Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The downlink control information transmission method provided by the embodiment of the application is described in detail below by means of specific embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in fig. 1, one of the step diagrams of the downlink control information transmission method in the embodiment of the present application is shown, where the method is applied to a terminal, and the method includes:
step 101: acquiring first downlink control information, wherein the first downlink control information is used for indicating a target hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) process of network scheduling, and the first downlink control information does not contain feedback scheduling indication information of hybrid automatic repeat request response information (HARQ-ACK) (Hybrid Automatic Repeat request-ACKnlwledgement, HARQ-ACK) of the target HARQ process;
in this step, the first downlink control information (Downlink Control Information, DCI) is used to indicate which of the hybrid automatic repeat request processes of the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) currently scheduled by the network. Specifically, the identification of the HARQ process, such as the process number of the HARQ process, may be indicated by a field in the first DCI, either explicitly or implicitly. For example, the indication is implicitly corresponding to the transmission resources of the first DCI and/or the scheduled PDSCH. Here, the manner in which the first DCI indicates the process identity of the scheduled target HARQ process is not restricted.
Step 102: and under the condition that the feedback state of the HARQ-ACK of the target HARQ process is enabled, acquiring feedback scheduling indication information of the HARQ-ACK of the target HARQ process according to the second downlink control information or preset information which is preset.
In the HARQ process received by the terminal, the feedback state of the HARQ-ACK of one part of the HARQ processes is enabled, and the feedback state of the HARQ-ACK of the other part of the HARQ processes is disabled. For the HARQ process with the feedback state of HARQ-ACK being de-enabled, the terminal does not need to acquire feedback scheduling indication information of the HARQ-ACK. Therefore, in this step, when it is determined that the feedback state of the HARQ-ACK of the target HARQ process is enabled, feedback scheduling indication information of the HARQ-ACK of the target HARQ process is acquired.
According to the downlink control information transmission method, a first DCI transmitted by a network device and obtained by a terminal is used for indicating a target HARQ process of network scheduling, and feedback scheduling indication information of HARQ-ACK of the target HARQ process is not contained in the first DCI, so that the formats of the first DCI are the same no matter whether the feedback state of the HARQ-ACK of the target HARQ process is enabled or disabled, on one hand, the problems that the feedback scheduling indication information of the HARQ-ACK is carried in DCI and the feedback scheduling indication information of the HARQ-ACK is disabled under the condition that the feedback state of the HARQ-ACK is enabled and the DCI does not carry the feedback scheduling indication information of the HARQ-ACK, so that the lengths of the DCI are different, the terminal blindly detects DCI formats of two lengths and the blind detection complexity of the terminal is high are avoided; on the other hand, the problem of low DCI indication efficiency caused by the fact that feedback scheduling indication information of the HARQ-ACK is carried in DCI no matter the feedback state of the HARQ-ACK is enabled or disabled is avoided; in addition, under the condition that the feedback state of the HARQ-ACK of the target HARQ process is determined to be enabled, further acquiring feedback scheduling indication information of the HARQ-ACK of the target HARQ process according to second DCI or preset information; the terminal can obtain the feedback scheduling indication of the HQRQ-ACK of the target HARQ process under the condition that the feedback state of the HARQ-ACK of the target HARQ process is enabled, so that the data of the target HARQ process is decoded according to the feedback scheduling indication of the HARQ-ACK.
Here, it should be noted that, when determining that the feedback state of the HARQ-ACK of the target HARQ process is disabled, the terminal further obtains the data of the target HARQ process carried on the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) sent by the network device, and analyzes the data of the target HARQ process.
Further, as an optional embodiment, after the first downlink control information is acquired in step 101, the method further includes:
determining a second resource for transmitting the second downlink control information according to a preset relation between a first resource for transmitting the first downlink control information and a second resource for transmitting the second downlink control information;
and acquiring the second downlink control information on the second resource, wherein the second downlink control information carries feedback scheduling indication information of HARQ-ACK of the target HARQ process.
Because the terminal needs to obtain the downlink control information through the blind detection process, if the terminal obtains the first DCI and the second DCI, the blind detection process is needed, and thus the blind detection complexity of the terminal is increased. Therefore, in this optional embodiment, the first resource for transmitting the first DCI and the second resource for transmitting the second DCI are set to satisfy the preset relationship, so that after the terminal blindly detects the first resource for transmitting the first DCI, the second resource for transmitting the second DCI can be determined, and the process of blindly detecting the second resource by the terminal is omitted, so that the problem of increasing complexity of blindly detecting the second resource for carrying the second DCI can be avoided. Specifically, the first resource may be a resource of the first PDCCH, and the second resource may be a resource of the second PDCCH.
