[0096] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0097] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0098] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0099] The LTE system can support semi-persistent scheduling. For example, the LTE system notifies the terminal of information about semi-persistent scheduling through RRC signaling, and then notifies the terminal when to start semi-persistent scheduling through the PDCCH channel.

[0100] However, the efficiency of notifying the terminal of the semi-persistent scheduling information through RRC signaling is low and cannot meet the needs of the development of communication technology.

[0101] In the 3rd Generation Partnership Project (3GPP) evolution standard (Release 16, R16) protocol version, for semi-continuous scheduling, although multiple SPS configurations are supported, only one SPS can be activated at a time. When multiple SPS configurations need to be activated, multiple DCI (Downlink Control Information) commands need to be sent.

[0102] In the discussion of R17, the standard decided to support the function of one DCI to schedule up to 8 PDSCHs at the same time in high frequency (the specific number of PDSCHs scheduled is determined by the base station). How to activate multiple SPS configurations with one DCI based on the time domain resource assignment (TDRA) configured by RRC signaling is an important issue that the industry needs to solve urgently.

[0103] For example: in the 52.6GHz~71GHz frequency band, it supports control and data channels with a subcarrier spacing (SCS) of 480 / 960KHz, and also supports one DCI) to schedule multiple PDSCHs. Among them, one DCI can schedule up to 8 PDSCHs at the same time, or less than 8 PDSCHs, which is determined by the RRC configuration. In R16, multiple SPS configurations are supported, but only one SPS can be activated at a time. When multiple SPS configurations need to be activated, multiple commands need to be sent; the activation indication is shown in the following Table 1 (where the DCI is scrambled with the configured scheduling-radio network temporary identifier (ConfiguredScheduling-Radio Network Temporary Identifier, CS-RNTI)):

[0104] Table 1 shows the DCI field settings for activating an SPS configuration (CS-RNTI scrambled DCI), as shown in Table 1:

[0105] Table 1

[0106]

[0107]

[0108] Among them, μ is used to represent the minimum SCS configuration between the SCS configuration of the PDCCH providing the SPS PDSCH release and the SCS configuration of the uplink control channel (Physical Uplink Control Channel, PUCCH) carrying the hybrid automatic repeat request confirmation character (Hybrid Automatic Repeat Request-Acknowledge character, HARQ-ACK) information in response to the SPS PDSCH release.

[0109] The parameters for configuring SPS by RRC are shown in Table 2 below:

[0110] Table 2 shows the parameter list of RRC configuration SPS (sps-ConfigIndex-r16), as shown in Table 2:

[0111] Table 2

[0112]

[0113] The embodiments of the present application provide a channel scheduling method, device, apparatus and storage medium, wherein each SPS corresponds to a PDSCH transmission, and multiple SPS configurations are activated through DCI, wherein the DCI indicates the number of activated or retransmitted SPSs, and the information bit used by the HARQ process number of the DCI is used to indicate the first activated SPS or the SPS activation list, thereby achieving flexibility in PDSCH scheduling and more convenient configuration of the SPS.

[0114] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system, etc. These various systems include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0116] The terminal device involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless TU loop (WLL) stations, personal digital assistants (PDAs) and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, and a user device, but is not limited in the embodiments of the present application.

[0117] The network device involved in the embodiment of the present application may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names.

The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (Home evolved Node B, HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0118] Network devices and terminal devices can each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoded transmission or beamforming transmission, etc.

[0119] Figure 1 It is one of the flow charts of the channel scheduling method provided in the embodiment of the present application. The channel scheduling method can be used in network equipment, such as: base station; Figure 1 As shown, the channel scheduling method may include the following steps:

[0120] Step 101: Determine control signaling, where the control signaling is used to indicate PDSCHs of N SPSs, where N is an integer greater than or equal to 1.

[0121] Specifically, the control signaling of the PDSCH for indicating N SPSs may be DCI signaling or other types of control signaling.

[0122] If the control signaling is a DCI signaling, the DCI signaling may refer to control signaling for simultaneously scheduling PDSCHs of multiple SPSs, that is, one DCI signaling may simultaneously schedule PDSCHs of multiple SPSs. For example, one DCI signaling may simultaneously schedule PDSCHs of 8 SPSs or PDSCHs of less than 8 SPSs.

[0123] Step 102: Send control signaling to the terminal device, so that the terminal device determines the PDSCH of N SPSs according to the control signaling.

[0124] Specifically, after configuring the control signaling, the network device may send the control signaling to the terminal device, so that after receiving the control signaling, the terminal device may determine the PDSCH of N SPSs according to the control signaling.

[0125] Among them, if the control signaling is DCI signaling, the network device can send the DCI signaling to the terminal device after configuring the DCI signaling, so that after the terminal device receives the DCI signaling, it can determine the PDSCH of N SPS according to the DCI signaling.

[0126] For example, if the DCI signaling simultaneously schedules the PDSCH of 8 SPS or the PDSCH of less than 8 SPS, the terminal device may determine the PDSCH of 8 SPS or the PDSCH of less than 8 SPS according to the DCI signaling.

[0127] It can be seen from the above embodiments that by determining the control signaling, the control signaling is used to indicate the PDSCH of N SPSs, where N is an integer greater than or equal to 1; the control signaling is sent to the terminal device, so that the terminal device determines the PDSCH of N SPSs according to the control signaling, thereby achieving that one control signaling can simultaneously schedule the PDSCH of multiple SPSs, thereby improving the efficiency of channel scheduling.

[0128] Optionally, the control signaling includes TDRA identification information for indicating the time domain position of the PDSCH of the N SPSs, the TDRA identification information is a row index pointing to a TDRA table, each row in the TDRA table includes multiple start and length information values ​​(Start and Length Indicator Value, SLIV).

[0129] Specifically, the TDRA identification information may point to a row in the TDRA table, and if the row includes multiple SLIVs, it may be used to determine the multiple SLIVs used by the SPS configuration. For example, the TDRA table includes three rows, with row indexes of 0, 1, and 2, respectively; each row has eight SLIVs, namely SLIV1, SLIV2, ..., SLIV8.

[0130] Furthermore, valid values ​​(ie, non-invalid values) corresponding to the multiple SLIVs used in the SPS configuration indicate the time domain positions of the PDSCHs of the N SPSs.

