US 2026/0101326 A1 · PERFORMANCE IMPROVEMENT AT SLEEP EXITS FOR FREQUENCY SPUR CHANNELS

Abstract

Methods, systems, and devices for wireless communications are described. Generally, the described techniques may enable a user equipment (UE) to disable a sleep mode or awake from sleep earlier for channels or bandwidths that have a frequency spur compared to channels or bandwidths without a frequency spur. Awaking from sleep earlier may enable a band stop filter of the UE to receive more samples to suppress the frequency spur and reduce sensitivity degradation of the UE for decoding control messages. The UE may disable the sleep mode or wake earlier based on a signal-to-noise ratio (SNR) of received signal, a magnitude of the frequency spur, a coding rate of the control message, a bandwidth of the control message, or any combination thereof.

Dependent claims

A user equipment (UE), comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
receive one or more control messages indicating, based at least in part on a presence or absence of a grant in the one or more control messages, a first sleep configuration for a channel associated with the UE and indicating a first sleep duration associated with the first sleep configuration for the channel;
select a second sleep configuration for the channel based at least in part on a presence of a frequency spur in one or more frequencies associated with the channel, the second sleep configuration corresponding to a second sleep duration shorter than the first sleep duration;
and
monitor, in an awake state, the channel after the second sleep duration based at least in part on the second sleep configuration.

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

receiving one or more control messages indicating, based at least in part on a presence or absence of a grant in the one or more control messages, a first sleep configuration for a channel associated with the UE and indicating a first sleep duration associated with the first sleep configuration for the channel;
selecting a second sleep configuration for the channel based at least in part on a presence of a frequency spur in one or more frequencies associated with the channel, the second sleep configuration corresponding to a second sleep duration shorter than the first sleep duration;
and
monitoring, in an awake state, the channel after the second sleep duration based at least in part on the second sleep configuration.

1 more element

A non-transitory computer-readable medium storing code for wireless communications, the code comprising instructions executable by one or more processors to:

receive one or more control messages indicating, based at least in part on a presence or absence of a grant in the one or more control messages, a first sleep configuration for a channel associated with a user equipment (UE) and indicating a first sleep duration associated with the first sleep configuration for the channel;
select a second sleep configuration for the channel based at least in part on a presence of a frequency spur in one or more frequencies associated with the channel, the second sleep configuration corresponding to a second sleep duration shorter than the first sleep duration;
and
monitor, in an awake state, the channel after the second sleep duration based at least in part on the second sleep configuration.
