Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

The data transmission method based on the code block group provided by the embodiment of the invention can be applied to communication systems such as 5G/LTE and the like which introduce NR technology, and persons skilled in the art can understand that the embodiment is not limited by 5G/LTE. In some communication systems, for example, in a communication system such as 5G/LTE that introduces NR technology, because any one grant-sending timeslot in a bundling window may transmit multiple TBs, and the numbers of CBGs included in the TBs in different grant-sending timeslots may be different, when a user equipment forms response information for a CBG sent by a network side through the grant-sending timeslot in the bundling window and sends the response information to the network side, if bits included in the response information are determined according to the maximum number of CBGs included in the grant-sending timeslot, waste of uplink transmission resources is often caused.

According to the method and the device, the code block group quantity information is set in the authorization aiming at the user equipment, and the authorization is sent to the user equipment, so that the user equipment can know the bit of the code block group corresponding response information which is actually sent through the time slot for sending the authorization in the binding window according to the code block group quantity information in the authorization, and the method and the device are favorable for guaranteeing the reliability of data transmission and avoiding the phenomenon of uplink transmission resource waste.

Fig. 1 is a flowchart illustrating an embodiment of a method for transmitting data based on a code block group according to the present application. As shown in fig. 1, the method of this embodiment includes: step S100 and step S110.

S100, setting code block group quantity information in authorization for user equipment.

In an optional example, a network side (e.g., a network device such as an eNodeB) in the present application may send a code block group to a user equipment through one or more time slots in a bundling window (bundling window) for sending a grant. The binding window in this application can be considered as: for a ue, when an uplink timeslot is bound with a plurality of downlink timeslots, all downlink timeslots in the binding may be regarded as a window, which is a binding window. The bundling window shown in fig. 2 includes 4 slots (i.e., downlink slots), which are the 1 st slot (i.e., the slot with DAI _ C ═ 0 in fig. 2), the 2 nd slot (i.e., the slot with DAI _ C ═ 1 in fig. 2), the 3 rd slot (i.e., the slot with DAI _ C ═ 2 in fig. 2), and the 4 th slot (i.e., the slot with DAI _ C ═ 3 in fig. 2), respectively. The network side can actually send the code block group by utilizing partial time slots in the binding window according to the actual code block group sending requirement; the network side may also actually transmit the code block group using all timeslots within the bundling window. The time slots in which the code block groups are actually transmitted are provided with grants, hereinafter referred to as time slots in which grants are transmitted.

In an alternative example, the time slots within the bundling window in which the grant is sent may each further include a PDSCH (Physical Downlink Shared Channel), and each PDSCH within the bundling window may be used for transmitting one or more code block groups.

In an alternative example, the code block group number information represents the number of code block groups transmitted to the user equipment within the bundling window, and it can also be considered that the code block group number information may represent the sum of the number of code block groups respectively transmitted to the user equipment through each authorized time slot within the bundling window. One of the code block group quantity information functions is bits for indicating that the user equipment corresponds to the response information for the code block groups in the bundling window, in other words, one of the code block group quantity information functions is bits for indicating that the user equipment actually forms the response information for the code block groups respectively contained in each time slot of each transmission authorization in the bundling window. The response message may be a/N (Ack/Nack), in which case 1 bit of the response message corresponds to one code block group transmitted. In a specific example, for the bundling window 200 shown in fig. 2, a first authorized transmission timeslot in the bundling window includes 8 code block groups, a second authorized transmission timeslot includes 3 code block groups, a third authorized transmission timeslot includes 2 code block groups, a fourth authorized transmission timeslot includes 4 code block groups, and the 4 authorized transmission timeslots in the bundling window include 17 code block groups in total, so that the user equipment should form the response message with 17 bits for each code block group actually included in each authorized transmission timeslot in the bundling window, and the code block group included in the first authorized transmission timeslot corresponds to the highest 8 bits (i.e., 0 th bit to 7 th bit) in the response message, the code block group included in the second authorized transmission timeslot corresponds to the 8 th bit to 10 th bit in the response message, the code block included in the third authorized transmission timeslot corresponds to the 11 th bit to 12 th bit in the response message, the fourth transmission-authorized slot contains a code block group corresponding to bits 13 to 16 in the response information. Those skilled in the art will understand that the time slot for sending the grant may be a partial time slot in the binding window, for example, the first time slot for sending the grant in the binding window includes 8 code block groups, the second time slot does not send the grant, the third time slot, i.e., the time slot for sending the grant, includes 2 code block groups, the fourth time slot, i.e., the time slot for sending the grant, includes 4 code block groups, the 3 time slots for sending the grant in the binding window collectively include 12 code block groups, and the rest of the settings are the same as above, and are not described again for brevity.

