Description

Control information transmission method and terminal equipment

Technical Field

The embodiment of the application relates to a communication technology, and in particular relates to a control information transmission method and terminal equipment.

Background

In a future 5G communication system, a terminal device may send uplink data to a network device based on a time-frequency resource dynamically scheduled or semi-statically scheduled by the network device. A Channel in which the terminal device transmits an Uplink Shared Channel (UL-SCH) and/or Uplink Control Information (UCI) to the network device is referred to as a Physical Uplink Shared Channel (PUSCH). When the network equipment adopts a dynamic mode to schedule and send time-frequency resources of the PUSCH for the terminal equipment, the terminal equipment needs to send a scheduling request to the network equipment when uplink data transmission exists. After receiving the scheduling request, the network device allocates a time-frequency resource for sending the PUSCH to the terminal device, and indicates the allocated time-frequency resource for sending the PUSCH to the terminal device through the control signaling, so that the terminal device can send the PUSCH to the network device on the time-frequency resource.

In order to support the above-mentioned technologies of dynamic scheduling, downlink Multiple Input Multiple Output (MIMO) transmission, hybrid automatic repeat request (harq), and the like, a terminal device needs to feed back Uplink Control Information (UCI) to a base station. The UCI may include at least one of a Scheduling Request (SR), Channel State Information (CSI), Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK), and the like. The HARQ-ACK may include at least one of Acknowledgement (ACK), Negative Acknowledgement (NACK), and Discontinuous Transmission (DTX). The CSI may include at least one of a Channel Quality Indicator (CQI), beam setting information, a Rank Indicator (RI), a Precoding Matrix Indicator (PMI), and the like.

However, in the 5G communication system, how the terminal device transmits the UCI on the PUSCH is an issue to be solved urgently.

Detailed Description

In a future 5G communication system, a terminal device can transmit PUSCH to a network device based on time-frequency resources for transmitting PUSCH dynamically scheduled or semi-statically scheduled by the network device. When the network equipment adopts a dynamic mode to schedule and send time-frequency resources of the PUSCH for the terminal equipment, the terminal equipment needs to send a scheduling request to the network equipment when uplink data transmission exists. After receiving the scheduling request, the network device allocates a time-frequency resource for sending the PUSCH to the terminal device, and indicates the allocated time-frequency resource for sending the PUSCH to the terminal device through the control signaling, so that the terminal device can send the PUSCH to the network device on the time-frequency resource.

The following describes the technical solutions of the embodiments of the present application in detail through some embodiments, taking the communication system as an example. The following several embodiments may be combined with each other and may not be described in detail in some embodiments for the same or similar concepts or processes.

Fig. 2 is a flowchart illustrating a method for transmitting control information according to an embodiment of the present disclosure. The present embodiment relates to a process of how a terminal device determines time-frequency resources for transmitting a control channel on time-frequency resources used when transmitting a data shared channel. As shown in fig. 2, the method may include:

s101, the terminal device determines a first time-frequency resource, wherein the first time-frequency resource is used for the terminal device to send a PUSCH to the network device.

Specifically, the PUSCH is used for a physical channel through which the terminal device transmits the UL-SCH and/or the UCI to the network device. Other features of the PUSCH are not limited in the embodiments of the present application. It will be understood by those skilled in the art that the above physical channels, UL-SCH and UCI may still follow the terminology of PUSCH, UL-SCH and UCI in a 5G mobile communication system, and that other terminology may be employed. Therefore, the embodiments of the present application do not limit the nomenclature of the PUSCH, UL-SCH, and UCI in each communication system. In the embodiments of the present application, PUSCH, UL-SCH, and UCI are taken as examples for explanation. The terminal device may transmit the UL-SCH and or UCI on the PUSCH.

In this embodiment, the terminal device may determine the first time-frequency resource according to scheduling information that is sent by the network device and used for indicating the first time-frequency resource. For example, the terminal device may determine a frequency location, a location in time, etc. of the first time-frequency resource in the supported uplink bandwidth. Optionally, the network device may carry the scheduling information in a downlink control channel (e.g., a physical downlink control channel) and send the scheduling information to the terminal device. Alternatively, the network device may carry the scheduling information in configuration information of other higher layers.

S102, the terminal device determines a second time frequency resource, wherein the second time frequency resource is used for the terminal device to send UCI to the network device, and the first time frequency resource comprises the second time frequency resource.

Wherein, the UCI may include at least one of HARQ-ACK and CSI. Wherein the CSI comprises at least one of: CQI, beam setting information, PMI, RI. And other time frequency resources in the first time frequency resource are used for the terminal equipment to send the UL-SCH of the uplink shared channel. The information carried in the UL-SCH includes uplink traffic data of the terminal device.

On one hand, the capability of the terminal device may not support the simultaneous transmission of the physical uplink control channel and the PUSCH; on the other hand, Intermodulation Interference (IMD) between signals transmitted on the physical uplink control channel and the PUSCH results in poor reception performance of the two channels. Therefore, the terminal device may determine a part of the time-frequency resources (second time-frequency resources) for transmitting UCI among the time-frequency resources for transmitting PUSCH, and the remaining time-frequency resources for transmitting UL-SCH. Or, the network device may also trigger the terminal device to send UCI on the PUSCH in a dynamic scheduling manner. That is to say, in this embodiment, the UCI may occupy a part of the time-frequency resources (i.e., the second time-frequency resources) in the first time-frequency resources for transmission. Therefore, after determining the first time-frequency resource, the terminal device may determine a second time-frequency resource for transmitting UCI from the first time-frequency resource. Optionally, when the UCI sent by the terminal device includes multiple types, the terminal device may determine, in the first time-frequency resource, a second time-frequency resource corresponding to each type of UCI.

And S103, the terminal equipment sends UCI to the network equipment through the second time-frequency resource.

Specifically, after determining the second time-frequency resource from the first time-frequency resource, the terminal device may send the UCI to the network device through the second time-frequency resource, and send the UL-SCH through the time-frequency resources other than the second time-frequency resource. In this way, UCI transmission on PUSCH can be implemented in a 5G communication system.

Correspondingly, when receiving the UCI, the network device may also determine a first time-frequency resource for the terminal device to transmit the PUSCH, and then determine a second time-frequency resource for transmitting the UCI, so that the network device may receive the UCI transmitted by the terminal device on the second time-frequency resource, and receive the UL-SCH transmitted by the terminal device on the time-frequency resources other than the second time-frequency resource.

In the method for transmitting control information provided in the embodiment of the present application, after determining the first time-frequency resource for transmitting the physical uplink channel, the terminal device may determine, from the first time-frequency resource, the second time-frequency resource for transmitting the uplink control information, so that the terminal device may transmit the uplink control information by using part or all of the time-frequency resources on the first time-frequency resource, thereby implementing transmission of the control information in the 5G communication system.

