Referring to FIG. 1 , FIG. 1 shows a block diagram of a wireless communication system to which the embodiments of the present application can be applied. The wireless communication system includes a terminal 11 and a network-side device 12 . The terminal 11 may also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), mobile Internet Device (Mobile Internet Device, MID), wearable device (Wearable Device) or vehicle-mounted device and other terminal-side devices, it should be noted that the embodiment of the present application does not limit the specific type of the terminal 11.

Future mobile communication systems need to adapt to more diverse scenarios and business needs. The main scenarios include Massive Machnice Type Communication (mMTC), UltraReliable Low Latency Communication (URLLC), and Enhanced Mobile Broadband (eMBB). These scenarios provide high reliability for the system. , low latency, large bandwidth, wide coverage and other requirements.

Different services have different Quality of Service (QoS) requirements. For example, URLLC supports low-latency and high-reliability services; eMBB services support high-throughput requirements, but are not as sensitive to latency and reliability as URLLC; In addition, for some UEs that may support services with different numerical configurations, the UE not only supports URLLC low-latency and high-reliability services, but also supports large-capacity and high-speed eMBB services.

For services that appear periodically and have a relatively fixed packet size, in order to reduce the overhead of downlink control signaling, the network can use semi-static scheduling to continuously allocate certain resources for the transmission of periodic services. This downlink semi-persistent scheduling (DL SPS) method can reduce the overhead of scheduling periodically sent and small Voice over Long-Term Evolution (VoLTE) voice packets (mainly physical downlink). control channel (Physical Downlink Control Channel, PDCCH) overhead), thereby making more resources available for scheduling additional UEs.

The network configures the UE through high-layer signaling with parameters required for DL SPS, such as period, number of Hybrid Automatic Repeat reQuest (HARQ) processes, and resources for HARQ-ACK feedback. After the UE is configured with the DL SPS configuration, the base station activates the configured DL SPS configuration through downlink control information (Downlink Control Information, DCI). The DCI will include DL SPS transmission resources and transmission parameters such as a modulation and coding scheme (Modulation and Coding Scheme, MCS). The UE determines the time of DL SPS transmission and the frequency resource at the corresponding time by receiving the activated DCI. At each DL SPS moment, the UE will monitor whether there is corresponding data transmission on the DL SPS resource.

If the network wants to release the allocated DL SPS resources, the base station can send the deactivated DCI to release the DL SPS resources.

In addition, the network can configure one or more DL SPS configuration resources for the UE to reduce the delay, and the minimum SPS period is 1 slot.

The HARQ-ACK timing is defined as the interval from the time when the downlink data is received to the time when the corresponding acknowledgement (ACK) or/or negative acknowledgement (NACK) is fed back. NR supports flexible HARQ-ACK timing configuration for different services and network deployments. Each UE can configure a UE-specific HARQ-ACK timing table through Radio Resource Control (RRC). ) as a unit. When dynamically scheduling downlink data transmission, the base station will indicate a value of k1 in the DCI in the form of an index, where k1 is a value in the UE-specific HARQ-ACK timing table, which is used to notify the UE of the timing of HARQ-ACK feedback.

For a DL SPS Physical Downlink Shared Channel (PDSCH) sent at slot n, its corresponding HARQ-ACK is transmitted at slot n+K, where K is the indication in the DCI that activates the DL SPS .

For the HARQ-ACK process supporting TB-level feedback, each transport block (TB) corresponds to feedback one HARQ-ACK bit. The UE needs the ability to indicate its minimum HARQ processing time (minimum HARQ processing time means the minimum time required from Downlink data reception to the corresponding HARQ-ACK transmission timing). Asynchronous and adaptive Downlink HARQ is supported for eMBB and URLLC. From the perspective of the UE, HARQ-ACK feedback of multiple PDSCHs can be transmitted in an uplink (Uplink, UL) data/control region in time, and a HARQ-ACK codebook is formed on this UL time resource. The timing between PDSCH reception and corresponding ACK/NACK is specified in DCI.

