Description

Method and equipment for transmitting hybrid automatic repeat request (HARQ) information

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for transmitting harq information.

Background

Semi-persistent scheduling (SPS), or semi-persistent scheduling, periodically allocates resources of a PDSCH multiple times to a specific terminal device through a single downlink control signaling (PDCCH). The specific process is that the base station configures SPS resources for the terminal equipment through RRC signaling; after receiving the SPS configuration information, the terminal equipment also needs to receive a PDCCH for activating the SPS configuration; after the SPS configuration is activated, every period, the terminal equipment receives data in the SPS resource indicated by the PDCCH, and the base station does not need to issue the PDCCH to specify the allocated resource. The SPS scheduling has the characteristics of one-time allocation and multiple use, so that the PDCCH overhead is reduced. In addition, the SPS scheduling avoids the base station from sending scheduling information to the terminal equipment when downlink data is required, so that the time delay of downlink data transmission is reduced, and the service transmission requirement sensitive to time delay is met.

The NR system will support configuring N sets of SPS parameters for the terminal device to meet the service requirement of a Time Sensitive Network (TSN), wherein N is more than or equal to 2. In order to meet the arrangement of various service priorities, data streams with a plurality of periods and urgency priorities exist, so that a plurality of sets of SPS (semi-persistent scheduling) are required to be configured to meet different service characteristics; or, in order to meet the requirement of low delay characteristic of downlink data transmission, N sets of SPS parameters are configured, the configuration values are the same, but the activation times are different, and the base station can transmit the PDSCH on the nearest SPS resource in time.

In the prior art, for each PDSCH scheduled by each set of SPS, a terminal device sends hybrid automatic repeat request acknowledgement information (HARQ-ACK) on a PUCCH resource corresponding to each PDSCH.

If the value of N is large, that is, the base station configures and activates more SPS for the terminal device, the feedback method according to the prior art will cause the burden of HARQ-ACK feedback by the terminal device to be greatly increased, which affects the power efficiency of the terminal device and ultimately the overall efficiency of the system.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all 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 technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1(a) a schematic diagram of HARQ-ACK feedback for PDSCH during SPS configuration.

The HARQ-ACK contains Acknowledgement (ACK) and non-acknowledgement (NACK) information. And aiming at each PDSCH scheduled according to the SPS, the terminal equipment transmits corresponding ACK or NACK information in PUCCH resources corresponding to the PDSCH. The timing relationship between the PDSCH and the PUCCH is: and the terminal equipment receives the PDSCH related to SPS scheduling in a time slot n, and feeds back HARQ-ACK corresponding to the PDSCH in a time slot n + k.

Assuming that k is 4 as an example, fig. 1(a) is a schematic timing relationship diagram of a PDSCH of SPS and a PUCCH for transmitting HARQ-ACK when the SPS configuration period is 2 ms. In the figure, the SPS configuration period is 2ms, after acquiring the PDCCH activating SPS, the terminal device receives the PDSCH configured by SPS in time slots n, n +2, n +4, n +6, and … …, and correspondingly sends HARQ-ACK for feeding back the PDSCH configured by SPS in time slots n +4, n +6, and … ….

Fig. 1(b) is a diagram of HARQ-ACK feedback for PDSCH in multiple sets of SPS configurations.

According to the prior art, the terminal equipment transmits HARQ-ACK information for each PDSCH scheduled by SPS according to the configuration period of SPS. As shown in fig. 1(b) for example, N ═ 2:

the base station (network equipment) configures and activates two sets of SPS for the terminal equipment: SPS configuration 1 and SPS configuration 2. Wherein, the period of SPS configuration 1 is 2ms, and the PDCCH indication k activating SPS configuration 1 is 4, then the terminal device receives SPS PDSCH in time slots n, n +2, n +4, n +6, … …, and correspondingly sends HARQ-ACK feeding back PDSCH of SPS configuration 1 in time slots n +4, n +6, … …; the period of SPS configuration 2 is 1ms, the PDCCH indication k for activating SPS configuration 2 is 3, after acquiring the PDCCH for activating SPS configuration 2, the terminal device receives SPS configuration 2PDSCH in time slots n +1, n +2, n +3, and … …, and correspondingly sends HARQ-ACK for feeding back each PDSCH of SPS configuration 2 in time slots n +3, n +4, and … ….

