Abstract: A wireless transmit/receive unit (WTRU) may receive a plurality of transport blocks over a plurality of configured carriers. The WTRU may generate hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for the plurality of transport blocks, channel state information (CSI) feedback for at least one of the plurality of configured carriers, and a cyclic redundancy check (CRC). Further, the WTRU may generate a feedback message that includes a number of HARQ-ACK feedback bits for the HARQ-ACK feedback, a number of CSI feedback bits for the CSI feedback, and a number of CRC bits for the CRC. The WTRU may then determine a power to be used for a Physical Uplink Control Channel (PUCCH) transmission based on the number of HARQ-ACK feedback bits, the number of CSI feedback bits, and the number of CRC bits. Moreover, the WTRU may transmit the feedback message in the PUCCH transmission at the determined power.

Abstract: Systems, methods, and/or techniques for improving downlink spectrum efficiency may be disclosed. For example, a higher order modulation (HOM) transmission may be provided to a device. The higher order modulation transmission may be configured to be indicated by the network or a device. Additionally, multiple modulation and coding scheme (MCS) tables, transport block size (TBS) tables, and/or channel quality index (CQI) tables may be provided to support the higher order modulation transmission.

Abstract: A method and apparatus for a wireless transmit receive unit (WTRU) to use a contention-based uplink communications channel, applies a rule-based restriction of access to the contention-based uplink channel that attempts to use at least one contention-free uplink channel allocation for uplink transmissions on a condition that at least one contention-free uplink channel allocation has been granted.

Abstract: Systems, methods, and instrumentalities are provided to implement scheduling for device-to-device (D2D). A WTRU (e.g., a D2D WTRU) may determine whether the WTRU has D2D data to transmit. The WTRU may determine a set of allowed SA resources and/or allowed D2D data resources for transmission of the SA. The WTRU may select an SA resource and/or D2D data resources (e.g., from the set of allowed SA resources and/or D2D data resources) for transmission. The WTRU may select one or more transmission parameters. The WTRU may select one or more transmission patterns. The WTRU may transmit D2D data over the set of allowed D2D resources using the selected transmission patterns and according to the selected transmission parameters.

Abstract: Systems, methods, and instrumentalities are disclosed to desynchronize transmissions in group-based operations. A group user equipment (UE), e.g., a UE that is a member of a group of UEs, may be in an inactive mode. The group UE may receive a multicast message indicating that the group UE may enter an active mode. For example, the group UE may use the active mode for periodic reporting of its monitoring activity to the network. The multicast message may indicate a mechanism for the group UE to use to send an uplink transmission to the network. The group UE may send the uplink transmission to the network at a transmission time indicated by the mechanism. The transmission time may be desynchronized from other UEs in the group.

Abstract: A wireless transmit/receive unit (WTRU) is configured to receive a reference signal of a first type. The reference signal of the first type is other than a cell specific reference signal (CRS), an Multicast Broadcast Single Frequency Network (MBSFN) reference signal or a demodulation reference signal (DM-RS). Reference signals of the first type are received in resource elements other than resource elements used for a physical broadcast channel (PBCH), 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, and a number of antenna ports for a transmission of the reference signal of the first type.

Abstract: A method and apparatus for sending uplink control information by a multi-mode wireless transmit/receive unit (WTRU) capable of operating on multiple component carriers of a plurality of radio access technologies (RATs) for multi-RAT operation are disclosed. The WTRU may generate uplink control information (UCI) pertaining to a first RAT and a second RAT, wherein the UCI may include a first plurality of hybrid automatic repeat request acknowledgements (HARQ-ACKs) pertaining to a plurality of downlink (DL) transmissions of the first RAT and a second plurality of HARQ-ACKs pertaining to a plurality of DL transmissions of the second RAT. The WTRU may multiplex at least part of the generated UCI pertaining to the first RAT and at least part of the generated UCI pertaining to the second RAT onto a physical channel on a component carrier of the second RAT.
