Description

HARQ-ACK enabling control method, device, equipment and storage medium
The present application claims priority from a patent application filed on 14/01/2021 under the name "HARQ-ACK enabling control method, apparatus, device, and storage medium" by the chinese patent office under the application number 202110049686.3, the entire contents of which are incorporated herein by reference.
Technical Field
The present application relates to the field of communications technologies, and in particular, to a HARQ-ACK enabling control method, apparatus, device, and storage medium.
Background
In order to improve transmission efficiency and reliability, a Hybrid Automatic Request-Acknowledgement (HARQ-ACK) feedback mechanism is widely used in a wireless communication system. In the HARQ-ACK feedback mechanism, the terminal device receives PDSCH (Physical Downlink Shared Channel) data sent by the base station, and if the decoding of the check code in the PDSCH data is incorrect, the terminal device feeds back non-acknowledgement (NACK) information to the base station, and if the decoding of the check code in the PDSCH data is correct, the terminal device feeds back Acknowledgement (ACK) information to the base station. And the base station retransmits the corresponding PDSCH according to the NACK information fed back by the terminal equipment until the ACK information fed back by the terminal equipment is received. The NACK information and the ACK information are collectively referred to as HARQ-ACK feedback information.
At present, the HARQ-ACK feedback mechanism is also applied to Multicast Broadcast Service (MBS), and when a base station broadcasts MBS Service data to a group of terminal devices, all the terminal devices in the group need to feed HARQ-ACK feedback information back to the base station. When receiving the NACK information fed back by any terminal device, the base station resends the MBS service data to the group of terminal devices until all terminal devices in the group feed back ACK information. When the number of terminal devices in the user group is large, the resource consumption of HARQ-ACK feedback is large.

The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a method, a device, equipment and a storage medium for controlling the enabling of HARQ-ACK, which are used for realizing the enabling control of the HARQ-ACK and reducing the resource consumption caused by unnecessary HARQ-ACK feedback.
The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not described again.
Fig. 1 is a flowchart of a HARQ-ACK enabling control method according to an embodiment of the present application. As shown in fig. 1, the method comprises the following specific steps:
step S101, before sending downlink service data to a group of terminal equipment, the network equipment sends downlink control information DCI containing HARQ-ACK enabling control information to the terminal equipment, wherein a specific information field in the DCI is used for carrying the HARQ-ACK enabling control information, and the HARQ-ACK enabling control information is used for indicating whether the terminal equipment feeds back the HARQ-ACK feedback information or not.
The HARQ-ACK enabling control information is used for enabling control on whether the terminal equipment feeds back the HARQ-ACK feedback information to the network equipment after receiving the service data in the HARQ-ACK feedback mechanism.
In this embodiment, enabling is defined as the network device requiring the terminal device to perform HARQ-ACK feedback, and disabling is defined as the network device not requiring the terminal device to perform HARQ-ACK feedback. And if the HARQ-ACK enabling control information is enabling information, the terminal equipment is required to feed back the HARQ-ACK feedback information to the network equipment after receiving the service data. And if the HARQ-ACK enabling control information is the de-enabling information, the terminal equipment does not feed back the HARQ-ACK feedback information to the network equipment after receiving the service data. The network equipment can flexibly switch the enabling (enable) and the disabling (disable) of the HARQ-ACK feedback mechanism, and realize the HARQ-ACK enabling control.
When applied to the MBS system, the service data is sent to the terminal equipment side by the base station side through the PDSCH. In order to reduce resource consumption of HARQ-ACK feedback and flexibly process various MBS services, the network device may not require any feedback from the terminal device for MBS services with low reliability requirement and large receiving amount.
In practical applications, HARQ-ACK feedback mechanisms are divided into two categories: an ACK/NACK based HARQ-ACK feedback mechanism and a NACK-only based HARQ-ACK feedback mechanism. In an ACK/NACK-based HARQ-ACK feedback mechanism, if a PDSCH check code is decoded correctly, the terminal equipment feeds back ACK information to the network equipment, and if the PDSCH check code is decoded incorrectly, the terminal equipment feeds back NACK information to the network equipment. In a NACK-only based HARQ-ACK feedback mechanism, the terminal equipment feeds back NACK information to the network equipment only when the PDSCH check code is decoded incorrectly, and does not feed back the NACK information in other conditions, namely the terminal equipment does not feed back ACK information to the network equipment after the PDSCH check code is decoded correctly, so that the resource consumption caused by HARQ-ACK feedback can be greatly reduced.
The HARQ-ACK enabling control method provided by the embodiment can be applied to an ACK/NACK-based HARQ-ACK feedback mechanism and a NACK-only-based HARQ-ACK feedback mechanism. When the method is applied to an ACK/NACK-based HARQ-ACK feedback mechanism, if enabling control information of the HARQ-ACK is de-enabling information, the terminal equipment does not need to feed back ACK information and NACK information to the network equipment, and if the enabling control information of the HARQ-ACK is enabling information, the terminal equipment needs to feed back the ACK information and the NACK information to the network equipment. When the method is applied to a NACK-only based HARQ-ACK feedback mechanism, if enabling control information of the HARQ-ACK is de-enabling information, the terminal equipment does not need to feed back NACK information to the network equipment, and if the enabling control information of the HARQ-ACK is enabling information, the terminal equipment needs to feed back the NACK information to the network equipment.
