INSTRUCTIONS: This patent application claims the method and system for wireless universal serial bus transmission for the use of a large number of data transmission types of isochronous data under the title of February 7, 2008 (Method and System for Wireless USB Transfer of Isochronous Data using Bulk Data Transfer Type) " The Provisional Application No. 61/26,969, which has been assigned to its assignee and is hereby expressly incorporated by reference. Into this article. [Prior Art] The Wired Universal Serial Bus (USB) specification supports four basic types of data transfer: control, mass data, interrupt data, and isochronous data transfer. Control data transfer is used for burst, aperiodic, host soft start request/response communication, usually used for command/status operations. A large amount of data is transmitted as a non-periodic, large packet burst communication, usually used for any available bandwidth, and can be delayed until the bandwidth is available. For example. Printers that receive data from a large packet use a large number of transmission data types. Interrupt data transfer is used for low frequency, bounded latent communication. For example, a device such as a mouse or keyboard that will send very little data will use an interrupt data transfer pattern. The isochronous data transfer pattern (also known as streaming instant transfer) is used for periodic, continuous communication between the host and the device, and is typically used for time related information. Streaming devices, such as audio speakers, use isochronous data transfer patterns. The Wireless Universal Serial Bus (WUSB) specification includes descriptions and specifications for devices called wire adapters. These devices are wired USB to wireless usb adapters that allow "legacy" wired USB hosts and devices to be interconnected with WUSB devices in an extended USB system containing both wired and 138456.doc 200947210 wireless links. There are two types of wire adapters: a host wire adapter (HWA) and a device wire adapter (DWA) that operate in conjunction with one another. HWA has wired "upstream"USB埠 and wireless" downstream"WUSB埠, which allows wired USB hosts to communicate with WUSB devices. DWA has wireless "upstream" WUSB port and one or more wired"downstream"USB Oh, allowing the wired USB device to communicate with the WUSB host. Therefore, the WUSB system with "old version" wired USB host and device will use HWA and DWA. © WUSB specification supports the same data transfer type as wired USB. In detail, WUSB support control, large amount of data, interrupt data and etc. Time-based data transfer mode. WUSB mass data transfer maintains the simplicity of mass data transfer from wired USB. However, due to the nature of wireless communication, WUSB isochronous data transfer requires more complexity than wired USB isochronous data transfer. Accordingly, it would be desirable to have a method and system for providing isochronous data transfer to "legacy" wired USB devices using a large number of transfers over a wireless USB link. ® SUMMARY OF THE INVENTION A method and system for transmitting data in a WUSB system having a first USB enabled device and a second USB enabled device is provided. The method includes: providing a first data having a first data transfer pattern; converting the first data into a second data having a second data transfer pattern; and using the second data transfer pattern to Transmitting, by the first USB enabled device, the second USB enabled device; and converting the wirelessly transmitted second data into a third data having the first data transfer type. 138456.doc 200947210

DWA驅動器124判定對應於各別等時性資料封包212之封 138456.doc 200947210 包長度216。DWA驅動器124接著將封包長度216與等時性 貧料封包212組合。所得資料為具有大量資料傳送型式之 等時性資料214。在本揭示案之一實施例中,封包長度216 與對應的等時性資料封包212之組合為封包長度216與&對應 的等時性資料封包212之級聯。 ’ 此級聯‘針對等時性資料傳送210中之每一等時性資料封 包212而迭代地重複。在根據本揭示案之一實施例中, DWA驅動器124以使得每一封包長度先於對應的等時性資 料封包之方式來組合封包長度216與等時性資料封包212。 向HWA驅動器116提供具有大量傳送型式之等時性資料 214,以傳遞至HWA 112。 其後’ H WA 112使用大量資料傳送經由uwb鍵路122將 等時性資料214無線傳送至DWA 120。在DWA ι2〇接枚到 等時性資料214之後,DWA 120將資料214轉換回等時性資 料封包212 ’從而使資料封包212適合於傳遞至USB允用等 時性裝置128。 在本揭示案之一實施例中,DWA 120理解具有大量資料 傳送型式之等時性資料214為經聚集之等時性資料封包212 之大量傳送。因此,DWA 120使等時性資料封包212自具

