Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a hybrid automatic repeat request feedback method for activating multiple semi-persistent schedules.
Background
Semi-Persistent Scheduling (SPS) allows PDSCH or PUSCH resources to be periodically allocated to a specific terminal device through one physical downlink control channel Scheduling, unlike transmitting physical downlink control information to a terminal device (UE) once per PDSCH or PUSCH Scheduling in dynamic Scheduling. A network device (e.g., a base station) specifies a radio resource (referred to herein as an SPS resource) used by a terminal device through a PDCCH, and the terminal device transmits or receives data using the SPS resource every one cycle. The network device does not need to issue a PDCCH to specify the allocated resources. Due to the 'one-time allocation and multiple-time use' characteristic of SPS scheduling, the PDCCH overhead is reduced. In the current system, at most one SPS is configured for the terminal equipment in one cell group, and the parameters of one SPS configuration comprise the period, the number of HARQ processes, PUCCH resources and the used MCS table.
The SPS configuration information is configured to the terminal equipment by the network equipment through RRC signaling. The minimum value of the period of the SPS configuration is 10 ms. After the terminal device receives the configuration information, the corresponding resource cannot be used immediately. Only after the network device activates SPS configuration through the PDCCH, the terminal device receives or transmits data in the corresponding resource according to the period of SPS configuration. And if the terminal equipment receives an indication that the network equipment releases the SPS configuration through the PDCCH, the terminal equipment stops receiving or sending data in the corresponding resources of the SPS configuration.
For a service of a Time Sensitive Network (TSN), there are data streams with multiple periods and priority levels of urgency, and while supporting an aperiodic emergency service, the TSN needs to support a service with a low delay requirement. Traffic in a TSN network may not be an integer multiple of symbols, slots, or subframes. Therefore, in one aspect, the NR system will support configuring multiple SPS parameters for the terminal device to meet the traffic demand of the TSN, and the parameters of the multiple SPS can be configured independently. The terminal device is configured with a plurality of SPS, for example, via a plurality of independent SPS configuration information elements. On the other hand, the NR system will also likely support a service type with a short configuration period for the terminal device. For example, the SPS support period is 2 symbols, 7 symbols, or 1 slot.
The terminal equipment supports a plurality of configuration parameters for SPS scheduling, and the terminal equipment supports the SPS with a small configuration period, which causes the problem that the uplink signaling burden is heavy when the terminal equipment feeds back the HARQ-ACK of the PDSCH configured by the SPS. To overcome this problem, a NACK-only feedback mechanism may be introduced. The NACK-only feedback mechanism is a mechanism in which the terminal device feeds back NACK information on resources corresponding to the PDSCH only when reception of the downlink PDSCH fails, and does not feed back ACK information corresponding to the PDSCH when reception of the downlink PDSCH succeeds. The network device does not receive the NACK information fed back by the terminal device on the resource corresponding to the PDSCH, that is, the PDSCH is considered to be correctly received.
The PUCCHs used for transmitting the SPS configured PDSCH are typically PUCCH format 0 and PUCCH format 1, which can only accommodate 1-2 bits of information, if the terminal device is configured with NACK-only feedback. If the terminal equipment feeds back NACK to the PDSCH of the SPS, other uplink control information may be required to be sent, if the terminal equipment discards the NACK information of the SPS, the network equipment can cause the PDSCH of the SPS to be considered to be correctly received by the terminal equipment and does not schedule data retransmission, the reliability of SPS configuration is influenced, and particularly when the configuration is applied to URLLC service, a service target cannot meet the requirement; if the terminal device discards other uplink control information, the overall efficiency of the system will be reduced.

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 some 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 technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of configured PUCCH time overlapping of multiple SPS.
If the network equipment receives the PDSCH according to the SPS configuration in the time slot (or the sub-time slot) n, the terminal equipment feeds back HARQ-ACK corresponding to the PDSCH in the time slot (or the sub-time slot) n + k. The channel for feeding back the HARQ-ACK information in the n + k slot (or sub-slot) is referred to as the configured PUCCH.
If the HARQ-ACK is based on the time slot, the terminal equipment receives the PDSCH configured by the SPS in the time slot n, and the terminal equipment feeds back the HARQ-ACK corresponding to the PDSCH in the time slot n + k. The value of k is determined by a "PDSCH-to-HARQ-timing-indicator" field in the PDCCH, or by a higher layer signaling "dl-DataToUL-ACK". This field indicates that the value of k is one of a plurality of values configured for "dl-DataToUL-ACK" if the value of k is determined by "PDSCH-to-HARQ-timing-indicator" in the PDCCH.
