Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, signaling that indicates at least a first random access channel (RACH) occasion (RO) partition and a second RO partition. The first RO partition may be associated with different uplink transmission capabilities than the second RO partition. The UE may select an RO in the first RO partition or the second RO partition based at least in part on a metric that relates to an uplink transmission capability of the UE. The UE may transmit, and the network node may receive, a preamble in the selected RO to initiate a RACH procedure. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine an inactivity timer associated with a first set of one or more beams used for communicating with a network entity associated with a satellite has expired. The UE may identify location information corresponding to the location of the UE with respect to the network entity. The UE may identify beam geometry information for one or more beams associated with the network entity. For example, the UE may receive the beam geometry information from the network entity. The UE may process the location information and the beam geometry information to identify a second set of one or more beams, the second set different than the first set. The UE and the network entity may communicate according to the second set of one or more beams.

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: Apparatus, methods, and computer program products for handover are provided. An example method may include receiving a physical downlink shared channel (PDSCH) transmission from a network entity, the PDSCH transmission comprising a set of radio resource control (RRC) messages, each RRC message in the set of RRC messages comprises a respective group handover configuration in a set of group handover configurations associated with a respective UE in a set of UEs including the UE, the set of RRC messages being included in a set of medium access control (MAC) service data units (SDUs) (MAC SDUs) in a MAC protocol data unit (PDU). The example method may further include processing a first subset of the MAC SDUs that are associated with the UE and discard a second subset the MAC SDUs that are not applicable to the UE.

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.
