Implementation of the invention

[0098] The technical solutions for the embodiments of the present disclosure will be clearly and fully disclosed below with reference to the accompanying drawings of the embodiments of the present disclosure. Upon reviewing the disclosed embodiments, it will become apparent that they are by no means all embodiments of the present disclosure. Any other embodiments that those skilled in the art will be able to create based on them without the application of inventive efforts, are included in the scope of this disclosure.

[0099] FIG. 1 is a flow diagram of a method for broadcasting SSB configuration information according to one embodiment of the present disclosure. The method of broadcasting the SSB configuration information of this embodiment can find application in a device capable of functioning as a base station in case of direct connection communication, such as a vehicle capable of emulating a base station for beam transmission. This vehicle can communicate with other vehicles using 5G NR technology.

[00100] The method of broadcasting SSB configuration information in FIG. 1 may include the following steps.

[00101] In step S11, determining the maximum number of SSB blocks that can be transmitted over the transmission bandwidth of the SSB block;

[00102] In step S12, the number of configuration information bits to be generated is determined by the ratio between the maximum number and the first predetermined number, and configuration information is generated with the specified number of bits. blocks SSB, with the first predetermined number positively correlated with the number of bits that can be transmitted through the physical direct broadcast channel.

[00103] In step S13, information is broadcast via a physical forward broadcast channel.

[00104] This embodiment is applicable in the case of communication using a vehicle to everything communication technology (Eng. Vehicle to Everything), in which the vehicle can communicate with other vehicles, on-board equipment and roadside equipment . For example, vehicle A may receive the signal transmitted by the base station, and vehicle B may not receive the signal transmitted by the base station for any reason (eg, being out of range of the base station). In this case, vehicle B can receive a signal transmitted by vehicle A, which is in relative proximity to vehicle B. Thus, vehicle A can first establish communication with the base station, receive information transmitted by the base station, and then emulate the base station for transmission of the transmitted signal via a beam so that vehicle B can receive the signal transmitted by vehicle A and obtain information transmitted by the base station based on the signal transmitted by vehicle A. Communication between vehicle A and vehicle B is not through the base station, but based on a direct connection. With this connection, vehicle A functions as a base station and vehicle B functions as a user device. The method of this embodiment may find application in vehicle A.

[00105] Since there is no information transfer in case of direct connection communication, unlike communication between a base station and a user device, embodiments of the present disclosure allow configuration information to be broadcast over a Physical Direct Broadcast Channel (PSBCH).

[00106] The larger the number of bits of configuration information, the more accurately the content can be expressed. For example, the maximum number of SSB blocks that can be transmitted is L (L may be 4, 8, 64, etc.), i. e. a maximum of L SSB blocks can be transmitted. In this case, there may be a case in which it is not necessary to transmit some SSB blocks. If the number of bits of the configuration information is L, it can be accurately indicated by the configuration information whether each of the L SSBs is an SSB to be transmitted.

[00107] Considering that the number of bits that can be transmitted via the physical forward broadcast channel is relatively limited, while the number of bits that can be transmitted does not necessarily reach the number L of SSBs that can be transmitted, it is necessary to adjust the number of information bits accordingly about configuration.

[00108] According to this embodiment, the maximum number L of SSB blocks that can be transmitted can be determined from the transmission bandwidth of the SSB block. The higher the center frequency of a frequency band, the easier it is to block signal transmission in that frequency band. Therefore, more SSBs must be transmitted to overcome the blocking effect. Therefore, the higher the center frequency of the band, the larger the value of L, and the lower the center frequency of the band, the smaller the value of L. Next, the number of configuration information bits to be generated is determined from the ratio between the maximum number and the first predetermined number K. Here, the first predetermined number positively correlates with the number of bits that can be transmitted over the physical forward broadcast channel. Those. the larger the number of bits that can be transmitted via the physical forward broadcast channel, the larger the first predetermined number, and the smaller the number of bits that can be transmitted via the physical forward broadcast channel, the smaller the first predetermined number.

[00109] For example, as the first predetermined number, you can select the maximum value of the number of bits that can be transmitted via the physical direct broadcast channel, or a value less than the maximum value of the number of bits that can be transmitted via the physical forward broadcast channel. In this case, the first predetermined number may be an upper limit value of the number of bits by which configuration information can be transmitted in the physical forward broadcast channel, and other bits in the physical forward broadcast channel are used to transmit content other than configuration information.

