Configuration grant (CG) scheduling and semi-persistent scheduling (SPS) data channel transmissions are introduced in NR. For uplink, it is generally referred to as Configuration Grant (CG) scheduling, and in downlink, it is generally referred to as Semi-Persistent Scheduling (SPS).

Configuration Grant (CG) scheduling means that the gNB activates an uplink grant to the terminal device. If the terminal device does not receive the deactivation, it will always use the resources specified by the first uplink grant for uplink transmission. There are two types. Transmission type (type):

Configuration Grant (CG) type 1: Configured by Radio Resource Control (RRC) through high-level signaling, such as configuration authorization configuration information element (IE ConfiguredGrantConfig). Configuration Authorization (CG) Type 1 does not require Downlink Control Information (DCI) for activation and deactivation.

Configuration authorization (CG) type 2: The DCI instructs the uplink authorization-free activation and deactivation. The required parameters are configured by the configuration authorization configuration information element (IE ConfiguredGrantConfig), but it is only used when it needs to be activated by the DCI.

Configuration grant (CG) type 1 and configuration grant (CG) type 2 are distinguished according to the RRC uplink configuration grant (rrc-ConfiguredUplinkGrant) field in the configuration grant configuration information element (IE ConfiguredGrantConfig), if this field is configured, it is a configuration grant ( CG)type 1, if this field is not configured, it is configuration authorization (CG)type 2.

In the downlink SPS scheduling, it is also performed according to similar parameters of the SPS configuration field. But there is only one type of downlink. Requires DCI activation and deactivation.

In the NR system, the physical uplink shared channel (PUSCH) and physical downlink shared channel (PDSCH) of multiple slots can be aggregated through the aggregation factor of uplink and downlink. transmission. Through multi-slot (slot) transmission, the coverage of a single transmission can be improved.

Multi-slot (slot) transmission and hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) are combined to achieve more transmissions, which can achieve greater coverage performance and lower bit error rate. A schematic diagram of the combination of license-free HARQ and data multi-slot (slot) transmission may be shown in FIG. 2 . In Figure 2, in HARQ process x, after the arrival of data packet n, for the initial transmission of data packet n, the number of time slots for repeated transmission is 4; for the first retransmission of data packet n, the number of repeated transmissions is 4. The number of timeslots is also 4; for the second retransmission of data packet n, the number of timeslots for repeated transmission is also 4; for the third retransmission of data packet n, the number of timeslots for repeated transmission is also 4 ; For the fourth retransmission of data packet n, the number of time slots for repeated transmission is also 4. Beyond the 50ms boundary of packet n, no retransmissions for packet n are made. In HARQ process y, after the arrival of data packet n+1, for the initial transmission of data packet n+1, the number of time slots for repeated transmission is 4; for the first retransmission of data packet n+1, the repeated transmission is The number of timeslots is also 4; for the second retransmission of data packet n+1, the number of timeslots for repeated transmission is also 4, . . . Beyond the 50ms boundary of packet n+1, no retransmissions for packet n+1 are made. In HARQ process z, after data packet n+2 arrives, for the initial transmission of data packet n+2, the number of time slots for repeated transmission is 4, . . . Beyond the 50ms boundary of packet n+2, no retransmissions for packet n+2 are made.

It should be noted that, in the above-mentioned FIG. 2 , the retransmission is performed only after the transmission fails. Furthermore, different HARQ processes do not overlap in the time domain.

For CG-scheduled and SPS-scheduled data channels, the transmission repetition value of the data part is semi-statically configured (eg, configured by an aggregation factor), and in addition, CG scheduling cannot be dynamically changed. If a larger aggregation factor is introduced, the number of repetitions will be higher. If it cannot be adapted, the resource consumption is large. In addition, reconfiguring the aggregation factor takes a long time. Unable to meet continuous scheduling requirements such as VoIP services.

Based on the above problems, the present application proposes a data transmission scheme. In the case where the number of repetition time units for each transmission of the data channel is configured by a high layer, the originating device can determine the number of repetition time units actually transmitted by the data channel, which satisfies requirements such as VoIP The continuous scheduling requirements of services improve the spectrum utilization of data channel transmission.

Further, the originating device determines the number of repetition time units of the M+1th transmission according to the number of repetition time units of the Mth transmission and the variation of the repetition time unit of the M+1th transmission.

That is, the originating device may jointly determine the number of repetition time units of the M+1th transmission of the data channel according to the number of repetition time units of the Mth transmission of the data channel and the dynamic signaling.

