Description

Method, terminal and base station for transmitting HARQ feedback information

Divisional application statement

The invention provides a divisional application of Chinese patent application named 'method, terminal and base station for transmitting HARQ feedback information' based on application number 201880001486.7 and application date of 2018, 07-25.8.

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, a terminal, and a base station for transmitting HARQ feedback information.

Background

With the development of the internet of things, MTC (Machine Type Communication), i.e., a Communication technology between machines without human interference, is widely applied to smart cities, such as meter reading, as a typical representative of cellular internet of things technology; intelligent agriculture, such as acquisition of information of temperature and humidity; intelligent transportation such as sharing a single vehicle.

In the related art, the scheduling of radio resources by the MTC FDD (Frequency Division duplex) system is as follows: an MPDCCH (MTC Physical Downlink Control Channel) schedules a PDSCH (Physical Downlink Shared Channel) or a PUSCH (Physical Uplink Shared Channel). The MTC terminal needs to receive and blindly detect the MPDCCH before receiving or sending data. For the case that a large data packet needs to be sent to the MTC terminal, the data packet needs to be scheduled for several rounds. In most cases, due to similar channel conditions, the scheduling contents of several MPDCCH are similar. Even in this case, the terminal still needs to demodulate the MPDCCH scheduled each time, resulting in excessive power consumption.

In order to avoid the power consumption in the above situation, the related art proposes a scheme in which one MPDCCH schedules a plurality of uplink or downlink TBs (Transmission block data blocks). How to perform HARQ (Hybrid Automatic Repeat reQuest) feedback on a scheduled data block under this scheme needs to be further discussed.

The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

Before introducing the technical solution of the present disclosure, first, the HARQ mechanism of the present disclosure is explained, and in a wireless communication system, due to the time-varying characteristic of a wireless channel and the influence of multipath fading, transmission of a signal is affected, thereby causing a failure of data transmission. In order to solve the problem, a wireless communication system introduces a Hybrid Automatic Repeat reQuest (HARQ) mechanism, and feeds back whether data reception is correct or not through HARQ feedback information of a receiving end, namely an acknowledgement signal ACK or a non-acknowledgement signal NACK; and the sending end determines whether to resend the sent data packet or not according to the HARQ feedback information.

The present disclosure relates to HARQ feedback for multiple downlink TBs (Transmission block data blocks) scheduled by a base station in a 4G network MTC FDD system. In a time domain, the HARQ feedback mechanism of the MTC FDD system of the present disclosure is the same as that of a 4G LTE (Long Term evolution), and there is a timing relationship between a time of performing HARQ feedback on a PDSCH (Physical Downlink Shared Channel) and a PDSCH Transmission end time, for example, performing HARQ feedback on Downlink data Transmission carried by a TB (Transmission block data block) by using a specified PUCCH (Physical Uplink Control Channel) resource in 4ms after the PDSCH is ended.

The execution body to which the present disclosure relates includes: the base station and the terminal in the MTC FDD system can be a base station provided with a large-scale antenna array, a sub-base station and the like. The terminal may be a User Equipment (UE), a User node, a mobile terminal, a tablet computer, or the like. In the specific implementation process, the base station and the terminal are independent and are simultaneously associated with each other, and the technical scheme provided by the disclosure is implemented together.

Based on this, the present disclosure provides a method for transmitting HARQ feedback information, which is applied in a terminal of an MTC FDD system.

Referring to fig. 1, a flowchart of a method for transmitting HARQ feedback information according to an exemplary embodiment is shown, where the method may include the following steps:

in step 11, HARQ PUCCH resource configuration information corresponding to a preset downlink scheduling mode is acquired; the preset downlink scheduling mode is that the base station schedules at least two Physical Downlink Shared Channel (PDSCH) resources for one downlink data transmission of the terminal by using one MTC Physical Downlink Control Channel (MPDCCH) information;

regarding the preset downlink scheduling mode, refer to fig. 2, which is a schematic view of an application scenario for transmitting HARQ feedback information according to an exemplary embodiment, taking a terminal as UE1 as an example, in the embodiment of the present disclosure, for a large data packet to be sent to UE1, a base station prepares to schedule 3 PDSCH resources, namely PDSCH 1, PDSCH 2, and PDSCH 3, for UE1 through an MPDCCH information, and is used to carry the downlink data transmission.

