Abstract: A terminal apparatus includes a receiver configured to receive a DCI format including an uplink grant, and a transmitter configured to transmit a PUSCH or an sPUSCH based on the uplink grant. A TTI of the PUSCH is one sub-frame. A TTI of the sPUSCH is shorter in value than one slot. In a case that a transmission of a channel quality indicator is triggered in response to a transmission of the PUSCH, the uplink control information is transmitted in the PUSCH. In a case that a transmission of a channel quality indicator is triggered in response to a transmission of the sPUSCH, a transmission of the uplink control information is dropped.

Abstract: An offloading controller for traffic offloading in a multi-radio-access-technology (RAT) network is described. The offloading controller includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to determine a channel utilization threshold based on a likelihood of packet collisions in a contention-based access network. The multi-RAT network comprises a centralized resource management network and the contention-based access network. The instructions are also executable to determine whether to offload one or more user equipments (UEs) on the contention-based access network to the centralized resource management network by comparing a current channel utilization of the contention-based access network and the channel utilization threshold.
