Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to an information transmission method, apparatus, electronic device, readable storage medium, and computer program product. Background Technology

[0002] In wireless network communication, there are often multiple time slots between two consecutive downlink data scheduling sessions where no data transmission occurs on the Physical Downlink Control Channel (PDCCH). If the terminal continuously listens to the PDCCH during these time slots, it will result in significant power consumption waste. Therefore, the Discontinuous Reception (DRX) mechanism is introduced to address this situation. The User Equipment (UE) periodically listens to the PDCCH based on the DRX mechanism. Before the start of DRX On in each DRX cycle, it checks the Wake-Up Signal (WUS). The WUS signal indicates whether to wake up normally in the next DRX cycle, thus saving power. This reduces the terminal's listening time and power consumption. However, in the current DRX mechanism, waking up to check the WUS in each DRX cycle still results in excessively frequent WUS signal listening and high power consumption. Summary of the Invention

[0003] This application provides an information transmission method, apparatus, readable storage medium, and computer program product that can solve the problem that in the current DRX mechanism, the WUS signal still needs to be detected before each DRX cycle, which results in excessively frequent monitoring and high power consumption.

[0040] Figure 1 A schematic diagram of the structure of a wireless communication system provided in an embodiment of this application is shown. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several user equipment 110 and several base stations 120.

[0041] In this embodiment, user equipment 110 may be a device that provides voice and / or data connectivity to a user. User equipment 110 may communicate with one or more core networks via a Radio Access Network (RAN). User equipment 110 may be an Internet of Things (IoT) user equipment, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with IoT user equipment capabilities. For example, it may be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment. Alternatively, user equipment 110 may also be a device from an unmanned aerial vehicle (UAV). Alternatively, user equipment 110 may also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless user equipment connected to an external vehicle computer. Alternatively, User Equipment 110 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities. Alternatively, User Equipment 110 can also be a 5G Reduced Capability User Equipment (RedCap UE), which is a low-cost, low-power terminal designed for low-to-medium speed IoT and lightweight consumer devices in 5G networks. It simplifies capabilities such as bandwidth (e.g., supporting bandwidth up to 20MHz), number of antennas (e.g., a maximum of 2 receive and 1 transmit), and modulation method (e.g., up to 64QAM). For example, it could be an industrial sensor with wireless communication capabilities, a smart meter, a smart wearable device, or other reduced-capability terminals.

[0042] Base station 120 can be a network-side device in a wireless communication system. This wireless communication system can be based on fourth-generation mobile communication technology (the 4G). thThe 5G wireless communication system can be a next-generation mobile communication system, also known as a 4G (4G) system or a Long Term Evolution (LTE) system; alternatively, it can be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, it can be the next-generation system after 5G. In this system, the access network can be called NG. RAN (New Generation) Radio Access Network (a next-generation wireless access network).

[0043] The base station 120 can be an evolved NB (eNB) used in a 4G system. Alternatively, the base station 120 can be a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) layers; the distributed units are equipped with a physical (PHY) layer protocol stack. The specific implementation of the base station 120 is not limited in this embodiment.

[0046] Here, the user equipment described above can be considered as the terminal in the following embodiments.

[0047] In some embodiments, the wireless communication system described above may further include a network management device 130.

[0048] Several base stations 120 are connected to network management device 130. Network management device 130 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 130 is not limited in this embodiment.

[0049] To facilitate understanding of any embodiment of this application, the DRX mechanism of the terminal will first be explained.

[0050] Figure 2 A schematic diagram of a DRX cycle indicated by a WUS signal in related technologies is shown. For example... Figure 2 As shown, the DRX cycle includes a wake-up period (DRX On) and a sleep period. A sleep-wake signal (WUS) is introduced in the Radio Resource Control (RRC) connected state. WUS indicates whether the terminal needs to listen for PDCCH before the wake-up period of each DRX cycle. If there is no downlink data transmission, the terminal is instructed to sleep in the next DRX cycle. Otherwise, it continues to listen for PDCCH during the wake-up period of the next DRX cycle. For example, if the WUS signal is 1, the terminal wakes up normally in the next DRX cycle to receive DRX On data; if the WUS signal is 0, the terminal remains asleep in the next DRX cycle (indicated by the dashed line) until the next DRX cycle.

[0051] Before the start of the wake-up period of each DRX cycle, the WUS signal is carried by Downlink Control Information (DCI) format 2-6 to indicate the monitoring of PDCCH. The terminal needs to continuously monitor the WUS signal in the PDCCH search space and search time where DCI Format 2-6 is located several slots in advance before the start of each DRX cycle, and determine whether to execute DRX On normally based on the WUS indication.

[0052] In related technologies, using WUS (Wireless Use Signal) to indicate whether to enable DRX On in the next DRX cycle can achieve better UE power saving performance, with varying degrees of power saving effects in different scenarios such as FTP, instant messaging, and VoIP. Especially in non-urgent transmission and data burst scenarios, during periods without data bursts, the UE determines that DRX On is not needed by monitoring the WUS signal to be 0; in scenarios with data bursts, the WUS signal being 1 instructs the UE to wake up and perform data transmission and reception according to the DRX cycle, achieving ideal power saving results.

[0053] However, in actual implementation, some problems still exist with the relevant technologies:

[0054] First, the WUS signal needs to be received and detected before the start of each DRX cycle. Consequently, each DRX cycle requires finding the nearest synchronization signal and Physical Broadcast Channel Block (SSB) signal based on the start time of the WUS signal detection, instead of the original DRX On start time. This wakes the UE earlier for pre-synchronization and then monitors DCI Formats 2-6. In effect, this shortens the UE's deep sleep time within each DRX cycle and increases power consumption per DRX cycle. For example... Figure 3 As shown, the WUS signal is 0 for three consecutive DRX cycles, and there is no wake-up during each DRX cycle. While introducing WUS reduces power consumption during DRX On, it increases the power consumption of WUS. Furthermore, the SSB signal used for pre-synchronization needs to precede WUS, potentially leading to an earlier actual wake-up time and introducing additional power consumption. Therefore, in the current DRX mechanism, waking up to check WUS in each DRX cycle still suffers from excessively frequent WUS signal monitoring and high power consumption.

