Abstract:
A method of managing carrier aggregation for a multi-radio access technology (RAT) wireless transmitter/receiver unit (WTRU) is disclosed. The method may include: receiving, by the WRTU over a primary channel associated with a RAT of a first type, provisioning information for provisioning a supplementary channel associated with a RAT of a second type; establishing the supplementary channel associated with the RAT of the second type based on the received provisioning information; and wirelessly exchanging, by the WRTU, first data associated with a communication over the primary channel via the RAT of the first type, while wireless exchanging second data associated with the communication over the supplementary channel via the RAT of the second type.
Abstract:
Apparatuses and methods of flow-based processing is wireless systems are described. For example, in one method, a WTRU may determine that one or more data units correspond to a flow of such data units. The WTRU may perform such determination as a function of one or more matching rule(s). Flow-based processing may be enabled in the layer 2/layer 1 chain by per-packet determination using one or more rules, for example by routing through the applicable processing functions and/or using the applicable configuration and/or mapping to the applicable uplink physical layer functions and/or resources. One or more functions such as scheduling request, buffer status reporting, HARQ processing, and/or radio link failure and recovery may be controlled based on the policy associated with the flow corresponding to the data being processed.

Systems, methods, and instrumentalities are disclosed for a WTRU to act as a mobile relay, the method comprising the WTRU connecting to the network, the WTRU receiving a message from the network indicating that the WTRU is to act as a mobile relay for one or more devices outside of the coverage of the network, the WTRU discovering one or more devices outside of the coverage of the network, and the WTRU receiving a message from the out-of-coverage device that indicates that the out-of-coverage device has selected the WTRU to act as a mobile relay.
Abstract:
A method, apparatus, and system of a User Equipment (UE) device executing communications using a Device-to-Device (D2D) Long Term Evolution (LTE) network are provided. The method includes determining D2D devices communicating in an area, determining whether D2D data is to be transmitted, determining one or more resource sets for transmitting the D2D data, and transmitting the D2D data using the determined one or more resource sets.
Abstract:
Disclosed herein are system and method embodiments for selection of transmission parameters for transmit diversity terminals. According to an aspect, a method for controlling wireless receive/transmit unit transmission parameters may include configuring a WRTU to transmit dual stream when a first stream is using a predetermined transport format (TF) or subset of the TF. The method may also include applying the configuration to the WRTU.
Abstract:
A method and apparatus for configuring a Long Term Evolution (LTE)-controlled Wireless Local Area Network (WLAN) interface for a wireless transmit/receive unit (WTRU) are described. A method includes receiving LTE Radio Resource Configuration (RRC) signaling that provides parameters for the WTRU to configure the LTE-controlled WLAN interface. The LTE RRC signaling includes a set of WLAN access points (APs), an indication that the WTRU is permitted to autonomously initiate association with a WLAN within the set, a type of one or more bearers to use for the LTE-controlled WLAN interface, WLAN-related security information, and a configuration for the WTRU to report a status of an association with a WLAN AP. The WTRU selects a WLAN AP to associate to from the list and initiates association to the selected WLAN AP using at least the WLAN-related security information.
Abstract:
Uplink precoding in closed loop transmit diversity (CLTD). The methods and apparatus relate to precoder operations during an initial stage using default precoder tap weights, and a second stage wherein precoder weights obtained from a precoder control indicator channel information are used, provided the signal quality of the precoder control indicator channel is sufficiently reliable. The methods and apparatus also relate to procedures for responding to detection of an unreliable pre-coding control information (PCI) carried in a downlink feedback signal.
Abstract:
A method for acquiring and applying offload area information for offloading a wireless transmit/receive unit (WTRU) to a small cell in a different frequency layer is disclosed. The WTRU may enter a region or a macro cell and receive offload area information of the region in which a small cell in the vicinity of the macro cell is located. The offload area information may include at least one of a global positioning system (GPS) coordinate, a radius over which the area extends with respect to the GPS coordinate, a list of position reference signals (PRS), a cell identity or a list of cell identities, a frequency on which the small cell is located, and a radio access technology (RAT) of the corresponding cell. The offload information may be received in a system information block (SIB), dedicated signaling, or any other radio signal. The WTRU may perform measurements to determine the location of the WTRU and to determine whether it has entered any offload areas. Upon a determination that the offload area information is no longer valid, the WTRU may delete the offload area information.

Abstract:
A method, apparatus, and system for multiple wireless transmit/receive units (WTRUs) communicating with a base station are disclosed. A base station, such as an eNB, may assign each WTRU of a plurality of WTRUs a portion of a transmission time interval (TTI) and then send that assignment to each respective WTRU in a control channel. The base station may then send data to one or more WTRUs in their respective assigned portions on a physical downlink shared channel (PDSCH). The portion may be one or a plurality of a time slots. The portion may be a fraction of the TTI.
