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 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 Protocol stack of a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Media Access Control (MAC) layer is set 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 PUCCH and PUSCH, and accordingly, the base station may receive data transmitted by the terminal in PUCCH and PUSCH. Taking the example that the PUCCH carries UCI information, after the base station sends PDSCH data to the 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-acknowledgement (NACK) feedback through the 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 channel carrying the UCI information collides with the PUSCH, 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 resource actually adopted by the terminal in the PUSCH may be different from the resource configured by the base station. For example, when a resource used for a certain time of repeated transmission in the resources configured by the base station crosses a slot boundary or collides with a DownLink (DL) symbol configured by the base station, the terminal needs to segment (segment) the repeatedly transmitted resource configured by the base station according to the slot boundary and the DL symbol and transmit the repeatedly transmitted resource using the segmented resources included in the PUSCH.

Here, we can refer to the PUSCH for repeated transmission configured by the base station as: a nominal repetition (nominal retransmission) transmission PUSCH, also known as nominal PUSCH. The terminal segments a nominal PUSCH allocated by the base station, and then transmits a plurality of obtained PUSCHs, where a repeated transmission PUSCH at this time may be referred to as an actual repetition (actual retransmission) transmission PUSCH or an actual PUSCH.

Please refer to fig. 2, which illustrates a schematic structural diagram of resources 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 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 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 resources included in the actual PUSCH 204.

At present, there is no perfect solution for how a terminal performs data transmission when a channel carrying UCI collides with an actual PUSCH. In a possible implementation manner, the terminal may determine whether a channel carrying the UCI and a nominal PUSCH collide, and multiplex transmission of the UCI on an actual PUSCH when the collision occurs. The terminal compares the channel carrying the UCI with a nominal PUSCH configured by the base station, and if the channel carrying the UCI and the nominal PUSCH conflict with each other, the terminal can multiplex the UCI in the PUCCH to the actual PUSCH for transmission. When the terminal judges whether the PUCCH and the PUSCH carrying the UCI conflict or not, the PUCCH and the PUSCH are compared with a nominal PUSCH configured by the base station, when the nominal PUSCH configured by the base station needs to be segmented, if the nominal PUSCH configured by the base station is after the segment, the code rate of the UCI with smaller resource quantity which can be used for carrying the UCI in the actual PUSCH during multiplexing possibly exceeds the maximum code rate, so that the base station cannot demodulate correctly, the acceptance rate of the base station is low when the UCI is multiplexed on the actual PUSCH for transmission, 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, when the first channel and the third channel are overlapped and the first channel meets the first condition, multiplexing transmission is performed on the uplink data and the uplink control information on the first channel. The resource of the first channel is a part of the resource of the second channel, the second channel is a channel for carrying uplink data, and the third channel is a channel for transmitting uplink control information.

The second channel is a channel configured by the network device to the terminal for carrying uplink data, for example, the second channel is the nominal PUSCH shown in fig. 2, and the uplink data may be data carried in the PUSCH. The resources of the first channel are partial resources determined from the resources of the second channel, for example, the first channel is the actual PUSCH shown in fig. 2. After receiving the nominal PUSCH, the terminal may segment the nominal PUSCH in the manner shown in fig. 2, so as to identify each OFDM symbol corresponding to the actual PUSCH in each OFDM symbol corresponding to the nominal PUSCH, and thus identify the resource of the first channel from the resource of the second channel.

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

Optionally, the third channel is a channel configured by the network device to the terminal for carrying uplink control information, for example, the third channel is the PUCCH channel shown in fig. 2, and the uplink control information may be UCI carried in the PUCCH. The network device may configure the PUCCH to the terminal, and the terminal may transmit the uplink control information in the PUCCH configured by the network device after obtaining the PUCCH configured by the network device. The resource of the third channel may be a resource used when the uplink control information is transmitted this time, and may also be a resource formed by each OFDM symbol used when the uplink control information is transmitted this time.

Optionally, channels adopted by the terminal when transmitting the uplink control information and the uplink data may overlap, that is, the third channel and the first channel may overlap, causing a collision between the channels, and if the first channel satisfies the first condition, the terminal may multiplex and transmit the uplink control information on the first channel together with the uplink data. That is, in the first channel and the second channel that overlap, when the first channel satisfies the first condition, the terminal may multiplex uplink data and uplink control information on the first channel.

