Technical Field

The present invention relates to communication technologies, and in particular, to a feedback information transmission method, a user equipment, and a network device.

Background

With the rapid development of wireless communication technology, networks require higher data transmission rates. In order to increase the data transmission rate, a Carrier Aggregation (CA) may be introduced into the network system to aggregate multiple carriers to provide a larger transmission bandwidth for data transmission. Since the maximum number of aggregation carriers that can be supported by the current ue is 5, and the maximum number of bits of feedback information for 5 carriers that can be supported by the ue on a Physical Uplink Control Channel (PUCCH) is limited. With the further opening of the white space spectrum or the fractional spectrum, in order to increase the peak transmission rate of the terminal, the user equipment needs to support a greater number of carrier aggregation, and thus the PUCCH needs to support feedback information with a greater number of bits.

In release 8 (Re-8 for short) technology of Long Term Evolution (Long Term Evolution, LTE for short), feedback information of a single codeword of all downlink subframes of each carrier in a Subframe Window (SW for short) is logically and bound, the bound feedback information of each carrier is sent to a network device on an uplink Subframe corresponding to the Subframe Window, and the bit number of the bound feedback information of each carrier is 1, so that the bit number of the feedback information sent to the network device is reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The scheme of each embodiment of the invention can be suitable for enhancing the scene of HARQ feedback information transmission between the user equipment and the network equipment in a Long term evolution (LTE-A) system or a later more advanced mobile communication system.

The embodiment of the invention provides a feedback information transmission method. The method may be performed by a user equipment. Fig. 1 is a flowchart of a feedback information transmission method according to an embodiment of the present invention. As shown in fig. 1, the method may include the following:

s101, if the total bit number of the feedback information of at least one carrier is greater than a preset bit number, dividing a subframe window corresponding to each carrier in the at least one carrier into at least one time domain window according to a preset time domain window subframe number, wherein the preset time domain window subframe number is greater than or equal to 2.

Specifically, the total number of bits of the feedback information may be a sum of the number of bits of the feedback information in a subframe window corresponding to each carrier of the at least one carrier. The total bit number of the feedback information may be obtained by adding the feedback information of the at least one carrier, where the feedback information of each carrier refers to the feedback information in the subframe window corresponding to each carrier. The preset number of bits may be a maximum number of bits for the ue to send feedback information to the network device. The preset number of bits may be determined, for example, according to the maximum number of downlink carriers of the ue, the maximum number of downlink subframes of a subframe window corresponding to each carrier, and a transmission mode of the ue. It should be noted that the ue may be in a CA scenario or in a non-CA scenario. The at least one carrier may include at least two carriers if the ue is in a CA scenario, and the number of carriers of the at least one carrier may include one carrier if the ue is in a non-CA scenario.

The number of subframes included in the subframe window corresponding to each carrier may be the number of downlink subframes corresponding to each carrier, which is determined by the ue according to the timeslot proportion corresponding to each carrier. The subframe window corresponding to each carrier may be a downlink subframe window formed by all downlink subframes corresponding to each carrier. The subframe ratios corresponding to different carriers in the at least one carrier may be the same or different, and then the number of subframes in the subframe window corresponding to different carriers in the at least one carrier may be the same or different. And dividing the sub-frame windows corresponding to different carriers according to the preset time domain window sub-frame number, wherein the obtained time domain windows corresponding to different carriers can be the same or different. Therefore, the sub-frame window corresponding to each carrier is divided into at least one time domain window according to the preset time domain window sub-frame number, which can be the time domain window corresponding to each carrier.

In order to ensure the capacity of the network when the ue performs data transmission through carrier aggregation of the at least one carrier, the time domain window may be divided only when the total bit number of the feedback information is greater than the preset bit number, that is, the step of dividing the subframe window corresponding to each carrier in the at least one carrier into at least one time domain window in S101 is performed. Correspondingly, if the total bit number of the feedback information is less than or equal to the preset bit number, the solutions of the embodiments of the present invention may not be executed, so as to directly send the feedback information of the at least one carrier in the subframe window corresponding to each carrier to the network device, and thus, there is no problem of capacity loss caused by an error in binding the feedback information.

