Signal transmission method and devices

Abstract

The embodiment of the invention provides a signal transmission method and devices. In the technical scheme of deploying an indoor distribution system in the prior, in order to avoid multipath interference in signal transmission of a plurality of remote devices, the problems such as high space requirements, complicated engineering design, difficult implementation, and poor wiring design flexibilityand the like exist when deploying the plurality of remote devices; and the invention is used for solving the problems. The signal transmission method comprises the following steps: a network device determines a transmission delay corresponding to each remote aggregation device of at least one remote aggregation device; and the network device sets a standard delay according to the maximum transmission delay in the transmission delay corresponding to each remote aggregation device, wherein the difference between the standard delay and the transmission delay corresponding to the remote aggregation device is used as a buffer delay of the remote aggregation device, and the buffer delay corresponding to the remote aggregation device is used by a sending end to delay the buffer delay and then transmit a signal to a receiving end when the signal is transmitted between the remote aggregation device and the network device.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a signal transmission method and equipment. Background technique [0002] The indoor distribution system is a system that evenly covers the signal of network equipment to each indoor area through remote equipment, remote aggregation equipment and other equipment. In an indoor distribution system, uplink signal transmission passes through terminal equipment, remote equipment, remote aggregation equipment, and network equipment in sequence. Multiple remote equipment can be connected to the same remote aggregation equipment, and multiple remote aggregation equipment can be connected to the same Network device connection. [0003] In the indoor distribution system, the signal coverage of multiple remote devices may overlap. Take the uplink signal transmission as an example. In the overlapping area of ​​the signal coverage of multiple remote devices, the uplink signal ...
