TD-SCDMA trunking communication cell using a macro diversity technique can effectively overcome the large scale fading and ensure quality of signal.First

in the absence of any measures networking based on macro diversity is analyzed in this paper

but the forward-link capacity will be reduced as increasing in the number of base stations.After analyzing the reasons for capacity loss

we further propose a way

which is synchronizing signals on separate ways and adjusting phase using Rake receiver in the terminal

then combinating signals though maximum ratio combination

and then sending to the user

forward-link capacity will increase greatly.
