Abstract: One embodiment is directed to a system that implements a downlink transmission mode that precodes sequences of symbols using a precoder matrix selected from a codebook. Linear transformations are performed on the sequences of precoded symbols using a distribution matrix. The distribution matrix is configured so that each of a plurality of precoder matrices provides perfect steering of transmit power to a corresponding one of a plurality of disjoint subsets of the antenna ports used for the downlink transmission mode. Also, the distribution matrix can be configured so that at least one precoder matrix provides peak power at all of the antenna ports used for the downlink transmission mode.

Abstract: A communication system includes a remote unit that exchanges radio frequency signals with mobile devices, at least some of the radio frequency signals comprising information destined for, or originating from, a mobile device, the remote unit being configured to perform first physical layer processing. A controller is separated from the remote unit by a switched Ethernet network, wherein data corresponding to the information is transmitted in frames between the controller and the remote unit. At least some of the data comprises baseband data that is transmitted in frequency domain. The controller and the remote unit are configured to transmit time stamp messages on the switched Ethernet network to synchronize a controller clock and a remote unit clock. The controller is configured to advance downlink subframe timing relative to the remote unit, when transmitting on the switched Ethernet network, based on a measured transport delay across the switched Ethernet network.

Abstract: One embodiment is directed to a communication system comprising a remote unit comprising a remote unit local clock and a controller communicatively coupled to the remote unit using a switched Ethernet network. The remote unit is configured to synchronize the remote unit local clock to a reference timing source using timing messages communicated over the switched Ethernet network with the remote unit. The communication system is configured to transmit the timing messages and baseband data so as to reduce a level of contention encountered by the timing messages in connection with being communicated over the switched Ethernet network.