Here, it should be noted that, after the terminal obtains the first DCI and determines, according to the first DCI, that the process identifier of the target HARQ process and the feedback state of the HARQ-ACK of the target HARQ process are enabled, the terminal obtains, on the one hand, the second DCI, thereby determining feedback scheduling indication information of the HARQ-ACK of the target HARQ process; on the other hand, acquiring data of a target HARQ process carried on a PDSCH and sent by network equipment, and analyzing the data of the target HARQ process; finally, the terminal sends the analysis result of the target HARQ process to the network equipment according to the feedback scheduling indication information of the HARQ-ACK of the target HARQ process; wherein the HARQ-ACK includes a positive acknowledgement (ACKnowledge, ACK), or a Negative acknowledgement (Negative ACKnowledge, NACK).
Optionally, if the terminal obtains feedback scheduling indication information of HARQ-ACK of the target HARQ process according to the second downlink control information, the feedback scheduling indication information of HARQ-ACK of the target HARQ process includes at least one of the following:
downlink allocation index;
PUCCH resource indication information;
PDSCH to HARQ-ACK timing information;
a PUCCH transmit power adjustment value;
PDSCH packet index.
Specifically, the downlink allocation index is used for determining the size of the HARQ-ACK feedback codebook and determining the position of the HARQ-ACK information of the target HARQ process in the HARQ-ACK codebook; the PUCCH resource indication information is used for determining PUCCH resources for feeding back HARQ-ACK in a time unit, and the timing information from PDSCH to HARQ-ACK is used for determining the position of the time unit fed back by the HARQ-ACK; the PUCCH transmission power adjustment value is used for determining an adjustment value of PUCCH transmission power; the PDSCH packet index is used for HARQ-ACK feedback of an indication of the PDSCH packet in which the target HARQ process is located when the PDSCH packet is a base packet.
Here, the HARQ-ACK feedback scheduling indication information is indication information for the HARQ-ACK feedback process, and the above listed information may be used as a typical example of the HARQ-ACK feedback scheduling indication, but the HARQ-ACK feedback scheduling indication is not limited thereto, and the information for the HARQ-ACK feedback process may be used as the HARQ-ACK feedback scheduling indication information in the present embodiment.
Further, as another optional embodiment, before the first downlink control information is acquired in step 101, the method further includes:
acquiring preset information preset by a network side, wherein the preset information comprises the following steps:
At least one HARQ process identity; the method comprises the steps of,
and the feedback scheduling indication information of the HARQ-ACK corresponding to each HARQ process identifier respectively.
In this alternative embodiment, one implementation is as follows: the preset information may be a mapping relationship, for example: the preset information comprises HARQ processes with process identifiers of a, b and c, and three groups of feedback scheduling indication information with the process identifier of A, B, C, wherein the HARQ process with the process identifier of a corresponds to the feedback scheduling indication information of group A; the HARQ process with the process identifier B corresponds to the feedback scheduling indication information of the group B; the HARQ process with the process identifier C corresponds to the feedback scheduling indication information of the group C; then, under the condition that the process identifier of the target HARQ process is B, the terminal can determine that the feedback scheduling indication information of the HARQ-ACK of the target HARQ process is B-group feedback scheduling indication information through the preset information.
In this optional embodiment, by determining feedback scheduling indication information of HARQ-ACK according to preset information, no matter whether the HARQ-ACK feedback state of the target HARQ process is an enabled state or a disabled state, the feedback scheduling indication information of HARQ-ACK is not carried in the first DCI, so that the lengths of formats of the first DCI are the same, thereby not affecting blind detection complexity of the terminal, and meanwhile, the indication efficiency of the first DCI can be ensured.
Optionally, the terminal obtains feedback scheduling indication information of HARQ-ACK of the target HARQ process according to preset information, where the feedback scheduling indication information of HARQ-ACK of the target HARQ process includes at least one of the following:
PUCCH resource indication information;
PDSCH to HARQ-ACK timing information;
PUCCH transmit power adjustment value.
Specifically, the PUCCH resource indication information is used for determining PUCCH resources for feeding back HARQ-ACK in a time unit, and the timing information from PDSCH to HARQ-ACK is used for determining the position of the time unit fed back by the HARQ-ACK; the PUCCH transmission power adjustment value is used to determine an adjustment value for PUCCH transmission power.
