Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a method and apparatus for transmitting information. Background Technology

[0002] In 5G New Radio (NR) systems, terminal devices need to obtain system information from the network when they need to access the network. Specifically, they can obtain some system information through the Physical Broadcast Channel (PBCH, or NR-PBCH) and the Remaining Minimum System Information (RMSI) through the Physical Downlink Shared Channel (PDSCH, or NR-PDSCH). The Downlink Control Information (DCI) corresponding to the NR-PDSCH is carried on the Physical Downlink Control Channel (PDCCH, or NR-PDCCH), and the time-frequency resource location of the NR-PDCCH is indicated by the Control Resource Set (CORESET) information carried by the NR-PBCH. The NR-PBCH can also carry indication information to indicate whether the synchronization signal block (SSblock) corresponding to the NR-PBCH is associated with the RMSI. If the indication information indicates that the SSblock is not associated with the RMSI, the terminal device does not need to receive the corresponding RMSI. However, the terminal device needs to blindly detect other SSblocks to obtain the RMSI, which increases the complexity of the terminal device in detecting SSblocks. Summary of the Invention

[0003] This application provides a method and apparatus for transmitting information, which helps to reduce the complexity of terminal devices detecting SSblocks.

[0004] Firstly, a method for transmitting information is provided, including:

[0005] The terminal device receives a first synchronization signal block sent by the network device. The first synchronization signal block includes a first physical broadcast channel (PBCH). The information carried by the first PBCH includes first information and second information.

[0006] If the first information indicates that there is no remaining minimum system information (RMSI), the terminal device obtains the resource information of the second synchronization signal block from the second information.

[0007] Therefore, in the method of transmitting information in this application embodiment, the terminal device can obtain the resource information of the second synchronization signal block through the second information carried by the first PBCH when the first information carried by the first PBCH indicates that there is no RMSI, and then receive the second synchronization signal block according to the resource information of the second synchronization signal block, thereby reducing the complexity of blind detection of other synchronization signal blocks by the terminal device.

[0008] In conjunction with the first aspect, among some possible implementations of the first aspect, the method further includes:

[0009] The terminal device receives the second synchronization signal block according to the resource information of the second synchronization signal block. The second synchronization signal block includes the second physical broadcast channel PBCH. The information carried by the second PBCH includes third information and fourth information. The third information indicates the existence of RMSI, and the fourth information indicates a resource set carrying control information for receiving RMSI.

[0010] In conjunction with the first aspect, among some possible implementations of the first aspect, the method further includes:

[0011] If the third information indicates the presence of an RMSI, the terminal device obtains the RMSI based on the fourth information.

[0012] In conjunction with the first aspect, in some possible implementations of the first aspect, the terminal device obtains the RMSI based on the fourth information, including:

[0013] Based on the resource set indicated by the fourth information, detect the physical downlink control channel (PDCCH) and obtain the scheduling information of the physical downlink shared channel (PDSCH).

[0014] The RMSI carried in the PDSCH is obtained based on the scheduling information of the PDSCH.

[0015] In conjunction with the first aspect, in some possible implementations of the first aspect, the resource information of the second synchronization signal block is the frequency domain resource location information of the second synchronization signal block or the offset information of the frequency domain location of the second synchronization signal block relative to the first synchronization signal block.

[0016] In conjunction with the first aspect, in some possible implementations of the first aspect, the first bit field used to carry the second information and the second bit field used to carry the fourth information at least partially overlap.

[0017] In other words, when the indication information carried in the PBCH indicates the presence of an RMSI, the second bit field in the PBCH can be used to carry information about the resource set for receiving the control information of the RMSI. When the indication information carried in the PBCH indicates the absence of an RMSI, the fourth information is essentially meaningless. Therefore, it is not necessary to continue using the second bit field to carry the fourth information; instead, some or all of the second bit field can be used to carry the second information. That is, in different scenarios, specific bit fields in the PBCH (i.e., the overlapping part of the first and second bit fields) can be reused to carry different information, thereby reducing signaling overhead.

[0018] In conjunction with the first aspect, in some possible implementations of the first aspect, the RMSI includes at least one of the following:

[0019] Paging configuration parameters, cell selection information, access control information.

[0020] Secondly, a method for transmitting information is provided, including:

[0021] The network device has determined that there is no remaining Minimum System Information (RMSI).

[0022] The network device sends a first synchronization signal block to the terminal device. The first synchronization signal block includes a first physical broadcast channel (PBCH). The information carried by the first PBCH includes first information and second information. The first information is used to indicate that there is no RMSI, and the second information is used to indicate the resource information of the second synchronization signal block.

