Abstract
Description
本發明係有關於通訊。 The invention relates to communication.
3GPP LTE-A(長期演進技術升級版)包含用以支援載波聚合之主小區(PCell)及次小區(SCell)的概念。在LTE-A中引進載波聚合,以便提供增加的頻寬及藉此提供增加的位元率。每一聚合載波稱為成分載波(CC)或另外稱為小區(cell)或服務小區(serving cell)。當實施載波聚合時,提供數個服務小區,每一成分載波有一服務小區。該服務小區之涵蓋範圍可能例如因所經歷的路徑損失而有所不同。該等服務小區中之一稱為一主服務小區,其使用一主成分載波(DL及UL PCC)。其它成分載波稱為次成分載波(DL及UL SCC),其供次服務小區使用。 3GPP LTE-A (Long Term Evolution Technology Upgrade) includes the concept of a primary cell (PCell) and a secondary cell (SCell) to support carrier aggregation. Carrier aggregation is introduced in LTE-A to provide increased bandwidth and thereby provide increased bit rate. Each aggregated carrier is referred to as a component carrier (CC) or otherwise referred to as a cell or a serving cell. When carrier aggregation is implemented, several serving cells are provided, and each component carrier has a serving cell. The coverage of the serving cell may vary, for example, due to the path loss experienced. One of the serving cells is referred to as a primary serving cell, which uses a primary component carrier (DL and UL PCC). The other component carriers are called secondary component carriers (DL and UL SCC), which are used by the secondary serving cell.

A single feature of a different embodiment may also be combined to provide other embodiments. In addition, it should be understood that the words "comprise" and "comprising" are not used to limit that the described embodiments are only those that have been described, and such embodiments may also include features not specifically mentioned. structure.
第1圖描述可用於本發明之實施例的實施之無線通訊方案的實例。參考第1圖,一蜂巢式通訊系統可以包括一無線電接取網路,其包括配置成用以在一預定地理區域中提供無線電涵蓋範圍之基地台。該等基地台可以包括配置成用以在一例如橫跨數平方英里之相對大區域內提供終端裝置(UE)106無線電涵蓋範圍之大型基地台(eNB)102。在需要提高容量之人口稠密熱點中,配置小型基地台(eNB)100,以提供終端裝置(UE)104高的資料傳輸率服務。這樣的小型基地台可以稱為微型基地台、特微型基地台或毫微微基地台。該等小型基地台通常具有明顯比該大型基地台102小之涵蓋範圍。該蜂巢式通訊系統可以依據第三代行動通訊合作計劃(3GPP)長期演進技術(LTE)升級版或它的進化版(例如,5G)之規格操作。 Figure 1 depicts an example of a wireless communication scheme that can be used in the implementation of embodiments of the present invention. Referring to FIG. 1, a cellular communication system can include a radio access network including a base station configured to provide radio coverage in a predetermined geographic area. The base stations may include a large base station (eNB) 102 configured to provide radio coverage of a terminal device (UE) 106 over a relatively large area, such as across a few square miles. In a densely populated hotspot where capacity is required to be increased, a small base station (eNB) 100 is arranged to provide a high data rate service of the terminal device (UE) 104. Such a small base station can be called a micro base station, a special micro base station or a femto base station. These small base stations typically have a significantly smaller coverage than the large base station 102. The cellular communication system can operate in accordance with the 3rd Generation Partnership Project (LTE) Long Term Evolution (LTE) upgrade or its evolutionary version (eg, 5G).