Because code block groups actually contained in different time slots in the binding window may be different, if bits contained in response information corresponding to each time slot for sending authorization are determined according to the maximum number of CBGs contained in all time slots in the binding window, a phenomenon of reserving bits for nonexistent code block groups often occurs, thereby causing waste of uplink transmission resources. The code block group quantity information in the application can indicate bits required for forming response information for code block groups actually contained in each time slot for sending authorization in the binding window, so that the application can effectively avoid the phenomenon of uplink transmission resource waste.

In an alternative example, the code block group number information may be implemented in various ways, and three specific examples are described below:

as a first specific example, the code block group number information in the present application may include: setting the cumulative number of code block groups and the total number of the code block groups, wherein a binding window comprises m time slots, and for a time slot n for sending authorization, the cumulative number of the code block groups indicates the sum of the number of the code block groups from the 1 st time slot for sending authorization to the time slot n for sending authorization, wherein n and m are positive integers, and n is less than or equal to m; the total number of code block groups represents the sum of the number of code block groups contained in the time slot in which the grant is transmitted within the bundling window. In other words, the above-mentioned cumulative number of code block groups indicates the number of all code block groups respectively included from the 1 st transmission grant slot in the bundling window to each transmission grant slot in the bundling window.

As a second specific example, the code block group number information in the present application may include: setting the cumulative number of code block groups and the total number of the code block groups, wherein the bundling window comprises m time slots, and for the time slot N for transmitting the authorization, the cumulative number of the code block groups represents the sum of the number of the code block groups from the 1 st time slot for transmitting the authorization to the time slot N for transmitting the authorization, wherein in the case of the semi-statically configured PDSCH, the time slot without transmitting the authorization can transmit TB, and in the feedback of A/N, the A/N bit of the semi-statically configured PDSCH is attached before or after the A/Nbit of the total CBG. For other grants without corresponding data transmission, the cumulative CBG number does not increase. Wherein n and m are positive integers, and n is less than or equal to m; in this case, the total number of code block groups represents the sum of the number of code block groups included in the time slot within the bundling window.

This specific example will be described below with reference to fig. 2. In fig. 2, a transmission grant timeslot with DAI _ C ═ 0 includes 8 code block groups, a transmission grant timeslot with DAI _ C ═ 1 includes 3 code block groups, a timeslot with DAI _ C ═ 2 includes 2 code block groups, and a transmission grant timeslot with DAI _ C ═ 3 includes 4 code block groups, and under the setting, the cumulative number of code block groups is specifically: 8. 11, 13 and 17, the total number of code block groups is 17, and both the cumulative number of code block groups and the total number of code block groups can be represented by 5 bits (bit). The second specific example is the same, and for brevity, will not be described again.

In a third specific example, the code block group number information in the present application may include: setting a code block group accumulated quantity range and a residual value, wherein the binding window comprises m time slots, and for a time slot n with authorization to send, the code block group accumulated quantity range represents a value interval to which the sum of code block group accumulated quantities contained in the time slot with authorization to send is from the 1 st time slot with authorization to the time slot n with authorization to send, and the value span of the value interval can be the maximum code block group quantity contained in one time slot, for example, if one time slot contains 8 code block groups at most, the value span of the value interval is 8; the residual value is a value obtained by modulo (mod) operation of the total number of the code block groups and the number of the code block groups which are contained in one time slot in the binding window at most. It can also be considered that the above-mentioned code block group cumulative number range represents a value range to which the number of all code block groups included in the value range from the 1 st timeslot to each authorized transmission timeslot in the binding window respectively belongs; the value interval can be expressed as: n × M +1, (N +1) × M ], where M is the maximum number of code block groups that a timeslot can contain (e.g., 8 code block groups), N is the number of all code block groups that a timeslot N contains, starting from the 1 st timeslot in the bundling window and ending until the timeslot N in the bundling window where a transmission grant is sent, divided by the next value (e.g., 0, 1, 2, or 3) of the quotient of M, that is, a modulo value. This specific example is explained below with reference to fig. 2.