Also, the HARQ-ACK feedback scheduling indication information is indication information for the HARQ-ACK feedback process, and the above listed information may be used as a typical example of the HARQ-ACK feedback scheduling indication, but the HARQ-ACK feedback scheduling indication is not limited thereto, and the information for the HARQ-ACK feedback process may be used as the HARQ-ACK feedback scheduling indication information in the present embodiment.
On this basis, another implementation manner of the preset information may be: the preset information includes that the PUCCH resources of the feedback HARQ-ACK of each HARQ process are the resources of preset index numbers in the PUCCH resource group, the timing difference between PDSCH and HARQ-ACK feedback is a preset value, the PUCCH transmission power adjustment value is a preset value, the PDSCH packet index is a preset value, and the like. Optionally, the preset values may be configured for the terminal in advance by the network device, so that the length of the format of the first DCI is the same no matter the HARQ-ACK feedback state of the target HARQ process is an enabled state or a disabled state, so that the blind detection complexity of the terminal is not affected, and meanwhile, the indication efficiency of the first DCI may be ensured.
Further, as an optional embodiment, in step 101, the first downlink control information is acquired, and then the method further includes:
determining the feedback state of HARQ-ACK of the target HARQ process according to a preconfigured plurality of HARQ process sets and the process identification of the target HARQ process;
or alternatively, the process may be performed,
determining the feedback state of the HARQ-ACK of the target HARQ process according to the feedback state of the HARQ-ACK of the target HARQ process carried in the first downlink control information;
the feedback state of the HARQ-ACK of the target HARQ process comprises the following steps: enable, or disable.
Specifically, in the case that the feedback state of the HARQ-ACK of the target HARQ process is determined according to the preconfigured multiple HARQ process sets and the process identifier of the target HARQ process, the network device configures the multiple HARQ process sets for the terminal in advance, and specifically, the configuration process of the HARQ process sets may be: setting the process number of each HARQ process of which the feedback state of the HARQ-ACK is disabled in a first HARQ process set, and setting the process number of each HARQ process of which the feedback state of the HARQ-ACK is disabled in a second HARQ process set. After the terminal acquires the first DCI and determines the process identifier of the target HARQ process according to the first DCI, the terminal determines the HARQ process set to which the target HARQ process belongs, so that the feedback state of the HARQ-ACK of the target HARQ process is determined according to the feedback state of the HARQ-ACK of the HARQ process set.
Of course, the feedback state of the HARQ-ACK of the target HARQ process may also be directly carried in the first DCI, so that after the terminal obtains the first DCI, the feedback state of the HARQ-ACK of the target HARQ process may be determined. Here, there is no constraint on the manner in which the terminal determines whether the HARQ-ACK feedback state of the target HARQ process is the enabled state or the disabled state.
According to the downlink control information transmission method, a terminal acquires first downlink control information, wherein the first downlink control information is used for indicating a target hybrid automatic repeat request (HARQ) process of network scheduling, and feedback scheduling indication information of hybrid automatic repeat request response (HARQ-ACK) of the target HARQ process is not included in the first downlink control information; and under the condition that the feedback state of the HARQ-ACK of the target HARQ process is enabled, acquiring feedback scheduling indication information of the HARQ-ACK of the target HARQ process according to the second downlink control information or preset information which is preset. On the one hand, the problem that the terminal blindly detects DCI formats with two lengths and the blind detection complexity of the terminal is high because the DCI carries the feedback scheduling indication information of the HARQ-ACK under the condition that the feedback state of the HARQ-ACK is enabled and does not carry the feedback scheduling indication information of the HARQ-ACK under the condition that the feedback state of the HARQ-ACK is disabled is avoided; on the other hand, the problem of low DCI indication efficiency caused by the fact that feedback scheduling indication information of the HARQ-ACK is carried in DCI no matter the feedback state of the HARQ-ACK is enabled or disabled is avoided; in still another aspect, it is ensured that the terminal can obtain a feedback scheduling indication of HQRQ-ACK of the target HARQ process when a feedback state of HARQ-ACK of the target HARQ process is enabled, thereby implementing decoding of data of the target HARQ process according to the feedback scheduling indication of HARQ-ACK.
As shown in fig. 2, a second step of a downlink control information transmission method according to an embodiment of the present application is shown, where the method is applied to a network device, and the method includes:
step 201, sending first downlink control information, where the first downlink control information is used to indicate a target HARQ process of network scheduling, and the first downlink control information does not include feedback scheduling indication information of HARQ-ACK of the target HARQ process.
