Technical Field

[0001] The present application relates to the field of communication technology, and in particular to communication methods and devices. Background Art

[0002] In a communication system, a network device may indicate one or more physical uplink shared channel (PUSCH) resources to a terminal device, and the network device may receive one or more uplink information from the terminal device on the one or more PUSCH resources.

[0003] However, the above one or more PUSCH resources may overlap with other resources, for example, with random access resources, so that the network device may receive uplink information of one terminal device and random access message of another terminal device at the same time on the overlapping resources. If the network device does not have the ability to receive in parallel, it will cause reception failure and affect communication performance.

[0004] Therefore, how to ensure communication reliability and improve communication performance has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The embodiments of the present application provide a communication method and apparatus, which can ensure that network equipment can achieve uplink reception, thereby ensuring communication reliability and improving communication performance.

[0006] In a first aspect, a communication method is provided, which can be executed by a terminal device. Unless otherwise specified, the "terminal device" in this application can refer to the terminal device itself, or a component in the terminal device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can implement all or part of the functions of the terminal device. The method includes: the terminal device sends a first indication information; sends a first message. The first indication information is used to indicate the ability of the terminal device to avoid a second resource when sending the first information on the first resource; the second resource is a resource in the first resource that overlaps with a third resource.

[0007] Based on this solution, the terminal device sends the first indication information to the network device, which can enable the network device to determine whether the terminal device supports avoiding the second resource when sending the first information on the first resource, and can enable the network device to coordinate with the terminal device to transmit the resources of the first information based on the first indication information, thereby avoiding the network device from receiving the first information and other information (the other information is the information transmitted on the third resource) on overlapping resources as much as possible, thereby ensuring communication reliability and improving communication performance.

[0008] In a possible implementation, the terminal device receives second indication information; wherein, the second indication information is used to indicate that the terminal device is allowed to send the first indication information.

[0009] Based on this possible implementation, the terminal device can determine, according to the second indication information, that the network device can parse the first indication information, which can avoid, as much as possible, the situation where the terminal device sends the first indication information to the network device but the network device does not parse the first indication information, ensure that the first indication information sent by the terminal device can be parsed by the network device, avoid, as much as possible, the situation of communication failure caused by misalignment between the network device and the terminal device, and improve the efficiency of information interaction between the network device and the terminal device.

[0010] In a possible implementation, when the first indication information indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource, the terminal device sends the first information only on the resources in the first resource other than the second resource.

[0011] Based on this possible implementation, the terminal device can directly send the first information on the resources in the first resource other than the second resource without the network device additionally indicating other information, which can reduce the transmission overhead. At the same time, it can ensure, as much as possible, that when the network device receives the first information, it is not interfered by other information (the other information is the information transmitted on the third resource), improve the reliability of communication, and thus improve the communication performance.

[0012] In a possible implementation, when the first indication information indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource, the terminal device receives third indication information; sends the first information only on the resources in the first resource other than the second resource; wherein, the third indication information is used to indicate that the terminal device avoids the second resource when sending the first information on the first resource; or, the terminal device receives third indication information; sends the first information on the first resource; wherein, the third indication information is used to indicate that the terminal device does not avoid the second resource when sending the first information on the first resource.

[0013] Based on this possible implementation, the network device can indicate the resources for the terminal device to send the first information according to the actual communication situation, which can improve the flexibility of determining the resources for sending the first information. On the one hand, the third indication information can indicate that the terminal device avoids the second resource when sending the first information, and the terminal device can send the first information on the resources other than the second resource in the first resource, so as to ensure that the network device is not interfered by other information (the other information is the information transmitted on the third resource) when receiving the first information as much as possible, which can improve the reliability of communication and thus improve the communication performance; on the other hand, the third indication information can indicate that the terminal device does not avoid the second resource when sending the first information, which can reduce the operation complexity of the terminal device for sending the first information to improve the working efficiency of the terminal device and is more friendly to the implementation of the terminal device.

[0014] In a possible implementation, when the first indication information indicates that the terminal device does not support avoiding the second resource when sending the first information on the first resource, the terminal device receives the fourth indication information and sends the first information on the fourth resource. Wherein, the fourth indication information is used to indicate the fourth resource, and the fourth resource is a resource that does not overlap with the third resource.

[0015] Based on this possible implementation, the terminal device can send the first information on the fourth resource, which can ensure that the network device is not interfered by other information (the other information is the information transmitted on the third resource) when receiving the first information on the fourth resource as much as possible, which can improve the reliability of communication and thus improve the communication performance.

[0016] In a possible implementation, when the first indication information indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource, the terminal device sends the first information on the first resource when the terminal device does not receive the third indication information; or the terminal device only sends the first information on the resources other than the second resource in the first resource. Wherein, the third indication information is used to indicate whether the terminal device avoids the second resource when sending the first information on the first resource.

[0017] Based on this possible implementation, on the one hand, when the terminal device is not sure whether the network device parses the first indication information, when the terminal device does not receive the third indication information, the terminal device can send the first information on the first resource so that the terminal device and the network device are aligned, that is, the network device can receive the first information on the first resource, which can ensure the normal communication between the network device and the terminal device; on the other hand, when the terminal device can determine that the network device parses the first indication information, the terminal device can directly send the first information on the resources other than the second resource in the first resource, which can ensure that the network device is not interfered by other information when receiving the first information as much as possible, which can improve the reliability of communication and thus improve the communication performance.

[0018] In a second aspect, a communication method is provided, which can be executed by a network device. Unless otherwise specified, the "network device" in this application can refer to the network device itself, or a component in the network device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can implement all or part of the functions of the network device (for example, a centralized unit (CU), a distributed unit (DU), or a radio unit (RU), etc.). The method includes: the network device receives a first indication message; receives the first information. The first indication message is used to indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource; the second resource is a resource in the first resource that overlaps with the third resource.

[0019] Based on this solution, the network device receives the first indication information from the terminal device, the network device can determine whether the terminal device supports avoiding the second resource when sending the first information on the first resource, the network device can coordinate with the terminal device to transmit the resource of the first information based on the first indication information, the network device can avoid receiving the first information and other information (the other information is the information transmitted on the third resource) on overlapping resources as much as possible, which can improve the reliability of communication and thus improve communication performance.

[0020] In a possible implementation, the network device sends a second indication information; wherein the second indication is used to indicate that the terminal device is allowed to send the first indication information.

[0021] Based on this possible implementation, the network device sends the second indication information to the terminal device, which can enable the terminal device to determine, based on the second indication information, that the network device is able to parse the first indication information. This can avoid as much as possible the situation where the terminal device sends the first indication information to the network device but the network device does not parse the first indication information, and ensure that the first indication information sent by the terminal device can be parsed by the network device. This can avoid as much as possible the situation where communication failures are caused by misalignment between the network device and the terminal device, and can improve the efficiency of information interaction between the network device and the terminal device.

[0022] In a possible implementation, when the first indication information indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource, the network device receives the first information only on resources other than the second resource in the first resource.

[0023] Based on this possible implementation, the network device can default that the terminal device sends the first information on the resources in the first resource other than the second resource. The network device does not need to additionally indicate other information, which can reduce the transmission overhead. At the same time, it can ensure as much as possible that when the network device receives the first information, it is not interfered by other information (the other information is the information transmitted on the third resource), which can improve the reliability of communication and thus improve the communication performance.

[0024] In a possible implementation, when the first indication information indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource, the network device sends the third indication information; and receives the first information only on the resources in the first resource other than the second resource; wherein, the third indication information is used to indicate that the terminal device avoids the second resource when sending the first information on the first resource; or, the network device sends the third indication information; and receives the first information on the first resource; wherein, the third indication information is used to indicate that the terminal device does not avoid the second resource when sending the first information on the first resource.

[0025] Based on this possible implementation, the network device can indicate the resources for the terminal device to send the first information according to the actual communication situation, which can improve the flexibility of determining the resources for sending the first information. On the one hand, the third indication information can indicate that the terminal device avoids the second resource when sending the first information, and the terminal device can send the first information on the resources in the first resource other than the second resource to ensure as much as possible that when the network device receives the first information, it is not interfered by other information (the other information is the information transmitted on the third resource), which can improve the reliability of communication and thus improve the communication performance; on the other hand, the third indication information can indicate that the terminal device does not avoid the second resource when sending the first information, which can reduce the operation complexity of the terminal device for sending the first information to improve the working efficiency of the terminal device and is more friendly to the implementation of the terminal device.

[0026] In a possible implementation, when the first indication information indicates that the terminal device does not support avoiding the second resource when sending the first information on the first resource, the network device sends the fourth indication information; and receives the first information on the fourth resource. Wherein, the fourth indication information is used to indicate the fourth resource; the fourth resource is a resource that does not overlap with the third resource.

[0027] Based on this possible implementation, it can ensure as much as possible that when the network device receives the first information on the fourth resource, it is not interfered by other information (the other information is the information transmitted on the third resource), which can improve the reliability of communication and thus improve the communication performance.

[0028] In a possible implementation, when the first indication information indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource, and the network device does not parse the first indication information, the network device receives the first information on the first resource; or, when the network device parses the first indication information, the network device receives the first information only on the resources other than the second resource in the first resource.

