發明領域 Field of invention

實施例係關於無線網路。一些實施例係關於無線區域網路(WLAN)、Wi-Fi網路及根據IEEE 802.11標準之一操作的網路,該等IEEE 802.11標準諸如IEEE 802.11ac標準或IEEE 802.11ax SIG(稱為DensiFi)。一些實施例係關於高效能無線通訊或高效能WLAN(HEW)通訊。 Embodiments relate to wireless networks. Some embodiments relate to wireless local area networks (WLANs), Wi-Fi networks, and networks operating in accordance with one of the IEEE 802.11 standards, such as the IEEE 802.11ac standard or the IEEE 802.11ax SIG (referred to as DensiFi). . Some embodiments relate to high performance wireless communication or high performance WLAN (HEW) communication.

發明背景 Background of the invention

被稱為高效能WLAN(HEW)的IEEE 802.11ax為IEEE 802.11ac標準之後續,且意欲提高無線區域網路(WLAN)之效能。HEW之目標在於提供IEEE 802.11ac標準之多達四倍或更大通量。HEW可在高密度熱點及蜂巢式卸載情形中為尤其適合的,其中競爭無線媒體的許多裝置可具有低至適度資料速率要求。Wi-Fi標準已自IEEE 802.11b演進至IEEE 802.11g/a,演進至IEEE 802.11n,演進至IEEE 802.11ac,且現演進至IEEE 802.11ax。在此等標準之每一演變中,存在用以提供與先前標準之共存的機構。對於HEW,與此等舊有標準共存的相同要求存在。HEW之一問題為頻寬之有效分配及使用。 IEEE 802.11ax, known as High Efficiency WLAN (HEW), is a successor to the IEEE 802.11ac standard and is intended to improve the performance of wireless local area networks (WLANs). The goal of HEW is to provide up to four times or more throughput of the IEEE 802.11ac standard. HEWs are particularly suitable in high density hotspots and cellular offload scenarios where many devices competing for wireless media can have low to moderate data rate requirements. The Wi-Fi standard has evolved from IEEE 802.11b to IEEE 802.11g/a, evolved to IEEE 802.11n, evolved to IEEE 802.11ac, and is now evolving to IEEE 802.11ax. In each of these standards, there are mechanisms for providing coexistence with previous standards. For HEW, the same requirements exist for coexistence with these old standards. One of the problems with HEW is the efficient allocation and use of bandwidth.

因此,存在對允許HEW裝置與舊有裝置共存的系統及方法之一般需求。亦存在對允許HEW裝置與舊有裝置共存且更有效地分配並使用可利用的頻寬的系統及方法之一般需求。 Therefore, there is a general need for systems and methods that allow HEW devices to coexist with legacy devices. There is also a general need for systems and methods that allow HEW devices to coexist with legacy devices and to more efficiently allocate and use available bandwidth.

較佳實施例之詳細說明 Detailed description of the preferred embodiment

以下描述及圖式充分地例示特定實施例以允許熟習此項技術者實踐該等實施例。其他實施例可併入結構、邏輯、電氣、過程及其他變化。一些實施例之部分及特徵可包括於其他實施例之該等部分及特徵中,或由其他實施例之該等部分及特徵替代。申請專利範圍中所闡述之實施例涵蓋該等請求項之所有可利用的等效物。 The following description and the drawings are merely illustrative of specific embodiments of the embodiments Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in, or substituted for, those portions and features of other embodiments. The embodiments set forth in the scope of the patent application cover all available equivalents of the claims.

圖1例示根據一些實施例之HEW網路。HEW網路100可包括主站(STA)102、多個HEW站104(HEW裝置)及多個舊有裝置106(舊有站)。主站102可經配置以根據IEEE 802.11標準中一或多個與HEW站104及舊有裝置106通訊。根據一些HEW實施例,主站102及HEW站104可根據IEEE 802.11ax標準通訊。根據一些HEW實施例,存取點102可作為主站操作,該主站可經配置以爭用無線媒體(例如,在競爭週期期間)以便針對HEW控制週期(亦即,發射機會(TXOP))接收媒體之排斥控制。主站可在HEW控制週期開始時發射HEW主同步發射。在HEW控制週期期間,排定HEW站104可根據基於非競爭的多重存取技術與主站通訊。此不同於裝置根據基於競爭的通訊技術而非多重存取技術通訊的習知Wi-Fi通訊。在HEW控制週期期間,主站可使用一或多個HEW訊框與HEW站通訊。在HEW控制週期期間,舊有站避免通訊。在一些實施例中,主同步發射可被稱為HEW控制及排程發射。 FIG. 1 illustrates a HEW network in accordance with some embodiments. The HEW network 100 can include a primary station (STA) 102, a plurality of HEW stations 104 (HEW devices), and a plurality of legacy devices 106 (legacy stations). The primary station 102 can be configured to communicate with the HEW station 104 and the legacy device 106 in accordance with one or more of the IEEE 802.11 standards. According to some HEW embodiments, the primary station 102 and the HEW station 104 can communicate in accordance with the IEEE 802.11ax standard. According to some HEW embodiments, the access point 102 can operate as a primary station that can be configured to contend for wireless media (e.g., during a contention period) to control the period for the HEW (i.e., the transmitter (TXOP)) Receive media exclusion controls. The primary station can transmit HEW primary synchronous transmissions at the beginning of the HEW control period. During the HEW control period, the scheduled HEW station 104 can communicate with the primary station in accordance with a non-contention based multiple access technique. This is different from conventional Wi-Fi communication in which the device communicates based on contention-based communication technologies rather than multiple access technologies. During the HEW control period, the primary station can communicate with the HEW station using one or more HEW frames. Old stations avoid communication during the HEW control cycle. In some embodiments, the primary synchronization transmission may be referred to as HEW control and scheduled transmission.

