Abstract: A wireless transmit/receive unit (WTRU) may initiate a random access. The WTRU may determine whether to select a first random access channel (RACH) procedure or a second RACH procedure for the random access. The first RACH procedure may be a legacy RACH procedure. The second RACH procedure may be an enhanced RACH (eRACH) procedure. The WTRU may determine whether to select the first RACH procedure or the second RACH procedure based at least on a type of uplink data to be transmitted. When the second RACH procedure is selected, the WTRU may determine at least one physical random access channel (PRACH) resource associated with the second RACH procedure. The WTRU may determine a preamble sequence associated with the second RACH procedure. The WTRU may determine a data resource for the uplink data. The WTRU may send a RACH transmission that includes the preamble sequence and the uplink data.

Abstract: Methods and devices may be provided for aggregating component carriers in the licensed spectrum with at least one component carriers in the licensed exempt spectrum. Control information may be processed in a wireless transmit/receive unit (WTRU) while receiving and sending information on a primary component carrier (PCC) and a supplementary component carrier (SuppCC). A PCC subframe with a control portion and a data portion may be received. Resource assignment information associated with a downlink shared channel on the PCC may be embedded in the control portion of the subframe. Based on the resource assignment information on the PCC, resource assignment information associated with a downlink shared channel on the SuppCC may be identified in the data portion of the PCC subframe. A SuppCC subframe of the shared channel on the SuppCC may be processed as per the identified resource assignment information associated with the downlink shared channel on the SuppCC.

Abstract: Systems, methods, and instrumentalities are disclosed to schedule user equipment (UE) measurements. An HeNB may identify a first cluster of UEs and a second cluster of UEs. The HeNB may determine a measuring gap schedule relating to the first cluster of UEs and the second cluster of UEs. The measuring gap schedule may indicate a measurement time for each cluster. The measurement time may indicate that UEs in a cluster withhold a transmission during the measurement time. The UEs in the cluster may measure a spectrum (e.g., frequency, channel, etc.) associated with a supplementary cell during the measurement time. The HeNB may send the measuring gap schedule to the first cluster of UEs and the second cluster of U Es. The HeN B may receive spectrum measurements of the supplementary cell from the first cluster of UEs and the second cluster of UEs, e.g., in accordance with the measuring gap schedule.

Abstract: Methods and apparatus for shared access systems may be used to allow operation in three-tiered shared spectrum architecture. For example, a Shared Spectrum Manager (SSM) may organize spectrum segments. The SSM may communicate with access users of different priority and may use message exchanges to request spectrum, bid for spectrum, manage spectrum, or the like. The SSM may manage admission of access users (allocation of spectrum to users) and operation with a spectrum request that may be provided as a range between a minimum (guaranteed) and maximum quality of operation. The SSM may also manage the way an access user may use the assigned spectrum. Inter-SSM communication may be used in regions where multiple SSMs may exist (e.g. country borders). Accordingly, triggers for this inter-SSM communications and corresponding actions are also disclosed herein.

Abstract: A system, apparatuses and methods are provided for communicating in an opportunistic band. Channels that are reserved for primary users are used by sensing devices when primary users are not present. A geo-location database is configured to store occupancy information of a channel and information associated with the primary user of the channel. The database includes information such as the type of primary user, and the expected occupancy time of a channel by a primary user. Sensing devices are categorized into different classes based on their sensing capability. A device capabilities database stores device classification information associated with the sensing devices attached to a dynamic spectrum management system.

A centralized gateway CGW (210, 710) may be provided to facilitate the assistance via client devices in the networks (220). The CGW (210, 710) and client devices may use a common protocol (311) and common interface to take actions relating to the assistance (780).

Abstract: Systems, methods, and instrumentalities are disclosed to provide feedback to a user equipment (UE). A UE may transmit uplink data via a supplementary cell. A network device, such as a HeNB, eNB, etc., may receive the uplink data from the UE via the supplementary cell. The network device may send feedback associated with the uplink data to the UE via a physical downlink shared channel (PDSCH) when downlink data is available for transmission to the UE. The feedback may be physical hybrid ARQ indicator channel (PHICH) ACK/NACK information. The feedback sent via the PDSCH may be multiplexed with the downlink data. The network device may send the feedback associated with the uplink data to the UE via a physical downlink control channel (PDCCH) when downlink data is not available for transmission to the UE.

Abstract: Systems, methods, and apparatus may be used to provide assistance for connection procedures in a hierarchical network where macro cells may be operating in licensed spectrum while small cells may be operating in dynamic and shared spectrums, such as TVWS. This may be done, for example, to allow an LTE system performing carrier aggregation (CA) to reconfigure itself to change from a supplementary cell (SuppCell) in one dynamic and shared spectrum channel to a SuppCell in another dynamic and shared spectrum channel.

Abstract: Systems and methods are provided for coexistence management service for licensed and unlicensed spectrum sharing. A coexistence system may include a coexistence manager (CM) that may provide resource allocation services for a coexistence enabler (CE). CMs may negotiate with each other to resolve coexistence issues via directly or indirectly through a coexistence discovery and information server (CDIS). A channel may be exclusively used by a CE network. The networks may mitigate interference by avoiding use of the same channels. A channel may be shared by multiple CE networks. In co-channel sharing, the networks may mitigate interference via power management. Bidding processes may be implemented directly via competing CMs, for example via open or silent token auction. Bidding processes among competing CMs may be managed by a third party entity, for example a CDIS, for example via open or silent token auction.

Abstract: A wireless network may implement a reduced bandwidth for control information transmitted and/or received on the wireless network. The reduced bandwidth may be used to avoid interference that may be detected from an in-band or adjacent channel. The reduced bandwidth may be used for transmission and/or reception of control information on a cellular or Wi-Fi channel. An eNB or an access point (AP) may signal to a wireless transmit/receive unit (WTRU) information associated with the reduced control channel, such as the power and/or the location of the channel in a frequency band. The control channel may be shifted to avoid a change in interference.

Abstract: Methods and apparatus for effecting power control as well as frequency and timing synchronization in an LTE component carrier functioning in UL-only mode or device-to-device mode, including a UL-only cell in LTE, as well as an new enabling Special Uplink Reference Signal (SURS) that is used to determine the UEs that can take advantage of a UL-only cell. One approach includes interrupting the UL-only operation in a periodic fashion to send a sync signal by the eNB. Another approach includes sending a well know synchronization sequence by the UEs in a periodic fashion, which the eNB compares with its own local frequency reference and sends feedback to the UE to readjust the frequency. Another approach uses dedicated subcarriers where the eNB can send synchronization symbols on the same channel and simultaneously with data being transmitted in the uplink. The UEs transmitting in the UL direction are equipped to receive simultaneously the synchronization symbols on these dedicated subcarriers.
