Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the present application are also applicable to similar technical problems.

To facilitate understanding of the embodiments of the present application, related concepts are introduced below.

In an optional implementation manner, the first resource or the second resource may be a time unit, a frequency domain resource, a time-frequency resource block, or a code domain resource for sending a channel, a signal, or information. Wherein, the time unit may include a frame, a subframe, a time slot, a symbol or a mini-slot, and the like. Optionally, the first resources may also be called initial transmission resources, and correspondingly, the second resources may be called retransmission resources. Correspondingly, the configuration information of the first resource and the configuration information of the second resource may be respectively referred to as initial transmission resource configuration information and retransmission resource configuration information of the first information, which are not limited in this embodiment of the present application. Optionally, the second resource may carry part or all of the first information. For example, when the network device cannot correctly obtain the part of the first information, the terminal device may retransmit the part of the first information.

In an optional implementation manner, the first resource is any one of the following resources: resources used to send a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), or resources used to send a random access preamble (Preamble) code and PUSCH; correspondingly, the second resource is any one of the following resources: resources used to send PUSCH, or resources used to send Preamble codes and PUSCH. Optionally, the first information may be the data transmitted by the PUSCH, or may be the Preamble code and the data transmitted by the PUSCH. The first information may be MsgA in a random access process. The first resource is the resource for transmitting MsgA.

In an optional implementation manner, the initial transmission resources and retransmission resources may include resources bearing other channels: Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH), Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH), Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH), Physical Random Access Channel (Physical Random Access Channel, PRACH), etc., which are not limited in this embodiment .

Optionally, the time-frequency domain resources used by the first resource and the second resource do not overlap, which is beneficial to avoid confusion between initial transmission resources and retransmission resources. Optionally, the time-frequency domain resources used by the first resource and the second resource overlap, and can be distinguished by different predefined pilot ports. Optionally, the configuration information of the first resource and the second resource may be partly the same or completely different, which is not limited in this embodiment of the application.

In the embodiment of the present application, the first information may include a random access preamble code; optionally, the first information may also include the identification of the terminal device carried in the initial access random process and connection establishment information; or, if it is the RRC reestablishment process, the first information may also include the identification of the terminal device in the connected state and connection establishment information, etc. In the embodiment of the present application, the latter two types of information are collectively referred to as PUSCH transmission information, that is, these two types of information may be information carried by resources used to send PUSCH. Optionally, the correspondence between the first resource and the second resource may also be referred to as the correspondence between the initial transmission resource and the retransmission resource of the first information.

In the embodiment of the present application, the configuration information of the first resource may include at least one of the following information: time domain information, frequency domain information, pilot port information, code domain information, beam information, and synchronization signal and broadcast channel block (synchronization signal/Physical Broadcast Channel block, SSB) information, etc.; similarly, the configuration information of the second resource may include at least one of the following information: time domain information, frequency domain information, pilot port information, code domain information, beam information, and SSB information. wait. Optionally, the configuration information of the first resource and the configuration information of the second resource may further include information such as modulation and coding schemes and power. Optionally, the configuration information of the first resource and the configuration information of the second resource may adopt a semi-static configuration ConfiguredgrantConfig, or a compressed ConfiguredgrantConfig configuration method to configure complete resource information. It can be seen that the configuration information of the above-mentioned first resource and the configuration information of the second resource may be complete or incomplete resource information. The more complete resource information is beneficial to the network device to detect the first information from the first resource and the second resource faster; the less resource information is conducive to saving signaling overhead.

Wherein, the time domain information includes information such as an index number of a time unit in the time domain; the frequency domain information includes frequency information of a certain bandwidth in the frequency domain; the pilot port information includes information about the antenna port corresponding to the pilot symbol, wherein the pilot symbol carries a pilot signal; the code domain information includes information about code domain resources in a code division multiple access communication system.

For example, the configuration information of the first resource may be complete resource information, and the configuration information of the second resource may only configure time-frequency domain information. In this way, it is beneficial to reduce signaling overhead. For example, the first resource configuration information adopts ConfiguredgrantConfig, or compressed ConfiguredgrantConfig and other configuration methods to configure complete resource information; the second resource configuration information only includes time-frequency domain information: timeDomainOffset(), timeDomainAllocation(), frequencyDomainAllocation().

