Take the vector (NAV). Address-1 block 325 or 365 may include the destination address of the frame. The Address-2 field 330 may include the address of the transmitting station and the FCS field 345 or 380 may include a Cyclic Redundancy Check (CRC) value for the frame. 12 1320276 Although the field of the present invention is not limited thereto, the xDuration block 335 of the RTSM frame 310 can include a value consisting of the length of the CTSM frame 35, at least twice the length of the SIFS, and the length of the data series. In some embodiments of the invention, for example, STA 120, STA 150, and AP 110 may use the value of 5 x Duratlon clamp 335 to update the NAV as desired. Fields 340 and 370 may include a plurality of transmitters and/or receivers of the system 230 that may be utilized by the encoding of the system 230. For example, space multiplex and diversity. Turning to Fig. 4, a communication protocol 10 parental negotiation, in accordance with an illustrative embodiment of the present invention, is used for SIS0 and/or MISO mode of operation to a mode of operation to switch a time map display of a wireless communication device. Although the field of the invention is not limited to this, 'time maps 41 〇, 42 〇, 430 and 440 show the time flow of the NAV (eg, time map 430, 440), from a station and/or Α ρ (eg, time chart 42 〇) One request and one sign (as shown in time chart 41〇). For example, Αρ 11〇 can initiate a 15 request to use the determined number of receivers of the ΜΙΜΟ system 230 of the station 120 of the wireless communication system. In addition, time maps 45A, 455 may be displayed in relation to other types of stations and stations, such as the conventional station STA 130. Although the field of the invention is not limited thereto, the WLAN may include two or more types. Type platform and / or AP. For example, the first type of platform and the eight? Can be HT platform. The HT type platform and/or AP may include a ΜΙΜΟ system. The second type of station and Ap may be an existing conventional station and AP. According to an exemplary embodiment of the present invention, the AP 110 operates in the MISO operating mode, and the RTSM frame (such as the RTSM 310) may include a It is required to use, for example, a STA 120 receiver. In accordance with this example, the requirement to use the desired number of receivers can be provided by the interception of RTSM frame 310. In response, the STA 12 can sign the receiver of the RTSM frame 310 by transmitting the CTSM frame 350 to ( 11〇 (within the range of 511^5 after the completion of the transmission of the frame).

Although the field of the invention is not limited thereto, in some embodiments, the length block 360 of the CTSM frame 10 350 transmitted by the STA 120 can be subtracted from the length of the CTSM frame 350 and the SIFS time by the RTSM. The xDuration field of frame 310 is calculated. Although the field of the invention is not limited thereto, STA 150 may also receive RTSM frame 310 and initiate, for example, a length consisting of two SIFS times and an overlap time including the beginning of the sequence of data frames as shown in time map 430. 15 NAV In some embodiments of the invention, NAV1 can be used to block other stations and/or APs on the WLAN. Further, the legacy station 13 can receive the RTSM frame 310 and can use the length block 320 to activate the NAV 3. Thus, the STA 130 can be blocked on the length of the NAV 3 when desired. Although the field of the invention is not limited in this regard, AP 110 can receive 2〇CTSM frame 350 and can use the value provided by length field 360 of CTSM frame 350 as shown in time diagram 440 when desired. The length starts NAV2. In addition, in accordance with some embodiments of the present invention, STA 150 and STA 130 may initiate NAV2 and NAV4 using the length field 360 of CTSM frame 350 as indicated by time map 440 and time map 450, respectively, as desired. 14 Although the field of the present invention is not limited to this, after the RTS/CTS handshake coordination and the blocking of other station transmissions are completed, the AP 110 may start transmitting the data sequence SIFS time after the CTSM frame 350 transmission is completed. However, in some embodiments of the invention, at least one WLAN station and/or UI will not receive the CTSM frame 350. In these embodiments, the initiator that switches the station's job mode to the job mode does not send a data sequence. In these embodiments, the stations and/or ports will not initiate NAV to block transmissions. Although the field of the invention is not limited to this, only some WLAN stations and/or APs can receive the sign-off message. For example, ap 110 can receive CTSM frame 350 and STA 150 does not receive CTSM frame 350. In these embodiments of the present invention, the STA 150 may use the xDuration field 335 of the RTSM frame 310 (shown by the dashed line in time chart 430) to augment the data sequence transmission when the received data sequence is transmitted. However, an existing conventional station (e.g., STA 130) may augment the NAV 3 at least at the end of the first frame of the data frame as desired (the dotted line in time chart 455 is displayed). Returning to Fig. 5, a flow chart of a method of employing a chirp mode of a wireless communication device in accordance with an illustrative embodiment of the present invention is shown. Although the field of the invention is not limited thereto, a wireless communication system (such as a WLAN) wireless communication device (station and/or AP) may require a recipient to alternate its current mode of operation (eg, SISO or MISO). MIM ◦ job mode (block 510). In addition, the wireless communication device may, for example, not access the wireless shared medium 160 for a predetermined period of time by activating a NAV during the desired blockade (block 520). 1320276 While the field of the invention is not limited in this regard, the recipient may transmit a wireless communication device (e.g., an initiator) that signs the request. In the second embodiment of the present invention, if the money is received by the wireless communication device (blocked), the wireless communication device can extend the NAV blocking time according to the information received by the receipt message (block 540). . - Although the field of the invention is not limited thereto, in some embodiments of the invention 'if the sign is not received by the radio track device (block 53A), the wireless device can be, for example, based on MJM The data sequence length is extended by NAV to extend the blockade time (block 56〇). While the invention has been described and illustrated herein, many modifications, substitutions, changes and equivalents will now occur to those skilled in the art. Therefore, it is to be understood that the scope of the appended claims is intended to cover all such modifications and changes as fall within the true spirit of the invention.
