Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, in particular, the present application relates to a semi-persistent scheduling method, a base station device and a user equipment. BACKGROUND

[0002] Ultra-reliable low-latency communication (URLLC) proposed in 5G puts forward the demand of delay and reliability at the same time, 3GPP Rel-15 can support less than 1ms end-to-end delay and 10 -5 -1 block error rate. With the growth of industry internet of things (Industry Internet of things), AR and VR business, more stringent requirements are also put forward for URLLC, for example, 3GPP Rel-16 learns more demanding URLLC, which requires support for 0.5ms-1ms end-to-end delay and 10 -6 -1 block error rate. This brings challenges to the communication system of NR. At present, the method of semi-persistent scheduling (SPS) transmission or the method of configured grant (CG) transmission in the NR system is an important way to support URLLC service. In the existing NR system research, the minimum period of downlink SPS is 10ms, which obviously cannot meet the delay requirement of 0.5ms-1ms. The minimum period of uplink CG transmission can be 2 symbols, but the length of time resources that can be used for K times of continuous CG transmission (K is the repetition number) cannot be greater than the period of CG transmission. For example, if the base station configures the period P of CG transmission to be 7 symbols, assuming that the time length of a PUSCH transmission is 2 symbols, then the base station can configure K=3 times of repetition at most, so that the time length of K times of repeated CG PUSCH does not exceed the period. In addition, the uplink CG transmission also limits the starting position of a CG transmission to be related to RV, for example, the UE can only start uplink transmission at the transmission opportunity (TO) with RV=0. If the base station configures the RV sequence as {0, 0, 0, 0}, then the UE can start transmission at any TO within the configured CG resource, and the waiting delay is small. But if the base station configures the RV sequence as {0, 2, 3, 1}, then the UE can only start transmission every 3 TOs, and the waiting delay is relatively prolonged. If the period P is large, such as Figure 1As shown, the CG transmission period P=1 slot, the RV sequence is {0, 2, 3, 1}, K=4, and each CG PUSCH occupies 2 symbols. The uplink data arrival time of the UE is the second symbol in the first period, so the UE needs to wait until the first TO of the next period to start transmission, introducing a delay of 13 symbols, which cannot meet the low latency requirement of URLLC. How to improve the existing CG transmission mechanism to support higher low latency requirement is a problem to be solved.

[0003] In addition, in the existing NR system, only one SPS configuration / CG configuration is supported, and it is obviously difficult to support the URLLC requirements of multiple services. For example, in industrial Internet of Things, a terminal can simultaneously support monitoring sensors and robot arms. These URLLC services have different characteristics, such as different latency and traffic requirements. In order to simultaneously support multiple services, multiple SPS configurations can be introduced, and different time-frequency domain resources can be allocated to each SPS configuration. How to efficiently and flexibly configure and schedule multiple SPS configurations is also a problem to be solved. SUMMARY

[0180] Next, the semi-static scheduling method of the above embodiments of the present application will be fully and thoroughly introduced through the following specific embodiments:

[0181] Specifically, based on the SPS / CG transmission, at least one of the following ways can be implemented: way one, the base station configures all semi-static scheduling parameters through high layer signaling; the UE considers that the semi-static scheduling is activated after receiving the configuration information of all semi-static scheduling parameters, and can perform SPS / CG reception or transmission on the corresponding time-frequency resource according to the configuration information; if the base station releases an SPS / CG transmission through high layer signaling, the UE stops performing SPS / CG reception or transmission on the corresponding time-frequency resource after receiving the configuration information of releasing an SPS / CG. For the convenience of description, this kind of SPS / CG transmission is referred to as the first type of SPS / CG transmission. Way two, the base station configures part of the semi-static scheduling parameters through high layer signaling, and activates the SPS / CG transmission through a physical layer control channel, such as downlink control information (DCI), and indicates the remaining semi-static scheduling parameters; the UE can perform SPS / CG reception or transmission on the corresponding time-frequency resource after receiving the configuration information of part of the semi-static scheduling parameters and the activation DCI; if the base station deactivates an SPS / CG transmission through DCI, the UE stops performing SPS / CG reception or transmission on the corresponding time-frequency resource after receiving the deactivation DCI. For the convenience of description, this kind of SPS / CG transmission is referred to as the second type of SPS / CG transmission.

[0182] Embodiment one

[0183] In the prior art, for the first type of SPS / CG transmission, if the semi-static scheduling parameters need to be changed, the base station needs to send high layer signaling to reconfigure all semi-static scheduling parameters. For example, for uplink CG PUSCH transmission, the high layer signaling rrc-ConfiguredUplinkGrant information includes time resource, frequency domain resource, antenna port information, reference signal DMRS signal, MIMO related information, modulation and coding information (MCS and TBS), and power control information, etc. Generally, the delay of reconfiguration through high layer RRC signaling is large. If the first type of SPS / CG transmission needs to feed back the hybrid automatic repeat request acknowledgement HARQ-ACK, the high layer signaling also needs to configure the parameters related to HARQ-ACK feedback, such as HARQ-ACK feedback time information and PUCCH resource information.

[0184]

[0185] To change the semi-persistent scheduling parameters more flexibly and control the physical layer control signaling overhead within a reasonable range, the transmission parameter reconfiguration can be performed by a method combining high layer signaling configuration and DCI dynamic indication. Specifically, two sets of semi-persistent scheduling parameters can be configured by high layer signaling, and one of the two sets of semi-persistent scheduling parameters is indicated by X bits in DCI. X The two sets of semi-persistent scheduling parameters are configured by high layer signaling, and one of the two sets of semi-persistent scheduling parameters is indicated by X bits in DCI.

[0186] Preferably, the high layer signaling configures two sets of semi-persistent scheduling parameters. X One of the two sets of semi-persistent scheduling parameters is used for the first time after activation, or the two sets of semi-persistent scheduling parameters are pre-defined. X The first set of the two sets of semi-persistent scheduling parameters is used for the first time after activation. Subsequently, the base station can dynamically indicate the second set of the two sets of semi-persistent scheduling parameters by DCI. X One of the two sets of semi-persistent scheduling parameters is used for the first time after activation, or the two sets of semi-persistent scheduling parameters are pre-defined.

[0187] Preferably, the semi-persistent scheduling parameters at least include one of frequency domain resource information, time domain resource information (such as period, symbol start point, symbol length, time offset, etc.), modulation and coding information.

