Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present application is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in this embodiment. The network-side device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), or a location server (e.g., an E-SMLC or an lmf (location Manager function)), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present application, only the base station in the NR system is taken as an example, but the embodiment of the present application does not limit the specific type of the base station and the specific communication system.

Future mobile communication systems need to adapt to more diverse scenarios and service requirements. The main scenes comprise mass machine Type Communication (mtc), Ultra Reliable Low Latency Communication (URLLC), and enhanced mobile broadband (eMBB), and the scenes provide requirements on the system such as high reliability, Low Latency, large bandwidth, wide coverage, and the like.

Different services have different Quality of Service (QoS) requirements, for example, URLLC supports low-delay, high-reliability services; the eMBB service supports the requirement of high throughput, but is less sensitive to latency and reliability than URLLC; in addition, for some UEs which may support services with different numerical configurations (numerology), the UE supports both URLLC low-latency high-reliability services and high-capacity high-rate eMBB services.

For a service which occurs periodically and has a fixed data packet size, in order to reduce the overhead of downlink control signaling, the network may continuously allocate a certain resource for the transmission of the periodic service in a semi-static scheduling manner. The DL SPS (semi-persistent scheduling) mode can reduce the overhead (mainly the overhead of a Physical Downlink Control Channel (PDCCH)) of scheduling a Voice packet of a Voice over Long-Term Evolution (VoLTE) Voice bearer, which is periodically transmitted and is small, so that more resources can be used for scheduling additional UEs.

The network configures parameters required by the DL SPS for the UE through high-level signaling, such as a period, a Hybrid Automatic Repeat reQuest (HARQ) process number, HARQ-ACK feedback resources, and the like. After the UE configures the DL SPS configuration, the base station activates the configured DL SPS configuration through Downlink Control Information (DCI). The DCI includes transmission parameters such as DL SPS transmission resources and Modulation and Coding Scheme (MCS). The UE determines the time instant of the DL SPS transmission and the frequency resources at the corresponding time instant by receiving the activation DCI. At each DL SPS time, the UE will listen for a corresponding data transmission on the DL SPS resources.

If the network is to release the allocated DL SPS resources, the base station may send a deactivation DCI to release the DL SPS resources.

In addition, the network may configure the UE with one or more DL SPS configuration resources to reduce latency, with a minimum SPS period of 1 slot.

HARQ-ACK timing is defined as an interval from a downlink data reception end time to a time of corresponding Acknowledgement (ACK) or/Negative Acknowledgement (NACK) feedback. NR supports flexible HARQ-ACK timing configuration for adapting to different services and network deployments. Each UE may configure a UE-specific HARQ-ACK timing table through Radio Resource Control (RRC), where the table includes multiple HARQ-ACK timing values, i.e., k1 values, and k1 is slot (slot) units. When the base station dynamically schedules downlink data transmission, a value of k1 is indicated in the DCI in an indexed manner, where the value of k1 is a value in a UE-specific HARQ-ACK timing table, and is used to notify the UE of the time when the UE feeds back HARQ-ACK.

For a DL SPS Physical Downlink Shared Channel (PDSCH) transmitted in slot n, its corresponding HARQ-ACK is transmitted on slot n + K, where K is indicated in the DCI activating the DL SPS.

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

In the related art, two types of HARQ-ACK codebook, type-1 are supported: semi-static HARQ-ACK codebook and type-2: dynamic (dynamic) HARQ-ACK codebook. For semi-static HARQ-ACK codebook, the UE determines HARQ-ACK codebook for all PDSCHs that may be fed back in a certain time slot according to parameters such as detection opportunity (PDCCH monitoring access) of PDCCH configured by RRC, time domain resource allocation (PDSCH-time domain resource allocation) of PDSCH, feedback timing (dl-DataToUL-ACK or PDSCH-toHARQ-timing) of PDSCH to HARQ-ACK, and so on. For dynamic HARQ-ACK codebook, UE determines HARQ-ACK codebook according to PDSCH actually scheduled, and because HARQ-ACK feedback is only carried out on PDSCH actually scheduled, the size of the codebook of HARQ-ACK is usually smaller than that of semi-static HARQ-ACK codebook. Which type of codebook the UE specifically uses is determined by RRC configuration.

