It is to be understood that reference herein to "a number" means one or more and "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. For ease of understanding, the application scenarios referred to in the present application will be briefly described below.

Referring to fig. 1, a schematic structural diagram of a wireless communication system according to an exemplary embodiment of the present application is shown. As shown in fig. 1, the wireless communication system is a communication system based on a cellular mobile communication technology, and may include: several terminals 110 and base stations 120.

Terminal 110 may refer to, among other things, a device that provides voice and/or data connectivity to a user. The terminal 110 may communicate with one or more core networks via a Radio Access Network (RAN), and the terminal 110 may be an internet of things terminal, such as a sensor device, a mobile phone (or referred to as a "cellular" phone), and a computer having the internet of things terminal, and may be a fixed, portable, pocket, handheld, computer-included, or vehicle-mounted device, for example. For example, a Station (STA), a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), an Access point, a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Equipment (User Terminal), a User Agent (User Agent), a User Equipment (User Device), or a User Terminal (UE). Alternatively, the terminal 110 may be a device of an unmanned aerial vehicle, a vehicle-mounted device, or the like.

The base station 120 may be a network side device in a wireless communication system. The wireless communication system may also be a 5G system, which is also called a New Radio (NR) system. Alternatively, the wireless communication system may be a next-generation system of a 5G system.

Optionally, the base station 120 may be a base station (gNB) adopting a centralized distributed architecture in the 5G system. When the base station 120 employs a centralized Distributed architecture, it typically includes a Central Unit (CU) and at least two Distributed Units (DU). A Packet Data Convergence Protocol (PDCP) layer, a Radio Link layer Control Protocol (RLC) layer, and a Media Access Control (MAC) layer are provided in the central unit; a Physical (PHY) layer protocol stack is disposed in the distribution unit, and the embodiment of the present application does not limit the specific implementation manner of the base station 120.

The base station 120 and the terminal 110 may establish a radio connection over a radio air interface. In different embodiments, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G next generation mobile communication network technology standard.

Optionally, the wireless communication system may further include a network management device 130.

The base stations 120 may be respectively connected to the network management apparatus 130. The network Management device 130 may be a Core network device in a wireless communication system, for example, the network Management device 130 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the Network management device may also be other core Network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), a Home Subscriber Server (HSS), or the like. The embodiment of the present application is not limited to the implementation form of the network management device 130.

In the wireless communication scenario shown in fig. 1, when the terminal transmits data to the base station, the terminal may transmit corresponding data in the PUCCH and the PUSCH, and accordingly, the base station may receive the data transmitted by the terminal in the PUCCH and the PUSCH. Taking the example that UCI information is carried in PUCCH, after a base station sends PDSCH data to a terminal through a Physical Downlink Shared Channel (PDSCH), the terminal needs to feed back whether the PDSCH data sent by the base station is correctly received, where the terminal may perform Acknowledgement (ACK) or negative acknowledgement (Non-ACK) feedback through PUCCH. Or, the base station may instruct the terminal to perform periodic or quasi-periodic Channel State Information (CSI) measurement, and the terminal needs to feed back a CSI measurement result to the base station through the PUCCH. For the ACK, NACK or CSI measurement result fed back, these pieces of information may all be referred to as UCI information. When the time domain resource of the PUCCH for transmitting the UCI information by the terminal conflicts with the time domain resource occupied by the PUSCH indicated by the base station, the terminal may multiplex the UCI information on the PUSCH for transmission.

In order to improve the transmission reliability of the PUSCH, the NR system also introduces repeated transmission of the PUSCH, i.e. the PUSCH carrying the same data is transmitted multiple times over a period of time. From the perspective of time domain resources, in R15, the repeated transmission of the PUSCH is based on slot-level repeated transmission, and in R16, the repeated transmission of the PUSCH across slots is introduced, that is, the base station indicates the time domain position occupied by each repeated transmission by configuring the Orthogonal Frequency Division Multiplexing (OFDM) symbol length occupied by each repeated transmission and the number of times of repeated transmission.

When the terminal performs repeated transmission in the PUSCH, the time domain resource actually adopted by the terminal in the PUSCH may be different from the time domain resource configured by the base station. For example, when a time domain resource used for a certain time of repeated transmission in the time domain resources configured by the base station crosses a slot boundary or collides with a DownLink Data (DL) symbol configured by the base station, the terminal needs to segment (segment) the time domain resource configured by the base station for repeated transmission according to the slot boundary and the DL symbol and transmit the time domain resource included in the segmented PUSCH.