If the value of N is large, that is, the base station configures and activates a large number of SPS for the terminal device, the feedback method of SPS PDSCH according to the prior art will cause the HARQ-ACK burden of the SPS PDSCH fed back by the terminal device to be increased greatly, which affects the power efficiency of the terminal device and ultimately the overall efficiency of the system.

In order to solve the problem that the terminal device is overloaded with HARQ-ACK information fed back by the SPS configuration due to multiple sets of SPS configurations, the present inventors have creatively proposed that the base station may not transmit the PDSCH in the multiple sets of SPS resources configured and activated for the terminal device at the same time in the following two situations.

In case one, to meet the low delay requirement of downlink transmission, the base station may configure and activate multiple sets of SPS for the terminal device. But most of the sets of SPS may be "spare" resources for shortening the time difference from the downlink traffic arrival time to the downlink transmission time, and the network device may transmit PDSCH on only a small fraction of the resources of the sets of SPS;

fig. 2(a) is a diagram illustrating the waiting time in SPS configuration.

As shown in fig. 2(a), if the base station only configures and activates 1 set of SPS with 4ms (and 4 slots) period for the terminal device. If the base station has a sudden downlink data transmission requirement, considering the time difference between the data arrival time position and the SPS PDSCH, the base station needs to wait for 4 time slots at most to transmit the downlink data on the activated SPS PDSCH resource, and the time delay of data transmission is large.

Fig. 2(b) is a schematic diagram of multiple sets of SPS configurations for latency reduction.

If the base station configures and activates 4 sets of SPS with 4ms period for the terminal equipment. As shown in fig. 2(b), the activation times of 4 sets of SPS differ by 1ms in sequence. If the base station has a downlink data transmission requirement suddenly, the downlink data can be transmitted on the PDSCH resource of the 4 sets of SPS closest to the downlink data transmission requirement, so that the low-delay requirement of downlink transmission can be met, and the waiting time is only 1ms at any data arrival time.

For this situation, the base station configures and activates multiple sets of SPS for the terminal device to reduce the time difference from the time of arrival of the downlink traffic to the time of downlink transmission. In actual transmission, only one set of resources in the activated SPS is used to transmit downlink data.

In case two, although the base station configures and activates multiple sets of SPS for the terminal device to support different service types, the terminal device does not support different service types simultaneously for a period of time. For example, when the terminal device receives the first type of service data, the second type of service data is not received at the same time. The first type of service data is, for example, ultra-high reliability low latency service data, and the second type of service data is, for example, VoIP service data. When the terminal device transmits the ultra-reliable low-delay service data, it may need to temporarily terminate the transmission of the VoIP service data.

In the solution of the present invention, the terminal device does not follow the prior art process of feeding back HARQ-ACKs of all PDSCHs of all activated SPS configurations. In the scheme of the invention, N sets of SPS configurations are regarded as a set, and for the SPS configurations in the set, the terminal equipment only feeds back HARQ-ACK of P sets of SPS configurations within a period of time. Wherein P < N. P is the number of SPS configurations used by the base station to transmit PDSCH over a period of time. Optionally, the P value is configurable; the length of the period of time may also be configurable. Therefore, compared with the prior art, the HARQ-ACK feedback load corresponding to the SPS configuration is greatly reduced, the problems that the transmission power efficiency of the terminal equipment is low and the system resource efficiency is low under the condition that a plurality of sets of SPS are configured and activated for the terminal equipment in the prior art can be solved, and the HARQ transmission performance is ensured.

Fig. 3 is a flowchart of an embodiment of the method of the present application.