在一些實施例中,在HEW控制週期期間使用之多存重取技術可為排定正交分頻多重存取(OFDMA)技術, 然而此並非必要條件。在一些實施例中,多重存取技術可為分時多重存取(TDMA)技術或分頻多重存取(FDMA)技術。在一些實施例中,多重存取技術可為分空間多重存取(SDMA)技術。在控制週期期間的通訊可為上行鏈路通訊或下行鏈路通訊。 In some embodiments, the multiple access re-acquisition technique used during the HEW control period may be an Orthogonal Frequency Division Multiple Access (OFDMA) technique, However, this is not a requirement. In some embodiments, the multiple access technology may be a Time Division Multiple Access (TDMA) technique or a Frequency Division Multiple Access (FDMA) technique. In some embodiments, the multiple access technology may be a sub-space multiple access (SDMA) technique. The communication during the control period can be uplink communication or downlink communication.

主站102亦可根據舊有IEEE 802.11通訊技術與舊有站106通訊。在一些實施例中,主站102亦可為可組配的,以根據舊有IEEE 802.11通訊技術在HEW控制週期之外與HEW站104通訊,然而此並非必要條件。 The primary station 102 can also communicate with the legacy station 106 in accordance with the legacy IEEE 802.11 communication technology. In some embodiments, the primary station 102 can also be configurable to communicate with the HEW station 104 outside of the HEW control period in accordance with the legacy IEEE 802.11 communication technology, although this is not a requirement.

在一些實施例中,HEW訊框之資料欄位可經組配成具有相同頻寬,且頻寬可為20MHz、40MHz或80MHz相連頻寬或80+80MHz(160MHz)非相連頻寬之一。在一些實施例中,可使用320MHz相連頻寬。在此等實施例中,HEW訊框之每一資料欄位可經組配以用於發射若干空間串流。在一些實施例中,HEW訊框之資料欄位可在OFDMA子通道內通訊,該等OFDMA子通道具有一或多個最小頻寬單元。以下更詳細地論述此等實施例。 In some embodiments, the data fields of the HEW frame can be grouped to have the same bandwidth, and the bandwidth can be one of a 20 MHz, 40 MHz, or 80 MHz connected bandwidth or a 80+80 MHz (160 MHz) non-contiguous bandwidth. In some embodiments, a 320 MHz connected bandwidth can be used. In these embodiments, each data field of the HEW frame can be assembled for transmitting a number of spatial streams. In some embodiments, the data field of the HEW frame can be communicated within an OFDMA subchannel having one or more minimum bandwidth units. These embodiments are discussed in more detail below.

在一些實施例中,發射傳訊結構用來攜帶封包資訊(例如,HEW訊框)以組配裝置(例如,HEW站104)以便解調封包之一特定部分且/或以組配裝置以便使用特定OFDMA及MU-MIMO資源發射或接收。在一些實施例中,封包之該特定部分可包含一或多個20MHz頻寬結構(例如,通道)之一或多個最小頻寬單元。每一20MHz頻寬結構可包含若干最小頻寬單元以允許每一20MHz片段具有相較 於20MHz之較小粒度。本文所揭示之一些實施例可提供傳訊設計以在諸如高效能WLAN(HEW)的下一代Wi-Fi標準(亦即,IEEE 802.11ax任務組)中組配OFDMA接收器,然而實施例之範疇在此方面不受限制。 In some embodiments, the transmit messaging structure is configured to carry packet information (eg, HEW frame) to assemble devices (eg, HEW station 104) to demodulate a particular portion of the packet and/or to assemble the device for use with a particular OFDMA and MU-MIMO resources are transmitted or received. In some embodiments, the particular portion of the packet can include one or more of the minimum bandwidth units of one or more 20 MHz bandwidth structures (eg, channels). Each 20MHz bandwidth structure can include several minimum bandwidth units to allow each 20MHz segment to have a comparison Smaller particle size at 20MHz. Some embodiments disclosed herein may provide a messaging design to assemble an OFDMA receiver in a next generation Wi-Fi standard such as High Efficiency WLAN (HEW) (ie, IEEE 802.11ax task group), however the scope of the embodiments is There is no limit to this.

因為HEW之一主要使用狀況為許多裝置試圖以適度資料速率存取媒體的密集佈署,所以需要允許較多同時存取裝置的技術。當前IEEE 802.11ac規格允許具有八個同時多輸入多輸出(MIMO)串流的高達160MHz頻寬。HEW之焦點在於使用該寬頻寬來提供對許多裝置之存取。本文所揭示之一些實施例定義發射傳訊結構,該發射傳訊結構攜帶封包資訊以組配OFDMA接收器且/或以組配藉由接收端處之裝置的即將出現的OFDMA發射。 Since one of the primary use cases of HEW is that many devices attempt to access dense deployment of media at moderate data rates, there is a need for techniques that allow for more simultaneous access devices. The current IEEE 802.11ac specification allows for up to 160 MHz bandwidth with eight simultaneous multiple input multiple output (MIMO) streams. The focus of the HEW is to use this wide bandwidth to provide access to many devices. Some embodiments disclosed herein define a transmit messaging structure that carries packet information to assemble an OFDMA receiver and/or to assemble an upcoming OFDMA transmission by a device at the receiving end.

