    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.

    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: Coexistence gaps may permit one radio access technology (RAT) to coexists with another RAT by providing period in which one RAT may be silent and another may transmit. Methods may account for the RAT traffic and for the presence of other secondary users in a channel. Methods may be provided to dynamically change the parameters of a coexistence gap pattern, such as the duty cycle, to adapt to both the RAT traffic and the presence of other secondary users. Methods may include PHY methods, such as synchronization signal (PSS/SSS) based, MIB based, and PDCCH based, MAC CE based methods, and RRC Methods. Measurements may be provided to detect the presence of secondary users, and may include reporting of interference measured during ON and OFF durations, and detection of secondary users based on interference and RSRP/RSRQ measurements.

    Abstract: Methods and apparatuses are described herein for configuration of background data transfers (BDTs) between local area data networks (LADNs). An apparatus may receive a message indicating a request from a user equipment (UE) for a data transfer of data originating from the UE. The apparatus may send, to a database, a request for subscription information associated with the UE and a policy profile associated with the UE to determine whether there is an existing BDT policy. The apparatus may receive, from the database, a response indicating whether there is an existing BDT policy that can be re-used. The apparatus may determine, based on the received response, a BDT policy for the data transfer and a LADN to service the data transfer. The apparatus may send, to the LADN via a radio access network (RAN) node, a notification message of an arrival time and data rate for the data transfer.

    Abstract: Methods and apparatuses are described herein for multi-subscriber identification module (SIM) connected mode operation. In one embodiment, a wireless communications device may receive, from an access stratum interface, a request access to the receiver chain during a receiving opportunity. The wireless communications device may determine that the receiver chain is available during the receiving opportunity. The wireless communications device may send a response indicating access is granted to cause the access stratum interface to receive a downlink transmission during the receiving opportunity. The wireless communications device may receive, from the access stratum interface, a second request for a transmitter chain during a transmitting opportunity. The wireless communications device may determine that the transmitter chain is available during the transmitting opportunity. The wireless communications device may send a second response indicating access is granted to enable the access stratum interface to transmit an uplink transmission during the transmitting opportunity.
