摘要： A node in a wireless communication system comprising an antenna array with at least a first antenna function and a second antenna function. The node further comprises a first radio chain and a second radio chain, where each antenna function is connected to a base band via a corresponding radio chain. Each radio chain comprises an oscillator, a splitter and a multiplexer, each oscillator being arranged to feed a signal with a unique frequency band to the splitter in the same radio chain. The splitter is arranged to divide the signal into at least two signal parts and feed each part to the multiplexer of each radio chain such that each multiplexer in the node receives signal parts from each splitter in the node. The splitter is arranged to weight the division of the signal into the signal parts in dependence of the frequency bands fed by each oscillator.

摘要： One way to increase robustness against beam pair link failure is by transmitting downlink (DL) control signaling (e.g., PDCCH) in more than one beam. That is, one way to mitigate BPLF is for the UE to receive DL control signaling over both a first BPL (e.g., active BPL) and a second BPL (e.g., monitored BPL) but with larger duty cycle for the second BPL compared to the first BPL. For example, the control signaling can be scheduled every slot on the first BPL and scheduled every Nth slot on the second BPL. In this way, in case the first BPL is blocked and the UE cannot decode the control signaling on the first BPL, the UE can receive control signaling transmitted on the second BPL.

摘要： The invention relates to a wireless outdoor-indoor multiple-input multiple-output (MIMO) communications system for communicating with user equipment located inside a physical structure such as a building. The MIMO communication system is comprised of a node having at least two node antennas, wherein the node is configured for line of sight (LOS) wireless MIMO communication with at least two outdoor-indoor repeaters, and of at least two outdoor-indoor repeaters adapted for LOS wireless MIMO communication with the node. The repeaters have at least one repeater antenna each, provided outside the physical structure, for LOS MIMO communication with the node and at least one leaky cable each, provided inside the physical structure, for indoor MIMO communication with the user equipment located inside the physical structure. The repeaters are provided outside on the same physical structure and spaced well-apart, and each leaky cable of each repeater is provided such that they provide the same indoor coverage of the same interior space in the physical structure.

摘要： The method and apparatus disclosed herein improve throughput conditions limited by multiplicative noise by determining precoder weights for each data stream communicated between a MIMO transmitter node and a MIMO receiver node. The precoder weights are determined based on information derived from non-precoded reference symbols to decrease the energy allocated to the dominant signal path relative to the energy allocated to the non-dominant signal paths.
