[0070] In this application, the communication device used to implement the terminal function can be a terminal, or a terminal with some of the functions of the above terminal, or a device that can support the implementation of the functions of the above terminal, such as a chip system, which can be installed in the terminal or used in conjunction with the terminal. In this application, the chip system can be composed of a chip, or it can include a chip and other discrete devices. In the technical solution provided in this application, the communication device is described as a terminal or UE as an example.

[0071] Optionally, a wireless communication system is typically composed of cells, and network equipment provides cell management and communication services to multiple mobile stations (MS) in the cell. The network equipment includes a baseband unit (BBU) and a remote radio unit (RRU). The BBU and RRU can be placed in different locations, for example: the RRU is remote and placed in an area with high traffic volume, while the BBU is placed in a central computer room. The BBU and RRU can also be placed in the same computer room. The BBU and RRU can also be different components under the same rack. Optionally, a cell can correspond to a carrier or component carrier.

[0072] In some deployments, the network devices mentioned in the embodiments of the present application may include a CU, a DU, or both a CU and a DU, or a control plane CU node (central unit-control plane (CU-CP)), a user plane CU node (central unit-user plane (CU-UP)), and a DU node. For example, the network devices may include a gNB-CU-CP, a gNB-CU-UP, and a gNB-DU.

[0073] Optionally, in an embodiment of the present application, a terminal or network device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a Windows operating system. The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. In addition, the embodiment of the present application does not specifically limit the specific structure of the execution subject of the method provided in the embodiment of the present application. It can communicate according to the method provided in the embodiment of the present application by running a program that records the code of the method provided in the embodiment of the present application. For example, the execution subject of the method provided in the embodiment of the present application can be a terminal or network device, or a functional module in a terminal or network device that can call and execute a program.

[0074] In other words, the relevant functions of the terminal or network device in the embodiments of the present application can be implemented by a single device, or by multiple devices together, or by one or more functional modules within a single device, and the embodiments of the present application do not specifically limit this. It is understood that the above functions can be network elements in hardware devices, software functions running on dedicated hardware, or a combination of hardware and software, or virtualized functions instantiated on a platform (e.g., a cloud platform).

[0075] The communication between the network device and the terminal follows a certain protocol layer structure. The protocol layer structure may include a control plane protocol layer structure and a user plane protocol layer structure. For example, the control plane protocol layer structure may include the functions of the radio resource control (RRC) layer, the packet data convergence protocol (PDCP) layer, the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical layer. For example, the user plane protocol layer structure may include the functions of the PDCP layer, the RLC layer, the MAC layer, and the physical layer. In one possible implementation, a service data adaptation protocol (SDAP) layer may also be included above the PDCP layer.

[0076] Optionally, the protocol layer structure between the network device and the terminal may also include an artificial intelligence (AI) layer for transmitting data related to AI functions.

[0077] Taking data transmission between network devices and terminals as an example, data transmission needs to pass through the user plane protocol layers, such as the SDAP layer, PDCP layer, RLC layer, MAC layer, and physical layer. The SDAP layer, PDCP layer, RLC layer, MAC layer, and physical layer can also be collectively referred to as the access layer. Data transmission is divided into sending or receiving based on the direction of transmission, and each of these layers is further divided into a sending part and a receiving part. Taking downlink data transmission as an example, after the PDCP layer obtains data from the upper layer, it transmits the data to the RLC layer and MAC layer. The MAC layer then generates a transport block, which is then wirelessly transmitted through the physical layer. Data is encapsulated accordingly in each layer. For example, data received by a layer from the layer above it is considered a service data unit (SDU) of that layer. After encapsulation by that layer, it becomes a protocol data unit (PDU) and is then passed to the next layer.

[0078] For example, a terminal may also have an application layer and a non-access layer. The application layer can be used to provide services to applications installed in the terminal. For example, downlink data received by the terminal can be sequentially transmitted from the physical layer to the application layer, and then provided to the application by the application layer. For another example, the application layer can obtain data generated by the application and sequentially transmit the data to the physical layer for transmission to other communication devices. The non-access layer can be used to forward user data, such as forwarding uplink data received from the application layer to the SDAP layer, or forwarding downlink data received from the SDAP layer to the application layer.

[0079] It should be understood that the number and type of each device in the communication system shown in Figures 1A and 1B are for illustration only, and the present application is not limited to this. In actual applications, the communication system may also include more terminals, more access network devices, and other network elements, such as core network devices, and / or network elements for implementing artificial intelligence functions.

