In NR, data channel transmission of Configuration Grant (CG) scheduling and semi-persistent scheduling (SPS) is introduced. Generally referred to as Configuration Grant (CG) scheduling for the uplink and semi-persistent scheduling (SPS) in the downlink.
The Configuration Grant (CG) scheduling means that the gNB activates an uplink grant to the terminal device once, and when the terminal device is not deactivated, the gNB always uses the resource specified by the first uplink grant for uplink transmission, and there are two transmission types (types):
configuration authorization (CG) type 1: configured by Radio Resource Control (RRC) through higher layer signaling, such as a configuration authorization configuration information element (IE ConfiguredGrantConfig). The Configuration Grant (CG) Type 1 does not require Downlink Control Information (DCI) for activation and deactivation.
Configuration authorization (CG) type 2: the activation and deactivation of the uplink authorization-exempt indication is carried out by the DCI, and the needed parameters are configured by a configuration authorization configuration information element (IE configurable GrantConfig), but are used when the DCI is required to be activated.
The Configuration Grant (CG) type 1 and the Configuration Grant (CG) type 2 are distinguished according to an RRC uplink configuration grant (RRC-config uplink grant) field in a configuration grant configuration information element (IE ConfiguredGrantConfig), and if the field is configured, it is the Configuration Grant (CG) type 1, and if the field is not configured, it is the Configuration Grant (CG) type 2.
In downlink SPS scheduling, the SPS configuration field is also used for similar parameters. But only one type of downlink. DCI activation and deactivation is required.
In the NR system, physical Uplink Shared Channel (PUSCH) and Physical Downlink Shared Channel (PDSCH) transmission of aggregated multi-slots (slots) may be performed by an aggregation factor (aggregation factor) of Uplink and Downlink. With multi-slot (slot) transmission, the coverage of a single transmission can be improved.
Multi-slot (slot) transmission and Hybrid Automatic Repeat reQuest (HARQ) are combined to achieve more transmissions, which can achieve greater coverage performance and lower error rate. A diagram of a combination of grant-less HARQ and data multi-slot (slot) transmission may be as shown in fig. 2. In fig. 2, in HARQ process x, after data packet n arrives, for the initial transmission of data packet n, the number of slots for the repeated transmission is 4; for the first retransmission of the data packet n, the number of the time slots for repeated transmission is also 4; for the second retransmission of the data packet n, the number of the time slots for the repeated transmission is also 4; for the third retransmission of the data packet n, the number of the time slots for the repeated transmission is also 4; for the fourth retransmission of packet n, the number of slots for its repeated transmission is also 4. Outside the 50ms boundary of packet n, no further retransmission is made for packet n. In the HARQ process y, after the data packet n +1 arrives, for the initial transmission of the data packet n +1, the number of the repeatedly transmitted time slots is 4; for the first retransmission of the data packet n +1, the number of the time slots for repeated transmission is also 4; for the second retransmission of packet n +1, the number of slots for its repeated transmission is also 4, …. Outside the 50ms boundary of packet n +1, no further retransmission is made for packet n + 1. In HARQ process z, after data packet n +2 arrives, the number of slots for repeated transmission for the initial transmission of data packet n +2 is 4, …. Outside the 50ms boundary of packet n +2, no further retransmissions are made for packet n + 2.
It should be noted that, in the above fig. 2, the retransmission is performed after the transmission fails. Furthermore, the different HARQ processes do not overlap in the time domain.
For the data channels of CG scheduling and SPS scheduling, the transmission repetition value of the data portion thereof is semi-statically configured (as configured by an aggregation factor), and furthermore, the CG scheduling is not dynamically changeable. If a relatively large polymerization factor (aggregation factor) is introduced, the number of repetitions is large. If the self-adaptation is not available, the resource occupation is large. In addition, reconfiguration of aggregation factors (aggregation factors) is long. The persistent scheduling requirements such as VoIP traffic cannot be met.
Based on the above problem, the present application provides a data transmission scheme, where the originating device may determine the number of repeating time units actually transmitted by the data channel under the condition that the number of repeating time units transmitted by the data channel each time is configured at a high level, so as to meet the requirement of persistent scheduling of, for example, voIP services, and improve the spectrum utilization rate of data channel transmission.
The technical solution of the present application is detailed below by specific examples.
Fig. 3 is a schematic flow chart of a method 200 of data transmission according to an embodiment of the present application, and as shown in fig. 3, the method 200 may include at least some of the following:
s210, when the number of the repeated time units of each transmission of the data channel is configured in the higher layer,
and the transmitting terminal equipment determines the number of the repeating time units of the (M + 1) th transmission of the data channel according to the number of the repeating time units of the Mth transmission of the data channel and/or the dynamic signaling, wherein M is a positive integer.
In the embodiment of the present application, for example, the higher layer configures the number of repeating time units per transmission of the data channel by an aggregation factor (aggregation factor). In addition, the number of the repeating time units of each transmission of the data channel is a semi-static parameter configured by a higher layer.
It should be noted that the originating device may be a terminal device, in which case the receiving device may be a network device, and the data channel may be a PUSCH. The originating device may also be a network device, in which case the receiving device may be a terminal device, and the data channel may be a PDSCH. Of course, when the originating device is a terminal device, the receiving device may also be a terminal device, and the data Channel may be a Physical Sidelink Shared Channel (psch).
Optionally, the time unit comprises a slot and/or a symbol. That is, in the embodiment of the present application, the time unit may be a time slot or a symbol. In addition, the time unit may also be some time domain information with other granularities, which is not limited in this application.
Optionally, the data channel is carried by CG resources or alternatively, the data channel is carried by SPS resources.
It should be noted that, in the case that the originating device is a terminal device and the receiving device is a network device, the data channel may be carried by CG resources; in the case where the originating device is a network device and the receiving device is a terminal device, the data channel may be carried by SPS resources.
Optionally, in this embodiment of the present application, the number of the repeating time units of each transmission of the data channel is taken from a first value group, and the first value group includes a discontinuous group of values.
