C實施方式；J 圖式之詳細說明 依據本發明之實施例在多載波環境中清楚定義有效 MAC操作將有利於無線通訊網路中的較佳性能。依據本發 明之實施例由針對次要載波(secondary carrier)的指配與啟 動/止動之發送訊息定義以及由有關行動站台（MS)電力節 省及多載波處理的最佳化指令可獲得類似的性能提升。 本發明的實施例應對多載波的管理：如何分配它們、 如何啟動它們、等等。次要載波的分配往往是一個動態過 201127103 程：視此類如使用者需要的通道條件及服務品質（Q〇S)之因 素而定，更多載波可被加入並接著在不再需要它們時被移 除。疋否需要它們視許多因素而定，該等因素包括MS能 力，例如可接收多少載波、可傳輪多少載波等。 多載波類型及操作模式 在一實施例中，自一MS的角度而言，於一多載波操作 模式中涉及的載波為兩種類型當令之一者：主要載波 (primary carrier)與次要載波。一主要載波是一被一基地台 (BS)用來與一 MS交換訊務流量及實體層（pHY)/MAC控制 發送信號(例如’ MAC管理訊息）之載波。一基地台可被部 署有多個載波但BS中的每一 MS僅有一主要載波（其在當 MS於單一載波模式中操作時也被使用）。次要載波是ms可 用於訊務流量但僅依據主要載波上所接收之BS的特定命令 及規則來使用的額外載波。在多載波操作中，一普通1^八(：: 可利用在一或一個以上次要載波中的無線電資源同時透過 主要載波來保持對MS行動性、狀態及脈絡的完全控制。 在本發明的某些實施例中，主與次要載波都能夠支援 使用者訊務流量與控制資訊二者但主要載波充當次要載波 的一錨點。因此，除了次要載波僅攜載使用者訊務流量的 模式外’次要載波也可在模式中操作，其中它們攜載它們 自己帶内發送信號控制資訊中的一些，諸如，舉例而言， 混合自動重傳請求(HARQ)及通道品質（CQI)回饋、時序提 前與功率控制。同時，諸如交遞、傳呼、安全、行動性、 MS狀態管理等等之更強健的發送信號將典型（至少在某些 201127103 實施例中）被主要載波處理。 如一範例，在某些實施例中，次要載波被用於擴充系 統頻寬以便將一更高的資料率提供給使用者，因而它包括 使用者的額外流量通道以及維持這些通道的一些帶内發送 信號。在一些情況中，這些帶内信號鏈接中的一些，例如 一些回饋，也可在次要載波上被傳輸。如果資料在次要載 波上被接收則回饋可不在相同載波上被發送。代之，陳述 資料在主要載波與次要載波上被接收之回饋可在主要載波 上被發送。換言之，在此類實施例中回饋將不在主與次要 載波上被發送。主要載波將輸送一單一回饋信號，指示資 料是在主要載波、次要載波抑或此兩者上被接收。 在至少某些實施例中，主要載波負責管理MS。舉例而 言，主要載波指示MS進入休眠、進入閒置、執行一交遞操 作等等。主要載波也可啟動額外的次要載波，藉此擴充有 效頻寬。因而人們能在多個載波上進行資源分配及有多個 載波上的資源。換言之，在這些實施例中次要載波可在主 要載波的指示下被動態啟用或停用；與主要載波的一連接 始終被維持。 根據主要及/或次要使用與目標服務，一多載波系統的 載波可如下被不同地組配： 鲁被完全組配載波：一獨立載波，針對此獨立載波所 有包括同步、廣播、多點傳送、及單點傳播控制傳 送信號之控制通道被組配。一被完全組配載波支援 單一載波MS與多載波MS。 201127103 鲁被部分組配載波：一針對TDD中僅下行鏈路傳輸被 組配之載波或一在FDD模式中沒有配對的上行鏈 路(UL)載波之下行鏈路載波。此類補充載波只有結 合一主要載波時才可被使用且無法獨立操作來為 一MS提供IEEE 802.16m服務。一載波是被完全組配 或部分組配可利用載波的高階前文（advanced preamble)來指示。在至少一實施例中，MS將不嘗 試網路登入或交遞給一部分組配的載波。 一主要載波被完全組配而一次要載波視部署情形而定 可被完全或部分組配。一 MS的一次要載波，若被完全組 配，可充當其它MS的主要載波。多個各有一不同的主要RF 載波之MS也可共享相同的次要載波。 考慮一實施例，其中所有的載波被完全組配，亦即， 其中每一載波自我包含，且能夠攜載其自身的發送信號。 如果一BS有兩載波’載波1與載波2，一第一使用者可使用 載波1作為其主要載波而載波2作為其次要載波。一第二使 用者可使用載波2作為其主要載波而載波1作為其次要載 波。如果該第一使用者需要額外的頻寬，則載波丨與載波2 皆可獻給該第一使用者’在此情況中載波1仍為主要載波而 載波2是一借出資源以便增加第一使用者的資料速率之載 波。再者，在此實施例中’每一使用者的主要载波是使用 者一直返回來且用於任一種類廣播監測、傳呼等等之載 波。次要載波僅在當使用者在連接模式中處於需交換超出 MS與主要載波所交換之流量的額外流量之流量狀態時才 201127103 被使用。 下列多載波操作模式被識別，它們可被全部或獨立支 援： 籲多載波聚集：一多載波模式，其中MS維持其實體 層連接並監測主要載波上的控制發送信號同時處 理次要載波上的資料。一MS的資源分配可橫跨一 主要與多個次要RF載波。鏈接適應回饋機制應該包 含相關於主與次要載波的量測。在此模式中，系統 可根據系統負荷（亦即，靜態/動態負荷平衡）、峰值 資料率、或QoS要求在下行鏈路及/或上行鏈路中將 次要載波不對稱地分配給一MS。聚集指同時接收 一主要載波及進而一次要載波（在不中斷接收主要 載波的情況下）。此模式可要求MS具有多個接收 機。這被稱為聚集是因為流量橫越多個載波而實體 上聚集。如果每一載波具有一頻寬20 MHz，舉例而 言，聚集之後的有效頻寬將是約40 MHz。 *多載波切換：一多載波模式，其中MS由BS指令將 其實體層連接自主要載波切換至次要載波。MS在 一特定時段(BS知曉的一時段）與次要載波連接及 進而返回與主要載波連接。當MS被連接至次要載 波時，MS不需要維持其與主要載波的實體層連 接。此模式可在廣播/多點傳送或其它單點傳播服務 中被使用以切換至僅下行鏈路傳輸服務的被部分 組配載波。如一範例，若要發送一大檔案但期望避 [s 3 9 201127103 免有目前載波上的流量限制頻寬的話，可作出一到 一不同載波的切換，及被提供用以完成下載的指令 進而在（比方說）1〇毫秒内返回至主要載波。BS知曉 另一載波在這10毫米正被使用，及MS知曉在這10 毫秒内作什麽。 籲主要載波改變· 一多載波模式，其中BS改變一 MS 的主要载波。此模式類似於一快速載波間交遞，其 中僅PHY改變而維持MS控制在相同MAC上。此多 載波模式被所有MS需要。主要載波改變模式可涉 及在沒有進行一完全網路層級交遞的情況下主要 載波自載波1被改變至載波2。在此情況中，改變相 對基地台而言是局部的而非在網路層級被處理，因 為該改變僅是自一射頻至另一射頻的改變。完全控 制自一載波行進至另一載波。從一上層的視角而 言，改變是一斷開。從一下層的視角而言，改變沿 著自一 10 MHz通道改變至一20 MHz通道或自一20 MHz通道改變至另一20 MHz通道的線。 在操作的所有多載波模式中下列内容都是共同的： 系統定義N個獨立被完全組配Rp載波；每一個用全 部同步、廣播、多點傳送及單點傳播控制發送信號 通道被完全組配。細胞中的每一 MS被連接至主要 栽波且其狀態透過被完全組配載波當中之謹一被 標示為主要載波之載波控制。 系統也定義M(M > 0)個被部分組配的載波，它們僅 ⑧ 10 201127103 可隨一主要載波一起被用作次要載波供僅下行鏈 路資料傳輸。 參一 BS中所有支援的無線電載波之集合被稱為可用 載波。 鲁多個載波可以在相同頻譜區塊的不同部分或在非 相鄰的頻譜區塊。支援非相鄰的頻譜區塊可需要次 要載波上的額外控制資訊。 *除了（服務）主要載波之資訊之外，一支援任一多載 波模式之BS透過此主要載波亦向MS提供其它可用 載波的一些基本資訊。基本多載波組態告知MS所 有可用載波的存在、頻寬、雙工、及頻譜中的位置 以助MS備於作任一多載波操作。主要載波也可向 一 MS提供關於次要載波組態之延伸資訊。 MAC操作 多載波的MAC操作與單一載波模式的MAC操作相 同，及除非在下面另有說明的外，發送訊息被攜載於每一 MS的主要載波上。 網路登入 多載波模式中的網路登入與單一載波模式中的網路登 入相同，其中MS與BS在能力協商期間也指示它們對多載波 模式的支援。一MS可僅用一被完全組配載波執行網路登入 (或網路重入)程序。一旦MS檢測到一被完全組配載波上的 一前文，MS可繼續進行讀取超框標頭（SFH)或延伸的系統 參數與系統組態資訊。 11 201127103 在初始網路登入期間，MS將透過REG-REQ訊息告知 BS其對多載波傳輸的支援，及BS將透過REG_RSP訊息指示 是否其支援該MS的任何多載波模式。基本多載波能力交換 利用REG-REQ/RSP訊息中的一個兩位元碼，其中有下列指 示：

被接收（170)。MS與BS接著備於多載波操作（180)。 MS獲得可用載波的MC組態 雖然有關一服務載波之無線電組態的資訊在S F Η上被 傳送’但是在至少一實施例中BS將透過MC-ADV訊息向MS 提供BS中其它可用載波的基本無線電組態。此訊息由BS週 期性地傳送’其包括多載波模式及BS支援的組態。多載波 組態資訊相關於所有MS且可被所有MS用於任一多載波模 式或單一載波模式。在可用載波的資訊於整個網路中相同 的情況下，作為配置的部分，網路可向厘8提供初始網路登 入的資訊，且MS可儲存及應用此資訊直至網路提供一更 新。 MC—CONG—ADV(多載波組態廣告)訊息：在至少一實 施例中B S週期性傳送MC—ADV訊息供所有接收 。若不同 於服務載波，此訊息包括諸如中心頻率、雙工模式、頻寬、 及其匕參數之資訊，及它也向每_載波指配—實體載波索

