Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a random access channel (RACH) procedure with a base station. The UE may receive a message configuring a RACH preamble occasion and an uplink data occasion. The message may be a radio resource control (RRC) message or a system information (SI) message. In some cases, the UE may determine if the RACH preamble occasion, the uplink data occasion, or both are restricted for cancellation based on the message. The UE may determine when to monitor a downlink control channel for dynamic scheduling based on determining which occasions are restricted for cancellation and may transmit a RACH message based on monitoring—or not monitoring—the downlink control channel for dynamic scheduling preempting a RACH occasion. In some other cases, a base station may schedule transmissions to not overlap with configured RACH occasions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive first system information from a base station, the first system information being for reduced-capability UEs including UEs with a bandwidth capability below a threshold, the UE being a reduced-capability UE. The UE may evaluate the first system information for a dedicated field that includes an indicator that additional system information for reduced-capability UEs is to be received in response to on-demand requests. Subsequently, the UE may obtain the additional system information for reduced-capability UEs in accordance with information included in either the dedicated field when the dedicated field is included in the first system information or in a configuration information element of the first system information when the dedicated field is absent from the first system information.

Abstract: Wireless communication systems and methods related to enhancing initial access for multi-beam operations. A user equipment (UE) selects a synchronization signal block (SSB) that corresponds to a beam and has a reference signal received power (RSRP) above a threshold. The UE receives a system information block (SIB) that includes a plurality of SSB and beam-specific system information pairs. The UE selects beam-specific system information by matching the selected SSB to one of SSBs in the multiple SSB and beam-specific system information pairs. The UE establishes a connection with a base station (BS) using the beam-specific system information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be receive a grant configuration including multiple set of parameters, and the UE may select a set of parameters from the configured grant based on a channel condition. In some examples, the UE may be configured to signal to a network (e.g., a base station) the selected set of parameters and their corresponding parameter values. For example, the UE may be configured to signal the selected set of parameters over semi-static signaling (e.g., radio resource control (RRC) messaging) or dynamic signaling (e.g., medium access control-control element (MAC-CE) messaging, uplink control information (UCI) messaging, or the like). By configuring the UE with multiple set of parameters, the UE may adapt to changing channel conditions, which may provide higher reliability and lower latency for wireless communications, as well as reduce power consumption for the UE.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for dynamic switching between non-codebook based and codebook based uplink transmission schemes. An exemplary method that may be performed by a user equipment (UE) generally includes obtaining, from a base station (BS), parameters and a grant of transmission resources for asynchronous non-orthogonal multiple access (A-NOMA) transmissions; obtaining data for transmission to the BS; and transmitting the data in an A-NOMA transmission via the transmission resources according to the parameters while the UE is in a radio resource control (RRC) Inactive mode.

Abstract: Aspects of the present disclosure relate to prioritized random access procedures in wireless systems. An exemplary method generally includes receiving, from a user equipment, a random access request including information identifying a type of a random access event being invoked, identifying one or more parameters associated with a backoff interval to be observed at the user equipment based, at least in part, on a priority associated with the type of the random access event, and transmitting, to the user equipment, a random access response including the identified one or more parameters.

Abstract: Methods, systems, and devices for wireless communications are described. As described herein, a service type may be configured, activated, and utilized for subsequent communications according to the service type. For example, a user equipment (UE) may monitor a downlink control channel associated with the service type based on configuring the service type and activating the service type, receive downlink messages associated with the service type, or transmit uplink messages associated with the service type. In some cases, the service type may be activated by transmitting a medium access control (MAC) control element (CE) or a downlink control information (DCI) message. When traffic associated with the service type is no longer present, the service type may be deactivated based on a deactivation indication and/or a deactivation timer. In some cases, the service type may include an ultra-reliable low latency communication (URLLC) service or a low latency service.

Abstract: Methods, systems, and devices for wireless communications are described that provide for service indication via downlink control information (DCI) in which different services have a same DCI size. Techniques provide also that a DCI format may be indicated by a masking operation on a cyclic redundancy check (CRC) of the DCI. The DCI may include an indicator field that may indicate the service of the associated operation. The indication may also be provided via different monitoring occasions of the DCI transmissions that are associated with different services. Different DCI search spaces also may be associated with different services and provide the service indication. Additionally or alternatively, different scrambling sequences used on all or a portion of control information or demodulation reference signal transmissions may be associated with different services.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station for wireless communication, associated with a first radio access technology (RAT), may generate a message to cause a user equipment to wake up from a power saving state or to reconfigure a cycle associated with the power saving state, wherein the message includes an indication that the user equipment is to wake up from the power saving state or to reconfigure the cycle; and/or transmit the message toward the user equipment via a second base station, associated with a second RAT and the user equipment, to cause the user equipment to wake up from the power saving state or reconfigure the cycle. Numerous other aspects are provided.