For the downlink scheduling mode, the terminal needs to determine corresponding HARQ PUCCH resource configuration information to determine how to perform HARQ feedback for partial downlink data transmission carried by each PDSCH resource.

In an embodiment, the HARQ PUCCH resource configuration information may be configuration information preset in the terminal and specified by a protocol.

In another embodiment of the present disclosure, the HARQ PUCCH resource configuration information may be sent by the base station to the terminal.

In this embodiment, the timing when the terminal acquires the HARQ PUCCH resource configuration information may include:

when the terminal accesses the cell network, the system information broadcasted by the base station is acquired, namely, the base station broadcasts the HARQ PUCCH resource configuration information to the terminal. Or, the base station sends the HARQ PUCCH resource configuration information to the terminal in a unicast mode.

In an embodiment, before the base station performs the preset downlink scheduling on the terminal, the base station may determine in advance whether the terminal has acquired the HARQ PUCCH resource configuration information; and if not, the base station sends the HARQ PUCCH resource configuration information to the terminal.

In another embodiment, the terminal may also actively request the base station to issue the HARQ PUCCH resource configuration information. The present disclosure does not limit the manner in which the terminal obtains the above HARQ PUCCH resource configuration information.

In step 12, determining target PUCCH index information corresponding to each PDSCH resource according to the HARQ PUCCH resource configuration information;

in the related art, the terminal may determine a HARQ PUCCH index of one PDSCH resource according to one MPDCCH information. The present disclosure is different from the related art: the terminal needs to determine HARQ PUCCH resource indexes respectively corresponding to multiple PDSCH resources according to one MPDCCH information, that is, target PUCCH index information. As shown in fig. 2, in the present disclosure, a terminal needs to determine 3 pieces of target PUCCH index information according to one MPDCCH information according to HARQ PUCCH resource configuration information.

Regarding the HARQ PUCCH resource index, assuming that the current PDSCH is downlink subframe No. 1, under the condition that the uplink and downlink time domains of the MTC FDD system are synchronous, the terminal needs to find out a PUCCH resource with a preset number, that is, a target PUCCH resource, from a PUCCH resource library of uplink subframe No. 5 at an interval of 4ms through the HARQ PUCCH resource index, where the target PUCCH resource is used to carry HARQ feedback information of PDSCH No. 1. By analogy, the correspondence between the three consecutive PDSCH resources scheduled by the MPDCCH and the uplink subframe carrying the HARQ feedback information thereof may be as shown in fig. 3. Namely, HARQ feedback information of PDSCH resources No. 1, 2, and 3 are respectively carried in PUCCH resources of uplink subframes No. 5, 6, and 7.

In this disclosure, according to the difference of the HARQ PUCCH resource configuration information, the implementation of step 12 may include at least the following three cases:

in a first case, the HARQ PUCCH resource configuration information includes: the first indication information is used for indicating the MTC terminal to determine one piece of PUCCH index information as reference according to an LTE FDD system protocol, and determining target PUCCH index information corresponding to each PDSCH resource.

Referring to fig. 4, which is a flowchart illustrating another method for transmitting HARQ feedback information according to an exemplary embodiment, step 12 may include:

in step 1211, determining PUCCH index information of a designated PDSCH resource according to a method of determining PUCCH index information in the LTE FDD system protocol;

in the embodiment of the present disclosure, the terminal determines target PUCCH index information corresponding to one PDSCH resource according to the first indication information.

Wherein, the PUCCH resource index corresponding to the one designated PDSCH resource may be derived from 3 parameters in the following formula:

n _ PUCCH ═ N _ PUCCH + N _ CCE + ARO formula (1)

Wherein, the N _ PUCCH is a starting position of a PUCCH resource carrying HARQ feedback information configured by a higher layer signaling. n _ CCE is the lowest CCE (Control Channel Element) index occupied by MPDCCH scheduling PDSCH; for example, assuming that MPDCCH occupies CCEs No. 4 to 7 in a Control Region (Control Region) of one subframe, the lowest CCE index is equal to 4. ARO (Assigned Resource Offset Resource allocation Offset) is a parameter carried by MPDCCH, characterizing HARQ PUCCH Resource Offset.

In an embodiment, the base station may instruct the terminal to calculate, in the first indication information, one PUCCH resource index information according to the starting PDSCH resource scheduled by the MPDCCH as a reference.

