A radio base station, RBS () of a wireless communication network indicates to a wireless device () where in the time and/or frequency domain to perform radio quality measurements. If the RBS () determines that one or more wireless devices () (including those that are idle) are in risk of performing deteriorated quality measurements, it refrains from scheduling beamformed downlink data in the time/frequency region where the wireless devices () perform quality measurements when the reference signals (e.g., Cell Specific Reference Signals, or CRS) are broadcast. This avoids deterioration of the RSRQ due to beamforming gain, and allows existing legacy features that rely on RSRQ to continue to function as originally intended. The restriction is only on beamformed data—the transmission of non-beamformed data in the relevant bandwidth is already accounted for in the use of RSRQ measurements.

Selective restriction in beamformed transmission scheduling

A method of a control node, operable in a communication network and comprising controlling circuitry configured to estimate quality of service (QoS) for geographical locations in the network is disclosed. The method comprises receiving () from a user operable in the network a request signal indicative of a starting point and a destination point, acceptable quality of service during transit of the user from the starting point to the destination point and transit time; determining () one or more routes from the starting point to the destination point based on transit time and on estimated QoS for a plurality of geographical locations of the one or more routes in view of the accepted QoS; providing () information of the determined one or more routes to the user; and dynamically updating () the determined one or more routes based on received information pertaining to experienced QoS associated with geographical locations pertaining to the determined one or more routes during transit of the user. Corresponding computer program product, and control node are also disclosed.

Route planning based on QoS requirements

Disclosed is a method for improving system performance in a wireless communication network comprising one or more network cells. Each network cell comprises one or more transmission points transmitting cell specific information. The method comprises determining () whether a first TRxP comprised in a first network cell fulfills a utilization criterion. When it is determined that the first TRxP fulfills the utilization criterion () the method further comprises gathering () utilization statistics associated with the first TRxP and/or with the first network cell, evaluating () the gathered utilization statistics and determining (), based on the evaluated utilization statistics, whether moving the first TRxP to a second network cell will improve overall system performance of the wireless communication network. Also disclosed are arrangements, transmission points, radio control functions and computer program products.

A method for assisting in a cell re-selection procedure in a cellular communication system comprises obtaining (S) of information comprising radio conditions and/or user equipment population related to at least a serving cell and optionally also related to at least one neighbor cell to the serving cell. The obtained information is compared (S) with a criterion for enforced cell re-selection procedure. If the criterion for enforced cell re-selection procedure is fulfilled by the obtained information, an enforcement of, or an action for increasing the probability for causing, a cell re-selection procedure of at least one user equipment within the serving cell is initialized (S). Devices for performing such a method are also disclosed.
