在LTE(Long Term Evolution，長期演進)的版本11(Release 11)中，協作多點傳輸(CoMP，Coordinated Multiple Points Transmission/Reception)被廣泛研究，其假設空閒回程連接以及中央化調度。在LTE的版本12中，其將被進一步增強，以具有更實際的網路設想和非空閒回程連接。典型的非空閒回程連接通常具有大約15-60ms的延遲，這將為協調調度帶來更大的設計挑戰。 In Release 11 of LTE (Long Term Evolution), Coordinated Multiple Points Transmission (CoMP) is widely studied, which assumes idle backhaul connections and centralized scheduling.

A typical non-idle backhaul connection typically has a delay of approximately 15-60 ms, which will present a greater design challenge for coordinated scheduling.
一個可行的解決方案是將用戶設備(UE，User Equipment)的通道狀態資訊發送至資源調度器，以使得資源調度器能夠根據其所接收的通道狀態資訊為每個細胞分配資源。然而，當前的X2介面並不支持上述資訊的交換。 A feasible solution is to send channel state information of the user equipment (UE, User Equipment) to the resource scheduler, so that the resource scheduler can allocate resources for each cell according to the channel state information it receives. However, the current X2 interface does not support the exchange of the above information.

下面結合圖式對本發明作進一步詳細描述。 The invention is further described in detail below with reference to the drawings.
本發明提供了一種基地台(eNB，evolved Node B)與中央節點(CN，Central Node)配合實現集中式細胞間資源協調的方案。圖1示例性示出本發明的一個系統示意圖。其中，eNB1和eNB2均與CN相連接，UE1由eNB1提供服務，UE2由eNB2提供服務。 The present invention provides a scheme in which a base station (eNB, evolved Node B) cooperates with a central node (CN, Central Node) to implement centralized inter-cell resource coordination. Fig. 1 exemplarily shows a system schematic of the present invention. eNB1 and eNB2 are both connected to the CN, UE1 is served by eNB1, and UE2 is served by eNB2.
配合參閱圖2，在時刻0，UE1向eNB1發送通道測量資訊，諸如CSI CSI/RSRP/RSRQ/ACK/NACK；UE2也向eNB2發送通道測量資訊，諸如CSI CSI/RSRP/RSRQ/ACK/NACK；eNB1和eNB2根據各自從UE接收到的通道 測量資訊，分別向CN發送通道狀態相關資訊，以供CN用於資源分配。 Referring to FIG. 2, at time 0, UE1 sends channel measurement information, such as CSI CSI/RSRP/RSRQ/ACK/NACK, to eNB1; UE2 also sends channel measurement information, such as CSI CSI/RSRP/RSRQ/ACK/NACK, to eNB2; eNB1 and eNB2 according to respective channels received from the UE The measurement information is sent to the CN to send channel status related information for the CN to allocate resources.

圖3示出根據本發明的一個實施例的方法流程圖，示出在基地台端配合實現集中式細胞間資源協調的過程。 3 shows a method flow diagram illustrating the process of implementing centralized inter-cell resource coordination at a base station end, in accordance with an embodiment of the present invention.
在步驟S301中，eNB1保留其對應細胞內的特定通道資源配置。 In step S301, eNB1 reserves a specific channel resource configuration within its corresponding cell.
具體地，配合參閱圖4a，在一個較佳示例中，為實現對多個細胞的資源配置，用於資源配置保留的X2發信被提出。 Specifically, with reference to FIG. 4a, in a preferred example, to implement resource configuration for multiple cells, an X2 signaling for resource configuration reservation is proposed.
CN向eNB1發送資源配置保留請求(resource configuration reserve request)，以請求eNB1保留特定資源配置。 The CN sends a resource configuration reserve request to the eNB1 to request the eNB1 to reserve the specific resource configuration.
如果eNB1返回攜帶成功指示資訊的資源配置保留確認消息(resource configuration reserve confirmation)，CN則隨後可以向eNB2發送資源配置保留請求，以向eNB2請求保留期望的資源配置。 If the eNB1 returns a resource configuration reserve confirmation message carrying the success indication information, the CN may then send a resource configuration reservation request to the eNB2 to request the eNB2 to reserve the desired resource configuration.
