System information needs to be transmitted in different beam directions to ensure that terminals located in different beams within the cell can receive the system information. After the number of beams in the NTN cell is increased, how to timely transmit the system information is a technical problem to be solved at present. SUMMARY

[0038] Alternatively,
[0039] The first MO is used for scheduling the second SI message, and the second MO is used for scheduling the second SI message; that is, the multiple MOs can repeatedly send the same second SI message, so that after the terminal receives multiple second SI messages, the multiple first SI messages can be combined to improve the success rate and accuracy of the reception of system information.

[0083] In order to better understand the embodiments of the present application, first, the system architecture related to the embodiments of the present application will be introduced as follows:
[0084] FIG. 1 is a schematic diagram of an architecture of a communication system 10 according to an embodiment of the present application. As shown in FIG. 1, the communication system 10 includes a radio access network (RAN) 100, wherein the RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1, collectively referred to as 110), and can further include at least one terminal (e.g., 120a-120j in FIG. 1, collectively referred to as 120). The RAN 100 can further include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1). The terminals 120 are connected to the RAN nodes 110 in a wireless manner. Terminals and terminals, and RAN nodes and RAN nodes can be connected to each other in a wired or wireless manner. The communication system 10 can further include a core network 200. The RAN nodes 110 are connected to the core network 200 in a wireless or wired manner. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrated with the logical functions of the core network devices and the logical functions of the RAN nodes. The communication system 10 can further include a data network (DN) 300.
[0085] The RAN 100 can be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, a future communication network defined in the 3rd generation partnership project (3GPP). The RAN 100 can also include two or more different wireless access systems described above. The RAN 100 can also be an open RAN (O-RAN). The RAN can also be referred to as an access network (AN).
[0086] The RAN node, also referred to as a radio access network device, an access network device, a RAN entity, or an access node, is configured to help terminals to access the communication system through wireless means. In one application scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next generation base station in a future communication network, a base station in a future mobile communication system. The RAN node can be a macro base station (such as 110a in FIG. 1), or a micro base station or an indoor station (such as 110b in FIG. 1), or a relay node or a donor node.
[0087] In another application scenario, wireless access can be achieved for a terminal through cooperation of multiple RAN nodes, and different RAN nodes respectively implement part of functions of a 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 implements functions of a radio resource control protocol and a packet data convergence protocol (PDCP) of a base station, and can also implement a function of a service data adaptation protocol (SDAP); the DU implements functions of a radio link control layer and a medium access control (MAC) layer of a base station, and can also implement part of a physical layer or all of a physical layer; and specific descriptions about the protocol layers can refer to related technical specifications of 3GPP. The RU can be used to implement functions of transceiving a radio frequency signal. The CU and the DU can be two independent RAN nodes, or can be integrated in a same RAN node, for example, integrated in a baseband unit (BBU). The RU can be included in a radio frequency device, for example, included 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.
[0088] In different systems, the RAN node can have different names. For example, in an O-RAN system, the CU can be referred to as an open CU (O-CU), the DU can be referred to as an open DU (O-DU), and the RU can be referred to as an open RU (O-RU). The RAN node in the embodiments of the present application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. For example, the RAN node can be a server loaded with a corresponding software module. The embodiments of the present application do not limit specific technologies and specific device forms adopted by the RAN node. For ease of description, a base station is described as an example of the RAN node in the following.
[0089] A terminal is a device with wireless transceiver function, which can send signals to a base station or receive signals from a base station. A terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. A terminal can be widely applied 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, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, airplane, ship, robot, mechanical arm, smart home device, etc. Embodiments of the present application do not limit the specific technology and specific device form of the terminal.
[0090] A base station and a terminal can be in a fixed position or movable. A base station and a terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water surface; can also be deployed on an airplane, balloon and artificial satellite. Embodiments of the present application do not limit the application scenarios of a base station and a terminal.
[0091] The roles of a base station and a terminal can be relative, for example, the helicopter or drone 120i in FIG. 1 can be configured as a mobile base station, which is a base station for those terminals 120j accessing to the wireless access network 100 through 120i; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate with each other through a wireless air interface protocol. Of course, 110a and 120i can also communicate with each other through a base station-to-base station interface protocol, in which case, 120i is also a base station relative to 110a. Therefore, a base station and a terminal can be collectively referred to as a communication apparatus, 110a and 110b in FIG. 1 can be referred to as a communication apparatus with base station function, and 120a-120j in FIG. 1 can be referred to as a communication apparatus with terminal function.
[0092] A base station and a terminal, a base station and a base station, a terminal and a terminal can communicate through licensed spectrum, can also communicate through unlicensed spectrum, and can also communicate through both licensed spectrum and unlicensed spectrum; can communicate through spectrum below 6 gigahertz (GHz), can also communicate through spectrum above 6 GHz, and can also communicate through both spectrum below 6 GHz and spectrum above 6 GHz. Embodiments of the present application do not limit the spectrum resources used for wireless communication.
[0093] In the embodiments of the present application, the functions of the base station can also be performed by a module (such as a chip) in the base station, or by a control subsystem containing the functions of the base station. The control subsystem containing the functions of the base station herein can be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal can also be performed by a module (such as a chip or modem) in the terminal, or by a device containing the functions of the terminal.
[0094] In the present application, the base station sends a downlink signal or downlink information to the terminal, and the downlink information is carried on a downlink channel; the terminal sends an uplink signal or uplink information to the base station, and the uplink information is carried on an uplink channel. In order to communicate with the base station, the terminal needs to establish a wireless connection on a cell controlled by the base station. The cell with which the terminal establishes a wireless connection is called the service cell of the terminal. When the terminal communicates with the service cell, it will also be interfered by signals from neighboring cells.
[0095] In the embodiments of the present application, the time domain symbol can be an orthogonal frequency division multiplexing (OFDM) symbol or a Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) symbol. If not specified, the symbol in the embodiments of the present application refers to a time domain symbol.
