Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method and apparatus for transmitting system information. Background Technology

[0002] Existing standards define dynamic spectrum sharing between Long Term Evolution (LTE) systems in 4th generation (4G) mobile communication systems and New Radio (NR) systems in 5th generation (5G) mobile communication systems. Dynamic spectrum sharing allows for the transmission of 4G and 5G data on the same frequency band through frequency division multiplexing (FDM) or time division multiplexing (TDM). Dynamic spectrum sharing enables smooth evolution between different standards, ensures the performance of 4G terminal devices, minimizes the impact on 4G terminal devices, and accelerates the pace of 5G deployment.

[0003] The standard has not yet defined how 5G cells and 6th generation (6G) mobile communication system cells share spectrum. Summary of the Invention

[0004] This application provides a method and apparatus for transmitting system information, which saves resource consumption and network energy consumption.

[0005] Firstly, a method for transmitting system information is provided. This method can be executed by a terminal or by components within the terminal (e.g., a processor, a chip, etc.). In this method, the terminal receives first system information in a first cell, the first system information indicating a first resource. The first system information is information about a first cell in a first communication standard. The terminal sends first request information on the first resource, the first request information being used to request the transmission of first information. The first information is information about a second cell in a second communication standard, and the first cell and the second cell share frequency domain resources.

[0006] Based on the above scheme, the first information can be triggered by the first request information sent by the terminal. Compared with the scheme where the base station needs to broadcast system information of both the first communication standard and the second communication standard, the technical solution provided by the embodiments of this application can reduce network energy consumption and reduce resource consumption.

[0007] In one possible implementation, the first resource belongs to the first cell. Based on the above scheme, when the first resource belongs to the first cell, the terminal can send the first request information through the first resource in the first cell, while the second cell does not reserve resources for the first request information, thus reducing resource waste. Furthermore, the base station can shut down the baseband module of the second communication standard, achieving energy saving.

[0008] In one possible implementation, the first resource belongs to the second cell. Based on the above scheme, when the second resource belongs to the second cell, the terminal can send the first request information in the second cell through the first resource. Compared to the terminal sending the first request information through the first cell's resource and then accessing the second cell, the latency of the terminal accessing the second cell can be reduced.

[0009] In one possible implementation, the first system information also carries the timing offset between the second cell and the first cell. Based on the above scheme, the terminal can obtain the timing offset between the second cell and the first cell, and therefore the terminal can synchronize with the second cell.

[0010] In one possible implementation, the first request information is carried in message 1 or message 3 of the random access procedure.

[0011] Based on the above scheme, the terminal can send the first request information through the random access procedure, and can request the base station to send the first information at the same time as random access, which can reduce latency.

[0012] In one possible implementation, the first system information indicates the random access sequence used by the first request information. Alternatively, the first system information indicates the timing of the random access channel.

[0013] Based on the above scheme, the terminal can send the first request information using the random access sequence or random access channel timing indicated by the first system information. Therefore, the base station can determine whether the terminal requests the first information based on the random access sequence or random access channel timing.

[0014] In one possible implementation, message 2 in the random access procedure carries first indication information, which indicates the control channel or first information for receiving the scheduling first information. Alternatively, message 4 in the random access procedure carries second indication information, which indicates the control channel or first information for receiving the scheduling first information.

[0015] Based on the above scheme, the terminal can be instructed to listen to the control channel or the first information through the first instruction information or the second instruction information, thereby reducing the energy consumption caused by the terminal frequently listening to the control channel or the first information.

[0016] In one possible implementation, message 2 does not carry the first indication information or message 4 does not carry the second indication information, and the terminal accesses the first cell through a random access procedure.

[0017] Based on the above scheme, the terminal can access the first cell without indicating the monitoring control channel and transmit data through the first cell, thus avoiding the problem of being unable to access the second cell and thus being unable to perform services.

[0018] In one possible implementation, the terminal receives third indication information, which indicates the start time of the control channel for scheduling the first information. This third indication information is carried in the first system information, message 2 in the random access procedure, or message 4 in the random access procedure. Alternatively, the control channel for scheduling the first information or the start time of the first information is predefined by the protocol.

[0019] Based on the above scheme, the terminal can determine the start time of the control channel based on the third indication information, thereby reducing the energy consumption caused by the terminal frequently monitoring the control channel.

[0020] In one possible implementation, the first system information also carries the period of the first information, and / or the period offset between the first information and the first system information.

[0021] Based on the above scheme, the terminal can determine the time unit (such as time slot or symbol) that may carry the first information based on the period and / or period offset of the first information, and listen to the control channel in the determined time unit to reduce the energy consumption caused by the terminal frequently listening to the control channel.

[0022] In one possible implementation, the number of times the first information is sent or the duration of the first information transmission is indicated by the first system information, or the number of times the first information is sent or the duration of the first information transmission is predefined by the protocol.

[0023] Based on the above scheme, the terminal can determine the number of times the first information is sent or the duration of the sending, thereby determining whether more first information will be sent.

[0024] In one possible implementation, the first system information also carries information about the control channel for scheduling the first information or the time-domain resources of the first information and / or information about the control channel for scheduling the first information or the frequency-domain resources of the first information.

[0025] In one possible implementation, the first system information also indicates whether the first information is being transmitted. Based on the above scheme, the terminal can determine whether the first information is being transmitted, and thus send a first request information to request the network device to transmit the first information if it is not being transmitted.

[0098] Figure 1 This is a schematic diagram of the architecture of a communication system 1000 provided in an embodiment of this application. Figure 1 As shown, the communication system 1000 includes a radio access network (RAN) 100, wherein the RAN 100 includes at least one RAN node (e.g., Figure 1 110a and 110b, collectively referred to as 110, may also include at least one terminal (such as...). Figure 1 RAN100, denoted as RAN100, comprises RAN nodes 120a-120j, collectively referred to as RAN120. RAN100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1(Not shown in the image). Terminal 120 is wirelessly connected to RAN node 110. Terminals and RAN nodes can be interconnected via wired or wireless means. Communication system 1000 may also include core network 200. RAN node 110 is connected to core network 200 via wireless or wired means. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN node. Communication system 1000 may also include Internet 300.

