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 two DASs each, provided inside the physical structure, for indoor MIMO communication with the user equipment located inside the physical structure.

摘要： Throughput conditions limited by multiplicative noise may be improved by distributing a transmission power across MIMO data streams communicated between MIMO communication nodes. In particular, the transmission power is distributed based on knowledge at the transmitter of the MIMO channel to decrease the transmission power allocated to one or more of the data streams associated with a dominant signal path relative to the transmission power allocated to one or more data streams associated with a weaker signal path to increase at least one of a quality and a throughput condition of the MIMO channel.

摘要： The MIMO method and apparatus disclosed herein improve throughput conditions limited by multiplicative noise by reducing the gain of the data streams associated with one or more dominant signal paths between MIMO communication nodes. As used herein, multiplicative noise refers to any noise dependent on or proportional to a signal strength at a transmitting node and/or a receiving node of a wireless communication network. An additional method and apparatus are included for determining that multiplicative noise limits the throughput conditions.

During a third mode of operation, all antenna radiation lobes are directed towards the second donor node. A first polarization is associated with each lobe directed towards the second donor node during the second mode of operation and a second polarization is associated with each lobe directed towards the first donor node during the second mode of operation.

摘要： Embodiments herein relate to a method in a first communication node (201) for estimating pre-coding weights for transmission on a radio channel (205) between the first node (201) and a second communication node (203) in a communication network (200). The first node (201) comprises at least two transmit antennas. Each transmit antenna is configured to transmit on each of at least two sub-bands. The first node (201) obtains at least two pre-coding reports. Each pre-coding report is for a different time instance. Each pre-coding report comprises pre-coding weights or indications to pre-coding weights. The pre-coding weights are associated with each transmit antenna and with each sub-band. For each transmit antenna, the first node (201) estimates pre-coding weights for at least one of the sub-bands based on the pre-coding weights in the obtained pre-coding reports. The estimated pre-coding weights are different from a most resent of the obtained pre-coding reports.
