21 * OpenThread specific capabilities of ieee802154 driver.
30 /** Capability to support CST-related features.
32 * The CST-related features are described by "Specification changes for Thread-in-Mobile"
33 * Draft version 1, July 11, 2024. The CST allows to transmit a frame with CST Phase and
34 * CST Period IEs as described by chapter 4.6.6.1 of the Thread-in-Mobile specification
36 * a frame to be transmitted that contains placeholders where the CST Phase and CST Period
37 * are to be placed. The implementation of a driver is responsible for injecting
55 * 1 + max_extra_cca_attempts CCAs performed back-to-back.
57 * This mode is a non-standard experimental OpenThread feature. It allows transmission
58 * of a packet within a certain time window.
60 * When the first CCA reports an idle channel then the first symbol of the packet's PHR
65 * max_extra_cca_attempts will be done until one of them reports an idle channel and
66 * the packet is sent out or the max number of attempts is reached in which case
69 * The timing of these additional CCAs depends on the capabilities of the driver
73 * can calculate the latest point in time (T_txmax) that the first symbol of the scheduled
76 * T_maxtxdelay = max_extra_cca_attempts * (aCcaTime + T_recca) - T_recca + T_ccatx
79 * See IEEE 802.15.4-2020, section 11.3, table 11-1 for the definition of aCcaTime.

109 * When a frame containing CST Period IE is about to be transmitted by a driver,

121 * the value of this configuration parameter parameter, the time of transmission
125 * the network subsystem's local clock at which a TX frame's end of SFD
126 * (i.e. equivalently its end of SHR, start of PHR) is expected to be transmitted
136 * see IEEE 802.15.4-2020, sections 7.4.2.2 and 7.4.4.30.