[0055] Second, the UE can only perform WUS signal listening according to a fixed DRX cycle. When the data burst cycle changes, such as when it changes from a frequent data burst scenario to a sparse data burst scenario, in the scenario with frequent data bursts (DRX On is turned on for service transmission for several consecutive DRX cycles) or in the scenario with no data bursts for a long time (no data transmission for several consecutive DRX cycles, so DRX On does not need to be turned on), it has to wake up for pre-synchronization and DCI detection 2-6 in each DRX cycle. The related technology cannot flexibly adapt to the changes in different scenarios. It still wakes up to perform WUS signal listening in the DRX cycle when no data burst transmission is needed, which increases the power consumption of WUS.

[0056] Third, with the large-scale deployment of 5G NR networks and the increase in the number of 5G users, RedCap UEs, enhanced mobile broadband (eMBB) UEs and other 5G terminals will coexist and operate in the same cell. How to simultaneously meet the service needs of different UEs under the DRX cycle and achieve better power saving performance has become a technical problem that urgently needs to be solved by those skilled in the art.

[0057] To address the aforementioned problems in the prior art, this application provides an information transmission method applicable to network-side devices and terminals.

[0058] The following will combine Figures 4 to 7 , Figures 9 to 12 The information transmission method applied to network-side devices provided in the embodiments of this application will be explained and described in detail. These embodiments are only used to explain this application and do not constitute a limitation on this application.

[0059] Figure 4 A flowchart illustrating an embodiment of the information transmission method provided in this application is shown. This information transmission method can be executed by a network-side device. Figure 4 As shown, this information transmission method mainly includes:

[0060] S401. Send downlink control information (DCI) to the terminal in discontinuous reception DRX cycle mode;

[0061] The DCI includes first indication information and second indication information; the first indication information and second indication information are adapted to different types of terminals respectively; the first indication information includes single sleep wake-up information to indicate that the corresponding type of terminal sleeps or wakes up in this DRX cycle; the second indication information includes DRX cycle sleep wake-up information to indicate that the corresponding type of terminal enters continuous sleep and / or continuous wake-up according to the DRX cycle sleep wake-up information.

[0062] In one embodiment, the base station sends a power-saving DCI (Distributed Instruction Code). The base station is an interface device for terminal access to the network. The base station can be of various types, such as a 3G network base station, a 4G network base station, a 5G network base station, or other evolved base stations.

[0063] The terminal in this embodiment is applicable to all types of NR terminals in wired communication networks. In one embodiment, the NR terminal may be, but is not limited to, a mobile phone, wearable device, vehicle terminal, smart home terminal, smart meter, industrial sensing device and / or medical device, etc.

[0064] In this embodiment, the network-side device categorizes terminals according to their type. Terminals of the same type (e.g., with consistent service requirements and functional support) are grouped together. Terminals in the same group adapt to the same indication information, while terminals in different groups adapt to different indication information. Terminals within the same group perform sleep / wake-up operations according to the same indication information. For example, in some embodiments, terminals can be grouped according to whether they support secondary cell sleep functionality. Terminals supporting secondary cell sleep functionality are grouped together, while terminals not supporting secondary cell sleep functionality, such as 5G RedCap UEs and other terminals that do not support multi-carrier and secondary cell sleep functionality, are grouped together. In some embodiments, the terminal type corresponding to the first indication information is a terminal that supports secondary cell sleep functionality, and the terminal type corresponding to the second indication information is a terminal that does not support secondary cell sleep functionality. For terminals adapting to the first indication information, after detecting DCI, they determine whether to perform a sleep or wake-up operation in the current DRX cycle based on the WUS signal. For terminals adapting to the second indication information, after detecting DCI, they enter continuous sleep and / or continuous wake-up according to the DRX cycle sleep / wake-up information.

[0065] In this embodiment, two different power-saving control mechanisms are implemented within the same DCI using indication information from different types of terminals, simultaneously supporting terminals with different capabilities and power consumption requirements. The first indication information is compatible with existing technologies that require listening to WUS before each DRX cycle to perform sleep or wake-up operations for that DRX cycle. The second indication information allows terminals with different service transmission needs and high power-saving requirements to reduce the number of WUS listening operations, enabling continuous sleep or wake-up for multiple DRX cycles, significantly reducing terminal listening frequency and power consumption.

[0066] In some embodiments, the DCI is DCI Format 2-6, and the first indication information and the second indication information are independent information unit blocks in DCI Format 2-6. To facilitate understanding of the DCI containing the first indication information and the second indication information in the embodiments of this application, the indication information of the DCI issued by the network-side device is described below.

[0067] Figure 5 This diagram illustrates the format of the indication information carried by existing WUS signals in a 5G NR system on DCI Format 2-6. (For example...) Figure 5As shown, the original DCI 2-6 includes N information unit blocks (Block0, Block1, ..., BlockN). Each block provides a set of indication information for a group of UEs, including: wakeup indication (Wakeup Ind) and secondary cell sleep indication (Scell ​​Dormancy Ind). Taking Block0 as an example, bit 0 of this block identifies the wakeup indication (Wakeup Ind), and bits 1-4 of this block respectively identify the sleep indications of the four secondary cells. In this example, a maximum of four groups of secondary cells can be indicated for their sleep status. Of course, the number of bits used to identify the wakeup indication and the secondary cell sleep indication in each block can be arbitrarily configured, and this application embodiment does not impose any restrictions. In addition, UEs belonging to the same group correspond to the same block in the DCI 2-6 payload, and the indication information provided by this block instructs UEs in the same group to perform the same sleep wakeup and secondary cell sleep behaviors.

[0068] In this embodiment, Figure 5 The N blocks in the original DCI Format 2-6 shown are divided into two categories. In this embodiment, the indication information includes two types: first indication information and second indication information. The first indication information includes one or more blocks, and the second indication information also includes one or more blocks. The first indication information supports the original DCI Format 2-6 format, i.e., it uses... Figure 5 The block indication information format is shown. The first indication information includes wake-up bits and secondary cell indication bits. The wake-up bits are identified by the wake-up identifier Wakeup Ind, and the secondary cell indication bits are identified by the secondary cell indication identifier Scelldormancy Ind.

