The method can include performing a LBT on the carrier frequency for a time duration that at least partially overlaps a terminal portion of a subframe duration of a first subframe of the plurality of subframes. The method can include determining a position of a starting OFDM symbol for transmitting a control channel in a second subframe of the plurality of subframes based on the time duration of the LBT. The subframe duration of the second subframe can occur immediately after the subframe duration of the first subframe.

  • Patent number: 10581547
    Abstract: Briefly, the present disclosure is directed to methods and apparatus that allow for the synchronization with, and measurement reporting of, unlicensed frequency carriers. A method and apparatus for synchronizing to an Scell operating on an unlicensed carrier determine, at a UE (108, 116), one or more measurement instances where a discovery signal may be transmitted, for example, by a base station (132), on the Scell from a higher layer configuration message. The method and apparatus may monitor a control channel for a control channel message and determine whether the discovery signal will be transmitted during one or more measurement instances on the Scell. The method and apparatus may detect the discovery signal transmission on the Scell during one or more of the measurement instances. The method and apparatus may also synchronize to and/or measure the Scell based on detected discovery signal transmissions.

  • Patent number: 10516461
    Abstract: Devices and methods of beamforming are generally described. A UE transmits to an eNB a BRSRP report having selected BRSRP values and associated BRS IDs. An active link list, a CSI resource indication, and a first active link are used to measure the CSI resource and CSI feedback is sent. A serving link ID is provided to indicate a second active link to use for control and data reception. Rx beams are trained based on multiple instances of each BRS and the eNB supplies selection criteria for the BRSRP report. The Rx beams are refined based on BRRS and the second active link is dependent on BRRSRP or CSI feedback. When configured for dual beam operation, the BRSRP feedback corresponds to BRSRP value pairs and dual Rx beams associated with a pair of serving link IDs are used.