In the 5G communication system, to satisfy the pipelining processing procedure of uplink data, the DMRS is generally located at the top symbol in the PUSCH. Therefore, the terminal device may determine the second time-frequency resource for transmitting UCI based on the following factors. Specifically, the method comprises the following steps:

first, better channel estimation performance can be obtained since UCI is transmitted on symbols close to DMRS. Therefore, the resource on the symbol close to the DMRS may be considered as the second time-frequency resource, so as to ensure that the terminal device can improve the demodulation performance of the control information when transmitting UCI using the second time-frequency resource.

For example, the UCI may be, for example, a UCI including HARQ-ACK with higher reliability requirement and higher delay requirement. By using the resource on the symbol close to the DMRS as the second time-frequency resource, the HARQ-ACK can obtain the most accurate channel estimation, and meanwhile, the network equipment can obtain the UCI as soon as possible, so as to improve the overall time delay performance of the system. Illustratively, the terminal device feeds back the HARQ-ACK as early as possible, so that the network device processes subsequent downlink transmission as early as possible according to the feedback information of the HARQ-ACK, thereby shortening the delay of downlink transmission.

For example, to meet reliability under severe latency requirements, a technique of repeating transmission many times may be employed. And determining the number of times of retransmission and a modulation coding mode before sending the downlink data according to the quality of the downlink channel. For example, the reliability gain is obtained by repeating the transmission 4 times. Theoretically, in a white noise channel, a 3dB reliability improvement can be obtained for each repetition of data. The number of repetitions may be pre-configured or termination may be achieved by ACK feedback. However, if the same Modulation and Coding Scheme (MCS) is adopted for multiple repeated transmissions, the change of the channel quality over time cannot be dealt with, and the effect of the repeated transmissions on improving the reliability is reduced. Therefore, one channel state feedback method may be: and after receiving the retransmission (Repetition) data, the terminal equipment feeds back CSI to the network equipment. After receiving the CSI, the network device may adjust the MCS based on the CSI. Unlike the CSI periodically transmitted by the terminal device, the CSI may be a Low Latency CSI (LL-CSI). The LL-CSI is generated by the terminal device according to the demodulation reference signal corresponding to the downlink data after receiving the downlink data, and is channel quality information that can be quickly obtained and fed back without the terminal device performing data demodulation and decoding on the downlink data. The LL-CSI is triggered by the fact that terminal equipment receives downlink data, and is measured based on demodulation reference signals corresponding to the downlink data. The LL-CSI can be fed back to the network equipment before the terminal equipment demodulates and decodes the downlink data, so that the network equipment can conveniently and timely adjust the scheduling mode of the downlink data during subsequent repeated transmission or retransmission, and particularly for downlink ultra-reliable low-delay communication data, the LL-CSI can meet the requirements of low delay and high reliability of URLLC data. For example, LL-CSI may be an offset value of MCS with respect to MCS used by the terminal device before, or an offset value of CQI with respect to CQI reported by the terminal device before, etc. When the UCI is the UCI comprising the LL-CSI, the resources on the symbols close to the DMRS are used as the second time-frequency resources, so that the transmission of the LL-CSI can obtain the most accurate channel estimation, and meanwhile, the network equipment can obtain the LL-CSI as soon as possible, so that the scheduling information of downlink data transmission can be adjusted.

For example, the UCI may be, for example, a UCI including RI in CSI. Since the resources occupied by the UL-SCH transmitted in the PUSCH on the first time-frequency resources depend on how many resources are occupied by the CSI. That is, the resource occupied by the CSI is subtracted from the first time/frequency resource, and the remaining resource is the resource occupied by the UL-SCH in the PUSCH. Therefore, the network device needs to determine the resource for the UL-SCH in the first time-frequency resource according to the resource occupied by the CSI to decode the UL-SCH transmitted on the PUSCH. In addition, the bit number of the CQI/PMI in the CSI depends on the RI configured in a semi-static mode, and the bit number of the RI is determined in the semi-static mode by the terminal equipment. Therefore, the network device needs to detect the RI as early as possible to determine the bit number of the CQI/PMI and further determine the resource occupied by the UL-SCH, so as to demodulate the UL-SCH transmitted in the PUSCH. By using the resource on the symbol close to the DMRS as the second time-frequency resource and mapping the UCI to the resource on the symbol close to the DMRS, the network equipment can demodulate as early as possible to obtain the RI, thereby determining the bit number of the CQI/PMI, demodulating the UL-SCH transmitted on the PUSCH and improving the efficiency of data transmission. It should be noted that, since the HARQ-ACK is transmitted in a puncturing manner on the first time-frequency resource, the HARQ-ACK does not affect decoding of the UL-SCH transmitted in the PUSCH.

Secondly, the future 5G communication system supports two uplink signal waveforms, which are: a Single-carrier Frequency-Division Multiple Access (SC-FDMA) based waveform, and a Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) based waveform. When the waveform of SC-FDMA is adopted to send UCI, through the processing of some discrete Fourier transforms, the UCI can be dispersed to all frequency resources of the first time-frequency resources to obtain frequency diversity gain, and the requirement of the UCI on the transmission performance is met. However, when the UCI is transmitted by using the CP-OFDM waveform, the mapping position of the UCI on the first time-frequency resource is the position where the UCI is transmitted on the frequency domain. Therefore, when UCI is transmitted using a CP-OFDM waveform, frequency diversity gain cannot be acquired. Therefore, it is necessary to consider that the resources of multiple frequencies scattered in the first time-frequency resource are used as the second time-frequency resource, so that the terminal device can acquire better frequency diversity gain as much as possible regardless of whether the terminal device transmits UCI using the waveform of SC-FDMA or CP-OFDM.

In addition, for the uplink service, after the network device schedules the terminal device 1 to transmit data of a service (e.g., an eMBB service) with low requirements on reliability and delay, if the terminal device 2 needs to transmit data of a service (e.g., a URLLC service) with high requirements on reliability and delay, the network device may schedule the terminal device 2 to occupy a part of resources allocated to the terminal device 1 to transmit data. Because data of a service with higher requirements on reliability and time delay is usually a resource with a short time length but a wide frequency, it is necessary to consider that the second time-frequency resource occupies a shorter time length to minimize the influence on the UCI by avoiding or reducing the occupation of the time resource of the second time-frequency resource when other terminal devices send the emergency service on the first time-frequency resource.

In consideration of the above factors, the embodiment of the present application describes the second time-frequency resource, specifically:

A. in the frequency domain, the second time-frequency resource may include N blocks of resources in frequency. Wherein N is a positive integer greater than or equal to 1.

Since the frequency diversity gain can be only embodied when the frequency width is wide, in this embodiment, by dividing the second time-frequency resource into N blocks of resources that are dispersed to multiple frequency domain positions of the first time-frequency resource, the terminal device can directly use the N blocks of resources that are dispersed to multiple frequency domain positions of the first time-frequency resource to transmit UCI when the frequency width of the first time-frequency resource is wide, and thus, the frequency diversity gain of UCI can be obtained, and the transmission performance of UCI is improved. Therefore, the terminal equipment can obtain the frequency diversity gain no matter the terminal equipment adopts the waveform based on SC-FDMA or the waveform based on CP-OFDM to transmit the UCI, as long as the UCI is transmitted on the second time-frequency resource comprising N blocks of resources distributed to a plurality of frequency domain positions of the first time-frequency resource, and the transmission performance of the UCI is further improved.

