[0094] The following is a detailed description of a transmission method and apparatus provided in this application, with reference to the accompanying drawings.

[0095] Please see Figure 2 , Figure 2 This is a flowchart illustrating a transmission method provided in an embodiment of this application, applied to a first access network device.

[0096] The transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in the related art.

[0097] like Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0098] Step 201: Send indication information to the terminal device; wherein, the indication information is used to determine a first resource location, the first resource location being a resource location where the terminal device avoids transmitting information.

[0099] The indication information can be higher-layer signaling, such as Radio Resource Control (RRC) signaling, Media Access Control-Control Element (MAC CE) signaling, or physical layer signaling. The higher-layer signaling carries configuration information; this configuration information indicates the first resource location where rate matching or data puncturing is required in the presence of uplink transmission. The presence of uplink transmission at the first resource location can be indicated by being located at that location, or by information configured to require uplink transmission.

[0100] In one possible implementation, the indication information may include first indication information and second indication information; wherein the first indication information is used to indicate a set of pattern information for a first resource location; the second indication information is used to indicate at least one pattern information in the set of pattern information; and the at least one pattern information is used to indicate a first resource location for execution rate matching, or to indicate a first resource location for execution data punching. That is, based on the first indication information, a set of pattern information including at least one pattern information can be determined; based on the second indication information, at least one pattern information in the specific set of pattern information to be used can be determined; and based on the pattern information at the corresponding first resource location, execution rate matching or execution data punching is performed.

[0101] It should be noted that the first instruction information can be sent based on signaling or it can be pre-agreed upon. For details regarding the case where the first instruction information is sent based on signaling, please refer to [link / reference needed]. Figure 5 The relevant descriptions in the corresponding embodiments will not be repeated in this embodiment.

[0102] As one possible implementation, the second instruction information can indicate a first resource location for performing rate matching by indicating at least one pattern information in a set of pattern information specifically used, so that rate matching can be performed at the first resource location; or, the second instruction information can indicate a first resource location for performing data punching by indicating at least one pattern information in a set of pattern information specifically used, so that rate matching can be performed at the first resource location.

[0103] As another possible implementation, the second indication information indicates the first resource location by indicating at least one pattern from a set of pattern information specifically used. The second indication information also includes an indication field for indicating whether the operation to be performed at the first resource location is either data punching or rate matching.

[0104] As another possible implementation, the second indication information indicates the first resource location by indicating at least one pattern from the set of pattern information specifically used. The second indication information also includes an indication field for indicating whether either data puncturing or rate matching needs to be performed at the first resource location. That is, data puncturing or rate matching is not required at every first resource location, but can be performed only at a subset of the first resource locations.

[0105] As a second possible implementation, the indication information may include third indication information; wherein the third indication information is used to indicate pattern information for determining the first resource location; further, the indication information may also include fourth indication information, used to indicate whether rate matching or data puncturing should be performed at the first resource location determined by the pattern information. That is, the first resource location is determined based on a pattern information indicated by the third indication information, and the fourth indication information can determine whether rate matching or data puncturing needs to be performed at the first resource location. In other words, data puncturing or rate matching is not required at every first resource location, but can be performed only at some first resource locations. The pattern information indicated by the third indication information may be pattern information from a pattern information set, which may be pre-configured, i.e., agreed upon by a protocol, or configured on the network side.

[0106] The indication information also includes one of the following: information indicating that the operation performed by the terminal device at the first resource location is rate matching, or information indicating that the operation performed by the terminal device at the first resource location is data puncturing. In other words, the indication information can determine whether the operation performed at the first resource location is data puncturing or rate matching.

[0107] The first resource location can be a time-domain resource location and / or a frequency-domain resource location. That is, the first resource location can be a time-domain resource location, a frequency-domain resource location, or a combination of both.

