Abstract: Methods, systems, and devices for wireless communication are described related to a duty cycle configuration for power saving. A user equipment (UE) may receive control signaling indicating a duty cycle for cycling between a first power state associated with a first configuration and a second power state associated with a second configuration. In some examples, the first and second configurations may indicate a bandwidth part (BWP) configuration, restricted reception or transmission of one or more channels within the BWP configuration, or both for the UE. The UE may communicate first data traffic in accordance with the first configuration while operating in the first power state. The UE may transition from the first power state to the second power state in accordance with the duty cycle. The UE may communicate second data traffic in accordance with the second configuration while operating in the second power state.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating support for multiple configured grant small data transmission (CG-SDT) configurations and may receive one or more downlink messages that collectively indicate a downlink bandwidth part (BWP), an uplink BWP and a set of CG-SDT configurations based on transmitting the capability message. Each CG-SDT configuration may be associated with respective time and frequency resources for use in one or more CG-SDTs. The UE may transition out of a radio resource control (RRC) connected state based on receiving the one or more downlink messages. The UE may transmit an initial CG-SDT that includes a common control channel (CCCH) message using time and frequency resources associated with one or more of the set of CG-SDT configurations based on comparing the respective time and frequency resources associated with the each of the CG-SDT configurations.

Abstract: Certain aspects of the present disclosure provide techniques for compact downlink control information (DCI) signaling design for ultra-reliable low-latency communications (URLLC). A method for wireless communications performed by a base station (BS) is provided. The method generally includes generating DCI, the DCI scheduling at least one transmission, according to a first DCI format. The first DCI format is compressed relative to a second DCI format and includes a carrier indicator field (CIF) and/or a rate-matching indicator field. The BS transmits the DCI to a user equipment (UE). The UE communicates with the BS based on the received DCI.

Abstract: In a legacy gNB (e.g., pre-Rel. 17 gNB), RC UEs with only 1 or 2 receive antennas may have a geographic coverage area for control data and traffic data that is smaller than their geographic coverage area for SSB with respect to certain legacy gNBs. By contrast, at least some new gNBs (e.g., Rel. 17+ gNBs) have the capability to provide uniform geographic coverage for RC UEs with respect to SSB, control data and traffic data. In an aspect of the disclosure, a particular class of UEs (such as RC UEs) is steered towards particular cells (e.g., Rel. 17+ gNBs) via one or more biased class-specific cell selection parameters included in system information from the cells.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration message with a configured grant for a plurality of uplink transmissions. The user equipment may transmit, using a first demodulation reference signal port, a first transmission, of the plurality of uplink transmissions, associated with the configured grant. The user equipment may transmit, using a second demodulation reference signal port that is different from the first demodulation reference signal port, a second transmission, of the plurality of uplink transmissions, associated with the configured grant. Numerous other aspects are provided.

Abstract: Methods, systems, nodes, and devices for wireless communication are described. The method may include a first network node (e.g., a user equipment (UE)) receiving a first message that indicates a first preamble and transmitting a random access request message indicative of a request by the first network node for repetition based transmission of a second message. In response to the random access request, the first network node may receive a random access response message including an indication that the second message is to be transmitted with repetition and transmit the second message in accordance with repetition.

Abstract: Feedback reports (e.g., hybrid automatic repeat request (HARQ)-acknowledgment (ACK) codebooks) may provide feedback for both downlink data messages (e.g., physical downlink shared channel (PDSCH) messages) and control messages (e.g., physical downlink control channel (PDCCH) messages). As such, a base station may transmit an indication of a power savings mode in a control message (e.g., in scheduling downlink control information (DCI)), and the base station may be able to confirm whether a user equipment (UE) received (e.g., and implemented) the power savings mode via the feedback corresponding to the control message carrying the indication of the power savings mode. The techniques described herein may provide for improved synchronization of base station and UE power savings modes (e.g., as a base station may or may not implement a new power saving mode depending on whether the control message indicating the new power saving mode was successfully received and acknowledged).

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: Methods, systems, and devices for wireless communications are described for capability indications by a reduced capability user equipment (UE) and UE-based performance measurement parameter reporting or self-organizing network (SON) parameter reporting based on the capability indications. A reduced capability UE may transmit a set of capabilities to a base station that indicate various types of parameter reporting that are supported at the UE. The base station may identify the UE as a reduced capability device, and set one or more reporting parameters based on the indicated UE capabilities. The base station may provide a reporting configuration to the UE with the one or more reporting parameters, and the UE may provide reporting of measured parameters (e.g., performance measurement parameter reporting or SON parameter reporting) based on the reporting configuration.
