Claim:
A method for canceling interference signals brought by introducing P2P (Peer to Peer) communication in wireless communication systems, performed by a network system, comprising: (i) receiving a call request from a user equipment in a cell for communicating in UP-UTRAN-DOWN mode, wherein the requesting user equipment is hereinafter referred to as the requesting UE; (ii) judging whether there is an appropriate link timeslot, for which the requesting UE can share a same timeslot with a P2P user equipment allocated with radio resources in the cell, from among several available timeslots for the requesting UE to avoid being interfered by P2P signals transmitted by P2P communicating user equipments allocated with radio resources in a corresponding appropriate shared timeslot when the requesting UE communicates in the appropriate shared timeslot, according to the relative position of the requesting UE and the P2P communicating user equipments in P2P communication in the cell; and (iii) approving the call request from the requesting UE and allocating the appropriate shared timeslot to the requesting UE if the appropriate timeslot is available for sharing.