當實施載波聚合時,一個以上的成分載波供UE使用。這些成分載波可以在相同位置中(例如,在該大型基地台中)或在不同位置中(例如,一個成分載波在該大型基地台中及其它成分載波則在小型基地台中)。可以藉由在相同操作頻帶內使用連續成分載波,配置載波聚合。上述可能例如因經營商頻率分配方案(operator frequency allocation scenarios)而成為不可能。非連續分配可能是同頻的(intra-band),亦即,該等成分載波屬於相同操作頻帶,但是其間具有間隙,或者它可能是跨頻的(inter-band),其中該等成分載波屬於不同操作頻帶。第2圖描述載波聚合。關於排程,載波聚合具有兩種主 要備選方案,當接收許可時,在相同載波上安排資源(亦即,自排程),或者可以使用跨載波排程,其中在一不同載波上接收包含有一載波之排程許可的下行鏈路控制資訊。對於跨載波排程,一排程小區亦載運其它小區之排程許可,該等其它小區因而表示為(跨載波)排定小區。第3圖描述自排程,以及第4圖描述跨載波排程。 When carrier aggregation is implemented, more than one component carrier is used by the UE. These component carriers may be in the same location (e.g., in the large base station) or in different locations (e.g., one component carrier is in the large base station and other component carriers are in the small base station). Carrier aggregation can be configured by using consecutive component carriers within the same operating band. This may be impossible, for example, due to operator frequency allocation scenarios. The discontinuous allocation may be intra-band, that is, the component carriers belong to the same operating band, but have gaps therebetween, or it may be inter-band, where the component carriers belong to Different operating bands. Figure 2 depicts carrier aggregation. Regarding scheduling, carrier aggregation has two main types. To be an alternative, when receiving a grant, resources are scheduled on the same carrier (ie, self-scheduled), or cross-carrier scheduling can be used, where a downlink containing a carrier's scheduling grant is received on a different carrier. Road control information. For cross-carrier scheduling, a scheduled cell also carries scheduling grants for other cells, which are thus represented as (cross-carrier) scheduled cells. Figure 3 depicts the self-scheduled, and Figure 4 depicts the cross-carrier scheduling.
依據Rel-10之跨載波排程在一UL/DL排程許可中使用一欄位,其表示為載波指示欄位(CIF)。在Rel-10中,CIF受限為3個位元,此如LTE規格所支援,足以使高達5個成分載波之跨載波排程成為可能。該載波指示欄位係排程UL/DL許可程序之一部分,以及在下行鏈路控制資訊(DCI)內傳送該載波指示欄位。 A cross-carrier schedule based on Rel-10 uses a field in a UL/DL schedule grant, which is represented as a Carrier Indicator Field (CIF). In Rel-10, the CIF is limited to 3 bits, which is supported by the LTE specification, which is sufficient to enable cross-carrier scheduling of up to 5 component carriers. The carrier indication field is part of a scheduled UL/DL grant procedure and the carrier indication field is transmitted within downlink control information (DCI).
載波聚合之跨載波排程係UE能力。分別針對每一配置成分載波,配置用於UE之載波聚合的跨載波排程。 The cross-carrier scheduling of carrier aggregation is UE capability. A cross-carrier scheduling for carrier aggregation of the UE is configured for each configured component carrier, respectively.
在3GPP LTE Rel-10中,DCI中所載運之CIF受限為3個位元,以及CIF之數值等於一服務小區索引。該CIF值定義該排程UL/DL許可相關之載波,以及該CIF值亦影響UE所正在搜尋之下行鏈路控制通道使用者特定搜尋空間位置。依該CIF值(0...7)而定之個別搜尋空間資訊可以是如下。根據搜尋空間定義用於監控之候選實體下行鏈路控制通道(PDCCH)集合,其中以一候選PDCCH集合定義處於一聚合等級之搜尋空間。針對監控PDCCH之每一服務小區,定義對應於該搜尋空間之候選PDCCH的控制通道元件(CCE)。可以將下面列入考量: 一共同搜尋空間、一PDCCH(或增強型實體下行鏈路控制通道(EPDCCH))UE特定搜尋空間、是否監控的UE配置有該載波指示欄位、監控PDCCH/EPDCCH之服務小區及/或在既定搜尋空間中監控之候選PDCCH/EPDCCH之數目。該載波指示欄位值相同於該服務小區索引。 In 3GPP LTE Rel-10, the CIF carried in the DCI is limited to 3 bits, and the value of the CIF is equal to a serving cell index. The CIF value defines the carrier associated with the scheduled UL/DL grant, and the CIF value also affects the user-specific search space location of the downlink control channel under which the UE is searching. The individual search space information according to the CIF value (0...7) may be as follows. A candidate entity downlink control channel (PDCCH) set for monitoring is defined according to the search space, wherein a search space at an aggregation level is defined by a candidate PDCCH set. For each serving cell monitoring the PDCCH, a Control Channel Element (CCE) corresponding to the candidate PDCCH of the search space is defined. The following can be considered: a common search space, a PDCCH (or Enhanced Physical Downlink Control Channel (EPDCCH)) UE-specific search space, whether the monitored UE is configured with the carrier indication field, the serving cell monitoring the PDCCH/EPDCCH, and/or The number of candidate PDCCH/EPDCCHs monitored in the search space. The carrier indicates that the field value is the same as the serving cell index.
