For easy understanding, the application scenario related to the present application will be briefly described below.

Referring to fig. 1, a schematic 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: a number of terminals 110 and a base station 120.

Where terminal 110 may be a device that provides voice and/or data connectivity to a user. Terminal 110 may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), and terminal 110 may be an internet of things terminal such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an internet of things terminal, for example, a fixed, portable, pocket, hand-held, computer-built-in, or vehicle-mounted device. Such as a Station (STA), subscriber Unit (Subscriber Unit), subscriber Station (Subscriber Station), mobile Station (Mobile Station), mobile Station (Mobile), remote Station (Remote Station), access point, remote Terminal (Remote Terminal), access Terminal (Access Terminal), user Equipment (User Terminal), user Agent (User Agent), user Equipment (User Device), or User Equipment (UE). Alternatively, the terminal 110 may be an unmanned aerial vehicle device, an in-vehicle 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, also called New Radio (NR) system. Alternatively, the wireless communication system may be a next generation system of the 5G system.

Alternatively, the base station 120 may be a base station (gNB) in a centralized and distributed architecture in a 5G system. When the base station 120 adopts a centralized and Distributed architecture, it generally includes a Centralized Unit (CU) and at least two Distributed Units (DUs). A protocol stack of a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a medium access control (Media Access Control, MAC) layer is provided in the centralized unit; a Physical (PHY) layer protocol stack is disposed in the distribution unit, and the specific implementation of the base station 120 is not limited in this embodiment of the present application.

A wireless connection may be established between base station 120 and terminal 110 over a wireless air interface. In various embodiments, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, such as the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G-based technology standard of a next generation mobile communication network.

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 device 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 (Mobility Management Entity, MME) in an evolved packet core network (Evolved Packet Core, EPC). Alternatively, the network management device may be other core network devices, such as a Serving GateWay (SGW), a public data network GateWay (Public Data Network GateWay, PGW), a policy and charging rules function (Policy and Charging Rules Function, PCRF) or a home subscriber server (Home Subscriber Server, HSS), etc. The embodiment of the present application is not limited to the implementation form of the network management device 130.

In the above-described wireless communication scenario shown in fig. 1, when the terminal transmits data to the base station, the base station may receive the data transmitted by the terminal in the PUCCH and PUSCH by transmitting the corresponding data in the PUCCH and PUSCH. Taking UCI information carried in PUCCH as an example, after the base station transmits PDSCH data to the terminal through a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), the terminal needs to feed back whether the PDSCH data transmitted by the base station is received correctly, where the terminal may feed back through Acknowledgement (ACK) or Negative Acknowledgement (NACK) through PUCCH. Alternatively, the base station may instruct the terminal to perform periodic or quasi-periodic channel state information (Channel State Information, CSI) measurements, and the terminal needs to feed back CSI measurement results to the base station through the PUCCH. The information of the fed back ACK, NACK, or CSI measurement result may be referred to as UCI information. When the time domain resource of the PUCCH of the UCI information sent by the terminal conflicts with the time domain resource occupied by the PUSCH indicated by the base station, the terminal can multiplex the UCI information on the PUSCH for transmission.

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

When the terminal performs repeated transmission in the PUSCH, there may be a difference between the time domain resource actually adopted by the terminal in the PUSCH and the time domain resource configured by the base station. For example, when there is a time domain resource adopted by a certain repeated transmission in the time domain resources configured by the base station and there is a DownLink Data (DL) symbol that crosses a slot boundary or collides with the DownLink Data (DL) symbol configured by the base station, the terminal needs to divide (segment) the time domain resources configured by the base station according to the slot boundary and the DL symbol, and uses the time domain resources included in the PUSCH after division for transmission.

Here, we can refer to the time domain resource of the repeated transmission PUSCH configured by the base station as: the time domain resource of the nominal repetition (nominal repetition) transmission is also referred to as nominal PUSCH (nominal PUSCH). After the terminal segments the time domain resource of the nominal repeated transmission allocated by the base station, the obtained multiple PUSCHs are transmitted, and the repeated transmission at this time can be called actual repeated (actual repetition) transmission, and the time domain resource of the actual repeated transmission can be called an actual PUSCH (actual PUSCH).