本文所揭示之一些實施例定義有效的、可擴展的且可由在20MHz模式中操作之裝置解碼的發射傳訊結構,迄今在DensiFi或IEEE中之其他建議未提供該發射傳訊結構。根據一些實施例,發射結構經組配來攜帶封包資訊以組配OFDMA接收器,使得接收器可解調封包之一特定部分(例如,特定OFDMA資源及/或MU-MIMO串流),且/或以組配接收器來使用特定OFDMA及MU-MIMO資源發射。本發明結構可使用20MHz頻寬之最小值,且該結構為模組化的且可擴展至較高頻寬,該等較高頻寬為20MHz之倍數(例如,舊有Wi-Fi操作頻寬40MHz、80MHz及160MHz)。每一20MHz結構可繼而組配一或多個最小頻寬單元之OFDMA子通道。此等實施例允許組配HEW站104將針對上 行鏈路方向上之OFDMA通訊且針對下行鏈路方向上之OFDMA通訊獲組配。 Some embodiments disclosed herein define transmit transmit structures that are efficient, scalable, and decodable by devices operating in the 20 MHz mode, and other proposals in DensiFi or IEEE to date have not provided the transmit transmit structure. In accordance with some embodiments, the transmit structure is configured to carry packet information to assemble an OFDMA receiver such that the receiver can demodulate a particular portion of the packet (eg, a particular OFDMA resource and/or MU-MIMO stream), and / Or use a specific OFDMA and MU-MIMO resource transmission in combination with the receiver. The structure of the present invention can use a minimum of 20 MHz bandwidth, and the structure is modular and can be extended to a higher bandwidth, which is a multiple of 20 MHz (for example, the old Wi-Fi operating bandwidth is 40 MHz, 80 MHz, and 160MHz). Each 20 MHz structure can then be combined with one or more OFDMA subchannels of the smallest bandwidth unit. These embodiments allow the grouping HEW station 104 to be targeted The OFDMA communication in the downlink direction is matched and the OFDMA communication in the downlink direction is matched.

HEW之一設計目標在於採用方法來改良Wi-Fi之效能,且具體而言改良密集佈署之效能。基於HEW之此目標,提出用以改良實體層(PHY)效能之技術,諸如OFDMA技術。本文所揭示之實施例提供可使用以便組配OFDMA接收器的新封包結構。 One of the goals of HEW is to adopt methods to improve the performance of Wi-Fi and, in particular, to improve the performance of dense deployment. Based on this goal of HEW, techniques for improving the performance of physical layer (PHY), such as OFDMA technology, are proposed. Embodiments disclosed herein provide a new packet structure that can be used to assemble an OFDMA receiver.

圖2A例示舊有封包結構。在圖2A中可看出,在IEEE 802.11ac中,VHT-SIG-A在每一20MHz通道202中經複製。另外,VHT-SIG-A發射使用含有僅48個資料副載波的IEEE 802.11a相容波形。 Fig. 2A illustrates an old packet structure. As can be seen in Figure 2A, in IEEE 802.11ac, VHT-SIG-A is replicated in each 20 MHz channel 202. In addition, the VHT-SIG-A transmission uses IEEE 802.11a compatible waveforms containing only 48 data subcarriers.

圖2B例示根據一些實施例之HEW封包結構。本文所揭示之實施例並未在每一片段中複製信號欄位,且替代地在每一20MHz通道202中發射組配接收者站的獨立信號欄位(例如,HEW信號欄位212)。一些實施例可使用五十二(52)個資料副載波(例如,而非48個),從而提供更多副載波以攜帶傳訊資訊。如圖2B中所示,發射傳訊結構200可包含用於多個20MHz通道202中每一者之個別的HEW信號欄位(HEW-SIG-A)212。每一HEW信號欄位212可組配排定HEW站104中一或多者,以用於根據OFDMA技術在20MHz通道202中之一相關聯20MHz通道之一或多個OFDMA子通道上通訊。每一20MHz通道202可為可組配以包括繼HEW信號欄位212之後的一或多個欄位214、216。在一些實施例中,HEW短訓練欄位(HEW-STF)214及資料欄位216可亦包 括於發射傳訊結構200中。以下更詳細地描述此等實施例。 2B illustrates an HEW packet structure in accordance with some embodiments. Embodiments disclosed herein do not duplicate signal fields in each segment, and instead transmit separate signal fields (e.g., HEW signal field 212) that assemble receiver stations in each 20 MHz channel 202. Some embodiments may use fifty-two (52) data subcarriers (eg, instead of 48) to provide more subcarriers to carry messaging information. As shown in FIG. 2B, transmit messaging structure 200 can include individual HEW signal fields (HEW-SIG-A) 212 for each of a plurality of 20 MHz channels 202. Each HEW signal field 212 can be grouped with one or more of the scheduled HEW stations 104 for communicating on one or more OFDMA sub-channels in one of the 20 MHz channels 202 in accordance with OFDMA techniques. Each 20 MHz channel 202 can be configurable to include one or more fields 214, 216 following the HEW signal field 212. In some embodiments, the HEW Short Training Field (HEW-STF) 214 and the Data Field 216 may also be included. Included in the transmit messaging structure 200. These embodiments are described in more detail below.