如果eNB1返回攜帶失敗指示資訊的資源配置保留確認消息或者在特定時間範圍內無應答，CN則會認為這樣 的資源配置保留請求失敗。 If eNB1 returns a resource configuration reservation acknowledgement message carrying the failure indication information or does not respond within a certain time range, the CN considers this The resource configuration reservation request failed.
在自CN接收資源配置保留請求之後，eNB2可以根據所接收的請求消息作出資源配置決定。 After receiving the resource configuration reservation request from the CN, the eNB 2 may make a resource configuration decision according to the received request message.
eNB2可以返回攜帶成功指示資訊或失敗指示資訊的資源配置保留確認消息給CN。 The eNB2 may return a resource configuration reservation confirmation message carrying the success indication information or the failure indication information to the CN.
在另一個較佳示例中，配合參閱圖4b，CN也可以同時分別向eNB1和eNB2發送資源配置保留請求，並從兩者分別接收相應的資源配置保留確認消息。 In another preferred example, referring to FIG. 4b, the CN may also send resource configuration reservation requests to eNB1 and eNB2, respectively, and receive corresponding resource configuration reservation acknowledgement messages from the two.
可替代地，eNB也可發起資源配置保留請求，並在CN返回資源配置保留確認消息後，保留其特定資源配置。 Alternatively, the eNB may also initiate a resource configuration reservation request and retain its specific resource configuration after the CN returns a resource configuration reservation acknowledgement message.
資源配置保留請求 Resource configuration reservation request
“資源配置保留請求”的X2發信請求目標細胞保留特定資源配置。其中，- “資源配置保留請求”應當/可以關聯目標細胞ID和/或有效時間範圍，例如，其指示具有有效配置的第一子框ID；- 所指定的資源配置在此可以是ZP CSI-RS(zero-power channel state information reference signal，零功率通道狀態資訊參考信號)，PDSCH(physical downlink shared channel，物理下行鏈路共享通道)，NZP CSI-RS(non-zero power channel state information reference signal，非零功率通道狀態資訊參考信號)，CSI-IM( CSI-interference measurement CSI干擾測量)，CSI過程(CSI-process)，時頻資源限制，PDSCH傳輸功率設置限制和/或特定PMI限制；- 對於現有配置，X2發信可以直接指示配置標識或/或細胞ID/虛擬細胞ID。 The X2 Send Request for the Resource Configuration Retention Request requests the target cell to reserve a specific resource configuration. Wherein, the "resource configuration reservation request" should/can be associated with the target cell ID and/or the valid time range, for example, it indicates the first sub-frame ID with a valid configuration; - the specified resource configuration may be ZP CSI - RS (zero-power channel state information reference signal), PDSCH (physical downlink shared channel), NZP CSI-RS (non-zero power channel state information reference signal, Non-zero power channel status information reference signal), CSI-IM ( CSI-interference measurement, CSI-process, time-frequency resource limitation, PDSCH transmission power setting restriction and/or specific PMI limitation; - For existing configurations, X2 signaling can directly indicate the configuration identifier and/or Cell ID / Virtual Cell ID.
資源配置保留確認消息 Resource configuration reservation confirmation message
如果“資源配置保留確認消息”攜帶成功指示資訊，這表示發送該消息的eNB承諾保留相應的資源配置直到有來自發送該消息的eNB、其他相鄰eNB或CN的新消息。 If the "resource configuration reservation acknowledgement message" carries the success indication information, this means that the eNB that sent the message promises to reserve the corresponding resource configuration until there is a new message from the eNB that sent the message, other neighboring eNBs, or the CN.
如果“資源配置保留確認消息”攜帶失敗指示資訊，這表示發送該消息的eNB不承諾保留相應的資源配置。 If the “resource configuration reservation acknowledgement message” carries the failure indication information, this means that the eNB that sent the message does not promise to reserve the corresponding resource configuration.
