    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an autonomous uplink (AUL) transmission to a base station using a configured resource set, the AUL transmission comprising reference signals and data signals. The UE may determine whether a response signal was received from the base station in response to the AUL transmission. The UE may determine whether the response signal indicates that the base station received the reference signals, or the reference signals and the data signals. The UE may select an uplink transmission scheme to use for subsequent transmissions to the base station, the selected uplink transmission scheme based at least in part on the determination of whether the response signal was received from the base station and whether the response signal indicates that the base station received the reference signals or the reference signals and the data signals.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure a physical channel such as a narrowband physical broadcast channel (NPBCH) to supplement (e.g., or as an alternative to) reference signal measurements when determining a received signal measurement, such as a received signal strength or received signal quality of a cell. A base station may transmit an indication to a UE that identifies the frequency at which a portion of NPBCH transmissions (e.g., reserved fields of a master information block (MIB)) is expected to change from one NPBCH transmission to another. The UE may adjust its utilization of NPBCH for determining the received signal measurement based on the indication. Further, the UE may communicate with the cell based on the determination of the received signal measurement, which are based on the indication.

    Abstract: A method of wireless communication includes receiving, by a user equipment (UE) from a base station, a trigger for aperiodic sounding reference signal (SRS) transmission for a group of component carriers (CCs), and selecting for transmission, by the UE and in response to the trigger, one or more SRS resource sets for each CC of the group of one or more CCs. At least one CC has multiple SRS resource sets configured. The UE transmits, to the base station, an SRS on each CC of the group of CCs based on the selecting. Another method of wireless communication includes transmitting, by a base station to a UE, a trigger for aperiodic SRS transmission for a group of CCs. At least one CC has multiple SRS resource sets configured for the UE. The base station receives, from the UE, one or more SRS on each CC of the group of CCs.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, for a base station, a configuration message indicating a set of random access resources associated with monitoring by a relay node. The UE may transmit a random access message using the random access resources to the relay node and a timing advance associated with uplink data transmissions by the UE. The UE may then communicate with the base station via the relay node based on the random access message. In some examples, a UE may monitor for a relay reference signal from a relay node. The UE may determine a signal strength and a timing of the relay reference signal. The UE may determine whether an RSRP satisfies a threshold receive power, and may determine whether the timing of the relay reference signal is less than a timing threshold. The UE may transmit a downlink relay request to the base station to initiate relay communications.

    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may provide for efficiently triggering a handover at a user equipment (UE) from a source cell to a target cell. The UE may receive, at a first time period, a first control message including a configuration of a target cell to use at a second time period for performing a handover procedure from a source cell to a target cell. The UE may then receive, at the second time period, a second control message triggering the UE to perform the handover procedure from the source cell to the target cell. The UE may use the configuration of the target cell received in the first control message to perform a handover procedure from the source cell to the target cell at the second time period in response to receiving the second control message.