In the related art, two types of HARQ-ACK codebooks are supported, type-1: semi-static HARQ-ACK codebook and type-2: dynamic HARQ-ACK codebook. For the semi-static HARQ-ACK codebook, the UE configures the PDCCH detection opportunity according to RRC (PDCCH monitoring access), PDSCH time domain resource allocation (PDSCH-TimeDomainResourceAllocation), PDSCH to HARQ-ACK feedback timing (dl-DataToUL-ACK or Parameters such as PDSCH-toHARQ-timing) determine all PDSCHs that may be fed back in a certain time slot to determine the HARQ-ACK codebook. Since HARQ may include actually scheduled and unscheduled PDSCHs, the codebook will generally be larger. For the dynamic HARQ-ACK codebook, the UE determines the HARQ-ACK codebook according to the actually scheduled PDSCH. Since the HARQ-ACK feedback is only performed on the actually scheduled PDSCH, the size of the HARQ-ACK codebook is usually smaller than that of the semi-static HARQ-ACK. The codebook size of the codebook. Which type of codebook the UE uses is determined by the RRC configuration.

In the related art, the base station can configure one or more (up to 4) PUCCH resource sets (PUCCH resource sets) for each UE through RRC signaling, and RRC configures or predefines the uplink control that each resource set (RESET) can bear. The maximum number of bits of the payload (uplink control information, UCI) (for example, the first RESET is up to 2 bits, the second and third RESET are N1, N2, and the fourth RESET is up to 1706 bits, N1, N2 is an RRC configuration), each RESET can contain multiple PUCCH resources (up to 32 PUCCH resources in the first RESET, and up to 8 PUCCH resources in each of the other RESETs). On the UE side, the UE needs to feed back the HARQ-ACK after receiving the PDSCH. In order to determine the PUCCH resource where the HARQ-ACK is fed back, the UE needs to first determine the time slot (slot) where the PUCCH is located by scheduling K1 in the PDCCH of the PDSCH, and then pass the PUCCH that needs to be fed back. The number of bits of the HARQ-ACK determines the RESET where the PUCCH is located. Within the determined RESET, according to the PUCCH resource indicator (PUCCH resource indicator, PRI) field of the PDCCH (when the number of resources contained in the RESET does not exceed 8) or the PRI+PDCCH first The first CCE index (first CCE index) of each control channel element (CCE) determines which PUCCH resource in the RESET is specifically (when the RESET contains more than 8 resources). When HARQ-ACKs of multiple PDSCHs are fed back in one slot, the UE determines the PUCCH resource according to the PRI and the minimum CCE index in the last DCI (last DCI) that schedules these PDSCHs.

In order to realize flexible network deployment, in the NR system, the transmission direction of each symbol in a time slot is configured by means of a slot format.

There are three definitions of transmission directions of time slots in NR, downlink (DL), uplink (UL), and flexible. When the network configures a time slot or the symbol is DL or UL, the transmission direction at this moment is clear; when the network configures a time slot or the symbol is flexible, the transmission direction at this moment is to be determined. The network can modify the transmission direction of flexible time slots or symbols through dynamic signaling, such as a dynamic slot format indicator (SFI).

As shown in Figure 2, a slot can include downlink, uplink and flexible orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols; Flexible symbols can be rewritten as downlink or uplink symbol.

For the convenience of description, a slot containing all DL symbols is called a DL slot (ie, D in the figure). A slot containing all UL symbols is called a UL slot (ie, U in the figure). A slot including all flexible symbols or a slot including DL, UL and flexible symbols is called a special slot (ie, F in the figure).

SFI (slot format indicator) can indicate the format of one or more slots. SFI is sent in Group Common (GC)-PDCCH. SFI can flexibly change the slot format according to requirements to meet service transmission requirements. The UE decides whether to monitor the PDCCH according to the indication of the SFI.

The base station may semi-statically configure one or more cell-specific slot formats for the UE through the high layer parameter tdd-UL-DL-ConfigurationCommon. The base station may also semi-statically configure one or more UE-specific (UE-specific) slot formats for the UE through the high layer parameter tdd-UL-DL-ConfigurationDedicated. The base station can rewrite the flexible symbol or slot in the semi-static configuration through the SFI carried in the GC-PDCCH.