根據實施例,主站102可經組配以產生封包,該封包包括發射傳訊結構200以組配排定HEW站104,以用於根據OFDMA技術在通道資源上通訊。通道資源可包含舊有20MHz通道202內之一或多個OFDMA子通道。每一OFDMA子通道可包含具有預定頻寬之一或多個最小頻寬單元。 According to an embodiment, the primary station 102 can be assembled to generate a packet that includes a transmit messaging structure 200 to assemble the scheduled HEW station 104 for communicating over channel resources in accordance with OFDMA techniques. The channel resources may include one or more OFDMA subchannels within the old 20 MHz channel 202. Each OFDMA subchannel may include one or more minimum bandwidth units having a predetermined bandwidth.

如先前所論述,HEW OFDMA結構可具有相較於20MHz之較小粒度。因此,用於下行鏈路(DL)或上行鏈路(UL)OFDMA排程之每一HEW信號欄位212可在每一20MHz片段內組配OFDMA結構。以下更詳細地論述此等實施例。 As previously discussed, the HEW OFDMA structure can have a smaller granularity than 20 MHz. Thus, each HEW signal field 212 for a downlink (DL) or uplink (UL) OFDMA schedule can be combined with an OFDMA structure within each 20 MHz segment. These embodiments are discussed in more detail below.

參考圖3及圖4,根據一些實施例,發射傳訊結構20(圖2)可組配排定HEW站104(圖1)以用於根據OFDMA技術在通道資源上通訊,且通道資源可包含20MHz通道202內之一或多個OFDMA子通道302。如圖3及圖4中所示,每一OFDMA子通道302可包含具有預定頻寬之一或多個最小頻寬單元。在此等實施例中,發射傳訊結構可包含用於每 一20MHz通道之獨立信號欄位(例如,HEW信號欄位212(圖2)),以以針對在OFDMA控制週期期間的OFDMA通訊(亦即,下行鏈路通訊或上行鏈路通訊)組配HEW站104。 Referring to Figures 3 and 4, in accordance with some embodiments, a transmit messaging structure 20 (Fig. 2) can be configured to schedule a HEW station 104 (Fig. 1) for communicating over channel resources in accordance with OFDMA techniques, and the channel resources can include 20 MHz. One or more OFDMA sub-channels 302 within channel 202. As shown in FIGS. 3 and 4, each OFDMA subchannel 302 can include one or more minimum bandwidth units having a predetermined bandwidth. In such embodiments, the transmit messaging structure can be included for each An independent signal field of a 20 MHz channel (eg, HEW signal field 212 (FIG. 2)) to group HEW for OFDMA communication (ie, downlink communication or uplink communication) during the OFDMA control period Station 104.

在一些實施例中,每一最小頻寬單元可為例如4.75MHz,且每一OFDMA子通道302可包含多達四個最小頻寬單元,然而實施例之範疇在此方面不受限制。在一些實施例中,每一20MHz通道202可包含多達四個OFDMA子通道302,然而實施例之範疇在此方面不受限制。在此等實施例中,最小頻寬單元之大小固定,而此狀況允許OFDMA子通道302之大小基於最小頻寬單元之數目而變化。 In some embodiments, each minimum bandwidth unit can be, for example, 4.75 MHz, and each OFDMA sub-channel 302 can include up to four minimum bandwidth units, although the scope of the embodiments is not limited in this respect. In some embodiments, each 20 MHz channel 202 can include up to four OFDMA sub-channels 302, although the scope of the embodiments is not limited in this respect. In such embodiments, the size of the minimum bandwidth unit is fixed, and this condition allows the size of the OFDMA subchannel 302 to vary based on the number of minimum bandwidth units.

如以上所提及,可提供用於多個20MHz通道中每一者之個別的HEW信號欄位212(例如,HEW-SIG-A),且每一HEW信號欄位212可組配排定HEW站104中一或多者,以用於根據OFDMA技術在20MHz通道202中之一相關聯20MHz通道之一或多個OFDMA子通道302上通訊。在此等實施例中,每一20MHz通道202上之個別的且可能不同的HEW信號欄位212允許用於每一20MHz通道之OFDMA結構將被單獨組配(例如,不同數目之子通道302、不同通訊參數諸如MCS等)。以下更詳細地論述此等實施例。在一些實施例中,發射傳訊結構200可為前文,然而實施例之範疇在此方面不受限制。 As mentioned above, individual HEW signal fields 212 (eg, HEW-SIG-A) for each of a plurality of 20 MHz channels may be provided, and each HEW signal field 212 may be configured to schedule HEWs One or more of the stations 104 are for communicating on one or more of the OFDMA sub-channels 302 in one of the 20 MHz channels 202 in accordance with OFDMA techniques. In such embodiments, the individual and possibly different HEW signal fields 212 on each 20 MHz channel 202 allow the OFDMA structures for each 20 MHz channel to be individually grouped (eg, a different number of subchannels 302, different Communication parameters such as MCS, etc.). These embodiments are discussed in more detail below. In some embodiments, the transmit messaging structure 200 can be prior, although the scope of the embodiments is not limited in this respect.