Wherein, we can refer to the time domain resource of the repeated transmission PUSCH configured by the base station as: time domain resources for nominal repetition (nominal retransmission) transmission, also known as nominal pusch. After the terminal segments the time domain resource of the nominal repeat transmission allocated by the base station, the obtained multiple PUSCHs are transmitted, the repeat transmission at this time may be referred to as actual repeat transmission, and the time domain resource of the actual repeat transmission may be referred to as an actual PUSCH (actual PUSCH).

Please refer to fig. 2, which illustrates a schematic structural diagram of a time domain resource included in a PUSCH according to an exemplary embodiment of the present application. As shown in fig. 2, it includes slot one 201, slot two 202, nominal PUSCH 203, and actual PUSCH 204. As can be seen from fig. 2, the number of repeated transmissions of the PUSCH configured by the base station is 3, the starting position is the 6 th OFDM symbol of the slot one 201, and the length of each transmission is 6, when the terminal obtains the repeated transmission of the PUSCH configured by the base station, that is, the terminal obtains the nominal PUSCH 203 (including the nominal PUSCH 1, the nominal PUSCH 2, and the nominal PUSCH 3), the terminal may segment the nominal PUSCH 203 according to the time domain resource situation of the PUSCH to obtain the actual PUSCH 204 (including the actual PUSCH 1, the actual PUSCH 2, the actual PUSCH 3, and the actual PUSCH 4), where the actual PUSCH 204 shown in fig. 2 is only an exemplary result, and does not represent all the situations. When the terminal transmits PUSCH data, the transmission may be performed according to the time domain resources included in the actual PUSCH 204.

At present, there is no perfect solution for how a terminal performs data transmission when a time domain resource adopted for data transmission is collided. In a possible implementation manner, when the terminal determines whether the repeated transmission of the PUCCH and the PUSCH for carrying the UCI conflicts, the terminal compares the PUCCH for carrying the UCI with the time domain resource occupied by the nominal PUSCH configured by the base station, and if the time domain resources of the PUCCH and the time domain resource of the nominal PUSCH conflict, the terminal may multiplex the UCI in the PUCCH to the PUSCH for transmission. When the terminal judges whether the repeated transmission of the PUCCH bearing the UCI and the PUSCH conflicts or not, the repeated transmission of the PUCCH bearing the UCI and the PUSCH is compared with a nominal PUSCH configured by the base station, when the nominal PUSCH configured by the base station needs to be segment, if the nominal PUSCH configured by the base station is after the segment, the occupied time domain resource is small, the actual PUSCH obtained after the segment does not conflict with the PUCCH, so that the time domain resource selection error when the PUCCH is multiplexed on the PUSCH for transmission is caused, and the reliability of information transmission between the terminal and the base station is reduced.

In order to provide a terminal to better multiplex UCI in a PUSCH for transmission and improve reliability of information transmission, embodiments of the present application provide a solution, which can reduce an error rate of PUSCH transmission while multiplexing UCI in a PUSCH for transmission. Referring to fig. 3, a flowchart of a method for transmitting information according to an exemplary embodiment of the present application is shown, where the method may be applied to the wireless communication system shown in fig. 1 and executed by a terminal in the system. As shown in fig. 3, the information transmission method may include the following steps:

step 301, obtaining a first time domain resource, where the first time domain resource is determined by the terminal from the time domain resource of the PUSCH repeatedly transmitted and configured by the network device.

Optionally, the first time domain resource may also be referred to as an actual repeatedly transmitted time domain resource, and the time domain resource configured by the network device for repeatedly transmitting the PUSCH may also be referred to as a time domain resource for nominal repeatedly transmitted, that is, the actual repeatedly transmitted time domain resource is an actual PUSCH time domain resource, and the nominal repeatedly transmitted time domain resource is a nominal PUSCH, and after receiving the nominal PUSCH, the terminal may segment the nominal PUSCH according to the manner shown in fig. 2, so that each OFDM symbol corresponding to the actual PUSCH in each OFDM symbol corresponding to the nominal PUSCH can be identified.

