Abstract: A user equipment may be configured to perform UE indication to temporarily suspend report occasions. In some aspects, the user equipment may receive, from a base station, out-of-cell reporting configuration including an out-of-cell reporting parameter for reporting layer one (L1) channel information for an out-of-cell beam. Further, the user equipment may send, to the base station for beam selection in consideration of simultaneous access to another base station based on the out-of-cell reporting parameter, the L1 channel information for the out-of-cell beam.

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 broadcast message associated with initial access. The UE may monitor, for an additional message from the base station, a set of monitoring occasions that are non-consecutive across slots, based at least in part on the broadcast message. In some aspects, the set of monitoring occasions are non-consecutive across slots based at least in part on a stored rule that uses a subcarrier spacing. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer program products for SCS RO alignment are provided. An example method includes transmitting, to a base station, a physical random access channel (PRACH) preamble in one RACH occasion (RO) in a first set of ROs in one or more PRACH slots associated with a first subcarrier spacing (SCS), the one or more PRACH slots being within a duration defined based on a PRACH slots time duration for a second subcarrier spacing (SCS). The example method further includes receiving, from the base station, a PRACH response.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, one or more synchronization signal block (SSB) transmissions associated with a first subcarrier spacing (SCS). The UE may receive, from the network entity, one or more initial access transmissions associated with a second SCS, wherein a time location of an initial access transmission, of the one or more initial access transmissions, that uses a beam is based at least in part on a time location of an SSB transmission, of the one or more SSB transmissions, that uses the beam. Numerous other aspects are described.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving a physical broadcast channel (PBCH). The method also includes receiving a number of control resource sets (CORESETS) based on the received PBCH. The method further includes receiving one or more physical downlink control channels (PDSCHs) based on receiving the number of CORESETS.

Abstract: Certain aspects of the present disclosure provide techniques for demodulation reference signal (DMRS) sequence selection. One aspect provides a method for wireless communication by a first wireless node. The method generally includes selecting a type of DMRS sequence to be used for communication with a second wireless node based on a signal quality associated with the communication, receiving a message having the type of DMRS sequence, and performing channel estimation based on the DMRS sequence using the message.

Abstract: Aspects of the present disclosure relate to techniques for physical uplink control channel configuration and coverage enhancement in a wireless communication network. A base station can dynamically indicate a repetition factor for an uplink control channel to improve coverage of the uplink control channel. The base station can explicitly or implicitly indicate the repetition factor using various signaling techniques. The interpretation of an indication of a repetition factor can depend on one or more parameters, for example, a physical uplink control channel (PUCCH) format, an uplink control information size, a code rate, and/or a PUCCH resource set used for the PUCCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of measurements based at least in part on a demodulation reference signal (DMRS) transmitted via a set of beams. The UE may transmit a measurement report indicating the set of measurements based at least in part on the DMRS. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that support techniques for handover in non-terrestrial networks. The described techniques provide for handovers such that a user equipment (UE) may be provided information prior to handover to facilitate rapid handover and rapid recover if handover fails. The information is based on predicted handovers due to motion of non-terestrial network devices (e.g, satellites).