Second resource configuration information {

timeDomainOffse();

timeDomainAllocation();

frequencyDomainAllocation();

}.

For another example, both the configuration information of the first resource and the configuration information of the second resource are complete resource information, which can greatly increase the probability that the first information is correctly received during retransmission.

In an optional implementation manner, the corresponding relationship between the first resource and the second resource can be configured through high-level signaling, or configured by broadcast, or predefined. Optionally, the high-layer signaling may be notified by radio resource control (Radio Resource Control, RRC) signaling. For example, the network device sends a first message, and the terminal device receives the first message. The first message is an RRC message. The first message carries a list, and the list stores a correspondence relationship between a first resource and a second resource.

In the embodiment of the present application, the corresponding relationship between the first resource and the second resource may be indicated by any one or more of various optional implementation manners.

In an optional implementation manner, the configuration information of the first resource includes the index number of the second resource, so that it can be learned that there is a correspondence between the first resource and the second resource. Wherein, the second resource index number is a resource index number of the configuration information of the second resource. The second resource index number may also be called the index number of the configuration information of the second resource, the index number of the second resource, or the identifier of the second resource, etc., and is used to distinguish the identifier of the second resource, which is not limited in this embodiment of the present application. As shown in the following structure, Resource 2 represents the second resource index number, and the corresponding resource field is added to the configuration information of the first resource. The resource index number corresponding to the corresponding resource field is Resource 2, indicating that the first resource has a corresponding relationship with the second resource.

Configuration information of the first resource {

…

resource 2;

…

}.

In another optional implementation manner, the configuration information of the second resource includes the index number of the first resource. Wherein, the first resource index number is a resource index number of configuration information of the first resource. The first resource index number may also be called the index number of the configuration information of the first resource, the index number of the first resource, or the identifier of the first resource, etc., and is used to distinguish the identifier of the first resource, which is not limited in this embodiment of the present application. For example, as shown in the structure below, Resource 1 represents the first resource index number, and the corresponding resource field is added to the configuration information of the second resource. The resource index number corresponding to the corresponding resource field is the Resource 1, indicating that the first resource has a corresponding relationship with the second resource.

Configuration information of the second resource {

…

resource 1;

…

}.

In yet another optional implementation manner, the configuration information of the first resource may be placed as a field in the configuration information of the second resource, or the configuration information of the second resource may be placed as a field in the configuration information of the first resource.

In yet another optional implementation manner, the correspondence between the first resource and the second resource may be indicated by correspondence configuration information. The correspondence configuration information is information associating configurations of the first resource and the second resource. As shown in the following structure, the correspondence configuration information includes the association between resource 1 and resource 2.

The corresponding relationship configuration information {

(resource 1; resource 2);

…

}.

In yet another optional implementation manner, the corresponding relationship between the first resource and the second resource may also be indicated by using the above two or more implementation manners. As shown in the following two structures, the configuration information of the first resource includes the second resource index number resource 2, and meanwhile, the configuration information of the second resource includes the first resource index number resource 1.

Configuration information of the first resource {

resource 2;

...;

}

Configuration information of the second resource {

resource 1;

…

}.

In yet another optional implementation manner, the configuration information of the first resource and the configuration information of the second resource each include a first identifier; the first identifier is used to indicate that there is a correspondence between the first resource and the second resource.

In yet another optional implementation manner, the configuration information of the first resource and the configuration information of the second resource each include a first identifier. When the first identifier is a first value, it indicates that the resource is used for initial transmission; when the first identifier is a second value, it indicates that the resource is used for retransmission. For example, the first identifier is 1 bit, and both the configuration information of the first resource and the configuration information of the second resource include the first identifier. When the configuration information of the first resource has a value of 1, it indicates that the first resource is used for initial transmission; when in the configuration information of the second resource, the value of the first identifier is 0, indicating that the second resource is used for retransmission, and corresponds to the first resource that also includes the first identifier in the configuration information.

In the embodiment of the present application, the correspondence between the first resource and the second resource is a one-to-one correspondence or a many-to-one correspondence. In the case of many-to-one correspondence, the initial transmission resource of the first information may not only be the first resource identified by the first resource index number, but may also be resources identified by other resource index numbers. There is a one-to-one correspondence between the first resource and the second resource, and a unique first resource can be found based on the second resource, thereby facilitating obtaining a combination gain of part or all of the first information. Multiple first resources correspond to one second resource, so that when part or all of the first information carried by the multiple first resources is retransmitted, the second resource can be used, which is beneficial to reduce the overhead of retransmission resources.

