Embodiment Construction
[0042] The technical solutions of the embodiments of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0043] The BS and RS in the network each maintain a frame for resource allocation for data reception and transmission, and perform corresponding operations according to the corresponding time in the frame structure of the frame. For example, the RS knows a certain period of time according to the frame structure of the RS frame. It is used to send data to the BS, and when the time is reached, the operation of sending data to the BS is performed and so on. In view of the disadvantages of waste of resources and poor flexibility of resource allocation in the prior art due to unreasonable frame structure construction, the embodiment of the present invention provides a method for creating a frame structure, without affecting other performances of the relay system, by using the The frame structure under TD...

A construction method for frame structure, an indication method for constructing frame structure and a network system therefor are provided in the embodiments of the present invention. The construction method includes the following steps: receiving management information, which is used to instruct a relay station to allocate resources, from a base station (100); constructing relay station frames according to the management information (101). In the construction method for frame structure, the indication method for constructing frame structure, and the network system therefor provided in the embodiments of the present invention, the relay station RS connects the two zones which are used to send data, and connects the two zones which are used to receive data, thereby reducing the mutual conversion time between sending and receiving data for RS, and enhancing the resource utilization ratio.
Description
technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a frame structure construction method, a frame structure construction instruction method, and a network system. Background technique [0002] Worldwide Interoperability for Microwave Access (WiMAX for short) is a wireless metropolitan area network technology based on the IEEE 802.16 standard. The air interface of IEEE 802.16 consists of a physical layer (PHY) and a media access control (MAC) layer. The MAC layer is further divided into three sublayers, namely Service-specific Convergence Sublayer (Service-specific Convergence Sublayer; Service-specific CS for short), MAC Common Part Sublayer (MAC Common Part Sublayer; MAC CPS for short) and security sublayer (SecuritySublayer; abbreviation: SS). figure 1 It is a schematic diagram of the logical structure of the existing WiMAX air interface interface, in which "BS" indicates a base station...