[0069] In some embodiments, the second indication information supports the improved DCI Format 2-6 format. In some embodiments, the second indication information includes at least a periodic indication bit, or the second indication information includes a wake-up bit and a periodic indication bit; wherein the wake-up bit is used to identify the sleep or wake-up configuration state; and the periodic indication bit is used to identify DRX periodic sleep wake-up information. Figure 6 This illustration shows a schematic diagram of the indication information format on the improved DCI Format 2-6 provided in this application embodiment. For example, the N blocks on DCI Format 2-6 can be flexibly assigned the type of indication information, such as... Figure 6 As shown, the DCI includes both first indication information (such as Block 1) and second indication information (such as Block 0, Block N), as follows: Figure 6As shown, taking Block 0 as an example, bit 0 of this Block identifies the wakeup indicator, and bits 1-4 of this Block jointly identify DRX cycle sleep wake-up information, such as the DRX cycle number of wakeup or sleep. In some embodiments, the length of each Block remains unchanged, and the same Block length as the original DCI Formats 2-6 can be used for backward compatibility with UEs in the current network.

[0070] In practical implementation, non-RedCap UEs and UEs supporting secondary cells can be grouped together, and the first indication information in DCIFormat 2-6 can be used to perform DRX periodic wake-up or sleep. RedCap UEs, single-carrier terminals, or terminals that do not support secondary cells can be grouped together, and the second indication information in DCIFormat 2-6 can be used to perform DRX periodic wake-up or sleep. Therefore, the DCI issued by the network-side equipment in this embodiment can be compatible with terminals adapted to the first indication information and can also serve terminals adapted to the second indication information. It can simultaneously support terminals with different capabilities and power consumption requirements, and realize different power-saving control mechanisms.

[0071] In some embodiments, such as Figure 7 As shown, the information transmission method provided in this application embodiment further includes the following steps:

[0072] S701. Determine the corresponding indication information for the terminal based on its type;

[0073] S702. Send a first message to the terminal, wherein the first message includes: the resource location information of the indication information corresponding to the terminal in the DCI.

[0074] In some embodiments, the network-side device may divide the terminals into at least two groups according to whether the terminals support the secondary cell sleep function: at least one group of terminals that support the secondary cell sleep function, such as ordinary NR UEs; and at least one group of terminals that do not support the secondary cell sleep function, such as RedCap UEs.

[0075] After completing the grouping of terminal types, the first indication information in DCI Format2-6 is assigned to the terminals in the group that support the secondary cell sleep function, and the second indication information in DCI Format2-6 is assigned to the terminals in the group that do not support the secondary cell sleep function. The resource location information in DCI corresponding to the indication information of the terminal type is then sent to the corresponding terminal through the first message.

[0076] In some embodiments, the resource location information includes the start bit of the indication information corresponding to the terminal in the DCI, or the resource location information includes the start bit and the length of the indication information. For example, a terminal adapts to the second indication information to... Figure 6 Taking Block 0 as the second indication information as an example, bit 0 is carried as the starting bit of the second indication information in the DCI and sent to the terminal in the first message. The terminal listens to the DCI in the PDCCH search space, and takes bit 0 on the DCI as the starting bit. If it is compatible with the existing DCI Format 2-6 format, taking the length of each block as fixed at 5 bits as an example (the length of 5 bits is only for illustrative purposes and this application does not limit it), then it obtains the indication information of Block 0 (second indication information) by acquiring 5 consecutive bits of data. If the length of the block in the DCI Format 2-6 format is not fixed and the length of each block is not consistent, then the first message also needs to carry the indication information length. According to the indication information length, the corresponding number of bits of data are obtained to obtain the indication information of Block 0 (second indication information). For example, if the indication information length is 5 bits, then 5 consecutive bits of data are obtained to obtain the indication information of Block 0 (second indication information). Thus, the terminal can perform DRX cycle wake-up or sleep according to the second indication information.

[0077] In this embodiment, the DRX cycle sleep wake-up information in the second indication information can be used to instruct the corresponding type of terminal to enter continuous sleep and / or continuous wake-up. In some embodiments, the DRX cycle sleep wake-up information in the second indication information includes at least one of the following:

[0078] (1) Number of DRX cycles during continuous sleep or continuous wake-up;

[0079] (2) The number of DRX cycle units for continuous sleep or continuous wake-up, where one DRX cycle unit includes a preset number of DRX cycles;

[0080] (3) Sleep wake-up mode identifier, wherein the sleep wake-up mode identifier corresponds to the pre-configured DRX periodic sleep wake-up mode, so as to instruct the corresponding type of terminal to obtain the corresponding DRX periodic sleep wake-up mode according to the sleep wake-up mode identifier to enter continuous sleep or continuous wake-up.

[0081] In method (1), the DRX cycle sleep-wake information includes the number of consecutive sleep or wake-up cycles. For example, DRX cycle number = 4, Wakeup Ind = 0, indicating that it can sleep for 4 consecutive DRX cycles and wake up to re-listen to WUS before the 5th cycle. Another example is DRX cycle number = 3, Wakeup Ind = 1, indicating that it can wake up for 3 consecutive DRX cycles, but does not need to listen to WUS for those 3 cycles, and will re-listen to WUS before the 4th cycle. Thus, both methods reduce the number of WUS listeners, thereby reducing power consumption and achieving power saving.

[0082] In the DCIFormat2-6 format with a fixed instruction message length, Figure 6 Taking Block 0 as an example, if a Block only has 4 bits to identify the number of DRX cycles for continuous sleep or continuous wake-up, the maximum value can only be 16, which limits the setting of the number of cycles. Therefore, in method (2), in order to expand the number of DRX cycles for continuous sleep or continuous wake-up, this embodiment uses one DRX cycle unit as the base, and each cycle unit can be preset with a corresponding number of cycles. For example, one DRX cycle unit is equal to 1, 2 or 4 DRX cycles, etc., so that the number of DRX cycles can be expanded without being limited to 16. For example, if the number of DRX cycle units is 3, one DRX cycle unit = 2 DRX cycles, then the current number of DRX cycles = 6. The terminal can perform continuous sleep or continuous wake-up operations according to 6 DRX cycles, thereby realizing the expansion of the number of DRX cycles indicated by the fixed-length DCIFormat2-6.

