Abstract: Licensed assisted access (LAA) uplink (UL) transmissions can be performed using UL scheduling, enhanced node B (eNB) listen before talk (LBT), and user equipment (UE) LBT. A scheduling of a UE for UL transmission can include different procedures for a UE to perform LBT before UL transmission. These procedures can be classified as: i) a scheduled UE performing no LBT for UL transmission, ii) a scheduled UE performing fast LBT (as compared to the eNB) with a more aggressive choice of parameters than the eNB and iii) a scheduled UE performing LBT using parameters as used by the eNB for LBT. In some embodiments, the UL grant transmission by the eNB occurs in the unlicensed band after a successful LBT procedure at the eNB.

When the propagation number is equal to the total number, the second configuration unit sets a port in the transfer destination information to the mirror output port.

Abstract: A method for channel signaling is described. The method includes determining (e.g., by a UE) whether at least one DL subframe is a valid reference resource. If the at least one DL subframe is not a valid reference resource, reporting measurements of a DL channel measured during the at least one DL subframe is inhibited. The method may include determining (e.g., by an eNB) whether reporting of the at least one DL subframe of a DL channel is required. If reporting is not required, a message configured to cause the at least one UE to inhibit reporting measurements of the DL channel (e.g., CQI measurements) measured during the at least one DL subframe is sent to the UE. Determining whether the at least one downlink subframe is a valid reference resource is based at least in part on the message. Apparatus and computer readable media are also described.
