Description

Apparatus and method for semi-persistent scheduling

The present disclosure relates to the field of wireless communication technology, and more particularly to a semi-persistent scheduling method, a base station apparatus, and user equipment.

Efforts are being made to develop an improved 5th generation (5G) communication system or a pre-5G communication system in order to meet the increasing demand for wireless data traffic after commercialization of the 4G (4th generation) communication system. For this reason, the 5G communication system or the pre-5G communication system is called a 4G network after (Beyond 4G Network) communication system or an LTE (Long Term Evolution) system after (Post LTE) system.

In order to achieve high data rates, 5G communication systems are being considered for implementation in very high frequency (mmWave) bands (eg, 60 gigabytes (60 GHz) bands). In order to alleviate the path loss of radio waves and increase the propagation distance of radio waves in the ultra-high frequency band, in the 5G communication system, beamforming, massive MIMO, and Full Dimensional MIMO (FD-MIMO) are used. ), array antenna, analog beam-forming, and large scale antenna technologies are being discussed.

In addition, for network improvement of the system, in the 5G communication system, an evolved small cell, an advanced small cell, a cloud radio access network (cloud RAN), an ultra-dense network (ultra-dense network) , Device to Device communication (D2D), wireless backhaul, moving network, cooperative communication, Coordinated Multi-Points (CoMP), and reception interference cancellation Technology development is underway. In addition, in the 5G system, Hybrid Frequency Shift Keying and Quadrature Amplitude Modulation (FQAM) and Sliding Window Superposition Coding (SWSC), which are advanced coding modulation (Advanced Coding Modulation, ACM) methods, and Filter Bank Multi Carrier (FBMC), an advanced access technology, ), Non Orthogonal Multiple Access (NOMA), and Sparse Code Multiple Access (SCMA) are being developed.

The ultra-reliable low-latency communication (URLLC) proposed by 5G presents requirements for both latency and reliability. 3GPP Rel-15 can support an end-to-end latency of less than 1ms and a block error rate of 10-5. With the growth of the Internet of Things, AR and VR, the requirements for URLLC have become more stringent. For example, 3GPP Rel-16 is working on URLLC with higher requirements to support end-to-end latencies of 0.5ms to 1ms and block error rates of 10-6. This presents a challenge for NR communication systems. Currently, a semi-persistent scheduling (SPS)-based transmission scheme for transmission of an NR system is also called a configured grant (CG)-based transmission scheme, and is an important scheme for supporting the URLLC service. In the existing NR system study, the minimum duration of the downlink SPS is 10ms, and it is clearly difficult to meet the latency requirement of 0.5ms~1ms. The minimum duration of an uplink CG transmission may be 2 symbols, but the time resource length (where K is the number of repetitions) that can be used for K consecutive CG transmissions cannot be greater than the CG transmission duration. For example, assuming that the base station configures the period P of CG transmission with 7 symbols and the time length of one PUSCH transmission is 2 symbols, the base station can configure a maximum of K = 3 repetitions, so that The time domain duration is no longer than this period. In addition, uplink CG transmission is also defined as the start position of one CG transmission is related to the RV. For example, a UE may start an uplink transmission only in a transmit chance (TO) where RV is 0. When the RV sequence configured by the base station is {0, 0, 0, 0}, the UE can start transmitting at any TO of the configured CG resource, and the standby latency is small. However, when the RV sequence configured by the base station is {0, 2, 3, 1}, the UE can start transmission only in 3 TO intervals, and the standby latency becomes relatively long. If the period P is large, as shown in FIG. 1 , there is a CG transmission period P=1 slot, the RV sequence is {0, 2, 3, 1}, K=4, and each CG PUSCH has 2 symbols occupy The uplink service arrival time of the UE is the second symbol of the first period, the UE waits until the first TO of the next period to start transmitting, and introduces a latency of 13 symbols, which is a low latency requirement of URLLC cannot satisfy How to improve the existing CG transmission mechanism to support higher low latency requirements is a problem to be solved.

In addition, in the existing NR system, only one SPS configuration/CG configuration is supported, and it is clear that it is difficult to support the URLLC requirements of multiple services. For example, in the Industrial Internet of Things, a terminal may support both a monitoring sensor and a robot arm. These URLLC service characteristics are different, such as latency and traffic requirements. To support multiple services simultaneously, multiple SPS configurations can be introduced to allocate different time-frequency domain resources to each SPS configuration. How to efficiently and flexibly configure and schedule multiple SPS configurations is also a challenge.

Hereinafter, the semi-persistent scheduling method of the above-described embodiment of the present application will be described comprehensively and in detail through the following specific examples.

Specifically, SPS/CG-based transmission may be implemented in at least one of the following schemes. Scheme 1, the base station configures all semi-persistent scheduling parameters using higher layer signaling; After receiving the configuration information of all semi-persistent scheduling parameters, the UE considers that semi-persistent scheduling is activated, and performs reception or transmission of SPS/CG in the corresponding time-frequency resource according to the configuration information; When the base station releases SPS/CG transmission using higher layer signaling, after receiving the SPS/CG release configuration, the UE stops receiving or transmitting SPS/CG in the corresponding time-frequency resource. For convenience of description, this type of SPS/CG transmission is referred to as a first type of SPS/CG transmission. Method 2, the base station configures some of the semi-persistent scheduling parameters using higher layer signaling, and the base station activates SPS/CG transmission through a physical layer control channel such as downlink control information (DCI), indicates the remaining semi-persistent scheduling parameters; After receiving some of the semi-persistent scheduling parameters and the configuration information of the activation DCI, the UE may perform reception or transmission of the SPS/CG in the corresponding time-frequency resource; When the base station deactivates SPS/CG transmission through DCI, after receiving the deactivated DCI, the UE stops receiving or transmitting SPS/CG in the corresponding time-frequency resource. For convenience of description, this type of SPS/CG transmission is referred to as a second type of SPS/CG transmission.

Example 1

In the prior art, in the first type of SPS/CG transmission, when some of the semi-persistent scheduling parameters need to be changed, the base station must transmit higher layer signaling to reallocate all the semi-persistent scheduling parameters. For example, in the case of uplink CG PUSCH transmission, higher layer signaling rrc-Configured Uplink Grant information includes time domain resources, frequency domain resources, antenna port information, reference signal DMRS signals, MIMO related information, modulation and coding information (MCS and TBS), power control, etc. In general, the latency of reconfiguration by higher layer RRC signaling is large. When the first type of SPS/CG transmission needs to feedback a hybrid automatic repeat request acknowledgment (HARQ-ACK), higher layer signaling may also include parameters related to HARQ-ACK feedback, such as HARQ-ACK feedback time information and PUCCH resource information. need to configure them.

In order 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 may be performed by combining the higher layer signaling configuration and DCI dynamic indication. Specifically, 2X sets of semi-persistent scheduling parameters may be configured using higher layer signaling, and one set of semi-persistent scheduling parameters are indicated by X bits in DCI.