[0029] Based on this possible implementation, on the one hand, there may be a situation where the network device does not parse the first indication information. When the network device does not parse the third indication information, the network device is unsure whether the terminal device supports avoiding the second resource when sending the first information on the first resource. The network device can receive the first information on the first resource. At the same time, since the terminal device does not receive the third indication information, it can send the first information on the first resource, which can align the terminal device and the network device, and thus ensure normal communication between the network device and the terminal device. On the other hand, if the network device does not have a situation where it does not parse the first indication information, the network device can not send the third indication information to the terminal device. The network device can directly receive the first information on the resources other than the second resource in the first resource, which can ensure that the network device is not interfered by other information when receiving the first information as much as possible, improve the reliability of communication, and thus improve the communication performance.

[0030] Combining the first aspect and the second aspect, in a possible implementation, the first indication information is located in the first message; where the first message is one or more of the following: random access message three, random access message B.

[0031] Combining the first aspect and the second aspect, in a possible implementation, the first indication information is carried in the sub-header of the media access control (MAC) protocol data unit (PDU) in the first message.

[0032] Based on this possible implementation, the first indication information can be located in the above two possible messages, and the position of the first indication information in the first message can be more specifically determined, providing a feasible solution for the implementation of the first indication information.

[0033] Combining the first aspect and the second aspect, in a possible implementation, the first indication information is indicated by one or more of the following fields in the sub-header of the media access control protocol data unit: logic channel identify (LCID) field, first field.

[0034] Based on this possible implementation, the first indication information can be indicated by the LCID field, or by the first field, or by both the LCID field and the first field, providing three feasible solutions for the implementation of the first indication information.

[0035] Combining the first aspect and the second aspect, in a possible implementation, the first indication information is indicated by the value of the LCID field within the logical channel identification space; wherein, the logical channel identification space is indicated by the first field; or, the first indication information is indicated by an extended LCID field; wherein, the extended LCID field includes the LCID field and the first field.

[0036] Based on this possible implementation, when the first indication information is jointly indicated by the LCID field and the first field, it can be specifically implemented through the above two methods.

[0037] Combining the first aspect and the second aspect, in a possible implementation, the first indication information is further used to indicate the size of the common control channel (CCCH) information; or, the fifth indication information is carried in the first message; wherein, the fifth indication information is used to indicate the size of the CCCH information; the first message is one or more of the following: random access message three, random access message B.

[0038] Based on this possible implementation, the network device can parse the CCCH information according to the size of the CCCH information. In this application, on the one hand, the first indication information can further indicate the size of the CCCH information, and there is no need for additional information to indicate the size of the CCCH information, which can reduce signaling overhead; on the other hand, the terminal device can indicate the size of the CCCH information according to the fifth indication information. The terminal device can, according to the actual communication situation, dynamically and separately indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource and / or the size of the CCCH information, which can improve the flexibility of the terminal device to indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource and the size of the CCCH information.

[0039] Combining the first aspect and the second aspect, in a possible implementation, the first indication information is further used to request uplink transmission enhancement; or, the first request information is carried in the first message; wherein, the first request information is used to request uplink transmission enhancement, and the first message is one or more of the following: random access message three, random access message B.

[0040] Based on this possible implementation, the network device can request uplink transmission enhancement according to the terminal device, and indicate to the terminal device that multiple uplink resources are used to transmit the first information. Compared with scheduling uplink resources multiple times to transmit the first information, the transmission delay can be reduced. In the present application, on the one hand, the first indication information can also request uplink transmission enhancement, and there is no need to request uplink transmission enhancement with additional information, which can reduce signaling overhead; on the other hand, the terminal device can request uplink transmission enhancement according to the first request information. The terminal device can dynamically indicate the terminal device's ability to avoid the second resource when sending the first information on the first resource and / or request uplink transmission enhancement according to the actual communication situation, which can improve the terminal device's ability to instruct the terminal device to avoid the second resource when sending the first information on the first resource and the flexibility of requesting uplink transmission enhancement.

[0041] In a third aspect, a communication method is provided, which can be executed by a terminal device. Unless otherwise specified, the "terminal device" in this application can refer to the terminal device itself, or a component in the terminal device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can implement all or part of the functions of the terminal device. The method includes: the terminal device receives configuration information of a first random access resource; indicating the terminal device's ability to avoid a second resource when sending a first information on the first resource through the first random access resource; wherein the second resource is a resource in the first resource that overlaps with the third resource.

[0042] Based on this scheme, compared with the ability of the terminal device to avoid the second resource when sending the first information on the first resource as displayed by the first indication information, the terminal device can implicitly indicate through the first random access resource that the terminal device can avoid the second resource when sending the first information on the first resource. This allows the network device and the terminal device to coordinate the resources for transmitting the first information, and to avoid the network device from receiving the first information and other information (the other information is the information transmitted on the third resource) on overlapping resources as much as possible, thereby ensuring communication reliability and improving communication performance.

[0043] In a possible implementation, when the terminal device supports avoiding the second resource when sending the first information on the first resource, random access is initiated through the first random access resource.

[0044] Based on this possible implementation, the terminal device can initiate random access through the first random access resource, and can implicitly instruct the terminal device to avoid the second resource when sending the first information on the first resource, thereby providing a feasible solution for the terminal device to instruct the terminal device to avoid the second resource when sending the first information on the first resource.

[0045] In a possible implementation, the terminal device sends first information to the network device on the resources in the first resource other than the second resource; or, receives third indication information from the network device; sends first information to the network device on the resources in the first resource other than the second resource; or, receives third indication information from the network device; sends first information to the network device on the first resource; wherein, the third indication information is used to indicate that the terminal device avoids a third resource when sending the first information; the third indication information is used to indicate that the terminal device does not avoid the third resource when sending the first information.

[0046] Based on this possible implementation, on the one hand, the terminal device can directly send the first information on the resources in the first resource other than the second resource without additional indication information from the network device, which can reduce the transmission overhead. At the same time, it can ensure that when the network device receives the first information, it is not interfered by other information (the other information is the information transmitted on the third resource), which can improve the reliability of communication and thus improve the communication performance. On the other hand, the network device can indicate the resources for the terminal device to send the first information according to the actual communication situation, which can improve the flexibility of determining the resources for sending the first information. The third indication information can indicate that the terminal device avoids the second resource when sending the first information, and the terminal device can send the first information on the resources in the first resource other than the second resource to ensure that the network device is not interfered by other information when receiving the first information, which can improve the reliability of communication and thus improve the communication performance. The third indication information can indicate that the terminal device does not avoid the second resource when sending the first information, which can reduce the operation complexity of the terminal device for sending the first information to improve the working efficiency of the terminal device and is more friendly to the implementation of the terminal device.

[0047] In a possible implementation, the first random access resource is further used to indicate that the terminal device requests uplink transmission enhancement; or, the terminal device sends first request information; wherein, the first request information is used to request uplink transmission enhancement.

[0048] Based on this possible implementation, the network device can, based on the request of the terminal device for uplink transmission enhancement, indicate to the terminal device that multiple uplink resources are used to transmit the first information. Compared with scheduling uplink resources multiple times to transmit the first information, the transmission delay can be reduced. In the present application, on the one hand, the terminal device initiating random access through the first random access resource can implicitly indicate the terminal device to request uplink transmission enhancement, and no additional information is needed to request uplink transmission enhancement, which can reduce signaling overhead; on the other hand, the terminal device can request uplink transmission enhancement based on the first request information. The terminal device can dynamically indicate the terminal device's ability to avoid the second resource when sending the first information on the first resource and / or request uplink transmission enhancement based on the actual communication situation, which can improve the terminal device's ability to instruct the terminal device to avoid the second resource when sending the first information on the first resource and the flexibility of requesting uplink transmission enhancement.

The method includes: the network device sends configuration information of a first random access resource; based on the first random access resource, determining the ability of the terminal device to avoid a second resource when sending a first information on the first resource; wherein the second resource is a resource in the first resource that overlaps with the third resource.

[0050] Based on this scheme, compared with the network device's display of determining the terminal device's ability to avoid the second resource when sending the first information on the first resource through the first indication information, the network device can implicitly determine the terminal device's ability to avoid the second resource when sending the first information on the first resource by receiving a random access message on the first random access resource. The network device can coordinate with the terminal device on the resources for transmitting the first information. The network device can avoid receiving the first information and other information (the other information is the information transmitted on the third resource) on overlapping resources as much as possible, thereby ensuring communication reliability and improving communication performance.

[0051] In a possible implementation, a random access message is received on a first random access resource.

[0052] Based on this possible implementation, the network device can implicitly determine that the terminal device can avoid the second resource when sending the first information on the first resource by receiving a random access message on the first random access resource, thereby providing a feasible solution for determining that the terminal device can avoid the second resource when sending the first information on the first resource.

[0053] In a possible implementation, the network device receives first information from the terminal device only on resources in the first resource other than the second resource; or, sends third indication information to the terminal device and receives first information from the terminal device only on resources in the first resource other than the second resource, where the third indication information is used to instruct the terminal device to avoid the third resource when sending the first information; or, sends third indication information to the terminal device and receives first information from the terminal device on the first resource, where the third indication information is used to instruct the terminal device not to avoid the third resource when sending the first information.

[0054] Based on this possible implementation, on the one hand, the network device can directly receive the first information on resources in the first resource other than the second resource. The network device does not need to additionally indicate other information, which can reduce the transmission overhead. At the same time, it can ensure as much as possible that when the network device receives the first information, it is not interfered by other information (the other information is the information transmitted on the third resource), which can improve the reliability of communication and thus improve the communication performance. On the other hand, the network device can indicate the resources for the terminal device to send the first information according to the actual communication situation, which can improve the flexibility of determining the resources for sending the first information. The third indication information can instruct the terminal device to avoid the second resource when sending the first information, and the terminal device can send the first information on resources in the first resource other than the second resource to ensure as much as possible that the network device is not interfered by other information when receiving the first information, which can improve the reliability of communication and thus improve the communication performance.