獲付關於指配載波的貧訊 在能力協商之後，且如果BS確定了一MS之多載波特徵 的可用性的話，MS可透過一MC-REQ(多載波請求）訊息請 求BS獲得關於指配載波的資訊。指配載波是可用載波的子 集，該等可用載波可能被B S在此M S的任一後續多載波操作 中使用。MS透過MC-RSP(多載波響應)訊息響應於MS的請 求。 MC-REQ(多載波請求）：多載波請求訊息是由MS發送

DETAILED DESCRIPTION OF THE DRAWINGS The clear definition of effective MAC operation in a multi-carrier environment in accordance with embodiments of the present invention will facilitate better performance in a wireless communication network. Embodiments in accordance with the present invention can be similarly derived from the assignment of the assignment and stop/stop for the secondary carrier and the optimization instructions for the mobile station (MS) power save and multi-carrier processing. Performance improvement. Embodiments of the invention should address the management of multiple carriers: how to allocate them, how to start them, and the like. The allocation of secondary carriers is often a dynamic one. The process depends on the channel conditions and quality of service (Q〇S) required by the user. More carriers can be added and then when they are no longer needed. Was removed. They are not required to depend on many factors, including MS capabilities, such as how many carriers can be received, how many carriers can be transmitted, and so on. Multi-Carrier Type and Mode of Operation In one embodiment, the carrier involved in a multi-carrier mode of operation is one of two types from the perspective of an MS: primary carrier and secondary carrier. A primary carrier is a carrier used by a base station (BS) to exchange traffic and physical layer (pHY)/MAC control transmission signals (e.g., 'MAC management messages) with an MS. A base station can be deployed with multiple carriers but each MS in the BS has only one primary carrier (which is also used when the MS is operating in a single carrier mode). The secondary carrier is an additional carrier that ms can use for traffic traffic but only based on specific commands and rules of the BS received on the primary carrier. In multi-carrier operation, a normal 1^8 (:: radio resources in one or more secondary carriers can be used to simultaneously maintain full control of MS mobility, state, and context through the primary carrier. In some embodiments, both the primary and secondary carriers are capable of supporting both user traffic and control information but the primary carrier acts as an anchor for the secondary carrier. Therefore, except for the secondary carrier, only the user traffic is carried. Out-of-mode 'secondary carriers' can also operate in modes where they carry some of their own in-band transmit signal control information such as, for example, hybrid automatic repeat request (HARQ) and channel quality (CQI) Feedback, timing advance, and power control. At the same time, more robust transmit signals such as handover, paging, security, mobility, MS state management, etc. will typically be handled (at least in some 201127103 embodiments) by the primary carrier. For example, in some embodiments, the secondary carrier is used to augment the system bandwidth to provide a higher data rate to the user, thus including the user's amount Traffic channels and some in-band transmit signals that maintain these channels. In some cases, some of these in-band signal links, such as some feedback, may also be transmitted on the secondary carrier. If the data is received on the secondary carrier The feedback may then not be sent on the same carrier. Instead, the feedback that the presentation data is received on the primary and secondary carriers may be sent on the primary carrier. In other words, in such embodiments the feedback will not be primary or secondary. The primary carrier will transmit a single feedback signal indicating whether the data is received on the primary carrier, the secondary carrier, or both. In at least some embodiments, the primary carrier is