That is to say, in S101 according to the first embodiment of the present invention, the sub-frame window corresponding to each carrier in at least one carrier is divided into at least one time domain window according to the preset time domain window sub-frame number, which may be executed under a preset trigger condition, where the trigger condition may be that the total bit number of the feedback information is greater than the preset bit number.

For example, if the number of aggregated carriers of the ue is K, that is, the number of carriers of the at least one carrier is K, where the number of bits of the codeword feedback information in the subframe window corresponding to the kth carrier may be the total number of bits of the feedback information of the at least one carrier in the subframe window corresponding to each carrier, which may be determined by the following formula (1).

In the formula (1), O_SBK is the number of carriers of the at least one carrier for the total number of bits of the feedback information, and thus K is greater than or equal to 1.

If the maximum bit number of the feedback information sent by the ue to the network device is 20, that is, the preset bit number is 20, the triggering condition for executing the feedback information transmission method in the embodiment of the present invention may be O_SB>20, if the total bit number O of the feedback information can be obtained according to the formula (1)_SBSatisfies the trigger condition, i.e. O_SBIf the number of the sub-frame windows is more than 20, dividing the sub-frame window corresponding to each carrier into at least one time domain window; if the total bit number O of the feedback information_SBNot fulfilling the trigger condition, i.e. O_SBIf the number of the carriers is less than or equal to 20, the feedback information of the at least one carrier in the subframe window corresponding to each carrier may be directly sent to the network device without performing the scheme of the embodiment of the present invention.

Wherein, the preset time domain window subframe number is the maximum subframe number included in the unit time domain window. The sub-frame window corresponding to each carrier is divided according to the preset time domain window sub-frame number, and the sub-frame included in the sub-frame window corresponding to each carrier may be divided by using the preset time domain window sub-frame number as a unit time domain window to obtain at least one time domain window. The number of subframes of each time domain window in the at least one time domain window is less than or equal to the preset number of subframes of the time domain window. For example, if the subframe number of the subframe window corresponding to each carrier is an integer multiple of the preset time domain window subframe number, the subframe number of each time domain window is equal to the preset time domain window subframe number. If the number of the sub-frames of the sub-frame window corresponding to each carrier is not an integral multiple of the number of the preset time domain window sub-frames, the number of the sub-frames of one time domain window in the at least one time domain window is smaller than the number of the preset time domain window sub-frames, and the number of the sub-frames of the other time domain windows is equal to the number of the preset time domain window sub-frames.

Because the preset time domain window subframe number is greater than or equal to 2, the number of the time domain windows after dividing the subframe window corresponding to each carrier according to the preset time domain window subframe number can be less than the subframe number in the subframe window corresponding to each carrier.

And S102, acquiring first binding feedback information of each carrier in the at least one carrier in each time domain window, wherein the first binding feedback information is obtained by performing logic AND on the codeword feedback information of all subframes in each time domain window.

It should be noted that, before acquiring the first bundling feedback information of each carrier in each time domain window in S102, the method may further include:

and obtaining the code word feedback information in all the subframes in each time domain window.

Optionally, the codeword feedback information in all subframes of each time domain window is obtained, for example, the codeword feedback information of all subframes in each time domain window is determined according to the feedback information of each codeword determined by the result of decoding and error correcting performed on each codeword received by each carrier on each downlink subframe and sent by the network device.

The first binding feedback information is obtained by logically and-binding the codeword feedback information in all subframes in each Time domain window, or may be obtained by Time domain binding (TB for short) the codeword feedback information in each Time domain window.