Optionally, the first time domain resource is formed by each OFDM symbol corresponding to an actual PUSCH. For example, in the slot structure shown in fig. 2, the first time domain resource may be a time domain resource composed of OFDM symbols corresponding to the actual PUSCH 1, the actual PUSCH 2, the actual PUSCH 3, and the actual PUSCH 4.

Step 302, obtaining a second time domain resource, where the second time domain resource is a time domain resource that is configured by the network device to the terminal and used for bearing the target uplink information in the physical uplink control channel PUCCH.

The network device may configure the PUCCH to the terminal, and the terminal may transmit the target uplink information in the PUCCH configured by the network device after obtaining the PUCCH configured by the network device. The second time domain resource may be a time domain resource used when the target uplink information is transmitted this time, and may also be a time domain resource composed of OFDM symbols used when the target uplink information is transmitted this time, and the target uplink information may refer to information carried in the PUCCH this time. That is, the terminal may acquire the time domain resource corresponding to the PUCCH according to the PUCCH configured by the network device, and use the acquired time domain resource of the PUCCH as the second time domain resource.

Step 303, when the first time domain resource conflicts with the second time domain resource, multiplexing transmission is performed on the PUSCH and the target uplink information on the first time domain resource.

Time domain resources adopted by the terminal in the process of transmitting the PUSCH and the PUCCH may coincide to cause collision between the PUSCH and the PUCCH, and at the moment, the terminal can multiplex and transmit target uplink information on the first time domain resources together with the PUSCH. The collision between the first time domain resource and the second time domain resource may mean that OFDM symbols included in the first time domain resource and the second time domain resource are overlapped.

Referring to fig. 4, a schematic diagram of a time domain resource conflict according to an exemplary embodiment of the present application is shown. As shown in fig. 4, a first time domain resource 401, a second time domain resource 402, a third time domain resource 403, and a fourth time domain resource 404 are included. Wherein the first time domain resource 401 and the second time domain resource 402 are in conflict, and the third time domain resource 403 and the fourth time domain resource 404 are in conflict.

In the embodiment of the application, the terminal acquires the time domain resource actually transmitted repeatedly in the PUSCH, and the network device configures the time domain resource for the terminal to carry the target uplink information in the PUCCH, and when the time domain resource actually transmitted repeatedly in the PUSCH and the time domain resource actually transmitted repeatedly in the PUSCH collide with each other, the target uplink information is multiplexed and transmitted. Therefore, the terminal in the application judges whether the terminal conflicts with the PUCCH or not according to the time domain resource corresponding to the actual PUSCH after the segment, and selects the time domain resource corresponding to the actual PUSCH which conflicts for multiplexing, so that the problem of time domain resource selection error caused by large time domain resource occupied by the actual PUSCH before the segment is solved, and the reliability of information transmission between the terminal and the base station is improved.

Optionally, the first time domain resource includes a time domain resource for independently transmitting a PUSCH;

when the first time domain resource conflicts with the second time domain resource, multiplexing transmission is carried out on the PUSCH and the target uplink information on the first time domain resource, and the method comprises the following steps:

when the first time domain resource conflicts with the second time domain resource, acquiring a third time domain resource, wherein the third time domain resource comprises a time domain resource which is used for independently transmitting a PUSCH and is located by the time domain resource where the first time domain resource conflicts with the second time domain resource;

and when the PUCCH and the PUSCH in the third time domain resource meet the multiplexing timing requirement, multiplexing transmission is carried out on the PUSCH and the target uplink information on the third time domain resource.

Optionally, when the third time domain resource includes at least two time domain resources for independently transmitting the PUSCH, and when the PUCCH and the PUSCH in the third time domain resource meet the multiplexing timing requirement, multiplexing transmission is performed on the PUSCH and the target uplink information on the third time domain resource, including:

and multiplexing and transmitting the PUSCH and the target uplink information on the time domain resource of the first independent transmission PUSCH in sequence in the time domain resources of at least two independent transmission PUSCHs.

Optionally, the multiplexing transmission of the PUSCH and the target uplink information on the first time domain resource includes:

calculating a target quantity according to the number of first resources in the time domain resources configured by the network equipment for repeatedly transmitting the PUSCH, wherein the target quantity is the quantity of the first resources occupied in the first time domain resources when the target uplink information carries out multiplexing transmission on the PUSCH and the target uplink information on the first time domain resources;

and when multiplexing transmission is carried out on the PUSCH and the target uplink information on the first time domain resource, transmitting the target uplink information on the first time domain resource according to the target quantity.

