Network node () and method () in a network node (), for admission control of a request for a radio access bearer to be received from a user equipment (). The method () comprises monitoring () the achievement of quality of service requirement of an admitted radio access bearer, detecting () when the quality of service requirement of the admitted radio access bearer is not achieved, assessing () a reason why the quality of service of the admitted radio access bearer is not achieved, and determining () admittance of a further request for radio access bearer, based on the reason why the quality of service of the admitted radio access bearer is not achieved.

Method and network node for determining admittance based on reason for not achieving quality of service

Methods and network devices estimate power of signals received from a user equipment in a sector of a cellular network cell using a data signal, which is not a predetermined reference signal. An exemplary method includes (1) saving a data signal received from the user equipment in a first sector of the cellular network cell, (2) acquiring a reference signal that corresponds to the data signal as received in a second sector of the cell and demodulated, and (3) comparing the saved data signal and the reference signal to estimate power of the data signal as received in the first sector.

The present disclosure relates to a method and an access nodefor reducing interference The access nodecommunicates with a user equipmentover a wireless access interface a i in a wireless communication networkThe method comprises the actions of obtaining (S) timing information indicative of one or more periods when a relay nodecommunicates with a donor nodeover a wireless backhaul interface b h i, and identifying (S) that the user equipmentis receiving a signal from the relay nodecommunicating with the donor nodeover the backhaul interface b h I that is stronger than a predetermined threshold, and in response to identifying that the user equipmentis receiving a signal from the relay nodethat is stronger than a predetermined threshold, prioritising (S) communication between the access nodeand the identified user equipmentvia the access interface a i during the periods when the relay nodecommunicates with the donor nodeover the backhaul interface b h i.

Reduction of interference in relay systems

A network node () of a radio access network () comprises a scheduler () configured to provide an allocation of an uplink resource to an indoor wireless terminal () in communication over an air interface with the radio access network. The allocation of the network node is made in coordinated manner with resource allocation of another network node whereby any interference by reason of allocation of same uplink resource must be with another indoor wireless terminal served by the another network node. Preferably the another network node is a network node which serves a neighboring or adjacent cell.