[0108] In the transmission method of this application embodiment, a first access network device sends indication information to a terminal device; wherein, the indication information is used to determine a first resource location, the first resource location being a resource location where the terminal device avoids transmitting information, and the first resource location is determined according to the indication information to avoid the terminal device transmitting information at the first resource location, thereby avoiding cross-interference.

[0109] Please see Figure 3 , Figure 3 This is a flowchart illustrating another transmission method provided in an embodiment of this application, applied to a first access network device.

[0110] The transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in the related art.

[0111] like Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0112] Step 301: Send indication information to the terminal device; wherein, the indication information is used to determine a first resource location, the first resource location being a resource location where the terminal device avoids transmitting information.

[0113] The first resource location can be a time-domain resource location and / or a frequency-domain resource location. That is, the first resource location can be a time-domain resource location, a frequency-domain resource location, or a combination of both.

[0114] Step 302: Obtain configuration information for interference measurement; wherein the configuration information is used to determine at least one of the following: sequence information of the pilots of the second access network device; period of interference measurement; first resource location; wherein the first resource location is used to perform interference measurement on the second access network device.

[0115] The pilot sequence information of the second access network device is used for reference signal demodulation. The first resource location refers to the resource location occupied when the reference signal is transmitted.

[0116] The interference measurement period refers to the interval between the first access network device and the second access network device performing interference measurements. Specifically, the interference measurement period can be indicated by the second access network device to the first access network device.

[0117] In this embodiment of the application, the process by which the first access network device obtains the configuration information for interference measurement can be, for example, by receiving configuration information sent by the second access network device through the communication interface between the first access network device and the second access network device; or by receiving configuration information sent by the core network device; or by receiving configuration information sent by the second access network device through a terminal device that communicates with both the second access network device and the first access network device.

[0118] The second access network device and the first access network device can communicate with the same terminal device. The second access network device can send configuration information to the terminal device, and the terminal device will forward the received configuration information to the first access network device. That is, the configuration information can be relayed through the terminal device.

[0119] The first access network device can be the target base station, and the second access network device can be the base station.

[0120] The transmission method of this application embodiment includes a first access network device sending indication information to a terminal device; wherein the indication information is used by the terminal device to determine a first resource location, which is a resource location where the terminal device avoids transmitting information; and to obtain configuration information for interference measurement; wherein the configuration information is used to determine at least one of the following: the sequence information of the pilots of the second access network device; the period of interference measurement; and the first resource location; wherein the first resource location is used to perform interference measurement on the second access network device, avoid the terminal device from transmitting information at the first resource location, thereby avoiding cross-interference between access network devices and ensuring the accuracy of interference measurement.

[0121] Please see Figure 4 , Figure 4 This is a flowchart illustrating another transmission method provided in an embodiment of this application, applied to a first access network device.

[0122] The transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in the related art.

[0123] like Figure 4 As shown, the method may include, but is not limited to, the following steps:

[0124] Step 401: Send indication information to the terminal device; wherein, the indication information is used to determine the first resource location, and the indication information is configuration information; the configuration information is used to indicate the first resource location where rate matching or data puncturing is required when there is uplink transmission.

[0125] The presence of uplink transmission at the first resource location could mean that uplink transmission has been indicated or that information has been configured to require uplink transmission.

[0126] The first resource location is the resource location where the terminal device avoids transmitting information. The first resource location is used for interference measurement of the second access network device.

[0127] The configuration information is used to determine at least one of the following: the sequence information of the pilots of the second access network device; the period of interference measurement; and the location of the first resource.

[0128] The first resource location can be a time-domain resource location and / or a frequency-domain resource location. That is, the first resource location can be a time-domain resource location, a frequency-domain resource location, or a combination of both.

[0129] In this embodiment of the application, the first network access device can send higher-layer instructions to the terminal device, such as Radio Resource Control (RRC) signaling, Media Access Control-Control Element (MAC CE) signaling, and physical layer signaling. The higher-layer instructions carry configuration information for interference measurement, which is used to determine whether the terminal device performs rate matching or data punching at the first resource location.

