A method for adjusting communication symbol sub-carrier frequency spacing based on a communication symbol priority at a communication beam transition location, comprising: identifying a communication beam transition location in time in a communication transmission time interval, TTI, where a communication beam transition will occur; and determining a configuration of a communication symbol that occurs one of immediately following the communication beam transition location and immediately preceding the communication beam transition location, at least partly based on the identified communication beam transition location and an identified high priority of the communication symbol, wherein a communication symbol having at least one of a demodulation reference signal (DMRS), channel state information-reference signal (CSI-RS), and a communication having a modulation and coding scheme having a high reliability requirement, is considered a high priority communication symbol, the configuration comprising; creating an extended guard period by reducing the sub-carrier frequency spacing of one of the communication symbols that occurs one of immediately following the communication beam transition location and immediately preceding the communication beam transition location, so that the sub-carrier frequency spacing for the symbol that occurs one of immediately following the communication beam transition location and immediately preceding the communication beam transition location is different than a sub-carrier frequency spacing for a symbol that does not one of immediately precede the communication beam transition location and immediately follow the communication beam transition location. identifying a communication beam transition location in time in a communication transmission time interval, TTI, where a communication beam transition will occur; and determining a configuration of a communication symbol that occurs one of immediately following the communication beam transition location and immediately preceding the communication beam transition location, at least partly based on the identified communication beam transition location and an identified high priority of the communication symbol, wherein a communication symbol having at least one of a demodulation reference signal (DMRS), channel state information-reference signal (CSI-RS), and a communication having a modulation and coding scheme having a high reliability requirement, is considered a high priority communication symbol, the configuration comprising; creating an extended guard period by reducing the sub-carrier frequency spacing of one of the communication symbols that occurs one of immediately following the communication beam transition location and immediately preceding the communication beam transition location, so that the sub-carrier frequency spacing for the symbol that occurs one of immediately following the communication beam transition location and immediately preceding the communication beam transition location is different than a sub-carrier frequency spacing for a symbol that does not one of immediately precede the communication beam transition location and immediately follow the communication beam transition location.
