  1. CVS Request Signaling Authors: Qualcomm Incorporated

  2. Abstract CVS in 802.11af Draft 1.0 is a unicast frame that is transmitted from the enabling AP/STA. Several conditions may cause an STA to miss the CVS such as degraded link quality, or wrong MCS used by the enabling STA. To address this scenario, it is useful to have a message for a STA to request a CVS from its enabling AP/STA. This message is sent by an STA that has not recieved the CVS , prior to the CVS interval expiring, to trigger a CVS from the enabling STA. Qualcomm Incorporated

  3. Comment ID • This contribution addresses CID 2 • Sections that are affected: • 6.3 MLME SAP Interface, add 6.3.af7 • 8.5.8.1, add 8.5.8.af8 • 10.af2.3: Add one paragraph • Text in: 02-11-0263-01-00af-normative-text-for-cvs-report.doc Qualcomm Incorporated

  5. CVS Request IE. • STA sends a CVS request Action frame • The Category field is set to the value for public  • The Action field is set to indicate a CVSR frame •  A MIB dot11CVSResponseTimeout is defined • This MIB is the time limit for the CVS to be sent from the enabling STA after receiving CVS request. • Once the enabling STA receives the CVS request, AP responds with a secure unicast CVS frame with in dot11CVSResponseTimeout .
