Title:
端末、無線通信方法、基地局及びシステム
Document Type and Number:
Japanese Patent JP6917905
Kind Code:
B2
Abstract:
The present invention is designed to execute uplink transmission using an allocation method for an uplink resource suitable for a cell (for example, a cell in an unlicensed band) to which listening is applied before the transmission. The user terminal according to one aspect of the present invention receives downlink control information including allocation information for an uplink resource allocated by any one of a single cluster allocation (type 0) and an interlaced multi-cluster allocation (type 2). The single cluster allocation (type 0) is configured to allocate a single cluster to the user terminal. The interlaced multi-cluster allocation (type 2) is configured to allocate a transmission unit to the user terminal. The transmission unit is constituted of a plurality of clusters uniformly arranged in a frequency direction. The user terminal is configured to determine the uplink resource used to transmit an uplink shared channel based on the allocation information.
