Currently, the IEEE 802.1 In extension has been proposed to achieve higher throughput (HT). In the IEEE 802.1 In proposal, a new motion frame is introduced for providing a transmission mode and a channel feedback, wherein the transmission mode feedback enables a receiving station to be notified that it is in the current channel condition. a transmission station of a preferred mode, and the selection of the special mode is determined by the receiving station, however, the transmission station may or may not use the special mode, everything depends on its capabilities, and A receiving station can also refuse to provide a better mode. In addition, the channel information feedback system provides a mechanism for a transmitting station to learn the precise channel seen at the receiving station, and the information can be used as a A part of the calibration, which is used in systems with channel reciprocity, or used directly as channel feedback. A receiving station may provide a complete channel evaluation, or A null response. Examples of such IEEE 802.1 In motion frames are Mode Request, Mode Response, multiple-input multiple-output (Channel), and channel response. (ΜΙΜΟ Channel Response) and other frames. The management frame (including the action frame) can broadcast, or multicast 7 M296548 (multicast) to multiple responders (for example, via a beacon frame), or, alternatively, can be unicast (unicast) to a special (single) responder (eg, ADDBA request, ADDBA response, mode request, mode response, channel request, and channel response), where a management, or action frame is singled out When broadcasting to a special responder, the IEEE 802.11 standard will require the responder to acknowledge receipt of such a frame by sending an ACK packet. On the other hand, if the management or action frame is broadcast, Or multicasting is a multiple response to the 夯 守 'The IEEE 802 · 11 standard does not require such responders to acknowledge receipt of such a frame. The diagram is a sequence of a conventional program for managing between the ^ ^ αβ 1U4 and the exchange of motion frames, and transmitting the pattern. The initiator 102 will access wireless media that require a delay corresponding to the contention (c〇ntenti〇n) or access delay of the 802.11 standard, and will send a motion frame.

Therefore, there is a need for a mechanism for performing such management or exchange of action frames in a very short period of time. [New Content] This creation is related to a device for improving the management of a Wlan and controlling the exchange reactivity of the 9 M296548 frame. An initiator sends a frame (action, management, control, or data frame) to a responder, and after receiving the frame correctly, the responder sends a response frame to the initiator. Instead of directly transmitting an acknowledgment (ACK) packet, and preferably, the responder accesses the wireless medium to transmit the short inter-frame spacing (SIFS). Respond to the frame. By this planning, a long delay system that must compete for the non-φ line media in order to transmit the response frame can be avoided, and therefore the reactivity and timeliness of the feedback mechanism can be significantly enhanced, and wherein The response frame can be piggybacked on another packet or combined with another packet.

nouns' "initiator" and "responder" include, but are not limited to, a user equipment (like "equipment, UE"), a wireless transmission/reception unit (wireless transmit /receive unit 5 WTRU ), a mobile station, a fixed, mobile subscriber unit, a pager, a Node B (B-B), a base station, a site controller, an access point, or Any other type of device capable of operating in a wireless environment. The features of the present invention may be incorporated into an integrated circuit (IC) or constructed in a circuit that includes a plurality of interconnecting members. 2 is based on one of the present works for the action between the initiator 2〇2 (also known as the originator) and a responder 204 (also known as the recipient). A signal transmission pattern of the block exchange program 2〇〇10 M296548, wherein the initiator 202 is configured to grasp a transmission opportunity (TXOP) and combine the data unit by a physical layer protocol (aggregate Physical layer protocol data units (A-PPDUs), or a communication entity that transmits a first frame in conjunction with the frame exchange order of the control frame, and the responder 204 is a combination of A-PPDUs and a combination. The frame exchange order of the control frame is returned to the communication entity of the initiator 202. The initiator 202 φ sends an action frame (usually a request frame, such as a mode request frame) to a responder. 204 (step 212), and after correctly receiving the action frame, instead of directly transmitting an ACK packet, the responder 204 sends a response action frame (eg, a mode response frame) (step 214). After that, this creation will be described with reference to the motion frame. However, it should be noted that this creation is also applicable to any type of frame, for example, management frame, control. a frame, a data frame, or the like, and the request frame and the response frame can be different types of frames. Preferably, the responder 204 accesses the wireless medium to Corresponding to one The SIFS sends the response action frame for a period of time, and then the initiator 202 sends an ACK frame after a short delay, preferably corresponding to the SIFS (step 216). The long delay that must compete for the wireless medium when connected to step 116 in Figure 1 is avoided, and therefore the reactivity and timeliness of the feedback mechanism is significantly enhanced. Alternatively, alternatively, the response action frame in step 214 may also be dated on an ACK, a packet, another dry or a data packet, or may be with: = another frame - The ACK packet sent by the management or control frame, or a data packet combined with CK = packet plus "negative, or combined, the response (9) start action frame 2: request frame) will not be Eliminate and send with another frame. The signaling mechanism of this creation can be performed by both the =:= device 202 and the responder 2〇4: In the situation, the extra block will be included in the r (four) _, - control frame, - data message::, 丄Z to tie the better signal transmission mechanism, the starter, can send 1 request Frame (for example, ^ frame, - MIM ◦ channel request frame... MCS request, MCS request, MRQ) frame, one channel status information (- enemy mfonnat Cong, CSI) request frame, - calibration start (eaiibfati〇 n jia) frame, a # transmit antenna select vocal request • 匡 a - her selectlon sounding Request frame ), or a training request 'TRQ frame, or the like, and it is set in the request frame to indicate how the responder 2〇4 is expected to respond The new position of the request §fl box. The new fields include, but are not limited to, an ACK policy field, a request identification number field, a response time policy block, and a combined policy block. At least one of the ACK policy fields, and the ACK policy field indicates whether the responder 204 needs to send an ACK packet. 