在一些實施例中,每一HEW信號欄位212可為20MHz通道202中之一相關聯20MHz通道上的20MHz發射,且個別的HEW信號欄位212中每一者可經組配以在20MHz 通道202中之一相關聯20MHz通道上並行發射。因此,不同HEW信號欄位212可在每一20MHz通道上並行發射。 In some embodiments, each HEW signal field 212 can be a 20 MHz transmission on one of the 20 MHz channels 202 associated with the 20 MHz channel, and each of the individual HEW signal fields 212 can be assembled to be at 20 MHz. One of the channels 202 is transmitted in parallel on an associated 20 MHz channel. Thus, different HEW signal fields 212 can be transmitted in parallel on each 20 MHz channel.

在一些實施例中,每一HEW信號欄位212經配置以組配排定HEW站104,以用於在20MHz通道202中每一20MHz通道內的OFDMA子通道302中多達四個上通訊。在此等示例性實施例中,每一20MHz通道202可分為最多四個最小頻寬單元,每一最小頻寬單元與OFDMA子通道302相關聯。 In some embodiments, each HEW signal field 212 is configured to assemble a scheduled HEW station 104 for up to four up communications in the OFDMA subchannel 302 within each 20 MHz channel in the 20 MHz channel 202. In these exemplary embodiments, each 20 MHz channel 202 can be divided into up to four minimum bandwidth units, each associated with the OFDMA subchannel 302.

在一些實施例中,每一OFDMA子通道302可包含每一20MHz通道內之預定頻寬之介於一個與四個之間的最小頻寬單元。在此等實施例中,因為最小頻寬單元具有預定頻寬,所以20MHz通道內之最小頻寬單元之數目將亦固定。然而,20MHz通道202內之OFDMA子通道302之數目可變化,因為每一OFDMA子通道302可組配為具有若干最小頻寬單元(例如,介於一個與四個之間)。 In some embodiments, each OFDMA subchannel 302 can include a minimum bandwidth unit between one and four of a predetermined bandwidth within each 20 MHz channel. In such embodiments, since the minimum bandwidth unit has a predetermined bandwidth, the number of minimum bandwidth units within the 20 MHz channel will also be fixed. However, the number of OFDMA sub-channels 302 within the 20 MHz channel 202 can vary, as each OFDMA sub-channel 302 can be configured to have a number of minimum bandwidth units (eg, between one and four).

在一些實施例中,最小頻寬單元之預定頻寬為4.375MHz。在一些實施例中,預定頻寬由副載波之預定數目及預定副載波間隔定義。在一些實施例中,副載波之預定數目為十四(14),且預定副載波間隔為312.5KHz以提供4.375之預定頻寬。在此等實施例中,可使用64點FFT。 In some embodiments, the predetermined bandwidth of the minimum bandwidth unit is 4.375 MHz. In some embodiments, the predetermined bandwidth is defined by a predetermined number of subcarriers and a predetermined subcarrier spacing. In some embodiments, the predetermined number of subcarriers is fourteen (14) and the predetermined subcarrier spacing is 312.5 KHz to provide a predetermined bandwidth of 4.375. In these embodiments, a 64 point FFT can be used.

在一些其他實施例中,可使用256點FFT。在使用256點FFT的此等其他實施例中,例如,最小頻寬單元之副載波之預定數目可為14x4=56,且預定副載波間隔可為312.5/4=78.125kHz。 In some other embodiments, a 256 point FFT can be used. In such other embodiments using a 256 point FFT, for example, the predetermined number of subcarriers of the minimum bandwidth unit may be 14x4 = 56, and the predetermined subcarrier spacing may be 312.5 / 4 = 78.125 kHz.

在其他實施例(未分開例示)中,每一HEW信號欄位212可組配排定HEW站104(例如,攜帶用於排定HEW站104之組態),以用於在20MHz通道202中每一20MHz通道內的OFDMA子通道中多達八個或更多個上通訊。在此等其他實施例中,例如,每一20MHz通道202可分為多達八個或更多個最小頻寬單元,且每一最小頻寬單元可小於4.375MHz。 In other embodiments (not separately illustrated), each HEW signal field 212 may be configured to schedule a HEW station 104 (eg, carrying a configuration for scheduling the HEW station 104) for use in the 20 MHz channel 202. Up to eight or more uplinks in an OFDMA subchannel within each 20 MHz channel. In these other embodiments, for example, each 20 MHz channel 202 can be divided into up to eight or more minimum bandwidth units, and each minimum bandwidth unit can be less than 4.375 MHz.

在一些實施例中,每一20MHz通道之HEW信號欄位212可經產生以包括用以指示相關聯20MHz通道之子通道組態的指示符。子通道組態可包括最小頻寬單元之至少一數目。子通道組態可亦包括用於在OFDMA控制週期期間於OFDMA子通道302內通訊的資訊(例如,通訊參數),該資訊包括例如調變及編碼方案(MCS)指示符以及最小頻寬單元之長度指示符。因此,不同通訊參數(例如,MCS)可用於每一20MHz通道202,且在一些實施例中,可用於每一OFDMA子通道302。 In some embodiments, the HEW signal field 212 of each 20 MHz channel can be generated to include an indicator to indicate the subchannel configuration of the associated 20 MHz channel. The subchannel configuration can include at least a number of minimum bandwidth units. The sub-channel configuration may also include information (e.g., communication parameters) for communicating within the OFDMA sub-channel 302 during the OFDMA control period, including, for example, a modulation and coding scheme (MCS) indicator and a minimum bandwidth unit. Length indicator. Thus, different communication parameters (e.g., MCS) are available for each 20 MHz channel 202, and in some embodiments, for each OFDMA sub-channel 302.

