[0044] See also Figure 1 , Figure 1A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. 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 terminal (User Equipment, UE). The terminal 11 may be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device.

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.

[0045] Future mobile communication systems need to adapt to more diverse scenarios and business requirements. The main scenarios include massive machine type communication (mMTC), ultra-reliable low latency communication (URLLC), and enhanced mobile broadband (eMBB). These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage.

[0046] Different services have different Quality of Service (QoS) requirements. For example, URLLC supports low-latency, high-reliability services. eMBB services support high throughput requirements, but are not as sensitive to latency and reliability as URLLC. In addition, some UEs may support services with different numerologies. UEs support both URLLC low-latency and high-reliability services and large-capacity and high-rate eMBB services.

[0047] For services that appear periodically and have a relatively fixed data packet size, in order to reduce the overhead of downlink control signaling, the network can use semi-persistent 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 smaller Long-Term Evolution (VoLTE) voice packets (mainly the overhead of the Physical Downlink Control Channel (PDCCH)), so that more resources can be used to schedule additional UEs.

[0048] The network configures the parameters required for DL ​​SPS for the UE through high-level signaling, such as the period, the number of hybrid automatic repeat request (HARQ) processes, the resources for HARQ-ACK feedback, etc. After the UE configures the DL SPS configuration, the base station activates the configured DL SPS configuration through downlink control information (DCI). The DCI will include transmission parameters such as the resources and modulation and coding scheme (MCS) for DL ​​SPS transmission. The UE determines the time of DL SPS transmission and the frequency resources at the corresponding time by receiving the activation DCI. At each DL SPS moment, the UE will listen to whether there is corresponding data transmission on the DL SPS resources.

[0049] If the network wants to release the allocated DL SPS resources, the base station can send a deactivation DCI to release the DL SPS resources.

[0050] In addition, the network can configure one or more DL SPS configuration resources for the UE to reduce latency, with the minimum SPS period being 1 slot.

[0051] HARQ-ACK timing is defined as the interval from the end of downlink data reception to the corresponding positive acknowledgment (ACK) or / negative acknowledgment (NACK) feedback. NR supports flexible HARQ-ACK timing configuration to suit different services and network deployments. Each UE can configure a UE-specific HARQ-ACK timing table through Radio Resource Control (RRC). The table contains multiple HARQ-ACK timing values, namely k1 values, where k1 is in units of slots. When dynamically scheduling downlink data transmission, the base station will indicate a k1 value in the DCI in an indexed manner. The k1 is a value in the UE-specific HARQ-ACK timing table, which is used to notify the UE of the time to feedback the HARQ-ACK.

[0052] For a DL SPS physical downlink shared channel (PDSCH) sent in slot n, its corresponding HARQ-ACK is transmitted on slot n+K, where K is indicated in the DCI that activates the DL SPS.

[0053] For the HARQ-ACK process that supports TB-level feedback, each transport block (TB) corresponds to a feedback HARQ-ACK bit. The UE needs to indicate its minimum HARQ processing time capability (the minimum HARQ processing time means the minimum time required to receive the corresponding HARQ-ACK transmission timing from the Downlink data). Asynchronous and adaptive Downlink HARQ are supported for eMBB and URLLC. From the UE's perspective, HARQ-ACK feedback for multiple PDSCHs can be transmitted in one uplink (UL) data / control region in time, forming a HARQ-ACK codebook on this UL time resource. The timing between PDSCH reception and the corresponding ACK / NACK is specified in the DCI.

[0054] In the related technology, 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 determines the HARQ-ACK codebook for all PDSCHs that may be fed back in a certain time slot according to the PDCCH monitoring opportunity (PDCCH monitoring accossion) configured by RRC, the PDSCH time domain resource allocation (PDSCH-TimeDomainResourceAllocation), the PDSCH to HARQ-ACK feedback timing (dl-DataToUL-ACK or PDSCH-toHARQ-timing) and other parameters. Since it may contain HARQ of actually scheduled and unscheduled PDSCH, its codebook is generally larger. For dynamic HARQ-ACK codebook, the UE determines the HARQ-ACK codebook based on the actually scheduled PDSCH. Since HARQ-ACK feedback is only performed on the actually scheduled PDSCH, the codebook size of its HARQ-ACK is usually smaller than the codebook size of the semi-static HARQ-ACK codebook. The specific type of codebook used by the UE is determined by RRC configuration.

