Description

[0001] Divisional application statement

[0002] This application is a divisional application based on the Chinese invention patent application with application number 201880001486.7, application date July 25, 2018, and invention name “Method, terminal and base station for transmitting HARQ feedback information”. Technical Field

[0003] The present disclosure relates to the field of communication technology, and in particular to a method, a terminal and a base station for transmitting HARQ feedback information. Background Art

[0004] With the development of the Internet of Things, MTC (Machine Type Communication), a communication technology between machines without human intervention, is a typical representative of cellular Internet of Things technology. It is widely used in smart cities, such as meter reading; smart agriculture, such as the collection of information such as temperature and humidity; smart transportation, such as shared bicycles, and many other fields.

[0005] In the related art, the MTC FDD (Frequency Division Dual) system schedules wireless resources as follows: one MPDCCH (MTC Physical Downlink Control Channel) schedules one PDSCH (Physical Downlink Shared Channel) or PUSCH (Physical Uplink Shared Channel). MTC terminals need to receive and blindly detect MPDCCH before receiving or sending data. In the case where a large data packet needs to be sent to the MTC terminal, several rounds of scheduling are required to complete it. In most cases, due to similar channel conditions, the scheduling contents of several MPDCCHs are similar. Even in this case, the terminal still needs to demodulate each scheduled MPDCCH, resulting in excessive power consumption.

[0006] In order to avoid the power consumption in the above situation, the related art proposes a scheme for MPDCCH to schedule multiple uplink or downlink TBs (Transmission blocks). In this scheme, how to perform HARQ (Hybrid Automatic Repeat reQuest) feedback on the scheduled data blocks needs further discussion. Summary of the invention

[0172] The HARQ feedback information of the downlink data transmission carried by each PDSCH resource is loaded into the target PUCCH resource corresponding to the target PUCCH index information, and sent to the base station.

[0173] According to an eighth aspect of an embodiment of the present disclosure, a user equipment is provided, including:

[0174] processor;

[0175] a memory for storing processor-executable instructions;

[0176] Wherein, the processor is configured to:

[0177] Determine HARQ PUCCH resource configuration information corresponding to a preset downlink scheduling mode; wherein the preset downlink scheduling mode is to use an MTC physical downlink control channel MPDCCH information to schedule at least two physical downlink shared channel PDSCH resources for one downlink data transmission of the MTC terminal;

[0178] The HARQ PUCCH resource configuration information is sent to the MTC terminal, so that the MTC terminal determines the target physical uplink control channel PUCCH resource according to the HARQ PUCCH resource configuration information in the preset downlink scheduling mode and loads the HARQ feedback information of the downlink data transmission into the target PUCCH resource and feeds it back to the base station.

[0179] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0180] The disclosed embodiment provides a method for transmitting HARQ feedback information. When a base station uses one MPDCCH to schedule multiple PDSCH resources to carry one downlink data transmission for an MTC terminal, the terminal can determine corresponding target PUCCH index information for the multiple PDSCHs scheduled by the above MPDCCH information according to the acquired HARQ PUCCH resource configuration information. In the above preset downlink scheduling mode for the MTC FDD system, a new method for determining the target PUCCH resource is implemented. The target PUCCH index information of multiple PDSCH resources can be accurately determined according to one MPDCCH information, thereby saving system signaling overhead.

[0209] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0210] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. The singular forms of "a", "said" and "the" used in this disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0211] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0212] Before introducing the technical solution of the present invention, the HARQ mechanism of the present invention is first explained. In a wireless communication system, the time-varying characteristics of the wireless channel and the influence of multipath fading will affect the transmission of the signal, thereby causing the failure of data transmission. In order to solve this problem, the wireless communication system introduces the HARQ (Hybrid Automatic Repeat reQuest) mechanism, which uses the HARQ feedback information of the receiving end, i.e., the confirmation signal ACK or the non-confirmation signal NACK, to feedback whether the data is received correctly; the sending end decides whether it needs to resend the data packet that has been sent based on the above HARQ feedback information.

