  • Patent number: 10547494
    Abstract: This disclosure includes methods, systems, and devices for wireless communication. A repetition of symbols may be used to increase a device's ability to synchronize and communicate using unlicensed spectrum. For example, a base station may schedule a frame that includes repetitions, in time or frequency, of a control or data signal. After performing a listen-before-talk (LBT) procedure, the base station may broadcast or transmit the frame to one or more devices, such as a user equipment (UE). For instance, the frame may include repetitions of a discovery reference signal (DRS), and be broadcast by the base station to enable synchronization by the UE. In other examples, the signal may include repetitions of a cell-specific reference signal (CRS), and a UE may identify a start of a transmission opportunity using the CRSs. Other signals, such as downlink control and shared channels, may be repeated within a frame in a similar manner.

  • Patent number: 10548131
    Abstract: A method and apparatus for wireless communication in the unlicensed spectrum between an eNB and UEs having different bandwidths, e.g., between a narrowband UE and a wideband eNB. A base station apparatus performs an LBT procedure at a beginning of frames and transmits a plurality of repetitions of a transmission. When the plurality of repetitions span multiple frames and the LBT procedure is not successful for a first frame, the base station drops or postpones at least one repetition in the first frame until a second frame when the LBT procedure is successful. A UE receives the plurality of repetitions and may combine a plurality of repetitions across multiple frames. The UE may determine whether the base station drops the at least one repetition in the first frame or postpones the at least one repetition in the first frame until a second frame.
