发明名称 Apparatus and method for wireless network enhancement via variable down tilt
摘要 Apparatus and methods for controlling antenna down tilt in a mixed coordinated/non-coordinated network include receiving one or more input signals defining a waveform to be transmitted, for determining a tilt angle state to be applied to the antenna based on the one or more input signals, and for transmitting a tilt control signal if the determined tilt angle state differs from a current tilt angle state associated with the antenna.

主权项 1. A method for controlling antenna down tilt in a mixed coordinated/non-coordinated network including at least one base station that mixes transmissions of coordinated signals that are synchronized with one or more adjacent base stations and transmissions of non-coordinated signals that are not synchronized with the one or more adjacent base stations, the method comprising: receiving by the at least one base station, one or more input signals defining a waveform to be transmitted via an antenna of the at least one base station; determining a type of the waveform defined by the one or more input signals, comprising determining whether one of the one or more input signals is a single-cell unicast waveform, a multi-cell single frequency network (SFN) unicast waveform, or a broadcast SFN waveform; determining a tilt angle state to be applied to the antenna based on the type of the waveform in response to receiving tilt control information from a network control entity, wherein the tilt control information comprises a timing and a down tilt state received or derived from at least one of a multimedia broadcast multicast service coordination entity or a mobility management entity; and transmitting a tilt control signal to adjust the down tilt of the angle if the determined tilt angle state differs from a current tilt angle state associated with the antenna.
