Abstract
In user terminal 20, reception section 204 receives one or more downlink signals mapped to a plurality of signal transmission points in a single carrier, and extraction section 214 extracts at least one of the one or more downlink signals that is assigned to at least one of the signal transmission points that belongs to a resource block group associated with user terminal 20, in which the resource block group is in units of a predetermined number of signal transmission points and the at least one of the one or more downlink signals is extracted based on a definition of the resource block group. This processing makes it possible to multiplex downlink signals for a plurality of terminals in a single-carrier transmission.
Claims7
A terminal comprising:
- a receiver configured to receive a downlink signal within a symbol duration in a single carrier;
- and
- a processor configured to extract the downlink signal assigned to at least one of a plurality of resources within the symbol duration in a time domain,
- wherein the processor extracts the downlink signal based on a definition of a resource block group (RBG) within the symbol duration and the RBG comprising the at least one of a plurality of resources in the time domain and being associated with the terminal, and
- wherein the processor configures the RBG based on an RBG-configuration constraining condition, the RBG-configuration constraining condition being dependent on the symbol duration.
A radio communication method comprising:
- receiving a downlink signal within a symbol duration in a single carrier;
- and
- extracting the downlink signal assigned to at least one of a plurality of resources within the symbol duration in a time domain,
- wherein the downlink signal is extracted based on a definition of a resource block group (RBG) within the symbol duration and the RBG comprising the at least one of a plurality of resources in the time domain and being associated with a terminal, and
- wherein the method further includes configuring the RBG based on an RBG-configuration constraining condition, the RBG-configuration constraining condition being dependent on the symbol duration.