資源配置請求 Resource configuration request
圖4a中示出的“資源配置請求”的X2發信與“資源配置保留請求”相同，同樣具有或不具有資源保留功能。 The X2 signaling of the "Resource Configuration Request" shown in FIG. 4a is the same as the "Resource Configuration Reservation Request", with or without resource reservation.
接下來，配合參閱圖5，CN可以發送“資源配置保留釋放消息”給eNB1，以釋放相應的資源配置。 Next, referring to FIG. 5, the CN may send a “Resource Configuration Reservation Release Message” to the eNB1 to release the corresponding resource configuration.
在自CN接收到“資源配置保留釋放消息”之後，eNB1可以決定是否釋放相應資源配置。並且，釋放決定並不意味eNB1將立即替換這樣的資源配置，而是意味eNB1不再承諾保留資源配置。 After receiving the "Resource Configuration Reservation Release Message" from the CN, the eNB1 may decide whether to release the corresponding resource configuration. Moreover, the release decision does not mean that eNB1 will immediately replace such a resource configuration, but rather that eNB1 no longer promises to reserve the resource configuration.
由“資源配置保留釋放消息”所指示的資源配置可以與接收該消息的eNB或發起該消息的eNB相對應。也即， CN和eNB均可發起“資源配置保留釋放消息”。如果該消息指示發起eNB，則意味該發起eNB不再承諾保留所指定的資源配置。在此，所指定的資源配置可以是ZP CSI-RS(zero-power channel state information reference signal，零功率通道狀態資訊參考信號)，PDSCH(physical downlink shared channel，物理下行鏈路共享通道)，NZP CSI-RS(non-zero power channel state information reference signal，非零功率通道狀態資訊參考信號)，CSI-IM(CSI-interference measurement，CSI干擾測量)，CSI過程(CSI-process)，時頻資源限制，PDSCH傳輸功率設置限制和/或特定PMI限制。 The resource configuration indicated by the "Resource Configuration Reservation Release Message" may correspond to the eNB receiving the message or the eNB initiating the message. That is, Both the CN and the eNB may initiate a "resource configuration reservation release message". If the message indicates the originating eNB, it means that the initiating eNB no longer promises to reserve the specified resource configuration. The specified resource configuration may be a ZP CSI-RS (zero-power channel state information reference signal), a PDSCH (physical downlink shared channel), and an NZP CSI. -RS (non-zero power channel state information reference signal), CSI-IM (CSI-interference measurement), CSI process (CSI-process), time-frequency resource limitation, PDSCH transmission power setting limits and/or specific PMI limits.
返回參閱圖3，在步驟S302中，eNB1根據其細胞內各UE上報的通道測量資訊，向CN發送其細胞的通道狀態相關資訊，以供CN根據各細胞上報的通道狀態相關資訊來為相關細胞進行集中資源分配。 Referring back to FIG. 3, in step S302, the eNB1 sends the channel state related information of the cell to the CN according to the channel measurement information reported by each UE in the cell, so that the CN can be based on the channel state related information reported by each cell.

- 細胞內相關用戶設備的緩衝狀態資訊； - buffer status information of relevant user equipment in the cell;
由於X2延遲，CN不知道每個細胞所服務UE的實時緩衝狀態，因此，如果X2延遲較長，CN不需要為具有較小剩餘流量卸載(rest traffic offload)的UE分配資源，從而需要考慮通過X2介面的用於CSI資訊報告的UE選擇問題。eNB可以模糊報告相關UE的緩衝狀態，如重/中/輕，或增加/穩定/減少。 Due to the X2 delay, the CN does not know the real-time buffer status of the UE served by each cell.

不同的傳輸模式將導致不同的資源分配。因此，傳輸模式可以在eNB和CN之間進行交換。傳輸模式可以包括以下全部或部分資訊：在所指定細胞的相同時頻資源上最大調度用戶數量；單用戶調度或多用戶調度；TM1/2/../TM10；每個UE的等級限定，可以由RI指示替換。 Different transmission modes will result in different resource allocations. Therefore, the transmission mode can be exchanged between the eNB and the CN. The transmission mode can include all or part of the following information: The maximum number of users scheduled on the same time-frequency resource of the designated cell; Single user scheduling or multi-user scheduling; TM1/2/../TM10; The level of each UE is defined and can be replaced by an RI indication.