200947210 亦參看圖4,其說明可在圖3之區塊32〇中使用之用於轉 換資料的方法的流程圖。該方法在區塊410中藉由判定對 應於複數個等時性資料封包之每一者的等時性資料封包長 度而開始。該方法在區塊420中藉由將該等等時性資料封 包長度與該複數個等時性資料封包組合使得每一等時性資 料封包長度先於對應的等時性資料封包而繼續。 亦參看圖5,其說明可在圖3之區塊34〇中使用之用於轉 換資料的方法的流程圖.該方法包括使複數個等時性資料 β 封包自第二資料(諸如具有大量傳送型式之等時性資料)分 離。 在替代實施例中,返回參看圖2,可以較高優先權標記 具有大量資料傳送型式之等時性資料214,從而促進其在 WUSB異動中較之其他資料傳送型式較早傳遞。舉例而 言,圖2中所說明之大量資料傳送218被提供至dwa驅動器 124。如上文所論述,具有等時性資料傳送型式之等時性 參資料210傳送亦被提供至DWA驅動器124。在等時性資料傳 送210轉換為具有大量資料傳送型式之等時性資料SB之 後,DWA驅動器124以較高優先權標記所得等時性資料 214,以在WUSB資料傳送2〇〇中優先於其他資料傳送型式 傳遞。大量資料220及具有大量資料傳送型式之等時性資 料214兩者被k供至η WA驅動器116。H WA驅動器116辨識 等時性資料214之優先權,且因此促進具有大量資料傳送 型式之等時性資料214在大量資料22〇之前傳遞至dwa 120 〇 138456.doc 12 200947210 根據某些實施例,導線轉接器驅動器(例如,DWA驅動 器124及/或HWA驅動器116)可確保含有等時性資料之大量 資料與其他大量資料相比被給予較高優先權。舉例而言, 當使用導線轉接器時,導線轉接器驅動器可執行排程功能 以判定哪一訊務被排程為下一個。因此,在此排程期間, 導線轉接器驅動器可藉由將含有等時性資料之大量資料封 包排程為在其他大量資料之前傳送來實施優先化。 根據某些實施例’可藉由將含有等時性資料之大量資料 封包插入在其他佇列之前的被服務之高優先權佇列,來給 予該等大量資料封包較高優先權。根據某些實施例,為提 供對優先化之進一步確保,WUSB主機亦可在其排程演算 法中啟用含有等時性資料之大量資料封包之優先化。 根據某些實施例,可藉由實際地延遲來自該等佇列中之 一或多者之傳送,來達成佇列之優先權。舉例而言,可藉 由監視DWA及/或HWA中之記憶鱧使用來偶爾限制(習知) 大量資料仔列(用於傳送不含有等時性資料封包之大量資 料)傳送。在偵測到記憶體使用時,大量資料佇列可延 遲,從而自高優先權佇列釋放頻寬以供傳送大量資料封包 (含有等時性資料之潛在較小大量資料封包)。 某些型式之資料傳送不可重新配置或分裂。因此,對於 某些實施例,D WA驅動器可在不繞過大量資料佇列中之任 何資料封包(例如,其中繞過將導致分裂 時性資料有效負㈣例而言,若大量資料== 送對由DWAS始之資料封包的傳送請求標頭,則在某些情 138456.doc -13- 200947210 況下,根據至dwa之導線轉接器協定,該異動不可自其資 料有效負載分裂。因此’在該等情況下,可使用兩個標記 來將封包自DWA驅動器傳輸至HWA驅動器:用以指示優 先權之第一標記,以及用以指示分裂能力之第二標記。 根據某些實施例,發送至HWA驅動器之每一大量資料傳 送可具有I/O請求封包(IRP),該I/O請求封包含有大量資料 傳送之上下文資訊。根據某些實施例,可設定IRp中經保 留以用作優先權糊位之特定搁位,以指示含有等時性資料 ® 封包之大量資料傳送之高優先權。 本揭示案之替代實施例可包括如圖1中所示之WUSB系 統,其具有USB允用等時性裝置,該裝置為音訊麥克風。 其他實施例可包括支援串流即時資料傳送之USB允用裝 置。另外,在替代實施例中,圖1中所示之WUSB系統中之 USB允用主機11〇可任選地包括本機冒11!§3允用主機,因此 消除了對HWA 112之需要。此外,在根據本揭示案之另一 φ 替代實施例中,圖1甲所示之WUSB系統100中之USB允用 等時性裝置128包括本機WUSB允用等時性裝置,因此消除 了對DWA 120之需要。 此外,在又一替代實施例中,圖iiUWB系統1〇〇支援源 自DWA 120且使用大量資料傳送將等時性資料無線傳送至 HWA 112之等時性資料傳送。 實例封包轉換 如上文所述’由於無線通信之性質,wusb等時性資料 傳送相對於有線聰等時性資料傳送而言需要增加的複雜 138456.doc 200947210 Ίΐ然而’本揭示案之某些實施例可允許使用無線USB大 送二枓傳送操作在主機與則裝置之間的等時性資料傳 使用本文所呈現之技術,可利用無線USB大量資料傳送 . 來達成主機與刪允用等時性裝置之間的等時性資料傳 送如同其經由有線USB連接件直接連接。 如上文所述,對於某些實施例,當準備將資料自等時性

It should be understood that any aspect of the invention disclosed herein may be embodied by one or more elements of a claim. The word "exemplary" is used herein to mean "serving as an example, instance, or description. Any aspect described herein as "exemplary" is not necessarily to be construed as preferred over other states 138456.doc 200947210 or Advantageous Beta This disclosure relates generally to the transmission of isochronous data using a large number of data transfer patterns in a wireless USB (WUSB) system. It should be understood, however, that the disclosure provides many different embodiments or examples for the various features of the invention. Specific examples of components and configurations are described below to simplify the disclosure. Of course, these situations are merely examples and are not intended to be limiting. In addition, the present disclosure may repeat reference numerals and/or letters in the examples. This repetition is for the purpose of simplicity and clarity, and is not intended to be a limitation of the various embodiments and/or configurations described. Referring to Figure 1, System 1 is an example of a WUSB system that may benefit from one or more embodiments of the present disclosure. The system includes a USB enabled host device 110, such as a computer or laptop having at least one USB port. The host 110 is connected to a host wire adapter (HWA) 112 via a USB port. The host 11A and the HWA 112 communicate via the USB cable 114. The HWA 112 provides WUSB functionality to the host 110. Host 110 includes an HWA driver 116 that provides software that facilitates communication involving HWA 112. HWA 112 includes a wireless transceiver in HWA 112 that uses transceiver 118 to wirelessly communicate with device wire adapter (DWA) 120 via wireless link 122. 