In order to facilitate understanding of the embodiments of the present application, related concepts are described below.

In an alternative embodiment, 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 that transmits a channel, a signal, or information. The time units may include frames, subframes, slots, symbols, or minislots, among others. Alternatively, the first resource may be referred to as a primary resource, and the second resource may be referred to as a retransmission resource. Accordingly, the configuration information of the first resource and the configuration information of the second resource may be referred to as primary transmission resource configuration information and retransmission resource configuration information of the first information, which are not limited in the embodiment of the present application. Alternatively, the second resource may carry part or all of the first information, for example, when the network device cannot obtain the part of the first information correctly, the terminal device may retransmit the part of the first information.

In an alternative embodiment, the first resource is any one of the following resources: resources for transmitting a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) or resources for transmitting a random access Preamble (Preamble) code and PUSCH; accordingly, the second resource is any one of the following resources: resources for transmitting PUSCH, or resources for transmitting Preamble code and PUSCH. Optionally, the first information may be data transmitted by PUSCH, or may be data transmitted by Preamble code and PUSCH. The first information may be MsgA in a random access procedure. The first resource is the resource for transmitting the MsgA.

In an alternative embodiment, the primary transmission resource and the retransmission resource may include resources for carrying 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), and the like, the embodiments of the present application are not limited.

Optionally, the time-frequency domain resources adopted by the first resource and the second resource are not overlapped, which is beneficial to avoiding confusion between the primary transmission resource and the retransmission resource. Optionally, the time-frequency domain resources adopted by the first resource and the second resource overlap, and may be distinguished by predefining different pilot ports, and optionally, the configuration information of the first resource and the second resource may be partially the same or completely different, which is not limited in the embodiment of the present application.

In this embodiment of the present application, the first information may include a random access Preamble code; optionally, the first information may further include an identifier of the terminal device and connection establishment information carried in the initial access random process; or, if the RRC reestablishment procedure is performed, the first information may further include connection state terminal equipment indication and connection establishment information, and in this embodiment of the present application, the two kinds of information are collectively referred to as PUSCH transmission information, that is, the two kinds of information may be information carried by resources for transmitting PUSCH. Optionally, the correspondence between the first resource and the second resource may also be referred to as a correspondence between the primary transmission resource and the retransmission resource of the first information.

In this 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.; likewise, 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, SSB information, etc. Optionally, the configuration information of the first resource and the configuration information of the second resource may further include information such as modulation coding mode and power. Alternatively, the configuration information of the first resource and the configuration information of the second resource may be configured in a semi-static configuration, or configuring complete resource information by compressed configuration methods such as configurational grantconfig and the like. As can be seen, the configuration information of the first resource and the configuration information of the second resource may be complete or incomplete resource information, and the more complete resource information is beneficial to the network device to detect the first information from the first resource and the second resource more quickly; fewer resource information, the signaling overhead is advantageously saved.

The time domain information comprises information such as index numbers of time units in a time domain; the frequency domain information comprises frequency information with a certain bandwidth on a frequency domain; the pilot frequency port information comprises information of an antenna port corresponding to a pilot frequency symbol, wherein pilot frequency signals are carried in the pilot frequency symbol; the code domain information includes information of code domain resources in the 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 configure only time-frequency domain information. In this way, signalling overhead is advantageously reduced. For example, the configuration information of the first resource adopts a configuration mode such as a configurational grantconfigug or a compressed configurational grantconfigug to configure complete resource information; the second resource configuration information includes only time-frequency domain information: timeDomainOffset (), timedomainalllocation (), frequencydomalnalllocation ().

Second resource configuration information {

timeDomainOffse()；

timeDomainAllocation()；

frequencyDomainAllocation()；

}。

For another example, the configuration information of the first resource and the configuration information of the second resource are complete resource information, so that the probability of correctly receiving the first information during retransmission can be greatly improved.

In an alternative embodiment, the correspondence between the first resource and the second resource is configurable by higher layer signaling, or broadcast configured, or predefined. Alternatively, the higher layer signaling may be radio resource control (Radio Resource Control, RRC) signaling. For example, the network device sends a first message, the terminal device receives the first message, where the first message is an RRC message, and the first message carries a list, and the list stores a correspondence between the first resource and the second resource.

In this embodiment, the correspondence between the first resource and the second resource may be indicated by any one or more of a plurality of optional embodiments.

In an optional embodiment, the configuration information of the first resource includes the second resource index number, so that it is known that the first resource has a corresponding relationship with the second resource. The second resource index number is a resource index number of configuration information of the second resource. The second resource index number may also be referred to as an index number of configuration information of the second resource, an index number of the second resource or an identifier of the second resource, etc. for distinguishing the identifier of the second resource, which is not limited in the embodiment of the present application. As shown in the following structural body, resource 2 is used for representing a second Resource index number, a corresponding Resource domain is added in the configuration information of the first Resource, and the Resource index number corresponding to the corresponding Resource domain is Resource 2 and represents that the first Resource and the second Resource have a corresponding relationship.