該跨載波排程之配置的定義如下。在PhysicalConfigDedicated(PCell配置)中之cif-Presence-r10表示是否CIF存在於PCell之PDCCH下行鏈路控制資訊(DCI)中。一CIF值0表示PCell,同時可以以一ServCellIndex參數定址另一SCell,亦即,該CIF值相同於該ServCellIndex參數。於是,每一SCell可以配置成具有該跨載波排程做為SCell附加或修改之一部分。藉由為PhysicalConfigDedicatedSCell參數之一部分的CrossCarrierSchedulingConfig參數來實施具有該跨載波排程做為SCell附加或修改之一部分的SCell之配置。 The configuration of this cross-carrier scheduling is defined as follows. The cif-Presence-r10 in the PhysicalConfigDedicated indicates whether the CIF exists in the PDCCH Downlink Control Information (DCI) of the PCell. A CIF value of 0 indicates a PCell, and another SCell can be addressed with a ServCellIndex parameter, that is, the CIF value is the same as the ServCellIndex parameter. Thus, each SCell can be configured to have this cross-carrier schedule as part of the SCell addition or modification. The configuration of the SCell with the cross-carrier scheduling as part of the SCell addition or modification is implemented by the CrossCarrierSchedulingConfig parameter, which is part of the PhysicalConfigDedicatedSCell parameter.
支援有陳述可安排高達32個成分載波之有關載波聚合增強的Rel-13。規定使下行鏈路(DL)及上行鏈路(UL)之高達32個成分載波的LTE載波聚合成為可能之機制,其如果有的話,包括針對高達32個成分載波之DL控制發信的增強(包括自排程及跨載波排程)。 Support for Rel-13 with respect to carrier aggregation enhancements that can be scheduled to schedule up to 32 component carriers. Provision of a mechanism for LTE carrier aggregation of up to 32 component carriers of the downlink (DL) and uplink (UL), if any, including enhancements to DL control signaling for up to 32 component carriers (including self-scheduled and cross-carrier scheduling).
根據該CrossCarrierSchedulingConfig參數,與Rel-10 LTE載波聚合一起被規定之一SchedulingCellInfo參數指示跨載波排程是否是啟用的。表示「自身」之該SchedulingCellInfo參數意味著 SCell傳送它自身的PDCCH,亦即,沒有啟用該跨載波排程。可以藉由cif-Presence-10來表示SCell是否為一可交互安排另一小區之排程小區(在Rel-10中亦可使SCell成為可交互安排另一SCell之排程小區)。另一方面,如果啟用跨載波排程(亦即,以另一小區來交互安排SCell),則該SchedulingCellInfo參數表示「其它」,此意味著一些「其它」服務小區傳送PDCCH DCI。 According to the CrossCarrierSchedulingConfig parameter, together with Rel-10 LTE carrier aggregation, one of the SchedulingCellInfo parameters is specified to indicate whether cross-carrier scheduling is enabled. The "SchedulingCellInfo parameter" indicating "self" means The SCell transmits its own PDCCH, ie, the cross-carrier scheduling is not enabled. It can be indicated by cif-Presence-10 whether the SCell is a scheduled cell that can interactively arrange another cell (in the Rel-10, the SCell can also be made into a scheduled cell that can interactively arrange another SCell). On the other hand, if cross-carrier scheduling is enabled (i.e., the SCell is alternately arranged with another cell), the SchedulingCellInfo parameter indicates "other", which means that some "other" serving cells transmit the PDCCH DCI.
一SchedulingCellId參數通知UE哪一個小區發信告知對考慮中之SCell的下行鏈路分配及上行鏈路許可。延伸此操作至32個成分載波(亦即,32個服務小區),其從UE的觀點來說,此意味著服務小區索引需要從[0,...,7]增加至[0,...,31]。此亦可能影響該跨載波排程操作。 A SchedulingCellId parameter informs the UE which cell to signal the downlink assignment and uplink grant for the SCell under consideration. This operation is extended to 32 component carriers (ie, 32 serving cells), which means that from the UE's point of view, this means that the serving cell index needs to be increased from [0,...,7] to [0,.. ., 31]. This may also affect the cross-carrier scheduling operation.