Currently, MBS systems support a group-shared group scheduling scheme (group-shared group scheduling scheme) of a PDCCH in common to all terminals, that is, in an MBS group, a group-common PDCCH scrambled by a G-RNTI (group-common RNTI) is supported to schedule a group-common PDSCH scrambled by the same G-RNTI for all terminals. That is, as shown in fig. 2, a group of terminal devices (e.g., UE1, UE2, and UE3 in fig. 2), a network device (e.g., a base station shown in fig. 2) schedules one PDSCH through one PDCCH.
In this embodiment, before sending downlink service data to a group of terminal devices, when a network device sends DCI to the terminal devices, the DCI carries HARQ-ACK enabling control information in a specific information field in the DCI, so as to send the HARQ-ACK enabling control information to the terminal devices to indicate whether the terminal devices feed back HARQ-ACK feedback information when receiving subsequently sent service data.
Step S102, the terminal equipment receives downlink control information DCI containing the enabling control information of the HARQ-ACK, and a specific information domain in the DCI is used for carrying the enabling control information of the HARQ-ACK.
The terminal equipment can receive DCI sent by the network equipment and analyze the enabling control information of the HARQ-ACK from a specific information domain of the DCI.
Step S103, the network device sends downlink service data to the terminal device.
And the network equipment sends downlink service data to the terminal equipment through the PDSCH.
And step S104, after the terminal equipment receives the downlink service data, determining whether to feed back HARQ-ACK feedback information to the network equipment according to the enabling control information of the HARQ-ACK.
After receiving the downlink service data, the terminal device may determine whether to feed back HARQ-ACK feedback information to the network device according to the HARQ-ACK enabling control information parsed from the DCI. According to the enabling control information of the HARQ-ACK, if the enabling control information of the HARQ-ACK is the disabling information, the terminal equipment does not need to feed back the HARQ-ACK feedback information to the network equipment, and therefore resource waste caused by unnecessary HARQ-ACK feedback is avoided.
In the embodiment of the application, the network equipment carries the enabling control information of the HARQ-ACK in the DCI to be sent to the terminal equipment, the terminal equipment determines whether to feed back the HARQ-ACK feedback information to the network equipment according to the enabling control information of the HARQ-ACK, so that whether the UE needs to feed back the HARQ-ACK feedback information to the network equipment can be flexibly controlled according to the enabling control information of the HARQ-ACK, the enabling control of the HARQ-ACK is realized, the resource consumption caused by unnecessary HARQ-ACK feedback can be reduced, in addition, the specific information domain in the DCI is used for carrying the enabling control information of the HARQ-ACK, no additional information domain needs to be added in the DCI, and the receiving performance of the PDCCH and the complexity of PDCCH detection cannot be influenced.
Fig. 3 is a flowchart of a HARQ-ACK enabling control method according to another embodiment of the present application. On the basis of the embodiment corresponding to fig. 1, in this embodiment, the network device may configure a specific information field used for carrying HARQ-ACK enabling control information in DCI, and state information corresponding to the HARQ-ACK enabling control information, where the HARQ-ACK enabling control information is enabling information or disabling information, the enabling information is used for instructing the terminal device to feed back HARQ-ACK feedback information, and the disabling information is used for instructing the terminal device not to feed back HARQ-ACK feedback information. As shown in fig. 3, the method comprises the following specific steps:
step S301, the network device configures a specific information field for carrying the HARQ-ACK enabling control information in the DCI and state information corresponding to the HARQ-ACK enabling control information.
The HARQ-ACK enabling control information is enabling information or disabling information, the enabling information is used for indicating the terminal equipment to feed back the HARQ-ACK feedback information, and the disabling information is used for indicating the terminal equipment not to feed back the HARQ-ACK feedback information.
In the MBS system, service data is transmitted by a network device to a terminal device through a PDSCH. In this embodiment, the downlink assignment DCI is used to carry HARQ-ACK enabling control information. Generally, the downlink allocation DCI format mainly includes DCI format 1_0, DCI format 1_1, and DCI format 1_ 2. The downlink allocation DCI includes the following 4 information fields: format indication information field (Identifier for DCI formats), transmission power control field (TPC command for scheduled PUCCH, abbreviated as TPC field), PUCCH resource indication field (PUCCH resource indicator, abbreviated as PRI field), and PDSCH-to-HARQ feedback timing field (PDSCH-to-HARQ _ feedback timing indicator, abbreviated as K1 field).
Wherein, the format indication information field occupies 1bit (bit), and the information head indicates whether the DCI is downlink allocation or uplink authorization. In the case that the DCI lengths of the multiple formats are the same, this indication bit may help the terminal device to distinguish the DCI formats. For example, the lengths of the DCI format 0_0 and the DCI format 1_0 are the same, but the DCI format 0_0 is an uplink grant DCI, and the DCI format 1_0 is a downlink assignment DCI, and the values of the format indication information fields in the two formats are different.