[0096] It can be understood that, in the embodiments of the present application, the physical downlink shared channel (PDSCH) and the PDCCH are only examples of the downlink data channel and the downlink control channel, respectively. In different systems and different scenarios, the data channel and the control channel can have different names, and the embodiments of the present application do not limit this.
[0097] The following explains some terms involved in the embodiments of the present application to facilitate understanding by those skilled in the art. This part is only for understanding and cannot be regarded as a disclosure or specific limitation of the technical solutions of the present application.
[0098] I. NTN
[0099] The scheme described in the embodiments of the present application can be applied to NTN. NTN, i.e., non-terrestrial network, is a general term for networks involving flying objects. NTN includes HAPS, satellite communication network and air-to-ground network. Key value scenarios of NTN mainly include poor terrestrial coverage areas, ocean communication, public safety needs, inter-aircraft communication, railways, etc., aiming to provide mobile broadband services for users.
[0100] HAPS is carried on an airborne platform. The airborne platform mainly includes an airplane, a balloon and an airship. HAPS uses the high-altitude platform station as a mobile communication access network device (such as a base station) to provide mobile services using the same frequency band as the ground mobile network.
[0101] The satellite communication network relies on a spaceborne platform and mainly includes low earth orbiting (LEO) satellites, medium earth orbiting (MEO) satellites and geostationary earth orbiting (GEO) satellites. According to the relationship between the satellite and the access network device, it can be divided into the following two architectures.
[0102] One is a transparent payload, in which the satellite is only responsible for signal forwarding and has no data processing capability. The access network device is located on the ground, and the satellite is connected to the access network device through the gateway on the ground. The signal between the terminal and the access network device is transmitted through the satellite, and the data processing function is still located at the access network device. The link between the satellite and the terminal is called a service link, and the link between the satellite and the access network device is called a feeder link. For example, the transparent architecture can be as shown in FIG. 2.
[0103] The other is a regenerative payload, in which the satellite has all or part of the functions of the access network device, i.e., the satellite can perform data processing. Specifically, it can be divided into multiple forms such as the complete access network device being located on the satellite, the distributed unit (DU) of the access network device being located on the satellite, and the centralized unit (CU) of the access network device being located on the ground. The link between the satellite / access network device and the UE is called a service link. For example, the regenerative architecture can be as shown in FIG. 3.
[0104] According to the movement of the NTN cell in the ground coverage area, the NTN cell can be divided into the following three categories:
[0105] 1) Earth-fixed: The coverage area of this type of NTN cell is fixed to a certain area on the ground, i.e., persistent point coverage. Geostationary Earth Orbiting (GEO) satellites can provide this type of NTN cell.
[0106] 2) Quasi-earth-fixed: The coverage area of this type of NTN cell is fixed to a certain area on the ground for a period of time, and will be changed to another area on the ground after a period of time, i.e., point coverage for a period of time. Low Earth Orbiting (LEO) satellites and Medium Earth Orbiting (MEO) satellites can provide this type of NTN cell. For example, a quasi-earth-fixed NTN cell can be as shown in FIG. 4.
[0107] 3) Earth-moving: The coverage area of this type of NTN cell slides on the ground. LEO satellites and MEO satellites can provide this type of NTN cell. For example, an earth-moving NTN cell can be as shown in FIG. 5.
[0108] II. Beam
[0109] Beamforming technology is introduced in 5G NR, and access network devices use a number of beams to sequentially sweep different areas in a cell to achieve complete coverage of a cell. Each beam has a corresponding identifier (beam index) for uniquely determining the beam. As shown in FIG. 6, assuming there are 8 beams in a cell, the access network device transmits beam 0 in direction 1 at time t1, transmits beam 1 in direction 2 at time t2, and so on, to form complete cell coverage by the 8 beams.
[0110] The reference signal of the beam can be SSB or channel state information-reference signal (CSI-RS). Taking SSB as an example, there are 8 SSBs (SSB0-SSB7) in the cell in FIG. 6, and the access network device will periodically transmit the 8 SSBs in different directions in time.
[0111] III. Beam expansion
[0112] The number of beams in an NTN cell is affected by the satellite coverage area requirement and the satellite beam size, and can be increased compared to a terrestrial cell. For example, for frequency range FR1, the maximum number of beams in a terrestrial cell is 8; but in the NTN scenario, the coverage area of one NTN cell can need to reach the order of hundreds of thousands of square kilometers, and the diameter of a satellite beam is relatively limited (e.g., 50-60 km in diameter), i.e., the area covered by one beam is limited. Therefore, the number of beams in one NTN cell will likely be much larger than the number of beams in a terrestrial cell. For example, it can reach 128 / 256 / 512, etc.
[0113] One way to expand the number of beams in a cell is to expand the period of the synchronization signal block (SSB). For example, the access network device sends SSBs in different directions in different 20ms in a period, a number of SSBs in one 20ms can be referred to as an SSB burst set, a total of N 20ms (i.e., N SSB bursts) are sent, and the period of the SSB is expanded to (N*20ms) to achieve an increase in the number of scanned beams. For example, as shown in FIG. 7, assuming that the SSB period is 640ms, and the mode of sending 8 different SSBs every 20ms is used, a total of 640 / 20 = 32 20ms are sent, and the number of SSBs in one NTN cell is increased to 32*8 = 256.
[0114] Four, system information
[0115] System information is a message sent by an access network device, which contains information required for terminal initialization and some other function / feature related information. For example, system information can be divided into minimum system information and other system information. Among them:
[0116] The minimum system information can be composed of a master information block (MIB) and a SIB1, which is also referred to as (remaining minimum SI, RMSI). The MIB is periodically broadcast on the broadcast channel (BCH). The SIB1 is periodically broadcast on the downlink shared channel (DL-SCH), or sent to the terminal in the radio resource control (RRC) connected state (RRC_CONNECTED) through dedicated signaling.
