Description

Information transmission method, device, related equipment and storage medium

Technical Field

The present application relates to the field of wireless communications, and in particular, to an information transmission method, apparatus, related device, and storage medium.

Background

An automatic repeat request (ARQ, automatic Repeat reQuest) mechanism is one of the basic functions of the radio link control (RLC, radio Link Control) layer to support acknowledged mode (AM, acknowledged Mode) RLC, enabling retransmission of RLC protocol data units (PDU, protocol Data Unit). That is, the ARQ mechanism is a set of mechanisms capable of implementing data retransmission in the RLC layer, and when RLC PDU transmission fails, the RLC layer may construct a new MAC service data Unit (SDU, service Data Unit) according to an instruction of a lower layer (i.e., a medium access Control (MAC, media Access Control) layer) and send the new MAC service data Unit to the MAC layer to implement data retransmission.

The hybrid automatic repeat request (HARQ, hybrid Automatic Repeat reQuest) mechanism is one of the important and basic functions of the MAC layer, and is a mechanism implemented by combining forward error correction (FEC, forward Error Correction) technology and ARQ mechanism.

In the related art, the HARQ mechanism can be used as a unique anchor point for air interface data transmission, and efficient data retransmission can be realized by means of the advantage that the transmitting end device can first perceive the air interface data transmission result based on the HARQ mechanism.

However, the transmitting device may make an incorrect decision on whether the data needs retransmission based on the HARQ mechanism, so that the data retransmission cannot be accurately implemented.

Detailed Description

The present application will be described in further detail with reference to the accompanying drawings and examples.

In the HARQ mechanism of the related art, for each HARQ Process (english may be expressed as HARQ Process), the receiving device may feed back ACK/NACK of a Transport Block (TB) (i.e., a data packet) to the transmitting device to implement new transmission (i.e., transmission of a new TB) and retransmission (i.e., retransmission of a TB) of data; in other words, the transmitting end device may perceive the data transmission state by detecting ACK/NACK fed back by the receiving end device. However, the sending end device may have a false detection or missed detection (such as a case of false detection of NACK as ACK, etc.) on the detection of ACK/NACK, which may result in failure of data transmission. That is, the sending end device detects that the ACK/NACK fed back by the receiving end device has an error probability, so that the sending end device cannot accurately make a decision on whether the TB of each HARQ process needs to be retransmitted, and there may be a case that the TB is not successfully sent, but the sending end device does not retransmit the TB because the NACK is erroneously detected as ACK.

As can be seen from the above description, in the related art, the transmitting device may not accurately sense the data transmission state based on the HARQ mechanism, and thus may not accurately implement data retransmission.

In practical application, a TB whose retransmission is not completed based on the HARQ mechanism can be identified and the retransmission of the TB completed based on the data ordering and data retransmission of the ARQ mechanism. In other words, the problem that data retransmission cannot be accurately achieved in the HARQ scheme can be solved by the ARQ scheme. However, this approach requires coexistence of ARQ mechanisms and HARQ mechanisms, which may increase the complexity of the protocol stack functions.

Therefore, it is necessary to consider how to solve the problem that data retransmission cannot be accurately achieved in the HARQ scheme in the scenario where the ARQ scheme and the HARQ scheme do not coexist.

Based on this, in various embodiments of the present application, the receiving end device feeds back the data transmission state of at least one HARQ process to the transmitting end device through the MAC CE, that is, the transmitting end device needs to demodulate and decode the MAC CE, so that the accuracy of the transmitting end device in detecting the data transmission state of the HARQ process can be improved, and further the transmitting end device can accurately determine whether the data needs to be retransmitted according to the data transmission state of the HARQ process, so that no-error judgment transmission of air interface data is realized based on the HARQ mechanism, and the robustness of the air interface is improved.

In addition, in various embodiments of the present application, the problem that data retransmission cannot be accurately implemented in the HARQ mechanism can be solved without an ARQ mechanism, so that the ARQ function can be deleted from the protocol stack function according to the requirement, thereby reducing the complexity of the protocol stack function.

and sending the MAC CE to the sending end equipment, wherein the MAC CE contains first information, and the first information indicates the data transmission state of at least one HARQ process.