responsible for managing the MS. For example, The primary carrier indicates that the MS enters sleep, enters idle, performs a handover operation, etc. The primary carrier can also activate additional secondary carriers, thereby augmenting the effective bandwidth. Thus, people can allocate resources on multiple carriers and have more Resources on one carrier. In other words, in these embodiments the secondary carrier can be dynamically enabled or disabled under the direction of the primary carrier. A connection to the primary carrier is always maintained. Depending on the primary and/or secondary usage and target service, the carriers of a multi-carrier system can be differently configured as follows: Lu is fully configured carrier: a single carrier, for this The control channels of the independent carrier including the synchronous, broadcast, multicast, and unicast control transmission signals are combined. One fully equipped carrier supports the single carrier MS and the multi-carrier MS. 201127103 Lu is partially matched carrier: one For downlink only transmissions of downlink carriers in TDD or an uplink (UL) carrier downlink carrier that is not paired in FDD mode. Such supplementary carriers can only be used when combined with a primary carrier and It is not possible to operate independently to provide an IEEE 802.16m service for an MS. A carrier is indicated by a high-level advanced preamble that is fully or partially assembled. In at least one embodiment, the MS will not attempt to log in or hand over to a portion of the configured carrier. A primary carrier is fully assembled and a primary carrier may be fully or partially configured depending on the deployment scenario. A primary carrier of an MS, if fully configured, can serve as the primary carrier for other MSs. Multiple MSs each having a different primary RF carrier may also share the same secondary carrier. Consider an embodiment in which all carriers are fully assembled, i.e., each carrier is self-contained and capable of carrying its own transmit signal. If a BS has two carriers 'Carrier 1 and Carrier 2, a first user can use Carrier 1 as its primary carrier and Carrier 2 as its secondary carrier. A second user can use carrier 2 as its primary carrier and carrier 1 as its secondary carrier. If the first user needs additional bandwidth, both carrier 载波 and carrier 2 can be dedicated to the first user. In this case, carrier 1 is still the primary carrier and carrier 2 is a lending resource to increase the first. The carrier of the user's data rate. Furthermore, in this embodiment, the primary carrier of each user is the carrier that the user has been returning all the time and used for any kind of broadcast monitoring, paging, and the like. The secondary carrier is used only when the user is in the connected state to exchange traffic for excess traffic that exceeds the traffic exchanged between the MS and the primary carrier. The following multi-carrier modes of operation are identified, which can be supported fully or independently: Multi-carrier aggregation: A multi-carrier mode in which the MS maintains its physical layer connection and monitors the control transmit signal on the primary carrier while processing the data on the secondary carrier . The resource allocation of an MS can span a primary and multiple secondary RF carriers. The link adaptation feedback mechanism should contain measurements related to the primary and secondary carriers. In this mode, the system can asymmetrically assign secondary carriers to an MS in the downlink and/or uplink based on system load (ie, static/dynamic load balancing), peak data rate, or QoS requirements. . Aggregation refers to receiving a primary carrier and thus a secondary carrier simultaneously (without interrupting the reception of the primary carrier). This mode can require the MS to have multiple receivers. This is called aggregation because traffic converges across multiple carriers and is physically aggregated. If each