CN在接收到各細胞上報的通道狀態相關資訊後，為相關細胞做出資源分配決定。由CN發送至eNB的資源分配資訊可以包括具有有效時間範圍的功率分配、波束分配和調度分配，例如第一個有效子框的ID。 After receiving the channel state related information reported by each cell, the CN makes resource allocation decisions for the relevant cells. The resource allocation information transmitted by the CN to the eNB may include power allocation, beam allocation, and scheduling allocation with a valid time range, such as the ID of the first valid sub-frame.
其中：- 波束分配資訊包括碼本限制資訊、天線端口號及等級號，以及W1的指示符或W1與W2的混合波束(joint beam)的指示符；- 波束分配資訊包括CSI過程、CSI-RS和CSI-IM的指示資訊； - 多級別波束分配資訊包括多組波束分配資訊；- 功率設置資訊與波束和/或頻率單元和/或時間單元的組合相關聯，以指示在發起具有給定組合的傳輸點(TP，Transmission Point)的功率設置；- 調度分配資訊包括更強干擾源的指示資訊；- 用於資源調度調整的資源使用資訊和干擾級別。 Wherein: - The beam allocation information includes codebook restriction information, antenna port number and class number, and an indicator of W1 or an indicator of a hybrid beam of W1 and W2; - beam allocation information including CSI process, CSI-RS And CSI-IM instructions; - Multi-level beam allocation information includes multiple sets of beam allocation information; - Power setting information is associated with a combination of beams and/or frequency units and/or time units to indicate that a transmission point with a given combination is initiated (TP, Transmission Point Power setting; - scheduling allocation information includes indication information of stronger interference sources; - resource usage information and interference level used for resource scheduling adjustment.
隨後，在步驟S303中，eNB1根據CN返回的資源分配資訊，在所保留的特定通道資源上對其細胞內的各UE進行調度。在此，CN可以僅返回關於eNB1的細胞的資源分配資訊，也可以同時提供其他細胞的資源分配資訊，以供eNB1進行資源分配調整。 Then, in step S303, the eNB1 schedules each UE in the cell on the reserved specific channel resource according to the resource allocation information returned by the CN. Here, the CN may only return resource allocation information about the cells of the eNB1, or may simultaneously provide resource allocation information of other cells for the eNB1 to perform resource allocation adjustment.
圖6示出根據本發明的另一個實施例的裝置示意圖，示出在基地台端配合實現集中式細胞間資源協調的裝置。如圖6所示，裝置60裝置於eNB1中，包括資源保留裝置601、資訊報告裝置602和資源調度裝置603。 6 shows a schematic diagram of a device in accordance with another embodiment of the present invention showing a device for coordinating centralized inter-cell resource coordination at a base station end. As shown in FIG. 6, the device 60 is installed in the eNB1, and includes a resource reservation device 601, an information reporting device 602, and a resource scheduling device 603.
資源保留裝置601保留eNB1所對應細胞內的特定通道資源配置。 The resource reservation device 601 reserves a specific channel resource configuration within the cell corresponding to the eNB1.
具體地，配合參閱圖4a，在一個較佳示例中，為實現對多個細胞的資源配置，用於資源配置保留的X2發信被提出。 Specifically, with reference to FIG. 4a, in a preferred example, to implement resource configuration for multiple cells, an X2 signaling for resource configuration reservation is proposed.
CN向eNB1發送資源配置保留請求(resource configuration reserve request)，以請求eNB1保留特定資源配置。 The CN sends a resource configuration reserve request to the eNB1 to request the eNB1 to reserve the specific resource configuration.