Preferably, the higher layer signaling configures a set of parameters to be used after being first activated among the 2X set of semi-persistent scheduling parameters, or the first set of parameters in the configured 2X set of semi-persistent scheduling parameters are activated for the first time It is predefined to be used after the Subsequently, the base station may change the semi-persistent scheduling parameters by DCI dynamically indicating the set of parameters in the 2X set of semi-persistent scheduling parameters. For example, the base station configures a CG configuration and configures 4 sets of semi-persistent scheduling parameters for this CG configuration, where the first set of semi-persistent scheduling parameters are used for first use after activation. After receiving this configuration information, the UE transmits a CG PUSCH according to the first set of semi-persistent scheduling parameters. Subsequently, the base station transmits a DCI indicating that the UE uses a second set of semi-persistent scheduling parameters of the four sets of semi-persistent scheduling parameters. After receiving the DCI, the UE transmits a CG PUSCH according to the second set of semi-persistent scheduling parameters.

Preferably, the semi-persistent scheduling parameter comprises at least one of frequency domain resource information, time domain resource information (eg duration, symbol start and symbol length, time offset, etc.) and modulation and coding information.

Preferably, when the base station configures multiple sets of SPS/CG configurations for the UE and one DCI can simultaneously represent the semi-persistent scheduling parameters of multiple sets of SPS/CG configurations, the SPS/CG configuration indicated in the DCI A number/or index must be configured, and for each set of SPS/CG configuration, there are X bits each representing one set of semi-persistent scheduling parameters among the 2X sets of semi-persistent scheduling parameters. Preferably, X is a predefined or configurable standard, where X can be 0 or other positive integer. When X=0, the number of semi-persistent scheduling parameters is 1. Preferably, the maximum number of SPS/CG configurations that the DCI can represent is a predefined standard, or the maximum payload of the DCI is a predefined standard. For example, the base station configures four sets of SPS configurations in which each index is 0, 1, 2, 3, and four sets of semi-persistent scheduling parameters are configured for each set of SPS configurations. DCI has a total of 8 bits. For each SPS configuration, the values 0-3 of 2 bits correspond to the first to fourth sets of semi-persistent scheduling parameters of the four sets of semi-persistent scheduling parameters. When the SPS configuration is configured for a plurality of carriers, in order to distinguish the SPS configuration for each carrier, different SPS configuration indexes may be allocated, or may be distinguished by carrier information and the SPS configuration index. It should be noted that the number of sets of semi-persistent scheduling parameters configured by the base station for each set of SPS configuration is the same or different. For example, the base station configures two sets of semi-persistent scheduling parameters for a first set of SPS configuration, configures four sets of semi-persistent scheduling parameters for a second set of SPS configuration, and configures a third set of Configure two sets of semi-persistent scheduling parameters for the SPS configuration, and configure four sets of semi-persistent scheduling parameters for the fourth set of SPS configuration.

Preferably, if one DCI can simultaneously represent the semi-persistent scheduling parameters of multiple sets of SPS/CG configurations, the UE transmits the HARQ-ACK feedback after receiving this DCI. In one implementation manner, this DCI indicates PUCCH resources for transmitting HARQ-ACK, such as HARQ-ACK timing and PUCCH time-frequency resources. In another implementation manner, higher layer signaling configures a PUCCH resource for transmitting HARQ-ACK, or higher layer signaling configures a PUCCH resource of HARQ-ACK of each set of SPS/CG configuration, and the UE is in DCI. A PUCCH resource of HARQ-ACK of DCI is determined according to a PUCCH resource of HARQ-ACK of one set of SPS/CG configurations among multiple sets of SPS/CG configurations. Preferably, the PUCCH resource of HARQ-ACK of DCI is determined according to the PUCCH resource of HARQ-ACK in the configuration of the minimum SPS / CG configuration index and / or the minimum index of semi-persistent scheduling parameters of multiple sets of SPS / CG configuration. .

In the prior art, in the SPS/CG transmission of the second type, if it is necessary to change some of the semi-persistent scheduling parameters, the base station may retransmit an active DCI to reconfigure the semi-persistent scheduling parameters, or the base station may use a higher layer Signaling should be sent to reconfigure the semi-persistent scheduling parameters. For example, the active DCI may reconstruct time domain resources, frequency domain resources, antenna port information, reference signal DMRS signals, MIMO related information, modulation and coding information, power control information, and the like. To save physical layer control channel overhead and achieve a balance of flexibility and control channel reliability, the method described above may be used to enable/disable SPS/CG transmission of the second type or to change semi-persistent scheduling parameters.

Preferably, when DCI can simultaneously activate multiple sets of SPS/CG configurations, the number and/or index of SPS/CG configurations indicated in DCI should be configured, and 2X sets of semi-persistent scheduling parameters are set to each SPS/CG configuration. configured for CG configuration, where the X bit represents one set of semi-persistent scheduling parameters of the 2X set of semi-persistent scheduling parameters. In the process of configuring 2X sets of semi-persistent scheduling parameters for each set of SPS/CG configuration, the number of sets of semi-persistent scheduling parameters configured for each set of SPS/CG configuration is the same or different.

Preferably, if the DCI can simultaneously enable/disable multiple sets of SPS/CG configurations, the number and/or index of SPS/CG configurations indicated in this DCI should be configured, and (2X-1) sets of Persistent scheduling parameters are configured for each set of SPS/CG configuration, which respectively correspond to the status values 1 to (2X-1) of the X bits in DCI, and the value “0” of the remaining statuses indicates that the SPS/CG configuration is Indicates that it is disabled. In the process of configuring (2X-1) sets of semi-persistent scheduling parameters for each set of SPS/CG configuration, the number of sets of semi-persistent scheduling parameters configured for each SPS/CG configuration is the same or different.

Preferably, for a set of SPS/CG configuration, the DCI comprises multiple bit fields corresponding to different types of semi-persistent scheduling parameters, each bit field corresponding to one or more sets of semi-persistent scheduling parameters. The semi-persistent scheduling parameters are configured by higher layer signaling, and the set of semi-persistent scheduling parameters is dynamically indicated by corresponding bit fields of DCI. For example, DCI includes two bit fields, one of which is used to indicate frequency domain resources and has an X1 bit, and the base station configures 2X1 frequency domain resource parameters; Another bit field is used to indicate time domain resources and has an X2 bit, and the base station configures 2X2 frequency domain resource parameters.