carrier has a bandwidth of 20 MHz, for example, the effective bandwidth after aggregation will be about 40 MHz. * Multi-Carrier Switching: A multi-carrier mode in which the MS switches its physical layer connection from the primary carrier to the secondary carrier by the BS command. The MS connects to the secondary carrier and then back to the primary carrier for a certain period of time (a period known by the BS). When the MS is connected to the secondary carrier, the MS does not need to maintain its connection to the physical layer of the primary carrier. This mode can be used in broadcast/multicast or other unicast services to switch to a partially-assigned carrier of only the downlink transport service. As an example, if you want to send a large file but you want to avoid [s 3 9 201127103 without the current traffic limit bandwidth on the carrier, you can make one to one different carrier switching, and the instructions provided to complete the download. (say) return to the primary carrier within 1 millisecond. The BS knows that another carrier is being used at this 10 mm, and the MS knows what to do in this 10 millisecond. Calling the primary carrier change · A multi-carrier mode in which the BS changes the primary carrier of an MS. This mode is similar to a fast inter-carrier handover in which only the PHY changes while maintaining the MS control on the same MAC. This multi-carrier mode is required by all MSs. The primary carrier change mode may involve the primary carrier being changed from carrier 1 to carrier 2 without performing a full network level handover. In this case, the change is local to the base station and not processed at the network level because the change is only a change from one radio to another. Full control from one carrier to another. From the perspective of an upper level, the change is a disconnect. From the perspective of the next layer, change the line that changes from one 10 MHz channel to one 20 MHz channel or from one 20 MHz channel to another 20 MHz channel. The following are common in all multi-carrier modes of operation: The system defines N independent fully-fitted Rp carriers; each of which uses all synchronous, broadcast, multicast, and unicast control transmit signal channels to be fully assembled . Each MS in the cell is connected to the primary carrier and its state is controlled by the carrier that is designated as the primary carrier among the fully assembled carriers. The system also defines M(M > 0) partially matched carriers, which are only 8 10 201127103 and can be used as a secondary carrier with a primary carrier for downlink-only data transmission. The set of all supported radio carriers in a participating BS is referred to as an available carrier. Multiple carriers may be in different parts of the same spectral block or in non-adjacent spectral blocks. Supporting non-adjacent spectral blocks may require additional control information on the secondary carrier. * In addition to the (service) primary carrier information, a BS supporting any multi-carrier mode also provides the MS with some basic information about other available carriers through the primary carrier. The basic multi-carrier configuration informs the MS of the presence, bandwidth, duplex, and location of the available carriers to assist the MS in any multi-carrier operation. The primary carrier can also provide an MS with extended information about the secondary carrier configuration. MAC Operation The multi-carrier MAC operation is the same as the MAC operation of the single carrier mode, and unless otherwise stated below, the transmitted message is carried on the primary carrier of each MS. Network Login The network login in multi-carrier mode is the same as the network login in single carrier mode, where the MS and BS also indicate their support for multi-carrier mode during capability negotiation. An MS can perform a network login (or network reentry) procedure using only a fully assembled carrier. Once the MS detects a preamble on a fully assembled carrier, the MS can continue to read the superframe header (SFH) or extended system parameters and system configuration information. 