Abstract: A method and apparatus for uplink transmission by a user equipment (UE) includes receiving an uplink grant for data transmission in a subframe on an uplink channel, wherein the uplink grant includes an assignment to a resource block. The UE determines a resource block for sending a channel usage beacon signal (CUBS) over a contention-based spectrum based on the assignment included in the uplink grant. The CUBS reserves the uplink channel for the data transmission by indicating that the UE is sending the data transmission in a later subframe according to the assignment. The UE transmits the CUBS in a preceding subframe on the resource block in response to performing a successful clear channel assessment on the uplink channel, the preceding subframe directly preceding the subframe for the uplink data transmission.

Abstract: Certain aspects relate to methods and apparatus for latency reduction for UEs in a RRC connected mode. During contention-based uplink access by groups of UEs within a subframe, an eNB may decode the received uplink transmission based, at least in part, on the assigned group of resources assigned to the UE and used for transmission. Additional orthogonalization techniques such as reduced TTI size can be used to reduce collisions among different users performing contention-based transmissions. Furthermore, when the eNB fails to successfully decode the uplink transmission, the eNB may identify the UE that sent the uplink transmission based on a detected reference signal and may transmit an uplink assignment to the identified UE.

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: A method of wireless communication includes receiving position location reference signals (PRSs) from multiple remote radio heads (RRHs) and a macro eNodeB having a same physical cell identity (PCI). Each PRS is a same PRS. Additionally, the PRSs from the multiple RRHs are received on subframes that are different from subframes used by the macro eNodeB. Furthermore, each PRS does not indicate a source of transmission. The method also includes determining a time difference between the received PRSs.

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: Techniques for mitigating data loss during autonomous system information (SI) reading by a user equipment (UE) are described. For autonomous SI reading, the UE may autonomously determine when to read system information from neighbor cells and may not inform a serving cell. In one design, the UE may autonomously select a SI reading gap for reading system information from a neighbor cell. During the SI reading gap, the UE may suspend reception of downlink transmission from the serving cell, receive system information from the neighbor cell, and maintain capability to transmit on the uplink to the serving cell. In one design, the serving cell may determine SI reading gaps autonomously selected by the UE for reading system information from neighbor cells. The serving cell may communicate with the UE by accounting for the SI reading gaps of the UE, e.g., may suspend communication with the UE during the SI reading gaps.

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.
