Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may identify information for transmitting to a base station of a non-terrestrial network. The UE may identify that one or more resources allocated for transmitting the information are available based at least in part on identifying the information. The one or more resources include one or more types of uplink resources including physical random access channel (PRACH) resources or physical uplink shared channel (PUSCH) resources for the random access procedure, a PUSCH for a scheduling request (SR), or a physical uplink control channel (PUCCH) for a configured grant, or a combination thereof As a result, the UE may transmit, to the base station, a message over the one or more resources allocated for the information based at least in part on identifying the one or more resources.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may request a user equipment (UE) to report location information for the UE using a specific format. The UE may report the location information to the base station based on the request. The base station may use the location information reported by the UE to determine the location of the UE.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a satellite of a non-terrestrial network (NTN) may establish communications on a beam of the satellite. The UE may receive, on a first carrier of a first set of carriers associated with a first beam, a configuration for the first set of carriers associated with the first beam and a second set of carriers associated with a second beam. The first carrier may be used to send a first set of synchronization signals, and a second carrier of the second set of carriers may be used to send a second set of synchronization signals. The UE may identify some system information associated with the second set of carriers based on the configuration and reselect to the second beam based on the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine an inactivity timer associated with a first set of one or more beams used for communicating with a network entity associated with a satellite has expired. The UE may identify location information corresponding to the location of the UE with respect to the network entity. The UE may identify beam geometry information for one or more beams associated with the network entity. For example, the UE may receive the beam geometry information from the network entity. The UE may process the location information and the beam geometry information to identify a second set of one or more beams, the second set different than the first set. The UE and the network entity may communicate according to the second set of one or more beams.

Abstract: Methods, systems, and devices for wireless communications are described. A narrowband internet of things (NB-IoT) user equipment (UE) associated with a non-terrestrial wireless network may identify a first synchronization procedure that is specific to the non-terrestrial network and different from synchronization procedures specific to terrestrial networks. In some cases, the UE may identify a different channel raster or may receive an indication of a true frequency of operation of a narrowband cell in the non-terrestrial network. The UE may identify the narrowband cell associated with the non-terrestrial network and may synchronize with the network using the identified synchronization procedure.

Abstract: Methods, systems, and devices for wireless communications are described that support multiplexing multicast and unicast feedback. A base station may provision different subsets of resources from a set of resources for multicast feedback message transmission based on channel metric(s) of a user equipment (UE). The set of resources may include a plurality of subsets of resources, with each subset of resources being associated with a corresponding channel metric or range of channel metrics associated with each UE receiving the multicast transmission. A UE may determine that a feedback indication is to be provided in response to the multicast transmission, and select a subset of resources from the plurality of subsets of resources based on its own channel metric. The UE may multiplex the multicast feedback, an indication of the selected subset, and unicast feedback in a multiplexed feedback transmission to the base station.

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 which a physical layer at a user equipment (UE) or a base station may generate feedback for one or more communications that are attempted to be received from a transmitting device. The physical layer feedback may be communicated to the transmitting device in higher layer communications, such as in a medium access control (MAC) layer control element (CE), where the MAC layer is a higher layer than the physical layer in a multi-layer protocol stack of the UE and base station. The physical layer feedback may be communicated after being triggered by one or more conditions at the UE or base station.

Abstract: A method for wireless communication includes validating a PUR configuration in a NTN based on location-related information associated with a satellite. For example, a UE may determine, based on location-related information of a satellite in a non-terrestrial network, whether a preconfigured uplink resource (PUR) configuration is valid. The UE may also transmit, to a base station (BS) via the satellite in response to determining that the PUR configuration is valid, a communication signal in a PUR. For example, the UE may determine, based on the location-related information associated with the satellite, if the parameter satisfies the threshold, and transmit UL data in a PUR occasion based on the determined parameter satisfying the threshold.