[0213] The present disclosure relates to HARQ feedback of multiple downlink TBs (Transmission block data blocks) scheduled by a base station in a 4G network MTC FDD system. In the time domain, the HARQ feedback mechanism of the MTC FDD system of the present disclosure is the same as that of the 4G LTE (Long Term Evolution) system. There is a timing relationship between the time when the PDSCH (Physical Downlink Shared Channel) is performed on the HARQ feedback and the time when the PDSCH transmission ends. For example, 4ms after the end of the PDSCH, the HARQ feedback is performed on the downlink data transmission carried by the TB (Transmission block data block) using the designated PUCCH (Physical Uplink Control Channel) resources.

[0214] The execution subjects involved in the present disclosure include: base stations and terminals in the MTC FDD system, wherein the base station may be a base station or a sub-base station equipped with a large-scale antenna array. The terminal may be a user equipment (UE), a user node, a mobile terminal or a tablet computer, etc. In the specific implementation process, the base station and the terminal are independent of each other, but are interconnected to jointly implement the technical solution provided by the present disclosure.

[0215] Based on this, the present disclosure provides a method for transmitting hybrid automatic repeat request HARQ feedback information, which is applied to a terminal of an MTC FDD system.

[0216] See also Figure 1 According to a flow chart of a method for transmitting HARQ feedback information according to an exemplary embodiment, the method may include the following steps:

[0217] In step 11, HARQ PUCCH resource configuration information corresponding to a preset downlink scheduling mode is obtained; wherein the preset downlink scheduling mode is that the base station uses one MTC physical downlink control channel MPDCCH information to schedule at least two physical downlink shared channel PDSCH resources for one downlink data transmission of the terminal;

[0218] For the above preset downlink scheduling mode, please refer to Figure 2 According to a schematic diagram of an application scenario for transmitting HARQ feedback information according to an exemplary embodiment, taking the terminal as UE1 as an example, in the embodiment of the present disclosure, for a large data packet to be sent to UE1, the base station is ready to schedule three PDSCH resources for UE1 through one MPDCCH information, namely, PDSCH 1, PDSCH 2, and PDSCH 3, for carrying the above-mentioned downlink data transmission.

[0219] For the above downlink scheduling mode, the terminal needs to determine the corresponding HARQ PUCCH resource configuration information to determine how to perform HARQ feedback for the partial downlink data transmission carried by each PDSCH resource.

[0220] In one embodiment, the HARQ PUCCH resource configuration information may be configuration information specified by a protocol and preset in the terminal.

[0221] In another embodiment of the present disclosure, the above HARQ PUCCH resource configuration information may be sent by the base station to the terminal.

[0222] In this embodiment, the timing for the terminal to obtain the above HARQ PUCCH resource configuration information may include:

[0223] When the terminal accesses the cell network, it obtains the system information broadcast by the base station, that is, the base station broadcasts the HARQ PUCCH resource configuration information to the terminal. Alternatively, the base station sends the above HARQ PUCCH resource configuration information to the terminal in a unicast manner.

[0224] In one embodiment, before performing the above-mentioned preset downlink scheduling on the terminal, the base station may determine in advance whether the terminal has acquired the above-mentioned HARQ PUCCH resource configuration information; if not, the base station sends the HARQ PUCCH resource configuration information to the terminal.

[0225] In another embodiment, the terminal may also actively request the base station to send 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.

[0226] In step 12, target PUCCH index information corresponding to each of the PDSCH resources is determined according to the HARQ PUCCH resource configuration information;

[0227] In the related art, a terminal can determine the HARQ PUCCH index of a PDSCH resource based on one MPDCCH information. The present disclosure is different from the related art in that the terminal needs to determine the HARQ PUCCH resource indexes corresponding to multiple PDSCH resources, that is, the target PUCCH index information, based on one MPDCCH information. Figure 2 As shown, in the present disclosure, the terminal needs to determine three target PUCCH index information according to one MPDCCH information based on the HARQ PUCCH resource configuration information.