[0083] In method (3), the DRX cycle sleep wake-up information only includes the sleep wake-up mode identifier. The network-side device pre-sends the pre-configured DRX cycle sleep wake-up mode corresponding to the sleep wake-up mode identifier to the terminal for storage. After obtaining the sleep wake-up mode identifier in the second indication information from the DCI, the corresponding type of terminal can query the corresponding DRX cycle sleep wake-up mode locally and perform continuous sleep or continuous wake-up operations according to the DRX cycle sleep wake-up mode indication. In some embodiments, the DRX cycle sleep wake-up mode includes: continuously waking up for N DRX cycles and then continuously sleeping for M DRX cycles, or continuously sleeping for N DRX cycles and then continuously waking up for M DRX cycles, where N and M are positive integers. For example, N=5, M=3, which means that it can continuously sleep for 5 DRX cycles and then continuously wake up for 3 DRX cycles. During these 8 consecutive cycles, it is not necessary to listen to WUS, and wake up before the 9th cycle to listen to WUS again. Thus, the number of WUS listening times can be reduced, thereby reducing power consumption and achieving the purpose of power saving.

[0084] In some embodiments, after grouping terminals according to whether they support secondary cell sleep function, terminals that do not support secondary cell sleep function can be further divided according to their service transmission requirements, further subdividing the service scenarios of different terminals. UEs performing the same or nearly the same sleep wake-up behavior are then further grouped together, and different second indication information is used to instruct different groups of UEs to perform corresponding sleep wake-up behaviors, thereby achieving more refined power-saving control. In some embodiments, determining the indication information corresponding to a terminal based on its type includes: when the terminal type is compatible with the second indication information, determining the second indication information corresponding to terminals with different service transmission requirements based on the terminal's service transmission requirements. The resource location information of the terminal-related indication information carried in the first message in the DCI includes: the resource location information of the second indication information corresponding to terminals with different service transmission requirements in the DCI. In this embodiment, the resource location information of the second indication information can also be sent to the terminal in advance via the first message, so that the terminal can obtain the corresponding second indication information from the DCI. For example, redCap UEs with frequent continuous data bursts are divided into one group, and redCap UEs with sparse data bursts are divided into another group. RedCap UEs with frequent continuous data bursts have continuous data transmission needs and can be woken up once every 2 DRX cycles. RedCap UEs with sparse data bursts may not have data transmission needs for a long time and can be woken up once every 4 DRX cycles. That is, terminals with different service transmission needs use different second indication information to subdivide the groups that do not support the secondary cell sleep function. The second indication information is used to instruct terminals in different groups to perform corresponding sleep and wake-up behaviors, thereby achieving more refined power saving control.

[0085] In actual implementation, different UEs have different service scenarios, and the actual sleep or wake-up time required is not consistent. Using the same second indication information to instruct UEs in the same group to perform the same sleep or wake-up behavior will result in some UEs experiencing data transmission delays and unnecessary power consumption. For example, in an application example, there are 4 UEs in a group. Assume that UE0 has no service transmission needs for a long time and can remain in sleep mode for a long time, UE1 needs to transmit data for several consecutive DRX cycles, and UE2 and UE3 have data transmission needs every 2 DRX cycles. The network-side equipment compromised by instructing all UEs in this group to enable DRX On every two DRX cycles for service transmission. For UE0, waking up every two DRX cycles for pre-synchronization and WUS detection and then enabling DRX On, compared to enabling DRX On every DRX cycle, can improve power saving. However, since UE0 does not actually have a service data transmission requirement, there is still unnecessary power consumption. For UE1, only half of the consecutive DRX cycles (e.g., DRX cycles 0 / 2 / 4...) can be used for data transmission. Compared to the original solution (which can transmit in every DRX cycle), there is some latency and the throughput is halved, but there is a 50% improvement in power saving. UE2 and UE3 fully meet their service scenario requirements, satisfying both data transmission needs and precise power saving, which is a significant improvement over the original solution. Overall, there is a power saving gain for all UEs in the group, but some UEs experience data transmission latency.

[0086] Therefore, Red Cap UEs with different business scenario requirements can be further subdivided, which can alleviate the problem of data transmission latency and achieve more precise power-saving control. For example, in the above application example, UE0 is assigned to the group with very little data transmission, UE1 is assigned to the group with frequent data transmission, and UE2 and UE3 are assigned to the group with moderate data transmission. Different groups use different second indication information (different blocks) in DCI Format 2-6 to indicate their sleep-wake behavior. For example, the block corresponding to UE0 can indicate to remain asleep for up to 16 / 32 / 64 DRX cycles (depending on the block's bit length m, it can support 2^(m-1) DRX cycles); the block corresponding to UE1 can indicate to continuously perform sleep-wake for up to 16 / 32 / 64 DRX cycles (depending on the block's bit length m, it can support 2^(m-1) DRX cycles); the blocks corresponding to UE2 and UE3 can indicate to wake up once every two DRX cycles. Therefore, further grouping can enable UEs with different service needs to receive appropriate power-saving control, resulting in better power-saving effects without sacrificing data transmission of other UEs in the same group.

[0087] This application example is particularly suitable for NR Red Cap UEs, which have low bandwidth and low throughput, do not support multi-carrier aggregation, and do not require secondary cell sleep, and have a strong need for power saving. By grouping Red Cap UEs camped on a single cell and other UEs that do not support secondary cell sleep into one category, and separating them from UEs that do support secondary cell sleep, and further dividing all UEs that do not support secondary cell sleep into different groups according to their working service scenarios, UEs with frequent data bursts are placed in the same group, and UEs with infrequent data bursts are placed in another group, so that UEs within the same group can achieve maximum power saving performance by performing the same sleep-wake behavior.

[0088] The information transmission method provided in this application embodiment enables two different power-saving control mechanisms within the same DCI using indication information from different types of terminals, simultaneously supporting terminals with different capabilities and power consumption requirements. The first indication information is compatible with the prior art where WUS monitoring is required before each DRX cycle to perform sleep or wake-up operations for that DRX cycle. The second indication information allows terminals with different service transmission needs and high power-saving requirements to reduce the number of WUS monitoring cycles, enabling continuous sleep or wake-up for multiple DRX cycles, significantly reducing terminal monitoring frequency and power consumption, resulting in noticeable power savings for the terminal.

