Embodiment Construction

[0048] In view of the existing technology, due to the new type of room distribution system, the signal of each remote unit is superimposed and transmitted back to the baseband unit, resulting in the superposition of the noise of the return signal at the front end of each remote unit, and the superimposed signal received by the baseband unit The noise floor rises, which affects the communication quality. The embodiment of the present invention uses the baseband unit to accurately determine the effective receiving resources of each remote unit within the jurisdiction at the current scheduling time, so as to control the reception of each remote unit at the current scheduling time. Only the effective transmission resources are turned on for the transmission of uplink signals, and the signals on the invalid transmission resources are turned off, thereby effectively reducing the noise superposition of the backhaul signals at the front end of each remote unit, effectively suppressing t...

Abstract

The invention relates to the technical field of wireless communication, and discloses an uplink signal transmission method and device, which are used to suppress background noise and improve communication quality. The method is as follows: the baseband unit determines at least one terminal for uplink scheduling at the current scheduling time, and based on the remote unit accessed by the at least one terminal and the uplink resources allocated for the at least one terminal, determine the terminal within the jurisdiction of the baseband unit The effective transmission resources of the remote units at the current scheduling time, the baseband unit controls the remote units within the jurisdiction to transmit uplink signals on the corresponding effective transmission resources. In this way, it can effectively prevent the baseband from receiving background noise superimposed signals, thereby improving the accuracy of suppressing background noise, reducing the implementation complexity of suppressing background noise, and ultimately improving communication quality to a large extent.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for transmitting an uplink signal. Background technique [0002] With the rapid development of mobile Internet, indoor data services are growing explosively, and it is particularly urgent to achieve indoor deep coverage and capacity coverage. The new indoor distribution system is widely used in indoor coverage because it uses network cable backhaul power supply to facilitate rapid deployment, and uses low-power multi-antenna coverage to effectively achieve uniform signal coverage. It can effectively achieve indoor deep coverage and capacity coverage. [0003] like figure 1 As shown in , it is a simple schematic diagram of the network topology of the existing new indoor distribution system. Cell 0 is composed of one baseband unit connected to three remote units, that is, cell 0 is covered by three remote units cooperatively to increase ...
