Abstract: A method includes transmitting, at an LTE device configured to transmit data over an unlicensed band, first synchronization data over a first frequency channel of the unlicensed band during a timeframe. The method further includes transmitting, at one of the first LTE device or a second LTE device, second synchronization data over a second frequency channel of the unlicensed band during the same timeframe. The data transmissions of at least one of the first LTE device or the second LTE device are coordinated based on the synchronization data.

Abstract: Carrier aggregation and dual connectivity allow a user device to communicate with one or more base stations on multiple component carrier frequencies. When it is determined that the user device should handover to a new base station, the user device performs a substantial portion of the needed handover operations with the new base station using only one of the component carrier frequencies. Meanwhile, the user device maintains data communications with the original base station on the remaining component carrier frequencies.

Abstract: TTI bundling is included for Msg3 transmissions in LTE communications. A reserved group of preambles or reserved set of random access preamble transmission opportunities are used to indicate user equipment (UE) need of uplink (UL) transmission of a TTI-bundled Msg3. The UE transmits the same redundancy version for transmissions within a TTI bundle as the eNB expects even if any of the transmissions are dropped due to collisions with an Msg3 transmission. In addition, co-existence of TTI bundling and UL semi-persistent scheduling (SPS) for TDD DL/UL configurations is provided using SPS intervals which are multiples of various fixed time periods.
Abstract translation: TTI捆绑包含在LTE通信中的Msg3传输。 使用保留的前导码组或预留的随机接入前导码传输机会组来指示用户设备（UE）对TTI绑定的Msg3的上行链路（UL）传输的需求。 即使由于与Msg3传输的冲突而导致任何传输丢失，UE也会传输针对TTI束内传输的相同冗余版本。 此外，使用作为各种固定时间段的倍数的SPS间隔来提供用于TDD DL / UL配置的TTI绑定和UL半永久调度（SPS）的共存。

Abstract: Devices and methods for determining timing offsets between wireless devices are provided. One method includes transmitting, from a first device, a request for timing data to first user equipment and receiving a response. The timing data is indicative of a frame timing associated with a reference time for both the first device and a second device. The method further includes determining a timing offset between the frame timing for the first device and a frame timing for the second device based on the timing data. Another method includes receiving a reference time from a timing reference device, applying a timestamp to frame timing data for the first device, receiving frame timing data from the second device time-stamped based on the reference time, and comparing the timing data to determine a time offset between the devices.