[0131] In addition, the TDRA identification information may be located in a time domain resource assignment field in the DCI signaling.

[0132] It is worth noting that, in the embodiment of the present application, one or more TDRA tables configured by the network device may be included, and the TDRA table pointed to by the TDRA identification information may be a specific TDRA table among the one or more TDRA tables.

[0133] It can be seen from the above embodiments that by configuring the TDRA identification information through the network device, the time domain position of the PDSCH of N SPS can be better found, that is, the TDRA identification information points to a row in the TDRA table, and the valid value (that is, non-invalid value) indicates the time domain position of the PDSCH of N SPS; at the same time, the TDRA table configured by the network device can more conveniently indicate the time domain position of the PDSCH, thereby improving the efficiency of determining the time domain position of the PDSCH of N SPS.

[0134] Optionally, the channel scheduling method further includes:

[0135] Determine a first high-level signaling, where the first high-level signaling is used to indicate a TDRA table, where each row in the TDRA table includes a plurality of SLIVs;

[0136] The first high-layer signaling is sent to the terminal device, so that the terminal device obtains the TDRA table according to the first high-layer signaling.

[0137] Specifically, the first high-layer signaling for indicating the TDRA table may be a first RRC signaling, or a Medium Access Control-Control Element (MAC-CE), or other high-layer signaling.

[0138] For example: the first high-level signaling is the first RRC signaling, and the network device can configure the TDRA table to the terminal in advance through the first RRC signaling, so that when the terminal receives the control signaling (for example, DCI signaling) of the PDSCH for indicating N SPSs, it can determine the multiple SLIVs used for the SPS configuration from the TDRA table indicated by the first RRC signaling according to the row index indicated by the control signaling (for example, DCI signaling).

[0139] For example, the TDRA table is shown in Table 3, which includes three rows with row indexes of 0, 1, and 2; each row has 8 SLIVs, namely SLIV1, SLIV2, ..., SLIV8.

[0140] Table 3

[0141]

[0142] Among them, K0 represents the time slot offset value, S represents the value of the starting symbol index, L represents the symbol length value, Invalid represents invalid, SLIV represents the start and length information value, and the number k that follows (k can be any digit from 1 to 8) is the time slot number. The time slot index is determined by K0 and the time slot number. The time slot index is calculated starting from the time slot number n where the DCI is located, n+K0+k-1.

[0143] It can be seen from the above embodiments that the TDRA table is sent to the terminal device through the first high-level signaling, so that the terminal device can obtain the TDRA table through the first high-level signaling, and then determine the multiple SLIVs used by the SPS configuration according to the row index indicated by the control signaling, thereby improving the accuracy of determining the time domain position of the PDSCH of N SPSs.

[0144] Optionally, the control signaling also includes first identification information for indicating the first activated SPS among the N SPSs, and the first identification information is an SPS index pointing to the SPS configuration parameter set.

[0145] Specifically, the first identification information may indicate the first activated SPS among the N SPSs, and other SPSs among the N SPSs may be indirectly determined through the first identification information.

[0146] For example, if the SPS identifier of the first activated SPS is 1, the SPS identifier of the second activated SPS is 2, the SPS identifier of the third activated SPS is 3, and so on.

[0147] For another example, if the SPS identifier of the first activated SPS is 1, the SPS identifier of the second activated SPS is 3, the SPS identifier of the third activated SPS is 5, and so on.

[0148] The SPS configuration parameter set pointed to by the first identification information may refer to the parameter list of the RRC configuration SPS shown in the above Table 2. The SPS index of the SPS configuration parameter set may refer to the SPS configuration index (sps-ConfigIndex-r16) in the above Table 2.

[0149] It is worth noting that, in an embodiment of the present application, one or more SPS configuration parameter sets of the network device configuration may be included, and the SPS configuration parameter set pointed to by the first identification information may be a specific SPS configuration parameter set among the one or more SPS configuration parameter sets.

[0150] The network device may send the SPS configuration parameter set to the terminal device in advance through high-level signaling, for example: the network device may send the SPS configuration parameter set to the terminal device in advance through the first high-level signaling for indicating the TDRA table, that is, the first high-level signaling includes the SPS configuration parameter set. For another example: the network device may send the SPS configuration parameter set to the terminal device in advance through another high-level signaling different from the first high-level signaling, that is, the signaling for indicating the SPS configuration parameter set is a separate signaling.

[0151] The first identification information may be located in the HARQ process ID field of the DCI signaling, such as the HARQ process ID field shown in Table 4.

[0152] Table 4

[0153]

[0154]

[0155] It can be seen from the above embodiments that the first activated SPS among N SPSs is indicated by the first identification information, so that the terminal device can determine the SPS identification of each activated SPS among the N SPSs according to the first identification information and the set rules, thereby improving the efficiency of SPS configuration.

[0156] Optionally, the parameters in the SPS configuration parameter set include a Hybrid Automatic Repeat Request (HARQ) process number offset value, and the HARQ process number offset value is used to determine the HARQ process numbers of N SPSs.

[0157] Specifically, the SPS configuration parameter set may refer to the parameter list of the RRC configuration SPS shown in the above Table 2. The HARQ process number offset value of the SPS configuration parameter set may refer to the HARQ process number offset value in the above Table 2, namely: HARQ-ProcID-Offset-r16, INTEGER (0..15).

[0158] When determining the HARQ process numbers of the N SPSs, the HARQ process numbers may be determined according to the HARQ process number offset value and the setting rule. The following two determination methods may be included but are not limited to:

[0159] Method 1: assigning a HARQ process number to the first activated SPS among multiple SPSs, and sequentially assigning the HARQ process number corresponding to the previous SPS among the multiple SPSs plus 1 to the next SPS until each activated SPS among the multiple SPSs is assigned a HARQ process number;

[0160] If it is determined that the number of allocated HARQ process numbers is less than the maximum number of HARQ process numbers, the last allocated HARQ process number plus 1 is allocated to the first activated SPS among the multiple SPSs, and the HARQ process number corresponding to the previous SPS among the multiple SPSs is increased by 1 and allocated to the next SPS in turn, and the number of allocated HARQ processes is updated until the updated number of allocated HARQ process numbers is equal to the maximum number of HARQ process numbers.