11\^\112 uses the 1;86 protocol to communicate with 0\^120. The wireless link 122 is built on the ultra wideband (UWB) spectrum. Those skilled in the art will appreciate that instead of utilizing a transceiver, separate components can be utilized for transmission (e.g., 'transmitters) and receiving (e.g., receivers). Host 110 further includes a DWA driver 124 that facilitates communication involving DWA 120. The DWA 120 has a wireless transceiver 126 for communicating via the 138456.doc 200947210 WA transceiver i18: ^hwa 112. DWA i2 is connected to the uSB to allow isochronous devices 128' such as USB audio speakers. The temporal device 128 and the DWA 120 include isochronous endpoints 132 and 134, respectively, which facilitate isochronous transfers between the device and the isochronous device 128. The DWA 12 further includes an isochronous scheduler 136 that facilitates isochronous transfer from the DWA 12 to the isochronous device 128. In particular, scheduler 136 transmits isochronous data transfers in a time-based manner. Referring also to Fig. 2', there is illustrated a graphical representation of the data being transmitted in accordance with the embodiment. For example, the graphical representation 2 can be implemented in a circular system. For the sake of clarity, the similar features in Figures i and 2 are the same. Initially, DWA driver 124 identifies and enumerates USB isochronous device 128. Thereafter, the DWA driver 124 will be declared as an isochronous transfer type of wire adapter remote tube mapped to the DWA 12's isochronous endpoint associated with the USB isochronous device 128 to be declared A wire adapter distal tube that is of the isochronous delivery type. In addition, the DWA 12 sets the isochronous 0 endpoint 13 4 on the DWA 12 to an isochronous scheduled endpoint. The USB enabled host device 11 (such as a laptop computer) can use the isochronous device 128s to request isochronous data transfer to the usb. When the host i makes an isochronous data transfer request, An isochronous data transfer 210 having an isochronous data transfer pattern is provided to the dWA driver 124. The isochronous data transfer 210 consists of an isochronous data packet 212. The DWA driver 124 converts the isochronous data packet 212 into isochronous data having a plurality of data transfer patterns. The 214 ° DWA driver 124 determines the package length 216 corresponding to the respective isochronous data packet 212 138456.doc 200947210. The DWA driver 124 then combines the packet length 216 with the isochronous poor packet 212. The resulting data is isochronous data 214 with a large number of data transfer patterns. In one embodiment of the present disclosure, the combination of the packet length 216 and the corresponding isochronous data packet 212 is a concatenation of the packet length 216 and the isochronous data packet 212 corresponding to & This cascading is iteratively repeated for each isochronous data packet 212 in the isochronous data transfer 210. In an embodiment in accordance with the present disclosure, DWA driver 124 combines packet length 216 and isochronous data packet 212 in such a manner that each packet length precedes the corresponding isochronous packet. The HWA driver 116 is provided with isochronous data 214 having a large number of transmission patterns for delivery to the HWA 112. Thereafter, the HWA 112 wirelessly transmits the isochronous data 214 to the DWA 120 via the uwb key path 122 using a large amount of data transfer. After the DWA ι2 is spliced to the isochronous data 214, the DWA 120 converts the data 214 back to the isochronous data packet 212' to cause the data packet 212 to be suitable for delivery to the USB enabled isochronous device 128. In one embodiment of the present disclosure, DWA 120 understands that isochronous data 214 having a large number of data transfer patterns is a bulk transfer of aggregated isochronous data packets 212. Thus, DWA 120 separates isochronous data packets 212 from isochronous data 214 having a large number of data transfer patterns. The DWA 12 passes