In step 1212, determining the PUCCH index information as first reference PUCCH index information;

it is assumed that the MPDCCH schedules three PDSCH resources, which are respectively denoted as: PDSCH 1, PDSCH 2, PDSCH 3. In the embodiment of the present disclosure, the target PUCCH index information corresponding to the PDSCH 1 calculated according to the above formula (1) may be determined as the first reference PUCCH index information.

In step 1213, target PUCCH index information corresponding to each PDSCH resource is determined according to the first reference PUCCH index information.

In this disclosure, after the reference PUCCH index information is determined, the target index information corresponding to each PDSCH resource may be determined according to the first reference PUCCH index information.

In the present disclosure, the implementation of step 1213 above may include at least two ways:

in a first mode, each piece of target PUCCH index information is the same as the first reference PUCCH index information.

If the first indication information includes: the first preset indication sub-information. The first preset indication sub-information is used for indicating the MTC terminal to serve as target PUCCH index information corresponding to each PDSCH resource according to PUCCH index information determined in an LTE FDD system.

The above step 1213 includes: and determining the first reference PUCCH index information as target PUCCH index information corresponding to each PDSCH resource according to the first preset indication sub-information.

For example, it is assumed that the first reference PUCCH index information is PUCCH resource index information corresponding to PDSCH 1 determined by the terminal according to formula (1) above. It is assumed that the first reference PUCCH index information is 8, that is, in the PUCCH resource pool of subframe No. 5, the PUCCH resource No. 8 is used to carry HARQ information of PDSCH 1. As shown in fig. 3, the PUCCH resource pool is carried in the control region Uc of the uplink subframe No. 5 and includes a plurality of PUCCH resources. And the target PUCCH resource index information is the number of the target PUCCH resource in the PUCCH resource library, and the target PUCCH resource is used for bearing HARQ feedback information.

The PUCCH resource pool of one subframe comprises the number of PUCCH resources, the number of the PUCCH resources contained in the PUCCH resource pool of different uplink subframes can be different according to the related knowledge, and the number of each PUCCH resource is determined according to the configuration information of the current subframe.

According to the first preset indication sub-information, the target PUCCH index information corresponding to PDSCH 2 and PDSCH 3 is also both 8.

The corresponding relationship between the PDSCH resource identifier, the uplink subframe carrying the HARQ information, and the target PUCCH index information may be as shown in table one below:

watch 1

In the embodiment of the present disclosure, according to the first preset indication sub-information, the terminal may calculate, according to MPDCCH information, a PUCCH resource index information of a designated PDSCH resource, such as a starting PDSCH resource, in a manner of calculating PUCCH resource index information of a PDSCH resource in an original LTE FDD system, and with this as a reference, determine target PUCCH index information of each PDSCH resource scheduled by MPDCCH as the reference PUCCH index information, thereby reducing terminal calculation amount and saving system signaling overhead.

Second, there is an offset between the target PUCCH index information corresponding to each PDSCH resource

In an embodiment of the present disclosure, the first indication information may include: second preset indication sub-information and first offset configuration information;

the second preset indication sub-information is used for indicating the MTC terminal to determine a first reference PUCCH index value corresponding to one designated PDSCH according to a mode of determining HARQ PUCCH resources in an LTE FDD system, and determining target PUCCH index information corresponding to each PDSCH resource according to the first reference PUCCH index value and the first preset offset.

Here, it is not limited that the terminal simultaneously acquires the second preset indication sub-information and the first offset configuration information. For example, the first offset configuration information may be pre-agreed by the system, or the base station may send the second preset indication sub-information to the terminal through PDCCH signaling or higher layer signaling, such as RRC signaling. In the present disclosure, both are logically classified as the above-described first indication information.

Accordingly, the specific implementation of step 1213 above includes:

In this disclosure, according to the difference of the offsets configured by the first offset configuration information, the implementation of the second method may include two cases:

in case one, the first offset configuration information includes: a predetermined offset value

Referring to fig. 5, which is a flowchart illustrating another method for transmitting HARQ feedback information according to an exemplary embodiment, step 1213 may include:

in step 1201, determining a target offset value corresponding to each PDSCH resource according to the timing sequence of each PDSCH resource and the preset offset value, where the target offset value is an integer multiple of the preset offset value;

the time sequence of each PDSCH resource is the sequence of each PDSCH resource scheduled by MPDCCH in the time domain, and as in the above example, PDSCH 1, PDSCH 2, and PDSCH 3 respectively represent the first PDSCH resource, the second PDSCH resource, and the third PDSCH resource scheduled by MPDCCH. That is, the sequence of the PDSCH resources is sequentially represented as: 1. 2 and 3.