可以藉由將該CIF長度從3位元增加至5位元,擴展跨載波排程原理,以便使高達32個成分載波之跨載波排程成為可能。然而,上述需要較大的DCI格式,因而有較高的可能性造成DCI之漏失偵測(亦即,在相同聚合等級下有較高的編碼速率)。此外,會有較高的可能性具有相同大小之DCI及需要額外地在DCI之末端添加位元(以防止不定性(ambiguity)),此進一步增加DCI區塊錯誤率(block error rate)。如果兩個DCI具有相同的大小,則可能在末端添加零,以產生不同的大小。 The cross-carrier scheduling principle can be extended by increasing the CIF length from 3 bits to 5 bits to enable cross-carrier scheduling of up to 32 component carriers. However, the above requires a larger DCI format, and thus there is a higher possibility of DCI loss detection (i.e., a higher coding rate at the same aggregation level). In addition, there is a higher probability of having the same size of DCI and the need to additionally add bits at the end of the DCI (to prevent ambiguity), which further increases the DCI block error rate. If the two DCIs have the same size, it is possible to add zeros at the end to produce different sizes.
現在讓我們根據第5圖來描述載波聚合之實施例。第5圖係描述在該蜂巢式通訊系統之網路元件間傳遞跨載波排程參數之方法的傳訊圖。該網路元件可能 是網路節點、接取節點、基地台、終端裝置、伺服器電腦或主機電腦。例如,該伺服器或主機電腦可以產生一可讓該主機電腦與該終端裝置通信之虛擬網路。通常,虛擬網路建構可能包含將硬體及軟體網路資源與網路功能組合成單一以軟體為基礎的管理實體(虛擬網路)之程序。在另一實施例中,該網路節點可能是一終端裝置。網路虛擬化可能包含平台虛擬化,其常常與資源虛擬化結合。網路虛擬化可歸類為將許多網路或網路之部分結合成為該伺服器或主機電腦的外部虛擬網路建構。外部網路虛擬化的目標是最佳網路共享。另一類型是提供類網路功能至單一系統上之軟體容器(software containers)的內部虛擬網路建構。虛擬網路建構亦可用以測試該終端裝置。 Let us now describe an embodiment of carrier aggregation in accordance with FIG. Figure 5 is a diagram depicting a method of communicating cross-carrier scheduling parameters between network elements of the cellular communication system. The network component may It is a network node, an access node, a base station, a terminal device, a server computer, or a host computer. For example, the server or host computer can generate a virtual network that allows the host computer to communicate with the terminal device. In general, virtual network construction may involve the process of combining hardware and software network resources and network functions into a single software-based management entity (virtual network). In another embodiment, the network node may be a terminal device. Network virtualization may involve platform virtualization, which is often combined with resource virtualization. Network virtualization can be categorized as the integration of many networks or portions of the network into the external virtual network of the server or host computer. The goal of external network virtualization is optimal network sharing. Another type is the internal virtual network construction that provides network-like functionality to software containers on a single system. The virtual network construction can also be used to test the terminal device.
參考第5圖,在項目501中,一網路節點針對一終端裝置決定載波聚合之配置且至少一小區配置成以跨載波排程來安排。在一實施例中,該配置包括用於載波聚合之8個以上的服務小區。然而,本發明之實施例並非侷限於此用以做為範例之數目。在一實施例中,該網路節點可以決定以跨載波排程安排之該配置服務小區的服務小區索引與一排程小區特定載波指示欄位值間之映射。 Referring to FIG. 5, in item 501, a network node determines a carrier aggregation configuration for a terminal device and at least one cell is configured to be scheduled in a cross-carrier schedule. In an embodiment, the configuration includes more than eight serving cells for carrier aggregation. However, the embodiments of the present invention are not limited to the number used as an example. In an embodiment, the network node may determine a mapping between a serving cell index of the configured serving cell and a scheduled cell specific carrier indication field value arranged in a cross-carrier schedule.

在一實施例中,該映射可以根據一映射規則,其中例如以升序或降序方式將以跨載波排程安排之服務小區的服務小區索引映射至該等排程小區特定載波指示欄位值。 In an embodiment, the mapping may be based on a mapping rule in which the serving cell index of the serving cell scheduled in the cross-carrier scheduling is mapped to the scheduled cell specific carrier indication field values, for example, in ascending or descending order.
在項目506中,該終端裝置從該網路節點接收該控制資訊。 In item 506, the terminal device receives the control information from the network node.
