Abstract

The present disclosure relates to a pre-5^th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4^th-generation (4G) communication system such as long term evolution (LTE). A method and user equipment (UE) for transmitting and receiving discovery information in a wireless communication system supporting a proximity service are provided. The method for transmitting discovery information includes receiving, in a medium access control (MAC) layer, discovery information for discovery associated with the proximity service from a higher layer, generating, in the MAC layer, a MAC protocol data unit (PDU) including the received discovery information, and transmitting, in a physical (PHY) layer, a discovery signal including the generated MAC PDU.

Claims

1-29. -29. (canceled)

30. A method for transmitting discovery information by a user equipment (UE) in a wireless communication system supporting a proximity service, the method comprising:

receiving, in a medium access control (MAC) layer, discovery information for discovery associated with the proximity service from a higher layer;

generating, in the MAC layer, a MAC protocol data unit (PDU) including the received discovery information; and

transmitting, in a physical (PHY) layer, a discovery signal including the generated MAC PDU.

31. The method of claim 30, further comprising determining a resource to be used for transmission of the discovery information in the MAC layer.

32. The method of claim 30, wherein a protocol stack, included in the UE, for the discovery includes the MAC layer and the PHY layer.

33. The method of claim 30, wherein an internet protocol layer is not used for transmission of the discovery information.

34. The method of claim 30, wherein no MAC header is added to the MAC PDU.

35. The method of claim 30, wherein the discovery signal is transmitted using a specific subframe.

36. The method of claim 30, wherein transmission or reception between the UE and a base station is higher in priority than transmission of the discovery signal.

37. A user equipment (UE) for transmitting discovery information in a wireless communication system supporting a proximity service, the UE comprising:

a transmitter configured to transmit a signal; and

a controller configured to control to;

receive, in a medium access control (MAC) layer, discovery information for discovery associated with the proximity service from a higher layer;

generate, in the MAC layer, a MAC protocol data unit (PDU) including the received discovery information; and

transmit, in a physical (PHY) layer, a discovery signal including the generated MAC PDU.

38. The UE of claim 37, wherein the controller is further configured to determine a resource to be used for transmission of the discovery information in the MAC layer.

39. The UE of claim 37, wherein the protocol stack for the discovery includes the MAC layer and the PHY layer.

40. The UE of claim 37, wherein the controller is further configured not to use an internet protocol layer for transmission of the discovery information.

41. The UE of claim 37, wherein no MAC header is added to the MAC PDU.

42. The UE of claim 37, wherein the controller is further configured to control to transmit the discovery signal using a specific subframe.

43. The UE of claim 37, wherein transmission or reception between the UE and a base station is higher in priority than transmission of the discovery signal.

44. A method for receiving discovery information by a user equipment (UE) in a wireless communication system supporting a proximity service, the method comprising:

receiving, in a physical (PHY) layer, a discovery signal including a medium access control protocol data unit (MAC PDU), the discovery signal including discovery information for discovery associated with the proximity service;

extracting, from a MAC layer, the discovery information included in the received MAC PDU; and

forwarding, in the MAC layer, the extracted discovery information to a higher layer.

45. The method of claim 44, further comprising determining a resource to be used for reception of the discovery information in the MAC layer.

46. The method of claim 44, wherein a protocol stack, included in the UE, for the discovery includes the MAC layer and the PHY layer.

47. A user equipment (UE) for receiving discovery information in a wireless communication system supporting a proximity service, the UE comprising:

a receiver configured to receive a signal; and

a controller configured to control to;

receive, in a physical (PHY) layer, a discovery signal including a medium access control protocol data unit (MAC PDU), the discovery signal including discovery information for discovery associated with the proximity service;

extract, from a MAC layer, the discovery information included the received MAC PDU; and

forward, in the MAC layer, the extracted discovery information to a higher layer.

48. The UE of claim 47, wherein the controller is further configured to determine a resource to be used for reception of the discovery information in the MAC layer.

49. The UE of claim 47, wherein a protocol stack, included in the UE, for the discovery includes the MAC layer and the PHY layer.