Referring to fig. 2, a schematic structural diagram of a PUSCH including time domain resource according to an exemplary embodiment of the present application is shown. As shown in fig. 2, the first slot 201, the second slot 202, the nominal PUSCH 203, and the actual PUSCH 204 are included. 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, the length of each transmission is 6, when the terminal obtains the repeated transmissions of the PUSCH configured by the base station, that is, the nominal PUSCH 203 (including the nominal PUSCH 1, the nominal PUSCH 2 and the nominal PUSCH 3) is obtained, the terminal may segment the nominal PUSCH 203 according to the time domain resource condition 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 cases. When the terminal transmits PUSCH data, transmission may be performed according to time domain resources contained in the actual PUSCH 204.

At present, when the time domain resources adopted for the data transmission collide, how the terminal performs the data transmission does not have a perfect solution at present. In a possible implementation manner, when the terminal determines whether the PUCCH carrying UCI and PUSCH are in collision or not, the terminal compares the time domain resources occupied by the PUCCH carrying UCI and the nominal PUSCH configured by the base station according to each time domain resource, and if the two time domain resources are in collision, the terminal can multiplex UCI in the PUCCH onto PUSCH for transmission. When the nominal PUSCH configured by the base station needs to be segmented, if the nominal PUSCH configured by the base station occupies smaller time domain resources after segmented, the actual PUSCH obtained after segmented does not collide with the PUCCH, so that the time domain resources are erroneously selected when the PUCCH is multiplexed on the PUSCH for transmission, and the reliability of information transmission between the terminal and the base station is reduced.

In order to provide a better method for multiplexing UCI in PUSCH for transmission by a terminal and improve reliability of information transmission, the embodiment of the present application provides a solution, which can reduce error rate of PUSCH transmission while multiplexing UCI in 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, and 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 steps of:

step 301, acquiring a first time domain resource, where the first time domain resource is a time domain resource determined by a terminal from time domain resources of a repeated PUSCH configured by a network device.

Optionally, the first time domain resource may also be referred to as an actual repeatedly transmitted time domain resource, where the time domain resource of the repeatedly transmitted PUSCH configured by the network device may also be referred to as a nominal repeatedly transmitted time domain resource, that is, the actual repeatedly transmitted time domain resource is a real PUSCH time domain resource, the nominal repeatedly transmitted time domain resource is a nominal PUSCH, and after the terminal receives the nominal PUSCH, the terminal may segment the nominal PUSCH in the manner of fig. 2, so as to confirm each OFDM symbol corresponding to the real PUSCH in each OFDM symbol corresponding to the nominal PUSCH.

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

Step 302, a second time domain resource is acquired, where the second time domain resource is a time domain resource configured by the network device to the terminal for carrying the target uplink information in the physical uplink control channel PUCCH.

The network device may configure the PUCCH to the terminal, and after the terminal obtains the PUCCH configured by the network device, the terminal may transmit the target uplink information in the PUCCH configured by the network device. The second time domain resource may be a time domain resource adopted when the target uplink information is transmitted at this time, and also be a time domain resource formed by each OFDM symbol adopted when the target uplink information is transmitted at this time, where the target uplink information may refer to information carried in the PUCCH at 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 take the acquired time domain resource of the PUCCH as the second time domain resource.

In step 303, when the first time domain resource collides with the second time domain resource, multiplexing and transmitting the PUSCH and the target uplink information on the first time domain resource.

The time domain resources adopted by the terminal when transmitting the PUSCH and the PUCCH may overlap, causing collision between the PUSCH and the PUCCH, and at this time, the terminal may multiplex and transmit the target uplink information together with the PUSCH on the first time domain resource. The collision between the first time domain resource and the second time domain resource may mean that OFDM symbols included in each of the first time domain resource and the second time domain resource overlap.