The transmission directions implicitly indicated by the UE-specific RRC configuration are collectively referred to as measurements, including:

Periodic or semi-persistent channel state information-reference signal (CSI-RS) measurement configured by UE-specific RRC signaling, periodic CSI reporting, and uplink and downlink transmission directions implicitly indicated by periodic or semi-persistent SRS;

UE-specific RRC configuration Physical Random Access Channel (PRACH) resources, type1 and type2 license-free uplink transmission;

For type 2 license-free uplink transmission, only the transmission on the first activated resource is regarded as UE-specific data, and UE-specific transmission includes PDSCH, PUSCH, PDSCH A/N feedback, and DCI triggering aperiodic measurements, etc.

In the related mechanism, the HARQ-ACK feedback time of each SPS configuration is indicated by the respective activated DCI, so the HARQ-ACK corresponding to the SPS PDSCH of different SPS configurations may be fed back at different times. However, if the HARQ-ACK feedback time corresponding to an SPS PDSCH collides with the DL, the HARQ-ACK of the SPS PDSCH will be discarded, thereby causing the performance of the SPS PDSCH to be degraded.

The HARQ-ACK of the SPS PDSCH can be deferred to subsequent uplink resources for transmission. However, this will cause multiple HARQ-ACKs to be transmitted on a certain uplink resource in a concentrated manner, resulting in a large uplink load and affecting the uplink performance.

An embodiment of the present application provides a semi-static scheduling configuration method, as shown in FIG. 3 , including:

Step 101: The terminal receives semi-persistent scheduling SPS configuration parameters, where the SPS configuration parameters include at least one of the following:

The delay parameter i of the time slot n where the SPS downlink resource is received is used to indicate the ith available uplink time slot after the first time slot, and the first time slot is the time slot n after k1 time slots. Time slot n+k1, i is a positive integer, k1 is a non-negative integer;

The k1 value corresponding to each cluster of SPS downlink resources, each cluster of SPS downlink resources includes at least one SPS downlink resource, and the time slot n+k1 after k1 time slots for receiving the SPS downlink resources of this cluster is for HARQ- Time slot for ACK feedback;

A reference time window, wherein the second uplink time slot where the HARQ-ACK feedback of each SPS downlink resource is received is determined according to the reference time window.

The SPS downlink resources are the OFDM symbols occupied by the SPS PDSCH in one slot, and the frequency domain resources, which may be indicated by the activated DCI.

In this embodiment of the present application, the network side device sends the SPS configuration parameters to the terminal, and the SPS configuration parameters include the delay parameter i, the k1 value corresponding to each cluster of SPS downlink resources, and the reference time window, etc., which can ensure that when the UE is configured with SPS transmission, Transmission of HARQ-ACK corresponding to SPS PDSCH improves the performance of DL SPS PDSCH transmission.

The receiving of the SPS downlink resources is to receive the SPS downlink resources, that is, to receive the SPS downlink resources.

In some embodiments, if the SPS configuration parameter includes a delay parameter i, the method further includes:

If the first time slot is an unavailable time slot, HARQ-ACK feedback is performed in the i-th uplink time slot after the first time slot.

In some embodiments, the delay parameter i takes effect after the terminal receives the activation downlink control information DCI of the SPS configuration parameter.

In some embodiments, the SPS downlink resources configured by the SPS include a first resource and a second resource, the time slot n1 of the first resource is earlier than the resource n2 of the second time slot, and the delay parameter i corresponding to the first resource is i. is i1, and the delay parameter i corresponding to the second resource is i2, then the k1+i1 th time slot after the time slot n1 is earlier than or equal to the k1+i2 th time slot after the time slot n2.

In this embodiment, for an SPS configuration, a delay parameter i can be configured for each slot. If the slot determined by the k1 value of the network instructed by the HARQ-ACK transmission of the PDSCH of an SPS is an unavailable time slot, then the UE will use the delay parameter according to the i determines the UL slot for transmitting HARQ-ACK, and the delay parameter i represents the i-th available UL slot after a SPS PDSCH is received after k1 slot.

