Abstract:
There is provided a method of operating a network node in a communication network, the communication network comprising a mobile device, a first base station and a second base station, the first base station having a lower transmission power than the second base station and being located within the coverage area of the second base station, the mobile device being located within an imbalanced region between the first base station and the second base station and being served by the first base station, the method in the network node comprising configuring the mobile device, the first base station and the second base station such that the mobile device transmits uplink data to the first base station, and the mobile device receives downlink data only from the second base station. Corresponding methods are provided for operating a mobile device and a second base station. A network node, mobile device and second base station are also provided that are configured to perform the respective operating methods.
Abstract:
In a method and a system Radio Link Control (RLC) Status Reports in a cellular radio system employing Acknowledge Mode (AM) RLC are not delivered in sequence, thereby obtaining an increased peak throughput. Thus, even when an in-sequence delivery exists, for example if the system uses HARQ transmission, it is not used for data related to the RLC status report.
Abstract:
There is provided a method of operating a node in a mobile communication network, the network comprising a mobile device, a first base station and a second base station, the first base station having a lower transmission power than the second base station and being within the coverage area of the second base station, the method in the node comprising determining (101; 111) whether the mobile device is in an imbalanced region or a part of an imbalanced region between the first base station and the second base station; and determining (103; 113-121) whether to switch the mobile device between a first connection state and a second connection state based on whether the mobile device is located in the imbalanced region or the part of the imbalanced region.
Abstract:
There is provided a method of operating a mobile device in a heterogeneous communications network, the heterogeneous communications network comprising first and second base stations, the first base station having a lower transmission power than the second base station and being within the coverage area of the second base station, the method comprising obtaining measurements of the quality of signals transmitted between the first base station and the mobile device and/or the second base station and the mobile device; and analyzing the measurements of the quality to determine whether the mobile device is located in an imbalanced region or part of an imbalanced region between the first and second base stations.
Abstract:
A radio network controller, RNC, 614, and a method therein, for enhancing reception quality of transmissions on an uplink control channel from a user equipment, UE, 613 to a serving base station, BS, 610. The RNC, the UE and the serving BS are comprised in a communication system 600. The method comprises, when conditions for boosting the uplink control channel are fulfilled, determining a boosting factor based on a ratio of path gains of a channel from the UE to the serving BS and of a channel from the UE to a non-serving BS 611, respectively, which non-serving BS is comprised in the communications system. The method further comprises transmitting the determined boosting factor to the UE, whereby the reception quality of transmission on the uplink control channel from the UE to the serving BS is enhanced by the UE boosting the control channel by means of the boosting factor.
Abstract:
There is provided a method for determining an offset to be used to extend the range of a first base station in a mobile communication network, the method comprising determining one or more characteristics of a mobile device; and determining offset to be used to extend the range of the first base station from the one or more characteristics.
Abstract:
Embodiments herein relate to a method in a network node (12, 14) for signalling Hybrid Automatic Repeat Request, HARQ, configuration for a common enhanced dedicated channel configuration in a radio communications network (1). The network node (12, 14) is comprised in the radio communications network (1) and serves a user equipment (10). The network node (12,14) determines a state of a HARQ process of a transmission time interval out of a number of HARQ processes for a common enhanced dedicated channel configuration. The state is defining whether the HARQ process is active or inactive. The network node (12, 14) signals the HARQ configuration for the common enhanced dedicated channel configuration by broadcasting a value representing the state of the HARQ process.
