Embodiment Construction

[0038] For ease of illustration and not limitation, specific details such as specific nodes, functional entities, technologies, protocols, standards, etc. are set forth in the following description in order to provide an understanding of the described technologies. However, it will be apparent to those skilled in the art that other embodiments may be practiced without the specific details disclosed below. For example, although example embodiments are described in the context of multi-sector omni radio base stations and multi-sector base stations, the disclosed techniques are also applicable to other types of multi-antenna arrangements and indoor and outdoor applications. In other instances, detailed descriptions of well-known methods, devices, techniques, etc. are omitted so as not to obscure the understanding of this description with unnecessary detail. The individual functional blocks are shown in the figures. Those skilled in the art will understand that the functions of t...

Abstract

A base station includes multiple sector antenna units. Each sector antenna unit has an antenna for receiving a carrier signal associated with an antenna frequency in an available frequency band. The base station is converted between a multiple sector base station configuration and a multi-sector, omni-base station configuration. In a diversity base station implementation, each sector antenna unit receives a diversity signal from a first sector, and the second diversity antenna unit receives a diversity signal from a second different sector. If one sector antenna unit does not perform properly so that one of the sector diversity signals is lost or corrupted, the other sector diversity signal is still useable. The base station may be reconfigured to power-down at least some part of the transmit side without having to power-down some or all of the receive side.

Description

technical field [0001] The technical field relates to omni-directional base stations and multi-sector base stations that include multiple sectored antennas. Background technique [0002] An omni-directional base station is a base station configured to use omni-directional antennas, and a sectored base station is configured to use multiple (two or more) sectored antennas. Figure 1A A single cell area of ​​a base station (BS) with omnidirectional antennas is shown. The omnidirectional antenna radiates 360 degrees to provide coverage of the entire cell area. Figure 1B A single cell area of ​​a base station (BS) with three sectored antennas is shown. A three sector base station is a common sector configuration, but more or fewer sectors can be used. In this case, the cell area is divided into three, where each sector antenna (compared to an omnidirectional antenna) has a narrower beam that radiates to provide coverage over its sectoral area of ​​approximately 120 degrees. ...
