For the implicit method, the same scrambling method or the same sequence can be used to indicate that the received first information and the second information are interrelated data information and data scheduling indication information.

In another implementation, it may be a sidelink scenario, for example, as shown in Figure 7. This scenario may be one in which the anchor node first UE 701 autonomously allocates resources without gNB coverage. Sidelink network architecture, and the BSC UE 703 assists the first UE 701 in transmitting data to the second UE 702. In Figure 7, the first device is the first UE 701, and the first UE 701 can It is considered that the Legacy UE supports the complete 3GPP protocol stack and can be used as an anchor node for other UEs in the sidelink, that is, the anchor node can independently allocate resources to other UEs; the second device is the second UE 702, which can be a legacy UE that supports the complete 3GPP protocol stack. Legacy UE. Similarly, the BSC UE 703 uses the secondary link signal sent by the first UE 701 to the second UE 702 to perform backscatter transmission. The technical solution in this scenario is basically the same as the technical solution in the above scenario. The main differences are:

If the first information is transmitted by the first UE 701, the first information may be carried through the PSSCH.

If the second information is transmitted by the first UE 701, the data scheduling instruction information of the first information can be carried in the PSSCH as the effective data load of the second information, or can also be carried in the Physical SideLink Control Channel (Physical SideLink Control Channel) , PSCCH), and in order to be able to carry the second information, the PSCCH may be extended.

If the second information is transmitted by the BSC UE 703, the second information can be carried through SCI, MAC CE or preamble sequence.

If the first information is transmitted by the BSC UE 703, the first information can be carried through the PSSCH or other data channels.

Correspondingly, the third information transmitted by the first UE 701 to the BSC UE 703 can be carried through SCI, MAC CE or preamble sequence.

The sidelink scenario shown in Figure 7 is a sidelink network deployment architecture that does not involve base stations at all, and is suitable for home scenarios or personal body area networks. If the second information and the third information are carried based on the SCI in the sidelink, the SCI may be a redesigned new two-stage SCI (two-stage SCI format), which requires the second step (2st) in the existing protocol. -stage) SCI type is expanded; or it is a redesigned one-step SCI, that is, one-stage SCI format, which is not limited here.