[0132] This transmission method can be executed alone, or it can be executed in conjunction with any embodiment of this disclosure or possible implementations within the embodiments, or it can be executed in conjunction with any technical solution in related technologies. For example, Figure 5 The embodiments can be combined with Figure 6 The embodiments described can be executed together.

[0133] like Figure 5 As shown, the method may include, but is not limited to, the following steps:

[0134] Step 501: Send indication information to the terminal device; wherein the indication information is used to determine the first resource location, and the indication information includes first indication information and second indication information; wherein the first indication information is used to indicate the pattern information set of the first resource location; the second indication information is used to indicate at least one pattern information in the pattern information set; at least one pattern information is used to indicate the first resource location for execution rate matching, or to indicate the first resource location for execution data punching.

[0135] It should be noted that the first indication information can be sent based on signaling or it can be pre-agreed upon. For details regarding the case where the first indication information is sent based on signaling, please refer to the relevant description in this embodiment.

[0136] As one possible implementation, the first indication information and the second indication information can be sent through a single signaling message, and the first and second indication information can correspond to different indication fields of the signaling message. The signaling message can be higher-layer signaling, such as RRC signaling, MAC CE signaling, or physical layer signaling.

[0137] As another possible implementation, the first indication information and the second indication information can be sent through different signaling. That is, the first indication information can be sent through the first signaling, and the second indication information can be sent through the second signaling. The first signaling can be RRC signaling, MAC CE signaling, or physical layer signaling, and the second signaling can be a scheduling instruction.

[0138] The first access network device can first send a first signaling to the terminal device. The first signaling carries information about a set of pattern information that determines the location of the first resource. The set of pattern information may include information about at least one pattern. The first access network device can then send a second signaling, namely a scheduling instruction, to the terminal device. The second signaling includes a fixed information field or a configurable information field. It can determine a pattern based on information about at least one pattern in the set of pattern information. Based on the pattern information, it determines that the terminal device can perform rate matching or data punching at the first resource location.

[0139] Specifically, a set of pattern information including at least one pattern information can be determined based on the first instruction information, and at least one pattern information in the specific set of pattern information can be determined based on the second instruction information. Based on the pattern information at the corresponding first resource location, rate matching is performed, or data punching is performed.

[0140] As one possible implementation, the second instruction information can indicate a first resource location for performing rate matching by indicating at least one pattern information in a set of pattern information specifically used, so that rate matching can be performed at the first resource location; or, the second instruction information can indicate a first resource location for performing data punching by indicating at least one pattern information in a set of pattern information specifically used, so that rate matching can be performed at the first resource location.

[0141] As another possible implementation, the second indication information indicates the first resource location by indicating at least one pattern from a set of pattern information specifically used. The second indication information also includes an indication field for indicating whether the operation to be performed at the first resource location is either data punching or rate matching.

[0142] As another possible implementation, the second indication information indicates the first resource location by indicating at least one pattern from the set of pattern information specifically used. The second indication information also includes an indication field for indicating whether either data puncturing or rate matching needs to be performed at the first resource location. That is, data puncturing or rate matching is not required at every first resource location, but can be performed only at a subset of the first resource locations.

[0143] The first resource location is the resource location where the terminal device avoids transmitting information. The first resource location is used for interference measurement of the second access network device.

[0144] The first resource location can be a time-domain resource location and / or a frequency-domain resource location. That is, the first resource location can be a time-domain resource location, a frequency-domain resource location, or a combination of both.

[0145] In the transmission method of this application embodiment, a first access network device sends indication information to a terminal device; wherein, the indication information is used by the terminal device to determine a first resource location, and the indication information includes first indication information and second indication information; wherein, the first indication information is used to indicate information of a pattern information set of the first resource location; the second indication information is used to indicate information of at least one pattern information in the pattern information set; at least one pattern information is used to indicate the first resource location for execution rate matching, or to indicate the first resource location for execution data puncturing, so as to avoid the terminal device transmitting information at the first resource location, thereby avoiding cross-interference between access network devices and ensuring the accuracy of interference measurement.

