US 11,696,280 B2 · On-demand scheduling request design

Abstract

An on-demand scheduling request (SR) design is disclosed. Such an on-demand or triggered SR operation provides pre-configuration of user equipments (UEs) with triggered SR resources. Base stations may also configure UEs to monitor for a trigger signal within a bit field of control signaling from the base station. Upon detecting the trigger signal within such bit field, the UEs may use the triggered SR resources for transmitting triggered SR requests. Such use of the triggered SR resources may be in response to UEs detected cancelation of other periodic configured SR resources.

Claims30

Dependent claims

A method of wireless communication performed by a user equipment (UE), comprising:

receiving, from a serving base station, a configuration message that indicates a bit field within a control message;
monitoring for the bit field in the control message to detect a value of at least one bit of the bit field that indicates a trigger signal to trigger transmission of a scheduling request (SR);
and
transmitting using a transmission resource configured based on the configuration message, the SR in response to detection of the trigger signal.

1 more element

An apparatus configured for wireless communication, the apparatus comprising:

at least one processor;
and
a memory coupled to the at least one processor,
wherein the at least one processor is configured to:
receive, from a serving base station, a configuration message that indicates a bit field within a control message;
monitor for the bit field in the control message to detect a value of at least one bit of the bit field that indicates a trigger signal to trigger transmission of a scheduling request (SR);
and
transmit using a transmission resource configured based on the configuration message, the SR in response to detection of the trigger signal.