The TPC field occupies 2bits (bit) and includes 4 pieces of state information, and the values corresponding to different TPC fields of different state information are the scheduled PUCCH power control correction values for calculating the PUCCH power adjustment state (PUCCH power control adjustment state). The TPC domain occupies 2bits and comprises 4 pieces of state information, and each set of state information corresponds to one parameter value respectively. Table 1 shows an example of status information of a TPC field of a downlink assignment DCI where CRC is scrambled by a TPC-PUCCH-RNTI (Transmit Power Control-Physical Uplink Control Channel-RNTI) and a corresponding parameter value (see 38.213 protocol), which is specifically shown in table 1 below:
TABLE 1
State information of TPC field Parameter value (Unit dB)

The PUCCH resource indication field is used to indicate an index of a PUCCH resource for feedback in one resource set. In different DCI formats, the number of bits occupied by the PUCCH resource indication field may be different. For example, the PUCCH Resource indication field in DCI format 1_0 and DCI format 1_1 occupies 3bits, and values thereof are shown in table 2 below, and DCI format 1_2 may be configured as one of 1 to 3bits through higher layer information (e.g., RRC (Radio Resource Control), MAC CE (media access Control Element, MAC CE, etc.).
TABLE 2
PUCCH resource indication field (PRI field) Parameter value (index of PUCCH resource)
'000' 1
'001' 2
'010' 3
'011' 4
'100' 5
'101' 6
'110' 7
'111' 8
The PDSCH to HARQ feedback timing domain (K1 domain) is used to indicate when HARQ feedback is sent with respect to PDSCH transmissions. The number of bits occupied by the K1 field may be different in different DCI formats. For example, for DCI format 1_0, the K1 field occupies 3bits, and may take values of {1, 2, 3, 4, 5, 6, 7, 8 }. For the DCI format 1_1 and the DCI format 1_2, the bit number of the K1 field may be configured by higher layer information (e.g. RRC, MAC CE, etc.), and may be specifically configured as shown in table 3 below:
TABLE 3
Figure BDA0003010541110000201
In this embodiment, the network device may configure one or more information fields in the DCI as specific information fields for carrying HARQ-ACK enabling control information, and configure state information corresponding to the HARQ-ACK enabling control information.
In an optional implementation manner, in the MBS system, check codes of PDCCH scheduling information are all scrambled by G-RNTI, when the PDCCH scheduling information is scrambled by the G-RNTI, it can already be indicated that the scheduling is downlink scheduling, and a format indication information field originally used for indicating whether uplink or downlink during scheduling in DCI can be used for carrying HARQ-ACK enabling control information. In this embodiment, the format indication information field in the DCI may be configured as a specific information field for carrying HARQ-ACK enabling control information; and configuring the state information corresponding to the enabling information as first state information, and configuring the state information corresponding to the disabling information as second state information.
Illustratively, the Check code in the PDCCH scheduling information may be a Cyclic Redundancy Check (CRC) code, in the MBS system, the CRC code in the PDCCH scheduling information is scrambled by G-RNTI, and the value of the format indication information field of the DCI in the PDCCH scheduling information is HARQ-ACK enabling control information. The protocol may be modified to pre-agree.
The format indication information field is 1bit, and comprises two pieces of state information, wherein one piece of state information (first state information) can be used for representing enabling information, and the other piece of state information (second state information) can be used for representing disabling information.
In another optional embodiment, a transmission power control field (TPC field) in the DCI may be configured as a specific information field for carrying HARQ-ACK enabling control information; and configuring the state information corresponding to the de-enabling information as third state information, wherein the third state information is any one of all state information of the transmission power control domain.
In this embodiment, if the value of the transmission power control field is the third status information, it indicates that the HARQ-ACK enabling control information is the de-enabling information; and if the value of the transmission power control field is not the third state information, indicating that the HARQ-ACK enabling control information is enabling information, and the parameter value corresponding to the transmission power control field is a scheduling PUCCH power control correction value.
Wherein the third state information may be any one of state information included in the TPC field.
Illustratively, the TPC field occupies 2bits and includes 4 status messages, and the de-enabling message for HARQ-ACK enabling control may be indicated by pre-agreeing or configuring one of the status messages.
The pre-agreed mode is that state information of one TPC domain is pre-agreed in a protocol to indicate de-enablement information of HARQ-ACK enablement control, and extra signaling indication is not needed. The pre-configured manner can be notified to the terminal device by the network device through higher layer information (e.g. RRC, MAC CE, etc.): the state information of one TPC field indicates de-enable information of HARQ-ACK enable control.
For example, when the value of the predetermined TPC field is the status information '0', the parameter value corresponding to the TPC field is the de-enable information for the HARQ-ACK enable control; and when the value of the TPC domain is the state information '1', the corresponding parameter value of the TPC domain is the enabling information of the HARQ-ACK enabling control.
For example, based on the information of the TPC field shown in table 1, when the value of the TPC field is configured as state information '3', the corresponding parameter value of the TPC field may be de-enabled information for HARQ-ACK enabling control, so that when the TPC field is reduced by one state information, it is ensured as much as possible that the power of the PUCCH may still be adjusted up (corresponding to a parameter value of 1dB), adjusted down (corresponding to a parameter value of-1 dB), and kept unchanged (corresponding to a parameter value of 0 dB). The information of the configured TPC field is shown in table 4 below:
TABLE 4
State information of TPC field Parameter value (Unit dB)

3 HARQ-ADisabling information for CK enable control
In another optional embodiment, the PUCCH resource indication field in the DCI may be configured as a specific information field for carrying HARQ-ACK enabling control information; and configuring state information corresponding to the de-enabling information as fourth state information, wherein the fourth state information is any one of all state information of the PUCCH resource indication domain.