the resulting isochronous data packet 212 to the isochronous endpoint U4 on the DWA 120 to meter out the delivery of the isochronous data packet 212 based on the isochronous scheduler ι36. According to some embodiments, the scheduler 136 can measure the isochronous data packet based on the quality of service defined by the isochronous endpoint to which the data is forwarded and/or the number of traffic parameters 138456.doc _ 10-200947210 Pass. The 'DWA 1 20 causes the original isochronous data packet 2 12 to be separated from the isochronous data 214 having a large number of data transfer patterns. After the DWA 120 completes the conversion of the received isochronous data 2 14 to the isochronous data packet 212, the DWA 120 may pass the original isochronous data packet 212 to the USB enabled isochronous device 128. Referring also to Fig. 3, a flow diagram of a method 300 for wirelessly transmitting data, which can be implemented in the system of Fig. 1, is illustrated in accordance with an embodiment. The operation of FIG. 3 can be performed according to certain embodiments to perform wireless transfer of data between the host and the USB device using a USB mass transfer operation, as if using isochronous buck transfer operations via direct between the host and the device (wired ) The link is transmitted. Figure 6 illustrates a diagram of an example packet parent switch between a host device and a USB enabled device via a radio link between 11|eight and eight, corresponding to the operation illustrated in Figure 3. The method 300 begins in block 3 _0 by providing first data (the isochronous data) having a first data transfer pattern (such as an isochronous data transfer pattern). In block 320, method 3 continues by converting the first data to a second material (such as isochronous data) having a second data transfer pattern (such as a bulk transfer pattern). The method 3 continues in block 33 by wirelessly transmitting the second data from the first USB enabled device (such as HWA) to the second deleted device (such as dwa) by using the second data transfer pattern. The method 300 continues by converting the wirelessly transmitted second data to a third material (such as isochronous data) having a first data transfer pattern. 138456.doc 200947210 Referring also to Figure 4, a flow diagram of a method for translating data that can be used in block 32 of Figure 3 is illustrated. The method begins in block 410 by determining the isochronous data packet length corresponding to each of the plurality of isochronous data packets. The method continues in block 420 by combining the isochronous data packet length with the plurality of isochronous data packets such that each isochronous data packet length precedes the corresponding isochronous data packet. Referring also to Figure 5, a flow diagram of a method for converting material that can be used in block 34 of Figure 3 is illustrated. The method includes packetizing a plurality of isochronous data β from a second material (such as having a large number of transfers) Isochronic data of the type) separation. In an alternate embodiment, referring back to Fig. 2, isochronous data 214 having a large number of data transfer patterns can be marked with higher priority, thereby facilitating its early delivery in WUSB transactions over other data transfer patterns. For example, the bulk data transfer 218 illustrated in FIG. 2 is provided to the dwa driver 124. As discussed above, isochronous data 210 transmissions having isochronous data transfer patterns are also provided to DWA driver 124. After the isochronous data transfer 210 is converted to the isochronous data SB having a large number of data transfer patterns, the DWA driver 124 marks the obtained isochronous data 214 with a higher priority to take precedence over the WUSB data transfer. Data transfer type delivery. Both the bulk data 220 and the isochronous data 214 having a large number of data transfer patterns are supplied to the η WA driver 116. The H WA driver 116 recognizes the priority of the