Abstract: Channel state information is reported in periodic and aperiodic reports for multiple component carriers or serving cells. Channel state information may be reported for a subset of aggregated downlink carriers or serving cells. For an aperiodic report, the carrier(s)/serving cell(s) for which channel state information is reported are determined based on the request for the aperiodic report. When a CQI/PMI/RI report and a HARQ ACK/NACK report coincide in a subframe, the HARQ ACK/NACK report is transmitted on PUCCH, and the CQI/PMI/RI report is transmitted on PUSCH.

Abstract: A wireless transmit receive unit (WTRU) is configured to receive a reference signal of a first type. The first type is other than a demodulation reference signal (DM-RS). Reference signals of the first type are received in resource elements other than resource elements used for a primary synchronization signal or a secondary synchronization signal. The WTRU is configured to receive a radio resource control message indicating a subframe position in which the reference signal of the first type is transmitted and a periodicity of a transmission of the reference signal of the first type.

Abstract: A wireless transmit/receive unit (WTRU) may receive configuration information indicating a plurality of sets of resource elements (REs). Each of the plurality of sets of REs may be associated with a Channel-State-Information Reference Signal (CSI-RS) configuration. Also, the WTRU may receive a request in a Downlink Control Information (DCI) signal, in a first time unit, to receive at least one CSI-RS, in at least one set of the plurality of sets of REs, in the first time unit, to perform a measurement and to report the measurement; and the request may indicate the at least one set of the plurality of sets of REs. Further, the WTRU may receive the at least one CSI-RS, in the at least one set of the plurality of sets of REs, in the first time unit, according to the request. Moreover, the WTRU may perform the measurement of the at least one CSI-RS.

Abstract: Device-to-device (D2D) cross link power control systems and methods may be disclosed. For example, a device such as a UE or WTRU may determine whether it may have simultaneous transmissions where at least one of the transmissions may include a cross link transmission. The device may further determine whether a total transmit power of the simultaneous transmissions may exceed a maximum transmit power of the device. If the device may have simultaneous transmissions and such transmissions may exceed the maximum transmit power, the device may reallocate power based on a priority or priority setting. The device may further determine a maximum cross link power, a maximum device power, and a cross link transmit power level such that the device may further control the power for transmissions based thereon.

Abstract: Systems, methods, and instrumentalities are disclosed to determine access control and channel and signaling priority. A wireless transmit/receive unit (WTRU) may comprise a processor configured, at least in part, to determine device-to-device (D2D) data to be transmitted. The WTRU may determine if the D2D data may be transmitted. The WTRU may determine available scheduling assignment (SA) resources used for priority based D2D data signals. The WTRU may select one or more available SA resources used for priority based D2D data signals. The WTRU may transmit the D2D data, wherein the D2D data may be transmitted on the selected SA resources.

Abstract: Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

Abstract: Physical layer processing and procedures for device-to-device (D2D) discovery signal generation and transmission and scheduling of D2D discovery signals are described. Detection and measurement of a D2D discovery signal, D2D signal identity management, and monitoring by a wireless transmit/receive unit (WTRU) of PDCCH for D2D discovery scheduling is described, as is a WTRU that may be configured with a D2D-specific transmission/reception opportunity pattern. The discovery signal may carry a payload for explicit information about user and/or service identity, and may be mapped to physical resources in such a way as to decouple transmission/reception of the discovery signal from downlink operations. A WTRU may measure a D2D discovery signal quality and report to the network.

Abstract: Systems, methods, and instrumentalities are disclosed for LTE operation in an unlicensed spectrum, LTE-U. A wireless transmit/receive unit, WTRU, may establish a connection with a first cell on a licensed frequency band. The WTRU may receive a first downlink transmission from a second cell operating on an unlicensed frequency band. The WTRU may determine that a synchronization signal transmission from a third cell operating on the unlicensed frequency band is transmitted using one or more resource elements. The WTRU may perform frequency and/or timing estimation based on the synchronization signal transmission. The WTRU may perform rate matching around the one or more resource elements that correspond to the synchronization signal transmission. The WTRU may perform rate matching around the one or more resource elements by de-mapping symbols of the downlink transmission.

Abstract: Systems, methods, and instrumentalities are disclosed for Uplink operation in LTE unlicensed spectrum (LTE-U). A wireless transmit/receive unit (WTRU) may receive licensed assisted access (LAA) configuration information, e.g., for a first cell from a second cell. The first cell may be associated with operation in an unlicensed band, and the second cell may be associated with operation in a licensed band. The WTRU may determine whether a first subframe is a sounding reference signal (SRS) subframe for the first cell. If the first subframe is an SRS subframe for the first cell, the WTRU may determine SRS resources for the first subframe and determine whether the WTRU is triggered to transmit an SRS transmission in the first subframe. If it is determined the WTRU is triggered to transmit the SRS transmission in the first subframe, the WTRU may transmit the SRS transmission on the SRS resources for the first subframe.

Abstract: Methods and systems are disclosed for reducing control signaling in uplink transmissions. A device, such as a wireless transmit/receive unit, may determine to use a demodulation reference signal (DM-RS) transmission schedule out of a plurality of DM-RS transmission schedules. The DM-RS transmission schedule may be characterized by a DM-RS transmission being mapped to a single orthogonal frequency-division multiplexing (OFDM) symbol per subframe of a data stream. The DM-RS transmission schedule may be characterized by a DM-RS transmission being mapped to a first subset of subcarriers of an OFDM symbol of a subframe of a data stream and Physical Uplink Shared Channel (PUSCH) transmission or Physical Uplink Control Channel (PUCCH) control information being mapped to a second set of subcarriers of the OFDM symbol. The first set of subcarriers may be different than the second set of subcarriers. The data stream may be transmitted according to the DM-RS transmission schedule.