In the related art, the base station may configure one or more (at most 4) PUCCH resource sets (PUCCH resource sets) for each UE through RRC signaling, and the RRC configures or predefines a maximum bit number of an Uplink Control Information (UCI) payload (payload) that each resource set (RESET) can carry (e.g., a first RESET is at most 2 bits, a2 rd RESET is N1, N2, a 4 th RESET is at most 1706 bits, N1, and N2 is an RRC configuration), and each RESET may include multiple PUCCH resources (at most 32 PUCCH resources in the first RESET, and other RESETs each include at most 8 PUCCH resources). On the UE side, the UE needs to feed back HARQ-ACK after receiving the PDSCH, in order to determine the PUCCH resource where the HARQ-ACK is fed back, the UE needs to determine a slot (slot) where the PUCCH is located through K1 in the PDCCH for scheduling the PDSCH, then determine a RESET where the PUCCH is located through the number of bits of the HARQ-ACK that needs to be fed back, and determine which PUCCH resource in the RESET is specifically determined according to a PUCCH resource indicator (PUCCH resource indicator, PRI) field (when resources included in the RESET are not more than 8) or a first Control Channel Element (CCE) index (first CCE index) of a PRI + PDCCH (when resources included in the RESET exceed 8). When there is HARQ-ACK feedback of multiple PDSCHs in one slot, UE determines PUCCH resources according to PRI and minimum CCE index in the last DCI (last DCI) for scheduling the PDSCHs.

In order to implement flexible network deployment, in an NR system, a transmission direction of each symbol in one slot is configured in a slot format (slot format).

The transmission direction of the timeslot in NR has three definitions, Downlink (DL), Uplink (UL), and flexible. When the network configures a timeslot or a symbol to be DL or UL, the transmission direction at that time is clear; when the network configures a slot or a symbol to be flexible, the transmission direction at that time is pending. The network may modify the transmission direction of the slot or symbol of the flexible by dynamic signaling, such as a dynamic Slot Format Indicator (SFI).

As shown in fig. 2, one slot may contain downlink (downlink), uplink (uplink) and flexible (flexible) Orthogonal Frequency Division Multiplexing (OFDM) symbols; the Flexible symbol may be rewritten as a downlink or uplink symbol.

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

The sfi (slot format indicator) may indicate the format of one or more slots. The SFI is transmitted in a Group Common (GC) -PDCCH. The SFI can flexibly change the slot format according to the requirement so as to meet the service transmission requirement. And the UE decides whether to monitor the PDCCH or not according to the indication of the SFI.

The base station may semi-statically configure the UE with one or more cell-specific slot formats via a higher layer parameter tdd-UL-DL-configuration common. The base station may also semi-statically UE configure one or more UE-specific slot formats with a higher layer parameter tdd-UL-DL-configuration determined. 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 direction implicitly indicated by the UE-specific RRC configuration is collectively referred to as measurement (measurement), including:

the method comprises the following steps of measuring a periodic or semi-continuous channel state information-reference signal (CSI-RS) configured by RRC signaling dedicated to UE, reporting the periodic CSI, and implicitly indicating an uplink transmission direction and a downlink transmission direction by the periodic or semi-continuous SRS;

a Physical Random Access Channel (PRACH) resource configured by RRC dedicated to the UE, type1 and type2 are unlicensed for uplink transmission;

for the unlicensed uplink transmission of type2, only the transmission on the first activated resource is regarded as UE-specific data (UE-specific data), and the UE-specific transmission includes a/N feedback of PDSCH, PUSCH, PDSCH, and aperiodic measurement triggered by DCI.

In the related mechanism, the HARQ-ACK feedback time of each SPS configuration is indicated by the respective active DCI, so that HARQ-ACKs corresponding to SPS PDSCHs of different SPS configurations may be fed back at different times. If the HARQ-ACK feedback time corresponding to one SPS PDSCH collides with DL, the HARQ-ACK of the SPS PDSCH will be discarded, thereby causing performance degradation of the SPS PDSCH.

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

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

step 101: the terminal receives semi-persistent scheduling (SPS) configuration parameters, wherein the SPS configuration parameters comprise at least one of the following items:

The SPS downlink resource is an OFDM symbol occupied by the SPS PDSCH in one slot, and a frequency domain resource, which may be indicated by an active DCI.

In the embodiment of the application, the network side equipment sends the SPS configuration parameters to the terminal, the SPS configuration parameters comprise a delay parameter i, a k1 value corresponding to each cluster of SPS downlink resources, a reference time window and the like, the transmission of HARQ-ACK corresponding to the SPS PDSCH can be ensured when the UE configures the SPS transmission, and the performance of DL SPS PDSCH transmission is improved.

The SPS downlink resource reception is to receive the SPS downlink resource, that is, to receive the SPS downlink resource.

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

and if the first time slot is an unavailable time slot, performing HARQ-ACK feedback on the ith uplink time slot after the first time slot.

In some embodiments, the delay parameter i is effective after the terminal receives the DCI for activating the downlink control information of the SPS configuration parameter.

In some embodiments, the SPS downlink resources configured by the SPS include a first resource and a second resource, a timeslot n1 of the first resource is earlier than a resource n2 of the second timeslot, a delay parameter i corresponding to the first resource is i1, and a delay parameter i corresponding to the second resource is i2, so that a kth 1+ i1 timeslot after the timeslot n1 is earlier than or equal to a kth 1+ i2 timeslot after the timeslot n 2.