[0161] For example: assuming there are a total of 8 HARQ process numbers, namely 1, 2, 3, 4, 5, 6, 7, and 8; and 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3, and PDSCH-4; when allocating 8 HARQ process numbers, 1 and 5 can be allocated to PDSCH-1, 2 and 6 can be allocated to PDSCH-2, 3 and 7 can be allocated to PDSCH-3, and 4 and 8 can be allocated to PDSCH-4.

[0162] Method 2: Divide the maximum HARQ process number evenly to each SPS among N SPSs, and the number of process numbers of each SPS is Q. All HARQ process numbers in the first range are allocated to the first activated SPS among multiple SPSs, and all HARQ process numbers in the second range corresponding to the previous SPS among multiple SPSs are allocated to the next SPS in turn, until each activated SPS among multiple SPSs is allocated with a HARQ process number; wherein Q is a value greater than 1, the first range includes the HARQ process number to the HARQ process number plus Q-1, and the second range includes the last process number corresponding to the previous SPS plus 1 to plus Q.

[0163] For example: assuming there are a total of 8 HARQ process numbers, namely 1, 2, 3, 4, 5, 6, 7, and 8; and 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3, and PDSCH-4; when allocating 8 HARQ process numbers, 1 and 2 can be allocated to PDSCH-1, 3 and 4 can be allocated to PDSCH-2, 5 and 6 can be allocated to PDSCH-3, and 7 and 8 can be allocated to PDSCH-4.

[0164] It can be seen from the above embodiments that the HARQ process numbers of N SPSs can be determined by the HARQ process number offset value, thereby ensuring that one DCI signaling can schedule the PDSCHs of multiple SPSs at the same time.

[0165] Optionally, the control signaling also includes second identification information for indicating all activated SPSs among the N SPSs, and the second identification information is an SPS list index pointing to the SPS activation list.

[0166] Specifically, the second identification information may indicate all activated SPSs among N SPSs.

[0167] The SPS activation list pointed to by the second identification information may refer to an SPS activation list configured by the network device through RRC signaling. The SPS activation list may include SPS identifications of all activated SPSs in the N SPSs.

[0168] For example, three SPS identifiers are configured in the SPS activation list, namely SPS-ID=2, SPS-ID=3, and SPS-ID=5.

[0169] It is worth noting that, in an embodiment of the present application, one or more SPS activation lists configured by the network device may be included, and the SPS activation list pointed to by the second identification information may be a specific SPS activation list among the one or more SPS activation lists.

[0170] The network device may send the SPS activation list to the terminal device in advance through high-layer signaling, for example: the network device may send the SPS activation list to the terminal device in advance through the first high-layer signaling for indicating the TDRA table, that is, the first high-layer signaling includes the SPS activation list. Another example: the network device may send the SPS activation list to the terminal device in advance through another high-layer signaling different from the first high-layer signaling, that is, the signaling for indicating the SPS activation list is a separate signaling.

[0171] The second identification information may be located in the HARQ process ID field of the control signaling, such as the HARQ process ID field shown in Table 5.

[0172] Table 5

[0173]

[0174]

[0175] It can be seen from the above embodiments that through the second identification information of all activated SPSs in N SPSs, the terminal device can directly determine the SPS identification of each activated SPS in N SPSs according to the SPS activation list pointed to by the second identification information, thereby improving the flexibility of SPS configuration.

[0176] Optionally, the channel scheduling method further includes:

[0177] Determine a second higher layer signaling, where the second higher layer signaling is used to indicate an SPS activation list;

[0178] The second higher layer signaling is sent to the terminal device, so that the terminal device obtains the SPS activation list according to the second higher layer signaling.

[0179] Specifically, the network device may send the SPS activation list to the terminal device via a second high-layer signaling, wherein the second high-layer signaling may be the same as or different from the first high-layer signaling for indicating the TDRA table.

[0180] The second high-layer signaling used to indicate the SPS activation list may be a second RRC signaling, or may be a MAC-CE, or may be other high-layer signaling.

[0181] In addition, the network device may be configured with multiple SPS activation lists, and the SPS activation list here may be one of the multiple SPS activation lists.

[0182] For each SPS activation list: a maximum of a first number (ie, maxNrofSPS-ActivationState) of activation states can be configured, and the parameters of each activation state are configured by the SPS configuration activation state (ie, SPS-ConfigAactivationState), and a maximum of a second number (ie, maxNrofSPS-Config) of SPS PDSCHs are included.

[0183] It can be seen from the above embodiments that the SPS activation list can be sent to the terminal device through the second high-level signaling, so that the terminal device can obtain the SPS activation list from the second high-level signaling, and then determine the SPS identifier of each activated SPS among N SPSs, thereby improving the accuracy of the SPS configuration.

[0184] Optionally, the control signaling includes one or more of RV, NDI and K1 indication;

[0185] Among them, RV is all 0; NDI is all 0; K1 indication includes:

[0186] When activated, K1 is the time slot position of the uplink control channel PUCCH calculated from the position of the last scheduled PDSCH among the PDSCHs of N SPSs;

[0187] During data transmission, K1 calculates the respective PUCCH time slot position from each PDSCH of the N SPSs.

[0188] K1 is used to represent the feedback timing indicator from PDSCH to HARQ.

[0189] Specifically, the RV may be located in the redundancy version number field shown in Table 4 or Table 5, and its value may be all zeros.

[0190] NDI may be located in the new data indication field shown in Table 4 or Table 5, and its value may be all 0s.

[0191] K1 may be located in the PDSCH-to-HARQ_feedback timing indicator field shown in Table 4 or Table 5.

[0192] The K1 indication may include but is not limited to the following two situations:

[0193] Case 1: When multiple SPSs are activated under multi-PDSCH scheduling, K1 is calculated from the position of the last scheduled PDSCH among the PDSCHs of N SPSs.

[0194] Case 2: When PDSCH data of N SPSs is transmitted, K1 calculates the PUCCH time slot position of each PDSCH in the N SPSs.

[0195] It can be seen from the above embodiments that by indicating RV, NDI and K1 through control signaling, the terminal device can obtain the RV, NDI and K1 indicated by the network device from the control signaling, thereby improving the accuracy of channel scheduling.