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

In the embodiment of the application, the terminal acquires the time domain resource of the actual repeated transmission in the PUSCH, and the network equipment is configured to the time domain resource of the terminal for bearing the target uplink information in the PUCCH, and when the two conflict, the multiplexing transmission is performed on the target uplink information on the acquired time domain resource of the actual repeated transmission in the PUSCH. Therefore, the terminal in the application judges whether the time domain resources corresponding to the actual PUSCH collide with the PUCCH according to the time domain resources corresponding to the actual PUSCH after the segment, and selects the time domain resources corresponding to the actual PUSCH which collide to multiplex, so that the problem of wrong time domain resource selection caused by larger time domain resources occupied by the actual PUSCH before the segment is avoided, 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 PUSCH;

when the first time domain resource collides with the second time domain resource, multiplexing and transmitting the PUSCH and the target uplink information on the first time domain resource comprises the following steps:

when the first time domain resource conflicts with the second time domain resource, a third time domain resource is obtained, wherein the third time domain resource comprises the time domain resource for independently transmitting the PUSCH, where the time domain resource where the first time domain resource conflicts with the second time domain resource is located;

and when the PUCCH and the PUSCH in the third time domain resource meet the multiplexing time sequence requirement, multiplexing and transmitting 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 PUSCH, when the PUCCH and PUSCH in the third time domain resource meet the multiplexing timing requirement, multiplexing PUSCH and target uplink information on the third time domain resource, including:

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

Optionally, multiplexing transmission is performed on PUSCH and target uplink information on the first time domain resource, including:

Calculating a target quantity according to the quantity of first resources in time domain resources for repeatedly transmitting the PUSCH configured by the network equipment, wherein the target quantity is the quantity of first resources occupied in the first time domain resources when the target uplink information multiplexes and transmits the PUSCH and the target uplink information on the first time domain resources;

and when multiplexing and transmitting 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 first resources in the time domain resources of the repeated PUSCH configured by the network device, includes:

acquiring a target time domain resource in the time domain resources of the repeated transmission PUSCH configured by the network equipment, wherein the target time domain resource is the time domain resource of the repeated transmission configured by the network equipment corresponding to the transmission resource of the conflict between the first time domain resource and the second time domain resource;

calculating the target quantity according to the quantity 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 the PUSCH data in the target time domain resource; or the number of the first resources is the number of the first resources remained 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 resource of a time-frequency resource element RE, a subcarrier, and an OFDM symbol.

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

Optionally, the method further comprises:

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

acquiring a first time domain resource, including:

and acquiring the first time domain resource from the repeated transmission 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 resources.

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

All the above optional technical solutions may be combined according to any choice to form an optional embodiment of the present application, which is not described in detail herein.

In one possible implementation manner, the first time domain resource may further include a time domain resource for independently transmitting 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 the time domain resource for independently transmitting PUSCH.

Referring to fig. 5, a flowchart of a method of another information transmission method according to an exemplary embodiment of the present application is shown, and 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 steps of:

in step 501, a time domain resource configured by a network device for repeated PUSCH transmission is received.

The network device may send the time domain resource that can be used by the terminal in the PUSCH to the terminal through downlink control information (Downlink Control Information, DCI), and correspondingly, the terminal may demodulate the information in the DCI to obtain the time domain resource of the PUSCH that is transmitted in a nominal repetition mode.

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

Wherein the time domain resources configured by the network device to the terminal do not represent all of the time domain resources available to the terminal. For example, the network device needs to transmit some uplink and Downlink configuration (such as Downlink (DL) symbols) on some of these time domain resources, and needs to occupy some of these time domain resources, so that when the terminal actually uses the time domain resources configured by the network device to the terminal, the terminal also selects the unused time domain resources for use. Or, the network device needs to transmit some unavailable resources (such as system data, etc.) in some of these time domain resources, and also needs to occupy some of these time domain resources, so that when the terminal actually uses the time domain resources configured by the network device to the terminal, the terminal also selects the unused time domain resources for use.

The terminal can select time domain resources available for PUSCH transmission from time domain resources of nominal repeated transmission configured by the network device, wherein the time domain resources available for PUSCH transmission are the time domain resources of actual repeated transmission determined by the terminal, and correspondingly, the terminal can acquire the time domain resources of actual repeated transmission determined by the terminal (namely, the first time domain resources). The first time domain resource may include an independent time domain resource.