isochronous data 214, and thus facilitates the isochronous data 214 with a large number of data transfer patterns to be passed to the dwa 120 大量 138456.doc 12 200947210, according to some embodiments, Wire adapter drivers (e.g., DWA driver 124 and/or HWA driver 116) can ensure that a large amount of data containing isochronous data is given a higher priority than other large amounts of data. For example, when using a wire adapter, the wire adapter driver can perform a scheduling function to determine which traffic is scheduled to the next. Therefore, during this scheduling, the wire adapter driver can implement prioritization by scheduling a large number of data packets containing isochronous data to be transmitted before other large amounts of data. According to some embodiments, a large number of data packets can be given a higher priority by inserting a large number of data packets containing isochronous data into the served high priority queues. In accordance with certain embodiments, to provide further assurance of prioritization, the WUSB host may also enable prioritization of a large number of data packets containing isochronous data in its scheduling algorithm. According to some embodiments, the priority of the queue can be achieved by actually delaying the transmission from one or more of the queues. For example, the use of memory in DWA and/or HWA can be used to occasionally limit (practice) the transmission of large amounts of data (used to deliver large amounts of data that do not contain isochronous data packets). When memory usage is detected, a large number of data queues can be delayed, thereby freeing bandwidth from high priority queues for transmission of large data packets (potentially small data packets containing isochronous data). Some types of data transfer are not reconfigurable or split. Thus, for some embodiments, the DWA driver can bypass any data packets in a large number of data queues (eg, where bypassing will result in split-time data being negative (4), if a large amount of data == For the transmission request header of the data packet starting from DWAS, in some cases 138456.doc -13- 200947210, according to the wire adapter agreement to dwa, the transaction cannot be split from its data payload. In such cases, two flags can be used to transfer the packet from the DWA driver to the HWA driver: a first flag to indicate priority, and a second flag to indicate splitting capability. According to some embodiments, Each bulk data transfer to the HWA driver may have an I/O request packet (IRP) containing context information for a large amount of data transfer. According to some embodiments, the IRp may be set to be reserved for use as a priority. A specific placement of the right margin to indicate a high priority for the bulk of the data transfer containing the isochronous data® packet. An alternative embodiment of the present disclosure may include a WUSB system as shown in FIG. There is a USB enabled isochronous device, which is an audio microphone. Other embodiments may include a USB enabled device that supports streaming instant data transfer. Additionally, in an alternative embodiment, the WUSB system shown in Figure 1 The USB enable host 11 can optionally include the local device 11! § 3 to permit the host, thus eliminating the need for the HWA 112. Further, in another alternative embodiment according to the present disclosure, Figure 1A The USB enabled isochronous device 128 in the illustrated WUSB system 100 includes a native WUSB enabled isochronous device, thus eliminating the need for the DWA 120. Further, in yet another alternative embodiment, Figure iiUWB system 1 〇〇 Support for isochronous data transfer from DWA 120 and wireless transmission of isochronous data to HWA 112 using mass data transfer. Example packet conversion as described above ' Due to the nature of wireless communication, wusb isochronous data transfer is relative The complexity of the need for wireline transmission is 138456.doc 200947210. However, certain embodiments of the present