[0089] The following will combine Figure 8 The information transmission method applied to a terminal provided in the embodiments of this application will be explained and described in detail. These embodiments are only used to explain this application and do not constitute a limitation on this application.

[0090] Figure 8 A flowchart of an exemplary embodiment of this application is shown, illustrating an information transmission method that can be executed by a terminal. This embodiment of the information transmission method executed by the terminal corresponds to the aforementioned embodiment of the information transmission method executed by a network-side device. In this embodiment, the focus is on a detailed description of the implementation method on the terminal side; other related parts are only briefly described. For relevant matters, please refer to the detailed description of the aforementioned method embodiment of the network-side device. Figure 8 As shown, the information transmission method provided in this application embodiment mainly includes the following steps (S801-S802):

[0091] S801. Obtain Downlink Control Information (DCI); wherein, DCI includes first indication information and second indication information; the first indication information and second indication information are adapted to different types of terminals respectively; the first indication information includes single sleep wake-up information to indicate that the corresponding type of terminal sleeps or wakes up in this DRX cycle; the second indication information includes DRX cycle sleep wake-up information to indicate that the corresponding type of terminal enters continuous sleep and / or continuous wake-up according to the DRX cycle sleep wake-up information.

[0092] In this embodiment, for the relevant descriptions of the first indication information and the second indication information, as well as the relevant descriptions of the first indication information and the second indication information being adapted to different types of terminals, please refer to the detailed description of the method embodiment of the network side device described above, which will not be repeated here.

[0093] S802. Obtain the indication information corresponding to the terminal from the DCI, and perform the sleep wake-up operation in the discontinuous reception DRX cycle mode according to the indication information corresponding to the terminal.

[0094] In this embodiment, before sending Downlink Control Information (DCI) to terminals in discontinuous reception DRX cycle mode, the network-side device first divides the terminals into different groups according to whether they support secondary cell sleep function, and determines the corresponding indication information for each terminal. For example, the first indication information in DCI Format 2-6 is assigned to terminals in the group supporting secondary cell sleep function, and the second indication information in DCI Format 2-6 is assigned to terminals in the group not supporting secondary cell sleep function. Then, the resource location information in the DCI corresponding to this type of terminal is sent to the corresponding terminal via a first message.

[0095] In some embodiments, the method provided in this application further includes: receiving a first message, the first message including resource location information of indication information corresponding to the terminal in the DCI. In some embodiments, obtaining indication information corresponding to the terminal from the DCI includes: obtaining indication information from the DCI according to the resource location information of the indication information corresponding to the terminal in the DCI. In some embodiments, the resource location information includes the start bit of the indication information corresponding to the terminal in the DCI, or the resource location information includes the start bit and the length of the indication information.

[0096] For example, the current terminal adapts to the second indication information, in order to Figure 6Taking Block 0 as the second indication information as an example, bit 0 is carried as the starting bit of the second indication information in the DCI and sent to the terminal in the first message. After the terminal detects the DCI in the PDCCH search space, it uses the resource location information of the corresponding indication information in the DCI obtained in advance, taking bit 0 on the DCI as the starting bit. If it is compatible with the existing DCI Format 2-6 format, taking a fixed length of 5 bits for each block as an example (the length of 5 bits is only for illustrative purposes and this application does not limit it), it obtains 5 consecutive bits of data to obtain the indication information of Block 0 (second indication information). If the length of the block in the DCI Format 2-6 format is not fixed and the length of each block is not consistent, it obtains the corresponding number of bits of data according to the length of the indication information carried in the first message to obtain the indication information of Block 0 (second indication information). For example, if the length of the indication information is 5 bits, it obtains 5 consecutive bits of data to obtain the indication information of Block 0 (second indication information). Thus, the terminal can obtain the corresponding indication information from the DCI so as to perform the corresponding DRX cycle wake-up or sleep operation according to the corresponding indication information.

[0097] In this embodiment, the terminal performs corresponding DRX cycle wake-up or sleep operations according to the corresponding indication information. In some embodiments, performing a sleep-wake operation in a discontinuous reception DRX cycle mode according to the corresponding indication information of the terminal includes:

[0098] The first indication information is the indication information corresponding to the terminal. The sleep or wake-up operation of this DRX cycle is performed according to the single sleep wake-up information.

[0099] In response to the terminal's corresponding indication information, which is the second indication information, sleep or wake-up operations for multiple consecutive DRX cycles are performed based on the DRX cycle sleep-wake information.

[0100] In some embodiments, the terminal type corresponding to the first indication information is a terminal that supports secondary cell sleep function, and the terminal type corresponding to the second indication information is a terminal that does not support secondary cell sleep function. For a terminal that adapts to the first indication information, after detecting DCI, it acquires the first indication information and determines whether to perform a sleep or wake-up operation in the current DRX cycle based on the WUS signal. For a terminal that adapts to the second indication information, after detecting DCI, it acquires the second indication information and enters continuous sleep and / or continuous wake-up according to the DRX cycle sleep and wake-up information.

[0101] In some embodiments, the DRX cycle sleep-wake information in the second indication information includes: the number of DRX cycles or the number of DRX cycle units for continuous sleep or continuous wake-up, wherein one DRX cycle unit includes a preset number of DRX cycles; in response to the indication information corresponding to the terminal being the second indication information, performing sleep or wake-up operations for multiple consecutive DRX cycles according to the DRX cycle sleep-wake information includes: performing the corresponding sleep-wake operation within multiple consecutive DRX cycles according to the number of DRX cycles or the number of DRX cycle units for continuous sleep or continuous wake-up.

