Abstract
A transmission device that: allocates at least partially shared transmission parameters to at least a subset of a plurality of signals to which resource blocks are allocated, the resource blocks having at least partially overlapping frequency resources or time resources; and controls a transmission process of the plurality of signals based on the shared transmission parameters.
Claims14
A transmission device comprising:
- circuitry configured to
- allocate at least partially shared transmission parameters to at least some of a plurality of signals to which resource blocks are allocated, the resource blocks having at least partially overlapping frequency resources or time resources;
- control a transmission process of the plurality of signals based on the shared transmission parameters;
- and
- generate information indicating an interference target and transmit the information as downlink control information,
- wherein the circuitry allocates the same resource block as the shared transmission parameters, and
- wherein the circuitry allocates, to a signal having a high allocated power level, a resource block including a resource block allocated to another signal having a lower allocated power level than the high allocated power level of the signal as the shared transmission parameters.
4 more elements
A reception device including:
- circuitry configured to
- receive information indicating interference target by downlink control information;
- determine that at least partially shared transmission parameters are used in a signal addressed to another communication device to which resource blocks in which frequency resources or time resources allocated to a self-addressed signal at least partially overlap are allocated;
- and
- control an interference cancellation process on the signal addressed to the other communication device as a target based on a result of determination,
- wherein the circuitry is further configured to determine that at least partially shared transmission parameters are used in a signal addressed to another communication device based on a format of control information.
3 more elements
A transmission method performed by a processor, the transmission method including:
- allocating at least partially shared transmission parameters to at least some of a plurality of signals to which resource blocks are allocated, the resource blocks having at least partially overlapping frequency resources or time resources;
- controlling a transmission process of the plurality of signals using the allocated shared transmission parameters;
- and
- generating information indicating an interference target and transmit the information as downlink control information,
- wherein the transmission method further comprises allocating the same resource block as the shared transmission parameters, and
- wherein the transmission method further comprises allocating, to a signal having a high allocated power level, a resource block including a resource block allocated to another signal having a lower allocated power level than the high allocated power level of the signal as the shared transmission parameters.