[0146] Please see Figure 6 , Figure 6This is a flowchart illustrating another transmission method provided in an embodiment of this application, applied to a first access network device.

[0147] This transmission method can be executed alone, or it can be executed in conjunction with any embodiment of this disclosure or possible implementations within the embodiments, or it can be executed in conjunction with any technical solution in related technologies.

[0150] The indication information also includes a fourth indication information; wherein the fourth indication information is used to indicate whether to perform rate matching or data punching at the first resource location determined by the pattern information.

[0151] In other words, the first resource location is determined based on a pattern information indicated by the third instruction, and the fourth instruction determines whether rate matching or data punching needs to be performed at the first resource location. That is, data punching or rate matching is not required at every first resource location; it can be performed only at some of the first resource locations.

[0152] The pattern information indicated by the third instruction information can be pattern information in a pattern information set. The pattern information set can be pre-configured, that is, it can be agreed upon by a protocol, or it can be configured by the network side.

[0153] The first resource location is the resource location where the terminal device avoids transmitting information. The first resource location is used for interference measurement of the second access network device.

[0154] The first resource location can be a time-domain resource location and / or a frequency-domain resource location. That is, the first resource location can be a time-domain resource location, a frequency-domain resource location, or a combination of both.

[0155] As one possible implementation, the third and fourth indication information can be sent through a single signaling message, and the third and fourth indication information can correspond to different indication fields of the signaling message. The signaling message can be higher-level signaling, such as RRC signaling, MAC CE signaling, or physical layer signaling.

[0156] As another possible implementation, the third and fourth indication information can be sent through different signaling, that is, the third indication information can be sent through the third signaling and the fourth indication information can be sent through the fourth signaling. The first signaling can be RRC signaling, MAC CE signaling, or physical layer signaling, and the second signaling can be a scheduling instruction.

[0157] The first access network device can first send a third signaling to the terminal device, which carries pattern information that determines the location of the first resource. The first access network device can then send a fourth signaling, namely a scheduling instruction, to the terminal device. The fourth signaling includes a fixed information field or a configurable information field, indicating whether to perform rate matching at the location of the first resource determined by the pattern information, or indicating whether to perform data punching at the location of the first resource determined by the pattern information.

[0158] The transmission method of this application embodiment involves a first access network device sending indication information to a terminal device; wherein the indication information is used by the terminal device to determine a first resource location, and the indication information includes third indication information; wherein the third indication information is used to indicate pattern information of the first resource location; this avoids the terminal device transmitting information at the first resource location, thereby avoiding cross-interference between access network devices and ensuring the accuracy of interference measurement.

[0163] In other words, based on the instruction information, it can be determined that the operation performed by the terminal device at the first resource location is either data punching or rate matching.

[0164] As one possible implementation, the indication information includes an information field, which can be used to determine whether the operation performed by the terminal device at the first resource location is rate matching or data punching.

[0165] The first resource location is the resource location where the terminal device avoids transmitting information. The first resource location is used for interference measurement of the second access network device.

[0166] The first resource location can be a time-domain resource location and / or a frequency-domain resource location. That is, the first resource location can be a time-domain resource location, a frequency-domain resource location, or a combination of both.

[0167] In this embodiment, the first access network device sends a scheduling instruction to the terminal device. This scheduling instruction includes an information field, which can instruct the terminal device to perform either rate matching or data puncturing at a first resource location. The information field can be a fixed field or a configurable field.

[0168] In the transmission method of this application embodiment, a first access network device sends indication information to a terminal device; wherein, the indication information is used by the terminal device to determine a first resource location, and the indication information includes an information field; the information field is used to indicate that the operation performed by the terminal device at the first resource location is rate matching, or to indicate that the operation performed by the terminal device at the first resource location is data puncturing, so as to avoid the terminal device transmitting information at the first resource location, thereby avoiding cross-interference between access network devices and ensuring the accuracy of interference measurement.