If the HARQ-ACK is based on the sub-slot, the terminal equipment receives the last symbol of the PDSCH configured by the SPS and is positioned in the sub-slot n, and the terminal equipment feeds back the HARQ-ACK corresponding to the PDSCH in the sub-slot n + k. The value of k is determined by a "PDSCH-to-HARQ-timing-indicator" field in the PDCCH, or by a higher layer signaling "dl-DataToUL-ACK". This field indicates that the value of k is one of a plurality of values configured for "dl-DataToUL-ACK" if the value of k is determined by "PDSCH-to-HARQ-timing-indicator" in the PDCCH.
When a plurality of SPS configurations are used, the indicated k value is respectively scheduled for each SPS, and the activation time of each SPS configuration is different, which may cause the configured PUCCHs scheduled by the plurality of SPS configurations to collide in certain time.
As shown in fig. 1, it is assumed that the 2 SPS configurations are DL SPS configuration 1 and DL SPS configuration 2, respectively. The periodicity of DL SPS configuration 1 is 5 slots long, and the periodicity of DL SPS configuration 2 is 2 slots long. Within the illustrated target time, the terminal device needs to feed back HARQ-ACK for DL SPS configuration 1 and HARQ-ACK for DL SPS configuration 2. In other times, the terminal device only needs to feed back HARQ-ACK of DL SPS configuration 1 or HARQ-ACK of DL SPS configuration 2 at most.
FIG. 2 is a flow chart of an embodiment of the method of the present invention.
The embodiment of the application provides a semi-persistent scheduling hybrid automatic repeat request response method, which comprises the following steps:
101, a downlink control signaling contains an indication for activating N semi-static scheduling configurations, wherein N is an integer and is more than or equal to 2;
m HARQ-ACK feedback types in the N semi-static scheduling configurations are NACK-only, N-M HARQ-ACK feedback types are ACK/NACK, and M is larger than or equal to 1 and smaller than or equal to N.
Further, the method of the present application comprises:
102, feeding back on an actual PUCCH if P HARQ-ACK semi-static scheduling configurations of the M semi-static scheduling configurations have feedback time conflicts;
the configuration PUCCHs occupied by the responses of P HARQ-ACK semi-static scheduling configurations in the M semi-static scheduling configurations are overlapped on target time, wherein P is more than or equal to 1 and is less than or equal to M;
if P is 1, that is, only 1 NACK-only type feedback exists at the target time, the response information of the P semi-persistent scheduling configurations is fed back according to the NACK-only type on the corresponding configuration PUCCH;
that is, only HARQ-ACKs corresponding to 1 SPS PDSCH of the M SPS PDSCHs need to be fed back within the target time.
And if only HARQ-ACK corresponding to 1 SPS PDSCH in the M SPS PDSCHs needs to be fed back in the target time, the SPS configuration information comprises PUCCH resource configuration used for feeding back NACK-only HARQ-ACK information. If the terminal equipment correctly receives the SPS PDSCH, the terminal equipment does not feed back HARQ-ACK information of the SPS PDSCH; and if the terminal equipment does not correctly receive the SPS PDSCH, the terminal equipment determines PUCCH resources according to the PUCCH resource configuration and feeds back NACK information of the SPS PDSCH.
If P is greater than 1, namely, P is greater than or equal to 2 and less than or equal to M, response information of the P semi-static scheduling configurations is on an actual PUCCH at a target time, the actual PUCCH is one of P configured PUCCHs or one of standby PUCCHs in a preset standby PUCCH group, and the standby PUCCH group comprises at least one standby PUCCH.
And the HARQ-ACK corresponding to P (P >1) SPS PDSCHs in the M SPS PDSCHs needs to be fed back in the target time. As shown in fig. 1, let P be 2. The M SPS configurations are DL SPS configuration 1 and DL SPS configuration 2, respectively. The periodicity of DL SPS configuration 1 is 5 slots long, and the periodicity of DL SPS configuration 2 is 2 slots long. Within the illustrated target time, the terminal device needs to feed back HARQ-ACK for DL SPS configuration 1 and HARQ-ACK for DL SPS configuration 2. In other times, the terminal device only needs to feed back HARQ-ACK of DL SPS configuration 1 or HARQ-ACK of DL SPS configuration 2 at most.