[0228] Regarding the HARQ PUCCH resource index, assuming that the current PDSCH is the No. 1 downlink subframe, in the case of uplink and downlink time domain synchronization in the MTC FDD system, the terminal needs to find the preset number of PUCCH resources, i.e., the target PUCCH resources, from the PUCCH resource pool of the No. 5 uplink subframe with an interval of 4ms through the above HARQ PUCCH resource index. The target PUCCH resources are used to carry the HARQ feedback information of the No. 1 PDSCH. By analogy, the correspondence between the three consecutive PDSCH resources scheduled by the MPDCCH and the uplink subframes carrying their HARQ feedback information can be as follows: Figure 3 That is, the HARQ feedback information of the 1st, 2nd and 3rd PDSCH resources are respectively carried in the PUCCH resources of the 5th, 6th and 7th uplink subframes.

[0229] In the present disclosure, according to the difference of the above HARQ PUCCH resource configuration information, the implementation of the above step 12 may include at least the following three situations:

[0230] In the first case, the HARQ PUCCH resource configuration information includes: first indication information, where the first indication information is used to instruct the MTC terminal to determine a PUCCH index information as a reference according to the LTE FDD system protocol to determine the target PUCCH index information corresponding to each of the PDSCH resources.

[0231] See also Figure 4 According to a flowchart of another method for transmitting HARQ feedback information shown in an exemplary embodiment, the above step 12 may include:

[0232] In step 1211, according to the method for determining PUCCH index information in the LTE FDD system protocol, PUCCH index information of a specified PDSCH resource is determined;

[0233] In the disclosed embodiment, the terminal determines the target PUCCH index information corresponding to a PDSCH resource according to the first indication information.

[0234] The PUCCH resource index corresponding to the above-mentioned specified PDSCH resource can be derived from the three parameters in the following formula:

[0235] n_PUCCH=N_PUCCH+n_CCE+ARO formula (1)

[0236] Wherein, N_PUCCH is the starting position of the PUCCH resource carrying HARQ feedback information configured by high-layer signaling. n_CCE is the lowest CCE (Control Channel Element) index occupied by the MPDCCH that schedules the PDSCH; for example, assuming that the MPDCCH occupies CCE No. 4 to 7 in the control region (Control Region) of a subframe, the lowest CCE index is equal to 4. ARO (Assigned Resource Offset) is a parameter carried by the MPDCCH, which represents the HARQ PUCCH resource offset.

[0237] In one embodiment, the base station may instruct the terminal in the first indication information to calculate a PUCCH resource index information as a reference according to the starting PDSCH resource scheduled by the MPDCCH.

[0238] In step 1212, the PUCCH index information is determined as first reference PUCCH index information;

[0239] Assume that MPDCCH schedules three PDSCH resources, which are respectively represented as: PDSCH 1, PDSCH 2, and PDSCH 3. In the embodiment of the present disclosure, the target PUCCH index information corresponding to PDSCH 1 calculated according to the above formula (1) can be determined as the first reference PUCCH index information.

[0240] In step 1213, target PUCCH index information corresponding to each of the PDSCH resources is determined according to the first reference PUCCH index information.

[0241] In the present disclosure, after the reference PUCCH index information is determined, the target index information corresponding to each PDSCH resource can be determined according to the first reference PUCCH index information.

[0242] In the present disclosure, the implementation of the above step 1213 may include at least two methods:

[0243] Method 1: each target PUCCH index information is the same as the first reference PUCCH index information.

[0244] If the first indication information includes: first preset indication sub-information. The first preset indication sub-information is used to instruct the MTC terminal to use a PUCCH index information determined in the LTE FDD system as the target PUCCH index information corresponding to each of the PDSCH resources.

[0245] Then the above step 1213 includes: according to the first preset indication sub-information, determining the first reference PUCCH index information as the target PUCCH index information corresponding to each of the PDSCH resources.

[0246] Exemplarily, it is assumed that the first reference PUCCH index information is the PUCCH resource index information corresponding to PDSCH 1 determined by the terminal according to the above formula (1). It is assumed that the above first reference PUCCH index information is 8, that is, in the PUCCH resource pool of the 5th subframe, the 8th PUCCH resource is used to carry the HARQ information of the above PDSCH 1. Figure 3 As shown, the PUCCH resource pool is carried in the control region Uc of the fifth uplink subframe and includes multiple PUCCH resources. The target PUCCH resource index information is the serial number of the target PUCCH resource in the PUCCH resource pool, and the target PUCCH resource is used to carry HARQ feedback information.

