Abstract: An evolved NodeB (eNB) for scheduling multiple Licensed-Assisted Access (LAA) cells is described that includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to perform clear channel assessment (CCA) detection and obtain a channel status at a configured Licensed-Assisted Access (LAA) secondary cell (SCell). The instructions are also executable to manage a counter. The instructions are further executable to determine whether the counter is reduced or suspended if the channel is sensed to be idle. The instructions are additionally executable to reduce the counter if determined, otherwise suspend the counter and move to a next channel sensing.

Abstract: A user equipment (UE) is described that includes a higher-layer processor configured to configure a shortened transmission timing interval (TTI) for a serving cell. The UE also includes a physical uplink channel transmitter configured to transmit a physical uplink control channel (PUCCH) on the serving cell. The UE further includes a shortened physical uplink channel transmitter configured to transmit a shortened physical uplink control channel (SPUCCH) on the serving cell. In a case that a transmission instance of the SPUCCH collides with an uplink subframe where the PUCCH is to be transmitted, the PUCCH is dropped, and the SPUCCH is transmitted.

Abstract: A user equipment (UE) is described. The UE includes a higher layer processor which is configured to acquire a dedicated Radio Resource Control (RRC) message. The UE also includes physical downlink control channel (PDCCH) receiving circuitry configured to monitor a PDCCH with a downlink control information (DCI) format which is used for scheduling of a physical downlink shared channel (PDSCH). The DCI format includes a time domain resource assignment field of which value indicates a timing of the PDSCH. The value is one of multiple possible values defined in a table. The multiple possible values include at least a first value and a second value. The first value is a predefined fixed value. The second value is configured by the dedicated RRC message.

Abstract: A method for reporting uplink control information (UCI) by a user equipment (UE) is disclosed. The method includes storing information on whether a simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission is supported. The method also includes, when the simultaneous PUCCH and PUSCH transmission is not supported and in case of a channel collision between a PUCCH and a PUSCH, transmitting, by the UE, the UCI using the PUCCH in an overlapping portion between the PUCCH and the PUSCH, and dropping the overlapping portion of the PUSCH.