In other times, the terminal device feeds back HARQ-ACK information according to the case where P is 1. In the target time, if the HARQ-ACK information of the DL SPS configuration 1 and the HARQ-ACK information of the DL SPS configuration 2 are both NACK, according to the case that the HARQ-ACK information feedback configuration types of the DL SPS configuration 1 and the DL SPS configuration 2 are NACK-only type, the terminal device may simultaneously feed back PUCCH resources for feeding back NACK-only HARQ-ACK information in the DL SPS configuration 1 configuration information and PUCCH resources for feeding back NACK-only HARQ-ACK information in the DL SPS configuration 2 configuration information. However, considering that the terminal device needs a specific processing capacity to transmit two uplink channels simultaneously and considering the transmission power efficiency of the terminal device, in many cases, the terminal device cannot transmit NACK information on the above two PUCCH resources simultaneously.
Steps 102A-B are described below as two sets of examples.
Step 102A, the actual PUCCH is one of standby PUCCHs in a preset standby PUCCH group; and the response information configured by the P semi-static scheduling is cascaded into an HARQ-ACK codebook on the actual PUCCH according to an ACK/NACK feedback type, and the response information configured by each semi-static scheduling occupies an independent HARQ-ACK information bit.
And sending HARQ-ACK information corresponding to the P SPS configurations in an actual PUCCH in a target time, wherein the actual feedback type of the HARQ-ACK information is an ACK/NACK type. That is, if the HARQ-ACK information feedback configuration type corresponding to the M SPS is NACK-only type. But where the P (at least 2) SPS corresponding HARQ-ACK feedbacks overlap at the target time, the HARQ-ACK feedbacks for the P SPS at the target time are automatically switched to ACK/NACK type.
For example, if at least one of the acknowledgement information of the P semi-persistent scheduling configurations is NACK, the acknowledgement information of the P semi-persistent scheduling configurations is concatenated into an HARQ-ACK codebook on the actual PUCCH according to an ACK/NACK feedback type, and the acknowledgement information of each semi-persistent scheduling configuration occupies an independent HARQ-ACK information bit. And the receiving end of the HARQ-ACK codebook determines the response result of each semi-static scheduling configuration according to the received ACK/NACK state of each information bit of the HARQ-ACK codebook.
For another example, in order to save overhead, if the acknowledgement information of the P semi-persistent scheduling configurations is ACK, the acknowledgement information of the P semi-persistent scheduling configurations is not sent. And the receiving end of the HARQ-ACK codebook determines the response result of each semi-static scheduling configuration according to the received ACK/NACK state of each information bit of the HARQ-ACK codebook, or judges that the response information of the P semi-static scheduling configurations is ACK according to the non-detection HARQ-ACK response result.
Further, the standby PUCCH group includes L standby PUCCHs for carrying HARQ-ACK information of two or more semi-persistent scheduling configurations; the length of the nth standby PUCCH used for carrying the response information is [ T ]n～Tn+1) A bit, where n ═ 1, 2, …, L; t isn≥2；Tn+1>Tn。
Preferably, the actual PUCCH is the jth spare PUCCH, T, in the spare PUCCH groupJ≤BP<TJ+1In which B isPIs the bit number of the response information of the P semi-persistent scheduling configurations.
For example, the standby PUCCH group includes at least two PUCCH resources, and the actual PUCCH belongs to the standby PUCCH group. And each PUCCH resource of the standby PUCCH group is applicable to different bit intervals, and the terminal equipment determines the actual PUCCH in the standby PUCCH group according to the HARQ-ACK information quantity of the P SPS configuration in the target time.
Under special conditions, the standby PUCCH groups are only 1 standby PUCCH, the terminal equipment acquires the configuration information of the actual PUCCH, and the actual PUCCH is used for the terminal equipment to feed back 2 or more than 2 HARQ-ACK information configured by SPS.
The terminal equipment acquires configuration information in advance, wherein the configuration information is used for configuring an actual PUCCH resource for the terminal equipment, and the actual PUCCH resource is specially used for feeding back 2 or more than 2 SPS configured HARQ-ACK information by the terminal equipment. And the terminal equipment feeds back the HARQ-ACK information configured by the P SPS on an actual PUCCH of the target time according to the resource configuration, wherein the type of the HARQ-ACK feedback is ACK/NACK type. Besides, the network device and the terminal device preset the ordering of the HARQ-ACK information of the P SPS configurations in the actual PUCCH.