Optionally, calculating the target number according to the number of the first resources in the time domain resources of the PUSCH repeatedly transmitted configured by the network device, includes:

acquiring a target time domain resource in the time domain resources of the PUSCH (physical uplink shared channel) which are configured by the network equipment and repeatedly transmitted, wherein the target time domain resource is the time domain resource which is configured by the network equipment and repeatedly transmitted and corresponds to the transmission resource in which the first time domain resource conflicts with the second time domain resource;

calculating the target quantity according to the number of the first resources in the target time domain resources; the number of the first resources is the number of all first resources used for transmitting PUSCH data in the target time domain resource; or the number of the first resources is the number of the first resources left after subtracting the number of the first resources occupied by the second resources from the target time domain resources.

Optionally, the first resource is any one of a time-frequency resource unit RE, a subcarrier, and an OFDM symbol.

Optionally, the second resource includes at least one of a demodulation reference signal DMRS or a phase tracking reference signal PTRS.

Optionally, the method further comprises:

receiving a time domain resource of repeated transmission PUSCH configured by network equipment;

acquiring a first time domain resource, comprising:

and acquiring the first time domain resource from the repeatedly transmitted time domain resource configured by the network equipment according to the fixed resource information, wherein the fixed resource information comprises the time slot boundary, the uplink and downlink configuration and the resource information indicated by the unavailable resource.

Optionally, the target uplink information includes a PUCCH carrying ACK/NACK for PDSCH feedback, or a PUCCH carrying an uplink scheduling request SR corresponding to a PUSCH, or any one of a PUCCH and a PUSCH carrying CSI.

All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present application, and the present application embodiment is not described in detail again.

In a possible implementation manner, the first time domain resource may further include a time domain resource for independently transmitting a PUSCH (hereinafter referred to as an independent time domain resource). The scheme shown in fig. 3 is described below by taking the example that the first time domain resource includes a time domain resource for independently transmitting a PUSCH.

Referring to fig. 5, a flowchart of a method for transmitting information according to another embodiment of the present application is shown, where the method may be applied to the wireless communication system shown in fig. 1 and executed by a terminal in the system. As shown in fig. 5, the information transmission method may include the following steps:

step 501, receiving a time domain resource of a repeated transmission PUSCH configured by a network device.

The network device may send the time domain resource usable by the terminal in the PUSCH to the terminal through Downlink Control Information (DCI), and accordingly, the terminal may demodulate the Information in the DCI to obtain the time domain resource nominally repeatedly transmitting the PUSCH.

Step 502, according to the fixed resource information, obtaining the first time domain resource from the repeatedly transmitted time domain resource configured by the network device, where the fixed resource information includes resource information indicated by the time slot boundary, the uplink and downlink configuration, and the unavailable resource.

Wherein, the time domain resource configured to the terminal by the network device does not represent all the time domain resources that can be used by the terminal. For example, the network device needs to transmit some uplink and Downlink configurations (e.g., Downlink (DL) symbols, etc.) in some time domain resources of the time domain resources, and needs to occupy some time domain resources therein, so that when the terminal actually uses the time domain resources configured to the terminal by the network device, the unused time domain resources are also selected to be used. Or, the network device needs to transmit some unavailable resources (e.g., system data) in some of the time domain resources and also needs to occupy some of the time domain resources, so that when the terminal actually uses the time domain resources configured for the terminal by the network device, the unused time domain resources are also selected for use.

The terminal may select, from the time domain resources configured by the network device and nominally repeatedly transmitted, a time domain resource that can be used for PUSCH transmission, where the time domain resource that can be used for PUSCH transmission is the time domain resource determined by the terminal to be actually repeatedly transmitted, and accordingly, the terminal may obtain the time domain resource determined by itself to be actually repeatedly transmitted (i.e., the first time domain resource). The first time domain resource may include an independent time domain resource.

