Wireless access point control of discontinuous reception (DRX) parameters for user equipment (UE)
A wireless access point controls Discontinuous Reception (DRX) parameters for User Equipment (UE). The wireless access point wirelessly exchanges wireless communications with a plurality of UEs comprising High Power UEs (HPUEs) and non-HPUEs. The wireless access point determines a number of the HPUEs and determines a number non-HPUEs experiencing RF interference above an RF interference threshold. The wireless access point compares the number of non-HPUEs experiencing RF interference above the RF interference threshold to the number of HPUEs and when the number of non-HPUEs experiencing RF interference above the RF interference threshold exceeds the number of HPUEs, then the wireless access point modifies the DRX parameters for the HPUEs to a low DRX parameter setting. The wireless access point wirelessly transmits an instruction to the HPUEs indicating the modification of the DRX parameters for the HPUEs to the low DRX parameter setting.
