Abstract
A method and an apparatus for transmitting and receiving resource allocation information in a wireless communication system are provided. The method includes allocating resources for each of one or more device-to-device (D2D) discovery resources pools, generating information related to resources allocated for each of the one or more D2D discovery resource pools, and transmitting the generated information.
Claims18
A method of a base station (BS) in a communication system, the method comprising:
- identifying a discovery resource interval (DRI) and a number of discovery subframes in the DRI;
- generating discovery resource configuration information indicating resources used for discovery, the discovery resource configuration information including information indicating the DRI, the number of discovery subframes in the DRI, subframe bitmap information, repetition information, and physical resource block (PRB) information;
- and
- transmitting the discovery resource configuration information,
- wherein the DRI indicates a duration for allocating of the resources,
- wherein the subframe bitmap information indicates at least one of the discovery subframes which is used for the discovery,
- wherein the repetition information indicating a number of times a bitmap occurs within the duration for allocating of the resources,
- wherein the PRB information is related to a PRB on a subframe for the discovery in the duration for the allocating of the resources, and includes a PRB start index and a PRB end index, and
- wherein the discovery resource configuration information is transmitted in a downlink shared channel (DL-SCH).

A method of a user equipment (UE) in a communication system, the method comprising:
- receiving discovery resource configuration information indicating resources used for discovery;
- identifying information indicating a discovery resource interval (DRI), a number of discovery subframes in the DRI, subframe bitmap information, repetition information, and physical resource block (PRB) information from the discovery resource configuration information;
- and
- performing discovery based on the identified information,
- wherein the DRI indicates a duration for allocating of the resources,
- wherein the subframe bitmap information indicates at least one of the discovery subframes which is used for the discovery,
- wherein the repetition information indicating a number of times a bitmap occurs within the duration for allocating of the resources,
- wherein the PRB information is related to a PRB on a subframe for the discovery in the duration for the allocating of the resources, and includes a PRB start index and a PRB end index, and
- wherein the discovery resource configuration information is received in a downlink shared channel (DL-SCH).
6 more elements
A base station (BS) in a communication system, the BS comprising:
- at least one processor configured to:

- and
- a transceiver configured to transmit the discovery resource configuration information,
- wherein the DRI indicates a duration for allocating of the resources,
- wherein the subframe bitmap information indicates at least one of the discovery subframes which is used for the discovery,
- wherein the repetition information indicating a number of times a bitmap occurs within the duration for allocating of the resources,
- wherein the PRB information is related to a PRB on a subframe for the discovery in the duration for the allocating of the resources, and includes a PRB start index and a PRB end index, and
- wherein the discovery resource configuration information is transmitted in a downlink shared channel (DL-SCH).