如果eNB1的資源保留裝置601返回攜帶成功指示資 訊的資源配置保留確認消息(resource configuration reserve confirmation)，CN則隨後可以向eNB2發送資源配置保留請求，以向eNB2請求保留期望的資源配置。 If the resource reservation device 601 of the eNB1 returns the carrying success indication The resource configuration reserve confirmation message may be sent by the CN to the eNB2 to request the eNB2 to reserve the desired resource configuration.
如果eNB1的資源保留裝置601返回攜帶失敗指示資訊的資源配置保留確認消息或者在特定時間範圍內無應答，CN則會認為這樣的資源配置保留請求失敗。 If the resource reservation device 601 of the eNB1 returns a resource configuration reservation acknowledgement message carrying the failure indication information or does not respond within a certain time range, the CN may consider such a resource configuration reservation request to fail.
在自CN接收資源配置保留請求之後，eNB2可以根據所接收的請求消息作出資源配置決定。同樣地，eNB2也具有與上述裝置60相同的裝置(未示出)，以與CN配合實現本發明中的集中式資源分配。 After receiving the resource configuration reservation request from the CN, the eNB 2 may make a resource configuration decision according to the received request message. Similarly, eNB 2 also has the same means (not shown) as device 60 described above to cooperate with the CN to implement centralized resource allocation in the present invention.
eNB2的資源保留裝置可以返回攜帶成功指示資訊或失敗指示資訊的資源配置保留確認消息給CN。 The resource reservation apparatus of the eNB2 may return a resource configuration reservation confirmation message carrying the success indication information or the failure indication information to the CN.
在另一個較佳示例中，配合參閱圖4b，CN也可以同時分別向eNB1和eNB2發送資源配置保留請求，並從兩者的資源保留裝置分別接收相應的資源配置保留確認消息。 In another preferred example, referring to FIG. 4b, the CN may also send a resource configuration reservation request to eNB1 and eNB2 at the same time, and respectively receive corresponding resource configuration reservation confirmation messages from the resource reservation devices of the two.
可替代地，eNB的資源保留裝置也可發起資源配置保留請求，並在CN返回資源配置保留確認消息後，保留其特定資源配置。 Alternatively, the resource reservation device of the eNB may also initiate a resource configuration reservation request and reserve its specific resource configuration after the CN returns the resource configuration reservation acknowledgement message.
資源配置保留請求 Resource configuration reservation request
“資源配置保留請求”的X2發信請求目標細胞保留特定資源配置。其中，- “資源配置保留請求”應當/可以關聯目標細胞ID和/ 或有效時間範圍，例如，其指示具有有效配置的第一子框ID；- 所指定的資源配置在此可以是ZP CSI-RS(zero-power channel state information reference signal，零功率通道狀態資訊參考信號)，PDSCH(physical downlink shared channel，物理下行鏈路共享通道)，NZP CSI-RS(non-zero power channel state information reference signal，非零功率通道狀態資訊參考信號)，CSI-IM(CSI-interference measurement CSI干擾測量)，CSI過程(CSI-process)，時頻資源限制，PDSCH傳輸功率設置限制和/或特定PMI限制；- 對於現有配置，X2發信可以直接指示配置標識或/或細胞ID/虛擬細胞ID。 The X2 Send Request for the Resource Configuration Retention Request requests the target cell to reserve a specific resource configuration. Where - "Resource configuration reservation request" should / can be associated with the target cell ID and / Or a valid time range, for example, indicating a first sub-frame ID having a valid configuration; - the specified resource configuration may be a Z-CSI-RS (zero-power channel state information reference signal) ), PDSCH (physical downlink shared channel), NZP CSI-RS (non-zero power channel state information reference signal), CSI-IM (CSI-interference measurement) CSI interference measurement), CSI-process, time-frequency resource limitation, PDSCH transmission power setting limit and/or specific PMI limitation; - For existing configurations, X2 signaling can directly indicate configuration identification or/or cell ID/virtual Cell ID.