[0102] In this embodiment, the DRX cycle sleep / wake information indicates the number of consecutive wake-up or consecutive sleep cycles. The terminal performs sleep or wake-up operations for multiple consecutive cycles based on this number. In an example where the DRX cycle sleep / wake information includes the number of consecutive sleep or wake-up DRX cycles, for example, if the DRX cycle number = 4 and Wakeup Ind = 0, the terminal can sleep for 4 consecutive DRX cycles and wake up before the 5th cycle to re-listen to WUS. As another example, if the DRX cycle number = 3 and Wakeup Ind = 1, the terminal can wake up for 3 consecutive DRX cycles, but does not need to listen to WUS for those 3 cycles, and only re-listens to WUS before the 4th cycle. Therefore, both methods reduce the number of WUS listening cycles, thereby reducing power consumption and achieving power saving. In an example where the DRX cycle sleep / wake information includes the number of DRX cycle units for continuous sleep or continuous wake-up, for instance, if the number of DRX cycle units is 3, and one DRX cycle unit = 2 DRX cycles, then the current number of DRX cycles = 6. The terminal can perform continuous sleep or continuous wake-up operations according to 6 DRX cycles. This expands the number of DRX cycles indicated by the fixed-length DCIFormat2-6 instruction, while reducing the number of WUS listening times of the terminal, thereby reducing power consumption and achieving the purpose of power saving.

[0103] In some embodiments, the DRX cycle sleep-wake information in the second indication information includes: a sleep-wake mode identifier, which corresponds to a pre-configured DRX cycle sleep-wake mode; in response to the terminal's corresponding indication information being the second indication information, performing sleep or wake-up operations for multiple consecutive DRX cycles according to the DRX cycle sleep-wake information includes: obtaining the corresponding DRX cycle sleep-wake mode according to the sleep-wake mode identifier; and performing the corresponding sleep-wake operation within multiple consecutive DRX cycles according to the DRX cycle sleep-wake mode. In this embodiment, the network-side device pre-sends the pre-configured DRX cycle sleep-wake mode corresponding to the sleep-wake mode identifier to the terminal for storage, so that after the terminal obtains the sleep-wake mode identifier in the second indication information from the DCI, it can query the corresponding DRX cycle sleep-wake mode locally and perform continuous sleep or continuous wake-up operations according to the DRX cycle sleep-wake mode indication.

[0104] In some embodiments, the DRX cycle sleep-wake mode includes: waking up continuously for N DRX cycles followed by sleeping continuously for M DRX cycles, or sleeping continuously for N DRX cycles followed by waking up continuously for M DRX cycles, where N and M are positive integers. For example, if N=5 and M=3, the terminal can sleep continuously for 5 DRX cycles and then wake up continuously for 3 DRX cycles. During these 8 consecutive cycles, it does not need to listen to WUS, and wakes up before the 9th cycle to listen to WUS again. This reduces the number of WUS listening cycles, thereby reducing power consumption and achieving power saving.

[0105] In some embodiments, the method provided in this application further includes: not listening to DCI during multiple DRX cycles in which sleep or wake-up operations are performed for multiple consecutive DRX cycles based on DRX cycle sleep-wake information. In some embodiments, after performing sleep or wake-up operations for multiple consecutive DRX cycles based on DRX cycle sleep-wake information, the method provided in this application further includes: re-listening to DCI before the start of the next DRX cycle, obtaining new second indication information, and performing sleep-wake operations in DRX cycle mode according to the new second indication information. In this embodiment, the terminal does not need to listen to WUS during multiple DRX cycles in which sleep or wake-up operations are performed for multiple consecutive DRX cycles, but only wakes up before the start of the next DRX cycle to re-listen to WUS. Thus, the number of WUS listening times can be reduced, thereby reducing power consumption and achieving power saving. At the same time, it can also ensure that data transmission does not cause delay. After re-listening to WUS and obtaining new second indication information, such as updating the number of consecutive sleep or wake-up DRX cycles, the sleep or wake-up operation is performed according to the updated number of DRX cycles.

[0106] The information transmission method provided in this application embodiment enables two different power-saving control mechanisms within the same DCI using indication information from different types of terminals, simultaneously supporting terminals with different capabilities and power consumption requirements. The first indication information is compatible with the prior art where WUS monitoring is required before each DRX cycle to perform sleep or wake-up operations for that DRX cycle. The second indication information allows terminals with different service transmission needs and high power-saving requirements to reduce the number of WUS monitoring cycles, enabling continuous sleep or wake-up for multiple DRX cycles, significantly reducing terminal monitoring frequency and power consumption, resulting in noticeable power savings for the terminal.

[0107] Below, we will combine an application example and... Figure 9 , Figure 10 This paper explains and clarifies the sleep-wake behavior and power consumption distribution of a terminal in DRX cycle mode under continuous data burst scenarios.

[0108] Figure 9 The diagram illustrates the sleep-wake behavior and power consumption distribution of a UE after detecting WUS in a continuous data burst scenario, according to relevant technologies. Figure 10 The illustration shows the sleep-wake behavior and power consumption distribution of the UE after detecting WUS in a continuous data burst scenario in the embodiments of this application.

[0109] Taking the example of data bursts being transmitted for three consecutive DRX cycles. Figure 9 As shown, in related technologies, a fixed wake-up is performed before each DRX cycle. After waking up, pre-synchronization is first completed based on the SSB, and then the WUS is detected. In continuous data burst scenarios, the WUS signal detection is 1 before each DRX cycle, and DRX On is turned on accordingly for each DRX cycle. After completing the data burst service transmission, it enters deep sleep again. The gap between the SSB and WUS used for pre-synchronization, and between WUS and DRX On, is approximately at the slot level. Depending on the UE power-saving handover time limit, it may only be able to enter micro sleep and cannot enter a deeper level of light sleep or deep sleep. Figure 10As shown in the embodiment of this application, the UE wakes up before the first DRX cycle. After waking up, it first completes pre-synchronization based on SSB, and then detects WUS. In the continuous data burst scenario, DCI 2-6 indicates WUS=1, and the number of consecutive wake-up DRX cycles is 3. Accordingly, after receiving the WUS signal before the first DRX cycle, the UE knows in advance that it will wake up in the next 3 DRX cycles to complete data transmission during the DRX On wake-up period. Therefore, starting from the second DRX cycle, it does not need to detect DCI 2-6 to obtain WUS indication information for the next two consecutive DRX cycles; it only needs to wake up in advance periodically to perform SSB pre-synchronization and then turn on DRX ON. Figure 10 As can be seen, only SSB-based pre-synchronization needs to be completed before the second and third DRX cycles, shortening the early wake-up time and correspondingly increasing the deep sleep time. Even if the SSB position used for pre-synchronization remains unchanged after reducing WUS detection, more time (1 ms to 20 ms level) is provided between the SSB and DRX On due to the removal of WUS monitoring, allowing the UE to enter a more power-saving sleep state. Therefore, the technical solution provided in this application embodiment still brings power-saving gains.