[0055] In the related technology, the base station can configure one or more (up to 4) PUCCH resource sets (PUCCH resource sets) for each UE through RRC signaling. The RRC configures or predefines the maximum number of bits of the uplink control information (UCI) payload that each resource set (RESET) can carry (for example, the first RESET is up to 2 bits, the second and third RESETs are N1 and N2 respectively, and the fourth RESET is up to 1706 bits, N1 and N2 are RRC configurations), and each RESET can contain multiple PUCCH resources (the first RESET contains up to 32 PUCCH resources, and other RESETs each contain up to 8 PUCCH resources). On the UE side, after receiving the PDSCH, the UE needs to feedback HARQ-ACK. In order to determine the PUCCH resource where the feedback HARQ-ACK is located, the UE needs to first determine the time slot where the PUCCH is located through K1 in the PDCCH that schedules the PDSCH, and then determine the RESET where the PUCCH is located through the number of bits of the HARQ-ACK that needs to be fed back. In the determined RESET, 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 index (first CCE index) of the first control channel element (control channel element, CCE) of the PRI+PDCCH determines which PUCCH resource in the RESET (when the number of resources contained in the RESET exceeds 8). When there are multiple PDSCH HARQ-ACKs fed back in one slot, the UE determines the PUCCH resource based on the PRI and the minimum CCE index in the last DCI (last DCI) that schedules these PDSCHs.

[0056] In order to achieve flexible network deployment, the NR system configures the transmission direction of each symbol in a time slot by means of a slot format.

[0057] There are three definitions of the transmission direction of time slots in NR: downlink (DL), uplink (UL), and flexible. When the network configures a time slot or symbol as DL or UL, the transmission direction at that moment is clear; when the network configures a time slot or symbol as flexible, the transmission direction at that moment is undetermined. The network can modify the transmission direction of a flexible time slot or symbol through dynamic signaling, such as the dynamic slot format indicator (SFI).

[0058] like Figure 2 As shown, a slot may contain downlink, uplink and flexible Orthogonal Frequency Division Multiplexing (OFDM) symbols; Flexible symbols may be rewritten as downlink or uplink symbols.

[0059] For the convenience of description, a slot that includes all DL symbols is called a DL slot (i.e., D in the figure). A slot that includes all UL symbols is called a UL slot (i.e., U in the figure). A slot that includes all flexible symbols or a slot that includes DL, UL, and flexible symbols is called a special slot (i.e., F in the figure).

[0060] SFI (slot format indicator) can indicate the format of one or more slots. SFI is sent in the Group Common (GC)-PDCCH. SFI can flexibly change the slot format according to demand to meet service transmission requirements. The UE decides whether to monitor the PDCCH based on the indication of SFI.

[0061] The base station can semi-statically configure one or more cell-specific slot formats for the UE through the high-level parameter tdd-UL-DL-ConfigurationCommon. The base station can also semi-statically configure one or more UE-specific slot formats for the UE through the high-level 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.

[0062] The transmission directions implicitly indicated by the UE-specific RRC configuration are collectively referred to as measurements, including:

[0063] 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;

[0064] UE-specific RRC-configured physical random access channel (PRACH) resources, type 1 and type 2 unlicensed uplink transmission;

[0065] For type 2 unlicensed uplink transmission, only the transmission on the first activated resource is considered as UE-specific data. UE-specific transmission includes PDSCH, PUSCH, A / N feedback of PDSCH, aperiodic measurement triggered by DCI, etc.

[0066] In the relevant mechanism, the HARQ-ACK feedback time of each SPS configuration is indicated by the respective activation DCI, so the HARQ-ACK corresponding to the SPS PDSCH of different SPS configurations may be fed back at different times. If the HARQ-ACK feedback time corresponding to a SPS PDSCH conflicts with the DL, the HARQ-ACK of the SPS PDSCH will be discarded, resulting in a degradation in the performance of the SPS PDSCH.

[0067] The HARQ-ACK of the SPS PDSCH can be postponed to the subsequent uplink resource for transmission. However, this will cause multiple HARQ-ACKs to be concentrated on a certain uplink resource for transmission, resulting in a large uplink load and affecting uplink performance.

