[0099] For the convenience of those skilled in the art, the embodiments of the present disclosure enumerate a plurality of embodiments to clearly describe the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the plurality of embodiments provided by the embodiments of the present disclosure can be executed alone, or can be executed together with the method of other embodiments of the present disclosure, or can be executed alone or together with some methods in other related technologies; the embodiments of the present disclosure do not make any limitation in this regard.

[0100] In a mobile communication system (such as a 5G mobile communication system), a base station can use beamforming technology to provide a beam for signal coverage in a specific direction. The network-controlled repeater also uses beamforming technology to provide a beam for signal coverage in a specific direction.

[0101] How to indicate the beam of the access link to the network-controlled repeater, and how to indicate the time domain resource configuration information of the beam to the network-controlled repeater, are problems to be solved.

[0102] AsFigure 3 As shown, the present exemplary embodiment provides an information transmission method, applied to an access network device, comprising:

[0103] Step 301: sending, to a network-controlled relay, control information carrying N beam identification domains, wherein the beam identification domain is used to carry beam indication information for determining an access link beam identification, wherein N is less than or equal to M, M is the maximum number of beams supported by the access link, and at least one of N, the association relationship between the beam indication information and the beam identification, and the bit width of each beam identification domain is indicated by first configuration information.

[0104] The access network device can include a base station in a cellular mobile communication system, such as a 5G and subsequent cellular mobile communication system.

[0105] In one possible implementation, the access network device can send information for controlling the network-controlled relay to the network-controlled relay through a control link.

[0106] In one possible implementation, sending the control information carrying N beam identification domains to the network-controlled relay includes sending the control information carrying N beam identification domains to a mobile terminal in the network-controlled relay.

[0107] In one possible implementation, the access network device can send the control information carrying N beam identification domains to the network-controlled relay through a control link.

[0108] In one possible implementation, the control information can include downlink control information (DCI). In particular, the DCI is scrambled by an RNTI dedicated to the NCR.

[0109] In one possible implementation, one beam identification domain is used to carry beam indication information for one beam identification.

[0110] In one possible implementation, the control information is associated with, but not limited to, the beam identification of aperiodic beams.

[0111] The beam identification can be used to uniquely identify the beam of the access link. The access link can be a link between the UE and the network-controlled relay. The access link beam identification is used to identify the beam of the access link. Here, the beam of the access link can be generated by the network-controlled relay.

[0112] For the access link, the network-controlled relay can support at most M beams. The control information can carry N beam identification domains for indicating N beam identifications, i.e., the control information can be used to simultaneously indicate at most N beams.

[0113] In a possible implementation, the network-controlled repeater can obtain beam indication information carried by the N beam identification domains according to the received control information, and then determine the beam identifications corresponding to the N beams respectively. That is, the network-controlled repeater can determine the beams used by the network-controlled repeater for relaying.

[0114] In an embodiment, the first configuration information is determined by the access network device;

[0115] Alternatively,

[0116] The first configuration information is determined based on a predefined rule.

[0117] In a possible implementation, the predefined rule can be agreed by the network device and the network-controlled repeater.

[0118] In a possible implementation, the predefined rule can be specified by a communication protocol.

[0119] Here, the association between the beam indication information and the beam identification can include but is not limited to at least one of the following:

[0120] A mapping relationship between the beam indication information and the beam identification;

[0121] A rule for determining the beam identification through the beam indication information;

[0122] Different beam identifications corresponding to different beam indication information.

[0123] Based on the first configuration information, the NCR can determine the length of the control information according to N and the bit width of the beam identification domain. The beam indication information carried by each beam identification domain is determined according to the association between the beam indication information and the beam identification, and then the determination of the access link beam is realized.

[0124] The network-controlled repeater can determine the beam generated on the access link based on the control information.

[0125] In this way, the access network device sends the control information carrying the beam indication information of the N beams to the network-controlled repeater, and can determine the beam identification of the beam identification domain according to the first configuration information, thereby realizing the indication of the access link beam by the access network device, and then realizing the practical application of the network-controlled repeater beamforming technology in the mobile communication system, and improving the signal coverage of the mobile communication system.

