Indication of transmitted SS blocks
Methods, systems, and devices for wireless communication are described. A base station may determine a group set of at least one synchronization signal (SS) block group to be transmitted within a SS burst set. The base station may identify a group transmission configuration index associated with the group set, and then transmit the group transmission configuration index to a user equipment. The base station may also include an indication of which SS blocks in each transmitted SS block group are transmitted. A user equipment (UE) may determine transmitted SS blocks based on the group set index or the indication of which SS blocks in each transmitted SS block group are transmitted.