The bit number of the codeword feedback information of all subframes in the subframe window corresponding to each carrier may be the number of subframes in the subframe window corresponding to each carrier. The bit number of the first binding feedback information of each carrier in each time domain window, which is obtained by logically and-binding the codeword feedback information of all subframes of each carrier in each time domain window, may be 1, and then the bit number of the feedback information of each carrier in the at least one time domain window may be the number of the time domain windows corresponding to each carrier, that is, the number of the time domain windows of the at least one time domain window. Because the preset time domain window subframe number is greater than or equal to 2, the number of the time domain windows after dividing the subframe window corresponding to each carrier according to the preset time domain window subframe number can be less than the subframe number of the subframe window corresponding to each carrier. The first binding feedback information is obtained by logically and-binding the codeword feedback information of all subframes in each time domain window, and the bit number of the first binding feedback information can be smaller than the bit number of the codeword feedback information of all subframes in each time domain window. Therefore, the embodiment of the invention can reduce the bit number of the feedback information sent by the user equipment to the network equipment on the at least one carrier.

Meanwhile, the sub-frame window corresponding to each carrier is divided into at least one time domain window, so that the number of sub-frames in one time domain window corresponding to at least one carrier in the at least one carrier is smaller than the number of sub-frames in the sub-frame window corresponding to the carrier. Since the first binding feedback information is obtained by logically and-ing the codeword feedback information of all subframes in each time domain window, the first binding feedback information of each carrier in each time domain window is obtained, and the binding granularity of the binding feedback information sent to the network device on the at least one carrier can be reduced. If the binding feedback information has errors, only the code words of each subframe in the time domain window where the binding feedback information is located need to be retransmitted, and the code words of all subframes do not need to be retransmitted, so that the capacity loss caused by the binding feedback information is reduced.

The codeword feedback information of each subframe in each time domain window may be Hybrid Automatic Repeat reQuest (HARQ) feedback information, such as Acknowledgement (ACK) information or Negative Acknowledgement (NACK) information. The ACK information and the NACK information may be represented by 1 and 0, respectively. And, the information obtained after logically and-binding the codeword feedback information of all subframes in each time domain window, that is, the first binding feedback information can be used to represent the codeword receiving condition of each carrier in each time domain window while reducing the bit number of the feedback information.

For example, if the ACK information is represented by binary 1, the NACK information is represented by binary 0. Then, the information obtained by logically and-binding the codeword feedback information of all subframes of the first carrier in the first time domain window, that is, the first binding feedback information, may indicate, through binary 0, that the codeword feedback information of at least one subframe of the first carrier in the first time domain window is NACK information, and indicate, through binary 1, that the codeword feedback information of each subframe of the first carrier in the time domain window is ACK information.

S103, sending the first binding feedback information to the network equipment.

Specifically, the sending of the first bundled feedback information to the network device may be sending the first bundled feedback information to the network device through a PUCCH. Specifically, the first bundling feedback information is sent to the network device, and actually, the first bundling feedback information may be sent to the network device through the PUCCH on the uplink subframe corresponding to each time domain window.

It should be noted that, before sending the first binding feedback information to the network device in S103, the uplink subframe corresponding to each time domain window may also be determined according to the downlink subframe and the subframe ratio of each time domain window.

In the feedback information transmission method provided in the first embodiment of the present invention, if the total bit number of the feedback information of at least one carrier is greater than the preset bit number, the subframe window corresponding to each carrier in the at least one carrier may be divided into at least one time domain window according to the preset time domain window subframe number, where the preset time domain window subframe number is greater than or equal to 2; acquiring first binding feedback information of each carrier in each time domain window, wherein the first binding feedback information is obtained by performing logical AND on the codeword feedback information of all subframes in each time domain window, and sending the first binding feedback information to network equipment. The binding feedback information of each carrier, that is, the first binding feedback information, is bound in each time domain window, and the number of subframes of the time domain window corresponding to at least one carrier in the at least one carrier is less than the number of subframes of the subframe window corresponding to the one carrier.