For example, the number of repetition time units of the Mth transmission is 4 time slots, and the variation of the repetition time unit of the M+1th transmission indicated by the dynamic signaling is +2 time slots, then the M+1th transmission The number of repeating time units is 6 time slots.

For another example, the number of repetition time units of the Mth transmission is 4 time slots, and the variation of the repetition time unit of the M+1th transmission indicated by the dynamic signaling is -2 time slots, then the M+1th transmission The number of repeating time units is 2 slots.

Optionally, the variation is in a unit of N, where N is a pre-configured integer value, or N is an integer value configured by a higher layer.

For example, the value of N can be 1, 2, 3, 4, 5, . . . The present application does not limit the specific value of N.

Optionally, the first information field is a reserved information field, or the first information field is a redefined information field.

For example, the first information field occupies 2 bits in the dynamic signaling, and the values "00", "01", "10" and "11" respectively represent: 0, -N, +N, -2N.

Optionally, in other embodiments of the present application, the dynamic signaling is used to indicate the index of the number of repetition time units of the M+1th transmission. Further, the originating device determines the number of repetition time units of the M+1th transmission according to the index of the number of repetition time units and the first correspondence of the M+1th transmission, wherein the first correspondence is the repetition time. The correspondence between the unit number index and the number of repeating time units.

That is, the originating device may determine the number of repetition time units of the M+1th transmission of the data channel according to the dynamic signaling.

Optionally, the first corresponding relationship is pre-configured or agreed in an agreement.

For example, in the first correspondence, the repetition time unit number index 0 corresponds to the repetition time unit number 2, the repetition time unit number index 1 corresponds to the repetition time unit number 4, the repetition time unit number index 2 corresponds to the repetition time unit number 6, and the repetition time unit number index 2 corresponds to the repetition time unit number 6. The time unit number index 3 corresponds to the repeating time unit number 8, the repeating time unit number index 4 corresponds to the repeating time unit number 16, and the repeating time unit number index 5 corresponds to the repeating time unit number 32.

Optionally, in some further embodiments of the present application, the dynamic signaling is used to indicate the number of repetition time units of the M+1th transmission. Further, the originating device determines the number of repetition time units of the M+1th transmission indicated by the dynamic signaling as the number of repetition time units of the M+1th transmission.

Optionally, in some further embodiments of the present application, the originating device determines the number of repetition time units of the M transmissions as the number of repetition time units of the M+1 transmissions.

That is, the originating device may determine the number of repetition time units of the M+1th transmission of the data channel according to the number of repetition time units of the M transmissions.

As an embodiment, as shown in FIG. 4 , the high layer configures that each transmission of the data channel needs to repeat 4 time slots, and the variation indicated by the DCI is in N, and N=2. Specifically, in the HARQ process x, after the arrival of the data packet n, for the initial transmission of the data packet n, the number of time slots for repeated transmission is 4; for the first retransmission of the data packet n, DCI 1 indicates the first time The variation of retransmission relative to the initial transmission is +N, then the number of time slots for repeated transmission in the first retransmission is 6; for the second retransmission of data packet n, DCI 2 indicates that the second retransmission is relative to The variation of the first retransmission is 0, then the number of timeslots for repeated transmission in the second retransmission is also 6; for the third retransmission of data packet n, DCI 3 indicates that the third retransmission is relative to the third retransmission. The variation of the second retransmission is -2N, then the number of timeslots for repeated transmission in the third retransmission is also 2; for the fourth retransmission of the data packet n, DCI 4 indicates that the fourth retransmission is relative to the third retransmission. If the variation of the third retransmission is 0, the number of time slots for repeated transmission in the fourth retransmission is also 2. Beyond the 50ms boundary of packet n, no retransmissions for packet n are made. For the data packet n+1 in the HARQ process y and the data packet n+2 in the HARQ process z, the specific transmission modes refer to the data packet n in the HARQ process x, which will not be repeated here.

It should be noted that, in the above FIG. 4 , retransmission is performed only after transmission fails; different HARQ processes do not overlap in the time domain. In addition, the time slot between two adjacent transmissions can also be flexibly indicated by DCI. For example, DCI 1 can also indicate that the time slot between the initial transmission and the first retransmission is 6, and DCI 2 can also indicate The time slot between the first retransmission and the second retransmission is 8, DCI 3 can also indicate that the time slot between the second retransmission and the third retransmission is 6, and DCI 4 can also indicate The time slot interval between the third retransmission and the fourth retransmission is 10.