The terminal device determines a value of N, and the frequency starting position of each resource may include the following three ways:

the first mode is as follows: the value of N is determined by the terminal device according to the frequency width of the first time-frequency resource, and an offset value of the frequency start position of each resource of the N blocks of resources on the frequency relative to the frequency start position of the first time-frequency resource is preset.

Specifically, the value of N and the frequency width of the first time-frequency resource satisfy a first mapping relationship (that is, the first mapping relationship may include a correspondence between the frequency width of the first time-frequency resource and the value of N), and an offset value of a frequency start position of each resource of the N resources on the frequency relative to the frequency start position of the first time-frequency resource is preset, and the terminal device may determine the value of N according to the first mapping relationship and the frequency width of the first time-frequency resource. Meanwhile, the terminal device may add an offset value of a frequency start position of each of the N preset resources on the frequency relative to a frequency start position of the first time-frequency resource to the frequency start position of the first time-frequency resource to obtain the frequency start position of each of the N resources on the frequency.

For example, the first mapping relationship may be as shown in the following table 2:

TABLE 2

The offset value of the frequency starting position of each resource of the N preset resources in frequency relative to the frequency starting position of the first time-frequency resource may be, for example, as shown in the following table 3, specifically:

TABLE 3

W may be a frequency width of the first time-frequency resource, and Δ W may be a preset threshold, where the preset threshold is smaller than W.

Fig. 3 is a schematic diagram of a second time-frequency resource provided in an embodiment of the present application. As shown in the figure3, taking the example that the frequency width of the first time-frequency resource is greater than the second frequency width and less than or equal to the third frequency width, after the terminal device determines the first time-frequency resource, the terminal device may determine that the value of N is 3 according to the frequency width of the first time-frequency resource and table 2. I.e. the second time-frequency resource comprises 3 blocks of resources in frequency. Then, the terminal device may determine, according to the value of N and table 3, that the 3 blocks of resources in frequency, where an offset value of the frequency starting position of the first block of resources relative to the frequency starting position of the first time-frequency resource is 0, and an offset value of the frequency starting position of the second block of resources relative to the frequency starting position of the first time-frequency resource is 0

The frequency start position of the third block resource is offset from the frequency start position of the first time-frequency resource by an amount W-aw.

In this way, the terminal device adds the offset value of the first block resource to the frequency starting position of the first time-frequency resource to obtain the frequency starting position of the first block resource, adds the offset value of the second block resource to the frequency starting position of the first time-frequency resource to obtain the frequency starting position of the second block resource, and adds the offset value of the third block resource to the frequency starting position of the first time-frequency resource to obtain the frequency starting position of the third block resource. In this example, the frequency start position of the first block resource is the frequency start position of the first time-frequency resource. The frequency starting position of the second block of resources is the frequency starting position and of the first time-frequency resource

And the frequency starting position of the third block resource is the value obtained by adding the frequency starting position of the first time frequency resource and W-delta W. In this example, the resources of the N blocks of the second time-frequency resource in frequency may be as shown in (C) of fig. 3.

Taking the example that the frequency width of the first time-frequency resource is less than or equal to the first frequency width, after the terminal device determines the first time-frequency resource, the terminal device may determine that the value of N is 1 according to the frequency width of the first time-frequency resource and table 2. I.e. the second time-frequency resource comprises 1 block of resources. Then, the terminal device may determine, according to the value of N and table 3, that the offset value of the frequency starting position of the 1 block of resources relative to the frequency starting position of the first time-frequency resource is 0. In this way, the terminal device adds the offset value of the block resource to the frequency starting position of the first time-frequency resource, and the frequency starting position of the first block resource can be obtained. In this example, the frequency start position of the first block resource is the frequency start position of the first time-frequency resource. In this example, the resources of the N blocks of the second time-frequency resource in frequency may be as shown in (a) of fig. 3.

The size of the first time-frequency resource and the frequency width of each of the N blocks of the second time-frequency resource in the frequency resource shown in fig. 3 are merely exemplary, and the manner in which the terminal device determines the size of the second time-frequency resource will be described later.

It should be emphasized that the above tables 2 and 3 are only examples, and the first mapping relationship according to the embodiment of the present application, and the offset value of the frequency starting position of each resource of the preset N resources in the frequency domain relative to the frequency starting position of the first time-frequency resource is not limited to the above tables 2 and 3. In addition, the first mapping relationship and the offset value of the frequency starting position of each resource of the preset N resources on the frequency relative to the frequency starting position of the first time-frequency resource may be preset in the terminal device, or may be sent to the terminal device by the network device through a higher layer signaling or a control signaling before the embodiment is implemented.

The second mode is as follows: the value of N and the offset value of the frequency start position of each resource in the N blocks of resources on the frequency relative to the frequency start position of the first time-frequency resource are determined according to the frequency width of the first time-frequency resource.

Specifically, the value of N and the frequency width of the first time-frequency resource satisfy a first mapping relationship (that is, the first mapping relationship may include a correspondence relationship between the frequency width of the first time-frequency resource and the value of N), the offset value of the frequency start position of each resource in the N resources on the frequency relative to the frequency start position of the first time-frequency resource, and the frequency width of the first time-frequency resource satisfy a second mapping relationship (that is, the second mapping relationship includes a correspondence relationship between the offset value of the frequency start position of each resource in the N resources on the frequency relative to the frequency start position of the first time-frequency resource and the frequency width of the first time-frequency resource), and the terminal device may determine the value of N and the correspondence relationship between the frequency start position of each resource in the N resources on the frequency relative to the frequency width of the first time-frequency resource according to the first mapping relationship, the second mapping relationship, and the frequency width of the first time-frequency resource Offset value of the starting position. Then, the terminal device may add an offset value of the frequency start position of each of the N blocks of resources on the frequency with respect to the frequency start position of the first time-frequency resource to obtain the frequency start position of each of the N blocks of resources on the frequency.

Then, in this implementation, the second mapping relationship may be as shown in the following table 4, for example:

TABLE 4

Taking the example that the frequency width of the first time-frequency resource is greater than the first frequency width and less than or equal to the second frequency width, after the terminal device determines the first time-frequency resource, the terminal device may determine that the value of N is 2 according to the frequency width of the first time-frequency resource and table 4. I.e. the second time-frequency resource comprises 2 blocks of resources in frequency. Meanwhile, the terminal device may determine, according to table 4, that, in the 2 blocks of resources on the frequency, an offset value of a frequency starting position of the first block of resources with respect to a frequency starting position of the first time-frequency resource is 0, and an offset value of a frequency starting position of the second block of resources with respect to a frequency starting position of the first time-frequency resource is W- Δ W.

