Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0150] In a non-terrestrial network (NTN) communication system, such as a 5G ground system, services and controls use the same beam. This mode is relatively simple to implement, but lacks flexibility. The implementation scheme of separating control and service beams can make full use of the power resources of the satellite payload, reduce the occupation of signaling, and allow the beam to allocate users on demand. Among them, the control beam is mainly used for uplink and downlink synchronization and access communication processes, and the service beam is mainly used for data transmission.
[0151] Taking the coverage of a single satellite as an example, the coverage of the satellite is divided into 36 beams, and a total of only 8 beams are supported according to the power capability. As shown in FIG. 1, a beam form in which control and service are combined is given, wherein each of the 8 beams supports control and service, resulting in only users in the coverage range of the control beam being able to be served. Figure 1 As shown in FIG. 2, a beam form in which control and service are separated is given, wherein one beam is dedicated to control, and the other 7 beams are used for service. Users obtain the basic information needed for access from the control beam, and then perform data transmission in the service beam. Figure 2
[0152] The embodiments of the present application provide a beam indication method, a beam determination method, an apparatus, a network device and a terminal, to solve the problem that the prior art does not have a technical means to distinguish the type of beam and the difference in the corresponding access process, thereby possibly causing errors in the access process.
[0153] Among them, the method and the apparatus (and the corresponding network device or terminal) are based on the same application concept, and since the principles of the method and the apparatus (and the corresponding network device or terminal) for solving problems are similar, the implementation of the apparatus (and the corresponding network device or terminal) and the method can be mutually referred to, and the repeated parts will not be described again.
[0154] As Figure 3 indicated, embodiments of the present application provide a beam indication method, comprising:
[0155] Step 31: The network device sends a downlink signal to the terminal through a downlink beam.
[0156] Wherein, the network device pre-configures different beam types corresponding to different frequency point information, and / or the downlink signal carries indication information for indicating the beam type corresponding to the downlink signal.
[0157] Optionally, the beam type includes a first beam type and / or a second beam type; wherein the first beam type is used for initial access and broadcast message transmission; the second beam type is used for data transmission, or the second beam type is used for data transmission and initial access.
[0158] Wherein, the first beam type can also be called a control beam, that is, the control beam is mainly used for initial access and broadcast message transmission, such as supporting the transmission / reception of broadcast signaling and synchronization access signals; the second beam type can also be called a service beam, that is, the service beam is mainly used for supporting user data transmission, and can also support user access and data transmission.
[0159] As an implementation manner, the network device can pre-configure different beam types corresponding to different frequency point information, so that the terminal can distinguish the beam types based on the frequency point information corresponding to the received downlink signal, such as distinguishing the first beam type (or called control beam) and the second beam type (or called service beam).
[0160] As another implementation manner, the network device can indicate the corresponding beam type through the indication information carried in the downlink signal, so that the terminal can distinguish the beam types based on the indication information, such as distinguishing the first beam type (or called control beam) and the second beam type (or called service beam).
[0161] In the scheme, the network device preconfigures different beam types to correspond to different frequency point information, so that when the network device sends a downlink signal to the terminal through a downlink beam, the terminal can determine the beam type of the downlink beam according to the frequency point information of the received downlink signal, and / or the network device carries indication information for indicating the beam type corresponding to the downlink signal in the downlink signal sent to the terminal through the downlink beam, so that the terminal can determine the beam type corresponding to the downlink signal according to the indication information. This scheme can facilitate the terminal to accurately identify the beam type of the received beam, so as to quickly establish communication with the network in the corresponding beam, and avoid the problem that the terminal may cause errors in the access process due to the failure to distinguish the beam type and the corresponding access process difference.
[0162] Specifically, in this scheme, the network device provides the terminal to distinguish different beam types in a preconfigured or signaling informed manner, which supports the terminal to select appropriate bandwidth resources and signal formats when initially accessing, so as to read the broadcast message and send the uplink access signal, complete the subsequent access process, and thus avoid errors in the access process of the terminal.
