    Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify an intelligent reflecting surface device for communications with a user equipment. The base station may determine a reference signal configuration based on the identified intelligent reflecting surface device. The reference signal configuration may include a first set of parameters associated with the intelligent reflecting surface device. The base station may transmit, to the UE, the intelligent reflecting surface device, or both, one or more reference signals in accordance with the first set of parameters. The base station may identify a second set of parameters associated with one or more reflecting elements of the intelligent reflecting surface device.

    Abstract: Aspects relate to configuration of a Layer 1 (L1) measurement report. A radio access network (RAN) node (e.g., a base station) can transmit at least one report setting, each associated with a selected information type, to a wireless communication device (e.g., a UE). The selected information type may be selected from a first information type and a second information type. When a report setting is associated with the first information type, the wireless communication device can transmit the L1 measurement report including both beam measurements and beam identifiers corresponding to the beam measurements for the report setting. When the report setting is associated with the second information type, the wireless communication device can exclude the beam identifiers from the L1 measurement report including the beam measurements for the report setting. Other aspects, features, and examples are also claimed and described.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may account for propagation delay when initiating a random access (RACH) procedure. For example, the UE may determine transmission timing for a RACH preamble based on an estimated propagation delay, such that the RACH preamble is received at a base station approximately at the beginning of a slot. To support reliable communication of the RACH preamble, the UE may implement a timing offset. In some examples, the base station may configure the UE with the timing offset using system information. Alternatively, the UE may be pre-configured with the timing offset. By determining the transmission timing for the RACH preamble further based on the timing offset, the UE may ensure that the RACH preamble is received at the base station after a slot boundary (e.g., avoiding causing interference to communications in a previous slot).

    Abstract: This disclosure provides systems, methods and apparatus for communicating a satellite behavior change. In one aspect, a satellite identifies a satellite behavior change to occur for the satellite of a non-terrestrial network for cellular communications. The apparatus also signals the satellite behavior change to a user equipment serviced by the satellite. In another aspect, a user equipment obtains, from a satellite servicing the user equipment, a signaling of a satellite behavior change to occur for the satellite. The user equipment also adjusts one or more user equipment parameters for cellular communication based on the obtained signaling. The satellite behavior change may include a satellite attitude or a transmit power or coverage area of one or more satellite beams. The user equipment parameters may include satellite or beam selection or reselection to listen to paging information, satellite or beam handover parameters, or transmit power control parameters.
