Problems solved by technology

However, in cellular networks, the prior art does not consider the technique of multi-user cooperative transmission
On the other hand, in multi-hop networks, there are many technologies about multi-user cooperative transmission, but these technologies are designed for the structure of multi-hop networks and cannot be directly transplanted into cellular networks

Embodiment Construction

[0033] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and unnecessary details and functions for the present invention will be omitted during the description to avoid confusing the understanding of the present invention.

[0034] figure 1is a flow chart of the multi-user cooperative transmission method 100 of the present invention. The multi-user coordinated transmission method 100 of the present invention can be applied to uplink transmission of a cellular communication system, and the cellular communication system includes a base station and a user equipment (UE). In the embodiment of the present invention, for multi-user coordinated transmission, UEs can be divided into source UEs and coordinated UEs. For example, when the channel quality between the UE and the base station is worse than a predetermined threshold TH1, the UE may request to perform coordinated multi-user transmission, and the ...

Abstract

The invention provides a multiuser cooperative transmission method executed by cooperative user equipment. The cooperative transmission method comprises the following steps of: receiving an indication of source user equipment corresponding to the cooperative user equipment, informing correspondence between the source user equipment and the cooperative user equipment; receiving one or more first transmission resources transmitted to the base station by the cooperative user equipment and allocated by the base station; allocating one or more second transmission resources transmitted to the cooperative user equipment by the source user equipment and allocated to the source user equipment on the basis of the first transmission sources; and forwarding data received from the corresponding source user equipment through the second transmission resources to the base station through the first transmission resources.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a multi-user cooperative transmission method, user equipment and a base station. Background technique [0002] With the development of cellular mobile communication technology, a large number of cellular network base stations have been erected, and cellular mobile communication devices have been widely used. A traditional cellular network adopts a method in which a base station directly communicates with user equipment and manages and controls all user equipment. In this cellular system, user equipment is completely invisible to each other. However, as people's requirements for cellular network system performance increase, traditional cellular networks encounter enormous challenges. In order to make full use of non-renewable wireless spectrum resources and deal with complex and changeable wireless communication environments, many technologies have been pr...
