摘要： The invention relates to methods and arrangements for handling handover-related parameters. A radio base station of a mobile communications network is arranged to serve at least a first cell, and to make handover decisions based on handover-related parameters. The radio base station comprises means for receiving handover related feedback from a radio base station serving a second cell after handover of a UE from said first cell to said second cell; means for using the handover related feedback received from the base station serving said second cell to adjust the handover-related parameters; and further by means for sending handover related feedback to a radio base station serving a second or another cell after handover of a UE to said first cell from said second or another cell.

摘要： Control of uplink transmit power for a first mobile station operating with scheduled uplink data transmissions. A change in uplink scheduled status for the first mobile station is detected (301). Filtering of uplink interference measurements for the first mobile station is adapted (302) to account for the detected change in uplink scheduled status for the first mobile station. Alternatively a change in uplink scheduled status for a second mobile station is detected and a current filtering state for filtering of uplink interference measurements for the first mobile station is adjusted by applying an estimated expected change in interference associated with the detected change. A signal quality for uplink transmissions from the first mobile station is determined (303) based on measurements of received signal strength from the mobile station and the filtered uplink interference measurements. An uplink transmit power command is generated (304) for the first mobile station based on a comparison of the estimated signal quality to a signal quality target.

摘要： A received signal of interest is processed by determining timing of interference spikes in the received signal of interest. Receivers can determine when certain types of interference spikes are expected to occur, e.g., based on when different users are scheduled to transmit data during an overlapping portion of the same transmission time interval. The interference timing information is used by the receiver to soft scale signal values recovered from the received signal of interest that coincide with the interference spikes separately from remaining ones of the signal values. This way, fast changing interference power can be accurately tracked during periods of known interference spikes while also accurately tracking slower changing interference power during other periods.

摘要： The present invention relates to handover procedures in a cellular communications system (1). The cells (10-70) of the system (1) are divided into multiple handover-related classes based on their respective radio coverage characteristics. Each such cell class is then associated with a unique handover parameter or a unique set of parameters that are used in handover procedures involving the cells (10-70). The parameter values are adapted for the radio coverage characteristics of each cell class in order to generate a suitable handover region size of the cells (10-70). The handover parameters are used together with user equipment-assisted signal quality measurements for triggering the handover procedures.

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 method in a base station for assisting a network management unit in managing a cellular network is provided. The base station determines a status of the cellular network. The status affects a measurement of a quality of a radio channel between the base station and a user equipment comprised in the cellular network. The measurement is to be performed by the user equipment. The base station receives a feedback report from the user equipment comprising the measurement. The base station evaluates a validity of the measurement based on the determined status. The base station sends a report to the network management unit. The report comprises an indication of the measurement and an indication of the validity, thereby assisting the network management unit in managing the cellular network.

摘要： A method, in a base station, provide a mechanism for observing random access performance in a Long Term Evolution network. The random access performance is defined by an access delay. The access delay is a delay from the initial random access attempt until access is granted. The method comprises receiving a respective report from a plurality of user equipment, where each of the respective user equipment has performed a random access process and received a random access grant. The reactive report includes access delay related random access information. The method includes determining a respective access delay, based on each of the access delay related random access information. The determined access delays are used for the estimation of access delay statistics. The random access performance is observed based on the access delay statistics.