在關於第5圖之另一實施例中,在項目501中,一網路節點針對一終端裝置決定載波聚合之配置且至少一小區配置成以跨載波排程來安排,以便縱使用於載波聚合之配置小區的數目可以大於8個小區,以跨載波排程由單一排程小區所安排之小區數目為8個或以下小區。在項目502中,根據該決定,該網路節點對載波聚合傳送一配置信息至該終端裝置。該配置信息包括至少一資訊元素,其指示以該跨載波排程由單一排程小區安排至少一小區,以便以該跨載波排程安排之小區的數目為8個或以下小區。在項目503中,該終端裝置對載波聚合從該網路節點接收該配置信息。在項目504中,該網路節點實施該服務小區至一排程小區特定載波指示值之映射。 In another embodiment with respect to FIG. 5, in item 501, a network node determines a carrier aggregation configuration for a terminal device and at least one cell is configured to be arranged in a cross-carrier schedule for use in carrier aggregation. The number of configured cells may be greater than 8 cells, and the number of cells arranged by a single scheduled cell in a cross-carrier schedule is 8 or less. In item 502, in accordance with the decision, the network node transmits a configuration message to the carrier device for carrier aggregation. The configuration information includes at least one information element indicating that at least one cell is scheduled by the single scheduled cell in the cross-carrier scheduling such that the number of cells scheduled by the cross-carrier scheduling is 8 or less. In item 503, the terminal device receives the configuration information from the network node for carrier aggregation. In item 504, the network node implements mapping of the serving cell to a scheduled cell specific carrier indication value.
在項目505中,該網路節點經由一排程小區傳送關於跨載波排定服務小區之下行鏈路控制資訊至該終端裝置。該下行鏈路控制資訊包括一載波指示欄位。該載波指示欄位值係根據一服務小區至一排程小區特定載波指示欄位值的映射504。在項目506中,該終端裝置從該網路節點接收該下行鏈路控制資訊,其中該終端裝置實施從載波指示欄位至服務小區之反向排程小區特定映射,以便獲得一排程小區之控制資訊。 In item 505, the network node transmits, via a scheduled cell, downlink control information about the downlink control serving cell to the terminal device. The downlink control information includes a carrier indication field. The carrier indication field value is a mapping 504 that indicates a field value based on a particular cell to a scheduled cell. In item 506, the terminal device receives the downlink control information from the network node, wherein the terminal device implements a reverse-scheduled cell-specific mapping from a carrier indication field to a serving cell to obtain a scheduled cell Control information.
在一實施例中,在項目504之網路中服務小區與一排程小區特定載波指示欄位值間之映射及在項目506之UE中的反向映射係根據相同映射規則。此映射規則可以依據一預定映射規則。 In one embodiment, the mapping between the serving cell and a scheduled cell specific carrier indication field value in the network of item 504 and the reverse mapping in the UE of item 506 are based on the same mapping rules. This mapping rule can be based on a predetermined mapping rule.
在另一選擇中,該eNB本身可以決定服務小區與一排程小區特定載波指示欄位值間之映射及通知該預定UE關於該映射規則。該UE在此情況下可以根據RRC信號使用該排程小區特定CIF與一服務小區間之映射506。明確地發出RRC信號,亦即,該配置信息502亦可以指示CIF用於一既定SCell或者RRC信號(亦即,該配置信息502)配置SCell及指示哪一個小區為該排程小區及接著根據一預定映射規則使用該映射506。DCI攜帶CIF,其中根據該映射,UE知道正在安排哪一個SCell。 In another option, the eNB itself may determine a mapping between the serving cell and a scheduled carrier specific carrier indication field value and inform the predetermined UE about the mapping rule. In this case, the UE may use the mapping 506 between the scheduled cell-specific CIF and a serving cell according to the RRC signal. The RRC signal is explicitly sent, that is, the configuration information 502 may also indicate that the CIF is used for a predetermined SCell or RRC signal (ie, the configuration information 502) to configure the SCell and indicate which cell is the scheduled cell and then according to the This mapping 506 is used by predetermined mapping rules. The DCI carries a CIF, where according to the mapping, the UE knows which SCell is being scheduled.
為了服務小區索引、對應排程小區識別符及載波指示欄位間之映射,該終端裝置及該網路節點可以維持預定映射規則(例如,映射表或一些其它資料結 構)。在另一選擇中,可以例如藉由使用該RRC信號502,在該網路節點中決定501適當的映射規則資訊及將它從該網路節點提供至該終端裝置。 The terminal device and the network node may maintain predetermined mapping rules (eg, a mapping table or some other data node) for mapping between the serving cell index, the corresponding scheduled cell identifier, and the carrier indication field. Structure). In another option, appropriate mapping rule information can be determined 501 in the network node and provided from the network node to the terminal device, for example by using the RRC signal 502.
