Abstract: Methods, systems, and devices for wireless communications are described. A base station may communicate with a user equipment (UE) or multiple UEs using multicast transmissions, and each of the multiple UEs may use shared resources to transmit feedback. A UE may receive a power control configuration associated with multicast communications and indicating one or more control parameters or weighting factors for uplink feedback. The UE may monitor a set of downlink resources for the multicast message from the base station, and may determine a decoding failure for the multicast message. The UE may determine whether to transmit uplink feedback to the base station based on the received power control parameters, such as adjusting UE transmit power using a weighting factor or other power control parameters. The UE may determine whether to transmit the uplink feedback message indicating the decoding failure based on the power control configuration.

Abstract: Methods, systems, and devices for wireless communications are described that support techniques for wireless communications using preconfigured uplink resources. Generally, the described techniques provide for enhancement of communication features including frequency hopping, an uplink control channel, coverage enhancement, timing advance, uplink power control, reconfiguration, a downlink control channel, a downlink data channel, retransmissions, or subcarrier spacing for a UE in idle mode. The UE may receive an uplink resource configuration for uplink communications in idle mode, the uplink resource configuration comprising an indicator associated with allocated resources for the uplink communications in idle mode and a set of parameters. The UE may transmit, while in idle mode, a first uplink transmission associated with a transport block on the allocated resources and according to one or more of the parameters, and monitor for a response to the first uplink transmission.

Abstract: Methods, systems, and devices for wireless communications are described to improve support for broadcast systems. In some wireless communications systems, such as broadcast systems for a multimedia broadcast/multicast service (MBMS), an inter-site distance between transmitters or between a transmitter and a receiver may be relatively large compared to an inter-site distance for other scenarios of a wireless communication system (for example, cellular data or talk scenarios). A transmitter in a broadcast system may adjust one or more characteristics of resources in a frame, such as the subframe structure, slot structure, or symbol structure, in carriers dedicated for MBMS resource transmissions. For instance, the transmitter may adjust durations of one or more symbols in a frame.

Abstract: Methods, systems, and devices for wireless communications are described that provide for multiple-input multiple-output (MIMO) transmissions of control information using downlink control channel resources, such as physical downlink control channel (PDCCH) resources. The MIMO transmissions may provide control channel transmissions to multiple UEs using the same time-frequency resources. A base station may use a subset of control channel monitoring entities for MIMO control channel transmissions, and another subset of control channel monitoring candidates for non-MIMO control channel transmissions. Control channel monitoring entities for MIMO transmissions may be defined separately from non-MIMO or legacy control channel candidates.

Abstract: Apparatus, methods, and computer-readable media for facilitating on-demand ephemeris and beam information requests are disclosed herein. An example method for wireless communication at a UE includes transmitting a request for requested information, the requested information including one or more of system information and satellite information. The example method also includes receiving a response message based on the request, the response message including one or more of: an NTN system information block, satellite information associated with at least one requested communication satellite, and beam information associated with the at least one requested communication satellite.

Abstract: Methods, systems, and devices for wireless communications are described. that support preconfigured uplink resources (PUR) in wireless communications. A base station may communicate that support for PUR is available, and may allocate PUR resources to a user equipment (UE) based on requests from the UE. The UE may receive an indication that the base station supports PUR, such as via a system information block (SIB), determine to request PUR, and transmit a PUR request message to the base station. A PUR response from the base station may indicate a PUR allocation for the UE that may be used for uplink transmissions. Uplink transmissions that use PUR may be acknowledged by the base station based on a QOS associated with the uplink transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message from a base station that schedules multiple transport blocks (TBs) to be transmitted to the UE. Accordingly, the UE may determine a bundling configuration for grouping the multiple TBs into separate groups of TBs such that separate acknowledgment (ACK) feedback messages are transmitted by the UE for each group of TBs to indicate whether each of the TBs in each TB group was correctly received and decoded. In some cases, the UE may determine the bundling configuration based on radio resource control signaling from the base station, DCI signaling from the base station, relationships or equations or tables defined for the UE, or a combination thereof. Additionally, the UE may determine resource locations and timelines for transmitting the separate ACK feedback messages.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for random access channel communications in non-terrestrial networks. A method that may be performed by a user equipment (UE) includes transmitting a physical random access channel (PRACH) preamble to the network entity in a random access (RA) occasion; and monitoring for a random access response (RAR) within a RAR window with a start position determined based at least in part on the RA occasion, round trip time parameters for non-terrestrial network communications, and one or more timing offset parameters.

Abstract: A method by a user equipment (UE) includes receiving at least one time offset for scheduling non-terrestrial communications. The at least one first time offset is configured according to a numerology and/or a bandwidth part (BWP). The UE communicates in accordance with the time offset(s). The time offset may be a single time offset that applies across all numerologies or may be multiple time offsets, each specific to a particular numerology or bandwidth part (BWP). The time offset may be a single time offset scaled based on a current numerology configured for communications. The time offset may apply across different bandwidth parts (BWPs) or across multiple component carriers from which the UE is receiving downlink data.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving a first message comprising a configuration for reconstructing a bandwidth part (BWP) for a network entity. The BWP may be used on a non-terrestrial beam of a non-terrestrial entity. The method also includes reconstructing a BWP of the BWPs based on the configuration. The method further includes switching from a current BWP to the reconstructed BWP to communicate with the network entity, e.g., non-terrestrial entity.