[0080] It is understandable that all or part of the functions implemented by one or more of the terminals, access network devices, core network devices, or network elements for implementing artificial intelligence functions can be virtualized, that is, implemented by one or more of the proprietary processors or general-purpose processors and the corresponding software modules. Among them, since the terminal and the access network device involve an interface for air interface transmission, the transceiver function of the interface can be implemented by hardware. Core network equipment, such as operation administration and maintenance (OAM) network elements, can be virtualized. Optionally, one or more functions of the virtualized terminal, access network device, core network device, or network elements for implementing artificial intelligence functions can be implemented by cloud devices, such as cloud devices in an over the top (OTT) system.

[0081] The communication between the network device and the terminal in the communication system shown in Figures 1A and 1B can also be represented in another form. As shown in Figure 2, terminal 10 includes a processor 101, a memory 102, and a transceiver 103. Transceiver 103 includes a transmitter 1031, a receiver 1032, and an antenna 1033. Network device 20 includes a processor 201, a memory 202, and a transceiver 203. Transceiver 203 includes a transmitter 2031, a receiver 2032, and an antenna 2033. Receiver 1032 can be configured to receive transmission control information via antenna 1033, and transmitter 1031 can be configured to send transmission feedback information to network device 20 via antenna 1033. Transmitter 2031 can be configured to send transmission control information to terminal 10 via antenna 2033, and receiver 2032 can be configured to receive transmission feedback information sent by terminal 10 via antenna 2033.

[0082] The processor 101 / processor 201 may be a CPU, a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the present application.

[0083] The memory 102 / memory 202 may be a device having a storage function. For example, it may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, an optical disc storage (including a compact disc, laser disc, optical disc, digital versatile disc, Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory may exist independently and be connected to the processor via a communication line. The memory may also be integrated with the processor.

[0084] Among them, the memory 102 / memory 202 is used to store computer-executable instructions for executing the solution of the present application, and the execution is controlled by the processor 101 / processor 201. The processor 101 / processor 201 is used to execute the computer-executable instructions stored in the memory 102 / memory 202, thereby implementing the synchronization signal block transmission method provided in the embodiment of the present application.

[0085] Alternatively, in an embodiment of the present application, the processor 101 / processor 201 may also perform processing-related functions in the synchronization signal block transmission method provided in the following embodiments of the present application.

[0086] The computer-executable instructions in the embodiments of the present application may also be referred to as application code, which is not specifically limited in the embodiments of the present application.

[0087] As shown in FIG3 , which is a schematic diagram of an analysis of operator costs according to an example embodiment of the present application, according to a report by the Global System for Mobile Communications Association (GSMA), the energy cost of a mobile network accounts for approximately 23% of an operator's total costs (of which selling, general, and administrative (SG&A) and others account for approximately 75%, and other network operating costs account for approximately 2%).

[0088] Furthermore, as shown in Figure 4, which is an analysis diagram of the energy consumption of a wireless network according to an embodiment of the present application, most of the energy cost of the mobile network comes from the wireless access network, especially the AAU and BBU, while the data center and optical fiber transmission account for a smaller share.

[0089] Therefore, the Third Generation Partnership Project (3 rd The 3GPP (3rd Generation Partnership Project) Release 18 (Revision 18) established the Network Energy Saving (NES) project, aiming to research methods for reducing network energy consumption. The existing 3GPP New Radio (NR) protocol defaults to a 20ms SSB period for idle terminals; this can be reconfigured in the RRC protocol for active terminals. Consequently, cells with accessible terminals can only transmit at 20ms intervals (SSB transmissions occupy certain time domain resources, and cells cannot sleep), resulting in network equipment being unable to save power during these time domains.

[0090] To this end, the present application provides a synchronization signal block transmission scheme, in which the network device instructs the terminal on the number of beams that transmit synchronization signal blocks within one cycle. The cycle of the synchronization signal block is N / M times the existing cycle. The terminal receives the synchronization signal block according to the instruction of the network device, so that the network device can reasonably transmit the synchronization signal block, saving power consumption of both communicating parties.

[0091] Based on the above communication system, the synchronization signal block transmission method provided by this application is described below:

[0092] As shown in Figure 5, a flowchart of a synchronization signal block transmission method provided in an embodiment of the present application is provided. Exemplarily, the method may include the following steps:

[0093] S501: A network device sends first indication information to a terminal. Correspondingly, the terminal receives the first indication information.

[0094] In existing technologies, a network device can send SSBs to a terminal over N beams within a period (e.g., 20ms), with each beam having a period of 20ms. SSB transmission occupies a certain amount of time domain resources, which prevents the network device from going into sleep mode and thus fails to save power.

[0095] In this embodiment, the network device can still be configured with N beams within a cycle. However, the network device can indicate that the number of beams transmitting SSBs within a cycle is M, and the period of the SSB is N / M times the configured period. In other words, the network device can instruct the terminal to transmit SSBs on only M beams within a cycle, and the period of these M beams is N / M times the configured period. Where N is greater than or equal to M, and both N and M are positive integers. By transmitting SSBs on only M beams within a cycle, power consumption of the communication device can be reduced.