在一實施例中,根據單一排程小區之排定小區的數目可以限制在8個或以下小區內。在DCI中之CIF值的解讀及映射不需要增加3-位元CIF長度來支援8個以上服務小區。此限制不會影響跨載波排程操作,因為對於根據單一排程小區之大數目的排定小區,會有PDCCH/EPDCCH阻塞干擾(blocking)(亦即,需要從該單一排定小區之PDCCH/EPDCCH傳送很多DCI)。 In an embodiment, the number of scheduled cells according to a single scheduled cell may be limited to 8 or less cells. Interpretation and mapping of CIF values in DCI does not require an increase in 3-bit CIF length to support more than 8 serving cells. This limitation does not affect cross-carrier scheduling operations because there is PDCCH/EPDCCH blocking for a large number of scheduled cells according to a single scheduled cell (ie, PDCCH/from this single scheduled cell is required) EPDCCH transmits a lot of DCI).
在一實施例中,可以實施服務小區索引至CIF映射,以便CIF只以遞增順序指示該單一排定小區之配置小區的服務小區索引,其甚至在3位元CIF受限於0至7的數值下能提供小區大於7的服務小區索引。 In an embodiment, the serving cell index to CIF mapping may be implemented such that the CIF indicates the serving cell index of the configured cell of the single scheduled cell only in ascending order, even if the 3-bit CIF is limited to a value from 0 to 7. A serving cell index with a cell greater than 7 can be provided.
可以實施該服務小區索引CIF映射如下。例如,假設UE配置有14個小區/載波之載波聚合及該配置定義用於該14個小區之每一者(跨載波)的兩個排程小區。對於這14個小區,在表1中顯示依據較高層配置之用於該等小區的每一者之排程小區。 The serving cell index CIF mapping can be implemented as follows. For example, assume that the UE is configured with carrier aggregation of 14 cells/carriers and the configuration defines two scheduled cells for each of the 14 cells (cross-carrier). For these 14 cells, the scheduled cells for each of the cells according to the higher layer configuration are shown in Table 1.
在此範例中,考量兩個排程小區,其具有SchedulingCellId#0及SchedulingCellId#1。當PCell之ServCellIndex每一次為0時,在此範例中之第一排程小 區為PCell,以及該第二排程小區為具有ServingCellIndex 1之SCell。在該14個小區(ServCellIndex-r13為[0,...,13])中,除了根據PCell之自排程外,還配置5個小區用於根據PCell之跨載波排程(小區#3、4、5、6、10),以及一第一排程SCell(具有ServingCellIndex 1)配置用以安排小區#1(亦即,自排程)及用於小區#2、7、8、9、11、12、13之跨載波排程。對於PCell,依據上述服務小區索引之遞增順序整理待安排小區之服務小區索引,以及針對表2所示之跨載波排程分配相關的CIF(亦即,定義映射)。 In this example, consider two scheduled cells with SchedulingCellId#0 and SchedulingCellId#1. When the PCell's ServCellIndex is 0 each time, the first schedule in this example is small. The area is PCell, and the second scheduled cell is an SCell with ServingCellIndex 1. In the 14 cells (ServCellIndex-r13 is [0, ..., 13]), in addition to self-scheduling according to PCell, 5 cells are configured for cross-carrier scheduling according to PCell (Cell #3, 4, 5, 6, 10), and a first scheduled SCell (with ServingCellIndex 1) configured to arrange cell #1 (ie, self-scheduled) and for cells #2, 7, 8, 9, 11 , 12, 13 cross-carrier scheduling. For the PCell, the serving cell index of the cell to be scheduled is sorted according to the increasing order of the serving cell index, and the related CIF (that is, the defined mapping) is allocated for the cross-carrier scheduling shown in Table 2.
因此,在PCell上之DCI中的CIF=2映射至ServCellIndex-r13=4,以及CIF=5指示ServCellIndex-r13=10。於是,對於該第二排程小區,實施像上述相同的映射(見表3)。 Therefore, CIF=2 in the DCI on the PCell maps to ServCellIndex-r13=4, and CIF=5 indicates ServCellIndex-r13=10. Thus, for the second scheduled cell, the same mapping as described above is implemented (see Table 3).
因此,對於由相同小區所安排之每一小區,藉由以遞增順序整理之小區的服務小區索引之位置來決定小區之CIF值。UE執行可以根據該配置維持這樣的映射表。 Thus, for each cell scheduled by the same cell, the CIF value of the cell is determined by the location of the serving cell index of the cell sorted in ascending order. The UE implementation can maintain such a mapping table according to the configuration.