[00110] For example, the maximum value of the number of bits that can be transmitted by the physical forward broadcast channel is used as the first predetermined number. If the maximum number L of SSBs that can be transmitted does not exceed the first predetermined number K, this indicates that L bits of configuration information can be transmitted via the physical forward broadcast channel. Next, configuration information with a number of bits L can be generated to accurately indicate whether each of the L SSBs is an SSB to be transmitted. If the maximum number L of SSBs that can be transmitted is greater than the first predetermined number K, this indicates that it is not enough to transmit L bits of configuration information via the physical forward broadcast channel, and that the number of bits of configuration information generated must be less than L to ensure stable transmission of configuration information over the physical forward broadcast channel.

[00111] According to one embodiment of the present disclosure, in the case of direct connection communication, it is possible to broadcast configuration information via a physical direct broadcast channel, it is possible to determine the number of configuration information bits to be generated by the ratio between the maximum number and the first predetermined number, and generate configuration information with the specified number of bits to ensure stable transmission of the configuration information via the physical forward broadcast channel.

[00112] FIG. 2 is a schematic diagram of a sequence of determining the number of bits of configuration information from a ratio between the maximum number and the first predetermined number, and generating configuration information with the specified number of bits according to one embodiment of the present disclosure. As illustrated in FIG. 2, in this case, the number of bits of the configuration information is determined by the ratio between the maximum number and the first predetermined number, and the configuration information with the specified number of bits is generated in steps S121 and S122.

[00113] In step S121, it is determined whether the maximum number exceeds the first predetermined number.

[00114] In step S122, if the maximum number does not exceed the first predetermined number, configuration information with the maximum number of bits is generated. Wherein, each bit in the configuration information indicates whether the SSB is an SSB to be transmitted.

[00115] In one embodiment, for example, where the maximum value of the number of bits that can be transmitted by the physical forward broadcast channel is selected as the first predetermined number K, if the maximum number L does not exceed the first predetermined number K, this indicates that the maximum number L bits of configuration information can be transmitted via the physical forward broadcast channel. Next, configuration information with a number of bits L can be generated to accurately indicate whether each of the L SSBs is an SSB to be transmitted.

[00116] FIG. 3 is another circuit diagram of the sequence of determining the number of bits of configuration information from the ratio between the maximum number and the first predetermined number, and generating configuration information with the specified number of bits according to one embodiment of the present disclosure. As illustrated in FIG. 3, the maximum number of SSBs includes n SSB groups, with each SSB group including m SSBs. In this case, m and n are positive integers, and the number of configuration information bits is determined by the ratio between the maximum number and the first predetermined number, and configuration information with the specified number of bits is generated in steps S123 and S124:

[00117] In step S123, it is determined whether the maximum number exceeds the first predetermined number.

[00118] In step S124, if the maximum number exceeds the first predetermined number, n+m bit configuration information is generated. SSB blocks, and m bits of n+m bits are used to indicate whether each SSB block in the SSB block group to be transmitted is an SSB block to be transmitted.

[00119] In one embodiment, for example, where the maximum value of the number of bits that can be transmitted by the physical forward broadcast channel is selected as the first predetermined number, if the maximum number L is greater than the first predetermined number K, this indicates that that it is not sufficient to transmit L bits of configuration information via the physical forward broadcast channel. That is, the number of bits of the generated configuration information must be less than L in order to ensure stable transmission of the configuration information via the physical forward broadcast channel, with L=m×n.

[00120] It is also necessary to be able to accurately reflect which signal blocks out of the L signal blocks are signal blocks to be transmitted by the configuration information transmitted via the physical forward broadcast channel. Thus, this embodiment is mainly applicable in the case where the maximum number of SSBs includes n SSB groups, and each SSB group includes m SSBs. If the transmission options of SSBs at the same positions in each SSB group are the same, then whether each of the L SSBs is an SSB to be transmitted can be indicated by n+m bits of configuration information.

[00121] Taking L=64, m=8, and n=8 as an example, if some of the eight SSB block groups cannot be transmitted, 8 bits can indicate whether each of the eight SSB block groups is an SSB block group to be transmitted . For example, the second and seventh SSB block groups are not transmitted, n bits are 10111101, and m bits are used to indicate whether each SSB in the SSB block group to be transmitted is an SSB block to be transmitted. For example, if the third and fourth SSBs in each SSB group are not to be transmitted, then the SSBs to be transmitted in each SSB group may be indicated by m bits, with m bits being 11001111. Based on this, the transmission of 64 SSBs can be indicate by 16 bits, thereby reducing the number of bits of configuration information transmitted via the physical forward broadcast channel.