Step 101, activating N sets of SPS configuration, wherein N is more than or equal to 1;

and the base station configures N sets of SPS resources for the terminal equipment through RRC signaling. And the terminal equipment receives the SPS configuration, activates the N sets of SPS configurations through the PDCCH, and receives data in corresponding resources according to the period of each SPS configuration.

Generally, the times of the N sets of SPS activations are not the same.

The SPS configuration includes parameters such as a configuration index number, a period T, HARQ process number, PUCCH resources, and a used MCS table. In this embodiment, the terminal device acquires a PDCCH for activating a semi-persistent scheduling configuration. Optionally, the PDCCH is scrambled with CS-RNTI.

It should be noted that, the applicant finds that the N sets of SPS configurations in the prior art are not occupied at the same time, and the base station only sends PDSCH of P sets of SPS, as described in the first and second cases.

102, setting parameters of downlink data and uplink data;

in step 102, a target time unit, a set period, and a target PDSCH are determined.

A target time unit and a set period are defined. And in the target time unit, performing HARQ-ACK feedback on the PDSCH within a set time period. That is, in the PDSCH in the set period, the corresponding HARQ-ACK feedback time is within a set target time unit.

A target PDSCH is defined. The target PDSCH is a PDSCH with P sets of SPS configurations and transmitted by signals in the set time interval, and P is less than N. The P sets of SPS configurations are part of the N sets of SPS configurations. Preferably, the N value has a preset corresponding relationship with 1 or more P values. For example, when N is 4, P is 2; when N is 3, P is 1. I.e., each N value has a P value corresponding thereto.

It should be noted that the value of P is agreed by signaling between the base station and the terminal device, or is preset by a unified protocol. The P value remains constant over a period of time.

When the above parameters are communicated by signaling, at least one of the following steps 102A, 102B, 102C is involved.

Step 102A, the k value is indicated by first indication information, and the first indication information is a downlink control signaling or a high-level signaling.

For example, the value of k is determined by "PDSCH-to-HARQ-timing-indicator" field in PDCCH, or by higher layer signaling "dl-DataToUL-ACK".

Further, for example, the value of k is determined by "PDSCH-to-HARQ-timing-indicator", which indicates that the value of k is one of the configured values of "dl-DataToUL-ACK".

And 102B, the P value is indicated by second indication information, and the second indication information is downlink control signaling or high-level signaling.

And 102C, the set time interval is indicated by third indication information, and the third indication information is downlink control signaling or high-level signaling.

Step 103, determining HARQ-ACK information;

the set time period satisfies: each of the N sets of SPS configurations includes at least one PDSCH for the set time period; in a preferred embodiment of the method of the present invention, said N sets of SPS configurations have the same configuration period; each of the N sets of SPS configurations includes one PDSCH within the set time period.

It should be noted that the set time period is determined by the network device and indicated to the terminal device, or the position of the set time period is preset in the communication protocol. For example, the time starting point of the nth set period in the system is the starting point of the downlink time unit M, and satisfies the following conditions: the network device can indicate the value of L to the terminal device through third indication information, and the time position of the Nth set time period can be determined according to the formula, or the value of L can be preset in a wireless communication protocol, wherein the length of the downlink time unit is 1 time slot or 1 sub-time slot.

Since at least one PDSCH of each of the N sets of SPS configurations is included within the set period, the length of the set period is related to the periodicity of each of the N sets of SPS configurations provided by the base station to the terminal device.

It should be noted that, in step 101, the activation of the N sets of SPS configurations may be completed by a downlink control signaling sent by the network device to the terminal device. For example, N sets of SPS configurations can be respectively activated through PDCCH scrambled by N CS-RNTIs. Steps 202A to C include downlink control signaling, and the relationship between the downlink control signaling and the downlink control information for activating SPS is not limited here.

And step 104, transmitting the HARQ-ACK information.

Within the target time unit, only HARQ-ACK information of the target PDSCH is transmitted. For example, the target time unit is 1 slot, that is, within 1 slot, there are 1 PUCCH including HARQ-ACK of P sets of SPS configurations.

