Abstract

A terminal apparatus includes: a measurement unit configured to measure at least one of a latency when a wireless signal is transmitted to a access point and a jitter of the wireless signal; a data processing unit configured to generate information including a result of the measurement; and a wireless communication processing unit configured to transmit the information to the access point.

Claims (34)

1 . A terminal apparatus comprising:

a processor configured to:

measure a latency when a wireless signal is transmitted to an access point and a jitter of the wireless signal; and

generate information including a result of the measurement; and

a wireless signal processing circuit configured to transmit the information to the access point,

wherein the processor measures the latency and the jitter for each item of traffic identification information added to data included in the wireless signal.

2 . The terminal apparatus according to claim 1 , wherein the information includes information regarding an attribute of the terminal apparatus.

3 . The terminal apparatus according to claim 1 , wherein the processor measures the latency from a period of time from when the wireless signal processing circuit transmits the wireless signal to when an acknowledge from the access point is received.

4 . The terminal apparatus according to claim 1 , wherein the processor measures the latency from a period of time from when a MAC frame including data of the wireless signal is input to an end of a transmission queue of the wireless signal processing circuit to when the MAC frame arrives at a head of the transmission queue.

5 . The terminal apparatus according to claim 1 , wherein the processor measures the latency from a period of time from when a MAC frame including data of the wireless signal reaches a head of a transmission queue of the wireless signal processing circuit to when the wireless signal processing circuit transmits the wireless signal.

6 . The terminal apparatus according to claim 1 , wherein the processor measures the latency from a period of time from when a retransmission request of the wireless signal is received from the access point to when the wireless signal processing circuit retransmits the wireless signal.

7 . The terminal apparatus according to claim 1 , wherein the processor further measures interference when the wireless signal is transmitted, and

generates information including a result of the measurement of the interference.

8 . A terminal apparatus comprising:

a processor configured to:

measure a latency when a wireless signal is transmitted to an access point and a jitter of the wireless signal; and

generate information including a result of the measurement; and

a wireless signal processing circuit configured to transmit the information to the access point,

wherein the wireless signal processing circuit controls transmission of the wireless signal in accordance with an access category of the wireless signal classified in accordance with data included in the wireless signal, and

the processor measures the latency and the jitter for each access category.

9 . A communication method comprising:

by a terminal apparatus, measuring a latency when a wireless signal is transmitted to an access point and a jitter of the wireless signal, wherein the latency and the jitter for each item of traffic identification information added to data included in the wireless signal are measured;

by the terminal apparatus, generating information including a result of the measurement; and

by the terminal apparatus, transmitting the information to the access point.

10 . A non-transitory storage medium storing a communication program for causing a processor of a terminal apparatus to perform:

measuring a latency when a wireless signal is transmitted to an access point and a jitter of the wireless signal, wherein the latency and the jitter for each item of traffic identification information added to data included in the wireless signal are measured;

generating information including a result of the measurement; and

transmitting the information to the access point.

11 . A communication method comprising:

measuring a latency when a wireless signal is transmitted to an access point and a jitter of the wireless signal;

generating information including a result of the measurement; and

transmitting the information to the access point,

wherein the wireless signal is transmitted in accordance with an access category of the wireless signal classified in accordance with data included in the wireless signal, and the latency and the jitter are measured for each access category.

12 . A non-transitory storage medium storing a communication program for causing a processor of a terminal apparatus to perform the communication method of claim 11 .