[0099] RAN100 can be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, a 6th generation (6G) radio access system, or a future radio access system as defined in the 3rd generation partnership project (3GPP). RAN100 can also include two or more of the above-mentioned different radio access systems. RAN100 can also be an open RAN (O-RAN).

[0100] RAN nodes, also known as radio access network devices, RAN entities, or access nodes, are used to help terminals access communication systems wirelessly. In one application scenario, an RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, or a base station in a future mobile communication system. RAN nodes can also be macro base stations (such as...). Figure 1 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1 110b in the middle can also be a relay node or a donor node.

[0101] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU performs the functions of the base station's Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP), and can also perform the functions of the Service Data Adaptation Protocol (SDAP). The DU performs the functions of the base station's Radio Link Control (RANC) and Medium Access Control (MAC) layers, and can also perform some or all of the physical layer functions. For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception. The CU and DU can be two independent RAN nodes or integrated into the same RAN node, such as within a baseband unit (BBU). The RU can be included in radio frequency equipment, such as in a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0102] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU can be called an open CU (O-CU), a DU can be called an open DU (O-DU), and an RU can be called an open RU (O-RU). The RAN nodes in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, a RAN node can be a server loaded with the corresponding software modules. The embodiments of this application do not limit the specific technology or device form used in the RAN nodes. For ease of description, a base station is used as an example of a RAN node in the following description.

[0103] A terminal is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from a base station. Terminals can also be called terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technology or device form used in the terminal.

[0104] Base stations and terminals can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminals.

[0105] The roles of base stations and terminals can be relative, for example, Figure 1 The helicopter or drone 120i can be configured as a mobile base station. For terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminals can be collectively referred to as communication devices. Figure 1 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal functions.

[0106] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0107] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal functions.

[0108] In this application, the base station sends downlink signals or downlink information to the terminal, with the downlink information carried on the downlink channel; the terminal sends uplink signals or uplink information to the base station, with the uplink information carried on the uplink channel. To communicate with the base station, the terminal needs to establish a radio connection on a cell controlled by the base station. The cell with which the terminal has established a radio connection is called the terminal's serving cell. When the terminal communicates with this serving cell, it is also susceptible to interference from signals from neighboring cells.

[0109] It is understood that in the embodiments of this application, PDCCH and PDSCH are only examples of downlink control channels and downlink data channels. In different systems and different scenarios, data channels and control channels may have different names, and the embodiments of this application do not limit this.

[0110] In this application, entity A sends information to entity B, either directly or indirectly through other entities. Similarly, entity B receives information from entity A, either directly or indirectly through other entities. Entities A and B can be RAN nodes or terminals, or modules within RAN nodes or terminals. Information transmission and reception can be between RAN nodes and terminals, such as between a base station and a terminal; between two RAN nodes, such as between a CU and a DU; or between different modules within a single device, such as between a terminal chip and other modules of the terminal, or between a base station chip and other modules of the base station.

[0111] The communication systems and service scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0112] In the early stages of NR network construction, on the one hand, operators wanted to quickly introduce NR networks, and on the other hand, the overall penetration rate of NR terminals was low, and the growth rate of NR traffic was inconsistent in different regions. This brought great planning difficulties to the LTE frequency band refarming to NR, affecting the progress of NR network construction.

[0113] See Figure 2 Therefore, existing standards have introduced dynamic spectrum sharing between LTE and NR. Dynamic spectrum sharing allows 4G and 5G data to be transmitted on the same frequency band through frequency division multiplexing or time division multiplexing. Dynamic spectrum sharing enables smooth evolution between different standards, ensures the performance of 4G terminals, minimizes the impact on 4G terminals, and accelerates the pace of 5G deployment.

[0114] In 5G, always-on signals include SSBs (Service Signals Blocks). During initial access, the terminal uses SSBs to perform cell search, time-frequency synchronization, and automatic gain control (AGC) adjustments. Additionally, SSBs can carry master information blocks (MIBs). The terminal receives the PDCCH (Plan-Do-Chat Communication) of System Information Block 1 (SIB1) based on the MIB information. SIB1 is carried by the PDSCH (Plan-Do-Chat Communication) scheduled by the PDCCH. The terminal can receive the PDCCH based on the MIB information and receive SIB1 based on the information carried by the PDCCH. Upon receiving SIB1, the terminal can obtain the necessary system information for the access cell and complete the initial access process.

[0115] SSBs are transmitted periodically, typically with a period of 20ms, but other values ​​are also possible, such as 5ms, 10ms, 40ms, 80ms, or 160ms. In the frequency domain, one SSB can occupy 20 RBs, and in the time domain, an SSB can occupy 4 consecutive orthogonal frequency division multiplexing (OFDM) symbols.

[0116] SIB1 carries a significant amount of information. Since SIB1 carries system information, it needs to be designed so that all terminals, including those in the cell center and at the cell edge, can receive it. Therefore, the base station may allocate more time-frequency resources to transmit SIB1 to improve reliability. For example, in the frequency domain, SIB1 typically occupies a large bandwidth, such as the full bandwidth part (BWP) or full bandwidth scheduling; in the time domain, SIB1 may occupy a large number of symbols, such as 12 symbols. The PDCCH scheduling SIB1 occupies 2 symbols, so transmitting SIB1 may require one time slot in the time domain.

[0117] To enable initial terminal access, base stations periodically broadcast SSB and SIB1, which incurs some time-frequency resource overhead. Additionally, the periodic broadcast signals also contribute to network power consumption. This network power consumption primarily includes baseband power consumption and radio frequency (RF) power consumption. Once a 5G cell is activated, the base station's baseband module typically remains active, resulting in baseband power consumption. Furthermore, during broadcast signals, the base station transmits RF signals via its RF module, incurring RF module overhead.

[0118] In this embodiment of the application, to facilitate a smooth evolution from 5G to 6G, spectrum sharing between 5G and 6G cells is proposed. This spectrum sharing between 5G and 6G cells can also be referred to as DSS or multi-radioaccess technology spectrum sharing (MRSS). Once MRSS is enabled on a carrier, both 5G and 6G terminal devices can access that carrier. For ease of description, this carrier can be referred to as an MRSS carrier. On the MRSS carrier, network devices must transmit both 5G SSB and SIB1, as well as 6G SSB and SIB1.

