Targeted design; on the other hand, NR includes four types of services, such as Enhanced Mobile Broadband (eMBB), Massive Machine Type Communication (MMTC), and low Ultra Reliable and Low Latency Communication (URLLC), enhanced Multimedia Broadcast/Multicast Service (eMBMS), Quality of Service (QoS) for each service The requirements are different, for example, URLLC is more focused on low latency. Wherein the transmitting unit by using a shorter time granularity to achieve lower delay.

It is also possible to allocate reference resources and data resources or feedback resources by symbols.

Example 10

The scheduling frame SDF is configured as an auto-feedback structure of the uplink data in the scheduling frame, and is used to carry the URLLC (Low-Delay Super-Reliable) service.

In addition, the uplink and downlink sections may be respectively inserted into the uplink and downlink reference signals. For example, the uplink reference signal may be inserted at the end of the uplink symbol, that is, after the uplink data; the downlink reference signal may be inserted before the downlink feedback, thereby reporting that the base station has enough time to receive and decode the uplink. data.

Example 11

The scheduling frame SDF is configured to load balance the uplink and downlink traffic in the SDF range, and the dynamic change of the uplink and downlink traffic demand. There is a need for the uplink and downlink to be switched in the SDF, that is, the SDF includes both uplink data and downlink data. The ratio of the row NRsf can be dynamically configured according to the amount of uplink and downlink data.

Contains two structures: the downlink to uplink switching SDF structure is the same as Figure 9, p=0 or configuration The parameter does not contain p, and the values of m and n can be flexibly configured. The special NRsf can be configured as (3) or (4), and both the uplink and downlink NRsf can contain data.

The uplink to downlink switching SDF structure is shown in Figure 17, m = 0, the values of n and p can be flexibly configured according to the uplink and downlink traffic, the special NRsf selection structure (2), and the uplink and downlink NRsf can contain data.

In addition, this structure is also advantageous for the avoidance of uplink and downlink interference when different services are multiplexed in the same frequency band by FDM, that is, by inserting the structure given in this example on the subband occupied by a certain service, thereby The uplink and downlink NRsf configurations of other services on the neighboring cell are aligned to avoid serious interference caused by the uplink and downlink misalignment.

Example 12

The scheduling frame SDF of the length of one NRsf is configured to be used for load balancing of the uplink and downlink traffic in the SDF range, and the dynamic change of the uplink and downlink traffic demand, and there is a demand for switching between the uplink and the downlink in the SDF, that is, the SDF also includes the uplink. Data and downlink data, the ratio of uplink and downlink NRsf can be dynamically configured according to the amount of uplink and downlink data.

Contains two structures:

The downlink to uplink switching SDF structure is the same as that of FIG. 13, p=0 or the configuration parameter does not include p, and m=n=0, the special NRsf can be configured as (5) or (6), and both uplink and downlink symbols can be included. Data, the ratio of the uplink and downlink symbols can be configured according to the proportion of the amount of uplink and downlink data;

The structure of the uplink-to-downlink handover implemented in the SDF of one NRsf is as shown in FIG. 18, p=0 or the configuration parameter does not include p, and m=n=0, the special NRsf selection structure (8), uplink and downlink Data can be included in the symbol, and the ratio of the uplink and downlink symbols can be configured according to the ratio of the amount of uplink and downlink data.

In addition, this structure is also advantageous for the avoidance of uplink and downlink interference when FDM multiplexing of different services in the same frequency band, that is, by inserting the structure given in this example on the subband occupied by a certain service, thereby The uplink and downlink symbols of other services on the adjacent subbands are aligned to avoid serious interference caused by the uplink and downlink misalignment.

Example 13

In a TDD system, when multiple SDFs are in the same frequency band, FDM, or adjacent frequency coexistence, you need to consider aligning the guard interval configuration. That is, ensure that the uplink and downlink time domain resources of different subbands are consistently configured. Otherwise, serious uplink and downlink interference will occur. . The SDF configuration needs to consider this coexistence requirement. As shown in Figure 19, during this period of time, the SDF configuration of each terminal conforms to the uplink and downlink structure configuration of the functional structure, involving four SDF configurations:

SDF1 is a full downlink SDF for downlink data and or control and or signal transmission;

SDF2 is an uplink data scheduling transmission SDF, including downlink control, GP, and uplink data; the downlink control part is used for authorization of uplink data transmission; optionally, the uplink and downlink reference signals may also be included;

SDF3 is a full uplink SDF for uplink data and or control and or signal transmission;

SDF4, in sub-band 2, occupies the entire functional structure, is a downlink self-contained SDF (including self-contained SDF), including downlink control, downlink data, guard interval GP, and uplink control. The uplink control part includes ACK/NACK feedback for downlink data, and potentially includes channel state information, scheduling request, and the like.

Example 14

When there is an individual guard interval that cannot be aligned, the time domain resource that is inconsistent with the uplink and downlink resources due to the misalignment of the guard interval needs to be punctured.

As shown in FIG. 20, compared with FIG. 19, there are two changes, and SDF5 is configured with a long downlink area. In the sub-band 1 corresponding thereto, SDF1 has a downlink data self-feedback requirement, and a partial symbol is inserted. For the uplink control, the sub-band 2 corresponding symbol needs to be punctured, that is, the SDF5 is idle on the time domain resource corresponding to the uplink part of the SDF1, and the downlink transmission is not allowed. Similarly, the SDF4 is configured as an uplink scheduling transmission SDF, and a partial downlink is inserted. The control symbol is used to send the UL grant. Correspondingly, the uplink symbol corresponding to the SDF5 is also punctured, that is, the SDF5 is idle on the time domain resource corresponding to the downlink part of the SDF4, and the uplink transmission is not allowed.

Example 15

When there is a significant difference between the uplink and downlink ratios of the services multiplexed by the two FDM modes, if the GP alignment is to be implemented, the SDF structure configuration alone is not enough, and there will be waste of resources, for example, the mMTC service is dominant, and the eMBB downlink service accounts for more. A large proportion, at this time, consider Figure 21 Mode processing: Partial downlink NRsf of mMTC is shared to eMBB (Fig. 21 left diagonal dotted frame); that is, in the time corresponding to SDF2, the downlink NRsf of mMTC has no data to be transmitted, so it is shared to eMBB, and eMBB transmits its own downlink. Control and or downlink data and or downlink reference signals.

Example 16

This example provides another way to solve the problem of the mismatch between the uplink and downlink traffic ratios in the two-service FDM. Configure some of the upstream bandwidth of the eMBB to mMTC (the left-hand slash of the left part of Figure 22). The proportion of uplink frequency domain resources is different from that of downlink frequency domain resources.