[0068] The present application embodiment provides a semi-static scheduling configuration method, such as Figure 3 As shown, including:

[0069] Step 101: The terminal receives a semi-persistent scheduling SPS configuration parameter, where the SPS configuration parameter includes at least one of the following:

[0070] The delay parameter i of the time slot n where the SPS downlink resource is received is used to indicate the i-th available uplink time slot after the first time slot, where the first time slot is the time slot n+k1 after the time slot n passes through k1 time slots, i is a positive integer, and k1 is a non-negative integer;

[0071] 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 of the time slot n of receiving the cluster of SPS downlink resources is the time slot for HARQ-ACK feedback;

[0072] A reference time window, wherein the second uplink time slot in which the HARQ-ACK feedback of each SPS downlink resource is received is determined according to the reference time window.

[0073] The SPS downlink resources are OFDM symbols occupied by the SPS PDSCH in one slot and frequency domain resources, which may be indicated by the activation DCI.

[0074] In an embodiment of the present application, the network side device sends SPS configuration parameters to the terminal. 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 the transmission of HARQ-ACK corresponding to SPS PDSCH when the UE is configured with SPS transmission, thereby improving the performance of DL SPS PDSCH transmission.

[0075] The SPS downlink resource reception is to receive the SPS downlink resource, that is, to receive the SPS downlink resource.

[0076] In some embodiments, if the SPS configuration parameter includes a delay parameter i, the method further includes:

[0077] 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.

[0078] In some embodiments, the delay parameter i takes effect after the terminal receives activation downlink control information DCI of the SPS configuration parameters.

[0079] 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 time slot n2 of the second resource, the delay parameter i corresponding to the first resource is i1, and the delay parameter i corresponding to the second resource is i2, then the k1+i1th time slot after time slot n1 is earlier than or equal to the k1+i2th time slot after time slot n2.

[0080] 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 indicated by the network for HARQ-ACK transmission of the PDSCH of an SPS is an unavailable time slot, the UE will determine the UL slot for transmitting the HARQ-ACK according to the delay parameter i. The delay parameter i represents the i-th available UL slot after an SPS PDSCH is received after k1slot.

[0081] Of course, k1 can also be a sub-slot granularity.

[0082] In a specific embodiment, Figure 5As shown, when a HARQ-ACK feedback of an SPS PDSCH encounters an unavailable time slot (for example, a PUCCH resource encounters a DL or unavailable flexible symbol), the HARQ-ACK feedback of the SPS PDSCH will be delayed for transmission, and the delay parameter i can be characterized as delaying the transmission to the i-th available UL slot. Through this operation, the HARQ-ACK of some SPS PDSCHs can be delayed to the first available UL slot after the time slot corresponding to k1, the HARQ-ACK of some SPS PDSCHs can be delayed to the second available UL slot after the time slot corresponding to k1, and the HARQ-ACK of some SPS PDSCHs can be delayed to the n-th available UL slot after the time slot corresponding to k1, where n is an integer greater than 2, thereby achieving load balancing.

[0083] Furthermore, the delay parameter i may be configured or indicated per time T_P, for example,

[0084] T_P=N*cycle, N>=1. In a specific example, T_P=M*(sub-)slot, M>=1.

[0085] T_P may be related to SCS, that is, the value of T_P may be different for different SCS.

[0086] For any two SPS PDSCHs of an SPS configuration, if the slot of the kth SPS PDSCH appears 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, which can be the same slot or the previous slot to avoid out-of order execution.

[0087] In some embodiments, if the SPS configuration parameter includes the k1 value corresponding to each cluster of SPS downlink resources, the method further includes:

[0088] Receive second indication information, where the second indication information is used to indicate that the k1 value corresponding to a cluster of SPS downlink resources is: the 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.

[0089] In this embodiment, for an SPS configuration, the k1 value can be configured per slot by activating the DCI indication. 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.

[0090] In a specific embodiment, Figure 6As shown, for 7 SPS PDSCHs in an SPS configuration, the network side indicates respective k1 values. In this embodiment, the network side indicates 2 different k1 values: k1_1 and k1_2.

[0091]

[0092] In this way, the HARQ-ACK of the PDSCH of different SPSs are grouped according to the indicated k1 value. The first cluster is the PDSCH of the SPS of slots 0-3, and the second cluster is the PDSCH of the SPS of slots 4-6.

