Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reduced bandwidth devices and particularly, allocation of more than three orthogonal frequency division multiplexing (OFDM) symbols in the time domain to a control resource set (CORESET). In a first aspect, a method for wireless communication includes receiving, from a base station at a user equipment (UE), a first message that indicates a CORESET configuration. The CORESET configuration allocates more than three OFDM symbols in the time domain to a CORESET. The method further includes monitoring a set of time and frequency resources to receive a second message from the base station at the UE. The set of time and frequency resources have the CORESET configuration. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), that is configured for demodulation reference signal (DMRS) bundling, may receive a control message that schedules first and second sets of repetitions of an uplink transmission. The UE may determine a phase coherency configuration to be applied for DMRS transmissions corresponding to each set of repetitions. The phase coherency configuration may be determined based on a phase coherency capability of the UE, and the phase coherency configuration may specify that phase coherency is to be maintained for one or more of the first set of repetitions separate from one or more of the second set of repetitions. The UE may transmit the first set of repetitions with a first set of demodulation reference signals and the second set of repetitions with a second set of demodulation reference signals in accordance with the phase coherency configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform beam sweeping for a physical uplink channel within time domain windows or across time domain windows based on a time domain window index. In cases where frequency hopping is enabled, the UE may transmit uplink repetitions and demodulation reference signals (DMRSs) across two frequency hops during two consecutive time domain windows using a first transmit beam, and may then follow up with transmissions across two frequency hops during the next two consecutive time domain windows using a second transmit beam. Or, the UE may transmit uplink repetitions and DMRSs in a first frequency hop with first and second transmit beams during two respective consecutive time domain windows, and may transmit in a second frequency hop with the first and second transmit beams during the next two respective consecutive time domain windows.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a control message including a first parameter and a second parameter. The first parameter may identify a first uplink control channel resource set for a first type of UE. The second parameter may identify a second uplink control channel resource set for a second type of UE. In some cases, a UE may receive the control message before receiving configuration information identifying a uplink control channel resource configuration. In some cases, a UE may optionally select an uplink control channel resource set based at least in part on the control message and a type of the UE. Also, a UE may transmit on an uplink using a communication configuration associated with the selected uplink control channel resource set. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for managing scheduling of wireless communications. A method that may be performed by a user equipment (UE) includes receiving, from a base station, one or more configurations indicating a plurality of minimum scheduling offset values; receiving, from the base station, a signal indicating one of the minimum scheduling offset values as an updated value to be used for communications with the base station and a type of scheduling; determining a delay based on the type of scheduling; and after the reception of the signal, using the updated value for communications with the base station based on the determined delay.

Abstract: A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

Abstract: A configuration to allow a UE to receive a BWP configuration that supports RC NR. The UE sends information to a network indicating a UE capability of the UE. The UE receives, based on the UE capability, information indicating a BWP associated with a first BWP, the second BWP having a frequency range equal to or less than the first BWP. The UE receives at least one of control information or data based on the indicated first BWP and the second BWP.

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. In some systems, a user equipment (UE) may perform a dual active link handover procedure from a source base station to a target base station. During the dual active link handover procedure, the UE may have connections to both of the base stations concurrently. In such cases, transmission opportunities for communicating with the base stations may conflict. To handle conflicting transmission opportunities, the UE may drop a monitoring occasion or a packet reception for a base station based on prioritization rules. In some cases, to mitigate packet losses, the base station may configure re-transmissions or slot aggregation to provide the UE with additional opportunities to receive a packet. Additionally or alternatively, the UE may transmit a notification message to a base station indicating dropped monitoring occasions or packets.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of resources for transmitting a set of uplink shared channel transmissions and a set of demodulation reference signals (DMRSs) having phase coherence across a set of transmission time intervals (TTIs). The UE may receive, from the base station, a control message indicating a cancellation of a first resource of the set of resources. The UE may determine one or more phase-continuity conditions for the set of resources based on receiving the control message indicating the cancellation of the first resource. The UE may transmit, in remaining resources of the set of resources, at least a subset of the set of uplink shared channel transmissions and at least a subset of the set of DMRSs in accordance with the one or more phase-continuity conditions.