11 201127103 During the initial network login, the MS will inform the BS of its support for multi-carrier transmission through the REG-REQ message, and the BS will indicate through the REG_RSP message whether it supports any multi-carrier mode of the MS. The basic multi-carrier capability exchange utilizes a two-digit code in the REG-REQ/RSP message with the following indications: bl, b2 multi-carrier capability 00 no MC mode 01 multi-carrier aggregation 10 multi-carrier handover 11 multi-carrier aggregation and multi-carrier A procedure for switching a MS, followed by a network login in accordance with an embodiment of the present invention for subsequent multi-carrier operation in accordance with an embodiment of the present invention is illustrated in FIG. This procedure includes: Multi-carrier configuration for obtaining available carriers at the BS * Obtaining information about the assigned carrier consists of the following two steps: L Provides the BS with information on the supportable carriers of the MS and their combined multi-carrier configuration. 2. Obtain the information of the subset of available carriers (referred to herein as assigned carriers) that can be used by the BS for subsequent multi-carrier operation of the MS. The MS does not perform any mac or PHY processing on a assigned carrier unit until the carrier is initiated by the indication of the BS. The network login process (which is the same as the single carrier mode) includes basic multi-carrier capability negotiation during REG-REQ-RSP. Still referring to Figure 1 'a block 110' refers to establishing an assigned connection. A block 120 establishes that such a connection is operational. At block 130, a query is made as to whether the MS and the BS support a shared multi-carrier mode 8 12 201127103 is proposed. If the answer is not supported, the processing continues according to the single carrier procedure (14〇). If the answer is support, and the MC-CONFIG-ADV message has been received (150), the MC-REQ including multi-carrier capability negotiation is sent (160). If the answer is support and the MC-CONHG-ADV message is not received then processing returns to the point just before MC-CONFIG-ADV receives the query. After the MC-REQ transmission, the MC-RSP including a list of assigned carriers is received (170). The MS and BS are then provisioned for multi-carrier operation (180). The MS obtains the MC configuration of the available carriers although information about the radio configuration of a serving carrier is transmitted on the SF ' 'But in at least one embodiment the BS will provide the MS with the basis of other available carriers in the BS via the MC-ADV message. Radio configuration. This message is periodically transmitted by the BS' which includes the configuration of the multi-carrier mode and the BS support. Multi-carrier configuration information is relevant to all MSs and can be used by all MSs in any multi-carrier mode or single carrier mode. In the same situation where the available carrier information is the same throughout the network, as part of the configuration, the network can provide initial network access information to the PCT 8, and the MS can store and apply this information until the network provides an update. MC-CONG-ADV (Multi-Carrier Configuration Advertisement) message: In at least one embodiment, the BS periodically transmits MC-ADV messages for all reception. If different from the service carrier, this message includes information such as center frequency, duplex mode, bandwidth, and its parameters, and it also assigns to each carrier-physical carrier index, which is approved and used. For any reference to any available carrier. This configuration information applies to all Ms. The following parameters can be included in the MC_ADv message 13 201127103 