In this embodiment, feedback scheduling indication information of HARQ-ACK of the target HARQ process is included in the middle of the first DCI, so that the format length of the first DCI is the same no matter whether the HARQ-ACK feedback state of the HARQ process is enabled or disabled, so that complexity of blind detection of resources carrying downlink control information by the terminal is reduced, and indication efficiency of the DCI is improved.
Further, as an optional embodiment, in case that the feedback state of the HARQ-ACK of the target HARQ process is enabled, second downlink control information is sent, where the second downlink control information carries feedback scheduling indication information of the HARQ-ACK of the target HARQ process.
Because the feedback scheduling indication information of the HARQ-ACK of the target HARQ process is not carried in the first DCI, and in the case that the feedback state of the HARQ-ACK of the target HARQ process is enabled, the terminal needs to feed back the relevant information of the target HARQ process to the network device according to the feedback scheduling indication information of the HARQ-ACK, in this optional embodiment, the network device sends the first DCI to the terminal, and in the case that it is determined that the feedback state of the HARQ-ACK of the target HARQ process is enabled, the network device further sends the feedback scheduling indication information of the HARQ-ACK carrying the target HARQ process to the terminal.
Optionally, a preset relationship is satisfied between the first resource for transmitting the first downlink control information and the second resource for transmitting the second downlink control information.
Because the terminal needs to obtain the downlink control information through the blind detection process, if the terminal obtains the first DCI and the second DCI, the blind detection process is needed, and thus the blind detection complexity of the terminal is increased. Therefore, in this optional embodiment, the first resource for transmitting the first DCI and the second resource for transmitting the second DCI are set to satisfy the preset relationship, so that after the terminal blindly detects the first resource for transmitting the first DCI, the second resource for transmitting the second DCI can be determined, and blind detection of the second resource by the terminal is avoided, so that the problem of increased complexity of blind detection of the second resource for carrying the second DCI can be avoided. Specifically, the first resource may be a resource of the first PDCCH, and the second resource may be a resource of the second PDCCH.
Further, as an optional embodiment, in step 201, before sending the first downlink control information, the method further includes:
transmitting preset information of preset configuration, wherein the preset information comprises the following steps:
at least one HARQ process identity; the method comprises the steps of,
And the feedback scheduling indication information of the HARQ-ACK corresponding to each HARQ process identifier respectively.
In this alternative embodiment, one implementation is as follows: the preset information may be a mapping relationship, for example: the preset information comprises HARQ processes with process identifiers of a, b and c, and three groups of feedback scheduling indication information with the process identifier of A, B, C, wherein the HARQ process with the process identifier of a corresponds to the feedback scheduling indication information of group A; the HARQ process with the process identifier B corresponds to the feedback scheduling indication information of the group B; the HARQ process with the process identifier C corresponds to the feedback scheduling indication information of the group C; then, under the condition that the process identifier of the target HARQ process is B, the terminal can determine that the feedback scheduling indication information of the HARQ-ACK of the target HARQ process is B-group feedback scheduling indication information through the preset information. Another implementation is: the preset information includes that the PUCCH resources of the feedback HARQ-ACK of each HARQ process are the resources of preset index numbers in the PUCCH resource group, the timing difference between PDSCH and HARQ-ACK feedback is a preset value, the PUCCH transmission power adjustment value is a preset value, the PDSCH packet index is a preset value, and the like.
According to the downlink control information transmission method, the network equipment sends first DCI to the terminal, the first DCI is used for indicating a target HARQ process of network scheduling, and feedback scheduling indication information of HARQ-ACK of the target HARQ process is not contained in the first DCI. The lengths of the first DCI are the same, and the problems that the complexity of blind detection of the terminal is high due to different lengths of the DCI because the first DCI does not comprise the HARQ-ACK feedback scheduling indication information when the HARQ-ACK feedback state of the target HARQ process is enabled and the DCI carries the HARQ-ACK feedback scheduling indication information and the indication efficiency of the DCI is low due to the fact that the HARQ-ACK feedback state is enabled or disabled are avoided.
As shown in fig. 3, a third step of the downlink control information transmission method according to the embodiment of the present application is shown, where the method is applied to a terminal, and the method includes:
step 301: acquiring third downlink control information, wherein the third downlink control information is used for indicating a target hybrid automatic repeat request (HARQ) process scheduled by a network;
wherein, when the feedback state of the hybrid automatic repeat request acknowledgement information HARQ-ACK of the target HARQ process is enabled, the first field of the third downlink control information is used to indicate feedback scheduling indication information of the HARQ-ACK of the target HARQ process;
and in the case that the feedback state of the HARQ-ACK of the target HARQ process is disabled, the first field of the third downlink control information is used for indicating the first information.