The following description of the implementation methods of this application does not constitute a limitation on the scope of protection of this application.

[0115] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the related technologies of the present application is first given as follows.

[0116] 1) Random access (RA)

[0117] When a terminal device communicates with a network device, the terminal device can perform uplink and downlink synchronization with the network device, that is, on the one hand, the terminal device can achieve downlink synchronization based on a reference signal sent by the network device; on the other hand, the terminal device can perform random access to achieve uplink synchronization.

[0118] Among them, the types of random access can be divided into contention-based random access (CBRA) and contention-free random access (CFRA), and the methods of random access can be divided into four-step random access and two-step random access.

[0119] 2) CBRA

[0120] Among them, in CBRA, a terminal device in a cell can select a random access resource from a shared random access resource (or a public random access resource) to initiate a random access; accordingly, the network device can use a contention resolution mechanism to process this type of access request.

[0121] It is understandable that a terminal device may select the same random access resource as another terminal device, so the result of random access is uncertain and not all random accesses will be successful.

[0122] In one possible implementation, the specific process of the four-step random access CBRA can be as follows: Figure 1 As shown:

[0123] S101. The terminal device sends Message 1 (Message1, Msg1) to the network device; correspondingly, the network device receives Msg1 from the terminal device.

[0124] Among them, Msg1 can also be referred to as the first random access message, and Msg1 includes a random access preamble.

[0125] It can be understood that the terminal device can select random access resources and send a random access preamble on a random access channel (RA channel, RACH) occasion (RACH occasions, RO).

[0126] It can be understood that after the terminal device sends the random access preamble, it can start the RA response window (RAresponse window) timer.

[0127] S102. The network device sends Message 2 (Message2, Msg2) to the terminal device; correspondingly, the terminal device receives Msg2 from the network device.

[0128] Among them, Msg2 can also be referred to as the second random access message, and Msg2 includes a random access response (RAR).

[0129] Among them, the RAR may include a random access preamble identifier, timing advance (TA) time adjustment information, uplink grant (UL grant) information, and a temporary cell radio network temporary identifier (TC-RNIT), etc.

[0130] It can be understood that when the terminal device receives the RAR within the RA response window and the random access preamble identifier in the RAR is the same as the identifier of the random access preamble in S101, the response is successful, and the terminal device can send Message 3 (Message3, Msg3) on the uplink resource; or, when the terminal device does not receive the RAR within the RA response window, and / or the random access preamble identifier in the RAR is different from the identifier of the random access preamble in S101, the response fails, and the terminal device can re-execute S101.

[0131] S103. The terminal device sends Msg3 to the network device; correspondingly, the network device receives Msg3 from the terminal device.

[0132] Among them, Msg3 can also be referred to as random access message three.

[0133] Among them, the terminal device can send Msg3 on the uplink resource, and Msg3 includes uplink information.

[0134] Among them, the uplink information can be a radio resource control (RRC) setup request message, an RRC resume request message, or a beam failure recovery (BFR) MAC control element (CE).

[0135] Optionally, the uplink information can also include the identification information of the terminal device.

[0136] It can be understood that the uplink information can be transmitted on the MAC PDU.

[0137] Among them, the MAC PDU can include one or more MAC sub-PDUs (MAC subPDU), one MAC sub-PDU can include a sub-header, and a sub-header can include a logic channel identify (LCID) field and one or more reserved bits.

[0138] Among them, the LCID field is used to indicate or identify the information in the MAC sub-PDU.

[0139] It can be understood that after the terminal device sends Msg3, it can start or restart the RA contention resolution timer.

[0140] S104. The network device sends message 4 (Message4, Msg4) to the terminal device; correspondingly, the terminal device receives Msg4 from the network device.

[0141] Among them, Msg4 can also be referred to as random access message four, and Msg4 includes a contention resolution message.

[0142] Among them, the contention resolution message includes the terminal device contention resolution identifier.

[0143] It can be understood that when the terminal device receives a contention resolution message during the operation of the RA contention resolution timer, and the contention resolution identifier of the terminal device is the same as the identifier information of the terminal device in S103, the terminal device successfully randomly accesses the network device; or, when the terminal device does not receive a contention resolution message during the operation of the RA contention resolution timer, and / or the contention resolution identifier of the terminal device is different from the identifier information of the terminal device in S103, the terminal device can re-execute S101.

[0144] In another possible implementation, the specific process of CBRA for two-step random access can be as follows Figure 2 as shown:

[0145] S201. The terminal device sends Message A (MsgA) to the network device; correspondingly, the network device receives MsgA from the terminal device.

[0146] Among them, MsgA can be referred to as random access message A, and MsgA includes a random access preamble and a physical uplink shared channel (PUSCH) payload.

[0147] Among them, the random access preamble can refer to the random access preamble in the above S101, and the PUSCH payload can include uplink information, and the uplink information can refer to the uplink information in the above S103.

[0148] It can be understood that after the terminal device sends MsgA, it can start or restart the RA contention resolution timer.

[0149] S202. The network device sends Message B (MsgB) to the terminal device; correspondingly, the terminal device receives MsgB from the network device.

[0150] Among them, MsgB can be referred to as random access message B. When the network device receives and decodes the random access preamble and the PUSCH payload, MsgB includes an RAR, and the RAR can include one or more of the following: the contention resolution identifier of the terminal device, TA time adjustment information, or C-RNTI.

[0151] It can be understood that when the terminal device receives an RAR during the operation of the RA contention resolution timer, and the contention resolution identifier of the terminal device is the same as the random access identifier information in S201, the terminal device successfully randomly accesses the network device; when the terminal device does not receive an RAR during the operation of the RA contention resolution timer, and / or the contention resolution identifier of the terminal device is different from the random access identifier information in S201, the terminal device can re-execute S201.

[0152] Among them, when the network device receives and decodes a random access preamble but does not decode the PUSCH payload, MsgB may indicate a fallback RAR, and the fallback RAR may include a preamble identifier, TA timing advance information, uplink resources, and a temporary C-RNTI, etc.

[0153] It can be understood that when the terminal device receives a fallback RAR during the operation of the RA contention resolution timer and the terminal device contention resolution identifier is consistent with the random access identifier information in S201, the two-step random access falls back to a four-step random access, and the terminal device can continue the following steps:

[0154] S203. The terminal device sends Msg3 to the network device; correspondingly, the terminal device receives Msg3 from the network device.

[0155] Among them, Msg3 can refer to Msg3 in the above S103 and will not be elaborated here.

[0156] S204. The network device sends Msg4 to the terminal device; correspondingly, the terminal device receives Msg4 from the network device.

[0157] Among them, Msg4 can refer to Msg4 in the above S104 and will not be elaborated here.

[0158] 3). CFRA

[0159] Among them, in CFRA, the terminal device can initiate random access based on dedicated / standalone random access resources, that is, there is no random access conflict between different terminal devices.

[0160] In a possible implementation, the specific process of CFRA for four-step random access can be as follows Figure 3 as shown:

[0161] S301. The network device sends dedicated random access resource information to the terminal device; correspondingly, the terminal device receives the dedicated random access resource information from the network device.

[0162] S302. The terminal device sends Msg1 to the network device; correspondingly, the terminal device receives Msg1 from the network device.

[0163] Optionally, Msg1 may include a dedicated random access preamble.

[0164] It can be understood that the terminal device can send a dedicated random access preamble on the RO; or, the terminal device can send a random access preamble on a dedicated RO; or, the terminal device sends a dedicated random access preamble on a dedicated RO, without limitation.

[0165] S303. The network device sends Msg2 to the terminal device; correspondingly, the terminal device receives Msg2 from the network device.

[0166] Among them, Msg2 includes RAR, and RAR is used to indicate that the terminal device has successfully randomly accessed the network device.

[0167] In another possible implementation, the specific process of CFRA for two-step random access can be as follows Figure 4 as shown:

[0168] S401. The network device sends dedicated random access resource information and dedicated PUSCH resource information to the terminal device; correspondingly, the terminal device receives the dedicated random access resource information and dedicated PUSCH resource information from the network device.

[0169] S402. The terminal device sends MsgA to the network device; correspondingly, the network device receives MsgA from the terminal device.

[0170] S403. The network device sends MsgB to the terminal device; correspondingly, the terminal device receives MsgB from the network device.

[0171] Based on the above description of the random access process, after Msg4 or MsgB, the terminal device can also be scheduled to continue with uplink transmission (which can be referred to as Message 5 (Msg5) or subsequent uplink transmission), that is, the terminal device can send uplink information (or uplink message) to the network device, and the uplink information can be used for registration, user equipment (UE) identification, UE authentication, security, UE capability reporting, etc.

[0172] 4). Uplink transmission enhancement

[0173] Among them, in the non-terrestrial network (NTN) scenario, the distance between the network device and the terminal device is relatively far, which will cause a large signal transmission loss, and the transmit power of the terminal device is limited, which will result in a limited uplink link budget. Then, the amount of information (such as the number of bits) of an uplink information sent by the terminal device is small, resulting in the need for the terminal device to send multiple uplink information to the network device after randomly accessing the network device to complete link establishment. However, the network device schedules uplink resources (such as PUSCH resources) multiple times to enable the terminal device to send multiple uplink information to the network device on multiple uplink resources, which will cause a large transmission delay.

