Abstract
According to an embodiment of the present disclosure, a method for performing sidelink communication is provided. The method may include performing initial transmission to a second apparatus, performing at least one of first retransmission to the second apparatus, receiving HARQ NACK related to the initial transmission and the at least one of first retransmission from the second apparatus, and performing at least one of second retransmission to the second apparatus.
Claims10
A method for performing wireless communication by a first apparatus, the method comprising:
- determining distance between the first apparatus and a second apparatus;
- performing an initial transmission to the second apparatus;
- performing at least one first retransmission related to the initial transmission to the second apparatus;
- receiving hybrid automatic repeat request negative acknowledgement (HARQ NACK) related to the initial transmission or the at least one of first retransmission from the second apparatus;
- and
- performing at least one second retransmission to the second apparatus based on the reception of the HARQ NACK,
- wherein a number of the at least one first retransmission and a number of the at least one second retransmission are determined based on mapping information between the distance and a number of retransmissions, and
- wherein the mapping information includes information related to the number of retransmissions mapped for each distance interval less than or equal to minimum communication range.
A processing device adapted to control a first apparatus to perform wireless communication, the processing device comprising:
- at least one processor;
- and
- at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the at least one processor to perform operations comprising:
- determining distance between the first apparatus and a second apparatus;
- performing an initial transmission to the second apparatus;
- performing at least one first retransmission related to the initial transmission to the second apparatus;
- receiving hybrid automatic repeat request negative acknowledgement (HARQ NACK) related to the initial transmission or the at least one of first retransmission from the second apparatus;
- and
- performing at least one second retransmission to the second apparatus based on the reception of the HARQ NACK,
- wherein a number of the at least one first retransmission and a number of the at least one second retransmission are determined based on mapping information between the distance and a number of retransmissions, and
- wherein the mapping information includes information related to the number of retransmissions mapped for each distance interval less than or equal to minimum communication range.
A first apparatus adapted to perform wireless communication, the first apparatus comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the at least one processor to perform operations comprising:
- determining distance between the first apparatus and a second apparatus;
- performing initial transmission to the second apparatus;
- performing at least one first retransmission related to the initial transmission to the second apparatus;
- receiving hybrid automatic repeat request negative acknowledgement (HARQ NACK) related to the initial transmission or the at least one of first retransmission from the second apparatus;
- and
- performing at least one second retransmission to the second apparatus based on the reception of the HARQ NACK,
- wherein a number of the at least one first retransmission and a number of the at least one second retransmission are determined based on mapping information between the distance and a number of retransmissions, and
- wherein the mapping information includes information related to the number of retransmissions mapped for each distance interval less than or equal to minimum communication range.