Meanwhile, in the feedback information transmission method according to the first embodiment of the present invention, the first binding feedback information is obtained by logically and-ing the codeword feedback information of all subframes in each time domain window, and the first binding feedback information can also reduce the bit number of the feedback information sent to the network device on the at least one carrier, and transmit the feedback information of more carriers under the condition that the bit number fed back by the user device is limited, so that the number of aggregation carriers that can be actually supported by the user device can be increased, and the data transmission rate can be increased.

The embodiment of the invention also provides a feedback information transmission method. Fig. 2 is a flowchart of another feedback information transmission method according to an embodiment of the present invention. As shown in fig. 2, before dividing a subframe window corresponding to each carrier in at least one carrier into at least one time domain window according to a preset time domain window subframe number in S101 in the scheme of the embodiment, the method may further include:

s201, rounding up the ratio of the total bit number of the feedback information to the preset bit number, and determining the number of the preset time domain window subframes.

Specifically, if the maximum bit number of the feedback information sent by the ue to the network device is 20, that is, the preset bit number is 20, and the total bit number of the feedback information is O_SBThen it can be the total bit number O according to the feedback information_SBAnd the preset number of bits 20, which is determined by the following formula (2).

In the formula (2), W_TGThe preset time domain window subframe number. Since the size of the time domain window can be represented by the number of subframes of the time domain window, W_TGAlso for the predetermined time domain window size. Then S101 may be based on the preset time domain window subframe number W_TGAnd dividing a subframe window corresponding to each carrier in the at least one carrier into at least one time domain window. It should be noted that the ue may also determine the preset time domain window subframe number by using other manners according to the total bit number of the feedback information and the preset bit number, as long as it is ensured that the preset time domain window subframe number is greater than or equal to 2.

Assuming the total number of bits O of the feedback information_SBIs 40, then the preset time domain window subframe number W can be known from the formula (2)_TGCan be 2; if the total bit number O of the feedback information_SBIs 30, then the predetermined time domain window subframe number W is obtained by rounding up according to the formula (2)_TGMay be 2.

If the sub-frame number of the sub-frame window corresponding to each carrier is N, according to the preset time domain window sub-frame number W_TGAnd the number of at least one time domain window obtained after dividing the subframe window corresponding to each carrier is M. Then the preset time domain window subframe number W_TGThe subframe number N of the subframe window and the time domain window number M can satisfy the following formula (3).

If the number N of the sub-frames of the sub-frame window is an integral multiple of the number of the preset time domain window sub-frames, the number of the sub-frames of all the time domain windows in the M time domain windows corresponding to each divided carrier is equal to the number of the preset time domain window sub-frames. If the number of subframes N of the subframe number is not an integer multiple of the preset time domain window subframe number, the number of subframes of each time domain window corresponding to each divided carrier can be less than or equal to the preset time domain window subframe number, the number of subframes of the last time domain window in the M time domain windows corresponding to each carrier in the time domain from small to large can be less than the preset time domain window subframe number, and the number of subframes of the rest time domain windows is equal to the preset time domain window subframe number.

For example, if the number N of the sub-frames of the sub-frame window is an integer multiple of the number of the sub-frames of the predetermined time domain window, the number of the sub-frames of all the time domain windows in the M time domain windows corresponding to each carrier is equal to the number W of the sub-frames of the predetermined time domain window_TG. ThatThe obtained first bundling feedback information of each carrier in each time domain window may be determined according to the following formula (4), for example, how to logically and bundle the codeword feedback information of each carrier in each time domain window.

Wherein, for the binding feedback information of the kth carrier in the mth time domain window, f { } is a logical and binding function, and sequentially for the codeword feedback information of each subframe of the kth carrier in the mth time domain window. W_TGmW for the number of subframes per time domain window_TG，mW_TG+1，……(m+1)W_TG-1 is the subframe W of the m time domain window in turn_TG. If the number of bits of the codeword feedback information of the kth carrier in each subframe of the mth time domain window is 1, after performing logical and binding according to formula (4), the number of bits of the binding feedback information of the kth carrier in the mth time domain window obtained may also be 1.