[0172] Step 801: Receive the indication information sent by the first access network device.

[0173] The indication information can be higher-layer signaling, such as Radio Resource Control (RRC) signaling, Media Access Control-Control Element (MAC CE) signaling, or physical layer signaling. The higher-layer instructions carry configuration information; this configuration information indicates the first resource location where rate matching or data puncturing is required in the presence of uplink transmission. The presence of uplink transmission at the first resource location can be indicated by being located at that location, or by information configured to require uplink transmission.

[0174] In a first possible implementation, the indication information may include first indication information and second indication information; wherein the first indication information is used to indicate a set of pattern information for a first resource location; the second indication information is used to indicate at least one pattern information in the set of pattern information; the at least one pattern information is used to indicate a first resource location for execution rate matching, or to indicate a first resource location for execution data punching. That is, based on the first indication information, a set of pattern information including at least one pattern information can be determined; based on the second indication information, at least one pattern information in the specific set of pattern information to be used can be determined; and based on the pattern information at the corresponding first resource location, execution rate matching or execution data punching is performed.

[0175] It should be noted that the first instruction information can be sent based on signaling or it can be pre-agreed upon. For details regarding the case where the first instruction information is sent based on signaling, please refer to [link / reference needed]. Figure 11 The relevant descriptions in the corresponding embodiments will not be repeated in this embodiment.

[0176] As one possible implementation, the second instruction information can indicate a first resource location for performing rate matching by indicating at least one pattern information in a set of pattern information specifically used, so that rate matching can be performed at the first resource location; or, the second instruction information can indicate a first resource location for performing data punching by indicating at least one pattern information in a set of pattern information specifically used, so that rate matching can be performed at the first resource location.

The second indication information also includes an indication field for indicating whether the operation to be performed at the first resource location is either data punching or rate matching.

[0178] As another possible implementation, the second indication information indicates the first resource location by indicating at least one pattern from the set of pattern information specifically used. The second indication information also includes an indication field for indicating whether either data puncturing or rate matching needs to be performed at the first resource location. That is, data puncturing or rate matching is not required at every first resource location, but can be performed only at a subset of the first resource locations.

[0179] As a second possible implementation, the indication information may include third indication information; wherein the third indication information is used to indicate pattern information of the first resource location; further, the indication information may also include fourth indication information, used to indicate whether rate matching or data puncturing should be performed at the first resource location determined by the pattern information. That is, the first resource location is determined based on a pattern information indicated by the third indication information, and the fourth indication information can determine whether rate matching or data puncturing needs to be performed at the first resource location. In other words, data puncturing or rate matching is not required at every first resource location, but can be performed only at some first resource locations. The pattern information indicated by the third indication information may be pattern information from a pattern information set, which may be pre-configured, i.e., agreed upon by a protocol, or configured on the network side.

[0180] The indication information also includes one of the following: information indicating that the operation performed by the terminal device at the first resource location is rate matching, or information indicating that the operation performed by the terminal device at the first resource location is data puncturing. In other words, the indication information can determine whether the operation performed at the first resource location is data puncturing or rate matching.

[0182] The first access network device can be the target base station.

[0183] Step 802: Based on the indication information, avoid transmitting information at the first resource location in the uplink transmission.

[0184] In the transmission method of this application embodiment, the terminal device receives indication information sent by the first access network device; based on the indication information, it avoids transmitting information at the first resource location in the uplink transmission, thereby avoiding cross-interference between access network devices.

[0185] Please see Figure 9 , Figure 9 This is a flowchart illustrating another transmission method provided in an embodiment of this application, applied to a terminal device.

[0186] The transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in the related art.

[0187] like Figure 9 As shown, the method may include, but is not limited to, the following steps:

[0188] Step 901: Receive indication information sent by the first access network device, wherein the indication information is generated by the first access network device based on configuration information of interference measurement; wherein the configuration information is used to determine at least one of the following: sequence information of pilots of the second access network device; period of interference measurement; first resource location.