[0126] As Figure 4 shown, the present exemplary embodiment provides an information transmission method applied to an access network device, comprising:

[0127] Step 401: sending indication information indicating N to the network-controlled repeater.

[0128] In one possible implementation, N may not be indicated by the first configuration information, but by indication information different from the first configuration information.

[0129] In one possible implementation, sending indication information indicating N to the network control repeater includes sending indication information indicating N to the network control repeater before sending control information carrying N beam identifier fields to the network control repeater.

[0130] In one possible implementation, the instruction information sent to the network control repeater indicating N includes configuration information sent via RRC signaling.

[0131] By sending indication information (N) to the network control repeater, the access network device can indicate the number of beams for the access link. The network control repeater can then determine the number of beam identifiers for the access link contained in the control information.

[0132] like Figure 5 As shown, this exemplary embodiment provides an information transmission method applied to an access network device, including:

[0133] Step 501: Send the first configuration information to the network control repeater.

[0134] In one possible implementation, sending the first configuration information to the network control repeater includes sending the first configuration information to the network control repeater before sending control information carrying N beam identifier fields to the network control repeater.

[0135] In one possible implementation, if the first configuration information is specified by a communication protocol, the network control repeater can determine the first configuration information based on the communication protocol.

[0136] Based on the first configuration information, the network control repeater can determine the length of the control information according to N and the bit width of the beam identifier field, etc.

[0137] In one possible implementation, the network control repeater can determine the length of the DCI based on N and the bit width of the beam identifier field, etc.

[0138] In one possible practical approach, the first configuration information is carried in RRC signaling.

[0139] In one embodiment, when the beam indication information is a predetermined value, the beam indication information does not indicate a valid beam identifier.

[0140] Here, the first configuration information can be configured with one or more predetermined values. When the beam indication information is a predetermined value, the beam indication information does not indicate any valid beam identifier. That is, when the bit code in the beam identifier field is a predetermined value, the beam identifier field is not used to indicate any valid beam identifier.

[0141] In one possible practical approach, the effective beam identifier could be an actual beam identifier that exists in the NCR.

[0142] For example, the bit width of each beam identifier field; and / or the beam identifier corresponding to the beam indication information (i.e., the bit code in the beam identifier field) in each beam identifier field is indicated by the base station through the first configuration information.

[0143] For example, a base station can configure NCR-ap-beam::=[-1, 0, 1, 2, 7, 8] via RRC; when the bit code is 0, the beam ID in the first configuration information is -1, which is not a valid beam identifier, indicating that no valid beam identifier is indicated. When the bit code is 2, it corresponds to beam identifier #1 (ID#1).

[0144] For example, the bit width of each beam identifier field; and / or the beam identifier corresponding to the beam indication information (i.e., the bit code in the beam identifier field) in each beam identifier field is predefined, that is, the first configuration information is predefined.

[0145] For example, using a standard predefined method, when the bit code is in a special state, such as all 1s, it indicates that no valid beam is indicated. Other valid values ​​indicate beam identification, such as bit code 1 corresponding to beam #1 and bit code 7 corresponding to beam #7.

[0146] For example, the maximum number of beams supported by the NCR on the access link is M. The DCI sent by the base station to the network control repeater contains N beam identification fields (or beam indication fields), that is, one DCI indicates at most N beams at a time.

[0147] If the first configuration information is determined based on predefined rules, then the bit width of each beam identifier field can be represented by expression (1):

[0148] bitwidth=ceiling[log2(M+1)] (1)

[0149] Where bitwidth represents the beam identifier field bit width, ceiling represents rounding up, and 1 represents the defined special state (i.e., the aforementioned predetermined value).

[0150] If the first configuration information is sent by the base station to the network control repeater, for example, via RRC.

[0151] The bit width of each beam identifier field can then be represented by expression (2):

[0152] bitwidth=ceiling[log2(X)] (2)

[0153] Where bitwidth represents the width of the beam identifier field, ceiling represents rounding up, and X represents the X beam IDs selected from the M beam IDs, that is, X is the number of beams that can be indicated, and the X IDs generally include special states, such as -1.

