Abstract
A wireless transmit/receive unit (WTRU) may receive a first batch of protocol data units (PDUs) of a PDU set and transmit the first batch of PDUs of the PDU set to a network entity. The WTRU may further receive a resend indication from the network entity for the first batch of PDUs of the PDU set. Based on a a time for retransmitting the first batch of PDUs and receipt of a second batch of PDUs of the PDU set, the WTRU may determine whether to retransmit the at least the portion of the first batch of PDUs and/or transmit the second batch of PDUs of the PDU set.
Claims16
A wireless transmit/receive unit (WTRU) comprising a processor configured to:
- receive, from an extended reality (XR) application, a first batch of protocol data units (PDUs) of a PDU set;
- transmit the first batch of PDUs of the PDU set to a network entity;
- receive a resend indication from the network entity for the first batch of PDUs of the PDU set;
- in response to a determination that time for retransmitting the first batch of PDUs has not expired and a second batch of PDUs of the PDU set have been received, retransmit at least a portion of the first batch of PDUs and transmit the second batch of PDUs of the PDU set;
- and
- in response to a determination that the time for retransmitting the first batch of PDUs has not expired and the second batch of PDUs of the PDU set have not been received, indicate to the network entity that the first batch of PDUs will not be retransmitted.
A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
- receiving, from an extended reality (XR) application, a first batch of protocol data units (PDUs) of a PDU set;
- transmitting the first batch of PDUs of the PDU set to a network entity;
- receive a resend indication from the network entity for the first batch of PDUs of the PDU set;
- in response to a determination that time for retransmitting the first batch of PDUs has not expired and a second batch of PDUs of the PDU set have been received, retransmitting at least a portion of the first batch of PDUs and transmitting the second batch of PDUs of the PDU set;
- and
- in response to a determination that the time for retransmitting the first batch of PDUs has not expired and the second batch of PDUs of the PDU set have not been received, indicating to the network entity that the first batch of PDUs will not be retransmitted.