[0247] The number of PUCCH resources included in the PUCCH resource pool of a subframe is determined according to relevant knowledge. The number of PUCCH resources included in the PUCCH resource pool of different uplink subframes may be different. The number of each PUCCH resource is determined according to the configuration information of the current subframe.

[0248] According to the first preset indication sub-information, the target PUCCH index information corresponding to PDSCH 2 and PDSCH 3 is also 8 respectively.

[0249] 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 1:

[0250]

[0251] Table 1

[0252] In the embodiment of the present disclosure, the terminal may calculate the PUCCH resource index information of a designated PDSCH resource such as the starting PDSCH resource according to the MPDCCH information in accordance with the method of calculating the PUCCH resource index information of a PDSCH resource in the original LTE FDD system according to the first preset indication sub-information. With reference to this, the target PUCCH index information of each PDSCH resource scheduled by the MPDCCH is determined as the reference PUCCH index information, thereby reducing the calculation amount of the terminal and saving the system signaling overhead.

[0253] Method 2: There is an offset between the target PUCCH index information corresponding to each PDSCH resource

[0254] In an embodiment of the present disclosure, the first indication information may include: second preset indication sub-information and first offset configuration information;

[0255] Among them, the second preset indication sub-information is used to instruct the MTC terminal to determine a first reference PUCCH index value corresponding to a specified PDSCH in accordance with the method of determining HARQ PUCCH resources in the LTE FDD system, and determine the target PUCCH index information corresponding to each of the PDSCH resources based on the first reference PUCCH index value and the first preset offset.

[0256] It should be noted here that, for the terminal, it is not limited to simultaneously obtain 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 high-layer signaling such as RRC signaling before sending the second preset indication sub-information. In the present disclosure, the two are logically classified as the first indication information.

[0257] Accordingly, the specific implementation of the above step 1213 includes:

[0258] According to the second preset indication sub-information, according to the first reference PUCCH index information and the first offset configuration information, the target PUCCH index information corresponding to each of the PDSCH resources is determined.

[0259] In the present disclosure, according to the difference of the offset configured by the first offset configuration information, the implementation of the above-mentioned method 2 may include two cases:

[0260] Case 1: The first offset configuration information includes: a preset offset value

[0261] See also Figure 5 According to a flowchart of another method for transmitting HARQ feedback information shown in an exemplary embodiment, the above step 1213 may include:

[0262] In step 1201, a target offset value corresponding to each PDSCH resource is determined according to the timing of each PDSCH resource and the preset offset value, where the target offset value is an integer multiple of the preset offset value;

[0263] The timing of each PDSCH resource is the order of each PDSCH resource scheduled by the MPDCCH in the time domain. For 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 the MPDCCH. That is, the timing of each PDSCH resource is represented as 1, 2, and 3.

[0264] In the embodiment of the present disclosure, assuming that the preset offset value is represented by X, the target offset value corresponding to the PDSCH resource scheduled by the MPDCCH and with a timing of n can be represented by: (n-1)X.

[0265] Exemplarily, assuming that the preset offset value X=2, the corresponding relationship between the above-mentioned PDSCH resources and the target offset value may be as shown in Table 2:

[0266]

[0267] Table 2

[0268] In step 1202, target PUCCH index information corresponding to each of the PDSCH resources is determined according to the first reference PUCCH index information and the target offset value.

[0269] As in the above example, it is still assumed that the first reference PUCCH index information is the PUCCH resource index information corresponding to PDSCH1 determined by the terminal according to the above formula (1). Assuming that the above first reference PUCCH index information is 8, then according to the above second preset indication sub-information, the target PUCCH index information corresponding to PDSCH 2 and PDSCH 3 are 10 and 12 respectively.

