Problems solved by technology

In this way, since multiple antennas share one address code, the antennas lack independence, and the space gain brought by multiple antennas is not fully utilized, which limits the ability to divide users or services on antennas

Embodiment Construction

[0047] In this section of the detailed description, there is shown and described the preferred embodiment of the invention by way of illustration only of the best mode contemplated by the inventors for carrying out the invention. As will be realized, the invention may be modified in various obvious respects without departing from the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0048]In the technical solution of the present invention, in order to make full use of the space gain brought by multiple antennas, each antenna in the multiple antennas of the base station is assigned its own antenna address code, and indicates to the mobile terminal the antenna address code of the antenna it uses; the mobile terminal according to The antenna address code indicated by the base station is demodulated to obtain the data sent by the base station on the antenna allocated to it. In this way, since each antenna in t...

Abstract

The invention discloses a technical project which uses multiple antennas and realizes synchronization in a multi-antenna environment. The invention distributes an antenna address code to each antenna in a base station and denotes the antenna address code of the used antenna to a mobile external. According to the antenna address code denoted by the base station, the mobile terminal demodulates andobtains the data on the antenna distributed by the base station. In the technical project of the invention, because each antenna in the multiple antennas has respective antenna address code, the mobile terminal can distinguish each antenna and get the corresponding data from the antenna used by the terminal in addition to making the use of the space gain brought by the multiple antennas by denoting the antenna address code of the antenna used by the mobile terminal to the mobile terminal. At the same time, the requirement that consumers or operations are measured off on the antennas can be satisfied.

Description

technical field [0001] The present invention relates to multi-antenna technology, especially a method for base stations using multi-antennas, a method for realizing synchronization of mobile terminals in a multi-antenna environment, a system using multi-antennas, a base station using multi-antennas and a Synchronized mobile terminals in a multi-antenna environment. Background technique [0002] Multi-antenna technology includes multiple input and multiple output (MIMO, Multiple Input and Multiple Output) antennas, smart antennas, distributed antennas, etc., and is one of the research hotspots in the fourth generation (4G) communication standards. It can effectively improve system performance and capacity, suppress co-channel interference and medium interference, and obtain diversity gain against multipath fading. [0003] For scenarios where there are multiple antennas at the base station, the original antenna address code usage scheme is still used in the prior art, that i...