[0189] The pilot sequence information of the second access network device is used for reference signal demodulation. The first resource location refers to the resource location occupied when the reference signal is transmitted.

[0190] The interference measurement period refers to the interval between the first access network device and the second access network device performing interference measurements. Specifically, the interference measurement period can be indicated by the second access network device to the first access network device.

[0191] The first access network device can be the target base station, and the second access network device can be the base station.

[0192] Step 902: Based on the indication information, avoid transmitting information at the first resource location in the uplink transmission.

[0193] The first resource location can be a time-domain resource location and / or a frequency-domain resource location. That is, the first resource location can be a time-domain resource location, a frequency-domain resource location, or a combination of both.

[0194] In one possible implementation of this application, the terminal device avoids transmitting information at a first resource location in the uplink transmission based on indication information, which can be achieved by performing rate matching at the first resource location in the uplink transmission. In another possible implementation, the terminal device avoids transmitting information at a first resource location in the uplink transmission based on indication information, which can be achieved by performing data puncturing at the first resource location in the uplink transmission.

[0195] In the transmission method of this application embodiment, the terminal device receives indication information sent by the first access network device; based on the indication information, it avoids transmitting information at the first resource location in the uplink transmission, thereby avoiding cross-interference between access network devices and ensuring the accuracy of interference measurement.

[0196] Please see Figure 10 , Figure 10 This is a flowchart illustrating another transmission method provided in an embodiment of this application, applied to a terminal device.

[0197] The transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in the related art.

[0198] like Figure 10 As shown, the method may include, but is not limited to, the following steps:

[0199] Step 1001: Receive indication information sent by the first access network device, wherein the indication information is configuration information.

[0200] The configuration information is used to determine at least one of the following: the sequence information of the pilots of the second access network device; the period of interference measurement; and the location of the first resource.

[0201] The pilot sequence information of the second access network device is used for reference signal demodulation. The first resource location refers to the resource location occupied when the reference signal is transmitted.

[0202] The interference measurement period represents the interval between the first access network device and the second access network device performing interference measurements. This interference measurement period can be indicated by the second access network device to the first access network device. The first access network device can be the target base station, and the second access network device can be the base station.

[0203] In this embodiment of the application, the terminal device can receive higher-layer signaling sent by the first access network device, such as RRC signaling, MAC CE signaling, and physical layer signaling. The higher-layer instruction carries configuration information for interference measurement, which is used to instruct the execution of rate matching at the first resource location or to perform data puncturing.

[0204] Step 1002: Determine the location of the first resource based on the configuration information.

[0205] The first resource location can be a time-domain resource location and / or a frequency-domain resource location. That is, the first resource location can be a time-domain resource location, a frequency-domain resource location, or a combination of both.

[0206] Step 1003: If it is determined that there is uplink transmission at the first resource location, perform rate matching at the first resource location, or perform data punching.

[0207] In this embodiment of the application, when the terminal device determines that there is uplink transmission at the first resource location, that is, when it is indicated at the first resource location or when it is configured to perform uplink transmission, it can perform rate matching at the first resource location or perform data punching at the first resource location. That is, when it is determined that there is uplink transmission at the first resource location, the terminal device is prevented from transmitting information at the first resource location.

[0208] The transmission method of this application embodiment includes a terminal device receiving indication information sent by a first access network device, wherein the indication information is configuration information; determining a first resource location based on the configuration information; and performing rate matching or data puncturing at the first resource location if uplink transmission is determined to exist there is uplink transmission at the first resource location, thereby avoiding information transmission at the first resource location during uplink transmission, avoiding cross-interference between access network devices, and ensuring the accuracy of interference measurement.

[0209] Please see Figure 11 , Figure 11 This is a flowchart illustrating another transmission method provided in an embodiment of this application, applied to a terminal device.