For example, the corresponding relationship is indicated by the corresponding relationship configuration information, and the resource index numbers of multiple first resources are resource 1, resource 3, and resource 4 respectively. In this way, the structure of the corresponding relationship configuration information can be as follows:

The corresponding relationship configuration information {

(resource 1, resource 3, resource 4; resource 2);

…

}.

In this way, when the first information carried on resource 1 and resource 3 are all received correctly, only resource 4 is not received correctly, then part or all of the retransmitted first information corresponding to resource 4 can be detected on resource 2, which facilitates combined reception of signals on resource 2.

In the embodiment of the present application, in addition to the above-mentioned correspondence between the first resource index number and the second resource index number, the correspondence between the first resource and the second resource may also be determined by using the correspondence between the resource used to send the Preamble code in the first resource and the resource used to send the Preamble code in the second resource. That is to say, only the corresponding relationship between the resources used to send the Preamble code is configured, and the network device and the terminal device can identify the corresponding relationship between the resources used to send the PUSCH twice in the first resource and the second resource based on the corresponding relationship. In this way, it is beneficial to make the resources for sending the PUSCH unnecessary to be predefined, that is, to reduce the resources reserved for sending the PUSCH. Optionally, in the implementation manners represented by the above various correspondence relationships, the first resource index number may be replaced by the initial transmission resource index number of the Preamble code, and the second resource index number may be replaced by the retransmission resource index number of the Preamble code.

Optionally, in this implementation manner, independent Preamble resource pools may be configured for the initially transmitted Preamble code and the retransmitted Preamble code. The resource of the Preamble code may be any one or a combination of time/frequency/code resources. The first N preamble codes (N is a positive integer, such as N=50, N can be a network configuration or protocol agreement) resources on an R0 resource are used for initial transmission, and the preamble codes after N+1 (N=50, that is, 51-64 preamble codes) resources are used for retransmission. Among them, there is a corresponding relationship between the resources of the first N preamble codes and the resources of the preamble codes after N+1, and the correspondence between the resources of the first transmitted preamble codes and the resources of the retransmitted preamble codes can be one-to-one, or many-to-one. Optionally, in the case of many-to-one, every X resources for initial transmission of Preamble codes corresponds to one resource for retransmission of Preamble codes, and X depends on the value of N. For example, assuming that there are 64 preamble code resources in total, N=48, then there are 48 initial preamble code resources and 16 retransmission preamble code resources, then every 3 initial preamble code resources correspond to a retransmission preamble code resource, that is, the initial preamble code resource {1-3} corresponds to the retransmission preamble code resource {49}, and the initial preamble code resource {4-6} corresponds to the retransmission preamble code resource {4-6} The resource {50} of the amble code, ... and so on. When the network side judges the initial transmission or retransmission according to the resource of the received Preamble code, if it is a retransmission, based on the corresponding relationship, the corresponding initial transmission is found, which is conducive to combined reception. Wherein, the R0 resource may be a resource used to bear a random access opportunity, for example, a part of time-frequency resource blocks used to send a Preamble code, and the like.

Optionally, in this embodiment, a Preamble code resource pair may be configured for the resource of the initial preamble code and the resource of the retransmission preamble code, and based on the preamble code resource pair, determine the corresponding relationship between the resource of the initial preamble code and the resource of the retransmission preamble code, and then obtain the PUSCH resource associated with the two transmissions of the preamble code, thereby facilitating combined reception of data carried by the PUSCH resource.

In another optional implementation manner, the corresponding relationship between the first resource and the second resource is through the corresponding relationship between resources used for sending PUSCH in the first resource and resources used for sending PUSCH in the second resource. That is to say, only the corresponding relationship between the initial transmission resource for sending the PUSCH and the retransmission resource for sending the PUSCH is configured, and further, the corresponding relationship between the first resource and the second resource is identified through the corresponding relationship. In this way, it is beneficial to reduce the resources reserved for sending the Preamble code. Optionally, in the implementation manners represented by the above-mentioned various correspondence relationships, the first resource index number may be replaced by an initial transmission resource index number used for sending PUSCH, and the second resource index number may be replaced by a retransmission resource index number used for sending PUSCH.

