Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support non-terrestrial network (NTN) signaling between both terrestrial and non-terrestrial devices. A user equipment (UE) supporting such NTN signaling may receive a downlink message indicating a first configuration for a first transmission reception point corresponding to a first cell of the NTN, and a second configuration for a second transmission reception point corresponding to a second cell of the NTN. The UE may then perform one or more synchronization measurements to synchronize uplink communications with the first transmission reception point and the second transmission reception point and in order to perform multi-transmission reception point communications in the NTN. The UE may then transmit one or more uplink messages to the first transmission reception point, to the second transmission reception point, or both, in accordance with the one or more synchronization measurements.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate in a wireless communications system. The UE may receive first control signaling indicating a first radio network temporary identifier (RNTI) and a first feedback process identifier, where the first RNTI indicates scheduling of a unicast downlink transmission. The UE may also receive second control signaling indicating a second RNTI and a second feedback process identifier, where the second RNTI indicates scheduling of a multicast downlink transmission. The UE may manage a hybrid automatic repeat request (HARM) process at the UE associated with the unicast downlink transmission and the multicast downlink transmission based on the first RNTI, the first feedback process identifier, the second RNTI, and the second feedback process identifier. The UE may also simultaneously process multicast downlink transmission and broadcast signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a terrestrial characteristic of a cell associated with the base station. A UE may perform a synchronization procedure with the cell and may receive, as part of the synchronization procedure, broadcast signaling associated with the cell. The broadcast signaling may identify the terrestrial characteristic of the cell. The base station may initiate communications with the UE based on the broadcast signaling including the indication of the terrestrial characteristic of the cell.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for establishing rules for scheduling downlink data transmissions and flow control feedback for the downlink data transmissions to avoid confusion at a base station and a user equipment (UE). In one example, when flow control feedback from a UE is disabled for a downlink data transmission, the UE may still operate according to a timing for reporting flow control feedback for the downlink data transmission. In this example, the UE may drop (e.g., refrain from decoding) other downlink data transmissions based on the timing for reporting flow control feedback. In another example, when flow control feedback from a UE is disabled for a downlink data transmission, other downlink data transmissions to the UE may be scheduled according to one or more rules to avoid confusion.

Abstract: Methods, systems, and devices for wireless communications are described. In some networks, a user equipment (UE) may switch between serving beams of a transmitting device that are associated with different bandwidth parts of a radio frequency spectrum. To improve aspects of beam measurement and selection, a UE may be configured to support various techniques for beam measurement according to the different bandwidth parts. For example, a UE may receive a beam measurement configuration associated with one or more beams, and may monitor for reference signals associated with the beams using the different bandwidth parts. The UE may determine a channel quality of one or more of the beams based on the monitoring, and transmit a beam measurement report to the network in accordance with the beam measurement configuration. In some examples, such a report may be transmitted based on the UE determining that an event condition is satisfied.

Abstract: A user equipment may be configured to implement a procedure for implementing a procedure for updating cell-specific parameters used by a UE in non-terrestrial networks (NTN). In some aspects, the UE may receive, from a network entity, during a modification period of system information, system information including one or more cell-specific parameters. Further, the UE may enter a radio resource configuration (RRC) connected mode based upon receipt of the system information, and transmit an acquisition indication of receipt of the system information, the acquisition indication identifying an instance within the modification period of receipt of the system information.

Abstract: A user equipment (UE) selects or reselects a target cell of a non-terrestrial network or resumes connectivity with the target cell after a satellite handover for a permanently fixed low Earth orbit (LEO) cell. The target cell is a serving or non-serving cell. The UE determines a cell type of the target cell. The cell type may be a LEO cell type, a geostationary Earth orbit (GEO) cell type, a moving cell type, a fixed cell type, a temporarily fixed LEO cell type, or a permanently fixed LEO cell type. The UE completes selection or reselection of the target cell or completes the connectivity with the target cell, based on the cell type.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may enable selection of a modulation order (Qm) parameter, a transport block size (TBS) parameter, a quantity of subframes in a transport block (NSF) parameter, and/or the like. For example, based at least in part on receiving a downlink control information or another factor, a user equipment may select, for example, a table of Qm, TBS, and NSF values and may select a particular set of a Qm value, a TBS value, and an NSF value from the table. In this way, the UE may use a higher order modulation and coding scheme in, for example, a narrowband Internet of Things deployment.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.
