Embodiment Construction

[0046] In a multi-user system such as WCDMA (Wideband Code Division Multiple Access), multiple users have communication links from user equipment (eg cellular phones or computers) to a base transceiver station BTS connected to a wired network.

[0047] figure 1 Examples of the invention are shown. In case of dense urban scenarios with buildings, multiple beams can be used to reach indoor and outdoor users. In the described embodiment, the user equipments UE1 to UE5 are divided into two groups: a first group of indoor users, which are close to the base station BTS and located in the inner cell 1; and a second group of outdoor users, which Located in outer cell 3.

[0048] More precisely, all users are managed by the same logical cell object in the network locally divided into two spatial volumes: inner cell 1 and outer cell 3,

[0049] - two first user equipments UE1 and UE2 are located in the inner cell 1 near the base station BTS,

[0050] - another user equipment UE3 (e....

Abstract

The invention relates to a base transceiver station BTS for communicating with a plurality of user equipments UE1, UE2, UE3, UE4, UE5 divided into at least two groups, said base station comprising: downtilt to reach at least two shifted static beams (Bi, Bo) of said user equipment UE1, UE2, UE3, UE4, UE5; a processing unit (25) connected to said transceiver chain (9) and having means for performing at least two linear complex combinations of uplink digital signals; - for receiving said uplink signals and for based on the quality of said uplink signals in beam flows (Fi, Fo) Instead, the components of the appropriate beam are selected for each user equipment.

Description

technical field [0001] The invention relates to a base station transceiver comprising an antenna element arrangement. The invention also relates to a method to optimize the capabilities provided by this multi-antenna arrangement. The goal is to optimize spectral efficiency using real-time analysis of information extracted within different beams used to manage traffic within the same logical cell. Background technique [0002] A radio communication network is equipped with a base transceiver station comprising an antenna adapted to cover a predefined cell of said network and to communicate with user equipment in this cell. For a given coverage requirement provided, assuming radio resources are scarce, different beams for a given spectral resource may be optimized in order to reduce densification requirements. [0003] Due to constraints on the location of the base stations, it is necessary to be able to optimize the radio cell geometry (Ii / (Ie+Ii), where Ii is the inter-cel...
