Method, system and device for allocating wireless resources

Abstract

The embodiment of the invention discloses a method for allocating wireless resources. The method comprises: the current condition of a wireless link or the current data in a buffer memory are monitored; the wireless resources between the wireless link and a relay link are adjusted according to the monitoring result; or the adjustment information of the wireless resources is transmitted to a base station according to the obtained monitoring result; and the base station adjusts the wireless resources between the wireless link and the relay link according to the adjustment information of the wireless resources. The embodiment of the invention also provides a system for allocating the wireless resources, a relay station and the base station. The dynamic adjustment of the wireless resources is realized by utilizing the technical scheme provided by the embodiment of the invention so that the wireless resources between the wireless link and the relay link are reasonably adjusted in time and the time delay of the data transmission and the waste of the wireless resources are reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more particularly, to a radio resource configuration method, system and device. Background technique [0002] With the continuous development of mobile communication technology, in order to meet the needs of users, a relay station is introduced into the original communication system to regenerate and amplify the wireless signal transmitted between the base station and the mobile terminal. The radio interface between the relay station (Relay, RN) and the base station (Donor eNodeB, DeNB) is called the radio link interface (UU interface), and the radio interface between the relay station and the user terminal (UE) is called the relay chain Road interface (Un interface). Usually, the wireless resources are shared between the wireless link interface and the relay link interface in a time-division multiplexing manner with a unit of 1 ms. Since the relay station uses the radi...

Problems solved by technology

However, since the number of UEs served by the relay station changes dynamically, and the channel quality and service requirements of the relay link interface are also constantly changing, when using this method to configure radio resources, if the radio link interface Allocating more wireless resources will easily cause downlink data to accumulate in the relay station, resulting in an increase in the buffer delay of the relay station, or even buffer overflow in the relay station; and if more wireless resources are allocated to the relay link interface, it may cause the buffering of the base station. The delay increases, and if the number of UEs served by the relay station is small or the business demand is small, it will also lead to waste of relay link interface resources

[0004] In addition, at present, the method of periodically adjusting the system information block (SIB) is adopted to allocate wireless resources between the wireless link interface and the relay link interface. The update of system information will wake up all the UEs that are resident and connected to the cell. Therefore, in a normal system, the update frequency of system information cannot be too fast to meet the rapid adjustment of wireless resources.

[0005] Therefore, in the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the wireless resources between the wireless link interface and the relay link interface cannot be adjusted in a timely and reasonable manner
