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: A method for wireless communication at a user equipment (UE) includes receiving, from a base station, a slot parameter that configures the UE to receive a number of symbols within a self-contained slot. The method also includes receiving, from the base station, a cyclic prefix (CP) parameter associated with a single symbol of the number of symbols, the CP parameter indicating a source of samples for a CP included at a beginning of the single symbol. The method further includes receiving, from the base station, the number of symbols within the self-contained slot. In some examples, a guard interval (GI) may be included at one or both of an end or a beginning of each symbol of the number of symbols. The CP may be outside a single FFT window of a number of FFT windows, associated with the single symbol of the number of symbols.

Abstract: Methods, systems, and devices for wireless communications are described in which control resources may be identified, and a data transmission may be rate-matched around the one or more control channels of multiple UEs or at multiple aggregation levels in the control resources. A user equipment (UE) may identify a search space for a first control channel, and the rate-matching of the data transmission may be performed based on a location of the search space in the control resources. In some cases, a base station may provide a mapping of resources (e.g., a bitmap) within the control resources that are occupied, which may be used for rate-matching.

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 communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a set of frequency domain resources allocated to the UE for communicating data over a wireless channel. The UE may receive an indication of a waveform type associated with the set of frequency domain resources. The waveform type may be based at least in part on a data type of the data, may be used for a defined amount of time, and may be one of a plurality of waveform types that are multiplexed together over different frequency domain resources within a total system bandwidth. The UE may communicate within the set of frequency domain resources according to the indicated waveform type and the data type.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure a set of transmission parts each including different sets of time domain resources or different sets of frequency domain resources, or both, and may specify a waveform type for each of the set of transmission parts. In some examples, the base station may configure the set of transmission parts for a user equipment (UE) and, accordingly, the UE and the base station may communicate over a transmission part of the set of transmission parts via signaling that is based on a waveform type that is associated with the transmission part over which the UE and the base station communicate. The base station may control over which transmission part of the set of transmission parts the UE and the base station communicate via a configured timer or via explicit activation and deactivation signaling.

Abstract: Methods, systems, and devices for radio link management are described. In a first example, a user equipment (UE) and a base station may employ a procedure for configuring radio link monitoring reference signals (RLM-RS) for multiple bandwidth parts. In a second example, a UE and a base station may employ a beam failure recovery procedure. In a third example, a UE and a base station may employ one or more radio link failure detection procedures. In a fourth example, a UE and a base station may employ a procedure for establishing a new connection after radio link failure. In a fifth example, a UE and a base station may employ a monitoring procedure that involves a single RLM-RS across multiple bandwidth parts.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may transmit, to a base station, an indication of a capability of the UE to switch from monitoring a set of frequency resources according to a first subcarrier spacing (SCS) to monitoring the set of frequency resources according to a second SCS, less than the first SCS. The indication may indicate an amount of time for the UE to switch between SCSs. The UE may receive, from the base station, signaling that indicates a configuration for monitoring the set of frequency resources according to the second SCS (e.g., a configuration for a reduced SCS window). The UE may switch from monitoring the set of frequency resources according to the first SCS to monitoring the set of frequency resources according to the second SCS based on receiving the configuration for monitoring the set of frequency resources.

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.