Referring to fig. 6, a schematic structural diagram of a timeslot structure according to an exemplary embodiment of the present application is shown, as shown in fig. 6, where a first timeslot 601, a second timeslot 602, and a third timeslot 603 are included. Nominal PUSCH 604, actual PUSCH 605. As can be seen from fig. 6, the network device configures the terminal with a repeated transmission number of 3, where the transmission start position is the 11 th OFDM symbol of the first slot 601, and each transmission lasts for multiple transmissions of the PUSCH with a length of 6 OFDM symbols. I.e., the time domain resources configured for nominal repeated transmission by the network device corresponding to the 12 th OFDM symbol of the first slot 601 through the 1 st OFDM symbol of the third slot 603.

In the time domain resource of the nominal repeated transmission, the network device has a DL symbol in the 9 th to 11 th OFDM symbols in the second slot 602, and the terminal cannot transmit the PUSCH in the time domain resource having the DL symbol, so that the time domain resource of the repeated transmission actually used by the terminal does not include the 9 th to 11 th OFDM symbols in the second slot 602. In addition, since the terminal cannot be used for PUSCH transmission at a slot boundary, the terminal also needs to re-partition the PUSCH on behalf 504 when actually performing PUSCH transmission.

After the terminal re-partitions the nominal PUSCH 604, an actual PUSCH 605 as included in fig. 6 may be obtained, and when the terminal actually transmits the PUSCH, the terminal may transmit using the time domain resources included in the actual PUSCH 605. Wherein, the first time domain resource is all the time domain resources contained in the actual PUSCH 605 (i.e. the OFDM symbol numbered 11 in the first slot 601 to the OFDM symbol numbered 7 in the second slot 602, and the OFDM symbol numbered 11 in the second slot 602 to the OFDM symbol numbered 0 in the third slot 603), and correspondingly, each independent time domain resource contained in the actual PUSCH 605 may be: a first independent time domain resource, a second independent time domain resource, a third independent time domain resource, a fourth independent time domain resource and a fifth independent time domain resource. Wherein the first independent time domain resource: the OFDM symbols numbered 11-13 in the first slot 601; second independent time domain resource: the OFDM symbols numbered 0-2 in the second slot 602; third independent time domain resource: the OFDM symbols numbered 3-7 in the second slot 602; fourth independent time domain resource: the OFDM symbols numbered 11-13 in the second slot 602; fifth independent time domain resource: the OFDM symbol numbered 0 in the third slot 603. Optionally, the terminal may obtain the first time domain resource, and may also obtain each independent time domain resource in the first time domain resource.

Step 503, acquiring a second time domain resource, where the second time domain resource is a time domain resource configured by the network device to the terminal for bearing the target uplink information in the physical uplink control channel PUCCH.

The manner of obtaining the second time domain resource in this step may refer to the description in step 302 in the embodiment shown in fig. 2, which is not repeated here.

Optionally, the target uplink Information may also include a PUCCH carrying an ACK/NACK for PDSCH feedback, or a PUCCH carrying an uplink Scheduling Request (SR) corresponding to the PUSCH, or any Information of the PUCCH or the PUSCH carrying Channel State Information (CSI).

Step 504, when the first time domain resource conflicts with the second time domain resource, a third time domain resource is obtained.

The third time domain resource comprises a time domain resource which is used for independently transmitting the PUSCH and is located by the time domain resource where the first time domain resource conflicts with the second time domain resource. Or, the third time domain resource may be an independent time domain resource including a fourth time domain resource in each independent time domain resource, and the fourth time domain resource is a time domain resource in which the first time domain resource and the second time domain resource collide.

The terminal may obtain a time domain resource where the first time domain resource conflicts with the second time domain resource, and obtain a time domain resource (i.e., a third time domain resource) containing the time domain resource in the first time domain resource according to the time domain resource. As shown in fig. 6, a second time domain resource 606 corresponding to the PUCCH is further included, where the second time domain resource 606 conflicts with the first time domain resource. Optionally, the terminal may determine whether the first time domain resource and the second time domain resource conflict, and if so, may obtain the third time domain resource.

As shown in fig. 6, the first time domain resource includes a first time domain resource and a second time domain resource, and the time domain resource where the first time domain resource and the second time domain resource collide is a time domain resource composed of OFDM symbols numbered 11 to 13 in the first time slot, and at this time, the third time domain resource acquired by the terminal is a first independent time domain resource, that is, a time domain resource including OFDM symbols numbered 11 to 13 in the first time slot. Optionally, if the time domain resource where the first time domain resource and the second time domain resource collide with each other is a time domain resource composed of OFDM symbols numbered 11 to 12 in the first time slot, the third time domain resource acquired by the terminal is also a first independent time domain resource, that is, a time domain resource including OFDM symbols numbered 11 to 13 in the first time slot.

