    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: Aspects of the present disclosure provided techniques that for wireless communications by a user equipment (UE). An exemplary method, performed by a UE, generally includes obtaining a first system information message from a wireless network configured to utilize Multimedia Broadcast multicast service Single Frequency Network (MBSFN) subframes and non-MBSFN subframes, determining, based on the first system information message, a first set of valid subframes and a first set of non-MBSFN subframes, obtaining a second system information message from the wireless network based on the first set of valid subframes and the first set of non-MBSFN subframes, and accessing the wireless network based on the first system information message and the second system information message.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adjust control overhead assumptions when reporting a channel state indictor (CSI). A base station may configure resource block (RB) sets for the UE by radio resource control (RRC) signaling. The UE may assume that the RB sets as configured are assigned for control information. When the UE reports wideband CSI, it may be assumed that the resources for an RB set are not available for data transmission. Any portion of a band configured for the UE overlapping with an RB set may be considered unavailable for data transmission. The UE may then calculate CSI based on the updated control overhead assumption. In other examples, the UE may make a worst-case assumption for control overhead. In some cases, the UE may assume there is no control overhead.

    Abstract: Various aspects described herein relate to techniques for managing resource allocation in wireless communications. In an aspect, the method includes identifying a system bandwidth for communications, identifying a downlink control information (DCI) format, determining one or more resource indication values (RIVs), and performing resource allocation based on the identified system bandwidth, the identified DCI format, and the one or more determined RIVs. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.