The number of bits of the feedback information of the kth carrier in the mth time domain window is the number of bits, and then the number of bits of the feedback information of the kth carrier in the M time domain windows may be that the number of bits of the feedback information of the kth carrier in the M time domain windows may be 1, and then the number of bits of the feedback information of the kth carrier in the M time domain windows may be K × M. However, the bit number of the codeword feedback information of the kth carrier in each of the N subframes is 1, the bit number of the feedback information of the kth carrier in the N subframes may be N, and the total bit number of the feedback information of the K carriers in the N subframes may be K × N. Therefore, the feedback information transmission method can reduce the bit number of the feedback information sent by the user equipment to the network equipment.

It should be noted that, if the number N of subframes of the subframe number is not an integer multiple of the preset time domain window subframe number, the number of subframes of each time domain window corresponding to each carrier is less than or equal to the preset time domain window subframe number. For the time domain window with the subframe number equal to the preset time domain window subframe number, performing logic and binding on the code word feedback information of each carrier in each time domain window, and obtaining the first binding feedback information of each carrier in each time domain windowDetermined in a similar process as described in equation (4) above. For the time domain window with the number of subframes less than the preset time domain window subframe number, performing logic and binding on the codeword feedback information of each carrier in each time domain window, and determining the obtained first binding feedback information of each carrier in each time domain window by a similar process as described in the above formula (4), with the difference that the subframe number of the bound time domain window and the W described above are the same_TGIn contrast, the specific binding process is similar to the above process of this embodiment, and is not described herein again.

In addition, in the embodiment of the present invention, the codeword feedback information of all subframes of each carrier in each time domain window is bound according to the size of each time domain window, so that the binding granularity of the binding feedback information of each carrier in each time domain window in the embodiment may be the size of each divided time domain window, that is, the number of subframes of each time domain window. And each time domain window subframe number after division is determined by performing time domain window division on the subframe window corresponding to each carrier according to the preset time domain window subframe number, so that the subframe number of each time domain window is inevitably smaller than the subframe number of the subframe window corresponding to each carrier, namely, the feedback information transmission method of the embodiment of the invention can reduce the binding granularity of the binding feedback information sent by the user equipment to the network equipment.

Optionally, in the method S101 in this embodiment of the present invention, before dividing a subframe window corresponding to each carrier in the at least one carrier into at least one time domain window according to a preset time domain window subframe number if the total bit number of the feedback information of the at least one carrier is greater than a preset bit number, the method further includes:

s201a, obtaining the total bit number of the feedback information.

Specifically, the ue may determine the total bit number of the feedback information according to the number of downlink carriers of the ue, that is, the number of carriers of the at least one carrier, the number of subframes of a subframe window corresponding to each carrier, and a transmission mode of each carrier, for example.

Optionally, the obtaining of the total bit number of the feedback information in S201a may include:

Specifically, if the transmission mode of each carrier is a single-codeword transmission mode, and the ue receives one codeword on one subframe of each carrier, the ue has one bit of feedback information on one subframe of each carrier. If the number of subframes of the subframe window corresponding to each carrier is the same, the sum of the number of bits of the feedback information of the single codeword of the at least one carrier in the N subframes may be a product of the number of carriers of the at least one carrier and the number of subframes N. For example, if the number of the carriers of the at least one carrier is K and the number of subframes N of the subframe window corresponding to each carrier is N, the total number of bits of the feedback information may be K × N.

Optionally, if the transmission mode of each carrier is a single codeword transmission mode, the codeword feedback information includes feedback information of the single codeword. That is to say, the first binding feedback information may be information obtained by logically and-binding the feedback information of the single code words of all the subframes in each time domain window.