Example 2

In some scenarios, such as supporting different service types, the parameters of multiple sets of SPS/CG configurations are different. In another scenario, the properties of multiple sets of SPS/CG configurations are similar or identical, in which case a set of signaling may be used to configure the same/common transmission parameters in these SPS/CG configurations. For example, to reduce latency, multiple sets of SPS/CG configurations may be configured for the same URLLC service type. In another example, to solve the problem that the Time Sensitive Service (TSN) period is not an integer multiple of the SPS/CG configuration period, multiple sets of SPS/CG configurations may be configured for the same TSN service. Multiple sets of SPS/CG configurations have the same frequency domain resource, modulation and coding information, duration but different start positions in time domain, for example, time offset between PDSCHs or PUSCHs of multiple sets of SPS/CG configuration this exists The time offset may be in the order of the size of a symbol (eg, in units of OFDM symbols), may be in the order of the size of a slot, subslot, or may be an absolute time equal to X microseconds (an integer multiple of an OFDM symbol). may not be length of time).

In one implementation manner, when configuring multiple sets of SPS/CG configuration, only one set of common parameters such as frequency domain resources, modulation and coding information, periods may be configured, and corresponding time domain resources are each Each is configured for the SPS/CG configuration of the set (e.g., time offset with slots as granularity, and/or symbol starting point and time length (number of symbols) occupied by PDSCH/PUSCH in one slot) .

In another implementation manner, when configuring multiple sets of SPS/CG configurations, only one set of common parameters may be configured, and a time offset between SPS/CG configuration sets may be further configured. Time characteristic parameters in common parameters such as time offset with slot as granularity, start symbol of PDSCH/PUSCH and time length are applied only to the first set of SPS/CG configurations among multiple sets of SPS/CG configurations. can The time domain resources of the PDSCH/PUSCH of different SPS/CG configurations are determined by the time offset between the time domain resources of the first set of SPS/CG configuration or the previous set of SPS/CG configuration and these SPS/CG configuration sets. do.

In addition, the number and/or index of multiple sets of SPS/CGs should be configured.

As shown in FIG. 3 , the base station configures four sets of CG configurations, and uses one set of signaling to indicate frequency domain resources, time domain resources, pilot information (DMRS), MCS, and TBS. The time domain resource information indicates that the period is 1 slot, and indicates the number of slots SFN=0 of the first set of CG configuration time offsets from the system frame, for example 15 time slot time offsets from SFN0, that is, 6 in SFN1. Located in slot No. 1, the time domain resource information indicates that the first set of CG configuration occupies the third to sixth symbols in the slot and the repetition time is K=1. The base station also configures the time offset between the CG configuration sets with two symbols. Then, starting from time slot 15, the 3rd to 6th symbols of each time slot are the resources of the first set of CG constructs (#1 CG in the figure), and the 5th to 8th symbols are the resources of the second set of CG constructs (the figure). in #2 CG), the 7-10th symbols are the resources of the third set of CG configuration (#3 CG in the figure), and the 9-11th symbols are the resources of the fourth set of CG configuration (#4 CG in the figure) ) of the resources.

Preferably, in one period, the transmitting end may attempt to transmit the PDSCH/PUSCH in time domain resources of multiple sets of SPS/CG configurations. The time domain resources of multiple sets of SPS/CG configurations do not overlap each other. For example, the base station configures three sets of SPS PDSCH, frequency domain resources, period, starting point and symbol length of one downlink time unit, pilot information (DMRS), MCS and TBS are the same, and the three sets The time offsets of the SPS PDSCHs of are composed of 0 slots, 16 slots, and 33 slots, respectively. When the base station activates the transmission of three sets of SPS PDSCH configurations, the base station may each transmit the PDSCH on the resources of the three sets of SPS PDSCH configurations.

Preferably, in one period, the transmitting end may attempt to transmit PDSCH/PUSCH in time domain resources of multiple sets of SPS/CG configurations, but only transmit PDSCH/PUSCHs in time domain resources of one set of SPS/CG configurations. can send When the transmitting end is a base station, the base station may try to transmit or receive PUSCH in time domain resources of multiple sets of SPS/CG configurations, but transmit PDSCH only in time domain resources of one set of SPS/CG configurations, or PUSCH can be received. When the transmitting end is user equipment, the user equipment may try to transmit PUSCH or receive PDSCH in time domain resources of multiple sets of SPS/CG configurations, but only transmit PUSCH in time domain resources of one set of SPS/CG. Alternatively, the PDSCH may be received.

Preferably, in one period, the HARQ process number is the same regardless of whether the PDSCH/PUSCH is transmitted in the time domain resources of which SPS/CG configuration. For example, the HARQ process number is calculated according to the earliest SPS/CG configuration set.

Preferably, in one period, the HARQ process number is calculated according to the SPS/CG configuration occupied by the actually transmitted SPS/CG PDSCH/PUSCH.

Preferably, the base station configures the transmitting end to transmit the PDSCH/PUSCH in time domain resources of multiple sets of SPS/CG configurations or one set of SPS/CG configurations in one period.

In another implementation manner, similar to the method described above, only one set of common parameters is configured, wherein the temporal characteristic parameters are applicable only to the SPS/CG configuration of the first set of multiple sets of SPS/CG configurations, All of the time domain resources of the PDSCH/PUSCH of other SPS/CG configurations are determined by the time offset between the time domain resources of the PDSCH/PUSCH of the SPS/CG configuration of the first set or the previous set and the SPS/CG configuration sets and ; Also, a time offset between SPS/CG configuration sets is further configured; The number of SPS/CG configuration sets need not be configured, and the number of SPS/CG configuration sets is determined by the number of SPS/CG PUSCHs that can be fully mapped in one period. 4, in one period, the maximum number of CG PUSCHs that can be fully mapped is 6 in 2 symbol intervals, and the number of SPS/CG configurations does not need to be configured by the base station, and the base station and It is assumed that all UEs have 6 available SPS/CG configurations.

Preferably, in one period, the transmitting end may attempt to transmit PDSCH/PUSCH in time domain resources of multiple sets of SPS/CG configurations, but only transmit PDSCH/PUSCHs in time domain resources of one set of SPS/CG configurations. can send When the transmitting end is a base station, the base station may try to transmit or receive PUSCH in time domain resources of multiple sets of SPS/CG configurations, but transmit PDSCH only in time domain resources of one set of SPS/CG configurations, or PUSCH can be received. When the transmitting end is the user equipment, the user equipment may try to transmit the PUSCH or receive the PDSCH in the time domain resources of multiple sets of SPS/CG configurations, but only transmit the PUSCH in the time domain resources of one set of SPS/CG configurations Alternatively, the PDSCH may be received.

Preferably, in one period, the HARQ process number is the same regardless of which SPS/CG's time domain resources the PDSCH/PUSCH is transmitted in. For example, the HARQ process number is calculated according to the SPS/CG configuration of the earliest set.

Preferably, in one period, the HARQ process number is calculated according to the SPS/CG configuration occupied by the actually transmitted SPS/CG PDSCH/PUSCH.

