Abstract: Methods, systems, and devices for wireless communications in a multiple bandwidth part environment are described. In response to a serving beam failure in an active bandwidth part, the UE may determine a level of support provided by the active bandwidth part for a random access procedure, and may determine a contingency (e.g. fallback) bandwidth part that supports the random access procedure. In some cases, the UE may identify the contingency bandwidth as an initial bandwidth part used by the UE for a prior random access procedure. In some cases, the base station may send to the UE, an explicit indication of the contingency bandwidth part. In some cases, the UE may identify the contingency bandwidth part based on a reference signal. Upon determining the contingency bandwidth part, the UE may perform the random access procedure using the contingency bandwidth part.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives RSs from a base station. The UE determines, based on the RSs, a second CSI indicator indicating a first precoding configuration of the base station optimized to at least one of improve signal power or reduce interference in an elevation dimension. The UE determines, based on the RSs, a second CSI indicator indicating a second precoding configuration of the base station optimized to at least one of improve the signal power or reduce interference in an azimuth dimension. The UE transmits, to the base station, a first CSI report including at least the first CSI indicator.

Abstract: Methods, systems, devices, and apparatus for wireless communication are described that relate to transmission of a set of precoded reference signals, and using a physical resource group (PRG) size for the resources carrying the set of reference signals for channel estimation at a user equipment (UE). For example, a base station may apply a precoding matrix to a set of reference signals, and the reference signals may be configured on a set of resources. In such cases, the resources including these reference signals having a same precoding may be included in a PRG, and a size of the PRG may refer to a number of precoded reference signals for which the precoding is the same. Based on the received reference signals and the PRG size the UE may perform channel estimation based on the PRG size and transmit channel state information (CSI) to the base station.

Abstract: Aspects of the disclosure relate to a transmitting device, which may explicitly or implicitly signal the use of continuous precoding for a resource block (RB) cluster. For example, the transmitting device may implicitly indicate that continuous precoding is applied to an RB cluster by dynamically controlling one or more parameters of a transmission over those RBs. Further, when continuous precoding is applied to an RB cluster, the transmitting device may explicitly or implicitly signal the dynamic control over one or more transmission properties, with an aim to maximize the benefits of such continuous precoding. Other aspects, embodiments, and features are also claimed and described.