Setting the bundling window in fig. 2 to include four time slots, where each time slot may include at most 8 code block groups, the value interval of the cumulative number range of the code block groups may be represented by 2 bits, 00 represents that the value interval of the cumulative number range of the code block groups is 1 to 8, 01 represents that the value interval of the cumulative number range of the code block groups is 9 to 16, 10 represents that the value interval of the cumulative number range of the code block groups is 17 to 24, and 11 represents that the value interval of the cumulative number range of the code block groups is 25 to 32. The remainder may be represented in 3 bits. In addition, under the condition that the bundling window includes four time slots, each time slot may include 6 code block groups at most, the range of the cumulative number of the code block groups may be represented by 2 bits, 00 represents that the value interval of the range of the cumulative number of the code block groups is 1 to 6, 01 represents that the value interval of the range of the cumulative number of the code block groups is 7 to 12, 10 represents that the value interval of the range of the cumulative number of the code block groups is 13 to 18, and 11 represents that the value interval of the range of the cumulative number of the code block groups is 19 to 24. The remainder may be represented in 3 bits.

In an alternative example, the authorization for the user equipment in the present application may include: the downlink grant for the ue, for example, the downlink grant corresponding to each timeslot for sending the grant in the bundling window. The authorization for the user equipment in the present application may also include: the uplink grant for the ue, for example, the uplink grant corresponding to each timeslot for sending the grant in the bundling window is unified. Authorization for the user device may also include both: the downlink grant corresponding to each time slot for sending the grant in the binding window may further include: and unifying the corresponding uplink authorization in each time slot for sending the authorization in the binding window. According to the method and the device, the code block group quantity information is arranged in the downlink authorization corresponding to each time slot of the sending authorization in the binding window and the uplink authorization corresponding to each time slot of the sending authorization in the binding window, so that the phenomenon that the number of bits required by the downlink authorization or the uplink authorization is too much due to the fact that the code block group quantity information is arranged in the downlink authorization or the uplink authorization in a centralized manner can be avoided.

In one optional example, the code block group number information in the present application includes: in the case that the ue transmits the response information for the code block group by using a Physical Uplink Control Channel (PUCCH), the cumulative number of code block groups and the total number of code block groups may be set in the downlink grant of each grant-sending timeslot. This alternative example is described below in conjunction with fig. 2. Setting the bundling window shown in fig. 2 to include 4 timeslots, and each of the 4 timeslots is a grant transmission timeslot, each grant transmission timeslot includes at most 8 code block sets, where a grant transmission timeslot with DAI _ C ═ 0 (i.e., a box with shading being a circular dot in fig. 2) includes 8 code block sets, a grant transmission timeslot with DAI _ C ═ 1 (i.e., a box with shading being a downward-right oriented stripe in fig. 2) includes 3 code block sets, a grant transmission timeslot with DAI _ C ═ 2 (i.e., a box with shading being a vertical stripe in fig. 2) includes 2 code block sets, and a grant transmission timeslot with DAI _ C ═ 3 (i.e., a box with shading being a downward-left oriented stripe in fig. 2) includes 4 code block sets; under the above setting, the code block group cumulative number and the code block group total number in the downlink grant of the transmission grant timeslot with DAI _ C ═ 0 are 00111 and 10001, respectively, the code block group cumulative number and the code block group total number in the downlink grant of the transmission grant timeslot with DAI _ C ═ 1 are 01010 and 10001, respectively, the code block group cumulative number and the code block group total number in the downlink grant of the transmission grant timeslot with DAI _ C ═ 2 are 01100 and 10001, respectively, and the code block group cumulative number and the code block group total number in the downlink grant of the transmission grant timeslot with DAI _ C ═ 3 are 10001 and 10001, respectively. In addition, in this optional example, the downlink grants of the 4 slots of sending grants may further include a slot count value of the sending grant in the bundling window and a total number of slots of the sending grant in the bundling window, for example, the downlink grant of the first slot of sending grant includes 00 (slot count value) and 11 (total number of slots), so as to indicate that the downlink grant is a downlink grant of the slot of the first sending grant in the bundling window, and the bundling window includes 4 slots of sending grants; the downlink grant of the time slot of the second sending grant comprises 01 (time slot count value) and 11 (time slot total number) to indicate that the downlink grant is the downlink grant of the time slot of the second sending grant in the binding window, and the binding window comprises 4 time slots of the sending grants; the downlink grant of the third time slot for sending the grant comprises 10 (time slot count value) and 11 (time slot total number) to indicate that the downlink grant is the downlink grant of the third time slot for sending the grant in the binding window, and the binding window comprises 4 time slots for sending the grant; the downlink grant of the time slot of the fourth transmission grant includes 11 (time slot count value) and 11 (total number of time slots), to indicate that the downlink grant is a downlink grant of the time slot of the fourth transmission grant in the bundling window, and the bundling window includes 4 time slots of the transmission grant.

