The receiving unit includes: a network interface which obtains information relating to a time-varying layout of a silent resource element (RE) grid; an electronic memory having code in communication with the network interface which stores the information; and a processing unit in communication with the electronic memory that takes a presence of a silent RE grid into account in the reception of a control or a data channel.A method for a receiving/transmitting unit of a wireless network for facilitating noise and interference measurements on an air interface is described. Information relating to a time-varying layout of a silent resource element (RE) grid is obtained and a presence of a silent RE grid is taken into account in the reception of a control or a data channel.

摘要： Method and apparatus for enabling accurate link quality estimation of a wireless link between a sending node (400) and a receiving node (402). When the sending node receives link state reports from the receiving node, it estimates the current state of the wireless link. The sending node also determines a measurement adjusting parameter if the link state reports are deemed inaccurate in relation to the estimated link state, based on a deviation between the received link state reports and the estimated actual link state. The sending node then sends the determined measurement adjusting parameter to the receiving node, and the receiving node provides a link state report based on signal measurements adjusted by the measurement adjusting parameter. The adjusted link state report can then be used for link adaptation of the wireless link and/or for packet scheduling decisions.

摘要： The object of the present invention is to achieve a solution for handling the increased PAPR that is introduced by the FD and/or TD multi-antenna processing. This is achieved by isolating the PAPR increase to one, or a few antennas, that are matched with more powerful PAs, whereas the remaining antennas may use simpler/smaller PAs amplifying signals with smaller PAPRs.

摘要： A method and an arrangement in a radio network node for adapting transmission power of resource elements for demodulation reference signals, referred to as “reference elements” are provided. The radio network node is configured for multiple-input multiple-output transmission, referred to as “MIMO transmission”, to a user equipment. The MIMO transmission comprises at least three layers. Two consecutive subcarriers of a resource block carry at least three reference elements. A first subcarrier of the resource block carries data elements. The radio network node adapts transmission power of said at least three reference elements such that an average transmission power, over said two consecutive subcarriers, of said at least three reference elements is equal to a transmission power, for the first subcarrier, of the data elements for said at least three layers. The radio network node uses the adapted transmission power to transmit, to the user equipment, said at least three reference elements.
