Setting Comfast CPE E313AC

Installing and Using OpenWrt Network and Wireless Configuration
1

I have a Comfast CPE E313AC dual polarized antenna 5.8Ghz.
I put openwrt 21.02.3 version.
I have setting:
eth0 and eth1 are set in the lan(br-lan) interface (static address 192.168.1.1)
radio0 connected to remote AP in client mode and set in wwan interface
eth1 connected to switch.
That works.
I want E313AC set as AP repeater (or bridge) wifi.
When I add a new sssid in AP mode (in lan interface) it is not set.
If I put it in the wwan interface, it drops the connection to the remote AP.
By the way, if I disable the connection to the remote AP, the new ssid works and clients can connect to it.
Can openwrt set something like that on a dual polarized antenna and how?

AFAIK it depends on hardware and drivers capabilities. On my router

iw list | grep "interface combinations" -A 3
	valid interface combinations:
		 * #{ managed, AP, mesh point } <= 8,
		   total <= 8, #channels <= 1
	HT Capability overrides:
3

I have:

    valid interface combinations:
             * #{ managed } <= 16, #{ AP, mesh point } <= 16, #{ IBSS } <= 1,
               total <= 16, #channels <= 1, STA/AP BI must match, radar detect widths: { 20 MHz (no HT), 20 MHz, 40 MHz, 80 MHz, 80+80 MHz, 160 MHz

What means STA/AP BI must match?

I have DHCP server enabled on the lan interface.

thanx.