In another implementation manner, for the set of SPS/CG configuration, a set of common parameters is configured, wherein the temporal characteristic parameters are applicable only to the first SPS/CG PDSCH/PUSCH candidate transmission position in the set of SPS/CG configuration; A time offset between SPS/CG PDSCH/PUSCH candidate transmission positions in the SPS/CG configuration set is configured. That is, the time domain resources of each SPS / CG PDSCH / PUSCH candidate transmission position in the set of SPS / CG configuration are all time domain resources of the first or previous SPS / CG PDSCH / PUSCH candidate transmission position in the SPS / CG configuration set and It is determined by the time offset between the SPS/CG PDSCH/PUSCH candidate transmission positions.

Preferably, in one period, the transmitting end may attempt to transmit the PDSCH/PUSCH in multiple SPS/CG PDSCH/PUSCH candidate transmission positions, but may transmit only in one SPS/CG PDSCH/PUSCH candidate transmission position. . When the transmitting end is a base station, the base station may attempt to transmit or receive a PUSCH at multiple SPS/CG PDSCH/PUSCH candidate transmission positions, but only transmits a PDSCH or transmits a PUSCH at one SPS/CG PDSCH/PUSCH candidate transmission position. can receive When the transmitting end is the user equipment, the user equipment may try to transmit the PUSCH or receive the PDSCH in multiple SPS/CG PDSCH/PUSCH candidate transmission positions, but transmit the PUSCH only in one SPS/CG PDSCH/PUSCH candidate transmission position Alternatively, the PDSCH may be received.

Preferably, the number of SPS/CG PDSCH/PUSCH candidate transmission positions in one period may be configured by higher layer signaling or may be determined by the number of SPS/CG PUSCHs that may be fully mapped in one period. As shown in FIG. 5 , assuming that the uplink traffic arrives at symbol #6, the UE may start CG PUSCH transmission at symbol #7 (the fourth CG PUSCH candidate transmission position in the same period). In the next period, the UE may start transmitting at the first CG PUSCH candidate transmission position.

Preferably, in one period, the HARQ process number is the same regardless of which SPS/CG candidate transmission location's time domain resource the PDSCH/PUSCH is transmitted in. For example, the HARQ process number is calculated according to the earliest SPS/CG candidate transmission position.

Preferably, in one period, the HARQ process number is calculated according to the starting point of the SPS/CG candidate transmission position occupied by the actually transmitted SPS/CG PDSCH/PUSCH.

It is not difficult to understand that the above three implementations are configured according to multiple SPS/CG PDSCH/PUSCH configurations, and the last implementation is handled by considering these SPS/CG PDSCH/PUSCHs as one SPS/CG configuration.

The solution described above may be configured and indicated by physical layer signaling. For example, a common parameter set including at least frequency domain resources and modulation and coding information is indicated in DCI signaling, and the common parameter set may be applied to all PDSCH/PUSCHs of the SPS/CG configuration set, and DCI is the SPS/CG contains time domain resource indication information applicable to the first SPS/CG candidate transmission location in the configuration set, and DCI includes a time offset between SPS/CG configuration candidate transmission locations. The set of time offsets between SPS/CG configuration candidate transmission locations may be a predefined standard or may be configured by a higher layer, and DCI indicates one type of element in the set of time offsets between SPS/CG configuration candidate transmission locations. Alternatively, the time offset between the SPS/CG configuration candidate transmission locations and the time domain resource of the first SPS/CG candidate transmission location are jointly encoded, and the DCI indicates one of these combinations. The time offset between the SPS/CG configuration candidate transmission locations may be indicated separately or may share the same time offset.

For example, a common parameter set including at least frequency domain resources and modulation and coding information is indicated in DCI signaling, and the common parameter set may be applied to all PDSCH/PUSCHs of the SPS/CG configuration of each set, DCI is contains time domain resource indication information applicable to the SPS/CG configuration of the first set of the SPS/CG configuration set, and the DCI includes a time offset between the SPS/CG configuration sets. The set of time offsets between SPS/CG configuration sets may be a predefined standard or configured by a higher layer, and DCI represents one type of element in the set of time offsets between SPS/CG configuration sets. Alternatively, the time offset between the SPS/CG configuration sets and the time domain resource of the first set of SPS/CG configuration are jointly encoded, and DCI indicates one of these combinations. The time offsets between SPS/CG configuration sets may be indicated separately or may share the same time offset.

Preferably, the time offset between SPS/CG configuration sets is configured only by higher layer signaling. Time offsets between SPS/CG configurations may be configured independently, for example, slot time offsets for a reference time slot may be configured respectively, or time offsets between SPS/CG configurations may be the same. The base station configures only the common time offset, for example, the downlink time slot in which the current SPS PDSCH configuration is located is determined based on this common time offset and the time domain resources of the previous SPS PDSCH configuration.

Preferably, the DCI also includes period information of the SPS/CG configuration. Preferably, the duration information of the SPS/CG configuration is encoded dynamically with the time offset between the SPS/CG configuration candidate transmission locations, or the time offset between the SPS/CG configuration candidate transmission locations, the duration information and the first SPS/ The time domain of the CG candidate transmission location is encoded together, and DCI represents one of these combinations. Preferably, the duration information of the SPS/CG configuration is encoded together with the time offset between the SPS/CG configuration sets, or the time offset between the SPS/CG configuration sets, the duration information and the time domain of the first set of SPS/CG. The resource is jointly encoded, and DCI represents one of these combinations.

Preferably, the DCI further includes HARQ-ACK timing information. DCI includes only one HARQ-ACK timing information, and each SPS PDSCH configuration shares the same HARQ-ACK timing. Alternatively, the DCI includes multiple HARQ-ACK timing information, and each SPS PDSCH configuration corresponds to one HARQ-ACK timing each.

Preferably, when multiple SPS PDSCH configurations are simultaneously deactivated through one DCI, the HARQ-ACK feedback of the deactivated DCI is determined according to HARQ-ACK timing and PUCCH resources indicated in the deactivated DCI. The deactivation DCI includes SPS PDSCH configuration deactivation indication as well as HARQ-ACK timing and PUCCH resource indication bit fields.

Advantageously, said DCI is an SPS/CG configuration activation DCI, eg for activating an enhanced second type of SPS/CG transmission. Preferably, the existing bit field is reusable in the active DCI to indicate the time offset between SPS/CG configuration candidate transmission positions and/or duration information of the SPS/CG configuration, for example the existing bit field is a redundancy version It includes a bit field indicating HARQ and/or a bit field indicating HARQ process number. Advantageously, said DCI is a specific DCI and has a DCI format different from the active DCI.

Preferably, an existing bit field is reusable in the active DCI to indicate time offset between SPS/CG configuration sets and/or duration information of an SPS/CG configuration, for example the existing bit field indicates a redundancy version Contains a bit field and/or a bit field indicating the HARQ process number. Preferably, the DCI is a specific DCI and has a DCI format different from the active DCI.

