Abstract: System(s) and method(s) are provided for transmitting data code symbols and control code symbols spanning disparate transmission time intervals in the uplink. Data and control symbols that overlap in time-domain within a transmission time interval are multiplexed and transmitted employing resources scheduled for data transmission, whereas data and control code symbols that are not multiplexed are transmitted in respective allocated resources. Multiplexing in conjunction with localized and distributed resource scheduling preserves the single-carrier characteristics of a single-carrier frequency division multiple access system.

Abstract: Methods, systems, and devices for wireless communication are described. A receiving device may detect a signal associated with low latency transmissions and decode a non-low latency communication accordingly. The receiving device may receive an indicator from a transmitting device that indicates where and when low latency communications occur. The indication may specify frequency resources or symbols used by the low latency communication. The indicator may be transmitted during the same subframe as the low latency communication, at the end of a subframe, or during a subsequent subframe. The receiving device may use the indicator to mitigate low latency interference, generate channel estimates, and reliably decode the non-low latency communication. In some cases, the interfering low latency communication may occur within the serving cell of the receiving device; or the interfering low latency communication may occur in a neighboring cell.

Abstract: Techniques for supporting broadcast, multicast, and unicast services in a cellular system are described. A Node B may multiplex data for broadcast and multicast services and data for unicast services on radio resources available for transmission. The Node B may periodically send scheduling information used to determine the radio resources carrying the broadcast and multicast services. In one design, the Node B may time division multiplex the data for the broadcast and multicast services and the data for the unicast services. The scheduling information may convey time unit(s) used for each broadcast or multicast service. In another design, the Node B may map the data for the broadcast and multicast services to time frequency blocks. The scheduling information may (i) convey the time frequency block(s) used for each broadcast or multicast service or (ii) point to control information conveying the time frequency block(s) used for each service.

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: Systems and methods for uplink transmission scheduling are disclosed. A wireless device may monitor at least two downlink sub-frames for scheduling grants. The wireless device may receive a first uplink scheduling grant in one of the at least two downlink sub-frames for at least a first uplink sub-frame and receive a second uplink scheduling grant in another of the at least two downlink sub-frames for at least the first uplink sub-frame. The wireless device may perform an uplink transmission in the first uplink sub-frame based on one or both of the first uplink scheduling grant and the second uplink scheduling grant.

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: A system and method for hybrid FDM (frequency division multiplexing)-CDM (code division multiplexing) structure for single carrier control channels is provided. The hybrid FDM-CDM structure maximizes frequency diversity over the entire available bandwidth such that orthogonality between signals from users in a given cell is maintained. Thus, users in the given cell can transmit over a non-contiguous set of tones. Furthermore, the hybrid FDM-CDM structure maintains orthogonality of a pilot of users in different cells based on a despreading operation in the time domain.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE receives synchronization signals and an information block from a first base station. The information block includes information indicating whether the first base station is in a dormant state or an active state. The UE detects the first base station based on the received synchronization signals and on the information indicating whether the first base station is in the dormant state or the active state. The UE may receive, from a second base station, an indication of resources for detecting the first base station. The synchronization signals and the information block may be received in the indicated resources. The UE may move to the first base station from a second base station in a handoff from the second base station to the first base station.

Abstract: Methods, systems, and devices are described for wireless communication at a UE. A user equipment (UE) may receive a control signal from a base station on resources of a first narrowband region. The UE may then identify a second narrowband region based on the control signal. In some cases a broadband carrier may be divided into an indexed set of narrowband regions, and the UE may identify an index using information contained in (implicitly or explicitly) in the control signal. The UE may communicate with the base station on resources of the second narrowband region. For example, a UE may receive a system information block (SIB) or a paging message, and perform a random access procedure using narrowband resources selected based on the SIB or paging message.