12 M296548 The request identification number intercepting system includes a request identification number, and a response frame is A similar request identification number field will be used, and the value will correspond to the request identification number in the request frame, or alternatively, if the response frame is sent as much as possible The request identification number block in the response frame can be set to a special value, which will be explained in detail later. The response time delay policy block will indicate the response. Whether or not Φ4 is expected to immediately send a response frame to the initiator 202 (i.e., SIFS), or to be within a certain time delay range that is longer than the short delay, or At the point in time selected by the responder 204 (i.e., unsolicited). The combined policy field indicates whether the responder 204 is expected to send the piggyback on another packet, Or a response frame combined with other packets, such as an ACK packet, a management or control packet, a data packet, or other type of packet, and multiple management frames can be combined in one In the package. Here, when an MMPDU is transmitted independently (ie, 'not part of a combination), a simple ACK is used, and when one or more MMPDUs are transmitted as part of a combination, then A block ACK (BA) can be used. When the ACK policy is selected to include an ACK that responds to the response frame, the next plan can be implemented. The MMPDUs will utilize a separate counter that is not unique to each responder and will be assigned a sequence number (sequence numbers, 13 M296548 SNs) by the 5 start state 202, and will also be used for broadcast/multiple Point broadcast frames, and for non-QoS data subtype frames (non-Q〇s_data subtype frames). According to the present creation, the management frame is sorted by using a pair of unique SN counters each uniquely unique, or alternatively, the management frame can be sorted by the same SN counter. Just like the data combined with the management frame. Alternatively, the same IEEE 802.lle method for assigning SNs to the management frame will be used, and the responder 204 will not rearrange the management frames because of the reception at the reception. The interval between the SNs is not used by the responder 204 to explicitly identify the lost frame. Therefore, the initiator 202 only needs to store the management messages by being included in the ACK policy field. A copy of the box until they are confirmed or they expire. In relation to a block ACK request (BAR) for managing a frame, the ACK policy field of the new MMPDU can be interpreted as a BAR. Alternatively, the φ a different MAC protocol data unit (MPDU) of the management frame can be used as a combination (that is, the combination of the two BAR frames: one for The data frame is sent in a part of the management frame, or alternatively, the BAR MPDU format can be extended to include an additional portion for managing the frame (also That is, the combination includes a BAR frame having two portions for the management frame and the data frame, respectively. Regarding a BA packet, a different bA MPDU for the management frame can be used as a combination (that is, the 14 M296548 containing 2 BA packets: one for the data frame and the other for the management message) A portion of the frame is sent, or alternatively, a conventional BA MPDU format can be extended to include an additional portion for confirming the management frame (ie, the containing one has a separate use) For the combination of the management frame and the two parts of the data frame, the BA and the BAR packets for managing the frame may be the same for the BA and BAR packets supporting the management frame. , φ or similar to the conventional frame format, and can be clearly identified by a single element, or a special field allocation, and the BA and BAR can use a one-dimensional map ( Bitmap ) is followed by a concept of a starting sequence number (SSN), wherein if the bit position η of the BA bit map is set to 1, it is determined that there is a sequence The control value is equal to the reception of the MPDU of BA SSN + η. Furthermore, if the one-bit position of the Α Α bitmap is set to 0, it is an indication that a MPDU φ sequence control value is equal to The MPDU of (BASSN + η) has not been successfully received. Typically, the combined management frame system is likely to have an increased SNs when there is a large gap between the SNs in the combined management frame. Time (eg, in conjunction with retransmitted frames and new frames), multiple BAs can be used, each combining to identify a different management frame, or multiple frames, for example, if the bit The map has a predefined maximum size (eg, 16 bits), and the combined management frames have more than 15 different sequential numbers, and they cannot be confirmed in the same bitmap. Also, another BA frame is necessary for 15 M296548. The BA and BAR systems can simply list the SN for each of the considered management frames. MQR frame, MCS feedback (MFB) frame To The Training Request (TRQ) frame, including the new fields, is described here as an example. However, it should be noted that any other management, control, or data frame may include These new frames are used to enhance the responsiveness of exchanging the packets. The MRQ chassis is a management frame of the type HT. The VIRQ frame is used to request MCS feedback from a responder 204. The MRQ frame, in addition to an MCS request block, as shown in the table, includes an ACK policy field, a request identification number field, a response time policy block, and a combination. At least one of the format fields, wherein the ACK policy block is set to "Non-ACK" (ie, requires a direct MFB frame response), or "ACK" (ie, an ACK packet is required), and if the Μ Β Β 吁 加以 加以 加以 加以 加以 加以 , , , , , , , , 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求 请求When sending more than one place, set it It is defined as "〇,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, , the responder 204 is expected to send a frame immediately (ie, 'in the SIFS range), if the response time policy is set to delay, the daykeeper 'the responder 204 It is expected that during the delay period specified by the 3MW MFB §fl box, if the response time policy is set to 16 M296548 "active provision", then the responder 204 can be in the responder 204. The response is sent at the selected time point, and the combined format interception can be set to "combined MAC protocol data unit (A-MPDU),, "RIFS_PPDU"', or "No-Aggregation", If the combined format interception is set to "A-MPDU", the responder 204 and the initiator 202 are expected to send an A-MPDU, and if the combined format is set to "RIFS_PPDU" "When, the response 204 and the initiator 202 are expected to use the rIFS to send multiple MPDUs, but may generate an A_MPDU, if the combined format intercept is set to "unbound (N〇_Aggregati〇n), The response state 204 and the initiator 202 are expected to not combine the frame.
