Frequency Band Selection in Heterogeneous Networks

Abstract

The invention discloses a small cell base station, a method, a computer program product and a wireless communication network. A small cell base station is deployable in a wireless communication network in which a macro base station provides a first area of ​​radio coverage using a first frequency band and a second area of ​​radio coverage using a second frequency band, the first area of ​​radio coverage including a plurality of angularly spaced first radio wave beams, a second area of ​​radio coverage including at least a second radio wave beam configured to radiate from a macro base station between adjacent angularly spaced first radio wave beams Out, the small cell base station includes: transmission logic operable to provide a third area of ​​radio coverage using a small cell frequency band, the small cell frequency band including one of the first frequency band and the second frequency band; receiving logic operable to measure from signal quality of transmissions received by the macro base station using the first frequency band and the second frequency band and identifying one of the first frequency band and the second frequency band having the highest signal quality as an excluded band; and transmission band selection logic operable to select Frequency bands other than the excluded frequency band are regarded as small cell frequency bands. Through this method, the macro base station and the small cell base station can share the frequency band. The overall performance of the wireless communication network is improved by excluding frequency bands with the highest signal quality and excluding high-quality frequency bands from frequency bands being used by small cell base stations.

Description

technical field [0001] The present invention relates to small cell base stations, methods, computer program products and wireless telecommunication networks. Background technique [0002] Wireless telecommunication systems are known. In such systems, a wireless communication device (eg, a mobile telephone) is operable to communicate with a base station provided by a network provider. [0003] In known wireless telecommunication systems, radio coverage is provided to network-connectable devices, such as mobile phones, or wireless devices such as iPads or other similar tablets, within an area called a cell. A base station is placed in each cell to provide radio coverage. Typically, the network-connectable devices in each cell are operable to receive information and data from and transmit information and data to the base station. [0004] A user equipment roams in a wireless communication system. A base station is usually provided to support an area of ​​radio coverage. Ma...
