    摘要: One disclosure of the present specification provides a method for operating in relay user equipment (UE). The method may comprise the steps of: receiving a communication request message directly from a first remote UE; performing a procedure for establishing an access and mobility management function (AMF) entity and a protocol data unit (PDU) session; and storing mapping information between an identifier of a PC5 link with the first remote UE and an identifier of the PDU session on the basis of the PDU session being established for an unstructured PDU session type for unstructured traffic.

    摘要: Systems/methods are disclosed wherein a transmitter is used to convey information to a destination device by wirelessly transmitting using first frequencies; and, responsive to a size of data that is to be transmitted, wirelessly transmitting using second frequencies; wherein at least some of the second frequencies differ from the first frequencies. In some embodiments, the transmitter comprises first and second transmitters that convey information to the destination device by wirelessly transmitting by the first transmitter first data using first frequencies and, responsive to the size of data to be transmitted, wirelessly transmitting by the second transmitter second data using second frequencies. According to some embodiments, the first and second data are transmitted simultaneously in time. According to further embodiments, a smartphone comprises the transmitter or the first and second transmitters. According to additional embodiments, a base station comprises the transmitter or the first and second transmitters.

    摘要: 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.