Configuration information { of the first resource

…

resource 2；

}。

In another alternative embodiment, the configuration information of the second resource includes a first resource index number. 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 referred to as an index number of configuration information of the first resource, an index number of the first resource or an identifier of the first resource, etc. for distinguishing the identifier of the first resource, which is not limited in the embodiments of the present application. For example, as shown in the lower structure body, resource 1 is used to represent a first Resource index number, a corresponding Resource domain is added in the configuration information of the second Resource, and the Resource index number corresponding to the corresponding Resource domain is Resource 1, which indicates that the first Resource and the second Resource have a corresponding relationship.

Configuration information { of the second resource

…

resource 1；

…

}。

In yet another alternative embodiment, the configuration information of the first resource may be placed as a domain in the configuration information of the second resource, or the configuration information of the second resource may be placed as a domain in the configuration information of the first resource.

In yet another alternative embodiment, the correspondence between the first resource and the second resource may be indicated by correspondence configuration information. The correspondence configuration information is information associating the first resource with the second resource configuration. As shown in the following structure, the correspondence configuration information includes that resource 1 is associated with resource 2.

The corresponding relation configuration information {

(resource 1；resource 2)；

…

}。

In yet another alternative embodiment, the correspondence between the first resource and the second resource may also be indicated by two or more embodiments described above. As shown in the following two structures, the configuration information of the first resource includes a second resource index number resource 2, and at the same time, the configuration information of the second resource includes a 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 embodiment, 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 for indicating that a corresponding relation exists between the first resource and the second resource.

In yet another alternative embodiment, the configuration information of the first resource and the configuration information of the second resource each include a first identifier, where the first identifier indicates that the resource is used for initial transmission when the first identifier is a first value, and indicates that the resource is used for retransmission when the first identifier is a second value. For example, the first identifier is 1 bit, the configuration information of the first resource and the configuration information of the second resource both include the first identifier, and when the value of the first identifier in the configuration information of the first resource is 1, the first identifier indicates that the first resource is used for initial transmission; when the value of the first identifier in the configuration information of the second resource is 0, the second resource is indicated to be used for retransmission, and the configuration information corresponds to the first resource which also contains the first identifier.

In this embodiment of the present application, the correspondence between the first resource and the second resource is one-to-one correspondence or many-to-one correspondence. When the first information is corresponding to the second resource, the first information can be the first resource identified by the second resource index number, and can be the resource identified by the second resource index number. The first resources and the second resources are in one-to-one correspondence, and unique first resources can be found based on the second resources, so that the acquisition of the merging gain of part or all of the first information is facilitated. The first resources correspond to a second resource, so that the second resource can be adopted when the first information borne by the first resources is partially or completely retransmitted, and the cost of the retransmission resource is reduced.

For example, the correspondence is indicated by the correspondence configuration information, and the resource index numbers of the plurality of first resources are resource 1,resource 3,resource 4, so that the structure of the correspondence configuration information may be as follows:

the corresponding relation configuration information {

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

…

}。

Thus, when the first information carried on the resource 1 and the resource 3 are received correctly, only the resource 4 is not received correctly, part or all of the retransmitted first information corresponding to the resource 4 can be detected on the resource 2, so that the combined receiving of the signals on the resource 2 is facilitated.

In this embodiment of the present application, the correspondence between the first resource and the second resource may be determined by adopting the correspondence between the first resource index number and the second resource index number, and also may be a correspondence between a resource for transmitting a Preamble code in the first resource and a resource for transmitting a Preamble code in the second resource. That is, only the correspondence between the resources for transmitting the Preamble code is configured, and the network device and the terminal device can identify the correspondence between the resources for transmitting the PUSCH twice in the first resource and the second resource based on the correspondence. In this way, it is advantageous to avoid having to predefine resources for transmitting PUSCH, i.e. to reduce the resources reserved for transmitting PUSCH. Optionally, in the embodiment indicated by the above various correspondence, the first resource index number may be replaced by a primary resource index number of the Preamble code, and the second resource index number may be replaced by a retransmission resource index number of the Preamble code.