[0196] Figure 2 2 is a flow chart of a channel scheduling method provided in an embodiment of the present application. The channel scheduling method can be used in a terminal device; Figure 2 As shown, the channel scheduling method may include the following steps:

[0197] Step 201: Receive control signaling sent by a network device, where the control signaling is used to indicate PDSCHs of N SPSs, where N is an integer greater than or equal to 1.

[0198] Specifically, the control signaling of the PDSCH for indicating N SPSs may be DCI signaling or other types of control signaling.

[0199] If the control signaling is a DCI signaling, the DCI signaling may refer to control signaling for simultaneously scheduling PDSCHs of multiple SPSs, that is, one DCI signaling may simultaneously schedule PDSCHs of multiple SPSs. For example, one DCI signaling may simultaneously schedule PDSCHs of 8 SPSs or PDSCHs of less than 8 SPSs.

[0200] Step 202: Determine the PDSCH of N SPSs according to the control signaling.

[0201] Specifically, after receiving the control signaling, the terminal device can determine the PDSCH of N SPSs according to the control signaling.

[0202] Among them, if the control signaling is DCI signaling, after receiving the DCI signaling, the terminal device can determine the PDSCH of N SPSs according to the DCI signaling.

[0203] For example, if the DCI signaling simultaneously schedules PDSCHs of 8 SPS or PDSCHs of less than 8 SPS, the terminal device may determine PDSCHs of 8 SPS or PDSCHs of less than 8 SPS according to the DCI signaling.

[0204] It can be seen from the above embodiments that by receiving the control signaling sent by the network device, the control signaling is used to indicate the PDSCH of N SPSs, where N is an integer greater than or equal to 1, thereby achieving that one control signaling can simultaneously schedule the PDSCH of multiple SPSs, thereby improving the efficiency of channel scheduling.

[0205] Optionally, the control signaling includes TDRA identification information for indicating the time domain position of the PDSCH of the N SPSs, the TDRA identification information is a row index pointing to a TDRA table, and each row in the TDRA table includes multiple SLIVs.

[0206] Specifically, the TDRA identification information may point to a row in the TDRA table, and if the row includes multiple SLIVs, it may be used to determine the multiple SLIVs used by the SPS configuration.

[0207] For example: The TDRA table consists of three rows, with row indexes of 0, 1, and 2; each row has 8 SLIVs, namely SLIV1, SLIV2, ..., SLIV8.

[0208] Furthermore, valid values ​​(ie, non-invalid values) corresponding to the multiple SLIVs used in the SPS configuration indicate the time domain positions of the PDSCHs of the N SPSs.

[0209] In addition, the TDRA identification information may be located in a time domain resource assignment field in the control signaling.

[0210] It is worth noting that, in the embodiment of the present application, one or more TDRA tables configured by the network device may be included, and the TDRA table pointed to by the TDRA identification information may be a specific TDRA table among the one or more TDRA tables.

[0211] It can be seen from the above embodiments that the time domain position of the PDSCH of N SPS can be better found through the TDRA identification information, that is, the TDRA identification information points to a row in the TDRA table, and the valid value (that is, non-invalid value) indicates the time domain position of the PDSCH of N SPS, thereby improving the efficiency of determining the time domain position of the PDSCH of N SPS.

[0212] Optionally, the channel scheduling method further includes:

[0213] receiving a first high-level signaling sent by a network device, where the first high-level signaling is used to indicate a TDRA table;

[0214] The TDRA table is obtained according to the first higher layer signaling.

[0215] Specifically, the first high-layer signaling used to indicate the TDRA table may be the first RRC signaling, may also be MAC-CE, or may be other high-layer signaling.

[0216] For example: the first high-level signaling is the first RRC signaling. When the terminal receives the control signaling (for example, DCI signaling) of the PDSCH for indicating N SPSs, it can determine the multiple SLIVs used for the SPS configuration from the TDRA table indicated by the first RRC signaling according to the row index indicated by the DCI signaling.

[0217] For example, the TDRA table is shown in Table 6, which includes three rows with row indexes of 0, 1, and 2; each row has 8 SLIVs, namely SLIV1, SLIV2, ..., SLIV8.

[0218] Table 6

[0219]

[0220]

[0221] Among them, K0 represents the time slot offset value, S represents the value of the starting symbol index, L represents the symbol length value, Invalid represents invalid, SLIV represents the start and length information value, and the number k that follows (k can be any digit from 1 to 8) is the time slot number. The time slot index is determined by K0 and the time slot number. The time slot index is calculated starting from the time slot number n where the DCI is located, n+K0+k-1.

[0222] It can be seen from the above embodiment that the TDRA table is obtained through the first high-layer signaling, and then the multiple SLIVs used by the SPS configuration are determined according to the row index indicated by the control signaling, thereby improving the accuracy of determining the time domain positions of the PDSCHs of N SPSs.

[0223] Optionally, the control signaling further includes first identification information for indicating the first activated SPS among the N SPSs, and the first identification information is an SPS index pointing to the SPS configuration parameter set. Correspondingly, when executing step 202, it may specifically include but is not limited to the following implementation process:

[0224] a. Determine the SLIV value corresponding to each SLIV index pointed to by the TDRA identification information according to the TDRA table, where the SLIV value includes a valid value or an invalid value;

[0225] b. Determine the N activated SPSs according to the number of valid values ​​in each SLIV index;

[0226] c. determining the SPS identifier of each activated SPS in the N SPSs according to the first identifier information;

[0227] d. Determine the correspondence between the SPS identifier of each activated SPS in the N SPSs and the valid values ​​in each SLIV index according to the first setting rule;

[0228] e. Determine the HARQ process number of each activated SPS among the N SPSs according to the second setting rule.

[0229] Specifically, when determining the N activated SPSs, as shown in Table 6, when the row index is 0, SLIV1, SLIV2, ..., SLIV8 are all valid values; when the row index is 1, SLIV1, SLIV2 and SLIV4 are invalid values, and the rest are valid values; when the row index is 2, SLIV2, SLIV3 and SLIV4 are invalid values, and the rest are valid values. If the first identification information is 0, the number of valid values ​​is 8, indicating that the control signaling indicates the activation of 8 SPSs; if the first identification information is 1 or 2, the number of valid values ​​is 5, indicating that the control signaling indicates the activation of 5 SPSs.