Preferably, the base station can only activate or deactivate multiple sets of SPS/CG configurations simultaneously. As described above, the number and/or index of multiple sets of SPS/CG configurations sharing parameters is configured by the base station. Preferably, the index of the predefined SPS/CG configuration in multiple sets of SPS/CG configurations is indicated in the active/deactivated DCI, for example, the SPS/CG configuration set with the minimum SPS/CG configuration index value is It is indicated in the activation/deactivation DCI, and index values of other SPS/CG configurations may be determined accordingly. The advantage of this method is that a DCI design that simultaneously enables/disables multiple sets of SPS/CG configurations is basically one set of SPS/CG configurations, all representing the transmission parameter set and index of the SPS/CG configuration set in DCI. It is the same as the DCI design to enable/disable. The difference is that the index and transmission parameters of multiple sets of activated/deactivated SPS/CG configurations can be determined simultaneously by indicating the index and transmission parameters of the SPS/CG configuration set.

Preferably, the base station can simultaneously activate or deactivate some of the SPS/CG configurations in multiple sets of SPS/CG configurations. For example, the activation/deactivation DCI includes a bit field indicating which SPS/CG configuration among multiple sets of SPS/CG configurations is activated or deactivated. This bit field may be in the form of a bitmap or may indicate one of the combinations of multiple sets of SPS/CG configurations configured by higher layer signaling.

Example 3

In the above-described time domain resource configuration signaling, the start symbol and symbol length of SPS / CG PDSCH / PUSCH is a time domain resource allocation table configured by the base station for scheduling-based PDSCH / PUSCH configuration (eg, PUSCH-Time Domain It can be reused as a starting symbol and symbol length in Resource Assignment). The time offset between the SPS/CG PDSCH/PUSCH and the time offset of the SPS/CG PDSCH/PUSCH of the first set for SFN 0 or for the slot/subslot in which the SPS/CG activation signaling is located are indicated separately, The two types of time offset may be indicated by independent domains or jointly encoded. In another implementation scheme, the start symbol and symbol length of the SPS/CG PDSCH/PUSCH, and the time offset between the SPS/CG PDSCH/PUSCHs are jointly encoded and dedicated to the SPS/CG PDSCH/PUSCH, a new time domain resource. An allocation table is created. Or, the start symbol and symbol length of the SPS / CG PDSCH / PUSCH, the time offset between the SPS / CG PDSCH / PUSCH, and the first / first for SFN 0 or for the slot / subslot in which the SPS / CG activation signaling is located The time offsets of the SPS/CG PDSCH/PUSCH of the set are jointly encoded to form a new time domain resource allocation table dedicated to the SPS/CG PDSCH/PUSCH. In addition, the period information may be jointly encoded with the above-described time domain resource information to form a new time domain resource allocation table. DCI may indicate a row index of the time domain resource allocation table. Table 1 shows the information elements for the configuration of the time characteristic parameter for the second type of enhanced CG PUSCH transmission. The information element "CG PUSCH time domain resource allocation" is the time offset between CG PUSCHs in the CG PUSCH configuration ("time between CG PUSCHs"), which ranges from 1 symbol, 2 symbols, 4 symbols and 7 symbols corresponding to values 0-3, respectively. offset"); the time offset of the first activated CG PUSCH for activation signaling is "time offset k2 from CG PUSCH to activation signaling", which ranges from 0 to 32 time slots; Symbol starting point and symbol length of the first active CG PUSCH in a time slot, ranging from symbol 0 to symbol 13 and symbol length from 1 to 14 symbols (“Start Symbol and Length”).

Table 1 CG PUSCH Time Domain Resource Allocation Information Elements

Example 4

In the prior art, the SPS/CG configuration may be deactivated by a specific DCI, for example the deactivation of the SPS/CG configuration is indicated by: DCI format 0_0 or DCI scrambled by CS-RNTI or SPS-RNTI Format 1_0 is used, and the HARQ process number, redundancy version, modulation coding and frequency domain resource indication bit fields in the DCI are set to specific values.

To reduce DCI overhead, multiple SPS/CG configurations can be simultaneously activated by one DCI. The base station may deactivate only one SPS/CG configuration or inactivate multiple SPS/CG configurations by configuring the deactivated DCI by higher layer signaling. When one DCI deactivates multiple SPS/CG configurations, the DCI includes a bit field for identifying multiple SPS/CG configurations. For example, this bit field indicates in the form of a bitmap whether to deactivate each SPS/CG configuration. In another example, higher layer signaling constitutes a 2M SPS/CG configuration group, and M bits of the bit field correspond to a 2M SPS/CG configuration group. When the bit corresponding to the mth SPS/CG configuration set indicates deactivation (where m=1, 2, ... 2M), each SPS/CG configuration of the mth SPS/CG configuration group is simultaneously deactivated.

Preferably, the bit field may reuse a specific bit field of DCI to indicate the SPS/CG configuration to be deactivated. For example, the DCI may be used as an uplink data scheduling or downlink data scheduling DCI in a fallback mode such as DCI format 1_0, or may be used as an inactive DCI. Uplink data scheduling or downlink data scheduling in fallback mode Time domain resource allocation bit field in DCI, frequency hopping flag bit field, transmit power control (TPC), virtual resource block to physical resource block mapping (VRB-to-PRB mapping) ) bit field, HARQ process number bit field, redundancy version bit field, modulation coding scheme bit field, or frequency domain resource allocation bit field may be reused to indicate the SPS/CG configuration to be deactivated. At least one bit field in the above bit fields that are not used to indicate to deactivate the SPS/CG configuration may be used to identify a deactivated DCI. For example, to maintain error correction capability similar to the inactive DCI of the prior art, the time domain resource allocation bit field and/or the virtual resource block to physical resource block mapping bit field are used to indicate the SPS/CG configuration to be deactivated, The HARQ process number bit field, the redundancy version bit field, the modulation coding scheme bit field, and the frequency domain resource allocation bit field are set to a predefined value to identify the inactive DCI. In another example, the HARQ process number bit field is used to indicate the SPS/CG configuration to be deactivated, and to maintain error correction capability similar to the prior art deactivated DCI, the time domain resource allocation bit field and/or virtual resource block to physical The resource block mapping bit field, the redundancy version bit field, the modulation coding scheme bit field, and the frequency domain resource allocation bit field are set to a predefined value to identify the inactive DCI.

