Abstract: A method for determining a feedback resource in a sidelink includes a first terminal sending SCI to a second terminal, where the SCI includes indication information. The indication information is used to indicate a first resource or a first resource window to be occupied for sending hybrid automatic repeat request HARQ feedback information by the second terminal, and the first resource window includes a plurality of candidate first resources. The method further includes the first terminal receiving, on the first resource, the HARQ feedback information sent by the second terminal, or monitors, in the first resource window, the HARQ feedback information sent by the second terminal.

Abstract: An uplink transmission method based on a licensed-assisted access (LAA) system, and an apparatus, where the method includes reserving, for a transmission burst transmitted on an unlicensed carrier, at least one single-carrier frequency-division multiple access (SC-FDMA) symbol in a subframe of an uplink transmission burst corresponding to the transmission burst, where in the reserved at least one SC-FDMA symbol, user equipment (UE) accesses a channel using a listen-before-talk (LBT) access mechanism. Hence, a time gap for accessing the channel through LBT can be reserved for another UE in the uplink transmission burst. This improves a probability of successfully accessing the channel by another UE such that a plurality of UEs in an LAA communications system can perform uplink multiplexing.

Abstract: Embodiments of the present disclosure provide examples of D2D resource allocation methods, devices, and systems. One example method includes receiving, by first UE, a first message sent by second UE, where the first message is used to request to allocate a resource to the second UE, the first UE is UE in a network coverage area of a base station, and the second UE is UE out of the network coverage area of the base station. Resource indication information of a first resource allocated to the second UE is obtained by the first UE according to the first message. A second message is sent by the first UE to the second UE, where the second message carries the resource indication information, and the second UE sends data to the first UE by using the first resource according to the resource indication information.

Abstract: A signal transmission method, a signal transmission control method, a user equipment (UE), and a base station, where the signal transmission method includes performing, by UE, channel detection, and sending, by the UE, uplink data when a result of the channel detection is that a channel is available, where the uplink data includes one or more subframes, at least one subframe includes a sounding reference signal (SRS), and the SRS is located at a start location of the subframe. The signal transmission control method includes sending, by a base station, SRS configuration information to the UE radio resource control (RRC) signaling or physical downlink control signaling (DCI) such that the UE sends an SRS based on the SRS configuration information. Hence, utilization of a channel can be significantly improved.

Abstract: A data sending method includes determining, by user equipment, a narrowband time-frequency resource scheduled by a base station. The method further includes performing, by the user equipment, clear channel assessment CCA channel detection on the narrowband time-frequency resource to obtain a channel energy value of the narrowband time-frequency resource. The method further includes determining, by the user equipment, whether the channel energy value is less than a preset energy threshold. When the channel energy value is less than the preset energy threshold, the method includes sending, by the user equipment, uplink data to the base station on the narrowband time-frequency resource.