資源配置保留確認消息 Resource configuration reservation confirmation message
如果“資源配置保留確認消息”攜帶成功指示資訊，這表示發送該消息的eNB承諾保留相應的資源配置直到有來自發送該消息的eNB、其他相鄰eNB或CN的新消息。 If the "resource configuration reservation acknowledgement message" carries the success indication information, this means that the eNB that sent the message promises to reserve the corresponding resource configuration until there is a new message from the eNB that sent the message, other neighboring eNBs, or the CN.
如果“資源配置保留確認消息”攜帶失敗指示資訊，這表示發送該消息的eNB不承諾保留相應的資源配置。 If the “resource configuration reservation acknowledgement message” carries the failure indication information, this means that the eNB that sent the message does not promise to reserve the corresponding resource configuration.
資源配置請求 Resource configuration request
圖4a中示出的“資源配置請求”的X2發信與“資源配置保留請求”相同，同樣具有或不具有資源保留功能。 The X2 signaling of the "Resource Configuration Request" shown in FIG. 4a is the same as the "Resource Configuration Reservation Request", with or without resource reservation.
接下來，配合參閱圖5，CN可以發送“資源配置保留釋放消息”給eNB1，以釋放相應的資源配置。 Next, referring to FIG. 5, the CN may send a “Resource Configuration Reservation Release Message” to the eNB1 to release the corresponding resource configuration.
在自CN接收到“資源配置保留釋放消息”之後，eNB1的資源保留裝置601可以決定是否釋放相應資源配置。並且，釋放決定並不意味資源保留裝置601將立即替換這樣的資源配置，而是意味資源保留裝置601不再承諾保留資源配置。 After receiving the "resource configuration reservation release message" from the CN, the resource reservation device 601 of the eNB1 may decide whether to release the corresponding resource configuration. Moreover, the release decision does not mean that the resource reservation device 601 will immediately replace such a resource configuration, but rather that the resource reservation device 601 no longer promises to reserve the resource configuration.
由“資源配置保留釋放消息”所指示的資源配置可以與接收該消息的eNB或發起該消息的eNB相對應。也即，CN和eNB均可發起“資源配置保留釋放消息”。如果該消息指示發起eNB，則意味該發起eNB不再承諾保留所指定的資源配置。在此，所指定的資源配置可以是ZP CSI-RS(zero-power channel state information reference signal，零功率通道狀態資訊參考信號)，PDSCH(physical downlink shared channel，物理下行鏈路共享通道)，NZP CSI-RS(non-zero power channel state information reference signal，非零功率通道狀態資訊參考信號)，CSI-IM(CSI-interference measurement，CSI干擾測量)，CSI過程(CSI-process)，時頻資源限制，PDSCH傳輸功率設置限制和/或特定PMI限制。 The resource configuration indicated by the "Resource Configuration Reservation Release Message" may correspond to the eNB receiving the message or the eNB initiating the message. That is, both the CN and the eNB may initiate a "resource configuration reservation release message." If the message indicates the originating eNB, it means that the initiating eNB no longer promises to reserve the specified resource configuration. The specified resource configuration may be a ZP CSI-RS (zero-power channel state information reference signal), a PDSCH (physical downlink shared channel), and an NZP CSI. -RS (non-zero power channel state information reference signal), CSI-IM (CSI-interference measurement), CSI process (CSI-process), time-frequency resource limitation, PDSCH transmission power setting limits and/or specific PMI limits.

- 細胞內相關用戶設備的緩衝狀態資訊； - buffer status information of relevant user equipment in the cell;
由於X2延遲，CN不知道每個細胞所服務UE的實時緩衝狀態，因此，如果X2延遲較長，CN不需要為具有 較小剩餘流量卸載(rest traffic offload)的UE分配資源，從而需要考慮通過X2介面的用於CSI資訊報告的UE選擇問題。資訊報告裝置602可以模糊報告相關UE的緩衝狀態，如重/中/輕，或增加/穩定/減少。 Due to the X2 delay, the CN does not know the real-time buffer status of the UE served by each cell. Therefore, if the X2 delay is long, the CN does not need to have The UE with smaller residual traffic offload allocates resources, so it is necessary to consider the UE selection problem for CSI information reporting through the X2 interface.
