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 processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to acquire a first higher layer configuration indicating multiple sets of physical uplink control channel (PUCCH) resources, the multiple sets of PUCCH resources including at least a short PUCCH resource. The instructions are also executable to select a PUCCH resource from the sets of PUCCH resources. The instructions are further executable to transmit uplink control information (UCI) on the selected PUCCH resource.

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 user equipment (UE) is described. The UE receives, from a base station apparatus, a radio resource control message including first information used for configuring a number of repetitions for transmission of a transport block. The UE also receives, from the base station apparatus, a radio resource control message including second information used for configuring a pattern of redundancy version for the repetitions for the transmission of the transport block. The pattern of the redundancy version is any one of a first pattern and a second pattern. The UE also performs, based on the first information and the second information, to the base station apparatus, the repetition for the transmission of the transport block. The same redundancy version used for the repetitions for the transmission for the transport block is a redundancy version “zero.”

Abstract: A user equipment (UE) is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to acquire a first higher layer configuration indicating at least a short uplink control channel (PUCCH) resource configuration. The instructions are also executable to acquire a second higher layer configuration indicating multiple sets of PUCCH resource configurations, one set of PUCCH resource configurations within the multiple sets of PUCCH resource configurations include the short PUCCH resource configuration. The instructions are further executable to select a set of PUCCH resource configurations from the sets of PUCCH resource configurations based on a payload size of uplink control information (UCI). The instructions are additionally executable to transmit the UCI on a PUCCH resource, the PUCCH resource corresponding to a PUCCH resource configuration within the selected set of PUCCH resource configurations.

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.

Abstract: A user equipment (UE) is described. The UE may include a physical downlink control channel (PDCCH) receiver that is configured to detect multiple PDCCHs in a subframe i−K, the multiple PDCCHs including a first PDCCH. The UE may also include a physical uplink shared channel (PUSCH) transmitter that is configured to transmit multiple PUSCHs, the multiple PUSCHs being transmitted in a license-assisted access (LAA) cell, the multiple PUSCHs including a PUSCH which is scheduled by the first PDCCH, the PUSCH being transmitted in a subframe i. A transmit power of the PUSCH may be derived using a value indicated by a transmit power control (TPC) command field which is included in the first PDCCH.
