Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure a physical downlink control channel (PDCCH) component of a message B (msgB) communication to include a first portion of the signaling information for physical uplink control channel (PUCCH) for hybrid automatic repeat request (HARQ) feedback associated with the msgB communication and the signaling information for HARQ combining of msgB. The BS may configure a physical downlink shared channel (PDSCH) component of the msgB communication to include a second portion of the signaling information for PUCCH and msgB HARQ combining. The distributed mapping for the signaling information to the PDCCH and PDSCH components of msgB can be indicated by system information, RRC signaling, or hard coded in specifications. The BS may transmit the msgB communication to one or more UEs. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for a configurable mode for a response to random access message. A method that may be performed by a user equipment (UE) includes receiving an indication from a base station (BS) that the BS operates according to a first mode in which the BS unicasts a RACH response during a two-step RACH procedure or a second mode in which the BS multicasts the RACH response. The RACH response includes a PDCCH and PDSCH. The UE sends a RACH message to the BS comprising a preamble and payload. The UE monitors and decodes the PDCCH of the RACH response based on the indicated first mode or second mode. The UE decodes the PDSCH of the RACH response and sends feedback to the BS based on the indicated first mode or second mode.

Abstract: Certain aspects of the present disclosure provide techniques for a hybrid automatic repeat request (HARQ) procedure for the random access channel (RACH) response message in a two-step RACH procedure. A method that may be performed by a user equipment (UE) includes sending a RACH message to a base station (BS) during a two-step RACH procedure. The RACH message includes a RACH preamble and a RACH payload. The UE monitors a RACH response message from the BS during a random access response (RAR) window. The UE transmits a retransmission of the RACH message, an acknowledgement (ACK) to the RACH response message, a negative acknowledgment (NACK) to the RACH response message, or does not transmit, to the BS based on whether a RACH response message carrying a success RAR or a fallback RAR, or no RACH response message, is received from the BS during the window.

Abstract: Aspects described herein relate to receiving a configuration indicating multiple association rules associating random access preambles and payload formats, selecting, as part of a random access procedure, a random access preamble from the random access preambles for transmitting over a random access occasion, determining, based at least in part on at least one of the association rules in the configuration, a payload format associated with the random access preamble and a corresponding payload resource unit, and transmitting the random access preamble over the random access occasion and, according to the payload format, an associated payload over the corresponding payload resource unit. Multiplexing of payload resource units with same or different payload formats can be performed in time, frequency and code domains, based on the received configuration.

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: Embodiments methods implemented with a server or a processor of a mobile communication device (e.g., a multi-standby communication device) reduce the redundancy information needed to achieve adequate reception service on a first radio access technology (RAT) sharing an RF resource with a second RAT. The device processor may implement at least one tune-away management strategy that mitigates the amount of data for the first RAT that is lost during the tune-away event. Thus, by implementing the one or more tune-away management strategies, the device processor may ensure that less redundancy information overhead is needed to correct or replace lost or partially received data, improving latency, channel usage, and the first RAT's overall reception performance. In some embodiments, a server may implement one or more strategies for including redundancy information into data that is sent to a first RAT to mitigate the negative effects of tune aways on the first RAT.

Abstract: Certain aspects of the present disclosure provide techniques for updated system information (SI) delivery. In some cases, a method performed by a user equipment may include receiving, from a network entity, a configuration for a common control resource set (CORESET) on a first downlink bandwidth part (BWP) and a configuration for one or more common search space (CSS) sets within the common CORESET for physical downlink control channel (PDCCH) monitoring. The method may further include receiving, from the network entity on the first downlink BWP, a first set of system information (SI) scheduled by a physical downlink control channel (PDCCH) in the one or more CSS sets, and receiving, from the network entity on a second downlink BWP, updated SI or an indication of updated SI.

Abstract: Methods, apparatuses, and computer-readable storage medium for supporting mobile-originated small data transmission (MO-SDT) and mobile-terminated small data transmission (MT-SDT) or point-to-multi-point (P2M) multicast and broadcast services (MBS) are provided. An example method may include transmitting, to a base station, a capability indication representing support of MO-SDT and MT-SDT. The example method may further include receiving, from the base station, one or more configurations for the MO-SDT and the MT-SDT in a radio resource control (RRC) message, the RRC message comprising at least an RRC release message. The example method may further include transitioning to an RRC inactive state. The example method may further include transmitting, to the base station, a common control channel (CCCH) message in a MO-SDT transmission while in the RRC inactive state.
