Abstract: Methods, systems, and devices for wireless communications are described. A base station determines configuration information for a random access procedure, where the configuration information includes a repetition pattern associated with a first message of the random access procedure. A user equipment (UE) receives, from the base station, a configuration message that indicates the configuration information for the random access procedure. The UE determines a repetition pattern associated with a first message of the random access procedure based on the configuration information. The base station receives, from the UE, multiple instances of the first message based on the repetition pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a broadcast message from a base station, the broadcast message including an indication pertaining to system information for reduced-capability UEs including UEs with a bandwidth capability below a threshold, the UE being a reduced-capability UE. The UE may determine, based on the indication in the broadcast message, whether system information for reduced-capability UEs is scheduled to be broadcast by the base station. The UE may then obtain the system information for reduced-capability UEs in accordance with the indication in the broadcast message.

Abstract: An apparatus for wireless communication is provided. The apparatus may be a network node. The apparatus receives a set of uplink transmissions from a set of user equipments (UEs) via a first resource of a non-orthogonal channel, wherein the apparatus is unable to decode the set of uplink transmissions. The apparatus transmits a retransmission request to a subset of the set of UEs. The apparatus receives a retransmission of a first uplink transmission in the set of uplink transmissions via a second resource of the non-orthogonal channel in response to the retransmission request. The apparatus decodes a second uplink transmission in the set of uplink transmissions based on at least the retransmission of the first uplink transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a grant scheduling repetition-based system information block transmissions for the UE, the grant indicating a mapping configuration identifying time-frequency resources for a second repetition of a system information block transmission relative to a first repetition of the system information block transmission. The UE may receive, in a first subset bandwidth of a system bandwidth, the first repetition of the system information block transmission according to the grant. The UE may receive, in a second subset bandwidth of the system bandwidth, the second repetition of the system information block transmission according to the grant and based at least in part on the mapping configuration.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a reduced capability user equipment (UE) may receive signaling indicating a set of repetition levels for receiving control information from a base station and a blind detection threshold for decoding the control information. Upon receiving the signaling, the reduced capability UE may monitor a control channel candidate for the control information based on the set of repetition levels. Once the reduced capability UE detects the control information from the monitoring, the reduced capability UE may perform at least one blind detection on the control channel candidate based on the set of repetition levels and the blind detection threshold and receive the control information from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may send signaling to multiple user equipments (UEs) indicating for the UEs to switch to a radio frequency bandwidth. The UEs may operate according to a reduced set of communication operations in accordance with the radio frequency bandwidth. For example, the UEs may refrain from monitoring one or more channels, may not transmit on one or more channels, or the like. The UEs may switch out of the radio frequency bandwidth based on a trigger event, such as a timer expiring, receiving an indication in a downlink control information (DCI) message, or the like.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a base station, control signaling indicating a proactive traffic reporting configuration identifying a trigger condition for proactively reporting expected data traffic for the UE. The UE may transmit, to the base station based on a satisfaction of the trigger condition, an uplink message including an indication of an expected amount of data traffic for the UE, where the satisfaction of the trigger condition is based on the expected amount of data traffic. The UE may subsequently receive, in response to the uplink message, a downlink message indicating a resource allocated for communicating the expected amount of data traffic, and may communicate at least a portion of the expected amount of data traffic with the base station via the indicated resource.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines a frequency hopping pattern for transmission of a physical random access channel (PRACH) preamble based on an associated PRACH coverage enhancement (CE) level, and transmits the PRACH preamble in accordance with the frequency hopping pattern and the associated PRACH CE level. A base station receives the PRACH preamble, and transmits a response (e.g., Msg2 or MsgA) to the PRACH preamble.

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.