for each available carrier: Call the physical carrier index to call the center frequency (for example, band class index and channel index) Lu channel bandwidth call carrier type (only the old mode, is completely / Partially arbitrarily) * Duplex mode * Main preamble index Lu sub-previous index _ Transmission power The same information for the service carrier can be ignored to reduce the burden. The poor information about the assigned carrier is after capability negotiation, and if the BS determines the availability of the multi-carrier feature of the MS, the MS may request the BS to obtain the assigned carrier through an MC-REQ (Multi-Carrier Request) message. News. The assigned carrier is a subset of the available carriers that may be used by the B S in any subsequent multi-carrier operation of this M S . The MS responds to the MS request through the MC-RSP (Multi-Carrier Response) message. MC-REQ (Multi-Carrier Request): A Multi-Carrier Request message is sent by the MS to the BS to request a list of assigned carriers. In at least one embodiment, this message will include all information about the multi-carrier configuration supported by the MS, which information is needed by the BS to determine which carrier or combination thereof is assigned to the MS and to initiate when needed. The following are the parameters to be included in the MC-REQ message in at least one embodiment of the present invention: 8 14 201127103 Dependent MS Multi-Carrier Capability and Limit Maximum Carrier in Lu DL/UL #Maximum Interval Between Carriers Candidate Assignment The carrier list # supports the data transmission MC-RSP (Multi-Carrier Response) message through the protection sub-carrier: according to the information provided by the ms on the MC-REQ, in at least one embodiment, the BS will respond to the MS to the MS through the MC-RSP message. Provide information about its assigned carrier. In at least one embodiment, the following parameters are to be included in the MC-RSP message: Xin assigned carrier list An additional/detailed MC configuration of the assigned carrier (optional) is supported by the protected secondary carrier The data transmission MC-RSP is typically sent by the BS to the MS in response to the MC-REQ message, but it can also be sent to an MS to update the assigned carrier list. The order in which a carrier appears in an MC-RSP message can be used as a logical carrier index for subsequent reference assignment of carriers. Alternatively, the CC carrier index provided in the MC_CONF__ADV §fl can be used for this addressing. Bandwidth Request and Resource Allocation Use the assigned bandwidth request channel to follow the same procedure as defined for the single carrier mode to transmit all bandwidth requests on the primary carrier of the MS. The bandwidth request using the piggyback mode is transmitted through the (multiple) secondary carrier and the primary carrier in an MPDU consistent with the single carrier mode. When receiving a bandwidth request, the BS may allocate downlink or uplink resources belonging to a specific carrier or a combination of one of 15 201127103 carriers. The carrier-aggregated multi-carrier-Beiyuan assignment can utilize the same AMAP_IE as the single carrier mode where the A-MAP messages of the parent-active carrier are transmitted in the respective carriers. Alternatively, a special multi-carrier octave can be used and transmitted on the primary carrier to allocate resources among the primary and secondary carriers of the same constituent information element. Service settings/change messages (DSX messages) are typically transmitted only through the primary carrier of the MS. The service flow is defined for a common MAC entity and the QoS context of the MS represented by an SFID is applicable to both the primary carrier and the secondary carrier and is applied to all carriers of the MS. DLCINR Reporting Operation A BS can assign a C()I channel to each carrier of an MS. When the 〇()1 channel is assigned, the MS reports the CINR of a carrier through the assigned cq channel of the corresponding carrier. When the REP-REQ/RSP message is used for the dl CINR reporting operation, the message is transmitted on the primary carrier of the MS. The REp_RSp message may contain ciNR reports for each carrier or each carrier of the MS. If the signal quality of the secondary carrier is below a threshold, the MS may be instructed not to transmit the CINR measurement of the secondary carrier, in which case the BS will no longer transmit data on the current carrier until the signal quality is raised to the threshold. Above the value and the MS resumes transmitting CINR measurements on the secondary carrier. Handover Process An MS follows the handover process defined by the single carrier mode. In at least one embodiment, all of the mac management messages associated with the handover (H0) are transmitted over the primary carrier. 8 16 201127103 In the HO preparation phase, when a Bs receives a h〇_REq message from a hall or when the BS sends a HO-CMD message to the ms, the BS can exchange information of multiple carrier capabilities with the possible target BS. . This information includes the number of available carriers of the MS, carrier aggregation or carrier switching capability. When information about an MS identity (eg, a station identifier (STID)) or a security context of a target BS is pre-updated during η Ο preparation, multi-carrier related information (eg, secondary carrier) may utilize one H The 〇_CMD message is provided to the MS. After deciding to handover to a target BS, an MS implements its network re-entry with a selected carrier. The selected carrier becomes the primary carrier of the MS at the target BS. If the primary carrier is not previously provided to the MS, the target BS may assign a secondary carrier during network reentry or the connection may change to a single primary carrier mode. Sleep Mode When an MS enters sleep mode, the MS negotiates its sleep mode parameters with a BS (ie, 'hibernation window and listening window configuration'). The parameters negotiated in sleep mode are applied to an MS& all carriers to down-regulate power based on the negotiated sleep mode parameters. Idle mode MS determines a preset carrier to monitor paging and other transmission control messages in a manner similar to a single carrier mode. This selected carrier is the primary carrier of the MS in idle mode if it is not a BS change. The message and program for initializing the idle mode are handled by the MS's primary carrier. In the paging listening interval, the MS monitors the paging message on its primary carrier that conforms to the single carrier mode. When being paged, the MS performs the 17 201127103 network re-entry procedure with the primary carrier. Secondary carrier management Carrier management involves the exchange of a 1 - 〇 -01 -01 -01 -01 -01 -01 -01 -01 -01 -01 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- 4- These messages enable secondary carrier start and stop, primary carrier change, or primary to secondary handover in multi-carrier aggregation. Secondary carrier management involves starting or stopping the carrier, which causes multi-carrier processing of the MS to start or stop. The start or stop (multiple) secondary carriers are determined by bs based on QoS requirements, carrier load conditions, and other factors and are indicated to the MS via the MCM-DIRMAC management message. The initiation of the secondary carrier in the aggregation mode is MCM-DIR/MCM-CONFIRM exchanged between the MS and the BS. The BS transmits the MCM-DIR MAC management message on the primary carrier and includes the following information: * Carrier index list (logical carrier index) and for each carrier • Type of action: (start or stop) Ludo carrier operation: (aggregation, switching * The retrievable field allocated by the feedback channel of the primary carrier of the MS is used to transmit the channel feedback for starting the secondary carrier. If the carrier is not fully configured, ♦ the combined feedback on the primary carrier (on/off) • Range: STID or stream identifier (FID). If STID MC mode can be applied to any service/connection of the MS.

This message confirms with the BS that MS 8 18 201127103 has successfully started/stopped the carrier listed in the MCM-DIRECT message. It sends a confirmation when the MS is ready to receive an allocation message on the start carrier. After the BS receives the MCM-IND MAC management message, the BS and the single carrier mode' BS can begin transmitting the allocation information and data on this (class) active secondary carrier. The BS may allocate a fast feedback channel for each newly activated secondary carrier on the MC-IND message. The MS can report the CQI of all downlink active secondary carriers. The MS may perform periodic ranging of uplink active secondary carriers. When referred to by the BS as an uplink active secondary carrier, the sound channel can also be transmitted by the MS. The MS can update system information for all active secondary carriers and can monitor resource allocation messages for all active secondary carriers. Figure 2 illustrates the initialization and termination of multi-carrier processing of mS in accordance with an embodiment of the present invention and in conjunction with the foregoing description. The primary carrier change BS may indicate that the MS is load balanced, the changed channel quality of the carrier, or other reason to change one of its primary carriers to one of the available fully assembled carriers within the same BS through the control transmission signal on the current primary carrier. The MS switches to the carrier to which the target is fully configured at a time specified by the BS. ^^ The carrier change can also be requested by the control transmission signal on the current primary carrier. It is assumed that a common MAC management service and a target primary carrier do not require a network re-human procedure of the target primary carrier. The BS can provide the system with information different from the primary carrier of the primary carrier of the service through the primary carrier of the service. When the current STID is ready for another (10) service, the BS can assign a new STID. The logical carrier index can be rearranged. BS can indicate an MS to change

The BS may instruct the MS to perform scanning on other carriers that do not serve the MS. The MS reports the scan result back to the serving BS, and the result can be used by the BS to determine the carrier to which the MS switches. In this case, if the target carrier does not currently serve the MS, the MS can perform synchronization with the target carrier if needed. Carrier Switching Mode Supports primary to secondary carrier switching in multi-carrier mode when primary carriers are partially matched. The carrier switching between a primary carrier and a primary carrier may be periodic or triggered by an event parameter defined by a multicarrier switching message on the primary carrier. When an MS switches to a primary carrier, its primary carrier can provide basic information, such as timing and frequency adjustments, to facilitate fast synchronization of the MS with the secondary carrier.

A step 310 of method 300 is to receive an identification of available carriers at the mobile station. A step 320 of method 300 is to transmit information about the carrier supported by the mobile station and their combined multi-carrier configuration. A step 330 of method 300 is to receive information identifying certain ones of the available carriers that are suitable for use by the mobile station in multi-carrier operation. 4 is a flow chart illustrating a carrier management method 400 utilizing a primary carrier in a wireless communication protocol, the primary 8 20 201127103 carrier capable of carrying a base station and a mobile station in accordance with an embodiment of the present invention.