In this embodiment, for one SPS configuration, a delay parameter i may be configured per slot, and if a slot determined by HARQ-ACK transmission of a PDSCH of one SPS according to a k1 value indicated by the network is an unavailable slot, the UE determines a UL slot for transmitting HARQ-ACK according to the delay parameter i, where the delay parameter i represents an ith available UL slot after a SPS PDSCH is received through k1 slots.

Of course, k1 may also be a sub-slot granularity.

In a specific embodiment, as shown in fig. 5, when HARQ-ACK feedback for one SPS PDSCH encounters an unavailable slot (e.g., PUCCH resources encounter DL or unavailable flexible symbols), the HARQ-ACK feedback for that SPS PDSCH will be delayed for transmission, and the delay parameter i may be characterized as delaying the transmission to the ith available UL slot. Through the operation, the HARQ-ACK of some SPS PDSCHs can be delayed to the first UL slot available after the time slot corresponding to k1, the HARQ-ACK of some SPS PDSCHs can be delayed to the second UL slot available after the time slot corresponding to k1, the HARQ-ACK of some SPS PDSCHs can be delayed to the nth UL slot available after the time slot corresponding to k1, and n is an integer larger than 2, so that load balancing is achieved.

Further, the delay parameter i may be configured or indicated at time tp, e.g.,

t _ P is N cycle, N > is 1. In one specific example, T _ P ═ M (sub-) slot, M > ═ 1.

T _ P may be related to SCS, i.e. different SCS, T _ P may not take the same value.

For any two SPS PDSCHs configured by one SPS, if the slot of the kth SPS PDSCH occurs earlier than the slot of the mth SPS PDSCH, the network side needs to ensure that the HARQ-ACK of the kth SPS is not later than the HARQ-ACK of the mth SPS, and the slot can be the same slot or the previous slot, so that the occurrence of out-of-order execution (out-of-order) is avoided.

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

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

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

In a specific embodiment, as shown in fig. 6, for 7 SPS PDSCHs in one SPS configuration, the network side indicates respective k1 values, and in this embodiment, the network side indicates 2 different k1 values: k1_1, k1_ 2.

Thus, the HARQ-ACKs for the PDSCH of different SPS are grouped according to the indicated value of k 1. The first cluster is the PDSCH for the SPS at slot0-3, and the second cluster is the PDSCH for the SPS at slot 4-6.

Further, the network side may configure a period, cluster division in the period, and a corresponding k1 set, and indicate a certain k1 set by the activation or reactivation DCI, and then k1 in the k1 set is sequentially applied to each cluster.

For example, the network side configuration period is 10ms, cluster 1 includes slots 0-3, and cluster 2 includes slots 4-6.

The corresponding set of k1 is

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

Two values of k1 set, k1 set in the activation or reactivation DCI indication table apply to cluster 1 and cluster 2, respectively.

The network side may configure the value of k1 used by the HARQ-ACK of PDSCH of one SPS within a cluster to be the value of k1 indicating the HARQ-ACK of the first or last or middle SPS PDSCH within the cluster. For example: the network side configures the value of k1 of the HARQ-ACK of the last SPS PDSCH in one cluster as a valid value of k1, and the first cluster is configured according to the HARQ-ACK of the last SPS PDSCH in the cluster: k1 ═ 5; second cluster, HARQ-ACK per last SPS PDSCH of cluster: k1 ═ 2.

In addition, the network side needs to ensure that when different slot configurations are changed, the indicated value of k1 should be a valid value of k 1.

In some embodiments, the SPS configuration parameters further include:

and the first indication information is used for indicating that if the first time slot is the unavailable time slot, the feedback of SPS downlink resource receiving is carried out to the first available time slot after delaying.

In some embodiments, the first slot is an unavailable slot if the first slot comprises at least partially unavailable flexible symbols and conflicts with PUCCH resources carrying HARQ-ACK feedback; or

And if the first time slot comprises at least part of downlink symbols and conflicts with PUCCH resources bearing HARQ-ACK feedback, the first time slot is an unavailable time slot.

In this embodiment, for one SPS configuration, the slot determined by the HARQ-ACK transmission of the PDSCH of the SPS according to the k1 value indicated by the network side is an unavailable slot, and the UE transmits the delayed HARQ-ACK to the available slot. When a deferred slot encounters a slot that contains all or part of the flexible symbols, one way is: whether the slot is configured by higher layer signaling is an available slot, such as configuring a set or a subset of an available resource (e.g., a UL slot or a self-contained slot of an existing UL, DL and flexible symbol) by RRC, where all slots in the set are valid resources, i.e., available slots, and may be used for feeding back HARQ-ACK; the other mode is as follows: slots determined according to the indicated k1 value are all regarded as available 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 one slot, the flexible symbols in the slot corresponding to the k1 value indicated by the network indication (e.g., activation DCI) are valid resources, and the PUCCH may be transmitted.

