To improve the data transmission rate, multiple carriers can be aggregated to provide a larger transmission bandwidth for data transmission by introducing Carrier Aggregation (CA) in the network system. The maximum number of aggregated carriers supported by the current user equipment is 5, and the maximum number of bits of feedback information for the 5 carriers supported by the user equipment on the Physical Uplink Control Channel (PUCCH) is limited.

The feedback information is logically and bound, and the feedback information bound to each carrier is sent to the network device in the uplink subframe corresponding to the subframe window, and the number of bits of the feedback information after each carrier binding is 1, thereby reducing the number of bits of feedback information sent to the network device.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The solution of the embodiments of the present invention is applicable to a scenario in which a user equipment and a network device transmit HARQ feedback information in a Long Term Evolution Advanced (LTE-A) system or a more advanced mobile communication system.

The embodiment of the invention provides a feedback information transmission method. The method can be performed by a user equipment. FIG. 1 is a flowchart of a method for transmitting feedback information according to an embodiment of the present invention. As shown in Figure 1, the method can include the following:

S101. If the total number of bits of the feedback information of the at least one carrier is greater than the preset number of bits, divide the subframe window corresponding to each carrier in the at least one carrier into at least one time domain window according to the preset number of time domain window subframes. 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 feedback information in a subframe window corresponding to each carrier in the at least one carrier. The total number of bits of the feedback information may be obtained by adding feedback information of the at least one carrier, where the feedback information of each carrier refers to feedback information in a subframe window corresponding to each carrier. The preset number of bits may be the maximum number of bits that the user equipment sends feedback information to the network device. The preset number of bits, for example, may be based on the user The maximum number of downlink carriers of the device, the maximum number of downlink subframes of the subframe window corresponding to each carrier, and the transmission mode of the user equipment. It should be noted that the user equipment can be in the CA scenario or in the non-CA scenario. If the user equipment is in the CA scenario, the at least one carrier may include at least two carriers. If the user equipment is in a non-CA scenario, the number of carriers of the at least one carrier may include one carrier.

The number of subframes included in the subframe window corresponding to each carrier may be the number of downlink subframes corresponding to each carrier determined by the user equipment according to the slot ratio corresponding to each carrier. The subframe window corresponding to each carrier may be a downlink subframe window composed of all downlink subframes corresponding to each carrier. The subframes of the different carriers in the at least one carrier may be the same or different, and the number of subframes of the subframes corresponding to different carriers in the at least one carrier may be the same or different. According to the preset number of time domain window subframes, the subframes corresponding to different carriers are divided, and the number of time domain windows corresponding to the different carriers obtained may be the same or different. Therefore, the at least one time domain window in which the subframe window corresponding to each carrier is divided according to the preset number of time domain window subframes may be a time domain window corresponding to each carrier.

In order to ensure the capacity of the network when the user equipment performs data transmission through the carrier aggregation of the at least one carrier, the time domain window may be divided only when the total number of bits of the feedback information is greater than the preset number of bits, that is, at least one carrier in S101 is executed. The step of dividing the subframe window corresponding to each carrier into at least one time domain window. Correspondingly, if the total number of bits of the feedback information is less than or equal to the preset number of bits, the solution of the embodiment of the present invention may not be performed, so that the at least one carrier is directly in the subframe window corresponding to each carrier. The feedback information is sent to the network device, so there is no problem of capacity loss due to an error in the binding feedback information.

That is, in S101 of the first embodiment of the present invention, the subframe window corresponding to each carrier in the at least one carrier is divided into at least one time domain window according to the preset number of time domain window subframes, which may be triggered in a preset manner. The condition is that the total number of bits of the feedback information is greater than the preset number of bits.

For example, if the number of aggregated carriers of the user equipment is k, that is, the number of carriers of the at least one carrier is K, where the number of codeword feedback information bits in the subframe window corresponding to the kth carrier may be

Then, the total number of bits of the feedback information of the at least one carrier in the subframe window corresponding to each carrier may be determined by the following formula (1).

In the formula (1), O _{SB is} the total number of bits of the feedback information, and K is the number of carriers of the at least one carrier, so K is greater than or equal to 1.

