Radio measurement procedure in wireless communication system

A radio measurement method for measuring station statistics in a wireless communication network, the method comprising:

• receiving a triggered station statistics measurements request message from a requesting 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 the requested QoS statistics group, and the triggered reporting field for QoS station counters being used to specify trigger conditions and QoS statistics thresholds;
• measuring requested QoS station statistics;
• and
• transmitting a QoS station statistics measurements report message to the requesting 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.

A station for supporting a radio measurement method for measuring station statistics in a wireless communication network, the station comprising:

• a processor configured to generate and process frames;
• and
• a transceiver operably connected to the processor and configured to transmit and receive the frames for the processor,
• wherein the transceiver is configured to:
• transmit a request frame to a requested station for triggered quality of service (QoS) station statistics measurements, the request frame generated by the processor and including a group identity field and a triggered reporting field for QoS station counters, the group identity field indicating a requested QoS statistics group, and the triggered reporting field being used to specify trigger conditions;
• and
• receive 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.