[0154] The network control repeater can determine the length of the beam information in the DCI by using N and the bit width of the beam identifier field, and thus determine the length of the DCI.

[0155] In one embodiment, the beam indication information carried by each of the N beam identification fields is a predetermined value, indicating that at least the forwarding Fwd function in the network control repeater is turned off.

[0156] To disable at least the Fwd function in a network control repeater, the base station can set the beam indication information of all N beam identifier fields in the control information to a predetermined value, meaning that none of the N beam identifier fields indicate any valid beam identifier. Upon receiving the control information, if the network control repeater determines that the beam indication information of all N beam identifier fields is at the predetermined value, it can confirm that at least the Fwd function of the network control repeater is disabled.

[0157] In one possible implementation, disabling at least one of the following functions of the network control repeater: the network control repeater stops relay service; the network control repeater does not forward signals.

[0158] Thus, on the one hand, the access network device can indicate the bit width and number of beam identifier fields to the network control repeater through the first configuration information. The network control repeater can then determine the length of the control information and receive it based on that length, such as performing blind detection, reducing the complexity of receiving control information. On the other hand, the access network device can indicate the association between beam indication information and beam identifiers to the network control repeater through the first configuration information, enabling the network control repeater to determine the access link beam identifier and thus achieve signal forwarding in a specific direction. Furthermore, the access network device can indicate to the network control repeater through the first configuration information whether the network control repeater's at least FWD (Front-Wave Detection) function is disabled if the beam identifier field does not indicate any valid beam identifier.

[0159] In one embodiment, the control information further includes:

[0160] The time-domain resource field is used to carry resource indication information that determines the time-domain resource corresponding to each of the beam identifiers.

[0161] Here, there can be one or more time-domain resource fields, and the resource indication information of each time-domain resource field can be used to indicate time-domain resources.

[0162] In one possible implementation, a time-domain resource field can indicate the time-domain resource corresponding to a beam identifier field.

[0163] In one possible implementation, one time-domain resource field can indicate the time-domain resources corresponding to multiple beam identifier fields.

[0164] In one possible implementation, the correspondence between the beam identifier domain and the time-domain resource domain is determined by predefined rules.

[0165] In this way, the access network equipment can indicate the time-domain resources corresponding to each beam identifier to the network control repeater by carrying the resource indication information in the time-domain resource domain. The network control repeater can then perform beam-based data transmission based on the time-domain resources, thereby realizing mobile communication relay.

[0166] In one embodiment, there are N time-domain resource domains, and each time-domain resource domain corresponds to one of the beam identifiers;

[0167] or,

[0168] There is one time-domain resource domain, and each beam identifier occupies one sub-time-domain resource of the time-domain resource indicated by the resource indication information, wherein the sub-time-domain resources do not overlap.

[0169] In one possible implementation, there are N time-domain resource domains, and each time-domain resource domain can correspond to a beam identifier domain.

[0170] In one possible implementation, the time-domain resource domain and the beam identifier domain can correspond one-to-one according to their respective order in the control information.

[0171] In one possible implementation, the resource indication information may indicate the time-domain resource in the form of, but not limited to, {X, Y, Z}, where X represents the offset between the starting slot of the time-domain resource and the slot for receiving control information, Y represents the starting symbol of the time-domain resource in the starting slot, and Z represents the number of symbols for the duration of the time-domain resource.

[0172] For example, if the resource indication information is {1, 1, 10}, and the network control repeater receives the DCI (control information) in slot #n, the beam can be transmitted on the 1st to 10th symbols in slot #n+1.

[0173] In one possible implementation, N beams can each occupy a portion of the time-domain resources indicated by the resource indication information, i.e., occupy sub-time-domain resources of the time-domain resources. And each sub-time-domain resource does not overlap.

[0174] In one embodiment, there is one time-domain resource domain, and the time-domain resources indicated by the resource indication information are evenly distributed among N beam identifiers.

[0175] If the control information contains only one time-domain resource field, and the resource indication information within that field indicates only one time-domain resource, then that time-domain resource can be evenly allocated to the beams corresponding to the N beam identifiers.