[0230] When determining the SPS identifier of each activated SPS among N SPSs according to the first identifier information, the first identifier information can indicate the first activated SPS among the N SPSs, and the other SPSs among the N SPSs can be indirectly determined by the first identifier information. For example: if the SPS identifier of the first activated SPS is 1, then the SPS identifier of the second activated SPS is 2, the SPS identifier of the third activated SPS is 3, and so on. For another example: if the SPS identifier of the first activated SPS is 1, then the SPS identifier of the second activated SPS is 3, the SPS identifier of the third activated SPS is 5, and so on.

[0231] The first identification information may be located in the HARQ process ID field of the control signaling, such as the HARQ process ID field shown in Table 4 above.

[0232] The first setting rule and the second setting rule may be specified by the communication protocol, or may be configured in advance by the network device to the terminal device through signaling.

[0233] In addition, the SPS configuration parameter set pointed to by the first identification information may refer to the parameter list of the RRC configuration SPS shown in the above Table 2. The SPS index of the SPS configuration parameter set may refer to the SPS configuration index (sps-ConfigIndex-r16) in the above Table 2.

[0234] It is worth noting that, in an embodiment of the present application, one or more SPS configuration parameter sets of the network device configuration may be included, and the SPS configuration parameter set pointed to by the first identification information may be a specific SPS configuration parameter set among the one or more SPS configuration parameter sets.

[0235] It can be seen from the above embodiments that the SPS identifier of each activated SPS among N SPSs, the correspondence between the SPS identifier of each activated SPS and the valid values ​​in each SLIV index, and the HARQ process number of each activated SPS among N SPSs can be determined respectively by the first identification information, the first setting rule and the second setting rule, thereby ensuring that one control signaling can schedule the PDSCH of multiple SPSs at the same time, thereby improving the reliability of channel scheduling.

[0236] Optionally, the parameters in the SPS configuration parameter set include a HARQ process number offset value, and the HARQ process number offset value is used to determine the HARQ process numbers of the N SPSs;

[0237] (1) The first setting rule may include:

[0238] The SPS identifier of the first activated SPS among the N SPSs corresponds to the first valid value in each SLIV index;

[0239] The SPS identifier of the Mth activated SPS among the N SPSs corresponds to the Mth valid value in each SLIV index, where M is an integer greater than 1 and less than or equal to N, and the SPS identifier of the Mth activated SPS is the first identifier information plus a set value;

[0240] Among them, if the time slot where the first valid value is located is an uplink time slot, the first activated SPS cannot be used to schedule data;

[0241] If the time slot where the Mth valid value is located is an uplink time slot, the Mth activated SPS cannot be used for scheduling data.

[0242] Specifically, the set value can be M-1, for example: the first identification information is 1, the SPS identification of the second activated SPS is 2, the SPS identification of the third activated SPS is 3, and so on; it can also be other values, for example: the first identification information is 1, the SPS identification of the second activated SPS is 3, the SPS identification of the third activated SPS is 5, and so on.

[0243] When determining the corresponding relationship according to the first setting rule, Figure 3 As shown:

[0244] Method 1: Assuming that the SLIV index value range is 1 to 4 and SLIV2 is invalid, the corresponding SPS-ID 2 is not activated and SPS-ID 1 / 3 / 4 is activated.

[0245] Method 2: Assuming that the SLIV index value range is 1 to 4 and SLIV2 is invalid, SPS-ID2 is activated but the time domain position corresponds to SLIV3; SPS-ID3 is activated but the time domain position corresponds to SLIV4, and SPS-ID4 is not activated.

[0246] When the corresponding relationship is determined according to the first setting rule, for the uplink time slot, such as Figure 4 As shown:

[0247] TDRA={row index 0: SLIV-1(S=2, L=10), SLIV-2((S=2, L=10), SLIV-3(S=2, L=10), SLIV-4(S=2, L=10)}.

[0248] Assume that the SLIV index value range is 1 to 4, SLIV-2 (i.e. Figure 4 The SLIV indicated by number 5 is the uplink time slot, then SPS-ID=2 is activated but no data is scheduled.

[0249] (2) The second setting rule includes the following method 1 or method 2:

[0250] Method 1: assigning a HARQ process number to the first activated SPS among multiple SPSs, and sequentially assigning the HARQ process number corresponding to the previous SPS among the multiple SPSs plus 1 to the next SPS until each activated SPS among the multiple SPSs is assigned a HARQ process number;

[0251] If it is determined that the number of allocated HARQ process numbers is less than the maximum number of HARQ process numbers, the last allocated HARQ process number plus 1 is allocated to the first activated SPS among the multiple SPSs, and the HARQ process number corresponding to the previous SPS among the multiple SPSs is increased by 1 and allocated to the next SPS in turn, and the number of allocated HARQ processes is updated until the updated number of allocated HARQ process numbers is equal to the maximum number of HARQ process numbers.

[0252] For example: assuming there are a total of 8 HARQ process numbers, namely 1, 2, 3, 4, 5, 6, 7, and 8; and 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3, and PDSCH-4; when allocating 8 HARQ process numbers, 1 and 5 can be allocated to PDSCH-1, 2 and 6 can be allocated to PDSCH-2, 3 and 7 can be allocated to PDSCH-3, and 4 and 8 can be allocated to PDSCH-4, as shown in method 1 in Table 7 below.

[0253] Table 7

[0254]

[0255] Method 2: Divide the maximum HARQ process number evenly to each SPS among N SPSs, and the number of process numbers of each SPS is Q. All HARQ process numbers in the first range are allocated to the first activated SPS among multiple SPSs, and all HARQ process numbers in the second range corresponding to the previous SPS among multiple SPSs are allocated to the next SPS in turn, until each activated SPS among multiple SPSs is allocated with a HARQ process number; wherein Q is a value greater than 1, the first range includes the HARQ process number to the HARQ process number plus Q-1, and the second range includes the last process number corresponding to the previous SPS plus 1 to plus Q.