In practical application, the data transmission status of the HARQ process may be understood as whether the data packet transmitted by the HARQ process is correctly transmitted (i.e., successfully transmitted), or may be understood as a result of the data packet transmitted by the HARQ process. I.e. the data transmission status of the HARQ process may comprise at least an ACK or NACK corresponding to at least one data packet transmitted by the HARQ process. It can be understood that after the transmitting end device receives the MAC CE containing the first information and obtains the data transmission state of the HARQ process fed back by the receiving end device, whether the at least one data packet needs to be retransmitted or not may be determined according to ACK or NACK corresponding to the at least one data packet; in case the data transmission state of the HARQ process comprises a NACK, the data transmission state of the HARQ process may be used to request retransmission of the data packet from the sender device, in other words, the data transmission state of the HARQ process may trigger the sender device to retransmit the data packet.

In practice, the packet may also be referred to as a TB, and a packet may be understood as a MAC PDU. Since one MAC PDU usually carries a plurality of data packets of an upper layer protocol layer (i.e., a plurality of RLC PDUs, i.e., a plurality of MAC SDUs), if the receiving end device adopts an ARQ mechanism to feed back a data transmission state to the transmitting end device, one ACK/NACK needs to be fed back for each RLC PDU; the receiving end equipment feeds back the data transmission state of the HARQ process to the transmitting end equipment through the MAC CE, and only one ACK/NACK is fed back for one MAC PDU; therefore, compared with the ARQ mechanism, the receiving end equipment feeds back the data transmission state of the HARQ process to the transmitting end equipment through the MAC CE, so that the cost of ACK/NACK feedback can be saved, namely the resource consumption for feeding back the ACK/NACK can be reduced. For example, assuming that one MAC PDU contains 100 RLC PDUs, the receiving end device needs to feed back 100 ACK/NACK to the transmitting end device by adopting the ARQ mechanism, and the receiving end device feeds back the data transmission state of the HARQ process to the transmitting end device through the MAC CE, only one ACK/NACK needs to be fed back to the transmitting end device, so that the cost of ACK/NACK feedback can be saved.

In practical application, the HARQ process of the transmitting device may also be referred to as transmitting HARQ (english may be expressed as Tx HARQ); the HARQ process of the receiving device may also be referred to as receiving HARQ (english may be denoted as Rx HARQ).

In practical application, the transmitting end device may include a network device (specifically may include a base station), and the receiving end device may include a terminal; or the sender device may comprise a terminal and the receiver device may comprise a network device, accordingly. In addition, it can be appreciated that the MAC CE is used for interaction between the terminal and the base station, specifically a control signaling.

In practical applications, the terminal may also be referred to as a User Equipment (UE), and may also be referred to as a User.

In practical application, the data transmission state of the HARQ process may trigger the receiving device to send the MAC CE containing the first information to the transmitting device. In an exemplary case where the transmitting end device includes a network device and the receiving end device includes a terminal, when an HARQ process of the terminal receives new data sent by an HARQ process of the network device, that is, when the terminal receives a new data indication (NDI, new Data Indicator) in downlink control information (DCI, downlink Control Information) carried in a physical downlink control channel (PDCCH, physical Downlink Control CHannel), if the terminal determines that there is a packet that has not been successfully received, the terminal applies for a dynamic process Buffer (english may be expressed as Buffer), buffers the received new packet, and simultaneously sends a data retransmission request, that is, sends a MAC CE including first information to the network device, where the first information indicates a data transmission state of the HARQ process, and the data transmission state of the HARQ process includes at least NACK corresponding to the packet that has not been successfully received; after sending the MAC CE containing the first information to the network equipment, the terminal can wait for the network equipment to retransmit the corresponding data packet, if the retransmitted data packet is correctly received by the terminal, the terminal can send the MAC CE containing the first information to the network equipment again, wherein the first information indicates the data transmission state of the HARQ process, and the data transmission state of the HARQ process at least comprises the ACK corresponding to the retransmitted data packet; if the retransmitted data packet is not correctly received by the terminal, the terminal may also send the MAC CE containing the first information to the network device again, where the first information indicates a data transmission state of the HARQ process, and the data transmission state of the HARQ process at least includes a NACK corresponding to the retransmitted data packet.