[0163] Optionally, in the case where the network device preconfigures different beam types to correspond to different frequency point information, the network device sends a downlink signal to the terminal through a downlink beam, including:
[0164] The network device sends a downlink signal corresponding to the frequency point information to the terminal through the downlink beam according to the frequency point information corresponding to the beam type of the downlink beam.
[0165] For example, in the case where the beam type includes a first beam type and a second beam type, the network device can preconfigure the first beam type to correspond to first frequency point information and the second beam type to correspond to second frequency point information; and the configuration information for indicating the mapping relationship between the beam type and the frequency point information can be pre-notified to the terminal by the network device side as a kind of agreement information.
[0166] In this way, the network device can send a downlink signal corresponding to the frequency point information to the terminal according to the preconfigured frequency point information corresponding to different beam types, so that the terminal side can perform cell search based on the preconfigured frequency point information corresponding to different beam types, and when receiving a downlink signal, can determine the beam type corresponding to the downlink signal based on the corresponding frequency point information when receiving the downlink signal, and then establish information interaction with the network based on the corresponding beam type, such as performing initial access, switching, etc. control process when the current beam is the first beam type (i.e. control beam); when the current beam is the second beam type (i.e. service beam), the terminal can perform data transmission or also can perform initial access.
[0167] Optionally, the network device sends a downlink signal to a terminal through a downlink beam, including:
[0168] The network device sends a broadcast message and / or a system message to the terminal through the downlink beam.
[0169] The broadcast message and / or the system message carries indication information for indicating the beam type corresponding to the downlink signal.
[0170] For example, the network device can carry the indication information for indicating the beam type corresponding to the downlink signal through MIB and / or through SIB; that is, the embodiment of the present application can distinguish the first beam type and the second beam type (that is, distinguish the control beam and the service beam) through MIB information and / or distinguish the first beam type and the second beam type (that is, distinguish the control beam and the service beam) through SIB.
[0171] Optionally, in the case that the broadcast message carries the indication information for indicating the beam type corresponding to the downlink signal, the indication information includes at least one of the following:
[0172] A first bit in the MIB;
[0173] A first field in the MIB.
[0174] The first bit in the MIB indicates the beam type corresponding to the downlink signal, for example, the network device increases a bit in the MIB information to explicitly indicate the beam type, that is, the MIB explicitly indicates the beam type corresponding to the downlink signal, and specifically, 1 bit can be used for indication, for example, 1 is the control beam and 0 is the service beam, or 0 is the control beam and 1 is the service beam, and the like. It should be noted that the first bit in the embodiment of the present application is not limited to a specific bit in the MIB, and it can be understood that a bit in the MIB can be used to explicitly indicate the beam type.
[0175] The first field in the MIB indicates the beam type corresponding to the downlink signal, for example, the network device uses different values of an existing field in the MIB information to mark the beam type, that is, the MIB implicitly indicates the beam type corresponding to the downlink signal, and the existing field can be at least one of a field for indicating a BWP index, a field for indicating a BWP type, a field for indicating a control channel index, and a field for indicating a control channel parameter.

Details of the same parts and beneficial effects of the method embodiment in the embodiment will not be repeated here.
[0260] The processor-readable storage medium can be any available medium or data storage device accessible by the processor, including but not limited to a magnetic memory (such as a floppy disk, a hard disk, a magnetic tape, a magneto-optical disk (MO), etc.), an optical memory (such as a CD, a DVD, a BD, a HVD, etc.), and a semiconductor memory (such as a ROM, an EPROM, an EEPROM, a non-volatile memory (NAND FLASH), a solid-state disk (SSD)), etc.
[0261] The above describes the beam indication method of the embodiment of the present application from the network device side. The beam determination method of the terminal side will be further described below in combination with the drawings.
[0262] As shown in FIG. 6, the embodiment of the present application provides a beam determination method, which comprises: Figure 6
[0263] Step 61: The terminal receives a downlink signal sent by a network device through a downlink beam.
[0264] The network device preconfigures different frequency point information corresponding to different beam types, and / or the downlink signal carries indication information for indicating a beam type corresponding to the downlink signal.
[0265] Optionally, the beam type comprises a first beam type and / or a second beam type; the first beam type is used for initial access and broadcast message transmission; and the second beam type is used for data transmission, or the second beam type is used for data transmission and initial access.