If the maximum number of bits of the feedback information sent by the user equipment to the network device is 20, that is, the preset number of bits is 20, the triggering condition for performing the feedback information transmission method in the embodiment of the present invention may be O _SB >20, according to the formula. (1) The total number of bits O _SB that can obtain the feedback information satisfies the trigger condition, that is, when the O _{SB is} greater than 20, the subframe window corresponding to each carrier may be divided into at least one time domain window; if the feedback information If the total number of bits O _SB does not satisfy the trigger condition, that is, when the O _{SB is} less than or equal to 20, the solution of the embodiment of the present invention may not be performed, and the at least one carrier is directly in the subframe window corresponding to each carrier. Feedback is sent to the network device.

The preset time domain window subframe number is the maximum number of subframes included in the unit time domain window. The subframe window corresponding to each carrier is divided according to the preset number of time domain window subframes, and may be a subframe window corresponding to each carrier by the time domain window in the preset time domain window subframe number The included subframes are divided 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 time domain window subframes. For example, if the number of subframes of the subframe window corresponding to each carrier is an integer multiple of the preset number of time domain window subframes, the number of subframes of each time domain window is equal to the preset time domain window. The number of frames. If the number of subframes of the subframe window corresponding to each carrier is not an integer multiple of the preset number of time domain window subframes, the number of subframes in the at least one time domain window having a time domain window is smaller than the preset. The number of time domain window subframes, and the number of subframes of the remaining time domain windows are equal to the preset number of time domain window subframes.

The number of the time domain window divided by the subframe window corresponding to each carrier may be smaller than each of the preset time domain window subframes. The number of subframes in the subframe window corresponding to the carrier.

S102. Acquire first binding feedback information of each carrier in the at least one carrier in each time domain window, where the first binding feedback information is a code of all subframes in each time domain window. The word feedback information is logically combined with the obtained binding information.

It is to be noted that, before the first binding feedback information of each carrier in each time domain window is obtained in S102, the method may further include:

Obtaining codeword feedback information in all subframes in each time domain window.

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

Performing the logical binding of the codeword feedback information in all the subframes in each time domain window to obtain the first binding feedback information, which may be performed by using the codeword feedback information in each time domain window. Time Bundling (TB) to obtain the first binding feedback information.

The number of bits of the codeword feedback information of all subframes in the subframe window corresponding to each carrier may be the number of subframes of the subframe window corresponding to each carrier. And logically binding the codeword feedback information of all the subframes in each time domain window of each carrier, and obtaining the first binding feedback information of each carrier in each time domain window. The number of bits of the feedback information of each carrier in the at least one time domain window may be the number of time domain windows corresponding to each carrier, that is, the time domain of the at least one time domain window. The number of windows. The number of the time domain window divided by the subframe window corresponding to each carrier may be smaller than each of the preset time domain window subframes. The number of subframes of the subframe window corresponding to the carrier. The first binding feedback information is information obtained by logically binding the codeword feedback information of all subframes in each time domain window, and the number of bits of the first binding feedback information may be smaller than each The number of bits of codeword feedback information for all subframes in the time domain window. Therefore, the embodiment of the present invention can reduce the number of bits of feedback information that the user equipment sends to the network device on the at least one carrier.

At the same time, the subframe window corresponding to each carrier is divided into at least one time domain window, so that the number of subframes in one time domain window corresponding to at least one carrier of the at least one carrier is smaller than the subframe window corresponding to the carrier. The number of subframes. The first binding feedback information is binding information obtained by logically combining the codeword feedback information of all subframes in each time domain window, and then acquiring each carrier in each time domain window. The first binding feedback information may also reduce the binding granularity of the binding feedback information sent to the network device on the at least one carrier. If the binding feedback information is in error, the codeword of each subframe in the time domain window of the binding feedback information is retransmitted, and the codewords of all the subframes are not required to be retransmitted, thereby reducing the binding feedback information. Loss of capacity.

The codeword feedback information of each subframe in each time domain window may be Hybrid Automatic Repeat ReQuest (HARQ) feedback information, such as Acknowledge (ACK) information or Negative acknowledgement (Negative). Acknowledge, referred to as NACK) information. The ACK information and the NACK information can be represented by 1 and 0, respectively. And the information obtained by logically and binding the codeword feedback information of all the subframes in each time domain window, that is, the first binding feedback information may be used to reduce the number of bits of the feedback information, and may also be used for Representing the codeword reception of each carrier within each time domain window.

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

S103. Send the first binding feedback information to the network device.

Specifically, the first binding feedback information is sent to the network device, and the first binding feedback information may be sent to the network device by using the PUCCH. Specifically, the first binding feedback information is sent to the network device, and the first binding feedback information may be sent to the network device by using the PUCCH in the uplink subframe corresponding to each time domain window.