[0270] In the embodiment of the present disclosure, the correspondence between the PDSCH resource identifier, the uplink subframe carrying HARQ information, and the target PUCCH index information may be as shown in the following Table 3:

[0271]

[0272] Table 3

[0273] Case 2: The first offset configuration information includes: the preset offset corresponding to the PDSCH resource timing

[0274] In the present disclosure, the system may configure different preset offsets for PDSCH resources of different scheduled timings. In one embodiment, the terminal may represent the acquired first offset configuration information as a first offset configuration list, and the first offset configuration list may include: the correspondence between the PDSCH resource timing and the preset offset, as shown in Table 4 for example:

[0275]

[0276] Table 4

[0277] Accordingly, the implementation of the above step 1213 can be found in Figure 6According to a flowchart of another method for transmitting HARQ feedback information shown in an exemplary embodiment, the above step 1213 may include:

[0278] In step 1203, the first offset configuration list is queried according to the timing of the current PDSCH resource to determine the target offset corresponding to the timing of the current PDSCH resource;

[0279] The timing of the current PDSCH resource refers to the order in which the current PDSCH resource is scheduled in the time domain as indicated in the MPDCCH information. For example, the timing of PDSCH 1 is 1. Accordingly, it can be seen from Table 4 above that the target offset corresponding to PDSCH 1 is X1.

[0280] 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.

[0281] Still assuming that the first reference PUCCH index information is 8, then according to the second preset indication sub-information, the target PUCCH index information corresponding to PDSCH 1, PDSCH 2, and PDSCH 3 are determined to be 8+X1, 8+X2, and 8+X3 respectively.

[0282] In the embodiment of the present disclosure, the correspondence 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 5:

[0283]

[0284] Table 5

[0285] In the disclosed embodiment, the system may specify preset offsets in sequence for different PDSCH resources scheduled by one MPDCCH information, thereby realizing flexible configuration of HARQ PUCCH resources in the above preset downlink scheduling mode.

[0286] In the second case, the HARQ PUCCH resource configuration information acquired by the terminal includes: a preset HARQ PUCCH resource set and second indication information; wherein the preset HARQ PUCCH resource set includes a preset number of to-be-selected PUCCH resource index values; and the second indication information is used to instruct the terminal to determine the target PUCCH index information corresponding to each of the PDSCH resources from the preset HARQ PUCCH resource set according to the resource allocation offset ARO field in the MPDCCH information.

[0287] Correspondingly, the above step 12 specifically includes: determining, according to the second indication information, and according to the resource allocation offset ARO field in the MPDCCH information, the target PUCCH index information corresponding to each of the PDSCH resources from the preset HARQ PUCCH resource set.

[0288] Depending on the number of ARO fields included in the MPDCCH information, the implementation of step 12 may include at least the following two implementations:

[0289] Embodiment 1: If the MPDCCH information includes an ARO field;

[0290] See also Figure 7 According to a flowchart of another method for transmitting HARQ feedback information shown in an exemplary embodiment, the above step 12 may include:

[0291] In step 1221, second reference PUCCH index information is selected from the preset HARQ PUCCH resource set according to the ARO region;

[0292] In the embodiment of the present disclosure, the terminal may select a PUCCH index value from a preset HARQ PUCCH resource set according to the second indication information and using an ARO field of the MPDCCH information as reference PUCCH index information, which may be referred to as second reference PUCCH index information in the present disclosure.

[0293] Exemplarily, assuming that the preset HARQ PUCCH resource set is: {R1, R2, R3, R4}, wherein each optional PUCCH resource index value in the set is determined by the base station or the 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 field value in the MPDCCH information.

[0294] In step 1222, target PUCCH index information corresponding to each of the PDSCH resources is determined according to the second reference PUCCH index information.

[0295] Similar to the first case of step 12 above, after determining the second reference PUCCH index information, the terminal may determine the target index information corresponding to each PDSCH resource in the following two ways.

[0296] In a first embodiment, the second indication information includes: third preset indication sub-information. The third preset indication sub-information is used to instruct the MTC terminal to determine the same target PUCCH index information for each of the PDSCH resources from the preset HARQ PUCCH resource set according to the ARO field in the MPDCCH information.

