Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain forward error correction (FEC) information associated with an application data unit (ADU). The UE may adjust a packet data convergence protocol (PDCP) characteristic, a radio link control (RLC) characteristic, or a physical layer hybrid automatic repeat request (HARQ) characteristic for transmitting a packet associated with the ADU based at least in part on the FEC information. Numerous other aspects are described.

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: Wireless communication devices, systems, and methods related to mechanisms to implement improved interference tracking over time. A BS may transmit information to a UE that allows the UE to quantize channel measurements into interference states. The UE may transmit an interference change report as triggered by an event, such as an interference metric exceeding a threshold after quantizing into the interference states. This enables the system to capture and respond to abrupt changes. Further, the interference change report may include historic interference information. The UE may include statistics based on the historic interference information. The UE may further be triggered to transmit an interference change report in response to a BS requesting it, or in response to a configured period of time elapsing. The UE may further include MCS information predicted for one or more future time periods based on historic information, which the BS may use in scheduling.

Abstract: In an aspect, a UE may perform clock synchronization in accordance with a first network timing reference, such as a unicast network timing reference (UNTR) or a broadcast networking timing reference (BNTR). The UE may detect event(s) associated with a connection to a BS, which may trigger a switch between the UNTR and the BNTR for clock synchronization. In a further aspect, a communications device (e.g., UE or BS) may determine to transition a UE between the BNTR and UNTR for clock synchronization, and may perform one or more actions to facilitate the network timing reference transition.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to system information acquisition over bandwidth parts (BWPs) in communications system operating according to new radio (NR) technologies. In an exemplary method, a user equipment (UE) receives system information (SI) via a transmission in a downlink (DL) bandwidth part (BWP) of a system bandwidth and transmits, to a serving base station (BS) and in response to receiving the SI, an indication that the UE has completed SI acquisition.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may configure a mapping between a set of power states and a set of codepoints. The network entity may indicate the mapping to a user equipment (UE) via control signaling, such as a first control message. Each power state may correspond to a respective directional communication profile associated with the network entity, the UE, or both. The network entity may transmit a second control message to the UE to indicate a codepoint from the set of codepoints. The UE device may transition to a power state that corresponds to the codepoint (e.g., based on the mapping) in accordance with the second control message. In some examples, the network entity may indicate the codepoint in a field of the second control message associated with a search space set group (SSSG) switching indication.
