摘要： Methods, nodes, computer programs, computer program products and a mobile network for adapting a mobile network are described. In such a method for adapting a mobile network (800), a terminal (802) is connected to a first access node (804) of the mobile network (800) via a first connection and to a second access node (808) via a second connection. The first access node (804) controls a data transmission for the terminal (802) and the second access node (808) assists in the data transmission for the terminal (802). The method comprises determining (7) whether a quality of at least one of the first connection and the second connection is degraded, acquiring (7) quality degradation information about the degradation of the quality of at least one of the first connection and the second connection based on the step of determining, and adapting (896, 8, 898, 899, 10, 11) the mobile network (800) based on the step of acquiring. Thereby a network adaption can be enabled in an easy, efficient and fast way in a case in which at least one of the first connection and second connection may have been degraded or failed.

摘要： Cooperating nodes, and methods therein, for mobility procedures in a wireless communication system supporting UE groups. One of the cooperating nodes is a base station being associated with a UE group comprising UEs having correlated mobility related parameters. The method in the base station comprises receiving, from a first UE in the UE group, a mobility related parameter associated with the first UE. The method further comprises determining whether to initiate a mobility related procedure for a second UE in the UE group based on the received mobility related parameter; and further comprises initiating the mobility related procedure for the second UE when it is determined that the mobility related procedure is to be performed. Thereby, prediction and decisions related to mobility events, e.g. handover events, for the second UE or for the whole group may be performed e.g. before or without receiving any mobility information related to the second UE, thereby enabling early prediction and better preparation, which can lead to more robust mobility procedures.

摘要： The present disclosure relates to methods and arrangements for re-establishing packet data transfer between a radio base station and a wireless device following radio link failure, the radio base station having pre-configured wireless device information. The RBS receives a request for re-establishment of the radio link from the wireless device. One or more DRBs are selected for re-establishment based on the pre-configured wireless device information. The RBS transmits a radio link re-establishment response to the wireless device comprising information about the selected one or more DRBs. The selected one or more DRBs are re-established upon receipt of a re-establishment confirmation from the wireless device, whereupon packet data transfer is resumed.

摘要： A method for limiting Channel Quality Indicator (CQI) reporting from a User Equipment to a network node is provided where a User Equipment can transmit CQI reports to a network node, such as e.g. a base station, when the User Equipment is operating in low transmission and/or low reception activity mode. A limited CQI reporting is obtained by triggering the reporting according to one or more predefined rules, which to at least some extent depend on CQI specific information provided to the User Equipment from the network node. A User Equipment and a network node adapted to operate in accordance with the suggested method are also provided.

摘要： UTRAN MAC-d multiplexing of data from multiple logical channels to a single MAC-d flow is supported while reducing overhead and achieving octet alignment in MAC-d PDU length. In one embodiment, the C/T field of a multiplexed MAC-d PDU is eliminated, and the logical channels multiplexed into the MAC-d flow are mapped to a MAC-hs PQ in at least the NodeB (and preferably in the UE as well). In other embodiments, the C/T field is retained, and an octet-aligned length indicator is transmitted from the RNC to the UE. In one embodiment, the length indicator is octet-aligned by padding the MAC-d PDUs. In another embodiment, transmitters and receivers in the path from RNC to UE are configured with an offset to add to the length indicator to achieve octet alignment. The padding or offset is (8-n) bits, where n=the number of bits in C/T field.

摘要： Embodiments herein relate to a method performed in a wireless terminal (10) for managing or handling uplink, UL, data transmissions in a radio communications network (1), wherein the wireless terminal (10) is served by a first radio base station (12) and a second radio base station (13) providing dual connectivity to the wireless terminal (10) in the radio communications network (1). The wireless terminal (10) transmits a buffer status report, BSR, to the first and/or second radio base station when a trigger is being fulfilled as configured at the wireless terminal (10). Furthermore, the wireless terminal (10) handles multiplexing of an uplink data transmission towards the first and second radio base stations according to a static configuration defining how to multiplex Media Access Control Service Data Units, MAC SDUs, from one or different logical channels onto transport blocks to be delivered to a physical layer on transport channels of a given radio base station out of the first radio base station and the second radio base station; and/or according to a second configuration where if there is data available for multiple logical channels with equal priority towards one of the radio base stations, then data of a logical channel for which the buffer status report is configured towards a radio base station providing a grant, is prioritized