Alternatively, the obtaining of the total bit number of the feedback information in S201a may further include:

if the transmission mode of each carrier is a multi-code word transmission mode, performing logic and binding on feedback information of the multi-code words of each carrier in each subframe in a subframe window corresponding to each carrier to acquire second binding feedback information of each carrier in each subframe;

Specifically, if the transmission mode of each carrier is a multiple codeword transmission mode, and the ue receives multiple codewords on one subframe of each carrier, the ue has feedback information of multiple codewords on one subframe of each carrier. The feedback information of the multiple code words of each carrier in each subframe is logically and-bound, and actually, Spatial Bundling (SB) is performed on the feedback information of the multiple code words of each carrier in each subframe, so that the feedback information of multiple bits of the multiple code words of each carrier in each subframe becomes feedback information with one bit, that is, the second binding feedback information. If the number N of subframes in the subframe window corresponding to each carrier is the same, the sum of the bit numbers of the second binding feedback information of the at least one carrier in the N subframes may also be a product of the number N of carriers of the at least one carrier and the number N of subframes in the subframe window corresponding to each carrier. For example, if the number of the carriers of the at least one carrier is K and the number of the subframes of the subframe window corresponding to each carrier is N, the total number of bits of the feedback information may be K × N.

Optionally, if the transmission mode of each carrier is a multiple codeword transmission mode, the codeword feedback information includes the second bundling feedback information. That is to say, the first binding feedback information may be information obtained by first performing logical and binding on the feedback information of the multi-code word of each subframe in each time domain window to obtain the second binding feedback information, and then performing logical and binding on the second binding feedback information of all subframes in each time domain window.

if the transmission mode of a part of carriers in the at least one carrier is a multi-code word transmission mode, performing logic and binding on feedback information of the multi-code words of the part of carriers in each subframe in a subframe window corresponding to each carrier to acquire third binding feedback information of the part of carriers in each subframe;

determining the sum of the bit numbers of the third binding feedback information of the partial carriers in the subframe window corresponding to each carrier as a first bit number;

if the transmission mode of other carriers except the part of carriers in the at least one carrier is a single-code-word transmission mode, determining the sum of the bit numbers of the feedback information of the single code words of the other carriers in the subframe window corresponding to each carrier as a second bit number;

Specifically, the specific implementation processes of performing logic and binding on the feedback information of the multiple code words of the partial carriers in each subframe, obtaining third binding feedback information of the partial carriers in each subframe and determining the first bit number are similar to the case where the transmission mode of each carrier is a multiple code word transmission mode in the above embodiments of the present invention, and the difference is only that the number of carriers of the multiple code word transmission mode is different, and the similarities are not repeated here.

The specific implementation process of determining the second bit number according to the sum of the bit numbers of the feedback information of the single code words of the other carriers in the N subframes is similar to the case where the transmission mode of each carrier is a single code word transmission mode in the above embodiments of the present invention, and the difference is only that the number of carriers of the single code word transmission mode is different, and the similarities are not repeated here.

Optionally, if the transmission mode of the partial carrier is a multiple codeword transmission mode, the codeword feedback information of all subframes of the partial carrier in each time domain window corresponding to each carrier includes the third binding feedback information;

if the transmission mode of the other carrier is a single-codeword transmission mode, the codeword feedback information of all subframes of the other carrier in each time domain window corresponding to each carrier includes the feedback information of the single codeword.

Fig. 3 is a flowchart of another feedback information transmission method according to an embodiment of the present invention. As shown in fig. 3, before S101 divides a subframe window corresponding to each carrier in at least one carrier into at least one time domain window according to a preset time domain window subframe number in the above method according to an embodiment of the present invention, the method may further include:

s301, receiving time domain window binding indication information sent by the network equipment.

The network device may be the time domain window binding indication information sent after determining that the total bit number of the feedback information is greater than the preset bit number.

S302, according to the time domain window binding indication information and the corresponding relation between the time domain window binding indication information and the time domain window subframe number, determining the time domain window subframe number corresponding to the time domain window binding indication information as the preset time domain window subframe number.