[0174] It can be understood that in a ground network scenario, similar problems also exist for terminal devices and network devices, that is, the terminal device needs to send multiple uplink messages to the network device (such as a base station) to complete link establishment, and the network device schedules uplink resources multiple times, resulting in a relatively large transmission delay.

[0175] Therefore, the terminal device can request uplink transmission enhancement, that is, the network device can schedule multiple uplink resources at one time according to the request for uplink transmission enhancement (instead of scheduling multiple uplink resources multiple times), and the terminal device can send uplink messages to the network device on multiple uplink resources, thereby reducing the transmission delay.

[0176] In a possible implementation, the network device can indicate a quality threshold to the terminal device and send a reference signal to the terminal device. Correspondingly, the terminal device can determine a measurement result according to the reference signal. When the measurement result is less than or equal to the quality threshold, the terminal device can request uplink transmission enhancement from the network device in Msg3 or MsgA. Further, after determining that the terminal device requests uplink transmission enhancement, the network device can indicate one or more PUSCH resources to the terminal device in Msg4 or MsgB, and the terminal device can send uplink messages on the one or more PUSCH resources; correspondingly, the network device can receive uplink messages from the terminal device on the one or more PUSCH resources, which can avoid the network device scheduling uplink resources multiple times as much as possible, thereby reducing the transmission delay.

[0177] However, the above one or more PUSCH resources may overlap with other resources. For example, they may overlap with random access resources, resulting in the network device possibly receiving an uplink message of one terminal device and a random access message of another terminal device simultaneously on the overlapping resources. If the network device does not have the ability to receive in parallel, it will lead to reception failure and affect the communication performance.

[0178] Therefore, how the terminal device performs uplink transmission to ensure that the network device can achieve uplink reception, thereby ensuring communication reliability and improving communication performance has become a technical problem to be solved urgently.

[0179] To solve the above technical problems, the present application provides a communication method, which includes: the terminal device sends first indication information; and sends first information. The first indication information is used to indicate the ability of the terminal device to avoid a second resource when sending the first information on a first resource; the second resource is a resource in the first resource that overlaps with a third resource.

[0180] In the embodiments of the present application, when the terminal device sends the first indication information to the network device, the network device can determine whether the terminal device supports avoiding the second resource when sending the first information on the first resource, and the network device can coordinate with the terminal device the resources for transmitting the first information according to the first indication information, so as to avoid, as much as possible, the network device receiving the first information and other information (the other information is the information transmitted on the third resource) on the overlapping resources, which can ensure communication reliability and thus improve communication performance.

[0181] The technical solutions of the embodiments of the present application can be applied to various communication systems. The communication system can be a 3rd generation partnership project (3GPP) communication system, for example, a fourth-generation (4G), long term evolution (LTE), fifth-generation (5G) mobile communication system, a new radio (NR) system, or a system with hybrid networking of LTE and 5G, or a non-terrestrial network (NTN) system, or a 6th generation (6G) or other mobile communication systems evolved after 5G, such as a vehicle to everything (V2X) system, or a device-to-device (D2D) communication system, a machine to machine (M2M) communication system, an Internet of Things (IoT), a narrow band-Internet of Things (NB-IoT), other next-generation communication systems, a perception-communication integrated system, a satellite communication system, etc. The communication system can also be a non-3GPP communication system, such as a wireless local area network (WLAN) system like wireless fidelity (Wi-Fi), without limitation.

[0182] Among them, NTN is a general term for networks involving flying objects, including satellite communication networks, high altitude platform stations (HAPS), and air-to-ground networks.

[0183] Exemplarily, the application scenarios of NTN can include areas with poor terrestrial coverage, such as marine communication, public safety requirements, inter-aircraft communication, and railway communication, aiming to provide mobile broadband services for users.

[0184] Among them, the satellite communication network relies on the spaceborne platform, mainly including low earth orbiting (LEO) satellites, medium earth orbiting (MEO) satellites, and geostationary earth orbiting (GEO) satellites; HAPS can be carried on airborne platforms (such as airplanes, balloons, and airships), and HAPS can be used as a mobile communication network device to provide mobile services using the same frequency band as the terrestrial mobile network.

[0185] The technical solutions of the embodiments of the present application can be applied to various communication scenarios. For example, they can be applied to one or more of the following communication scenarios: service scenarios with requirements for low latency and high reliability, enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), machine type communication (MTC), massive machine type communications (mMTC), enhanced machine type communication (eMTC), IoT, narrow band internet of thing (NB-IoT), customer premise equipment (CPE), augmented reality (AR), virtual reality (VR), D2D, V2X, vehicle to vehicle (V2V), etc.

[0198] For example, the network device may include an evolved NodeB (NodeB or eNB or e-NodeB, evolutional Node B) in an LTE system or an enhanced LTE (LTE-advanced, LTE-A) system, such as a traditional macro eNB and a micro eNB in a heterogeneous network scenario. Or, it may include a next generation node B (gNB) in an NR system. Or, it may include a transmission reception point (TRP), a home base station (for example, home evolved NodeB, or home Node B, HNB), a base band unit (BBU), a BBU pool, or a Wi-Fi access point (AP), etc. Or, it may include a base station in NTN, that is, it may be deployed on a flying platform or a satellite. In NTN, the network device may act as a layer 1 (L1) relay, or may act as a base station, or may act as an integrated access and backhual (IAB) node. Or, the network device may be a device that implements the base station function in IoT, such as a device that implements the base station function in drone communication, V2X, D2D, or machine to machine (M2M).

[0199] The network device may also be a module or unit capable of implementing some functions of the base station. For example, the network device may be a CU, a DU, a CU-control plane (CP), a CU-user plane (UP), or an RU, etc. The CU and the DU may be set separately, or may also be included in the same network element, such as in a baseband unit (BBU). The RU may be included in a radio frequency device or a radio frequency unit, such as included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0200] In different systems, the CU (or CU-CP and CU-UP), DU, or RU may also have different names, but those skilled in the art can understand their meanings. For example, the network device may be a network device or a module of a network device in an open radio access network (ORAN) system. In the ORAN system, the CU may also be referred to as an open (O)-CU, the DU may also be referred to as an O-DU, the CU-CP may also be referred to as an O-CU-CP, the CU-UP may also be referred to as an O-CU-UP, and the RU may also be referred to as an O-RU. Any one of the CU (or CU-CP, CU-UP), DU, and RU in this application may be implemented through a software module, a hardware module, or a combination of a software module and a hardware module.

[0201] Optionally, the base station in the embodiments of this application may include various forms of base stations, such as: macro base stations, micro base stations (also known as small stations), relay stations, access points, home base stations, TRPs, transmitting points (TPs), or mobile switching centers, etc. The embodiments of this application do not make specific limitations thereto.

[0202] Among them, Figure 5 the core network device in may include a user plane network element and a mobility management network element.

[0203] Among them, the user plane network element mainly responds to requests from the session management network element and serves as a connection point between the access network device and the data network.

[0204] Among them, the mobility management network element is mainly responsible for tasks such as access authentication of terminal devices, mobility management, and signaling interaction between various functional network elements, such as: managing the registration status of users, the connection status of users, user registration to the network, tracking area update, cell handover user authentication, and key security, etc.

[0205] It can be understood that as shown below Figure 6 the core network device may be connected to one or more network devices. The port between the core network device and the network device is NG. The network device may be a gNB (i.e., a 5G base station) or an ng-eNB (i.e., a 4G base station connected to the 5G core network).

[0206] Among them, the gNB may provide the user plane and control plane protocol functions of 5G NR for terminal devices; the ng-eNB may provide the user plane and control plane protocol functions of 4G E-UTRA for terminal devices.

[0207] Among them, the interface between the core network device and the base station is NG, and the interface between the base stations is Xn.

[0208] Based on the above descriptions of communication systems, network devices, and terminal devices, in one possible implementation, the NTN system can be divided into a transparent payload architecture and a regenerative payload architecture.

[0209] Among them, in the transparent payload architecture, the satellite can forward signals but has no data processing capabilities.

[0210] An example is as follows Figure 7 As shown in (a) below, the base station can be located on the ground. The satellite can be connected to the base station through a ground gateway, and the terminal device is within the coverage area of the satellite. When the terminal device communicates with the base station, the signal can be forwarded through the satellite.

[0211] Among them, the data processing function is still located at the base station. The link between the satellite and the terminal device can be a service link, and the link between the satellite and the base station can be a feeder link.

[0212] Another example is as follows Figure 7 As shown in (b) below, the terminal device is within the coverage area of the satellite. When the base station is located on the satellite, the satellite can have all the data processing functions of the base station; or when the DU is located on the satellite, the satellite can have some of the data processing functions of the base station. The satellite can communicate with the terminal device and perform data processing.

[0213] Among them, the link between the satellite (which can also be called the base station) and the terminal device can be a service link.

[0214] It can be understood that based on the movement of the NTN cell in the ground coverage area, the NTN cell can be divided into earth-fixed, quasi-earth-fixed, and earth-moving.

[0215] Among them, in the earth-fixed type, the coverage area of the NTN cell is fixed to a certain area on the ground, that is, continuous fixed-point coverage. The NTN cell provided by the GEO satellite is of the earth-fixed type.

[0216] Among them, in the quasi-earth-fixed type, the coverage area of the NTN cell is fixed to a certain area on the ground for a period of time and then will be replaced by another area on the ground, that is, fixed-point coverage within a period of time. LEO satellites and MEO satellites can provide NTN cells of the quasi-earth-fixed type.

[0217] An example is as follows Figure 8As shown, as the satellite moves, at time 1 and time 2, the coverage area of the satellite is area 1, and at time 3, the coverage area of the satellite is area 2.