[0119] In a 5G single-mode scenario, network devices can broadcast 5G SSB and SIB1 to support initial access by terminal devices. Compared to the 5G single-mode scenario, in the MRSS scenario, network devices must broadcast both 5G and 6G SSB and SIB1. It can be seen that in the MRSS scenario, the number of signals transmitted always increases, thus increasing both network power consumption and resource overhead.

[0120] Therefore, embodiments of this application provide a method for transmitting system information. In this method, a terminal can receive first system information of a first communication standard in a first cell. This first system information can indicate a first resource. The terminal can send first request information on the first resource, which can be used to request a base station to send first information of a second communication standard.

[0121] In this method, the second cell and the first cell share frequency domain resources, such as shared carriers. In one possible scenario, the frequency domain resources of the second cell and the first cell can be completely identical. In another possible scenario, the frequency domain resources of the second cell and the first cell can be partially identical.

[0122] Based on the above scheme, the first information can be triggered by the first request information sent by the terminal. Compared with the scheme where the base station needs to broadcast both 5G SSB and SIB1 and 6G SSB and SIB1, the technical solution provided by the embodiments of this application can reduce network energy consumption and reduce resource consumption.

[0123] See Figure 3 The following is an exemplary flowchart of a system information transmission method provided in this application embodiment, which may include the following steps:

[0124] S301: The base station sends the first system information in the 5G cell.

[0125] Correspondingly, the terminal receives the first system information in the 5G cell.

[0126] The first system information may carry information about the first resource. This first resource may be used to carry the first request information.

[0127] S302: The terminal sends a first request message on the first resource.

[0128] Accordingly, the base station receives the first request information on the first resource.

[0129] The first request information can be used to request the base station to send first information.

[0130] Figure 3 In the illustrated embodiment, the first system information is the information of the first cell in the first communication standard, and the first information is the information of the second cell in the second communication standard. The second communication standard is different from the first communication standard. For example, the first communication standard is 5G, the first system information is 5G SIB1, the first cell is a 5G cell, the second communication standard is 6G, the first information can be 6G SSB or 6G SIB1, and the second cell is a 6G cell.

[0131] In some embodiments, the first request information may be carried in message 1 (MSG1) during the random access procedure.

[0132] In one possible scenario, the first resource could be a random access resource belonging to a 5G cell. For example, the first resource could include a random access channeloccasion (RO) that a 5G cell can use, as predefined by the protocol. In this case, the terminal sends a first request to the base station using the resources of the 5G cell. Therefore, 6G cells do not need to reserve random access resources, and the uplink and downlink modules of the 6G baseband module in the base station can be temporarily shut down for energy saving.

[0133] For example, a terminal can send MSG1 to a base station via a physical random access channel (PRACH). MSG1 may carry a random access sequence (or preamble sequence). The terminal can receive 5G SSBs from the base station. The terminal can detect the power of the 5G SSB and select the 5G SSB with the highest power. The terminal can randomly select an RO (Redirecting Operator) from the ROs associated with the 5G SSB with the highest power and send MSG1. MSG1 may carry first request information.

[0134] In one example, 5G SIB1 may indicate the first request information, or the random access sequence used by MSG1. Therefore, the base station can determine whether the terminal requests the base station to send the first information based on this random access sequence. Alternatively, if MSG1 uses the random access sequence indicated by 5G SIB1, then 5G SIB1 can be considered to carry the first request information.

[0135] In the example above, 5G SIB1 can instruct the terminal to send an MSG1 preamble sequence carrying the first request information. For example, the MSG1 sequence used to send the first request information is still based on the 5G standard protocol, and 5G SIB1 indicates that at least one MSG1 sequence is used to represent sending the first request information. The base station can distinguish whether the current terminal is requesting to send 6G SIB1 or requesting traditional 5G transmission, such as accessing a 5G cell or obtaining uplink synchronization from a 5G cell, based on different MSG1 sequences.

[0136] For example, 5G SIB1 can instruct a portion of the RO resources on a 5G cell to be used to indicate the transmission of a first request message. Sending MSG1 on the specified RO resource indicates a request for the base station to send 6G SIB1. It is understood that 5G terminals that do not support 6G will not be configured with such RO resources.

[0137] Optionally, in the above scenario, since the terminal sends the first request information to the base station through the resources of the 5G cell, meaning the terminal initiates initial access in the 5G cell, and the 5G cell and the 6G cell may not be strictly synchronized, the base station can send a timing offset between the 5G cell and the 6G cell to the terminal. For example, the 5G SIB1 can carry the timing offset between the 5G cell and the 6G cell. For instance, the 5G SIB1 can carry the downlink timing offset between the 6G cell and the 5G cell, and / or the uplink timing advance (TA) offset between the 6G cell and the 5G cell, and / or the uplink TA of the 6G cell, enabling the terminal to achieve timing synchronization with the 6G cell, such as uplink timing synchronization and / or downlink timing synchronization.

[0138] In another possible scenario, the first resource could be a random access resource belonging to a 6G cell. In this case, the random access resources that the 6G cell can use can be predefined, including random access sequences and / or ROs. The terminal can send a first request message to the base station using the resources of the 6G cell. The uplink module in the 6G baseband module of the base station cannot be turned off, but the downlink module can be turned off for energy saving.

[0139] Optionally, the 5G SIB1 may instruct the terminal to send a random access sequence for MSG1 (or first request information). The random access sequence of the 6G cell corresponds to the RO of the 6G cell and can be predefined in the protocol. Therefore, the terminal can determine the RO carrying MSG1 based on the preamble sequence indicated by the 5G SIB1, and send MSG1 carrying the first request information on the determined RO. The base station can determine whether the terminal requests the base station to send the first information based on this random access sequence or RO.

[0140] For example, a terminal can use the RO of a 6G cell to send a first request message to the base station. For instance, a preamble sequence and / or RO of the 6G cell can be defined, or the preamble sequence and / or RO of the 6G cell can be configured via 5G SIB1. Upon receiving 5G SIB1, the terminal determines that the 5G cell carrier is an MRSS carrier, and then the terminal can use the RO of the 6G cell to send MSG1 to the base station.

