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： Example embodiments presented herein are directed towards a wireless terminal and base station, and corresponding methods therein, for providing a handover for a subset of bearers associated with the wireless terminal. The subset of bearers is less than a total number of bearers associated with the wireless terminal. Thus, upon the completion of the handover procedure, at least one bearer will stay connected with a source base station.

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： Apparatus and methods are disclosed for mitigating interference to radio base stations. A first base station provides a served cell that at least partially overlaps a served cell of a second base station. The first and second base stations are part of a telecommunications system. The method includes identifying at least one carrier that is preferable for the second base station to utilize for communications with at least one UE to avoid interference. The method further includes communicating an instruction message from the first base station to the second base station that instructs the second base station to use the at least one carrier for communications.

摘要： The technology in this application identifies a relay cell serviced by a relay radio node in a radio access network (RAN) of a cellular communications system in which there is a radio connection between the relay radio node and a donor radio base station. The donor radio base station is identified by a RAN donor radio base station cell identifier. A RAN relay cell identifier is determined that uniquely identifies the relay cell within the RAN, the RAN relay cell identifier including a relay cell identifier and a donor base station identifier. The RAN relay cell identifier is then provided or used as needed so that the relay radio node can transmit the RAN relay cell identifier to uniquely identify the relay cell to one or more radio terminals in the RAN.

摘要： Underlay network node and macro base station and methods therein for enabling avoidance of interference in a cell extension area associated with an uplink/downlink imbalance. The underlay network node is assumed to be associated with a cell area A, and a cell extension area B, where the cell extension area B has an uplink/downlink imbalance in relation to a neighboring base station and the network node. The method in the underlay network node involves serving a UE in both uplink and downlink when the UE is located in cell area A. The method further involves serving a UE only in the uplink when the UE is located in cell extension area B, thus enabling avoidance of interference related to communication of a UE located in said cell extension area B.

摘要： A relay node (110) for a radio access network (100), arranged to be a relay node between one or more User Equipments (105) in a cell (125) of the radio access network and a base station (115) serving the cell. The relay node (110) is arranged to identify itself as a relay node in the cell (125) in the radio access network (100), and is also arranged to receive a non-support indication indicating that the base station serving the cell (125) is unable to support a relay node. The relay node (110) is arranged to, upon receiving said non-support indication, attempt to establish itself as a relay node in another cell.