[0176] In one possible implementation, N beams can occupy time-domain resources sequentially according to the order of their respective beam identifier fields.

[0177] For example, if the control information has only one time-domain resource field, and the resource indication information in the time-domain resource field indicates a time-domain resource {1, 1, 3}, the control information has three beam identifier fields, indicating three beam identifiers: beam #1, beam #2, and beam #3. Assuming the network control repeater receives the DCI (control information) in slot #n, then beam #1 is transmitted on the first symbol of slot #n+1; beam #2 is transmitted on the second symbol of slot #n+1; and beam #3 is transmitted on the third symbol of slot #n+1.

[0178] In this way, the network control repeater can determine the beam identifier and time domain resources of the beam that need to communicate on the access link through control information, thereby realizing beam-based relay communication.

[0179] The order of the steps listed in the above embodiments is not intended to limit the execution order of the steps. Each step can be executed in the order listed, or it can be executed in a different order if there is no contradiction. Each step can be implemented as a separate embodiment if there is no contradiction, or multiple steps can be combined as an embodiment.

[0180] The above embodiments can be implemented individually, or two or more embodiments can be combined together without contradiction.

[0181] In the above embodiments, the information transmission methods executed on the network control repeater side and the access network side can be one-to-one corresponding. Therefore, the same explanations or features will not be repeated one by one, and the corresponding side embodiments can be referred to.

[0182] like Figure 6 As shown, this exemplary embodiment provides an information transmission method applied to a network control repeater, including:

[0183] Step 601: Receive control information sent by the access network device carrying N beam identifier fields, wherein the beam identifier field is used to carry beam indication information for determining the beam identifier of the access link, wherein N is less than or equal to M, and M is the maximum number of beams supported by the access link, wherein at least one of N, the association between the beam indication information and the beam identifier, and the bit width of each beam identifier field is indicated by the first configuration information.

[0184] Access network equipment may include base stations in cellular mobile communication systems (such as 5G and subsequent cellular mobile communication systems).

[0185] In one possible implementation, the control information may include downlink control information (DCI). Specifically, this DCI is scrambled using NCR-specific RNTI.

[0186] In one possible implementation, the access network device can send information for controlling the network control repeater to the network control repeater via a control link.

[0187] In one possible implementation, the network control repeater can receive control information carrying N beam identifier fields via a control link.

[0188] In one possible implementation, receiving control information carrying N beam identifier fields sent by the access network device includes: a mobile terminal in a network control repeater receiving control information carrying N beam identifier fields sent by the access network device.

[0189] In one possible implementation, a beam identifier field is used to carry beam indication information for a beam identifier.

[0190] In one possible implementation, the control information is associated with, but is not limited to, the beam identifier of an aperiodic beam.

[0191] A beam identifier is used to uniquely identify the beam of an access link. An access link can be a link between the UE and a network control repeater. The access link beam identifier is used to identify the beam of the access link. Here, the beam of the access link can be generated by the network control repeater.

[0192] For access links, network control repeaters can support up to M beams. Control information can carry N beam identifier fields to indicate N beam identifiers, meaning control information can be used to indicate N beams simultaneously.

[0193] In one possible implementation, the network control repeater can obtain the beam indication information carried by each of the N beam identifier fields based on the received control information, and then determine the beam identifiers corresponding to the N beams. That is, the network control repeater can determine the beams used for relaying.

[0194] In one embodiment, the first configuration information is determined by the access network device;

[0195] or,

[0196] The first configuration information is determined based on predefined rules.

[0197] In one possible implementation, the predefined rules can be agreed upon by the network devices and the network control repeater.

[0198] In one possible implementation, the predefined rules can be those specified by the communication protocol.

[0199] Here, the association between beam indication information and beam identifier may include, but is not limited to, at least one of the following:

[0200] The mapping relationship between beam indication information and beam identifier;

[0201] The rules for beam identification are determined by beam indication information;

[0202] The beam identifiers corresponding to different beam indication information.