[0188] Preferably, if the base station configures multiple sets of SPS / CG configurations for the UE, one DCI can indicate the semi-persistent scheduling parameters of multiple sets of SPS / CG configurations at the same time, the number and / or index of the SPS / CG configurations indicated in the DCI need to be configured, and for each set of SPS / CG configuration, X bits are used to indicate two sets of semi-persistent scheduling parameters. Xone of the sets of semi-persistent scheduling parameters. Preferably, X is a standard predefined or configurable value, wherein X can be 0 or other positive integers, and when X = 0, the number of semi-persistent scheduling parameters is 1. Preferably, the maximum number of SPS / CG configurations indicated by the DCI is a standard predefined value, or the maximum payload of the DCI is a standard predefined value. For example, the base station configures 4 sets of SPS configurations with indexes 0, 1, 2, 3 respectively, and configures 4 sets of semi-persistent scheduling parameters for each set of SPS configurations. The DCI has a total of 8 bits, and for each SPS configuration, 2 bits with values 0-3 correspond to the 1st-4th sets of semi-persistent scheduling parameters respectively. If the SPS configuration is configured on multiple carriers, in order to distinguish the SPS configurations of each carrier, different SPS configuration indexes can be assigned to distinguish them, or carrier information and SPS configuration indexes can be used to distinguish them. It should be noted that the base station configures the same or different number of sets of semi-persistent scheduling parameters for each set of SPS configurations, for example, the base station configures 2 sets of semi-persistent scheduling parameters for the first set of SPS configurations, 4 sets of semi-persistent scheduling parameters for the second set of SPS configurations, 2 sets of semi-persistent scheduling parameters for the third set of SPS configurations, and 4 sets of semi-persistent scheduling parameters for the fourth set of SPS configurations.

[0189] More preferably, if one DCI can indicate multiple sets of SPS / CG configuration's semi-persistent scheduling parameters, the UE sends HARQ-ACK feedback after receiving the DCI. In one implementation, the DCI indicates the PUCCH resource for sending HARQ-ACK, such as the hybrid automatic repeat request acknowledgement timing and the PUCCH time-frequency resource. In another implementation, the higher layer signaling configures the PUCCH resource for sending HARQ-ACK, or the higher layer signaling configures the PUCCH resource for HARQ-ACK for each set of SPS / CG configuration, and the UE determines the PUCCH resource for HARQ-ACK of the DCI according to the PUCCH resource for HARQ-ACK of one set of SPS / CG configuration in the DCI. More preferably, the PUCCH resource for HARQ-ACK of the DCI is determined according to the PUCCH resource for HARQ-ACK of the configuration with the smallest SPS / CG configuration index and / or the smallest index of the multiple sets of semi-persistent scheduling parameters of the SPS / CG configuration.

[0190] In the prior art, for the second type of SPS / CG transmission, if it is necessary to change part of the semi-persistent scheduling parameters, the base station can reconfigure by sending the activation DCI again, or the base station also needs to reconfigure by sending the higher layer signaling. For example, the activation DCI can reconfigure the time resource, the frequency domain resource, the antenna port information, the reference signal DMRS signal, the MIMO related information, the modulation and coding information, and the power control information, etc. In order to save the physical layer control channel overhead, achieve the balance between flexibility and the reliability of the control channel, the above described method can also be used to activate / deactivate or change the semi-persistent scheduling parameters of the second type of SPS / CG transmission.

[0191] More preferably, if one DCI can activate multiple sets of SPS / CG configuration, the number and / or index of the SPS / CG configuration indicated in the DCI need to be configured, and for each SPS / CG configuration, 2 X sets of semi-persistent scheduling parameters are configured, respectively, and X bits are used to indicate 2 X sets of semi-persistent scheduling parameters. In the process of configuring 2 X sets of semi-persistent scheduling parameters for each SPS / CG configuration, the number of sets of semi-persistent scheduling parameters configured for each SPS / CG configuration is the same or different.

[0192] More preferably, if one DCI can activate / deactivate multiple sets of SPS / CG configurations simultaneously, the number and / or index of SPS / CG configurations indicated in this DCI need to be configured, and for each set of SPS / CG configuration configuration (2 X -1) sets of semi-persistent scheduling parameters, respectively corresponding to the state values 1~(2 X -1) of X bits in the DCI, and the reserved state value "0" indicates to deactivate this SPS / CG configuration. Wherein, in the process of configuring (2 X -1) sets of semi-persistent scheduling parameters for each set of SPS / CG configuration, the number of sets of semi-persistent scheduling parameters for each set of SPS / CG configuration is the same or different.

[0193] More preferably, for one set of SPS / CG configuration, multiple bit fields in the DCI correspond to different types of semi-persistent scheduling parameters, and each bit field corresponds to one or more sets of semi-persistent scheduling parameters. The semi-persistent scheduling parameters are configured by higher layer signaling, and one set of semi-persistent scheduling parameters is dynamically indicated by the corresponding bit field in the DCI. For example, the DCI contains 2 bit fields, one of which is used to indicate the frequency domain resource, with a total of X1 bits, and the base station configures 2 X1 frequency domain resource parameters; the other bit field is used to indicate the time resource, with a total of X2 bits, and the base station configures 2 X2 frequency domain resource parameters.

[0194] Embodiment two

[0195] In some scenarios, e.g., supporting different service types, the parameters of multiple sets of SPS / CG configurations are different. In other scenarios, the characteristics of multiple sets of SPS / CG configurations are similar or the same, and one set of signaling can be used to configure the same / common transmission parameters in these SPS / CG configurations. For example, in order to reduce latency, multiple sets of SPS / CG configurations can be configured for the same URLLC service type. For another example, in order to solve the problem that the period of a time-sensitive service (TSN) is not an integer multiple of the period of an SPS / CG configuration, multiple sets of SPS / CG configurations can be configured for the same TSN service. The multiple sets of SPS / CG configurations have the same frequency domain resources, modulation and coding information, and period, but the starting positions of the time domain are different, e.g., there is a time offset between the PDSCHs or PUSCHs of the multiple sets of SPS / CG configurations. The time offset can be on the order of a symbol (e.g., in units of OFDM symbols), or on the order of a slot, sub-slot, or absolute time, e.g., X microseconds (which can not be an integer multiple of the length of an OFDM symbol).

[0196] In one implementation, when configuring the multiple sets of SPS / CG configurations, only one set of common parameters, e.g., frequency domain resources, modulation and coding information, and period, can be configured, and the corresponding time resources, e.g., time offsets on the granularity of a slot, and / or the starting positions and lengths (number of symbols) of PDSCHs / PUSCHs in a slot, are configured for each set of SPS / CG configurations.

[0197] In another implementation, when configuring the multiple sets of SPS / CG configurations, only one set of common parameters can be configured, and an additional time offset between the sets of SPS / CG configurations is configured. The time characteristics in the common parameters, e.g., time offsets on the granularity of a slot, starting symbols and lengths of PDSCHs / PUSCHs, are only applicable to the first set of SPS / CG configurations in the multiple sets of SPS / CG configurations, and the time resources of PDSCHs / PUSCHs of other SPS / CG configurations are determined by the time resources of PDSCHs / PUSCHs of the first set or the previous set of SPS / CG configurations and the time offset between the sets of SPS / CG configurations.

[0198] In addition, the number and / or index of the multiple SPS / CG configurations need to be configured.

[0199] like Figure 3 As shown, the base station is configured with four CG configurations, using a single signaling system to indicate frequency domain resources, time domain resources, pilot information (DMRS), MCS, and TBS. The time domain resource information indicates a period of one time slot and specifies the number of time slots offset from the first CG configuration relative to system frame SFN=0. For example, it might be offset by 15 time slots relative to SFN0, which would be the 6th time slot in SFN1. The time domain resource information also indicates that the first CG configuration occupies symbols 3 through 6 of these time slots, with a repetition count K=1. The base station also configures a time offset of 2 symbols between each CG configuration. Therefore, starting from time slot 15, symbols 3 through 6 of each time slot represent the resources of the first CG configuration (#1CG in the diagram), symbols 5 through 8 represent the resources of the second CG configuration (#2CG in the diagram), symbols 7 through 10 represent the resources of the third CG configuration (#3CG in the diagram), and symbols 9 through 11 represent the resources of the fourth CG configuration (#4CG in the diagram).