In practical application, the receiving end device may also adopt a conventional HARQ mechanism to feed back the data transmission state to the transmitting end device while feeding back the data transmission state of at least one HARQ process to the transmitting end device through the MAC CE. In this case, the receiving end device may determine, according to its own perception (which may be understood as determination or judgment) of the data transmission status of the HARQ process, whether the decision of the transmitting end device on the data transmission status of the HARQ process by using the conventional HARQ mechanism is correct; in other words, the receiving end device may perceive whether the conventional HARQ mechanism is used for detecting ACK/NACK or not according to the data transmission state of the HARQ process, and may feed back the correct data transmission state of the HARQ process to the sending end device through the MAC CE, so as to improve data transmission efficiency. For example, for a data packet with transmission failure of one HARQ process, after the receiving end device feeds back NACK to the sending end device by using a conventional HARQ mechanism, it is found that the sending end device does not retransmit the data packet, but sends a new data packet, where the receiving end device may determine that the NACK corresponding to the data packet is missed by the sending end device, or may misdetect NACK corresponding to the data packet as ACK, that is, the receiving end device may determine that the data transmission state of the sending end device for the HARQ process is wrong, and may feed back the correct data transmission state of the HARQ process (that is, the NACK corresponding to the data packet) to the sending end device through MAC CE, so as to improve data transmission efficiency.

Based on this, in an embodiment, the at least one HARQ process may include at least one first HARQ process, where the first HARQ process includes a HARQ process where the receiving device determines that the transmitting device is wrong in deciding a data transmission state.

The fact that the sending end device decides the data transmission state in an error way refers to the fact that the sending end device adopts a traditional HARQ mechanism to detect the ACK/NACK in a false detection or missing detection mode.

In practical application, the receiving end device may also feed back the data transmission state of the HARQ process of the new data currently received (i.e. the HARQ process corresponding to the currently received data packet) to the transmitting end device through the MAC CE.

Based on this, in an embodiment, the at least one HARQ process may further include at least one second HARQ process, where the second HARQ process includes an HARQ process corresponding to a data packet currently received by the receiving device.

In practical application, the MAC CE may also be referred to as an HARQ feedback MAC CE (english may be expressed as an harq_feedback MAC CE), for example, in a case where the transmitting end device includes a network device and the receiving end device includes a terminal, the MAC CE may be referred to as an uplink HARQ feedback MAC CE, etc.; the name of the MAC CE is not limited in the embodiment of the application, and the function of the MAC CE is realized.

In an embodiment, the MAC CE may further include second information indicating that the type of the MAC CE is a MAC CE for HARQ feedback.

In actual use, the second information may contain a logical channel identification (LCID, logical Channel IDentification), which may characterize that the type of the MAC CE is a MAC CE for HARQ feedback. Here, the LCID may be implemented using a free value (english may be expressed as Reserved) among values of LCID defined in the related art, such as a free value between 35 and 44; in other words, the value range of the LCID may be 35-44, and the type of the corresponding MAC CE is a MAC CE for HARQ feedback (i.e., harq_feedback MAC CE). In practical applications, the second information may also include an extended LCID (eclcid), and eLCID may characterize that the type of the MAC CE is a MAC CE for HARQ feedback. Here, the eLCID may be implemented using 33 (eLCID field corresponding to two octets) or 34 (eLCID field corresponding to one octet) of values of LCID defined in the related art; in other words, the eLCID may have a value of 33 or 34, and the type of the MAC CE is a MAC CE for HARQ feedback (i.e., harq_feedback MAC CE).

In an embodiment, the first information may include at least one of:

An identification of the at least one HARQ process; i.e. the identity of the at least one first HARQ process, or the identity of the at least one first HARQ process and the at least one second HARQ process;

A data transmission state of the at least one HARQ process;

The Number of HARQ processes corresponding to the first information (english may be expressed as Process Number).

In actual application, the identification of the HARQ Process may include an ID (PID, process ID) of the HARQ Process.

Or the identification of the HARQ process may include information capable of indicating a PID,

For example, considering that the definition of a Slot (Slot) n in which a network device transmits downlink data in a physical downlink shared channel (PDSCH, physical Downlink SHARED CHANNEL) and a HARQ feedback Slot (Slot) n+k of ACK/NACK transmitted by a network device receiving terminal are given in the related art, where K may be understood as a time offset from downlink data to uplink feedback, and may be represented as dl-DataToUL-ACK, a value of dl-DataToUL-ACK may be 0 to 15, that is, k=0 to 15 slots, a value of slots may be determined based on different subcarrier intervals (SCS, sub-CARRIER SPACE), a number of slots included in one subframe (subFrame, typically 1 millisecond (ms)) corresponding to different SCS is different, if one Slot subFrame includes one Slot, a length of each Slot is 1ms, and if one Slot subFrame includes two slots, a length of each Slot is 0.5; and, considering that the network device and the terminal can both know the association relationship between K and PID in the process of data transmission, the identification of the HARQ process can be represented by K.