Optionally, the fourth state information is any one of idle state information of the PUCCH resource indication field.
Illustratively, the PUCCH resource indication field comprises a plurality of state information, when the number of PUCCH resources in the PUCCH resource set is less than the number of state information comprised by the PUCCH resource indication field, idle state information which is not used for indicating PUCCH resources exists, and the idle state information can be used for indicating the de-enabling information of HARQ-ACK. The state information used to indicate the PUCCH resources is referred to as becoming non-idle state information.
For example, in DCI format 1_0, the PUCCH resource indication field occupies 3bits and includes 8 pieces of status information. When the state information '010' and '101' is not used to indicate the PUCCH resource, then the state information '010' or '101' may be used to indicate de-enable information of HARQ-ACK enable control. Similarly, when the PUCCH resource indication field in DCI format 1_2 is configured to be 2bits, 4 pieces of status information are included. If the state information '10' is not used to indicate PUCCH resources, '10' may be used to indicate de-enable information of HARQ-ACK enable control.
The network device may also indicate the de-enabling information of the HARQ-ACK enabling control by pre-agreeing or configuring any one of the status information.
In this embodiment, if the value of the PUCCH resource indication field is the fourth state information, it indicates that the HARQ-ACK enabling control information is the de-enabling information; if the value of the PUCCH resource indication field is not the fourth state information, the HARQ-ACK enabling control information is indicated to be enabling information, and the parameter value corresponding to the PUCCH resource indication field is the index of the PUCCH resource.
In addition, the network device should try to avoid reusing state information already configured for carrying HARQ-ACK enabling control information for indicating PUCCH resources. If the state information for carrying the HARQ-ACK enabling control information is used to indicate a PUCCH resource, the PUCCH resource indication is invalid.
For example, when the PUCCH resource indication field in DCI format 1_1 is configured with 3bits, 8 pieces of state information are included. One state information, such as '111', pre-agreed or configured PUCCH resource indication field indicates de-enabling information of HARQ-ACK enabling control, and if this state is used to indicate PUCCH resources, the PUCCH resource indication is invalid. I.e. there are at most 7 PUCCH resource indications in one resource set. Similarly, the DCI format 1_2 may also be configured.
In another optional embodiment, a PDSCH-to-HARQ feedback timing domain (K1 domain) in DCI may be configured as a specific information domain for carrying HARQ-ACK enabling control information; and configuring state information corresponding to the de-enabling information into fifth state information, wherein the fifth state information is any one of all state information from the PDSCH to the HARQ feedback timing domain.
The number of bits occupied by the K1 field differs among DCI formats. Usually, the K1 field in the DCI format 1_0 occupies fixed 3bits, and the bit number occupied by the K1 field in the DCI format 1_1 and DCI format 1_2 is determined according to the number of configurations (denoted by I) in the K1 set, that is, the bit number occupied by the K1 field is equal to the number of bits occupied by the K1 set
Figure BDA0003010541110000231
In this embodiment, the disabling information of HARQ-ACK enabling control may be indicated by either one of the state information being agreed or configured in advance.
Exemplarily, for the DCI format 1_0, the disabling information for HARQ-ACK enabling control may be indicated by pre-agreeing or configuring any one of the state information. For the DCI format 1_1 and the DCI format 1_2, the disabling information for HARQ-ACK enabling control is indicated by either one of the state information by pre-engagement or configuration without changing the original bit number of the K1 field.
Optionally, the fifth state information is any one of idle state information of PDSCH to HARQ feedback timing domain.
For example, for DCI format 1_0, whose K1 field is 3bits, when '111' or '110' is idle state information, one of the state information may be used to indicate de-enabling information for HARQ-ACK enabling control; or one status information such as '111' indicating the de-enabling information of the HARQ-ACK enabling control is directly pre-agreed/configured, then '111' cannot be used to indicate the PDSCH-to-HARQ feedback timing or the indicated PDSCH-to-HARQ feedback timing is invalid, i.e. the remaining 7 status information can indicate the PDSCH-to-HARQ feedback timing.
For example, for DCI format 1_1 and DCI format 1_2, the same method as DCI format 1_0 is used to indicate the disable information for HARQ-ACK enabling control through an idle information state (e.g., '111' or '110'), or any state information (e.g., '111') may be directly pre-agreed/pre-configured to indicate the disable information for HARQ-ACK enabling control without changing the original bit number of the K1 field.
Optionally, for the DCI format 1_1 and DCI format 1_2, idle state information may also be added in the K1 field by changing the bit number of the K1 field, and one of the state information may be used to indicate de-enable information for HARQ-ACK enabled control.
Specifically, the number of preconfigured state information from the PDSCH to the HARQ feedback timing domain is taken as a first number, and the sum of the first number and a preset incremental value is calculated to obtain a second number; and calculating the bit number occupied by the PDSCH to the HARQ feedback timing domain according to the second quantity, so that the quantity of all state information which can be expressed by the PDSCH to the HARQ feedback timing domain is larger than the first quantity, and idle state information exists in all the state information from the PDSCH to the HARQ feedback timing domain.
