Resource allocation method and apparatus

A base station comprising:

• a processor configured to determine a resource allocation type and a first physical resource to be allocated to a terminal, the terminal supporting a new system carrier and the new system carrier comprising a component carrier and an extension carrier,
• wherein the processor is further configured to determine, according to the resource allocation type and a mapping relationship between a resource block unit and a physical resource, a first resource block unit corresponding to the first physical resource,
• wherein the resource block unit is a resource allocation granularity in which the base station allocates a resource to the terminal,
• wherein the mapping relationship comprises a first mapping relationship and a second mapping relationship,
• wherein the first mapping relationship is a mapping relationship obtained by mapping a resource block unit occupied by a first part of the component carrier to a physical resource occupied by the first part of the component carrier according to the resource allocation type and a bandwidth of the first part of the component carrier,
• wherein the second mapping relationship is a mapping relationship obtained by mapping a resource block unit occupied by a first extension carrier to a physical resource occupied by the first extension carrier according to the resource allocation type, and wherein the first extension carrier comprises the extension carrier and a remaining part of the component carrier;
• and
• a transmitter configured to send resource allocation information to the terminal, wherein the resource allocation information comprises the resource allocation type and indication information of the first resource block unit allocated by the base station to the terminal.

A terminal comprising:

• a transceiver configured to receive resource allocation information from a base station, wherein the terminal supports a new system carrier, wherein the new system carrier comprises a component carrier and an extension carrier, and wherein the resource allocation information comprises a resource allocation type and indication information of a first resource block unit allocated by the base station to the terminal;
• and
• a processor configured to determine, according to the resource allocation information and a mapping relationship between a resource block unit and a physical resource, a first physical resource corresponding to the first resource block unit allocated by the base station to the terminal,
• wherein the mapping relationship comprises a first mapping relationship and a second mapping relationship,
• wherein the first mapping relationship is a mapping relationship obtained by mapping a resource block unit occupied by a first part of the component carrier to a physical resource occupied by the first part of the component carrier according to the resource allocation type and a bandwidth of the first part of the component carrier,
• wherein the second mapping relationship is a mapping relationship obtained by mapping a resource block unit occupied by a first extension carrier to a physical resource occupied by the first extension carrier according to the resource allocation type, and wherein the first extension carrier comprises the extension carrier and a remaining part of the component carrier.
