Abstract
The present disclosure discloses a wireless communication system having reliable network medium access mechanism that includes a station apparatus and an access point apparatus. The station apparatus is arranged to transmit a stub signal for signaling a data transmission to be performed, wherein the stub signal does not include information of the data transmission. The access point apparatus is arranged to receive the stub signal and transmit a transmission polling signal for signaling a permitted time period so as to permit the station apparatus to perform the data transmission in the permitted time period.
Claims18
An access point apparatus, comprising:
- a communication circuit;
- and
- a processing circuit coupled to the communication circuit to perform signal transmission and signal receiving therethrough, and the processing circuit arranged to:
- receive a stub signal from a station apparatus for signaling a data transmission to be performed thereof, wherein the stub signal does not comprise information of the data transmission, and the information of the data transmission at least comprises addresses of the station apparatus and the access point apparatus;
- transmit a transmission polling signal for signaling a permitted time period so as to permit the station apparatus to perform the data transmission in the permitted time period;
- receive a response signal from the station apparatus in the permitted time period, wherein the response signal comprises requested information that requests to perform a subsequent data transmission;
- and
- transmit a subsequent transmission polling signal, that identifies the station apparatus based on the response signal, for signaling a subsequent permitted time period according to the requested information so as to permit the station apparatus to perform the subsequent data transmission.
A station apparatus, comprising:
- a communication circuit;
- and
- a processing circuit coupled to the communication circuit to perform signal transmission and signal receiving therethrough, and the processing circuit arranged to:
- receive an invitation polling signal signaling a plurality of time slots and transmit a stub signal for signaling a data transmission to be performed to an access point apparatus, wherein the stub signal does not comprise information of the data transmission, and the information of the data transmission at least comprises addresses of the station apparatus and the access point apparatus;
- transmit a selection signal corresponding to a desired time slot combination that comprises one or more than one of the time slots;
- receive a transmission polling signal for signaling a permitted time period that identifies the station apparatus to be a selected station apparatus from the access point apparatus;
- and
- perform the data transmission in the permitted time period.
A wireless communication system, comprising:
- a station apparatus arranged to receive an invitation polling signal signaling a plurality of time slots, transmit a stub signal for signaling a data transmission to be performed and transmit a selection signal corresponding to a desired time slot combination that comprises one or more than one of the time slots, wherein the stub signal does not comprise information of the data transmission, and the information of the data transmission at least comprises addresses of the station apparatus and the access point apparatus;
- and
- an access point apparatus arranged to transmit the invitation polling signal to the station apparatus, receive the stub signal and the selection signal from the station apparatus and transmit a transmission polling signal to the station apparatus for signaling a permitted time period that identifies the station apparatus to be a selected station apparatus, so as to permit the station apparatus to perform the data transmission in the permitted time period.
