Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, devices may implement transmission repetitions for transport blocks (TBs) to improve reception reliability. However, to support low latency, TBs may be transmitted in any transmission time interval (TTI) within a subframe. The systems may implement process to handle these TB repetitions. In some cases, a device may receive, during a TTI of a subframe, control information including an indication of transmission repetitions of a TB for a plurality of TTIs, identify a quantity of transmission repetitions of the TB based on the control information, and monitor for the transmission repetitions of the TB.

Abstract: In an aspect, while a mobile device is operating in a RRC_Idle State, an RRC_Suspended State, an RLF State and/or an RLF Recovery Procedure State, the mobile device may transmit a connection establishment message to a base station of a plurality of base stations. In an aspect, the connection establishment message includes information that indicates whether the mobile device has information associated with signals transmitted by one or more base stations of the plurality of base stations. The mobile device may initiate transmission of the information associated with the signals to the base station subsequent to establishing a security context for the connection between the mobile device and the base station. In some aspects, the mobile device may scramble the information associated with signals and transmit the information associated with signals to the base station prior to establishing a security context for a connection between the mobile device and the base station.

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: Certain aspects of the present disclosure relate to techniques for secondary cell (SCell) configuration signaling and activation procedures. For example, certain aspects provide a method for configuring a plurality of secondary cells of a base station for a user equipment. The method includes receiving, at the user equipment from the base station, a message including at least one configuration parameter applicable to the plurality of secondary cells. The method further includes configuring the user equipment for the plurality of secondary cells based on the at least one configuration parameter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first information element (IE) and a second IE, wherein the first IE indicates whether all UEs that do not support cell-specific reference signal (CRS) muting are barred from a carrier and the second IE indicates whether all UEs that support CRS muting are barred from the carrier; and selectively access the carrier based at least in part on at least one of the first IE or the second IE. In some aspects, a UE may determine whether the UE supports cell-specific reference signal (CRS) muting; and transmit, to a base station, a capability report that indicates whether the UE supports CRS muting. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may signal one or more emission limits for one or more different frequency bands, and two or more values for one of the emission limits may be provided. A first subset of user equipments (UEs) may be capable of aerial operations (e.g., unmanned aerial vehicles (UAVs) or drones) and may use a first value of the first emission limit and the second subset of UEs may not capable of aerial operations and may use a second value of the first emission limit. A UE status such as altitude or position, or transmission directivity may also be used to determine if the UE is to apply the first value or the second value for an emission limit of a frequency band.

Abstract: Methods, systems, and devices for wireless communications are described to enable a base station to configure additional reference signals, which may be referred to as configured reference signals, to include in a transmission to a user equipment (UE). The UE may transmit a report to the base station, indicating a UE capability for supporting configured reference signals, and the base station may configure a pattern for the configured reference signals. The base station may transmit an indication of the pattern to the UE, where the indication may include one or more characteristics associated with the configured reference signals. The base station may transmit the configured reference signals to the UE according to the pattern, along with one or more baseline reference signals, within an associated transmission. The UE may use the configured reference signals and the baseline reference signals to receive a transmission from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. that support preconfigured uplink resources (PUR) in wireless communications. A base station may communicate that support for PUR is available, and may allocate PUR resources to a user equipment (UE) based on requests from the UE. The UE may receive an indication that the base station supports PUR, such as via a system information block (SIB), determine to request PUR, and transmit a PUR request message to the base station. A PUR response from the base station may indicate configuration, or reconfiguration of PUR allocation for the UE that may be used for uplink transmissions, or release of the PUR allocation.