[0117] Other system information consists of other SIBs, e.g., SIB2-SIB25, etc. Other SIBs are periodically broadcast on the DL-SCH or broadcast on-demand on the DL-SCH. For example, when a terminal in RRC idle state (RRC_IDLE) or RRC inactive state (RRC_INACTIVE) requests a certain SIB, the network broadcasts the SIB, otherwise the SIB is not transmitted. Or other SIBs are transmitted to terminals in RRC connected state through dedicated signaling.
[0118] Under different systems, system information can have different specific settings. In addition to MIB and SIB1, minimum system information can also have other SIBs, and other system information can also have other SIBs. The embodiments of the present application do not limit which SIBs are included in the specific minimum system information and other system information.
[0119] The basic flow of a terminal in RRC idle state or RRC inactive state acquiring system information is that the terminal first acquires MIB, acquires SIB1 according to the scheduling information in MIB, and acquires other SIBs according to the scheduling information in SIB1.
[0120] Five, system information scheduling (SI scheduling)
[0121] The access network device transmits scheduling information of system information in SIB1, which is used by the terminal to determine the scheduling occasion (also referred to as system information window, SI window) of other SIBs in addition to SIB1, i.e., after receiving SIB1, the terminal can receive other SIBs according to the scheduling information of system information. The specific mechanism is as follows:
[0122] One or more other SIBs constitute a system information message (SI message). The transmission period of SIBs contained in a SI message is the same, i.e., the transmission period of the SI message. The transmission periods of different SI messages can be the same or different. For example, as shown in FIG. 8, SI message 1 includes SIB2 and SIB5, and SI message 2 includes SIB3, SIB4, and SIBX.
[0123] The access network device schedules in the granularity of SI message. The scheduling information of system information in SIB1 can include the following information:
[0124] 1) Scheduling information list, which includes the scheduling information of one or more SI messages. The scheduling information of a SI message includes SIB mapping information, which indicates which SIB or which SIBs are contained in the SI message. That is, the scheduling information of a SI message is used to configure the SI message.
[0125] 2) Configuration information of system information window.
[0126] 3) Other information. For example, configuration information for terminal to request access network device to send system information, area information to which system information belongs, and the like.
[0127] Six, scheduling information list
[0128] Due to the evolution of standards, 3GPP standards successively define different SIBs in different versions, which contain information related to different functions or features. In addition, the standards also define different SI scheduling information lists to configure the SI messages corresponding to these different SIBs. For example, SIBs of Release 15 / Release 16 non-positioning features, SIBs of Release 17 / Release 18, and posSIBs (SIBs of positioning features) of R16 are configured to form SI messages through the following three different SI scheduling information lists, respectively. Among them:
[0129] 1) R15 scheduling information list, used to configure SI messages composed of SIBs of R15 / R16 non-positioning features.
[0130] 2) R17 scheduling information list, used to configure SI messages composed of SIBs of R17 / R18 non-positioning features, and / or SI messages composed of SIBs of R17 / R18 positioning features.
[0131] 3) R16 positioning feature scheduling information list, used to configure SI messages composed of SIBs of R16 positioning features.
[0132] In the scenario where the SSB period is extended, take the example of sending SSBs in different directions in each 20 ms. System information needs to be sent on each direction of SSB to ensure that terminals located in different beams of the cell can receive system information. For example, assuming that an SSB burst in each 20 ms contains 8 SSBs, system information needs to be sent in 8 SSB directions. If the sending of one SI message needs to use 1 scheduling unit (for example, 1 slot), the sending of 8 SSB directions needs to use 8 scheduling units, and the case of multiple SI messages will be extrapolated in this way. For example, as shown in FIG. 9, for SI message 1, the access network device sends in 8 SSB directions in turn, which needs 8 scheduling units, that is, the scheduling occasion of SI message 1 includes 8 scheduling units. For SI message 2, the access network device sends in 8 SSB directions in turn, which also needs 8 scheduling units, that is, the scheduling occasion of SI message 2 includes 8 scheduling units. Since the resources in 20 ms are limited, when the number of SI messages is large, the scheduling units required for the sending of SI messages are also large, and it will not be possible to complete the sending of system information in each SSB direction in this 20 ms. For example, the unsent SI messages are sent at other times outside this 20 ms, resulting in untimely sending of system information.
[0133] In order to be able to send system information in time, the embodiment of the present application provides a communication method and a communication device.
[0134] The communication method and the communication device will be further described below with reference to the drawings. It can be understood that the terminal and the access network device are taken as an example of the execution subject of the interaction in the present application, but the present application does not limit the execution subject of the interaction. For example, the method executed by the terminal in the present application can also be implemented by a communication / processing module or a circuit or a chip responsible for communication / processing function in the terminal, or a logic node, a logic module or software capable of realizing all or part of the terminal function. The method executed by the access network device in the present application can also be implemented by a module (such as a circuit, a chip or a chip system, etc.) in the access network device, or a logic node, a logic module or software capable of realizing all or part of the function of the access network device.
[0135] Please refer to FIG. 10, which is a flowchart of a communication method provided by an embodiment of the present application, wherein:
[0136] 1001. The access network device sends a first scheduling information list and a second scheduling information list, the first scheduling information list is configured with a first SI message, the second scheduling information list is configured with a second SI message, and the content in the first SI message and the content in the second SI message are carried in a same SI message. Correspondingly, the terminal can receive the first scheduling information list and the second scheduling information list.
[0137] In the embodiments of the present application, the scheduling information list can also be referred to as an SI scheduling list or an SI scheduling information list, and the like, and the embodiments of the present application do not make any limitation.
