Abstract: Methods, systems, and devices for wireless communications are described. A network may configure one or more devices with a timer. The timer may define a threshold amount of time a receiver in a radio link control (RLC) acknowledgement mode (AM) is to wait for and continue to request retransmission of a missing RLC packet data unit (PDU) through automatic repeat request (ARQ) mechanisms. The receiver may detect a missing PDU, and may initiate two timers: a first timer defining how long the receiver is to request and monitor for the missing first PDU, and a second timer defining an amount of time before requesting retransmission of the first PDU. Upon expiration of the second timer, the receiver may transmit a request for retransmission of the first PDU. Upon expiration of the first timer, the receiver may forward all other sequentially received PDUs to higher layers for decoding.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an energy harvesting (EH) device may receive a discontinuous reception (DRX) configuration that indicates a DRX on-duration for data communication and an EH configuration that indicates a reserved EH duration during which the first device harvests energy and does not transmit or receive data. The DRX on-duration and the reserved EH duration may be part of a periodic cycle. The EH device may perform data communication during the DRX on-duration. The EH device may switch one or more antennas of the first device to an EH mode and perform EH during the reserved EH duration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to transmit a physical uplink shared channel (PUSCH) occasion skipping uplink control information (UCI) on more than one transmit occasion of a configured grant (CG). For example, the PUSCH occasion skipping UCI may be associated with a priority, and the UE may multiplex the PUSCH occasion skipping UCI with a PUSCH transmission when the UE does not identify another UCI with a higher priority than the PUSCH occasion skipping UCI to multiplex with the PUSCH transmission. In some examples, the priority of the PUSCH occasion skipping UCI may decrease over time (e.g., with each successive slot). In some examples, the UE may identify a gap period, and may transmit a new PUSCH occasion skipping UCI when the gap period has passed.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network entity may receive, from a second network entity, configuration information indicating multiple physical random access channel (PRACH) preamble configurations that are associated with respective cyclic shifts. The first network entity may transmit, to the second network entity, a random access communication that includes a PRACH preamble in accordance with a PRACH preamble configuration of the multiple PRACH preamble configurations, the PRACH preamble configuration being selected based on timing information of the first network entity. Numerous other aspects are described.

Abstract: To more efficiently utilize resources, a UE may receive, from a base station, RRM measurement relaxation criteria for a stationary UE. The UE may skip one or more RRM measurements based on the RRM measurement relaxation criteria for the stationary UE.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive a first stage wakeup signal (WUS) indicating to monitor for a second stage WUS using a low power radio. For example, the first stage WUS may indicate whether to monitor one or more upcoming monitoring occasions for the second stage WUS using the low power radio. The UE may receive the second stage WUS based on receiving the indication included in the first stage WUS. The second stage WUS may indicate for the UE to activate a main radio to monitor for a control channel to receive data transmitted by the network entity. Based on receiving the second stage WUS, the UE may activate the main radio and receive data from the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a base station that indicates a multicast or broadcast wake up signal (WUS) format. The UE may receive a multicast or broadcast WUS from the base station during a WUS monitoring occasion of a connected mode discontinuous reception (C-DRX) cycle in accordance with the control signaling. The multicast or broadcast WUS may indicate upcoming transmissions for a set of multicast or broadcast services (MBSs). If, for example, the UE is subscribed to a first MBS from the set of MBSs and the multicast or broadcast WUS indicates an upcoming transmission for the first MBS, the UE may monitor for the upcoming transmission during an active duration of the C-DRX cycle. Otherwise, the UE may enter a sleep mode to conserve power.

Abstract: Methods, systems, and devices for wireless communications are described. Energy harvesting (EH)-capable devices may receive power from transmissions by other devices. The network may schedule a user equipment (UE) to provide an energy transfer transmission to an EH-capable device. The UE may be unable to perform the scheduled energy transfer transmission. A UE scheduled to perform an energy transfer transmission to an EH-capable device may transmit an indication to the network, the EH-capable device, or another UE that the UE will skip the scheduled energy transfer transmission. In response, the EH-capable device may not monitor for the scheduled energy transfer transmission, the network may schedule a different resource for an energy transfer transmission by the UE, the network may schedule a different UE to perform an energy transfer transmission to the EH-capable device, and/or another UE which received the indication may perform an energy transfer transmission to the EH-capable device.

Abstract: Method and apparatus for delay states having variable configurations. The apparatus transmits, to a network entity, a delay status report indicating an uplink delay detected by the UE, wherein the uplink delay is greater than a first threshold. The apparatus switches, subsequent to transmitting the delay status report, from a first state configuration to a second state configuration that is different than the first state configuration for transmission of uplink data before a delay budget is exceeded. The second state configuration is a delay critical state and comprises a set of configurations for the transmission of the uplink data. The apparatus communicates, with the network entity, based on the second state configuration.

Abstract: Methods, systems, and devices for remote user equipment (UE) discovery and link establishment for reduced capability UE are described. In some examples, a relay UE may transmit one or more discovery messages associated with establishing a sidelink relay communication link between the relay UE and a remote UE having a reduced communication bandwidth capability relative to the relay UE. In such examples, the relay UE may perform a communication bandwidth configuration procedure with the remote UE based on the remote UE having the reduced communication bandwidth capability relative to the relay UE. In some examples, the relay UE and the remote UE may establish, in accordance with the communication bandwidth configuration procedure, the sidelink relay communication link between the relay UE and the remote UE using a reduced communication bandwidth that is less than a full communication bandwidth allocated for the relay UE.