It should be noted that, in the prior art, HARQ-ACK of N sets of SPS is fed back, and for the ith set of SPS configuration, M may be in a preset time period_iA PDSCH (M)_iNot less than 1) to the ith set of SPS feedback M_iAnd one HARQ-ACK.

In the prior art, each PDSCH of each 1 set of SPS corresponds to 1 HARQ-ACK information, if M of the ith set of SPS exists in a set time interval_iPDSCH, then needs to feed back in the target time unit according to the prior art

And HARQ-ACK information. According to the first and second conditions, not all the N sets of SPS have PDSCH actually transmitted in the set time interval, according to the scheme of the invention, the HARQ-ACK information corresponding to the SPS configuration in the target time unit only comprises the HARQ-ACK information of the target PDSCH in the set time interval, and the target PDSCH is the PDSCH of P sets of SPS configuration with signal transmission in the set time interval, P sets of SPS configuration<N, the feedback efficiency of HARQ-ACK information can be improved, the problems of low transmission power efficiency and low system resource efficiency of the terminal equipment in the prior art under the condition that a plurality of sets of SPS are configured and activated for the terminal equipment are solved, and the performance of HARQ transmission is ensured.

Preferably, the uplink control information includes indication information of the positions of the P sets of SPS configurations in the N sets of SPS configurations. That is, not only HARQ-ACK corresponding to P sets of SPS is fed back, but also information of which P sets of SPS configurations are N sets is fed back.

Fig. 4 is a flowchart of an embodiment of the method of the present application for a network device.

The method of the embodiment of the application is used for network equipment and comprises the following working steps:

step 201, sending a downlink control information group, wherein the downlink control information group comprises an indication for activating N sets of SPS configuration, and N is more than or equal to 1;

the downlink control information group includes 1 or more downlink control channels, and it should be noted that, typically, the activation times of the N sets of SPS configurations are different. For example, the network device activates N sets of SPS configurations respectively through N PDCCHs scrambled by CS-RNTIs.

Step 202, setting parameters of downlink data and uplink data;

in step 202, the network device determines a target time unit, a set time period, and a target PDSCH.

A set period and a target time unit are defined. And in the target time unit, performing HARQ-ACK feedback on the PDSCH within a set time period. That is, in the PDSCH in the set period, the corresponding HARQ-ACK feedback time is within a set target time unit.

A target PDSCH is defined. And the target PDSCH is a PDSCH with P sets of SPS configurations and transmitted by signals in the set time period, and P < N. The P sets of SPS configurations are part of the N sets of SPS configurations.

The set time period satisfies: each of the N sets of SPS configurations includes at least one PDSCH for the set time period.

In a preferred embodiment of the method of the present invention, said N sets of SPS configurations have the same configuration period; each of the N sets of SPS configurations includes one PDSCH within the set time period.

Alternatively, in a preferred embodiment of the method of the present invention, the N sets of SPS configurations have the same configuration period; and each set of the N sets of SPS configurations has the same number of PDSCHs contained in the set time period.

The P value, the target time unit and the set time period may be determined according to a predetermined rule or may be indicated by signaling. When indicated by means of signalling, involves at least one of the following steps 202A to 202F:

step 202A, receiving first indication information to obtain a k value;

the target time unit is the kth time unit calculated from the time unit of the end time of the set time interval.

When the network equipment receives a high-level signaling, the downlink control signaling comprises first indication information used for indicating the k value.

Step 202B, receiving second indication information to obtain a P value;

when the network equipment receives the high-level signaling, the high-level signaling comprises second indication information used for indicating the P value.

Step 202C, receiving third indication information and determining a set time period;

and when the network equipment receives the high-level signaling, the high-level signaling comprises third indication information for indicating the set time interval.

For example, the third indication information indicates that the time slot number modulo 10 by 0 is the starting point of a set period; the third indication information also indicates that the length of one set period is 10 ms.

Step 202D, sending first indication information for indicating a k value;

when the network equipment sends a downlink control signaling, the downlink control signaling contains first indication information for indicating the k value.