[0256] For example: assuming there are a total of 8 HARQ process numbers, namely 1, 2, 3, 4, 5, 6, 7, and 8; and 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3, and PDSCH-4; when allocating 8 HARQ process numbers, 1 and 2 can be allocated to PDSCH-1, 3 and 4 can be allocated to PDSCH-2, 5 and 6 can be allocated to PDSCH-3, and 7 and 8 can be allocated to PDSCH-4 as shown in method 2 in Table 7 above.

[0257] It can be seen from the above embodiments that the HARQ process numbers of N SPSs are determined by the HARQ process number offset value, thereby ensuring that one control signaling can schedule the PDSCHs of multiple SPSs at the same time, thereby improving the flexibility of channel scheduling.

[0258] Optionally, the control signaling further includes second identification information for indicating all activated SPSs in the N SPSs, where the second identification information is an SPS list index pointing to the SPS activation list; correspondingly, when executing step 202, it may specifically include but is not limited to the following implementation process:

[0259] a. Determine the SLIV value corresponding to each SLIV index pointed to by the TDRA identification information according to the TDRA table, where the SLIV value includes a valid value or an invalid value;

[0260] b. Determine, according to the SPS activation list, each SPS identifier pointed to by the second identifier information;

[0261] c. Determine the N activated SPSs according to the total number of SPS identifiers;

[0262] d. Determine the SPS identifier of each activated SPS in the N SPSs according to each SPS identifier;

[0263] e. Determine the correspondence between the SPS identifier of each activated SPS in the N SPSs and the valid values ​​in each SLIV index according to the third setting rule;

[0264] f. Determine the HARQ process number of each activated SPS among the N SPSs according to the fourth setting rule.

[0265] Specifically, as shown in Table 6, when the row index is 0, SLIV1, SLIV2, ..., SLIV8 are all valid values; when the row index is 1, SLIV1, SLIV2 and SLIV4 are invalid values, and the rest are valid values; when the row index is 2, SLIV2, SLIV3 and SLIV4 are invalid values, and the rest are valid values.

[0266] The second identification information may indicate all activated SPSs among the N SPSs.

[0267] The SPS activation list pointed to by the second identification information may refer to an SPS activation list configured by the network device through high-level signaling. The SPS activation list may include SPS identifications of all activated SPSs in the N SPSs.

[0268] For example, three SPS identifiers are configured in the SPS activation list, namely SPS-ID=2, SPS-ID=3, and SPS-ID=5.

[0269] The second identification information may be located in the HARQ process ID field of the control signaling, such as the HARQ process ID field shown in Table 5 above.

[0270] It is worth noting that, in an embodiment of the present application, one or more SPS activation lists configured by the network device may be included, and the SPS activation list pointed to by the second identification information may be a specific SPS activation list among the one or more SPS activation lists.

[0271] The third setting rule and the fourth setting rule may be specified by the communication protocol, or may be configured in advance by the network device to the terminal device through signaling.

[0272] Among them, (1) the third setting rule includes:

[0273] The Pth SPS identifier in each SPS identifier corresponds to the Pth valid value in each SLIV index, where P is an integer greater than or equal to 1 and less than or equal to N;

[0274] If the time slot where the Pth valid value is located is an uplink time slot, the Pth activated SPS cannot be used to schedule data;

[0275] When determining the corresponding relationship according to the third setting rule, if Figure 5 As shown: Assuming that the SLIV index value range is 1 to 5, SLIV2 is invalid, and the SPS activation list pointed to by the second identification information is configured with SPS-ID=2 / 3 / 5, then SLIV1 corresponds to SPS-ID2, SLIV3 corresponds to SPS-ID3, and SLIV4 corresponds to SPS-ID5.

[0276] When the corresponding relationship is determined according to the third setting rule, for the uplink time slot, as described above Figure 4 As shown:

[0277] TDRA={row index 0: SLIV-1(S=2, L=10), SLIV-2((S=2, L=10), SLIV-3(S=2, L=10), SLIV-4(S=2, L=10)}.

[0278] Assume that the SLIV index value range is 1 to 4, SLIV-2 (i.e. Figure 4 The SLIV indicated by number 5 is the uplink time slot, then SPS-ID=2 is activated but no data is scheduled.

[0279] (2) The fourth setting rule includes the following method 1 or method 2:

[0280] Method 1: assigning a HARQ process number to the first activated SPS among multiple SPSs, and sequentially assigning the HARQ process number corresponding to the previous SPS among the multiple SPSs plus 1 to the next SPS until each activated SPS among the multiple SPSs is assigned a HARQ process number;

[0281] If it is determined that the number of allocated HARQ process numbers is less than the maximum number of HARQ process numbers, the last allocated HARQ process number plus 1 is allocated to the first activated SPS among the multiple SPSs, and the HARQ process number corresponding to the previous SPS among the multiple SPSs is increased by 1 and allocated to the next SPS in turn, and the number of allocated HARQ processes is updated until the updated number of allocated HARQ process numbers is equal to the maximum number of HARQ process numbers.

[0282] For example: assuming there are a total of 8 HARQ process numbers, namely 1, 2, 3, 4, 5, 6, 7, and 8; and 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3, and PDSCH-4; when allocating 8 HARQ process numbers, 1 and 5 can be allocated to PDSCH-1, 2 and 6 can be allocated to PDSCH-2, 3 and 7 can be allocated to PDSCH-3, and 4 and 8 can be allocated to PDSCH-4, as shown in method 1 in Table 7 above.

[0283] Method 2: Divide the maximum HARQ process number evenly to each SPS among the N SPSs, and the number of process numbers of each SPS is Q. Allocate each HARQ process number within the third range to the first activated SPS among the multiple SPSs, and sequentially allocate each HARQ process number within the fourth range corresponding to the previous SPS among the multiple SPSs to the next SPS, until each activated SPS among the multiple SPSs is allocated a HARQ process number; wherein Q is a value greater than 1, the third range includes the HARQ process number to the HARQ process number plus Q-1, and the fourth range includes the last process number corresponding to the previous SPS plus 1 to plus Q.