[0023] In conjunction with the second aspect, in some implementations of the second aspect, the second synchronization signal block includes the second physical broadcast channel PBCH, the information carried by the second PBCH includes third information and fourth information, the third information indicating the presence of RMSI, and the fourth information indicating a resource set carrying control information for receiving RMSI.

[0024] In conjunction with the second aspect, in some implementations of the second aspect, the resource information of the second synchronization signal block is the frequency domain resource location information of the second synchronization signal block or the offset information of the frequency domain location of the second synchronization signal block relative to the first synchronization signal block.

[0025] In conjunction with the second aspect, in some implementations of the second aspect, the first bit field used to carry the second information and the second bit field used to carry the fourth information at least partially overlap.

[0026] In conjunction with the second aspect, in certain implementations of the second aspect, the RMSI includes at least one of the following:

[0027] Paging configuration parameters, cell selection information, access control information.

[0028] Thirdly, an apparatus for transmitting information is provided for performing the method described in the first aspect or any possible implementation thereof. Specifically, the apparatus includes units for performing the method described in the first aspect or any possible implementation thereof.

[0029] Fourthly, an information transmission device is provided, comprising: a memory, a processor, an input interface, and an output interface. The memory, processor, input interface, and output interface are connected via a bus system. The memory stores instructions, and the processor executes the instructions stored in the memory to perform the methods described in the first aspect or any possible implementation thereof.

[0030] Fifthly, an apparatus for transmitting information is provided for performing the method in the second aspect or any possible implementation thereof. Specifically, the apparatus includes units for performing the method in the second aspect or any possible implementation thereof.

[0031] Sixthly, a device for transmitting information is provided, comprising: a memory, a processor, an input interface, and an output interface.

The memory stores instructions, and the processor executes the instructions stored in the memory to perform the methods described in the second aspect or any possible implementation thereof.

[0033] Eighthly, a computer program product including instructions is provided, which, when run on a computer, causes the computer to perform the method of the first aspect or any optional implementation thereof.

[0034] A ninth aspect provides a computer storage medium for storing computer software instructions for performing the methods of the second aspect or any possible implementation thereof, comprising a program designed for performing the aspects.

[0035] In a tenth aspect, a computer program product including instructions is provided, which, when run on a computer, causes the computer to perform the method of the second aspect or any optional implementation thereof. Attached Figure Description

[0043] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0044] The technical solutions of this application embodiment can be applied to various communication systems, such as: Global System of Mobile communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), or future 5G systems, etc.

[0045] Figure 1 This application illustrates a wireless communication system 100 used in an embodiment of this application. The wireless communication system 100 may include a network device 110. The network device 100 may be a device that communicates with terminal devices. The network device 100 can provide communication coverage for a specific geographical area and can communicate with terminal devices (e.g., UEs) located within that coverage area. Optionally, the network device 100 may be a base station (BTS) in a GSM or CDMA system, a base station (NodeB, NB) in a WCDMA system, an evolved Node B (eNB or eNodeB) in an LTE system, or a radio controller in a Cloud Radio Access Network (CRAN). Alternatively, the network device may be a relay station, access point, vehicle-mounted equipment, wearable device, network-side equipment in a future 5G network, or network equipment in a future evolved Public Land Mobile Network (PLMN), etc.

[0046] The wireless communication system 100 also includes at least one terminal device 120 located within the coverage area of ​​the network device 110. The terminal device 120 can be mobile or fixed. Optionally, the terminal device 120 can refer to an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user equipment. The access terminal can be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device, wearable device, terminal device in a future 5G network, or terminal device in a future evolved PLMN, etc.

[0047] It should be noted that in the 5G NR system, PBCH can also be called NR-PBCH, PDCCH can also be called NR-PDCCH, and PDSCH can also be called NR-PDSCH. That is, in the 5G NR system, the above concepts can be used interchangeably.

[0048] In 5G NR systems, common channels (e.g., broadcast channels) and synchronization signals can cover the entire cell through multi-beam scanning, facilitating reception by terminal devices within the cell. Multi-beam transmission of synchronization signals can be achieved using synchronization signal burst sets (SS burst sets). For example, an SS burst set can include one or more SS bursts, and an SS burst can include one or more SS blocks. An SS block can carry one beam of synchronization signal and broadcast channel. For instance, an SS block includes a primary synchronization signal (PSS) of one symbol, a secondary synchronization signal (SSS) of one symbol, and a PBCH of two symbols.

[0049] Specifically, the PBCH can be used to carry CORESET information. CORESET information indicates the set of resources used to receive control information for RMSI. In other words, the CORESET information can be used to determine on which resources the control channel is detected and control information is obtained. For example, CORESET information may include the following information: frequency domain resources, starting Orthogonal Frequency Division Multiplexing (OFDM) symbols and time length, etc.