Step 202E, sending second indication information for indicating the P value;

and when the network equipment sends a downlink control signaling, the downlink control signaling comprises second indication information used for indicating the P value.

Step 202F, sending third indication information for determining a set time interval;

and when the network equipment sends the downlink control signaling, the downlink control signaling contains third indication information for indicating the set time interval.

For example, the third indication information indicates that the time slot number modulo 10 by 0 is the starting point of a set period; the third indication information also indicates that the length of one set period is 10 ms. Alternatively, the method for indicating the set period by the third indication information is the same as that described in 102C.

Thus, the time of the system is divided into a plurality of set time periods in sequence, such as: the 1 st and 2 nd periods, and the.

Step 203, the network equipment receives HARQ-ACK information;

and the network equipment receives the HARQ-ACK information of the target PDSCH through a target channel in the target time unit.

For example, the target channel is a PUCCH located within the target time unit.

And step 204, the network equipment determines the SPS configuration corresponding to the HARQ-ACK information.

And the network equipment receives uplink control information and identifies indication information (namely fourth indication information) of the positions of the P sets of SPS configuration in the N sets of SPS configuration.

Fig. 5 is a flowchart of an embodiment of the method of the present application for a terminal device.

The method of the embodiment of the application is used for the terminal equipment, and the working steps comprise:

301, receiving a downlink control information group, wherein the downlink control information group comprises an indication for activating N sets of SPS configuration, and N is more than or equal to 1;

after receiving the information for configuring and activating the N sets of SPS configurations, the terminal device continuously detects the PDSCH on the N sets of resources.

Step 302, setting parameters of downlink data and uplink data;

in step 302, the terminal device determines a target time unit, a set time period, and a target PDSCH.

Preferably, the N value has a preset corresponding relationship with 1 or more P values.

The P value, the target time unit and the set time period may be determined according to a predetermined rule, or may be indicated by means of signaling. When indicated by means of signalling, involves at least one of the following steps 302A-302C:

step 302A, receiving first indication information to obtain a k value;

And when the terminal equipment receives the downlink control signaling, the downlink control signaling comprises first indication information used for indicating the k value.

And when the terminal equipment receives the high-level signaling, the downlink control signaling comprises first indication information for indicating the k value.

Step 302B, receiving second indication information to obtain a P value;

and when the terminal equipment receives the downlink control signaling, the downlink control signaling contains second indication information for indicating the P value.

And when the terminal equipment receives the high-level signaling, the high-level signaling comprises second indication information which is used for indicating the P value.

Step 302C, receiving third indication information and determining a set time period;

and when the terminal equipment receives the downlink control signaling, the downlink control signaling contains third indication information for indicating the set time interval.

And when the terminal equipment receives the high-level signaling, the high-level signaling comprises third indication information for indicating the set time interval.

Step 303, the terminal equipment determines HARQ-ACK information;

the HARQ-ACK information configured corresponding to the SPS only comprises HARQ-ACK information of a target PDSCH within a set time interval; that is, the terminal device determines HARQ-ACK information of a target PDSCH of P sets of SPS configurations within a set period.

It should be noted that, when the terminal device receives the PDSCH configured by P sets of SPS, the terminal device may determine parameters of N sets of SPS configurations, and may determine resources corresponding to the N sets of SPS configurations. For example, the terminal device knows which resources the PDSCH of set 1 SPS configuration is detected on and which resources the PDSCH of set 2 SPS configuration is detected on. However, within the set period, the network device transmits downlink data on the PDSCH of the P sets of SPS at most, and the PDSCH transmitted by the network device on the SPS may not be normally detected on the terminal device side. It is assumed that resources in which the terminal can detect PDSCH data within a set period are resources of Q sets of SPS among N sets. When the value of Q is less than P, the terminal does not know to which SPS configurations the lost PDSCH corresponds. At this time, the terminal equipment still needs to determine the HARQ-ACK information of the target PDSCH of the P sets of SPS in the set time period, namely, the identified HARQ-ACK information of the target PDSCH is determined as ACK; determining HARQ-ACK information of the unidentified target PDSCH as NACK.