[0093] Furthermore, the network side may configure a period, cluster divisions within the period and corresponding k1set sets, and when a k1set is indicated by activation or reactivation DCI, the k1s in the k1set are applied to each cluster in turn.

[0094] For example, the network side configuration period is 10ms, cluster 1 includes slot 0-slot 3, and cluster 2 includes slot 4-slot 6.

[0095] The corresponding k1 set is

[0096] Codepoint k1set 00 {k1_1, k1_2} 01 {k1_3, k1_4} 10 {k1_5, k1_6} 11 {k1_7, k1_8}

[0097] Activate or reactivate k1set in the DCI indication table. The two values ​​in k1set are applied to cluster 1 and cluster 2 respectively.

[0098] The network side can configure the k1 value used by the HARQ-ACK of the PDSCH of an SPS in a cluster to indicate the k1 value of the HARQ-ACK of the first, 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 as a valid k1 value. For the first cluster, the HARQ-ACK of the last SPS PDSCH in the cluster: k1=5; for the second cluster, the HARQ-ACK of the last SPS PDSCH in the cluster: k1=2.

[0099] In addition, the network side needs to ensure that when changing different time slot configurations, the indicated k1 value should be a valid k1 value.

[0100] In some embodiments, the SPS configuration parameters further include:

[0101] The first indication information is used to indicate that if the first time slot is an unavailable time slot, feedback on SPS downlink resource reception is postponed to the first available time slot.

[0102] In some embodiments, if the first time slot includes at least part of unavailable flexible symbols and conflicts with PUCCH resources carrying HARQ-ACK feedback, the first time slot is an unavailable time slot; or

[0103] If the first time slot includes at least part of the downlink symbols and conflicts with the PUCCH resources carrying HARQ-ACK feedback, the first time slot is an unavailable time slot.

[0104] In this embodiment, for an SPS configuration, the HARQ-ACK transmission of the PDSCH of the SPS is determined by the k1 value indicated by the network side as an unavailable time slot, and the UE will delay the HARQ-ACK transmission to an available slot. When the delayed slot encounters a slot containing all or part of the flexible symbols, one way is: high-level signaling configures whether the slot is an available time slot, such as configuring a set or subset of available resources (such as UL slot or a self-contained slot of both UL, DL and flexible symbols) through RRC, and all slots in the set are valid resources, that is, available slots, which can be used to feedback HARQ-ACK; another way is: the slots determined by the indicated k1 value are all regarded as available time slots, and HARQ-ACK resources can be fed back. That is, if the PUCCH resource for feedback 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 indication (such as activating DCI) are valid resources, and PUCCH can be transmitted.

[0105] In addition, if the SFI indicates that a slot containing all or part of the flexible symbols is an available time slot, the time slot can be used for HARQ-Ack feedback. If the UE does not receive the SFI, when it encounters a slot containing all or part of the flexible symbols, the time slot is regarded as an unavailable resource, and the UE looks for the next available slot.

[0106] In a specific embodiment, when the format of a slot conflicts with the PUCCH resource of the HARQ-ACK of an SPS PDSCH, the slot may be referred to as an unavailable 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, if OFDM i~j has any 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 encountering a slot containing all or part of the flexible symbols, the slot is regarded as an available resource (for 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 may be regarded as an unavailable resource. Both methods may be configured by the network or determined according to the frequency band characteristics, such as an unlicensed band or a licensed band.

[0107] 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 some flexible symbols, the method further includes:

[0108] Receive third indication information from the network side device, where the third indication information is used to indicate whether the first available time slot is a valid resource on which feedback can be performed, and feedback of the received SPS downlink resource can be performed on the valid resource.

[0109] In some embodiments, the method further comprises:

[0110] Receive fourth indication information from the network side device, which is used to indicate that the flexible symbols in the first time slot are valid resources that can be used for feedback, and the received SPS downlink resources can be fed back on the valid resources.

[0111] In some embodiments, if the SPS configuration parameter includes a reference time window, the method further includes:

[0112] The SPS downlink resources corresponding to each uplink time slot are determined according to the number of uplink time slots and the number of SPS downlink resources in the reference time window. The SPS downlink resources perform HARQ-ACK feedback in the corresponding uplink time slot. The number of SPS downlink resources corresponding to different uplink time slots can be allocated according to predefined rules. For example, the difference in the number of SPS downlink resources corresponding to different uplink time slots is not greater than 1.

