Transmitter, method and terminal for allocating resources, and method of receiving resource allocation information
View Patent ↗The present invention relates to resource allocation in a wireless communication system. Specifically, the method comprises: an encoding step in which a resource block or a resource block group generates a resource indication value (RIV) which is a transform of the length (L) and the offset (j) of a contiguous resource allocation region; and a transmission step in which the resource allocation information is transmitted to a terminal, wherein the resource allocation information is calculated by means of a prescribed mathematical equation.
1. A transmitting apparatus comprising:
a encoder to generate resource allocation information (RIV) converted from the length of a resource allocation region L and an offset thereof j, wherein the resource allocation region consists of contiguous resource blocks or block groups; and
a transmitter to transmit the resource allocation information to a terminal,
wherein the resource allocation information is calculated by the formula below,
RIV

5. A terminal comprising:
a receiver to receive resource allocation information (RIV) to which information about a resource allocation region is encoded, wherein the resource allocation region consists of contiguous resource blocks or block groups; and
a decoder to decode the resource allocation information so as to extract a length of a resource allocation region L and an offset thereof j,
wherein the resource allocation information is calculated by the formula below,