[0200] Preferably, within a single cycle, the transmitter can attempt to transmit PDSCH / PUSCH on the time resources of multiple SPS / CG configurations. The time resources of these multiple SPS / CG configurations do not overlap. For example, a base station may configure three SPS PDSCH configurations with identical frequency domain resources, cycles, start points and symbol lengths within a downlink time unit, pilot information (DMRS), MCS, and TBS. The time offsets of these three SPS PDSCH configurations are configured to 0, 16, and 33 time slots, respectively. If the base station activates the transmission of these three SPS PDSCH configurations, the base station can transmit PDSCH on the resources of each of these three SPS PDSCH configurations.

[0201] More preferably, in a period, the transmitter can attempt to transmit PDSCH / PUSCH on the time resources of multiple SPS / CG configurations, but can only transmit PDSCH / PUSCH on the time resources of one SPS / CG configuration. When the transmitter is a base station, the base station can attempt to transmit PDSCH or receive PUSCH on the time resources of multiple SPS / CG configurations, but can only transmit PDSCH or receive PUSCH on the time resources of one SPS / CG configuration. When the transmitter is a user equipment, the user equipment can attempt to transmit PUSCH or receive PDSCH on the time resources of multiple SPS / CG configurations, but can only transmit PUSCH or receive PDSCH on the time resources of one SPS / CG configuration.

[0202] More preferably, in a period, the HARQ process number is the same regardless of which SPS / CG configuration the PDSCH / PUSCH is transmitted on. For example, the HARQ process number is calculated according to the first SPS / CG configuration in time.

[0203] More preferably, in a period, the HARQ process number is calculated according to the SPS / CG configuration that the actual transmitted SPS / CG PDSCH / PUSCH occupies.

[0204] More preferably, the base station configures whether the transmitter can transmit PDSCH / PUSCH on multiple or one SPS / CG configuration in a period.

[0205] Another implementation, same as the method described above, only configure a set of general parameters, in which the time characteristic parameters are only applicable to the first set of SPS / CG configuration in the multiple sets of SPS / CG configuration, and the time resources of PDSCH / PUSCH of other SPS / CG configuration are determined by the time resources of PDSCH / PUSCH of the first set or the previous set of SPS / CG configuration and the time offset between the sets of SPS / CG configuration; and additionally configure a time offset between the sets of SPS / CG configuration; without configuring the number of sets of SPS / CG configuration, the number of sets of SPS / CG configuration is determined by the number of SPS / CG PUSCH that can be completely mapped in a period. As shown in FIG. 2, in a period, at intervals of 2 symbols, the maximum number of CG PUSCH that can be completely mapped is 6, and the base station does not need to configure the number of SPS / CG configurations, and the base station and the UE both assume that the number of available SPS / CG configurations is 6. Figure 4

[0206] More preferably, in a period, the sending end can attempt to send PDSCH / PUSCH on the time resources of multiple sets of SPS / CG configuration, but can only send PDSCH / PUSCH on the time resources of one set of SPS / CG configuration. When the sending end is a base station, the base station can attempt to send PDSCH or receive PUSCH on the time resources of multiple sets of SPS / CG configuration, but can only send PDSCH or receive PUSCH on the time resources of one set of SPS / CG configuration. When the sending end is a user equipment, the user equipment can attempt to send PUSCH or receive PDSCH on the time resources of multiple sets of SPS / CG configuration, but can only send PUSCH or receive PDSCH on the time resources of one set of SPS / CG configuration.

[0207] More preferably, in a period, no matter on which time resources of SPS / CG configuration PDSCH / PUSCH is sent, the HARQ process index is the same. For example, the HARQ process number is calculated according to the first set of SPS / CG configuration closest to the time.

[0208] ​More preferably, the HARQ process number is calculated according to the SPS / CG PDSCH / PUSCH actually transmitted in a period, based on the SPS / CG configuration.

[0209] In another implementation, for a set of SPS / CG configurations, a set of common parameters is configured, wherein the time characteristic parameter is only applicable to the first SPS / CG PDSCH / PUSCH candidate transmission position in the set of SPS / CG configurations; and the time offset between each SPS / CG PDSCH / PUSCH candidate transmission position in the set of SPS / CG configurations is configured. That is, the time resource of each SPS / CG PDSCH / PUSCH candidate transmission position in the set of SPS / CG configurations is determined by the time resource of the first or previous SPS / CG PDSCH / PUSCH candidate transmission position in the set of SPS / CG configurations and the time offset between the SPS / CG PDSCH / PUSCH candidate transmission positions.

[0210] More preferably, in a period, the transmitter can attempt to transmit PDSCH / PUSCH in multiple SPS / CG PDSCH / PUSCH candidate transmission positions, but can only transmit PDSCH / PUSCH in one SPS / CG PDSCH / PUSCH candidate transmission position. When the transmitter is a base station, the base station can attempt to transmit PDSCH or receive PUSCH in multiple SPS / CG PDSCH / PUSCH candidate transmission positions, but can only transmit PDSCH or receive PUSCH in one SPS / CG PDSCH / PUSCH candidate transmission position. When the transmitter is a user equipment, the user equipment can attempt to transmit PUSCH or receive PDSCH in multiple SPS / CG PDSCH / PUSCH candidate transmission positions, but can only transmit PUSCH or receive PDSCH in one SPS / CG PDSCH / PUSCH candidate transmission position.

[0211] More preferably, the number of SPS / CG PDSCH / PUSCH candidate transmission positions in a period can be configured by high layer signaling, or determined by the number of SPS / CG PUSCHs that can be completely mapped in a period. For example, Figure 5As shown, assuming the uplink data arrives at symbol #6, the UE can start transmitting CG PUSCH at symbol #7 (4th CG PUSCH candidate transmission location in the same period). In the next period, the UE can start transmitting at the first CG PUSCH candidate transmission location.

[0212] Preferably, the HARQ process index is the same regardless of the SPS / CG candidate transmission location within a period. For example, the HARQ process number is calculated from the start of the earliest SPS / CG candidate transmission location.

[0213] Preferably, the HARQ process number is calculated from the start of the SPS / CG candidate transmission location occupied by the actual transmitted SPS / CG PDSCH / PUSCH within a period.

[0214] It is not difficult to see that the above three implementation manners are configured according to multiple SPS / CG PDSCH / PUSCH configurations, and the last implementation manner treats these SPS / CG PDSCH / PUSCH as one SPS / CG configuration.