In one optional example, the code block group number information in the present application includes: in the case that the user equipment transmits response information for the code block group by using a Physical Uplink Shared Channel (PUSCH), the code block group cumulative number and the code block group total number may be respectively set in the downlink grant of each grant transmission time slot and the Uplink grant corresponding to each grant transmission time slot in the binding window. This alternative example is described below in conjunction with fig. 2. The bundling window shown in fig. 2 is configured to include 4 slots for transmitting grants, and each slot for transmitting grants includes at most 8 code block groups, wherein the time slot for the transmission grant of DAI _ C ═ 0 contains 8 code block groups, the time slot for the transmission grant of DAI _ C ═ 1 contains 3 code block groups, the time slot for the transmission grant of DAI _ C ═ 2 code block groups, the time slot for the transmission grant of DAI _ C ═ 3 contains 4 code block groups, under this setting, the cumulative number of code block groups in the downlink grant of the transmission grant slot with DAI _ C ═ 0 may be 00111, the cumulative number of code block groups in the downlink grant of the transmission grant slot with DAI _ C ═ 1 may be 01010, the cumulative number of code block groups in the downlink grant of the transmission grant slot with DAI _ C ═ 2 may be 01100, and the cumulative number of code block groups in the downlink grant of the transmission grant slot with DAI _ C ═ 3 may be 10001. The total number of code block groups in the uplink grant corresponding to each time slot for transmitting the grant in the bundling window may be 10001. In addition, in this optional example, the downlink grants of the 4 slots with transmission grants may further include a slot count value of the transmission grant in the bundling window and a total number of slots with transmission grants in the bundling window, for example, the downlink grant of the first slot with transmission grant includes 00 bits of 2 to indicate that the downlink grant corresponds to the slot with transmission grant of DAI _ C ═ 0, the downlink grant of the second slot with transmission grant includes 01 bits of 2 to indicate that the downlink grant corresponds to the slot with transmission grant of DAI _ C ═ 1, the downlink grant of the third slot with transmission grant includes 10 bits of 2 to indicate that the downlink grant corresponds to the slot with transmission grant of DAI _ C ═ 2, the downlink grant of the fourth slot with transmission grant includes 11 bits of 2 to indicate that the downlink grant corresponds to the slot with transmission grant of DAI _ C ═ 3, in addition, the downlink grant of each slot for transmitting the grant also includes 11 bits of 2 bits, respectively, to indicate that the slot including 4 slots for transmitting the grant is included in the bundling window.

In one optional example, the code block group number information in the present application includes: the method and the device have the advantages that the code block group accumulated quantity range and the residual value can be respectively arranged in the downlink authorization of each authorized time slot and the uplink authorization corresponding to each authorized time slot in the binding window in a unified manner under the condition that the user equipment transmits the response information aiming at the code block group by using the PUSCH. This alternative example is described below in conjunction with fig. 2.

