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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a phase tracking reference signal (PTRS) configuration for a random access channel (RACH) procedure, wherein the PTRS configuration indicates a PTRS density per modulation and coding scheme (MCS). The UE may perform the RACH procedure according to the PTRS configuration and an MCS used for the RACH procedure. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may communicate with multiple beacon devices (e.g., road side beacons), where messages from the road side beacons may be transmitted over a sidelink communications link and may be used to determine a speed and/or location of the wireless device. In some examples, the messages may carry public safety information, location information, navigation information, or other types of information, which may be used, for example, to notify the wireless device of a nearby event, to enable navigation, or the like. When receiving messages from the road side beacons, the wireless device may report a status to a base station, which may determine a relationship between transmissions from the wireless device and predict future transmissions based on the relationship. As a result, the base station may modify communications parameters in accordance with the status of the wireless device.

Abstract: Some techniques and apparatuses described herein provide an indication of a result of decoding a two-step random access channel (RACH) message and an action to be performed by a user equipment (UE). For example, some techniques and apparatuses described herein may provide the indication using a UE contention resolution identity-based approach, wherein the contention resolution identity of the UE may be provided in a random access response. Some techniques and apparatuses described herein may use a fallback indicator that indicates the result of decoding and/or the action to be performed. Some techniques and apparatuses described herein may use a random access response (RAR) subheader that selectively omits a random access preamble identifier based at least in part on the result of decoding and/or the action to be performed.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit uplink data to a base station in a configured grant small data transfer (CG-SDT) occasion in a CG-SDT occasion group associated with multiple UEs. The UE may receive a group common physical downlink control channel (GC-PDCCH) multiplexing CG-SDT feedback targeted to the multiple UEs associated with the CG-SDT occasion group. In some aspects, the CG-SDT feedback multiplexed in the GC-PDCCH includes CG-SDT feedback for the uplink data transmitted in the CG-SDT occasion. Numerous other aspects are provided.

Abstract: Aspects relate to dynamically changing the slot format of a slot between half-duplex and sub-band full-duplex and/or to changing flexible symbols within a flexible slot between half-duplex and sub-band full-duplex when a base station is configured to operate in a sub-band full-duplex mode. A slot format indicator (SFI) indicating the slot format of the slot may be signaled, for example, via downlink control information (DCI) mapped to a downlink control channel or medium access control (MAC) control element (MAC-CE) mapped to a downlink data channel. To improve reliability, various SFI boosting mechanisms may further be employed. For example, the base station may apply a higher aggregation level to the SFI, transmit repetitions of the SFI across multiple beams, apply a CRC enhancement and/or MCS enhancement to the downlink control channel carrying the SFI, and/or apply a power boost to the SFI.

Abstract: Wireless devices are configured to facilitate UE assisted bandwidth part (BWP) selection in wireless communication systems. According to one example, a scheduled entity can receive an RRC reconfiguration message indicating a handover from a source cell to a target cell, identify uplink data in the buffer, and send an enhanced UE assistance information (UAI) transmission to the target cell, the enhanced UAI indicating a preferred BWP of the target cell. In addition, a scheduling entity can receive an enhanced UAI transmission from a scheduled entity indicating a preferred BWP for the scheduled entity, and select the preferred BWP for communication with the scheduled entity from the enhanced UAI. Other aspects, examples, and features are also included.