In this way, the terminal device adds the offset value of the first block resource to the frequency starting position of the first time-frequency resource to obtain the frequency starting position of the first block resource, and adds the offset value of the second block resource to the frequency starting position of the first time-frequency resource to obtain the frequency starting position of the second block resource. In this example, the frequency start position of the first block resource is the frequency start position of the first time-frequency resource. The frequency starting position of the second block of resources is the value obtained by adding the frequency starting position of the first time-frequency resource and W- Δ W. Then in this example the resources in frequency for the N blocks of second time-frequency resources may be as shown in fig. 3 (b).

It should be emphasized that table 4 is only an example, and the first mapping relationship and the second mapping relationship according to the embodiment of the present application are not limited to table 4. In addition, the first mapping relationship and the offset value of the frequency starting position of each resource of the preset N resources on the frequency relative to the frequency starting position of the first time-frequency resource may be preset in the terminal device, or may be sent to the terminal device by the network device through a higher layer signaling or a control signaling before the embodiment is implemented.

As shown in table 4, the second mapping relationship may implicitly indicate a value of N, so that the terminal device may implicitly determine the value of N according to the second mapping relationship and the frequency width of the first time-frequency resource, which is not described herein again.

The third mode is as follows: the value of N and the frequency start position of each resource in the N resources on the frequency are determined according to the first information sent by the network device.

The network device may send, to the terminal device, first information indicating that the second time-frequency resource includes N blocks of resources on the frequency and a frequency start position of each of the N blocks of resources on the frequency after determining the second time-frequency resource, and the terminal device may further determine, according to the first information sent by the network device, a value of N of the N blocks of resources on the frequency of the second time-frequency resource and a frequency start position of each of the N blocks of resources on the frequency. In a specific implementation, the network device may carry the first information in a scheduling grant for scheduling the first time-frequency resource and send the first information to the terminal device, or the network device sends the first information to the terminal device through a high-level signaling.

Optionally, a corresponding relationship between the network device and the terminal device is preset between the network device and the terminal device, where the corresponding relationship is N values and a frequency start position of each resource in the N resources on the frequency. Wherein, different corresponding relations can correspond to an identifier (for example, an index number). In this way, the network device may indicate, to the terminal device, that the second time-frequency resource includes N blocks of resources on the frequency and a frequency start position of each of the N blocks of resources on the frequency by carrying the identifier in the first information. In this way, the signaling overhead when the network device sends the first information can be reduced.

It should be noted that the network device may also determine the value of N and the frequency start position of each resource by using the first manner and the second manner, which is not described herein again.

In addition, although the above embodiment only exemplifies three ways of determining the value of N and the frequency start position of each resource. However, it will be understood by those skilled in the art that the manner of determining the value of N provided in any of the above manners may be combined with the manner of determining the frequency starting position of each resource provided in other manners. Alternatively, the method for determining the frequency start position of each resource provided by any of the above methods may be combined with the method for determining the value of N provided by other methods. For example, the value of N may be determined according to the first manner, and the frequency start position of each block of resources may be determined according to the second manner, or the value of N may be determined according to the first manner, and the frequency start position of each block of resources may be determined according to the third manner, and so on, which will not be described again.

Optionally, the second time-frequency resource includes N blocks of resources on the frequency, where the N blocks of resources on the frequency are discontinuous resources, or J blocks of the N blocks of resources on the frequency are continuous, and the other N-J blocks are discontinuous. Wherein J is not more than N.

B. In the time domain, the time length of the second time frequency resource is a first length. The time length here refers to the number of symbols occupied by the time-frequency resource in the time domain.

The determining, by the terminal device, the time length of the second time-frequency resource may include the following two ways:

the first mode is as follows: the first length is determined by the terminal device according to the time length of the first time-frequency resource.

Specifically, the first length and the time length of the first time-frequency resource satisfy a third mapping relationship (that is, the third mapping relationship includes a corresponding relationship between the time length of the first time-frequency resource and the first length), and the terminal device may determine the first length according to the third mapping relationship and the time length of the first time-frequency resource.

For example, the third mapping relationship may be shown in table 5 below:

TABLE 5

Numbering	Time length of first time-frequency resource	First length
				1	1 time slot	7 symbols
2	2 time slots	1 time slot
			3	3 time slots	1.5 time slots

Wherein, the 1 slot may include 14 symbols.

Taking the time length of the first time-frequency resource as 2 time slots as an example, after the terminal device determines the first time-frequency resource, the terminal device may determine that the first length is 1 time slot according to the time length of the first time-frequency resource and table 5. That is, the time length of the second time-frequency resource is 1 time slot.

It should be emphasized that table 5 is merely an example, and the third mapping relation according to the embodiment of the present application is not limited to table 5. In addition, the third mapping relationship may be preset in the terminal device, or may be sent to the terminal device by the network device through a higher layer signaling or a control signaling before the embodiment is implemented.

Or, optionally, the first length and the time length of the third time frequency resource satisfy a fourth mapping relationship (that is, the fourth mapping relationship includes a corresponding relationship between the time length of the third time frequency resource and the first length), and the terminal device may determine the first length according to the fourth mapping relationship and the time length of the third time frequency resource. The third time-frequency resource refers to a resource used by the terminal device to transmit the first physical uplink control channel.

As described above, the terminal device may send UCI on the physical uplink control channel, but if the terminal device needs to send the physical uplink shared channel at the same time. On one hand, the capability of the terminal device may not support the simultaneous transmission of the physical uplink control channel and the physical uplink shared channel; on the other hand, Intermodulation Interference (IMD) between signals transmitted by the physical uplink control channel and the physical uplink shared channel also results in poor receiving performance of both channels. Therefore, the terminal device determines a part of resources in the time-frequency resources of the physical uplink shared channel to be used for sending the uplink control information. Considering the delay requirement of the uplink control information, the time length of the resource occupied by the physical uplink shared channel when being transmitted and the time length of the resource occupied by the physical uplink control channel when being transmitted satisfy the fourth mapping relation. So as to guarantee the time delay requirement of the uplink control information. In particular, the first market price length is equal to the time length of the third time-frequency resource.

The second mode is as follows: the first length is determined according to second information sent by the network equipment.

Specifically, after determining the second time-frequency resource, the network device may send, to the terminal device, second information indicating that the time length of the second time-frequency resource is the first length, and after receiving the second information sent by the network device, the terminal device may determine, according to the second information, that the time length of the second time-frequency resource is the first length. In a specific implementation, the network device may carry the second information in a scheduling grant for scheduling the first time-frequency resource and send the second information to the terminal device, or the network device sends the second information to the terminal device through a high-level signaling.

Optionally, a plurality of first time lengths are preset between the network device and the terminal device. Wherein each first time length corresponds to an identifier (e.g., an index number). In this way, the network device may indicate the time length of the second time-frequency resource to the terminal device as the first length by carrying the identifier in the second information. In this way, the signaling overhead when the network device sends the second information can be reduced.

