Abstract
There is provided user equipment of a radio communication system that supports TTIs having a plurality of lengths and that includes a base station and the user equipment, the user equipment including an acquisition unit configured to acquire, from the base station, information indicating a plurality of UL resources which are allocated to a plurality of symbols included in a TTI having a predetermined length and with which a scheduling request can be transmitted; and a transmission unit configured to select a UL resource from the plurality of UL resources and transmit the scheduling request to the base station with the selected UL resource.
Claims7
A terminal comprising:
- a receiver that receives, from a base station, configuration information including a configuration that includes an assignment, by time division multiplexing, of a plurality of scheduling request (SR) resources within one slot, the configuration information indicating a plurality of SR resource candidates, and receives information indicating a number of SR transmissions within the slot;
- a processor that determines an SR resource for transmitting a SR based on the configuration information and stored one or more logical channels;
- and
- a transmitter that transmits, to the base station, the SR with the SR resource,
- wherein the receiver receives uplink scheduling control information,
- wherein the uplink scheduling control information includes a priority identifier related to the one or more logical channels, and
- wherein the processor determines whether uplink data on the one or more logical channels is transmitted based on the priority identifier related to the one or more logical channels.
A communication method by a terminal, the method comprising:
- receiving, from a base station, configuration information including a configuration that includes an assignment, by time division multiplexing, of a plurality of scheduling request (SR) resources within one slot, the configuration information indicating a plurality of SR resource candidates;
- receiving information indicating a number of SR transmissions within the slot;
- determining an SR resource for transmitting a SR based on the configuration information and stored one or more logical channels;
- and
- transmitting, to the base station, the SR with the SR resource,
- wherein the method further comprises receiving uplink scheduling control information,
- wherein the uplink scheduling control information includes a priority identifier related to the one or more logical channels, and
- wherein the determining determines whether uplink data on the one or more logical channels is transmitted based on the priority identifier related to the one or more logical channels.
A radio communication system comprising:
- a terminal;
- and
- a base station,
- wherein the terminal includes:

- a processor that determines an SR resource for transmitting a SR based on the configuration information and stored one or more logical channels;
- and
- a transmitter that transmits, to the base station, the SR with the SR resource,
- wherein the receiver receives uplink scheduling control information,
- wherein the uplink scheduling control information includes a priority identifier related to the one or more logical channels, and
- wherein the processor determines whether uplink data on the one or more logical channels is transmitted based on the priority identifier related to the one or more logical channels, and
- wherein the base station includes a transmitter that transmits the configuration information to the terminal.