In this embodiment of the present disclosure, assuming that the preset offset value is denoted as X, a target offset value corresponding to a PDSCH resource scheduled by MPDCCH and having a time sequence of n may be denoted as: (n-1) X.

For example, assuming that the preset offset value X is 2, the corresponding relationship between each PDSCH resource and the target offset value may be as shown in table two:

watch two

In step 1202, target PUCCH index information corresponding to each PDSCH resource is determined according to the first reference PUCCH index information and the target offset value.

As in the above example, it is still assumed that the first reference PUCCH index information is PUCCH resource index information corresponding to PDSCH 1 determined by the terminal according to the above formula (1). Assuming that the first reference PUCCH index information is 8, the target PUCCH index information corresponding to PDSCH 2 and PDSCH 3 is 10 and 12 in sequence according to the second preset indication sub-information.

In the embodiment of the present disclosure, the corresponding relationship between the PDSCH resource identifier, the uplink subframe carrying the HARQ information, and the target PUCCH index information may be as shown in table three below:

watch III

In case two, the first offset configuration information includes: preset offset corresponding to PDSCH resource time sequence

In the present disclosure, the system may be configured with different preset offsets for PDSCH resources of different scheduled timings. In an embodiment, the terminal may represent the acquired first offset configuration information as a first offset configuration list, where the first offset configuration list may include: the corresponding relationship between the PDSCH resource timing and the preset offset is exemplarily shown in table four:

watch four

Accordingly, the implementation of step 1213 above may refer to fig. 6, which is a flowchart illustrating another method for transmitting HARQ feedback information according to an exemplary embodiment, where step 1213 above may include:

in step 1203, querying the first offset configuration list according to a timing sequence of a current PDSCH resource, and determining a target offset corresponding to the timing sequence of the current PDSCH resource;

wherein, the timing of the current PDSCH resources refers to an order in which the current PDSCH resources are scheduled in the time domain as indicated in the MPDCCH information. For example, the timing of PDSCH 1 is 1. Accordingly, referring to the table four, the target offset corresponding to PDSCH 1 is X1.

In step 1204, the target PUCCH index information corresponding to the current PDSCH resource is determined according to the first reference PUCCH index information and the target offset.

Still assuming that the first reference PUCCH index information is 8, the target PUCCH index information corresponding to PDSCH 1, PDSCH 2, and PDSCH 3 is determined to be 8+ X1, 8+ X2, and 8+ X3, respectively, according to the second preset indication sub-information.

Then, in the embodiment of the present disclosure, the corresponding relationship between the PDSCH resource identifier, the uplink subframe carrying the HARQ information, and the target PUCCH index information may be as shown in the following table five:

watch five

In the embodiment of the disclosure, the system may sequentially designate the preset offset according to the time sequence for different PDSCH resources scheduled by one MPDCCH information, so as to realize flexible configuration of HARQ PUCCH resources in the preset downlink scheduling mode.

In the second case, the HARQ PUCCH resource configuration information obtained by the terminal includes: presetting a HARQ PUCCH resource set and second indication information; the preset HARQ PUCCH resource set comprises preset number of PUCCH resource index values to be selected; the second indication information is used for indicating the terminal to determine target PUCCH index information corresponding to each PDSCH resource from the preset HARQ PUCCH resource set according to a resource allocation offset (ARO) domain in the MPDCCH information.

Correspondingly, the step 12 specifically includes: and determining target PUCCH index information corresponding to each PDSCH resource from the preset HARQ PUCCH resource set according to the second indication information and the resource allocation offset ARO domain in the MPDCCH information.

According to the difference of the number of ARO domains contained in the MPDCCH information, the implementation of step 12 above may include at least the following two implementations:

in a first embodiment, if the MPDCCH message includes one ARO field;

referring to fig. 7, which is a flowchart illustrating another method for transmitting HARQ feedback information according to an exemplary embodiment, step 12 may include:

in step 1221, selecting second reference PUCCH index information from the preset HARQ PUCCH resource set according to the ARO domain;

in the embodiment of the disclosure, the terminal may select, according to the second indication information, one PUCCH index value from the preset HARQ PUCCH resource set by using one ARO domain of the MPDCCH information, as the reference PUCCH index information, which may be referred to as second reference PUCCH index information in the disclosure.