[0284] For example: assuming there are a total of 8 HARQ process numbers, namely 1, 2, 3, 4, 5, 6, 7, and 8; and 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3, and PDSCH-4; when allocating 8 HARQ process numbers, 1 and 2 can be allocated to PDSCH-1, 3 and 4 can be allocated to PDSCH-2, 5 and 6 can be allocated to PDSCH-3, and 7 and 8 can be allocated to PDSCH-4 as shown in method 2 in Table 7 above.

[0285] It can be seen from the above embodiments that the SPS identifier of each activated SPS among N SPSs, the correspondence between the SPS identifier of each activated SPS and the valid values ​​in each SLIV index, and the HARQ process number of each activated SPS among N SPSs can be determined respectively through the second identification information, the third setting rule and the fourth setting rule, thereby ensuring that one control signaling can schedule the PDSCH of multiple SPSs at the same time, thereby improving the reliability of channel scheduling.

[0286] Optionally, the channel scheduling method further includes:

[0287] receiving a second high-layer signaling sent by a network device, where the second high-layer signaling is used to indicate an SPS activation list;

[0288] The SPS activation list is obtained according to the second higher layer signaling.

[0289] Specifically, the terminal device receives the second high-level signaling sent by the network device, and can obtain the SPS activation list according to the second high-level signaling. The second high-level signaling can be the same as or different from the first high-level signaling for indicating the TDRA table.

[0290] The second high-layer signaling used to indicate the SPS activation list may be a second RRC signaling, or may be a MAC-CE, or may be other high-layer signaling.

[0291] In addition, the network device may be configured with multiple SPS activation lists, and the SPS activation list here may be one of the multiple SPS activation lists.

[0292] For each SPS activation list: a maximum of a first number (ie, maxNrofSPS-ActivationState) of activation states can be configured, and the parameters of each activation state are configured by the SPS configuration activation state (ie, SPS-ConfigAactivationState), and a maximum of a second number (ie, maxNrofSPS-Config) of SPS PDSCHs are included.

[0293] It can be seen from the above embodiments that the SPS activation list can be obtained from the second high-layer signaling, and then the SPS identifier of each activated SPS in the N SPSs can be determined, thereby improving the accuracy of the SPS configuration.

[0294] Optionally, the control signaling includes one or more of RV, NDI and K1 indication;

[0295] Among them, RV is all 0; NDI is all 0; K1 indication includes:

[0296] When activated, K1 calculates the timeslot position of the PUCCH from the position of the last scheduled PDSCH among the PDSCHs of N SPSs;

[0297] During data transmission, K1 calculates the respective PUCCH time slot position from each PDSCH of the N SPSs.

[0298] Specifically, the RV may be located in the redundancy version number field shown in Table 4 or Table 5, and its value may be all zeros.

[0299] NDI may be located in the new data indication field shown in Table 4 or Table 5, and its value may be all 0s.

[0300] K1 may be located in the PDSCH-to-HARQ_feedback timing indicator field shown in Table 4 or Table 5.

[0301] Among them, Figure 6 K1 indication may include but is not limited to the following two situations:

[0302] Case 1: When multiple SPSs are activated under multi-PDSCH scheduling, K1 calculates the timeslot position of the PUCCH from the position of the last scheduled PDSCH among the PDSCHs of the N SPSs;

[0303] Case 2: When PDSCH data of N SPSs is transmitted, K1 calculates the PUCCH time slot position of each PDSCH in the N SPSs.

[0304] It can be seen from the above embodiments that the RV, NDI and K1 indicated by the network device can be obtained through control signaling, thereby improving the accuracy of channel scheduling.

[0305] The implementation process of the above channel scheduling method will be illustrated by two examples below.

[0306] Example 1:

[0307] The DCI signaling includes TDRA identification information and first identification information.

[0308] Among them, the TDRA identification information is a row index pointing to the TDRA table, and each row in the TDRA table includes multiple SLIVs; the first identification information is used to indicate the first activated SPS among N SPSs, and is an SPS index pointing to the SPS configuration parameter set.

[0309] The first identification information may be located in the HARQ process ID field of the DCI signaling, such as the HARQ process ID field shown in Table 4.

[0310] The specific implementation process includes:

[0311] (1-1) The base station sets a TDRA table configured by an SPS, wherein each row of the TDRA table has multiple SLIV values.

[0312] (1-2) When DCI is scrambled using CS-RNTI, the TDRA table configured by SPS is used.

[0313] (1-3) The base station determines the multiple SLIVs used in the SPS configuration through the TDRA indication row index of the DCI.

[0314] (1-4) The terminal device reads the DCI and determines the number of activated SPSs and the corresponding SLIV value.

[0315] (1-5) The base station indicates the first activated SPS-ID through the first identification information of the DCI, which corresponds to the valid value of the first SLIV. The SPS-IDs of other scheduled PDSCHs are increased by 1, which correspond to other valid values ​​of SLIV in turn.

[0316] (1-6) The terminal device determines the activated multiple SPS-IDs and related configuration parameters by reading the DCI.

[0317] (1-7) If there are invalid conditions in all SLIVs of the row index indicated in step (1-3), then:

[0318] Method 1: The SPS-ID corresponding to the invalid SLIV is not activated, and the SPS-ID and SLIV correspond to each other in sequence.

[0319] Specifically, Figure 3 Method 1 shown:

[0320] TDRA = {row index 0: SLIV-1 (S = 2, L = 10), SLIV-2 (invalid), SLIV-3 (S = 2, L = 10), SLIV-4 (S = 2, L = 10)}. Assuming that the SLIV index value range is 1 to 4, and SLIV2 is invalid, the corresponding SPS-ID 2 is not activated, and SPS-ID 1 / 3 / 4 is activated.

[0321] Method 2: The SPS-ID corresponding to the invalid SLIV is activated, and the corresponding SLIV is delayed to a valid SLIV value.

[0322] Specifically, Figure 3 Method 2 shown:

[0323] Assuming that the SLIV index value range is 1 to 4 and SLIV2 is invalid, SPS-ID 2 is activated but the time domain position corresponds to SLIV3; SPS-ID3 is activated but the time domain position corresponds to SLIV4, and SPS-ID4 is not activated.

[0324] (1-8) If there is an uplink time slot in all SLIVs of the row index (Row index) indicated in step (1-3), then: the SPS-ID corresponding to the uplink time slot is valid for activation this time, but the scheduling is invalid for this time.