[0138] In a possible embodiment, the first scheduling information list is an R17 scheduling information list, and the second scheduling information list is an R15 scheduling information list or an R16 positioning scheduling information list. Alternatively, the first scheduling information list can also be an R15 scheduling information list, and the second scheduling information list is an R16 positioning scheduling information list. Alternatively, the first scheduling information list and the second scheduling information list can also be scheduling information lists of other versions, and the embodiments of the present application do not make any limitation.
[0139] In a possible embodiment, the first scheduling information list and the second scheduling information list can be located in the SIB1.
[0140] In the embodiments of the present application, the first scheduling information list is configured with a first SI message, and the second scheduling information list is configured with a second SI message. It can also be understood that the first scheduling information list schedules the first SI message, and the second scheduling information list schedules the second SI message. Alternatively, the first scheduling information list includes scheduling information of the first SI message, and the second scheduling information list includes scheduling information of the second SI message.
[0141] In a possible embodiment, in addition to the first SI message, the first scheduling information list can also be configured with other SI messages. In addition to the second SI message, the second scheduling information list can also be configured with other SI messages.
[0142] In the embodiments of the present application, the content in the first SI message and the content in the second SI message are carried in the same SI message. It can also be understood that the content in the first SI message and the content in the second SI message are transmitted in the same resource, or the content in the first SI message and the content in the second SI message are transmitted in the same signaling, or the first SI message and the second SI message are combined into the same SI message, or the first SI message and the second SI message are regarded as the same SI message. Optionally, the content in the first SI message is another SIB. The content in the second SI message is another SIB. The other SIB can also be understood as a SIB other than the SIB1. For example, the other SIB includes SIB2-SIB25, and the like.
[0143] For example, the R17 scheduling information list is configured with an SI message 1 and an SI message 2. The R15 scheduling information list is configured with an SI message 3. The R16 positioning scheduling information list is configured with an SI message 4. The content in the SI message 1 and the content in the SI message 3 are carried in the same SI message. The content in the SI message 2 and the content in the SI message 4 are carried in the same SI message.
[0144] Optionally, the content of more than two SI messages can be carried in the same SI message. Optionally, the content of more than two SI messages in the scheduling information list can be carried in the same SI message.
[0145] For example, SI message 1, SI message 2 and SI message 3 are configured in the R17 scheduling information list. SI message 4 is configured in the R15 scheduling information list. SI message 5 and SI message 6 are configured in the R16 positioning scheduling information list. The content in SI message 1, the content in SI message 4 and the content in SI message 5 are carried in the same SI message. The content in SI message 2, the content in SI message 3 and the content in SI message 6 are carried in the same SI message.
[0146] In a possible embodiment, the first SI message is an SI message of a first characteristic, and the second SI message is an SI message of the first characteristic. Alternatively, the first SI message is an SI message of a first characteristic, and the SI message configured in the second scheduling information list is an SI message of the first characteristic. Optionally, the first characteristic is a positioning characteristic or a non-positioning characteristic. In the embodiments of the present application, the characteristic of the SI message can be referred to as a function, a mechanism, etc. In the embodiments, the characteristic is taken as an example for description. That is, the content in the SI messages of the same characteristic in the first scheduling information list and the second scheduling information list can be carried in the same SI message. In the existing scheduling mechanism, the SI messages of different characteristics are scheduled separately. By carrying the content in the SI messages of the same characteristic in the same SI message, the SI messages of the same characteristic can be scheduled together, and the compatibility with the existing scheduling mechanism can be better. Of course, the content in the SI messages of different characteristics can also be carried in the same SI message, which is not limited in the embodiments of the present application.
[0147] For example, SI message 1 and SI message 2 are configured in the R17 scheduling information list. SI message 1 is an SI message of a positioning characteristic, and SI message 2 is an SI message of a non-positioning characteristic. SI message 3 of a non-positioning characteristic is configured in the R15 scheduling information list. SI message 4 of a positioning characteristic is configured in the R16 positioning scheduling information list. The content in SI message 1 and the content in SI message 3 are carried in the same SI message. The content in SI message 2 and the content in SI message 4 are carried in the same SI message.
[0148] The following describes several possible ways of how to determine that the content in the first SI message and the content in the second SI message are carried in the same SI message:
[0149] Manner one: the access network device sends indication information to the terminal, the indication information indicates that the content in the first SI message and the content in the second SI message are carried in the same SI message. Correspondingly, the terminal can receive the indication information. Optionally, the indication information can also be called indication information or indication field, etc., and the embodiment is illustrated by taking the indication information as an example.
[0150] That is, the access network device can indicate through signaling which SI message in the first scheduling information list and which SI message in the second scheduling information list are carried in the same SI message. Based on manner one, it can be more flexible to indicate which SI message is carried in the same SI message by indicating.
[0151] The following describes two possible implementation manners of the indication information:
[0152] 1) The indication information corresponds to the first SI message, and the indication information indicates the second SI message. That is, the SI message in the first scheduling information list has a corresponding relationship with the indication information, and the indication information is used to indicate which SI message in the second scheduling information list carries the content of the corresponding SI message in the same SI message, so that it can be more flexible to indicate which SI message is carried in the same SI message by indicating. Optionally, the indication information can be located in the first scheduling information list. Optionally, the indication information can indicate the second SI message by indicating the index of the second SI message. The index of the SI message can also be called identification, label, etc.
[0153] For example, it is assumed that the first scheduling information list is the R17 scheduling information list, and the second scheduling information list is the R15 scheduling information list. The first scheduling information list is configured with SI message 1 and SI message 2. The SI message 1 corresponds to the indication information 1, and the indication information 1 indicates the index 3. The content in the SI message 1 is carried in the same SI message as the content in the third SI message in the R15 scheduling information list. The SI message 2 corresponds to the indication information 2, and the indication information 2 indicates the index 5. The content in the SI message 2 is carried in the same SI message as the content in the fifth SI message in the R15 scheduling information list.
