Abstract: A License Assisted Access (LAA) enhanced NodeB (eNB), user equipment (UE) and communication methods therebetween operating in a Long Term Evolution unlicensed band (LTE-U) are generally described. The eNB may transmit a request to the UE for information regarding a Wireless Local Area Network (WLAN) over which the UE may be able to communicate. The WLAN information may include an LTE-U channel and time window for reporting. The UE may obtain the WLAN information through communication with an access point (AP). Measurement information of the LTE-U channel may also be obtained by or on behalf of the UE. The UE may transmit the WLAN information to the eNB. The eNB may use the WLAN information or submit the WLAN information to a network entity to perform channel selection, UE grouping or localization, appointing delegate UEs to perform channel sensing or scheduling UEs in a same group or proximity.

Abstract: Embodiments described herein relate generally to a random procedure between wireless transmit/receive units (“WTRUs”) and access nodes. A WTRU may be adapted to determine a repetition level that corresponds to a number of repetitions associated with communication with the access node. The WTRU may then determine at least one of a resource and/or a logical root sequence index associated with the random access procedure. The WTRU may transmit a random access preamble based on the resource and/or a logical root sequence index. The access node may be adapted to determine a repetition level associated with the WTRU based on the random access procedure. Other embodiments may be described and/or claimed.

Abstract: Embodiments of a User Equipment (UE) to operate in accordance with a physical random access channel (PRACH) are disclosed herein. The UE may comprise hardware processing circuitry to determine a coverage enhancement category for the UE based on downlink channel statistics related to reception of downlink signals at the UE from an Evolved Node-B (eNB) and an uplink-downlink imbalance parameter related to uplink reception at the eNB. The hardware processing circuitry may be further to select, for use in a coverage enhancement mode, a PRACH preamble from a set of candidate PRACH preambles based on the determined coverage enhancement category for the UE. In some embodiments, at least some of the candidate PRACH preambles may span a different number of sub-frames.

The two or more tables include a default table and a secondary table. The default table and the secondary table have a matching number of entries, and the secondary table includes an entry corresponding to a 256-QAM scheme. The table selection component is configured to select a selected table from one of the default table and the secondary table. The communication component is configured to receive and process a communication from a base station based on a modulation and coding scheme of the selected table.

Abstract: The techniques introduced here provide for device discovery of a greater number of mobile devices in a mobile network by increasing the multiplexing capacity of the system. The techniques may be applied to device-to-device communication networks and small cells using low power nodes (e.g., pico and femto eNodeB in a 3GPP LTE or LTE advanced network). Additionally, the techniques provide for mapping between a mobile device ID and an orthogonal resource of the discovery signal.