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

The method for transmitting feedback information according to the first embodiment of the present invention, if the total number of bits of the feedback information of the at least one carrier is greater than the preset number of bits, each carrier of the at least one carrier may be corresponding according to the preset number of time domain window subframes. The sub-frame window is divided into at least one time domain window, the preset number of time domain window subframes is greater than or equal to 2; and the first binding feedback information of each carrier in each time domain window is obtained, the first The binding feedback information is binding information obtained by logically obtaining the codeword feedback information of all the subframes in each time domain window, and also sending the first binding feedback information to the network device. Due to the binding feedback information of each carrier, that is, the first binding feedback information is bound in each time domain window, the number of subframes of the time domain window corresponding to at least one carrier of the at least one carrier is smaller than The number of subframes of the subframe corresponding to the one carrier. Therefore, the method for transmitting feedback information in the first embodiment of the present invention can reduce the binding granularity of the binding feedback information, reduce the capacity loss caused by the binding feedback information, and improve the retransmission efficiency. .

In the meantime, the first binding feedback information is the binding information obtained by logically following the codeword feedback information of all the subframes in each time domain window, according to the feedback information transmission method in the first embodiment of the present invention. The binding feedback information may also reduce the number of feedback information bits sent to the network device on the at least one carrier, and transmit more feedback information of the carrier when the number of bits fed back by the user equipment is limited, thereby improving the user equipment. The actual number of aggregated carriers that can be supported to increase the data transmission rate.

The embodiment of the invention further provides a feedback information transmission method. FIG. 2 is a flowchart of another method for transmitting feedback information according to an embodiment of the present invention. As shown in FIG. 2, in the solution of the foregoing embodiment, before the subframe window corresponding to each carrier in the at least one carrier is divided into at least one time domain window according to the preset number of time domain window subframes, the method may further include:

S201: Round up the ratio of the total number of bits of the feedback information and the preset number of bits to determine the preset number of time domain window subframes.

Specifically, if the maximum number of bits of the feedback information sent by the user equipment to the network device is 20, that is, the preset number of bits is 20, and the total number of bits of the feedback information is 0 _SB , it may be a total bit according to the feedback information. The number O _SB and the preset number of bits 20 are the number of preset time domain window subframes determined by the following formula (2).

In formula (2), W _{TG is} the preset number of time domain window subframes. Since the size of the time domain window can be represented by the number of subframes of the time domain window, the W _TG is also the preset time domain window size. Then, the S101 may be configured to divide the subframe window corresponding to each carrier in the at least one carrier into at least one time domain window according to the preset time domain window subframe number W _TG . It should be noted that the user equipment may further determine the preset time domain window subframe according to the total number of bits of the feedback information and the preset number of bits, as long as the preset time domain window subframe is guaranteed. The number is greater than or equal to 2.

Assuming that the total number of bits O _SB of the feedback information is 40, according to the formula (2), the preset time domain window subframe number W _TG may be 2; if the total number of bits of the feedback information O _SB is 30, Then, according to the formula (2), the preset time domain window subframe number W _TG can be 2.

If the number of subframes of the subframe window corresponding to each carrier is N, at least one time domain window obtained by dividing the subframe window corresponding to each carrier according to the preset time domain window subframe number W _TG The number is M. Then, the preset time domain window subframe number W _TG , the subframe number N of the subframe window, and the time domain window number M can satisfy the following formula (3).

If the number of subframes N of the subframe window is an integer multiple of the preset number of time domain window subframes, the number of subframes of all the time domain windows in the M time domain windows corresponding to each of the divided carriers is equal to the number of subframes. The number of preset time domain window sub-frames. If the number of subframes N of the subframe is not an integer multiple of the preset number of time domain window subframes, the number of subframes of each time domain window corresponding to each of the divided carriers may be less than or equal to the preset. Time domain window The number of subframes, the number of subframes of the last time domain window in the time domain from the smallest to the largest in the M time domain windows corresponding to each carrier may be smaller than the preset number of time domain window subframes, and the remaining time domain windows The number of subframes is equal to the preset number of time domain window subframes.

