Method and device for determining priority of HARQ feedback in NR V2X
摘要
說明書
For example, performing, by the UE, blind retransmission may include: transmitting, by the UE, a TB or a MAC protocol data unit (PDU) by setting a predefined HARQ feedback request field value in a SCI to a “NOT REQUESTED” state, if at least one of the following conditions is satisfied, although the TB or the MAC PDU transmitted by the UE includes data related to HARQ ENABLED LCH(s). In the present disclosure, HARQ ENABLED Logical Channel(s) (LCH(s)) related data may be a MAC PDU or a TB configured with a logical channel for which HARQ feedback is enabled. For example, performing, by the UE, blind retransmission may include: transmitting, by the UE, a TB or a MAC PDU by setting a predefined HARQ feedback request field value in a SCI to a “NOT REQUESTED” state, if at least one condition among the cases related to the questions in Table 7 (e.g., Question D2 to Question D8) is satisfied, although the TB or the MAC PDU transmitted by the UE includes data related to HARQ ENABLED LCH(s). For example, performing, by the UE, blind retransmission may include: transmitting, by the UE, a TB or a MAC PDU by setting a predefined HARQ feedback request field value in a SCI to a “NOT REQUESTED” state, if a PUCCH resource is not configured through a SL grant related to transmission of the TB or the MAC PDU, although the TB or the MAC PDU transmitted by the UE includes data related to HARQ ENABLED LCH(s). For example, performing, by the UE, blind retransmission may include: transmitting, by the UE, a TB or a MAC PDU by setting a predefined HARQ feedback request field value in a SCI to a “NOT REQUESTED” state, if a PSFCH resource is not configured for the resource pool, although the TB or the MAC PDU transmitted by the UE includes data related to HARQ ENABLED LCH(s).
