Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a discontinuous reception (DRX) short cadence value that corresponds to a number of Hertz (Hz). The UE may sleep as part of a DRX cycle. The UE may wake up, starting at a subframe, based at least in part on the DRX short cadence value and a subframe identifier of the subframe. Numerous other aspects are described.

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.

The client device may monitor downlink data packets of a client software application operating on the client device to detect trigger events.

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: A method of wireless communication, by a user equipment (UE), includes receiving, from a base station, a medium access control-control element (MAC-CE) including an offset change command. The method also includes adjusting an offset within a periodic pattern based on the offset change command. A method of wireless communication, by a base station, includes detecting a misalignment between an arrival time of data relative to a periodic pattern. The method also includes transmitting, to a user equipment (UE), a medium access control-control element (MAC-CE) including an offset change command to adjust an offset within the periodic pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A base station and a user equipment (UE) may communicate in a wireless communications system. The base station may select a first bandwidth part from a plurality of bandwidth parts, the first bandwidth part having a bandwidth size corresponding to a traffic burst size for application data traffic within a time period. The UE may determine the bandwidth size using one or more parameters and indicate the bandwidth size to the base station. Additionally or alternatively, the base station may determine the bandwidth size using the one or more parameters. The base station may transmit, to the UE, a control signal indicating the first band-width part having the bandwidth size. The base station may schedule transmission of the application data traffic using the first bandwidth part and communicate the application data traffic with the UE using the first bandwidth part.

Abstract: Aspects relate to switching between different search space set groupings. A base station (BS) may send an indication to a user equipment (UE) to instruct the UE to switch from a first search space set grouping (SSSG) to a second SSSG. For example, the BS may send this indication after the BS transmits a first data burst to the UE. In some examples, the UE may then switch back to the first SSSG upon expiration of a timer. For example, the BS may configure the UE with a timer value (e.g., an absolute value, a relative value, or an indication thereof) that the UE may use to determine when to switch back to the first SSSG to receive a second data burst from the base station. In some examples, the UE may switch back to the first SSSG based on a discontinuous reception duration.

Abstract: Methods, systems, and devices for wireless communication are described. A network node may determine a first time location associated with a peak in data traffic for multiple devices in communication with a communications network including the network node. The network node may determine a second time location for the peak in the data traffic for a subset of the devices based on a threshold for an overall peak in data traffic for the multiple devices. The network node may transmit a signal that indicates the second time location for the peak in the data traffic for the subset of devices. The network node may communicate the data with the subset of devices based on the signal indicating the second time location.

The base station may receive the at least one UL transmission including the UL data, identify timing information, and calculate an UL delay based at least in part on the timing information from the UE. The timing information may be communicated in at least one of a PDCP protocol data unit (PDU) header or a medium access control (MAC) control element (CE) (MAC-CE).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE has received, from a network, a sufficient quantity of protocol data units (PDUs) to decode a frame. Accordingly, the UE may indicate, to the network, that the UE has decoded the frame.

Accordingly, the UE may refrain from transmitting one or more additional PDUs associated with the frame. Additionally, or alternatively, the UE may receive, from the network, an indication to disable some feedback to the network. Accordingly, the UE may refrain from transmitting one or more feedback signals based at least in part on the indication. Numerous other aspects are described.
