摘要： Embodiments herein relate to a method performed by a first transmission point (12) out of at least two transmission points for estimating a channel quality gain of a wireless device (10) served by the first transmission point (12) in a wireless communication network (1). The first transmission point (12) coordinates transmissions with a second transmission point (13) out of the at least two transmission points in the wireless communication network (1). The first transmission point estimates the channel quality gain based on whether a first cell specific reference signal, CRS, configuration of the first transmission point (12) is using radio resources for a first CRS that are colliding or not with radio resources used for a second CRS of a second CRS configuration of the second transmission point (13) in the wireless communication network (1), and a utilization of frequency resources by the second transmission point (13).

摘要： Disclosed is a network node and a method performed by a network node in a wireless communication network for determining signal to noise ratio of a signal received at a receiver from a first mobile station, which signal may include both noise and interference. The method comprises obtaining a plurality of measured noise and interference power values, IN values, of signals received at the receiver in one or more frequency sub-bands, determining IN for a lowest X percentile of the measured IN values, and applying the determined IN for the lowest X percentile as a measure of the noise. The method further comprises obtaining a measured signal strength value for a signal received at the receiver from the first mobile station, and determining SNR for the signal from the first mobile station by applying the determined noise measure.

摘要： Embodiments herein relate to a method implemented by a wireless communication device (10). The wireless communication device (10) transmits data to a radio node (12) of a wireless communication network (1). The wireless communication device (10) monitors for a positive acknowledgement or a negative acknowledgement of the data from the radio node (12). The wireless communication device (10) retransmits the data to the radio node (12) when said monitoring indicates reception of a negative acknowledgement of the data. The wireless communication device (10) refrains from retransmitting the data to the radio node (12) when said monitoring indicates reception of a positive acknowledgement of the data. The wireless communication device (10) also refrains from retransmitting the data to the radio node (12) when said monitoring indicates neither reception of a positive acknowledgement of the data nor reception of a negative acknowledgement of the data.

摘要： A network node and a method performed thereby for controlling operation of a low power node are provided. The network node and the low power node are operable in a wireless communication network, wherein the low power node has at least two modes of operation, an active mode where the low power node is in full operation, and a passive mode where the low power node is discoverable by wireless devices in the network but not available for initial access or incoming handovers. The method comprises receiving (210) a measurement report from at least one wireless device, the measurement report comprising a measurement related to the low power node; and determining (220) the operation mode of the low power node based on the received measurement report. The method further comprises when the current operation mode of the low power node is passive and the determined operation mode is active, changing (230) the operation mode of the low power node to active mode.

摘要： Embodiments herein relate to a method in a radio base station (12) for scheduling a radio resource to a first user equipment (10). The radio base station (12) is comprised in a radio communications network and controls a number of radio resources to be scheduled for communication to a number of user equipments (10,11). The number of user equipments comprises the first user equipment (10) and being served by the radio base station (12). The scheduling is based on channel quality of channels used by the respective user equipments. The radio base station (12) estimates a first channel quality of a channel used by the first user equipment (10). The radio base station determines a pathloss between the first user equipment (10) and the radio base station (12), and computes a second channel quality of the channel based on the estimated first channel quality and the determined pathloss. The radio base station (12) then schedules a radio resource out of the number of radio resources to the first user equipment (10) based on the second channel quality.