The terminal device in the above step 102AConfiguration information is obtained in advance, the configuration information is used for configuring an actual PUCCH resource for the terminal equipment, and the actual PUCCH resource is specially used for the terminal equipment to feed back 2 or more than 2 SPS configured HARQ-ACK information. Because the value range of P may be relatively large, the network device only configures the terminal device with the format and resource amount of one PUCCH, which is too inefficient for feeding back the HARQ-ACK information of P SPS configurations in the target time. Therefore, another implementation form is that the network device configures a standby PUCCH group for the terminal device. The standby PUCCH group includes at least two PUCCH resources. Each PUCCH resource of the standby PUCCH group is applicable to a different bit interval. For example, the spare PUCCH group includes L PUCCH resources. Wherein the bit interval used by the nth (1 ≦ n ≦ L) PUCCH resource is [ T ≦ L ≦ n ≦ L%n～Tn+1). In this embodiment, the actual PUCCH in the target time transmits HARQ-ACK information corresponding to each of the P SPS configurations, where the actual feedback type of the HARQ-ACK information is an ACK/NACK type, and according to the bit number of the HARQ-ACK information, the terminal device may include, in the standby PUCCH, PUCCH resources in a bit interval having the bit number as the actual PUCCH resources.
Step 102B, the actual PUCCH is one of P configured PUCCHs, that is, the actual PUCCH is a k-th configured PUCCH in semi-persistent scheduling configuration, where k is 1, 2, …, P;
bundling the response information of the P semi-static scheduling configurations on the actual PUCCH according to the NACK-only feedback type;
the bundling according to the NACK-only feedback type means that NACK information is fed back if at least one of the acknowledgement information of the P semi-persistent scheduling configurations is NACK, otherwise HARQ-ACK is not fed back.
That is, if HARQ-ACK information of at least one of the P SPS configurations is NACK, transmitting NACK on an actual PUCCH at a target time; and if the HARQ-ACK information of the P SPS configurations is ACK, not sending the HARQ-ACK information of the P SPS configurations at the target time.
And if the HARQ-ACK information feedback configuration types corresponding to the M SPS are NACK-only types. Wherein P (P >1) SPS corresponding HARQ-ACK feedbacks overlap at a target time. And if the HARQ-ACK information of the P SPS configurations is ACK, not sending the HARQ-ACK information of the P SPS configurations at the target time. And if the HARQ-ACK information of at least one of the P SPS configurations is NACK, transmitting the NACK on an actual PUCCH of a target time. After the network device detects NACK feedback of the terminal device on an actual PUCCH, it considers that P SPS configurations all correspond to NACK feedback at the target time. Optionally, retransmission is scheduled for all the PDSCHs configured by the P SPS corresponding to the target time. The actual PUCCH is a PUCCH resource corresponding to the kth in the P SPS configurations, and the following implementation schemes are available for the actual PUCCH:
the value of k is preset. The network device and the terminal device may preset a value of K, and determine an actual PUCCH resource in PUCCH resources configured in each of the P SPS configurations, to send NACK information.
Or, the configuration index value of the kth semi-persistent scheduling configuration is the smallest of the P semi-persistent scheduling configuration index values.
Or, the configuration index value of the kth semi-persistent scheduling configuration is the largest of the P semi-persistent scheduling configuration index values.
If the terminal device supports being configured with two or two SPS configurations, each SPS configuration information comprises the configuration index of the SPS. And if the HARQ-ACK information of at least one of the P SPS configurations is NACK, transmitting the NACK on an actual PUCCH of a target time. The network device side also needs to know in advance which PUCCH resource the terminal device sends the NACK information, so as to avoid blind detection, and obtain the NACK information. In this implementation, the terminal device feeds back NACK on the PUCCH resource in the SPS configuration with the largest configuration index corresponding to each of the P SPS configurations, or, optionally, the terminal device may also feed back NACK on the PUCCH resource in the SPS configuration with the smallest configuration index corresponding to each of the P SPS configurations. The network equipment can detect NACK information in the determined PUCCH resources, the network equipment is prevented from acquiring the information that the PDSCH transmission corresponding to the SPS configuration is received by mistake, and the service quality is ensured.

Fig. 3 is a flowchart of an embodiment of the method of the present invention applied to a terminal device.
The method in any embodiment of the present application, applied to a terminal device, includes the following steps:
and the network equipment configures SPS resources for the terminal equipment through RRC signaling. After receiving the SPS configuration, the terminal equipment activates the SPS configuration through the PDCCH and receives data in corresponding resources according to the SPS period.
The SPS configuration includes parameters such as the number of processes in the period T, HARQ, PUCCH resources, and MCS table used. In this embodiment, the terminal device acquires a PDCCH for activating a semi-persistent scheduling configuration. Optionally, the PDCCH is scrambled with CS-RNTI.
