Abstract
Methods, systems, and devices for wireless communications are described. Generally, Generally, a base station may send to a user equipment (UE) a configuration message, which may include an indication of one or more CSI-RS resources and one or more random access occasion indices. The UE may identify one or more random access occasions associated with the UE based on the CSI-RS resources, the random access occasion indices for the UE, and a random access occasion index reset time. The random access occasion index rest time may be based on a fixed time period. The random access occasion index reset time may be based on a number of CSI-RS resources. In some examples, the random access occasion index reset time may be based on a number of actually transmitted synchronization signal blocks (SSBs).
