Threshold-based and power-efficient scheduling request procedure

A method executed by a base station, comprising:

• transmitting, to a user equipment, configuration information to configure a timer for a logical channel of the user equipment;
• and
• receiving a scheduling request transmitted from the user equipment requesting uplink resources,
• wherein transmission of the scheduling request from the user equipment to the base station is triggered by the user equipment:
• determining that a first trigger condition is fulfilled for the logical channel based on data becoming available in a transmission buffer of the user equipment;
• starting the timer when the first trigger condition is fulfilled to delay transmission of the scheduling request;
• and
• determining that a second trigger condition is fulfilled for the logical channel based on expiration of the timer.

A method executed by a user equipment, the method comprising:

• receiving, from a base station, configuration information to configure a timer for a logical channel of the user equipment;
• determining a buffer status report is triggered based on data for the logical channel becoming available in a transmission buffer of the user equipment;
• starting the timer based on the buffer status report being triggered to delay transmission of a scheduling request;
• determining a trigger condition is fulfilled based on expiration of the timer;
• and
• transmitting the scheduling request based on determining that the trigger condition is fulfilled.

A user equipment comprising:

• a transmission buffer to buffer uplink data to be transmitted to a network;
• processing circuitry coupled with the transmission buffer, the processing circuitry to:
• receive, from the network, configuration information to configure a timer for a logical channel of the user equipment;
• determining a buffer status report is triggered based on data for the logical channel becoming available in the transmission buffer of the user equipment;
• starting a timer based on the buffer status report being triggered to delay transmission of a scheduling request;
• determining the trigger condition is fulfilled based on expiration of the timer;
• and
• transmitting the scheduling request based on determining that the trigger condition is fulfilled.

One or more non-transitory, computer-readable media having instructions that, when executed by one or more processors, cause a user equipment to:

• receive, from a base station, configuration information to configure a timer for a logical channel of the user equipment;
• determine a buffer status report is triggered based on data for the logical channel becoming available in a transmission buffer of the user equipment;
• start the timer based on the buffer status report being triggered to delay transmission of a scheduling request;
• determine a trigger condition is fulfilled based on expiration of the timer;
• and
• transmit the scheduling request based on determining that the trigger condition is fulfilled.
