    Abstract: Methods, systems, and devices for scrambling initialization indication for higher bands are described. For example, a user equipment (UE) may receive a synchronization signal block (SSB) from a base station, the SSB including a primary synchronization signal (PSS), a data payload, and a demodulation reference signal (DMRS). The UE may identify a first part of a cell identifier (ID) of the base station, a second part of the cell ID, or both, indicated in a sequence of the DMRS, indicated in the data payload, or a combination thereof. The UE may monitor for a message from the base station based on identifying the cell ID.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a subcarrier spacing (SCS) for communications in a transmission time interval (TTI), such as a half-subframe, including multiple symbols, corresponding cyclic prefixes, and a padding duration which is at least as long as a symbol duration. The UE may receive a configuration for the padding duration, indicating that at least a portion of the padding duration is reallocated for a reference signal that indicates waveform parameters for one or more symbols of the TTI after the padding duration. The UE may receive the reference signal indicating the waveform parameters during the portion of the padding duration and communicate during the one or more symbols of the TTI according to the waveform parameters.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing beam configurations and parameters for non-terrestrial networks. In some implementations, a UE may detect a synchronization signal block (SSB) transmitted by a satellite via a first beam. Aspects of the present disclosure recognize that each beam may be identified by a unique SSB index based at least in part on a time or frequency on which the SSB is received. Thus, the SSB may be identified based on a frequency-domain SSB index or a time-domain SSB index. The UE may further determine one or more wireless communication parameters associated with the first beam. The UE may generate a mapping between the SSB and the wireless communication parameters associated with the first beam, and thereafter communicate with the satellite using the mapping.

    Abstract: Methods, systems, and devices for wireless communications are described. A serving base station or a serving satellite may transmit a timing configuration to the UE based on a reference unit, such as a location at a beam center for a respective satellite, a threshold distance relative to the beam center for the respective satellite, a reference time, or any combination thereof. In some cases, the UE may monitor for one or more SSBs from the neighboring satellites according to the timing configuration and a respective propagation delay between the UE and each of the neighboring satellites. The UE may measure the SSBs according to the measurement gap and measurement window in the timing configuration. In some examples, the UE may perform a cell handover procedure or a cell reselection procedure based on measuring the SSBs.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station by initiating a random access procedure with a two-root preamble. The UE may receive, from the base station, control signaling that indicates a set of root preamble sequences. The UE may transmit, to the base station, a preamble signal that is generated based on a first root preamble sequence and a second root preamble sequence of the set of root preamble sequences. The UE may then monitor for a preamble response based on the preamble signal. In some cases, the base station may be a base station in a terrestrial network. In other cases, the base station may be a satellite in a non-terrestrial network (NTN).
