Abstract: Various techniques are presented to improve phase tracking reference signal (PTRS) performance with respect to very high frequency communications. According to some embodiments, increased power boosting may be applied to improve PTRS performance, while still keeping power spectral density (PSD) within ETSI Broadband Radio Access Networks (BRAN) limits. In some cases, the power boosting may be semi-static and/or dynamic. In other embodiments, the improved performance may be achieved by dynamically changing time and/or frequency density of the PTRS. In other embodiments, a multi-port configuration may be used for the downlink PTRS. In other embodiments, one or more PTRS configurations may be determined per SCS and/or frequency band, e.g., based on traffic type, channel priority, parameters signaled in the slot format indication (SFI), etc. In other embodiments, common phase error (CPE) estimates may be obtained for those OFDM symbols without PTRS by interpolating the available PTRS estimates in the time domain.
