Problems solved by technology

[0007] In areas with poor air interface quality, although the base station uses two transceivers as one transceiver to improve the air interface quality, but for wireless signals that can receive better quality without using PBT or diversity technology Users, such as users who are close to the BTS, use two transceivers as a transceiver to transmit data for these users, which will cause waste of system resources and reduce network capacity

Embodiment Construction

[0028] In the embodiment of the present invention, in order to avoid using at least two transceivers as a transceiver for those users who can receive better quality wireless signals without using PBT or diversity technology (such as distance A user whose BTS is closer) wastes resources caused by data transmission by a terminal, and provides a diversity transmission scheme, which may specifically include: first judging whether the quality of the air interface currently used by the terminal meets a preset condition; if the preset condition is met, Then use one transceiver to send data information to the terminal; if the preset condition is not met, use at least two transceivers to send data information to the terminal at the same time. Therefore, unnecessary use of at least two transceivers as one transceiver to transmit data is avoided, and system resources are saved as much as possible and network capacity is guaranteed while improving air interface quality.

Abstract

The present invention provides a diversity transmitting method, a device and a system thereof. The method comprises the following procedures in particular: determining whether the quality of the air interface used by the terminal currently obtains the prearranged condition; if the prearranged condition is obtained, transmitting the data information to the terminal with a transceiver; and if the prearranged condition is not obtained, transmitting the data information to the terminal with at least two transceivers simultaneously. The embodiment of the invention can realize that the number of the used transceivers can be adjusted according to the quality of the air interface used by the terminal currently flexibly, and thereby avoiding that at least two transceivers are taken as one transceiver for transmitting data to the subscriber which can receive wireless signal with better quality when the PBT or diversity technique is not adopted (such as the subscriber nearer to the BTS). The guaranteeing to the network capacity as possible is realized while the quality of the air interface is increased, and the system resource is saved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a diversity transmission method, device and system. Background technique [0002] In a wireless communication system, a base transceiver station (BTS, Base Transceiver Station) can implement wireless transmission with a mobile station (MS, Mobile Station) through an air interface. As wireless signals encounter various obstacles (such as buildings, undulating terrain, etc.) drop problem. [0003] In order to solve the above-mentioned problems under the independent transmission power condition of the existing BTS, so that users in areas with poor air interface quality can normally realize services, a power boost technology (PBT, PowerBoost Technology) can be used to increase the transmission power of the BTS at present, that is, Two transceivers (TRX) can be configured as one transceiver, so that the output power of the configured transceiver is greater tha...
