Method and the system in order to maintain the uplink same period which accompanies the Pia two Pia communication with radio communication

摘要

Being method in order to maintain the uplink same period which accompanies the P2P communication with radio communication network, obahiya which was transferred the aforementioned radio communication system, 2 UE (the user equipment) at the time of step and P2P communicating which obahiya it does P2P communication between by each UE on the basis of the information which is done step and UE which it transmits to UE which corresponds SS the description above UE (synchronous shift) step and this SS information which decide information, through the down link common control channel, the SS information which was transferred through step and the down link common control channel which watch the down link common control channelOf on the basis, TA in order to transmit the signal (timing advance) the method of including with the step which is adjusted is proposed.