[0215] The above-described scheme can also be configured and indicated by physical layer signaling. For example, a set of common parameters including at least frequency domain resource and modulation and coding information is indicated in DCI signaling, the set of common parameters is applicable to all PDSCH / PUSCH of one SPS / CG configuration, the DCI contains time resource indication information applicable to the first SPS / CG candidate transmission location in the SPS / CG configuration, and the DCI contains time offset between each SPS / CG candidate transmission location. The set of time offsets between each SPS / CG candidate transmission location can be standard predefined or high layer configured, and the DCI indicates an element in the set of time offsets between each SPS / CG candidate transmission location. Alternatively, the time offset between each SPS / CG candidate transmission location and the time resource of the first SPS / CG candidate transmission location are jointly encoded, and the DCI indicates one of the combination. The time offset between each SPS / CG candidate transmission location can be indicated separately or share the same time offset.

[0216] For example, a set of common parameters, including at least frequency domain resource and modulation and coding information, are indicated in a DCI, which is applicable to all PDSCH / PUSCH of all sets of SPS / CG configurations, and the DCI contains time resource indication information, which is applicable to the first set of SPS / CG configurations among all sets of SPS / CG configurations, and the DCI contains time offset between all sets of SPS / CG configurations. The set of time offset between all sets of SPS / CG configurations can be predefined in the standard or configured by higher layer, and the DCI indicates one element in the set of time offset between all sets of SPS / CG configurations. Alternatively, the time offset between all sets of SPS / CG configurations and the time resource of the first set of SPS / CG configurations are jointly encoded, and the DCI indicates one in the combination. The time offset of each set of SPS / CG configurations can be indicated separately or share the same time offset.

[0217] Preferably, the time offset of each set of SPS / CG configurations is configured by higher layer signaling only. The time offset of each set of SPS / CG configurations can be configured independently, for example, the time offset relative to the reference slot is configured respectively, or the time offset between each set of SPS / CG configurations is the same, and the base station only configures one common time offset, for example, the downlink slot where the current SPS PDSCH configuration is located is determined according to the common time offset and the time resource of the SPS PDSCH configuration which is earlier in time.

[0218] Preferably, the DCI further comprises periodicity information of the SPS / CG configuration. Preferably, the periodicity information of the SPS / CG configuration is jointly coded with time offset between each SPS / CG configuration candidate transmission position, or jointly coded with time offset between each SPS / CG configuration, the periodicity information and time resource of the first SPS / CG candidate transmission position, and the DCI indicates one of the combinations. Preferably, the periodicity information of the SPS / CG configuration is jointly coded with time offset between each set of SPS / CG configurations, or jointly coded with time offset between each set of SPS / CG configurations, the periodicity information and time resource of the first set of SPS / CG, and the DCI indicates one of the combinations.

[0219] Preferably, the DCI further comprises HARQ-ACK timing information. In the DCI, there is only one HARQ-ACK timing information, and each SPS PDSCH configuration shares the same HARQ-ACK timing, or there are multiple HARQ-ACK timing information in the DCI, and each SPS PDSCH configuration corresponds to one HARQ-ACK timing.

[0220] Preferably, if multiple SPS PDSCH configurations are deactivated by one DCI, the HARQ-ACK feedback of the deactivation DCI is determined according to the HARQ-ACK timing and PUCCH resource indicated in the deactivation DCI. In the deactivation DCI, not only the indication of deactivating the SPS PDSCH configuration is included, but also the HARQ-ACK timing and the PUCCH resource indication bit field.

[0221] More preferably, the DCI is a SPS / CG configuration activation DCI, e.g., for activating an enhanced Type 2 SPS / CG transmission. More preferably, the existing bit field in the activation DCI can be reused to indicate the time offset between the SPS / CG configuration candidates and / or the periodicity of the SPS / CG configuration, e.g., the existing bit field includes a bit field for indicating redundancy version and / or a bit field for indicating HARQ process index. More preferably, the DCI is a special DCI with a different DCI format from the activation DCI.

[0222] More preferably, the existing bit field in the activation DCI can be reused to indicate the time offset between the SPS / CG configuration candidates and / or the periodicity of the SPS / CG configuration, e.g., the existing bit field includes a bit field for indicating redundancy version and / or a bit field for indicating HARQ process index. More preferably, the DCI is a special DCI with a different DCI format from the activation DCI.

[0223] More preferably, the base station can only activate or deactivate the multiple sets of SPS / CG configurations simultaneously. As mentioned above, the number and / or index of the multiple sets of SPS / CG configurations with the common parameters are configured by the base station. More preferably, the index of a predefined one of the multiple sets of SPS / CG configurations is indicated in the activation / deactivation DCI, e.g., the index of the set of SPS / CG configuration with the smallest SPS / CG configuration index value is indicated in the activation / deactivation DCI, so that the index values of the other sets of SPS / CG configurations can be determined. The advantage of this approach is that the DCI design for activating / deactivating the multiple sets of SPS / CG configurations is basically the same as the DCI design for activating / deactivating a single set of SPS / CG configuration, i.e., a set of transmission parameters is indicated in the DCI and the index of a set of SPS / CG configuration is indicated in the DCI. The difference is that the index and transmission parameters of the multiple sets of SPS / CG configurations can be determined from the index and transmission parameters of the indicated set of SPS / CG configuration.

[0224] More preferably, the base station can activate or deactivate part of the multiple sets of SPS / CG configurations simultaneously. For example, in the activation / deactivation DCI, a bit field is included to indicate which SPS / CG configurations in the multiple sets of SPS / CG configurations are activated or deactivated. This bit field can be in the form of a bitmap or a combination of multiple sets of SPS / CG configurations configured by higher layer signaling, and this bit field indicates one of the combinations.

[0225] Embodiment Three

[0226] The configuration signaling of time resources, the starting symbol and the symbol length of SPS / CG PDSCH / PUSCH described above can reuse the starting symbol and the symbol length in the time resource allocation table (e.g. PUSCH-TimeDomainResourceAllocation) configured by the base station for the scheduling-based PDSCH / PUSCH, and the time offset between SPS / CG PDSCH / PUSCH and the offset of the first / first set of SPS / CG PDSCH / PUSCH relative to SFN 0 or the time slot / sub-time slot where the SPS / CG activation signaling is located are separately indicated. The two time offsets can be indicated by independent fields or jointly encoded. In another implementation, the starting symbol and the symbol length of SPS / CG PDSCH / PUSCH, the time offset between SPS / CG PDSCH / PUSCH are jointly encoded to form a new time resource allocation table dedicated to SPS / CG PDSCH / PUSCH. Alternatively, the starting symbol and the symbol length of SPS / CG PDSCH / PUSCH, the time offset between SPS / CG PDSCH / PUSCH, and the offset of the first / first set of SPS / CG PDSCH / PUSCH relative to SFN 0 or the time slot / sub-time slot where the SPS / CG activation signaling is located are jointly encoded to form a new time resource allocation table dedicated to SPS / CG PDSCH / PUSCH. In addition, the periodicity information can also be jointly encoded with the time resource information described above to form a new time resource allocation table. The DCI can indicate the row index of the time resource allocation table. Table 1 shows the information element of the time characteristic parameter configuration for the enhanced second type CG PUSCH transmission. The information element "CG PUSCH time resource allocation" includes at least: the time offset between CG PUSCHs "CG PUSCH time offset" in one CG PUSCH configuration, with the value range of 1 symbol, 2 symbols, 4 symbols and 7 symbols, corresponding to the values 0-3 respectively; the time offset between the first CG PUSCH after activation and the activation signaling "CG PUSCH to activation signaling time offset k2", with the value range of 0-32 slots; the starting symbol and the symbol length of the first CG PUSCH after activation in a slot "starting symbol and length", with the value range of the starting symbol located at the 0th symbol-13th symbol and the symbol length of 1-14 symbols.