[0210] This transmission method can be executed alone, or it can be executed in conjunction with any embodiment of this disclosure or possible implementations within the embodiments, or it can be executed in conjunction with any technical solution in related technologies. For example, Figure 11 Implementation examples can be combined Figure 12 The implementation examples can be executed together.

[0211] like Figure 11 As shown, the method may include, but is not limited to, the following steps:

[0212] Step 1101: Receive indication information sent by the first access network device, wherein the indication information includes first indication information and second indication information; wherein the first indication information is used to indicate the pattern information set of the first resource location; the second indication information is used to indicate at least one pattern information in the pattern information set, and at least one pattern information is used to indicate the first resource location for execution rate matching, or to indicate the first resource location for execution data punching.

[0213] It should be noted that the first indication information can be sent based on signaling or it can be pre-agreed upon. For details regarding the case where the first indication information is sent based on signaling, please refer to the relevant description in this embodiment.

[0214] As one possible implementation, the first indication information and the second indication information can be sent through a single signaling message, and the first and second indication information can correspond to different indication fields of the signaling message. The signaling message can be higher-layer signaling, such as RRC signaling, MAC CE signaling, or physical layer signaling.

[0215] As another possible implementation, the first indication information and the second indication information can be sent through different signaling. That is, the first indication information can be sent through the first signaling, and the second indication information can be sent through the second signaling. The first signaling can be RRC signaling, MAC CE signaling, or physical layer signaling, and the second signaling can be a scheduling instruction.

[0216] The first access network device can first send a first signaling to the terminal device. The first signaling carries information about a set of pattern information that determines the location of the first resource. The set of pattern information may include information about at least one pattern. The first access network device can then send a second signaling, namely a scheduling instruction, to the terminal device. The second signaling includes a fixed information field or a configurable information field. It can determine a pattern based on information about at least one pattern in the set of pattern information. Based on the pattern information, it determines that the terminal device can perform rate matching or data punching at the first resource location.

[0217] In other words, based on the first instruction information, a set of pattern information including at least one pattern information can be determined; based on the second instruction information, at least one pattern information in the set of pattern information to be used can be determined; and based on the pattern information at the corresponding first resource location, rate matching or data punching is performed.

[0218] As one possible implementation, the second instruction information can indicate a first resource location for performing rate matching by indicating at least one pattern information in a set of pattern information specifically used, so that rate matching can be performed at the first resource location; or, the second instruction information can indicate a first resource location for performing data punching by indicating at least one pattern information in a set of pattern information specifically used, so that rate matching can be performed at the first resource location.

[0219] As another possible implementation, the second indication information indicates the first resource location by indicating at least one pattern from a set of pattern information specifically used. The second indication information also includes an indication field for indicating whether the operation to be performed at the first resource location is either data punching or rate matching.

[0220] As another possible implementation, the second indication information indicates the first resource location by indicating at least one pattern from the set of pattern information specifically used. The second indication information also includes an indication field for indicating whether either data puncturing or rate matching needs to be performed at the first resource location. That is, data puncturing or rate matching is not required at every first resource location, but can be performed only at a subset of the first resource locations.

[0221] The first access network device can be the target base station, and the second access network device can be the base station.

[0222] The first resource location can be a time-domain resource location and / or a frequency-domain resource location. That is, the first resource location can be a time-domain resource location, a frequency-domain resource location, or a combination of both.

[0223] Step 1102: Based on the indication information, avoid transmitting information at the first resource location in the uplink transmission.

[0224] In one possible implementation of this application, the terminal device avoids transmitting information at a first resource location in the uplink transmission based on indication information, which can be achieved by performing rate matching at the first resource location in the uplink transmission. In another possible implementation, the terminal device avoids transmitting information at a first resource location in the uplink transmission based on indication information, which can be achieved by performing data puncturing at the first resource location in the uplink transmission.