[00122] FIG. 4 is another circuit diagram of the sequence of determining the number of bits of configuration information from the ratio between the maximum number and the first predetermined number, and generating configuration information with the specified number of bits according to one embodiment of the present disclosure. As illustrated in FIG. 4, the maximum number of SSBs includes n SSB groups, with each SSB group including m SSBs. In this case, m and n are positive integers, and the number of configuration information bits is determined by the ratio between the maximum number and the first predetermined number, and configuration information with the specified number of bits is generated in steps S125 and S126.

[00123] In step S125, it is determined whether the maximum number exceeds the first predetermined number.

[00124] In step S126, if the maximum number exceeds the first predetermined number, the transmission beam where the configuration information is placed is determined, and the configuration information with (n-1)+(m-1) bits is generated. Here, n- 1 bit of (n-1)+(m-1) bits are used to indicate whether each SSB block group of n-1 SSB block groups other than the SSB block group containing the corresponding transmission beam block of the SSB block group to be transmitted is the SSB block group , wherein m-1 bits of (n-1)+(m-1) bits are used to indicate whether each of the m-1 SSBs of the SSBs to be transmitted, except for the SSB corresponding to the transmission bundle, is to be transmitted block SSB.

[00125] Although the embodiment of FIG. 3 allows to reduce the number of bits of configuration information transmitted by the physical forward broadcast channel, it should also be considered that the vehicle acting as a base station can determine the beam for transmitting configuration information, i.e. a transmission beam where the configuration information is located, and a vehicle functioning as a user equipment may determine the receiving beam of the configuration information, i. e. receive bundle containing configuration information. Therefore, when transmitting configuration information, one bit out of m bits can be omitted. This bit represents the transmission option of the target SSB corresponding to the bundle in which the configuration information is being transmitted. Since the target SSB is to be transmitted on this beam, this bit must be set to 1. Therefore, only the other m-1 bits need to be transmitted to indicate whether an SSB that is not a target SSB is to be transmitted.

[00126] In addition, since the target SSB block is transmitted, the target SSB block group containing the target SSB block is also transmitted. Therefore, the corresponding bit of the target SSB block group of n bits is also necessarily set to 1. Therefore, one bit of n bits can be omitted and only the other n-1 bits can be transmitted to indicate whether SSB groups of blocks that are not the target block group are to be transmitted. SSB.

[00127] In this embodiment, based on the embodiment in FIG. 3, it is possible to further reduce the number of bits of configuration information transmitted by the physical forward broadcast channel, and thereby reduce the load on the physical forward broadcast channel.

[00128] FIG. 5 is a sequence diagram of another method for broadcasting SSB configuration information according to one embodiment of the present disclosure. As illustrated in FIG. 5, the method further comprises the following steps.

[00129] In step S14, before the configuration information is broadcast by the physical forward broadcast channel, it is determined whether the number of configuration information bits exceeds a second predetermined number.

[00130] If the number of configuration information bits exceeds the second predetermined number, the configuration information is broadcast via the physical forward broadcast channel in step S131.

[00131] In step S131, the information of the second predetermined number of bits in the configuration information is broadcast through the physical forward broadcast channel, and the information of other bits in the configuration information is transmitted through other channels.

[00132] In one embodiment, the second predetermined number may be a value less than the maximum value of the number of bits that can be transmitted over a physical forward broadcast channel, wherein the second predetermined number may be an upper limit of the value of the number of bits by which to transmit configuration information on a physical forward broadcast channel. In this case, other bits in the physical forward broadcast channel must carry content other than configuration information. If the number of bits of the configuration information is greater than the second predetermined number, then it is not enough to transmit the configuration information only through the physical forward broadcast channel. Therefore, it is possible to broadcast the information of the second predetermined number of bits in the configuration information through a physical forward broadcast channel, and transmit information of other bits in the configuration information through other channels to enable stable transmission of the configuration information.

[00133] SSB blocks in a group of SSB blocks do not necessarily correspond to bundles one by one.

[00134] Multiple SSBs in a group of SSBs do not necessarily correspond to the same bundle.

[00135] In one embodiment, in addition to the situation in which SSBs correspond to beams one by one, it is also possible that several SSBs correspond to the same beam. In this situation, since the bundle can transmit multiple SSBs (not simultaneously, but at different times, and only one SSB can be transmitted at a time), the number of configuration information bits depends on the bundle, i.e. the number of bits of configuration information to be generated is determined by a ratio between the number corresponding to the maximum number of beams and the first predetermined number.

