Abstract
A method and apparatus for performing a device-to-device (D2D) specific access control in a wireless communication system is provided. A user equipment (UE) receives D2D specific barring parameters from a network, and checks whether access to a cell is allowed according to the received D2D specific barring parameters. The D2D specific barring parameters may include a D2D specific barring factor and a D2D specific barring time.

A method for performing, by a user equipment (UE), a device-to-device (D2D) specific access control in a wireless communication system, the method comprising:
- receiving, by the UE from a network, D2D specific barring parameters which are used to check whether or not the UE performing a D2D transmission or a D2D reception is allowed to access a cell;
- performing, by the UE, the D2D transmission or the D2D reception;
- while performing the D2D transmission or the D2D reception, checking, by the UE, whether or not the UE is allowed to access the cell based on the received D2D specific barring parameters;
- if the checking reveals that the UE is allowed to access the cell, transmitting, by the UE, at least one of a random access preamble, a scheduling request (SR), a buffer status report (BSR) or a radio resource control (RRC) connection request, to the network;
- and
- if the checking reveals that the UE is not allowed to access the cell, barring, by the UE, transmission of the random access preamble, transmission of the SR, transmission of the BSR and transmission of the RRC connection request, to the network.
A user equipment (UE), comprising:
- a memory;
- a transceiver;
- and
- a processor, coupled to the memory and the transceiver, that:
- receives, from a network, D2D specific barring parameters which are used to check whether or not the UE performing a D2D transmission or a D2D reception is allowed to access a cell;
- performs the D2D transmission or the D2D reception;
- while performing the D2D transmission or the D2D reception, checks whether or not the UE is allowed to access the cell based on the received D2D specific barring parameters;
- if the checking reveals that the UE is allowed to access the cell, transmits at least one of a random access preamble, a scheduling request (SR), a buffer status report (BSR) or a radio resource control (RRC) connection request, to the network;
- and
- if the checking reveals that the UE is not allowed to access the cell, bars transmission of the random access preamble, transmission of the SR, transmission of the BSR and transmission of the RRC connection request, to the network.