For example, it is assumed that the preset HARQ PUCCH resource set is: { R1, R2, R3, R4}, where each selectable PUCCH resource index value in the set is determined by the base station or system. The terminal may select an index value, such as R2, from the preset HARQ PUCCH resource set as the second reference PUCCH index information according to the indication of the ARO domain value in the MPDCCH information.

In step 1222, target PUCCH index information corresponding to each PDSCH resource is determined according to the second reference PUCCH index information.

Similar to the first case of step 12 above, after determining the second reference PUCCH index information, the terminal may determine target index information corresponding to each PDSCH resource in the following two ways.

In a first aspect, the second indication information includes: and the third preset indication sub-information. The third preset indication sub-information is used for indicating the MTC terminal to determine the same target PUCCH index information for each PDSCH resource from the preset HARQ PUCCH resource set according to an ARO domain in the MPDCCH information.

Then step 1222 includes: and determining the second reference PUCCH index information as target PUCCH index information corresponding to each PDSCH resource.

As in the above example, assuming that the second reference PUCCH index information is R2, the target PUCCH index information of PDSCH 1, PDSCH 2, PDSCH 3 is R2.

Similar to the above table, in the embodiment of the present disclosure, the corresponding relationship between the PDSCH resource identifier, the uplink subframe carrying the HARQ information, and the target PUCCH index information may be as shown in the following table six:

watch six

In a second aspect, the second indication information may include: the fourth preset indication sub-information and the second offset configuration information. The fourth preset indication sub-information is used for indicating the MTC terminal to determine, according to an ARO domain in the MPDCCH information, second reference PUCCH index information corresponding to a designated PDSCH resource from the preset HARQ PUCCH resource set, and determine, according to the second reference PUCCH index information and the second offset configuration information, target PUCCH index information corresponding to each PDSCH resource.

Then step 1222 may include:

Similarly, the implementation of step 1222 in the embodiment of the present disclosure may also include two cases according to the difference of the second offset configuration information.

In a first case, the second offset configuration information includes: a preset offset value.

Referring to fig. 8, which is a flowchart illustrating another method for transmitting HARQ feedback information according to an exemplary embodiment, step 1222 may include:

in step 1205, determining a target offset value corresponding to each PDSCH resource according to the timing sequence of each PDSCH resource and the preset offset value, where the target offset value is an integer multiple of the preset offset value;

in step 1206, determining target PUCCH index information corresponding to each PDSCH resource according to the second reference PUCCH index information and the target offset value.

The embodiment of the present disclosure is similar to the embodiment shown in fig. 5, and the difference is only that the determination manner of the reference PUCCH index information is different, so that a specific implementation process may refer to the embodiment shown in fig. 5, and is not described herein again.

In case two, the terminal may represent the determined second offset configuration information as a second offset configuration list, which includes: and the corresponding relation between the PDSCH resource time sequence and the preset offset.

Referring to fig. 9, which is a flowchart illustrating another method for transmitting HARQ feedback information according to an exemplary embodiment, step 1222 may include:

in step 1207, the second offset configuration list is queried according to the timing sequence of the current PDSCH resource, and a target offset corresponding to the timing sequence of the current PDSCH resource is determined;

in step 1208, determining target PUCCH index information corresponding to the current PDSCH resource according to the second reference PUCCH index information and the target offset.

As above, the embodiment of the present disclosure is similar to the embodiment shown in fig. 6, and the difference is only that the determination manner of the reference PUCCH index information is different, so that the specific implementation process may refer to the embodiment shown in fig. 6, and is not described herein again.

In a second embodiment, if the MPDCCH information includes: an ARO domain of a number equal to the PDSCH resources; the second indication information includes: and fifth preset indication sub-information.

Correspondingly, referring to fig. 10, which is a flowchart illustrating another method for transmitting HARQ feedback information according to an exemplary embodiment, step 12 may include:

in step 1223, according to the fifth preset indication sub-information, determining a target ARO domain corresponding to the current PDSCH resource;

in the embodiment of the present disclosure, the MPDCCH information includes ARO fields with the same number as that of scheduled PDSCH resources.

