Problems solved by technology

It can be seen that when the number of user equipments is large (for example, the number of unscheduled user equipments N is large), the amount of calculation for trying to pair user equipments is very large, and the requirements for product implementation complexity are also relatively high

Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0017] Aiming at the problem of large amount of calculation in user equipment pairing processing in the existing VMIMO communication method, an embodiment of the present invention proposes a user equipment set classification scheme based on beam coverage, which can reduce the calculation amount of pairing processing in the VMIMO communication method.

[0018] figure 1 is a schematic flowchart of a user equipment pairing method according to an embodimen...

Abstract

The embodiment of the invention provides a method and a device for virtualizing a multiple input and multiple output communication. The method comprises the steps of determining sets to which the user devices in a sector belong; wherein, the sets to which the user devices belong comprise a first user set and a second user set, the user devices in the first user set are located in a beam coverage area of a first antenna group in the sector but are not located in the beam coverage area of a second antenna group in the sector, and the user devices in the second user set are located in the beam coverage area of the second antenna group in the sector but are not located in the beam coverage area of the first antenna group in the sector; when the scheduled user devices belong to the first user set, selecting the unscheduled user devices in the second user set to match; wherein, the matched user devices and the scheduled user devices use a same time frequency resource. For the user devices in the first sector, when the user devices match, the unscheduled user devices not located in the same set with the scheduled user devices are only selected to match, thereby saving the computing amount.

Description

technical field [0001] The embodiments of the present invention relate to the field of wireless communication, and more specifically, to a virtual multiple-input multiple-output communication method and device. Background technique [0002] VMIMO (VirtualMultiple-InputMultiple-Output) technology pairs user equipment (UE, UserEquipment), so that two paired user equipment can send data on the same time-frequency resource at the same time, and can share the same time-frequency resources to achieve space-division multiplexing of time-frequency resources, thereby increasing the capacity of the uplink system. [0003] When performing VMIMO communication, how to select a suitable user equipment for VMIMO pairing so as to maximize the overall system capacity is the primary consideration of the VMIMO communication method. When performing user equipment pairing in the existing VMIMO communication method, it is necessary to search among other unscheduled user equipments for the curren...