[0266] The first beam type can also be referred to as a control beam, that is, the control beam is mainly used for initial access and broadcast message transmission, such as supporting the sending / receiving of broadcast signaling and synchronization access signals; and the second beam type can also be referred to as a service beam, that is, the service beam is mainly used for supporting data transmission of a user, and can also support the access and data transmission of the user.
[0267] Step 62: The terminal determines a beam type of the downlink beam according to the downlink signal.
[0268] In the scheme, the network device pre-configures different beam types to correspond to different frequency point information, so that when the network device sends a downlink signal to the terminal through a downlink beam, the terminal can determine the beam type of the downlink beam according to the frequency point information of the received downlink signal, and / or the network device carries indication information for indicating the beam type corresponding to the downlink signal in the downlink signal sent to the terminal through the downlink beam, so that the terminal can determine the beam type corresponding to the downlink signal according to the indication information. This scheme can facilitate the terminal to accurately identify the beam type of the received beam, so as to quickly establish communication with the network in the corresponding beam, and avoid the problem that the terminal may cause errors in the access process due to the failure to distinguish the beam type and the corresponding access process difference.
[0269] Specifically, in this scheme, the network device provides the terminal to distinguish different beam types in a pre-configuration or signaling notification manner, which realizes that the terminal can select appropriate bandwidth resources and signal formats when initially accessing, so as to read the broadcast message and send the uplink access signal, complete the subsequent access process, and thus avoid errors in the access process of the terminal.
[0270] Optionally, after the terminal determines the beam type of the downlink beam according to the downlink signal, the method can further include:
[0271] The terminal uses an access mode corresponding to the beam type when initially accessing according to the beam type of the downlink beam, wherein different beam types correspond to different access modes.
[0272] Optionally, when the beam type is a first beam type (i.e., a control beam), the access mode can be that the terminal first sends a random access signal, then receives the random access signal, and the terminal performs subsequent random access operations according to the indication information of the random access signal. For example, if the terminal determines that the current beam is a control beam according to the downlink signal, the terminal can perform related processing of the control beam, such as initial access, switching, and other control processes.
[0273] When the beam type is a second beam type (i.e., a service beam), the access manner can be that the terminal first sends a random access preamble signal to the network; then receives a random access response (RAR) signal, sends a physical uplink shared channel (PUSCH) signal based on the RAR signal, carries uplink radio resource control (RRC) connection request information, and the terminal receives a network contention resolution signal. For example, if the terminal determines that the current beam is a service beam according to the downlink signal, the terminal can perform related processing of the service beam, such as data transmission or initial access.
[0274] Optionally, in a case where the network device preconfigures different beam types to correspond to different frequency point information, the terminal determines the beam type of the downlink beam according to the downlink signal, including:
[0275] If the terminal receives the downlink signal according to the first frequency point information, it is determined that the beam type of the downlink beam is a first beam type.
[0276] If the terminal receives the downlink signal according to the second frequency point information, it is determined that the beam type of the downlink beam is a second beam type.
[0277] For example, in a case where the beam type includes a first beam type and a second beam type, the network device can preconfigure the first beam type to correspond to first frequency point information and the second beam type to correspond to second frequency point information; the configuration information for indicating the mapping relationship between the beam type and the frequency point information can be pre-notified to the terminal by the network device side as a kind of agreement information, and the terminal side can pre-store the correspondence relationship between the frequency point information and the beam type preconfigured by the network device as a kind of agreement information.
[0278] In this way, the network device can send a downlink signal corresponding to the frequency point information to the terminal according to the preconfigured frequency point information corresponding to different beam types, so that the terminal side can perform cell search based on the preconfigured frequency point information corresponding to different beam types, and when receiving the downlink signal, can determine the beam type corresponding to the downlink signal based on the frequency point information of the received downlink signal, and then establish information interaction with the network based on the corresponding beam type. For example, when the current beam is a first beam type (i.e., a control beam), the terminal can perform access, switching, and other control processes; when the current beam is a second beam type (i.e., a service beam), the terminal can perform data transmission or initial access.
