Based on the foregoing embodiments, further, the foregoing technical solution may be applied in various application scenarios, and in an implementation manner, a cellular deployment scenario may be used, for example, as shown in fig. 6, where a first device is a base station (gNB) 601, a second device is a first UE602, and may be a Legacy UE supporting a 3GPP protocol stack, and a third device is a BSCUE603, configured to assist the gNB601 in issuing data information to the first UE 602. In this scenario:

in one embodiment, the first UE602 receives the first information sent by the gNB601 and the BSCUE603 sends the second information, where the first information and the second information are data information and data scheduling indication information associated with each other.

The first information may be carried over a data channel, such as PDSCH.

The second information may be carried by a payload, SCI or preamble; if the effective data load is carried, the data scheduling indication information of the first information is used as the effective data load in the second information; if carried by SCI or preamble, the data scheduling indication of the first information is used as the other indication information part in the second information.

The indication information of the signal transmission parameter of the second information transmitted by the BSC UE603 may be carried through the second information. Alternatively, the second information may be used to indicate the transmission mode of the first information due to the limited second information carrying capacity sent by the BSCUE 603. Each transmission mode corresponds to a set of preset data scheduling parameters of the first information, as shown in table 1.

The third information is information associated with the second information, and the third information is indication information sent by the gNB601 and indicating the BSCUE603 to send the second information.

The data scheduling indication information of the first information in the second information serves as a partial payload in the third information.

The third information may further include indication information of signal transmission parameters of the BSC UE, which is used to indicate that fourth information is sent through the BSC UE603, and indicate the signal transmission parameters of the corresponding BSC UE603 to the first UE602, where the fourth information and the second information may be carried in the same or different signaling messages.

In another embodiment, the first UE602 receives the first information sent by the BSC UE603 and the second information sent by the gNB 601.

The first information may be carried over a data channel or other channel.

The second information may be through MAC CE, DCI, RRC signaling or a preamble sequence;

The indication information of the signal transmission parameter of the first information transmitted by the BSC UE603 may be carried by the second information or may be carried by the first information.

In one embodiment, the first information and the second information may also tell the first UE602 that the received first information and second information are data information and data scheduling indication information associated with each other by associating information in a display or implicit manner.

For the display mode, the ID of the opposite device may be carried in the information, for example: when the second information is sent by the BSCUE603, the second information carries ID information of the gNB 601; when the second information is sent by the gNB601, the second information carries ID information of the BSCUE 603.

For implicit mode, the received first information and second information may be characterized as data information and data scheduling indication information associated with each other by the same scrambling mode or the same sequence.

In another embodiment, a sidelink (sidelink) scenario may be, for example, as shown in fig. 7, where the scenario may be a sidelink network architecture in which the anchor node first UE 701 performs resource allocation autonomously without the gNB coverage, and the BSC UE 703 assists the first UE 701 in data transmission to the second UE 702. In fig. 7, the first device is a first UE 701, where the first UE 701 may be a Legacy UE supporting a complete 3GPP protocol stack, and may be used as an anchor node for other UEs in the sidelink, that is, the anchor node may autonomously allocate resources to other UEs; the second device is a second UE 702 may be a Legacy UE with a supporting full 3GPP protocol stack. Similarly, the BSC UE 703 uses the sidelink signal transmitted from the first UE 701 to the second UE 702 for backscatter transmission. The technical scheme in this scenario is basically the same as that in the above scenario, and the main difference is that:

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 indication information of the first information may be carried in the PSSCH as a payload of the second information, or may be carried in a physical sidelink control channel (Physical SideLink Control Channel, PSCCH), and the PSCCH may be extended so as to be capable of carrying the second information.

If the second information is transmitted by BSCUE 703, the second information may be carried through SCI, MAC CE, or preamble sequence.

If the first information is transmitted by the bscure 703, the first information may be carried over the PSSCH or other data channel.

Accordingly, the third information transmitted to the BSCUE 703 by the first UE 701 may be carried through SCI, MAC CE or preamble sequence.

The sidelink scene shown in fig. 7 is a sidelink network deployment architecture without any participation of base stations, and is suitable for a home scene or a personal body area network. If the second information and the third information are based on SCI bearers in the sidelink, the SCI may be a redesigned new two-step SCI format, and the second step (2 st-stage) SCI type in the existing protocol needs to be extended; or a redesigned one-step SCI, i.e., one-stage SCI format, without limitation.

As can be seen from the technical solutions of the foregoing embodiments, in the embodiments of the present application, in different application scenarios, the second device receives the first information and the second information from the third device and the first device, so that the second device parses the first information according to the second information, thereby more effectively improving the transmission efficiency from the first device to the second device, and improving the overall transmission efficiency of the system.