在另一範例中,假設具有14個載波(ServCellIndexes 0...13),其中例如由PCell(ServCellIndex=0)以跨載波方式安排7個載波。讓我們假設由PCell以跨載波方式安排偶數小區,則需要CIF=0...7與服務小區索引=0、2、4、6、8、10、12間之映射。為了決定該映射,提供兩個選擇,其包括預定映射規則及明確RRC信號。根據一規則,CIF=0對映至ServCellIndex=0、CIF=1對映至ServCellIndex=2、......、CIF=6對映至ServCellIndex=12(以升序方式)。此相似於上述表2。關於明確RRC信號,任何映射係可能的,例如,該映射可以是:
可以如下將此落實到RRC規範。當添加SCell時,它被賦予一個sCellIndex值(等於ServCellIndex): This can be implemented to the RRC specification as follows. When SCell is added, it is given a sCellIndex value (equal to ServCellIndex):
在RadioResourceConfigDedicatedSCell內,具有包括一跨載波排程配置之PhysicalConfigDedicatedSCell: Within the RadioResourceConfigDedicatedSCell, there is a PhysicalConfigDedicatedSCell that includes a cross-carrier scheduling configuration:
(除此之外)上述還區別該排程小區(該排程小區之ServCellIndex)與要安排該配置SCell之情況。可以針對此SCell加入所要使用之CIF值(參見下面cifInSchedulingCell-r13...INTEGER(0..7))(例如,當以sCellIndex=6配置SCell時,設定可以是CIF=1): (Other than this) The above also distinguishes between the scheduled cell (the ServCellIndex of the scheduled cell) and the case where the configured SCell is to be scheduled. The CIF value to be used can be added to this SCell (see cifInSchedulingCell-r13...INTEGER(0..7) below) (for example, when SCell is configured with sCellIndex=6, the setting can be CIF=1):
在一實施例中,可由一排程小區安排高達8個成分載波,以及在不需增加下行鏈路控制資訊格式中之CIF大小來支援8個以上服務小區下,擴展該跨載波排程操作。 In an embodiment, up to 8 component carriers can be arranged by a scheduling cell, and the cross-carrier scheduling operation can be extended without supporting the CIF size in the downlink control information format to support more than 8 serving cells.
在另一實施例中,以遞減順序方式整理該等ServCellIndexes,及/或可以定義及實施任何其它適當ServCellIndex排序規則。該規則之定義能使該映射不需要額外的RRC信號。 In another embodiment, the ServCellIndexes are organized in a descending order, and/or any other suitable ServCellIndex ordering rules may be defined and implemented. The definition of this rule enables the mapping to require no additional RRC signals.
在另一實施例中,該映射可以是可配置的,亦即,例如,當添加由一既定小區所安排之SCell時,該RRC信號可以明確地指示CIF與ServCellIndex間之映射。如果該添加SCell之ServCellIndex係在現有SCells的ServCellIndexes間,則可以維持該等先前SCells之映射,亦即,所要安排之SCell的添加沒有改變其它CIFs之映射。上述可以例如藉由在CrossCarrierSchedulingConfig中加入像cifValueInSchedulingCell之參數在RRC中執行。在此情況下,關於表2及表3,該兩個排程小區之映射在此範例中由較高層信號來直接提供。 In another embodiment, the mapping may be configurable, that is, for example, when adding an SCell scheduled by a given cell, the RRC signal may explicitly indicate a mapping between CIF and ServCellIndex. If the ServCellIndex of the added SCell is between the ServCellIndexes of the existing SCells, the mapping of the previous SCells can be maintained, that is, the addition of the SCell to be scheduled does not change the mapping of other CIFs. The above may be performed in the RRC, for example, by adding a parameter like cifValueInSchedulingCell in the CrossCarrierSchedulingConfig. In this case, with respect to Tables 2 and 3, the mapping of the two scheduled cells is provided directly by the higher layer signals in this example.
