Abstract: Embodiments herein relate to a method for performing continuous deployment and feedback between a radio network node and a Continuous Deployment server. The radio network node is configured to mimic a behavior of a mobile terminal towards a core network. The radio network node sends a message comprising a request to establish an end-to-end connection with the CD server to a core network node. The message further comprises a mobile identity identifying the radio network node as a mobile terminal. The radio network node receives an access bearer establishing a user plane connection between radio network node and the core network node over a user plane interface, from the core network node. The radio network node establishes a communication channel between the radio network node and the CD server over the user plane interface and an external packet switched network. The radio network node exchanges information between the radio network node and the CD server over the established communication channel.

Abstract: A method performed by a network node, for handling link adaption (LA) of a channel. The network node obtains a channel quality value for each Transmission Time Interval (TTI) in a set of TTIs. The network node estimates a probability that a specific channel quality will occur from the obtained channel quality values for the set of TTIs based on a distribution of channel quality values. The network node further determines a set of transmission parameters which optimizes a target function of LA, based on the estimated probability for the channel quality, wherein each set of transmission parameters is mapped to a channel quality which is required for a successful reception.

Abstract: A method performed by a network node for managing power of Cell Reference Symbols, CRS, wherein the network node operates one or more cells and the network node is configured to transmit the CRS in a first power mode. When the network node identifies a first cell which is not actively serving any UEs, which cell is also referred to as an empty cell, the network node reduces the power of the CRS in the first cell in relation to the first power mode. By reducing the power of the CRS, the overall interference of the CRS from the empty cell is reduced, thereby enhancing the performance in cells actively serving UEs.

Abstract: A method performed by a network node 110, for improving the performance of a handover of a user equipment (UE) 120, wherein the network node 110 serves a first cell 130 comprising one or more UEs 120. When the network node 110 has detected that a Signaling Radio Bearer (SRB) is determined to be scheduled for a UE 120 in handover from the first cell 130 to a second cell 131, the network node 110 increases the Control Channel Element (CCE) aggregation level in an OFDM-subframe to be sent to the UE 120 in a TTI related to the handover. By increasing the CCE aggregation level during a handover procedure, the effective coding rate of the PDCCH is increased, which leads to a more robust coding and reliability. Thereby the number of unsuccessful handovers and lost service is effectively reduced.

Abstract: For controlling radio transmission in a cellular communication network, a node of the cellular communication network determines a mapping between control channel elements of a downlink control channel and resources of an uplink control channel. The node determines a group of the resources of the uplink control channel which are mapped to a subgroup of the control channel elements. From this group of the resources, the node allocates resources to be used for transmission of uplink control information from a user equipment. Using a radio resource control message, the node may indicate the allocated resources to the user equipment. The allocated resources may be used as a Channel Selection set for transmitting feedback related to a secondary component carrier.
