摘要： The present disclosure relates to a method of managing a configured grant timer related to a Hybrid automatic repeat request (HARQ) process associated with a configured grant by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving a retransmission grant for the HARQ process with starting the configured grant timer related to the HARQ process; based on a HARQ buffer of the HARQ process not being empty, performing a transmission for the HARQ process based on the retransmission grant with restarting the configured grant timer related to the HARQ process; and based on the HARQ buffer of the HARQ process being empty, stopping the configured grant timer related to the HARQ process.

摘要： A transmission method includes creating an automatic repeat request process for a first packet; setting a lifetime for the automatic repeat request process; and sending the first packet; and when a preset retransmission condition in the lifetime of the automatic repeat request process is satisfied, retransmitting a second packet; where the preset retransmission condition includes that at least part of the time instants within the first predetermined time interval after an incorrect-reception acknowledgement frame returned by the receiver is received is beyond the lifetime of the automatic repeat request; where retransmitting the second packet includes: extending the lifetime of the automatic repeat request process to a third predetermined time interval following the first predetermined time interval, where the third predetermined time interval is at least a time period required for retransmitting the second packet; and retransmitting the second packet after the first predetermined time interval.

摘要： Example techniques for data retransmission in systems that do not utilize explicit hybrid automatic repeat request (HARQ) feedback are presented, including an example method by a wireless device that includes starting a timer for a hybrid automatic repeat request (HARQ) process associated with a transport block (TB) transmission by the wireless device to the network node. The method includes identifying a HARQ policy for the HARQ process, the HARQ policy governing whether the wireless device is to retransmit the TB or transmit a new TB where no HARQ feedback responsive to the TB transmission is received from the network node before the timer expires. Furthermore, the method includes retransmitting the TB or transmitting the new TB according to the HARQ policy at a next periodic transmission occasion for the HARQ process after the timer expires. Methods at a network node and related apparatuses and computer programs are also presented.

摘要： The disclosure provides a method for sidelink channel state information (CSI) reporting in a wireless communication system. The method comprises steps in which: a user equipment (UE) obtains parameters associated with discontinuous reception (DRX); the UE transmits, to a peer UE, a CSI request; and the UE monitors a sidelink channel in an active time of the DRX for receiving, from the peer UE, sidelink CSI in response to the CSI request, wherein the active time of the DRX includes a time duration between transmitting the CSI request and receiving the sidelink CSI.

摘要： Aspects relate to feedback such as HARQ-ACK/NACK feedback in wireless communication systems. A predetermined condition, such as a timeout condition, is configured for a user equipment (UE) to determine whether a HARQ-less feedback should be implemented in the UE. In a particular aspect, the predetermined condition may be a timeout period or some other condition where a UE will cancel or discard feedback if the UE is unable to respond within the timeout period or meet the condition imposed. Various conditions may be imposed and are communicated through either radio resource control (RRC) signaling or downlink control information (DCI) parameters, or a combination thereof.

摘要： According to certain embodiments, a method in a wireless device (110) includes transmitting a protocol data unit (PDU) or segment of a PDU on a first link and transmitting the PDU or the segment of the PDU on a second link. One or more retransmissions of the PDU or the segment of the PDU are scheduled on the second link. A positive acknowledgment is received from a receiver. The positive acknowledgement indicates a successful receipt of the PDU or the segment of the PDU on the first link. In response to receiving the positive acknowledgement, the one or more retransmissions of the PDU or the segment of the PDU on the second link are cancelled.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may start a timer after transmitting an uplink communication on a physical uplink shared channel to a base station using a configured grant. The UE may determine whether the uplink communication is acknowledged as received by the base station based at least in part on determining whether a downlink communication from the base station is detected within a time duration associated with the timer. Numerous other aspects are provided.