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

In the time domain resource of the nominal retransmission, the network device has DL symbols in the 8 th to 10 th OFDM symbols in the second slot 602, and the terminal cannot transmit PUSCH in the time domain resource with DL symbols, so the time domain resource of the retransmission actually used by the terminal does not include the 8 th to 10 th OFDM symbols in the second slot 602. In addition, since the PUSCH transmission is not available at the slot boundary, the terminal needs to re-segment the nominal PUSCH 504 when the PUSCH transmission is actually performed.

After the terminal re-segments the nominal PUSCH 604, an actual PUSCH 605 as contained in fig. 6 may be obtained, and when the terminal actually transmits the PUSCH, the terminal may transmit by using a time domain resource contained in the actual PUSCH 605. Wherein the first time domain resource is all 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 accordingly, 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: 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 acquire the first time domain resource, or may acquire each independent time domain resource in the first time domain resource.

In step 503, a second time domain resource is obtained, where the second time domain resource is configured by the network device to the terminal to be used for carrying the target uplink information in the physical uplink control channel PUCCH.

The manner of acquiring 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 described herein.

Optionally, the target uplink information may also include a PUCCH carrying a positive acknowledgement ACK/negative acknowledgement NACK for PDSCH feedback, or a PUCCH carrying an uplink scheduling request (Scheduling Request, SR) corresponding to PUSCH, or any one of PUCCH and PUSCH carrying channel state information (Channel State Information, CSI).

In step 504, when the first time domain resource collides with the second time domain resource, a third time domain resource is acquired.

The third time domain resource comprises a time domain resource for independently transmitting the PUSCH channel, where the time domain resource where the first time domain resource collides with the second time domain resource is located. Alternatively, the third time domain resource may be an independent time domain resource including a fourth time domain resource in each independent time domain resource, where the fourth time domain resource is a time domain resource where the first time domain resource collides with the second time domain resource.

The terminal may acquire a time domain resource in which the first time domain resource collides with the second time domain resource, and acquire a time domain resource (i.e., a third time domain resource) including the time domain resource in the first time domain resource according to the time domain resource. As shown in fig. 6, the second time domain resource 606 corresponding to the PUCCH is further included, where the second time domain resource 606 collides with the first time domain resource. Optionally, the terminal may determine whether the first time domain resource and the second time domain resource collide, and if so, may acquire 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 formed by OFDM symbols numbered 11-13 in the first time slot, where 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 11-13 in the first time slot. Optionally, if the time domain resource where the first time domain resource and the second time domain resource collide is a time domain resource formed by 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.

In step 505, when the PUCCH and 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 a time sequence relation between the PUCCH and the PUSCH in the third time domain resource, judge whether the time sequence relation between the PUCCH and the PUSCH in the third time domain resource meets the multiplexing time sequence 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 time sequence requirement, and 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 time sequence requirement. Alternatively, when the terminal determines whether the timing relationship between the overlapped PUCCH and PUSCH meets the multiplexing timing requirement, the embodiment of the present application is not limited to this, and may be defined in NR Rel-15.

In one 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 judges that the two independent time domain resources both meet the multiplexing time sequence requirement, the terminal can sequentially perform multiplexing transmission on 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 a certain independent time domain resource meets the multiplexing timing requirement, the terminal may perform multiplexing transmission on the PUSCH and the target uplink information on the independent time domain resource.