[0218] Among them, in the ground mobile type, the coverage area of the NTN cell slides on the ground. LEO satellites and MEO satellites can provide NTN cells of the ground mobile type

[0219] Exemplarily, as follows Figure 9 As described, as the satellite moves, at time 1, the coverage area of the satellite is area 1; at time 2, the coverage area of the satellite is area 2; at time 3, the coverage area of the satellite is area 3.

[0220] It should be noted that the communication system described in the embodiments of the present application is to more clearly illustrate the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0221] When specifically implemented, Figure 5 As shown, each core network device, network device, and terminal device can adopt Figure 10 the shown composition structure, or include Figure 10 the shown components. Figure 10 This is a schematic diagram of the composition of a communication device 100 provided by an embodiment of the present application. The communication device 100 can be a core network device or a chip or system-on-chip of a core network device, or a component that completes part or all of the functions of a core network device; it can also be a network device or a chip or system-on-chip in a network device, or a component that completes part or all of the functions of a network device; it can also be a terminal device or a chip or system-on-chip in a terminal device, or a component that completes part or all of the functions of a terminal device.

[0222] Such as Figure 10 As shown, the communication device 100 includes one or more processors 1001. Further, the communication device 100 may further include a communication bus 1002 and at least one communication interface ( Figure 10 is only exemplary here. Taking the communication device 100 including a communication interface 1004 and one processor 1001 as an example for illustration). Optionally, the communication device 100 may further include a memory 1003.

[0223] The processor 1001 can be a general-purpose central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the present application solution, or a processing core for processing data (such as computer program instructions). The processor can be a single-CPU processor or a multi-CPU processor.

[0224] In a specific implementation, as an embodiment, the processor 1001 can include one or more CPUs, such as Figure 10 CPU0 and CPU1 in

[0225] The communication bus 1002 can be a Peripheral Component Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus, etc. This bus can be divided into an address bus, a data bus, a control bus, etc. For the sake of representation, Figure 10 only a thick line is used to represent it in

[0226] The communication interface 1004 can be a transceiver module for communicating with other devices or communication networks. Such a communication network can be, for example, Ethernet, a radio access network (RAN), or a wireless local area network (WLAN), etc. Exemplarily, the communication interface 1004 can be a device such as a transceiver or a transceiver. Alternatively, the communication interface 1004 can also be a transceiver circuit located within the processor 1001 to implement the signal input and signal output of the processor.

[0227] The memory 1003 can be a device with storage functions. For example, it can be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions. It can also be an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compact discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory can exist independently and be connected to the processor through the communication bus 1002. The memory can also be integrated with the processor.

[0228] Exemplarily, the memory 1003 is used to store computer execution instructions for implementing the solution of this application, and is controlled by the processor 1001 for execution. The processor 1001 is used to execute the computer execution instructions stored in the memory 1003, so as to implement the method provided in the embodiments of this application.

[0229] Alternatively, optionally, in the embodiments of this application, it can also be that the processor 1001 executes the functions related to processing in the methods provided in the following embodiments of this application, and the communication interface 1004 is responsible for communicating with other devices or communication networks. The embodiments of this application do not make specific limitations in this regard.

[0230] Optionally, the computer execution instructions in the embodiments of this application can also be referred to as application program code. The embodiments of this application do not make specific limitations in this regard.

[0231] In a specific implementation, as an example, the communication device 100 may further include an output device 1005 and an input device 1006. The output device 1005 communicates with the processor 1001 and can display information in various ways. For example, the output device 1005 may be a liquid crystal display (LCD), a light emitting diode (LED) display device, a cathode ray tube (CRT) display device, or a projector, etc. The input device 1006 communicates with the processor 1001 and can receive user input in various ways. For example, the input device 1006 may be a mouse, a keyboard, a touch screen device, or a sensing device, etc.

[0232] It should be noted that Figure 10 the component structure shown in Figure 10 does not constitute a limitation on the communication device. Except for

[0233] the components shown, the communication device may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0234] As follows Figure 11 shown, is an interaction diagram of a communication method provided by the present application. This communication method is described by taking the interaction between a network device and a terminal device as an example. Of course, the entity performing the actions of the network device in this method may also be a device / module in the network device, such as a chip, a processor, a processing unit, etc. in the network device; the entity performing the actions of the terminal device in this method may also be a device / module in the terminal device, such as a chip, a processor, a processing unit, etc. in the terminal device. The present application embodiments do not make specific limitations on this. The steps performed by a single execution entity (for example, a network device or a terminal device) in the present application embodiments may also be divided into being performed by multiple execution entities, and these execution entities may be logically and / or physically separated. Exemplarily, referring to Figure 11 , this communication method includes the following steps:

[0235] S1101. The terminal device sends first indication information to the network device; correspondingly, the network device receives the first indication information from the terminal device.

[0236] Among them, the first indication information is used to indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource.

[0237] Among them, the second resource is the resource in the first resource that overlaps with the third resource.

[0238] Optionally, the resource can be a time-domain resource; or, the resource can be a frequency-domain resource; or, the resource can be a code-domain resource; or, the resource can be a time-frequency domain resource; or, the resource can be a time-frequency-code domain resource, without limitation.

[0239] In the first example, taking the resource as a frequency-domain resource as an example, assuming that the first resource is resource blocks 1 - 10 and the third resource is resource blocks 6 - 15, then the resource in the first resource that overlaps with the third resource can be resource blocks 6 - 10, that is, the second resource can be resource blocks 6 - 10.

[0240] In the second example, taking the resource as a time-domain resource as an example, assuming that the first resource is time slots 1 - 10 and the third resource is time slots 6 - 15, then the resource in the first resource that overlaps with the third resource can be time slots 6 - 10, that is, the second resource can be time slots 6 - 10.

[0241] In the third example, taking the resource as a time-frequency domain resource as an example, assuming that the time domain of the first resource is time slots 1 - 10 and the frequency domain is resource blocks 1 - 10, and the time domain of the third resource is time slots 6 - 15 and the frequency domain is resource blocks 6 - 15, then the time-domain resource in the first resource that overlaps with the third resource in the time domain can be time slots 6 - 10, and the frequency-domain resource that overlaps in the frequency domain is resource blocks 6 - 10, that is, the time domain of the second resource is time slots 6 - 10 and the frequency domain is resource blocks 6 - 10.

[0242] Optionally, the first resource can be one or more PUSCH resources.

[0243] Optionally, the third resource can be a random access resource.

[0244] For example, the third resource can be a shared random access resource (such as the random access resource used in a competitive random access process), or a dedicated / independent random access resource (such as the random access resource used in a non-competitive random access process).

[0245] It can be understood that when the second resource is the resource that overlaps between the PUSCH resource and the random access resource, the network device can receive the first information from the terminal device and the random access messages of other terminal devices on the overlapping resource.

[0246] Among them, the first indication information is used to indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource; or it can be described as that the first indication information is used to indicate whether the terminal device supports sending the first information on the resources in the first resource other than the second resource; or it can be described as that the first indication information is used to indicate whether the terminal device supports avoiding the third resource when sending the first information on the first resource; or it can be described as that the first indication information is used to indicate whether the terminal device supports avoiding the second resource when sending the first information on the first resource.

[0247] Exemplarily, taking the first indication information as one bit, when the bit value is 1, it can indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource; when the bit value is 0, it can indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource. Or, when the bit value is 0, it can indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource; when the bit value is 1, it can indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0248] Optionally, the first indication information may be located in the first message.

[0249] Among them, the first message may be one or more of the following: Random Access Message 3 (i.e., Msg3), Random Access Message B (i.e., MsgB).

[0250] Furthermore, the first indication information may be located in the sub-header of the MAC PDU in the first message, such as the sub-header of the MAC PDU in Msg3, or the sub-header of the MAC PDU in MsgB.

[0251] Among them, the sub-header of the MAC PDU can also be understood as the sub-header of the MAC sub-PDU in the MAC PDU.

[0252] Exemplarily, the sub-header of the MAC PDU can be as follows Figure 12 shown, the sub-header of the MAC PDU may include an LCID field and reserved bits (the reserved bits can be as shown by R in Figure 12 .

[0253] Among them, the LCID field may occupy six bits, and the bits in the LCID field can form an LCID value. For example, when the bit value of the first bit in the LCID field is 1, the bit value of the second bit is 0, the bit value of the third bit is 0, the bit value of the fourth bit is 1, the bit value of the fifth bit is 0, and the bit value of the sixth bit is 0, the LCID value is 100100.

[0254] It can be understood that the LCID field can consist of 64 LCID values, and different LCID values can indicate different information.

[0255] Among them, the reserved bits can be one bit or multiple bits (such as two bits).

[0256] Optionally, the first indication information can be indicated by one or more of the following fields in the sub-header of the MAC PDU: the LCID field, or the first field.

[0257] Among them, the first field can be one or more reserved bits in the sub-header of the MAC PDU.

[0258] It can be understood that when the reserved bits are used, they cannot be called reserved bits (that is, the reserved bits can be called the first field). Correspondingly, the reserved bits can be given corresponding meanings or functions.

[0259] In the first possible design, the first indication information can be indicated by the LCID field. Specifically, the first indication information can be indicated by the LCID value.