And 505, when the PUCCH and the PUSCH in the third time domain resource meet the multiplexing timing requirement, multiplexing and transmitting the PUSCH and the target uplink information on the third time domain resource.

The terminal can also detect the timing relationship between the PUCCH and the PUSCH in the third time domain resource, determine whether the timing relationship between the PUCCH and the PUSCH in the third time domain resource meets the multiplexing timing requirement, multiplex and transmit the PUSCH and the target uplink information on the third time domain resource when the PUCCH and the PUSCH in the third time domain resource meet the multiplexing timing requirement, and do not multiplex and transmit the PUSCH and the target uplink information on the third time domain resource when the PUCCH and the PUSCH in the third time domain resource do not meet the multiplexing timing requirement. Optionally, when the terminal determines whether the timing relationship between the overlapped PUCCH and PUSCH meets the multiplexing timing requirement, the specification in NR Rel-15 may be followed, which is not limited in this embodiment of the present application.

In a possible implementation manner, the third time domain resource may further include at least two independent time domain resources. Optionally, when the third time domain resource includes at least two independent time domain resources and the terminal determines that the two independent time domain resources both meet the multiplexing timing requirement, the terminal may sequentially multiplex and transmit the PUSCH and the target uplink information on the first independent time domain resource in the at least two independent time domain resources. That is, the terminal may determine whether the timing relationship between the PUCCH and the PUSCH in each independent time domain resource meets the multiplexing timing requirement, and when the timing relationship between the PUCCH and the PUSCH in one of the independent time domain resources meets the multiplexing timing requirement, the terminal may multiplex and transmit the PUSCH and the target uplink information on the independent time domain resource.

Please refer to fig. 7, which illustrates a schematic diagram of an exemplary embodiment of the present application relating to another PUCCH and PUSCH coincidence of fig. 6. As shown in fig. 7, a first time slot 701, a second time slot 702, and a third time slot 703 are included. A nominal PUSCH 704, an actual PUSCH 705, a second time domain resource 706, a third time domain resource 707, a first independent time domain resource 708, a second independent time domain resource 709. The terminal may obtain that the third time domain resource 707 is a time domain resource including OFDM symbols numbered 11 in the first slot 701 to numbered 2 in the second slot 702 through the above steps. At this time, the third time domain resource 707 includes a first independent time domain resource (the time domain resource of the OFDM symbol with the number of 11-13 in the first slot 701), a second independent time domain resource (the time domain resource of the OFDM symbol with the number of 0-2 in the second slot 702), and the terminal can determine the timing relationship between the PUCCH and the PUSCH in the first independent time domain resource and determine the timing relationship between the PUCCH and the PUSCH in the second independent time domain resource, and if the terminal determines the first independent time domain resource and the second independent time domain resource at this time, the timing relationship between the PUCCH and the PUSCH in the first independent time domain resource 708 meets the multiplexing timing requirement; the timing relationship of the PUCCH and the PUSCH in the second independent time domain resource 709 also meets the multiplexing timing requirement; at this time, the terminal may select the first independent time domain resource 708 in the top order for multiplexing transmission, that is, perform multiplexing transmission on the PUSCH and the target uplink information on the first independent time domain resource 708.

Optionally, when the terminal performs multiplexing transmission on the PUSCH and the target uplink information in a certain time domain resource, the terminal further needs to calculate the number of resources occupied by the target uplink information in the time domain resource, and transmit the target uplink information on the time domain resource according to the calculated number of resources.

For example, if the terminal multiplexes the PUSCH and the target uplink information on the first time domain resource, the terminal may calculate the target number according to the number of the first resources in the time domain resource for which the nominal retransmission is performed, where the target number is the number of the first resources occupied in the first time domain resource when the target uplink information multiplexes the PUSCH and the target uplink information on the first time domain resource. Optionally, the first Resource is any one of a time frequency Resource Element (RE), a subcarrier, and an OFDM symbol. For example, the terminal may calculate the number of REs occupied by the target uplink information on the first time domain resource according to the number of REs in the time domain resource of the nominal repeated transmission. Or, the terminal may calculate the number of subcarriers occupied by the target uplink information on the first time domain resource according to the number of subcarriers in the time domain resource of the nominal repeated transmission. Or, the terminal may calculate the number of OFDM symbols occupied by the target uplink information on the first time domain resource according to the number of OFDM symbols in the time domain resource that is nominally repeatedly transmitted. This is not limited by the examples of the present application.