[0141] In the above scenario, since the terminal transmits MSG1 on the resources of the 6G cell, it needs to obtain the TA of the 6G cell and send MSG1 carrying the first request information to the base station based on the TA. Optionally, 5G SIB1 may carry the downlink timing offset (DL time offset) of the 6G cell and the 5G cell, and / or the uplink timing advance (TA) of the 6G cell and the 5G cell, and / or the uplink TA of the 6G cell, enabling the terminal to obtain timing synchronization with the 6G cell, such as uplink timing synchronization and / or downlink timing synchronization.

[0142] In other embodiments, the first request information may be carried in message 3 (MSG3) during the random access procedure. The resource carrying MSG3 may be indicated by message 2 (MSG2). For example, after receiving MSG1, the base station sends MSG2 to the terminal; MSG2 is also known as a random access response (RAR). The RAR information may indicate the time-frequency resource carrying MSG3. The terminal may then send MSG3 carrying the first request information on the time-frequency resource indicated by the RAR.

[0143] In this scenario, it is not necessary to configure dedicated time-frequency resources for carrying the first request information in 5G SIB1. Optionally, 5G SIB1 can instruct the first request information to be carried via MSG1 or via MSG3. For example, when 5G SIB1 instructs the first request information to be carried via MSG1, the terminal can carry the first request information in MSG1. As another example, when 5G SIB1 instructs the first request information to be carried via MSG3, the terminal can carry the first request information in MSG3.

[0144] In other embodiments, the 5G SIB1 can be configured or predefined via a protocol to use a 6G-specific scheduling request (SR) resource (first resource) carrying first request information.

[0145] Optionally, a wake-up signal (WUS) can be used to request the base station to send the first information in the 6G cell. The WUS can be a sounding reference signal (SRS), a low peak-to-average power ratio (PAPR) sequence such as the Zadoff-Chu (ZC) sequence, or a pseudo-random sequence (gold sequence), etc. 5G SIB1 can indicate the first resource carrying the WUS.

[0146] S303: The base station sends the first information in the 6G cell.

[0147] Correspondingly, the terminal receives the first information in the 6G cell.

[0148] based on Figure 3 The technical solution shown allows the first information of a 6G cell to be sent based on the terminal's request, that is, sent on demand, which can reduce network energy consumption and resource consumption.

[0149] The first piece of information mentioned above can be either 6G SSB or 6G SIB1, which will be described in detail below for different scenarios.

[0150] Case 1: The first information includes 6G SIB1.

[0151] In scenario 1, 5G SIB1 can carry configuration information for control channels used to schedule 6G SIB1, such as PDCCH. For ease of description, the control channel for scheduling 5G SIB1 will be referred to as 5G PDCCH, and the channel for scheduling 6G SIB1 will be referred to as 6GPDCCH.

[0152] In one possible implementation, the 5G SIB1 may carry one or more of the following information:

[0153] 1) Sub-carrier spacing (SCS) of a 6G cell. For example, a first field, such as `subCarrierSpacingCommon-6G`, can be carried in the 5G SIB1, indicating the sub-carrier spacing of the 6G cell. For instance, the first field can be 1 bit of information, indicating 15kHz or 30kHz in the FR1 band, and 60kHz or 120kHz in the FR2 band.

[0154] 2) Time-domain position of the preceding DMRS for the PDSCH carrying 6G SIB1. For example, 5G SIB1 may carry a second field, such as dmrs-TypeA-Position-6G, which indicates the time-domain position of the preceding DMRS for the PDSCH carrying 6G SIB1. The preceding DMRS can be located before the PDSCH transmission carrying 6G SIB1 (conversely, the additional DMRS is located after the PDSCH transmission), and its length can be X symbols. The second field can indicate the time-domain start position of these X symbols. Optionally, the second field can also indicate the value of X, or the value of X can be predefined by the protocol, for example, X can be 1, or other values, such as 2. For example, the time-domain start position of the X symbols can start from the 3rd symbol or the 4th symbol. Assuming the symbol numbering in the time slot starts from 0, the second field can indicate "pos2" or "pos3", meaning that the symbols carrying the PDSCH of 6G SIB1 start from the third or fourth symbol.

[0155] 3) 6G Cell Barrier Information. This 6G cell barrier information can indicate whether or not to prohibit 6G terminals from accessing the 6G cell. For example, the 5G SIB1 can carry a third field, such as cellBarred-6G. This third field can be a 1-bit information; a value of 0 indicates that 6G terminals are not prohibited from accessing the 6G cell, and a value of 1 indicates that 6G terminals are prohibited from accessing the 6G cell; conversely, a value of 1 indicates that 6G terminals are not prohibited from accessing the 6G cell, and a value of 0 indicates that 6G terminals are prohibited from accessing the 6G cell.

[0156] 4) Cell reselection information for 6G cells on the same frequency. For example, 5G SIB1 can carry a fourth field, such as intraFreqReselection-6G, indicating whether a 6G terminal is allowed to access a neighboring cell on the same frequency. For instance, this fourth field can be a 1-bit information. When this 1-bit information is 0, it indicates that the 6G terminal is allowed to access the neighboring cell on the same frequency; when the 1-bit information is 1, it indicates that the 6G terminal is not allowed to access the neighboring cell on the same frequency. Conversely, when the 1-bit information is 1, it indicates that the 6G terminal is allowed to access the neighboring cell on the same frequency; when the 1-bit information is 0, it indicates that the 6G terminal is not allowed to access the neighboring cell on the same frequency.

[0157] 5) Timing offset between 6G and 5G cells. Although 5G and 6G cells are on the same carrier, timing offsets may exist between them due to hardware differences or imperfections. A 6G terminal receives the 5G SSB first, initially accesses the 5G cell, and achieves downlink timing synchronization with the 5G cell. However, at this point, the 6G terminal has not yet achieved timing synchronization with the 6G cell. Therefore, the timing offset between the 6G and 5G cells is indicated via 5G SIB1, such as the downlink timing offset (DL time offset), enabling the 6G terminal to achieve downlink timing synchronization with the 6G cell.

