摘要： In accordance with one embodiment of the present disclosure, a method of operating a relay node includes receiving information, at the relay node, information identifying a plurality of subfranies. The subfranies represent time periods during which a base station may grant the relay node permission to transmit to the base station on a first frequency. The method also involves selecting one of the identified subframes to be used for a transmission between the relay node and a wireless terminal on the first frequency and transmits to the wireless terminal a scheduling grant granting the wireless terminal permission to transmit information on the first frequency during the selected subframe.

摘要： A coordinating node avoids or reduces interference between relay nodes by coordinating subframe allocation forthe interfering relay nodes. The coordinating node identifies the interfering relay nodes that require the same subframe allocation and provides the necessary signaling so that the involved nodes get information concerning the subframe allocations. The system may be implemented using a centralized node (e.g., OAM) or distributed coordinating nodes.

摘要： Teachings herein include a base station (20) and a relay node (30) for propagating system information changes from the base station (20) to the relay node (30). Upon receiving changes from the base station (20), the relay node (30) advantageously determines whether to apply the changes immediately or to defer application until a set time period. The relay node (30) then applies the changes at a time in accordance with that determination. In some embodiments, the relay node (30) employs deferred application for fundamental changes (those changes that would fatally disrupt ongoing communications if applied before the set time period), but employs immediate application for non-fundamental changes in order to minimize relay node complexity. Regardless, the relay node (30) may make the determination based on preconfigured rules, or on control indicators received from the base station (20). Correspondingly, the base station (20) may generate the control indicators to explicitly direct the relay node (30) to employ immediate application or deferred application.
摘要翻译：这里的教导包括用于将系统信息变化从基站（20）传播到中继节点（30）的基站（20）和中继节点（30）。在接收到来自基站（20）的改变时，中继节点（30）有利地确定是立即应用改变还是推迟应用直到设定的时间段。中继节点（30）然后根据该确定一次应用改变。在一些实施例中，中继节点（30）使用延迟应用来进行基本改变（如果在设定的时间段之前应用，将致使中断正在进行的通信的那些改变），而是立即应用于非基本改变以便最小化中继节点复杂度。无论如何，中继节点（30）可以基于预先配置的规则或从基站（20）接收的控制指示符进行确定。相应地，基站（20）可以生成控制指示符以明确指示中继节点（30）采用立即应用或延迟应用。

摘要： Some embodiments provide a mobile relay node, RN, (16) with complete and valid neighbor cell information. The RN (16) requests this information from a donor base station (12) upon detecting a defined condition characteristically indicating that movement of the RN (16) has rendered previously obtained neighbor cell information incomplete or invalid. The RN (16) may generate the request to identify cells (18) currently neighboring the mobile cell (20). The donor base station (12) may then provide the RN (16) information that more specifically pertains to the mobile cell's neighbors, rather than generally pertaining to the donor cell's neighbors. Other embodiments compensate for the RN's incomplete or invalid neighbor cell information. These embodiments permit the RN (16) to identify a target cell (18) with a non-unique cell identifier in a handover message sent to the donor base station (12). The donor base station (12) resolves this non-unique identifier and replaces it with the corresponding unique identifier for sending the message towards the target cell (18).
摘要翻译：一些实施例提供具有完整且有效的相邻小区信息的移动中继节点RN（16）。 RN（16）在检测到特定地指示RN（16）的移动已经使先前获得的相邻小区信息不完整或无效的定义条件时，从施主基站（12）请求该信息。 RN（16）可以生成用于识别当前与移动小区（20）相邻的小区（18）的请求。捐助者基站（12）然后可以提供更具体地涉及移动小区的邻居的RN（16）信息，而不是通常属于供体小区的邻居。其他实施例补偿RN的不完整或无效的相邻小区信息。这些实施例允许RN（16）在发送到施主基站（12）的切换消息中使用非唯一小区标识符来识别目标小区（18）。施主基站（12）解析该非唯一标识符并用相应的唯一标识符替换它，以向目标小区（18）发送消息。

摘要： Embodiments herein relate to a method in a donor radio base station (12) for configuring information associated to radio bearers in a radio communications network. The donor radio base station (12) controls a relay node (10), and which relay node (10) serves a cell (11) and controls a number of first radio bearers (R1) over a first radio interface between the relay node (10) and at least one user equipment (17) served in the cell (11). The donor radio base station (12) further controls a number of second radio bearers (R2) over a second radio interface between the donor radio base station (12) and the relay node (10), and which donor radio base station (12) and relay node (10) are comprised in the radio communications network. The donor radio base station (12) receives characteristic information indicating a characteristic of the relay node (10). Additionally, the donor radio base station (12) configures bearer information associated with at least one of the first radio bearers (R1) and/or the second radio bearers (R2) based on the indicated characteristic in the received characteristic information. The configured bearer information is to be used in the radio communications network during operation.

摘要： Teachings herein include a base station (20) for propagating system information changes from the base station (20) to the relay node (30). Upon transmitting system information changes to the relay node (30), the base station (20) defers data transmission between the base station (20) and the relay node (30) until a set time period. In many embodiments, the base station (20) is configured to actually apply the system information changes during this time period, while the relay node (30) applies the changes before then, e.g., by applying them immediately upon reception. The base station's deferral of data transmission until the set time period thus ensures that data transmission does not occur until both the base station (20) and the relay node (30) have applied the pending changes. This in turn prevents radio link failure from occurring due to use of different system parameters by the base station (20) and relay node (30).
摘要翻译：这里的教导包括用于将系统信息改变从基站（20）传播到中继节点（30）的基站（20）。在向中继节点（30）发送系统信息变化时，基站（20）将基站（20）和中继节点（30）之间的数据传输延迟到设定的时间段。在许多实施例中，基站（20）被配置为在该时间段期间实际应用系统信息改变，而中继节点（30）例如通过在接收之后立即应用它们之前应用改变。基站延迟数据传输直到设定的时间段因此确保在基站（20）和中继节点（30）已经应用待决更改之前不发生数据传输。这进而防止由于基站（20）和中继节点（30）使用不同的系统参数而发生无线电链路故障。

摘要： A donor base station (12) serves a mobile cell (20) provided by a mobile relay node (16) and advantageously limits the cells that it notifies about its serving of the mobile cell (20) to those cells that currently neighbor both the donor cell and the mobile cell (20). To this end, the donor base station (12) determines, based on identifying information that identifies cells currently neighboring the mobile cell (20), a subset of cells that neighbor both the mobile cell (20) and the donor cell. The base station (12) then sends an update message to the subset indicating that it is serving the mobile cell (20).In some embodiments, the donor base station (12) generates the message to indicate that the particular cell it is serving is a mobile cell (20). The cells in the subset then control handover to or from that particular cell based on one or more defined handover triggering thresholds specific to mobile cells.