Setting the bundling window shown in fig. 2 to include 4 slots for transmitting grants, and each slot for transmitting grants may include 8 code block groups at most, where the slot for transmitting grants with DAI _ C ═ 0 includes 8 code block groups, the slot for transmitting grants with DAI _ C ═ 1 includes 3 code block groups, the slot for transmitting grants with DAI _ C ═ 2 includes 2 code block groups, and the slot for transmitting grants with DAI _ C ═ 3 includes 4 code block groups; under this setting, the code block group cumulative number range in the downlink grant of the transmission grant time slot with DAI _ C ═ 0 may be 00, the code block group cumulative number range in the downlink grant of the transmission grant time slot with DAI _ C ═ 1 may be 01, the code block group cumulative number range in the downlink grant of the transmission grant time slot with DAI _ C ═ 2 may be 01, and the code block group cumulative number range in the downlink grant of the transmission grant time slot with DAI _ C ═ 3 may be 10. The remaining value of the uplink grant corresponding to each time slot for sending the grant in the bundling window may be 000. In addition, in this optional example, the downlink grants of the 4 slots of the transmission grant may further include a slot count value of the transmission grant in the bundling window and a total number of slots of the transmission grant in the bundling window, which are described in the foregoing embodiment specifically, and a description thereof is not repeated here.

In an alternative example, the present application may scramble the code block group number information set in the grant, for example, scramble the code block group number information with RNTI (Radio Network temporary Identity). More specifically, the present application may use 4 different RNTIs to perform scrambling characterization on different states represented by the range of the cumulative number of code block groups of 2 bits, respectively, and may use 16 different RNTIs to perform scrambling characterization on different states represented by the remainder of 3 bits, respectively. The present application does not limit the specific implementation of scrambling the code block group number information set in the grant.

And S110, sending the authorization and the code block group to user equipment.

In an optional example, the present application may send, to the user equipment, a downlink grant corresponding to each time slot for sending the grant in the binding window, and an uplink grant corresponding to each time slot for sending the grant in the binding window in a unified manner, and send all the code block groups to the user equipment through each time slot for sending the grant in the binding window.

Fig. 3 is a flowchart of another embodiment of the data transmission method based on the code block group according to the present application. As shown in fig. 3, the method of this embodiment mainly includes: step S300 and step S310.

S300, decoding the received authorization aiming at the user equipment to acquire code block group quantity information.

In an optional example, the information about the number of code block groups may be obtained from a decoded result by decoding a downlink grant corresponding to each time slot for sending a grant in a received bundling window. The method and the device can also decode the downlink grant corresponding to each time slot for sending the grant in the received binding window and the uplink grant corresponding to each time slot for sending the grant in a unified manner, so as to obtain the information of the number of the code block groups from the decoded result. The application also does not exclude the situation that the information of the number of the code block groups is obtained from the decoded result by decoding the uplink grant uniformly corresponding to each time slot for sending the grant in the received binding window.

In an alternative example, the code block group number information obtained from the decoded result may be specifically the code block group cumulative number and the code block group total number, and may also be specifically the code block group cumulative number range and the remainder.

In a specific example, when the user equipment transmits the response information to the network side based on the PUCCH, the present application may respectively decode downlink grants corresponding to respective transmission granted time slots in the received bundling window (for example, respectively decode downlink grants corresponding to respective 4 time slots in fig. 2), so as to obtain downlink grants corresponding to respective decoded transmission granted time slots, and the present application may respectively obtain the cumulative number of code block groups and the total number of code block groups from each decoded downlink grant.

For another specific example, in a case that the user equipment transmits the response information to the network side based on the PUSCH, the present application may obtain the downlink grants corresponding to the decoded transmission granted time slots by decoding the downlink grants corresponding to the received transmission granted time slots in the bundling window (for example, decoding the downlink grants corresponding to the 4 time slots in fig. 2, respectively), and the present application may obtain the cumulative number of code block groups from each decoded downlink grant (for example, obtain the cumulative number of 2, 3, or 4 code block groups), and the present application may obtain the total number of code block groups from the decoded uplink grant result by decoding the uplink grants corresponding to the received transmission granted time slots in the bundling window.

In another specific example, when the user equipment transmits the response information to the network side based on the PUSCH, the present application may obtain the downlink grants corresponding to the decoded transmission granted time slots by decoding the downlink grants corresponding to the received transmission granted time slots in the bundling window, respectively obtain the cumulative number range of the code block groups from each decoded downlink grant, and decode the uplink grants corresponding to the received transmission granted time slots in the bundling window in a unified manner, so that the present application may obtain the remaining value from the decoded uplink grant result.