[0203] Based on the first configuration information, NCR and other systems can determine the length of the control information according to N and the bit width of the beam identifier field. The beam indication information carried by each beam identifier field is determined according to the association between the beam indication information and the beam identifier, thereby enabling the determination of the access link beam.

[0204] Network control repeaters can determine the beam generated on the access link based on control information.

[0205] In this way, the network control repeater receives beam indication information of N beams carried by the control information, and can determine the beam identifier of the beam identifier field according to the first configuration information, and can determine the access link beam, thereby realizing the practical application of network control repeater beamforming technology in mobile communication systems and improving the signal coverage of mobile communication systems.

[0206] like Figure 7As shown, this exemplary embodiment provides an information transmission method applied to a network control repeater, including:

[0207] Step 701: Receive indication information of indication N sent by the access network device.

[0208] In one possible implementation, sending indication information indicating N to the network control repeater includes sending indication information indicating N to the network control repeater before sending control information carrying N beam identifier fields to the network control repeater.

[0209] In one possible implementation, the instruction information sent to the network control repeater indicating N includes configuration information sent via RRC signaling.

[0210] By receiving the indication information N, the network control repeater can determine the number of beam identifiers for the access link contained in the control information.

[0211] like Figure 8 As shown, this exemplary embodiment provides an information transmission method applied to a network control repeater, including:

[0212] Step 801: Receive the first configuration information sent by the access network device.

[0213] In one possible implementation, sending the first configuration information to the network control repeater includes sending the first configuration information to the network control repeater before sending control information carrying N beam identifier fields to the network control repeater.

[0214] In one possible implementation, if the first configuration information is specified by a communication protocol, the network control repeater can determine the first configuration information based on the communication protocol.

[0215] Based on the first configuration information, the network control repeater can determine the length of the control information according to N and the bit width of the beam identifier field, etc.

[0216] In one possible implementation, the network control repeater can determine the length of the DCI based on N and the bit width of the beam identifier field, etc.

[0217] In one possible practical approach, the first configuration information is carried in RRC signaling.

[0218] In one embodiment, when the beam indication information is a predetermined value, the beam indication information does not indicate a valid beam identifier.

[0219] Here, the first configuration information can be configured with one or more predetermined values. When the beam indication information is a predetermined value, the beam indication information does not indicate any valid beam identifier. That is, when the bit code in the beam identifier field is a predetermined value, the beam identifier field is not used to indicate the beam identifier.

[0220] In one possible practical approach, the effective beam identifier could be an actual beam identifier that exists in the NCR.

[0221] For example, the bit width of each beam identifier field; and / or the beam identifier corresponding to the beam indication information (i.e., the bit code in the beam identifier field) in each beam identifier field is indicated by the base station through the first configuration information.

[0222] For example, a base station can configure NCR-ap-beam::=[-1, 0, 1, 2, 7, 8] via RRC; when the bit code is 0, the beam ID in the first configuration information is -1, which is not a valid beam identifier, indicating that no valid beam identifier is indicated. When the bit code is 2, it corresponds to beam identifier #1 (ID#1).

[0223] For example, the bit width of each beam identifier field; and / or the beam identifier corresponding to the beam indication information (i.e., the bit code in the beam identifier field) in each beam identifier field is predefined, that is, the first configuration information is predefined.

[0224] For example, using a standard predefined method, when the bit code is in a special state, such as all 1s, it indicates that no valid beam is indicated. Other valid values ​​indicate beam identification, such as bit code 1 corresponding to beam #1 and bit code 7 corresponding to beam #7.

[0225] For example, the maximum number of beams supported by the NCR on the access link is M. The DCI sent by the base station to the network control repeater contains N beam identification fields (or beam indication fields), that is, one DCI indicates at most N beams at a time.

[0226] If the first configuration information is determined based on predefined rules, then the bit width of each beam identifier field can be represented by expression (1):

[0227] bitwidth=ceiling[log2(M+1)] (1)

[0228] Where bitwidth represents the beam identifier field bit width, ceiling represents rounding up, and 1 represents the defined special state (i.e., the aforementioned predetermined value).

