Terminal and communication method
A terminal including a receiving unit configured to perform sensing of resource reservation information and resource allocation information transmitted from another terminal by using a sensing window; a control unit configured to determine an available resource set, by identifying a predetermined resource in a resource selection window, based on the resource reservation information and the resource allocation information; and a transmitting unit configured to execute transmission to the another terminal by using a resource selected from the resource set.
1. A terminal comprising:
a processor configured to select a specific number of slots in a specific time interval, to determine, based on a specific slot from among the selected specific number of slots, at least one of a periodic first time interval for performing a first partial sensing or a second time interval for performing a second partial sensing, and to determine, based on at least one of a first result of the first partial sensing or a second result of the second partial sensing, a set of resources usable within the selected specific number of slots; and
a transmitter configured to perform transmission to another terminal by using a resource selected from the set of resources,
wherein the first partial sensing is a partial sensing for a periodic traffic, and the processor determines the first time interval based on a slot located an integral multiple of a specific period before the specific slot from among the selected specific number of slots, and
wherein the processor determines the specific period based on a parameter transmitted from a base station to the terminal or a preconfigured parameter.
2. The terminal as claimed in claim 1 , wherein
the processor determines, based on the specific slot from among the selected specific number of slots, the first time interval and the second time interval, and determines the set of resources based on the first result of the first partial sensing and the second result of the second partial sensing.
3. The terminal as claimed in claim 1 , wherein
the second partial sensing is a partial sensing for an aperiodic traffic, and
the processor determines the second time interval based on a slot located a predetermined number of slots before the specific slot from among the selected specific number of slots.
4. The terminal as claimed in claim 1 , wherein
the processor determines the specific number of slots based on a parameter transmitted from a base station to the terminal or a preconfigured parameter.
5. The terminal as claimed in claim 1 , wherein
when the processor performs at least one of pre-emption or re-evaluation for the selected resource, the processor controls execution of at least one of the first partial sensing or the second partial sensing.
6. The terminal as claimed in claim 5 , wherein
when the processor performs at least one of pre-emption or re-evaluation for the selected resource, the processor controls execution of at least one of the first partial sensing or the second partial sensing.
7. A communication method performed by a terminal, the communication method comprising:
selecting a specific number of slots in a specific time interval, determining, based on a specific slot from among the selected specific number of slots, at least one of a periodic first time interval for performing a first partial sensing or a second time interval for performing a second partial sensing, and determining, based on at least one of a first result of the first partial sensing or a second result of the second partial sensing, a set of resources usable within the selected specific number of slots; and
performing transmission to another terminal by using a resource selected from the set of resources,
wherein the first partial sensing is a partial sensing for a periodic traffic, and the terminal determines the first time interval based on a slot located an integral multiple of a specific period before the specific slot from among the selected specific number of slots, and
wherein the terminal determines the specific period based on a parameter transmitted from a base station to the terminal or a preconfigured parameter.
