Abstract: Techniques are described for wireless communication. A first method includes receiving from a base station an indication of a set of one or more uplink interlaces of an unlicensed radio frequency spectrum band allocated for a sounding reference signal, and transmitting the sounding reference signal for a user equipment (UE) over the indicated set of one or more uplink interlaces of the unlicensed radio frequency spectrum band. A second method includes receiving an indication of an interlace of an unlicensed radio frequency spectrum band allocated for a physical uplink control channel (PUCCH) transmission, and transmitting a scheduling request and a buffer status report over the indicated interlace.

Abstract: Techniques are described for wireless communication. One method includes winning a contention for access to an unlicensed radio frequency spectrum band, transmitting a request message upon winning the contention for access to the unlicensed radio frequency spectrum band, and receiving a response message over the unlicensed radio frequency spectrum band. The request message is transmitted by a user equipment (UE) on an enhanced physical random access channel (ePRACH), to access a cell that operates in the unlicensed radio frequency spectrum band. The response message is received in response to transmitting the request message.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with specifying a traffic-to-pilot (T/P) ratio per subframe and/or resource block to allow a base station to transmit over the subframes and/or resource blocks using varying transmit powers. In one example, a device communicating with the base station can receive a plurality of T/P ratios each related to a power used by the base station to transmit over one of a plurality of carriers in a specific subframe or resource block, determine a power of a reference signal received from the base station over a carrier of the plurality of carriers, and process a data signal received over the carrier within the specific subframe or resource block based in part on applying, to the power of the reference signal, a T/P ratio of the plurality of T/P ratios corresponding to the carrier.

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 provided for combining different types of reference signals. A wireless communications network may be configured to allow a user equipment (UE) to combine multiple demodulation reference signals (DM-RSs) to support demodulation of a physical downlink shared channel (PDSCH), and/or other downlink transmissions, transmitted from a base station to the UE. The base station may provide explicit signaling that reference signals transmitted in two or more transmission time intervals may be combined, or a determination that reference signals transmitted in two or more transmission time intervals may be combined may be made implicitly based on system configuration and previous transmissions. Based on the explicit signaling and/or implicit determination, a UE may combine reference signals included in each of two or more reference signals for use in demodulation of downlink transmissions.

Abstract: Techniques are described for wireless communication. A first method may include inserting, in a first transmission using a first radio access technology (RAT), a channel occupancy identifier for a second transmission using a second RAT. The first method may also include transmitting the first transmission having the channel occupancy identifier over an unlicensed radio frequency spectrum band.

The channel occupancy identifier may be received over an unlicensed radio frequency spectrum band. The second method may also include decoding the channel occupancy identifier to identify a backoff period, and refraining from accessing the unlicensed radio frequency spectrum band using the first RAT based at least in part on the identified backoff period.

Abstract: Techniques are described for wireless communication. A first method includes receiving a primary synchronization signal (PSS) from a base station over an unlicensed radio frequency spectrum band. The PSS may be received on adjacent orthogonal frequency division multiplexing (OFDM) symbols of a first subframe of a downlink transmission. A user equipment (UE) may be synchronized with the base station based at least in part on the received PSS. A second method includes receiving a channel usage indicator over an unlicensed radio frequency spectrum band, and determining at least one OFDM symbol to monitor based on a time associated with the received channel usage indicator. A PSS may then be received from a base station over the unlicensed radio frequency spectrum band during the determined at least one OFDM symbol, and a UE may be synchronized with the base station based at least in part on the received PSS.