[0113] The number of SPS downlink resources may be the number of SPS downlink resources configured by the network side, or the number of valid SPS downlink resources. Both methods may be configured by the network side.

[0114] If the symbol of a slot conflicts with the symbol of the SPS downlink resources, these SPS downlink resources are not valid SPS downlink resources.

[0115] 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. For non-valid SPS downlink resources, NACK is fed back, and for valid SPS downlink resources, HARQ-ACK information is fed back.

[0116] In this embodiment, the network side configures a reference time window T, including a starting slot index and the length of the time window, and determines the UL slot for HARQ-ACK feedback of each SPS PDSCH according to the number of UL slots within T indicated by the network high-level parameter (tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated) and the number of configured SPS PDSCHs, so that the number of SPS PDSCHs corresponding to each UL slot is almost the same. In this slot, the PUCCH resources indicated by the network for the SPS (activate DCI or network configuration) are used for feedback.

[0117] The network side configures the time window T, and can configure at least one of the starting radio frame, subframe, slot, offset (offset of radio frame, subframe, or slot) and period L (period of radio frame, subframe or slot), for example, for 15kHz subcarrier spacing:

[0118] A configuration of the time window T is as follows: the starting radio frame is 0, the offset is 0, and the period is 1 radio frame;

[0119] Another configuration of the time window T is to start at radio frame 0, have an offset of 1 subframe, and a period of 10 subframes;

[0120] Another configuration of the time window T is to start at radio frame 0, have an offset of 1 slot, and a period of 10 slots.

[0121] In a specific embodiment, if within the time window T, for N valid SPS PDSCHs, the determined UL slots are Q, the SPS PDSCHs are divided into Q groups as evenly as possible, the maximum difference in the number of SPS PDSCHs in each group is 1, and the SPS PDSCHs in each group are arranged in order from large to small (or reverse order).

[0122] For example: the network side configures an SPS configuration period of 1 slot. Assuming that the time window T is 10ms long, for the first T1, the semi-static UL slot in the time window is 2. To determine the UL time slot for feedback HARQ-ACK, the UE will determine the HARQ-ACK feedback of the SPS PDSCH based on the number of configured SPS configurations and the number of UL slots.

[0123] Such as Figure 7 As shown, the PUCCH of the U1 time slot feeds back the HARQ-ACK bits of the first 4 SPS of the time window T1, and the PUCCH of the U2 time slot feeds back the HARQ-ACK bits of the last 3 SPS. The HARQ-ACK of the first 3 SPS of the time window T2 is fed back in U3, and so on.

[0124] 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 the F time slot is not a time slot containing valid SPS downlink resources. The time slot (slot F) containing flexible symbols in T2 can transmit SPS PDSCH.

[0125] Furthermore, within the reference time window T, if the UL symbol part in the time slot containing the flexible symbol can be used to transmit the HARQ-ACK of the SPS, then it can also be counted in the UL slot. If the DL symbol part in the time slot containing the flexible symbol can transmit the SPS downlink resource, then the SPS downlink resource is a valid SPS downlink resource.

[0126] Further, T=P (provided by pattern 1 and can be configured by tdd-UL-DL-ConfigurationCommon), or T=P+P2 (provided by pattern 1 and pattern 2 respectively and can be configured by tdd-UL-DL-ConfigurationCommon).

[0127] Optionally, the network side may determine the cluster according to the number of switching points within the time T. Figure 8 As shown, there are three UL-DL switching points in time T, which are divided into 3 clusters.

[0128] The number of SPS PDSCHs fed back by a UL slot in each cluster is distributed as evenly 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 maximum difference in the number of SPS PDSCHs fed back by any UL slot is 1. Similarly, if the UL symbol part in the time slot containing flexible symbols can be used to transmit the HARQ-ACK of SPS, it can also be counted in the UL slot.

[0129] It is worth noting that the above scheme can be applied to the case of multiple SPS configurations. The above technical solution of this embodiment can be used in LTE systems, and can also be extended to unlicensed frequency bands, scenarios where HARQ-ACK cannot be sent due to carrier listening (Listen Before Talk, LBT), such as time division duplex (TDD) or frequency division duplex (FDD) scenarios in unlicensed frequency bands.

[0130] The present application embodiment provides a semi-static scheduling configuration method, such as Figure 4 As shown, including:
