Abstract: Methods, systems, and devices for wireless communications are described in which random access preambles may be designed to provide for relatively low inter-carrier interference (ICI) of adjacent available frequency resources in a non-terrestrial network (NTN). Random access preambles for NTN random access requests may be selected from a first set of random access preambles that are different from a second set of random access preambles for terrestrial random access requests.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives one or more downlink signals using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, selects a set of frequency resources for transmitting feedback information associated with the one or more downlink signals, and transmits the feedback information to the base station using the selected set of frequency resources. In some examples, the UE transmits one or more uplink signals to a base station using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, and determines whether to send a retransmission of the one or more uplink signals based at least in part on switching.

In some aspects, a user equipment may receive an indication of a set of interfered frequency resources that are subject to interference by a set of interfering frequency resources and communicate with a wireless communication device using at least one of: a bandwidth part configuration that is based at least in part on the set of interfered frequency resources, a communication procedure that is based at least in part on the set of interfered frequency resources, or a combination thereof. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for managing transmissions using multiple component carriers (CCs) in which transmissions using one or more of the CCs may span less than a full transmission time of a slot or other transmission time interval. A UE may signal a capability to transmit such transmissions, and one or more capabilities related to carrier aggregation that may be used by a base station for scheduling of transmissions on different CCs. In the event that overlapping transmissions on two or more CCs exceed a maximum power threshold, various techniques for dropping at least a portion of one or more transmissions of one or more CCs are described.

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 communication are described. In aspects of the present disclosure, a user equipment (UE) may report metrics (e.g., received signal power, beam identifier) about synchronization signal (SS) beams using the same (e.g., or a similar) framework that is used for channel state information reference signal (CSI-RS) reporting. Because SSs are intended to be broadcast across a wide coverage area in a beamformed manner, the SSs represent a promising complement to existing beam management techniques. Accordingly, beam management may be achieved at least in part based on reporting one or more metrics of beamformed SSs through a channel feedback framework.

The UE may report whether the UE is capable of combining the NRS with another signal to determine a combined signal quality parameter, and may report the combined signal quality parameter to a base station.

Abstract: A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. A BS and a UE may communicate using a narrowband Internet of Things (NB-IoT) communication system. However, a frequency, time, and/or power associated with transmission of a SIB1-NB on a non-anchor carrier may not be configured for NB-IoT. In some aspects, the BS may determine parameters, such as a time domain location parameter, a frequency domain location parameter, a quantity of repetitions, a power boosting parameter, and/or the like for a transmission in NB-IoT. In some aspects, a UE may determine to transmit a connection request message on a different carrier than a random access channel message.

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: Certain aspects of the present disclosure provide techniques for synchronization signal block (SSB) transmission in different frequency intervals. A method that may be performed by a user equipment (UE) includes receiving a first SSB from an entity in a non-terrestrial network (NTN) at a first time and frequency location. The method generally includes determining one or more time and frequency locations of one or more other SSBs from the entity in the NTN based on the first time and frequency location. The method generally includes monitoring for the one or more other SSBs at the determined one or more time and frequency locations.

Abstract: A self-learning, self-healing database-management system determines that erroneous input, such as an improper SQL query, has caused a critical database condition. The system parses each input statement into a set of tokens, and then translates each set into lines of a failure script. The script is consolidated by cross-referencing each line to infer relationships between input statements. The system then searches historical database logs for previously entered, error-free input similar to the erroneous input. A degree of similarity between the erroneous input and each previously entered input is determined by a computational method that quantifies similarities between the failure script and each script generated from a previously entered input. The system revises the erroneous input to more closely match the most-similar previously entered input and resubmits the corrected input. The results of the resubmission are used to train the system to more accurately correct future input errors.
