Problems solved by technology

However, DF-DC has no offloading gain compared to DC operation, and there is an additional cost of doubling the signaling overhead for DF-DC since both carriers may have to perform measurements and the serving cell changes independently
Furthermore, reducing the transmit power on the second carrier may degrade the performance of legacy UEs served on the reduced-power carrier

Embodiment Construction

[0034] In the context of this description, beamforming is proposed to alter and / or equalize and / or remove and / or reduce the UL / DL imbalance of a user equipment having a wireless communication connection with at least two nodes of a wireless communication network. The UL / DL imbalance may refer to a relationship between UL and / or DL ​​conditions for a user equipment with respect to one of the nodes and / or at least two nodes. The relationship may be parameterized in terms of one or more parameters, in particular signal strength, signal-to-noise ratio, transmitted power and / or received power (alternatively or additionally power density may be used). The relationship may be represented by a ratio of various parameters, eg a ratio of power transmitted by the user equipment to the first node to power received by the user equipment from the first node. Beamforming may be controlled to vary any of these conditions for UL and DL for any one of the nodes or for at least two of the at lea...

Abstract

The present disclosure relates to a method for beamforming in a wireless communication network, including determining an uplink / downlink (UL / DL) imbalance of a user equipment wirelessly connected or connectable to a first node of the wireless communication network. and determining the location of the user's device. The method also includes controlling the beamforming based on the determined UL / DL imbalance and the determined location utilizing at least an antenna arrangement controlled by and / or associated with the first node. Related methods, apparatus and arrangements are also disclosed.

Description

technical field [0001] The present disclosure generally relates to methods and apparatus for beamforming for or in wireless communication networks. Background technique [0002] The increasing global utilization of mobile broadband technologies has resulted in a significant increase in the amount of traffic that needs to be handled by mobile or wireless communication networks (eg WCDMA / HSPA). Therefore, technologies that allow network operators to manage their networks more efficiently are of great importance. Some approaches that would allow eg improved downlink performance would be to introduce support for 4-branch MIMO, multi-stream communication, multi-carrier deployment, etc. Since the spectral efficiency of each link is close to the theoretical limit, it can be considered to increase the spectral efficiency per unit area. Additional features on mobile networks are expected to provide a uniform user experience anywhere within a cell, eg via HSDPA or LTE based networks...