[0229] Embodiment Four

[0230] In prior art, one SPS / CG configuration can be deactivated by a specific DCI, for example, DCI format 0_0 or DCI format 1_0 scrambled by CS-RNTI or SPS-RNTI, and the HARQ process index, redundancy version, modulation and coding and frequency domain resource indication bit field in the DCI are set to specific values, indicating deactivation of one SPS / CG configuration.

[0231] In order to save DCI overhead, multiple SPS / CG configurations can be deactivated by one DCI. The base station can configure by higher layer signaling whether the deactivation DCI is processed as deactivating only one SPS / CG configuration or deactivating multiple SPS / CG configurations. If the DCI is processed as deactivating multiple SPS / CG configurations, the DCI contains a bit field for identifying multiple SPS / CG configurations. For example, the bit field indicates whether each SPS / CG configuration is deactivated in the form of bit-map. For another example, the higher layer signaling configures 2 M SPS / CG configuration groups, and the M bits of the bit field correspond to 2 M SPS / CG configuration groups. If the mth SPS / CG configuration group corresponding bit indicates deactivation, where m = 1, 2, … 2 M , each SPS / CG configuration in the mth SPS / CG configuration group is deactivated at the same time.

[0232] More preferably, the bit field can reuse the specific bit field in the DCI to indicate the deactivated SPS / CG configuration. For example, the DCI can be used as fallback mode uplink or downlink data scheduling DCI, such as DCI format 1_0, and also be used as the deactivated DCI. At least one of the time domain resource assignment bit field, frequency hopping flag bit field, transmit power control (TPC) bit field, virtual resource block to physical resource block mapping bit field, HARQ process index bit field, redundancy version bit field, modulation and coding scheme bit field, and frequency domain resource assignment bit field in the fallback mode uplink or downlink data scheduling DCI can be used to indicate the deactivated SPS / CG configuration. At least one of the bit fields in the fallback mode uplink or downlink data scheduling DCI that is not used to indicate the deactivated SPS / CG configuration can be used to verify the deactivated DCI. For example, in order to maintain the error correction capability similar to the deactivated DCI in the prior art, the time domain resource assignment bit field and / or the virtual resource block to physical resource block mapping bit field are used to indicate the deactivated SPS / CG configuration, and the HARQ process index bit field, redundancy version bit field, modulation and coding scheme bit field, and frequency domain resource assignment bit field are set to predefined values to verify the deactivated DCI. For another example, the HARQ process index bit field is used to indicate the deactivated SPS / CG configuration, and in order to maintain the error correction capability similar to the deactivated DCI in the prior art, the time domain resource assignment bit field and / or the virtual resource block to physical resource block mapping bit field, redundancy version bit field, modulation and coding scheme bit field, and frequency domain resource assignment bit field are set to predefined values to verify the deactivated DCI.

[0233] More preferably, if the number of configured deactivated SPS / CG configuration groups exceeds the number of combinations that can be indicated by the bit field A, the bit field A and the bit field B are jointly used to indicate the deactivated SPS / CG configuration combination, and the remaining bits of the bit field B can be used to verify the deactivated DCI. The bit fields A and B are predefined by the standard. For example, assuming M = 4, the base station configures 2 M= 16 SPS / CG configuration groups, each of which can include one or more SPS / CG configurations. 4 bits in the deactivation DCI are needed to indicate the deactivation of one of the 16 SPS / CG configuration groups. If the number of bits N of the HARQ process index bit field is greater than or equal to M, the SPS / CG configuration group is indicated by the HARQ process index bit field. The remaining N-M bits of the HARQ process index bit field can be set to a predefined value for the deactivation DCI check. If the number of bits N of the HARQ process index bit field is less than M, the first M-N bits of the time resource allocation bit field are also used to indicate the deactivated SPS / CG configuration group. The remaining bits of the time resource allocation bit field can be set to a predefined value for the deactivation DCI check. For another example, if the number of bits N of the time resource allocation bit field is greater than or equal to M, the SPS / CG configuration group is indicated by the time resource allocation bit field. If N is less than M, the first M-N bits of the number of bits of the transmit power control bit field are also used to indicate the deactivated SPS / CG configuration group. Preferably, if the total number of bits of the bit field A and the bit field B is still less than M, the bits can be jointly indicated with the bit field C. The bit fields A, B, and C are predefined by the standard. Preferably, if the number of configured activated SPS / CG configuration groups exceeds the number of combinations that can be indicated by the bit field A, the activated SPS / CG configuration groups are indicated jointly by the bit field A and the bit field B, and the remaining bits of the bit field B can be used for the activation DCI check. The bit fields A and B are predefined by the standard.

[0234] Preferably, if one DCI activates at most one SPS / CG configuration, if the number of configured SPS / CG configurations exceeds the number that can be indicated by the bit field A, the activated SPS / CG configuration index is indicated jointly by the bit field A and the bit field B, and the remaining bits of the bit field B can be used for the activation DCI check. The bit fields A and B are predefined by the standard.

[0235] More preferably, if one DCI deactivates at most one SPS / CG configuration, if the number of configured SPS / CG configurations exceeds the number of bit field A can indicate, joint bit field A and bit field B indicate the deactivated SPS / CG configuration index, the remaining bits of bit field B can be used for deactivation DCI check. Bit field A and B are predefined by the standard.

[0236] More preferably, the bit field used for indicating SPS / CG configuration or SPS / CG configuration group in activation and deactivation DCI can be different.

[0237] More preferably, if UE is configured with semi-static HARQ-ACK codebook (also known as Type-1 HARQ-ACK codebook), the HARQ-ACK timing bit field can also be used for indicating the deactivated SPS / CG configuration. For example, according to one implementation, the HARQ-ACK of deactivation DCI occupies the HARQ-ACK position corresponding to the deactivated SPS / CG PDSCH, while the HARQ-ACK position corresponding to the SPS / CG PDSCH is determined by the activation DCI, and does not need to rely on the HARQ-ACK timing in the deactivation DCI. Therefore, the HARQ-ACK timing bit field can be used for indicating the deactivated SPS / CG configuration.

[0238] Embodiment five

[0239] The above described method of activating / deactivating or modifying semi-static scheduling parameters can also be extended to the operation of activating / deactivating or modifying transmission parameters for multiple UEs simultaneously by one DCI. Specifically, the same RNTI and DCI for activating / deactivating or modifying semi-static scheduling parameters are allocated for a group of UEs; the bit position in the DCI is configured for each UE; and the SPS / CG configuration and semi-static scheduling transmission parameters corresponding to each UE are configured respectively.

[0240] More preferably, in the DCI, at least one bit field is used for indicating the common resource information of the above-mentioned multiple UEs, and at least one bit field is used for indicating the specific resource information corresponding to each of the above-mentioned multiple UEs respectively. For example, the common resource information is modulation and coding information, and the specific resource information indicated respectively is time-frequency resource information.

