Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) configuration for SSBs that carry first synchronization information. The UE may receive a reference signal indicating second synchronization information that is reduced relative to the first synchronization information. The UE may measure the reference signal to obtain measurement information. The UE may transmit, in association with the measurement information, a communication. The UE may receive, based on the transmission of the communication, an SSB in accordance with the SSB configuration and the measurement of the reference signal. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described that provide for transmission of discovery reference signals (DRSs) by a network entity in an energy saving mode. A user equipment (UE) may measure the DRSs and identify one or more associated synchronization signal blocks (SSBs) that are to be requested. The UE may transmit a wake-up signal (WUS) that includes an identification of one or more requested SSBs, such as a codepoint or bitmap. The network entity may receive the WUS and transmit the requested SSBs.

Abstract: This disclosure provides methods, components, devices, and systems for enhancing the efficiency of random access channel (RACH) processes in wireless communication networks using beam-specific configurations. Some aspects more specifically relate to the utilization of beam-specific RACH parameters, such as synchronization signal block (SSB) reference signal received power (RSRP) thresholds, two-step RACH parameters, two-step RACH thresholds, physical uplink shared channel (PUSCH) RSRP thresholds, supplementary uplink (SUL) RSRP thresholds, and channel state information reference signal (CSI-RS) RSRP thresholds, to optimize RACH processes. In some examples, a UE obtains a beam-specific configuration including one or more of these beam-specific RACH parameters and a downlink reference signal from a network entity, and sends to the network entity a RACH message associated with the downlink reference signal based on the parameters. The beam-specific configuration considers the unique characteristics and conditions of each transmission beam direction, resulting in improved network energy savings and resource allocation.

Abstract: A method of wireless communication at a first network node is disclosed herein. The method includes performing beam training with a RIS-MT array, wherein the RIS-MT array is associated with a RIS array.
