Abstract: Methods, systems, and devices for wireless communications are described. A non-terrestrial network (NTN) device (e.g., a satellite, base station) may transmit, to a user equipment (UE), at a first frequency a synchronization signal block (SSB) that indicates a second frequency of a control resource set (CORESET) relative to the SSB, where the second frequency is based on one or more of: a CORESET bandwidth, a combination of a first parameter associated with a first portion of the SSB and a second parameter associated with a second portion of the SSB, or both. The UE may monitor the CORESET at the indicated second frequency for a downlink control channel transmission. The NTN device may transmit, to the UE, a downlink control channel transmission over the CORESET. The NTN device may transmit, to the UE, system information based on the downlink control channel transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network may establish communications over a directional beam. The UE may receive, from the network, a configuration of one or more channel sounding messages for one or more directional beams, where each directional beam of the one or more directional beams is associated with a set of narrowband carriers, and each of the one or more channel sounding messages being configured for transmission on a narrowband carrier of the set of narrowband carriers. The UE may determine a trigger for transmitting the one or more channel sounding messaged based at least in part on the configuration and transmit, to the network, the one or more channel sounding messages on respective narrowband carriers in accordance with the trigger and the configuration.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration of a set of synchronization signal blocks (SSBs) to be transmitted by a first base station or a second base station. In some cases, the UE may be served by the first base station and the UE may receive, from the first base station or the second base station, a message indicating that a transmission of at least one SSB of the set of SSBs is canceled and indicating resources for a signal (e.g., a reference signal, alternative SSB transmission) to be transmitted by the first base station or the second base station as an alternative to the canceled at least one SSB. The UE may receive, based on the received message from the first base station or the second base station, the signal using the indicated resources.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify, for a user equipment (UE), a configuration for receiving a set of downlink control information (DCI) messages on one or more layers of a set of layers of a downlink shared channel. The base station may transmit, to the UE, a first DCI message in a downlink control channel, where the first DCI message may schedule resources of the downlink shared channel for the set of piggybacking DCI messages. The UE may receive the first DCI message and identify the configuration for receiving the set of DCI messages on the one or more layers of the downlink shared channel. The UE may receive, from the base station, the set of DCI messages on the one or more layers of the downlink shared channel based on the identified configuration.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive, from a base station, a first downlink control information message in a downlink control channel, the first downlink control information message scheduling first resources of a downlink shared channel for a second downlink control information message. The UE may identify a first, UE-specific scrambling sequence for the second downlink control information message. The UE may receive, from the base station, the second downlink control information message based on the first scrambling sequence, the second downlink control information message scheduling second resources of the downlink shared channel for a data message. The UE may receive, from the base station, the data message in the second resources scheduled by the second downlink control information message.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may use enhanced techniques for determining whether a transmission is scheduled to include new data when a mode for reporting acknowledgment feedback is disabled for one or more hybrid automatic repeat request (HARQ) processes used by the receiving device. An enhanced technique may include increasing a quantity of bits used to convey an indication of whether a scheduled data transmission includes new data. An enhanced technique may include monitoring a duration between transmissions scheduled by different control messages based on a timing parameter that indicates a maximum time between transmissions of a data set and corresponding transmission including the data set.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication via a non-terrestrial network (NTN). In one aspect, a method for wireless communication includes initiating, by a user equipment (UE), a registration process with a network entity of an NTN to access the NTN. The method further includes transmitting, by the UE to the network entity, UE capability information of the UE. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described that support techniques for intra-satellite handover. The described techniques provide for handovers such that a user equipment (UE) may transition from communications with a satellite via a first frequency (or set of frequencies) to communications with the same satellite via a second frequency (or set of frequencies). A UE may determine relevant timing and/or configuration for the second frequency (or set of frequencies) prior to transitioning from communications via the first frequency (or set of frequencies). Thus, the UE may efficiently begin communications at a second frequency (or set of frequencies) that are different than the first frequency (or set of frequencies)—for example, without performing a random access procedure.

Abstract: Various aspects of the disclosure relate to allocating control signaling resources for multiple carrier scenarios. In an example implementation, N-to-1 mapping is used between forward link control signaling resource allocation indices (e.g., control channel elements) and return link control signaling resources (e.g., for ACK/NACK signaling) indices in each return link component carrier. A collision between forward link control signaling assignments for different user terminals (UTs) may occur when UT-specific search spaces overlap each other. Such a collision may be avoided, for example, by scheduling different UTs on different return link component carriers, scheduling return link grants instead of forward link grants, or scheduling a different forward link control signaling candidate that is associated with a different forward link control signaling resource allocation index.