[0241] Preferably, in the DCI, each UE has a bit field of at least X bits to indicate 2 X group transmission parameters, or respectively indicate (2 X -1) group transmission parameters, and a specific value of the X bits, e.g. “0”, is reserved for deactivating the SPS / CG configuration. Preferably, in the DCI, each UE has a bit field of at least M*X bits, where M corresponds to M sets of SPS / CG configurations.

[0242] Embodiment six

[0243] The above described methods of activating / deactivating or modifying the semi-persistent scheduling parameters can introduce new DCI formats, or reuse existing DCI formats. If the new DCI format has the same payload as an existing DCI format, e.g. the DCI for reconfiguring the semi-persistent scheduling parameters has the same payload as the activation DCI, or the same DCI format has different uses, e.g. the same DCI format can be used for activating / deactivating or reconfiguring the semi-persistent scheduling parameters of a single SPS / CG configuration, or for activating / deactivating or reconfiguring the semi-persistent scheduling parameters of multiple SPS / CG configurations, a method is needed to distinguish the different DCI formats or different uses of the same DCI format.

[0244] Preferably, the DCI formats or uses can be distinguished by a specific bit field in the DCI, e.g. a bit field dedicated for distinguishing the DCI formats or uses; or by a specific value of a specific bit field in the DCI, e.g. by setting the HARQ process index and redundancy version indication bit field in the DCI to all 0s to indicate operation on a single SPS / CG configuration, or to all 1s to indicate operation on multiple SPS / CG configurations; or by different RNTIs.

[0245] Preferably, for the same DCI format with different uses, the PDCCH search space and / or the control resource set CORESET are configured separately to distinguish the DCI formats or uses.

[0246] Embodiment seven

[0247] If one DCI can only deactivate one CG PUSCH, the deactivation DCI does not need to feedback HARQ-ACK. Generally, to avoid the UE missing the deactivation DCI and continuing to send CG PUSCH, the base station does not schedule other uplink signals on the CG PUSCH resource immediately after the deactivation DCI, and the base station can determine whether the UE still continues to send CG PUSCH by detecting the signal on the CG PUSCH resource. But when one DCI can deactivate multiple CG PUSCHs, if HARQ-ACK is not fed back, to avoid the UE missing the deactivation DCI and continuing to send CG PUSCH, the base station needs to not schedule other uplink signals on all the deactivated CG PUSCHs, which significantly reduces the transmission efficiency of the system. To improve this problem, the present application proposes that when one DCI can deactivate multiple CG PUSCHs, the UE needs to feed back HARQ-ACK for this DCI. Alternatively, when the base station configures a group of deactivated CG PUSCHs, the base station configures whether the deactivation DCI of the group of CG PUSCHs needs to feed back HARQ-ACK. Alternatively, the base station configures whether the UE needs to feed back HARQ-ACK for the deactivation DCI.

[0248] Preferably, the base station configures the PUCCH resource for the UE to feed back the HARQ-ACK of the DCI deactivating the CG PUSCH. For example, the base station configures one PUCCH resource for the UE to feed back the HARQ-ACK of the deactivation DCI. For another example, the base station configures one PUCCH resource for each CG PUSCH group of the UE to feed back the HARQ-ACK of the deactivation DCI.

[0249] Preferably, the base station configures the timing K1 for the UE to feed back the HARQ-ACK of the DCI deactivating the CG PUSCH.

[0250] Preferably, if the base station configures the UE to feedback HARQ-ACK of the DCI deactivating the CG PUSCH, the deactivation DCI includes HARQ-ACK timing K1 information and / or PUCCH resource information. Preferably, at least one of the time resource allocation bit field, the frequency domain hopping bit field, the transmit power control, the HARQ process index bit field, the redundancy version bit field, the modulation and coding method bit field and the frequency domain resource allocation bit field in the DCI can be used to indicate K1 or PUCCH resource information. For example, in the deactivation DCI, the HARQ process index bit field is used to indicate the deactivation CG PUSCH group information, the redundancy version bit field, the modulation and coding method bit field and the frequency domain resource allocation bit field are used for deactivation DCI check, and the time resource allocation bit field is used to indicate K1 and / or PUCCH resource. For another example, in the deactivation DCI, the HARQ process index bit field is used to indicate the deactivation CG PUSCH group information, the redundancy version bit field, the modulation and coding method bit field and the frequency domain resource allocation bit field are used for deactivation DCI check, and the frequency domain hopping bit field and / or the transmit power control bit field are used to indicate K1 and / or PUCCH resource.

[0251] Preferably, the power control bit field in the deactivation DCI is used for power control of the PUCCH.

[0252] When the UE only feedbacks HARQ-ACK of the deactivation DCI deactivating the CG PUSCH (without other PDSCH or PDCCH HARQ-ACK), the UE determines the PUCCH resource according to the semi-static configuration of the base station or the indication of the DCI. When the HARQ-ACK is feedback together with other HARQ-ACK, the PUCCH resource is determined jointly according to the PUCCH resource indicated by the deactivation DCI and the PUCCH resource of the other HARQ-ACK. For example, the PUCCH resource of the deactivation DCI and other PDSCH HARQ-ACK is determined according to the PUCCH resource indicated by the last DCI feedbacking HARQ-ACK in the same PUCCH.

[0253] When the HARQ-ACK of the deactivation DCI of the CG PUSCH is fed back together with other HARQ-ACKs, the bit position of the HARQ-ACK of the deactivation DCI in the HARQ-ACK codebook needs to be determined. Preferably, if the base station configures the UE with a semi-static HARQ-ACK codebook, the time resource indicated by the time resource allocation bit field in the deactivation DCI belongs to the set of PDSCH time resources that can be indicated by the TDRA of the PDSCH. For example, the time resource allocation bit in the DCI that deactivates the CG PUSCH corresponds to TDRA1 of the downlink PDSCH. The bit position of the HARQ-ACK of this DCI is determined according to the time position of the PDSCH indicated by TDRA1. For another example, the base station configures the deactivation DCI of the CG PUSCH with a PDSCH time resource, and the bit position of the HARQ-ACK of this deactivation DCI is determined according to the configured PDSCH time resource. The UE determines the bit position of the HARQ-ACK of the deactivation DCI in the semi-static codebook according to the indicated time resource position. Preferably, if the base station configures the UE with a dynamic HARQ-ACK codebook, the deactivation DCI contains DL DAI information. The UE determines the bit position of the HARQ-ACK of the deactivation DCI in the dynamic codebook according to the DL DAI. For example, the frequency domain hopping bit field in the deactivation CG PUSCH DCI can be redefined as DL DAI.

[0254] Embodiment Eight

[0255] In order to improve the reliability of the response to the activation / deactivation DCI, the activation / deactivation DCI can be acknowledged by a control information MAC CE of the medium access control layer. For the sake of convenience, this MAC CE is referred to as a CG acknowledgment MAC CE.

[0256] In order to distinguish it from other functional MAC CEs, the function of this MAC CE is determined by the value of the logical channel ID (LCID) in the MAC subheader. For example, when the LCID takes the value 55, it indicates that this MAC CE is a CG acknowledgment MAC CE.