The terminal may determine a target ARO domain corresponding to each PDSCH resource according to the time sequence of the PDSCH resource. For example, assume that the base station informs the terminal in advance: the correspondence between the ARO domain and the PDSCH resource timing in the MPDCCH information is shown in table seven:

watch seven

Assuming that the current PDSCH resource is PDSCH 1, the timing sequence is 1, and it can be known from the lookup table seven that the first ARO field in the MPDCCH information is the target ARO field corresponding to PDSCH 1. The target ARO field is used for instructing the terminal how to determine target PUCCH index information corresponding to PDSCH 1 from a preset HARQ PUCCH resource set.

In step 1224, target PUCCH index information corresponding to the current PDSCH resource is determined from the preset HARQ PUCCH resource set according to the target ARO domain.

After the terminal determines a target ARO domain for a PDSCH resource, an index value may be selected from the preset HARQ PUCCH resource set according to an indication of the target ARO domain, and target PUCCH index information of the current PDSCH resource is determined.

The terminal may determine corresponding target PUCCH index information from a preset HARQ PUCCH resource set for each PDSCH resource scheduled by one MPDCCH information according to the above method.

For example, it is assumed that the target PUCCH index information determined by the terminal for each PDSCH resource according to the above method is: r1, R2 and R3. In the embodiment of the present disclosure, the corresponding relationship between the PDSCH resource, the ARO domain, the uplink subframe where the target PUCCH resource is located, and the target PUCCH index information may be as shown in table eight:

table eight

In the embodiment of the disclosure, the terminal may quickly determine a target PUCCH index information from a preset HARQ PUCCH resource set for different PDSCH resources scheduled by the terminal according to multiple ARO domains set in the MPDCCH information, which may reduce the amount of calculation of the terminal and improve the determination efficiency of the target PUCCH index information.

In a third case, the HARQ PUCCH configuration information acquired by the terminal may include: and third indication information. The third indication information is used for indicating the MTC terminal to determine target PUCCH index information corresponding to each PDSCH resource according to PRB index information of each PDSCH resource.

Correspondingly, the step 12 may specifically include: and according to the third indication information, determining target PUCCH index information corresponding to each PDSCH resource according to the physical resource block PRB index information of each PDSCH resource.

The content of the third indication information is different according to the quality of the channel where the PDSCH resource is located, and accordingly, the step 12 may include the following two embodiments.

In one embodiment, the third indication information includes: and sixth preset indication sub-information, configured to indicate the MTC terminal to determine target PUCCH index information for the current PDSCH resource according to preset PRB index information of the current PDSCH resource.

Referring to fig. 11, which is a flowchart illustrating another method for transmitting HARQ feedback information according to an exemplary embodiment, step 12 may include:

in step 1231, determining a physical resource block PRB index range of the current PDSCH resource;

in the embodiment of the present disclosure, the terminal may determine, according to a scheduling instruction in the related art, for example, in the MPDCCH, index information of a PRB occupied by one PDSCH resource in the system bandwidth or the MTC narrowband channel.

In step 1232, according to the sixth preset indication sub-information, determining a sum of a preset PRB index value of the current PDSCH resource and start position information of a preset HRAQ PUCCH resource as target PUCCH index information of the current PDSCH resource.

In an embodiment of the present disclosure, the sixth preset indication sub-information may include: the method comprises the steps of presetting PRB index information, presetting information such as the starting position of HRAQ PUCCH resources and the like.

The terminal may calculate the target PUCCH index information corresponding to one PDSCH resource according to the following formula:

n _ PUCCH ═ N _ PRB + N _ PUCCH formula (2)

Wherein, n _ PUCCH represents index information of a target PUCCH resource of a PDSCH resource in a PUCCH resource base of a target uplink subframe;

n _ PRB is PRB index information related to current PDSCH resources, that is, the preset PRB index information, which may be the lowest PRB index information, the highest PRB index information, or one designated PRB index information of the PDSCH.

The N _ PUCCH is the starting position of the HARQ PUCCH resource, and the parameter may be sent to the terminal by the base station through a higher layer signaling.

For example, suppose that the index range of PRBs occupied by PDSCH 1 in the preset system bandwidth is: 2-6, assuming that the system bandwidth is 20 mhz and includes bandwidth resources of 100 PRBs, the PDSCH 1 scheduled by the MPDCCH occupies the 2 nd to 6 th PRBs within the preset system bandwidth. If the n _ PRB is configured as the lowest PRB index information of the PDSCH, in the above example, n _ PRB is 2.