[0154] For example, assume that the first scheduling information list is an R17 scheduling information list and the second scheduling information list is an R15 scheduling information list. SI message 1, SI message 2, and SI message 3 are configured in the first scheduling information list. SI message 1 corresponds to indication information 1, and the indication information 1 indicates a sequence number 3. The content in SI message 1 is carried in the same SI message as the content in the third SI message configured in the R15 scheduling information list. SI message 2 corresponds to indication information 2, and the indication information 2 indicates a sequence number 5. SI message 3 corresponds to indication information 3, and the indication information 3 indicates a sequence number 5. The content in SI message 2 and the content in SI message 3 are carried in the same SI message as the content in the fifth SI message configured in the R15 scheduling information list.
[0155] Optionally, the content of the SI messages of the same type in the first scheduling information list and the second scheduling information list can be carried in the same SI message in combination with the characteristics of the SI messages and the indication information.
[0156] For example, assume that the first scheduling information list is an R17 scheduling information list, and the content of the SI messages of the same type is carried in the same SI message. Assume that SI message 1 and SI message 2 are configured in the R17 scheduling information list. SI message 1 is a non-positioning type SI message, and SI message 1 corresponds to indication information 1, and the indication information 1 indicates a sequence number 3. Since the SI message configured in the R15 scheduling information list is a non-positioning type SI message, the content in SI message 1 is carried in the same SI message as the content in the third SI message configured in the R15 scheduling information list.
[0157] SI message 2 is a positioning type SI message, and SI message 2 corresponds to indication information 2, and the indication information 2 indicates a sequence number 3. Since the SI message configured in the R16 positioning scheduling information list is a positioning type SI message, the content in SI message 2 is carried in the same SI message as the content in the third SI message configured in the R16 positioning scheduling information list.
[0158] Optionally, some SI messages in the first scheduling information list can also have no corresponding indication information. If a certain SI message in the first scheduling information list has no corresponding indication information or the corresponding indication information is a default value / special value, it can be considered that the content in the SI message is not carried in the same SI message as the content in other SI messages. Alternatively, all SI messages in the first scheduling information list have corresponding indication information, which is not limited by the embodiments of the present application.
[0159] 2) The indication information completely indicates which SI message in the first scheduling information list and which SI message in the second scheduling information list are carried in the same SI message.
[0160] The indication information can indicate which SI message in the second scheduling information list carries the content of the multiple SI messages in the first scheduling information list respectively.
[0161] For example, the indication information indicates that the content in the first SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the first SI message configured in the R15 scheduling information list, that the content in the second SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the second SI message configured in the R15 scheduling information list, and that the content in the third SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the first SI message configured in the R16 positioning scheduling information list.
[0162] In a possible embodiment, the scheduling occasion of the same SI message is the scheduling occasion of the first SI message or the second SI message. Alternatively, the scheduling occasion is an SI window or a time period in the SI window.
[0163] Option 2: The content in the SI message configured in the first scheduling information list and the content in the SI message configured in the second scheduling information list are carried in the same SI message in order. This scheme of carrying the content of multiple SI messages in the same SI message in order is simple, and does not need to introduce complex indication information to achieve carrying the content of multiple SI messages in the same SI message, thereby reducing the operation complexity and being conducive to saving signaling overhead. Alternatively, there are two order combinations of carrying modes as follows.
[0164] 1) The first SI message is an SI message of a first characteristic, and the order of the first SI message in the first characteristic SI message configured in the first scheduling information list is the same as the order of the second SI message in the first characteristic SI message configured in the second scheduling information list.
[0165] That is, the content in the multiple SI messages can be carried in the same SI message in combination with the characteristics and orders of the SI messages. Alternatively, the SI message configured in the second scheduling information list is an SI message of a first characteristic.
[0166] For example, assume that the first SI message configured in the R17 scheduling information list is a non-positioning-specific SI message, the second is a positioning-specific SI message, and the third is a non-positioning-specific SI message. Since the SI message configured in the R15 scheduling information list is a non-positioning-specific SI message, and the SI message configured in the R16 positioning scheduling information list is a positioning-specific SI message. Therefore, the content in the first SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the first SI message configured in the R15 scheduling information list; the content in the second SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the first SI message configured in the R16 positioning scheduling information list; and the content in the third SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the second SI message configured in the R15 scheduling information list.
[0167] 2) The order of the first SI message in the first scheduling information list is the same as the order of the second SI message in the second scheduling information list.
[0168] That is, the content in the multiple SI messages is carried in the same SI message directly according to the order of the SI messages.
[0169] For example, the content in the first SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the first SI message configured in the R15 scheduling information list; the content in the second SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the second SI message configured in the R15 scheduling information list; and so on.
[0170] For example, the content in the first SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the first SI message configured in the R16 positioning scheduling information list; the content in the second SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the second SI message configured in the R16 positioning scheduling information list; and so on.
[0171] The above examples are described by taking the order as the sequence, but are not limited to the sequence, and can also be other orders such as the reverse sequence.
[0172] For example, taking the case of carrying the content in multiple SI messages in the same SI message in combination with the characteristics and order of SI messages. It is assumed that the first SI message configured in the R17 scheduling information list is a non-positioning characteristic SI message, the second is a positioning characteristic SI message, and the third is a non-positioning characteristic SI message. The content in the first SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the last SI message configured in the R15 scheduling information list; the content in the second SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the last SI message configured in the R16 positioning scheduling information list; and the content in the third SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the last SI message configured in the R15 scheduling information list.
[0173] For another example, taking the case of carrying the content in multiple SI messages in the same SI message directly according to the order. The content in the first SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the last SI message configured in the R15 scheduling information list; the content in the second SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the last SI message configured in the R15 scheduling information list, and so on.
[0174] Alternatively, the content in the first SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the last SI message configured in the R16 positioning scheduling information list; the content in the second SI message configured in the R17 scheduling information list is carried in the same SI message as the content in the last SI message configured in the R16 positioning scheduling information list, and so on.