[0096] For example, the network device sends first indication information to the terminal, wherein the first indication information is used to indicate the number M of beams transmitting synchronization signal blocks within a cycle.

[0097] Alternatively, the number M of beams transmitting SSBs in one period may also be predefined by the protocol.

[0098] For example, a network device can indicate the number of SSBs to be transmitted within a period, M = N / 2, N / 4, or N / 8. N is the total number of beams configured to transmit SSBs within a period. For example, in the sub3G-6G band, N = 8; and below sub3G, N = 4. Assuming a configured period of 20ms and N = 8, when M = N / 2, the period of each SSB is 40ms; when M = N / 4, the period of each SSB is 80ms; and when M = N / 8, the period of each SSB is 160ms.

[0099] As shown in Figure 6, a schematic diagram of setting the period of a synchronization signal block is shown in an example of an embodiment of the present application. A configured period is 20ms, 8 beams are configured within a period, and the first indication information indicates that the number of beams transmitting SSBs within a period is M = 4, so the period of each SSB is 40ms. Figure 6 illustrates SSB1 and SSB2 transmitted on two beams, with a transmission period of 40ms. SSB1 is transmitted on beam 1 in the first period, and SSB2 is transmitted on beam 2 in the second period.

[0100] The SSBs on different beams are sent in a time division manner, that is, the SSBs on different beams are sent at different time domain positions.

[0101] Exemplarily, the first indication information may be carried in any one of the following signaling: SIB, RRC signaling, MAC-CE, DCI. The SIB, RRC signaling, MAC-CE, DCI may be obtained from the current carrier or from other carriers.

[0102] For example, the first indication information may be represented by the ssb-PositionInBurst field in the SIB1. The ssb-PositionInBurst field includes a bitmap. However, for older users (e.g., the 3GPP (3 rd For users of 3GPP (3rd Generation Partnership Project) revision 18 and earlier, the number of bits in this bitmap is equal to the total number of beams. Each bit in this bitmap indicates whether an SSB is transmitted on the corresponding beam. In this embodiment, M bits are added to the synchronization signal block-burst position in the SIB. This first indication information is used to indicate the number M of beams transmitting synchronization signal blocks within a period.

[0103] For another example, M bits may be added to RRC signaling, MAC-CE or DCI to indicate the number M of beams transmitting SSBs in one period.

[0104] By configuring the period of each beam so that not every beam sends SSB in every period, power consumption of both communicating parties can be saved.

[0105] Furthermore, in some communication scenarios, SSBs need to be sent with a shorter period to ensure basic coverage. Assuming SSBs are transmitted on multiple beams, the period of the first beam can be configured to be the preset first period. For example, in the central area, where there is no overlap with other cells, cells in the central area can transmit SSB1 with a shorter period. For example, the period of one beam can still be 20ms.

[0106] Among the multiple beams, the period of at least one second beam other than the first beam is configurable. The periods of different beams in at least one second beam can be the same or different. For example, the period of at least one second beam can be configured to be 40ms, 80ms or 160ms through SIB, RRC signaling, MAC-CE or DCI. The above-mentioned SIB, RRC signaling, MAC-CE or DCI can be obtained from this carrier; it can also be obtained from other carriers. For example, an N2 bit can be added to RRC signaling, MAC-CE or DCI to indicate the period of at least one second beam. Wherein, N2 is a positive integer.

[0107] As shown in Figure 7, it is a schematic diagram of setting the period of another synchronization signal block of an example embodiment of the present application. The period of SSB1 predefined by the protocol or configured by the network device is 20ms; the period of SSB1 predefined by the protocol or configured by the network device is 40ms, 80ms or 160ms.

[0108] The period of the first beam is predefined by the protocol or configured by the network device to be a preset first period, such as 20ms, while the periods of the remaining beams are greater than 20ms. While ensuring basic communication, power consumption of both communicating parties can be saved.

[0109] S502: The network device sends a synchronization signal block to the terminal according to the first instruction information. Correspondingly, the terminal receives the synchronization signal block.

[0110] After the network device sends the first indication information to the terminal, it sends the SSB to the terminal according to the first indication information. That is, the network device sends the SSB to the terminal at the beam period indicated by the first indication information. Similarly, the terminal receives the SSB on the corresponding beam according to the first indication information and at the beam period indicated by the first indication information.

[0111] According to a synchronization signal block transmission method provided in an embodiment of the present application, the network device instructs the terminal on the number of beams that transmit synchronization signal blocks within one cycle, and the cycle of the synchronization signal block is N / M times the existing cycle. The terminal receives the synchronization signal block according to the instruction of the network device, so that the network device can reasonably transmit the synchronization signal block, thereby saving power consumption of both communicating parties.