[0257] In one CG confirmation MAC CE or MAC subheader contains an indication of CG PUSCH configuration ID. Preferably, N bits indication is one-to-one corresponding to N CG PUSCH configuration IDs by bitmap. For example, 8 bits bitmap is one-to-one corresponding to 8 configuration IDs. Or, 16 bits bitmap is one-to-one corresponding to 16 configuration IDs. Preferably, the number of bits of CG PUSCH configuration ID indication is determined according to the total number of configured CG PUSCH configurations. For example, if the total number ≤8, 8 bits indication, if 8<total number≤16, 16 bits indication. If the total number is less than the number of bits, the unused bits are reserved bits. Preferably, N bits indication is one-to-one corresponding to N CG PUSCH configuration ID groups by bitmap. For example, the base station configures a group of deactivated CG PUSCH configurations, and the CG PUSCH configuration ID group indicated in the CG confirmation MAC CE of activation / deactivation is one-to-one corresponding to the group of deactivated CG PUSCH configurations configured by the base station. In a specific implementation, the base station can activate one CG PUSCH configuration at a time by one DCI, but the CG confirmation MAC CE for the activation DCI indicates the CG PUSCH configuration ID group containing this CG PUSCH configuration ID. In order to avoid the base station from discovering that the UE missed the activation DCI of one CG PUSCH configuration in this group, it can be defined that the base station can only send multiple DCIs to activate each CG PUSCH configuration in this group at the same time. Preferably, log2(N) bits indication is one-to-one corresponding to N CG PUSCH configuration IDs or ID groups. Then, one CG confirmation MAC CE can only confirm the activation / deactivation of one CG PUSCH configuration ID or one CG PUSCH configuration ID group.

[0258] Preferably, the indication of serving cell ID is included in a CG confirmation MAC CE or a MAC subheader. In some scenarios, it is supported that the activation / deactivation of CG PUSCH on serving cell CCj is confirmed by sending a CG confirmation MAC CE on serving cell CCi. By the indication of serving cell ID in the CG confirmation MAC CE, it can be determined that the CG confirmation MAC CE is the confirmation of the activation / deactivation of CG PUSCH on which serving cell.

[0259] Preferably, the indication of BWP ID is included in a CG confirmation MAC CE or a MAC subheader. In some scenarios, it is supported that the activation / deactivation of CG PUSCH on serving cell BWPj is confirmed by sending a CG confirmation MAC CE on BWPi. By the indication of BWP ID in the CG confirmation MAC CE, it can be determined that the CG confirmation MAC CE is the confirmation of the activation / deactivation of CG PUSCH on which BWP.

[0260] Preferably, when a CG confirmation MAC CE includes information of multiple CG PUSCH configurations, all information related to a CG PUSCH configuration is arranged first, and all information related to the next CG PUSCH configuration is arranged next. Alternatively, information of the same type related to each CG PUSCH configuration is arranged first, and information of another type related to each CG PUSCH configuration is arranged next.

[0261] Preferably, when a CG confirmation MAC CE includes information of multiple CG PUSCH configurations, the multiple CG PUSCH configurations belong to the same serving cell and / or the same BWP. For example, a CG confirmation MAC CE includes 24 bits, the first 8 bits indicate the cell ID and the BWP ID, and the last 16 bits indicate one or more CG PUSCH configuration IDs.

[0262] Preferably, the activation / deactivation indication is included in a MAC CE or a MAC subheader. For example, the R bit in the MAC Subheader takes the value of 1 to represent activation, and takes the value of 0 to represent deactivation.

[0263] More preferably, the CG-ACK MAC CE is empty or contains at least 8 bits, which is indicated by the MAC subheader. For example, in the MAC subheader, 2 bits R and 6 bits LCID are included, wherein at least 1 bit of the 2 bits R can be used to indicate whether the CG-ACK MAC CE is empty. For another example, in the MAC subheader, 1 bit R, 1 bit F and 6 bits LCID are included, wherein the 1 bit F indicates whether the CG-ACK MAC CE is empty.

[0264] The CG-ACK MAC CE is carried by PUSCH. Generally, the CG-ACK MAC CE can be transmitted on the uplink resource for a new transmission when the MAC entity has the uplink resource. If the CG-ACK MAC CE for the activated DCI is sent on the activated CG PUSCH resource, the CG-ACK MAC CE can be determined according to the CG PUSCH resource that the CG-ACK MAC CE is the confirmation of the DCI that activates this CG PUSCH. In this way, when there is no CG PUSCH configuration information in the CG-ACK MAC CE, the base station can also determine the CG PUSCH configuration ID corresponding to the received CG-ACK MAC CE. Similarly, the base station can also determine the cell ID and BWP ID of the CG PUSCH corresponding to the received CG-ACK MAC CE. If the resources of at least two activated CG PUSCHs overlap, the CG-ACK MAC CE for the DCI that activates the second CG PUSCH is sent on the next resource of this CG PUSCH.

[0265] Embodiment Nine

[0266] Supporting Time-Sensitive Communications (TSC) is an important scenario for NR-based industrial Internet of Things. TSC traffic usually arrives according to a fixed period, but the period can not be the period of CG / SPS transmission that the existing 5G system can support. For example, the SPS / CG period supported by the 5G system is in units of symbol length, or in units of time slots, for example, the period is 1 ms, and the time interval between adjacent SPS / CG PDSCH / PUSCH is an integer multiple of 1 ms. But the period of TSC traffic can be 0.8 ms, which cannot be aligned with the SPS / CG period. For another example, the period of TSC traffic is 1.1 ms, and the interval between two adjacent TSC traffic packets cannot even be aligned with the boundary of an OFDM symbol (the time length of an OFDM symbol including CP is about 71.4 microseconds).

[0267] To make the TSC service transmitted by SPS / CG PDSCH / PUSCH as timely as possible, the transmission of SPS / CG PDSCH / PUSCH can be determined by at least one of the following ways:

[0268] (1) According to the configured data arrival time, the nearest data transmission symbol no earlier than the data arrival time is determined, and SPS / CG PDSCH / PUSCH is transmitted from the data transmission symbol.

[0269] Specifically, the configured data arrival time can be realized by a configured period and a relative time offset. For example, the time unit of the configured period is a general time unit such as seconds, milliseconds, microseconds, etc. And the time offset is configured relative to the start of SFN0, or relative to the end position of the slot / sub-slot where the activation DCI is located, or the end position of the last symbol of the activation DCI. The time unit of the time offset is a general time unit such as seconds, milliseconds, microseconds, etc., or the time unit of the time offset is a symbol or a slot. Or the configured data arrival time can be realized by configuring the absolute time of the first data service arrival and the configured period.

[0270] The configured data arrival time is mapped to the frame structure time, for example, a certain data arrival time is located in the X3th symbol of the X2th slot in SFN X1. Then, SPS / CG PDSCH / PUSCH is transmitted from the X4th symbol to carry the data, wherein the symbol length of SPS / CG PDSCH / PUSCH is configured by the base station.