Of course, k1 can also be sub-slot granularity.

In a specific embodiment, as shown in FIG. 5 , when the HARQ-ACK feedback of an SPS PDSCH encounters an unavailable time slot (for example, the PUCCH resource encounters DL or an unavailable flexible symbol), the HARQ-ACK feedback of the SPS PDSCH will be Delay transmission, the delay parameter i can be characterized as delaying the transmission to the ith available UL slot. After this operation, the HARQ-ACK of some SPS PDSCHs can be delayed to the first UL slot that can be used after the time slot corresponding to k1, and the HARQ-ACK of some SPS PDSCHs can be delayed to the time slot corresponding to k1. In the second UL slot of , some HARQ-ACKs of the SPS PDSCH are delayed to the nth UL slot available after the time slot corresponding to k1, where n is an integer greater than 2, so as to achieve load balance.

Further, the delay parameter i may be configured or indicated per time T_P, for example,

T_P=N*period, N>=1. In a specific example, T_P=M*(sub-)slot, M>=1.

T_P may be related to SCS, that is, different SCSs have different values of T_P.

For any two SPS PDSCHs configured by one SPS, if the slot of the k-th SPS PDSCH appears earlier than the slot of the m-th SPS PDSCH, the network side needs to ensure that the HARQ-ACK of the k-th SPS is not later than the m-th SPS's HARQ-ACK HARQ-ACK can be the same slot or the previous slot to avoid out-of-order execution.

In some embodiments, if the SPS configuration parameter includes the k1 value corresponding to each cluster of SPS downlink resources, the method further includes:

Receive second indication information, where the second indication information is used to indicate that the value of k1 corresponding to a cluster of SPS downlink resources is: the first SPS downlink resource or the last SPS downlink resource or the middle SPS downlink resource in the cluster of SPS downlink resources The corresponding k1 value.

In this embodiment, for an SPS configuration, the per slot configuration k1 value may be instructed by activating the DCI. The same k1 value is a cluster, and the network side configures which SPS PDSCH HARQ-ACK in a cluster corresponds to a valid k1 value.

In a specific embodiment, as shown in FIG. 6 , for 7 SPS PDSCHs in an SPS configuration, the network side indicates respective k1 values. In this embodiment, the network side indicates two different k1 values: k1_1 and k1_2.

In this way, HARQ-ACKs of PDSCHs of different SPSs are grouped according to the indicated k1 value. The first cluster is the PDSCH of the SPS in slots 0-3, and the second cluster is the PDSCH of the SPS in slots 4-6.

Further, the network side can configure the period, the cluster division in the period and the corresponding k1 set set, and a certain k1 set is indicated by the activation or reactivation of the DCI, and the k1 in this k1 set is applied to each cluster in turn.

For example, the configuration period on the network side is 10ms, cluster 1 includes slot0-slot3, and cluster 2 includes slot4-slot6.

The corresponding k1 set is

Codepoint k1 set 00 {k1_1, k1_2} 01 {k1_3, k1_4} 10 {k1_5, k1_6} 11 {k1_7, k1_8}

Activates or reactivates the k1 set in the DCI indication table, and the two values in the k1 set apply to cluster 1 and cluster 2, respectively.

The network side can configure the value of k1 used by the HARQ-ACK of the PDSCH of an SPS in a cluster to be the value of k1 that indicates the HARQ-ACK of the first or last or middle SPS PDSCH in the cluster. For example: the network side configures the k1 value of the HARQ-ACK of the last SPS PDSCH in a cluster to be a valid k1 value, the first cluster, according to the HARQ-ACK of the last SPS PDSCH of the cluster: k1=5; the second cluster , according to the HARQ-ACK of the last SPS PDSCH of the cluster: k1=2.

In addition, the network side needs to ensure that when changing the configuration of different time slots, the indicated k1 value should be a valid k1 value.