The third mode is as follows: the first length is predetermined.

Specifically, the first length is a preset length, that is, the first length is a fixed value, and the terminal device may directly determine that the time length of the second time-frequency resource is the first length. The preset first length may be preset in the terminal device, or may be sent to the terminal device by the network device through a high-level signaling or a control signaling before the embodiment is implemented.

It should be noted that the network device may also determine the first length by using the first manner and the third manner, which is not described herein again.

C. In the time domain, the second time-frequency resource may include M blocks of resources in time. Wherein M is a positive integer greater than or equal to 1.

In a specific implementation, the time starting position of each of the M blocks of resources in time may be constrained according to the symbols mapped by the DMRS, so that the second time-frequency resource is a resource on a symbol close to the DMRS. Therefore, when the terminal device uses the second time-frequency resource to transmit the UCI, the demodulation performance of the UCI can be improved.

The determining, by the terminal device, a value of M, and a time starting point position of each resource in the M resources may include the following three ways:

the first mode is as follows: the value of M is determined according to the time length of the first time-frequency resource, and the offset value of the time starting position of each resource of the M blocks of resources in time relative to the time starting position of the first time-frequency resource is preset.

Specifically, the value of M and the time length of the first time-frequency resource satisfy a fourth mapping relationship (that is, the fourth mapping relationship may include a correspondence between the time length of the first time-frequency resource and the value of M), and an offset value of a time start position of each resource of the M blocks of resources in time with respect to the time start position of the first time-frequency resource is preset, and the terminal device may determine the value of M according to the fourth mapping relationship and the time length of the first time-frequency resource. Then, the terminal device may add an offset value of the time starting position of each of the M blocks of resources in time with respect to the time starting position of the first time-frequency resource to obtain the time starting position of each of the M blocks of resources in time.

For example, the fourth mapping relationship may be as shown in the following table 6:

TABLE 6

The offset value of the time starting position of each resource of the preset M blocks of resources in time relative to the time starting position of the first time frequency resource may be, for example, as shown in the following table 7, specifically:

TABLE 7

The T may be a time length of the first time-frequency resource, the Δ T may be a preset threshold, the preset threshold may be determined according to a symbol where the DMRS is located, and the X may be an offset value of a first symbol after the symbol where the DMRS is located with respect to a time start position of the first time-frequency resource.

Taking the example that the time length of the first time-frequency resource is greater than the first time threshold and is less than or equal to the second time threshold, after the terminal device determines the first time-frequency resource, the terminal device may determine that the value of M is 3 according to the time length of the first time-frequency resource and the table 6. I.e. the second time-frequency resource comprises 2 blocks of resources in time. Then, the terminal device may determine, according to the value of M and table 7, that the offset value of the time starting position of the 2 blocks in the time resources is X relative to the time starting position of the first time-frequency resource, and the offset value of the time starting position of the second block in the time resources is T- Δ T relative to the time starting position of the first time-frequency resource.

In this way, the terminal device adds the offset value of the first block resource of the 2 blocks of resources in time to the time starting position of the first time-frequency resource, so as to obtain the time starting position of the first block resource of the 2 blocks of resources in time, and adds the offset value of the second block resource of the 2 blocks of resources in time to the time starting position of the first time-frequency resource, so as to obtain the time starting position of the second block resource of the 2 blocks of resources in time. In this example, the time start position of the first block resource in the 2 blocks of resources in time is a value obtained by adding X to the time start position of the first time/frequency resource. The time starting position of the second block resource in the 2 blocks of resources in time is the value obtained by adding the time starting position of the first time-frequency resource and T-delta T.

It should be emphasized that the above tables 6 and 7 are only examples, and the fourth mapping relationship according to the embodiment of the present application, and the offset value of the time starting position of each resource of the preset M blocks of resources in time relative to the time starting position of the first time frequency resource are not limited to the above tables 6 and 7. In addition, the fourth mapping relationship and the offset value of the time starting position of each resource in the M preset blocks of resources in time relative to the time starting position of the first time-frequency resource may be preset in the terminal device, or may be sent to the terminal device by the network device through a high-layer signaling or a control signaling before the embodiment is implemented.

The second mode is as follows: the value of M and the offset value of the time start position of each resource in the M blocks of resources in time relative to the time start position of the first time-frequency resource are determined according to the time length of the first time-frequency resource.

Specifically, the value of M and the time length of the first time-frequency resource satisfy a fourth mapping relationship (that is, the fourth mapping relationship may include a correspondence between the time length of the first time-frequency resource and the value of M), the offset value of the time start position of each resource in the M blocks of resources in time with respect to the time start position of the first time-frequency resource, and the time length of the first time-frequency resource satisfy a fifth mapping relationship (that is, the fifth mapping relationship includes a correspondence between the offset value of the time start position of each resource in the M blocks of resources in time with respect to the time start position of the first time-frequency resource and the time length of the first time-frequency resource), and the terminal device may determine the value of M and the time start position of each resource in the M blocks of resources in time with respect to the time length of the first time-frequency resource according to the fourth mapping relationship, the fifth mapping relationship, and the time length of the first time-frequency resource, and determine the value of M and the time start position of each resource in the M blocks of resources in time with respect to the time length of the first time-frequency resource according to the fourth mapping relationship, the fifth mapping relationship and the time length of the first time-frequency resource Offset value of the start position. Then, the terminal device may add an offset value of the time starting position of each of the M blocks of resources in time with respect to the time starting position of the first time-frequency resource to obtain the time starting position of each of the M blocks of resources in time.

Then, in this implementation, the fifth mapping relationship may be as shown in the following table 8, for example:

TABLE 8

Taking the example that the time length of the first time-frequency resource is greater than the second time threshold and is less than or equal to the third time threshold, after the terminal device determines the first time-frequency resource, the terminal device may determine that the value of M is 3 according to the time length of the first time-frequency resource and the table 6. I.e. the second time-frequency resource comprises 3 blocks of resources in time. Meanwhile, the terminal device may determine, according to table 8, that, in the 3 blocks of resources in time, an offset value of a time starting position of the first block of resources with respect to a time starting position of the first time-frequency resource is X, and an offset value of a time starting position of the second block of resources with respect to a time starting position of the first time-frequency resource is X

The offset value of the time starting position of the third block resource relative to the time starting position of the first time frequency resource is T-delta T.

In this way, the terminal device adds the offset value of the first block resource in the 3 blocks of time resources to the time starting position of the first time-frequency resource to obtain the time starting position of the first block resource in the 3 blocks of time resources, and adds the offset value of the second block resource in the 3 blocks of time resources to the time starting position of the first time-frequency resourceAdding the time start positions to obtain the time start position of the second resource of the 3 resources, and adding the offset value of the third resource of the 3 resources to the time start position of the first time-frequency resource to obtain the time start position of the third resource of the 3 resources. In this example, the frequency start position of the first block resource of the 3 blocks of time resources is a value obtained by adding X to the time start position of the first time-frequency resource, and the frequency start position of the second block resource of the 3 blocks of time resources is a value obtained by adding X to the time start position of the first time-frequency resource

And the frequency starting position of the second block resource in the 3 blocks of resources on time is the value obtained by adding the time starting position of the first time-frequency resource and the T-delta T.