S310, determining the bit of the response information corresponding to the code block group in the binding window according to the code block group quantity information.

In an alternative example, the application may determine, according to the code block group number information, bits required to form response information for code block groups contained in respective transmission-authorized time slots within the bundling window. The response information in this application may be an a/N (Ack/Nack), and in a general case, 1 bit in the response information corresponds to one code block group, and if a downlink grant of one grant sending time slot is lost, all code block groups included in the grant sending time slot are also lost. The corresponding bit in the response information corresponding to each of all missing code block groups is set to a value representing n (nack), such as 1/0. If the downlink grant of a time slot for sending the grant is not lost, the ue will successfully receive all the code block groups included in the time slot for sending the grant. The ue checks all code block groups that it successfully receives, and if any code block group is successfully checked, the corresponding bit in the response information corresponding to the code block group is set to a value representing Ack, for example, set to 0/1, and if any code block group is unsuccessfully checked, the corresponding bit in the response information corresponding to the code block group is set to a value representing n (nack), for example, set to 1/0. The specific implementation mode for checking the code block group is not limited in the application.

In an optional example, in a case that the obtained number information of the code block groups is specifically the cumulative number of the code block groups and the total number of the code block groups, the bit of the response information corresponding to all the code block groups in the bundling window may be determined according to the total number of the received code block groups, that is, the bit required by the response information of all the code block groups included in all the time slots for sending the grant in the bundling window may be determined according to the total number of the received code block groups. The number of code block groups contained in the time slot for sending the authorization corresponding to the lost at least one downlink authorization can be determined according to the received cumulative number of the code block groups and the total number of the code block groups, that is, the corresponding bits in the response information corresponding to the lost code block groups can be determined according to the received cumulative number of the code block groups and the total number of the code block groups. This alternative example is described below in conjunction with fig. 2. Setting the bundling window shown in fig. 2 to include 4 slots with transmission grants, namely, a slot with transmission grant DAI _ C equal to 0, a slot with transmission grant DAI _ C equal to 1, a slot with transmission grant DAI _ C equal to 2, and a slot with transmission grant DAI _ C equal to 3, and setting that the downlink grants corresponding to the slot with transmission grant DAI _ C equal to 1 and the slot with transmission grant DAI _ C equal to 3 are all lost, the present application obtains the total number of code block groups and the total number of code block groups as 00111 and 10001 by decoding the downlink grant of the slot with transmission grant DAI _ C equal to 0, and obtains the total number of code block groups and the total number of code block groups as 01100 and 10001 by decoding the downlink grant of the slot with transmission grant DAI _ C equal to 2. Since the total number of the code block groups obtained by decoding is 10001, the application can determine that 17-bit response information needs to be formed; since the cumulative number of code block groups obtained by decoding the downlink grant of the time slot in which the DAI _ C is 0, is 00111, it can be known that the first 8 bits of the 17 bits correspond to 8 code block groups included in the time slot in which the DAI _ C is 0; since the cumulative number of code block groups obtained by decoding the downlink grant of the slot in which the DAI _ C-2 transmission grant is transmitted is 10001, 5 code block groups included in the slot in which the DAI _ C-1 and DAI _ C-2 transmission grants correspond to the 9 th bit to the 13 th bit in the 17-bit response information can be known; the user equipment receives all code block groups contained in the time slot with the DAI _ C-2 according to the downlink grant of the time slot with the DAI _ C-2 transmission grant, and since the time slot with the DAI _ C-2 transmission grant contained in the time slot with the DAI _ C-2 transmission grant contains 2 code block groups, the user equipment can determine that the downlink grant of the time slot with the DAI _ C-1 transmission grant is lost, the number of the code block groups contained in the time slot with the DAI _ C-1 transmission grant lost is 3, and the 9 th to 11 th bits in the 17-bit response information should be set to be a value representing Nack. Since the total number of code block groups obtained by decoding is 10001, and the cumulative number of code block groups obtained by decoding the downlink grant of the time slot with the transmission grant of DAI _ C _ 2 is 10001, the user equipment may determine that 4 code block groups are lost after the time slot with the transmission grant of DAI _ C _ 2, and the last 4 bits in the 17-bit response information should be set to a value representing Nack. As can be seen from the above description, even when a partial authorization is lost, the technical solution provided in the present application may still enable the ue to determine, according to the received partial authorization, the bit of the response message corresponding to the code block group actually included in the time slot for sending the authorization in the binding window, so as to avoid the phenomenon that the corresponding bit is reserved for the code block group not actually included in the time slot for sending the authorization in the response message.