[0110] Below, we will combine an application example and... Figure 11 , Figure 12 This paper explains and clarifies the sleep-wake behavior and power consumption distribution of a terminal in DRX cycle mode under continuous no-data-burst scenarios.

[0111] Figure 11 The diagram illustrates the sleep-wake behavior and power consumption distribution of a UE after detecting a WUS (Wide-Ended System) in a continuous no-data-burst scenario, according to relevant technologies. Figure 12 The illustration shows the sleep-wake behavior and power consumption distribution of the UE after detecting WUS in a continuous no-data-burst scenario in the embodiments of this application.

[0112] Let's take an example where no data transmission is required for three consecutive DRX cycles. Figure 11 As shown, in related technologies, a fixed wake-up is performed before each DRX cycle. After waking up, pre-synchronization is first completed based on SSB, and then WUS is detected. In scenarios with continuous no data bursts, the WUS signal detection before each DRX cycle is 0. Accordingly, DRX On in each DRX cycle does not enable reception; only SSB pre-synchronization and WUS reception are completed before entering deep sleep. Figure 12As shown in the embodiment of this application, the UE wakes up before the first DRX cycle. After waking up, it first completes pre-synchronization based on SSB, and then detects WUS. In the scenario of continuous no data bursts, DCI 2-6 indicates WUS=0, and the number of consecutive DRX cycles without bursts is 3. Accordingly, after receiving the WUS signal before the first DRX cycle, the UE knows in advance that it does not need to wake up for data transmission during DRX Onduration in the next 3 DRX cycles. Therefore, it does not need to detect DCI2-6 to obtain WUS indication information for the next three consecutive DRX cycles starting from the first DRX cycle, and can remain in deep sleep until the fourth DRX cycle before waking up for pre-synchronization and receiving the WUS signal. Figure 12 As can be seen, compared with the technical solutions in related technologies, the technical solution provided in this application reduces the wake-up pre-synchronization and WUS reception in each DRX cycle, and maintains deep sleep for three consecutive DRX cycles, achieving a longer period of deep sleep, thereby bringing better power saving effect.

[0113] Below, taking the calculation of the total sleep duration and power saving of continuous wake-up and continuous sleep within 8 and 16 consecutive DRX cycles as examples, we compare the existing technical solution (i.e., wake-up detection WUS in each cycle) with the energy-saving solution provided by the embodiments of this application (continuous wake-up or continuous sleep based on DRX cycle sleep wake-up information in the second indication information).

[0114] Taking an SSB signal reception and processing time of 5ms, a WUS signal listening time of 10ms, and a DRX On duration of 10ms per DRX cycle as examples, a DRX cycle is set to 40ms, 80ms, and 160ms respectively. Table 1 shows a comparison of the achievable sleep duration and power saving of the UE in continuous wake-up scenarios within 8 consecutive DRX cycles and 16 consecutive DRX cycles, using the prior art solution and the technical solution of this application. See Table 1. Table 2 shows a comparison of the achievable sleep duration and power saving of the UE in continuous sleep scenarios within 8 consecutive DRX cycles and 16 consecutive DRX cycles, using the prior art solution and the technical solution of this application. See Table 2.

[0115] Table 1.

[0116]

[0117] Table 2.

[0118]

[0119] As shown in Tables 1 and 2, regardless of whether the UE is in a fixed wake-up or fixed sleep scenario, in the embodiments of this application, the sleep duration that the UE can achieve within 8 consecutive DRX cycles and 16 consecutive DRX cycles is longer than that of the prior art, which greatly saves UE power consumption. In the embodiments of this application, after receiving the WUS signal in the first DRX cycle, the number of DRX cycles that can be continuously woken up or continuously sleep is obtained as 8 or 16, thereby reducing the power consumption overhead of WUS signal listening and the resulting power-saving wake-up pre-synchronization processing in the subsequent 7 or 15 DRX cycles, thus achieving better power-saving performance. The more DRX cycles that indicate continuous wake-up or sleep with a single WUS signal, the more energy can be saved; the smaller each DRX cycle, the greater the energy saved by saving WUS signal listening; under the same conditions, continuous sleep of the UE can achieve better power-saving performance than continuous wake-up of the UE.

[0120] Based on the above data analysis, compared with existing power-saving control solutions using WUS during DRX cycles, the information transmission scheme provided in this application has the following significant technical advantages: it reduces the number of WUS signal monitoring attempts and power consumption overhead; it is compatible with the power-saving control needs of various types of terminals, including ordinary NR terminals, RedCap UE terminals, and other 5G industrial IoT terminals; it is compatible with the data burst requirements of different service scenarios while meeting power-saving needs; and it achieves more precise power-saving control, resulting in better power-saving performance for the UE. This application is applicable to all NR terminals, especially RedCap UEs and other UEs that do not support multi-carrier and secondary cell sleep modes, achieving a balance between precise power-saving control and low data transmission latency, significantly improving the power-saving performance of the terminal during DRX cycles compared to the original scheme.

[0123] In some embodiments, the terminal type corresponding to the first indication information is a terminal that supports secondary cell sleep function, and the terminal type corresponding to the second indication information is a terminal that does not support secondary cell sleep function.

[0124] In some embodiments, DCI is DCI Format 2-6, and the first indication information and the second indication information are mutually independent information unit blocks in DCI Format 2-6.

[0129] (3) Sleep wake-up mode identifier, wherein the sleep wake-up mode identifier corresponds to the pre-configured DRX periodic sleep wake-up mode, so as to instruct the corresponding type of terminal to obtain the corresponding DRX periodic sleep wake-up mode according to the sleep wake-up mode identifier to enter continuous sleep or continuous wake-up.

[0130] In some embodiments, the DRX cycle sleep-wake mode includes: waking up continuously for N DRX cycles followed by continuous sleep for M DRX cycles, or sleeping continuously for N DRX cycles followed by continuous wake-up for M DRX cycles, where N and M are positive integers.