[0260] In one example, two LCID values (such as LCID1 and LCID2) can be determined. It can be represented by LCID1 that the terminal device supports avoiding the second resource when sending the first information on the first resource. At the same time, it can be represented by LCID2 that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0261] For example, taking the LCID field as 6 bits, when the LCID value is 111111 (that is, LCID1 is 111111), it can indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource; when the LCID value is 100000 (that is, LCID2 is 100000), it can indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0262] In another example, one LCID value (such as LCID1) can be determined. It can be represented by LCID1 that the terminal device supports avoiding the second resource when sending the first information on the first resource. Correspondingly, when the terminal device does not send LCID1 (such as when the terminal device sends any LCID value other than LCID1), it can be defaulted that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0263] In the second possible design, the first indication information can be indicated by the first field.

[0264] In one example, taking the case where the first field occupies a reserved bit, when the bit value is 1, it may indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource; when the bit value is 0, it may indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource. Or, when the bit value is 0, it may indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource; when the bit value is 1, it may indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0265] In another example, taking the case where the first field occupies two reserved bits, when the bit value is 11, it may indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource; when the bit value is 00, 01, or 10, it may indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource. Or, taking the case where the first field occupies two reserved bits, when the bit value is 00, it may indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource; when the bit value is 11, 01, or 10, it may indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0266] In a third possible design, the first indication information may be indicated by the LCID field and the first field.

[0267] Among them, the first indication information may be as follows Figure 13 As shown, the first indication information may be jointly indicated by the LCID field and the first field.

[0268] Among them, the first field may occupy one bit or multiple bits, without limitation.

[0269] Among them, when the first field occupies one bit, the first indication information may be as shown in (a) in Figure 13 and (b) in Figure 13 When the first field occupies two bits, the first indication information may be as shown in (c) in Figure 13

[0270] In a possible implementation, the first indication information is indicated by the value of the LCID field in the logical channel identification space.

[0271] Among them, the logical channel identification space is indicated by the first field.

[0272] In a possible embodiment, taking the case where the first field occupies a reserved bit, when the bit value of the first field is 1, the first indication information may be indicated by the value of the logical identification field of the first logical channel identification space; when the bit value of the first field is 0, the first indication information may be indicated by the value of the logical field of the second logical identification space.​

[0273] Among them, the first logical channel identification space may be a completely new LCID value table (such as the first LCID value table), and the second logical channel identification space may be an existing LCID value table (such as the second LCID value table).

[0274] Exemplarily, taking the case where LCID1 in the first LCID value table indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource, and LCID1 in the second LCID value table indicates that the size of the CCCH information is 48 bits, then when the bit value of the first field is 1, it can be determined according to the first LCID value table that LCID1 indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource; when the bit value of the first is 0, it can be determined according to the second LCID value table that LCID1 indicates that the size of the CCCH information is 48 bits.

[0275] Based on this possible implementation, a completely new LCID value table can be defined. The new LCID value table can correspond to a new logical channel identification space, which can facilitate other uses and purposes in future communication systems. At the same time, the new LCID value table does not affect the use of the existing LCID value table and can be compatible with existing communication systems and future communication systems.

[0276] In another possible implementation, the first indication information is indicated by an extended LCID field.

[0277] Among them, the extended LCID field includes an LCID field and a first field.

[0278] In a possible embodiment, taking the case where the LCID field occupies six bits and the first field occupies one bit, then the extended LCID field can be 7 bits.

[0279] In one example, two LCID values (such as LCID3 and LCID4) can be determined. It can be indicated by LCID3 that the terminal device supports avoiding the second resource when sending the first information on the first resource. At the same time, it can be indicated by LCID4 that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0280] For example, when the LCID value is 1111111 (i.e., LCID3 is 1111111), it can indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource; when the LCID value is 1100000 (i.e., LCID4 is 1100000), it can indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0281] In another example, an LCID value (such as LCID3) can be determined, and LCID3 can be used to indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource. Correspondingly, when the terminal device does not send LCID3 (such as when the terminal device sends any LCID value other than LCID3), it can be defaulted that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0282] Based on this possible implementation, the first indication information is indicated by an extended LCID field. The extended LCID field can determine more selectable values. For example, the original LCID field occupies six bits and the LCID value can be 64, while the extended LCID field occupies seven bits and the LCID value can be 128, nearly doubling the number of selectable values, which can facilitate other uses and purposes in future communication systems.

[0283] S1102. The terminal device sends the first information to the network device; correspondingly, the network device receives the first information from the terminal device.

[0284] Among them, the network device can determine whether the terminal device supports avoiding the second resource when sending the first information on the first resource according to the first indication information, and then can determine the resource for the terminal device to send the first information. The specific content can be as follows Figures 14 - 16 as shown and will not be elaborated here.

[0285] It can be understood that the first information can be transmitted on the same resource or on different resources. For example, taking the first resource including multiple PUSCH resources as an example, the first information can be transmitted on the multiple PUSCH resources.

[0286] Based on Figure 11 the communication method shown above, the terminal device sending the first indication information to the network device can enable the network device to determine whether the terminal device supports avoiding the second resource when sending the first information on the first resource, can enable the network device to coordinate with the terminal device to transmit the first information according to the first indication information, and can avoid the network device receiving the first information and other information (the other information is the information transmitted on the third resource) on overlapping resources as much as possible, which can ensure communication reliability and then improve communication performance.

[0287] Optionally, the first indication information can also be used to indicate the size of the CCCH information.

[0288] It can be understood that the CCCH information can be carried in the random access message three and the random access message B.

[0289] It can be understood that when a network device receives CCCH information from a terminal device, it can further parse the CCCH information by determining the size of the CCCH information. That is, if the network device cannot determine the size of the CCCH information, the network device cannot parse the CCCH information.

[0290] For example, taking the case where the CCCH information is carried in the random access message three, when the network device cannot determine the size of the CCCH information, the network device cannot parse the random access message three, which may cause the terminal device to fail to randomly access the network device.

[0291] In a possible embodiment, taking the case where the first indication information is indicated by the LCID field as an example, the network device can determine whether the terminal device supports avoiding the second resource when sending the first information on the first resource and the size of the CCCH information through the LCID value.

[0292] Exemplarily, taking the case where there are two LCID values (such as LCID11 and LCID12), and both LCID values indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource as an example, it can be indicated by LCID11 that the terminal device supports avoiding the second resource when sending the first information on the first resource and the size of the CCCH information is 48 bits, and it can be indicated by LCID12 that the terminal device supports avoiding the second resource when sending the first information on the first resource and the size of the CCCH information is 64 bits.

[0293] In another possible embodiment, taking the case where the first indication information is indicated by the first field as an example, the network device can determine whether the terminal device supports avoiding the second resource when sending the first information on the first resource and the size of the CCCH information through the first field.

[0294] Exemplarily, taking the case where the first field occupies two reserved bits as an example, when the bit value is 00, it can indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource and the size of the CCCH information is 48 bits; when the bit value is 01, it can indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource and the size of the CCCH information is 64 bits; when the bit value is 10, it can indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource and the size of the CCCH information is 48 bits; when the bit value is 11, it can indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource and the size of the CCCH information is 64 bits.

[0295] It can be understood that the size of the CCCH information can also be determined according to the fifth indication information. That is, the terminal device sends the fifth indication information to the network device. Correspondingly, the network device can determine the size of the CCCH information according to the fifth indication information.

[0296] Among them, the fifth indication information is used to indicate the size of the CCCH information.

[0297] In one example, taking the fifth indication information as one bit, when the bit value is 0, it can indicate that the size of the CCCH information is 48 bits; when the bit value is 1, it can indicate that the size of the CCCH information is 64 bits. Or, when the bit value is 1, it can indicate that the size of the CCCH information is 48 bits; when the bit value is 0, it can indicate that the size of the CCCH information is 64 bits.

[0298] In another example, the fifth indication information can also be indicated by the LCID field, and the network device can determine the size of the CCCH information according to the LCID value.

[0299] For example, taking the existence of two LCID values (such as LCID5 and LCID6) as an example, it can be indicated by LCID5 that the size of the CCCH information is 48 bits, and it can be indicated by LCID6 that the size of the CCCH information is 64 bits.

[0300] It can be understood that, on the one hand, the first indication information can also indicate the size of the CCCH information, and there is no need for additional information to indicate the size of the CCCH information, which can reduce the signaling overhead; on the other hand, the terminal device can indicate the size of the CCCH information according to the fifth indication information. The terminal device can, according to the actual communication situation, dynamically and separately indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource and / or the size of the CCCH information, which can improve the flexibility of the terminal device to indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource and the size of the CCCH information.

[0301] Based on the above descriptions of the first indication information and the fifth indication information, in a possible embodiment, the first indication information may be determined by a first field, and the fifth indication information may be determined by an LCID field. When the bit value of the first indication information is 1 and the LCID value is LCID5, the network device may determine that the terminal device supports avoiding the second resource when sending the first information on the first resource and the size of the CCCH information is 48 bits; or, when the bit value of the first indication information is 1 and the LCID value is LCID6, the network device may determine that the terminal device supports avoiding the second resource when sending the first information on the first resource and the size of the CCCH information is 64 bits; or, when the bit value of the first indication information is 0 and the LCID value is LCID5, the network device may determine that the terminal device does not support avoiding the second resource when sending the first information on the first resource and the size of the CCCH information is 48 bits; or, when the bit value of the first indication information is 0 and the LCID value is LCID6, the network device may determine that the terminal device does not support avoiding the second resource when sending the first information on the first resource and the size of the CCCH information is 64 bits.

[0302] Optionally, the first indication information may also be used to request uplink transmission enhancement.