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

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

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

and receiving third indication information of the network side device, where the third indication information is used to indicate whether the first available timeslot is an effective resource capable of performing feedback, and the received SPS downlink resource may be fed back on the effective resource.

In some embodiments, the method further comprises:

receiving fourth indication information of the network side device, where the fourth indication information is used to indicate that the flexible symbol in the first time slot is an effective resource capable of performing feedback, and the received SPS downlink resource may be fed back on the effective resource.

In some embodiments, if the SPS configuration parameters include a reference time window, the method further comprises:

and determining the SPS downlink resources corresponding to each uplink time slot according to the number of the uplink time slots in the reference time window and the number of the SPS downlink resources, performing HARQ-ACK feedback on the SPS downlink resources in the corresponding uplink time slots, and allocating the number of the SPS downlink resources corresponding to different uplink time slots according to a predefined rule, wherein the difference of the number of the SPS downlink resources corresponding to different uplink time slots is not more than 1.

The number of SPS downlink resources may be the number of SPS downlink resources configured by the network side, or may be the number of effective SPS downlink resources. Both of these ways may be configured by the network side.

If the symbols of one slot collide with the symbols of the SPS downlink resources, these SPS downlink resources are not valid SPS downlink resources.

The SPS downlink resource is a valid SPS downlink resource if the DL symbol portion of the slot containing the flexible symbol can transmit SPS downlink resources. And for the quantity of the SPS downlink resources configured on the network side, performing HARQ-ACK feedback no matter whether the SPS downlink resources are effective SPS downlink resources, feeding back NACK for the SPS downlink resources which are not effective SPS downlink resources, and feeding back HARQ-ACK information for the SPS downlink resources which are effective.

In this embodiment, the network side configures a reference time window T, which includes a starting slot index and a length of the time window, and determines the UL slot of HARQ-ACK feedback of each SPS PDSCH according to the number of UL slots in T indicated by a network high-layer parameter (tdd-UL-DL-configuration common or tdd-UL-DL-configuration dedicated) and the number of configured SPS PDSCHs, so that the number of SPS PDSCHs corresponding to each UL slot is almost the same. The PUCCH resource indicated (DCI activated or network configured) by the SPS is used for feedback in the slot.

The network side configures a time window T, and may configure at least one of a starting radio frame, subframe, slot, offset (offset of radio frame, subframe, or slot) and a period L (period of radio frame, subframe, or slot), for example, for a 15kHz subcarrier spacing:

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

the other time window T is configured as a starting wireless frame 0, the offset is 1 subframe, and the period is 10 subframes;

another time window T is configured to start radio frame 0 with an offset of 1 slot and a period of 10 slots.

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

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

Thus, as shown in FIG. 7, the PUCCH of the U1 slot feeds back the HARQ-ACK bit of the first 4 SPS in the time window T1, and the PUCCH of the U2 slot feeds back the HARQ-ACK bit of the last 3 SPS. HARQ-ACK for the first 3 SPS of time window T2 is fed back at U3, and so on.

In this embodiment, the slot (slot F) containing the flexible symbol in T1, which is not a slot containing valid SPS downlink resources, is not capable of transmitting SPS PDSCH (possibly due to collision with SPS downlink resources). A slot (slot F) containing a flexible symbol in T2 may transmit the SPS PDSCH.

Further, within the reference time window T, the UL slot may also be counted if the UL symbol portion of the slot containing the flexible symbols is available for transmission of HARQ-ACKs for SPS. The SPS downlink resource is a valid SPS downlink resource if the DL symbol portion of the slot containing the flexible symbol can transmit SPS downlink resources.

Further, T ═ P (provided by pattern 1, and may be configured by tdd-UL-DL-configuration common), or T ═ P + P2 (provided by pattern 1 and pattern2, respectively, and may be configured by tdd-UL-DL-configuration common).

Alternatively, the network side may determine the clusters according to the number of switching points within the time T. As shown in fig. 8, there are three UL-DL switching points in total within time T, which are divided into 3 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 (number of SPS PDSCHs/number of available UL slots) or floor (number of SPS PDSCHs/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 may differ by 1 at most. Similarly, if the UL symbol portion of a slot containing flexible symbols may be used for transmission of HARQ-ACKs for SPS, the UL slot may also be counted.

It is noted that the above scheme may be applied to the case of multiple SPS configurations. The technical solution of this embodiment may be used in an LTE system, and may also be extended to an unlicensed frequency band, where a HARQ-ACK cannot be sent due to carrier sensing (Listen Before Talk, LBT), such as a Time Division Duplex (TDD) or Frequency Division Duplex (FDD) scenario of the unlicensed frequency band.
