Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a user equipment (UE) and/or base station. In one aspect, the apparatus can determine to enter into a two-step RACH procedure in an RRC inactive state. The apparatus can also determine to transmit uplink data in a payload of a message A (MsgA) of the two-step RACH procedure. The apparatus can also transmit the MsgA of the two-step RACH procedure, the MsgA including the payload, the payload including at least the uplink data. Additionally, the apparatus can monitor for a MsgB of the two-step RACH procedure. The apparatus can also receive the MsgB of the two-step RACH procedure, where the MsgB includes a fallback indication including a fallback RAR. Further, the apparatus can retransmit the payload of the MsgA when the MsgB including the fallback indication is received.

Abstract: The aspects described herein are directed to measurement and reporting procedures of an apparatus (e.g., a low-tier user-equipment (UE) or a regular UE) when a bandwidth part (BWP) of the apparatus includes one or both of a first type of synchronization signal block (SSB) (e.g., a cell-defining (CD-SSB)) and second type of SSB (e.g., a non-cell-defining SSB (NCD-SSB)). The apparatus measures at least one of the first type of SSB that is periodically transmitted to a first group of UEs, a second type of SSB that is periodically transmitted within a time window to a second group of UEs, or both the first type of SSB and the second type of SSB for an operation based on a configuration of the operation, and performs the operation based on a measurement of at least one of the first type of SSB, the second type of SSB, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a device, such as a user equipment (UE), may establish a primary cell (PCell) connection and a secondary cell (SCell) connection which may trigger a power headroom (PHR) report and initiate a timer for PHR reporting based on the triggering. The UE may configure a bandwidth part (BWP) associated with the SCell connection to operate in a first dormancy state. The UE may receive an indication to configure the SCell BWP to operate in a second dormancy state and may switch the SCell BWP operations to the second dormancy state. The UE ay determine a status of the timer for PHR reporting and may determine whether to transmit a PHR report based on the status of the timer and the indication to switch the BWP operations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration, for a multicast broadcast service (MBS) single frequency network (SFN) area, indicating configuration information for one or more multicast traffic channels. The UE may receive, in accordance with the configuration, a physical downlink control channel (PDCCH) communication scheduling an MBS SFN data communication associated with a multicast traffic channel, of the one or more multicast traffic channels. The UE may receive the MBS SFN data communication via a physical downlink shared channel (PDSCH) that is associated with both SFN communications and unicast communications or that is associated with only MBS SFN communications. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive first information indicating a first discontinuous reception (DRX) configuration for a first group of cells and second information indicating a second DRX configuration for a second group of cells. The UE may receive third information configuring a wakeup signal (WUS) for the UE. The UE may receive fourth information indicating that the WUS applies to a set of groups of cells selected from the first group of cells and the second group of cells. The UE may receive the WUS based at least in part on the third information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a medium access control layer message indicating a set of mappings between a set of pathloss reference signals and one of: a set of physical uplink shared channel identifiers, or a set of sounding reference signal identifiers; receive downlink control information activating a mapping of the set of mappings; and perform a pathloss measurement using a pathloss reference signal identified by the activated mapping. Numerous other aspects are provided.

Abstract: Wireless communication devices, systems, and methods related to handling user equipment's (UE's) failure to receive a timing advance (TA) command from a base station during in a two-step random access procedure are provided. For example, a method of wireless communication can include transmitting a first random access channel (RACH) message (e.g., msgA); monitoring for a second RACH message (e.g., msgB) from the BS including a timing advance (TA) command; performing a hybrid automatic repeat request (HARQ) procedure on the second RACH message; and performing, when the HARQ procedure on the second RACH message fails, at least one of: starting a new RACH procedure or triggering a radio link failure (RLF).

Abstract: In a wireless network, a base station may transmit a paging early indication (PEI) to a user equipment (UE) before a paging occasion (PO) to indicate whether the UE should wake up to receive a page, which is more power-efficient than legacy paging reception. However, UEs may not universally support PEI. Furthermore, a UE lacking PEI support cannot realize the potential power savings offered by a PEI. Accordingly, a UE may transmit, to a base station, capability information indicating whether the UE supports a PEI, and the base station may configure paging reception for the UE based at least in part on the capability information. In some aspects, the capability information indicates a minimum gap between a message scheduling a page and a message carrying the page, which allows a two-stage wake up to be implemented for UEs that support a PEI and UEs that lack PEI support.