[00136] For example, if the maximum number of SSB blocks that can be transmitted is L=8 and the number of beams that can be transmitted is B _n =4, i.e. each beam can transmit two SSBs, the number of configuration information bits is determined based on B _n . The determination procedure is the same as in the previous embodiment. For example, if B _n is not greater than K, the configuration information is generated with the number of bits equal to B _n .

[00137] FIG. 6 is a flow diagram of a method for receiving SSB configuration information according to one embodiment of the present disclosure. The method of receiving SSB configuration information of this embodiment can find application in a device able to function as a user device in case of direct connection communication. For example, a vehicle communicating with a vehicle functioning as a base station in the embodiment of FIG. 1 can receive information broadcast by a vehicle operating as a base station in the embodiment of FIG. 1 using 5G NR technology.

[00138] As illustrated in FIG. 6, the method for receiving SSB configuration information may include steps S21 to S26.

[00139] In step S21, the maximum number of SSB blocks that can be received is determined by the reception bandwidth of the SSB block.

[00140] In step S22, a first predetermined number is determined based on the physical forward broadcast channel on which the SSB block is received in the specified frequency band. Here, the first predetermined number positively correlates with the number of bits that can be transmitted via the physical forward broadcast channel.

[00141] In step S23, the number of configuration information bits to be received is determined by the ratio between the maximum number and the first predetermined number. Here, the SSB to be received from the maximum number of SSBs is indicated by the configuration information.

[00142] In step S24, the configuration information is received via the physical forward broadcast channel.

[00143] In step S25, a parameter based on which the configuration information is parsed is determined by the number of bits.

[00144] In step S26, the configuration information is parsed based on the given parameter.

[00145] In one embodiment, the method of this embodiment may find application in a vehicle functioning as a user device, such as vehicle B in the embodiment of FIG. one.

[00146] Since the vehicle receiving the configuration information can determine the frequency band in which the configuration information is received, the maximum number of received SSBs can be determined. It is also possible to define a physical forward broadcast channel for receiving an SSB block, and to determine the maximum number L of SSB blocks that can be received via a physical forward broadcast channel. Next, the first predetermined number K is determined based on the physical direct broadcast channel in which the SSB block is received in the specified frequency band, and the number of configuration information bits to be received is determined by the ratio between the maximum number L and the first predetermined number K.

[00147] Based on the number of bits of the received configuration information, the vehicle determines a parameter in the configuration information parsing algorithm, then parses the configuration information, and determines the transmission mode of the SSB from the configuration information to receive the SSB.

[00148] FIG. 7 is a circuit diagram of a sequence for determining the number of bits of receiving configuration information from the relationship between the maximum number and the first predetermined number according to one embodiment of the present disclosure. As illustrated in FIG. 7, determination, by the ratio between the maximum number and the first predetermined number, of the number of configuration information reception bits is carried out in steps S231 and S232.

[00149] In step S231, it is determined whether the maximum number exceeds the first predetermined number.

[00150] In step S232, if the maximum number does not exceed the first predetermined number, a decision is made to receive configuration information with the maximum number of bits. Here, each bit in the configuration information indicates whether the SSB block is the SSB block to be received.

[00151] In one embodiment, corresponding to the embodiment of FIG. 2, if the maximum number L does not exceed the first predetermined number K, this indicates that the maximum number L of configuration information bits can be received via the physical forward broadcast channel. Those. a vehicle functioning as a base station can transmit a maximum number L bits of configuration information via a physical forward broadcast channel. Next, a decision is made to receive the configuration information with the number of bits equal to L.

[00152] FIG. 8 is another circuit diagram of a sequence for determining the number of bits of receiving configuration information from the relationship between the maximum number and the first predetermined number according to one embodiment of the present disclosure. As illustrated in FIG. 8, the maximum number of SSBs includes n SSB groups, with each SSB group including m SSBs. In this case, m and n are positive integers, and the number of configuration information reception bits is determined from the ratio between the maximum number and the first predetermined number in steps S233 and S234.

[00153] In step S233, it is determined whether the maximum number exceeds the first predetermined number.

[00154] In step S234, if the maximum number exceeds the first predetermined number, a decision is made to receive configuration information with n+m bits. In this case, n bits of n+m bits are used to indicate whether each of the n SSB block groups is a to-be-received SSB block group, and m bits of n+m bits are to indicate whether each SSB block is a to-be-received SSB block group. SSB blocks to be received by the SSB block.