Wherein the preset increment value is a positive integer greater than or equal to 1, preferably the preset increment value may be 1, so as to avoid that the PDSCH-to-HARQ feedback timing domain in DCI is too large. The first number is the number of preconfigured state information of PDSCH to HARQ feedback timing domain, and is alsoThe number of configurations in the K1 set (denoted by I). Illustratively, the bit number of the K1 field is first re-determined by adding 1 to the configuration number I in the K1 set:
Figure BDA0003010541110000241
and setting the upper limit of the bit number as: min
Figure BDA0003010541110000242
And then represents the de-enabling information of the HARQ-ACK enabling control by using one of the state information.
For example, when I ≧ 8, there is no idle status information, one status information (e.g., '111') indicating the de-enable information for HARQ-ACK enabled control can be directly pre-agreed or configured, and then this status information cannot be used to indicate PDSCH-to-HARQ feedback timing or the indicated PDSCH-to-HARQ feedback timing is invalid, i.e., the remaining 7 status information can indicate PDSCH-to-HARQ feedback timing.
When the value of I is less than 8, the K1 domain postamble can be used
Figure BDA0003010541110000243
Any one of the idle state information indicates the de-enable information of the HARQ-ACK enabled control: if I is 2, the total bit number of the K1 field is calculated to be

Then is back to
Figure BDA0003010541110000245
The individual state information, i.e., '10' or '11', may be used to indicate de-enable information of HARQ-ACK enable control. If I is 3, the total bit number of K1 field is calculated to be
Figure BDA0003010541110000246
Then is back to
Figure BDA0003010541110000247
The individual state information, i.e., '11', may be used to indicate de-enable information of HARQ-ACK enable control. If I is 6, the total bit number of K1 field is 3bit, then
Figure BDA0003010541110000248
The individual state information, i.e., '110' or '111', may be used to indicate de-enable information of HARQ-ACK enable control. Any one of the status information in the K1 field may also be pre-agreed or configured to indicate the de-enabling information of the HARQ-ACK enabling control, whether it is idle status information or not. In an alternative of this embodiment, if the value from the PDSCH to the HARQ feedback timing domain is the fifth state information, it indicates that the HARQ-ACK enabling control information is the de-enabling information; if the value from the PDSCH to the HARQ feedback timing domain is not the fifth state information, the HARQ-ACK enabling control information is indicated to be enabling information, and the parameter value corresponding to the PDSCH to the HARQ feedback timing domain is the PDSCH to HARQ feedback timing value.
In a second alternative of this embodiment, the PDSCH-to-HARQ feedback timing field (K1 field) in the DCI is configured as a specific information field for carrying HARQ-ACK enabling control information, and at the same time, the K1 field may still indicate PUCCH feedback resources, which improves the flexibility of HARQ-ACK enabling control. The fifth state information may be understood as an undetermined enable state, that is, when the DCI indicates the feedback resource using the state, the terminal needs to further determine according to the PUCCH resource indicated by the DCI, and the HARQ-ACK enable control information corresponding to the DCI is finally enabled or disabled.
In this second alternative, the overall process comprises the following steps 1-5:
step 1, the network equipment configures the uplink and downlink time slot configuration of a cell.
Illustratively, the network device may configure uplink and downlink timeslot information of the cell through a cell broadcast message or RRC.
And 2, the network equipment configures a set of all state information included from the PDSCH to the HARQ feedback timing domain (K1 domain), and configures one of the state information as fifth state information.
Optionally, if the network device does not configure the set of all state information included in the PDSCH to HARQ feedback timing domain (K1 domain), a protocol may also be adopted to default to a set of state information of one K1 domain.
The fifth status information may be one status information set by the network device or default status information. For example, when the base station indicates, through a higher layer, that the enabling/disabling of HARQ-ACK is allowed to be indicated through DCI, one state information in the K1 field may be indicated or defaulted as the fifth state information.
And 3, the network equipment sends the DCI scheduling information and the corresponding PDSCH data.
And 4, the terminal receives the DCI scheduling information and determines the HARQ-ACK enabling control information according to the DCI scheduling information.
Specifically, if the value from the PDSCH to the HARQ feedback timing domain is the fifth state information and the PUCCH resource corresponding to the value from the PDSCH to the HARQ feedback timing domain is an unavailable PUCCH resource, the HARQ-ACK enabling control information is de-enabling information.
If the value from the PDSCH to the HARQ feedback timing domain is the fifth state information and the PUCCH resource corresponding to the value from the PDSCH to the HARQ feedback timing domain is not the unavailable PUCCH resource, when the unavailable PUCCH resource exists in the PUCCH resource corresponding to the sixth state information from the PDSCH to the HARQ feedback timing domain, the HARQ-ACK enabling control information is enabling information; and when the PUCCH resources corresponding to the sixth state information from the PDSCH to the HARQ feedback timing domain do not have unavailable PUCCH resources, the HARQ-ACK enabling control information is de-enabling information.
Wherein the sixth state information includes state information except the fifth state information among all state information included in the PDSCH-to-HARQ feedback timing domain.
And if the value from the PDSCH to the HARQ feedback timing domain is not the fifth state information and the PUCCH resource corresponding to the value from the PDSCH to the HARQ feedback timing domain is the unavailable PUCCH resource, the HARQ-ACK enabling control information is the de-enabling information.
