Mechanisms of status reporting and protected period setting for coordinated transmission in multiple AP system
Mechanisms of CCA status reporting and NAV distribution for coordinated transmissions in a multi-AP WLAN. A coordinator AP may broadcast a RTS frame to a set of coordinated APs, which allow the coordinated APs with a CCA clear status to set a protected period in a CST frame to silence the associated non-AP STAs. The coordinator AP also polls the coordinated APs to have them individually report their CCA statuses as well as additional information used for transmission coordination. In some embodiments, a status report from a coordinated AP may integrate the protected period setting and the CCA clean status indication, and therefore the coordinator AP just needs to poll for such a report without using RTS/CTS exchange. A coordinated AP may set a protected period to end at the complete transmission of a coordination frame. The coordination frame may specify the remaining TXOP duration information. |

Systems and methods for retrieving segmented media guidance data
Systems and methods are presented for reducing network traffic when retrieving media guidance data. For example, a media guidance application receives a first user selection to display a group of media asset identifiers (e.g., video-on-demand listings) and retrieves detailed information from a remote server relating to the media asset identifiers to display to a user. The media guidance application then may receive a user selection to display a second group of media asset identifiers (e.g., purchased media assets). If any of the media asset identifiers are common to both groups, then the media guidance application already obtained the detailed information and the detailed information does not need to be retransmitted in order to be displayed. Thus, the media guidance application only retrieves detailed information for media asset identifiers unique to the second group of media asset identifiers (e.g., they are only on the purchased media asset list). |