在一些實施例中,HEW信號欄位212中用以指示每一20MHz通道之子通道組態的指示符可指示多個子通道組態(例如,子通道組態312A、312B、312C、312D、312E及213F)之一。在圖3及圖4中所例示之實例中,子通道組態312A可包含四個OFDMA子通道302,其中每一OFDMA子通道302包含單個最小頻寬單元。子通道組態312B/C/D可包含三個OFDMA子通道302,其中OFDMA子通道302中兩者包含單個最小頻寬單元且OFDMA子通道302中一者包含兩個 鄰接最小頻寬單元。子通道組態312E可包含兩個OFDMA子通道302,其中每一OFDMA子通道302包含兩個鄰接最小頻寬單元。子通道組態312F可包含單個OFDMA子通道302,該單個OFDMA子通道包含四個鄰接最小頻寬單元。 In some embodiments, an indicator in the HEW signal field 212 to indicate a subchannel configuration for each 20 MHz channel may indicate a plurality of subchannel configurations (eg, subchannel configurations 312A, 312B, 312C, 312D, 312E and One of 213F). In the example illustrated in Figures 3 and 4, subchannel configuration 312A can include four OFDMA subchannels 302, with each OFDMA subchannel 302 containing a single minimum bandwidth unit. The sub-channel configuration 312B/C/D may include three OFDMA sub-channels 302, where both OFDMA sub-channels 302 contain a single minimum bandwidth unit and one of the OFDMA sub-channels 302 contains two Adjacent to the minimum bandwidth unit. Subchannel configuration 312E may include two OFDMA subchannels 302, where each OFDMA subchannel 302 includes two contiguous minimum bandwidth units. Subchannel configuration 312F may include a single OFDMA subchannel 302 that includes four contiguous minimum bandwidth units.

例如,HEW信號欄位212可指示MCS #_1在子通道組態312E之10MHz子通道302中之使用。在一些實施例中,指示符可指示可定義通道202內之不同子通道302之位置及數目的特定子通道組態(亦即,子通道組態312B、子通道組態312C或子通道組態312D)。如圖3中所例示,例如,每一20MHz通道202可根據多個子通道組態中任一子通道組態(例如,子通道組態312A、子通道組態312B、子通道組態312C、子通道組態312D、子通道組態312E或子通道組態312F)加以組配。 For example, HEW signal field 212 may indicate the use of MCS #_1 in the 10 MHz sub-channel 302 of sub-channel configuration 312E. In some embodiments, the indicator may indicate a particular sub-channel configuration that may define the location and number of different sub-channels 302 within the channel 202 (ie, sub-channel configuration 312B, sub-channel configuration 312C, or sub-channel configuration) 312D). As illustrated in FIG. 3, for example, each 20 MHz channel 202 can be configured according to any of a plurality of subchannel configurations (eg, subchannel configuration 312A, subchannel configuration 312B, subchannel configuration 312C, sub Channel configuration 312D, subchannel configuration 312E or subchannel configuration 312F) are combined.

在一些實施例中,20MHz通道之多達52個副載波(亦即,而非習知VHT-SIG-A 211(圖2A)中之48個)可在OFDMA控制週期期間用於根據OFDMA技術的資料通訊。以下更詳細地論述此等實施例。 In some embodiments, up to 52 subcarriers of a 20 MHz channel (ie, instead of 48 of the conventional VHT-SIG-A 211 (FIG. 2A)) may be used during OFDMA control periods according to OFDMA techniques. Data communication. These embodiments are discussed in more detail below.

在一些實施例中,每一20MHz通道202可為可組配以包括繼HEW信號欄位212之後的一或多個欄位214、216。在一些實施例中,更多欄位214、216之一可為可組配以包括最少四個4.375MHz之最小頻寬單元,其等除了DC處之零副載波之外,以零副載波交插,且進一步經組配成包括在DC周圍及在頻帶邊緣處之一或多附加/額外零副載波,以覆蓋每一20MHz通道之20MHz頻寬。例如,對於資 料欄位216,當最小頻寬單元之副載波之預定數目為十四且預定副載波間隔為312.5KHz以供應4.375之預定頻寬時,最小頻寬單元之56個副載波可包括至少一引導副載波,從而允許用於資料之多達52個總副載波,然而實施例之範疇在此方面不受限制。另一方面,HEW-SIG 212將例如使用全部20MHz頻寬來發射,該20MHz頻寬使用例如52個資料單音及4個引導單音。 In some embodiments, each 20 MHz channel 202 can be configurable to include one or more fields 214, 216 following the HEW signal field 212. In some embodiments, one of the more fields 214, 216 can be a minimum bandwidth unit that can be combined to include a minimum of four 4.375 MHz, etc., with zero subcarriers other than the zero subcarrier at the DC. Inserted, and further assembled to include one or more additional/extra zero subcarriers around the DC and at the edge of the band to cover the 20 MHz bandwidth of each 20 MHz channel. For example, for capital In the material field 216, when the predetermined number of subcarriers of the minimum bandwidth unit is fourteen and the predetermined subcarrier spacing is 312.5 kHz to supply a predetermined bandwidth of 4.375, the 56 subcarriers of the minimum bandwidth unit may include at least one guide. The subcarriers allow for up to 52 total subcarriers for the data, although the scope of the embodiments is not limited in this respect. On the other hand, the HEW-SIG 212 will transmit, for example, using a full 20 MHz bandwidth using, for example, 52 data tones and 4 pilot tones.