Optionally, the first channel and the third channel overlap, which may be understood as that the resource of the first channel overlaps with the resource of the second channel, or that the resource of the first channel overlaps with the OFDM symbol included in the resource of the second channel.

Referring to fig. 4, a diagram illustrating a channel collision according to an exemplary embodiment of the present application is shown. As shown in fig. 4, a first channel 401, a second channel 402, a third channel 403, and a fourth channel 404 are included. The first channel 401 and the second channel 402 are overlapped, and the third channel 403 and the fourth channel 404 are overlapped. That is, in the present application, collision and overlap have the same meaning.

In the embodiment of the application, when the first channel and the third channel are overlapped, whether the first channel meets the first condition is judged, so that whether the uplink data and the uplink control information are multiplexed and transmitted on the first channel is determined, wherein the resource of the first channel is part of the resource of the second channel, the problem that the code rate is too high when the uplink control information is multiplexed and transmitted in the first channel due to the fact that the number of the resource in the first channel is too small is solved, the accuracy rate of the network equipment for demodulating the uplink control information is improved, and the reliability of information transmission between the terminal and the network equipment is improved.

Optionally, the first condition includes:

a channel with the earliest starting time in a plurality of channels meeting the multiplexing timing requirement and overlapped with a third channel;

and/or;

the first number is greater than or equal to a target number, and the first number is used for indicating the number of resources used for transmitting uplink data in the first channel, or the number of all resources except the reference signal or part of resources in the first channel.

Optionally, the target number is obtained according to the number of resources of the second channel, or is obtained according to the number of resources of the first channel.

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

Optionally, the reference signal includes at least one of a demodulation reference signal DMRS or a phase tracking reference signal PTRS. Optionally, the method further includes:

when the first channel and the third channel are overlapped and the first channel does not meet the first condition, not sending the first channel; or,

when the first channel and the third channel are overlapped and the first channel does not meet the first condition, only the third channel is sent; or,

when the first channel and the third channel are overlapped and the first channel does not meet the first condition, not sending uplink control information; or,

when the first channel and the third channel are overlapped and the first channel does not meet the first condition, only transmitting uplink data in the first channel; or,

when the first channel and the third channel are overlapped and the first channel does not meet the first condition, sending uplink data in the first channel and transmitting uplink control information on a fourth channel, wherein the fourth channel is not overlapped with the first channel; or,

and when the first channel and the third channel are overlapped and the first channel does not meet the first condition, transmitting uplink data in the first channel and transmitting uplink control information in the third channel.

Optionally, the resource of the first channel is obtained by cutting the resource of the second channel.

Optionally, the first channel is an actual PUSCH, and the second channel is a nominal PUSCH.

Optionally, the uplink control information includes:

a PUCCH carrying acknowledgement ACK/negative acknowledgement NACK for PDSCH feedback,

or,

a PUCCH for carrying an uplink scheduling request SR corresponding to the PUSCH,

or,

PUCCH or PUSCH carrying channel state information 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 terminal may calculate a target number, and determine whether the first channel satisfies the first condition by using the target number. The target number is the number of resources required for multiplexing the uplink control information in the first channel. The scheme shown in fig. 3 above will be described by way of example, taking as an example one of the data whose target amount is in the first condition.

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 second channel configured by a network device, where the second channel is used for carrying a channel of uplink data.

The network device may send a resource that can be used by the terminal in the PUSCH to the terminal through Downlink Control Information (DCI), and accordingly, the terminal may demodulate Information in the DCI to obtain a nominal PUSCH (second channel).

Step 502, according to the fixed resource information, acquiring the resource of the first channel from the resource of the second channel.

The fixed resource information includes a time slot boundary, uplink and downlink configuration, and resource information indicated by unavailable resources.

Wherein the second channel configured to the terminal by the network device does not represent that all resources in the second channel are available to the terminal. For example, the network device needs to transmit some uplink and Downlink configurations (e.g., Downlink (DL) symbols, etc.) in some of these resources, and needs to occupy some of the resources, so that when the terminal actually uses the resources of the second channel, the unused resources are also selected for use. Or, the network device needs to transmit some unavailable resources (e.g., system data, etc.) in part of the resources of the second channel, and also needs to occupy part of the resources, so that when the terminal actually uses the resources of the second channel, the terminal also selects the unused resources to use.