[0050] The PBCH can also be used to carry indication information, which can indicate whether the SS block is associated with the transmission of RMSI, or in other words, whether an RMSI exists. This indication information can be 1 bit. When an RMSI does not exist, since the terminal device has not obtained the RMSI and is unaware of the resource information of other SS blocks, it needs to blindly check other SS blocks to obtain the RMSI in order to access the network, increasing the terminal device's power consumption and access latency.

[0051] Specifically, the RMSI can be carried by the PDSCH. The terminal device can receive the DCI carried in the PDCCH, obtain the scheduling information of the PDSCH based on the DCI, and then receive the PDSCH through the scheduling information of the PDSCH, thereby obtaining the RMSI. The information of the resource set carrying the PDCCH can be indicated by the CORESET information carried in the PBCH. After obtaining the CORESET information, the terminal device can detect the PDCCH in the resource set indicated by the downlink of the CORESET and obtain the DCI.

[0052] Figure 2 This is a schematic flowchart of a method 200 for transmitting information according to an embodiment of this application. The method 200 can be performed by… Figure 1 The terminal device in the communication system 100 shown performs the following actions: Figure 2 As shown, the method 200 may include the following:

[0053] S210, the terminal device receives a first synchronization signal block sent by the network device. The first synchronization signal block includes a first physical broadcast channel PBCH. The information carried by the first PBCH includes first information and second information.

[0054] S220, if the first information indicates that there is no remaining minimum system information (RMSI), the terminal device obtains the resource information of the second synchronization signal block from the second information.

[0055] Specifically, the terminal device can receive a first synchronization signal block, which may include a first PBCH. Optionally, the first synchronization signal block may also include PSS and SSS, etc. The information carried by the first PBCH may include first information and second information. The first information may be used to indicate whether an RMSI exists. Optionally, if the first information is used to indicate that an RMSI does not exist, the second information may be used to indicate resource information of a second synchronization signal block; or, if the first information is used to indicate that an RMSI exists, the second information may indicate a resource set carrying control information for receiving the RMSI.

[0056] In this embodiment of the application, if the first information indicates that there is no RMSI, the terminal device can obtain the resource information of the second synchronization signal block from the second information carried by the PBCH, and then receive the second synchronization signal block according to the resource information of the second synchronization signal block.

[0057] Therefore, in the method for transmitting information in this application embodiment, the terminal device can obtain the resource information of the second synchronization signal block through the second information carried by the first PBCH when the first information carried by the first PBCH indicates that there is no RMSI. Then, it can receive the second synchronization signal block according to the resource information of the second synchronization signal block. Therefore, the complexity of blind detection of other synchronization signal blocks by the terminal device is reduced, which is beneficial to reducing the power consumption and access latency of the terminal device.

[0058] Optionally, in some embodiments, the method 200 may further include:

[0059] The terminal device receives the second synchronization signal block according to the resource information of the second synchronization signal block. The second synchronization signal block includes the second physical broadcast channel PBCH. The information carried by the second PBCH includes third information and fourth information. The third information indicates the existence of RMSI, and the fourth information indicates a resource set carrying control information for receiving RMSI.

[0060] Specifically, after the terminal device learns the resource information of the second synchronization signal block according to the second information, it can receive the second synchronization signal block at the resource location indicated by the resource information of the second synchronization signal block, and obtain the third and fourth information carried in the second PBCH included in the second synchronization signal block. Furthermore, if the third information indicates that the RMSI exists, the RMSI can be obtained according to the fourth information.

[0061] Optionally, in some embodiments, the terminal device obtains the RMSI based on the fourth information, including:

[0062] Based on the resource set indicated by the fourth information, detect the physical downlink control channel (PDCCH) and obtain the scheduling information of the physical downlink shared channel (PDSCH).

[0063] The RMSI carried in the PDSCH is obtained based on the scheduling information of the PDSCH.

[0064] Specifically, when the third information indicates the presence of an RMSI, the fourth information can indicate the resource set carrying control information for receiving the RMSI. That is, the resource set carrying control information related to the RMSI can be known based on the fourth information. In other words, by detecting the PDCCH on the resource set indicated by the fourth information, the scheduling information of the PDSCH carrying the RMSI can be obtained. Furthermore, the PDSCH can be detected based on the scheduling information of the PDSCH to obtain the RMSI carried in the PDSCH. Then, the network can be accessed based on system information such as the RMSI.

[0065] Therefore, in the method for transmitting information in this application embodiment, the terminal device can obtain the resource information of the second synchronization signal block based on the second information carried by the first PBCH, and then receive the second synchronization signal block based on the resource information of the second synchronization signal block, and obtain the third and fourth information included in the second PBCH. The third information is used to indicate the existence of RMSI, and the fourth information indicates the resource set carrying control information for receiving RMSI. Thus, the terminal device can obtain RMSI based on the fourth information. Therefore, the complexity of blind detection of other synchronization signal blocks by the terminal device is reduced, thereby reducing the power consumption and access latency of the terminal device.