[0175] In a possible embodiment, the access network device can further send first information to the terminal, where the first information indicates that the content in the SI message configured in the first scheduling information list and the content in the SI message configured in the second scheduling information list are carried in the same SI message according to the order. Accordingly, the terminal can receive the first information.
[0176] That is, the access network device can indicate whether to carry the content in multiple SI messages in the same SI message in the order combination carrying mode. That is, the first information is equivalent to a switch for turning on the function of carrying the content in multiple SI messages in the same SI message in the order combination carrying mode. Based on this possible embodiment, it is beneficial to meet different communication requirements.
[0177] In a possible embodiment, the access network device can further send, to the terminal, second information indicating that the content in the SI message of the first scheduling information list configuration and the content in the SI message of the second scheduling information list configuration are carried in the same SI message according to a first rule or a second rule; the first rule is the order of the SI message of the first characteristic of the first scheduling information list configuration in the SI message of the first characteristic of the first scheduling information list configuration and the order of the SI message of the first characteristic of the second scheduling information list configuration in the SI message of the first characteristic of the second scheduling information list configuration; and the second rule is the order of the SI message of the first scheduling information list configuration in the SI message of the first scheduling information list configuration and the order of the SI message of the second scheduling information list configuration in the SI message of the second scheduling information list configuration. Accordingly, the terminal can receive the second information.
[0178] In the second information, the content in the SI message of the first scheduling information list configuration and the content in the SI message of the second scheduling information list configuration can be carried in the same SI message according to the first rule or the second rule, which can also be understood as: the content in the SI message of the first characteristic of the first scheduling information list configuration and the content in the SI message of the first characteristic of the second scheduling information list configuration are carried in the same SI message according to the order of the SI message of the first characteristic of the first scheduling information list configuration in the SI message of the first characteristic of the first scheduling information list configuration and the order of the SI message of the first characteristic of the second scheduling information list configuration in the SI message of the first characteristic of the second scheduling information list configuration; or the content in the SI message of the first scheduling information list configuration and the content in the SI message of the second scheduling information list configuration are carried in the same SI message according to the order of the SI message of the first scheduling information list configuration in the SI message of the first scheduling information list configuration and the order of the SI message of the second scheduling information list configuration in the SI message of the second scheduling information list configuration. That is, the second information indicates whether the content in the multiple SI messages is carried in the same SI message according to the above order combination carrying manner 1) or the order combination carrying manner 2). Alternatively, the second information can also indicate whether the content in the multiple SI messages is carried in the same SI message according to the sequence combination or the reverse sequence combination. Based on the possible embodiment, the carrying manner of the content in the multiple SI messages can be more flexible.
[0179] In another possible embodiment, the content in the SI message of the first scheduling information list configuration and the content in the SI message of the second scheduling information list configuration are carried in the same SI message according to the first rule or the second rule, which can be preconfigured, predefined, or specified by a protocol. That is, the access network device does not need to use the second information to notify the terminal of the combination carrying according to what, which is beneficial to saving signaling overhead.
[0180] In a possible implementation, the scheduling occasion of the same SI message is the scheduling occasion of the first SI message or the second SI message. Optionally, the scheduling occasion is an SI window or a time period in an SI window.
[0181] Option 3: The scheduling occasion of the first SI message is the same as the scheduling occasion of the second SI message.
[0182] That is, which contents in which SI messages are carried in the same SI message can be implicitly indicated by the scheduling occasion of the SI message. The scheme of implicitly indicating which contents in which SI messages are carried in the same SI message by the scheduling occasion of the SI message is simple and flexible, and can carry contents of multiple SI messages in the same SI message by using existing configuration parameters, thereby reducing operation complexity and facilitating saving signaling overhead. Optionally, the scheduling occasion is an SI window or a time period in an SI window.
[0183] For example, the access network device configures the scheduling occasion of the SI message configured in the R17 scheduling information list, and if the scheduling occasion is the same as the scheduling occasion corresponding to the SI message configured in the R15 scheduling information list, it indicates that the contents in the two SI messages are carried in the same SI message. If the scheduling occasion is the same as the scheduling occasion corresponding to the SI message configured in the R16 positioning scheduling information list, it indicates that the contents in the two SI messages are carried in the same SI message.
[0184] For another example, the access network device configures the scheduling occasion of the SI message configured in the R16 positioning scheduling information list, and if the scheduling occasion is the same as the scheduling occasion corresponding to the SI message configured in the R15 scheduling information list, it indicates that the contents in the two SI messages are carried in the same SI message. If the scheduling occasion is the same as the scheduling occasion corresponding to the SI message configured in the R17 scheduling information list, it indicates that the contents in the two SI messages are carried in the same SI message.
[0185] Optionally, the contents in the SI messages with the same characteristics and the same scheduling time in the first scheduling information list and the second scheduling information list can be carried in the same SI message in combination with the characteristics and the scheduling occasion of the SI message.
[0186] For example, the access network device configures a scheduling occasion of an SI message configured in the R17 scheduling information list, if the scheduling occasion is the same as a scheduling occasion corresponding to an SI message configured in the R15 scheduling information list, and the SI message in the R17 scheduling information list is an SI message that is not positioning-specific, it is indicated that the content in the two SI messages is carried in the same SI message. If the scheduling occasion is the same as a scheduling occasion corresponding to an SI message configured in the R16 positioning scheduling information list, and the SI message in the R17 scheduling information list is an SI message that is positioning-specific, it is indicated that the content in the two SI messages is carried in the same SI message.
[0187] In a possible embodiment, the access network device transmits the content in the first SI message and the content in the second SI message through the same SI message. Accordingly, the terminal receives the content in the first SI message and the content in the second SI message through the same SI message.
