    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing dynamic power control with minimal complexity in a dual connectivity mode. In particular, a user equipment (UE) may determine the reserved power (or maximum available power) for uplink transmissions on one or more cells in one cell group to a base station based on the total power available to the UE and the minimum reserved power for uplink transmissions on one or more cells in another cell group. Once the UE determines the reserved power for conflicting uplink transmissions on one or more cells in a cell group, the UE may allocate the reserved power to each uplink transmission on the one or more cells in the cell group (e.g., based on a priority of each of the uplink transmissions).

    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 user equipment (UE) may receive an indication of a codebook type for transmitting hybrid automatic repeat request (HARQ) feedback by the UE to a second device (e.g., a network device, a satellite, or a base station). The indication of the codebook type may indicate a HARQ feedback transmission configuration, such as a static HARQ feedback transmission configuration. The HARQ transmission configuration may be associated with a one bit or two bit HARQ codebook. The UE may receive a scheduled downlink shared channel transmission, and attempt to decode the received downlink shared channel transmission. The UE may transmit (or refrain from transmitting) the HARQ feedback based on the decoding of the scheduled downlink shared channel transmission and in accordance with the feedback mode.

    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).

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide a mechanism for a user equipment (UE) to identify an uplink transmit beam to be used for communicating with a base station. In some cases, the uplink transmit beam may be based on a recent uplink (or downlink) transmission or set of allocated resources. A base station may allocate communication resources for a UE. The UE may determine, based on the allocated communication resources, a default transmit beam for communicating with the base station. The UE and base station may (e.g., independently) identify a triggering condition for using the default transmit beam. The UE may transmit an uplink communication to the base station using the default transmit beam based on the triggering condition.