It should be emphasized that table 8 is merely an example, and the fifth mapping relationship according to the embodiment of the present application is not limited to table 8. In addition, the fifth mapping relationship may be preset in the terminal device, or may be sent to the terminal device by the network device through a higher layer signaling or a control signaling before the embodiment is implemented.

As shown in table 8, the fifth mapping relationship may implicitly indicate a value of M, so that the terminal device may implicitly determine the value of M according to the fifth mapping relationship and the time length of the first time-frequency resource, which is not described herein again.

The third mode is as follows: the value of M and the time start position of each resource in the M blocks of resources in time are determined according to the third information sent by the network device.

After determining the second time-frequency resource, the network device may send, to the terminal device, third information indicating that the second time-frequency resource includes M blocks of resources in time and a time start position of each of the M blocks of resources in time, and the terminal device may further determine, according to the third information sent by the network device, a value of M of the second time-frequency resource and a time start position of each of the M blocks of resources in time. In a specific implementation, the network device may carry the third information in a scheduling grant for scheduling the first time-frequency resource and send the third information to the terminal device, or the network device sends the first information to the terminal device through a high-level signaling.

Optionally, a value of M and a correspondence between a time start position of each resource of M blocks of resources in time are preset between the network device and the terminal device. Wherein, different corresponding relations can correspond to an identifier (for example, an index number). In this way, the network device may indicate, to the terminal device, that the second time-frequency resource includes M blocks of resources in time and a time start position of each block of resources in the M blocks of resources in time by carrying the identifier in the third information. In this way, the signaling overhead when the network device sends the third information can be reduced.

It should be noted that the network device may also determine the value of M and the time start position of each resource by using the first manner and the second manner, which is not described herein again.

In addition, although the above embodiment only exemplifies three ways of determining the value of M and the time start position of each resource block. However, it will be understood by those skilled in the art that the manner of determining the value of M provided in any of the above manners may be combined with the manner of determining the time starting position of each resource provided in other manners. Alternatively, the manner of determining the time starting position of each resource provided by any of the above manners may be combined with the manner of determining the value of M provided by other manners. For example, the value of M may be determined according to the first manner, and the time start position of each block of resources may be determined according to the second manner, or the value of M may be determined according to the first manner, and the time start position of each block of resources may be determined according to the third manner, and so on, which will not be described again.

Optionally, the second time-frequency resource includes M blocks of resources in time, where the M blocks of resources in time are discontinuous resources, or I blocks of the M blocks of resources in frequency are continuous, and other M-I blocks are discontinuous. Wherein I is not greater than M.

D. The second time frequency resource comprises L time frequency resource units. The time-frequency Resource unit may be, for example, a Resource Element (RE). One RE includes resources consisting of one Symbol in time and one subcarrier in frequency, and one RE may be used to transmit an uplink shared channel or one Coded Symbol (Coded Symbol) of uplink control information.

Specifically, the value of L can be determined according to a scale factor (β)_offset) And (4) determining. In particular, the terminal equipment can be implemented according to beta_offsetAnd the following formula (1), determining the number L of the time frequency resource units of the second time frequency resource. The above formula (1) can be represented as follows, for example:

wherein, O represents the number of UCI bits, G represents the number of resource elements included in the PUSCH, and T represents the number of bits included in the UL-SCH transmitted on the PUSCH.

By setting beta_offsetIn this way, the size of the time-frequency unit of the terminal device transmitting the UL-SCH in the PUSCH can be adjusted. The modulation coding modes corresponding to the transmission of the UL-SCH and the transmission of the UCI in the PUSCH are different, so that the requirements of different target receiving performances of the UL-SCH and the UCI are met.

Future 5G communication systems include a variety of services. Different services have different requirements on latency and/or reliability. Therefore, in this embodiment, the scaling factors for determining the number of resource units for transmitting UCI in PUSCH, which correspond to different services, are different, so as to meet different requirements of UCI of different services on delay requirements and/or reliability. For example: and when the UCI is the UCI corresponding to the first service, the scaling factor is a first value, and when the UCI is the UCI corresponding to the second service, the scaling factor is a second value. Wherein the delay requirements and/or reliability requirements of the first service and the second service are different.

When the first service is an eMBB service and the second service is a URLLC service, the requirements of the eMBB service on the transmission reliability and the time delay are lower than those of the URLLC service, so the requirements of the eMBB service and the URLLC service on the transmission performance of UCI corresponding thereto are also different. Therefore, the network device may indicate, to the terminal device, β corresponding to the eMBB service through the fourth information after determining the second time-frequency resource_offset(e.g., the first value) and beta corresponding to URLLC service_offset(e.g., a second value). Thus, when the terminal device determines that the currently transmitted UCI corresponds to the eMBB service, the terminal device may determine the number of time-frequency resource units of the second time-frequency resource that transmits the UCI by using the first value. When the terminal device determines that the currently transmitted UCI corresponds to the URLLC service, the terminal device may determine the number of time-frequency resource units of the second time-frequency resource that transmits the UCI by using the second value.

It should be noted that, the network device may also determine the value of L by using the scale factor in the above manner, which is not described again. However, it will be appreciated by those skilled in the art that the above equation (1) is only one way to determine the number L of time-frequency resource units of the second time-frequency resource according to the scale factor. The terminal device and the network device may also use other existing manners to determine the number L of the time-frequency resource units of the second time-frequency resource by using the scale factor, which is not described again.

Optionally, the correspondence between the value of the scaling factor and the service to which the UCI belongs may be preset on the terminal device. In some embodiments, the terminal device may further receive fourth information sent by the network device and used for indicating the correspondence, so that the terminal device may determine the value of L according to the fourth information and the service to which the UCI belongs. And the terminal equipment receives fourth information sent by the network equipment, wherein the fourth information is used for indicating a first value and a second value of the scale factor and a corresponding relation between the first value and the second value of the scale factor and a service to which the uplink control information belongs. That is, the terminal device determines whether the scaling factor to be used is the first value or the second value according to the fourth information and the service to which the UCI belongs, and then determines the value of L according to the value of the scaling factor. In a specific implementation, the network device may carry the fourth information in a scheduling grant for scheduling the first time-frequency resource and send the fourth information to the terminal device, or the network device sends the fourth information to the terminal device through a high-level signaling.

The terminal device may determine, by the means listed in the above a-D, that the second time-frequency resource includes N blocks of resources in frequency, and a starting position of the frequency of each of the N blocks of resources, that the second time-frequency resource includes M blocks of resources in time, and a starting position of the time of each of the M blocks of resources in time, and that the second time-frequency resource includes a total length (i.e., a first length) occupied by the M blocks of resources in time, and after the number of time-frequency resource units included in the second time-frequency resource, a specific position of the second time-frequency resource on the first time-frequency resource may be determined according to part or all of the information. I.e. the specific location of the L time-frequency resource elements on the first time-frequency resource.