Alternatively, in this embodiment, separate Preamble resource pools may be configured for the Preamble code of the initial transmission and the Preamble code of the retransmission, respectively. The Preamble code resources may be any one or a combination of time/frequency/code resources. The first N Preamble code (N is a positive integer, for example, n=50, N may be a network configuration or a protocol convention) resources on one R0 resource are used for initial transmission, and the Preamble code (n=50, i.e., preamble codes of 51-64) resources after n+1 are used for retransmission. The first N Preamble code resources and the n+1 subsequent Preamble code resources have a corresponding relationship, and the first Preamble code resource and the retransmission Preamble code resource may have a one-to-one correspondence, or may have a many-to-one correspondence. Alternatively, in the case of many-to-one, each X resources of the primary Preamble code corresponds to 1 resource of the retransmission Preamble code, and X depends on the value of N. For example, assuming that n=48 total resources of 64 Preamble codes, the resources of the primary transmission Preamble code are 48, the resources of the retransmission Preamble code are 16, and each 3 resources of the primary transmission Preamble code corresponds to one resource of the retransmission Preamble code, namely, the resources {1-3} of the primary transmission Preamble code correspond to the resources {49} of the retransmission Preamble code, the resources {4-6} of the primary transmission Preamble code correspond to the resources {50} of the retransmission Preamble code, …, and so on. When the network side judges the primary transmission or retransmission according to the resource of the received Preamble code, if the primary transmission or retransmission is the retransmission, the corresponding primary transmission is found based on the corresponding relation, thereby being beneficial to the combination and the reception. The R0 resource may be a resource for carrying a random access opportunity, for example, a part of time-frequency resource block for transmitting a Preamble code, etc.

Optionally, in this embodiment, a Preamble code resource pair may be configured for a resource of the primary transmission Preamble code and a resource of the retransmission Preamble code, and based on the Preamble code resource pair, a correspondence between the resource of the primary transmission Preamble code and the resource of the retransmission Preamble code is determined, so as to obtain a PUSCH resource associated with the twice transmission Preamble code, thereby being beneficial to merging and receiving data carried by the PUSCH resource.

In another optional embodiment, the correspondence between the first resource and the second resource is a correspondence between a resource for transmitting PUSCH in the first resource and a resource for transmitting PUSCH in the second resource. That is, only the correspondence between the primary transmission resource that transmits PUSCH and the retransmission resource that transmits PUSCH is configured, and further, the correspondence between the first resource and the second resource is identified by the correspondence. In this way, it is advantageous to reduce the resources reserved for transmitting Preamble codes. Optionally, in the embodiments indicated by the above various correspondence relationships, the first resource index number may be replaced with a primary resource index number for transmitting PUSCH, and the second resource index number may be replaced with a retransmission resource index number for transmitting PUSCH.

In yet another alternative embodiment, the correspondence between the first resource and the second resource is indicated by a correspondence between a resource for transmitting a Preamble code in the first resource and a resource for transmitting a PUSCH in the second resource, and a resource for transmitting a Preamble code in the second resource and a resource for the PUSCH. That is, the primary transmission resource and the retransmission resource both include a resource for transmitting the Preamble code and a resource for the PUSCH, and the corresponding relationship also includes a corresponding relationship between the two resources. Optionally, in the embodiment indicated by the above various correspondence, the first resource index number may be replaced by a Preamble code primary transmission resource index number and a PUSCH transmission primary transmission resource index number, and the second resource index number may be replaced by a Preamble code retransmission resource index number and a PUSCH transmission retransmission resource index number. For example, the correspondence between the first resource and the second resource is indicated by correspondence configuration information, preamble resource 1 represents a primary transmission resource index number of the Preamble code, preamble resource represents a retransmission resource index number of the Preamble code, PUSCH resource 1 represents a primary transmission resource index number for transmitting PUSCH, PUSCH resource 2 represents a retransmission resource index number for transmitting PUSCH, and the correspondence configuration information may be expressed as:

The corresponding relation configuration information {

(Preamble resource 1；Preamble resource 2)；

(PUSCH resource 1；PUSCH resource 2)；

…

}。

In this embodiment of the present application, the preset time unit is a period of time after the first information is sent, and the timing start point of the preset time unit may be later than the reception completion time of the first information on the first resource, for example, the preset time unit may be X symbols/time slots/milliseconds later than the reception completion time of the first information on the first resource; optionally, the duration of the preset time unit may be a monitoring window of a random access response (Random Access Response, RAR), or a duration less than a duration of a RAR monitoring window of a 4-step random access, which is not limited in the embodiments of the present application.

Based on the above concepts, the following description will proceed with reference to the accompanying drawings. .

Referring to fig. 2, fig. 2 is a flow chart of an information transmission method provided in an embodiment of the present application, and as shown in fig. 2, the information transmission method is illustrated 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 transmits first information on a first resource, and the network device receives the first information on the first resource;

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

For example, before 201, the network device sends a first message to the terminal device, the first message carrying a correspondence between the first resource and the second resource. Accordingly, in the step 201, when the network device receives the first information, the network device may detect the first information, if the detection is successful, send a response message of the first information, and if the detection fails, not send a response message of the first information.

