Abstract: In dense Wireless Local Area Network (WLAN) deployments, Access Points (APs) in other Extended Service Sets (ESSs) can be hidden (a first AP does not receive signals from a third AP). However, these APs in other ESSs can still interfere with communications between the third AP and the devices communicating with the first AP. To improve service to that device in that situation, the first AP needs information about the third AP in the first AP's decision making processes. In these situations, a second AP, in contact with the third AP, can share information about the third AP with the first AP so that the first AP can avoid colliding with the third AP.

Abstract: Various embodiments disclosed herein provide for a codeblock segmentation configuration system. A base station can configure the segmentation rate or segment size, which can control the number of codeblock segments a transport block is segmented into, based on the transmission reliability and predicted interference to a mobile device. An increased number of segments can improve throughput and efficiency when interference is low and signal to noise ratios are high, but can increase latency when interference is high and signal to noise is low. The base station can determine or predict transmission reliability based on the speed of mobile devices, the location and/or distance to the mobile device, as well as the long term signal to noise ratios.

Abstract: Techniques for processing application data are described. The techniques include transmitting packets of application data to a data management server. The data management server maintains rules that dictate where the packets go as well as what actions are taken in response to the packets.
