摘要： There is provided mechanisms for determining average total transmission power for an antenna array configured for beamformed transmission within an angular coverage region. A method is performed by a control device. The method comprises determining bin-wise values of beamforming gain for a set of non-overlapping bins collectively covering the angular coverage region of the antenna array. The method comprises obtaining values of total transmission power of the beamformed transmission. The method comprises determining bin-wise values of average transmission power from the bin-wise values of beamforming gain and the values of total transmission power. The method comprises combining the bin-wise values of average transmission power into one value of average total transmission power for the antenna array.

摘要： Various embodiments of the present disclosure provide a method for remote interference detection. The method which may be performed by a first network node comprises determining a first subcarrier in a first resource of the first network node to transmit a reference signal for remote interference detection. The first subcarrier may be aligned with a second subcarrier in a second resource of a second network node. In accordance with an exemplary embodiment, the method further comprises transmitting the reference signal on the first subcarrier, according to a first reference signal sequence mapped to the first resource. The first reference signal sequence may be aligned, in an overlapped part of the first resource and the second resource, with a second reference signal sequence mapped to the second resource.

摘要： Disclosed are methods and apparatuses. The method implemented at a wireless device may comprise computing an average power for a bin covering a portion of a total solid angle covered by an antenna array of the wireless device by averaging a momentary power for the bin over a time period, wherein the momentary power is computed based on respective scheduled power of at least one beamforming transmission and respective antenna gain of the at least one beamforming transmission in the bin (302, 606, 702, 802, 902, 1002). The method may further comprise performing a back-off power feedback control for the bin based on the computed average power (304, 608, 708, 808, 908, 1006).

摘要： Methods, apparatus and computer programs are disclosed for controlling the output of a multiple-input, multiple-output, transmission point serving one or more groups of wireless devices. The MIMO transmission point utilizes respective pluralities of beam weights to transmit corresponding pluralities of beams to each group of wireless devices, with respective numbers of resources being allocated for transmissions to each group of wireless devices. One method comprises: determining an average output power of the transmission point over a period of time in a first direction; comparing the average output power to an output power reference value; determining a fraction of a pool of available resources for the allocation of data to be transmitted by the transmission point as a function of the comparison; for each group of wireless devices, determining beam gains in the first direction for each of the plurality of beams and weighting the number of resources allocated to the group of wireless devices according to the determined beam gains to obtain an effective number of resource blocks in the resources in the first direction to obtain an overall effective number of resources in the first direction; comparing the overall effective number of resources to the fraction of the pool of available resources; and scheduling data for transmission to the groups of wireless devices based on the comparison.