Assuming that N _ PUCCH is 8, the target PUCCH index information corresponding to the PDSCH resource, that is, N _ PUCCH being 8+2 being 10, may be calculated according to the above equation (2).

By analogy, the terminal can determine target PUCCH index information corresponding to each PDSCH resource scheduled by an MPDCCH according to index information of a PRB (Physical resource block) occupied by the PDSCH resource.

In a second embodiment, the third indication information may include: the seventh preset indication sub-information is used for indicating the MTC terminal to determine third reference PUCCH index information corresponding to the current PDSCH resource according to preset PRB index information of the current PDSCH resource; and determining target PUCCH index information corresponding to the current PDSCH resource according to the third reference PUCCH index information and the third preset offset.

Referring to fig. 12, which is a flowchart illustrating another method for transmitting HARQ feedback information according to an exemplary embodiment, step 12 may include:

in step 1233, determining a physical resource block PRB index range of the current PDSCH resource;

in step 1234, according to the seventh preset indication sub-information, determining a sum of a preset PRB index value of the current PDSCH resource and start position information of a preset HRAQ PUCCH resource as third reference PUCCH index information corresponding to the current PDSCH resource;

in step 1235, the target PUCCH index information of the current PDSCH resource is determined according to the third reference PUCCH index information and the third preset offset.

In the embodiment of the present disclosure,

steps

1233 and 1234 are similar to

steps

1231 and 1232, except that the PUCCH resource index information determined in step 1234 is used as the reference PUCCH index information, i.e., the third reference PUCCH index information. And further determining target PUCCH index information corresponding to one PDSCH resource according to the third reference PUCCH index information and a third preset offset preset by a system or a base station.

In the embodiment of the present disclosure, the determination process of the target PUCCH index information may be shown in the following formula (3):

n _ PUCCH is N _ PRB + N _ PUCCH + offset formula (3)

The offset represents the third preset offset, and may be issued to the terminal by the base station through a high-level signaling, such as an RRC signaling or a PDCCH.

The embodiment of the disclosure is applicable to a situation that the target PUCCH resource determined according to the formula (2) is not suitable for transmitting HRAQ feedback information, for example, if there are many resource fragments in the PUCCH resource, the base station instructs the terminal to determine the offset PUCCH resource as the target PUCCH resource according to a preset offset.

As described above, the base station may determine, according to any one of the above situations, corresponding target PUCCH index information for each PDSCH resource scheduled by the MPDCCH according to the obtained HARQ PUCCH configuration information.

In step 13, the HARQ feedback information of the downlink data transmission carried by each PDSCH resource is loaded in the target PUCCH resource corresponding to the target PUCCH index information and sent to the base station.

After the system completes the downlink data transmission carried by one PDSCH resource, the terminal generates corresponding HARQ feedback information, namely an ACK signal or a HACK signal according to whether the received data is correct or not, and the HARQ feedback information is recorded in the target PUCCH resource indicated by the target PUCCH index information and is sent to the base station, so that the base station determines whether to retransmit the downlink data carried by the PDSCH or not according to the received HARQ feedback information.

In summary, in the present disclosure, a terminal in an MTC FDD system may determine, according to HARQ PUCCH configuration information and one MPDCCH information, target PUCCH index information of multiple PDSCH resources scheduled by the MPDCCH, and may effectively improve the determination efficiency of the target PUCCH index information. Correspondingly, the base station in the MTC FDD system can realize scheduling of a plurality of PDSCH resources through one MPDCCH, avoid sending one PDCCH message for each PDSCH resource, and effectively save signaling overhead.

Correspondingly, the disclosure also provides a method for transmitting hybrid automatic repeat request HARQ feedback information, which is applied to a base station of an MTC FDD system.

In step 22, the HARQ PUCCH resource configuration information is sent to the MTC terminal, so that the MTC terminal determines a target physical uplink control channel PUCCH resource according to the HARQ PUCCH resource configuration information in the preset downlink scheduling mode, loads HARQ feedback information for downlink data transmission in the target PUCCH resource, and feeds back the HARQ feedback information to the base station.

In the present disclosure, the base station may send the HARQ PUCCH resource configuration information to the terminal through a broadcast signaling, a high layer signaling, and a physical layer signaling. The higher layer signaling may be RRC (Radio Resource Control) signaling, MAC (Medium Access Control) CE (Control Element) signaling, and the like.
