Figure 8 illustrates a low according to various embodiments presented herein. The submersible mode MDDI connection setting is 800. In the low latency mode, the channel configuration time can be determined based on inferences from the data contained in the packet in the forward and reverse directions. An MDDI transmitter 8 〇 2 can include a host 8 〇 4 and a portion of a user (Cl) 806. During the initialization phase, at 81 ,, the UWB modem on the transmitter 802 can send a mac: query to a sender MAC 808. The MAC query is a query that is sent to find the rate supported by the MAC and retransmission statistics. At 812, the sender MAC 8〇8 can be queried. This response may be a MAC response indicating the rate supported by the MAC retransmission statistics. Transmitter 802 requests a CTA setting 814 that lasts for a few milliseconds in the forward direction and a CTA of milliseconds in the reverse direction. The expected ratio of traffic to the opposite direction is W: «. At 816 'send-channel time request (cTRq) to PNC Mac 818. The -channel time response code can be sent in the reverse direction shown at 82 且 and in the forward direction shown at (2) and sent to a receiver MAC 824. As explained at 826, the MDm transmitter 8〇2 can initiate an MDDI transfer.

For the purpose of explanation, the ACK policy is assumed to be wack (the I7 is OK), and the latency of the forward link packet can be determined accordingly. The application latency limit in the pre-reverse link can be used to derive the duration of the MAC frame. For example, 'various algorithms, methods, and/or techniques can be used to continue the MAC frame.

