Abstract: The present invention discloses a method and an apparatus for selecting a relay in D2D communication. The method includes: determining, by a relay selection device, link quality of a first link of each candidate relay UE in a candidate relay UE list, where the candidate relay UE list includes at least one candidate relay UE, and the first link of each candidate relay UE is a radio link between each candidate relay UE and a base station; and determining target relay UE from the candidate relay UE list according to the link quality of the first link of each candidate relay UE in the candidate relay UE list, where the target relay UE is used for relaying data transmitted between first UE and the base station.

Abstract: Embodiments of the present disclosure provide timing advance (TA) obtaining methods and apparatuses. One example method includes generating, by a base station, an indication message and sending the indication message to UE, and receiving, by the UE, the indication message sent by the base station. The UE can then obtain a TA of a second carrier based on the indication message, where the second carrier is a carrier not used to transmit a PUSCH. Although the second carrier is a carrier not used to transmit a PUSCH, the TA of the second carrier can still be obtained.

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: Methods and devices for transmitting a physical uplink shared channel (PUSCH) in a licensed-assisted access using Long Term Evolution (LAA-LTE) system are provided. One example method performed by a terminal includes: determining that a first unlicensed carrier is unavailable in a subframe n+k, and sending the PUSCH to a base station in the subframe n+k by using an alternate carrier or in one of a subframe n+k+1 to a subframe n+k+m by using the first unlicensed carrier. In such a way, a delay in sending uplink data by the terminal is reduced.