Based on this, in an embodiment, the identification of the HARQ process may be represented by a time offset K for the transmitting end device to transmit downlink data to the receiving end device and/or for uplink feedback.

Here, it may be understood that, in a case where the transmitting end device transmits downlink data, the receiving end device transmits uplink data, and/or performs uplink feedback, the transmitting end device may include a network device, and the receiving end device may include a terminal. For example, as shown in fig. 1, in a case where the transmitting end device includes a network device and the receiving end device includes a terminal, a MAC CE fed back by the terminal in the same slot may indicate data transmission states of at most 8 HARQ processes.

In an embodiment, the identification of the data transmission state may include one of:

Wherein, the first identifier and the second identifier can be understood as identifiers of data transmission states of the second HARQ process; the third and fourth identifications may be understood as identifications of data transmission states of the first HARQ process.

In practical application, in the case that the identifier of the data transmission state includes the third identifier or the fourth identifier, that is, in the case that the first information indicates the data transmission state of the at least one first HARQ process, or in the case that the receiving end device determines that the data transmission state of the transmitting end device for the HARQ process is wrong, after the transmitting end device receives the MAC CE including the first information, it may be checked whether the transmitting end device itself makes a wrong decision for the data transmission state of the HARQ process according to the first information.

Specifically, for each HARQ process indicated by the first information, if the identifier of the data transmission state of the HARQ process includes the third identifier or the fourth identifier, the sender device may determine whether the data packet currently transmitted by the HARQ process is the same as the data packet transmitted last, that is, determine whether the data packet currently transmitted by the HARQ process is a new data packet or a retransmitted data packet.

When the current data packet transmitted by the HARQ process is the same as the last data packet transmitted by the HARQ process, that is, when the current data packet transmitted by the HARQ process is a retransmitted data packet, the transmitting device may determine feedback corresponding to the last data packet transmitted by the HARQ process using the third identifier or the fourth identifier; if the identifier of the data transmission state includes the third identifier, the sending end device may determine that feedback corresponding to a data packet transmitted on the HARQ process is NACK, and determine that the data transmission state decision of the sending end device on the HARQ process is correct, where the data packet currently transmitted on the HARQ process is really a data packet that needs to be retransmitted; if the identifier of the data transmission state includes the fourth identifier, the sending end device may determine that the feedback corresponding to the data packet transmitted on the HARQ process is ACK, and determine that the data transmission state of the HARQ process is wrong, where the data packet currently transmitted by the HARQ process is actually a data packet that does not need to be retransmitted.

When the data packet currently transmitted by the HARQ process is different from the data packet currently transmitted by the previous HARQ process, that is, when the data packet currently transmitted by the HARQ process is a new data packet, the transmitting device may determine feedback corresponding to the data packet currently transmitted by the HARQ process by using the third identifier or the fourth identifier, that is, the transmitting device may determine that feedback corresponding to the data packet currently transmitted by the HARQ process is NACK; meanwhile, the transmitting terminal equipment can determine that the data transmission state decision of the HARQ process is correct.

Thus, as can be seen from the above description, the sending end device implements verification on whether to generate error judgment on the data transmission state of the HARQ process according to the first information, so that implementation of error judgment-free transmission of the air interface data based on the HARQ mechanism can be further ensured, and thus the robustness of the air interface is further improved.

In practical application, the specific implementation manners of the first identifier, the second identifier, the third identifier and the fourth identifier can be set according to requirements. For example, for the MCE CE shown in fig. 1, the MAC CE may indicate data transmission states of 8 HARQ processes, each K may occupy 2bits (bits) corresponding to the data transmission state, that is, the length of the identifier of each data transmission state may be 2bits, where the first identifier may be implemented by 00, the second identifier may be implemented by 01, the third identifier may be implemented by 10, and the fourth identifier may be implemented by 11.

In practical application, in order to reduce the overhead, the receiving end device may send the MAC CE containing the first information to the sending end device at a time defined by the related art and required to send data and/or send feedback to the sending end device.

