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 control node may receive, from a wireless node, a status report of an unlicensed band associated with an unlicensed channel access of the wireless node, wherein the status report indicates listen-before-talk (LBT) failures during the unlicensed channel access of the wireless node. The control node may transmit, to the wireless node, an updated configuration for unlicensed channel access based at least in part on the status report of the unlicensed band. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for uplink switching for enhanced mobility. In some aspects, this disclosure provides techniques for potentially reducing or eliminating service interruptions experienced during a handover from a source cell to a target cell. Additionally, this disclosure provides techniques for potentially simplifying or improving uplink communications while a UE is connected to both the source cell and the target cell during the handover. This disclosure further provides techniques for potentially reducing UE power consumption or improving uplink resource utilization during a handover from a source cell to a target cell while a UE is connected to both the source cell and the target cell during the handover.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive, from a second wireless communication device, an announcement associated with a first future communication and that indicates a set of resources associated with the first future communication. The first wireless communication device may communicate using the set of resources based at least in part on a determination that an estimated interference that will result from a second future communication using the set of resources satisfies an interference condition. Numerous other aspects are described.

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: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

Abstract: Certain aspects of the present disclosure provide techniques performing measurement reporting. One aspect is a method for performing measurement reporting at a user equipment, including: receiving, from a master node, a message comprising a measurement configuration for a secondary node; entering an inactive state; performing measurements according to the measurement configuration for the secondary node immediately after entering the inactive state; generating a measurement report based on the measurements; transmitting, to the master node, an RRC resume request message; receiving, from the master node, an RRC resume message comprising a request for measurement reporting; and transmitting, to the master node, an RRC resume complete message comprising the measurement report; and receiving data from the secondary node.
