Information processing method in home base station network

Abstract

The invention discloses an information processing method. According to the information processing method, a macro base station and a family base station send training sequences to a relay and a family user respectively, the relay and the family base station send training sequences to a macro user and the family user respectively, and estimation channels from the macro base station to the relay, from the family base station to the relay, from the macro base station to the family user, from the family base station to the family user, from the relay to the macro user, from the family base station to the macro user and from the relay to the family user can be obtained through channel estimation; the macro base station, the family base station and the relay calculate transmission beam forming matrixes of the macro base station, the family base station and the relay by using an iterative algorithm according to estimation channels; the macro base station and the family base station conduct linear processing on transmission signals and broadcast the transmission signals, the family base station user and the relay receive information, the relay conducts linear processing on the received information and broadcasts the received information, and the family base station conducts linear processing on newly transmitted signals and broadcasts the newly transmitted signals; and the macro user and the family user receive the transmission signals respectively. The method effectively restrains the cross-layer interference.

Description

technical field [0001] The present invention relates to the technical field of home base stations and MIMO (Multiple-Input Multiple-Output, multiple-input multiple-output) relays for wireless communication, and in particular to an information processing method in a home base station network that can effectively suppress cross-layer interference. Background technique [0002] With the continuous development of society, people's requirements for communication quality and speed are constantly improving. Studies have shown that 50% of voice services and 70% of data services take place in indoor environments. The data rate of the voice signal is low, and the quality of the signal is not high, while the data signal requires high signal quality to provide high-speed services. In order to improve indoor coverage and communication quality, femtocells emerge as the times require. The home base station has a small coverage area and can work with lower power to meet the requirements o...