Based on this, in an embodiment, the sending the MAC CE to the sender device may include:

Here, it may be understood that, in the case where the receiving end device transmits uplink data and/or performs uplink feedback, the transmitting end device may include a network device, and the receiving end device may include a terminal.

In practical application, the receiving end device sends uplink data and/or performs uplink feedback, which can be understood that the terminal needs to send uplink data and/or perform uplink feedback to the network device according to the time sequence relationship specified by the related technology, the dynamic indication of the network device, the own service requirement and other factors. In addition, the receiving end device performs uplink feedback, which can be understood that the terminal adopts a traditional HARQ mechanism to send ACK/NACK to the network device.

In practical application, in consideration of dynamic indication of network equipment, service requirements of the terminal and the like,

The receiving end device may not have a need for sending uplink data and/or performing uplink feedback at each time of sending uplink data and/or performing uplink 5 feedback specified in the related art, so that at least one HARQ process indicated by the first information may be understood as an effective HARQ process, that is, an HARQ process having a data transmission need; in other words, the K included in the MAC CE (such as the MAC CE shown in fig. 1) may be a valid K, and the valid K may be used for transmitting downlink data according to the network device and the terminal

And determining the dynamic indication, the service requirement of the terminal and other factors. For example, for MCE0CE shown in fig. 1, only k#0 may be valid, i.e., the HARQ process corresponding to k#0 is valid, or it may be understood that there is data transmitted by the HARQ process corresponding to k#0, or it may be understood that there is a need for feeding back the data transmission status by the HARQ process corresponding to k#0; or k#0, k#1, k#2, and k#3 may be valid, that is, HARQ processes corresponding to k#0, k#1, k#2, and k#3 are valid, or it may be understood that there is data transmitted by HARQ processes corresponding to k#0, k#1, k#2, and k#3, or it may be understood that there is a need to feed back a data transmission state by HARQ processes corresponding to k#0, k#1, 5k#2, and k#3.

Based on this, in an embodiment, the at least one HARQ process is an HARQ process in which downlink data is present in a first time range, the first time range being a time between a time at which uplink data is transmitted and/or uplink feedback is performed last to a time at which uplink data is currently transmitted and/or uplink feedback is performed

And the first time range is associated with time offset K for transmitting downlink data to the receiving end equipment 0 and transmitting uplink data and/or performing uplink feedback by the transmitting end equipment.

Wherein the at least one HARQ process is a HARQ process in which downlink data exists in the first time range, which may be understood as the at least one HARQ process is a valid HARQ process, or may be understood as the at least one HARQ process is a HARQ process in which there is a need to feed back a data transmission state.

5 In practical application, the first time range may be implemented by a slot (slot), and the association between the first time range and K may be determined based on a timing relationship specified by the related art. For example, for the MCE CE shown in fig. 1, in the case of uplink slot=2, according to the corresponding timing relationships between downlink and uplink specified in the related art, when slot=2, K that needs to be fed back is 2, 3, and 5, and at most, the timing n calculated by k#2, k#3, and k#5 in the MAC CE transmitted at this time is valid, that is, only the HARQ processes corresponding to k#2, k#3, and k#5 are valid; meanwhile, if the system only transmits downlink data in k#3 and k#5, K valid at this time is only k#3 and k#5. In addition, it can be understood that the transmitting device and the receiving device can identify whether K in the MCE CE is valid according to the specification of the related art, that is, identify whether the HARQ process indicated by the first information is valid.

In an embodiment, the sending the MAC CE to the sender device may include:

On uplink wireless resources, the MAC CE is sent to the sending end equipment; that is, at the time of transmitting uplink data and/or performing uplink feedback, the MAC CE is transmitted to the transmitting device on an uplink radio resource.

The uplink radio resources may include uplink radio resources pre-allocated by the network side, and in this case, the network device (the transmitting end device) may synchronously complete allocation of the scheduling resources when the downlink scheduling data is sent, that is, allocate the uplink radio resources for the MAC CE.

In practical application, the uplink radio resource may also include PUSCH for transmitting uplink data and/or performing uplink feedback.

Based on this, in an embodiment, the sending, on the uplink radio resource, the MAC CE to the sending end device may include:

transmitting corresponding uplink data and/or feedback data and the MAC CE to the transmitting end equipment through a PUSCH for transmitting the uplink data and/or carrying out uplink feedback; in other words, the corresponding uplink data and the feedback data are simultaneously transmitted to the transmitting end device and the MAC CE, or the corresponding uplink data and the MAC CE are simultaneously transmitted to the transmitting end device, or the corresponding feedback data and the MAC CE are simultaneously transmitted to the transmitting end device.

