Abstract: Aspects of the present disclosure provide techniques for design of channel raster for narrowband operation. One example method, performed by a base station, generally includes determining, based on one or more conditions, an exact frequency location of one channel of one or more channels to perform narrowband communications with a user equipment. The method also includes transmitting an indication of the one or more conditions to the user equipment. The method further includes communicating with the UE, based at least in part on the exact frequency location of the one channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor, within an activation period for a control channel associated with the UE, for messages from a base station within first monitoring occasions defined by a first monitoring pattern. The UE may further monitor, after expiry of a timer associated with the first monitoring pattern, for messages from the base station within second monitoring occasions defined by a second monitoring pattern. In some aspects, the UE may receive, while monitoring within the first monitoring occasions, control information from the base station, and reset the timer associated with the first monitoring pattern. Additionally, or alternatively, the UE may monitor, after expiry of a timer associated with the second monitoring pattern, for messages from the base station within third monitoring occasions defined by a third monitoring pattern. 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 transmit uplink data to a base station in a configured grant small data transfer (CG-SDT) occasion in a CG-SDT occasion group associated with multiple UEs. The UE may receive a group common physical downlink control channel (GC-PDCCH) multiplexing CG-SDT feedback targeted to the multiple UEs associated with the CG-SDT occasion group. In some aspects, the CG-SDT feedback multiplexed in the GC-PDCCH includes CG-SDT feedback for the uplink data transmitted in the CG-SDT occasion. Numerous other aspects are provided.

Abstract: Some techniques and apparatuses described herein provide an indication of a result of decoding a two-step random access channel (RACH) message and an action to be performed by a user equipment (UE). For example, some techniques and apparatuses described herein may provide the indication using a UE contention resolution identity-based approach, wherein the contention resolution identity of the UE may be provided in a random access response. Some techniques and apparatuses described herein may use a fallback indicator that indicates the result of decoding and/or the action to be performed. Some techniques and apparatuses described herein may use a random access response (RAR) subheader that selectively omits a random access preamble identifier based at least in part on the result of decoding and/or the action to be performed.

Abstract: Idle discontinuous reception (I-DRX) cycles at a user equipment (UE) may be extended via leveraging of paging assistance from a second UE. For example, a low complexity UE may have a connection to a network (e.g., via a link to a base station) as well as a connection to another UE (e.g., via a device-to-device link to a regular UE). In cases where such a low complexity UE receives paging messages from the network, a UE associated with a device-to-device link of the low complexity UE may monitor paging messages on behalf of the low complexity UE. As such, the low complexity UE may extend its I-DRX cycle, as the assisting UE monitors paging information for the low complexity UE. The assisting UE may forward paging information for the low complexity UE according to paging occasions of the extended I-DRX cycle of the low complexity UE.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE), generally including receiving, from a network entity, a configuration for a first downlink (DL) bandwidth part (BWP), a first control resource set (CORESET) configured on the first DL BWP, and one or more first search space (SS) sets within the first CORESET, receiving, from the network entity, a configuration for a second downlink BWP, a second CORESET configured on the second DL BWP, and one or more second SS sets within the second CORESET configured on a second DL BWP, and performing one or more idle mode or inactive mode procedures on the first DL BWP or the second DL BWP, based on signaling received while the UE is in an idle state or an inactive state.

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 transmit UE assistance information including UE capability report and measurement report to a base station, and the base station may determine a physical downlink control channel (PDCCH) monitoring configuration for reduced-capability UEs based at least in part on the UE assistance information. The UE may determine whether a group common PDCCH (GC-PDCCH) communication indicates that the zone identifier is activated for an associated monitoring period. The UE may selectively perform one or more PDCCH blind decodes in one or more search space sets associated with the zone identifier during the monitoring period based at least in part on determining whether the GC-PDCCH communication indicates that the zone identifier is activated for the monitoring period. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive at least one control message from a base station, the at least one message jointly scheduling the UE for access network communications between the UE and the base station and for sidelink communications between the UE and another UE, such as another UE in a group of UEs. The UE may determine network control information based on the at least one control message. The UE may also determine sidelink control information based on the at least one control message. The UE may communicate with the base station and the other UE in accordance with the network control information and the sidelink control information, respectively.