The terminal may select resources available for PUSCH transmission from resources of a nominal PUSCH configured by the network device, where the resources available for PUSCH transmission are resources of an actual PUSCH determined by the terminal.

Referring to fig. 6, a schematic diagram of a resource structure of a channel according to an exemplary embodiment of the present application is shown, as shown in fig. 6, which includes a first time slot 601, a second time slot 602, and a third time slot 603. 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 1 st OFDM symbol corresponding to the 12 th to third slots 601 to 603 is the resource of the nominal PUSCH configured by the network device.

In the resources of the nominal PUSCH, 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 resources having the DL symbol, so the repeatedly transmitted resources actually used by the terminal do 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, the 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 resources included in the actual PUSCH 605. Here, the resources of the first channel are all 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). Optionally, each partition line included in the actual PUSCH 605 may also constitute one channel, for example, the resource of one channel in the first channel is: the OFDM symbols numbered 11-13 in the first slot 601; the resources of the other of the first channels are: the OFDM symbol numbered 0-2 in the second slot 602. By analogy, the OFDM symbols numbered 3-7 in the second slot 602 may also be a resource of one of the first channels; the OFDM symbols numbered 11-13 in the second slot 602 may also be a resource of one of the first channels; the OFDM symbol numbered 0 in the third slot 603 may also be a resource of one of the first channels.

And 503, when the first channel and the third channel are overlapped and the first channel meets the first condition, multiplexing and transmitting the uplink data and the uplink control information on the first channel.

The third channel is a channel for transmitting uplink control information. For example, the third channel is a PUCCH configured by the network device to the terminal. The terminal may determine whether the first channel and the third channel overlap. The method for the terminal to determine the channel overlap may refer to the method shown in fig. 4, which is not described herein again.

Optionally, the uplink control Information may also include a PUCCH carrying an acknowledgement ACK/negative acknowledgement 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).

When the first channel and the third channel overlap, the terminal may determine whether the first channel satisfies the first condition, and perform multiplexing transmission on the uplink data and the uplink control information on the first channel when the first channel satisfies the first condition.

Optionally, the first condition may be as follows: a channel with the earliest starting time in a plurality of channels meeting multiplexing timing requirements, which are overlapped with the third channel; and/or; the first number is greater than or equal to a target number, and the first number is used for indicating the number of resources used for transmitting uplink data in the first channel, or the number of all resources except the reference signal or part of resources in the first channel.

For example, in fig. 6, the resources of the channel in which the first channel and the third channel overlap are symbol 11 to symbol 13, and the terminal may determine whether the channel can satisfy the multiplexing timing requirement. And/or the terminal acquires the first quantity, calculates the target quantity and judges the size relation between the first quantity and the target quantity. When the channel meets the multiplexing timing requirement and the first number is greater than or equal to the target number, the first channel is considered to meet a first condition.

The first number is used to indicate the number of resources used for transmitting uplink data in the first channel, or the number of all resources except for the reference signal or a part of resources in the first channel. The target number is derived from the number of resources of the second channel, or alternatively, from the number of resources of the first channel.

Optionally, the Resource amount here may be the amount of any one of Resource Elements (REs), subcarriers, and OFDM symbols. For example, the terminal may calculate the number of REs (i.e., the target number) required for multiplexing the uplink control information on the first channel according to the number of REs in the second channel. Or, the terminal may calculate the number of subcarriers required for multiplexing the uplink control information on the first channel according to the number of subcarriers in the second channel. Or, the terminal may calculate the number of OFDM symbols required for multiplexing the uplink control information on the first channel according to the number of OFDM symbols in the second channel. This is not limited by the examples of the present application.

Alternatively, the Reference Signal here may include at least one of a Demodulation Reference Signal (DMRS) and a Phase Tracking Reference Signal (PTRS).

Optionally, when the terminal determines whether the channel meets the multiplexing timing requirement, the specification in NR Rel-15 may be followed, which is not limited in this embodiment.