[0279] Optionally, the terminal receives a downlink signal sent by the network device through a downlink beam, including:
[0280] The terminal receives a broadcast message and / or a system message sent by the network device through a downlink beam.
[0281] The broadcast message and / or the system message carries indication information for indicating the beam type corresponding to the downlink signal.
[0282] For example, the network device can carry the indication information for indicating the beam type corresponding to the downlink signal through MIB and / or through SIB; that is, the embodiment of the application can distinguish the first beam type and the second beam type (that is, distinguish the control beam and the service beam) through MIB information and / or distinguish the first beam type and the second beam type (that is, distinguish the control beam and the service beam) through SIB.
[0283] Specifically, in the case that the network device is not preconfigured with different beam types corresponding to different frequency point information, that is, the terminal does not know the frequency point information of the first beam type and the second beam type (that is, the control beam and the service beam), the terminal can use a blind search method to search for a star, and after successful star search, MIB information can be acquired; in the case that the network device carries the indication information for indicating the beam type corresponding to the downlink signal through MIB, the terminal can determine from the MIB information whether the current beam is the first beam type or the second beam type (that is, determine whether the current beam is the control beam or the service beam).
[0284] And / or, in the case that the network device is not preconfigured with different beam types corresponding to different frequency point information, that is, the terminal does not know the frequency point information of the first beam type and the second beam type (that is, the control beam and the service beam), the terminal can use a blind search method to search for a star, and after successful star search, MIB, SIB and the like can be acquired; in the case that the network device carries the indication information for indicating the beam type corresponding to the downlink signal through SIB, the terminal can determine from the SIB information whether the current beam is the first beam type or the second beam type (that is, determine whether the current beam is the control beam or the service beam).
[0285] Optionally, in the case that the broadcast message carries the indication information for indicating the beam type corresponding to the downlink signal, the indication information includes at least one of the following:
[0286] A first bit in the MIB;
[0287] A first field in the MIB.
[0288] The first bit in the MIB indicates the beam type corresponding to the downlink signal. For example, the network device adds a bit in the MIB information to explicitly indicate the beam type, that is, the MIB explicitly indicates the beam type corresponding to the downlink signal. Specifically, 1 indicates a control beam, and 0 indicates a service beam. Alternatively, 0 indicates a control beam, and 1 indicates a service beam. It should be noted that the first bit in the MIB is not limited to a specific bit. It can be understood that any bit in the MIB can be used to explicitly indicate the beam type.
[0289] The first field in the MIB indicates the beam type corresponding to the downlink signal. For example, the network device uses different values of an existing field in the MIB information to mark the beam type, that is, the MIB implicitly indicates the beam type corresponding to the downlink signal. The existing field can be at least one of a field for indicating a BWP index, a field for indicating a BWP type, a field for indicating a control channel index, and a field for indicating a control channel parameter.
[0290] Optionally, when the first field in the MIB is used to indicate the beam type corresponding to the downlink signal, the first field can include at least one of the following:
[0291] The first field for indicating a BWP index. The BWP index is associated with a BWP type, and different beam types correspond to different BWP types. For example, the BWP index and the BWP type have a mapping relationship. By indicating the BWP index, the terminal can determine the corresponding BWP type based on the BWP index. For example, the BWP type corresponding to the first beam type (i.e., a control beam) can be an initial access BWP and / or a specific (or preconfigured) BWP type, which is different from the BWP type corresponding to the second beam type (i.e., a service beam).
[0292] The first field for indicating a BWP type. Different beam types correspond to different BWP types. For example, the BWP type corresponding to the first beam type (i.e., a control beam) can be an initial access BWP and / or a specific (or preconfigured) BWP type, which is different from the BWP type corresponding to the second beam type (i.e., a service beam).
[0293] a first field for indicating a control channel index; wherein the control channel index is associated with a control channel parameter, and different beam types correspond to different control channel parameters. For example, the control channel index and the control channel parameter have a mapping relationship, and by indicating the control channel index, the terminal can determine the corresponding control channel parameter based on the control channel index; for example, the control channel parameter of the first beam type (i.e., the control beam) includes 20 PRBs, 3 or 6 symbols, the control channel parameter of the second beam type (i.e., the service beam) includes a PRB number that is not 20, and / or a symbol number that is not 3 or 6, etc., and the embodiments of the present application are not limited thereto.
