Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for determining whether a user equipment (UE) and a base station of a radio access network (RAN) configured to operate according to compatible variants of a standardized radio access technology (RAT). In some cases, a standard development organization for a geographic territory may modify a standardized RAT in a way that creates a new variant (also referred to as a forked deviation) of the RAT. Depending on what changes are made, the new variant may be compatible or incompatible with the original standardized RAT. This disclosure enables the UE to determine according to which variant of the RAT the RAN is configured to operate and manage connections to the RAN based whether the UE and the RAN are configured to operate according to compatible variants of the RAT.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a multicast message or a broadcast message that uses a radio link control (RLC) format associated with an RLC acknowledged mode (RLC-AM). The UE may decode the multicast message or the broadcast message to identify information associated with an RLC unacknowledged mode (RLC-UM) based at least in part on a capability of the UE. The UE may operate in accordance with the RLC-UM based at least in part on decoding the multicast message or the broadcast message. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a beam used for communicating with a network entity, the beam associated with multiple bandwidth parts (BWPs) including a reference BWP with a first frequency. The UE may receive a BWP configuration from the network entity, the BWP configuration based on changing a frequency for at least one BWP of the multiple BWPs form the first frequency to a second frequency. Additionally or alternatively, the UE may identify a timing threshold associated with a BWP switching operation for multiple BWPs associated with the beam. The UE may switch from the first BWP to a second BWP during the timing threshold. The UE may communicate with the network entity according to the BWP configuration or the second BWP.

Abstract: A wireless communication device can flexibly change subcarrier spacing (SCS) and/or cyclic prefix (CP) in wireless communication. The wireless communication device can transmit, in a first sidelink resource of a sidelink resource pool, a first sidelink transmission using a first configuration of suhcarrier spacing (SCS) and cyclic prefix (CP). The wireless communication device can further transmit, in a second sidelink resource of the sidelink resource pool., a second sidelink transmission using a second configuration of SCS and CP, the second configuration being different from the first configuration in terms of at least one of an SCS or a CP. The techniques allow more efficient switching between SCS and CP configurations withing a resource pool, in the same bandwidth part.