[0303] In a possible embodiment, taking the first indication information being indicated by the LCID field as an example, the network device may determine whether the terminal device supports avoiding the second resource when sending the first information on the first resource and the terminal device requests uplink transmission enhancement through the LCID value.

[0304] It can be understood that different from requesting uplink transmission enhancement through the first indication information, the terminal device may send a first request information to the network device. Correspondingly, the network device may determine that the terminal device requests uplink transmission enhancement according to the first request information.

[0305] Wherein, the first request information is used to request uplink transmission enhancement.

[0306] Optionally, the first request information may be located in a radio resource control (RRC) establishment request message.

[0307] It can be understood that the network device can indicate multiple uplink resources to the terminal device for transmitting the first information according to the uplink transmission enhancement requested by the terminal device. Compared with scheduling the uplink resources multiple times to transmit the first information, the transmission delay can be reduced. In this application, on the one hand, the first indication information can also request uplink transmission enhancement, and there is no need for additional information to request uplink transmission enhancement, which can reduce the signaling overhead. On the other hand, the terminal device can request uplink transmission enhancement according to the first request information. The terminal device can, according to the actual communication situation, dynamically indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource and / or request uplink transmission enhancement, which can improve the flexibility of the terminal device to indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource and request uplink transmission enhancement.

[0308] Based on the above descriptions of the first request information and the first indication information, the first request information and the first indication information can be in the same message or in different messages, without limitation.

[0309] It can be understood that the first indication information can indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource, the size of the CCCH information, and the terminal device's request for uplink transmission enhancement. In addition, the first indication information can also indicate other information (that is, the first indication information can indicate other information on the basis of indicating the ability of the terminal device to avoid the second resource when sending the first information on the first resource, or can directly indicate other information, or can indicate other information on the basis of indicating the ability of the terminal device to avoid the second resource when sending the first information on the first resource, the size of the CCCH information, and the terminal device's request for uplink transmission enhancement), without limitation.

[0310] Optionally, before the terminal device sends the first indication information, the network device can send the second indication information to the terminal device; correspondingly, the terminal device can receive the second indication information from the network device.

[0311] Among them, the second indication information is used to indicate that the terminal device is allowed to send the first indication information; or, the second indication information is used to indicate that the network device supports the terminal device to send the first indication information; or, the second indication information is used to indicate the network device's ability to parse the first indication information.

[0312] In the first example, taking the second indication information as one bit, when the bit value is 1, it can indicate that the terminal device is allowed to send the first indication information; when the bit value is 0, it can indicate that the terminal device is not allowed to send the first indication information. Or, when the bit value is 0, it can indicate that the terminal device is allowed to send the first indication information; when the bit value is 1, it can indicate that the terminal device is not allowed to send the first indication information.

[0313] In the second example, taking the second indication information as one bit, when the bit value is 1, it may indicate that the terminal device is allowed to send the first indication information; or, when the bit value is 0, it may indicate that the terminal device is allowed to send the first indication information.

[0314] Based on the second example, when the network device sends the second indication information to the terminal device, the terminal device may send the first indication information to the network device; when the network device does not send the second indication information to the terminal device (that is, the terminal device does not receive the second indication information), the terminal device may not send the first indication information to the network device.

[0315] It can be understood that the second indication information may be carried in broadcast signaling (such as system information).

[0316] It can be understood that the terminal device may determine, according to the second indication information, that the network device can parse the first indication information, and can avoid, as much as possible, the situation where the terminal device sends the first indication information to the network device but the network device does not parse the first indication information, ensuring that the first indication information sent by the terminal device can be parsed by the network device, and can avoid, as much as possible, the situation of communication failure caused by misalignment between the network device and the terminal device, and can improve the efficiency of information interaction between the network device and the terminal device.

[0317] Based on the above content, the present application proposes several possible designs for the terminal device to send the first information to the network device for different scenarios:

[0318] In the first possible design, when the network device can parse the first indication information and the first indication information indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource, the specific steps of communication between the network device and the terminal device may be as follows Figure 14 as shown:

[0319] S1401. The network device sends the second indication information to the terminal device; correspondingly, the terminal device receives the second indication information from the network device.

[0320] Among them, the second indication information may refer to the above description of the second indication information and will not be elaborated here.

[0321] It can be understood that when it is default that the network device supports parsing the first indication information, the network device may not send the second indication information to the terminal device (that is, there is no S1401).

[0322] S1402. The terminal device sends the first indication information to the network device; correspondingly, the network device receives the first indication information from the terminal device.

[0323] Among them, the first indication information indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource.

[0324] Optionally, since the network device can parse the first indication information, after receiving the first indication information, the network device may not need to additionally indicate other information, that is, the network device defaults that the terminal device sends the first information on the resources in the first resource except the second resource (as shown in S1403 below), or, after receiving the first indication information, the network device may send the third indication information to the terminal device to indicate the resource for the terminal device to send the first information (as shown in S1404 - S1407 below). The specific steps are as follows:

[0325] S1403: The terminal device sends the first information to the network device on the resources in the first resource except the second resource; correspondingly, the network device receives the first information from the terminal device on the resources in the first resource except the second resource.

[0326] It can be understood that the terminal device does not send the first information to the network device on the second resource; correspondingly, the network device does not receive the first information from the terminal device on the second resource.

[0327] Based on S1403, the terminal device can directly send the first information on the resources in the first resource except the second resource without the network device additionally indicating other information, which can reduce the transmission overhead. At the same time, it can ensure as much as possible that when the network device receives the first information, it is not interfered by other information (the other information is the information transmitted on the third resource), which can improve the reliability of communication and thus improve the communication performance.

[0328] S1404: The network device sends the third indication information to the terminal device; correspondingly, the terminal device receives the third indication information from the network device.

[0329] Among them, the third indication information may be carried in Msg4 or MsgB.

[0330] Among them, the third indication information is used to indicate that the terminal device avoids the second resource when sending the first information on the first resource (or the third indication information can be used to indicate that the terminal device sends the first information on the resources in the first resource except the second resource).

[0331] S1405: The terminal device sends the first information to the network device on the resources in the first resource except the second resource; correspondingly, the network device receives the first information from the terminal device on the resources in the first resource except the second resource.

[0332] S1406. The network device sends third indication information to the terminal device; correspondingly, the terminal device receives the third indication information from the network device.

[0333] The third indication information is used to indicate that the terminal device does not avoid the second resource when sending the first information on the first resource (or the third indication information can be used to indicate that the terminal device sends the first information on the first resource).

[0334] S1407. The terminal device sends the first information to the network device on the first resource; correspondingly, the network device receives the first information from the terminal device on the first resource.

[0335] Based on the above S1404 - S1407, the network device can indicate the resource for the terminal device to send the first information according to the actual communication situation, which can improve the flexibility of determining the resource for sending the first information. On the one hand, the third indication information can indicate that the terminal device avoids the second resource when sending the first information, and the terminal device can send the first information on the resource other than the second resource in the first resource, so as to ensure that the network device is not interfered by other information (the other information is the information transmitted on the third resource) when receiving the first information as much as possible, which can improve the reliability of communication and thus improve the communication performance; on the other hand, the third indication information can indicate that the terminal device does not avoid the second resource when sending the first information, which can reduce the operation complexity of the terminal device for sending the first information to improve the working efficiency of the terminal device and is more friendly to the implementation of the terminal device.

[0336] Based on the above description of the third indication information in S1404 - S1407, in a possible embodiment, taking the third indication information as one bit, when the bit value is 1, it can indicate that the network device instructs the terminal device to avoid the second resource when sending the first information on the first resource; when the bit value is 0, it can indicate that the network device instructs the terminal device not to avoid the second resource when sending the first information on the first resource. Or, when the bit value is 0, it can indicate that the network device instructs the terminal device to avoid the second resource when sending the first information on the first resource; when the bit value is 1, it can indicate that the network device instructs the terminal device not to avoid the second resource when sending the first information on the first resource.

[0337] In another possible embodiment, taking the third indication information as one bit, when the bit value is 1, it can indicate that the network device instructs the terminal device to avoid the second resource when sending the first information on the first resource; or, when the bit value is 0, it can indicate that the network device instructs the terminal device to avoid the second resource when sending the first information on the first resource.

[0338] Exemplarily, when the network device sends the third indication information to the terminal device, the terminal device may avoid the second resource when sending the first information on the first resource; when the network device does not send the third indication information to the terminal device, the terminal device may not avoid the second resource when sending the first information on the first resource.

[0339] Based on the above possible embodiments, the network device may not need to execute S1406. When the terminal device does not receive the third indication information, the terminal device may directly execute S1407.

[0340] In the second possible design, when the network device can parse the first indication information and the first indication information indicates that the terminal device does not support avoiding the second resource when sending the first information on the first resource, the specific steps for communication between the network device and the terminal device may be as follows Figure 15 as shown:

[0341] S1501. The network device sends the second indication information to the terminal device; correspondingly, the terminal device receives the second indication information from the network device.

[0342] Among them, S1501 may refer to S1401 above and will not be elaborated here.

[0343] S1502. The terminal device sends the first indication information to the network device; correspondingly, the network device receives the first indication information from the terminal device.

[0344] Among them, the first indication information indicates that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0345] Optionally, since the network device can parse the first indication information, after receiving the first indication information, the network device may not need to additionally indicate other information, that is, the network device defaults that the terminal device sends the first information on the first resource (as shown in S1503 specifically), or after receiving the first indication information, the network device may send the fourth indication information to the terminal device to indicate the resource for the terminal device to send the first information (as shown in S1504 and S1505 specifically). The specific steps are as follows:

[0346] S1503. The terminal device sends the first information to the network device on the first resource; correspondingly, the network device receives the first information from the terminal device on the first resource.

