Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for receiving, from a network entity, a configured grant associated with a listen-before-talk (LBT) procedure; determining a transmission priority on the configured grant associated with the LBT procedure; and determining a logical channel based on the transmission priority on the configured grant, wherein determining the logical channel further comprises determining that a scheduled transmission includes one or more signaling data transmissions on the configured grant, the one or more signaling data transmissions corresponding to at least one of a signaling radio bearer 0 (SRB0), SRB1, and SRB3; adjusting a priority level for the one or more signaling data transmissions to a highest priority level corresponding to a higher channel access priority class; and transmitting, to the network entity, on the configured logical channel of the configured grant after successfully performing the LBT procedure.

Abstract: The present disclosure relates to wireless communications, and more particularly to enhancements to a random access channel (RACH) procedure for use in New Radio (e.g., 5G) communications in the unlicensed spectrum (also referred to as NR-U). The present disclosure provides a user equipment (UE) or network entity that determines an available RACH occasion (RO) within a slot for a message transmission according to one of a two-step RACH procedure or a four-step RACH procedure, wherein the available RO is adjacent to at least one unavailable RO within the slot. The UE or network entity may further perform, during the RO, the message transmission according to one of the two-step RACH procedure or the four-step RACH procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may attempt to receive one or more random access channel (RACH) messages from one or more user equipment (UEs); and transmit, based at least in part on the determination of a completion of processing of any received RACH messages of the one or more RACH messages, an early termination message to a UE to terminate a random access response window. In some aspects, a UE may transmit another RACH message as a response to receiving the early termination message. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to procedures for supporting conditional new radio (NR) secondary node (SN) addition and change by reusing conditional handover (CHO) procedures. In some aspects, the procedures include a method for wireless communications by a master node (MN), comprising identifying a set of candidate cells for a conditional addition or change as an SN for a UE based on execution criteria, and signaling configuration information regarding the set of candidate cells to the UE.

Abstract: Certain aspects of the present disclosure are directed to a method for wireless communication. The method generally includes receiving a message for dual-active-protocol stack (DAPs) handover (HO) from a source network entity to a target network entity, wherein carrier-aggregation (CA) is configured with the source network entity prior to reception of the message for HO, deactivating the CA in response to reception of the message for handover (HO) to activate a single carrier mode with the source network entity, and performing the HO from the source network entity to the target network entity during a HO period, wherein the single carrier mode is maintained with the source network entity during at least a portion of the HO period, and wherein connection with the target network entity is maintained during the at least the portion of the HO period.

Abstract: Methods and apparatus for switching bearers between radio access technologies (RATs) are described. According to aspects of the present disclosure, the uplink part of a bearer may be served by one RAT, while the downlink part of the bearer is served by another RAT. A part of a bearer may be served by more than one RAT. Methods and apparatus for communicating via bearer with parts served by differing RATs are also described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a radio resource control (RRC) resume message, associated with transitioning the UE from an inactive state to a connected state. The UE may configure, based at least in part on receiving the RRC resume message, the UE with a serving cell common configuration, associated with a serving cell of the UE, received in a system information block (SIB) associated with the serving cell. Numerous other aspects are provided.

Abstract: An apparatus receives a small data transmission during an RRC inactive mode, without transitioning the UE to an RRC connected mode. The UE receives a page from a base station for a downlink data transmission while in the RRC inactive mode. The page may indicate a downlink data transmission to occur without transitioning the UE to an RRC connected mode and may indicate a RACH preamble to the UE. The UE transmits a random access preamble to the base station in response to the page and receives a downlink data packet from the base station while remaining in the RRC inactive mode.

Abstract: Certain aspects of the present disclosure relate to methods and apparatuses for signaling mode changes to a plurality of wireless devices. For example, certain aspects provide a method including determining, by a base station, a group of wireless devices of a plurality of wireless devices served by the base station to transition to a first mode of operation, wherein at least one of: the first mode of operation is an inactive mode or at least one of the group of wireless devices is in the inactive mode. The method further includes generating a message comprising information indicative of an identifier associated with the group of wireless devices and information indicative of the first mode of operation. The method further includes multicasting the message to the group of wireless devices.
