Abstract: The present disclosure provides various modifications to existing techniques for transmitting ACK and/or NACK in an narrow band communications system. For example, in a first aspect, an apparatus receives a downlink transmission and transmits a single tone ACK on an ACK channel using time-spreading. In another aspect, an apparatus determines whether an ACK has been received from a UE within a threshold amount of time, and when an ACK has not been received from the UE for at least the threshold amount of time, transmitting an indication to the UE to transmit regarding the ACK

Abstract: Certain aspects of the present disclosure provide techniques for configuring for communications on noncontiguous carriers of a single cell. By combining multiple noncontiguous carriers into a single cell, broadcast overhead can be reduced and cell management (i.e., only one cell) can be simplified. For example, a network entity may transmit to a user equipment (UE) configuration information that configures the UE for communications on noncontiguous carriers of a single cell. The network entity and the UE may then communicate on the noncontiguous carriers in accordance with the configuration information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may receive, from a second network node, a first indication of an air interface resource configuration that is associated with the second network node. The first network node may transmit a cross link interference (CLI) measurement configuration that is addressed to a user equipment (UE) associated with the first network node, the CLI measurement configuration being associated with a CLI measurement procedure at the UE and being based at least in part on the air interface resource configuration. The first network node may receive a second indication of a CLI measurement report that is associated with the UE, the CLI measurement report including a CLI metric that is based at least in part on the CLI measurement configuration. Numerous other aspects are described.

Abstract: Scheduling information configured to schedule a secondary uplink on a second cell is received on a first cell. Downlink reference signals (DL RSs) are received on the first cell, or radio resource control (RRC) signaling configuring a third cell is received and the DL RSs are received on the third cell. The secondary uplink is transmitted on the second cell. An apparatus receives RRC signaling configuring a location of DL RSs associated with a secondary uplink. The DL RSs are at least one of: within a first carrier bandwidth or a first bandwidth part (BWP) of the secondary uplink, within a second carrier bandwidth or a second BWP of a second cell configured to the apparatus for a non-secondary uplink, or are not within any cell configured to the apparatus. The apparatus transmits the secondary uplink at a power or with timing control determined with the DL RSs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a UE-specific configured grant (CG) small data transmission (SDT) configuration with parameters specific to CG-SDT in a non-terrestrial network (NTN). The UE may receive system information associated with validation of the parameters for CG-SDT on the NTN. The UE may transmit an SDT to a network entity of the NTN using one or more of the parameters. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described that provide for multi-RAT spectrum sharing (MRSS) for network access procedures. MRSS may provide common resources for initial access information for each of two or more RATs. In some aspects, an initial bandwidth part (BWP) configuration may be provided for a MRSS cell, and a user equipment (UE) supporting MRSS, as well as UEs that support only one RAT (e.g., a legacy UE that supports an older technology RAT), may monitor for network access information in the common resources, such as a synchronization signal block (SSB) that provides access information for two RATs.

Abstract: A reference signal measurement method includes: receiving, at a user equipment from a transmission/reception point, a quasi co-location indication that indicates that a first signal, from the transmission/reception point and corresponding to a first radio access technology, is quasi co-located with a second signal from the transmission/reception point and corresponding to a second radio access technology that is different from the first radio access technology; receiving, at the user equipment from the transmission/reception point, the first signal and the second signal; and measuring, at the user equipment, the first signal based on the quasi co-location indication indicating that the first signal is quasi co-located with the second signal.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive a configuration of a set of search space sets for a downlink control channel. The UE may determine a quantity of downlink control channel units (e.g., downlink control channel elements, downlink control channel candidates) for monitoring over the set of search space sets, where downlink control channel units that overlap may be counted separately. For instance, the downlink control channel units may overlap in time and frequency and/or may have a same associated payload size and associated set of control channel elements. The UE may monitor the downlink control channel according to a subset of the set of search space sets, where the subset excludes one or more of the set of search space sets based on the quantity of downlink control channel units satisfying a threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects generally relate to reducing interference in a user equipment (UE) with respect to non-cell defining synchronization signal and physical broadcast channel block (NCD-SSB) communications. Some aspects more specifically relate to configuring the UE to mitigate interference caused by collisions between the NCD-SSB and a cell-defining SSB (CD-SSB). Some aspects more specifically relate to configuring the UE to mitigate interference and/or other issues that might occur when at least a portion of the NCD-SSB is received during one or more downlink slots or symbols and one or more uplink slots or symbols.

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.