And step 304, the terminal equipment sends HARQ-ACK information.

In the target time unit, the terminal equipment sends uplink control information through a target channel, and the target channel only contains HARQ-ACK information of a target PDSCH.

For example, the target channel is a PUCCH located within the target time unit. It should be noted that, in the set time period, for a set of SPS configurations including multiple target PDSCHs, how the terminal device transmits HARQ-ACK is described. In the optimized embodiment of the application, if M corresponds to the ith set of SPS_iThe PDSCH occupies M according to HARQ-ACK information fed back by the target time unit and configured to the ith set of SPS_iAnd HARQ-ACK information. For example, if there are 4 PDSCHs in the 1 st set of SPS configuration within a set time, 4 bits are fed back for the SPS configuration.

Preferably, the uplink control information includes indication information of the positions of the P sets of SPS configurations in the N sets of SPS configurations (i.e., fourth indication information).

It should be noted that: in a special case, when a received signal is lost, the terminal device does not know which sets of SPS configurations the PDSCH information is lost, and at this time, the terminal device still needs to report HARQ-ACK of a target PDSCH of P sets of SPS configurations in a set time period, because the positions of unidentified X sets of SPS configurations in the N sets of SPS configurations cannot be determined, and default indication information can be used for the positions of the X sets of SPS configurations in the N sets of SPS configurations.

For example, when the base station is configured with N-4 and P-2, the base station transmits information on the PDSCH of SPS configurations 1 and 2, but the terminal device only detects PDSCH data on SPS configuration 2, but the terminal device still has to feed back 2 HARQ-ACKs. The terminal device tells the base station that the 1 st of the two HARQ-ACKs sent by itself is the HARQ-ACK of configuration 2 and the 2 nd is the invalid HARQ-ACK (it should be NACK), but the terminal device does not know that it corresponds to configuration 1, and the terminal device does not know whether the PDSCH of configuration 1 of the base station has sent data.

The base station expects the terminal equipment to send back 2 HARQ-ACKs, the 1 st one is the HARQ-ACK of configuration 1, and the 2 nd one is the HARQ-ACK of configuration 2. However, after the base station sees the feedback of the terminal device, it can be determined that the 1 st is HARQ-ACK of configuration 2, but configuration 1 cannot work effectively, for example, the transmission power is too low, or the coding rate is too high, so that the terminal device does not detect the presence of the above PDSCH, and the base station may subsequently reconfigure the parameters of configuration 1.

Fig. 6 is a diagram illustrating the location of the HARQ-ACK uplink control information.

Taking fig. 6 as an example, assuming that the set period is period 1, the base station transmits PDSCH on at most 1 set of the 4 sets of SPS configurations (SPS configuration 1/2/3/4) in period 1.

If the prior art is used, after the terminal equipment acquires the activation information of the 4 sets of SPS configurations, HARQ-ACK is fed back to PUCCHs respectively corresponding to the 4 sets of SPS configurations. For example, using the HARQ-ACK corresponding to the PDSCH of SPS configuration 1 on the PUCCH feedback slot n corresponding to SPS configuration 1 on slot n + 4; using HARQ-ACK corresponding to PDSCH of SPS configuration 2 on PUCCH feedback time slot n +1 corresponding to SPS configuration 2 on time slot n + 5; using HARQ-ACK corresponding to PDSCH of SPS configuration 3 on PUCCH feedback time slot n +2 corresponding to SPS configuration 3 on time slot n + 6; and HARQ-ACK corresponding to PDSCH of SPS configuration 4 on PUCCH feedback slot n +3 corresponding to SPS configuration 4 is used on slot n + 7.

