Publication number: 20200367171Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to employ a discretionary on mode (e.g., powering receiver circuitry) in order to conserve power during discontinuous reception. The UE may discretionarily cut down an on time duration by delaying wake-up (e.g., powering on receiver circuitry) or by sleeping (e.g., powering down receiver circuitry) during portions of an on duration. The UE may also discretionarily skip one or more on durations. The UE may use hybrid automatic repeat request retransmissions to receive information that may be missed when sleeping during a configured on duration. The UE may evaluate one or more conditions in order to determine whether to employ a discretionary on mode. For example, the UE may determine to conserve power based on one or more of a data traffic type, a battery level, a channel condition, a retransmission policy, or physical layer activities.Type: ApplicationFiled: April 24, 2020Publication date: November 19, 2020Inventors: Shiau-He Tsai, Zae Yong Choi, Raghu Narayan Challa, Alexei Yurievitch Gorokhov, Jafar Mohseni
