Patent ID: 11329699

Abstract:
A disturbance mitigation method of a communication element for a distributed antenna system is disclosed. The communication element is associated with two or more antenna elements of the distributed antenna system.The method comprises acquiring channel condition information associated with at least two of a plurality of wireless communication devices served by the communication element, and partitioning the plurality of wireless communication devices into at least two groups based on the acquired channel condition information.The method also comprises, for each of the groups, determining respective pre-coding weights based on the acquired channel condition information, wherein the respective pre-coding weights of different groups are determined according to different disturbance mitigation approaches.Furthermore, the method comprises transmitting a signal comprising respective symbols intended for corresponding ones of the plurality of wireless communication devices, wherein the symbols intended for wireless communication devices of each group are pre-coded using the determined respective pre-coding weights of the group, and wherein the pre-coded symbols of at least two of the groups are super-positioned to form the signal.Corresponding method of a wireless communication device is also disclosed, as well as corresponding apparatuses, communication element, distributed antenna system, wireless communication device and computer program product.