And if the value from the PDSCH to the HARQ feedback timing domain is not the fifth state information and the PUCCH resource corresponding to the value from the PDSCH to the HARQ feedback timing domain is not the unavailable PUCCH resource, the HARQ-ACK enabling control information is enabling information.
Optionally, the unavailable PUCCH resources satisfy at least one of:
including at least one downlink symbol, being a downlink time slot, a time domain and a distance between scheduled data PDSCHs being greater than a corresponding distance threshold, a time domain and a measurement channel overlap.
The distance threshold may be set and adjusted according to an actual application scenario, and is not specifically limited herein.
Exemplarily, the case that the PUCCH resource is unavailable may include the following cases:
1) the PUCCH resource contains at least one downlink symbol;
2) PUCCH resources are downlink time slots;
3) the distance between the PUCCH resource time domain and the scheduling data PDSCH is smaller than a corresponding distance threshold, and the terminal cannot finish PDSCH decoding and HARQ-ACK feedback;
for example, under the condition that the subcarrier spacing is 60KHz, the earliest time for the terminal to receive the PDSCH and feed back the HARQ-ACK is 24 symbols, and if the distance between the time domain of the PUCCH resource indicated by the scheduling DCI and the PDSCH is 1 slot, which is reduced to 14 symbols, the distance between the time domain of the PUCCH resource and the PDSCH of the scheduling data is too short, and the terminal cannot complete PDSCH decoding and HARQ-ACK feedback.
4) The PUCCH resource time domain overlaps with a terminal measurement GAP (measurement GAP).
The base station is configured to a measurement GAP, and during the GAP measurement period, the terminal cannot receive data and perform uplink feedback.
And 5, if the HARQ-ACK enabling control information is enabling information, the terminal feeds back HARQ-ACK feedback information to the network equipment according to the time slot offset corresponding to the PDSCH to the HARQ feedback timing domain.
Step S302, the network device determines HARQ-ACK enabling control information when transmitting downlink service data according to the current service requirement.
In practical application, different MBS services may have different requirements on transmission reliability, and the size of the transmission data amount may also be different. For the MBS service with lower reliability requirement and larger received data amount, the network device may set the HARQ-ACK enabling control information during transmitting the MBS service as the disabling information, without requiring the terminal device to feed back the HARQ-ACK feedback information.
In this step, the network device may determine HARQ-ACK enabling control information when transmitting downlink service data according to the current service requirement.
In addition, the network device sets which MBS services are transmitted corresponding to the HARQ-ACK enabling control information as the de-enabling information, and may perform configuration and adjustment according to the actual application scenario, which is not specifically limited herein.
Step S303, the network device sends PDCCH scheduling information to the terminal device, wherein the PDCCH scheduling information comprises DCI, and one domain in the DCI is used for carrying HARQ-ACK enabling control information.
In this embodiment, the DCI may be carried in the PDCCH scheduling information. And the network equipment transmits the DCI containing the HARQ-ACK enabling control information to the terminal equipment by transmitting the PDCCH scheduling information containing the DCI to the terminal equipment.
Step S304, the terminal equipment receives PDCCH scheduling information, and the PDCCH scheduling information comprises DCI.
After receiving the PDCCH scheduling information, the terminal device may extract DCI from the PDCCH scheduling information.
Step S305, the terminal equipment determines the HARQ-ACK enabling control information according to a specific information domain which is configured in advance and used for carrying the HARQ-ACK enabling control information and the state information corresponding to the HARQ-ACK enabling control information.
In this step, the terminal device may extract HARQ-ACK enabling control information from DCI according to a specific information field for carrying HARQ-ACK enabling control information in preconfigured DCI and state information corresponding to the HARQ-ACK enabling control information, and determine whether the HARQ-ACK enabling control information carried in the specific information field of DCI is enabling information or disabling information.
In an optional embodiment, the check code in the PDCCH scheduling information is scrambled by a group radio network temporary identity G-RNTI. The pre-configured specific information field for carrying the HARQ-ACK enabling control information is a format indication information field in the DCI.
In this step, if the value of the format indication information field in the DCI is the first state information, the HARQ-ACK enabling control information is enabling information; and if the value of the format indication information field in the DCI is the second state information, the HARQ-ACK enabling control information is the de-enabling information.
In an optional embodiment, the pre-configured specific information field for carrying the HARQ-ACK enabling control information is a transmission power control field in the DCI.
In this step, if the value of the transmission power control field in the DCI is the third state information, it is determined that the HARQ-ACK enabling control information is the de-enabling information. And if the value of the transmission power control field in the DCI is not the third state information, determining that the HARQ-ACK enabling control information is enabling information, and the parameter value corresponding to the transmission power control field is a scheduling PUCCH power control correction value.
In an optional embodiment, the pre-configured specific information field for carrying the HARQ-ACK enabling control information is a PUCCH resource indication field in the DCI.
In this step, if the value of the PUCCH resource indication field is the fourth state information, it is determined that the HARQ-ACK enabling control information is the de-enabling information. And if the value of the PUCCH resource indication field is not the fourth state information, determining that the HARQ-ACK enabling control information is enabling information, wherein the parameter value corresponding to the PUCCH resource indication field is the index of the PUCCH resource.
In an optional embodiment, the preconfigured specific information field for carrying the HARQ-ACK enabling control information is a PDSCH-to-HARQ feedback timing field in the DCI.
