Abstract: A method and apparatus for uplink transmission by a user equipment (UE) includes receiving a first assignment for one or more beacon signals. The first assignment includes a first resource assignment and a first interlace assignment. The UE may determine that a size of a payload of an uplink transmission is less than a threshold. The UE may transmit the one or more beacon signals according to the first assignment in response to the determination. The one or more beacon signals increase bandwidth occupancy by the UE over a contention-based spectrum. Additionally, the UE may receive a second assignment for the payload of the uplink transmission. The second assignment includes a second resource assignment and a second interlace assignment. The UE may transmit the payload of the uplink transmission according to the second resource assignment on the second interlace assignment.

Abstract: The disclosure provides for control plane measurements in a wireless device. The wireless device may perform, on signals received over an unlicensed spectrum across multiple sub-frames, radio resource management (RRM) measurements of a cell. The wireless device may identify one or both of a first subset of the RRM measurements associated with a first subset of the sub-frames including opportunistic transmissions and a second subset of the RRM measurements associated with a second subset of the sub-frames including guaranteed transmissions. The wireless device may determine one or more RRM measurement values based on one or both of the first subset of the RRM measurements and the second subset of the RRM measurements. The wireless device may similarly perform radio link management (RLM) measurements and determine RLM measurement values based on the first and second subsets. The wireless device may also use timers for uplink transmissions to detect radio link failures.

Abstract: Certain aspects of the present disclosure generally relate to techniques for connectionless access by a wireless device. Such connectionless access may allow for the transmission of data without the overhead associated with establishing conventional connected access (e.g., radio resource control (RRC) connection) to a network. As a result, a device with relatively little data to transmit, such as a machine type communications (MTC) device, may be able to efficiently exit an idle mode, transmit the data during a connectionless access, and subsequently return to idle mode in a shorter period of time than conventional methods.

Abstract translation: 本公开的某些方面通常涉及无线设备无连接访问的技术。 这种无连接访问可以允许数据传输，而不需要与网络建立常规连接的接入（例如，无线电资源控制（RRC）连接）相关联的开销。 结果，诸如机器类型通信（MTC）设备的具有相对较少数据传输的设备可能能够有效地退出空闲模式，在无连接访问期间传送数据，并且随后在 比传统方法更短的时间。
