"Communication" is too vague. Let's try to get into this a little bit so it's EASY and SIMPLE.
Approach every round with 2 communication options:
"I'm gonna..." (Tell the party or party member what you're going to do)
"Do this..." (Give direction if you are certain what someone should do -- or NOT do)
When you work as a team, every character will be doing this round by round.
I can't tell you how many times a battle went bad and afterwards everyone starts saying "Well I was sure we should fall back, but your character seemed so confident." "I thought you knew I'd be casting a fireball!" "If you would have stayed back and used your bow, I could have buffed you before your charge."
DEALING WITH THE FOG OF WAR:
Usually confusion results from being caught off guard or meeting a different threat than you were mentally prepared for. If you are confused or locked in indecision, Keep It Simple:
1) Get into a safe or advantageous position
and/or
2) Focus on protecting a character at risk.
For example: The best first action by the group may very well be for the wizard to cast a spell, but the fighter may have initiative. What should the fighter do? Charging off into battle may be stupid, but his options may seem limited. Delaying might seem smart, but he may not have any idea what the wizard will actually cast. He might waste his action by delaying. There's nothing wrong with having the fighter move directly in front of the Wizard to help shield him from attacks. It's even better if he combines this with the directive "Cast a web, wizard!"
