    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: 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

    摘要: According to the invention data in a number of logical downlink intended for one or more mobile terminals are received in a first mapping unit, where at least a first High Speed Radio Network Temporary identity is allocated to these logical downlink channels addressing a group of mobile terminals for allowing transmission of channel data for reception by mobile terminals. A mobile terminal then reads, from a Broadcast Control Channel, necessary information including a High Speed Radio Network Temporary identity allocated to at least one logical downlink channel, where at least said first identity exists among possible identities. It then listens to a high speed shared control channel for the read identity. In case it detects the identity, the terminal follows a scheduling command, receives data on a high-speed downlink shared channel and processes said data.

    摘要: A device receives information regarding allocation of an enhanced dedicated channel radio network temporary identifier (E-RNTI) to user equipment in a cell forward access channel (Cell_FACH) state, and receives information regarding a state change associated with the user equipment. The device determines that the E-RNTI can be released based on the state change, and provides, to another device, a request to release the E-RNTI in response to the state change and so that the E-RNTI can be used by other user equipment.
