Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to reference signal design for communications with coverage enhancements and devices with limited communications resources, such as machine type communication (MTC) devices, enhanced or evolved MTC (eMTC) devices, and internet of things (IoT) devices. An example method generally includes determining a set of additional reference signals to transmit in a bundled transmission, based on a bundle length of the bundled transmission, and transmitting the bundled transmission, reference signals, and the additional reference signals, based on the determination.

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: Techniques are described for wireless communication. A method for wireless communication may include identifying interference at a first node operating in a shared radio frequency spectrum band. The interference may be caused by a second node operating in the shared radio frequency spectrum band. The second node may operate asynchronously to the first node in the shared radio frequency spectrum band. The method may also include adaptively enabling, based at least in part on the identified interference, a synchronization of the first node with at least a third node in the shared radio frequency spectrum band.

Abstract: Techniques are described for preempting resource allocations to one or more UEs in the event that delay sensitive data is received. A resource allocation of a number of symbols may be granted to a first user equipment (UE) for first associated data to be transmitted. Subsequently, data may be received for a second UE that is more delay sensitive than the first data. The resource allocation to the first UE may be preempted, and resources allocated to the second UE for the second data within a variable length transmission time interval (TTI) of the resource allocation to the first UE. UEs may monitor for preemption during transmissions to other UEs in order to receive new resource grants associated with the preempted resource grant. Whether a UE monitors transmissions for preemption may be determined based on a quality or service (QoS) of the UE.

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: Dual-thread feedback for non-orthogonal channels used in wireless communications systems is described. A first feedback thread may employ transmission strategy (TS) independent feedback and a second feedback thread may employ TS dependent feedback. The first feedback thread may include channel feedback from channel measurements (e.g., channel gain, noise covariance, etc.) and may be fed back periodically. A TS space may be determined that includes combinable TSs for UEs that may be grouped for non-orthogonal techniques, and one or more TS sets may be sent to the UEs. UEs may determine channel quality and/or other channel state information (CSI) for the TSs and report CSI for one or more TSs of the TS sets in a second feedback thread. Scheduling may be performed for transmissions to the UEs based on the feedback in the first and/or second feedback threads.

Abstract: Methods, systems, and devices are described for providing allocations and signaling for different types of communications within a wireless communication system. An eNB and/or a UE may be configured to operate within the wireless communication system using two or more different types of communications. The different types of communications may differ, for example, based on round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, a transmission time interval (TTI) for wireless transmissions, and/or duty cycle timing of wireless transmissions. Reserved resources within a system bandwidth may be identified for a first type of communications, and all or a portion of remaining resources within the system bandwidth may be allocated for other communications that may differ from the first type of communications based on, for example, RTT, TTI, and/or duty cycle timing.

Abstract: Techniques are described for wireless communication. A first method includes generating uplink control information at a wireless device, and transmitting the uplink control information over an interlace of a component carrier of an unlicensed radio frequency spectrum band. The interlace includes a plurality of non-contiguous concurrent resource blocks in the unlicensed radio frequency spectrum band, and at least two resource blocks in the interlace include different portions of the uplink control information. A second method includes generating uplink control information at a wireless device, and transmitting the uplink control information over an uplink control channel of an unlicensed radio frequency spectrum band. Resources of the uplink control channel are divided into a plurality of discrete dimensions and the uplink control information of the wireless device is transmitted over a number of the discrete dimensions allocated to the uplink control information of the wireless device.