[0297] Then the above step 1222 includes: determining the second reference PUCCH index information as the target PUCCH index information corresponding to each of the PDSCH resources.

[0298] 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, and PDSCH 3 are all R2.

[0299] Similar to the above Table 1, in the embodiment of the present disclosure, the correspondence between the PDSCH resource identifier, the uplink subframe carrying HARQ information, and the target PUCCH index information may be as shown in the following Table 6:

[0300]

[0301] Table 6

[0302] In a second embodiment, the second indication information may include: fourth preset indication sub-information and second offset configuration information. The fourth preset indication sub-information is used to instruct the MTC terminal to determine the second reference PUCCH index information corresponding to the specified PDSCH resource from the preset HARQ PUCCH resource set according to the ARO field in the MPDCCH information, and determine the target PUCCH index information corresponding to each of the PDSCH resources according to the second reference PUCCH index information and the second offset configuration information.

[0303] Then the above step 1222 may include:

[0304] According to the second reference PUCCH index information and the second offset configuration information, target PUCCH index information corresponding to each of the PDSCH resources is determined.

[0305] Similarly, according to different second offset configuration information, the implementation of the above step 1222 in the embodiment of the present disclosure may also include two situations.

[0306] Case 1: the second offset configuration information includes: a preset offset value.

[0307] See also Figure 8 According to a flowchart of another method for transmitting HARQ feedback information shown in an exemplary embodiment, the above step 1222 may include:

[0308] In step 1205, a target offset value corresponding to each PDSCH resource is determined according to the timing of each PDSCH resource and the preset offset value, where the target offset value is an integer multiple of the preset offset value;

[0309] In step 1206, the target PUCCH index information corresponding to each of the PDSCH resources is determined according to the second reference PUCCH index information and the target offset value.

[0310] The present disclosure embodiment is different from the above Figure 5 The embodiments shown are similar, the only difference is that the reference PUCCH index information is determined in a different manner. Therefore, the specific implementation process can be referred to in Figure 5 The embodiments shown will not be described in detail here.

[0311] In case 2, the terminal may represent the determined second offset configuration information as a second offset configuration list, where the second offset configuration list includes: a correspondence between a PDSCH resource timing and a preset offset.

[0312] See also Fig. 9 According to a flowchart of another method for transmitting HARQ feedback information shown in an exemplary embodiment, the above step 1222 may include:

[0313] In step 1207, the second offset configuration list is queried according to the timing of the current PDSCH resource to determine the target offset corresponding to the timing of the current PDSCH resource;

[0314] In step 1208, target PUCCH index information corresponding to the current PDSCH resource is determined according to the second reference PUCCH index information and the target offset.

[0315] As above, the embodiments of the present disclosure are similar to the above Figure 6 The embodiments shown are similar, the only difference is that the reference PUCCH index information is determined in a different manner. Therefore, the specific implementation process can be referred to in Figure 6 The embodiments shown will not be described in detail here.

[0316] Embodiment 2: If the MPDCCH information includes: ARO regions having a number equal to the number of PDSCH resources; the second indication information includes: fifth preset indication sub-information.

[0317] The fifth preset indication sub-information is used to instruct the MTC terminal to determine the target PUCCH index information corresponding to each PDSCH resource from the preset HARQ PUCCH resource set according to each ARO field in the MPDCCH information.

[0318] Accordingly, see Fig.10 According to a flowchart of another method for transmitting HARQ feedback information shown in an exemplary embodiment, the above step 12 may include:

[0319] In step 1223, the target ARO region corresponding to the current PDSCH resource is determined according to the fifth preset indication sub-information;

[0320] In the disclosed embodiment, the MPDCCH information is provided with ARO fields of the same number as the scheduled PDSCH resources.

[0321] The terminal can determine the target ARO region corresponding to each PDSCH resource according to the timing of the PDSCH resource. For example, it is assumed that the base station informs the terminal in advance that the corresponding relationship between the ARO region and the timing of the PDSCH resource in the MPDCCH information is as shown in Table 7:

[0323] Table 7

[0324] Assuming that the current PDSCH resource is PDSCH 1, its timing is 1. By querying Table 7, it can be seen that the first ARO field in the MPDCCH information is the target ARO field corresponding to PDSCH 1. The target ARO field is used to instruct the terminal how to determine the target PUCCH index information corresponding to PDSCH 1 from the preset HARQ PUCCH resource set.

