Abstract: Methods, systems, and devices for wireless communication are described. A base station may perform an access procedure to obtain access to a shared radio frequency spectrum band during a measurement window and generate a synchronization signal (SS) burst comprising a plurality of SS blocks. The base station may perform a beam sweeping first transmission of the SS burst over the shared radio frequency spectrum based at least in part on the access procedure. In the first transmission or a second transmission, the base station may transmit at least one of a first indication of a time of access to the shared radio frequency spectrum band with respect to the measurement window, a second indication of a transmission beam associated with the SS block, and a third indication of a quantity of remaining SS blocks from the plurality of SS blocks to follow the SS block in the measurement window.

Abstract: Various aspects described herein relate to communicating using dynamic uplink and downlink transmission time interval (TTI) switching in a wireless network. A notification can be received from a network entity of switching a configurable TTI from downlink communications to uplink communications. The configurable TTI can be one of a plurality of TTIs in a frame structure that allows dynamic switching of configurable TTIs between downlink and uplink communications within a frame. Additionally, uplink communications can be transmitted to the network entity during the configurable TTI based at least in part on the notification.

Abstract: Suppression of serving cell transmissions directed to second-served UEs may improve channel estimation of a serving cell or a neighbor cell. This may include using scheduling information for second-served UEs to suppress serving cell signals intended for second-served UEs having overlapping MIMO transmissions. Alternatively, this scheduling information may aid in suppressing a serving cell signal for a second-served UE to improve channel estimation of a neighbor cell. Various embodiments described herein, include implementations and techniques to aid channel estimation, and signal scheduling information to a first-served UE to aid in suppression of serving cell signals for second-served UEs.

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.

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.

Abstract: Techniques are described for wireless communication. A first method may include receiving at a user equipment (UE) over an unlicensed radio frequency spectrum band an indication of a time window associated with a transmission of a synchronization signal, and monitoring the unlicensed radio frequency spectrum band during the time window to receive a synchronization signal from a base station. A second method may include transmitting an indication of a time window associated with a transmission of a synchronization signal; performing a plurality of clear channel assessments (CCAs) on an unlicensed radio frequency spectrum band during the time window; and transmitting the synchronization signal over the unlicensed radio frequency spectrum band at a transmission time during the time window. The transmission time may be based at least in part on a result of at least one of the CCAs.
