Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a relationship between preamble sequences of a preamble portion of a random access message and resources for demodulation reference signal (DMRS) sequences and physical uplink shared channel (PUSCH) occasions of a payload portion of a random access message. The base station may map some preamble sequences to some of the DMRS sequences and PUSCH payloads within a mapping period. The base station may transmit, to a user equipment (UE), an indication of the mapping rule between the preamble sequences and the DMRS sequences and payloads. The UE may transmit, based on determining the relationship, at least one preamble sequence in a preamble occasion and at least one DMRS sequence and one payload of the random access message in a PUSCH occasion based on the configured mapping rule.

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: An apparatus, e.g., a UE, for transmission of information modulated onto RSs using index modulation is disclosed. The UE may receive, from a base station, a configuration of one or more RS resources of an RS resource set. The one or more RS resources may be associated with an index modulation technique including a plurality of UL or DL information bits. The UE may transmit, to the base station, or receive, from the base station, the plurality of UL or DL information bits. The plurality of UL or DL information bits may include at least one of one or more first bits or one or more second bits. At least one of the one or more RS resources may be selected based on at least one of the one or more first bits or the one or more second bits.

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 configuration message indicating a configured grant-small data transfer (CG-SDT) group that includes the UE. The CG-SDT group is associated with a downlink beam of the base station and one or more CG-SDT occasions. The UE may transmit, to the base station and within the one or more CG-SDT occasions, an uplink communication, using an uplink beam of the UE corresponding to a downlink beam of the UE, where the downlink beam of the UE is associated with the downlink beam of the base station used for transmitting at least one of the configuration message, a paging message, or a reference signal. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for beam-specific paging in wireless communication systems. An example method generally includes transmitting, to a network entity, an indication of a mobility state of the UE, wherein the indication is transmitted based on a synchronization signal block (SSB) associated with a selected beam direction; and monitoring paging occasions for paging sent using a beam that is quasi-colocated with the selected beam direction associated with the SSB.

Abstract: In an aspect, a user equipment (UE) may receive an uplink (UL) grant (e.g., dynamic UL grant, UL configured grant (CG)) from a network, but may decide to skip the UL grant altogether or not transmit any user plane data on the UL grant. In such instances, the UE may maintain or expedite expiration associated with one or more timers (e.g., discontinuous reception (DRX) and bandwidth part (BWP) inactivity timers, secondary cell (SCell) deactivation timer, etc.). The UE may also maintain or expedite expiration associated with one or more timers if it receives downlink (DL) transmission (e.g., DL semi-persistent scheduling (SPS)) from the network that includes no user plane data.

Abstract: Certain aspects of the present disclosure provide techniques for an on-demand measurement gap for inter-frequency radio resource management (RRM) measurements. A method for wireless communications by a base station (BS) includes configuring a user equipment (UE) in the serving cell for measurement of target cell (s) and with an on-demand measurement gap configuration for measuring the target cell (s). Neighbor cells in a same frequency can coordinate to align synchronization signal block (SSB) or channel state information reference signal (CSI-RS) transmission and provide timing information of the aligned SSB or CSI-RS transmission to a cell in a different frequency. A method by a UE includes receiving an on-demand measurement gap configuration from a serving cell co and measuring target cell (s) based on the measurement gap configuration.

Abstract: Certain aspects of the present disclosure provide techniques for compact downlink control information (DCI) signaling design for ultra-reliable low-latency communications (URLLC). A method for wireless communications performed by a base station (BS) is provided. The method generally includes generating DCI, the DCI scheduling at least one transmission, according to a first DCI format. The first DCI format is compressed relative to a second DCI format and includes a carrier indicator field (CIF) and/or a rate-matching indicator field. The BS transmits the DCI to a user equipment (UE). The UE communicates with the BS based on the received DCI.

Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.