For example, if the number of subframes N of the subframe window is an integer multiple of the preset number of time domain window subframes, the number of subframes of all time domain windows in the M time domain windows corresponding to each carrier is It is equal to the preset time domain window subframe number W _TG . Then, the codeword feedback information of each carrier in each time domain window is logically and bound, and the obtained first binding feedback information of each carrier in each time domain window may be, for example, Determined according to the following formula (4).

among them,

For the binding feedback information of the kth carrier in the mth time domain window, f{.} is a logical and binding function, where The codeword feedback information of each subframe of the mth time domain window of the kth carrier is sequentially. W _TG is the number of subframes of each time domain window, mW _TG , mW _TG +1, ... (m+1) W _TG -1 is the subframe W _{TG of} the mth time domain window in order. 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, then the kth obtained after logical and binding according to formula (4) Binding feedback information of the carrier in the mth time domain window

The number of bits can also be 1.

The number of feedback information bits of the kth carrier in the mth time domain window is

The number of bits, then the number of feedback information bits of the kth carrier in the M time domain window may be

The number of feedback information bits of the K carriers in the M time domain windows may be

The number of bits of the bit is 1, and the number of feedback information bits of the K carriers in the M time domain windows may be K*M. However, if the number of bits of the codeword feedback information of the k-th carrier in each subframe of the N subframes is 1, then the number of bits of the feedback information of the k-th carrier in the N subframes may be N, the K The total number of bits of feedback information of the carrier in N subframes may be K*N. It can be seen that the feedback information transmission method in the embodiment of the present invention can reduce the number of bits of feedback information sent by the user equipment to the network device.

It should be noted that, if the number of subframes N of the number of subframes is not an integer multiple of the preset number of time domain window subframes, the number of subframes of each time domain window corresponding to each carrier is less than or equal to the number of subframes. The number of preset time domain window sub-frames. For the time domain window in which the number of subframes is equal to the preset number of time domain window subframes, the codeword feedback information of each carrier in each time domain window is logically and bound, and the obtained each carrier is in the The first binding feedback information within each time domain window may be determined in a similar process as described in equation (4) above. For the time domain window in which the number of subframes is smaller than the preset number of time domain window subframes, the codeword feedback information of each carrier in each time domain window is logically and bound, and the obtained each carrier is in the The first binding feedback information in each time domain window may also be determined by a similar process as described in the above formula (4), except that the number of subframes of the bound time domain window is different from the above W _TG . The specific binding process is similar to the foregoing process in this embodiment, and details are not described herein again.

In addition, in the embodiment of the present invention, the codeword feedback information of all the subframes in each time domain window is bound to each carrier, and the binding is actually performed according to the size of each time domain window. In the embodiment, the binding granularity of the binding feedback information of each carrier in each time domain window may be the size of the divided time domain window, that is, the number of subframes of each time domain window. And the number of time domain window sub-frames after the partitioning is determined according to the preset number of time domain window subframes, and the time-domain window division corresponding to the subframe window corresponding to each carrier is determined, and thus, each time domain window The number of subframes is inevitably smaller than the number of subframes of the subframe window corresponding to each carrier. That is, the feedback information transmission method in the embodiment of the present invention can reduce the binding granularity of the binding feedback information sent by the user equipment to the network device.

Optionally, in the foregoing method S101, if the total number of bits of the feedback information of the at least one carrier is greater than the preset number of bits, the carrier corresponding to each carrier of the at least one carrier is configured according to the preset number of time domain window subframes. Before the sub-frame window is divided into at least one time domain window, the method further includes:

S201a. The total number of bits for obtaining the feedback information.

Specifically, the user equipment may be, for example, determined according to the number of downlink carriers of the user equipment, that is, the number of carriers of the at least one carrier, the number of subframes of the subframe window corresponding to each carrier, and the transmission mode of each carrier. The total number of bits of this feedback message.

Optionally, the total number of bits of the feedback information obtained by the S201a may include:

If the transmission mode of each carrier is a single codeword transmission mode, the sum of the number of bits of the feedback information of the single codeword of the at least one carrier in the subframe window corresponding to each carrier is determined as the feedback information. The total number of bits.

Specifically, if the transmission mode of each carrier is a single codeword transmission mode, and the user equipment receives one codeword in one subframe of each carrier, the user equipment has one subframe of each carrier. One bit of feedback information. 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 the number of carriers of the at least one carrier The product of the number of subframes N. For example, if the number of carriers of the at least one carrier is K, and the number of 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 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 codeword of all subframes in each time domain window.