[0229] If the first configuration information is sent by the network control repeater to the network control repeater, for example, carried via RRC.

[0230] The bit width of each beam identifier field can then be represented by expression (2):

[0231] bitwidth=ceiling[log2(X)] (2)

[0232] Where bitwidth represents the width of the beam identifier field, ceiling represents rounding up, and X represents the X beam IDs selected from the M beam IDs, that is, X is the number of beams that can be indicated, and the X IDs generally include special states, such as -1.

[0233] The network control repeater can determine the length of the beam information in the DCI by using N and the bit width of the beam identifier field, and thus determine the length of the DCI.

[0234] like Figure 9 As shown, this exemplary embodiment provides an information transmission method applied to a network control repeater, including:

[0235] Step 901: In response to the fact that the beam indication information carried by each of the N beam identification fields is a predetermined value, determine that at least the forwarding Fwd function in the network control repeater is turned off.

[0236] To disable the network control repeater, the base station can set the beam indication information of all N beam identifier fields in the control information to a predetermined value, meaning that none of the N beam identifier fields indicate any valid beam identifier. Upon receiving the control information, if the network control repeater determines that the beam indication information of all N beam identifier fields is at the predetermined value, it can determine that at least the Fwd function of the network control repeater is disabled.

[0237] In one possible implementation, disabling at least one of the following functions of the network control repeater: the network control repeater stops relay service; the network control repeater does not forward signals.

[0238] Thus, on the one hand, the access network device can indicate the bit width and number of beam identifier fields to the network control repeater through the first configuration information. The network control repeater can then determine the length of the control information and receive it based on that length, such as performing blind detection, reducing the complexity of receiving control information. On the other hand, the access network device can indicate the association between beam indication information and beam identifiers to the network control repeater through the first configuration information, enabling the network control repeater to determine the access link beam identifier and thus achieve signal forwarding in a specific direction. Furthermore, the access network device can indicate to the network control repeater, through the first configuration information, whether the FWD function in the network control repeater is disabled in cases where the beam identifier field does not indicate a beam identifier.

[0239] In one embodiment, the control information further includes:

[0240] The time-domain resource field is used to carry resource indication information that determines the time-domain resource corresponding to each of the beam identifiers.

[0241] Here, there can be one or more time-domain resource fields, and the resource indication information of each time-domain resource field can be used to indicate time-domain resources.

[0242] In one possible implementation, a time-domain resource field can indicate the time-domain resource corresponding to a beam identifier field.

[0243] In one possible implementation, one time-domain resource field can indicate the time-domain resources corresponding to multiple beam identifier fields.

[0244] Thus, the resource indication information carried in the time-domain resource domain enables the network control repeater to determine the time-domain resources corresponding to each beam identifier. The network control repeater can then perform beam-based data transmission based on these time-domain resources, thereby achieving mobile communication relay.

[0245] In one embodiment, there are N time-domain resource domains, and each time-domain resource domain corresponds to one of the beam identifiers;

[0246] or,

[0247] There is one time-domain resource domain, and each beam identifier occupies one sub-time-domain resource of the time-domain resource indicated by the resource indication information, wherein the sub-time-domain resources do not overlap.

[0248] In one possible implementation, there are N time-domain resource domains, and each time-domain resource domain can correspond to a beam identifier domain.

[0249] In one possible implementation, the time-domain resource domain and the beam identifier domain can correspond one-to-one according to their respective order in the control information.

[0250] In one possible implementation, the resource indication information may indicate the time-domain resource in the form of, but not limited to, {X, Y, Z}, where X represents the offset between the starting slot of the time-domain resource and the slot for receiving control information, Y represents the starting symbol of the time-domain resource in the starting slot, and Z represents the number of symbols for the duration of the time-domain resource.

[0251] For example, if the resource indication information is {1, 1, 10}, and the network control repeater receives the DCI (control information) in slot #n, the beam can be transmitted on the 1st to 10th symbols in slot #n+1.

[0252] In one possible implementation, N beams can each occupy a portion of the time-domain resources indicated by the resource indication information, i.e., occupy sub-time-domain resources of the time-domain resources. And each sub-time-domain resource does not overlap.