Further, in the step 202, after the network device receives 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, that is, the received signal on the primary transmission resource, according to the corresponding relationship, so as to combine the two received signals, and realize the merging gain for part or all of the first information.

It can be seen that, in the 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 in the preset time unit, part or all of the first information is sent again on the second resource corresponding to the first resource. The two transmissions are respectively transmitted on the first resource and the second resource with the corresponding relation, so that the network equipment is beneficial to combining the first information received twice on the first resource and the second resource. That is, in the embodiment of the present application, the network device may obtain the combining gain between part or all of the first information carried by the second resource and the first information carried by the first resource even if the first information carried by the first resource cannot be correctly demodulated.

In one possible example, the correspondence between the first resource and the second resource is configured by higher layer signaling, or broadcast configured, or predefined.

In one possible example, the first resource is any one of the following resources: resources for transmitting a physical downlink shared channel PUSCH; or, resources for transmitting preamble codes and PUSCH. For example, the first resource may be a resource for transmitting MsgA in a random access procedure.

The second resource is any one of the following resources: resources for transmitting PUSCH, or resources for transmitting Preamble code and PUSCH. For example, the second resource may be a resource for retransmitting part or all of the information in the MsgA. The second resource may have a correspondence with the first resource, and the terminal device may obtain the position of the second resource according to the position of the first resource.

In one 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 one possible example, the correspondence existing 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 comprises the second resource index number, and the configuration information of the second resource comprises the first resource index number or corresponding relation configuration information;

the second resource index number is a resource index number of configuration information of the second resource; the first resource index number is a resource index number of configuration information of the first resource; the correspondence configuration information is information associating the first resource with the second resource configuration.

In one 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 for indicating that a corresponding relation exists between the first resource and the second resource.

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

The corresponding relation between the resources used for sending the Preamble codes in the first resources and the resources used for sending the Preamble codes in the second resources;

a correspondence between resources used for sending the PUSCH in the first resource and resources used for sending the PUSCH in the second resource;

and the corresponding relation between the resource for sending the Preamble code and the resource for sending the PUSCH in the first resource and the resource for sending the Preamble code and the resource for sending the PUSCH in the second resource.

In one 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 the above possible examples may be referred to in the detailed description of the relevant conceptual section, and will not be described in detail herein.

In the following, a specific scenario is further described, where the first information is MsgA in the random access procedure, and correspondingly, when the network device receives the MsgA correctly, the network device may send scheduling information as a response message of the first information to the terminal device, so that the terminal device uses the scheduling information to send information such as identification of the terminal device and connection establishment. Specifically, as shown in fig. 3, the information transmission method may include the following steps:

In part 301, the network device broadcasts a first message carrying resource configuration information for a resource that transmits MsgA.

The resource configuration information includes a correspondence configuration information field, where the correspondence configuration information field indicates a correspondence between a primary transmission resource of the primary transmission MsgA and a retransmission resource of the retransmission MsgA.

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

in part 303, the network device receives the MsgA on the primary transmission resource and detects the MsgA; executing the part 304a when the MsgA detection is successful, and returning scheduling information; when the MsgA detection fails, the scheduling information is not sent, and the terminal equipment executes the 304b part;

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

In 304b, when the terminal device does not receive the scheduling information in the preset time unit, the terminal device resends the MsgA or part of the information in the MsgA on the retransmission resource corresponding to the primary transmission resource. In a specific example, the partial information in the retransmitted MsgA may include a portion that was not properly demodulated by the network device.

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

Optionally, when the network device receives the MsgA, it may determine whether the resource for transmitting the MsgA is a primary transmission resource or a retransmission resource, and if the resource is a retransmission resource, it may query the primary transmission resource corresponding to the retransmission resource, so as to implement a partial or full combining gain of the MsgA.

It can be seen that in the embodiment of the present application, the terminal device sends MsgA on the primary transmission resource, and when no scheduling information is received in the preset time unit, the terminal device sends MsgA again on the retransmission resource. It can be seen that in the embodiment of the present application, the terminal device does not receive the scheduling information, and may also have resources to retransmit the MsgA, so that the network device cannot identify the terminal device, and can obtain a partial or complete combining gain of the Msg a even if the network device cannot transmit the scheduling information.

The first information sent twice is respectively sent on the first resource and the second resource with the corresponding relation, so that the network equipment is favorable for combining the first information received twice on the first resource and the second resource. That is, in the embodiment of the present application, the network device may obtain the combining gain between part or all of the first information carried by the second resource and the first information carried by the first resource even if the first information carried by the first resource cannot be correctly demodulated. Since the steps performed by the terminal device have been described in detail in the foregoing method embodiments, details of the processing of the first information by the terminal device will not be described herein again, and reference may be made to the descriptions in the foregoing method embodiments.
