IEEE 802.15.4-2020, Section 15: HRP UWB PHY

For HRP UWB the symbol period is derived from the preamble symbol period (T_psym), see section 11.3, table 11-1 and section 15.2.5, table 15-4 (confirmed in IEEE 802.15.4z, section 15.1). Choosing among those periods cannot be done based on channel page and channel alone. The mean pulse repetition frequency must also be known, see the 'UwbPrf' parameter of the MCPS-DATA.request primitive (section 8.3.2, table 8-88) and the preamble parameters for HRP-ERDEV length 91 codes (IEEE 802.15.4z, section 15.2.6.2, table 15-7b).
