Abstract: Aspects relate to wireless communication where a master node (MN) or a secondary node (SN) may initiate a conditional addition of a primary secondary cell (PSCell) or a conditional change from one PSCell to another PSCell. Each candidate target PSCell may provide information to be used by the MN to generate a conditional PSCell addition (CPA) configuration or a conditional PSCell change (CPC) configuration that is sent to a user equipment (UE). This information may indicate an execution condition for each candidate target PSCell and/or radio bearers that each candidate target PSCell supports or does not support. An MN may modify a master cell group (MCG) configuration for a PSCell based on information received from a target SN with an secondary cell group (SCG) configuration for the PSCell. The MN may transmit a CPA or CPC configuration including the modified MCG configuration and the SCG configuration to the UE.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling and bandwidth part (BWP) adaptation for extended reality (XR). A method that may be performed by a user equipment (UE) includes obtaining an indication to change at least one of a minimum control-channel-to-data-channel delay or a bandwidth for receiving a first transmission on a BWP; changing the at least one of the minimum control-channel-to-data-channel delay to a new minimum control-channel-to-data-channel delay or the bandwidth on the BWP to a new bandwidth; and receiving the first transmission on the BWP using the at least one of the new minimum control-channel-to-data-channel delay or the new bandwidth of the BWP.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive discontinuous reception (DRX) configuration information identifying a slot or sub-slot granularity for transitioning from a non-monitoring state to a monitoring state, wherein the information identifies, for each slot or sub-slot, whether to operate in the non-monitoring state or the monitoring state; and transition from the non-monitoring state, wherein the user equipment (UE) is not performing monitoring, to the monitoring state, wherein the UE is performing monitoring, in accordance with the DRX configuration information. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive multiple transport blocks (TBs) representing an application data unit (ADU) from a base station. The base station may transmit an indication that the UE is to provide ADU level feedback. The UE may determine the ADU level feedback based on whether the ADU is successfully received and decoded or not. The UE may indicate the ADU level feedback for the TBs to the base station. The base station and the UE may communicate according to the ADU level feedback.

Abstract: Methods, systems, and devices for wireless communication are described. A device (e.g., a user equipment (UE) or a base station) may communicate (e.g., receive or transmit) a set of service data units (SDUs) of an application data unit (ADU). The device may be aware of the set of SDUs corresponding to the ADU based on an identifier in a header of the set of SDUs. The device may determine that an SDU of the ADU is absent and proactively transmit a signal based on identifying the absent SDU. Signaling ADU awareness between distributed units (DUs) and a centralized unit (CU) of a base station is described. The CU may indicate that a set of SDUs correspond to an ADU via a user plane interface. For example, a header associated with the interface may include one or more bits identifying the ADU in a payload corresponding to the header.

Abstract: A base station determines a window of time for arrival of uplink signals, wherein the window of time includes a start based on a first expected time of arrival for a first uplink signal from a first UE and an end based on a second expected time of arrival for a second uplink signal from a second UE. The base station detection detects a false base station, such as a L1 man-in-the-middle false base station, based on an uplink signal being received outside of the determined window of time for the arrival of uplink signals.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications entity, such as a user equipment (UE), a base station, a network core, or an application server, may identify a round-trip time (RTT) latency requirement that may pertain to a round-trip latency in wireless communications between the UE and the base station. The wireless communications entity may identify a one one-way directional delay budget that satisfies the RTT latency requirement for an application of an application server. The application server may be in communication with the UE via the base station. The wireless communications entity may modify a value of the one-way directional delay budget and transmit a message that is associated with the modified value of the one one-way directional delay budget.

Abstract: Apparatus, methods, and computer-readable media for facilitating detection of false base stations based on signal times of arrival are disclosed herein. An example method for wireless communication of a UE includes receiving a signal from each of one or more neighboring base stations. The example method also includes determining a system timing associated with the wireless communications network based on a respective time of arrival at which each signal is received from the neighboring base stations. The example method also includes receiving a signal from an FBS, the FBS signal being associated with a PCI different than the PCIs associated with the signals received from each of the neighboring base stations. Additionally, the example method includes identifying a presence of the FBS based on a difference between the system timing and a time of arrival at which the signal is received from the FBS.