For example, the terminal device determines, according to a first preset rule, positions of L time-frequency resource units included in the second time-frequency resource in the first time-frequency resource on the first time-frequency resource according to that the time length of the second time-frequency resource is the first length, the second time-frequency resource includes N blocks of resources in frequency, and the starting position of the frequency of each block of resources in the N blocks of resources. In the following figures, the first length is 3 symbols, N is 2, the starting positions of the N-2 resource blocks are F1 and F2, respectively, and L is 31. The first mapping rule is that the resources with the highest frequency in the 1 st resource in the N resources are mapped according to the time sequence.

Fig. 4 is a schematic diagram of another second time-frequency resource provided in the embodiment of the present application. As shown in fig. 4, when the first mapping rule shown in fig. 4 is adopted, the terminal device may first determine each time-frequency resource unit located on the highest frequency according to the time sequence on the highest frequency of the 1 st block of resources. Then, the terminal device determines each time-frequency resource unit located on the highest frequency according to the time sequence on the highest frequency of the 2 nd block of resources. Then, the terminal device determines each time-frequency resource unit located at the second highest frequency according to the time sequence on the second highest frequency of the 1 st resource. Then, the terminal device determines each time-frequency resource unit located at the second highest frequency according to the time sequence on the second highest frequency of the 2 nd resource. And so on until determining the position of the last time-frequency resource unit (i.e. number 31) of the 31 time-frequency resource units.

For another example, the terminal device determines, according to a first preset rule, positions of L time-frequency resource units included in the second time-frequency resource in the first time-frequency resource on the first time-frequency resource according to that the time length of the second time-frequency resource is the first length, the second time-frequency resource includes N blocks of resources in frequency, and the starting position of the frequency of each block of resources in the N blocks of resources. In the following figures, the first length is 3 symbols, N ═ 2, where the real positions of the N ═ 2 block resources are F1 and F2, respectively, and L ═ 31. The terminal device determines

Where P is the number of symbols included in the first length, and P is 3, then Q is 5.

The first preset rule may, for example, include that the L time-frequency resource units are sequentially mapped to the first time-frequency resource unit from high to low according to the frequency of the resource of the N blocks first, and then the M discontinuous time resources are mapped to the first time-frequency resource unit from early to late. According to the sequence, the corresponding positions of the L time frequency resource units are the positions of the second time frequency unit in the first time frequency unit.

Fig. 5 is a schematic diagram of another second time-frequency resource provided in the embodiment of the present application. As shown in fig. 5, when the first mapping rule shown in fig. 5 is adopted, the terminal device may first determine each time-frequency resource unit located on the first symbol according to the sequence from high to low in frequency on the first symbol of the 1 st block of resources. Then, the terminal device determines each time-frequency resource unit located on the first symbol according to the sequence of the frequency from high to low on the first symbol of the 2 nd block resource. Then, the terminal device determines each time-frequency resource unit located on the 2 nd symbol according to the sequence of the frequency from high to low on the first symbol of the 1 st block of resources. Then, the terminal device determines each time-frequency resource unit located on the 2 nd symbol according to the sequence of the frequency from high to low on the 2 nd symbol of the 2 nd block resource. And so on until determining the position of the last time-frequency resource unit (i.e. number 31) of the 31 time-frequency resource units.

As can be understood by those skilled in the art, the terminal device may determine the specific position of the second time-frequency resource on the first time-frequency resource according to at least two of the following information and a certain first preset rule:

the second time-frequency resource comprises N blocks of resources in frequency;

a starting position of a frequency of each of the N blocks of resources;

the second time-frequency resource comprises M blocks of resources in time;

a time starting point position of each of the M blocks of resources;

the second time-frequency resource comprises the total length occupied by the resource of the M blocks in time (namely, the first length);

the number of the time frequency resource units included in the second time frequency resource.

It should be noted that, the first preset rule includes, but is not limited to, the preset rules listed in this embodiment, and as long as a certain preset rule is adopted to determine the second time-frequency resource according to the information, the scope of the protection of the embodiment of the present application is included.

After determining the specific location of the second time-frequency resource from the first time-frequency resource, the terminal device may map the uplink control information to the second time-frequency resource according to a second preset rule. Optionally, the second preset rule may be a time-before-frequency mapping rule, or may be a frequency-before-time mapping rule.

It should be noted that, the steps of determining, by the terminal device, the position of the second time-frequency resource in the first time-frequency resource and mapping the uplink control information to the second time-frequency resource by the second preset rule may be performed sequentially and simultaneously.

It can be understood that, when the control information UCI includes a plurality of information, the method for determining the second time-frequency resource by the terminal device may be applied to a result obtained by sequentially concatenating the various information.

The UCI includes a first UCI (HARQ-ACK), a second UCI (ri), and a third UCI (CQI-PMI), and the terminal device may sequentially cascade the data sequence encoded by the first UCI, the data sequence encoded by the second UCI, and the data sequence encoded by the third UCI and then map the data sequence to the second time-frequency resource. That is, the encoded data sequences of a plurality of information are concatenated in sequence to form a total encoded data sequence. Then, the terminal device may map the total encoded data sequence to a second time-frequency resource, so as to send the UCI to the network device through the second time-frequency resource.

Assume that the first UCI encoded data sequence is:

the second UCI encoded data sequence is:

the third UCI encoded data sequence is:

the end device may concatenate the first UCI-encoded data sequence, the second UCI-encoded data sequence, and the third UCI-encoded data sequence in sequence to form a UCI-encoded data sequence:

is marked as

Fig. 7 is a schematic diagram of another second time-frequency resource provided in the embodiment of the present application. Each a in the UCI-encoded data sequence may be data that can be carried by one RB, or may also be data that can be carried by one RE, and may specifically be determined according to a mapping granularity. Then, the terminal device may adopt a time-first frequency-second mapping rule for the above-mentioned signals

The mapping, i.e. the manner shown in fig. 7, is not described again. Or, the terminal device may adopt a mapping rule of frequency first and time second to perform mapping on the second time-frequency resource

The mapping, i.e. the manner shown in fig. 6, is not described again.

In addition, in some embodiments, when the terminal performs mapping in a manner of time first and frequency second, the terminal may perform mapping in a manner of random mapping on the same frequency after time is mapped to full, and then perform mapping in a higher manner, and so on until mapping of all data is completed. Correspondingly, when the terminal performs mapping in a frequency-first and time-second manner, the terminal may map the frequency in the same time domain symbol in a random mapping manner, then map the frequency in the second time domain symbol in a random mapping manner, and so on until all data are mapped. Optionally, mapping may be performed on the second time-frequency resource completely in a random manner. The embodiment does not limit how to map UCI on the second time-frequency resource.