[0325] Specifically, Figure 4 As shown:

[0326] Among them, TDRA = {row index 0: SLIV-1 (S = 2, L = 10), SLIV-2 ((S = 2, L = 10), SLIV-3 (S = 2, L = 10), SLIV-4 (S = 2, L = 10)}.

[0327] Assume that the SLIV index value range is 1 to 4, SLIV-2 (i.e. Figure 4 The SLIV indicated by number 5 is the uplink time slot, then SPS-ID=2 is activated but no data is scheduled.

[0328] (1-9)HARQ process allocation.

[0329] Specifically, method 1: assigning a HARQ process number to the first activated SPS among multiple SPSs, and sequentially assigning the HARQ process number corresponding to the previous SPS among the multiple SPSs plus 1 to the next SPS until each activated SPS among the multiple SPSs is assigned a HARQ process number;

[0330] If it is determined that the number of allocated HARQ process numbers is less than the maximum number of HARQ process numbers, the last allocated HARQ process number plus 1 is allocated to the first activated SPS among the multiple SPSs, and the HARQ process number corresponding to the previous SPS among the multiple SPSs is increased by 1 and allocated to the next SPS in turn, and the number of allocated HARQ processes is updated until the updated number of allocated HARQ process numbers is equal to the maximum number of HARQ process numbers.

[0331] For example: assuming there are a total of 8 HARQ process numbers, namely 1, 2, 3, 4, 5, 6, 7, and 8; and 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3, and PDSCH-4; when allocating 8 HARQ process numbers, 1 and 5 can be allocated to PDSCH-1, 2 and 6 can be allocated to PDSCH-2, 3 and 7 can be allocated to PDSCH-3, and 4 and 8 can be allocated to PDSCH-4, as shown in method 1 in Table 7 above.

[0332] Method 2: Divide the maximum HARQ process number evenly to each SPS among N SPSs, and the number of process numbers of each SPS is Q. All HARQ process numbers in the first range are allocated to the first activated SPS among multiple SPSs, and all HARQ process numbers in the second range corresponding to the previous SPS among multiple SPSs are allocated to the next SPS in turn, until each activated SPS among multiple SPSs is allocated with a HARQ process number; wherein Q is a value greater than 1, the first range includes the HARQ process number to the HARQ process number plus Q-1, and the second range includes the last process number corresponding to the previous SPS plus 1 to plus Q.

[0333] For example: assuming there are a total of 8 HARQ process numbers, namely 1, 2, 3, 4, 5, 6, 7, and 8; and 4 PDSCHs, namely PDSCH-1, PDSCH-2, PDSCH-3, and PDSCH-4; when allocating 8 HARQ process numbers, 1 and 2 can be allocated to PDSCH-1, 3 and 4 can be allocated to PDSCH-2, 5 and 6 can be allocated to PDSCH-3, and 7 and 8 can be allocated to PDSCH-4 as shown in method 2 in Table 7 above.

[0334] (1-10) When activated, the K1 value is calculated from the position of the last PDSCH scheduled to calculate the PUCCH time slot position. During data transmission, the K1 value is calculated for each PDSCH separately, such as Figure 6 shown.

[0335] Example 2:

[0336] The DCI signaling includes TDRA identification information and second identification information.

[0337] Among them, the TDRA identification information is a row index pointing to the TDRA table, and each row in the TDRA table includes multiple SLIVs; the second identification information is used to indicate all activated SPSs in N SPSs, and is an SPS list index pointing to the SPS activation list.

[0338] The second identification information may be located in the HARQ process ID field of the DCI signaling, such as the HARQ process ID field shown in Table 4.

[0339] The specific implementation process includes:

[0340] (2-1) The base station sets a TDRA table configured by an SPS, wherein each row of the TDRA table has multiple SLIV values.

[0341] (2-2) When DCI is scrambled using CS-RNTI, the TDRA table configured by SPS is used.

[0342] (2-3) The base station determines the multiple SLIVs used in the SPS configuration through the TDRA indication row index of the DCI.

[0343] (2-4) The terminal device reads the DCI and determines the SLIV value corresponding to the activated SPS.

[0344] (2-5) The base station configures the SPS activation list through RRC.

[0345] The SPS configuration activation state list SPS-ConfigActivationStateList can configure up to maxNrofSPS-ActivationState activation states. The parameters of each activation state are configured by SPS-ConfigAactivationState, which contains up to maxNrofSPS-Config SPS PDSCHs. The description is as follows:

[0346] SPS-ConfigActivationStateList-r16::=SEQUENCE(SIZE(1..maxNrofSPS-ActivationState))OF SPS-ConfigActivationState-r16

[0347] SPS-ConfigAactivationState-r16::=SEQUENCE(SIZE(1..maxNrofSPS-Config-r16))OF SPS-ConfigIndex-r16

[0348] (2-6) The base station indicates the SPS list index of the activated SPS activation list through the second identification information of the DCI.

[0349] (2-7) The terminal device determines the SPS list index and related configuration parameters of the activated SPS activation list by reading the DCI.

[0350] (2-8) If there is an invalid situation in all SLIVs of the row index indicated in step (2-3), then:

[0351] An invalid SLIV does not correspond to an SPS-ID, and the SPS-ID indicated by the RRC and the valid SLIV value correspond in sequence.

[0352] Specifically, Figure 5As shown: Assuming that the SLIV index value range is 1 to 5, SLIV2 is invalid, and SPS-ID=2 / 3 / 5 is configured in the SPS list ID, then SLIV1 corresponds to SPS-ID2, SLIV3 calls SPS-ID3, and SLIV4 corresponds to SPS-ID5.

[0353] (2-9) Same as Example 1, if there is an uplink time slot in all SLIVs of the row index (Row index) indicated in step (2-3), then: the SPS-ID corresponding to the uplink time slot is valid for activation this time, but the scheduling is invalid this time.

[0354] (2-10) The HARQ process allocation is the same as in Example 1 and will not be repeated here.

[0355] (2-11) Same as Example 1, when activated, the K1 value is calculated from the position of the last PDSCH scheduled to calculate the PUCCH time slot position. During data transmission, the K1 value is calculated for each PDSCH separately to calculate the PUCCH time slot position.