Alternatively, the first information may be information for improving the performance of the HARQ process.
It should be noted that, the feedback state of HARQ-ACK is that the data transmission of the disabled HARQ process cannot acquire the HARQ retransmission combining gain based on the HARQ-ACK demodulation result. To ensure that the performance of the HARQ process with the feedback state of HARQ-ACK disabled is comparable to the performance of the HARQ process with the feedback state of HARQ-ACK enabled, a performance boost mechanism may be employed for the HARQ process with the feedback state of HARQ-ACK disabled. For different performance enhancing mechanisms, the network device is required to indicate a certain amount of control information to the terminal. In the case that the feedback state of the HARQ-ACK of the target HARQ process is disabled, the first field in the third DCI format may be used to indicate control information for improving the data transmission performance of the HARQ process. According to different performance enhancing mechanisms, the control information indicated by the network device to the UE is different.
According to the downlink control information transmission method, according to the feedback state of the HARQ-ACAK of the target HARQ process, the information indicated by the first field of the third DCI is made different, so that the indication efficiency of DCI is improved, and when the feedback state of the HARQ-ACK of the target HARQ process is enabled, the feedback scheduling indication information of the HARQ-ACK of the target HARQ process is indicated by the first field of the third DCI, so that the terminal can feed back the relevant information of the target HARQ process to the network equipment according to the feedback scheduling indication information. And under the condition that the feedback state of the HARQ-ACK of the target HARQ process is de-enabled, the data transmission performance is improved through the first information, so that the performance of the HARQ process with the feedback state of the HARQ-ACK being de-enabled is equivalent to that of the HARQ process with the feedback state of the HARQ-ACK being enabled.
Optionally, the feedback scheduling indication information of the HARQ-ACK of the target HARQ process includes at least one of the following:
downlink allocation index;
PUCCH resource indication information;
PDSCH to HARQ-ACK timing information;
a PUCCH transmit power adjustment value;
PDSCH packet index.
Optionally, the first information includes: and requesting uplink control information and/or a time resource format occupied by the data of the target HARQ process.
Wherein the uplink control request includes at least one of:
a statistical result of downlink data demodulation;
channel quality indication;
increasing/decreasing modulation coding mode indication;
aperiodic HARQ-ACK;
a power adjustment indication.
On the one hand, for the HARQ process with the feedback state of HARQ-ACK being disabled, the network device cannot learn the demodulation result of the physical layer data of the terminal, and if the terminal fails to demodulate the physical layer data, the terminal can only feed back the demodulation failure information to the network device at the radio link control (Radio Link Control, RLC) layer. If the downlink authorization scheduling result of the network device to the terminal is not matched with the actual channel condition of the terminal, the demodulation result of the physical layer data of the terminal is continuously wrong, or the physical layer data scheduling result of the terminal is too conservative, and finally the overall efficiency of the system is low. The statistical value of the downlink demodulation result is used as new uplink control information (Uplink Control Information, UCI), so that the network equipment can judge the scheduling result of the HARQ process which is disabled by the feedback of the previous HARQ-ACK, and determine the subsequent scheduling adjustment, so that the downlink authorized scheduling result is more matched with the actual channel condition of the terminal. For example, the statistical result of the downlink data demodulation may be a correct proportion of the data demodulation within the preset duration, or a proportion of the data demodulation error within the preset duration, and the expression form of the statistical result of the downlink data demodulation is not limited.
Or the terminal feeds back the data expected modulation coding mode difference value, the measured channel quality indication, the expected increase/decrease modulation coding mode, the aperiodic HARQ-ACK, the power adjustment request and other scheduling adjustment indicated values to the network equipment as new UCI, so that the base station can judge the scheduling result of the HARQ process with the feedback state of the previous HARQ-ACK being de-enabled, determine the subsequent scheduling adjustment and enable the downlink authorization scheduling result to be more matched with the actual channel condition of the terminal.
