The wireless communication system may be characterized by a flexible air interface. One aspect of the flexible air interface is that transmissions by a wireless transmit/receive unit (WTRU) in the system may have different quality of service (QoS) requirements, such as different latency requirements. The WTRU may adjust its behaviors based on the QoS requirements, e.g., by utilizing preconfigured resources, resource requests, self-scheduling, and/or the like, such that the transmissions may be performed in accordance with their respective QoS requirements. ## Claims ### Claim 1 A wireless transmit/receive unit (WTRU), comprising: a processor configured to: receive information indicating an uplink transmission grant for the WTRU and a priority associated with the uplink transmission grant; determine that data associated with a first logical channel is available for transmission; determine that the priority associated with the uplink transmission grant matches a priority associated with the first logical channel; determine, based on the priority associated with the uplink transmission grant matching priority associated with the first logical channel, the data associated with the first logical channel is to be transmitted using the uplink transmission grant; and transmit the data associated with the first logical channel using the uplink transmission grant. ### Claim 2 (depends on 1) The WTRU of claim 1, wherein the processor is further configured to receive configuration information that indicates the priority associated with the first logical channel. ### Claim 3 (depends on 1) The WTRU of claim 1, wherein the determination that the data associated with the first logical channel is to be transmitted using the uplink transmission grant is based further on a determination that a subcarrier spacing associated with the uplink transmission grant is among one or more subcarrier spacings associated with the first logical channel. ### Claim 4 (depends on 1) The WTRU of claim 1, wherein the determination that the data associated with the first logical channel is to be transmitted using the uplink transmission grant is based further on a transmission timing parameter associated with the uplink transmission grant. ### Claim 5 (depends on 1) The WTRU of claim 1, wherein the processor is further configured to determine that data associated with a second logical channel is available for transmission and determine, based on at least the priority associated with the uplink transmission grant and a priority associated with the second logical channel, that the data associated with the second logical channel is not to be transmitted using the uplink transmission grant. ### Claim 6 (depends on 5) The WTRU of claim 5, wherein the processor is further configured to transmit a scheduling request (SR) to a base station in response to determining that the data associated with the second logical channel is not to be transmitted using the uplink transmission grant. ### Claim 7 (depends on 6) The WTRU of claim 6, wherein the SR is transmitted to the base station using one or more SR resources configured for the second logical channel. ### Claim 8 (depends on 7) The WTRU of claim 7, wherein the processor is further configured to receive configuration information that indicates the one or more SR resources configured for the second logical channel. ### Claim 9 (depends on 1) The WTRU of claim 1, wherein the information that indicates the uplink transmission grant and the priority associated with the uplink transmission grant is received via a downlink control channel. ### Claim 10 A method implemented by a wireless transmit/receive unit (WTRU), the method comprising: receiving information indicating an uplink transmission grant for the WTRU and a priority associated with the uplink transmission grant; determining that data associated with a first logical channel is available for transmission; determining that the priority associated with the uplink transmission grant matches a priority associated with the first logical channel; determining, based on the priority associated with the uplink transmission grant matching priority associated with the first logical channel, the data associated with the first logical channel is to be transmitted using the uplink transmission grant; and transmitting the data associated with the first logical channel using the uplink transmission grant. ### Claim 11 (depends on 10) The method of claim 10, further comprising receiving configuration information that indicates the priority associated with the first logical channel. ### Claim 12 (depends on 10) The method of claim 10, wherein the determination that the data associated with the first logical channel is to be transmitted using the uplink transmission grant is based further on a determination that a subcarrier spacing associated with the uplink transmission grant is among one or more subcarrier spacings associated with the first logical channel. ### Claim 13 (depends on 10) The method of claim 10, wherein the determination that the data associated with the first logical channel is to be transmitted using the uplink transmission grant is based further on a transmission timing parameter associated with the uplink transmission grant. ### Claim 14 (depends on 10) The method of claim 10, further comprising determining that data associated with a second logical channel is available for transmission and determining, based on at least the priority associated with the uplink transmission grant and a priority associated with the second logical channel, that the data associated with the second logical channel is not to be transmitted using the uplink transmission grant. ### Claim 15 (depends on 14) The method of claim 14, further comprising transmitting a scheduling request (SR) to a base station in response to determining that the data associated with the second logical channel is not to be transmitted using the uplink transmission grant. ### Claim 16 (depends on 15) The method of claim 15, wherein the SR is transmitted to the base station using one or more SR resources configured for the second logical channel. ### Claim 17 (depends on 16) The method of claim 16, further comprising receiving configuration information that indicates the one or more SR resources configured for the second logical channel. ### Claim 18 (depends on 10) The method of claim 10, wherein the information that indicates the uplink transmission grant and the priority associated with the uplink transmission grant is received via a downlink control channel.
