摘要： Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.

摘要： Methods and arrangements in a base station and a User Equipment are provided. The methods and arrangements relates to the scenario when the UE is handed over from a source base station to a target base station in a handover scenario, and wherein the target base station may not support functionalities which the source base station and the UE support. The method in the UE comprises receiving (501) a configuration message from the target base station via the source base station, configuring (502) the UE based on the received configuration message from the target base station by searching (503) for a second field in an information element of the received configuration message. The presence/non-presence or a value of the second field is indicative of how to manage a configured first functionality associated with an optional first field, wherein the configured first functionality may not be supported by the target base station.

摘要： A method in a first network node for handover preparation of a user equipment of a first category in a wireless communications network. The handover preparation is performed between a first cell served by the first network node and a second cell served by a second network node comprised in the wireless communications network. The first network node sends (301) to the second network node a message comprising information indicating a request for preparation of a handover of the user equipment. The request is specific for user equipment of the first category.The first network node receives (302) from the second network node a message indicating failure to prepare the handover.The first network node interprets (303) the message indicating failure to prepare the handover as an indication that the second network node does not support any user equipment of the first category.

摘要： A network node (600), a wireless device (602) and methods for controlling a radio communication using carrier aggregation. The wireless device (602) sends (6:1) UE capabilities to the network node (600), indicating a maximum capability limit per component carrier and a total maximum capability limit across all component carriers to be used in the radio communication. The network node (600) further selects (6:2) a number of component carriers to be used by the wireless device, and configures (6:3) radio features on the selected component carriers based on the received UE capabilities. The network node (600) then signals (6:4) the selected number of component carriers and the configured radio features to the wireless device (602) for use in the radio communication (6:5). Thereby, the network node (600) can utilize the full capabilities of the wireless device (602) when configuring the radio features while still respecting both the maximum capability limit per carrier and the total maximum capability limit.

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： Network Node, NN, (500, 202, 302) and User Equipment, UE, (700, 201, 301) and methods therein, for changing a state of transmission time interval, TTI, Bundling. The method in a NN involves determining whether a transmission time interval, TTI, Bundling setting of the UE should be changed from one state to the other of a state ON and a state OFF. When it is decided (402) that the TTI Bundling setting of the UE should be changed, a message is transmitted to the UE, indicating the decided change of TTI Bundling setting. Further, as a consequence of the decision to change the TTI Bundling setting, and in association with the transmission of the message, mobility control information is transmitted to the UE, indicating the cell A as target cell, in order to cause the UE to perform an intra-cell hand over procedure.