Referring to fig. 7, a schematic diagram of another PUCCH and PUSCH coincidence of fig. 6 according to an exemplary embodiment of the present application is shown. As shown in fig. 7, a first time slot 701, a second time slot 702, and a third time slot 703 are included. Nominal PUSCH 704, actual PUSCH 705, second time domain resource 706, third time domain resource 707, first independent time domain resource 708, second independent time domain resource 709. The terminal may acquire that the third time domain resource 707 is a time domain resource including OFDM symbols numbered 11 in the first slot 701 to number 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 (time domain resource of the OFDM symbol numbered 11-13 in the first time slot 701), a second independent time domain resource (time domain resource of the OFDM symbol numbered 0-2 in the second time slot 702), and the terminal may determine a timing relationship between the PUCCH and the PUSCH in the first independent time domain resource and a timing relationship between the PUCCH and the PUSCH in the second independent time domain resource, where, if the terminal determines the first independent time domain resource and the second independent time domain resource, the timing relationship between the PUCCH and the PUSCH in the first independent time domain resource 708 satisfies the multiplexing timing requirement; the timing relationship of PUCCH and PUSCH in the second independent time domain resource 709 also satisfies the multiplexing timing requirement; at this time, the terminal may select the first independent time domain resource 708 with the first order for multiplexing transmission, that is, multiplex transmission is performed on the PUSCH and the target uplink information on the first independent time domain resource 708.

Optionally, when the terminal multiplexes PUSCH and the target uplink information in a certain time domain resource, the number of resources occupied by the target uplink information in the time domain resource needs to be calculated, and the target uplink information is transmitted on the time domain resource according to the calculated number of resources.

For example, if the terminal performs multiplexing transmission on 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 first resources in the time domain resource that is nominally repeated for transmission, where the target number is the number of first resources occupied in the first time domain resource when the target uplink information performs multiplexing transmission on 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, according to the number of REs in the time domain resource of the nominal repeated transmission, the number of REs occupied by the target uplink information on the first time domain resource. Or, the terminal may calculate, according to the number of subcarriers in the time domain resource of the nominal repeated transmission, the number of subcarriers occupied by the target uplink information on the first time domain resource. Or, the terminal may calculate, according to the number of OFDM symbols in the time domain resource of the nominal repeated transmission, the number of OFDM symbols occupied by the target uplink information on the first time domain resource. The embodiments of the present application are not limited in this regard.

In one possible implementation, the terminal may perform the calculation in the following manner when calculating the target number. The terminal may obtain a target time domain resource in the time domain resources of the nominal repeated transmission configured by the network device. The target time domain resource is a nominal repeatedly transmitted time domain resource corresponding to an actual transmission resource where the first time domain resource collides with the second time domain resource. And the terminal calculates the target quantity according to the quantity of the first resources in the target time domain resources. Optionally, the number of 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 remained after subtracting the number of the first resources occupied by the second resources from the target time domain resources. And finally, the terminal can multiplex and transmit the PUSCH and the target uplink information on the first time domain resource according to the number of the second resources. Alternatively, the second resources herein may include at least one of demodulation reference signals (Demodulation Reference Signal, DMRS) or phase tracking reference signals (Phase Tracking Reference Signal, PTRS), etc.

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 multiplexes and transmits 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 and the number of resources occupied by the target uplink information in the first independent time domain resource can be calculated.

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

Optionally, the terminal acquires 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 can calculate the target number Q with reference to the formula [ 1 ] _ACK 。

Wherein O is _ACK Is the number of HARQ-ACK (Hybrid Automatic Repeat request-ACK, hybrid automatic repeat request positive acknowledgement) bits, L _ACK Is the number of CRC bits, beta _offset Is a code rate compensation factor, alpha is a parameter of upper limit for limiting the number of second resources, M _SC (l) Is the number of the first resources on the first symbol acquired in this step,is the number of OFDM symbols contained in PUSCH, +.>The number of REs on the PUSCH, which can be used for bearing the uplink information of the target, K represents the load size of uplink data, and l ₀ Is the symbol index of the first OFDM symbol that does not carry PUSCH DMRS after the first DMRS symbol in PUSCH.

Optionally, the terminal may bring the number of REs obtained for transmitting PUSCH data in the nominal PUSCH 1 into 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 bring the number of REs remaining after removing the number of REs occupied by the DMRS and PTRS reference signals in the obtained 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. The present application is not limited in this regard.

In one possible implementation manner, there may be two or more obtained target time domain resources, and the terminal may select a nominal PUSCH corresponding to the earliest practical PUSCH including the target PUSCH satisfying the timing requirement from the target time domain resources and execute the subsequent steps.

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