該CIF值亦可能影響關於PDCCH及EPDCCH之使用者特定搜尋空間定義,其中該CIF值針對該等排定小區之每一者提供搜尋空間之偏移。此可以擴展成配合該映射表/程序如下。1)該CIF值可以用以取代在該搜尋空間定義中之ServingCellId;在此情況下,該搜尋空間在M*7的最大偏移下保持相當小巧的,但是可能稍微不同於定義該CIF值(當作CIF映射之另一種解決方法)之情況。在此情況下,n_CIF係該映射表之CIF值。2)在另一選擇中,可以在PDCCH/EPDCCH使用者特定搜尋空間定義中使用ServingCellId;在此情況下,像在擴展CIF至5個位元之情況,在M*31的最大偏移下確切地定義相同搜尋空間。在此情況下,n_CIF之定義為ServingCellId。在此,M意指在一既定搜尋空間中所要監控之候選PDCCH數目。 The CIF value may also affect user-specific search space definitions for PDCCH and EPDCCH, where the CIF value provides a search space offset for each of the scheduled cells. This can be extended to match the mapping table/program as follows. 1) The CIF value can be used to replace the ServingCellId in the search space definition; in this case, the search space remains fairly small at the maximum offset of M*7, but may be slightly different from defining the CIF value ( As a solution to CIF mapping). In this case, n_CIF is the CIF value of the mapping table. 2) In another option, the ServingCellId may be used in the PDCCH/EPDCCH user-specific search space definition; in this case, as in the case of extending CIF to 5 bits, the exact offset of M*31 is Define the same search space. In this case, n_CIF is defined as ServingCellId. Here, M means the number of candidate PDCCHs to be monitored in a given search space.
一實施例能增加跨載波排程能力。在不需增加CIF大小下,使高達32個成分載波之跨載波排程成為可能。對於32個成分載波,可以配置4個或以上排程小區,每一排程小區受限於安排8個或以下小區。因此,在不需加大在DCI格式中之CIF長度下,將該跨載波排程擴展至高達32個小區。DCI解碼效能不受負可影響,以及具有相同大小之DCIs的可能性較小。執行每一排程小區之CIF對ServingCellId映射,其中可以藉由一簡單規則(遞增、遞減順序等)或藉由較高層信號(例如,RRC信號)來提供映射。可以由該單一排程小區安排高達8個載波。 An embodiment can increase cross-carrier scheduling capabilities. Cross-carrier scheduling of up to 32 component carriers is possible without increasing the CIF size. For 32 component carriers, 4 or more scheduled cells can be configured, and each scheduled cell is limited to arranging 8 or less cells. Therefore, the cross-carrier scheduling is extended to up to 32 cells without increasing the CIF length in the DCI format. DCI decoding performance is not affected by negative, and there is less likelihood of DCIs of the same size. The CIF pair ServingCellId mapping for each scheduled cell is performed, where the mapping can be provided by a simple rule (incremental, decremental order, etc.) or by a higher layer signal (eg, an RRC signal). Up to 8 carriers can be arranged by the single scheduled cell.
在一實施例中,可以在該下行鏈路控制資訊中使用一根據該映射規則所獲得之排程小區特定載波指示欄位值,以便識別對應排定服務小區。在一實施例中,可以使用一根據該映射規則所獲得之排程小區特定載波指示欄位值,以便識別對應跨載波排定服務小區之搜尋空間。 In an embodiment, a scheduled cell-specific carrier indication field value obtained according to the mapping rule may be used in the downlink control information to identify a corresponding scheduled serving cell. In an embodiment, a scheduled cell-specific carrier indication field value obtained according to the mapping rule may be used to identify a search space corresponding to the cross-carrier scheduled serving cell.
現在讓我們根據第6及7圖來更詳細描述該跨載波排程之實施例。參考第6圖,在項目601中,一網路節點針對一終端裝置決定以跨載波排程安排之至少一小區的載波聚合之配置。該配置包括用於載波聚合之8個以上的服務小區。然而,本發明之實施例並非侷限於此用以做為範例之數目。在一實施例中,該網路節點可以決定以跨載波排程安排之該配置服務小區的服務小區索引與一排程小區特定載波指示欄位值間之映射。 Let us now describe this cross-carrier scheduling embodiment in more detail in accordance with Figures 6 and 7.

The control information includes a carrier indication field, wherein the carrier indication field value is based on a mapping between a serving cell index and a scheduled cell specific carrier indication field value.
在項目703中,該終端裝置可利用服務小區索引、對應排程小區識別符及載波指示欄位間之映射。該終端裝置可以維持預定映射規則(例如,映射表),以 便在服務小區索引、對應排程小區識別符及載波指示欄位間映射。在另一選擇中,可以在該網路節點中決定及在該終端裝置中例如以該配置信息從該網路節點接收701適當映射規則資訊。 In item 703, the terminal device may utilize a mapping between the serving cell index, the corresponding scheduled cell identifier, and the carrier indication field. The terminal device can maintain a predetermined mapping rule (eg, a mapping table) to The mapping between the serving cell index, the corresponding scheduled cell identifier and the carrier indication field is performed. In another option, the appropriate mapping rule information can be determined and received in the network device from the network node, for example, with the configuration information.
