Publication number: 20240138023Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a voice call. The UE may receive a configuration for a discontinuous reception (DRX) cycle indicating at least an ON duration and a DRX cycle duration. The UE may receive a configuration for a scheduling request (SR) indicating an SR period duration for transmitting an SR.

Patent number: 11968674Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message indicating a resource configuration for uplink and downlink transmissions. The UE may determine an uplink buffer threshold for a modem buffer of the UE based on the resource configuration. The UE may transmit, to the base station, a feedback request message requesting that the base station provide feedback for at least one previously transmitted uplink packet based on a comparison of an amount of previously transmitted uplink data and scheduled uplink data stored in the modem buffer relative to the uplink buffer threshold.

Publication number: 20240056976Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE starts a first timer (such as a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer), after sending an uplink (UL) data transmission to a network entity. The UE then starts a second timer (such as a DRX retransmission timer) when the first timer expires. The UE then determines whether to wake up or sleep for a duration of the second timer based on a prior block error rate (BLER).Type: ApplicationFiled: October 10, 2023Publication date: February 15, 2024Inventors: Leena ZACHARIAS, Arnaud MEYLAN, Reza SHAHIDI, Lan LAN, Qingxin CHEN, Farrukh RASHID, Zhibin DANG, Akshay KUMAR

Publication number: 20240048286Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) determine that at least one packet of a set of packets for a downlink message is unsuccessfully received at a radio link control (RLC) layer of the UE due to a specific situation of a set of specific situations and may transmit the NACK message based on the missing packet (s) on an as needed basis rather than waiting for a timer to expire (e.g., a fast NACK mechanism). In some examples, the specific situations may include the UE missing packets after a measurement gap, missing packets based on wake up latencies for a discontinuous reception mode of the UE, missing packets due to interference from reference signals transmitted by neighboring cells, missing packets due to the UE not decoding retransmissions that have a same redundancy version (RV) of a downlink message, or a combination thereof.Type: ApplicationFiled: February 11, 2021Publication date: February 8, 2024Inventors: Sitaramanjaneyulu KANAMARLAPUDI, Ling XIE, Hobin KIM, Leena ZACHARIAS, Wei LI
