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.
