摘要： A method for reporting uplink control information (UCI) on a user equipment (UE) is described. A second channel state information (CSI) report is transmitted. The second CSI report is computed from interference measurements only on a subframe of the CSI reference resource. A first CSI report is computed from interference measurements based on an unrestricted observation interval in time and frequency. The CSI reference resource for the second CSI report reported in uplink subframe n is defined by a valid downlink subframe n−k.

摘要： As a result of the selection/reselection operation, a wireless terminal (26) selects the high priority candidate frequency for use in the device-to-device (D2D) communications. During the cell selection/reselection operation, the wireless terminal (26) is required to consider selection/reselection candidate frequencies at which the wireless terminal (26) cannot receive or transmit device-to-device (D2D) signals to be of low priority candidate frequencies when the wireless terminal (26) is capable of device-to-device (D2D) communications and is receiving or transmitting, or anticipating receiving or transmitting, device-to-device (D2D) signals on device-to-device (D2D) supported frequencies. In another basic mode predefined RRC Idle Mode state transition(s) are used to determine when a wireless terminal (26) encounters an out-of-coverage situation for device-to-device (D2D) communications purposes; and when the out-of-coverage situation is determined, the wireless terminal (26) uses pre-configured device-to-device (D2D) radio resources for the device-to-device (D2D) communications.

摘要： A node of a radio access network (22) communicates with a wireless terminal (261) over a radio interface and sends to the wireless terminal (261) an indication (62) which specifies, for device-to-device (D2D) communications with another wireless terminal (262), whether the wireless terminal (261) is to use network-allocated radio resources or radio resources which are selected by the wireless terminal.

摘要： A User Equipment (UE) is described. The UE decodes an uplink/downlink (UL/DL) reconfiguration downlink control information (DCI) with an enhanced interference mitigation with traffic adaptation (eIMTA)-radio network temporary identifier (RNTI) on a physical downlink control channel (PDCCH). The UE also determines if one or more valid UL/DL configurations in the UL/DL reconfiguration DCI with eIMTA-RNTI for all configured eIMTA cells are received. The UE further determines if physical uplink control channel (PUCCH) format 3 is configured. The UE additionally determines a PUCCH resource for physical downlink shared channel (PDSCH) hybrid automatic repeat request acknowledgement/negative acknowledgement (HARQ-ACK) reporting based on whether valid UL/DL configurations in the UL/DL reconfiguration DCI with eIMTA-RNTI for all of the configured eIMTA cells corresponding to a subframe for the PUCCH resource are received. The UE also sends PDSCH HARQ-ACK information on the selected PUCCH resource in an uplink subframe.

摘要： A UE for performing carrier aggregation is described. The UE determines a duplex method of each serving cell for carrier aggregation. A primary cell is a FDD cell. When transmitting PDSCH HARQ-ACK information on a PUSCH or using a PUCCH format 3 in a later subframe, the UE generates two NACKs for a PDSCH transmission in an earlier subframe for a serving cell when a configured downlink transmission mode supports up to two transport blocks, the serving cell is a TDD cell and an earlier subframe is an uplink subframe for the serving cell. The UE further generates a single NACK for a PDSCH transmission in an earlier subframe for a serving cell when a configured downlink transmission mode supports a single transport block, the serving cell is a TDD cell and an earlier subframe is an uplink subframe for the serving cell.

摘要： A User Equipment (UE) for performing carrier aggregation is described. The UE includes a processor and instructions stored in memory that is in electronic communication with the processor. The UE determines an uplink control information (UCI) transmission cell in a wireless communication network with at least one frequency-division duplexing (FDD) cell and at least one time-division duplexing (TDD) cell. The UE also selects a first cell for FDD and TDD carrier aggregation. The UE further determines a set of downlink subframe associations for the first cell that indicate at least one UCI transmission uplink subframe of the UCI transmission cell. The UE additionally sends Physical Downlink Shared Channel (PDSCH) Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement (HARQ-ACK) information in the UCI transmission uplink subframe of the UCI transmission cell.