The Time domain window bundling indication information may be, for example, Time-group bundling indication (TGBI) information. The network device sends the time domain window binding indication information to the user equipment through an independent message, and the user equipment may determine the time domain window binding indication information through a preset identifier or a preset bit value in the independent message. The network device may also carry the time domain window binding indication information and other information in a message and send the message to the user equipment. The user equipment may determine the time domain window binding indication information from the one message by a value of a preset identifier or a preset bit. Different time domain window binding indication information may be represented by different identifiers or different binary numbers. The corresponding relationship between the time domain window binding indication information and the time domain window subframe number may be, for example, a preset corresponding relationship table between the time domain window binding indication information and the time domain window subframe number, where in the corresponding relationship table between the time domain window binding indication information and the time domain window subframe number, one time domain window binding indication information has a corresponding time domain window subframe number, and different time domain window binding indication information may correspond to different time domain window subframe numbers.

For example, the table of correspondence between the time domain window binding indication information and the time domain window subframe number may be as shown in expression 1 below.

Time domain window binding indication information	Time domain window frame number
Time domain window binding indication information	Time domain window frame number	00	1
01	2	00	1
01	2	10	3
11	4	10	3

TABLE 1

If the time domain window binding indication information 00 exists, determining that the time domain window subframe number 1 corresponding to the time domain window binding indication information 00 in table 1 is 1 as the preset time domain window subframe number; if the time domain window binding indication information 01 exists, determining that the time domain window subframe number 2 corresponding to the time domain window binding indication information 01 in the table 1 is 2 as the preset time domain window subframe number; if the time domain window binding indication information 10 is found, the time domain window subframe number 3 corresponding to the time domain window binding indication information 10 determined in table 1 can be determined as the preset time domain window subframe number 3; if the time domain window binding indication information 11 is present, the time domain window subframe number 4 corresponding to the time domain window binding indication information 11, which can be determined by table 1, may be determined as the preset time domain window subframe number 4.

It should be noted that, in table 1, the number of time domain window subframes corresponding to each time domain window binding indication information may also be other values, which are only for illustration and are not sequentially taken as limitations in the embodiments of the present invention.

In the feedback information transmission method of fig. 2, the ue may obtain the time domain window subframe number by calculation. In the feedback information transmission method shown in fig. 3, the ue may determine the time window subframe number according to the indication information sent by the network device. That is, fig. 2 and fig. 3 are respectively a feedback information transmission method based on two parallel schemes for determining the time domain window subframe number.

Optionally, the sending the first binding feedback information to the network device in the first embodiment S103 may include:

and sending the first binding feedback information to the network equipment through PUCCH format 3.

According to the feedback information transmission method, by providing a plurality of schemes for determining the total bit number of the feedback information, the preset time domain window sub-frame number can be ensured to be more adaptive to the total bit number of the feedback information, the maximum bit number of feedback information sent by user equipment to network equipment is met, and the maximization of network capacity is ensured; meanwhile, a plurality of realizable schemes are provided through another method for determining the number of the preset time domain window subframes.

The embodiment of the invention also provides a feedback information transmission method. The method of the embodiments of the present invention may be performed by a network device. Fig. 4 is a flowchart of another feedback information transmission method according to an embodiment of the present invention. As illustrated in fig. 4, the method may include:

s401, receiving binding feedback information in each time domain window corresponding to each carrier in at least one carrier sent by user equipment if the total bit number of the feedback information of the at least one carrier is greater than a preset bit number; each time domain window corresponding to each carrier is a time domain window in at least one time domain window obtained by dividing a subframe window corresponding to each carrier by the user equipment according to a preset time domain window subframe number, wherein the preset time domain window subframe number is greater than or equal to 2; the binding feedback information is obtained by the user equipment performing logical and on the codeword feedback information of all subframes in each time domain window.

S402, determining the retransmission code word in the subframe window corresponding to each carrier according to the binding feedback information.