In some embodiments, the SPS configuration parameters further include:

The first indication information is used to indicate that if the first time slot is an unavailable time slot, the SPS downlink resource receiving feedback is delayed to the first available time slot.

In some embodiments, the first time slot is an unavailable time slot if the first time slot includes at least part of the unavailable flexible symbols and collides with the PUCCH resource carrying HARQ-ACK feedback; or

If the first time slot includes at least part of downlink symbols and collides with the PUCCH resource carrying HARQ-ACK feedback, the first time slot is an unavailable time slot.

In this embodiment, for an SPS configuration, the slot determined according to the k1 value indicated by the network side for HARQ-ACK transmission of the PDSCH of the SPS is an unavailable time slot, and the UE will delay the HARQ-ACK transmission to the available slot. When the delayed slot encounters a slot that contains all or some flexible symbols, one way is to configure whether the slot is an available time slot through high-layer signaling, such as configuring available resources (such as UL slot or both) through RRC. A set or subset of self-contained slots with UL, DL and flexible symbols), all slots in the set are valid resources, that is, available slots, which can be used to feed back HARQ-ACK; another way is: follow the instructions The slots determined by the k1 value of , are regarded as available time slots, and HARQ-ACK resources can be fed back. That is, if the PUCCH resource for feeding back HARQ-ACK overlaps with all or part of the flexible symbols in a slot, the flexible symbols in the slot corresponding to the k1 value indicated by the network instruction (such as activating DCI) are valid resources, and PUCCH can be transmitted .

In addition, if the SFI indicates that a slot containing all or part of the flexible symbols is available, the time slot can be used for HARQ-Ack feedback. If the UE does not receive the SFI, when encountering a slot containing all or part of the flexible symbols slot, the time slot is regarded as an unavailable resource, and the UE searches for the next available slot.

In a specific embodiment, when the format of a slot collides with the PUCCH resource of the HARQ-ACK of an SPS PDSCH, the slot may be called an unavailable time slot. For example, if the time domain length of the PUCCH resource of the HARQ-ACK of the SPS PDSCH is OFDM i~j within a slot, and if OFDM i~j has any DL symbol or an unavailable flexible symbol, the slot can be called an unavailable slot . If the UE does not receive SFI, when encountering a slot containing all or part of the flexible symbols, the slot is regarded as an available resource (for an unlicensed band). Not generally, if the UE does not receive the SFI, when encountering a slot containing all or part of the flexible symbols, the slot can be regarded as an unavailable resource. The two methods can be configured by the network or determined according to the frequency band characteristics, such as unlicensed frequency band or licensed frequency band.

In some embodiments, if the SPS configuration parameter includes the first indication information, and the first available time slot indicated by the first indication information includes at least part of flexible symbols, the method further includes:

Receive third indication information of the network-side device, where the third indication information is used to indicate whether the first available time slot is an effective resource that can perform feedback, and the received SPS downlink resource can be performed on the effective resource feedback of.

In some embodiments, the method further includes:

The fourth indication information of the network side device is received, which is used to indicate that the flexible symbol in the first time slot is an effective resource capable of feedback, and feedback of the received SPS downlink resource can be performed on the effective resource.

In some embodiments, if the SPS configuration parameter includes a reference time window, the method further includes:

The SPS downlink resource corresponding to each uplink time slot is determined according to the number of uplink time slots in the reference time window and the number of SPS downlink resources. The SPS downlink resource performs HARQ-ACK feedback in the corresponding uplink time slot. Define rules to allocate the number of SPS downlink resources corresponding to different uplink time slots, for example, the difference in the number of SPS downlink resources corresponding to different uplink time slots is not greater than 1.

The number of SPS downlink resources may be the number of SPS downlink resources configured on the network side, or may be the number of valid SPS downlink resources. These two ways can be configured by the network side.

If a symbol of a slot collides with a symbol of SPS downlink resources, these SPS downlink resources are not valid SPS downlink resources.

If the DL symbol part in the time slot containing flexible symbols can transmit SPS downlink resources, then the SPS downlink resources are valid SPS downlink resources. For the number of SPS downlink resources configured on the network side, HARQ-ACK feedback is performed regardless of whether the SPS downlink resources are valid SPS downlink resources. ACK information.

