Abstract

Disclosed herein is an apparatus of a user equipment (UE) configured to communicate with an evolved Node B (eNB). The UE may include memory and processing circuitry coupled to the memory. The processing circuitry may be configured to decode control information received on one or more channels of unlicensed spectrum. The control information includes indication that a grantless uplink (UL) transmission is allowed without a prior UL grant. The processing circuitry is further configured to perform a listen-before-talk (LBT) procedure on the one or more channels of the unlicensed spectrum to determine if one of the channels is available. Upon determining the channel is available, the processing circuitry can encode UL control information and data for transmission using the grantless UL transmission. The grantless uplink transmission is an unscheduled transmission, performed on the channel without an UL grant.