On the other hand, for HARQ processes in which the feedback state of HARQ-ACK is disabled, demodulation performance of data can be improved by repeating transmission a plurality of times. To obtain more time diversity gain, the HARQ process data may be repeatedly transmitted in discrete time units. The first DCI is used as scheduling indication information of a target HARQ process, and resources occupied by target HARQ process data in time are required to be indicated. As described above, in the case where the feedback state of the HARQ-ACK of the target HARQ process is disabled, the first field in the first DCI format may be used to indicate which discrete time units in time the data retransmission is located. Optionally, the network device presets a plurality of time resource patterns occupied by the repeatedly transmitted data, the first DCI indicates a time resource occupied by the first transmitted data of the target HARQ process, and indicates a time resource pattern occupied by the repeatedly transmitted data, so that the terminal determines the time resource pattern occupied by the data of the target HARQ process. In the case that the feedback state of the HARQ-ACK of the target HARQ process is disabled, a first field in the first DCI format may be used to indicate a time resource pattern occupied by data of the target HARQ process.
Further, as an optional embodiment, after the third downlink control information is obtained in step 301, the method further includes:
determining the feedback state of HARQ-ACK of the target HARQ process according to a preconfigured plurality of HARQ process sets and the process identification of the target HARQ process;
or alternatively, the process may be performed,
and determining the feedback state of the HARQ-ACK of the target HARQ process according to the feedback state of the HARQ-ACK of the target HARQ process carried in the third downlink control information.
Specifically, in the case that the feedback state of the HARQ-ACK of the target HARQ process is determined according to the preconfigured multiple HARQ process sets and the process identifier of the target HARQ process, the network device configures the multiple HARQ process sets for the terminal in advance, and specifically, the configuration process of the HARQ process sets may be: setting the process number of each HARQ process of which the feedback state of the HARQ-ACK is disabled in a first HARQ process set, and setting the process number of each HARQ process of which the feedback state of the HARQ-ACK is disabled in a second HARQ process set. After the terminal acquires the first DCI and determines the process identifier of the target HARQ process according to the first DCI, the terminal determines the HARQ process set to which the target HARQ process belongs, so that the feedback state of the HARQ-ACK of the target HARQ process is determined according to the feedback state of the HARQ-ACK of the HARQ process set.
Of course, the feedback state of the HARQ-ACK of the target HARQ process may also be directly carried in the first DCI, so that after the terminal obtains the first DCI, the feedback state of the HARQ-ACK of the target HARQ process may be determined. Here, there is no constraint on the manner in which the terminal determines whether the HARQ-ACK feedback state of the target HARQ process is the enabled state or the disabled state.
Optionally, the feedback scheduling indication information of the HARQ-ACK of the target HARQ process includes at least one of the following:
downlink allocation index;
PUCCH resource indication information;
PDSCH to HARQ-ACK timing information;
a PUCCH transmit power adjustment value;
PDSCH packet index.
Specifically, the downlink allocation index is used for determining the size of the HARQ-ACK feedback codebook and determining the position of the HARQ-ACK information of the target HARQ process in the HARQ-ACK codebook; the PUCCH resource indication information is used for determining PUCCH resources for feeding back HARQ-ACK in a time unit, and the timing information from PDSCH to HARQ-ACK is used for determining the position of the time unit fed back by the HARQ-ACK; the PUCCH transmission power adjustment value is used for determining an adjustment value of PUCCH transmission power; the PDSCH packet index is used for HARQ-ACK feedback of an indication of the PDSCH packet in which the target HARQ process is located when the PDSCH packet is a base packet.
Here, the HARQ-ACK feedback scheduling indication information is indication information for the HARQ-ACK feedback process, and the above listed information may be used as a typical example of the HARQ-ACK feedback scheduling indication, but the HARQ-ACK feedback scheduling indication is not limited thereto, and the information for the HARQ-ACK feedback process may be used as the HARQ-ACK feedback scheduling indication information in the present embodiment.
In the downlink control information transmission method of the embodiment of the present application, if the terminal determines that the feedback state of the HARQ-ACK of the target HARQ process is the enabled state, the terminal determines a feedback scheduling indication of the HARQ-ACK of the target HARQ process according to the first field of the third DCI; if the terminal determines that the feedback state of the HARQ-ACK of the target HARQ process is the disabling state, the terminal determines information for improving the data transmission reliability of the target HARQ process according to the first field of the third DCI, wherein the information comprises any information such as an uplink control information request, a time resource pattern occupied by the data of the target HARQ process and the like. In this way, whether the feedback state of the HARQ-ACK of the target HARQ process is the enabled state or the disabled state, the length of the third DCI format is the same, the blind detection complexity of the terminal is not affected, and the indication efficiency of the third DCI can be ensured.