disclosure may allow for the use of wireless USB transmission between the host and the device. Temporal data transmission Using the technology presented in this paper, wireless USB can be used for mass data transfer to achieve isochronous data transfer between the host and the isochronous device as if it were directly connected via a wired USB connector. According to some embodiments, when preparing to convert the data from the isochronous #transmission type into a large data transmission type, the data packet length may be cascaded with the plurality of isochronous data packets in a plurality of data streams. The wireless data deletion can be used to transmit isochronous data packets and their respective lengths. When receiving a large amount of data embedded in an isochronous data packet, the data packet length allows the receiving entity to extract the corresponding isochronous time. Sexual data packet. For example, the receiving entity can read the data packet length and read the subsequent number of bytes of the corresponding data packet. Figures 6A and 6B illustrate how an isochronous data packet can be converted to a data packet suitable for a large φ quantity > material transfer. Figure 6A illustrates the isochronous data transfer 210 of the data packet 212. Each data packet 212 has a corresponding length L (e.g., data packet D1 has a length. Data packet D2 has a length L2', etc.). For example, a data packet can be transmitted to the host wire adapter using a conventional isochronous data transfer with a data packet (D1 to DN) followed by (10). For isochronous data transfers, the length of each data packet can vary. As illustrated in Figure 6B, the isochronous data packet 212 (〇1 to 〇)^ can be converted to a plurality of data streams 214 having a data packet length 216 concatenated thereto. 138456.doc 200947210 The isochronous data packet 212 can then be transmitted via a bulk data transfer (e.g., D1,) of the packet. For large data transfers, the maximum data packet length (LMAX) can be used for each transfer when possible. A packet smaller than the maximum data packet length can signal the end of a large amount of data transmission. Thus, the number of large data transfers required to transmit the isochronous data packet 212 and its corresponding data packet length may vary with lmax and the actual length of each data packet 212. For some embodiments, the receiving device can generate an ACK packet to confirm receipt of the bulk transmission. However, in order to support the isochronous nature of data transfer, the requirement to retransmit a packet with a bit error (eg, as indicated by a mismatch with the CRC) may be ignored, and a portion or a known portion of the packet may be known. The processing of the packet (eg, corresponding to silence in the transmission of audio or voice data) is not considered. As mentioned above, for some embodiments, a large amount of data transfer containing isochronous data packets can be marked with higher priority than other large amounts of data, and the data is sufficient to satisfy the negotiation between the host and the device. The bandwidth and the rate required for the latency. In accordance with some embodiments, each of the plurality of data transfers sent to the device may have an I/O request packet (IRP) that contains context information for a large amount of data transfer. According to some embodiments, a particular shelf in the IRP that is reserved for use as a priority shed can be set, with a higher priority of bulk data transfer that does not contain isochronous data packets. Additionally, for certain embodiments Other large amounts of information may be included in the bulk of the data transfer containing isochronous data packets. Any suitable technique may be utilized in these embodiments to distinguish between isochronous data packets and other bulk data 138456.doc -16 - 200947210 packets. 