Preferably, when the number of configured SPS/CG configuration groups to be deactivated exceeds the number of combinations that can be indicated by bit field A, bit field A and bit field B are combined to indicate the SPS/CG configuration group to be deactivated , the remaining bits of bit field B may be used to confirm inactive DCI. Bit fields A and B are predefined by the standard. For example, assume M=4, the base station configures 2M = 16 SPS/CG configuration groups, each SPS/CG configuration group may include one or more SPS/CG configurations, and 4 bits in inactive DCI is required to indicate to disable one of the 16 SPS/CG configuration groups. When the number of bits N of the HARQ process number bit field is M or greater, the SPS/CG configuration groups are indicated by the HARQ process number bit field, and the remaining NM bits of the HARQ process number bit field have a predefined value to identify an inactive DCI. can be set to When the number of bits N of the HARQ process number bit field is less than M, the first MN bit of the time domain resource allocation bit field is also used to indicate the SPS/CG configuration group to be deactivated, and the remaining bits of the time domain resource allocation bit field are deactivated DCI may be set to a predefined value to confirm In another example, when the number of bits N of the time domain resource allocation bit field is greater than or equal to M, the SPS/CG configuration groups are indicated by the time domain resource allocation bit field. If N is less than M, the first M-N bits of the transmit power control bit field are also used to indicate the SPS/CG configuration group to be deactivated. Preferably, if the total number of bits in bit field A and bit field B is still less than M, bit field C may be combined with bit field A and bit field B to indicate the SPS/CG configuration group to be deactivated. Bit fields A, B and C are predefined by the standard. Preferably, when the number of configured SPS/CG configuration groups to be activated exceeds the number of combinations that can be indicated by bit field A, bit field A and bit field B are combined to indicate the SPS/CG configuration group to be deactivated and the remaining bits of bit field B may be used to confirm active DCI. Bit fields A and B are predefined by the standard.

Preferably, one DCI activates at most one SPS/CG configuration, and bit field A and bit field B if the number of configured SPS/CG configurations exceeds the number of combinations that may be indicated by bit field A. indicates the index of the SPS/CG configuration to be combined and activated, and the remaining bits of the bit field B may be used to confirm the activated DCI. Bit fields A and B are predefined by the standard.

Preferably, one DCI disables at most one SPS/CG configuration, and bit field A and bit field B if the number of configured SPS/CG configurations exceeds the number of combinations that may be indicated by bit field A. is combined to indicate the index of the SPS/CG configuration to be deactivated, and the remaining bits of the bit field B may be used to confirm the deactivated DCI. Bit fields A and B are predefined by the standard.

Preferably, the bit fields of activation and deactivation DCI for indicating SPS/CG configuration or SPS/CG configuration group may be different.

Preferably, when the UE is configured with a semi-persistent HARQ-ACK codebook (also referred to as a Type-1 HARQ-ACK codebook), the HARQ-ACK timing bit field may also be used to indicate the SPS/CG configuration to be deactivated. For example, in one implementation, since the HARQ-ACK of the inactive DCI occupies the HARQ-ACK position corresponding to the SPS/CG PDSCH to be deactivated, the HARQ-ACK position corresponding to the SPS/CG PDSCH is determined by the active DCI and there is no need to depend on HARQ-ACK timing in inactive DCI. Accordingly, the HARQ-ACK timing bit field may be used to indicate the SPS/CG configuration to be deactivated.

Example 5

The above-described method of activating/deactivating or modifying semi-persistent scheduling parameters may also be adapted to the operation of simultaneously activating/deactivating or modifying transmission parameters for multiple UEs by one DCI. Specifically, the same RNTI and DCI for performing activation/deactivation or modification of semi-persistent scheduling parameters are assigned to a UE group; Bit positions of each UE in DCI are configured; SPS/CG configuration and semi-persistent scheduling transmission parameters corresponding to each UE are configured.

Preferably, in the DCI, there is at least one bit field used to indicate common resource information of a plurality of UEs, and a bit field used to indicate specific resource information corresponding to each of the plurality of UEs is included. At least one exists. For example, common resource information is modulation and coding information, and specific resource information displayed individually is time-frequency resource information.

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

Example 6

The method of activating/deactivating or modifying the aforementioned semi-persistent scheduling parameters may introduce a new DCI format or reuse an existing DCI format. When the new DCI format has the same payload as the existing DCI format, for example, the DCI used to reconfigure the semi-persistent scheduling parameters has the same payload as the active DCI or the same DCI format has different uses, for example For example, the same DCI format may be used as activation/deactivation or semi-persistent scheduling parameter reconfiguration for one SPS/CG configuration, or may be used as activation/deactivation or semi-persistent scheduling parameter reconfiguration for multiple SPS/CG configurations, Therefore, there is a need for a method for distinguishing between different DCI formats or for different uses of the same DCI format.

Preferably, DCI formats or uses can be distinguished by a specific bit field of DCI, for example a dedicated bit field for distinguishing DCI formats or uses; Alternatively, DCI formats or uses may be distinguished by a specific value of a specific bit field of DCI, for example, by setting both the HARQ process number and redundancy version indication bit fields of DCI to 0 for one SPS/CG indicate operation, and can be distinguished by indicating operation for multiple SPS/CGs by setting both the HARQ process number and redundancy version indication bit fields of DCI to 1; Alternatively, DCI formats or uses may be distinguished by different RNTIs.

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

Example 7

When one DCI can inactivate only one CG PUSCH, the deactivated DCI does not need to feed back HARQ-ACK. In general, the base station continues to transmit CG PUSCH to prevent the UE from not detecting the inactive DCI, the base station does not schedule other uplink transmissions in the CG PUSCH resource immediately after the inactive DCI, and the base station determines that the UE It is determined whether or not to continue to transmit the CG PUSCH by detecting the signal for the resource. However, if one DCI can deactivate multiple CG PUSCHs, if the HARQ-ACK is not fed back, the base station continues to transmit the CG PUSCH to prevent the UE from not detecting the deactivated DCI, and the base station receives all deactivated DCIs. There is no need to schedule other uplink signals in the CG PUSCH, which greatly reduces system transmission efficiency. To improve this problem, the present invention proposes that when one DCI can deactivate multiple CG PUSCHs, the UE needs to feed back HARQ-ACK for this DCI. Alternatively, when configuring the CG PUSCH group to be deactivated, the base station also configures whether the deactivated DCI of the CG PUSCH group should feed back HARQ-ACK. Alternatively, the base station configures whether the UE should feed back HARQ-ACK for deactivation DCI.

Preferably, the base station configures a PUCCH resource for feeding back the HARQ-ACK of the DCI for deactivating the CG PUSCH, for the UE. For example, the base station configures a PUCCH resource for feeding back the HARQ-ACK of the inactive DCI for the UE. In another example, the base station configures one PUCCH resource for feeding back HARQ-ACK of inactive DCI for each CG PUSCH group of the UE.

Preferably, the base station configures, for the UE, timing K1 for feeding back HARQ-ACK of DCI for deactivating CG PUSCH.