Figure 9 'Description - for configuration - a traditionally wired device for communicating via a wire protocol and/or a wireless protocol. 9' at the end of the user's section - part Placed on the -MDDI Transmitter. The MDDI Transmitter 2 can be wireless and can be connected to a data source. (10) (1) The Transmitter can also include - a connection or interface to the (by) - a conventional wired connection link The MDm host of the client part. At 904, the second part of the user terminal is placed on one (four) to the receiver and the MDDI receiver can be called the wireless (10) receiver. The receiver can be connected to one ( For example, the display device #. The portion of the user terminal placed on the MDDI transmission n and the portion of the user terminal placed on the Na (1) receiver are different parts of the same user terminal. It should be noted that the user terminal should The individual Deng knife can be part of a processor, software, or combination thereof (eg, firmware). At 906 'provided - wired functionality and a wireless functionality. This function ΙΊ 3 enables the river_receiver to communicate via the wired power, the wireless functionality or two functionalities on the MDDI receiver. By way of example and not limitation, the MDm receiver may be capable of receiving a 128607.doc -26-200901719 communication (such as on a CRT screen or displaying a movie from _I „ for a movie) The mobile device can also be connected to a display to allow the movie to be displayed on the wall so that others can view the image. If the mobile device is more than capable, it can broadcast the movie on the display. And can be received or transmitted substantially simultaneously - different from the voice associated with the movie, so the user of the mobile device can enter L. ^ j enter - communication with the movie. Can be used - the example is In the case where a child of a user is watching a movie and wants to answer the phone and walk away. Therefore, the movie can be displayed by: and at the same time, the user can pass the wireless functionality at the same time: Or a method 1000 for determining a rate for a plurality of disclosed embodiments. In a helmet MDDI, for example, the MDDI operating rate depends in part on the rate of the wireless link. Method Hall begins Help, where the application data rate is queried to the host MAC (for example, the application data rate provided by the MAC can be queried by an MDDI host. / delete, " - round trip delay. At (10) 6 shots (4) the round trip delay test To determine or determine a forward link rate and a reverse link, the round trip delay measurement can be specified in a wire-to-call protocol that should be used according to some embodiments. The rate of operation may be calculated, in part, by comparing the forward link rate to the reverse link rate and determining the rate of the minimum of the two rates, which may be specified in the two rates. The minimum value is the operating rate. In some embodiments, the minimum of the two 128607.doc • 27-200901719 rates (forward link rate and reverse link rate) can be further advanced to the MDDI host. The maximum capacity and the maximum capacity of the MDDI client (a) are compared. The minimum or minimum rate based on this comparison is assigned as the operating rate. There should be a minimum allowable rate Rmin that can be established or pre-based based on the communication parameters. The right-calculated operating rate is lower than the minimum allowable rate', then f can be adjusted to increase the rate. At i 〇i ,, the operating rate is communicated or sent to a receiver (eg, MDDI receiver) In the above method 1000, for example, a transmitter can query the host MAC through a query module. The transmitter can further utilize the measurement module to measure the round trip. Delay 'determining the forward and reverse link rates and calculating the operating rate. The transmitter may also utilize the -communication component to transmit the operating rate to the receiver. It should be understood that 'the above is for illustrative purposes only and may be combined with the present disclosure Other components are utilized in one or more embodiments. Referring now to Figure 11', a description is given - in accordance with various embodiments presented herein: a method for communicating in a low-consumption mode. The forward link is shown on the left side of the figure and the reverse link is shown on the right side of the figure. At 11〇2, the forward link data is placed in a buffer. The data that can be placed in this buffer H excludes unnecessary information such as padding packets and/or round-trip delay packets. For example, this data can be placed in the buffer by the client side (C1) on the MDDI transmitter. A one-way CTA is requested at (10) ' (example * 'periodically or continuously). - Uwb mac can request this information from the sender to the 128607.doc -2S-200901719 receiver, for example, the size of the buffer. Forward link data can be sent at 1106. In the reverse direction, a host sends at least one reverse link encapsulation packet per frame. A subscriber (e.g., receiver) may specify the number of bytes that should be transmitted on the reverse link in the current frame. The host (e.g., the sender) can configure the request in a reverse link encapsulation packet. At U08, the reverse link data to be transmitted is placed in a buffer by, for example, an MDDI client (C2). The buffer can be located on one of the MDDI receiver UWB modems. At 111 由, for example, one on the receiver side of the 〇1; 霄8 data machine sends a request for a pair of reverse direction CTAs. The request may be for the CTAs in the reverse direction corresponding to the data that should be sent in the reverse direction. At 1112, an MDDI client (C2) on the receiver can preemptively send reverse link data to the client (C1) on the transmitter. As illustrated, at 1U4, a 2MDm client (C1) on the transmitter sends the data it has to the MDDI host in reverse-encapsulated packets. Figure 12 illustrates a method 12G() for communicating in a low latency mode in accordance with various embodiments presented herein. The forward link is shown on the left side of the figure and the reverse link is shown on the right side of the figure. During the initialization phase in the low latency mode, at 1202, a UWB modem on the transmitter (for example) requests a CTA of w milliseconds in the direction of the yaw. At KM, a CTA request for a duration of milliseconds is sent in the reverse direction. At 12〇6, it will be compared to the reverse CTA before receiving in response to the request. The expected ratio of traffic in the forward and reverse directions is w: „. It should be noted that (7) milliseconds corresponds to the duration of the MDDI forward link transfer rate for ^_ and: (m + n) < T CTAP < τ 128607.doc • 29- 200901719 The octave r-frame exceeds the frame duration, which can be determined by the latent time limit of the application.

In the reverse direction of the low latency nucleus period, the reverse link data is transmitted at 1208' during the CTA remaining in the reverse direction. At 121 ,, the duration of the MAC frame can be derived from the application of the latency limit in the forward and reverse links. In the following equation, the average number of retransmissions experienced by the A-line MAC frame. It corresponds to the size of the reverse link packet being sent and the physical layer transmission rate of the H-system MDDI data (MAC payload) for each reverse frame CTA duration. The physical layer 胄 、, MAC header and preamble of the physical layer transmission rate. - The size of the MAC plus the size of the ρ Η γ header plus the size of the preamble. SIFS is a short inter-frame spacing duration. The retransmission frame is spaced between the temples. . "The duration of the Ack # lose and the duration of the superframe (5). For explanatory purposes, the ACK policy is assumed to be Imm-ACK (Immediate Confirmation). Various algorithms, methods, and/or techniques can be utilized to determine the latency of the forward link packet accordingly. Depending on the arrival time of the reverse link data relative to the MAC frame, the transition may have the maximum latency expressed as:
