Description
本發明與無線通訊有關 The invention relates to wireless communication
無線通訊系統正在持續發展,以便滿足對於提供連續和更快捷資料網路存取的需要。這種演進由這樣一種希望驅動,那就是行動用戶能夠出於商業、休閒或其他目的而在任何時間從任何地點連接到其他用戶或資訊網路。為了滿足這些需要,無線通訊系統可以使用多個載波來傳輸資料。使用多個載波傳輸資料的無線通訊系統可以稱為多載波系統。在蜂窩和非蜂窩無線系統中,多個載波的運用都在擴展。依照多少個載波中的多個載波是可用的,多載波系統可以增加無線通訊系統中的可用頻寬。例如,雙載波系統可以將單載波系統的頻寬加倍,三載波系統可以將單載波系統的頻寬提升到三倍等等。除了流通量增益之外,分集和聯合排程增益同樣是被期待的。這種處理可以為終端用戶提升服務品質(QoS)。更進一步,多個載波的運用可以與多輸入多輸出(MIMO)結合使用。 Wireless communication systems are evolving to meet the need to provide continuous and faster access to data networks. This evolution is driven by the desire that mobile users can connect to other users or information networks from any location, at any time, for business, leisure or other purposes. To meet these needs, wireless communication systems can use multiple carriers to transmit data. A wireless communication system that transmits data using multiple carriers can be referred to as a multi-carrier system. In both cellular and non-cellular wireless systems, the use of multiple carriers is expanding. Depending on how many carriers are available, the multi-carrier system can increase the available bandwidth in the wireless communication system. For example, a dual carrier system can double the bandwidth of a single carrier system, and a three carrier system can triple the bandwidth of a single carrier system. In addition to the throughput gain, diversity and joint scheduling gains are also expected. This processing can improve quality of service (QoS) for end users. Furthermore, the use of multiple carriers can be used in conjunction with Multiple Input Multiple Output (MIMO).
例如在第三代合作夥伴專案(3GPP)系統的語境中,在3GPP規範版本8中引入了被稱為雙胞元高速下鏈封包存取(DC-HSDPA)的全新特徵。在DC-HSDPA中,同一地理區域被至多兩個HSDPA載波所覆蓋,這些載波處於相同波段並有可能相鄰。DC-HSDPA系統中,在相同波段的載波之間使用頻率分集,那麼系統性能將會提升。對DC-HSDPA來說,基地台(在 通訊網路的其他變型或類型中也可將其稱為節點B、存取點、站點控制器等等)同時在兩個下鏈載波上與無線發射/接收單元(WTRU)通訊。這樣做不但會使WTRU可用的頻寬和峰值資料速率加倍,而且還可以用兩個通道上的快速排程和快速通道回饋來提高網路效率。 For example, in the context of the 3rd Generation Partnership Project (3GPP) system, a new feature called Dual High Speed Downlink Packet Access (DC-HSDPA) was introduced in 3GPP Specification Release 8. In DC-HSDPA, the same geographical area is covered by up to two HSDPA carriers, which are in the same band and possibly adjacent. In the DC-HSDPA system, frequency diversity is used between carriers in the same band, and system performance will increase. For DC-HSDPA, the base station Other variants or types of communication networks may also be referred to as Node Bs, access points, site controllers, etc., while communicating with wireless transmit/receive units (WTRUs) on two downlink carriers. Not only does this double the bandwidth and peak data rates available to the WTRU, but it also improves fast network efficiency with fast scheduling and fast channel feedback on both channels.

If more than two carriers are configured, the WTRU may include more than one primary carrier and/or more than one secondary carrier. For example, an anchor carrier can be defined as a carrier that carries a particular set of control information for downlink/uplink transmission. Any carrier that is not assigned as an anchor carrier can be a secondary carrier. Alternatively, the network does not necessarily specify an anchor carrier and may not provide priority, preference or preset status for the downlink or uplink carrier.

First, the sectors are one or more cells that belong to the same base station and cover the same geographic area. Second, the two carriers have the same time reference and their downlinks are synchronized. Next, the term "anchor carrier" refers to a downlink frequency carrier associated with an uplink frequency carrier assigned to the WTRU, and the term "auxiliary carrier" refers to a downlink frequency carrier of a non-anchor carrier.

The plurality of carriers may or may not be adjacent and may or may not be at the same frequency or radio band and/or frequency range. In one embodiment, the plurality of carriers may include, but are not limited to, any one of: four adjacent downlink carriers in the same band and one or two uplink carriers in the same band; Two pairs of two adjacent downlink carriers in two different bands, and two uplink carriers in each of the bands, or three adjacent downlink carriers in the same band, and are also in the same One or two (adjacent) uplink carriers of the band.

When more than one downlink carrier transmits a downlink control channel associated with one or more uplink carriers, the downlink "anchor" carrier may refer to a downlink carrier configured with "anchored" carrier characteristics. Alternatively, the term downlink "anchored" carrier may refer to a downlink carrier that carries a serving HS-DSCH cell. Alternatively, if a single downlink carrier is configured for the WTRU, then the carrier is the primary downlink carrier.
下列註釋自始至終都可以使用。術語DLn和ULn分別指的是第n個次級服務高速下鏈共用通道(HS-DSCH)胞元(次級 DL載波)以及第n個次級服務增強型專用通道(E-DCH)胞元(次級UL載波),其中n>0。術語DL0和UL0分別是指主服務HS-DSCH胞元(主DL載波)和主服務E-DCH胞元(主UL載波)。 The following notes are available from start to finish.

The terms DL0 and UL0 refer to the primary serving HS-DSCH cell (primary DL carrier) and the primary serving E-DCH cell (primary UL carrier), respectively.
在一些實施方式中,UL載波可以與DL載波配對。另一方面,DL載波可以是不成對的(即所配置的DL載波數量可以大於或等於所配置的UL載波數量)。在DL載波與UL載波配對的情況下,UL/DL載波配對有可能需要三個不同的命令來覆蓋載波配對的三種可能狀態之間的轉換,其中狀態1有可能是指UL和DL載波都被啟動,狀態2有可能是指UL和DL載波都被停用,狀態3有可能是指DL載波啟動以及UL載波停用。 In some embodiments, the UL carrier can be paired with a DL carrier. On the other hand, the DL carriers may be unpaired (ie, the number of configured DL carriers may be greater than or equal to the configured number of UL carriers). In the case where the DL carrier is paired with the UL carrier, the UL/DL carrier pairing may require three different commands to cover the transition between the three possible states of the carrier pairing, where state 1 may refer to both the UL and DL carriers being Startup, state 2 may mean that both UL and DL carriers are disabled, state 3 may refer to DL carrier initiation and UL carrier deactivation.
在替代實施方式中,如果停用了相關聯的DL載波,則UL載波未必是啟動的。 In an alternate embodiment, the UL carrier is not necessarily enabled if the associated DL carrier is deactivated.
在DL載波不成對(即DL載波沒有相關聯的UL載波)的情況下,需要兩個不同命令來覆蓋兩種可能狀態之間的轉換,其中狀態1有可能是指DL載波啟動,狀態2則有可能是指DL載波停用。 In the case where the DL carriers are unpaired (ie, the DL carrier has no associated UL carrier), two different commands are needed to cover the transition between the two possible states, where state 1 may refer to DL carrier initiation, state 2 It may be that the DL carrier is deactivated.

In an alternate example, the HS-SCCH order may be reserved for use in starting and deactivating all of the supplementary carriers simultaneously.
HS-SCCH命令的信號傳遞可以使用標記為xodt,1,xodt,2,xodt,3的命令類型位元以及標記為xord,1,xord,2,xord,3的命令位元來執行。 The HS-SCCH command signal passing can use the command type bits marked x odt,1 ,x odt,2 ,x odt,3 and the command bits marked x ord,1 ,x ord,2 ,x ord,3 Yuan to implement.
在第一實施方式中,命令類型指示的是啟動/停用命令,命令位元指示的則是該命令所應用的載波。例如,如果命令類型xodt,1,xodt,2,xodt,3=‘010’,那麼該命令是用於由xord,1,xord,2,xord,3指示的輔助載波索引的啟動命令。如果命令類型xodt,1,xodt,2,xodt,3=‘011’,那麼該命令是用於由xord,1,xord,2,xord,3指示的輔助載波索引的停用命令。其他輔助載波(沒有用xord,1,xord,2,xord,3索引)不受該命令的影響。此方法允許用信號傳遞多達8個輔助載波,但其需要兩個命令類型。出於圖示目的,如果接收到命令類型xodt,1,xodt,2,xodt,3=‘010’和命令位元xord,1,xord,2,xord,3=‘111’,則可以啟動與輔助載波索引7相關聯的輔助載波。或者,如果命令類型xodt,1,xodt,2,xodt,3=‘010’,則該命令是用於由xord,1,xord,2,xord,3指示的輔助載波索引的停用命令。如果命令類型xodt,1,xodt,2,xodt,3=‘011’,那麼該命令是用於由xord,1,xord,2,xord,3指示的輔助載波索引的啟動命令。 In the first embodiment, the command type indicates a start/deactivate command, and the command bit indicates the carrier to which the command is applied. For example, if the command type x odt,1 ,x odt,2 ,x odt,3 ='010', then the command is used for the auxiliary carrier index indicated by x ord,1 ,x ord,2 ,x ord,3 Start command. If the command type x odt,1 ,x odt,2 ,x odt,3 ='011', then the command is used to stop the auxiliary carrier index indicated by x ord,1 ,x ord,2 ,x ord,3 Use the command. Other auxiliary carriers (not indexed with x ord, 1 , x ord, 2 , x ord, 3 ) are not affected by this command. This method allows signaling up to 8 auxiliary carriers, but it requires two command types. For illustrative purposes, if the command type x odt,1, x odt,2 ,x odt,3 ='010' and the command bit x ord,1 ,x ord,2 ,x ord,3 ='111 are received ', then the supplementary carrier associated with the supplementary carrier index 7 can be activated. Or, if the command type x odt,1 ,x odt,2 ,x odt,3 ='010', the command is used for the auxiliary carrier index indicated by x ord,1 ,x ord,2 ,x ord,3 Deactivate command. If the command type x odt,1 ,x odt,2 ,x odt,3 ='011', then the command is used to start the auxiliary carrier index indicated by x ord,1 ,x ord,2 ,x ord,3 command.
在第二實施方式中,如果命令類型xodt,1,xodt,2,xodt,3=‘010’,則執行動態切換或是啟動/停用。然後,檢查命令位元來確定恰當的操作和輔助載波。如果命令位元xord,1=1,則啟動輔助載波1,如果命令位元xord,1=0,則停用輔助載波1。如果命令位元xord,2=1,則啟動輔助載波2,如果命令位元xord,2=0,則停用輔助載波2。如果命令位元xord,3=1,則啟動輔助載波3,如果命令位元xord,3=0,則停用輔助載波3。此實施方式使用了單一命令類型,並且可以同時啟動和停用至多三個輔助載波。 In the second embodiment, if the command type x odt,1 ,x odt,2 ,x odt,3 = '010', dynamic switching or start/deactivation is performed. The command bits are then checked to determine the appropriate operation and auxiliary carrier. If the command bit x ord, 1 =1, the auxiliary carrier 1 is activated, and if the command bit x ord, 1 =0, the supplementary carrier 1 is deactivated. If the command bit x ord, 2 =1, the secondary carrier 2 is activated, and if the command bit x ord, 2 =0, the secondary carrier 2 is deactivated. If the command bit x ord, 3 =1, the auxiliary carrier 3 is activated, and if the command bit x ord, 3 =0, the supplementary carrier 3 is deactivated. This embodiment uses a single command type and can simultaneously activate and deactivate up to three secondary carriers.
在另一個實施方式中,UTRAN發射用於同時啟動或停用一組載波的顯式信號。例如,下列方法中的任何一種或是其組合可以用於形成一組載波。在一個分組方法中,組可以由指定頻段中的所有輔助載波(用於上鏈、下鏈或是同時用於這二者)組成,其中該頻段與顯式訊息之間的關聯可以預先配置,也可以基於傳送顯式訊息的頻段而被暗指。在另一個分組方法中,組可以由所有輔助載波(上鏈、下鏈或是這二者)組成。在另一個分組方法中,組可以由與指定下鏈錨定載波關聯的所有下鏈輔助載波組成(無論是否處於相同頻段)。在另一個分組方法中,組可以由特定頻段中的所有載波(上鏈,下鏈,或是這二者)組成(即對特定頻段的接收進行停用或啟動)。此外,在另一個分組方法中,組可以由下鏈、上鏈或是這二者中的所有非錨定載波組成。在另一個分組方法中,組可以由作為載波組的一部分的所有載波組成,其中該載波組是下鏈及/或上鏈的預定列表,處於組內的下鏈及/或上鏈載波列表既可以在建立/重新配置無線電承載時經由無線電資源控制器(RRC)信令來預先配置,或在WTRU上預先配置。在另一個分組方法中,組可以由為載波組一部分的所有載波構成,其中該下鏈載波組可以被定義為是為WTRU分配了相同無線電網路臨時識別碼(RNTI)的所有載波,例如高速下鏈共用通道(HS-DSCH)-RNTI(H-RNTI),但其並不侷限於此。這裏揭露的示例分組方法適用於這裏描述的所有實施方式。 In another embodiment, the UTRAN transmits an explicit signal for simultaneously activating or deactivating a group of carriers. For example, any of the following methods, or a combination thereof, can be used to form a set of carriers. In a grouping method, a group may be composed of all auxiliary carriers (for uplink, downlink, or both) in a specified frequency band, wherein the association between the frequency band and the explicit message may be pre-configured. It can also be implied based on the frequency band in which the explicit message is transmitted. In another grouping method, a group can consist of all auxiliary carriers (uplink, downlink, or both). In another grouping method, a group may consist of all downlink-assisted carriers associated with a given downlink-anchor carrier (whether or not in the same frequency band). In another grouping method, a group may consist of all carriers (uplink, downlink, or both) in a particular frequency band (ie, deactivation or activation of reception of a particular frequency band). Furthermore, in another grouping method, a group may consist of a downlink, an uplink, or all non-anchor carriers in the two. In another grouping method, a group may be composed of all carriers that are part of a carrier group, wherein the carrier group is a predetermined list of downlinks and/or uplinks, and a list of downlink and/or uplink carriers within the group is The radio bearer may be pre-configured via Radio Resource Controller (RRC) signaling when establishing/reconfiguring the radio bearer, or pre-configured on the WTRU. In another grouping method, the group may be composed of all carriers that are part of a carrier group, which may be defined as all carriers that are assigned the same Radio Network Temporary Identification Number (RNTI) for the WTRU, such as high speed. Downlink shared channel (HS-DSCH)-RNTI (H-RNTI), but it is not limited thereto. The example grouping methods disclosed herein are applicable to all of the embodiments described herein.
在下文中將會概括揭露並且更詳細說明顯式信令的實施方式。在一個實施方式中,用於同時啟動或停用一組載波的顯式信號可以包括新的高速共用控制通道(HS-SCCH)命令,該命 令與用於啟動和停用次級服務HS-DSCH胞元的現有命令不同。在另一個實施方式中,顯式信號可以是用於啟動和停用次級服務HS-DSCH胞元的現有命令,其中舉例來說,在配置WTRU用於執行多載波操作時,該命令將被重新解釋,由此不但指示啟動和停用次級服務HS-DSCH胞元,而且還指示啟動和停用一組載波(例如所有補充服務HS-DSCH胞元載波)。該示例命令可以應用於那些在其各自波段中被視為“輔助”的載波。例如,啟動/停用命令不能應用於那些在指定波段中被作為錨載波的下鏈(DL)載波。 Embodiments of explicit signaling will be generally disclosed and described in greater detail below. In one embodiment, an explicit signal for simultaneously enabling or disabling a group of carriers may include a new High Speed Shared Control Channel (HS-SCCH) command, the command It is different from the existing commands used to start and deactivate secondary service HS-DSCH cells. In another embodiment, the explicit signal may be an existing command for initiating and deactivating the secondary serving HS-DSCH cell, where, for example, when configuring the WTRU to perform multi-carrier operation, the command will be Reinterpreted, thereby not only indicating the initiation and deactivation of secondary service HS-DSCH cells, but also initiating and deactivating a set of carriers (e.g., all supplementary services HS-DSCH cell carriers). This example command can be applied to those carriers that are considered "auxiliary" in their respective bands. For example, the start/deactivate command cannot be applied to those downlink (DL) carriers that are used as anchor carriers in the specified band.
在另一個實施方式中,顯式信號可以是用於同時啟動或停用一組載波的L2或L3顯式訊息。 In another embodiment, the explicit signal may be an L2 or L3 explicit message for simultaneously enabling or deactivating a group of carriers.
對這裏揭露的顯式實施方式來說,顯式訊息可以應用於傳送該訊息的波段中的載波。 For the explicit implementations disclosed herein, explicit messages can be applied to carriers in the band in which the message is transmitted.
對這裏揭露的顯式實施方式來說,顯式訊息可以應用於與相同錨定載波相關聯的輔助載波。 For the explicit implementations disclosed herein, explicit messages can be applied to the secondary carriers associated with the same anchor carrier.
在下文中將會描述以每一載波為基礎或者以單一或每一配對載波(該載波可以是預先定義、預先指定或預先配置的)為基礎實施的各種次級載波啟動/停用方法的細節。可以使用多個HS-SCCH命令來同時啟動/停用多個載波。 Details of various secondary carrier activation/deactivation methods implemented on a per carrier basis or on a single or each paired carrier (which may be pre-defined, pre-specified or pre-configured) will be described below. Multiple HS-SCCH commands can be used to simultaneously enable/deactivate multiple carriers.
在一個實施方式中,用於指示次級載波啟動/停用的現有命令類型會與各種命令映射方法結合而被再次使用,以提供啟動/停用命令以及指示啟動/停用命令所適用的目標載波(或目標配對載波)。對DC-HSPA來說,對於現有命令類型xodt,1,xodt,2,xodt,3=‘001’,三個位元命令(xord,1,xord,2,xord,3)被用於第一次級 載波的UL和DL啟動和停用。在本實施方式中將各種命令映射方法與重新使用現有命令類型(xodt,1,xodt,2,xodt,3)=‘001’的處理結合使用,以便單獨為存在多個次級載波的MC-HSPA啟動/停用目標次級載波。 In one embodiment, existing command types for indicating secondary carrier activation/deactivation are reused in conjunction with various command mapping methods to provide start/deactivate commands and targets to which the start/deactivate command is directed. Carrier (or target paired carrier). For DC-HSPA, for existing command types x odt, 1 , x odt , 2 , x odt , 3 = '001 ', three bit commands (x ord,1 ,x ord,2 ,x ord,3 ) UL and DL start and deactivation for the first secondary carrier. In the present embodiment, various command mapping methods are used in combination with the process of reusing the existing command type (x odt,1 ,x odt,2 ,x odt,3 )='001', so that there are multiple secondary carriers separately. The MC-HSPA starts/deactivates the target secondary carrier.
在第一方法中,配置單一UL載波。在配置單一UL載波時,在具有至多四個DL載波的MC-HSDPA系統中可以用三位元命令來支援次級載波的啟動/停用。在這裏可以使用一個二進位命令位元來指示每一個次級DL載波的啟動或停用(命令位元“1”和“0”分別可以指示啟動和停用或是停用和啟動)。剩餘命令位元則可以指示該命令所應用的目標次級DL載波的索引,因此,對於三個次級DL載波來說,單獨的啟動/停用只需要三個命令位元。該方法可以應用於具有多達K個DL載波的MC-HSDPA系統。對於(K-1)個次級DL載波來說,其單獨的啟動/停用有可能需要N個命令位元,其中N是整數,滿足N[1+log2(K-1)]。命令位元與載波之間的映射可以在任何命令中指示。在一個實例中,不同的HS-SCCH命令可以被單獨發送,以便以表1實例的方式來啟動和停用每一個下鏈載波,其中表1代表的是用於在配置了四個DL載波的MC-HSDPA中啟動/停用次級載波的HS-SCCH命令。應該理解到,實際的命令-位元映射可以採用與表1中所示不同的形式。還應該理解的是,這個概念在DL載波少於四個的時候也是適用的。在這種情況下,與未被配置的載波的啟動和停用相關聯的命令將會變為“保留(reserved)”。該處理可以應用於這裏論述的所有實施方式。如下所示的實際的命令-位元映射可以基於每一載波或是每一組來應用。 In the first method, a single UL carrier is configured. When configuring a single UL carrier, a three-bit command can be used to support the activation/deactivation of the secondary carrier in an MC-HSDPA system with up to four DL carriers. A binary command bit may be used herein to indicate the activation or deactivation of each secondary DL carrier (command bits "1" and "0" may indicate activation and deactivation or deactivation and activation, respectively). The remaining command bits may then indicate the index of the target secondary DL carrier to which the command applies, so for three secondary DL carriers, only three command bits are required for a separate start/deactivation. The method can be applied to an MC-HSDPA system with up to K DL carriers. For (K-1) secondary DL carriers, a separate start/deactivation may require N command bits, where N is an integer and satisfies N [1+log 2 (K-1)]. The mapping between command bits and carriers can be indicated in any command. In one example, different HS-SCCH commands may be sent separately to enable and deactivate each of the downlink carriers in the manner of the Table 1 example, where Table 1 represents for configuring four DL carriers. The HS-SCCH command to start/deactivate the secondary carrier in MC-HSDPA. It should be understood that the actual command-bit mapping can take a different form than that shown in Table 1. It should also be understood that this concept is also applicable when the DL carrier is less than four. In this case, the command associated with the initiation and deactivation of the unconfigured carrier will become "reserved." This process can be applied to all of the embodiments discussed herein. The actual command-bit mapping as shown below can be applied on a per carrier basis or per group basis.
在第二方法中,配置了多個UL載波。以下一組實施方式針對的是配置了兩個UL載波的情況,並且可以對現有的三個位元xord,1,xord,2和xord,3進行重新解釋來實現輔助載波的啟動/停用。應該指出的是,這些實施方式也可以在配置了單一UL載波的時候使用。 In the second method, a plurality of UL carriers are configured. The following set of embodiments is directed to the case where two UL carriers are configured, and the existing three bits x ord,1 ,x ord,2 and x ord,3 can be reinterpreted to implement the auxiliary carrier activation/ Disabled. It should be noted that these embodiments can also be used when a single UL carrier is configured.
在下表2中顯示了一個示例實施方式,其中每一個HS-SCCH命令都可以啟動/停用單一DL載波或配對DL/UL載波,這一點可以用一個命令位元來指示,而剩餘命令則可以指示用於目標載波或目標配對載波的啟動/停用命令。如果xord,1=0,則該命令是用於配對DL1/UL1載波的啟動/停用命令。如果xord,1=1,則該命令是用於單一DL載波(即DL2或DL3)的啟動/停用命令。換句話說,為了啟動或停用多個下鏈載波,節點B可以發送多個HS-SCCH命令。應該理解的是,實際的命令-位元映射可以採用不同於第2圖所示的形式,在表2中顯示的是用於在MC-HSPA中啟動/停用次級載波的示例HS-SCCH命 令。 An example implementation is shown in Table 2 below, where each HS-SCCH order can initiate/deactivate a single DL carrier or a paired DL/UL carrier, which can be indicated by one command bit, while the remaining commands can Indicates a start/deactivate command for the target carrier or target paired carrier. If x ord, 1 =0, then the command is a start/deactivate command for pairing DL1/UL1 carriers. If x ord, 1 =1, then the command is a start/deactivate command for a single DL carrier (ie DL2 or DL3). In other words, in order to initiate or deactivate multiple downlink carriers, the Node B can send multiple HS-SCCH commands. It should be understood that the actual command-bit mapping may take a different form than that shown in Figure 2, which shows an example HS-SCCH for enabling/deactivating secondary carriers in MC-HSPA. command.
在另一個示例實施方式中,如表3所示,DL2和DL3這類預先規定的下鏈載波可以用單一HS-SCCH命令同時啟動或停用。在本實例中,位元xord,2用於指示啟動或停用DL2,xord,3位元則用於指示啟動或停用DL3。應該理解的是,實際的命令-位元映射可以採用不同於表3所示的形式,表3顯示的是用於在MC-HSPA中啟動/停用次級載波的示例HS-SCCH命令。 In another example embodiment, as shown in Table 3, pre-defined downlink carriers such as DL2 and DL3 may be simultaneously enabled or disabled with a single HS-SCCH order. In this example, the bit x ord, 2 is used to indicate the activation or deactivation of DL2, x ord, and the 3- bit is used to indicate the activation or deactivation of DL3. It should be understood that the actual command-bit mapping may take a form other than that shown in Table 3, which shows an example HS-SCCH order for starting/deactivating secondary carriers in MC-HSPA.
另一組實施方式可以在UL中配置了多達四個載波的時候使用。應該指出的是,在配置了單一UL載波的時候,這些實施方式也是適用的。 Another set of implementations can be used when up to four carriers are configured in the UL. It should be noted that these embodiments are also applicable when a single UL carrier is configured.
作為其中一個實施方式的一部分,第二和第三次級載波配對(也就是DL2/UL2和DL3/UL3)的啟動/停用可以一起用信號通知。例如,HS-SCCH命令“111”、“101”和“100”可以用於同時啟動/停用第二和第三次級載波的UL和DL。在表4中顯示了一個示例實施方式,其中表4顯示的是用於在MC-HSPA中啟動/停用次級載波的示例HS-SCCH命令。在本實施方式中,如果xord,1=0,則可以將版本9的DC-HSUPA命令映射應用於第一次級載波。如果xord,1=1,則可以將版本9的DC-HSUPA命令映射同時應用於第二和第三次級載波。在不考慮向後相容版本9的DC-HSUPA的情況下,此實施方式可以應用於其他兩種組合,即同時用信號通知第一和第二次級載波或是同時用信號通知第一和第三載波。 As part of one of the embodiments, the activation/deactivation of the second and third secondary carrier pairings (ie, DL2/UL2 and DL3/UL3) can be signaled together. For example, the HS-SCCH commands "111", "101", and "100" may be used to simultaneously activate/deactivate the UL and DL of the second and third secondary carriers. An example embodiment is shown in Table 4, where Table 4 shows an example HS-SCCH order for initiating/deactivating secondary carriers in MC-HSPA. In this embodiment, if x ord, 1 =0, the version 9 DC-HSUPA command mapping can be applied to the first secondary carrier. If x ord, 1 =1, the version 9 DC-HSUPA command map can be applied to both the second and third secondary carriers. In the case where the DC-HSUPA of the backward compatible version 9 is not considered, this embodiment can be applied to the other two combinations, that is, simultaneously signaling the first and second secondary carriers or simultaneously signaling the first and the Three carriers.
在用於4個DL和4個DL載波啟動/停用的替代實施方式中,UL/DL載波配對是使用用於UL和DL第二載波的單一啟動/停用命令及/或用於UL和DL第三載波的單一啟動/停用命令同時為第二和第二次級載波啟動/停用的。 In an alternative embodiment for 4 DL and 4 DL carrier activation/deactivation, UL/DL carrier pairing is a single start/deactivation command for UL and DL second carriers and/or for UL and A single start/deactivate command for the DL third carrier is simultaneously enabled/disabled for the second and second secondary carriers.
在一個實施方式中,可以用於發送命令的HS-SCCH數量隱含指示了以哪一個載波或載波組為目標。在一個說明性實施方式中,如果(HS-SCCH數量)模2=0,則HS-SCCH命令的目標僅僅是第一次級載波:011意味著同時啟動第一次級UL和DL;001意味著啟動第一次級DL和停用次級UL;000則意味著停用第一次級UL和DL。如果(HS-SCCH數量)模2=1,則HS-SCCH命令的目標是第二和第三載波:011意味著啟動第二次級UL和DL;001意味著啟動第二次級DL和停用次級UL;000意味著停用第二次級UL和DL;111意味著啟動第三UL和DL;101意味著啟動第三次級DL和停用次級UL;以及100意味著停用第三次級UL和DL。 In one embodiment, the number of HS-SCCHs that may be used to transmit a command implicitly indicates which carrier or group of carriers is targeted. In an illustrative embodiment, if (HS-SCCH number) modulo 2 = 0, the target of the HS-SCCH order is only the first secondary carrier: 011 means that the first secondary UL and DL are simultaneously activated; 001 means Starting the first secondary DL and deactivating the secondary UL; 000 means deactivating the first secondary UL and DL. If (HS-SCCH number) modulo 2 = 1, the target of the HS-SCCH order is the second and third carriers: 011 means to start the second secondary UL and DL; 001 means to start the second secondary DL and stop Using the secondary UL;000 means deactivating the second secondary UL and DL; 111 means starting the third UL and DL; 101 means starting the third secondary DL and deactivating the secondary UL; and 100 means deactivating Third secondary UL and DL.
或者,如果(HS-SCCH數量)模2=0,則HS-SCCH命令的目標可以是第二次級載波。如果(HS-SCCH數量)模2=1,則HS-SCCH命令的目標可以是第一和第三載波。在另一個變型中,如果(HS-SCCH數量)模2=0,則HS-SCCH命令的目標也可以是第三次級載波。如果(HS-SCCH數量)模2=1,那麼HS-SCCH命令的目標可以是第一和第二載波。如上述實例所示,這些命令將被相應地應用於這些目標載波。 Alternatively, if (HS-SCCH number) modulo 2 = 0, the target of the HS-SCCH order may be the second secondary carrier. If (HS-SCCH number) modulo 2 = 1, the target of the HS-SCCH order may be the first and third carriers. In another variation, if (HS-SCCH number) modulo 2 = 0, the target of the HS-SCCH order may also be the third secondary carrier. If (HS-SCCH number) modulo 2 = 1, the target of the HS-SCCH order may be the first and second carriers. As shown in the above examples, these commands will be applied to these target carriers accordingly.
在另一個示例實施方式中,如果(HS-SCCH數量)模2=0,那麼HS-SCCH命令的目標可以是第一和第二次級載波:011意味著啟動第一次級UL和DL;001意味著啟動第一次級DL以及停用次級UL;000意味著停用第一次級DL和DL;111意味著啟動第二次級UL和DL;101意味著啟動第二次級DL以及停用次級UL;100意味著停用第二次級UL和DL。如果(HS-SCCH數量)模2=1,那麼HS-SCCH命令的目標可以是第三次級載波--011意味著啟動第三次級UL和DL;001意味著啟動第三次級DL以及停用第二UL;000則意味著停用第三次級UL和DL。 In another example embodiment, if (HS-SCCH number) modulo 2 = 0, the target of the HS-SCCH order may be the first and second secondary carriers: 011 means that the first secondary UL and DL are activated; 001 means starting the first secondary DL and deactivating the secondary UL; 000 means deactivating the first secondary DL and DL; 111 means starting the second secondary UL and DL; 101 means starting the second secondary DL And deactivating the secondary UL; 100 means deactivating the second secondary UL and DL. If (HS-SCCH number) modulo 2 = 1, then the target of the HS-SCCH order may be the third secondary carrier - 011 means that the third secondary UL and DL are activated; 001 means that the third secondary DL is started and Deactivating the second UL;000 means deactivating the third secondary UL and DL.
在另一個實施方式中,如果(HS-SCCH數量)模2=0,那麼HS-SCCH命令的目標可以是第二和第三次級載波。如果(HS-SCCH數量)模2=1,那麼HS-SCCH命令的目標可以是第一載波。或者,如果(HS-SCCH數量)模2=0,那麼HS-SCCH命令的目標可以是第一和第三次級載波。如果(HS-SCCH數量)模2=1,那麼HS-SCCH命令的目標可以是第二載波。如以上實例所示,這些命令將會相應地應用於這些目標載波。 In another embodiment, if (HS-SCCH number) modulo 2 = 0, then the target of the HS-SCCH order may be the second and third secondary carriers. If (HS-SCCH number) modulo 2 = 1, the target of the HS-SCCH order may be the first carrier. Alternatively, if (HS-SCCH number) modulo 2 = 0, then the target of the HS-SCCH order may be the first and third secondary carriers. If (HS-SCCH number) modulo 2 = 1, the target of the HS-SCCH order may be the second carrier. As shown in the example above, these commands will be applied to these target carriers accordingly.
在另一個說明性實施方式中,如果(HS-SCCH)模2=0,那麼HS-SCCH命令的目標可以是所配置的第一頻段中的所有載波。同樣,如果(HS-SCCH數量)模2=1,那麼HS-SCCH命令的目標可以是所配置的次級頻段中的所有載波。 In another illustrative embodiment, if (HS-SCCH) modulo 2 = 0, then the target of the HS-SCCH order may be all carriers in the configured first frequency band. Similarly, if (HS-SCCH number) modulo 2 = 1, the target of the HS-SCCH order may be all carriers in the configured secondary frequency band.
在另一個實施方式中,停用處理所針對的載波或載波組可以根據在哪一個載波上傳送HS-SCCH命令來確定。換句話說,停用命令可以在將要停用的載波上傳送。另一方面,啟動命令可以在任何活動載波上發送。在表5中顯示了一個示例實現方式,其中DLrx和ULrx對應的是與接收HS-SCCH命令的DL載波相關聯的UL和DL載波。表5顯示了一個用於在MC-HSPA中啟動/停用次級載波的HS-SCCH命令。 In another embodiment, the carrier or group of carriers for which the deactivation process is directed may be determined based on which carrier is transmitted on the HS-SCCH order. In other words, the disable command can be transmitted on the carrier to be deactivated. On the other hand, the start command can be sent on any active carrier. One example implementation is shown in Table 5, where DLrx and ULrx correspond to UL and DL carriers associated with a DL carrier receiving an HS-SCCH order. Table 5 shows an HS-SCCH order for starting/deactivating secondary carriers in MC-HSPA.
作為選擇,“100”可以用於同時停用所有載波。 Alternatively, "100" can be used to disable all carriers simultaneously.
在另一個實施方式中,停用處理所針對的載波或載波組可以根據在哪一個頻段上傳送HS-SCCH命令來確定。在一個實例中,用於指定頻段中的所有載波的停用命令可以在將被停用的 頻段的任何載波上發送。另一方面,啟動命令也可以在任何活動的載波上發送。 In another embodiment, the carrier or group of carriers for which the deactivation process is directed may be determined based on which frequency band the HS-SCCH order is transmitted. In one example, a disable command for all carriers in a specified frequency band may be deactivated Transmitted on any carrier of the band. On the other hand, the start command can also be sent on any active carrier.
在這裏揭露的是引入新的命令類型來支持次級載波的啟動/停用的實施方式。在一個實施方式中,可用HS-SCCH命令的數量可以使用附加命令類型來提高。這樣做允許添加更多的HS-SCCH命令,並且這些命令可以用於啟動和停用次級UL和DL載波。在下表6所示的示例實現方式中,命令類型xodt,1,xodt,2,xodt,3=‘001’可用於發送命令,以啟動和停用次級DL1、DL2、UL1和UL2,此外,引入新的命令類型xodt,1,xodt,2,xodt,3=‘010’,以啟動和停用DL3和UL3。表6示出了用於在MC-HSPA中啟動/停用次級載波的HS-SCCH命令。 Disclosed herein are implementations that introduce new command types to support the initiation/deactivation of secondary carriers. In one embodiment, the number of available HS-SCCH commands can be increased using additional command types. Doing so allows for the addition of more HS-SCCH commands, and these commands can be used to start and deactivate secondary UL and DL carriers. In the example implementation shown in Table 6 below, the command type x odt,1 ,x odt,2 ,x odt,3 = '001' can be used to send commands to enable and disable secondary DL1, DL2, UL1, and UL2. In addition, a new command type x odt,1 ,x odt,2 ,x odt,3 ='010' is introduced to enable and disable DL3 and UL3. Table 6 shows the HS-SCCH order for starting/deactivating secondary carriers in MC-HSPA.
在另一個實施方式中,作為HS-SCCH命令一部分發送的命令類型可以用於區分載波。在3GPP版本9中,命令類型xodt,1,xodt,2,xodt,3=‘000’可以用於用信號通知與DTX、DRX以及HS-SCCH-less操作相關的命令,而命令類型xodt,1,xodt,2,xodt,3=‘001’則可以用於規定啟動/停用DL1和UL1。作為本實施方式的一部分,在這裏可以定義新的命令類型,以便啟動和停用每一個附加DL載波(有可能是相應的UL載波)。舉例來說,在用信號通知啟動/停用DL2和UL2的時候,可以使用xodt,1,xodt,2,xodt,3=‘010’,而xodt,1,xodt,2,xodt,3=‘011’則可以用於用信號通知啟動/停用DL3和UL3。應該理解的是,其他任何可用的命令類型均可用於用信號通知特定DL和UL配對的啟動/停用。目前為3GPP版本9定義的現有命令位元xord,1,xord,2,xord,3可以重新用於每一個DL和UL配對。然後,這些載波配對可以用命令類型加以區分。 In another embodiment, the type of command sent as part of the HS-SCCH order can be used to distinguish between carriers. In 3GPP Release 9, the command type x odt,1 ,x odt,2 ,x odt,3 ='000' can be used to signal commands related to DTX, DRX, and HS-SCCH-less operations, while command types x odt,1 ,x odt,2 ,x odt,3 ='001' can be used to specify start/deactivate DL1 and UL1. As part of this embodiment, a new command type can be defined here to initiate and deactivate each additional DL carrier (possibly the corresponding UL carrier). For example, when signaling DL2 and UL2 to start/deactivate, you can use x odt,1 ,x odt,2 ,x odt,3 ='010', and x odt,1 ,x odt,2 , x odt, 3 = '011' can be used to signal start/deactivate DL3 and UL3. It should be understood that any other available command types can be used to signal the activation/deactivation of a particular DL and UL pair. The existing command bits x ord,1 ,x ord,2 ,x ord,3 currently defined for 3GPP Release 9 can be reused for each DL and UL pairing. These carrier pairs can then be distinguished by command type.
在一個替代實施方式中,在具有4個DL和4個UL載波的MC-HSPA系統中,提高HS-SCCH命令欄位的位元數量,以啟動/停用次級載波。對於所添加的一個或多個命令位元(例如xord,4)來說,這些位元可以源自傳輸塊大小資訊(xtbspb,1,xtbspb,2……,xtbspb,6)欄位的六個位元及/或1位元新資料指示符(xnd,1)欄位中的任何一者。應該理解的是,在藉由這裏描述的任何一種方法增大了命令及/或命令類型的長度之後,各種具有三位元命令類型和三位元命令的啟動/停用命令映射方案都是可以使用的。 In an alternate embodiment, in an MC-HSPA system with 4 DL and 4 UL carriers, the number of bits of the HS-SCCH command field is increased to enable/deactivate secondary carriers. For one or more command bits added (for example, x ord, 4 ), these bits can be derived from the transport block size information (x tbspb,1 , x tbspb,2 ..., x tbspb,6 ) Any of the six bits of the bit and/or the 1-bit new data indicator (x nd, 1 ) field. It should be understood that after increasing the length of the command and/or command type by any of the methods described herein, various start/deactivate command mapping schemes having a three-bit command type and a three-bit command are possible. in use.
在一個替代實施方式中,HS-SCCH命令類型位元中的一個或兩個可以被重新解釋為HS-SCCH命令位元。例如,將xodt,1 位元解釋為xord,4,從而提供更多的HS-SCCH命令。 In an alternate embodiment, one or both of the HS-SCCH command type bits may be reinterpreted as HS-SCCH command bits. For example, x odt, 1 bit is interpreted as x ord, 4 , providing more HS-SCCH commands.
在一個替代實施方式中,在將WTRU配置在多載波模式的時候,可以引入類型4這類新的HS-SCCH類型,以便傳送HS-SCCH命令。WTRU配置可以從較高層用信號通知。可以構造HS-SCCH類型4來提供足夠的命令位元,以便在MC-HSPA系統中啟動/停用次級載波。 In an alternate embodiment, a new HS-SCCH type of type 4 may be introduced to configure the HS-SCCH order when the WTRU is configured in multi-carrier mode. The WTRU configuration can be signaled from a higher layer. HS-SCCH Type 4 can be constructed to provide sufficient command bits to enable/deactivate secondary carriers in the MC-HSPA system.
在一個替代實施方式中,按順序使用單一HS-SCCH命令集合(或是集合的組合),以啟動/停用DL及/或UL載波。在這裏對照第5圖顯示了一個實例,其中狀態505包括活動載波DL0和UL0,並且在狀態510中,命令“001”進一步啟動了DL1。此外,在狀態515和520中可以引入新的命令集合“101”、“111”和“100”,以分別啟動/停用載波DL2、UL2、DL3和UL3。應該指出的是,在本實例中,現有的3GPP版本9中的命令“001”、“011”和“000”可以用於啟動DL1和UL1。或者,在任何狀態中都可以使用“000”,以便返回到基本狀態505,在該狀態中所有次級載波被停用。 In an alternate embodiment, a single HS-SCCH order set (or a combination of sets) is used in sequence to enable/disable DL and/or UL carriers. An example is shown here with respect to Figure 5, where state 505 includes active carriers DL0 and UL0, and in state 510, command "001" further initiates DL1. In addition, new command sets "101", "111", and "100" may be introduced in states 515 and 520 to enable/deactivate carriers DL2, UL2, DL3, and UL3, respectively. It should be noted that in this example, the commands "001", "011", and "000" in the existing 3GPP Release 9 can be used to start DL1 and UL1. Alternatively, "000" can be used in any state to return to the base state 505, in which all secondary carriers are deactivated.
現在將要揭露的是基於組實施的次級載波啟動/停用方法。在另一個實施方式中,所提出的是對次級載波組進行定義,以便將單一啟動/停用命令應用於整個載波組。這種分組方式可以使用上文揭露的封包方法中的任何一種或是其組合來確定。 What will now be disclosed is a secondary carrier start/stop method based on group implementation. In another embodiment, it is proposed to define a secondary carrier group to apply a single start/deactivate command to the entire carrier group. This grouping can be determined using any one of the packet methods disclosed above or a combination thereof.
在這些方法中,UTRAN可以傳送用於同時啟動或停用載波組的顯式信號,以便降低控制信令負荷。在上文中為單一載波啟動/停用所定義的信令機制同樣可以應用於載波組的啟動/停用方法。 In these methods, the UTRAN can transmit an explicit signal for simultaneously starting or deactivating a carrier group in order to reduce the control signaling load. The signaling mechanism defined above for single carrier start/deactivation can also be applied to the start/stop method of the carrier group.
在一個示例方法中,(xodt,1,xodt,2,xodt,3)這類新的HS-SCCH命令類型可以用於用信號通知WTRU將啟動/停用命令應用於特定載波組。在本實例中,命令類型“010”用於向WTRU用信號通知可以為組下鏈1(GDL1)及/或組上鏈1(GUL1)中定義的所有載波使用啟動/停用命令。表7顯示的是為4個DL+2個UL載波使用新的HS-SCCH命令類型的組協同(group-wise)啟動/停用的示例實現方式。 In one example method, a new HS-SCCH order type such as (x odt, 1 , x odt, 2 , x odt, 3 ) may be used to signal the WTRU to apply an enable/disable command to a particular carrier group. In this example, the command type "010" is used to signal to the WTRU that the start/deactivate command can be used for all carriers defined in Group Downlink 1 (GDL1) and/or Group Uplink 1 (GUL1). Table 7 shows an example implementation of group-wise start/deactivation using a new HS-SCCH order type for 4 DL+2 UL carriers.
在另一個示例方法中,組命令可用於停用載波,並且一個或多個載波的啟動可以如上文揭露的那樣藉由單一命令或是基於每一載波來完成。例如,具有命令位元“000”的現有命令類型“001”的範圍可以是用於所有已配置載波的命令。同樣,節點B傳輸該命令的處理可以用於用信號通知停用所有已啟動的 DL和UL載波。 In another example method, a group command can be used to deactivate a carrier, and activation of one or more carriers can be accomplished by a single command or on a per carrier basis as disclosed above. For example, the range of existing command type "001" with command bit "000" may be a command for all configured carriers. Similarly, the process by which Node B transmits the command can be used to signal that all activated devices are disabled. DL and UL carrier.
在另一個實施方式中,單一HS-SCCH命令可以用於同時啟動及/或停用所有已配置的次級UL和DL載波中的任何一個。對於與命令位元相結合的命令類型所代表的每一個HS-SCCH命令來說,這些命令為所有已配置的次級UL和DL載波都指示了一個狀態,並且命令與狀態之間的映射可以按照任何順序進行。在給出了不同載波配置(例如4個DL+1個UL、4個DL+2個UL、4個DL+3個UL以及4個DL+4個UL)的情況下,所產生的啟動/停用載波狀態的總數分別是8、12、18和27。這意味著可以用三位元命令來表示4個DL+1個UL個載波,而具有三個以上的位元的命令則是支持具有多個UL載波的配置(例如,4個DL+2個DL、4個DL+3個UL以及4個DL+4個UL,但其並不侷限於此)所必需的。應該指出的是,上述實施方式假設的是只有次級載波可以被HS-SCCH命令啟動/停用。但是,同時啟動/停用所有已配置的載波的處理同樣可以應用於啟動/停用主DL/UL載波的情形。 In another embodiment, a single HS-SCCH order can be used to simultaneously initiate and/or deactivate any of the configured secondary UL and DL carriers. For each HS-SCCH order represented by the command type combined with the command bit, these commands indicate a status for all configured secondary UL and DL carriers, and the mapping between commands and states can In any order. In the case where different carrier configurations (eg, 4 DL+1 UL, 4 DL+2 UL, 4 DL+3 UL, and 4 DL+4 UL) are given, the generated boot/ The total number of disabled carrier states is 8, 12, 18, and 27, respectively. This means that four DL+1 UL carriers can be represented by a three-bit command, while a command with more than three bits supports a configuration with multiple UL carriers (for example, four DL+2) DL, 4 DL + 3 UL, and 4 DL + 4 UL, but it is not limited to this). It should be noted that the above embodiment assumes that only the secondary carrier can be activated/deactivated by the HS-SCCH order. However, the process of simultaneously enabling/deactivating all configured carriers can also be applied to the case of starting/deactivating the primary DL/UL carrier.
在單一UL載波的配置中,由於可以從目前規定的HS-SCCH命令中得到三位元命令(xord,1,xord,2,xord,3),因此,現有命令類型(xodt,1,xodt,2,xodt,3)=“001”和三位元命令可以用於啟動/停用次級載波。在表8中顯示了一個實例,在該示例中可以使用不同的HS-SCCH命令來顯式指示哪些載波可被啟動及/或哪些載波可被停用。與表1的在先實施方式相比,此實施方式的優點是可以使用單一命令來同時啟動/停用多個載波。應該理解的是,實際的命令-位元映射可以採用不同於第8圖所示的形式。此外還應該理解,為每一個命令定義的載波配置的實際 組合也可以採用不同的形式。 In the configuration of a single UL carrier, since the three-bit command (x ord,1 ,x ord,2 ,x ord,3 ) can be obtained from the currently specified HS-SCCH command, the existing command type (x odt, 1 , x odt, 2 , x odt, 3 ) = “001” and a three-bit command can be used to start/deactivate the secondary carrier. An example is shown in Table 8, in which different HS-SCCH commands can be used to explicitly indicate which carriers can be enabled and/or which carriers can be deactivated. An advantage of this embodiment over the prior embodiments of Table 1 is that a single command can be used to simultaneously activate/deactivate multiple carriers. It should be understood that the actual command-bit mapping can take a different form than that shown in FIG. It should also be understood that the actual combination of carrier configurations defined for each command may take a different form.
在多UL載波配置範例中,現有命令類型和三位元命令未必足以映射所得到的啟動/停用載波狀態。這種情況可以使用下列方法之一或是其組合來加以克服。 In the multi-UL carrier configuration example, the existing command type and three-bit command are not necessarily sufficient to map the resulting start/deactivate carrier state. This situation can be overcome using one of the following methods or a combination thereof.
在第一方法中,為MC-HSPA定義了新的命令類型。目前的HS-SCCH命令實體通道中有三位元命令類型(xodt,1,xodt,2,xodt,3),它可以代表八種命令類型。在版本9的DC-HSUPA中,使用的是命令類型xodt,1,xodt,2,xodt,3=‘000’以及命令類型xodt,1,xodt,2,xodt,3=‘001’的一部分。定義新的命令類型,使得在具有一個以上的已配置UL載波的MC-HSPA中可用更多命令來映射所有產生的啟動/停用載波狀態。 In the first method, a new command type is defined for MC-HSPA. The current HS-SCCH command entity channel has a three-bit command type (x odt,1 ,x odt,2 ,x odt,3 ), which can represent eight command types. In version 9 of DC-HSUPA, the command type x odt,1 ,x odt,2 ,x odt,3 ='000' and the command type x odt,1 ,x odt,2 ,x odt,3 = are used. Part of '001'. A new command type is defined such that more commands are available in the MC-HSPA with more than one configured UL carrier to map all generated start/deactivate carrier states.
例如,為了支持4個DL和4個UL載波,有必要組合命令類型和命令位元來控制所產生的27種載波配置狀態。三位元命令類型(xodt,1,xodt,2,xodt,3)提供了七種命令類型,它可以與三位元命令(xord,1,xord,2,xord,3)結合來創建足夠的命令。表9示出了 被保留的(可用)命令和具有4個DL和4個UL載波的MC-HSPA系統的所有產生的載波配置之間的映射的一個實例。應該理解的是,實際的命令-位元映射可以採用不同於表9所示的形式。此外還應該理解,為每一個命令定義的實際載波組合可以採用不同的形式。 For example, to support 4 DL and 4 UL carriers, it is necessary to combine the command type and command bits to control the 27 carrier configuration states generated. The three-bit command type (x odt,1 ,x odt,2 ,x odt,3 ) provides seven command types, which can be combined with three-bit commands (x ord,1 ,x ord,2 ,x ord,3 ) Combine to create enough commands. Table 9 shows an example of a mapping between a reserved (available) command and all generated carrier configurations of an MC-HSPA system with 4 DL and 4 UL carriers. It should be understood that the actual command-bit mapping can take a different form than that shown in Table 9. It should also be understood that the actual carrier combinations defined for each command may take different forms.
在第二方法中,命令的長度可以增大。該處理可以藉由將命令類型重新解釋為命令位元來實現。這樣做會將命令位元的長度從三位元增大到六位元(來自命令類型的三個位元加上來自命令的三個位元)。這樣則可以充分支持4個DL+4個UL載波。根據是否向後相容版本9的DC-HSUPA,與三位元命令結合的命令類型xodt,1,xodt,2,xodt,3=‘000’可以用於也可以不用於啟動和停用MC-HSPA的次級載波。如先前所指,這些命令過去被用於啟動/停用DTX、DRX和HS-SCCH-less操作,以及用於版本9中的HS-DSCH服務胞元變更。 In the second method, the length of the command can be increased. This processing can be implemented by reinterpreting the command type as a command bit. Doing so increases the length of the command bit from three bits to six bits (three bits from the command type plus three bits from the command). This can fully support 4 DL+4 UL carriers. Depending on whether the backward-compatible version 9 DC-HSUPA, the command type x odt,1 ,x odt,2 ,x odt,3 ='000' combined with the three-bit command can be used or not used to start and deactivate The secondary carrier of the MC-HSPA. As previously indicated, these commands were used in the past to enable/disable DTX, DRX, and HS-SCCH-less operations, as well as for HS-DSCH service cell changes in Release 9.
在替代方法中,所保留的新的資料指示符與傳輸塊大小資訊的一部分結合,並且可以被重新解釋為命令類型及/或命令。由於沒有HS-PDSCH是與HS-SCCH命令相關聯,因此,使用或重新解釋六位元傳輸塊大小資訊(xtbspb,1,xtbspb,2,…,xtbspb,6)的一部分及/或1位元的新資料指示符(xnd,1),可以增大命令的長度。例如,(xtbspb,5,xtbspb,6)和xnd,1可以用於增大HS-SCCH類型1的命令的長度。舉個例子,如果使用了xnd,1,則可以將xnd,1設定為用於HS-SCCH命令(HS-SCCH類型1)的xord,4。另舉一例,如果使用了(xtbspb,4,xtbspb,5,xtbspb,6),那麼HS-SCCH命令(HS-SCCH類型3)可以是:xtbspb,1,xtbspb,2,…,xtbspb,6,並且可 以將其設定為‘1,1,1,xord,4,xord,5,xord,6。應該理解的是,重新解釋後的位元可以映射到命令類型或命令中的任何位元。 In an alternative method, the retained new data indicator is combined with a portion of the transport block size information and can be reinterpreted as a command type and/or command. Since no HS-PDSCH is associated with the HS-SCCH order, a portion of the six-bit transport block size information (x tbspb,1 , x tbspb,2 ,..., x tbspb,6 ) is used or reinterpreted and/or A 1-bit new data indicator (x nd,1 ) can increase the length of the command. For example, (x tbspb,5 , x tbspb,6 ) and x nd,1 can be used to increase the length of the HS-SCCH Type 1 command. For example, if x nd,1 is used, x nd,1 can be set to x ord,4 for HS-SCCH order (HS-SCCH type 1). As another example, if (x tbspb, 4 , x tbspb, 5 , x tbspb, 6 ) is used, then the HS-SCCH order (HS-SCCH type 3) can be: x tbspb,1 , x tbspb,2 ,... , x tbspb,6 , and can be set to '1,1,1,x ord,4 ,x ord,5 ,x ord,6 . It should be understood that the reinterpreted bits can be mapped to any of the command types or commands.
在一個替代實施方式中,在配置WTRU用於多載波操作或多載波(MC)模式時,可以引入類型4這類新的HS-SCCH類型,以便傳送HS-SCCH命令。這種MC模式狀態可以從較高層用信號顯式通知(例如借助RRC信令)。HS-SCCH類型4可以被構造用於提供足夠的命令位元,以便在MC-HSPA系統中啟動/停用次級載波。 In an alternate embodiment, when configuring the WTRU for multi-carrier operation or multi-carrier (MC) mode, a new HS-SCCH type of type 4 may be introduced to transmit the HS-SCCH order. This MC mode state can be explicitly signaled from a higher layer (eg, via RRC signaling). The HS-SCCH Type 4 can be configured to provide sufficient command bits to enable/deactivate secondary carriers in the MC-HSPA system.
在這裏揭露的是用信號通知用於MC-HSPA的多個HS-SCCH命令的方法。由於HS-SCCH命令可以在任何載波上傳送,因此,多個服務胞元有可能用信號通知多個HS-SCCH命令,以便在具有例如4個DL和4個UL載波的MC-HSPA中基於每一載波(或是單一或預先配對載波,其中該載波可以是預先定義、預先規定或預先配置的)或是基於組來啟動/停用次級載波。不同的命令可以具有不同的命令類型和順序。該方法可以以控制信令負荷為代價而被應用於具有比4個DL和4個UL更多的載波的MC-HSPA。 Disclosed herein is a method of signaling multiple HS-SCCH commands for MC-HSPA. Since the HS-SCCH order can be transmitted on any carrier, it is possible for multiple serving cells to signal multiple HS-SCCH commands for each based on MC-HSPA with, for example, 4 DL and 4 UL carriers. A carrier (either a single or pre-paired carrier, where the carrier can be pre-defined, pre-defined or pre-configured) or a group based to enable/deactivate secondary carriers. Different commands can have different command types and sequences. The method can be applied to MC-HSPA with more carriers than 4 DL and 4 UL at the expense of control signaling load.
在另一個實施方式中,UTRAN傳送顯式L1信號,以便啟動或停用每一個載波或對每個載波分別進行啟動。 In another embodiment, the UTRAN transmits an explicit L1 signal to either activate or deactivate each carrier or initiate a separate start for each carrier.
在第一方法中,L1信號包括HS-SCCH命令,該命令可以傳送用於多個載波的啟動/停用命令。例如,該處理可以藉由將HS-SCCH命令類型位元中的某些或所有位元映射到指定載波來實施。該映射既可以由網路配置,也可以是隱式的。或者,這個HS-SCCH命令可以只傳送一個與目標載波位址結合的單一 啟動/停用命令。例如,該處理可以藉由如下處理實施:藉由保留HS-SCCH命令類型中的兩個位元來指示四個載波中的一個載波,以及藉由保留其他位元來指示載波啟動或停用。 In a first method, the L1 signal includes an HS-SCCH order that can transmit start/deactivate commands for multiple carriers. For example, the process can be implemented by mapping some or all of the bits in the HS-SCCH order type bits to a designated carrier. This mapping can be configured either by the network or implicitly. Alternatively, this HS-SCCH order can only transmit a single combined with the target carrier address. Start/deactivate command. For example, the process can be implemented by indicating one of the four carriers by retaining two bits in the HS-SCCH order type and indicating carrier activation or deactivation by retaining other bits.
在第二方法中,L1信號包括增強型專用通道(E-DCH)絕對授權通道(E-AGCH),其中該通道的位元欄位被重新解釋為是用信號通知同時啟動/停用多個載波。在第三方法中,L2和L3訊息被用於傳送啟動和停用顯式命令。 In the second method, the L1 signal includes an Enhanced Dedicated Channel (E-DCH) Absolute Grant Channel (E-AGCH), wherein the bit field of the channel is reinterpreted as signaling to simultaneously activate/deactivate multiple Carrier. In the third method, the L2 and L3 messages are used to transmit start and disable explicit commands.
在另一個實施方式中,載波的啟動或停用是在WTRU上由隱式規則觸發的。該觸發器可以基於下列參數中的任何一個單獨參數或是參數組合。例如,該參數可以是諸如總E-DCH緩衝狀態(TEBS)之類的緩衝狀態。它也可以是在錨定胞元接收的傳輸塊大小,在排程資訊(SI)中指示的功率餘量,或是用接收信號碼功率(RSCP)、接收信號強度指示符(RSSI)或其他類似測量指示或表示的接收信號功率。 In another embodiment, the initiation or deactivation of a carrier is triggered by an implicit rule on the WTRU. The trigger can be based on any of the following parameters or a combination of parameters. For example, the parameter can be a buffered state such as a total E-DCH buffer status (TEBS). It can also be the transport block size received in the anchor cell, the power headroom indicated in the Scheduling Information (SI), or the Received Signal Code Power (RSCP), Received Signal Strength Indicator (RSSI) or other Similar to the measured signal power indicated or indicated.
網路可以為用於啟動和停用的這些觸發器配置不同的臨界值。一旦觸發了載波啟動或停用,則WTRU可以單獨或者採用任何組合和順序來執行下列步驟中的任何一個。 The network can configure different thresholds for these triggers for startup and deactivation. Once carrier activation or deactivation is triggered, the WTRU may perform any of the following steps, either alone or in any combination and order.
WTRU可以使用L1、L2或L3來向網路傳遞載波啟動或停用指示訊息。WTRU可以將觸發載波啟動/停用的測量及/或原因包含為指示訊息的一部分。此外,WTRU還可以將所要啟動/停用的載波的索引包含為指示訊息的一部分。 The WTRU may use L1, L2, or L3 to deliver a carrier enable or disable indication message to the network. The WTRU may include measurements and/or causes of trigger carrier activation/deactivation as part of the indication message. In addition, the WTRU may also include an index of the carrier to be activated/deactivated as part of the indication message.
WTRU可以等待來自網路的顯式啟動或停用命令。在一個方法中,如果該指示是停用,則WTRU可以自發停用載波。在另一個方法中,如果該指示是載波啟動,則WTRU可以自發啟 動載波。 The WTRU may wait for an explicit start or disable command from the network. In one approach, if the indication is deactivated, the WTRU may spontaneously deactivate the carrier. In another method, if the indication is carrier initiated, the WTRU may initiate Dynamic carrier.
一旦停用了輔助載波,則可以停止用於該輔助載波的通道品質指示符(CQI)回饋報告。或者,CQI回饋報告可以以較低速率傳送。在另一個替代方案中,CQI回饋報告可以以較慢的速率並且使用L2信令傳送,例如在媒體存取通道(MAC)MAC-i標頭中傳送,此外它也可以在L3信令中而不是使用L1高速專用實體控制通道(HS-DPCCH)來傳送。一旦啟動了輔助載波,則可以恢復CQI回饋。這些CQI活動適用於這裏揭露的所有實施方式。 Once the secondary carrier is deactivated, the channel quality indicator (CQI) feedback report for the secondary carrier can be stopped. Alternatively, the CQI feedback report can be transmitted at a lower rate. In another alternative, the CQI feedback report can be transmitted at a slower rate and using L2 signaling, such as in a Media Access Channel (MAC) MAC-i header, and it can also be in L3 signaling. It is not transmitted using the L1 High Speed Dedicated Entity Control Channel (HS-DPCCH). Once the secondary carrier is activated, the CQI feedback can be resumed. These CQI activities apply to all of the embodiments disclosed herein.
當在同一頻段中為多載波操作配置了多個載波時,這些載波既可以是相鄰的,也可以是不相鄰的。相鄰載波可以用特定技術所需要的頻寬間隔。例如在WCDMA FDD中,每一個載波可以間隔5MHz。因此,相鄰載波的載波頻率間隔5MHz。通常,在配置了N個相鄰載波時,相鄰載波將會佔用N倍於5MHz的聚合且連續的頻寬。 When multiple carriers are configured for multi-carrier operation in the same frequency band, these carriers may be adjacent or non-adjacent. Adjacent carriers can be spaced by the bandwidth required by a particular technique. For example, in WCDMA FDD, each carrier can be separated by 5 MHz. Therefore, the carrier frequencies of adjacent carriers are separated by 5 MHz. Generally, when N adjacent carriers are configured, adjacent carriers will occupy an aggregated and continuous bandwidth of N times 5 MHz.
由於硬體限制,某些WTRU很難同時接收並成功解調來自相同頻段中的非相鄰載波的信號。硬體限制有可能包括與濾波這些信號有關的限制。對多載波操作來說,當有兩個以上的載波時,有可能需要限制WTRU的載波啟動/停用狀態,以便保持或確保連續的啟動頻譜。 Due to hardware limitations, it is difficult for some WTRUs to simultaneously receive and successfully demodulate signals from non-adjacent carriers in the same frequency band. Hardware limitations may include limitations related to filtering these signals. For multi-carrier operation, when there are more than two carriers, it may be necessary to limit the carrier start/deactivate state of the WTRU in order to maintain or ensure a continuous start spectrum.
當WTRU不支持在一個頻段內部具有不相鄰載波時,RRC可能不會允許在該頻段內部配置非相鄰載波。同樣,節點B未必被配置用於或者允許使用那些有可能導致從一個或多個已配置載波的停用處理中產生非相鄰載波的HS-SCCH命令。 When the WTRU does not support having non-adjacent carriers within one frequency band, RRC may not allow non-adjacent carriers to be configured within the frequency band. Likewise, Node B is not necessarily configured or allowed to use HS-SCCH commands that may result in non-adjacent carriers from deactivation processing of one or more configured carriers.
這裏描述的HS-SCCH命令方案同時顧及了不相鄰和相鄰載波的情況。在限制了僅僅啟動相鄰載波的情況下,這裏揭露的方法也可以用於啟動和停用多個載波。該處理可以藉由保留任何導致產生不相鄰載波的HS-SCCH命令(也就是說,這些HS-SCCH命令有可能沒有被節點B使用或通知)來完成。例如在具有4個DL和1個UL載波的MC-HSDPA的範例中,在不喪失一般性的情況下,如果假設4個DL相鄰載波按照DL0、DL1、DL2和DL3的順序鄰接來配置這些載波,那麼,由於在假設沒有停用DL0/UL0的時候可以僅僅啟動/停用DL3,因此,在這裏可以保留表1中的命令“0xx”(“x”可以是0或1)。同樣,在具有上述相鄰載波限制的情況下,在這裏揭露的用於為載波啟動/停用設計HS-SCCH命令的方法也可用於進一步最佳化載波的啟動/停用。 The HS-SCCH command scheme described herein takes into account both non-adjacent and adjacent carriers. The method disclosed herein can also be used to initiate and deactivate multiple carriers without limiting the activation of only adjacent carriers. This processing can be accomplished by retaining any HS-SCCH commands that result in non-adjacent carriers (that is, these HS-SCCH commands may not be used or notified by Node B). For example, in the example of MC-HSDPA having 4 DLs and 1 UL carrier, if no generality is lost, if four DL adjacent carriers are assumed to be adjacent in the order of DL0, DL1, DL2, and DL3, these are configured. Carrier, then, since DL3 can be started/deactivated only on the assumption that DL0/UL0 is not deactivated, the command "0xx" in Table 1 can be retained here ("x" can be 0 or 1). Also, in the case of having the adjacent carrier restrictions described above, the method disclosed herein for designing HS-SCCH commands for carrier start/deactivation can also be used to further optimize the start/deactivation of carriers.
更進一步,在這裏揭露了用於描述在接收導致產生不支持的載波啟動/停用配置的配置訊息時的WTRU行為的方法。在一個示例中,WTRU接收一個引起無效載波啟動/停用配置的HS-SCCH命令。在接收引起無效載波啟動/停用配置的HS-SCCH命令時,WTRU可以執行下列操作中的任何一個或是其組合:WTRU可以忽略HS-SCCH命令,並且維持其目前配置;WTRU可以忽略HS-SCCH命令,並且禁用具有不相鄰載波的頻段中的所有輔助載波;WTRU可以在HS-DPCCH上HS-SCCH命令;WTRU可以在HS-DPCCH上確認HS-SCCH命令;WTRU可以在HS-DPCCH上對HS-SCCH命令做出否定確認;或者WTRU在HS-DPCCH(DTX)上不確認HS-SCCH或是對其做出否定確認。 Still further, a method for describing WTRU behavior when receiving a configuration message that results in an unsupported carrier start/deactivation configuration is disclosed herein. In one example, the WTRU receives an HS-SCCH order that causes an invalid carrier start/deactivate configuration. Upon receiving an HS-SCCH order that causes an invalid carrier start/deactivate configuration, the WTRU may perform either or a combination of the following: the WTRU may ignore the HS-SCCH order and maintain its current configuration; the WTRU may ignore the HS- SCCH order, and disable all secondary carriers in bands with non-adjacent carriers; WTRU may HS-SCCH order on HS-DPCCH; WTRU may acknowledge HS-SCCH order on HS-DPCCH; WTRU may be on HS-DPCCH A negative acknowledgment is made to the HS-SCCH order; or the WTRU does not acknowledge or negatively acknowledge the HS-SCCH on the HS-DPCCH (DTX).
在這裏揭露了用於啟動/停用DRX和DTX以及用於處理DRX和DTX的操作的實施方式。在下文中描述了用於為DRX操作配置WTRU的方法。該WTRU可以由網路使用L3訊息傳遞來進行配置。 Embodiments for enabling/disabling DRX and DTX and for handling DRX and DTX operations are disclosed herein. A method for configuring a WTRU for DRX operation is described below. The WTRU can be configured by the network using L3 messaging.
在第一實施方式中,網路使用一組DRX參數來配置WTRU,並且WTRU將這些DRX參數隱式應用於所有下鏈載波。在另一個實施方式中,網路在每一個頻段上配置一組DRX參數,並且WTRU將相同的參數應用於相同波段中的所有下鏈載波。在另一個實施方式中,網路為每一個載波單獨配置一組DRX參數。在更進一步的實施方式,網路為每一個錨定載波配置一組DRX參數。在此實施方式中,用於輔助載波的DRX參數與用於相關聯的錨定載波的參數是相同的。在這裏揭露的實施方式中,如果WTRU具有一個以上的接收鏈路,那麼網路可以配置第二組參數。 In a first embodiment, the network configures the WTRU using a set of DRX parameters, and the WTRU implicitly applies these DRX parameters to all downlink carriers. In another embodiment, the network configures a set of DRX parameters on each frequency band and the WTRU applies the same parameters to all downlink carriers in the same band. In another embodiment, the network separately configures a set of DRX parameters for each carrier. In still further embodiments, the network configures a set of DRX parameters for each anchor carrier. In this embodiment, the DRX parameters for the secondary carrier are the same as the parameters for the associated anchor carrier. In the embodiments disclosed herein, if the WTRU has more than one receive link, the network can configure a second set of parameters.
在另一個實施方式中,網路為每一組下鏈載波配置一組DRX參數,其中同一組內部的所有載波都使用了相同的DRX參數。這些組既可以在建立/重新配置無線電承載時藉由無線電資源控制(RRC)信令預先配置,也可以在WTRU上預先配置。或者,在這裏可以定義一組下鏈載波,以此作為所有那些為WTRU分配了相同無線電網路臨時識別碼的載波。先前揭的分組方法同樣可以用於確定恰當的組。 In another embodiment, the network configures a set of DRX parameters for each set of downlink carriers, wherein all carriers within the same group use the same DRX parameters. These groups can be pre-configured either by Radio Resource Control (RRC) signaling or pre-configured on the WTRU when establishing/reconfiguring a radio bearer. Alternatively, a set of downlink carriers can be defined here as all carriers that have assigned the same radio network temporary identification code to the WTRU. The previously disclosed grouping method can also be used to determine the appropriate group.
在這裏揭露了與初始化時的DRX狀態相關的實施方式。在一個實施方式中,在配置下鏈載波時,可以停用用於所有下鏈載波的DRX。或者,網路可以預先配置DRX狀態,該狀態可 以應用於所有下鏈載波或是這些載波的一個子集或組。在另一個替代方案中,網路可以單獨為每一個下鏈載波配置DRX狀態。 Embodiments related to the DRX state at initialization are disclosed herein. In one embodiment, DRX for all downlink carriers may be deactivated when configuring the downlink carrier. Alternatively, the network can be pre-configured with a DRX state, which can be To apply to all downlink carriers or a subset or group of these carriers. In another alternative, the network can configure the DRX state for each of the downlink carriers separately.
在這裏揭露了用於在WTRU上觸發DRX啟動和停用的實施方式。在一個實施方式中,網路可以顯式通知WTRU啟動或停用DRX。此啟動或停用訊息可以針對一個特定載波或一組載波。為了顯式通知DRX啟動和停用,網路可以用DRX啟動/停用替換載波啟動/停用,以便使用上述載波啟動和停用方法中的任何一種。 Embodiments for triggering DRX initiation and deactivation on a WTRU are disclosed herein. In one embodiment, the network may explicitly inform the WTRU to initiate or deactivate DRX. This start or stop message can be for a specific carrier or a group of carriers. In order to explicitly inform the DRX to start and deactivate, the network can initiate/disable alternate carrier activation/deactivation with DRX to use any of the carrier start and stop methods described above.
在另一個實施方式中,WTRU可以隱式地為載波的一個子集或組啟動或停用DRX。例如,該啟動或停用觸發器可以基於下列測量中的任何一個或是其組合。一個測量可以是指定時段的下鏈活動。另一個測量可以是指定時段的下鏈資料速率。再一個測量可以是所報告的CQI。別的測量還可以是無線電功率測量,例如公共導頻通道(CPICH)測量、RSCP、RSSI等等。這些測量可以在一個或幾個載波上執行,並且可以取平均值。 In another embodiment, the WTRU may implicitly initiate or deactivate DRX for a subset or group of carriers. For example, the activation or deactivation trigger can be based on any one of the following measurements or a combination thereof. A measurement can be a down-chain activity for a specified time period. Another measurement can be the downlink data rate for a given time period. Another measurement can be the reported CQI. Other measurements may also be radio power measurements such as Common Pilot Channel (CPICH) measurements, RSCP, RSSI, and the like. These measurements can be performed on one or several carriers and can be averaged.
網路可以根據一個或多個上述測量來配置一個用於進入DRX的臨界值(DRX-in)以及一個用於離開DRX的臨界值(DRX-out)。當DRX沒有活動並且實際測量達到了DRX-in臨界值時,WTRU可以在相關聯的載波或載波組上應用DRX。同樣,當DRX啟動並且實際測量達到DRX-out臨界值時,WTRU可以在相關聯的載波或載波組上停用DRX。 The network may configure a threshold for entering DRX (DRX-in) and a threshold for leaving DRX (DRX-out) based on one or more of the above measurements. When DRX is not active and the actual measurement reaches the DRX-in threshold, the WTRU may apply DRX on the associated carrier or carrier group. Likewise, when DRX is initiated and the actual measurement reaches the DRX-out threshold, the WTRU may deactivate DRX on the associated carrier or carrier group.
為了隱式啟動和停用DRX,WTRU可以向網路通知狀態改變。因此,當DRX啟動時,WTRU可以發送一個訊息來向網路告知狀態改變。該訊息可以包括下列資訊中的任何一個或是其 組合:相關的載波索引或引用;觸發狀態改變的測量值;變化原因;啟動時間;或是新的狀態。 To implicitly initiate and deactivate DRX, the WTRU may notify the network of a status change. Thus, when DRX is initiated, the WTRU may send a message to inform the network of a status change. The message may include any of the following information or Combination: the relevant carrier index or reference; the measured value of the trigger status change; the cause of the change; the start time; or the new status.
在這裏揭露了與載波啟動時的DRX操作有關的WTRU活動。一旦WTRU啟動了一個或多個載波,WTRU可以執行下列活動中的任何一個或是其組合。在一個方法中,WTRU可以將載波的DRX狀態恢復到其在停用之前的狀態。在另一個方法中,WTRU可以將載波的DRX狀態配置為與錨定載波相同的狀態。在另一個方法中,WTRU可以將載波的DRX狀態配置為與相同頻段中的錨定載波相同的狀態。在另一個方法中,WTRU可以將載波的DRX狀態配置為與相同頻段中的其他載波相同的狀態。在另一個方法中,WTRU可以將DRX狀態配置為“活動”。在另一個方法中,WTRU可以將DRX狀態配置為“不活動”。在另一個實施方式中,WTRU可以停用所有載波的DRX。在另一個方法中,WTRU可以停用與新啟動的載波處於相同波段的所有載波的DRX。在另一個方法中,WTRU可以為所有載波啟動DRX。在進一步的方法中,WRTU可以為與新啟動的載波處於相同頻段的所有載波停用DRX。 The WTRU activity associated with DRX operation at carrier startup is disclosed herein. Once the WTRU has initiated one or more carriers, the WTRU may perform any one of the following activities or a combination thereof. In one approach, the WTRU may restore the DRX state of the carrier to its state prior to deactivation. In another approach, the WTRU may configure the DRX state of the carrier to be in the same state as the anchor carrier. In another approach, the WTRU may configure the DRX state of the carrier to be the same state as the anchor carrier in the same frequency band. In another approach, the WTRU may configure the DRX state of the carrier to be the same state as the other carriers in the same frequency band. In another approach, the WTRU may configure the DRX state to be "active." In another approach, the WTRU may configure the DRX state to be "inactive." In another embodiment, the WTRU may deactivate DRX for all carriers. In another approach, the WTRU may deactivate DRX for all carriers in the same band as the newly activated carrier. In another approach, the WTRU may initiate DRX for all carriers. In a further approach, the WRTU may disable DRX for all carriers in the same frequency band as the newly activated carrier.
在這裏揭露了與載波停用時的DRX操作有關的WTRU活動。一旦WTRU停用了一個或多個載波,則WTRU可以執行下列活動中的任何一個或是其組合。在一個方法中,WTUR可以為所有剩餘活動載波或其中的一組剩餘活動載波啟動DRX。例如,WTRU將載波停用解釋為低活動狀態轉變或是進入低功率模式。在另一個實施方式中,WTRU可以為所有剩餘活動載波或其中的一組剩餘活動載波停用DRX。例如,WTRU可以將載波停用解釋為是在不改變訊務量活動的情況下節約功率。 The WTRU activity associated with DRX operation at carrier deactivation is disclosed herein. Once the WTRU has deactivated one or more carriers, the WTRU may perform any one of the following activities or a combination thereof. In one approach, the WTUR can initiate DRX for all remaining active carriers or a set of remaining active carriers. For example, the WTRU interprets carrier deactivation as a low active state transition or into a low power mode. In another embodiment, the WTRU may deactivate DRX for all remaining active carriers or a group of remaining active carriers. For example, the WTRU may interpret carrier deactivation as saving power without changing traffic activity.
在這裏揭露了用於在多載波環境中處理HSDPA中的確認和否定確認(ACK/NACK)回饋的實施方式。在目前系統中,具有多輸入多輸入(MIMO)的HSDPA或DC-HSDPA中的確認和否定確認(ACK/NACK)回饋可以包括在HS-DPCCH的混合自動重複請求(HARQ)HARQ-ACK欄位上傳送預定簽名。在此方法中,ACK/NACK/DTX事件的每一種可能組合都具有一個簽名。 Embodiments for processing acknowledgement and negative acknowledgement (ACK/NACK) feedback in HSDPA in a multi-carrier environment are disclosed herein. In current systems, acknowledgment and negative acknowledgment (ACK/NACK) feedback in HSDPA or DC-HSDPA with Multiple Input Multiple Input (MIMO) may be included in the hybrid automatic repeat request (HARQ) HARQ-ACK field of the HS-DPCCH The scheduled signature is transmitted on. In this method, each possible combination of ACK/NACK/DTX events has a signature.
在一個實施方式中,ACK/NACK資訊是用第6圖所示的調變簽名疊加(superposition)傳送的。每一個已配置載波都可以具有一個簽名。該N個簽名可以是正交的。ACK-NACK x輸入可以採用值+1、-1和0,以便分別表示ACK、NACK和DTX。或者,ACK和NACK的值可以反過來。在另一個替代方案中,ACK和NACK的值可以被配置為不同的值,而不是單位值。這種配置同樣可以由UTRAN用信號通知。 In one embodiment, the ACK/NACK information is transmitted using the modulation signature superposition shown in FIG. Each configured carrier can have a signature. The N signatures can be orthogonal. The ACK-NACK x input can take the values +1, -1, and 0 to represent ACK, NACK, and DTX, respectively. Alternatively, the values of ACK and NACK can be reversed. In another alternative, the values of ACK and NACK can be configured to different values instead of unit values. This configuration can also be signaled by the UTRAN.
從加總所有傳送簽名得到的結果可以用一個因數△MC-ACK-NACK進行縮放。該因數既可以是預定的,也可以由UTRAN配置。或者,該縮放因數可以取決於所傳送的ACK/NACK的數量。當同時存在多個簽名時,這時可以為ACK/NACK分配更多功率,以便補償在信號中引入的潛在的附加失真。 The result from summing all the transmitted signatures can be scaled by a factor Δ MC-ACK-NACK . This factor can be either predetermined or configured by the UTRAN. Alternatively, the scaling factor may depend on the number of ACK/NACKs transmitted. When multiple signatures are present at the same time, more power can be allocated for the ACK/NACK in order to compensate for the potential additional distortion introduced in the signal.
在替代實施方式中,縮放因數△MC-ACK-NACK的值可以藉由預定規則並根據所傳送的非零ACK-NACK值Nnz的數量來確定。例如對所傳送的每一個附加的非零ACK-NACK值來說,在縮放因數中將會添加一個附加的△nz(以dB為單位),其中△nz是由UTRAN用信號通知或是在規範中預先配置的。 In an alternative embodiment, the value of the scaling factor Δ MC-ACK-NACK may be determined by a predetermined rule and based on the number of non-zero ACK-NACK values Nnz transmitted. For example, for each additional non-zero ACK-NACK value transmitted, an additional Δnz (in dB) will be added to the scaling factor, where Δnz is signaled by UTRAN or is in specification Pre-configured.
在第二替代實施方式中,將縮放因數映射為非零ACK-NACK數量的查找表既可以是預先定義的,也可以由UTRAN用信號通知。 In a second alternative embodiment, the lookup table that maps the scaling factor to a non-zero ACK-NACK number may be either predefined or signaled by the UTRAN.
雖然這裏針對多載波啟動/停用和操作而揭露的實施方式是對照多載波高速封包存取(HSPA)以及高速下鏈封包存取(HSDPA)描述的,但是這些實施方式同樣適用於除了這些載波配置之外的系統以及其他的多載波系統。 Although the embodiments disclosed herein for multi-carrier enable/disable and operation are described in relation to Multi-Carrier High Speed Packet Access (HSPA) and High Speed Downlink Packet Access (HSDPA), these embodiments are equally applicable to these carriers. Systems other than configuration and other multi-carrier systems.
雖然上述內容是對照HSPA和HSDPA揭露的,但其同樣適用於任何無線環境。例如,第7圖顯示了一個長期演進(LTE)無線通訊系統/存取網路700,其中該網路包括演進型通用陸地存取網路(E-UTRAN)705。E-UTRAN 705包括WTRU 710和若干個演進型節點B(eNB)720。WTRU 710與eNB 720通訊。eNB 720彼此使用X2介面連接。每一個eNB 720都經由S1介面與行動管理實體(MME)/服務閘道(S-GW)730連接。雖然在第7圖中顯示的是單一WTRU 710和三個eNB 720,但是很明顯,在無線通訊系統存取網路700中可以包含無線和有線裝置的任何組合。 While the above is disclosed in relation to HSPA and HSDPA, it is equally applicable to any wireless environment. For example, Figure 7 shows a Long Term Evolution (LTE) wireless communication system/access network 700, where the network includes an Evolved Universal Terrestrial Access Network (E-UTRAN) 705. E-UTRAN 705 includes a WTRU 710 and a number of evolved Node Bs (eNBs) 720. The WTRU 710 is in communication with the eNB 720. The eNBs 720 are connected to each other using an X2 interface.

Although a single WTRU 710 and three eNBs 720 are shown in FIG. 7, it will be apparent that any combination of wireless and wired devices can be included in the wireless communication system access network 700.

The processor 816 is configured To enhance the security of direct link communication.
