Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first sounding reference signal (SRS) configuration, wherein the first SRS configuration indicates a number of antenna ports on which an SRS is to be transmitted. The UE may determine that the number of antenna ports indicated by the first SRS configuration exceeds an antenna capability of the UE. The UE may transmit one or more SRSs using a second SRS configuration based at least in part on determining that the first SRS configuration exceeds the antenna capability of the UE. Numerous other aspects are described.

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: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with one or more parameters to support blockage detection for beamformed communication. The UE may receive a set of reference signals via a receive beam of a beam pair. The UE may detect a condition associated with a measured signal quality of a reference signal of the set of reference signals relative to a filtered signal quality of the set of reference signals. The condition may, in some examples, correspond to a drop of the measured signal quality at least a threshold amount below the filtered signal quality for at least a threshold duration of time. The UE may delete one or more signal quality values from a measurement database of the UE based on detecting the condition. The one or more signal quality values may be associated with the beam pair.

Abstract: Certain aspects of the present disclosure provide techniques for power savings for reduced capability devices. A method that may be performed by a user equipment (UE) includes receiving a shared bandwidth part (BWP) configuration and a group common BWP configuration. The group common BWP configuration indicates a group common BWP shared by a group of UEs, including the UE, having one or more common capabilities or a common UE type. The method includes communicating using the group common BWP based on the group common BWP configuration.

Abstract: The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Abstract: Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described that provide for channel-bandwidth-attributed per-band user equipment capability reporting. A user equipment (UE) may determine a first and second set of physical layer capabilities associated with a first and second channel bandwidth, respectively. The UE may transmit a first and second UE capability report to the base station, where the capability reports may indicate the corresponding channel bandwidth and may include the UE physical layer capabilities. The UE may receive control information indicating a channel bandwidth from the base station and the UE may communicate with the base station according to the received control information.