[0188] It can be seen that, based on the method described in FIG. 10, the content of multiple SI messages in different scheduling information lists can be carried in the same SI message, that is, the multiple SI messages in different scheduling information lists can be combined into one SI message. After the multiple SI messages are combined into one SI message, the multiple SI messages can use the same scheduling occasion, that is, share the same scheduling resource. In this way, the resources occupied by the transmission of system information can be reduced, the problem of insufficient resources in the case of independent scheduling of multiple SI messages can be solved, the system information can be transmitted in time, and the performance of the terminal using the corresponding function of the system information is improved or guaranteed.
[0189] Please refer to FIG. 11, which is a flowchart of another communication method provided by an embodiment of the present application, wherein:
[0190] 1101. The access network device transmits a first scheduling information list and a second scheduling information list, the first scheduling information list is configured with a first system information (SI) message, and the second scheduling information list is configured with a second SI message, the first SI message and the second SI message are configured with the same first scheduling occasion. Accordingly, the terminal can receive the first scheduling information list and the second scheduling information list.
[0191] In the embodiments of the present application, the scheduling information list can also be referred to as an SI scheduling list or an SI scheduling information list, and the like, which is not limited in the embodiments of the present application.
[0192] In a possible embodiment, the first scheduling information list is an R17 scheduling information list, and the second scheduling information list is an R15 scheduling information list or an R16 positioning scheduling information list. Alternatively, the first scheduling information list can also be an R15 scheduling information list, and the second scheduling information list can be an R16 positioning scheduling information list. Alternatively, the first scheduling information list and the second scheduling information list can also be scheduling information lists of other versions, which are not limited in the embodiments of the present application.
[0193] In a possible embodiment, the first scheduling information list and the second scheduling information list can be located in the SIB1.
[0194] In the embodiments of the present application, the first scheduling information list is configured with the first SI message, and the second scheduling information list is configured with the second SI message. It can also be understood that the first scheduling information list schedules the first SI message, and the second scheduling information list schedules the second SI message. Alternatively, the first scheduling information list includes scheduling information of the first SI message, and the second scheduling information list includes scheduling information of the second SI message.
[0195] In a possible embodiment, in addition to the first SI message, the first scheduling information list can also be configured with other SI messages. In addition to the second SI message, the second scheduling information list can also be configured with other SI messages. Alternatively, the scheduling occasions of the SI messages in two or more scheduling information lists can be the same.
[0196] In the embodiments of the present application, the first SI message and the second SI message are configured as the same first scheduling occasion, that is, the first SI message and the second SI message are configured as the same scheduling occasion. Optionally, the first scheduling occasion can also be referred to as a first SI window or a time period in the first SI window. Although the first SI message and the second SI message are configured as the same scheduling occasion, the content in the first SI message and the content in the second SI message can be carried in the same SI message or in different SI messages, which is not limited in the embodiments of the present application. The access network device can carry the content in the first SI message and the content in the second SI message in the same SI message or in different SI messages according to the communication requirement. For example, in the case of insufficient resources, the content of multiple SI messages can be carried in the same SI message, which can ensure the timeliness of the transmission of system information. For another example, in the case of sufficient resources, the content of multiple SI messages can be carried in different SI messages, because the transmission of different system information in different scheduling occasions does not affect each other, and therefore, the reliability is higher. For the description of the content in the first SI message and the content in the second SI message that can be carried in the same SI message, reference can be made to the description in the embodiments corresponding to FIG. 10, which is not repeated here. For the description of the content in the first SI message and the content in the second SI message, reference can be made to the description in the embodiments corresponding to FIG. 10, which is not repeated here.
[0197] In a possible embodiment, the first SI message is an SI message of a first characteristic, and the second SI message is an SI message of the first characteristic. That is, the multiple SI messages of the same characteristic in the first scheduling information list and the second scheduling information list are configured as the same scheduling occasion. Optionally, the first characteristic is a positioning characteristic or a non-positioning characteristic.
[0198] For example, the R17 scheduling information list is configured with SI message 1 and SI message 2. The SI message 1 is an SI message of a non-positioning characteristic. The SI message 2 is an SI message of a positioning characteristic. The SI message 3 configured by the R15 scheduling information list is configured as the same scheduling occasion 1 as the SI message 1. The SI message 4 configured by the R16 positioning scheduling information list is configured as the same scheduling occasion 2 as the SI message 2.
[0199] In a possible embodiment, the first scheduling occasion has one or more monitoring occasions (MOs) for scheduling SI messages. Optionally, in the first scheduling occasion, one SSB can be associated with one or more MOs.
[0200] In a possible embodiment, if the first scheduling occasion has one MO, the MO is used for scheduling the first SI message or the second SI message or a third SI message, and the content in the first SI message and the content in the second SI message are carried in the third SI message.
[0201] In a possible embodiment, if there are multiple MOs in the first scheduling occasion. In the embodiments of the present application, it is not limited whether the SI messages scheduled on the multiple MOs are the same.
[0202] Optionally, the multiple MOs at least include a first MO and a second MO. For example, one SSB is associated with the first MO and the second MO. The first MO and the second MO have the following scheduling conditions:
[0203] 1) The first MO is used to schedule a first SI message, and the second MO is used to schedule the first SI message.
[0204] That is, the multiple MOs can repeatedly send the same first SI message, so that after the terminal receives multiple first SI messages, the multiple first SI messages can be combined to improve the success rate and accuracy of receiving system information.
[0205] 2) The first MO is used to schedule a second SI message, and the second MO is used to schedule the second SI message.
[0206] That is, the multiple MOs can repeatedly send the same second SI message, so that after the terminal receives multiple second SI messages, the multiple first SI messages can be combined to improve the success rate and accuracy of receiving system information.
[0207] 3) The first MO is used to schedule a third SI message, the content in the first SI message and the content in the second SI message are carried in the third SI message, and the second MO is used to schedule the first SI message or the second SI message or the third SI message.
