obtained by processing the sorting sequence number of different POs corresponding to the subgroups of detected MOs. In one possible implementation, the first subgroup index represents the index obtained by processing the sorting sequence number of the subgroup corresponding to each PO. In one possible implementation, the first subgroup index is the index obtained by combining the set index of the terminal device set corresponding to PO and the second subgroup index of the subgroup in the terminal device set; the terminal device set includes multiple subgroups, and each terminal device set contains the same number of subgroups. In one possible implementation, the set index represents the index obtained by processing the sorting sequence number of the set of terminal devices corresponding to each PO. In one possible implementation, the second subgroup index represents the index obtained by processing the sorting sequence number of the subgroups in each set of terminal devices. In one possible implementation, the index is the index obtained by processing the sorting sequence number of the subgroup corresponding to each PO; and the configuration information indicates the correspondence between the communication protocol parameters and the PO; the communication protocol parameters are the parameters contained in the data information transmitted between the base station and the terminal equipment during the communication process. In one possible implementation, the demodulation module 302 is used for: When the configuration information is set in the communication protocol of the data information, the data information is demodulated according to the configuration information of the communication protocol; or, When configuration information is set in the data content of the data information, the demodulation rules of the terminal device are configured according to the data content.