[00155] In one embodiment, corresponding to the embodiment in FIG. 3, if the maximum number L exceeds the first predetermined number K, this indicates that it is not sufficient to receive L bits of configuration information via the physical forward broadcast channel. Those. it is not sufficient for a vehicle functioning as a base station to be able to transmit the maximum number L bits of configuration information via the physical forward broadcast channel. The vehicle operating as a base station generates and transmits configuration information with a number of bits less than L, while the number of received configuration information bits is also less than L, with L=m×n.

[00156] FIG. 9 is another circuit diagram of a sequence for determining the number of bits of receiving configuration information by the relationship between the maximum number and the first predetermined number according to one embodiment of the present disclosure. As illustrated in FIG. 9, the maximum number of SSBs includes n SSB groups, with each SSB group including m SSBs. In this case, m and n are positive integers, and determination of the number of configuration information bits from the ratio between the maximum number and the first predetermined number is carried out in steps S235 and S236.

[00157] In step S235, it is determined whether the maximum number exceeds the first predetermined number.

[00158] In step S236, if the maximum number exceeds the first predetermined number, a reception beam in which configuration information is received is determined, and a decision is made to receive configuration information with (n-1)+(m-1) bits. In this case, n-1 bits of (n-1)+(m-1) bits are used to indicate whether each SSB block group of the n-1 SSB block groups other than the SSB block group containing the SSB block corresponding to the bundle receive to be transmitted by a group of SSBs, where m-1 bits of (n-1)+(m-1) bits are used to indicate whether each of the m-1 SSBs of the SSBs to be transmitted, except for the corresponding to the receive beam of the SSB block to be transmitted by the SSB block.

[00159] In one embodiment, corresponding to the embodiment in FIG. 4, if the maximum number exceeds the first predetermined number, and the number of bits of the configuration information transmitted by the vehicle operating as the base station is (n-1)+(m-1), it can be determined that the number of bits of the received information about configuration is also (n-1)+(m-1).

[00160] In addition, since the reception beam in which the configuration information is received is known (for example, it can be determined when a communication connection is established with a vehicle functioning as a base station), when the configuration information is parsed, it can be determined that that the SSB corresponding to the receive beam is necessarily received. An SSB identification number is determined from which it is possible to determine which SSB of which group the given SSB is.

[00161] Taking as an example that L=64, m=8, n=8, and the SSB identification number is in the range of 0 to 63, it is determined that the SSB block corresponding to the reception beam has an identification number of 7, i.e. .e. the eighth SSB block in the first line is necessarily accepted. Based on this, it is possible to pad the received configuration information with (n-1)+(m-1) bits.

[00162] For example, in the case where the first n-1 bits indicate whether each of the (n-1) SSB block groups, except for the SSB block group corresponding to the receive beam block, the SSB block group to be transmitted, and the last (m -1) bits are used to indicate whether each of the (m-1) SSBs to be transmitted, except for the corresponding SSB receive beam, is an SSB to be transmitted, the first n-1 bits in the received configuration information are 0111101, and the last (m-1) bits are 1100111, the first bit of the first n-1 bits can be padded with 1 to get the first n bits of 10111101, and the eighth bit of the last (m-1) bits can be padded with 1 to get the last m bits of 11001111. Next, parsing is carried out based on the supplemented configuration information.

[00163] FIG. 10 is a sequence diagram of another direct connection communication method according to one embodiment of the present disclosure. As illustrated in FIG. 10, the method further comprises the following steps.

[00164] In step S27, before the configuration information is received by the physical forward broadcast channel, it is determined whether the number of configuration information bits exceeds a second predetermined number.

[00165] If the number of bits of the configuration information exceeds the second predetermined number, the configuration information is received via the physical forward broadcast channel in step S241.

[00166] In step S241, information of the second predetermined number of bits in the configuration information is received via a physical forward broadcast channel, and information of other bits in the configuration information is received via other channels.

[00167] In one embodiment, corresponding to the embodiment in FIG. 5, if the number of bits of the configuration information exceeds the second predetermined number, then the vehicle functioning as the base station can broadcast information of the second predetermined number of bits in the configuration information through a physical forward broadcast channel and transmit information of other bits in the information about configuration through other channels. Further, the vehicle functioning as the user equipment in this embodiment receives information of the second predetermined number of bits in the configuration information through a physical forward broadcast channel, and receives information of other bits in the configuration information through other channels.
