    Abstract: Embodiments of the present application provide a data transmission method. The method includes: sending, by user equipment, uplink data to a base station by using an uplink user equipment relay; and receiving, by the user equipment, downlink data from the base station, or receiving, by the user equipment, downlink data from the base station by using a downlink user equipment relay. Uplink transmission and downlink transmission are separately performed in different transmission paths, so as to reduce impact of a fault of a user equipment relay on a network, and improve network reliability.

    Abstract: A resource allocation method to resolve a problem that a transport block of a typical enhanced voice service (EVS) scenario in an air interface is much smaller than a transport block of a conventional adaptive multi rate (AMR), and use of a resource allocation method in the existing long term evolution (LTE) causes a waste of user spectrum resources such that spectrum utilization in an EVS scenario can be improved. The method includes determining resource allocation information and resource allocation block indication information, where the resource allocation information includes information indicating at least one fractional resource block (FRB) allocated to user equipment, and the resource allocation block indication information indicates that a resource allocation block is the FRB, where a resource occupied by the FRB is less than one RB, and notifying the user equipment of the resource allocation information and the resource allocation block indication information.

    Abstract: This application relates to a discontinuous reception method. In the first time unit, for example, the first symbol, after a hybrid automatic repeat request HARQ feedback occasion of a sidelink HARQ process, a first terminal may start a drx-HARQ-RTT-TimerSL and start a drx-RetransmissionTimerSL when the drx-HARQ-RTT-TimerSL expires. During running of the drx-RetransmissionTimerSL, the first terminal monitors a physical downlink control channel. In this way, sidelink retransmission efficiency can be improved, an increase of a sidelink retransmission delay can be avoided, and sidelink-based applications, such as unmanned driving, automatic driving, assisted driving, intelligent driving, networked driving, intelligent networked driving, and car sharing in the field of artificial intelligence can be better supported.