Specifically, in actual application, for a MAC CE that needs to be sent to the sending end device and includes first information, the receiving end device may determine whether the PUSCH exists in the corresponding uplink time (such as the corresponding slot), and if so, may send the MAC CE on the PUSCH; in other words, the MAC CE may be carried by the PUSCH. In addition, when the MAC CE and other data (uplink data and/or data for uplink feedback) carried on the PUSCH are simultaneously transmitted, the MAC CE may be included in a MAC PDU (i.e., TB carried on PUSCH); or the MAC CE and other data carried on the PUSCH may be separately transmitted in the same PUSCH resource block by using different coding and/or modulation modes.

Correspondingly, the embodiment of the application also provides an information transmission method which is applied to the transmitting terminal equipment and comprises the following steps:

Wherein in an embodiment, in case the identifier of the data transmission state includes the third identifier or the fourth identifier, the method may further include:

In an embodiment, the receiving the MAC CE sent by the receiving end device may include:

In an embodiment, the receiving the MAC CE sent by the receiving end device at the time of sending uplink data and/or performing uplink feedback may include:

In an embodiment, the receiving the MAC CE sent on the uplink radio resource at the time when the receiving end device sends uplink data and/or performs uplink feedback includes:

Correspondingly, the embodiment of the application also provides an information transmission method, as shown in fig. 2, which comprises the following steps:

step 201: the method comprises the steps that a receiving end device sends a MAC CE to a sending end device, wherein the MAC CE contains first information which indicates the data transmission state of at least one HARQ process;

Step 202: the transmitting end equipment receives the MAC CE transmitted by the receiving end equipment.

According to the information transmission method provided by the embodiment of the application, the receiving end equipment sends the MAC CE to the sending end equipment, the sending end equipment receives the MAC CE sent by the receiving end equipment, the MAC CE contains first information, and the first information indicates the data transmission state of at least one HARQ process. According to the scheme provided by the embodiment of the application, the receiving end equipment feeds back the data transmission state of at least one HARQ process to the sending end equipment through the MAC CE, namely the sending end equipment can acquire the data transmission state of at least one HARQ process after demodulating and decoding the MAC CE, so that the accuracy of the sending end equipment for detecting the data transmission state of the HARQ process can be improved, the sending end equipment can accurately judge whether the data need to be retransmitted or not according to the data transmission state of the HARQ process, the error-free judgment transmission of air interface data is realized based on an HARQ mechanism, and the robustness of an air interface is improved.

In addition, in various embodiments of the present application, by providing an explicit indication (i.e., the first information) for retransmission of a data packet in a new MAC CE format (such as the MAC CE shown in fig. 1), it is possible to implement data transmission without erroneous judgment, in other words, it is possible to enable HARQ processes of a receiving end device and a transmitting end device to obtain a data transmission state without erroneous judgment.

Third, in various embodiments of the present application, the transmitting end device may implement, according to the first information, checking whether to generate an error decision on the data transmission state of the HARQ process, so as to further ensure implementation of error-free transmission of the air interface data based on the HARQ mechanism, thereby further improving robustness of the air interface.

Fourth, in various embodiments of the present application, the problem that data retransmission cannot be accurately implemented in the HARQ mechanism can be solved without an ARQ mechanism, so that the ARQ function can be deleted from the protocol stack function according to the requirements, thereby reducing the complexity of the protocol stack function. Meanwhile, since one MAC PDU usually carries multiple RLC PDUs (i.e., MAC SDUs), if the receiving end device adopts an ARQ mechanism to feed back a data transmission state to the transmitting end device, one ACK/NACK needs to be fed back for each RLC PDU; the receiving end equipment feeds back the data transmission state of the HARQ process to the transmitting end equipment through the MAC CE, and only one ACK/NACK is fed back for one MAC PDU; therefore, compared with an ARQ mechanism, the scheme provided by the embodiment of the application can save the expense of ACK/NACK feedback, namely, can reduce the resource consumption of feedback ACK/NACK.

Fifth, in various embodiments of the present application, since the MAC CE including the first information is transmitted at the time of transmitting the uplink data and/or performing the uplink feedback, it is possible to save resources without increasing overhead.