[0253] In one embodiment, there is one time-domain resource domain, and the time-domain resources indicated by the resource indication information are evenly distributed among N beam identifiers.

[0254] If the control information contains only one time-domain resource field, and the resource indication information within that field indicates only one time-domain resource, then that time-domain resource can be evenly allocated to the beams corresponding to the N beam identifiers.

[0255] In one possible implementation, N beams can occupy time-domain resources sequentially according to the order of their respective beam identifier fields.

[0256] For example, if the control information has only one time-domain resource field, and the resource indication information in the time-domain resource field indicates a time-domain resource {1, 1, 3}, the control information has three beam identifier fields, indicating three beam identifiers: beam #1, beam #2, and beam #3. Assuming the network control repeater receives the DCI (control information) in slot #n, then beam #1 is transmitted on the first symbol of slot #n+1; beam #2 is transmitted on the second symbol of slot #n+1; and beam #3 is transmitted on the third symbol of slot #n+1.

[0257] In this way, the network control repeater can determine the beam identifier and time domain resources of the beam that need to communicate on the access link through control information, thereby realizing beam-based relay communication.

[0258] The order of the steps listed in the above embodiments is not intended to limit the execution order of the steps. Each step can be executed in the order listed, or it can be executed in a different order if there is no contradiction. Each step can be implemented as a separate embodiment if there is no contradiction, or multiple steps can be combined as an embodiment.

[0259] The above embodiments can be implemented individually, or two or more embodiments can be combined together without contradiction.

[0260] In the above embodiments, the information transmission methods executed on the network control repeater side and the access network side can be one-to-one corresponding. Therefore, the same explanations or features will not be repeated one by one, and the corresponding side embodiments can be referred to.

[0261] The following provides a specific example in conjunction with any of the above embodiments:

[0262] P1: In DCI, there are Lmax beam ID fields (i.e., beam identification fields) used to indicate beam identification (ID). The value of Lmax (i.e. N) is configured through the first signaling (indication information of N), for example, Lmax = 8.

[0263] P2: The value of Lmax is not greater than M, where M is the maximum number of beams supported by the access link.

[0264] P3: Each beam ID field can indicate a special value (i.e., a predetermined value) that indicates that the beam ID field does not indicate any valid beam.

[0265] P4: The bit width of each beam ID field and / or the beam ID corresponding to each bit code (i.e., the association between beam indication information and beam identifier) ​​is configured by the base station through the third signaling (first configuration information).

[0266] Example 1: Configure NCR-ap-beam::=[-1, 0, 1, 2, 7, 8] via RRC. When the indicator bit code=0, corresponding to NCR-ap-beam=-1, it means that no valid beam is indicated. When the bit code=2, it corresponds to beam ID#1.

[0267] Example 2: Using a standard predefined method, when the bit code indicates a special value (i.e. a predetermined value), such as all 1s, it means that no valid beam is indicated. Other valid bit code values ​​correspond to beam IDs, such as bit code = 1 corresponding to beam #1, and bit code = 7 corresponding to beam #7.

[0268] P5: When all Lmax domains' beam IDs are not pointing to any beam, the NCR's Fwd function is considered to be dynamically turned off.

[0269] P6: The correspondence between the beam ID domain and the time-domain resource domain is determined by predefined rules. Tmax represents the number of time-domain resource domains.

[0270] When Tmax = Lmax, the beam ID domain and the time domain resource domain have a one-to-one correspondence, for example, L1 corresponds to T1 and L2 corresponds to T2.

[0271] When Tmax = 1, the resources in the time domain are evenly distributed to each beam.

[0272] The order of the steps listed in the above embodiments is not intended to limit the execution order of the steps. Each step can be executed in the order listed, or it can be executed in a different order if there is no contradiction. Each step can be implemented as a separate embodiment if there is no contradiction, or multiple steps can be combined as an embodiment.

[0273] Example 1:

[0274] N=10; there are a total of 10 beams available for the access link.

[0275] RRC configuration: Lmax = 8; There are 8 fields in DCI used to indicate beam ID.