In yet another optional implementation manner, the correspondence between the first resource and the second resource is indicated by the correspondence between the resource used to send the Preamble code and the resource used to send the PUSCH in the first resource, and the resource used to send the Preamble code in the second resource and the resource used for the PUSCH. That is to say, both the initial transmission resource and the retransmission resource include the resource for sending the Preamble code and the resource for the PUSCH, and correspondingly, the corresponding relationship also includes the corresponding relationship between the two resources. Optionally, in the implementation manners represented by the above-mentioned various correspondence relationships, the first resource index number may be replaced by the initial transmission resource index number of the Preamble code and the initial transmission resource index number used for sending PUSCH, and the second resource index number may be replaced by the retransmission resource index number of the Preamble code and the retransmission resource index number used for sending PUSCH. For example, use the correspondence configuration information to indicate the correspondence between the first resource and the second resource, use Preambleresource 1 to represent the initial transmission resource index number of the Preamble code, Preamble resource 2 represents the retransmission resource index number of the Preamble code, PUSCH resource 1 represents the initial transmission resource index number for sending PUSCH, and PUSCHresource 2 represents the retransmission resource index number for sending PUSCH, then the correspondence configuration information can be expressed as:

The correspondence configuration information {

(Preamble resource 1; Preamble resource 2);

(PUSCH resource 1; PUSCH resource 2);

…

}.

In the embodiment of the present application, the preset time unit is a period of time after the first information is sent, and the timing starting point of the preset time unit may be later than the time when the first information on the first resource is received. For example, the preset time unit may be X symbols/time slot/milliseconds later than the time when the first information is received on the first resource.

Based on the above concept, the following will continue to elaborate on the relevant content of the embodiment of the present application in conjunction with the accompanying drawings. .

Please refer to FIG. 2. FIG. 2 is a schematic flow diagram of an information transmission method provided in an embodiment of the present application. As shown in FIG. 2, the information transmission method is described from the perspective of interaction between a terminal device and a network device, and may include the following steps:

In part 201, the terminal device sends the first information on the first resource, and the network device receives the first information on the first resource;

In part 202, when the terminal device does not receive the response message of the first information within the preset time unit, send part or all of the first information on the second resource corresponding to the first resource; the network device receives part or all of the first information sent by the terminal device on the second resource.

For example, before step 201, the network device sends a first message to the terminal device, where the first message carries the correspondence between the first resource and the second resource. Correspondingly, in part 201, when the network device receives the first information, it can detect the first information, if the detection is successful, it will send the response message of the first information, if the detection fails, it will not send the response message of the first information.

Further, in part 202, after receiving part or all of the first information sent by the terminal device on the second resource, the network device may query the first resource corresponding to the second resource according to the correspondence relationship, that is, the received signal on the initial transmission resource, so as to combine the two received signals to achieve a combination gain for part or all of the first information.

It can be seen that, in this embodiment of the present application, the terminal device sends the first information on the first resource, and when the response message of the first information is not received within the preset time unit, part or all of the first information is sent again on the second resource corresponding to the first resource. Since the two transmissions are respectively transmitted on the first resource and the second resource that have a corresponding relationship, it is beneficial for the network device to combine the first information received twice on the first resource and the second resource. That is to say, in this embodiment of the present application, even if the network device cannot correctly demodulate the first information carried by the first resource, it can also obtain the combination gain between part or all of the first information carried by the second resource and the first information carried by the first resource.

In a possible example, the corresponding relationship between the first resource and the second resource is configured through high-level signaling, or broadcast configuration, or predefined.

In a possible example, the first resource is any one of the following resources: a resource used for sending a physical downlink shared channel PUSCH; or a resource used for sending a preamble code and a PUSCH. For example, the first resource may be a resource used to send MsgA in a random access process.

The second resource is any one of the following resources: resources used for sending PUSCH, or resources used for sending Preamble code and PUSCH. For example, the second resource may be a resource for resending part or all of the information in the MsgA. There may be a corresponding relationship between the second resource and the first resource, and the terminal device may acquire the location of the second resource according to the location of the first resource.

