Patent ID: 8284742

Claim:
A radio measurement method for measuring station statistics in a wireless communication network, the method comprising: transmitting a triggered station statistics measurements request message to a requested station, the triggered station statistics measurements request message including a group identity field and a triggered reporting field for quality of service (QoS) station counters, the group identity field indicating a requested QoS statistics group, and the triggered reporting field for QoS station counters being used to specify trigger conditions; and receiving a QoS station statistics measurements report message from the requested station when at least one of the trigger conditions occurs, wherein: the triggered reporting field comprises: a QoS station counters trigger condition subfield specifying reporting triggers and including one or more bit-fields for each one of the reporting triggers, and one or more QoS threshold subfields for specifying values representing a number of data units used as QoS threshold values for each of the reporting triggers; the one or more QoS threshold subfields includes at least a QoS failed threshold subfield, a QoS retry threshold subfield, a QoS multiple retry threshold subfield, a QoS frame duplicate threshold subfield, a QoS request to send (RTS) failure threshold subfield, a QoS acknowledgement (ACK) failure threshold subfield or a QoS discarded threshold subfield; and each of the one or more QoS threshold subfields is present when a particular bit field for each of the reporting triggers in the QoS station counters trigger condition subfield is set to 1.