在一些實施例中,發射傳訊結構200可包括HEW排程(SCH)欄位以指示用於每一排定站104之OFDMA子通道302之特定時間及頻率資源,以用於在OFDMA控制週期期間根據OFDMA技術與主站102通訊。在一些實施例中,HEW排定欄位可具有獨立編碼(亦即,可為個別的欄位),且可在HEW信號欄位212之後,然而此並非必要條件。在其他實施例中,HEW排定欄位可為HEW信號欄位212之部分。在一些實施例中,排程資訊可為HEW信號欄位212而非個別的HEW排定欄位之部分,然而實施例之範疇在此方面不受限制。在一些實施例中,排程資訊可嵌入資料欄位中,然而實施例之範疇在此方面不受限制。 In some embodiments, transmit messaging structure 200 can include a HEW Scheduling (SCH) field to indicate specific time and frequency resources for OFDMA subchannel 302 for each scheduled station 104 for use during an OFDMA control cycle Communication with the primary station 102 is in accordance with OFDMA techniques. In some embodiments, the HEW scheduling field may have an independent encoding (ie, may be an individual field) and may be after the HEW signal field 212, although this is not a requirement. In other embodiments, the HEW scheduling field can be part of the HEW signal field 212. In some embodiments, the schedule information may be part of the HEW signal field 212 rather than an individual HEW scheduled field, although the scope of the embodiments is not limited in this respect. In some embodiments, the schedule information can be embedded in the data field, although the scope of the embodiments is not limited in this respect.

在一些實施例中,主站102可基於用於在OFDMA控制週期期間與主站102通訊的最小頻寬單元來將頻寬分配給排定HEW站104,在該OFDMA控制週期期間,主站102具有無線媒體之專用控制(亦即,在TXOP期間)。在此等實施例中,最小頻寬單元可為可組配以在資料欄位216(圖2)期間經時間及頻率多工化,此舉可在OFDMA控制週期內發 生。在控制週期期間,封包係使用OFDMA根據上行鏈路分空間多重存取(SDMA)技術自排定HEW站104接收,或使用OFDMA根據下行鏈路多工技術發射至排定HEW站104(亦即,資料欄位216(圖2)期間的上行鏈路資料或下行鏈路資料可與排定HEW站通訊)。 In some embodiments, the primary station 102 can allocate bandwidth to the scheduled HEW station 104 based on a minimum bandwidth unit for communicating with the primary station 102 during an OFDMA control period during which the primary station 102 Has dedicated control of the wireless medium (ie, during the TXOP). In such embodiments, the minimum bandwidth unit can be configurable to time and frequency multiplex during data field 216 (FIG. 2), which can be sent during the OFDMA control cycle. Health. During the control period, the packet is received from the scheduled HEW station 104 using OFDMA according to the uplink sub-space multiple access (SDMA) technique, or transmitted to the scheduled HEW station 104 using the OFDMA according to the downlink multiplex technique (ie, The uplink data or downlink data during the data field 216 (Fig. 2) can communicate with the scheduled HEW station).

在一些實施例中,資料欄位216可經組配以用於下行鏈路發射及上行鏈路發射兩者。在此等實施例中,HEW SIG 212或SCH欄位中之排程資訊可包括下行鏈路排程資訊及上行鏈路排程資訊。在此等實施例中,在資料欄位216中之藉由主站102的下行鏈路發射之後,主站102可在特定框間間隔(例如,SIFS)之後於資料欄位216內自排定站接收上行鏈路發射。 In some embodiments, the data field 216 can be configured for both downlink transmissions and uplink transmissions. In such embodiments, the scheduling information in the HEW SIG 212 or SCH field may include downlink scheduling information and uplink scheduling information. In such embodiments, after the downlink transmission by the primary station 102 in the data field 216, the primary station 102 may self-schedule within the data field 216 after a particular inter-frame interval (eg, SIFS). The station receives the uplink transmission.

在一些實施例中,HEW信號欄位212亦可包括組態參數,諸如用以指示是否使用時空區塊編碼(STBC)的STBC(1個位元)指示符、用以允許接收器判定資料酬載為單使用者(SU)或多使用者(MU)的群組ID(6個位元)指示符、用以指示時空串流之數目的時空串流數目(例如,3個位元)指示符、用於LDPC編碼之LDPC附加符號(例如,1個位元)指示符、含有用於酬載之MCS索引值的MCS欄位、用以指示何時將成束矩陣施加於發射的成束(例如,1個位元)指示符、用以允許HEW信號欄位212中之偵測錯誤的循環冗餘檢查(CRC)。此不同於需要頻寬指示符的習知VHT-SIG-A 211(圖2A)。在此等實施例中,HEW信號欄位212將不需要頻寬指示符,因為HEW信號欄位212並非如VHT-SIG-A 211 一般在每一20MHz通道上複製,然而實施例之範疇在此方面不受限制,因為可包括頻寬指示符以接收器實行變得容易。 In some embodiments, the HEW signal field 212 may also include configuration parameters, such as an STBC (1 bit) indicator to indicate whether Space Time Block Coding (STBC) is used, to allow the receiver to determine the data reward. A group ID (6 bit) indicator loaded as a single user (SU) or multiple users (MU), indicating a number of spatiotemporal streams (for example, 3 bits) indicating the number of spatiotemporal streams , an LDPC additional symbol (eg, 1 bit) indicator for LDPC encoding, an MCS field containing the MCS index value for the payload, and a bundle to indicate when the beaming matrix is applied to the transmission ( For example, a 1 bit) indicator, a Cyclic Redundancy Check (CRC) to allow detection errors in the HEW signal field 212. This is different from the conventional VHT-SIG-A 211 (Fig. 2A) which requires a bandwidth indicator. In such embodiments, the HEW signal field 212 will not require a bandwidth indicator because the HEW signal field 212 is not as VHT-SIG-A 211 Typically replicated on every 20 MHz channel, however the scope of the embodiments is not limited in this respect, as the bandwidth indicator can be included to facilitate implementation by the receiver.

