OBSS_PD and TxPower, similarly that we don’t need to specify the MCS selection algorithms. Yusuke Tanaka When a HE STA lowers the transmission power based on OBSS-PD, the transmission may not be heard by another STA in the BSS and it could cause inter-BSS collision more than regular transmission. Define a mechanism to adjust RTS threshold based on modified transmission power or OBSS-PD levels. Rejected – if HE STAs decides to lower its TxPower, it takes such risk and need to take that into account in its algorithm to set its TxPower.