[0131] In some embodiments, such as Figure 14As shown, the information transmission device 100 provided in this application embodiment further includes: a configuration module 102, configured to determine indication information corresponding to the terminal according to the type of the terminal; and a sending module 101, further configured to send a first message to the terminal, wherein the first message includes: resource location information of the indication information corresponding to the terminal in the DCI. In some embodiments, the resource location information includes the start bit of the indication information corresponding to the terminal in the DCI, or the resource location information includes the start bit and the length of the indication information.

[0132] In some embodiments, the configuration module 102 determines the indication information corresponding to the terminal based on the terminal type in the following manner: when the terminal type adapts to the second indication information, it determines the second indication information corresponding to terminals with different service transmission requirements based on the terminal's service transmission requirements. The resource location information of the terminal-corresponding indication information in the DCI in the first message includes the resource location information of the second indication information corresponding to terminals with different service transmission requirements in the DCI. In this embodiment, the resource location information of the second indication information can also be sent to the terminal in advance via the first message, so that the terminal can obtain the corresponding second indication information from the DCI.

[0133] The information transmission device provided in this application embodiment enables two different power-saving control mechanisms within the same DCI through indication information from different types of terminals, simultaneously supporting terminals with different capabilities and power consumption requirements. The first indication information is compatible with the prior art where WUS monitoring is required before each DRX cycle to perform sleep or wake-up operations for that DRX cycle. The second indication information allows terminals with different service transmission needs and high power-saving requirements to reduce the number of WUS monitoring sessions, enabling continuous sleep or wake-up for multiple DRX cycles, significantly reducing terminal monitoring frequency and power consumption, resulting in noticeable power savings for the terminal.

[0134] An exemplary embodiment of this application also provides an information transmission device 200 applied to a terminal. Figure 15 This illustration shows a structural block diagram of an information transmission device 200 applied to a terminal according to an exemplary embodiment of this application.

The embodiment of the information transmission device 200 applied to the terminal corresponds to the above-described information transmission method embodiment. All implementation processes and methods of the above-described method embodiment can be applied to the embodiment of the information transmission device 200 applied to the terminal, and can achieve the same technical effect.

[0135] like Figure 15 As shown, the information transmission device 200 includes:

[0136] The receiving module 201 is used to acquire downlink control information (DCI); wherein, the DCI includes first indication information and second indication information; the first indication information and the second indication information are adapted to different types of terminals respectively; the first indication information includes single sleep wake-up information to indicate that the corresponding type of terminal sleeps or wakes up in the current DRX cycle; the second indication information includes DRX cycle sleep wake-up information to indicate that the corresponding type of terminal enters continuous sleep and / or continuous wake-up according to the DRX cycle sleep wake-up information.

[0137] The acquisition module 202 is used to acquire the indication information corresponding to the terminal from the DCI;

[0138] The execution module 203 is used to perform a sleep wake-up operation in the discontinuous reception DRX cycle mode according to the instruction information corresponding to the terminal.

[0139] In some embodiments, the receiving module 201 is further configured to receive a first message before acquiring the downlink DCI, the first message including resource location information of the indication information corresponding to the terminal in the DCI.

[0142] The first indication information is the indication information corresponding to the terminal. The sleep or wake-up operation of this DRX cycle is performed according to the single sleep wake-up information.

[0143] In response to the terminal's corresponding indication information, which is the second indication information, sleep or wake-up operations for multiple consecutive DRX cycles are performed based on the DRX cycle sleep-wake information.

[0144] In some embodiments, the DRX cycle sleep-wake information in the second indication information includes: the number of DRX cycles or the number of DRX cycle units for continuous sleep or continuous wake-up, wherein one DRX cycle unit includes a preset number of DRX cycles; the execution module 203 responds to the indication information corresponding to the terminal as the second indication information in the following manner, and performs sleep or wake-up operations for multiple consecutive DRX cycles according to the DRX cycle sleep-wake information: performs the corresponding sleep-wake operation within multiple consecutive DRX cycles according to the number of DRX cycles or the number of DRX cycle units for continuous sleep or continuous wake-up.

[0145] In some embodiments, the DRX cycle sleep-wake information in the second indication information includes: a sleep-wake mode identifier, which corresponds to a pre-configured DRX cycle sleep-wake mode; the execution module 203 responds to the indication information corresponding to the terminal as the second indication information in the following manner, and performs sleep or wake-up operations for multiple consecutive DRX cycles according to the DRX cycle sleep-wake information: obtains the corresponding DRX cycle sleep-wake mode according to the sleep-wake mode identifier; and performs the corresponding sleep-wake operation in multiple consecutive DRX cycles according to the DRX cycle sleep-wake mode.

[0146] In some embodiments, the DRX cycle sleep-wake mode includes: waking up continuously for N DRX cycles followed by continuous sleep for M DRX cycles, or sleeping continuously for N DRX cycles followed by continuous wake-up for M DRX cycles, where N and M are positive integers.

[0147] In some embodiments, the receiving module 201 does not listen to DCI during multiple DRX cycles in which the execution module 203 performs sleep or wake-up operations for multiple consecutive DRX cycles based on the DRX cycle sleep wake-up information.

[0148] In some embodiments, the receiving module 201 is further configured to re-listen to the DCI before the start of the next DRX cycle after the execution module 203 performs sleep or wake-up operations for multiple consecutive DRX cycles based on the DRX cycle sleep wake-up information; the obtaining module 202 is further configured to obtain new second indication information, and the execution module 203 is further configured to perform sleep wake-up operations in the DRX cycle mode based on the new second indication information.

[0149] The information transmission device provided in this application embodiment enables two different power-saving control mechanisms within the same DCI through indication information from different types of terminals, simultaneously supporting terminals with different capabilities and power consumption requirements. The first indication information is compatible with the prior art where WUS monitoring is required before each DRX cycle to perform sleep or wake-up operations for that DRX cycle. The second indication information allows terminals with different service transmission needs and high power-saving requirements to reduce the number of WUS monitoring sessions, enabling continuous sleep or wake-up for multiple DRX cycles, significantly reducing terminal monitoring frequency and power consumption, resulting in noticeable power savings for the terminal.