The network equipment sends downlink service data through a PDSCH configured by SPS, and after receiving the service data, the terminal equipment feeds back ACK (acknowledgement) or NACK (non-acknowledgement) information received by the terminal equipment for the downlink service data on a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH). The ACK and NACK information are collectively referred to as hybrid automatic repeat request acknowledgement information HARQ-ACK. There are two feedback types for HARQ-ACK: one is of ACK/NACK type, i.e., ACK information is fed back for correctly received PDSCH and NACK information is fed back for erroneously received PDSCH; the other is a NACK-only type, i.e., HARQ-ACK information is not fed back for a correctly received PDSCH, and NACK information is fed back for an erroneously received PDSCH.
Considering that N SPS configurations may be for different services of the TSN network, for example, there are URLLC services with high requirements on delay sensitivity and reliability, and there are services for the conventional eMBB. Aiming at the URLLC service, the service reliability is high, and by adopting a NACK-only type HARQ-ACK feedback mode, the uplink signaling burden can be effectively reduced, and the transmission power efficiency of the terminal equipment can be improved. Aiming at the eMBB service, an ACK/NACK type HARQ-ACK feedback mode is adopted, the HARQ-ACK detection performance at a network equipment end is higher, the timely and effective retransmission of service data can be ensured, and the reliability of service is ensured. Therefore, in this embodiment, optionally, the network device may indicate mutually independent configuration information for the N SPS configurations, so as to configure an independent HARQ-ACK feedback manner for each SPS. Wherein the HARQ-ACK feedback manner refers to one of an ACK/NACK type and a NACK-only type. In this embodiment, M corresponding HARQ-ACK information feedback types in the N SPS configurations are NACK-only types. Wherein M is less than or equal to N.
Further, the method also comprises the following steps:
the terminal equipment acquires activation information of N SPS configurations, wherein M corresponding HARQ-ACK information feedback configuration types in the N SPS configurations are NACK-only types, and the other N-M corresponding HARQ-ACK information feedback configuration types are ACK/NACK types.
After the activation, the network equipment transmits the PDSCHs of the SPS according to the N SPS configuration periods, and the terminal equipment determines the HARQ-ACK feedback time of each SPS PDSCH according to the instruction of activating the PDCCH of each SPS configuration. According to the feedback configuration type of the fed-back HARQ-ACK information, the period of each SPS configuration and the time sequence relation between each SPS PDSCH and the fed-back HARQ-ACK, the HARQ-ACK information and the type to be fed back in the target time comprise the following situations:
in case one, only HARQ-ACK corresponding to 1 SPS PDSCH of the M SPS PDSCHs needs to be fed back within the target time;
under the second situation, HARQ-ACK corresponding to P (P >1) SPS PDSCHs in the M SPS PDSCHs only needs to be fed back in the target time;
and in case three, the HARQ-ACK and other basic HARQ-ACK information corresponding to P (P is more than or equal to 1) SPS PDSCHs in the M SPS PDSCHs only need to be fed back in the target time. The basic HARQ-ACK information refers to that the HARQ-ACK information feedback configuration type is ACK/NACK type, for example, HARQ-ACK information corresponding to N-M SPS configurations except for the HARQ-ACK information feedback configuration configured as NACK-only type among the N SPS configurations, HARQ-ACK information corresponding to dynamically scheduled PDSCH, and the like.
the actual PUCCH is one of the P configured PUCCHs or one of standby PUCCHs in a preset standby PUCCH group, and the standby PUCCH group comprises at least one standby PUCCH.
Wherein the actual PUCCH is one of standby PUCCHs in a preset standby PUCCH group; the standby PUCCH group comprises at least 1 (L-1) standby PUCCHs for carrying HARQ-ACK information of two or more semi-persistent scheduling configurations; when the standby PUCCH group comprises more than 2 (L is more than or equal to 2) standby PUCCHs, the length of the nth standby PUCCH for bearing the response information is [ T ]n～Tn+1) A bit, where n ═ 1, 2, …, L; t isn≥2；Tn+1>Tn. The actual PUCCH is the J-th spare PUCCH, T in the spare PUCCH groupJ≤BP<TJ+1In which B isPIs the bit number of the response information of the P semi-persistent scheduling configurations.
Wherein the actual PUCCH is one of P configured PUCCHs, that is, the actual PUCCH is a k-th configured PUCCH of semi-persistent scheduling configuration, where k is 1, 2, …, P; then, it is further preferred that the value of k is preset. Or, the configuration index value of the kth semi-persistent scheduling configuration is the smallest of the P semi-persistent scheduling configuration index values. Or, the configuration index value of the kth semi-persistent scheduling configuration is the largest of the P semi-persistent scheduling configuration index values.