The above description of the optional example with reference to fig. 2 may also be applied to an application scenario in which the cumulative number of code block groups is obtained from the downlink grants respectively corresponding to the time slots for sending the grants, and the total number of code block groups is obtained from the uplink grants. The description will not be repeated here.

In an optional example, in a case that the obtained code block group quantity information is specifically a code block group cumulative quantity range and a residual value, the application may determine, according to the received code block group cumulative quantity range and the residual value, bits of the response information corresponding to all code block groups in the bundling window and bits of the response information corresponding to the lost code block group. That is to say, the present application may determine, according to the received code block group cumulative number range and the residual value, bits required for response information of all code block groups included in all time slots of transmission authorization within the bundling window, and corresponding bits in response information corresponding to code block groups included in time slots of transmission authorization corresponding to at least one lost downlink authorization. This alternative example is described below in conjunction with fig. 2. The bundling window shown in fig. 2 is configured to include 4 slots for transmission grants, namely, a slot for transmission grant with DAI _ C being 0, a slot for transmission grant with DAI _ C being 1, a slot for transmission grant with DAI _ C being 2, and a slot for transmission grant with DAI _ C being 3, respectively, and a downlink grant corresponding to the slot for transmission grant with DAI _ C being 3 is lost. By decoding the downlink grant of the time slot in which the transmission grant with DAI _ C ═ 0 is transmitted, the cumulative number range of the obtained code block groups is 00 (representing 1 to 8); decoding a downlink grant of a time slot in which the transmission grant with DAI _ C ═ 1, so as to obtain a code block group accumulation number range of 01 (indicating that a value interval is 9-16); by decoding the downlink grant of the time slot in which the transmission grant of DAI _ C ═ 2 is transmitted, the cumulative number of code block groups obtained is in the range of 01 (indicating that the value interval is 9 to 16). By decoding the uplink grant, the remainder is obtained as 000. Since the present application may obtain the total number of timeslots of the transmission grant in the bundling window from any received downlink grant (e.g. 4), and the received timeslot count value DAI _ C in the first downlink grant is 0, the timeslot count value DAI _ C in the second downlink grant is 1, and the timeslot count value DAI _ C in the third downlink grant is 2, the present application may determine that the downlink grant corresponding to the timeslot of the transmission grant with DAI _ C — 3 is lost. Since the remainder obtained by the ue decoding the uplink grant is 000, the ue receives 8 code block groups included in the slot authorized to transmit DAI _ C ═ 0 by the downlink grant of the slot authorized to transmit DAI _ C ═ 0, receives 3 code block groups included in the slot authorized to transmit DAI _ C ═ 1 by the downlink grant of the slot authorized to transmit DAI _ C ═ 1, receives 2 code block groups included in the slot authorized to transmit DAI _ C ═ 2 by the downlink grant of the slot authorized to transmit DAI _ C ═ 2, and has a cumulative number of code block groups in the downlink grant of the slot authorized to transmit DAI _ C ═ 2 ranging from 01 (indicating that the value range is 9-16), 8+3+2>9+0 (the remainder 000 indicating 0), the ue can conclude that the cumulative number of code block groups in the slot authorized to transmit DAI _ C ═ 3 should be 10-17 (indicating that the cumulative number of code block should be 10-17) Since the remaining value obtained by decoding the uplink grant by the ue is 000, the ue may conclude that 17 bits of response information need to be formed. Since 13 code block groups have been received, it can be determined that the number of code block groups included in the slot in which the transmission grant of the missing DAI _ C — 3 is authorized should be 4, and the last 4 bits in the 17-bit response message should be set to the value representing Nack.
