Publication number: 20250071681Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, one or more control signals indicating information associated with a set of occasions for a transmission time interval (TTI) corresponding to a low power operation mode of the UE. For example, the set of occasions may include one or more of a wake up signal (WUS) monitoring occasion, a synchronization signal block (SSB) occasion, a channel state information (CSI) reporting occasion, and a discontinuous reception (DRX) on duration occasion. The UE may determine whether to skip the WUS monitoring occasion based on a respective duration and a respective start time for each occasion of the set of occasions associated with the information indicated by the one or more control signals.Type: ApplicationFiled: August 21, 2023Publication date: February 27, 2025Inventors: Heechoon LEE, Zae Yong CHOI, Scott Hoover, Joshua Tennyson MACDONALD, Prem Swaroop KADAVAKUDURU, Pawneet SINGH, Manikandan CARNAGARIN

Publication number: 20240340792Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information indicating a wake-up signal (WUS) configuration associated with a discontinuous reception (DRX) cycle, wherein the WU'S configuration indicates one or more WUS occasions. The UE may identify one or more conditions. The UE may refrain from monitoring at least one WUS occasion, from the one or more WUS occasions, based at least in part on the identification of the one or more conditions.

Publication number: 20240306247Abstract: Apparatus, methods, and computer-readable media for facilitating multi-tasking and smart location selection during connected-mode discontinuous reception (CDRX) mode are disclosed herein. Example techniques disclosed herein enable a UE to perform multiple tasks during a same SSBS to reduce the number of wake-up SSBSs. For example, disclosed techniques enable a UE to perform RLM tasks and loop tracking tasks during a first SSBS and thereby reduce the number of wake-up SSBSs. In some examples, the UE may also perform the search task or the measurement task during the same first SSBS and, thereby, further reduce the number of wake-up SSBSs. Example techniques disclosed herein may also enable the UE to select which SSBS occurrences to wake-up for during the OFF duration of the CDRX cycle.Type: ApplicationFiled: May 16, 2024Publication date: September 12, 2024Inventors: Ting KONG, Jafar MOHSENI, Zae Yong CHOI, Yongle WU, Raghu Narayan CHALLA, Alexei Yurievitch GOROKHOV, Yong LI

Patent number: 12028807Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may wake up from a sleep mode of a discontinuous reception (DRX) cycle based on receipt of uplink data. The UE may determine if an elapsed time between a prior receipt of one or more reference signals and an uplink transmission to the base station after waking up from the sleep mode is less than a threshold time value. If the elapsed time is less than the threshold time value, the UE may transmit an uplink transmission associated with the received uplink data prior to receiving one or more reference signals that may be used to update transmission parameters for uplink transmissions. If the elapsed time is at or above the threshold value, the UE may wait to receive the one or more reference signals and update the transmission parameters prior to the uplink transmission.Type: GrantFiled: June 30, 2022Date of Patent: July 2, 2024Assignee: QUALCOMM IncorporatedInventors: Arnaud Meylan, Paolo Minero, Zae Yong Choi, Scott Hoover, Zhong Fan, Amir Aminzadeh Gohari

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

Patent number: 9456426Abstract: A gain factor is used for calculating one transmit power relative to another transmit power. For example, in UMTS high speed uplink packet access, a gain factor called ?ed is employed for transmission associated a given enhanced transport format combination indicator (E-TFCI). Conventionally, a gain factor to be used for a given E-TFCI can be determined via interpolation between two of the reference E-TFCIs to reduce signaling overhead. However, certain network configurations may result in one or more of the reference E-TFCIs that could be otherwise be used according to conventional techniques being outside of a valid range. In the event such a sub-optimal configuration occurs, interpolation and/or extrapolation schemes based on at least one reference E-TFCIs that is within and/or or is not within the valid range are used to calculate a gain factor for a given E-TFCI.Type: GrantFiled: May 23, 2014Date of Patent: September 27, 2016Assignee: QUALCOMM IncorporatedInventors: Ambarish Tripathi, Vaishakh Rao, Yi Zhang, Liangchi Hsu, Zae Yong Choi