In a possible example, the configuration information of the first resource includes at least one of the following information:

Time domain information, frequency domain information, pilot port information, code domain information, beam information, and, synchronization signal and broadcast channel block SSB information;

The configuration information of the second resource includes at least one of the following information:

Time domain information, frequency domain information, pilot port information, code domain information, beam information, and SSB information.

In a possible example, the corresponding relationship between the first resource and the second resource is indicated by at least one of the following information:

The configuration information of the first resource includes the second resource index number, and the configuration information of the second resource includes the first resource index number, or corresponding relationship configuration information;

Wherein, the second resource index number is the resource index number of the configuration information of the second resource; the first resource index number is the resource index number of the configuration information of the first resource; and the correspondence configuration information is information associating the configuration information of the first resource and the second resource.

In a possible example, the configuration information of the first resource and the configuration information of the second resource respectively include a first identifier;

The first identifier is used to indicate that there is a corresponding relationship between the first resource and the second resource.

In a possible example, the correspondence between the first resource and the second resource is determined by any of the following correspondences:

Correspondence between resources used to send the Preamble code in the first resource and resources used to send the Preamble code in the second resource;

A correspondence between resources used to send PUSCH in the first resource and resources used to send PUSCH in the second resource;

A correspondence relationship between the resource used for sending the Preamble code and the resource used for sending the PUSCH in the first resource, and the resource used for sending the Preamble code and the resource used for the PUSCH in the second resource.

In a possible example, the correspondence between the first resource and the second resource is a one-to-one correspondence or a many-to-one correspondence.

Wherein, for the above possible examples, reference may be made to the detailed elaboration of related concepts, which will not be described in detail here.

The following is a further description in conjunction with a specific scenario example. The first information is MsgA in the random access process as an example. Correspondingly, when the network device correctly receives the MsgA, it may send scheduling information to the terminal device as a response message to the first information, so that the terminal device uses the scheduling information to send information such as the identification of the terminal device and connection establishment. Specifically, as shown in Figure 3, the information transmission method may include the following steps:

In part 301, the network device broadcasts a first message, where the first message carries resource configuration information of a resource sending MsgA.

Wherein, the resource configuration information includes a correspondence configuration information field, and in the correspondence configuration information field, the correspondence configuration information indicates the correspondence between the initial transmission resource of the initial transmission MsgA and the retransmission resource of the retransmission MsgA.

In part 302, the terminal device sends MsgA on the initial transmission resource according to the resource configuration information;

In part 303, the network device receives MsgA on the initial transmission resource, and detects MsgA; when MsgA is successfully detected, executes part 304a, and returns scheduling information; when MsgA fails to detect, does not send scheduling information, and the terminal device executes part 304b;

The MsgA detection failure may be that the network device cannot correctly demodulate the MsgA, or the signal received on the initial transmission resource is too weak due to severe channel fading, etc., which are not limited by the embodiment of the present invention.

In part 304b, when the terminal device does not receive the scheduling information within the preset time unit, it retransmits MsgA or part of the information in MsgA on the retransmission resource corresponding to the initial transmission resource. In a specific example, part of the information in the resent MsgA may include a part that has not been correctly demodulated by the network device.

In part 305, the network device receives MsgA or part of the information in MsgA on the retransmission resource, and queries the initial transmission resource corresponding to the retransmission resource, and demodulates MsgA by using the MsgA sent on the initial transmission resource and the MsgA or part of the information in MsgA sent on the retransmission resource.

Optionally, when the network device receives the MsgA, it can determine whether the resource for transmitting the MsgA is an initial transmission resource or a retransmission resource. If it is a retransmission resource, it can query the initial transmission resource corresponding to the retransmission resource, so as to realize part or all of the combined gain of the MsgA.

It can be seen that in this embodiment of the present application, the terminal device sends MsgA on the initial transmission resource, and sends MsgA again on the retransmission resource when no scheduling information is received within the preset time unit. It can be seen that in the embodiment of the present application, the terminal device may have resources to send MsgA again without receiving the scheduling information, so that even when the network device cannot identify the terminal device and cannot send the scheduling information, part or all of the combined gain of Msg A can be obtained.

Since the steps performed by the terminal device have been described in detail in the foregoing method embodiments, details are not repeated here, and the processing of the first information by the terminal device may refer to the description in the foregoing method embodiments.