[0158] 6) Information on the time-domain resources and / or frequency-domain resources of the 6G PDCCH. For example, 5G SIB1 may indicate the frequency-domain resources (such as 6G CORESET) and / or time-domain resources (6G search space) of the 6G PDCCH.

[0159] In some embodiments, 5G SIB1 can indicate the frequency domain resources of the 6G PDCCH. For example, see [link to relevant documentation]. Figure 4A 5GSIB1 can indicate the frequency domain offset between the frequency domain resources of the 6G PDCCH and those of the 5G PDCCH (such as 5G CORESET#0). The 5G PDCCH can be used to schedule first system information, such as 5G SIB1. Optionally, the time domain resources of the 6G PDCCH can be predefined by the protocol, such as the 6G PDCCH time domain resources being the same as those of the 5G PDCCH (such as the 5G search space). The terminal can determine the frequency domain location of the 6G PDCCH based on the frequency domain resources indicated by 5G SIB1, such as the frequency domain offset between the 6G PDCCH and 5G PDCCH frequency domain resources.

[0160] In other embodiments, 5G SIB1 can indicate the time-domain resources of the 6G PDCCH. For example, see [link to documentation]. Figure 4B 5GSIB1 can indicate the time domain offset between the time domain resources of the 6G PDCCH and the time domain resources of the 5G PDCCH. Optionally, the frequency domain resources of the 6G PDCCH can be predefined by the protocol, such as the frequency domain resources of the 6G PDCCH being the same as those of the 5G PDCCH. The terminal can determine the time domain location of the 6G PDCCH based on the time domain resources of the 6G PDCCH indicated by 5G SIB1, such as the time domain offset between the time domain resources of the 6G PDCCH and the time domain resources of the 5G PDCCH.

[0161] In other embodiments, 5G SIB1 can indicate the frequency domain resources and time domain resources of the 6G PDCCH. For example, see [link to documentation]. Figure 4C 5G SIB1 can indicate the frequency domain offset between the frequency domain resources of the 6G PDCCH and the frequency domain resources of the 5G PDCCH, and 5G SIB1 can indicate the time domain offset between the time domain resources of the 6G PDCCH and the time domain resources of the 5G PDCCH. The terminal can determine the time domain position and frequency domain position of the 6G PDCCH based on the frequency domain resources and time domain resources of the 6G PDCCH indicated by 5G SIB1.

[0162] In one possible implementation, the transmission period of 6G SIB1 can be predefined by the protocol or indicated by 5G SIB1. For example, the period of 6G SIB1 can be predefined by the protocol to be the same as the period of 5G SIB1, or the period of 6G SIB1 can be predefined by the protocol, such as 20ms or 40ms. As another example, 5G SIB1 can indicate that the period of 6G SIB1 is the same as the period of 5G SIB1, or 5G SIB1 can indicate the period of 6G SIB1, such as 20ms or 40ms.

[0163] Based on the above scheme, according to the definition in the standard, the information of the control channel for scheduling 6G SIB1 should be carried by 6G SSB. In the above scheme provided in the embodiments of this application, the configuration information of the control channel for scheduling 6G SIB1 can be obtained through 5G SIB1, which reduces the resource overhead and network energy consumption of 6G SSB. Since the terminal does not need to receive 6G SSB, the latency of the terminal accessing the 6G cell can be reduced.

[0164] In scenario 1, based on the information carried by the 5G SIB1, the terminal can receive the 6G PDCCH that schedules the 6G SIB1, and receive the 6G SIB1 based on the information carried by the 6G PDCCH. In one possible implementation, the terminal can start listening to the 6G PDCCH after receiving the RAR.

[0165] For example, the protocol can predefine that the terminal will start listening to the 6G PDCCH after receiving a RAR (or MSG2). For instance, after the terminal sends an MSG1 carrying first request information via a first resource, the base station can send a RAR to the terminal. The terminal can then start listening to the 6G PDCCH to obtain the information carried by the 6G PDCCH and receive 6G SIB1.

[0166] For example, the RAR can carry first indication information, which can instruct the terminal to start listening to the 6G PDCCH. For instance, the first indication information can be a 1-bit indication. A value of 0 indicates that the terminal is not listening to the 6G PDCCH, and a value of 1 indicates that the terminal is listening to the 6G PDCCH. Conversely, a value of 1 indicates that the terminal is not listening to the 6G PDCCH, and a value of 0 indicates that the terminal is listening to the 6G PDCCH. Again, for instance, if the RAR carries the first indication information, it can be considered that the terminal is instructing to start listening to the 6G PDCCH; if the RAR does not carry the first indication information, it can be considered that the terminal is instructing to not listen to the 6G PDCCH.

[0167] Optionally, if the RAR does not carry the first indication information, or if the first indication information indicates that the terminal does not listen to the 6GPDCCH, the terminal can access the 5G cell through a random access procedure.

[0168] In another possible implementation, the terminal can start listening to the 6G PDCCH after receiving MSG4. For example, the protocol can predefine when the terminal will start listening to the 6G PDCCH after receiving MSG4. Exemplarily, the terminal can carry first request information in MSG1 or MSG3. If the base station receives MSG3, it can send MSG4 to the terminal. Upon receiving MSG4, the terminal can start listening to the 6G PDCCH to obtain the information carried by the 6G PDCCH and receive 6G SIB1.

[0169] For example, MSG4 can carry a second indication, which can instruct the terminal to start listening to the 6G PDCCH. Exemplarily, the second indication can be a 1-bit indication. A value of 0 indicates that the terminal is not listening to the 6G PDCCH, and a value of 1 indicates that the terminal is listening to the 6G PDCCH. Conversely, a value of 1 indicates that the terminal is not listening to the 6G PDCCH, and a value of 0 indicates that the terminal is listening to the 6G PDCCH. Again, for example, if message 4 carries the second indication, it can be considered that the terminal has started listening to the 6G PDCCH; if message 4 does not carry the second indication, it can be considered that the terminal is not listening to the 6G PDCCH.

[0170] Optionally, if message 4 does not carry the second indication information, or if the second indication information indicates that the terminal does not listen to the 6GPDCCH, the terminal can access the 5G cell through a random access procedure.