By adopting the scheme of the invention, if P is 1, the terminal equipment does not need to feed back HARQ-ACK to all PDSCHs configured by 4 sets of SPS. But only needs to feed back HARQ-ACK of PDSCH corresponding to 1 set of SPS configuration. For example, in the 1 st period, the base station transmits downlink traffic data only in the PDSCH resource of SPS configuration 2, and the terminal device does not detect the PDSCH in SPS configurations 1, 3, and 4, but detects the PDSCH only in the resource of SPS configuration 2. Aiming at SPS configuration 1, 2, 3 and 4 in the 1 st time period, the terminal equipment only feeds back 1 HARQ-ACK message, thus solving the problems of low transmission power efficiency of the terminal equipment and low overall system efficiency in the prior art.

Further, in order to support the transmission of P HARQ-ACK messages on the target channel, the P sets of SPS are respectively corresponding to the PDSCH within the set time period, and belong to N sets of SPS, where P < N, there are the following solutions:

(1) the terminal equipment sends P pieces of HARQ-ACK information on a target channel, and the P pieces of HARQ-ACK information respectively correspond to PDSCHs of the SPS in the 1 st time period. The base station and the terminal device need to know where the time position of the 1 st time period is the same, and can determine which PDSCHs the HARQ-ACKs fed back by the target channel respectively correspond to. Optionally, the starting point of the 1 st period is the starting point of the time unit where the earliest SPS PDSCH in the N sets of SPS configurations is located; optionally, the length of the 1 st period is not less than the length between the starting PDSCH and the ending PDSCH, the starting PDSCH being the earliest initial SPS PDSCH among the N sets of PDSCHs, and the ending PDSCH being the latest initial SPS PDSCH among the N sets of PDSCHs. The initial SPS PDSCH refers to a first SPS PDSCH determined according to a PDCCH activating SPS configuration.

(2) The time location of the target channel needs to be determined. Optionally, the target channel is located in the kth time unit counted from the time unit where the last PDSCH in the P sets of SPS configurations is located in the 1 st time period. As shown in fig. 6, the time unit of the last PDSCH in the P sets of SPS configurations in period 1 is time slot n +1, and if k is 4, the target channel is located in time slot n + 5.

(3) During period 1, the base station transmits PDSCH on the most P-caps in SPS configuration 1/2/3/4. But the terminal device does not know on which set of SPS resources the base station transmits the PDSCH. According to the scheme of the invention, when the target channel feeds back the HARQ-ACK information of the PDSCH of the P sets of SPS in the 1 st period, the terminal equipment can carry the information of which sets of the N sets of SPS the P sets of SPS are carried on the target channel. Thus, if the base station sends downlink data in the SPS configuration 2, but the terminal device does not detect the downlink data in the SPS configuration 2, the terminal device indicates that NACK information currently carried in the target channel is irrelevant to any one of SPS configurations while indicating HARQ-ACK information sent by the target channel; if the base station sends the downlink data in the SPS configuration 2, the terminal equipment also detects the downlink data in the SPS configuration 2, and the terminal equipment indicates that the currently carried HARQ-ACK information is related to the SPS configuration 2 in the target channel while indicating the HARQ-ACK information sent by the target channel. After the base station detects that the target channel acquires the HARQ-ACK and the information of the SPS configuration index corresponding to the HARQ-ACK, the subsequent data transmission configuration can be adjusted to meet the service transmission requirement.

(4) After receiving the target channel, the base station can determine that the terminal device does not use the PUCCH resources corresponding to the target time of the other N-P sets of SPS except the P sets of SPS, and in a specific time period, the base station can allocate the PDSCH resources corresponding to the N-P sets of SPS to the other terminal device, which is beneficial to improving the resource efficiency of the system. In addition, the base station can also allocate the PUCCH resources corresponding to the N-P sets of SPS to other terminal equipment, which is beneficial to improving the resource efficiency of the system. Outside the target time, the base station may switch the position of the P sets of SPS. For example, the PDSCH of SPS configuration 2 of the base station transmits downlink data for a certain period of time, and the base station re-determines which SPS configuration to transmit downlink data for a certain period of time.

It should be noted that, in fig. 6, the PDSCH in the period 2 further needs another 1 target channel PUCCH to carry P harq-ACKs, the period 2 does not overlap with the period 1, and the response technique to the period 2 is the same as that in the period 1, which is not described again here.