[0066] It should be noted that the terminal device can also obtain resource information of more synchronization signal blocks from the second information. For example, it can obtain resource information of the third synchronization signal block and the fourth synchronization signal block from the second information. This application embodiment only describes the example of obtaining resource information of the second synchronization signal block from the second information, and this application embodiment is not limited thereto.

[0067] It should be understood that, in the embodiments of this application, the first information can be used to indicate whether an RMSI exists, or in other words, the first information can be used to indicate whether a first synchronization signal block is associated with the transmission of an RMSI. Similarly, the third information can also be used to indicate whether an RMSI exists, or in other words, the third information can be used to indicate whether a second synchronization signal block is associated with the transmission of an RMSI. Optionally, the bit fields used to carry the first and third information can be the same bit field. In a specific embodiment, the first and third information can correspond to the 1-bit indication information described above.

[0068] Optionally, in this embodiment of the application, the first bit field used to carry the second information and the second bit field used to carry the fourth information at least partially overlap.

[0069] It should be understood that the embodiments of this application do not particularly limit the size of the first bit field and the second bit field. For example, the first bit field may be greater than the second bit field, or the second bit field may be greater than the first bit field, or the first bit field may be equal to the second bit field, as long as the first bit field and the second bit field at least partially overlap.

[0070] In other words, when the indication information carried in the PBCH indicates the presence of an RMSI, the second bit field in the PBCH can be used to carry the resource set for receiving the control information of the RMSI. When the indication information carried in the PBCH indicates the absence of an RMSI, the fourth information is essentially meaningless. Therefore, it is not necessary to continue using the second bit field to carry the fourth information; instead, some or all of the second bit field can be used to carry the second information. That is, in different scenarios, specific bit fields in the PBCH (i.e., the overlapping part of the first and second bit fields) can be reused to carry different information, thereby reducing signaling overhead.

[0071] For example, if the first bit field used to carry the second information is 8 bits and the second bit field used to carry the fourth information is 10 bits, and if the starting positions of the first bit field and the second bit field are the same, then the first bit field and the second bit field have an 8-bit overlap. When the third information indicates the presence of RMSI, the second bit field can be used to carry the resource set for the control information used to receive RMSI. When the first information indicates the absence of RMSI, the fourth information is actually meaningless, so it is not necessary to use the second bit field to continue carrying the fourth information. In this case, the first bit field can be used to carry the resource information of other synchronization signal blocks, thereby reducing signaling overhead.

[0072] Preferably, the first bit field and the second bit field reuse the same bit field, that is, the first bit field and the second bit field completely overlap.

[0073] Optionally, in some embodiments, the second bit field used to carry the fourth information can be an existing CORESET indication field, which can be used to carry CORESET information, i.e., the terminal device can know on which resources the control channel is detected based on the CORESET information. In this case, the first bit field used to carry the second information may include part or all of the CORESET indication field.

[0074] In other words, the second information can be carried in part or all of the CORESET indicator field carried by the PBCH. For example, when the first information carried by the first PBCH indicates that there is no RMSI, the CORESET information carried in the CORESET indicator field of the first PBCH is actually meaningless, or in other words, it is not necessary to fill the CORESET indicator field with CORESET information. In this case, the resource information of the second synchronization signal block can be filled in part or all of the CORESET indicator field. In this way, the terminal device can detect the second synchronization signal block according to the resource information of the second synchronization signal block filled in the CORESET indicator field, thereby reducing the complexity of the terminal device in detecting other SS blocks. Furthermore, using the existing CORESET indicator field to carry the resource information of other synchronization signal blocks can better ensure compatibility with existing technologies and also help reduce signaling overhead.

[0075] Optionally, in this embodiment of the application, the resource information of the second synchronization signal block may include the time-domain resource information and / or frequency-domain resource information of the second synchronization signal block.

[0076] For example, the frequency domain resource information of the second synchronization signal block can be the frequency domain resource location information of the second synchronization signal block, or it can be the offset information of the frequency domain position of the second synchronization signal block relative to the first synchronization signal block.

[0077] Optionally, in some embodiments, the RMSI includes at least one of the following:

[0078] Paging configuration parameters, cell selection information, access control information.

[0079] This means that the RMSI can be used for terminal devices to access the network.

[0080] The above text combined Figure 2 The method for transmitting information according to embodiments of this application is described in detail from the perspective of the terminal device. The following is in conjunction with Figure 3 This application describes in detail a method for transmitting information according to another embodiment of the present application from the perspective of a network device.
