Abstract: Embodiments of the present invention provide an access method, a device, and a system, to simplify an RA process and improve system efficiency. The method includes: sending, by a base station in a target cell, first information to UE, where the first information is an uplink grant UL grant message, so that the UE sends information on an uplink UL based on the first information. The embodiments of the present invention are used for access.

Abstract: The present invention discloses a data transmission method of a full-duplex system, a user equipment, and a base station. The UE is allowed to initiate full-duplex transmission, and it is unnecessary for the eNB to initiate full-duplex transmission. Before the initiation, the UE does not need to notify the eNB of buffer and preparation statuses of the UE. That is, the UE does not need to send related signaling to the eNB, thereby alleviating load of an entire LTE communications system, avoiding overload during data transmission, and reducing a transmission delay.

Abstract: Embodiments of this application provide an information transmission method and a communication apparatus that may be applied to a communication system, for example, V2X, LTE-V, MTC, IoT, LTE-M, and M2M, to perform information transmission between terminal devices in a contention-based scheduling mode. The method includes: a first terminal device sends first sidelink control information SCI to a second terminal device, where the first SCI includes information about a first subchannel set, the first subchannel set is an available subchannel set sensed by the first terminal device on a sidelink SL, and the first SCI does not include modulation and coding scheme MCS information. In embodiments of this application, the first SCI does not include the MCS information. This can both reduce signaling overheads of the first terminal device, and improve efficiency of demodulating the first SCI by the second terminal device.

Abstract: The present invention relates to a base station, a small cell, and a control channel configuration method to resolve resource waste caused when an additional physical control channel is used on a backhaul link of a small cell to transmit control information. In a base station provided by an embodiment of the present invention, a transceiver module is configured to receive full-duplex capability support information transmitted by a small cell, where the full-duplex capability support information is used to indicate whether the small cell supports use of a same physical layer resource for simultaneous reception on a backhaul link and transmission on an access link; and a processing module is configured to determine a configuration mode of the backhaul link between the base station and the small cell and the access link of the small cell according to the full-duplex capability support information received by the transceiver module.