Preferably, when the base station configures the UE to feed back HARQ-ACK of DCI for CG PUSCH deactivation, the deactivation DCI includes HARQ-ACK timing K1 information and/or PUCCH resource information. Preferably, at least one of a time domain resource allocation bit field in DCI, a frequency hopping flag bit field, a transmit power control, a HARQ process number bit field, a redundancy version bit field, a modulation coding scheme bit field, and a frequency domain resource allocation bit A bit field may be used to indicate timing K1 or PUCCH resource information. For example, in deactivation DCI, the HARQ process number bit field is used to indicate information for CG PUSCH group deactivation, and the redundancy version bit field, modulation coding scheme bit field, and frequency domain resource allocation bit field are used to identify deactivation DCI The time domain resource allocation bit field is used to indicate the timing K1 and/or PUCCH resource. In another example, in the deactivation DCI, the HARQ process number bit field is used to indicate information for CG PUSCH group deactivation, and the redundancy version bit field, the modulation coding scheme bit field, and the frequency domain resource allocation bit field confirm the deactivation DCI The frequency hopping flag bit field and/or the transmit power control bit field are used to indicate the timing K1 and/or the PUCCH resource.

Preferably, the power control bit field of the inactive DCI is used for power control of the PUCCH.

When the UE feeds back only the HARQ-ACK of the inactive DCI for deactivating the CG PUSCH (not fed back together with the HARQ-ACK of other PDSCHs or PDCCHs), the UE determines the PUCCH resource according to the semi-static configuration of the base station or DCI indication do. When the HARQ-ACK is fed back together with other HARQ-ACKs, the PUCCH resources are jointly determined according to the PUCCH resource indicated by the inactive DCI and the PUCCH resources of the other HARQ-ACKs. For example, PUCCH resources for feeding back HARQ-ACK of inactive DCI and other PDSCHs are determined according to PUCCH resource for feeding back HARQ-ACK indicated by the last DCI in the same PUCCH.

When the HARQ-ACK of the inactive DCI for deactivating the CG PUSCH is fed back together with other HARQ-ACKs, it is necessary to determine the bit position of the HARQ-ACK of the inactive DCI in the HARQ-ACK codebook. Preferably, when the base station configures the semi-static HARQ-ACK codebook for the UE, the time domain resource indicated by the time domain resource allocation bit field in the inactive DCI is the PDSCH time resource that may be indicated by the TDRA of the PDSCH. belong to the set For example, in DCI for CG PUSCH deactivation, TDRA1 corresponding to the time domain resource allocation bit is the TDRA 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. In another example, the base station configures a PDSCH time resource for DCI for deactivating the CG PUSCH, and the bit position of the HARQ-ACK of the deactivation DCI is determined according to the configured PDSCH time resource. The UE determines the bit position of the HARQ-ACK of the inactive DCI in the semi-static codebook according to the indicated time resource position. Preferably, when the base station configures the dynamic HARQ-ACK codebook for the UE, the deactivation DCI includes downlink assignment index (DL DAI) information. The UE determines the bit position of the HARQ-ACK of the deactivated DCI in the dynamic codebook according to the DL DAI. For example, the frequency hopping flag bit field in DCI for deactivating CG PUSCH may be redefined as DL DAI.

Example 8

In order to improve the reliability of the response to the activation/deactivation DCI, the activation/deactivation DCI may be confirmed by the control information MAC CE of the medium access control layer. For convenience of description, this MAC CE is referred to as a CG acknowledgment MAC CE.

To distinguish it from MAC CEs of other functions, the function of this MAC CE is determined by the LCID (Logical Channel ID) value in the MAC subheader. For example, if the LCID value is 55, it is indicated that this MAC CE is a CG Acknowledgment MAC CE.

The indication of the CG PUSCH configuration ID is included in the CG Acknowledgment MAC CE or MAC subheader. Preferably, the indication of N bits corresponds one-to-one with N CG PUSCH configuration IDs in the form of a bitmap. For example, an 8-bit bitmap corresponds to 8 configuration IDs one-to-one. Correspondingly, a bitmap of 16 bits is used for one-to-one correspondence of 16 configuration IDs. Preferably, the number of bits of the CG PUSCH configuration ID indication is determined according to the total number of configured CG PUSCH configurations. For example, if the total number of configured CG PUSCH configurations is less than or equal to 8, 8 bits are used for the indication; If the total number of configured CG PUSCH configurations is greater than 8 and less than 16, 16 bits are used for the indication. If the total number of configured CG PUSCH configurations is less than the number of bits, unused bits are used as reserved bits. Preferably, the indication of N bits corresponds one-to-one with the N CG PUSCH configuration ID group in the form of a bitmap. For example, the base station configures a CG PUSCH configuration ID group to be deactivated, and the CG PUSCH configuration ID group displayed in the CG Acknowledgment MAC CE for activation/deactivation corresponds to the CG PUSCH configuration ID group to be deactivated configured by the base station one-to-one. . In a specific implementation, the base station may activate one CG PUSCH configuration through one DCI each time, but the CG Acknowledgment MAC CE indication for the active DCI includes a CG PUSCH configuration ID group of CG PUSCH configuration IDs. In order to prevent the UE from not detecting the activation DCI of one CG PUSCH configuration in the group that the base station cannot discover, the base station may be configured to transmit multiple DCIs simultaneously and each DCI activates each CG PUSCH configuration in the group do. Preferably, the indication of log2(N) bits corresponds one-to-one with N CG PUSCH configuration IDs or ID groups. Then, the CG acknowledgment MAC CE may acknowledge only the activation/deactivation of the CG PUSCH configuration ID or the CG PUSCH configuration ID group.

Preferably, the indication of the serving cell ID is included in the CG acknowledgment MAC CE or MAC subheader. In some scenarios, it is supported that the CG acknowledgment MAC CE is transmitted in one serving cell CCi to acknowledge activation/deactivation of the CG PUSCH in the serving cell CCj. By the serving cell ID indicated on the CG acknowledgment MAC CE, it may be determined in which serving cell the CG acknowledgment MAC CE is an acknowledgment for activation/deactivation of the CG PUSCH.

Preferably, the indication of the BWP ID is included in the CG Acknowledgment MAC CE or MAC subheader. In some scenarios, it is supported that the CG Acknowledgment MAC CE is transmitted over one BWPi to acknowledge activation/deactivation of the CG PUSCH in the serving cell BWPj. By the BWP ID displayed on the CG acknowledgment MAC CE, it may be determined in which BWP the CG acknowledgment MAC CE is an acknowledgment for activation/deactivation of CG PUSCH.

Preferably, when the CG acknowledgment MAC CE includes information about multiple CG PUSCH configurations, all information related to one CG PUSCH configuration is first sorted, and then all information related to the next CG PUSCH configuration is sorted. . Alternatively, information types for each CG PUSCH configuration are sorted first, and then other information types for each CG PUSCH configuration are sorted.

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

Preferably, the MAC CE includes an activation/deactivation indication, or the MAC subheader includes an activation/deactivation indication. For example, an R bit value of 1 in the MAC subheader indicates activation, and 0 indicates deactivation.