[0347] Based on 1503, the terminal device can directly send the first information on the first resource without the network device additionally indicating other information, which can reduce the transmission overhead.

[0348] S1504. The network device sends the fourth indication information to the terminal device; correspondingly, the terminal device receives the fourth indication information from the network device.

[0349] Among them, the fourth indication information is used to indicate the fourth resource.

[0350] Among them, the fourth resource is a resource that does not overlap with the third resource.

[0351] Exemplarily, the fourth resource may be one or more PUSCH resources, but the one or more PUSCH resources do not overlap with the third resource.

[0352] S1505. The terminal device sends the first information to the network device on the fourth resource; correspondingly, the network device receives the first information from the terminal device on the fourth resource.

[0353] Based on S1504 and S1505, the terminal device can send the first information on the fourth resource, which can ensure that the network device is less likely to be interfered by other information (the other information is the information transmitted on the third resource) when receiving the first information on the fourth resource, improve the reliability of communication, and thus improve the communication performance.

[0354] For the third possible design, when the network device does not parse the first indication information, the specific steps of communication between the network device and the terminal device can be as follows Figure 16 as shown:

[0355] S1601. The terminal device sends the first indication information to the network device; correspondingly, the network device receives the first indication information from the terminal device.

[0356] It can be understood that the first indication information can indicate that the terminal device supports avoiding the second resource when sending the first information on the first resource, or the first indication information can indicate that the terminal device does not support avoiding the second resource when sending the first information on the first resource.

[0357] S1602. The terminal device sends the first information to the network device on the first resource; correspondingly, the network device receives the first information from the terminal device on the first resource.

[0358] It can be understood that when the network device does not support parsing the first indication information, the network device defaults that the terminal device does not support avoiding the second resource when sending the first information on the first resource, does not send the third indication information or the fourth indication information to the terminal device, and at the same time, the network device receives the first information on the first resource; correspondingly, when the terminal device does not receive the third indication information or the fourth indication information within a preset time period (or, the terminal device does not receive the third indication information or the fourth indication information in a specific message (such as Msg4 or MsgB)), the terminal device can send the first information to the network device on the first resource to align the terminal device and the network device.

[0359] Among them, the preset time period can be predefined, or the preset time period can be configured by the network device, or the preset time period can be defined by the protocol.

[0360] Exemplarily, taking the moment when the terminal device sends the first indication information as moment 1 as an example, assuming the time interval is T, then the preset time period can be moment 1 + T, that is, when the terminal device does not receive the third indication information or the fourth indication information within moment 1 + T, the terminal device can send the first information to the network device on the first resource.

[0361] Based on the above three possible designs, when the terminal device determines that the network device can parse the first indication information (such as the network device sends the second indication information or by default the network device can parse the first indication information), the terminal device can determine the resource for sending the first information without the indication of the network device (for example, when the first indication information indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource, the terminal device can determine the resource for sending the first information according to the third indication information, or can directly send the first information on the resource other than the second resource in the first resource).

[0362] Or, when the terminal device is not sure whether the network device can parse the first indication information (such as the network device does not send the second indication information), the terminal device needs to determine the resource of the first information under the indication of the network device (for example, when the first indication information indicates that the terminal device supports avoiding the second resource when sending the first information on the first resource, the terminal device needs to determine the resource for sending the first information according to the third indication information. If the terminal device does not receive the third indication information, the terminal device will send the first information on the first resource).

[0363] Optionally, different from the ability of the terminal device to explicitly indicate to avoid the second resource when sending the first information on the first resource according to the first indication information, the present application also proposes a communication method. The terminal device can initiate random access based on the first random access resource, and thus implicitly indicate to the network device that the terminal device supports avoiding the second resource when sending the first information on the first resource. The specific steps can be as follows Figure 17 as shown below:

[0364] S1701. The terminal device receives the configuration information of the first random access resource from the network device.

[0365] Among them, the first random access resource can be a specific random access resource.

[0366] Optionally, the first random access resource can include one or more of the following: a specific random access preamble, or a specific RO.

[0367] In the first possible embodiment, taking the first random access resource including a specific random access preamble as an example, the terminal device can send Msg1 on the RO to the network device, and Msg1 can include the specific random access preamble.

[0368] In the second possible embodiment, taking the first random access resource including a specific RO as an example, the terminal device can send Msg1 to the network device on the specific RO, and Msg1 is the same as Msg1 in S101 above.

[0369] In the third possible embodiment, taking the first random access resource including a specific random access preamble and a specific RO as an example, the terminal device can send Msg1 to the network device on the specific RO, and Msg1 can include the specific random access preamble.

[0370] It can be understood that the terminal device can indicate the ability of the terminal device to avoid the second resource when sending the first information on the first resource through the first random access resource.

[0371] Among them, the second resource is the resource in the first resource that overlaps with the third resource.

[0372] S1702. When the terminal device supports avoiding the second resource when sending the first information on the first resource, the terminal device sends a random access message to the network device through the first random access resource; correspondingly, the network device receives the random access message from the terminal device on the first random access resource.

[0373] Among them, the random access message can be Msg1 or MsgA, without limitation.

[0374] In a possible implementation, after the terminal device initiates random access on the first random access resource, the terminal device can directly send the first information to the network device on the resources in the first resource other than the second resource without the indication of the network device.

[0375] In another possible implementation, after the terminal device initiates random access on the first random access resource, the network device can send the third indication information to the terminal device. Further, the terminal device can determine the resource for sending the first information according to the third indication information.

[0376] In an example, when the third indication information indicates that the terminal device should avoid the second resource when sending the first information on the first resource, the terminal device can send the first information to the network device on the resources in the first resource other than the second resource; correspondingly, the network device can receive the first information from the terminal device on the resources in the first resource other than the second resource. Or, when the third indication information indicates that the terminal device does not need to avoid the second resource when sending the first information on the first resource, the terminal device can send the first information to the network device on the first resource; correspondingly, the network device can receive the first information from the terminal device on the first resource.

[0377] In another example, when the network device sends the third indication information to the terminal device, the terminal device can send the first information to the network device on the resources in the first resource other than the second resource; correspondingly, the network device can receive the first information from the terminal device on the resources in the first resource other than the second resource. Or, when the network device does not send the third indication information to the terminal device, the terminal device can send the first information to the network device on the first resource; correspondingly, the network device can receive the first information from the terminal device on the first resource.

[0378] It can be understood that the third indication information can refer to the description of the third indication information above, which will not be elaborated here. Figure 14 and will not be elaborated here.

[0379] Based on the above two possible implementations, reference can be specifically made to the relevant descriptions above, which will not be elaborated here. Figure 14 and will not be elaborated here.

[0380] Optionally, when the network device receives a random access message from the terminal device on the first random access resource, the network device can also determine that the terminal device requests uplink transmission enhancement; or, the terminal device can send the first request information to the network device to request uplink transmission enhancement through the first request information.

[0381] Among them, the first request information can refer to the description of the first request information above, which will not be elaborated here.

[0382] It can be understood that when the terminal device does not support avoiding the second resource when sending the first information on the first resource, the terminal device can send a random access message to the network device through the second random access resource; correspondingly, the network device can receive the random access message from the terminal device on the second random access resource.

[0383] Among them, the second random access resource can be a shared random access resource (such as the random access resource used in a contention-based random access process), or the second random access resource can be a dedicated / independent random access resource (such as the random access resource used in a non-contention-based random access process).

[0384] In a possible implementation, after the terminal device initiates random access on the second random access resource, the terminal device can directly send the first information to the network device on the first resource without the indication of the network device.

[0385] In another possible implementation, after the terminal device initiates random access on the second random access resource, the network device can send the fourth indication information to the terminal device, and the fourth indication information is used to indicate the fourth resource; further, the terminal device can determine that the resource for sending the first information is the fourth resource according to the fourth indication information, and send the first information to the network device on the fourth resource.

[0386] Among them, the fourth indication information can refer to the description of the fourth indication information in S1504 above, and will not be elaborated here.

[0387] Based on the above two possible implementations, specific reference can be made to the relevant descriptions above Figure 15 and will not be elaborated here.

[0388] Based on Figure 17 the communication method shown, compared with the ability of the terminal device to indicate that the terminal device avoids the second resource when sending the first information through the first indication information, the terminal device can implicitly indicate that the terminal device can avoid the second resource when sending the first information through the first random access resource. Further, the terminal device can avoid the second resource when sending the first information to ensure that the network device is not interfered by other information (the other information is the information transmitted on the third resource) when receiving the first information, which can improve the reliability of communication and then improve the communication performance.

[0394] In one implementation scenario, taking the communication device as the terminal device in the above method embodiments as an example, Figure 18 A schematic structural diagram of a terminal device 180 is shown. Among them, the terminal device 180 includes a processing module 1801 and a transceiver module 1802.

[0395] In some embodiments, the terminal device 180 may further include a storage module ( Figure 18 not shown in the figure), which is used to store program instructions and data.

[0396] In some embodiments, the transceiver module 1802, which may also be referred to as a transceiver unit, is used to implement the sending and / or receiving functions. The transceiver module 1802 may be composed of a transceiver circuit, a transceiver, a transceiver, or a communication interface.

[0399] In a possible implementation, the transceiver module 1802 is further used to receive second indication information; wherein, the second indication information is used to indicate that the terminal device is allowed to send the first indication information.