[0325] 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 region.

[0326] After the terminal determines a target ARO region for a PDSCH resource, it may select an index value from the preset HARQ PUCCH resource set according to the indication of the target ARO region to determine the target PUCCH index information of the current PDSCH resource.

[0327] The terminal may determine the corresponding target PUCCH index information from the preset HARQ PUCCH resource set for each PDSCH resource scheduled by an MPDCCH information according to the above method.

[0328] Exemplarily, assuming that the target PUCCH index information determined by the terminal for each PDSCH resource according to the above method is respectively: R1, R2, and R3. In the embodiment of the present disclosure, the corresponding relationship between the PDSCH resource, the ARO region, the uplink subframe where the target PUCCH resource is located, and the target PUCCH index information can be shown in Table 8:

[0329]

[0330]

[0331] Table 8

[0332] In the disclosed embodiment, the terminal can quickly determine a target PUCCH index information from a preset HARQ PUCCH resource set for different PDSCH resources scheduled for the terminal according to multiple ARO fields set in the MPDCCH information, thereby reducing the amount of calculation of the terminal and improving the efficiency of determining the target PUCCH index information.

[0333] In a third case, the HARQ PUCCH configuration information acquired by the terminal may include: third indication information. The third indication information is used to instruct the MTC terminal to determine the target PUCCH index information corresponding to each of the PDSCH resources according to the PRB index information of each of the PDSCH resources.

[0334] Correspondingly, the above step 12 may specifically include: determining the target PUCCH index information corresponding to each of the PDSCH resources according to the third indication information and the physical resource block PRB index information of each of the PDSCH resources.

[0335] Depending on the quality of the channel where the PDSCH resource is located, the content of the third indication information is also different. Accordingly, the step 12 may include the following two implementation modes.

[0336] In the first implementation mode, the third indication information includes: sixth preset indication sub-information, and the sixth preset indication sub-information is used to instruct the MTC terminal to determine the target PUCCH index information for the current PDSCH resource according to the preset PRB index information of the current PDSCH resource.

[0337] See also Fig.11 According to a flowchart of another method for transmitting HARQ feedback information shown in an exemplary embodiment, the above step 12 may include:

[0338] In step 1231, a physical resource block PRB index range of the current PDSCH resource is determined;

[0339] In the embodiment of the present disclosure, the terminal may determine the index information of the PRB occupied by a PDSCH resource in the system bandwidth or the MTC narrowband channel according to relevant technologies such as the scheduling instruction in the MPDCCH.

[0340] In step 1232, according to the sixth preset indication sub-information, the sum of the preset PRB index value of the current PDSCH resource and the starting position information of the preset HRAQ PUCCH resource is determined as the target PUCCH index information of the current PDSCH resource.

[0341] In the embodiment of the present disclosure, the sixth preset indication sub-information may include: preset PRB index information, a starting position of preset HRAQ PUCCH resources and other information.

[0342] The terminal can calculate the target PUCCH index information corresponding to a PDSCH resource according to the following formula:

[0343] n_PUCCH=n_PRB+N_PUCCH Formula (2)

[0344] Wherein, n_PUCCH represents the index information of the target PUCCH resource of a PDSCH resource in the PUCCH resource pool of the target uplink subframe;

[0345] n_PRB is the PRB index information related to the current PDSCH resource, that is, the preset PRB index information mentioned above, and the preset PRB index information can be the lowest PRB index information, the highest PRB index information or a specified PRB index information of the PDSCH.

[0346] N_PUCCH is the starting position of the HARQ PUCCH resource, and this parameter can be sent by the base station to the terminal through high-layer signaling.

