1. An apparatus for wireless communication at a base station, comprising:
memory; and
at least one processor coupled to the memory and configured to:
transmit a scheduling physical downlink control channel (PDCCH) transmission indicating a first beam specific transmission parameter for transmission of system information on a first beam of a cell and a second beam specific transmission parameter for transmission of the system information on a second beam;
transmit the system information of the cell on the first beam based on the first beam specific transmission parameter; and
transmit the system information of the cell on the second beam based on the second beam specific transmission parameter, wherein the system information of the cell is transmitted using different transmission parameters that provide different beam specific levels of coverage for the system information on the first beam and the system information on the second beam, wherein a transmission parameter of the system information of the cell is based on a respective beam from a plurality of beams used for transmitting the system information to provide the different beam specific levels of coverage for different directions, and wherein the second beam specific transmission parameter for the system information on the second beam increases the coverage for the system information transmitted on the second beam in comparison to the coverage for the system information transmitted on the first beam.
 
11. A method of wireless communication at a base station, comprising:
transmitting a scheduling physical downlink control channel (PDCCH) transmission indicating a first beam specific transmission parameter for transmission of system information on a first beam of a cell and a second beam specific transmission parameter for transmission of the system information on a second beam;
transmitting the system information of the cell on the first beam based on the first beam specific transmission parameter; and
transmitting the system information of the cell on the second beam based on the second beam specific transmission parameter, wherein the system information of the cell is transmitted using different transmission parameters that provide different beam specific levels of coverage for the system information on the first beam and the system information on the second beam, wherein a transmission parameter of the system information of the cell is based on a respective beam from a plurality of beams used for transmitting the system information to provide the different beam specific levels of coverage for different directions, wherein the second beam specific transmission parameter for the system information on the second beam increases the coverage for the system information transmitted on the second beam in comparison to the coverage for the system information transmitted on the first beam.
 
12. The method of claim 11, further comprising:
repeating transmission of the system information of the cell on the second beam based on the second beam specific transmission parameter.
 
14. An apparatus for wireless communication at a user equipment (UE), comprising:
memory; and
at least one processor coupled to the memory and configured to:
receive a scheduling physical downlink control channel (PDCCH) transmission including information for system information of a cell on one or more of a plurality of beams including a first beam specific transmission parameter for transmission of the system information on a first beam of the cell and a second beam specific transmission parameter for transmission of the system information on a second beam; and
monitor for the system information of the cell on a beam based on a transmission parameter associated with the beam, wherein the system information of the cell on different beams are associated with different transmission parameters that provide different levels of coverage for the system information in different directions, and wherein the second beam specific transmission parameter increases the coverage for the system information transmitted on the second beam in comparison to at least the first beam of the plurality of beams.
 
19. The apparatus of claim 14, wherein the information indicates a type of the transmission parameter that increases the coverage for the beam.