Preferably, the CG Acknowledgment MAC CE is empty, or the CG Acknowledgment MAC CE contains at least 8 bits indicated by the MAC subheader. For example, the MAC subheader includes 2 bits of R and 6 bits of LCID, where at least 1 bit of 2 bits of R may be used to indicate whether the CG acknowledgment MAC CE is empty. In another example, the MAC subheader includes 1-bit R, 1-bit F, and 6-bit LCID, where 1-bit F indicates whether the CG acknowledgment MAC CE is empty.

CG Acknowledgment MAC CE is delivered through PUSCH. In general, if the MAC entity has an uplink resource for new transmission, the CG acknowledgment MAC CE may be transmitted via this uplink resource. When the CG acknowledgment MAC CE for activation DCI is transmitted through the activated CG PUSCH resource, it may be determined from the CG PUSCH resource that the CG acknowledgment MAC CE is an acknowledgment for the DCI for activating this CG PUSCH. In this way, if there is no CG PUSCH configuration information in the CG acknowledgment MAC CE, the base station may also determine the CG PUSCH configuration ID corresponding to the received CG acknowledgment MAC CE. Similarly, the base station may determine the cell ID and the BWP ID in which the CG PUSCH corresponding to the received CG acknowledgment MAC CE is located. If the resources of at least two activated CG PUSCHs overlap, the CG acknowledgment MAC CE for DCI for activating the second CG PUSCH is delayed to be transmitted in the next resource of this CG PUSCH.

Example 9

Time-sensitive communications (TSC) support is an important scenario for NR-based industrial IoT. TSC service generally arrives at a fixed period, but this period may not be the CG/SPS transmission period supported by the existing 5G system. For example, the SPS/CG period supported by the 5G system is a symbol length unit or a time slot unit, for example, a 1 ms period, and a time interval between adjacent SPS/CG PDSCHs/PUSCHs is an integer multiple of 1 ms. However, the duration of the TSC service may be 0.8 ms and may not coincide with the SPS/CG duration. In another example, the duration of the TSC service is 1.1 ms, and the interval between two adjacent TSC service packets is one OFDM symbol boundary (the length of time of one OFDM symbol including a cyclic prefix (CP) is about 71.4 microseconds) and may not match.

In order to enable the TSC service to be transmitted on the SPS/CG PDSCH/PUSCH as timely as possible, the transmission of the SPS/CG PDSCH/PUSCH may be determined by at least one of the following methods:

(1) According to the configured data arrival time, the latest data transmission symbol not earlier than the data arrival time is determined, and the SPS/CG PDSCH/PUSCH is transmitted starting from this data transmission symbol.

Specifically, the configured data arrival time may be implemented by a configuration period and a relative time offset. For example, the configured period is in units of seconds, milliseconds, or microseconds, and other common units of time. Also the time offset to the starting point of SFN0, or the end position of the slot/subslot with the active DCI, or the end position of the last symbol of the active DCI. The time offset is in units of seconds, milliseconds or microseconds and other common units of time, or the time offset is in units of symbols or time slots. Alternatively, the configured data arrival time may be implemented by the absolute time that the first data service arrives and the configured duration.

The configured data arrival time corresponds to the frame structure time, for example, the specific data arrival time is located in the X3th symbol of the time slot X2 in the SFN X1. Then, the SPS/CG PDSCH/PUSCH is transmitted in the X4th symbol carrying data, where the symbol length of the SPS/CG PDSCH/PUSCH is configured by the base station.

It is not difficult to understand that there may be cases where the time difference between adjacent SPS/CG PDSCH/PUSCHs is different. For example, the configured time offset is 2.8 ms after SFN0, the duration is 10.2 ms, and the time length of the SPS PDSCH is 2 symbols. As shown in FIG. 7, the start symbol for transmitting the first SPS/CG PDSCH/PUSCH is a slot of symbol #12 (SFN#0 (rounded down (2.8ms/one system frame length 10ms)) according to the time offset. Determined to be #2 (rounding down (mod(2.8ms, one system frame length)/one slot length 1ms) to rounding ((mod(2.8ms, one slot length)/one OFDM symbol length))) Here, mod denotes a modulo operation. The start symbol for transmission of the second SPS/CG PDSCH/PUSCH is symbol #0 (SFN#1 (rounded down ((2.8+10.2)ms/one system) Rounding ((mod(13ms, one slot length)/one OFDM symbol length) of slot #3 (rounding down (mod(13ms, one system frame length)/one slot length 1ms)) of frame length 10ms)) )) The start symbol for transmission of the third SPS/CG PDSCH/PUSCH is slot # 3 (rounding down (23.2 ms, one system frame length) / one slot length 1 ms) rounding (mod (23.2 ms, one slot length) / one OFDM symbol length)).

(2) at the SPS/CG PDSCH/PUSCH candidate transmission position, the candidate transmission position that is not earlier than the data arrival time and is closest to the data arrival time is determined according to the configured data arrival time, the configured SPS/CG transmission period T2 and the time offset, SPS /CG PDSCH/PUSCH is transmitted at the candidate transmission position.

Specifically, the SPS/CG PDSCH/PUSCH candidate transmission position is determined according to the transmission period T2 and the time offset. Preferably, if the data arrival time is after the starting point of one SPS/CG PDSCH/PUSCH candidate transmission position, it is transmitted at the next closest candidate transmission position.

For example, the configured data arrival time is 2.8 ms after slot #1 with active DCI, and the duration is 15.2 ms. The configured SPS PDSCH period is 10 slots (10 ms), the SPS PDSCH time domain resource is 4 slots (ie, slot #5) after slot #1 where the active DCI is located, and the starting point is symbol #0 in slot #, and the The length of time is 6 symbols. As shown in FIG. 8 , the first data arrives at slot #4 of SFN i and is thus transmitted through the SPS PDSCH of slot #5, and the second data then arrives at slot #9 of SFN i+1, which is It is later than the SPS PDSCH candidate transmission position in slot #5 of SFN I, and therefore is transmitted through the SPS PDSCH in the next SPS PDSCH candidate transmission position, that is, slot #5 of SFN i+2.

(3) in the SPS/CG PDSCH/PUSCH candidate transmission resources, the data transmission symbol that is not earlier than the data arrival time and is closest to the data arrival time is determined according to the configured data arrival time, the configured SPS/CG transmission period T2 and the time offset, , SPS/CG PDSCH/PUSCH are transmitted through symbols starting from a data transmission symbol to the end symbol of a candidate transmission position in which the data transmission symbol is located.

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 length of time during which the PDSCH/PUSCH can be occupied. For example, period T2 is 1 slot, time offset is 0, time length of each PDSCH/PUSCH is 2 symbols, K=2, then PDSCH/PUSCH candidate transmission resource in one period (1 slot) is symbol 0~3.
