Just configure the branch router for DHCP. In HQ router you need to make it the default DHCP router. Add the below command in HQ router. Its own IP is address1(primary) and second IP is of branch router. This will solve your problem.

Router(config-dhcp)# default-router

address [address2 ... address8]

(Specifies the IP address of the default router for a DHCP client.

One IP address is required, although you can specify up to 8 addresses in one command line.)
