Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may distinguish between synchronization signal blocks (SSBs) intended for different classes of UEs. For example, a base station may transmit different SSBs in a physical broadcast channel with different configurations or parameters to indicate different UE classes, where UEs may monitor for and receive SSBs for their UE class. A UE may operate according to a UE class (e.g., New Radio (NR) Light) associated with lower bandwidths and may identify SSBs associated with this UE class to connect with a base station. The UE may identify the SSBs associated with the UE class based on a subcarrierlevel offset value either implicitly or explicitly indicated to the UE. Additionally, the base station may transmit fields to indicate different parameters for subsequent communications transmitted according to the UE class.

Abstract: In an aspect, a BS is configured as a serving cell of a UE. The BS transmits data to the UE in accordance with a frequency hopping scheme over a first set of T-F resources of a first BWP and a second set of T-F resources of a second BWP. The BS (or another BS) further transmits, to the UE over a third BWP that is different than the second BWP, a PDCCH including a PI field with a PI associated with the transmitted data over the second set of T-F resources of the second BWP. The UE receives the data and the PDCCH. The UE processes the received data over (at least) the second set of T-F resources based on the PI.

Abstract: Various aspects of the present disclosure generally relate to configurations for new radio (NR) devices with reduced capabilities. In some aspects, a user equipment (UE) may determine a configuration from stored configuration information, where the configuration specifies a subset of features that NR UE with reduced capabilities is to support. The UE may communicate according to the configuration of reduced capabilities, or fall back to a set of further reduced UE capabilities. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to frequency hopping within a virtual BWP. In some aspects, a UE may determine a virtual bandwidth part (BWP) in which to frequency hop from a first narrow BWP to a second narrow BWP by a frequency offset. The virtual BWP may have a same subcarrier spacing as the first narrow BWP and a larger bandwidth than the first narrow BWP. The UE may perform communication based at least in part on frequency hopping within the virtual BWP. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a starting symbol of a radio frequency (RF) retuning gap between a first plurality of repetitions of an uplink transmission in a first frequency hop and a second plurality of repetitions of the uplink transmission in a second frequency hop. The starting symbol of the RF retuning gap is based at least in part on a starting symbol of the second plurality of repetitions and a quantity of symbols included in the RF retuning gap. The UE may determine an ending symbol of the RF retuning gap based at least in part on the starting symbol of the second plurality of repetitions. The UE may perform RF retuning during the RF retuning gap. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a modified physical downlink control channel (PDCCH) configuration for low tier UEs; receive downlink control information (DCI) configured according to the modified PDCCH configuration; and process the DCI according to the modified PDCCH configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to multi-slot transmission time interval based channel state information (CSI) and uplink shared channel (UL-SCH) multiplexing. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message and determine, based at least in part on the DCI message, a schedule for multiplexing UL-SCH data and one or more components of uplink control information (UCI) in a plurality of slots on a physical uplink shared channel (PUSCH). The components may include a CSI report for a plurality of transmission reception points. The UE may multiplex the UL-SCH data and the one or more components into the plurality of slots based at least in part on the schedule. Numerous other aspects are provided.

Abstract: User equipments (UEs) with reduced capabilities may need a relaxed processing timeline relative to standard UEs. The relaxed processing timeline may provide UEs with reduced capabilities an appropriate amount of time (e.g., during a random access procedure) to decode messages from a base station (BS) and/or to prepare uplink messages. Aspects of the disclosure relate to a UE configured to transmit a message to a serving BS, the message including a request for timeline relaxation for transmission of a subsequent message, the message and the subsequent message being associated with a random access procedure. The UE receives a response message associated with the random access procedure and indicating one or more timing offsets corresponding to the timeline relaxation. The UE transmits the subsequent message to the serving BS based on the one or more timing offsets indicated by the serving BS. The subsequent message acknowledges the response message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal configuring a set of random access opportunities over which to transmit a preamble associated with a random access procedure, each random access opportunity associated with a set of one or more uplink data opportunities. The UE may identify a repetition parameter for an uplink message. The UE may select a random access opportunity from the set of configured random access opportunities for transmitting the preamble based at least in part on the repetition parameter. The UE may transmit the preamble on the selected random access opportunity. The UE may transmit one or more repetitions of the uplink message based at least in part on the set of one or more uplink data opportunities associated with the selected random access opportunity.