In a possible implementation manner, when the terminal calculates the target number, the terminal may perform the calculation in the following manner. The terminal may obtain a target time domain resource in the nominally repeatedly transmitted time domain resources configured by the network device. The target time domain resource is a nominally repeatedly transmitted time domain resource corresponding to an actual transmission resource where the first time domain resource conflicts with the second time domain resource. And the terminal calculates the target quantity according to the number of the first resources in the target time domain resources. Optionally, the number of the first resources is the number of all first resources used for transmitting PUSCH data in the target time domain resource; or the number of the first resources is the number of the first resources left after subtracting the number of the first resources occupied by the second resources from the target time domain resources. And finally, the terminal can perform multiplexing transmission on the PUSCH and the target uplink information on the first time domain resource according to the second resource number. Alternatively, the second resource may include at least one of a Demodulation Reference Signal (DMRS) and a Phase Tracking Reference Signal (PTRS).

Still taking the example shown in fig. 7 as an example, the time domain resource finally adopted by the terminal for multiplexing and transmitting the PUSCH and the target uplink information is the first independent time domain resource 708, and when the terminal performs multiplexing and transmitting the PUSCH and the target uplink information on the first independent time domain resource, the number of resources occupied by the target uplink information in the first independent time domain resource, which are the same as the first resource, may be calculated.

The terminal may obtain a target time domain resource in the time domain resources configured by the network device for the nominal repeated transmission, that is, a nominal PUSCH 1 in the nominal PUSCH 704 corresponding to the first independent time domain resource 708. For example, the terminal may search and obtain a time domain resource (nominal PUSCH 1) corresponding to the nominal PUSCH containing the first independent time domain resource in the nominal PUSCH 704 according to the OFDM symbol contained in the first independent time domain resource.

Optionally, the terminal obtains the number of the first resources in the nominal PUSCH 1, and calculates the target number according to the number of the first resources in the nominal PUSCH 1. Taking the first resource as RE as an example, the terminal may calculate the target quantity Q with reference to the formula [ 1 ]_ACK。

Wherein, O_ACKIs the number of HARQ-ACK (Hybrid Automatic Repeat request-ACK) bits, L_ACKIs the number of CRC bits, β_offsetIs a code rate compensation factor, alpha is a parameter configured by the higher layer signaling for limiting the upper limit of the number of the second resources, M_SC(l) Is the number of the first resource on the ith symbol acquired in this step,

is the number of OFDM symbols contained in the PUSCH,

is to indicate the number of REs available for carrying the target uplink information on the PUSCH, K indicates the size of the uplink data load, l₀Is in PUSCH the firstThe symbol index of the first OFDM symbol after the DMRS symbol that does not carry PUSCH DMRS.

Optionally, the terminal may substitute the number of all REs used for transmitting PUSCH data in the nominal PUSCH 1 into the formula [ 1 ], and calculate the number of REs occupied by the target uplink information on the first independent time domain resource. Or, the terminal may also substitute the acquired number of REs remaining after the number of REs occupied by the DMRS and PTRS reference signals is removed from the nominal PUSCH 1 into a formula [ 1 ], and calculate the number of REs occupied by the target uplink information on the first independent time domain resource. This is not a limitation of the present application.

In a possible implementation manner, there may be two or more target time domain resources obtained as described above, and the terminal may select a nominal PUSCH corresponding to the earliest actual PUSCH satisfying the timing requirement from the target time domain resources, and perform the subsequent steps.

In addition, in the embodiment of the present application, the number of resources occupied by the target uplink information is calculated according to the first resource number based on the PUSCH before segment, and since the first resource number included in the PUSCH resource before segment is greater than the first resource number included in the PUSCH resource after segment, the problem that the code rate of the target uplink information may exceed the maximum code rate due to a relatively small number of the first resources available in the PUSCH resource during calculation multiplexing can be avoided, and the demodulation efficiency of the base station is improved.
