Abstract: Wireless communications systems and methods related to full-duplex cooperative communication by a first device tethered with a second device communicating with a third device. With the tether, one device between the first device and the second device is designated or selected as a transmitter, and the other device as a receiver. In full-duplex operation, the transmitter may transmit outgoing data concurrent to the receiver receiving incoming data. In an example, one of the first and second devices may have a modem that is used to control the full-duplex communication. The modem controls both transmission and reception. In another example, both devices may have a modem. Each modem may assume responsibility for part of the full-duplex communication by performing some processing before either shipping received data, or transmitting outgoing data. The amount of processing may be split at a link layer. Interference cancellation may mitigate interference from full-duplex operation.

Abstract: Aspects of the present disclosure provide techniques and apparatus for multiple physical resource block (PRB) operations for narrowband (NB) systems, such as NB internet-of-things (IoT). In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE), which may be an NB-IoT device. The method generally includes performing a cell search based on one or more signals received in an anchor RB within a set of RBs available for narrowband communications with a base station (BS); determining a location of at least one additional RB available for the narrowband communications with the BS based on an indication received in the anchor RB; and performing narrowband communications with the BS using at least one of: the anchor RB or the at least one additional resource block.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives, by a user equipment (UE) during a first subframe, an indication of a dynamic uplink/downlink (UL/DL) subframe configuration. The apparatus determines an uplink hybrid automatic repeat request (HARQ) timing based on an uplink reference subframe configuration and at least one of the dynamic UL/DL subframe configuration or a downlink reference subframe configuration. The apparatus selects an uplink subframe for communication based on the determined uplink HARQ timing.

Abstract: Certain aspects of the present disclosure propose techniques for transmission time interval (TTI) bundling for physical downlink shared channel (PDSCH) in long term evolution (LTE). According to certain aspects a method is provided for wireless communications. The method may be performed, for example, by a user equipment (UE). The method generally includes identifying a transmit time interval (TTI) bundle comprising a subset of subframes from a set of subframes for transmitting data on a physical downlink shared channel (PDSCH) and receiving the data on the PDSCH in the subset of subframes.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a user equipment (UE) may be configured to receive a control message scheduling a multicast transmission, and the UE may identify an open loop power control parameter for transmitting acknowledgment feedback responsive to the multicast transmission. The identification of the open loop power control parameter may be based on the transmission being multicast to a plurality of UEs, and in some cases a UE may identify an open loop power control parameter that is different than an open loop power control parameter associated with feedback responsive to unicast transmissions. In various examples, open loop power control parameters may correspond to respective feedback resources (e.g., according to a configuration for a set of open loop power control parameters), or to respective physical resource indicators (e.g., as signaled in downlink control information).

Abstract: Methods, systems, and devices for wireless communications are described. These wireless communications may include channel estimation procedures between communicating devices such as a base station and user equipment (UE). For example, the UE may receive, from the base station, a resource grant triggering a given reference signal configuration. Based at least in part on the type of reference signal configuration, the UE (e.g., and the base station) may determine a timing offset relative to the resource grant. The UE may transmit (and the base station may receive) the reference signal based at least in part on the timing offset. In some cases, the reference signal may be transmitted in a transmission opportunity of a set of transmission opportunities, where the set of transmission opportunities is determined based at least in part on the reference signal configuration.

Abstract: Coordinated wireless communications using multiple transmission time intervals (TTIs) are described. Multiple TTIs may include a first TTI and a second TTI, the second TTI having a shorter duration than the first TTI. One or more parameters may be determined for communications using the first TTI and the second TTI. A first parameter of the determined parameters for the second TTI may be associated or linked with a corresponding parameter of the first TTI, and communications using the first TTI or the second TTI may be performed using the first parameter. Wireless network nodes using the first TTI may form a CoMP cooperating set, and wireless network nodes using the second TTI may for another CoMP cooperating set, and the first parameter may be applied to each of the CoMP cooperating sets.