在一些實施例中,此等組態參數可用於每一不同子通道組態312A至312F。此可導致與VHT-SIG-A 211相比的較長HEW信號欄位212(例如,6個OFDMA符號或8個OFDMA符號)。 In some embodiments, such configuration parameters are available for each of the different sub-channel configurations 312A through 312F. This may result in a longer HEW signal field 212 (eg, 6 OFDMA symbols or 8 OFDMA symbols) compared to VHT-SIG-A 211.

在一些替代實施例中,相同組態參數中一或多個可與所有組態(亦即,子通道組態312A至312F)(例如,相同STBC或LDPC之使用)交叉排程,以降低HEW信號欄位212之管理負擔。例如,若相同STBC將用於所有子通道組態,則STBC位元無需針對每一子通道組態重複,而是將針對所有最小頻寬單元發送僅一次(例如,在主同步發射中)。此可允許HEW信號欄位212與習知VHT-SIG-A 211相比為較短的。 In some alternative embodiments, one or more of the same configuration parameters may be cross-routed with all configurations (ie, sub-channel configurations 312A through 312F) (eg, the same STBC or LDPC use) to reduce HEW The management burden of the signal field 212. For example, if the same STBC will be used for all sub-channel configurations, the STBC bit does not need to be configured for each sub-channel, but will be sent only once for all minimum bandwidth units (eg, in the primary sync transmission). This may allow the HEW signal field 212 to be shorter compared to the conventional VHT-SIG-A 211.

如以上所論述,在一些實施例中,HEW發射傳訊結構200之更多欄位之一可為可組配以包括與零副載波(亦即,除DC處之零副載波之外)交插的若干最小頻寬單元,且可包括在DC周圍及在頻帶邊緣處之一或多個附加/額外零副載波,以覆蓋每一20MHz通道之20MHz頻寬。在一些實施例中,零副載波之添加可緩和對同步化、DC取消、功率放大器及濾波之實行要求。 As discussed above, in some embodiments, one of the more fields of the HEW transmit messaging structure 200 can be configurable to include interleaving with zero subcarriers (ie, other than the zero subcarriers at the DC). A number of minimum bandwidth units, and may include one or more additional/extra zero subcarriers around the DC and at the edge of the band to cover the 20 MHz bandwidth of each 20 MHz channel. In some embodiments, the addition of zero subcarriers can alleviate the implementation requirements for synchronization, DC cancellation, power amplifiers, and filtering.

在一些實施例中,20MHz通道202可經組配為具有兩個較寬子通道,且每一子通道包含2x4.375MHz最小頻 寬單元之頻寬。在此等實施例中,在每一2x4.375MHz頻寬中發射的波形可與在每一單個4.375MHz最小頻寬單元中發射的所發射兩個波形不同。 In some embodiments, the 20 MHz channel 202 can be configured to have two wider subchannels, and each subchannel includes a 2x 4.375 MHz minimum frequency. The bandwidth of the wide unit. In such embodiments, the waveforms transmitted in each 2x4.375 MHz bandwidth may be different than the transmitted two waveforms transmitted in each individual 4.375 MHz minimum bandwidth unit.

一些實施例可藉由僅允許OFDMA組態之子集(例如,圖4之子通道組態,而非圖3之子通道組態)來簡化設計。此簡化減少組配接收器所需要的資訊,且藉此減少傳訊管理負擔且因此改良整體系統效能。 Some embodiments may simplify the design by allowing only a subset of the OFDMA configuration (eg, the subchannel configuration of Figure 4, rather than the subchannel configuration of Figure 3). This simplification reduces the information required to assemble the receiver and thereby reduces the burden of communication management and thus improves overall system performance.

一些實施例可限制在每一最小頻寬單元中所指派(例如,指派給四個多使用者MIMO(MU-MIMO)使用者)的排定HEW站104之數目。此等實施例可允許空間串流之數目減少至每使用者達三個串流。使MU-MIMO使用者之數目限制於四可使用將要攜帶的僅兩個資訊位元,且使空間串流之數目限制於達三個使用另外兩個資訊位元。此等限制可進一步減少HEW信號欄位212中之傳訊管理負擔,然而實施例之範疇在此方面不受限制。 Some embodiments may limit the number of scheduled HEW stations 104 assigned (e.g., assigned to four multi-user MIMO (MU-MIMO) users) in each minimum bandwidth unit. These embodiments may allow the number of spatial streams to be reduced to three streams per user. Limiting the number of MU-MIMO users to four can use only two information bits to be carried, and the number of spatial streams is limited to three using the other two information bits. These limitations may further reduce the communication management burden in the HEW signal field 212, although the scope of the embodiments is not limited in this respect.