[0276] Bitwidth = 3; Each beam ID field in the DCI configured by RRC has 3 bits to indicate the beam ID; each bit code corresponds to the corresponding beam ID configured by RRC.

[0277] RRC configuration NCR-ap-beam::=SEQUENCE(SIZE(1..8))OF INTEGER(-1..9).

[0278] NCR-ap-beam::=-1, 0, 1, 2, 3, 4, 6, 9

[0279] There are Tmax time-domain resource domains, and Tmax = Lmax. Each time-domain resource domain corresponds one-to-one with the beam ID domain. The meaning of a time-domain resource domain includes: {the offset between the starting slot and the slot for receiving control information, the starting symbol of the time-domain resource in the starting slot, and the number of symbols for the duration of the time-domain resource}.

[0280] The fields in DCI are as follows:

[0281] L1:1, corresponding to beam #0

[0282] L2:4, corresponding to beam #3

[0283] L3:8, corresponding to beam #9

[0284] L4:0, corresponding to -1

[0285] L5:0, corresponding to -1

[0286] L6:0, corresponding to -1

[0287] L7:0, corresponding to -1

[0288] L8:0, corresponding to -1

[0289] T1: {1, 1, 10}

[0290] T2: {2, 6, 2}

[0291] T3: {2, 8, 3}

[0292] T4: {0, 0, 0}

[0293] T5: {0, 0, 0}

[0294] T6: {0, 0, 0}

[0295] T7: {0, 0, 0}

[0296] T8: {0, 0, 0}.

[0297] According to the above representation, the DCI indicates that three beams should be transmitted on the access link of the NCR, with beam IDs of beam #0, 3, and 9 respectively. Assuming that the mobile terminal in the network control receives the DCI in slot #n, then beam #0 is transmitted on symbols 1 to 10 of slot #n+1; beam #3 is transmitted on symbols 6 to 7 of slot #n+2; and beam #9 is transmitted on symbols 8 to 10 of slot #n+2.

[0298] Example 2:

[0299] N=10; there are a total of 10 beams available for access links.

[0300] RRC configuration: Lmax=8; DCI has 8 fields used to indicate beam ID.

[0301] Bitwidth = 4; calculated according to predefined rules, each bit code directly corresponds to the beam ID.

[0302] Predefined rules: There are a total of 10 beams. Considering special states, there are 11 states to represent them. Each of the 11 states requires at least 4 bits. Special states are represented by all 1s.

[0303] There are Tmax time resources, and Tmax = 1. The time resource domain and the beam ID domain correspond one-to-one. The meaning of the time resource domain is as follows: (The domain in the DCI is defined as follows:)

[0304] L1:1, corresponding to beam #1

[0305] L2:4, corresponding to beam #4

[0306] L3:8, corresponding to beam #8

[0307] L4:15 corresponds to a special state, such as being off.

[0308] L5:15 corresponds to a special state, such as being off.

[0309] L6:15 corresponds to a special state, such as being off.

[0310] L7:15 corresponds to a special state, such as being off.

[0311] L8:15 corresponds to a special state, such as being off.

[0312] T1: {1, 1, 3}.

[0313] According to the above representation, the DCI instructs the NCR to transmit three beams on the access link, with beam IDs of beam #1, 4, and 8 respectively. Assuming that the mobile terminal in the network control receives the DCI in slot #n, then beam #1 is transmitted on the first symbol of slot #n+1; beam #4 is transmitted on the second symbol of slot #n+1; and beam #8 is transmitted on the third symbol of slot #n+1.

[0314] like Figure 10 As shown, this exemplary embodiment provides an information transmission device 100, disposed in an access network device, including:

[0315] The transceiver module 110 is configured to send control information carrying N beam identifier fields to the network control repeater, wherein the beam identifier field is used to carry beam indication information for determining the beam identifier of the access link, wherein N is less than or equal to M, and M is the maximum number of beams supported by the access link, wherein at least one of N, the association relationship between the beam indication information and the beam identifier, and the bit width of each beam identifier field is indicated by the first configuration information.
