Abstract: A first base station provides radio communication service to user equipments, UEs, and a second base station that provides radio communication service to UEs in adjacent cell service area. The first base station receives cell range expansion, CRE, information from the second base station for expanding the size of the first cell and evaluates handover of one or more UEs with respect to the second cell based on the CRE information. In one embodiment, the second base station determines a CRE related configuration that includes the CRE information with respect to the first cell, sends the CRE information to the first base station. For example, the second base station may send a handover request including the CRE information to the first base station. The second base station also may consider CRE information in handover evaluation.

The affected cells receiving such a message can be adapted to use the information in the message when determining self-optimization parameters used for control purposes. Hereby, better response times can be achieved without reducing noise sensitivity.

Abstract: In a cellular radio system the power control status of a mobile station is used in the base stations to generate power control commands.

The radio base station is adapted to select power control method based on the power control status. Thus, a base station can select the most suitable power control improvement method, even during soft handover, thereby making make use of the advantages of different types of power control improvement methods.

Abstract: 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.

Abstract: In a method and a device for automated compensation for a cell/sector outage parameters of uplink power control are adjusted in order to tradeoff coverage versus quality. The uplink power control parameters can be continuously optimized in response to traffic and network characteristics thereby providing for an optimized performance degradation in cells surrounding the coverage hole.

Abstract: Embodiments herein relate to a method in a second network node (13,14) for detecting a short stay handover of a user equipment (11) in a second cell (16) in a telecommunication system (10).

The second network node sends, to a first network node (12,18), an indication in a message that a short stay handover has occurred when determined that the user equipment (11) is handed over to the third cell (17) before a time threshold, thereby enabling the first network node (12,18) to detect the short stay handover.

Abstract: The invention relates to a method for service aware scheduling of wireless resources in a wireless network. According to the inventive method, a service request for service delivery of a service type is received (51). A performance to value relationship for the service type is determined (52) and approximated (53) with a scheduling weight function associated with the service type.

Abstract: A method in a base station (110) for enabling the base station (110) to identify a neighbouring base station (120) is provided. A request is being sent (303) to a user equipment (130), commanding it to send an identification requesting message to the neighbouring base station (120). In response to reception of the sent identification requesting message, a neighbouring base station identifier that is associated with and identifies the neighbouring base station (120), is received (303).

By receipt of the neighbouring base station identifier, the base station becomes aware of and is enabled to contact, or connect with, the neighbouring base station more directly, without the need of doing it through the user equipment. This can be done at some later point in time, for example in order to request the neighbouring base station to perform handover measurements with regard to the same or another user equipment.