[0225] The transmission method of this application embodiment includes a terminal device receiving indication information sent by a first access network device. The indication information includes first indication information and second indication information. The first indication information indicates a set of pattern information for a first resource location. The second indication information indicates at least one pattern information in the pattern information set. The at least one pattern information indicates either a first resource location for rate matching or a first resource location for data puncturing. Based on the indication information, information is avoided at the first resource location in uplink transmission, thereby avoiding cross-interference between access network devices and ensuring the accuracy of interference measurement.

[0226] Please see Figure 12 , Figure 12 This is a flowchart illustrating another transmission method provided in an embodiment of this application, applied to a terminal device.

[0229] Step 1201: Receive indication information sent by the first access network device, wherein the indication information includes third indication information; wherein the third indication information is information used to indicate the pattern information of the first resource location.

[0230] The indication information also includes a fourth indication information, which is used to indicate whether the terminal device performs rate matching or data punching at the first resource location determined by the pattern information.

[0231] The pattern information indicated by the third instruction information can be pattern information in a pattern information set. The pattern information set can be pre-configured, that is, it can be agreed upon by a protocol, or it can be configured by the network side.

[0232] As one possible implementation, the third and fourth indication information can be sent through a single signaling message, and the third and fourth indication information can correspond to different indication fields of the signaling message. The signaling message can be higher-level signaling, such as RRC signaling, MAC CE signaling, or physical layer signaling.

[0233] As another possible implementation, the third and fourth indication information can be sent through different signaling, that is, the third indication information can be sent through the third signaling and the fourth indication information can be sent through the fourth signaling. The first signaling can be RRC signaling, MAC CE signaling, or physical layer signaling, and the second signaling can be a scheduling instruction.

[0234] The terminal device can receive a third signaling sent by the first access network device, which carries pattern information that determines the location of the first resource. The terminal device can also receive a fourth signaling, namely a scheduling instruction, sent by the first access network device. The fourth signaling includes a fixed information field or a configurable information field, indicating whether to perform rate matching at the first resource location determined by the pattern information, or indicating whether to perform data punching at the first resource location indicated by the pattern information.

[0235] In other words, the first resource location can be determined based on the third indication information, and whether the terminal device needs to perform rate matching or data puncturing at the first resource location can be determined based on the fourth indication information. That is, data puncturing or rate matching does not need to be performed at every first resource location, but only at some first resource locations.

[0236] The first access network device can be the target base station, and the second access network device can be the base station.

[0237] The first resource location can be a time-domain resource location and / or a frequency-domain resource location. That is, the first resource location can be a time-domain resource location, a frequency-domain resource location, or a combination of both.

[0238] Step 1202: Based on the indication information, avoid transmitting information at the first resource location in the uplink transmission.

[0239] In one possible implementation of this application, the terminal device avoids transmitting information at a first resource location in the uplink transmission based on indication information, which can be achieved by performing rate matching at the first resource location in the uplink transmission. In another possible implementation, the terminal device avoids transmitting information at a first resource location in the uplink transmission based on indication information, which can be achieved by performing data puncturing at the first resource location in the uplink transmission.

[0240] The transmission method of this application embodiment includes a terminal device receiving indication information sent by a first access network device. The indication information includes third indication information and fourth indication information. The third indication information is used to indicate pattern information of a first resource location. The fourth indication information is used to indicate whether the terminal device should perform rate matching or data puncturing at the first resource location determined by the pattern information. Based on the indication information, information transmission is avoided at the first resource location in uplink transmission, thereby avoiding cross-interference between access network devices and ensuring the accuracy of interference measurement.

[0241] Please see Figure 13 , Figure 13 This is a flowchart illustrating another transmission method provided in an embodiment of this application, applied to a terminal device.

[0242] The transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in the related art.

[0245] In other words, based on the instruction information, it can be determined that the operation performed at the first resource location is either data punching or rate matching.

[0246] As one possible implementation, the indication information includes an information field, which can be used to determine whether the operation performed by the terminal device at the first resource location is rate matching or data punching.
