Problems solved by technology

When the central unit fails, it will cause the entire network MIMO to be unavailable
[0007] (2) This is inconsistent with the current network architecture
But in the above architecture, the base station will lose the function of serving base station, because as mentioned above, the base station is only as the RF front end

Embodiment Construction

[0036] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The described embodiments are for the purpose of illustration only and do not limit the scope of the invention.

[0037] In order to clearly illustrate the present invention, two cases will be described separately: (1) single-user network MIMO; and (2) multi-user network MIMO.

[0038] Single User Network MIMO

[0039] Single-user network MIMO refers to a situation in which multiple base stations cooperate to provide services for one user equipment.

Abstract

The invention provides a method and a base station for supporting uplink network multiple input multiple output (MIMO). The method in the base station comprises the following steps: receiving a user signal from one or a plurality of user equipment containing the user equipment served by the base station and confirming channel state information between the base station and one or a plurality of user equipment; receiving the user signal and the corresponding channel state information from at least one of other base stations cooperatively serving the user equipment; and detecting and decoding the user signal together according to the user signal and the confirmed channel state information which are received by the based station and the user signal and the corresponding channel state information received from at least one of other base stations so as to obtain the data of the user equipment served by the base station.

Description

technical field [0001] The present invention relates to a distributed network architecture, and more specifically, to a method and a base station for supporting multiple-input multiple-output (MIMO) of an uplink network. Background technique [0002] It is well known that for future communication systems, such as cellular systems, the main capacity limitation is caused by inter-cell interference. Network multiple-input multiple-output (MIMO) schemes have been shown to be suitable for overcoming spectral efficiency limitations in system networks caused by co-channel interference. [0003] In network MIMO, the idea of ​​uplink network MIMO is that a group of base stations receive signals in a cooperative manner. Uplink network MIMO can be done by using joint detection and decoding among multiple base stations, which requires sharing user messages and channel state information among the cooperating base stations. [0004] However, the current network architecture cannot suppo...