[0208] For another example, the first MO is used to schedule a third SI message, and the second MO is used to schedule a first SI message. For another example, the first MO is used to schedule a third SI message, and the second MO is used to schedule a second SI message. For example, the first MO is used to schedule a third SI message, and the second MO is used to schedule the third SI message.
[0209] That is, the multiple MOs can repeatedly send the same SIB, so that after the terminal receives multiple same SIBs, the multiple same SIBs can be combined to improve the success rate and accuracy of receiving system information. And by carrying the content of multiple SI messages in the same SI message, the timeliness of sending system information can be ensured.
[0210] 4) The first MO is used to schedule a first SI message, and the second MO is used to schedule a second SI message.
[0211] That is, multiple MOs can also schedule different SI messages, different SI messages are scheduled by different MOs, because the transmission of different system information does not affect each other when independently scheduled, therefore, it has higher reliability.
[0212] In one possible embodiment, the terminal detects the first scheduling occasion until receiving the SI message corresponding to the first scheduling occasion, or until receiving the SIB corresponding to the first scheduling occasion, or until receiving the SI message that can occur in the first scheduling occasion, or until receiving the SIB that can occur in the first scheduling occasion, or until detecting the first scheduling occasion.
[0213] For example, the terminal detects the first scheduling occasion, if all SI messages corresponding to the first scheduling occasion are received in the first scheduling occasion, the terminal stops detecting. If all SI messages corresponding to the first scheduling occasion are not received in the first scheduling occasion, the terminal continues to detect until the first scheduling occasion is detected.
[0214] For another example, the terminal detects the first scheduling occasion, whether all SI messages corresponding to the first scheduling occasion are received in the first scheduling occasion or not, the terminal continues to detect until the first scheduling occasion is detected.
[0215] For example, as shown in FIG. 12, it is assumed that there are 8 SSBs (0-7). There are 18 physical downlink control channel (PDCCH) detection occasions MO in one scheduling occasion, i.e. MO1-MO8 correspond to SSB0-SSB7 respectively, MO9-MO16 correspond to SSB0-SSB7 respectively, MO17 corresponds to SSB0, and MO18 corresponds to SSB1. It is assumed that SI message 1 configured in the R17 scheduling information list contains SIB19, SI message 2 configured in the R15 scheduling information list contains SIB2, and SI message 1 and SI message 2 are configured in the same scheduling occasion. The terminal detects the MO corresponding to SSB0.
[0216] For example, if the terminal receives SIB19 contained in SI message 1 in MO1, the terminal still needs to detect MO9 and / or MO17 so that the terminal receives SIB2 contained in SI message 2. In one case, the terminal stops detecting when receiving SIB19 and SIB2. In another case, the terminal continues to detect until the end of the scheduling occasion when receiving SIB19 and SIB2 if the scheduling occasion has not ended.
[0217] In particular, it is not limited whether the SI message transmitted on MO9 / MO17 is the same as that transmitted on MO1. For example, the SI message 1 transmitted on MO1 can be repeatedly transmitted on MO9, or the SI message 2 including SIB2 can be transmitted on MO9, or the SI message including SIB19 can be transmitted on MO9.
[0218] For another example, the terminal receives an SI message on MO1, which includes SIB19 and SIB2. In one case, the terminal can stop detecting the subsequent MO. In another case, the detection of MO9 and MO17 can be optionally continued until the end of the scheduling occasion.
[0219] In particular, it is not limited whether the SI message transmitted on MO9 / MO17 is the same as that transmitted on MO1. For example, the SI message 1 transmitted on MO1 can be repeatedly transmitted on MO9, or the SI message 2 including SIB2 can be transmitted on MO9, or the SI message including SIB19 can be transmitted on MO9.
[0220] Optionally, if the first MO is used to schedule the third SI message and the second MO is used to schedule the third SI message, the UE can continue to detect after receiving the third SI message on the first MO and combine the third SI message received multiple times. That is, if the SI message scheduled on the previous MO includes all the SI messages or SIBs that can appear in the scheduling occasion, the SI message scheduled on the next MO is the same as the previous SI message, and the terminal can continue to receive the SI message after receiving the SI message once and combine the same SI message received.
[0221] For example, the terminal receives an SI message on MO1, which includes SIB19 and SIB2. It can be specified that the SI message transmitted on MO9 / MO17 is the same as that transmitted on MO1. If the terminal continues to detect MO9 / MO17, the terminal can combine the SI messages received on MO1 / MO9 / MO17 to improve the success rate and accuracy of receiving system information.
[0222] It can be seen that, based on the method described in FIG. 11, multiple pieces of SI messages in different scheduling information lists can use the same scheduling occasion, that is, share the same scheduling resource. That is, the contents of multiple pieces of SI messages can be sent in the same scheduling occasion. For example, one scheduling occasion can include one or more MOs. If the scheduling occasion includes one MO, the contents of multiple pieces of SI messages can be sent on the MO. If the scheduling occasion includes multiple MOs, the contents of multiple pieces of SI messages can be sent on each MO, or the contents of different pieces of SI messages can be sent on different MOs of the multiple MOs, or the contents of multiple pieces of SI messages can be sent on some MOs of the multiple MOs, and the contents of one piece of SI message of the multiple pieces of SI messages can be sent on some MOs. In this way, the resources occupied by sending system information can be reduced, the problem of insufficient resources in the case of independent scheduling of multiple pieces of SI messages can be solved, the system information can be sent in a timely manner, and the performance of the terminal using the corresponding function of the system information can be improved or guaranteed. Moreover, the access network device can flexibly determine whether the contents of multiple pieces of SI messages using the same scheduling occasion are carried in the same SI message or different SI messages, which is beneficial to improving the efficiency of system information scheduling and better adapting to the resource situation in the cell.
[0223] Each embodiment of the present application is described by taking the first scheduling information list and the second scheduling information list as examples, but in fact, the technical solution is not limited to the case of only two scheduling information lists, and the technical logic is the same in the case of more than two scheduling information lists.