Referring to fig. 7, a schematic diagram of an exemplary embodiment of the present application relating to overlapping of the first channel and the third channel of fig. 6 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. The terminal may obtain that the resource of the overlapped channel of the first channel and the third channel includes the OFDM symbol numbered 11 in the first slot 701 to numbered 2 in the second slot 702 through the above steps. The overlapped channels may include an actual PUSCH 1 and an actual PUSCH 2, and at this time, the terminal may determine whether the actual PUSCH 1 meets the multiplexing timing requirement. And/or the terminal acquires the first quantity, calculates the target quantity and judges the size relation between the first quantity and the target quantity. And when the actual PUSCH 1 meets the multiplexing timing requirement and the first number is greater than or equal to the target number, the first channel is considered to meet a first condition. Optionally, the obtaining manner of the first number and the target number is similar to that described above, and is not described here again.

Optionally, when the first channel overlaps with the third channel and the first channel does not satisfy the first condition, the first channel is not sent; or only sending the third channel when the first channel and the third channel are overlapped and the first channel does not meet the first condition; or when the first channel and the third channel are overlapped and the first channel does not meet the first condition, not sending the uplink control information; or, when the first channel and the third channel are overlapped and the first channel does not meet the first condition, only transmitting uplink data in the first channel; or when the first channel and the third channel are overlapped and the first channel does not meet the first condition, sending uplink data in the first channel and transmitting uplink control information on a fourth channel, wherein the fourth channel is not overlapped with the first channel; or, when the first channel and the third channel are overlapped and the first channel does not meet the first condition, transmitting the uplink data in the first channel and transmitting the uplink control information in the third channel. Optionally, the above-mentioned not sending the first channel may be understood as not sending data carried in the first channel, and sending the third channel may be understood as sending data carried in the third channel.

For example, in fig. 6, when the first channel and the third channel overlap and the first channel does not satisfy the first condition, the terminal does not transmit the actual PUSCH 1; or when the first channel and the third channel are overlapped and the first channel does not meet the first condition, the terminal only sends the PUCCH; or when the first channel and the third channel are overlapped and the first channel does not meet the first condition, the terminal does not send the uplink control information; or when the first channel and the third channel are overlapped and the first channel does not meet the first condition, the terminal only transmits uplink data in the actual PUSCH 1; or, when the first channel and the third channel are overlapped and the first channel does not meet the first condition, the terminal sends uplink data in the actual PUSCH 1 and transmits uplink control information on the actual PUSCH 2; or, when the first channel and the third channel are overlapped and the first channel does not satisfy the first condition, the terminal transmits uplink data in the actual PUSCH 1 and transmits uplink control information in the PUCCH.

For another example, in fig. 7, when the first channel overlaps with the third channel and the first channel does not satisfy the first condition, the terminal does not transmit the actual PUSCH 1; or when the first channel and the third channel are overlapped and the first channel does not meet the first condition, the terminal only sends the PUCCH; or when the first channel and the third channel are overlapped and the first channel does not meet the first condition, the terminal does not send the uplink control information; or, when the first channel and the third channel are overlapped and the first channel does not meet the first condition, the terminal only transmits uplink data in the actual PUSCH 1; or, when the first channel and the third channel are overlapped and the first channel does not meet the first condition, the terminal sends uplink data in the actual PUSCH 1 and transmits uplink control information on the actual PUSCH 3; or, when the first channel and the third channel are overlapped and the first channel does not satisfy the first condition, the terminal transmits uplink data in the actual PUSCH 1 and transmits uplink control information in the PUCCH.

In the embodiment of the present application, when the first channel overlaps with the third channel, by determining whether the first channel satisfies the first condition, thereby deciding whether to multiplex transmission of the uplink data and the uplink control information on the first channel, wherein the resources of the first channel are partial resources in the resources of the second channel, the calculation of the corresponding target quantity is to calculate the resource quantity required by the target uplink information according to the resource quantity in the PUSCH before the segment, because the resource quantity contained in the resource of the PUSCH before segment is more than the resource quantity contained in the resource of the PUSCH after segment, the problem of overlarge code rate of uplink control information in multiplexing transmission in the first channel due to the fact that the resource quantity in the first channel is too small is solved, the accuracy of the network equipment for demodulating the uplink control information is improved, and the reliability of information transmission between the terminal and the network equipment is improved.
