Abstract: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described that provide for transmitting two or more transport blocks in an uplink transmission, in which a transmitting device may skip transmissions in some portion of a set of allocated resources for the transport blocks. Uplink data may be encoded to be transmitted via the multiple transport blocks, where a first transport block may have first transport block size that is different than a second transport block size of a second transport block. The transport block sizes may be less than the size of the set of allocated resources, and the transport blocks may be transmitted via the different transmission layers, and a portion of the allocated resources may be unused. The transmitting device may provide an indication of the unused resources for use in decoding the transport blocks.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a control message indicating one or more parameters for measuring multiple reference signals. The one or more parameters may be associated with adjusting one or more measurement periodicities. The UE may measure respective channel quality metrics for the multiple reference signals, where the multiple reference signals includes a first set of reference signals associated with a first transmission reception point. The UE may adjust a measurement periodicity for the first set of reference signals according to a first parameter of the one or more parameters based on a first channel quality metric associated with the first set of reference signals, where the measurement periodicity for the first set of reference signals is separately adjustable relative to a measurement periodicity for the second set of reference.

Abstract: Wireless communications systems may support flexible waveform configuration for autonomous uplink transmissions. A base station may transmit broadcast signaling (e.g., a system information block (SIB)) indicating waveform configuration information for an autonomous uplink transmission by a user equipment (UE). In some cases, the broadcast signaling may include a waveform configuration field (WCF) that may indicate whether flexible waveforms for autonomous uplink are supported, may configure a waveform type, may indicate waveform configuration mapping rules, etc. As such, a UE may identify whether flexible waveform configuration for autonomous uplink is supported, and may determine waveform types for autonomous uplink transmissions based on waveform type configuration information from a base station (e.g., which may include an indication of whether flexible waveform configuration is supported, an indication of waveform type/scenario mapping rules, etc.), one or more LUTs, identified autonomous uplink scenarios, autonomous uplink transmission parameters, or some combination thereof.

Abstract: Certain aspects of the present disclosure provide techniques for a floating synchronization signal block measurement timing configuration (SMTC) for SSB-based radio resource management (RRM) in asynchronous networks, such as new radio (NR). A base station (BS) determines a floating SMTC for measurement of a target cell and provides the floating SMTC to at least one user equipment (UE) in the serving cell, wherein the target cell and the serving cell are asynchronous. The BS determines a measurement gap that covers the floating SMTC. The UE monitors in the measurement gap for a SSB transmission of the target cell based on the floating SMTC.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may obtain an indication of a packet data unit (PDU) set dependency pattern for at least a first PDU set and a second PDU set of a group of PDU sets, where each PDU set of the group of PDU sets is associated with a same traffic flow. The PDU set dependency pattern may indicate a relationship between the first PDU set and the second PDU set for decoding the first PDU set and the second PDU set. The wireless device may obtain the indication of the PDU set dependency pattern as part of metadata associated with the first PDU set or via a control plane message. The wireless device may obtain the group of PDU sets and may decode at least the first PDU set and the second PDU set according to the PDU set dependency pattern.

Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, first component carrier may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and second component carrier may be an assisting carrier such as a sub-6 GHz carrier or a different MMW carrier. In a first example, a UE may trigger beam recovery for first component carrier (on second component carrier), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on second component carrier. In a second example, a new scheduling request (SR) may be defined on first component carrier for second component carrier beam recovery. In a third example, RACH resources or procedures on second component carrier may be used to perform the beam recovery for first component carrier.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a grant scheduling repetition-based system information block transmissions for the UE, the grant indicating a mapping configuration identifying time-frequency resources for a second repetition of a system information block transmission relative to a first repetition of the system information block transmission. The UE may receive, in a first subset bandwidth of a system bandwidth, the first repetition of the system information block transmission according to the grant. The UE may receive, in a second subset bandwidth of the system bandwidth, the second repetition of the system information block transmission according to the grant and based at least in part on the mapping configuration.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein relate to a network entity indicating a configuration for a user equipment (UE) for wake up radio signaling when the main radio of the UE is in a sleep mode. The UE may monitor for and receive, using the wake up radio, a wake up signal, a low power reference signal, or a low power synchronization signal from a second UE in accordance with the configuration. If the UE receives a wake up signal from the second UE, the UE may establish communications with the second UE or with the network entity based on the wake up signal.