[0271] It is not difficult to see that there may be cases where the time difference between adjacent SPS / CG PDSCH / PUSCH is different. For example, the configured time offset is 2.8 ms after SFN0, and the period is 10.2 ms, and the time length of SPS PDSCH is 2 symbols. As Figure 7As shown, according to the time offset, the starting symbol of the first SPS / CG PDSCH / PUSCH is determined to be symbol #12 in slot #2 in SFN #0 (floor(2.8ms / one system frame length 10ms)) (downward rounding (mod(2.8ms, one system frame length) / one slot length 1ms)) (upward rounding ((mod(2.8ms, one slot length) / one OFDM symbol length)), wherein mod represents a modulo operation. The starting symbol of the second SPS / CG PDSCH / PUSCH is determined to be symbol #0 in slot #3 in SFN #1 (floor((2.8+10.2)ms / one system frame length 10ms)) (downward rounding (mod(13ms, one system frame length) / one slot length 1ms)) (upward rounding (mod(13ms, one slot length) / one OFDM symbol length)). The starting symbol of the third SPS / CG PDSCH / PUSCH is determined to be symbol #3 in slot #3 in SFN #2 (floor((2.8+10.2+10.2)ms / one system frame length 10ms)) (downward rounding ((mod(23.2ms, one system frame length) / one slot length 1ms)) (upward rounding ((mod(23.2ms, one slot length) / one OFDM symbol length)).

[0272] (2) According to the configured data arrival time and the configured SPS / CG transmission period T2 and the time offset, in the SPS / CG PDSCH / PUSCH candidate sending position, the candidate sending position closest to the data arrival time and not earlier than the data arrival time is determined, and the SPS / CG PDSCH / PUSCH is sent in the candidate sending position.

[0273] Specifically, the SPS / CG PDSCH / PUSCH candidate sending position is determined according to the transmission period T2 and the time offset. Preferably, if the data arrival time is located after the starting point of an SPS / CG PDSCH / PUSCH candidate sending position, it is sent in the next nearest candidate sending position.

[0274] For example, the configured data arrival time is 2.8ms after the slot #1 where the activation DCI is located, and the period is 15.2ms. The configured SPS PDSCH period is 10 slots (10ms), the time resource of the SPS PDSCH is 4 slots after the slot #1 where the activation DCI is located, i.e. slot #5, and the starting point in the slot #5 is symbol #0, and the time length of the PDSCH is 6 symbols. As shown in FIG. 2, the starting symbol of the first SPS PDSCH is determined to be symbol #12 in slot #2 in SFN #0 (floor(2.8ms / one system frame length 10ms)) (downward rounding (mod(2.8ms, one system frame length) / one slot length 1ms)) (upward rounding ((mod(2.8ms, one slot length) / one OFDM symbol length)), wherein mod represents a modulo operation. The starting symbol of the second SPS PDSCH is determined to be symbol #0 in slot #3 in SFN #1 (floor((2.8+10.2)ms / one system frame length 10ms)) (downward rounding (mod(13ms, one system frame length) / one slot length 1ms)) (upward rounding (mod(13ms, one slot length) / one OFDM symbol length)). The starting symbol of the third SPS PDSCH is determined to be symbol #3 in slot #3 in SFN #2 (floor((2.8+10.2+10.2)ms / one system frame length 10ms)) (downward rounding ((mod(23.2ms, one system frame length) / one slot length 1ms)) (upward rounding ((mod(23.2ms, one slot length) / one OFDM symbol length)). Figure 8As shown, the first data arrives in the slot #4 of SFN i, thus is transmitted on the SPS PDSCH in the slot #5, the second data arrives in the slot #9 of SFN i+1, later than the SPS PDSCH candidate transmission position in the slot #5 of SFN i, thus is transmitted on the SPS PDSCH in the next SPS PDSCH candidate transmission position, i.e. the slot #5 of SFN i+2.

[0275] (3) According to the configured data arrival time and the configured SPS / CG transmission period T2 and time offset, in the SPS / CG PDSCH / PUSCH candidate transmission resource, the data transmission symbol no earlier than the data arrival time and closest to the data arrival time is determined, and the SPS / CG PDSCH / PUSCH is transmitted from the data transmission symbol to the end symbol of the candidate transmission position where the data transmission symbol is located.

[0276] Specifically, the SPS / CG PDSCH / PUSCH candidate transmission position is determined according to the transmission period T2 and the time offset, and the SPS / CG PDSCH / PUSCH candidate transmission resource is determined according to the time length that the PDSCH / PUSCH can occupy. For example, the period T2 is 1 slot, the time offset is 0, the time length of each PDSCH / PUSCH is 2 symbols, K = 2, then the PDSCH / PUSCH candidate transmission resource in one period (1 slot) is symbols 0-3. Preferably, if the data arrival time falls within the candidate transmission resource, the SPS / CG PDSCH / PUSCH can be transmitted in the candidate transmission resource no earlier than the data arrival time and on the symbol closest to the data arrival time, and the transmission is stopped at the end symbol of the candidate transmission position where the symbol is located. For example, the candidate transmission position of the configured SPS PDSCH is symbol #0-symbol #5 in the slot #5, and the 6 symbols are the candidate transmission resource of the SPS PDSCH. As shown, if the data arrival time is in symbol #1, the SPS PDSCH is transmitted on symbol #2-symbol #5. Since the actually transmitted SPS PDSCH is shorter than the time resource of the configured SPS PDSCH, the transmitting end needs to generate the SPS PDSCH according to the configured MCS (Modulation and Coding Scheme) and TBS (Transmission-block Size), and then perform puncturing operation or rate matching operation according to the resource of the actually transmitted SPS PDSCH. Figure 9

[0277] ​Preferably, if the data arrival time point falls outside the candidate sending resource, the SPS / CG PDSCH / PUSCH is sent in the next nearest candidate sending resource.

[0278] (4) According to the configured data arrival time, the configured SPS / CG transmission period T2 and time offset, and the time window, the PDSCH / PUSCH resource for sending the service is determined. Specifically, according to the configured data arrival time, the time window in which the PDSCH / PUSCH can be sent is determined from the data arrival time as the starting point according to the length of the configured time window. If there is at least one SPS / CG PDSCH / PUSCH candidate sending position determined according to the transmission period T2 and time offset within the time window, the earliest one of the candidate sending positions is selected to send the SPS / CG PDSCH / PUSCH. If there is no SPS / CG PDSCH / PUSCH candidate sending position within the time window, the SPS / CG PDSCH / PUSCH is sent from the nearest data transmission symbol no earlier than the data arrival time as the starting point.

[0279] (5) According to the configured data arrival time, the configured SPS / CG transmission period T2 and time offset, and the time window, the PDSCH / PUSCH resource for sending the service is determined. Specifically, according to the configured data arrival time, the time window in which the PDSCH / PUSCH can be sent is determined from the data arrival time as the starting point according to the length of the configured time window. If there is at least one SPS / CG PDSCH / PUSCH candidate sending resource determined according to the transmission period T2 and time offset within the time window, the earliest one of the candidate sending resources is selected to send the SPS / CG PDSCH / PUSCH. If there is no SPS / CG PDSCH / PUSCH candidate sending position within the time window, the SPS / CG PDSCH / PUSCH is sent from the nearest data transmission symbol no earlier than the data arrival time as the starting point.