In this step, if the value from the PDSCH to the HARQ feedback timing domain is the fifth state information, it is determined that the HARQ-ACK enabling control information is the de-enabling information. And if the value from the PDSCH to the HARQ feedback timing domain is not the fifth state information, determining that the HARQ-ACK enabling control information is enabling information, and the parameter value corresponding to the PDSCH to the HARQ feedback timing domain is the PDSCH to HARQ feedback timing value.
After determining the HARQ-ACK enabling control information, whether to feed back the HARQ-ACK feedback information to the network equipment is determined according to the HARQ-ACK enabling control information.
In an optional embodiment, the preconfigured specific information field for carrying the HARQ-ACK enabling control information is a PDSCH-to-HARQ feedback timing field in the DCI. The terminal device may parse the DCI to obtain a value of the K1 field, and acquire time domain information of the PDSCH.
Exemplarily, taking the bit number of the PDSCH to the HARQ feedback timing domain (K1 domain) as 2bits as an example, the state information included in the K1 domain may be as shown in table 5 below, and exemplarily illustrated by taking "00" as fifth state information in table 5 as an example:
TABLE 5
Status information Parameter value (number of time slots) Whether or not to be the fifth status information
00 2 Is that
01 3
10 4
11 5
The step can be realized by the following steps 1) to 3):
step 1): determining whether the value of the PDSCH to HARQ feedback timing domain is fifth state information, and determining whether a PUCCH resource corresponding to the value of the PDSCH to HARQ feedback timing domain is an unavailable PUCCH resource.
Step 2): if the value from the PDSCH to the HARQ feedback timing domain is the fifth state information and the PUCCH resource corresponding to the value from the PDSCH to the HARQ feedback timing domain is not the unavailable PUCCH resource, acquiring sixth state information from the PDSCH to the HARQ feedback timing domain, wherein the sixth state information comprises state information except the fifth state information in all state information included from the PDSCH to the HARQ feedback timing domain.
After acquiring the sixth state information from the PDSCH to the HARQ feedback timing domain in step 2), step 3) is executed, and HARQ-ACK enabling control information is determined according to a PUCCH resource corresponding to the sixth state information.
3) And determining HARQ-ACK enabling control information according to PUCCH resources corresponding to the sixth state information.
Further, determining HARQ-ACK enabling control information according to the PUCCH resource corresponding to the sixth state information includes:
judging whether unavailable PUCCH resources exist in PUCCH resources corresponding to the sixth state information; if unavailable PUCCH resources exist in PUCCH resources corresponding to the sixth state information, determining the HARQ-ACK enabling control information as enabling information; and if the unavailable PUCCH resource does not exist in the PUCCH resource corresponding to the sixth state information, determining the HARQ-ACK enabling control information as de-enabling information.
Exemplarily, taking an unavailable PUCCH resource as a downlink slot, as shown in example 1 in fig. 4, if the state information of the K1 field of the DCI is '00', when the PDSCH is received in the slot n, the state information of the K1 field respectively corresponds to four slots (PUCCH resources) of n +2, n +3, n +4, n +5, it may be determined that the sixth state information of the K1 field includes '01', '10', '11', and the corresponding PUCCH resources are respectively the slots n +3, n +4, n + 5. When '00' is the fifth state information, since the PUCCH resource corresponding to the value of the K1 field is n +2 slot, which is an uplink slot, that is, is not an unavailable PUCCH resource, and all PUCCH resources corresponding to the sixth state information of the K1 field are uplink slots (which are not unavailable PUCCH resources), that is, there is no unavailable PUCCH resource in the PUCCH resource corresponding to the sixth state information of the K1 field, it may be determined that the HARQ-ACK enabling control information is de-enabling information, that is, the HARQ-ACK corresponding to the PDSCH received by the slot n is de-enabling, and the terminal does not need to feed back HARQ-ACK feedback information.
Exemplarily, taking an unavailable PUCCH resource as a downlink slot, as shown in example 2 in fig. 4, for a PDSCH received in slot n +1, the state information of the K1 field corresponds to four slots (PUCCH resources) of n +3, n +4, n +5, n +6, respectively, and if the state information of the K1 field of DCI is ' 11 ', it may be determined that the sixth state information of the K1 field includes ' 00 ', 01 ', ' 10 ', and the corresponding PUCCH resources are slots n +3, n +4, n +5, respectively. If '11' is the fifth state information, since the PUCCH resource corresponding to the value of the K1 domain is an n +6 slot, and is a downlink slot, that is, an unavailable PUCCH resource, it may be determined that HARQ-ACK enabling control information is de-enabling information, that is, HARQ-ACK corresponding to the PDSCH received at slot n +1 is de-enabling, and the terminal does not need to feed back HARQ-ACK feedback information.
