IPC: H04W74/08
Filed: 2019-08-12
Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving, from a base station, one or more random access channel (RACH) configurations. The RACH configurations may allocate resources for a contention-based RACH procedure for accessing a wireless network. Based on the RACH configurations, the UE may determine a set of random access occasions for an association period. From the set of random access occasions, the UE may determine, for the association period, a subset of random access occasions associated with one or more synchronization signal block (SSBs) of a plurality of SSBs transmitted by the base station. Using the subset of random access occasions, the UE may transmit a random access sequence, including one or more repetitions to the base station to access the wireless network.
