Abstract: For an infinite number of transmit antennas at a base station (BS), matched filter (MF) precoding (a type of precoding used to perform SU-MIMO transmission) becomes optimal for performing spatial multiplexing. But observations have shown that precoding types for performing MU-MIMO transmission can perform significantly better than MF precoding for a realizable number of transmit antennas at the BS, even while using the simplest precoding types for MU-MIMO transmission. For large inter-cell interference typically encountered by user terminals (UTs) at or near the boundary of the cell served by the BS, MF precoding can still be used to eliminate or reduce the need for coordination among cells, which consumes network and back-haul resources.

Abstract: Embodiments include systems and methods for enabling a physical layer (PHY) link signaling channel between a network termination modem and a cable modem in a cable network. The PHY link signaling channel is embedded within the same multi-carrier channel as the data and enables PHY link up between the network termination modem and cable modern without involvement of higher layers (e.g., MAC). The PHY link signaling channel can be implemented in the downstream (from the network termination modem to the cable modem(s)) or in the upstream from a cable modem to the network termination modem. Embodiments are applicable to any known cable network, and particularly to cable networks implementing the DOCSIS and EPoC standards.

Abstract: A collocated device functioning as a configurator can use short and long button activations to enter a configuration state, open a timing window, and force client devices currently joined to a network to rejoin the network. If the collocated device functioning as a configurator is unconfigured, a short (or long) button activation can initiate a configuration sequence. A short button activation on that same collocated device, once configured, can cause the device to open a configurator timing window, during which one or more devices can be provided the information necessary to securely communicate on a network. A long (or short) button activation can be used to force all currently connected client devices, or rejoin the network using a new Service Set Identifier (SSID) or passphrase.
