Abstract
Provided is a terminal which appropriately transmits and receives signals when operating in an unlicensed band. A terminal (200) is provided with: a mapping unit (207) for allocating a signal to a resource on the basis of control information indicating allocation of groups among a plurality of groups obtained by grouping a plurality of blocks into which a frequency band has been divided, and allocation of resources in the blocks; and a transmitting unit (209) for transmitting the signal.
Claims10
A communication apparatus comprising:
- circuitry, which, in operation, receives control information including a first resource assignment information;
- and
- a transmitter, which, in operation, transmits to a base station a signal on resources determined based on the first resource assignment information,
- wherein the first resource assignment information indicates a set of one or more interlace indices, each of which indicating a plurality of resource blocks with a determined interval in a frequency domain,
- wherein, for a first subcarrier spacing, the first resource assignment information indicates a starting interlace index and a number of contiguous interlace indices, and
- wherein, for a second subcarrier spacing larger than the first subcarrier spacing, the first resource assignment information includes a bitmap indicating the set of one or more interlaces.
A communication method performed by a communication apparatus comprising:
- receiving control information including a first resource assignment information;
- and
- transmitting to a base station a signal on resources determined based on the first resource assignment information,
- wherein the first resource assignment information indicates a set of one or more interlace indices, each of which indicating a plurality of resource blocks with a determined interval in a frequency domain,
- wherein, for a first subcarrier spacing, the first resource assignment information indicates a starting interlace index and a number of contiguous interlace indices, and
- wherein, for a second subcarrier spacing larger than the first subcarrier spacing, the first resource assignment information includes a bitmap indicating the set of one or more interlaces.