[0294] a first field for indicating a control channel parameter; wherein different beam types correspond to different control channel parameters. For example, the control channel parameter of the first beam type (i.e., the control beam) corresponding to different beam types is different, which can be, for example, the control channel parameter of the first beam type (i.e., the control beam) includes 20 PRBs, 3 or 6 symbols, the control channel parameter of the second beam type (i.e., the service beam) includes a PRB number that is not 20, and / or a symbol number that is not 3 or 6, etc., and the embodiments of the present application are not limited thereto.
[0295] Optionally, in the case that the indication information for indicating the beam type corresponding to the downlink signal is carried in the system message, the indication information includes at least one of the following:
[0296] a second bit in the first SIB;
[0297] a second field in the second SIB.
[0298] wherein the first SIB and the second SIB can be the same or different, such as the first SIB can be SIB1, and the second SIB can be SIBx (such as other SIBs in addition to SIB1, or a newly added SIB), etc., and the embodiments of the present application are not limited thereto.
[0299] wherein the second bit in the first SIB indicates the beam type corresponding to the downlink signal, such as the network device explicitly indicates the beam type by adding a bit in the first SIB information, that is, the first SIB explicitly indicates the beam type corresponding to the downlink signal, which can be, for example, 1-bit indication, such as 1 for control beam and 0 for service beam, or 0 for control beam and 1 for service beam, etc. It should be noted that the second bit in the embodiments of the present application is not limited to a specific bit in the first SIB, and it can be understood that any bit in the first SIB can be used to explicitly indicate the beam type.
[0300] The second field in the second SIB indicates the beam type corresponding to the downlink signal. For example, the network device uses different values of an existing field in the second SIB information to mark the beam type, that is, the second SIB implicitly indicates the beam type corresponding to the downlink signal. The existing field can be at least one of a field for indicating a beam width, a field for indicating a number of service wave positions, a field for indicating a bandwidth range, a field for indicating a cell identifier, a second field for indicating a BWP index, and a field for indicating a BWP type.

[0304] A second field for indicating a bandwidth range, wherein different beam types correspond to different bandwidth ranges. For example, the first beam type (i.e., the control beam) has a narrower bandwidth (i.e., a smaller bandwidth range), and the second beam type (i.e., the service beam) has a larger bandwidth (i.e., a larger bandwidth range).
[0305] A second field for indicating a cell identifier, wherein different beam types correspond to different cell identifiers. For example, the first beam type and the second beam type (i.e., the control beam and the service beam) correspond to different cell ID numbers.

For example, the BWP index and the BWP type have a mapping relationship, and by indicating the BWP index, the terminal can determine the corresponding BWP type based on the BWP index. For example, the first beam type (i.e., the control beam) corresponds to an initial access BWP and / or a specific (or preconfigured) BWP type, which is different from the BWP type corresponding to the second beam type (i.e., the service beam).
[0307] a second field for indicating a BWP type; wherein different beam types correspond to different BWP types.

[0383] The processor-readable storage medium can be any available medium or data storage device that a processor can access, including but not limited to a magnetic storage (e.g., floppy disks, hard disks, tape, MO, etc.), an optical storage (e.g., CD, DVD, BD, HVD, etc.), and a semiconductor storage (e.g., ROM, EPROM, EEPROM, NAND FLASH, SSD, etc.), etc.
[0384] The beam indication method of the present application is described below in combination with specific embodiments, wherein the control beam can refer to the first beam type described above, and the service beam can refer to the second beam type described above.
[0385] Embodiment one: independent working frequency band differentiation method, i.e., different beam types correspond to different frequency point information.
[0386] Specifically, the network device divides the control beam and the service beam into independent working frequency bands, and previously agrees on the frequency band F1 of the control beam and the frequency band F2 of the service beam, which are stored at the terminal (UE) side and the network side. When accessing the network, the UE judges whether it is a control beam or a service beam according to the frequency of the downlink signal.
