Abstract
Methods, systems, and devices for wireless communication are described. Pilot ratios (e.g., a ratio of pilot (or reference signal) resources to a total number of resources) may be adapted based on various properties associated with transmissions between wireless devices. For example, a wireless device (e.g., a user equipment (UE) or a base station) may use different transmission configurations for transmitting messages that include reference signals and data. Based on the transmission configuration, the wireless device may determine an adjustable pilot ratio based on the transmission configuration. In some cases, the adjustable pilot ratio may be explicitly signaled, or may be implicitly determined based on the transmission configuration. For example, a wireless device may transmit (or receive) an indication of the pilot ratio, or the wireless device may determine the pilot ratio based on a transmission configuration used for communicating with the other wireless device.
