  • Patent number: 11690103
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a random access channel (RACH) occasion (RO) based on one or more channel quality thresholds, such as reference signal received power (RSRP) thresholds. A base station may determine a set of RO types for receiving RACH transmissions. The base station may determine a channel quality threshold for each RO type. The base station may broadcast a configuration indicating the RO types and the associated channel quality thresholds. The UE may receive the configuration and measure a channel quality between the UE and the base station. Based on the measured channel quality, the UE may determine which RO types are available based on the indicated channel quality thresholds, and select an RO for transmitting a RACH preamble to establish a connection with the base station based on the available RO types.
