  • Publication number: 20200260383
    Abstract: A data transmission method provided in embodiments of the present application includes: determining, by a mobility management entity MME, that user equipment UE changes from an unreachable state to a reachable state; sending, by the MME, a request message to a serving gateway SGW; receiving, by the MME, downlink data sent by the SGW; and sending, by the MME, the downlink data to the UE. In this way, when the UE changes to a reachable state for downlink data, the MME requests the SGW to send the downlink data, and the MME then sends the downlink data to the UE, thereby avoiding loss of the downlink data caused by delivery of the downlink data to the UE that is in an unreachable state, and improving real-time accuracy of transmission.

  • Patent number: 10728924
    Abstract: A guard period for switching between uplink and downlink subframes is created by shortening an uplink subframe, i.e., by not transmitting during one or more symbol intervals at the beginning of the subframe interval. A grant message includes signaling indicating when a shortened subframe should be transmitted. An example method is implemented in a first wireless node configured to transmit data in transmit subframes occurring at defined subframe intervals and having a predetermined number of symbol intervals. This example method includes determining (1620) that a transmit subframe is to be shortened, relative to the predetermined number of symbol intervals and, in response to this determination, shortening (1630) transmission of the transmit subframe by not transmitting during a beginning portion of the subframe interval for the transmit subframe and transmitting during the remainder of the subframe interval.