[0112] As shown in Figure 8, a flowchart of another synchronization signal block transmission method provided in an embodiment of the present application is provided. Exemplarily, the method may include the following steps:

[0113] S801. The network device sends SIB1 to the terminal. Correspondingly, the terminal receives SIB1.

[0114] SIB1 includes an ssb-PositionInBurst field, which includes a bitmap.

[0115] Among them, for the first terminal, the bit map is used to indicate whether SSB is transmitted on the first beam in the first period; here, the first terminal can be an old user, such as a user of R18 and earlier. For users of R18 and earlier, when they receive SIB1, they still parse the bit map according to the existing understanding. For example, 8 beams are configured in one period, and the bit map is 8 bits. For example, if the value of the bit map is "10000000", it means that SSB is transmitted on the first beam, and SSB is not transmitted on the other 7 beams; for another example, if the value of the bit map is "01000000", it means that SSB is transmitted on the second beam, and SSB is not transmitted on the other 7 beams. The period of the first beam can be a preset period, such as 20ms.

[0116] For the second terminal, different values ​​of the bitmap are used to indicate different transmission periods of synchronization signal blocks. Here, the second terminal can be a new user, such as a user of 3GPP version 19 (revision 19, R19), or a user after R19. Here, the user of R19 is taken as an example. For users of R19 and later, when they receive SIB1, they parse the different values ​​of the bitmap to indicate different transmission periods of SSB. For example, if the value of the bitmap is "10000000", it means that the transmission period of SSB transmitted on one or more second beams (the number of second beams here can be pre-negotiated or predefined by the protocol) is 40ms; for another example, if the value of the bitmap is "01000000", it means that the transmission period of SSB transmitted on one or more second beams is 80ms. That is, different values ​​of the bitmap are used to indicate different transmission periods.

[0117] Furthermore, for the second terminal, different values ​​of the bitmap can also be used to indicate the number of second beams carrying SSBs. For example, the relationship between the value of the bitmap and the SSB transmission period and the identifier of the beam transmitting SSB is shown in Table 1 below:

[0118] Table 1

[0119] The period of at least one second beam is configurable. The periods of different beams in at least one second beam may be the same or different. For example, the period of at least one second beam may be configured to be 40ms, 80ms or 160ms through SIB, RRC signaling, MAC-CE or DCI. The above-mentioned SIB, RRC signaling, MAC-CE or DCI may be obtained from this carrier; or may be obtained from other carriers. For example, an N2 bit may be added to RRC signaling, MAC-CE or DCI to indicate the period of at least one second beam. Wherein, N2 is a positive integer.

[0120] Furthermore, the synchronization signal blocks transmitted by the network device to the first terminal on one or more first beams and the synchronization signal blocks transmitted by the network device to the second terminal on one or more second beams can be time-division multiplexing (TDM), that is, the SSBs transmitted on one or more first beams and the SSBs transmitted on one or more second beams are located at different time domain positions; or the synchronization signal blocks transmitted by the network device to the first terminal on one or more first beams and the synchronization signal blocks transmitted by the network device to the second terminal on one or more second beams can be frequency-division multiplexing (FDM), that is, the SSBs transmitted on one or more first beams and the SSBs transmitted on one or more second beams are located at different frequency domain positions.

[0121] S802. The network device sends an SSB to the terminal according to SIB1. Correspondingly, the terminal receives the SSB according to SIB1.

[0122] The network device sends SIB1 and sends SSB according to the SIB1.

[0123] The terminal receives SIB1 and receives SSB according to SIB1. The terminal may be the first terminal or the second terminal.

[0124] According to a synchronization signal block transmission method provided by an embodiment of the present application, a network device transmits SIB1, which includes a synchronization signal block-burst position field. The synchronization signal block-burst position field includes a bitmap. For a first terminal, the bitmap is used to indicate whether a synchronization signal block is transmitted on multiple first beams within a first period. For a second terminal, different values ​​of the bitmap are used to indicate different synchronization signal block transmission periods. After receiving SIB1, the first terminal / second terminal receives the synchronization signal block based on SIB1. This achieves compatibility between new and old terminals, allowing terminals to accurately receive synchronization signal blocks.

[0125] In this application, "sending information to... (e.g., a terminal)" or the related illustrations in the accompanying drawings can be understood as the destination end of the information being the terminal. This can include sending information to the terminal directly or indirectly. "Receiving information from... (e.g., a terminal)" or "receiving information from... (e.g., a terminal)", or the related illustrations in the accompanying drawings can be understood as the source end of the information being the terminal, which can include receiving information from the terminal directly or indirectly. The information may be processed as necessary between the source end and the destination end of the information transmission, such as format changes, etc., but the destination end can understand the valid information from the source end. Similar expressions in this application can be understood similarly and will not be repeated here.
