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 subframes. The subframes 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： According to various embodiments, a method is provided at a relay node for enabling subframe allocation between a backhaul link and an access link of the relay node. The relay node is connected to a controlling entity via the backhaul link, and is connectable to at least one user equipment via the access link. The relay node receives a trigger or configuration information from the controlling entity from the controlling entity. Based on the received trigger or configuration information, the relay node sends information to the controlling entity, indicating a resource utilization of the access link and/or indicating a quality of the access link.

摘要： Teachings herein include a base station for propagating system information changes from the base station to the relay node. Upon transmitting system information changes to the relay node, the base station defers data transmission between the base station and the relay node until a set time period. In many embodiments, the base station is configured to actually apply the system information changes during this time period, while the relay node 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 and the relay node 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 and relay node.
摘要翻译： 这里的教导包括用于将系统信息改变从基站传播到中继节点的基站。 在向中继节点发送系统信息变化时，基站延迟基站与中继节点之间的数据传输，直到设定的时间段为止。 在许多实施例中，基站被配置为在该时间段期间实际应用系统信息变化，而中继节点在接收之前例如通过在接收之后立即应用它们来应用变化。 因此，基站延迟数据传输直到设定的时间段因此确保在基站和中继节点已应用待决更改之前不发生数据传输。 这又防止由于基站和中继节点使用不同的系统参数而发生无线电链路故障。

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： 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.

摘要： Teachings herein include a base station and a relay node for propagating system information changes from the base station to the relay node. Upon receiving changes from the base station, the relay node advantageously determines whether to apply the changes immediately or to defer application until a set time period. The relay node then applies the changes at a time in accordance with that determination. In some embodiments, the relay node 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 may make the determination based on preconfigured rules, or on control indicators received from the base station. Correspondingly, the base station may generate the control indicators to explicitly direct the relay node to employ immediate application or deferred application.
