Abstract: Embodiments of the present disclosure provide a data transmission method, including: receiving, by a first user equipment (UE), a first message sent by a second UE, where the first message includes indication information that the second UE is capable of acting as a relay UE; and performing, by the first UE, data transmission with a base station via the second UE, where the second UE acts as a relay UE. In embodiments of the present disclosure, when first UE is unable to directly perform data transmission with a base station, the first UE uses second UE as a relay UE according to indication information sent by the second UE that the second UE is capable of acting as a relay UE, and then is unable to perform data transmission via the relay UE. Therefore, a success rate of data transmission can be ensured, and further transmission efficiency can be increased.

Abstract: Embodiments of this application disclose a feedback indication method and a communications apparatus, and relate to the communications field, to unify behavior of a transmitting party and a receiving party. This ensures data transmission performance as far as possible. The method includes: A transmitting node determines a first message. A first field in the first message is set to be null, and the first field is used to indicate a time-frequency resource that carries hybrid automatic repeat request HARQ information. The transmitting node sends the first message to a receiving node. The first message is used to indicate the receiving node to delay feeding back HARQ information corresponding to a first transport block TB, or the first message is used to indicate the receiving node to give up feeding back the HARQ information corresponding to the first TB. The first TB is a transport block scheduled by the first message.