[0387] For example: the control beam works in 19GHz-19.02GHz, a total of 20MHz; the service beam works in 19.02GHz-20.02GHz, a total of 1GHz. The frequency bands of the control beam and the service beam are independent and do not overlap, which is easy for the UE to distinguish. The UE can identify the control beam or the service beam through the working frequency band.
[0388] Embodiment two: using broadcast message MIB to indicate beam type
[0389] Specifically, the identification bit of the MIB information in the broadcast message is used to indicate the beam type, which distinguishes whether the current beam belongs to the control beam or the service beam.
[0390] Method (1): 1bit beam identification is added in MIB to indicate the beam type. Specifically, 1bit is added in the MIB information to indicate the beam type: "0" represents the control beam, and "1" represents the service beam.
[0391] Way (2): Based on the parameter indication of control channel, the PRB of control channel (such as PDCCH) of specific control beam is fixed 20, and the symbol number is 3 or 6. The PRB number and symbol number of control channel (PDCCH) of service beam are not fixed and variable. For example: if the PRB of PDCCH is 20, and the symbol number is 3 or 6, it indicates that the beam is a control beam. If the PRB of PDCCH is 20, and the symbol number ≠ 3, or the PRB ≠ 20, and the symbol number = 3, or the PRB ≠ 20, and the symbol number ≠ 3, it indicates that the beam is a service beam.
[0392] Way (3): Based on the high 4 bits of pdcch-ConfigSIB1 in MIB to indicate the beam type, that is, to indicate the beam type through the control channel index. For example: when the high four bits of Pdcch-ConfigSIB1 take values: “0000”-“1001”, it indicates a service beam; when the high four bits of Pdcch-ConfigSIB1 take values: “1100”-“1111”, it indicates a control beam.
[0393] As shown in Table 1, embodiments of way (2) and way (3) are given, the first column is the index (index) indicated by Pdcch-ConfigSIB1, and the second column and the second column indicate the PDCCH symbol number and RB number.
[0394] Table 1
[0395]
[0396]
[0397] Embodiment three: using system message SIB1 to indicate the beam type;
[0398] For example: add 1 bit in SIB1 to indicate the beam type: “0” indicates a control beam, and “1” indicates a service beam.
[0399] Embodiment four: implicitly indicating the beam type by using other system messages SIBx;
[0400] Way (1): Based on different beam width (pattern) to indicate the beam type, the pattern of the beam indicates the order of accessing different wave positions, which is indicated in SIB. Among them, the control beam adopts polling mode, and the pattern of the control beam access is fixed; the pattern of the service beam is related to the scheduling state of the current network, and is variable. For example: if the beam pattern indicated by the current SIB is fixed, it indicates a control beam; if the beam pattern indicated by the current SIB is variable and aperiodic, it indicates a service beam.
[0401] Way (2): Indicate the beam type based on different service beam position number, specifically distinguish the control beam and the service beam through the service beam number indicated by SIB. For example: the service beam position number of the control beam is different from the service beam position number of the service beam, the service beam position number of the control beam is less, and the service beam position number of the service beam is more. Then, "less service beam position number" indicates the control beam, and "more service beam position number" indicates the service beam.
[0402] Way (3): Indicate the beam type based on different beam bandwidth, specifically distinguish the control beam or the service beam by using the bandwidth of the current beam. For example: the bandwidth of the control beam is fixed, and the bandwidth of the service beam is greater than that of the control beam. For example, "small beam bandwidth" indicates the control beam, and "large beam bandwidth" indicates the service beam.
[0403] Way (4): Indicate the beam type based on different cell IDs, specifically distinguish the control beam or the service beam by using the cell ID. For example: a fixed cell ID is assigned to the control beam, such as "0" indicating the control beam cell, and "others" indicating the service beam cell.
[0404] Way (5): Indicate the beam type based on different BWP types, specifically define a special type of BWP, which is different from the existing initial BWP and dedicated BWP. Indicate the special type of BWP in SIB1, which indicates the control beam, such as defining as initial access BWP, so as to distinguish the control beam or the service beam by using the BWP type.
