Terminal, radio communication system and radio communication method
A terminal is disclosed including a control unit that is capable of multiplexing a first uplink control information of a first priority and a second uplink control information of a second priority in an uplink control channel; and a communication unit that transmits an uplink signal via the uplink control channel, wherein the control unit determines a resource of the uplink control channel based on whether the first uplink control information is associated with the first uplink control information.
1 . A terminal comprising:
a processor that multiplexes a first uplink control information of a first priority and a second uplink control information of a second priority; and
a transmitter that transmits the first uplink control information and the second uplink control information via same uplink control channel,
wherein the processor determines a resource of the same uplink control channel based on most recent first downlink control information among a plurality of a first downlink control information associated with the first uplink control information,
wherein the processor determines a resource of the same uplink control channel from a resource set as a resource different from a resource that can be indicated by the first downlink control information when there is no first downlink control information associated with the first uplink control information, and
wherein the resource set as a different resource is a resource set by SPS-PUCCH-AN-List included in an RRC message.
2 . The terminal of claim 1 , wherein
the processor determines a resource specified by an identifier contained in the most recent first downlink control information from among resources in a resource set associated with the first uplink control information as a resource of the same uplink control channel.
3 . A radio communication system comprising:
a terminal; and
a base station, wherein
the terminal comprises:
a processor that multiplexes a first uplink control information of a first priority and a second uplink control information of a second priority; and
a transmitter that transmits the first uplink control information and the second uplink control information via same uplink control channel,
wherein the processor determines a resource of the same uplink control channel based on most recent first downlink control information among a plurality of a first downlink control information associated with the first uplink control information,
wherein the processor determines a resource of the same uplink control channel from a resource set as a resource different from a resource that can be indicated by the first downlink control information when there is no first downlink control information associated with the first uplink control information, and
wherein the resource set as a different resource is a resource set by SPS-PUCCH-AN-List included in an RRC message.
4 . A radio communication method comprising:
multiplexing a first uplink control information of a first priority and a second uplink control information of a second priority;
transmitting the first uplink control information and the second uplink control information via same uplink control channel; and
determining a resource of the same uplink control channel based on most recent first downlink control information among a plurality of a first downlink control information associated with the first uplink control information,
wherein the method further comprises determining a resource of the same uplink control channel from a resource set as a resource different from a resource that can be indicated by the first downlink control information when there is no first downlink control information associated with the first uplink control information, and
wherein the resource set as a different resource is a resource set by SPS-PUCCH-AN-List included in an RRC message.
