Abstract

A WTRU may be configured to perform logical channel prioritization. A WTRU may receive an indication (e.g., a mapping) that indicates an association between a first HARQ process ID and a first HARQ processing type and between a second HARQ process ID and a second HARQ processing type. The WTRU may receive an indication (e.g., a mapping) that indicates an association between a first logical channel and the first HARQ processing type and between a second logical channel and the second HARQ processing type. The WTRU may receive an a HARQ process ID indication. The WTRU may determine a HARQ processing type associated with the HARQ process ID. The WTRU may determine a logical channel available for a transmission. The logical channel available to be used may be determined based on the HARQ processing type associated with the HARQ process ID. The WTRU may send the transmission.

Dependent claims

A wireless transmit/receive unit (WTRU) comprising:

a processor, configured to:
receive configuration information comprising a first hybrid automatic repeat request (HARQ) behavior associated with a first HARQ identifier (ID) and comprising a second HARQ behavior associated with a second HARQ ID;
receive a downlink (DL) grant that indicates a HARQ ID, wherein the HARQ ID is the first HARQ ID or the second HARQ ID;
determine a HARQ behavior based on the indicated HARQ ID, wherein the HARQ behavior is determined to be the first HARQ behavior if the HARQ ID is the first HARQ ID, and wherein the HARQ behavior is determined to be the second HARQ behavior if the HARQ ID is the second HARQ ID;
and
send a transmission, wherein the transmission is associated with the determined HARQ behavior, wherein
on a condition that the HARQ behavior is determined to be the first HARQ behavior, the transmission comprises HARQ feedback, and
on a condition that the HARQ behavior is determined to be the second HARQ behavior, the transmission excludes HARQ feedback.