In this embodiment, the network side configures a reference time window T, including the start slot index and the length of the time window, according to the T The number of UL slots and the number of configured SPS PDSCHs determine the UL slot for the HARQ-ACK feedback of each SPS PDSCH, so that the number of SPS PDSCHs corresponding to each UL slot is almost the same. The PUCCH resource indicated by the network for the SPS (activated DCI or network configuration) is used for feedback in the slot.

The network side configures the time window T, which can configure the starting radio frame, subframe, slot, offset offset (radio frame, subframe, or slot offset offset) and period L (the period of the radio frame, subframe, or slot). ), e.g. for 15kHz subcarrier spacing:

A configuration of the time window T is the starting radio frame 0, the offset is 0, and the period is 1 radio frame;

Another configuration of the time window T is the starting radio frame 0, the offset is 1 subframe, and the period is 10 subframes;

Another configuration of the time window T is the starting radio frame 0, the offset is 1 slot, and the period is 10 slots.

In a specific embodiment, if within the time window T, for N valid SPS PDSCHs, the determined UL slots are Q, and the SPS PDSCHs are evenly divided into Q groups as much as possible, and the maximum difference between the number of SPS PDSCHs in each group is 1 , arranged in descending order (or reverse order) according to the quantity of each group of SPSPDSCHs.

For example: the network side configures an SPS configuration with a period of 1 slot, assuming that the time window T is 10ms long, for the first T1, the semi-static UL slot in this time window is 2, in order to determine the feedback HARQ-ACK UL slot, the UE will determine the HARQ-ACK feedback of the SPS PDSCH according to the number of configured SPS configurations and the number of UL slots.

In this way, as shown in Figure 7, the PUCCH of the U1 time slot feeds back the HARQ-ACK bits of the first 4 SPSs in the time window T1, and the PUCCH of the U2 time slot feeds back the HARQ-ACK bits of the last 3 SPSs. The HARQ-ACKs of the first 3 SPSs of the time window T2 are fed back at U3, and so on.

In this embodiment, the time slot (slot F) containing flexible symbols in T1 cannot transmit SPS PDSCH (possibly due to conflict with SPS downlink resources), and this F time slot is not a time slot containing valid SPS downlink resources. A slot (slot F) containing flexible symbols in T2 can transmit SPS PDSCH.

Further, within the reference time window T, if the UL symbol part in the slot containing flexible symbols can be used to transmit the HARQ-ACK of the SPS, it can also be counted in the UL slot. If the DL symbol part in the time slot containing flexible symbols can transmit SPS downlink resources, then the SPS downlink resources are valid SPS downlink resources.

Further, T=P (provided by pattern 1, configurable by tdd-UL-DL-ConfigurationCommon), or T=P+P2 (provided by pattern 1 and pattern2, respectively, configurable by tdd-UL-DL-ConfigurationCommon) .

Optionally, the network side may determine the cluster according to the number of switching points within the time T. As shown in FIG. 8 , there are three UL-DL switching points in time T, which are divided into three clusters.

The number of SPS PDSCHs fed back by one UL slot in each cluster is distributed as uniformly as possible, that is, the number of SPS PDSCHs fed back by each UL slot is ceil (the number of SPS PDSCHs/the number of available UL slots) or floor (the number of SPS PDSCHs) /The number of available UL slots), where ceil is rounded up and floor is rounded down, so that the number of SPS PDSCHs fed back by any UL slot can differ by at most 1. Similarly, if the UL symbol portion of a slot containing flexible symbols is available to transmit HARQ-ACK for SPS, it may also be counted in the UL slot.

It is worth noting that the above scheme can be applied to the case of multiple SPS configurations. The above technical solution in this embodiment can be used in an LTE system, and can also be extended to an unlicensed frequency band. The HARQ-ACK cannot be sent due to carrier sense (Listen Before Talk, LBT), such as the time-division dual-frequency unlicensed frequency band. duplex (TDD) or frequency division duplex (FDD) scenarios.