Alternatively, the total number of bits of the feedback information obtained in the S201a may further include:

If the transmission mode of each carrier is a multi-codeword transmission mode, the feedback information of the multi-codeword in each subframe in each subframe corresponding to each carrier is logically and bound, and each is obtained. Second binding feedback information of the carriers in the each subframe;

The sum of the number of bits of the second binding feedback information of the at least one carrier in the subframe window corresponding to each carrier is determined as the total number of bits of the feedback information.

Specifically, if the transmission mode of each carrier is a multi-codeword transmission mode, the user equipment receives multiple codewords in one subframe of each carrier, and the user equipment is on one subframe of each carrier. Feedback information with multiple codewords. And logically binding the feedback information of the multi-codewords in each sub-frame of each carrier, which is actually performing spatial binding on the feedback information of the multi-codewords of each sub-frame in each sub-frame (Spatial Bundling) , referred to as SB), such that the feedback information of the multiple bits of the multi-codeword of each carrier in the each sub-frame becomes, and the feedback information with one bit is the second binding feedback information. If the number of subframes N of the subframe window corresponding to each carrier is the same, the sum of the number of bits of the second binding feedback information of the at least one carrier in the N subframes may also be the carrier of the at least one carrier. The number of products is the product of the number of subframes N of the subframe window corresponding to each carrier. For example, if the number of carriers of the at least one carrier is K, and the number of subframes corresponding to the subframe window of 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 multi-codeword transmission mode, the codeword feedback information includes the second binding feedback information. That is, the first binding feedback information may first logically and bind the feedback information of the multiple codewords of each subframe in each time domain window to obtain the second binding feedback information, and then each of the The second binding feedback information of all subframes of the time domain window is logically and information obtained after binding.

If the transmission mode of the partial carrier in the at least one carrier is a multi-codeword transmission mode, the feedback information of the multi-codeword in each subframe in the subframe window corresponding to each carrier is logically and bound, and the a third binding feedback information of the partial carrier in each of the subframes;

The number of bits of the third binding feedback information of the partial carrier in the subframe window corresponding to each carrier And the sum is determined as the first number of bits;

If the transmission mode of the other carriers other than the part of the at least one carrier is a single codeword transmission mode, the sum of the number of bits of the feedback information of the single codeword in the subframe window corresponding to the other carrier is determined. Is the second number of bits;

The sum of the first bit number and the second bit number is determined as the total number of bits of the feedback information.

Specifically, the feedback information of the multi-codeword in the sub-frame is logically and bound to obtain the third binding feedback information of the part of the carrier in each sub-frame and the first bit number is determined. The specific implementation process is similar to the case where the transmission mode of each carrier in the foregoing embodiment of the present invention is a multi-codeword transmission mode. The only difference is that the number of carriers in the multi-codeword transmission mode is different, and the similarities are not here. Let me repeat.

The specific implementation process of determining the second bit number according to the sum of the number of bits of the feedback information of the single codeword of the other carriers in the N subframes is the same as the transmission mode of each carrier in the foregoing embodiment of the present invention. The case of the codeword transmission mode is similar. The only difference is that the number of carriers in the single codeword transmission mode is different, and the similarities are not described herein.

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

FIG. 3 is a flowchart of still another method for transmitting feedback information according to an embodiment of the present invention. As shown in FIG. 3, in the foregoing method, in the foregoing method, S101 may further divide a subframe window corresponding to each carrier in at least one carrier into at least one time domain window according to a preset number of time domain window subframes, where the method may further include:

S301. Receive time domain window binding indication information sent by the network device.

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

S302. Determine, according to the time domain window binding indication information and the correspondence between the time domain window binding indication information and the number of time domain window subframes, the number of time domain window subframes corresponding to the time domain window binding indication information as the pre Set the number of time domain window sub-frames.

The time domain window binding indication information, for example, may be a time domain grouping binding indication (Time-group Bundling indication (TGBI) information. The network device sends the time domain window binding indication information to the user equipment by using an independent message, where the user equipment may determine the time domain window binding indication information by using 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 using a preset identifier or a value of 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 number of time domain window subframes may be, for example, a preset relationship table between the preset time domain window binding indication information and the number of time domain window subframes, where the time domain window binding indication information is In the correspondence table with the number of time domain window subframes, one time domain window binding indication information has a corresponding number of time domain window subframes, and different time domain window binding indication information may correspond to different time domain window subframe numbers.

For example, the correspondence table between the time domain window binding indication information and the number of time domain window subframes may be represented by 1 as follows.

时域窗绑定指示信息Time domain window binding indication information	时域窗子帧数Time domain window subframe number
