Abstract:
Autonomous uplink (UL) transmission can be enabled for user equipments (UEs) to generate on unlicensed spectrums that are shared among different UEs of a network. A UE can generate the autonomous UL transmission within a gap period of a transmission opportunity (TxOP) without a corresponding UL grant. The UE performs a listen before talk (LBT) operation within the gap period of a TxOP. Based on the LBT, the autonomous UL transmission can be communicated on an unlicensed channel that is shared among the different UEs.

The first circuitry may be operable to determine a preferred UE beam. The second circuitry may be operable to generate a Physical Random Access Channel (PRACH) transmission associated with a preferred eNB beam for transmission on the preferred UE beam. The third circuitry may be operable to process a Random Access Response (RAR) transmission carrying Timing Advance (TA) received through the preferred UE beam. The apparatus may also comprise an interface for sending the PRACH transmission to a transmission circuitry and for receiving the RAR transmission from a receiving circuitry.
Abstract:
Methods and apparatus are described by which user equipment (UE) transmits data over unlicensed spectrum using systems, such as MulteFire and enhanced Licensed-Assisted Access (eLAA) systems. Embodiments transmit data over a physical uplink shared channel (PUSCH) channel to an evolved Node B (eNB) without first receiving an uplink (UL) grant from the eNB. Embodiments of downlink control information (DCI) and its transmission and channel sensing schemes are described that contain information that may be used by the UE to transmit data over unlicensed spectrum.
