Scheduling request in a wireless device and wireless network

A wireless device comprising:

• a memory comprising computer-executable instructions;
• and
• a processor configured to execute the computer-executable instructions and cause the wireless device to:
• receive a message from a base station, the message indicating a first scheduling request (SR) resource associated with a first logical channel and a second SR resource associated with a second logical channel;
• trigger an SR in response to an uplink resource not being available for transmission of a buffer status report (BSR), wherein the BSR is in response to uplink data becoming available for one of the first logical channel and the second logical channel;
• select one of the first SR resource and the second SR resource based on which one of the first logical channel and the second logical channel has uplink data becoming available;
• transmit the SR to the base station via the selected one of the first SR resource and the second SR resource;
• and
• receive an uplink grant for transmission of a transport block,
• wherein at least one of the first logical channel and the second logical channel corresponds to a transmission duration for transmission of the transport block in a transmission time interval.

A method comprising:

• transmitting a message to a user equipment (UE), the message indicating a first scheduling request (SR) resource associated with a first logical channel and a second SR resource associated with a second logical channel;
• receiving an SR from the UE via a SR resource, wherein the SR resource is one of the first SR resource and the second SR resource;
• determining an uplink grant for transmission of a transport block based on which one of the first logical channel and the second logical channel corresponds to the SR resource;
• and
• transmitting the uplink grant to the UE,
• wherein at least one of the first logical channel and the second logical channel corresponds to a transmission duration for transmission of the transport block in a transmission time interval.

A base station comprising:

• a memory comprising computer-executable instructions;
• and
• a processor configured to execute the computer-executable instructions and cause the base station to:
• transmit a message to a user equipment (UE), the message indicating a first scheduling request (SR) resource associated with a first logical channel and a second SR resource associated with a second logical channel;
• receive an SR from the UE via a SR resource, wherein the SR resource is one of the first SR resource and the second SR resource;
• determine an uplink grant for transmission of a transport block based on which one of the first logical channel and the second logical channel corresponds to the SR resource;
• and
• transmit the uplink grant to the UE,
• wherein at least one of the first logical channel and the second logical channel corresponds to a transmission duration for transmission of the transport block in a transmission time interval.