Exemplarily, taking an unavailable PUCCH resource as a downlink slot as an example, as shown in example 3 in fig. 4, for a PDSCH received in slot n +1, the state information in the K1 field corresponds to four slots (PUCCH resources) of n +3, n +4, n +5, n +6, respectively, and if the state information in the K1 field indicated by the DCI is ' 00 ', it may be determined that the sixth state information in the K1 field includes ' 01 ', 10 ', and ' 11 ', and the corresponding PUCCH resources are slots n +4, n +5, and n +6, respectively. If '00' is the fifth state information, since the PUCCH resource corresponding to the value in the K1 domain is an n +3 slot, which is an uplink slot, that is, is not an unavailable PUCCH resource, and n +6 of the PUCCH resource corresponding to the sixth state information in the K1 domain is a downlink slot (which is an unavailable PUCCH resource), that is, an unavailable PUCCH resource exists in the PUCCH resource corresponding to the sixth state information in the K1 domain, it may be determined that HARQ-ACK enabling control information is enabling information, that is, HARQ-ACK corresponding to the PDSCH received in the slot n +1 is enabling information, and the terminal needs to feed back HARQ-ACK feedback information.
Step 4): and if the value from the PDSCH to the HARQ feedback timing domain is the fifth state information and the PUCCH resource corresponding to the value from the PDSCH to the HARQ feedback timing domain is the unavailable PUCCH resource, determining the HARQ-ACK enabling control information as the de-enabling information.
And step 5): and if the value from the PDSCH to the HARQ feedback timing domain is not the fifth state information and the PUCCH resource corresponding to the value from the PDSCH to the HARQ feedback timing domain is the unavailable PUCCH resource, determining the HARQ-ACK enabling control information as de-enabling information.
Step 6): and if the value from the PDSCH to the HARQ feedback timing domain is not the fifth state information and the PUCCH resource corresponding to the value from the PDSCH to the HARQ feedback timing domain is not the unavailable PUCCH resource, determining the HARQ-ACK enabling control information as enabling information.
According to the step 4) and the step 6), if the PUCCH resource corresponding to the value from the PDSCH to the HARQ feedback timing domain is unavailable, the HARQ-ACK enabling control information can be determined to be the de-enabling information.
For example, as shown in fig. 5, for a PDSCH received in slot n +1, taking the PUCCH resource corresponding to the value in the K1 field of DCI as slot n +6 as an example, and slot n +6 as a downlink slot, it may be determined that the PUCCH resource corresponding to the value in the K1 field of DCI is an unavailable PUCCH resource, and the HARQ-ACK enabling control information may be de-enabling information.
In this embodiment, the unavailable PUCCH resources satisfy at least one of:
including at least one downlink symbol, being a downlink time slot, a time domain and a distance between scheduled data PDSCHs being greater than a corresponding distance threshold, a time domain and a measurement channel overlap.
Optionally, the terminal device determines whether the PUCCH resource is an unavailable PUCCH resource, and may determine the value of the K1 field, the uplink and downlink timeslot ratio, and scheduling time domain information of the PDSCH.
Step S306, if the HARQ-ACK enabling control information is the disabling information, the terminal equipment does not feed back the HARQ-ACK feedback information to the network equipment.
In this embodiment, if the HARQ-ACK enabling control information is de-enabling information, the network device does not require the terminal device to feed back HARQ-ACK feedback information, and the terminal device does not need to feed back HARQ-ACK feedback information to the network device after receiving subsequent service data.
Step S307, if the HARQ-ACK enabling control information is enabling information, the terminal equipment feeds back HARQ-ACK feedback information to the network equipment.
In this embodiment, if the HARQ-ACK enabling control information is enabling information, the network device requests the terminal device to feed back HARQ-ACK feedback information, and the terminal device feeds back HARQ-ACK feedback information to the network device after receiving subsequent service data.
In another implementation manner of this embodiment, the network device may also flexibly enable or disable the HARQ-ACK enabling control, and configure the terminal device side by RRC to correspondingly enable or disable the HARQ-ACK enabling control.
Before sending downlink service data to a group of terminal devices and sending downlink control information DCI containing HARQ-ACK enabling control information to the terminal devices, the network device can enable HARQ-ACK enabling control and send enabling indication information of the HARQ-ACK enabling control to the terminal devices in response to the HARQ-ACK enabling control enabling instruction. And after receiving the enabling indication information of the HARQ-ACK enabling control, the terminal equipment enables the HARQ-ACK enabling control.
After the terminal equipment receives the downlink service data, if the enabling control of the HARQ-ACK is started, the terminal equipment determines whether to feed back the HARQ-ACK feedback information to the network equipment or not according to the enabling control information of the HARQ-ACK; and if the enabling control of the HARQ-ACK is closed, the terminal equipment feeds back HARQ-ACK feedback information to the base station.
After the HARQ-ACK enabling control is enabled, the network equipment can also close the HARQ-ACK enabling control in response to the HARQ-ACK enabling control enabling instruction and send closing indication information of the HARQ-ACK enabling control to the terminal equipment. And after receiving the closing indication information of the HARQ-ACK enabling control, the terminal equipment closes the enabling control of the HARQ-ACK.
For example, a way of adding a field dedicated to enable control information for indicating HARQ-ACK in DCI may increase the length of DCI, which may cause PDCCH reception performance to be degraded, and at the same time, increase the complexity of PDCCH detection.
According to the embodiment of the application, the specific information field in the downlink allocation DCI or the specific state information of the specific information field is used for indicating the enabling control information of the HARQ-ACK, the length of the DCI is not changed, the receiving performance of the PDCCH and the complexity of PDCCH detection are not influenced, the network equipment can flexibly switch the enabling or disabling state of the enabling control of the HARQ-ACK, the network equipment is more suitable for MBS service, and the flexibility of the enabling control of the HARQ-ACK is improved.
