US 10,313,913 B2 · Overload control and supervision for wireless devices

Abstract

Methods, systems, and/or devices are described for are provided for transmission overload control and/or supervision of wireless devices. Tools and techniques may be provided for resolving issues associated with numerous wireless devices connected to a base station. For example, a transmission cycle for an uplink channel may be identified where the transmission cycle is discontinuous. Scheduling request and or Random Access Channel messages may be transmitted from a wireless device based on the discontinuous transmission cycle. Tools and techniques are also provided that may involve supervision of numerous wireless devices. Supervision may, for example, involve keep-alive messages transmitted in accordance with a timer. The supervision may be based on determination of, and transmissions related to, a list or lists of connected wireless devices. In some cases, the wireless devices may be delay tolerant. The wireless devices may include UEs that may have long sleep cycles and/or machine-type communications (MTC) devices.

Dependent claims

A method for wireless communication comprising:

receiving a discontinuous transmission (DTX) cycle indication from a base station;
identifying, by a wireless device in a connected state, a first transmission cycle of a DTX cycle for an uplink channel based at least in part on the DTX cycle indication, wherein the wireless device is part of a first set of wireless devices utilizing the first transmission cycle, and wherein a second set of wireless devices utilizing a second transmission cycle that is staggered from the first transmission cycle refrain from transmission during the first transmission cycle;
identifying a first off cycle of the DTX cycle with respect to the first transmission cycle for the uplink channel, wherein the wireless device refrains from transmitting during the first off cycle;
and
transmitting, by the wireless device, a scheduling request or a random access channel message during the first transmission cycle of the DTX cycle, the first transmission cycle and second transmission cycle comprising staggered times for scheduling request or random access channel message transmissions.