7 illustrates an example operation for isochronous (〇υτ) data transfer from a host to a device via wireless USB mass data in accordance with certain aspects of the present disclosure. Such operations include operations 602 through 604 that may be performed at the host device (eg, by a DWA driver, HWA driver, or HWA) and operations that may be performed at the USB enabled device (eg, by a DWA or DWA scheduler) 612 to 616 » e These operations begin at 602 by obtaining an isochronous data packet. The isochronous data packet can be obtained, for example, by an isochronous device driver (which can be executed prior to the DWA driver) that obtains an isochronous data packet from the application. The isochronous data packet may correspond to, for example, streaming audio (e.g., music: a handset or a phone application) or video. At 6 () 4, the data packet transmission and data packet length are transmitted using wireless deletion of a large amount of data transmission. At 6 U, a large amount of data transfer is received, and at 614, an isochronous data packet is extracted from the mass data transfer using the data packet length. For example, the receiving device can read the data packet length and extract the subsequent corresponding number of bytes as an isochronous data packet, and repeat the process to repeat the remaining packets. At 616, the (four) knowledge is made to delete the isochronous data packet to the device. Figure 8 illustrates a diagram of an isochronous (Xie) data transfer from a host to a device via a wireless coffee mass transfer corresponding to the operation of Figure 7. For example, the stream 2 of the isochronous data packet 212 can be converted into a large amount of assets having the isochronous level associated with the corresponding data packet length... From [iWH2, a large amount of capital (four) can be sent to 21 138456. Doc 200947210 to DWA 120. At DWA 12, the isochronous data packet 212 can be extracted and transmitted to the USB enabled isochronous device 128. For example, the DWA 120 scheduler 136 shown in the figure can buffer the isochronous data packet received via the wireless USB mass data transmission, and transmit the isochronous data packet to the USB according to the negotiated rate. Isochronous Device 128 ° is illustrated. Figure 9 illustrates an example operation for isochronous (IN) data transfer from a device to a host via wireless usb mass data in accordance with certain aspects of the present disclosure. Such operations include operations 8〇2 to 8〇4 that may be performed at a USB enabled device (eg, by a scheduler of DWA or DWA), and operations 812 that may be performed at the host device (eg, 'by HWA') To 816. These operations begin at 802 by transmitting isochronous data packets using wired USB isochronous data transfer. At 8〇4, wireless USB data transmission is used to transmit isochronous data packets and data packet lengths. At 812, a large amount of data transfer is received, and at 814, an isochronous data packet is extracted from the mass data transfer using the data packet length. At 816, isochronous data packets are transmitted to the device using (preferred) wired USB isochronous data transfer. Figure 10 illustrates a diagram of an example isochronous (OUT) data transfer from a device to a host via a wireless USB mass data transfer operation corresponding to the operation of Figure 9. As illustrated, the stream 21 from the isochronous data packet 212 of the device 128 can be converted into a bulk data transport stream 214 having an isochronous data packet 212 and a corresponding data packet length 216 concatenated thereto. The DWA 120 can transmit a large number of data transport streams 214 to the HWA 112. The HWA 112 can transfer a large amount of data transfer I38456.doc • 18 - 200947210 214 to the HWA drive and the DWA drive, and for example, the DWA drive can be extracted to the host 120. The isochronous data packet 212. The isochronous data packet can be transmitted to the host in a meterable manner (for example, by buffering the isochronous data packet received via the wireless USB mass data transfer and transmitting it to the host 12's scheduler application at a negotiated rate) 12〇.