[0171] In one example, if the terminal is sending MSG1 in a 5G cell, meaning the first resource belongs to the 5G cell, the base station's 6G baseband module might be off. After receiving the terminal's first request information, the base station's 5G baseband module will determine whether the terminal is requesting the base station to send 6G SIB1 via MSG1 or MSG3. If the base station determines that the terminal is requesting 6G SIB1, the 5G baseband module can send an enable instruction to the 6G baseband module, turning it on from the off state to begin sending 6G SIB1.

[0172] Therefore, considering that the 6G baseband module may need a certain amount of time to transition from an off state to an on state, the terminal may need to start listening to the 6G PDCCH after receiving the RAR or message 4, after a first time interval t. Here, t can be an absolute time, such as the terminal starting to listen to the 6G PDCCH after an interval of t ms. Alternatively, t can be a relative time, such as the time unit difference between the terminal and the time unit (e.g., symbol or time slot) used by message 4 or the RAR. For example, after receiving message 4, the terminal may start listening to the 6G PDCCH at the (t+1)th symbol or the tth symbol after the symbol used by message 4.

[0173] Optionally, the value of t can be predefined by the protocol. Alternatively, the value of t can be indicated by 5G SIB1, RAR, or message 4.

[0174] In another example, 5G SIB1 can indicate the period and period offset of 6G SIB1. Based on the period and period offset of 6G SIB1 indicated by 5G SIB1, the terminal can determine all possible time slots carrying 6G SIB1, and can then listen to the 6G PDCCH in the determined time slot. Considering that the 6G baseband module needs a certain amount of time to transition from an off state to an on state, the terminal can also offset the determined time slot by x ms or x time units to start listening to the 6G PDCCH.

[0175] It should be noted that the value of x can be predefined, indicated by the base station (such as through 5G SIB1), or preconfigured.

[0176] Based on the above scheme, the terminal can determine when to start listening to the 6G PDCCH in order to avoid the energy consumption caused by frequent PDCCH listening.

[0177] In this embodiment, the base station can periodically send 6G SIB1 based on the terminal's first request information. In one possible implementation, the base station can periodically send 6G SIB1 until there is no connected 6G terminal. Here, a 6G terminal can be understood as a terminal accessing a 6G cell. For example, see [link to relevant documentation]. Figure 5AThe 6G SIB1 can be configured with a timer, such as SIB1-release-timer. This timer starts when the last terminal in the 6G cell is released from the radio resource control (RRC) connected state. The 6G baseband module of the base station stops sending 6G SIB1 when the timer expires.

[0178] Understandably, when multiple 6G terminals exist, the timer for a particular 6G terminal may expire earlier because other 6G terminals may be being served at that time. From the perspective of a particular 6G terminal, once its timer expires, that 6G terminal considers that 6G SIB1 transmission has stopped.

[0179] In another possible implementation, the base station can periodically send 6G SIB1 for a period of time based on the terminal's first request information. After a period of time, although the base station's 6G baseband module remains on and there may still be terminals in RRC connection state in the 6G cell, the base station no longer needs to send 6G SIB1. This is because the purpose of 6G SIB1 is to allow the terminal to access the 6G cell; once the terminal enters RRC connection state, 6G SIB1 is no longer needed. Therefore, the base station can stop sending 6G SIB1 in advance, reducing time and frequency resource overhead.

[0180] Optionally, since 6G SIB1 is for the initial access of the terminal, the period of 6G SIB1 can be more frequent. For example, the period of 6G SIB1 can be less than 20ms, so that the terminal can complete the reception and parsing of 6G SIB1 earlier and access the 6G cell.

[0181] See Figure 5B After receiving the first request information, the base station can periodically send 6G SIB1 for a period of time. The period of 6G SIB1 can be less than 20ms, and 6G SIB1 is relatively faster than... Figure 5A The 6G SIB1 shown can be stopped from transmitting in advance. At this time, there may still be terminals in the RRC connected state in the 6G cell.

[0182] In one example, the period and number of transmissions for 6G SIB1 can be predefined through the protocol. For instance, if the base station receives the terminal's first request information, the base station can start transmitting 6GSIB1 according to the predefined period, such as a period of 5ms, and continue transmitting the protocol-predetermined number of times, such as 10 times.

[0183] In another example, 6G SIB1 can indicate the period of 6G SIB1. Optionally, 6G SIB1 can also indicate the remaining number of transmissions or the remaining transmission time of 6G SIB1.

[0184] Based on the above scheme, the base station can stop transmitting 6G SIB1, further saving energy consumption and resource costs.

[0185] See Figure 6 The diagram illustrates a scenario of the 6G SIB1 transmission method in an embodiment of this application. Figure 6 As shown, the terminal can receive a 5G SSB. This 5G SSB may carry a MIB, and the terminal receives the 5G PDCCH scheduling 5G SIB1 based on the information carried in the MIB. The terminal can receive 5G SIB1 according to the scheduling information indicated by the 5G PDCCH. The 5G SIB1 may indicate a first resource. The terminal can send a first request message to the base station on the first resource, which requests the base station to send 6G SIB1. The base station can send 6G SIB1 in the second cell. Additionally, the 5G SIB1 may carry the configuration information of the 6G PDCCH for 6G SIB1. The terminal can receive the 6G PDCCH according to the configuration information carried by the 5G SIB1, and receive 6G SIB1 according to the scheduling information of the 6G PDCCH, thereby completing the initial access with the 6G cell.

[0186] As can be seen, the above-mentioned solution provided in this application embodiment can obtain the configuration information of the control channel for scheduling 6G SIB1 through 5G SIB1, thereby reducing the resource overhead and network energy consumption of 6G SSB.

[0187] Scenario 2: The first piece of information includes 6G SSB.

[0188] In scenario 1, the 5G SIB1 can carry configuration information for scheduling the PDCCH of 6G SIB1. Therefore, the base station does not need to send the 6G SSB. In scenario 2, the base station can send the 6G SSB based on the terminal's first request information. The 6G SSB can carry a MIB, and the terminal can determine the PDCCH information for scheduling 6G SIB1 based on the MIB, thereby receiving the 6G PDCCH and 6G SIB1.

[0189] In scenario 2, the base station will only send 6G SIB1 if the terminal requests it to send a 6G SSB. In scenario 2, the first request information can be used to request the base station to send a 6G SSB. After receiving the 6G SSB, the terminal can listen to the 6G PDCCH to receive 6G SIB1.

[0190] In one possible implementation, the 5G SIB1 may carry configuration information for the 6G SSB, which may include one or more of the following information.

[0191] 1) Information on the time-domain resources and / or frequency-domain resources of the 6G SSB.

[0192] In some embodiments, 5G SIB1 can indicate the frequency domain resources of 6G SSB. For example, see [link to documentation]. Figure 7A 5GSIB1 can indicate the frequency domain offset between the frequency domain resources of the 6G SSB and the frequency domain resources of the 5G SSB. Optionally, the time domain resources of the 6G SSB can be predefined by the protocol, such as the time domain resources of the 6G SSB being the same as those of the 5G SSB.

[0193] In other embodiments, 5G SIB1 may indicate the time-domain resources of 6G SSB. For example, see [link to relevant documentation]. Figure 7B 5GSIB1 can indicate the time domain offset between the time domain resources of the 6G SSB and the time domain resources of the 5G SSB. Optionally, the frequency domain resources of the 6G SSB can be predefined by the protocol, such as the frequency domain resources of the 6G SSB being the same as those of the 5G SSB.

[0194] In other embodiments, 5G SIB1 can indicate the time-domain and frequency-domain resources of 6G SSB. For example, see [link to documentation]. Figure 7C 5G SIB1 can indicate the time domain offset between the time domain resources of 6G SSB and the time domain resources of 5G SSB. Additionally, 5G SIB1 can indicate the frequency domain offset between the frequency domain resources of 6G SSB and the frequency domain resources of 5G SSB.

[0195] 2) Timing offset between 5G and 6G cells. Although 5G and 6G cells are on the same carrier, timing offsets may exist between them due to hardware differences or imperfections. A 6G terminal receives the 5G SSB first, initially accesses the 5G cell, and achieves downlink timing synchronization with the 5G cell. However, at this point, the 6G terminal has not yet achieved timing synchronization with the 6G cell. Therefore, the timing offset between the 6G and 5G cells is indicated via 5G SIB1, such as the downlink timing offset (DL time offset), enabling the terminal to achieve downlink timing synchronization with the 6G cell.

[0196] 3) Information indicating whether 6G SSB is transmitting. 5G SIB1 can indicate whether 6G SSB is transmitting. For example, 5GSIB1 can include a fifth field that indicates whether 6G SSB is transmitting. For instance, the fifth field can be a 1-bit indication. A value of 0 indicates that 6G SSB is not transmitting, and a value of 1 indicates that 6G SSB is transmitting. Conversely, a value of 1 indicates that 6G SSB is not transmitting, and a value of 0 indicates that 6G SSB is transmitting. Again, for instance, if 5GSIB1 includes a fifth field, it indicates that 6G SSB is transmitting; if 5G SIB1 does not include a fifth field, it indicates that 6G SSB is not transmitting.

[0197] Optionally, if 5G SIB1 indicates that 6G SSB is being transmitted, 5G SIB1 can also indicate the estimated duration of 6G SSB transmission. The terminal can then determine whether to receive 6G SSB based on the information indicated by 5G SIB1 and its service requirements. If 6G SSB is being transmitted, the terminal does not need to send a first request message to the base station and does not need to request the base station to send 6G SSB.

[0198] In one possible implementation, the time at which the terminal starts receiving SSB can be implemented with reference to the method in Case 1 for determining the time at which the terminal starts listening to the 6G PDCCH.

[0199] In some embodiments, the terminal can begin receiving 6G SSB after receiving RAR. For example, the protocol can predefine that the terminal will begin receiving 6G SSB after receiving RAR (or MSG2). For instance, after the terminal sends MSG1 carrying first request information via a first resource, the base station can send RAR to the terminal. The terminal can then begin receiving 6G SSB to obtain the information carried by the 6G SSB and receive 6G SIB1.

[0200] For example, the RAR can carry first indication information, which can instruct the terminal to start receiving 6G SSB. For instance, the first indication information can be a 1-bit indication. A value of 0 indicates that the terminal will not receive 6G SSB, and a value of 1 indicates that the terminal will receive 6G SSB. Conversely, a value of 1 indicates that the terminal will not receive 6G SSB, and a value of 0 indicates that the terminal will receive 6G SSB. For another example, if the RAR carries the first indication information, it can be considered that the terminal has started receiving 6G SSB; if the RAR does not carry the first indication information, it can be considered that the terminal has not received 6G SSB.

[0201] Optionally, if the RAR does not carry the first indication information, or if the first indication information indicates that the terminal does not receive 6GSSB, the terminal can access the 5G cell through a random access procedure.

[0202] In another possible implementation, the terminal can begin receiving 6G SSB after receiving MSG4. For example, the protocol can predefine when the terminal will begin receiving 6G SSB after receiving MSG4. Exemplarily, the terminal can carry first request information in MSG1 or MSG3. If the base station receives MSG3, it can receive MSG4 from the terminal. Upon receiving MSG4, the terminal can begin receiving 6G SSB, thereby obtaining the information carried by the 6G SSB to receive 6G SIB1.

[0203] For example, MSG4 can carry a second indication information, which can instruct the terminal to start receiving 6GSSB. Exemplarily, the second indication information can be a 1-bit indication. A value of 0 indicates that the terminal will not receive 6GSSB, and a value of 1 indicates that the terminal will receive 6GSSB. Conversely, a value of 1 indicates that the terminal will not receive 6GSSB, and a value of 0 indicates that the terminal will receive 6GSSB. Again, for example, if message 4 carries the second indication information, it can be considered that the terminal has started receiving 6GSSB; if message 4 does not carry the second indication information, it can be considered that the terminal has not received 6GSSB.

[0204] Optionally, if message 4 does not carry the second indication information, or if the second indication information indicates that the terminal does not receive 6GSSB, the terminal can access the 5G cell through a random access procedure.

[0205] In one example, if the terminal sends MSG1 in a 5G cell, meaning the first resource belongs to the 5G cell, the base station's 6G baseband module might be off. After receiving the terminal's first request information, the base station's 5G baseband module will determine whether the terminal requests the base station to send a 6G SSB via MSG1 or MSG3. If the base station determines that the terminal requests a 6G SSB, the 5G baseband module can send an enable instruction to the 6G baseband module, turning it on from the off state to begin sending the 6G SSB.

[0206] Therefore, considering that the 6G baseband module may need a certain amount of time to transition from an off state to an on state, the terminal may need to wait a second time interval t' after receiving the RAR or message 4 before starting to receive the 6G SSB. Here, t' can be an absolute time, such as the terminal starting to receive the 6G SSB at a time interval of t'ms. Alternatively, t' can be a relative time, such as the time unit difference between the 6G SSB and the time unit (e.g., symbol or time slot) used by message 4 or the RAR. For example, after receiving message 4, the terminal may start receiving the 6G SSB at the t'+1th symbol or the t'th symbol after the symbol used by message 4.

[0207] Optionally, the value of t' can be predefined by the protocol. Alternatively, the value of t' can be indicated by 5G SIB1, RAR, or message 4.

[0208] In another example, 5G SIB1 can indicate the period and period offset of 6G SSB. The terminal can determine all possible time slots carrying 6G SSB based on the period and period offset indicated by 5G SIB1, and can receive 6G SSB in the determined time slot. Considering that the 6G baseband module needs a certain amount of time to go from off to on, the terminal can also offset the determined time slot by x'ms or x' time units to start receiving 6G SSB.

[0209] It should be noted that the value of x' can be predefined, indicated by the base station (such as through 5G SIB1), or preconfigured.

[0210] Based on the above scheme, the terminal can determine when to start receiving 6G SSB, so as to avoid the energy consumption caused by frequent 6G SSB searches.

[0211] See Figure 8 This illustration shows a scenario diagram of the transmission methods of 6G SSB and 6G SIB1 in an embodiment of this application. Figure 8 As shown, the terminal can receive a 5G SSB. This 5G SSB may carry a MIB, and the terminal receives the 5G PDCCH scheduling 5G SIB1 based on the information carried in the MIB. The terminal can receive 5G SIB1 according to the scheduling information indicated by the 5G PDCCH. 5G SIB1 may indicate a first resource. The terminal can send a first request message to the base station on the first resource, which requests the base station to send a 6G SSB. The base station can send the 6G SSB in the second cell. Additionally, 5G SIB1 may carry relevant information about the 6G SSB. The terminal can receive the 6G SSB according to the configuration information carried in 5G SIB1, and receive 6G SIB1 according to the MIB carried in the 6G SSB, thereby completing the initial access with the 6G cell.

[0212] In the above scheme, since 6G SSB and 6G SIB1 are sent based on the terminal's request, the goal of saving network energy consumption and reducing resource consumption can be achieved.

[0213] In some embodiments, 5G SIB1 can indicate whether the carrier of the 5G cell is a carrier that shares spectrum with the 6G cell. Since the 6G SSB may not exist on the carrier, the terminal will search for the SSB of the 5G cell on the carrier. Therefore, 5GSIB1 can indicate whether the carrier only has a 5G cell deployed, or whether both a 5G cell and a 6G cell are deployed. Thus, upon receiving 5GSIB1, the terminal can determine whether a 6G cell exists, and thereby determine whether to send the first request information.

[0214] For example, 5G SIB1 can explicitly indicate whether the carrier of a 5G cell is an MRSS carrier. For instance, 5G SIB1 can contain 1 bit of indication information. When this 1 bit is 0, it indicates that the carrier of the 5G cell is not an MRSS carrier, meaning that only a 5G cell is deployed on this carrier. When this 1 bit is 1, it indicates that the carrier of the 5G cell is an MRSS carrier, meaning that both 5G and 6G cells are deployed on this carrier.

[0215] For example, 5G SIB1 can implicitly indicate whether the carrier of a 5G cell is an MRSS carrier. For instance, if the first resource information is included in 5G SIB1, it indicates that the carrier is an MRSS carrier, meaning that both 5G and 6G cells are deployed on that carrier. Conversely, if the first resource information is not included in 5G SIB1, it indicates that the carrier is not an MRSS carrier, meaning that only 5G cells are deployed on that carrier.

[0216] In some embodiments, the transmission beam information for 6G SIB1 / 6G SSB can be indicated by 5G SIB1 or predefined by the protocol. A 5G SSB cycle may transmit multiple SSBs, which form an SS burst. Multiple SSBs within an SS burst may be transmitted by different beams, each corresponding to different precoding. There is a one-to-one correspondence between the beams of 5G SIB1 and 5G SSB. Optionally, if the base station transmits 6G SSB, then there is a one-to-one correspondence between the beams of 6G SIB1 and 6G SSB, and a possible correspondence between the beams of 6G SSB and 5G SIB1 / 5G SSB. If the base station does not transmit 6G SSB, then a possible correspondence between the beams of 6G SIB1 and 5G SIB1 / 5G SIB1.

[0217] For example, the number of beams in 6G SIB1 / 6G SSB is the same as that in 5G SSB / 5G SIB1, and the beam direction of 6G SIB1 / 6G SSB corresponds one-to-one with the beam direction of 5G SSB / 5G SIB1.

[0218] For example, for the sake of coverage or network energy saving, the 6G SIB1 / 6G SSB beams may be more numerous and narrower, or fewer and wider, than the 5G SSB / 5G SIB1 beams. Currently, the 5G SSB / 5G SIB1 has 8 beams. 5G SIB1 can indicate the correspondence between the 6G SIB1 / 6G SSB beams and the 5G SSB / 5G SIB1 beams. For instance, one 5G SSB / 5G SIB1 beam corresponds to m 6G SSB beams; when m is greater than 1, the 6G SIB1 / 6G SSB has more beams than the 5G SSB / 5G SIB1. For example, n 5G SSB / 5G SIB1 beams correspond to one 6G SIB1 / 6G SSB beam. When n is greater than 1, the 6G SIB1 / 6G SSB beams are fewer than the 5G SSB / 5G SIB1 beams.

[0219] It should be noted that m and n are both positive integers.
