Problems solved by technology

Assuming that the persistently assigned resource is R, the current method of de-persistently assigning leads to a waste of N*R channel resources. At the same time, since the time interval of a retransmission is T, it also introduces (N-1 )*T time delay, which greatly reduces the efficiency of the system

Embodiment Construction

[0035] In order to make the purpose, technical means and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] In the current continuous assignment method, the de-assignment process initiated by the terminal cannot be recognized by the network in real time, and the persistently assigned resources are released, so resources are wasted and delays are caused. Based on this, the basic idea of ​​the embodiment of the present invention is: through the terminal sending a displayed de-assignment message, the network can recognize the de-assignment process initiated by the terminal in real time, so as to achieve the purpose of releasing persistently assigned resources in time, Improve system performance.

[0037] figure 2 It is an overall flow chart of the method for releasing reverse persistent assignment resources in the embodiment of ...

Abstract

The embodiment in the invention discloses a method for releasing reverse sustainable assignment channel resource which is characterized in that the method comprises the following processes: the terminal sends de-assignment channel information pointing to the reverse sustainable assignment channel resource to the network side; after determining that the received information is the de-assignment channel information, a network side sends confirmed information to the terminal and releases the reverse sustainable assignment channel resource; when receiving the confirmed information sent by the network side, the terminal releases the reverse sustainable assignment channel resource. The method in the embodiment can timely release the reverse sustainable assignment channel resource, thus saving system resource and improving the performance of the system. The embodiment in the invention also discloses a system of releasing the reverse sustainable assignment channel resource, a terminal and a resource releasing device.

Description

technical field [0001] The present invention relates to packet scheduling technology in mobile communication, in particular to a method, system, terminal and equipment for releasing reverse persistent assignment resources. Background technique [0002] Mobile communication system is one of the hotspots in communication technology research at present. With the evolution and development of mobile communication technology, broadband and IP packet switching are the main development trends. In the current research on 3G, 3.5G and 4G, higher throughput and higher spectral efficiency have become one of the research focuses. [0003] There are many ways to achieve higher capacity and higher spectral efficiency, including the introduction and realization of various diversity techniques, one of which is to increase the effective bandwidth for data transmission in the communication bandwidth more effectively. In a mobile communication system, control channels are usually used to carr...