It can be understood that, when the terminal device determines the second time-frequency resources corresponding to the UCI for the multiple UCIs on the first time-frequency resources in the manner described above, the terminal device may further apply the method for determining the second time-frequency resources to each UCI.

Taking the example that the terminal device determines the second time-frequency resources for the first UCI (HARQ-ACK), the second UCI (ri), and the third UCI (CQI-PMI) on the first time-frequency resources, respectively, that is, on the first time-frequency resources, according to the method for determining the second time-frequency resources described in the above embodiment, the second time-frequency resources for transmitting the first UCI are determined for the first UCI, the second time-frequency resources for transmitting the second UCI are determined for the second UCI, and the second time-frequency resources for transmitting the third UCI are determined for the third UCI, respectively.

Then, the terminal device may adopt a time-frequency mapping rule to encode the data sequence of the first UCI on the second time-frequency resource corresponding to the first UCI

And (6) mapping. Or, the terminal device may adopt a mapping rule of frequency first and time second to encode the data sequence of the first UCI on the second time-frequency resource corresponding to the first UCI

And (6) mapping.

Correspondingly, the terminal device may adopt a time-frequency mapping rule to encode the second UCI on the second time-frequency resource corresponding to the second UCI

And (6) mapping. Or, the terminal device may adopt a mapping rule of frequency before time to encode the data sequence of the second UCI on the second time-frequency resource corresponding to the second UCI

And (6) mapping.

Correspondingly, the terminal device may adopt a time-frequency mapping rule to encode the data sequence of the third UCI on the second time-frequency resource corresponding to the third UCI

And (6) mapping. Or, the terminal device may adopt a mapping rule of frequency first and time second to encode a data sequence of a third UCI on a second time-frequency resource corresponding to the third UCI

And (6) mapping.

Starting from the second symbol, a first dotted line frame from top to bottom in terms of frequency is taken as a second time frequency resource of the first UCI, a second dotted line frame is taken as a second time frequency resource of the second UCI, a third dotted line frame is taken as a second time frequency resource of the third UCI, then the following resources which are the same as the first dotted line frame are the second time frequency resources of the first UCI, the resources which are the same as the second dotted line frame are the second time frequency resources of the second UCI, and the resources which are the same as the third dotted line frame are the second time frequency resources of the third UCI. It should be noted that fig. 8 is only an illustration, and the present embodiment does not limit the resource unit of each UCI finally mapped on the second time-frequency resource.

In the method for transmitting control information provided in the embodiment of the present application, after determining the first time-frequency resource used for transmitting the data shared channel, the terminal device may determine the second time-frequency resource used for transmitting the control information from the first time-frequency resource, so that the terminal device may transmit the control information by using a part of the time-frequency resources on the first time-frequency resource, thereby implementing transmission of the control information in the 5G communication system.

As in the foregoing embodiments, the terminal device according to the embodiments of the present application may be a wireless terminal such as a mobile phone and a tablet computer, and therefore, taking the terminal device as a mobile phone as an example: fig. 13 is a block diagram of a structure of a terminal device in the embodiment of the present application when the terminal device is a mobile phone. Referring to fig. 13, the handset may include: radio Frequency (RF) circuitry 1110, memory 1120, input unit 1130, display unit 1140, sensors 1150, audio circuitry 1160, wireless fidelity (WiFi) module 1170, processor 1180, and power supply 1190. Those skilled in the art will appreciate that the handset configuration shown in fig. 13 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

The following describes each component of the mobile phone in detail with reference to fig. 13:

RF circuit 1110 may be used for receiving and transmitting signals during a message transmission or call, for example, receiving downlink information from a base station and then processing the received downlink information to processor 1180; in addition, the uplink data is transmitted to the base station. Typically, the RF circuitry includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 1110 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE)), e-mail, Short Messaging Service (SMS), and the like.

The memory 1120 may be used to store software programs and modules, and the processor 1180 may execute various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 1120. The memory 1120 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 1120 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 1130 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 1130 may include a touch panel 1131 and other input devices 1132. Touch panel 1131, also referred to as a touch screen, can collect touch operations of a user on or near the touch panel 1131 (for example, operations of the user on or near touch panel 1131 by using any suitable object or accessory such as a finger or a stylus pen), and drive corresponding connection devices according to a preset program. Alternatively, the touch panel 1131 may include two parts, namely, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 1180, and can receive and execute commands sent by the processor 1180. In addition, the touch panel 1131 can be implemented by using various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 1130 may include other input devices 1132 in addition to the touch panel 1131. In particular, other input devices 1132 may include, but are not limited to, one or more of a physical keyboard, function keys (e.g., volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The display unit 1140 may be used to display information input by the user or information provided to the user and various menus of the cellular phone. The Display unit 1140 may include a Display panel 1141, and optionally, the Display panel 1141 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, touch panel 1131 can be overlaid on display panel 1141, and when touch operation is detected on or near touch panel 1131, the touch operation is transmitted to processor 1180 to determine the type of touch event, and then processor 1180 provides corresponding visual output on display panel 1141 according to the type of touch event. Although in fig. 10, the touch panel 1131 and the display panel 1141 are two independent components to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 1131 and the display panel 1141 may be integrated to implement the input and output functions of the mobile phone.

The handset may also include at least one sensor 1150, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 1141 according to the brightness of ambient light, and the light sensor may turn off the display panel 1141 and/or the backlight when the mobile phone moves to the ear. As one type of motion sensor, the acceleration sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.

Audio circuitry 1160, speaker 1161, and microphone 1162 may provide an audio interface between a user and a cell phone. The audio circuit 1160 may transmit the electrical signal converted from the received audio data to the speaker 1161, and convert the electrical signal into a sound signal for output by the speaker 1161; on the other hand, the microphone 1162 converts the collected sound signals into electrical signals, which are received by the audio circuit 1160 and converted into audio data, which are then processed by the audio data output processor 1180, and then transmitted to, for example, another cellular phone via the RF circuit 1110, or output to the memory 1120 for further processing.

WiFi belongs to short-distance wireless transmission technology, and the cell phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 1170, and provides wireless broadband internet access for the user. Although fig. 13 shows the WiFi module 1170, it is understood that it does not belong to the essential constitution of the handset, and may be omitted entirely as needed within the scope not changing the essence of the embodiment of the present application.

The processor 1180 is a control center of the mobile phone, and is connected to various parts of the whole mobile phone through various interfaces and lines, and executes various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 1120 and calling data stored in the memory 1120, thereby performing overall monitoring of the mobile phone. Optionally, processor 1180 may include one or more processing units; for example, the processor 1180 may integrate an application processor, which handles primarily the operating system, user interfaces, and applications, among others, and a modem processor, which handles primarily wireless communications. It will be appreciated that the modem processor described above may not be integrated within processor 1180.

The mobile phone further includes a power supply 1190 (e.g., a battery) for supplying power to each component, and optionally, the power supply may be logically connected to the processor 1180 through a power management system, so that functions of managing charging, discharging, power consumption management, and the like are implemented through the power management system.