[0347] Exemplarily, assuming that the index range of the PRBs occupied by PDSCH 1 in the preset system bandwidth is 2 to 6, assuming that the above system bandwidth is a bandwidth resource of 20 MHz and includes 100 PRBs, then the PDSCH 1 scheduled by the MPDCCH occupies the 2nd to 6th PRBs in the above preset system bandwidth. If the above n_PRB is configured as the lowest PRB index information of the PDSCH, then in the above example, n_PRB=2.

[0348] Assuming that N_PUCCH is 8, the target PUCCH index information corresponding to the PDSCH resource can be calculated according to the above formula (2), that is, n_PUCCH=8+2=10.

[0349] By analogy, the terminal can determine the target PUCCH index information corresponding to each PDSCH resource scheduled by an MPDCCH according to the index information of the PRB (Physical resource block) occupied by the PDSCH resource.

[0350] In the second implementation mode, the third indication information may include: seventh preset indication sub-information and third preset offset, wherein the seventh preset indication sub-information is used to instruct the MTC terminal to determine the third reference PUCCH index information corresponding to the current PDSCH resource according to the preset PRB index information of the current PDSCH resource; and determine the target PUCCH index information corresponding to the current PDSCH resource based on the third reference PUCCH index information and the third preset offset.

[0351] See also Fig.12 According to a flowchart of another method for transmitting HARQ feedback information shown in an exemplary embodiment, the above step 12 may include:

[0352] In step 1233, a physical resource block PRB index range of the current PDSCH resource is determined;

[0353] In step 1234, according to the seventh preset indication sub-information, the sum of the preset PRB index value of the current PDSCH resource and the starting position information of the preset HRAQ PUCCH resource is determined as the third reference PUCCH index information corresponding to the current PDSCH resource;

[0354] In step 1235, target PUCCH index information of the current PDSCH resource is determined according to the third reference PUCCH index information and the third preset offset.

[0355] In the embodiment of the present disclosure, the above steps 1233 and 1234 are similar to the above steps 1231 and 1232, except that, in the embodiment of the present disclosure, the PUCCH resource index information determined in step 1234 is used as reference PUCCH index information, i.e., third reference PUCCH index information. Further, according to the third reference PUCCH index information and a third preset offset preset by the system or base station, a target PUCCH index information corresponding to a PDSCH resource is determined.

[0356] In the embodiment of the present disclosure, the process of determining the target PUCCH index information may be as shown in the following formula (3):

[0357] n_PUCCH=n_PRB+N_PUCCH+offset formula (3)

[0358] Here, offset represents the third preset offset, which can be sent by the base station to the terminal through high-layer signaling such as RRC signaling, or PDCCH signaling.

[0359] The disclosed embodiment is applicable to the situation where the target PUCCH resource determined according to the above formula (2) is not suitable for transmitting HRAQ feedback information. For example, there are many resource fragments in the above PUCCH resource. Then the base station instructs the terminal to determine the offset PUCCH resource as the above target PUCCH resource according to the preset offset.

[0360] As described above, the base station may determine corresponding target PUCCH index information for each PDSCH resource scheduled by the MPDCCH according to any of the above situations based on the acquired HARQ PUCCH configuration information.

[0361] In step 13, HARQ feedback information of downlink data transmission carried by each PDSCH resource is loaded into the target PUCCH resource corresponding to the target PUCCH index information, and sent to the base station.

[0362] After the system completes the downlink data transmission carried by a PDSCH resource, the terminal generates corresponding HARQ feedback information, i.e., an ACK signal or a HACK signal, according to whether the received data is correct or not, and records the above HARQ feedback information in the target PUCCH resource indicated by the above target PUCCH index information, and sends it to the base station so that the base station determines whether to retransmit the downlink data carried by the above PDSCH based on the received HARQ feedback information.

[0363] In summary, in the present disclosure, a terminal in an MTC FDD system can determine target PUCCH index information of multiple PDSCH resources scheduled by the MPDCCH according to HARQ PUCCH configuration information and one MPDCCH information, which can effectively improve the efficiency of determining the target PUCCH index information. Accordingly, a base station in an MTC FDD system can schedule multiple PDSCH resources through one MPDCCH, avoiding sending one PDCCH information for each PDSCH resource, and effectively saving signaling overhead.

[0364] Correspondingly, the present 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.
