Abstract

Techniques and apparatus for early termination of decoding of communication channels for power saving in narrowband devices are provided. One technique includes monitoring for one or more first repetitions of at least one communication channel from a base station. The device determines, based on the monitoring, whether to refrain from monitoring for one or more second repetitions of the at least one communication channel. The device enters a low power mode if the determination is to refrain from monitoring for the one or more second repetitions of the at least one communication channel.

Claims30

Dependent claims

A method for wireless communications by a user equipment (UE), comprising:

determining a first number of repetitions of at least one control channel communication from a base station to monitor based at least in part on a channel quality between the UE and the base station, wherein the first number of repetitions is less than a second number of repetitions of the at least one control channel communication configured for the UE;
monitoring for the first number of repetitions of the at least one control channel communication from the base station;
after monitoring for the first number of repetitions of the at least one control channel communication, refraining from monitoring for one or more additional repetitions of the at least one control channel communication;
and
entering a low power mode during the one or more additional repetitions of the at least one control channel communication.

2 more elements

An apparatus for wireless communications, comprising:

at least one processor;
memory coupled to the at least one processor, the memory comprising instructions executable by the at least one processor to cause the apparatus to:
determine a first number of repetitions of at least one control channel communication from a base station to monitor based at least in part on a channel quality between the apparatus and the base station, wherein the first number of repetitions is less than a second number of repetitions of the at least one control channel communication configured for the apparatus;
monitor for the first number of repetitions of the at least one control channel communication from the base station;
after monitoring for the first number of repetitions of the at least one control channel communication, refrain from monitoring for one or more additional repetitions of the at least one control channel communication;
and
enter a low power mode during the one or more additional repetitions of the at least one control channel communication.

4 more elements

A non-transitory computer-readable medium having computer executable code stored thereon for performing a method for wireless communications by an apparatus, the method comprising:

determining a first number of repetitions of at least one control channel communication from a base station to monitor based at least in part on a channel quality between the apparatus and the base station, wherein the first number of repetitions is less than a second number of repetitions of the at least one control channel communication configured for the apparatus;
monitoring for the first number of repetitions of the at least one control channel communication from the base station;
after monitoring for the first number of repetitions of the at least one control channel communication, refraining from monitoring for one or more additional repetitions of the at least one control channel communication;
and
entering a low power mode during the one or more additional repetitions of the at least one control channel communication.
