Abstract: Systems and methods for discontinuous reception (DRX) adaptation in a wireless communication system are provided. A network entity may configure a user equipment (UE) with a long DRX cycle. Under certain conditions, additional short DRX cycles may be activated by the network entity so that data may be transferred before the next DRX active time. Multiple aspects are described wherein short DRX cycle parameters are communicated explicitly or implicitly to the UE. Short DRX cycle parameters may be included and/or indicated by bits in a downlink control information (DCI) or a Medium Access Control (MAC) Control Element (CE) command received by the UE during the long DRX active time.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sidelink channel access via a floating channel occupancy. In some aspects, a cellular device may operate within a proximity of one or more wireless fidelity (Wi-Fi) devices and may conditionally support a search space associated with a floating sidelink synchronization signal block (SSB). For example, if the cellular device detects that the Wi-Fi devices are precluding the cellular device from acquiring channel access or otherwise making it relatively more difficult for the cellular device to acquire channel access, the cellular device may enable or active a use of the search space associated with the floating sidelink SSB. If enabled or activated, the cellular device may transmit a floating sidelink SSB within the search space independent of slot boundaries upon a successful listen-before-talk (LBT) procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a new beam ready time that indicates a time at which a beam is to be ready for use in communicating with a base station. The beam may be activated by a downlink control information based beam activation command received by the UE. The UE may communicate with the base station using the beam after the new beam ready time. Numerous other aspects are provided.

Abstract: Techniques and apparatus for determining a transport block (TB) configuration and hybrid automatic repeat request (HARQ) acknowledgment (ACK)/negative acknowledgment (NACK) configuration for full duplex (FD) UE(s) are described. One technique involves receiving channel state information (CSI) report(s) from a UE operating in FD mode. At least one of a TB configuration or feedback type for a communication slot is determined based on the CSI report(s). The communication slot can include half duplex (HD) symbol(s) and FD symbol(s). An indication of at least one of the TB configuration or the feedback type is signaled to the UE. Another technique involves receiving, from a base station (BS), downlink data transmission(s) across a slot(s). A type of duplexing mode associated with each of the slot(s) is determined. The downlink data transmission(s) are acknowledged, based at least in part on the type of duplexing mode associated with each of the slot(s).

Abstract: Wireless communication devices, systems, and methods related to bundling of uplink communication signals under timing advance (TA) conditions are provided. For example, a method of wireless communication performed by a user equipment can include receiving, from a base station, a timing advance (TA), wherein the TA is scheduled to be implemented by the user equipment at a first time, the first time being after a start of a first uplink communication of a group of bundled uplink communications scheduled with phase coherence and before a start of a second uplink communication of the group of bundled uplink communications; determining whether to implement the TA at the first time or a second time, the second time being after transmission of the second uplink communication; and implementing the TA based on the determining.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a positioning entity receives motion state information associated with a user equipment (UE), the motion state information indicating constraints on a location of the UE relative to a moveable object with which the UE is associated, and estimates the location of the UE based on at least the motion state information.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipments (UEs) may transmit a sidelink indication signal including a sequence (for example, wakeup signal or go-to-sleep signal) for a receiving UE to determine whether to monitor for scheduling sidelink control information (SCI) messages in one or more sidelink discontinuous reception (DRX) on durations that overlap in time. The receiving UE may determine (for example, based on an initial value in the sequence, the resource on which the sequence was received, among other examples) a location of an on duration, and may perform a DRX operation (for example, may wake up or may go to sleep) during the on duration.

Abstract: A method for wireless communication by a user equipment includes receiving, from a network node, a first message configuring a group of inactivity timers including indicating a respective timer duration value for each inactivity timer of the group of inactivity timers. Each inactivity timer of the group of inactivity timers may be associated with a respective network power saving mode of a group of network power saving modes. The method also includes initiating a first inactivity timer of the group of inactivity timers with a respective timer duration value based on receiving a first downlink transmission from the network node or transmitting first uplink information to the network node. The method further includes enabling a radio resource control (RRC) state of a group of RRC states based on an expiration of the first inactivity timer.

Abstract: Disclosed are techniques for wireless position estimation of a user equipment (UE) involving one or more uplink (UL) relays. The UL relay(s) receives UL data communications from UEs, and relay the UL data communications to a serving network component (e.g., gNB) via a backhaul connection (wired or wireless). In an aspect, uplink relay(s) are selected by a network component for a position estimation session of a target UE. The uplink relay(s) measure UL SRS for positioning from the target UE, and report UL SRS measurement information to the network component and/or the serving network component.

Abstract: In a wireless access network, a false base station (FBS) may imitate a legitimate base station by repeating the transmissions of the legitimate base station at a higher power level such that one or more user equipment (UEs) synchronize with the FBS instead of the legitimate base station. The present disclosure provides a UE that detects an FBS. The UE may estimate a time of arrival of different multipath components of a downlink signal corresponding to a physical cell identity. The UE may determine an existence of FBS based on a difference between the times of arrival of two of the different multipath components exceeding a threshold amount of time. The UE may perform a mitigation operation in response to determining the existence of the FBS.
