Methods and systems for managing operation of a deployment of data processing systems are disclosed. The operation may be managed by determining a synchronicity classification of data that is to be transmitted between the data processing systems, and performing the transmission based on the synchronicity classification. The data may be classified as synchronous and / or asynchronous.

The use of a TWT service period allows other devices to use the wireless medium outside the TWT service period.

A broadcast framework for providing an audio stream to two or more receiver devices includes user equipment (UE) broadcasting packets of the audio stream on isochronous channels based on a broadcast channel mask. Concurrently with broadcasting these packets, the UE listens for advertisement packets each indicating a corresponding receiver channel mask and corresponding link quality data from the receiver devices receiving the audio stream. Using the link quality data from the advertisement packets, the UE weighs the receiver channel masks from the advertisement packets and modifies the broadcast channel mask based on the weighted receiver channel masks. The UE then broadcasts packets of the audio stream based on the modified broadcast channel mask.

Each TA comprises intra-frequency cells only. By using the WBO, the user device may reduce its power consumption by avoiding switching from its sleep state to its active state when doing cell reselections in the TA.
