Embodiment Construction

[0029] In order to achieve mutual compatibility between IEEE802.16m (hereinafter referred to as 16m) and IEEE802.16e (hereinafter referred to as 16e), it is necessary to further design the allocation of 16m subframes and 16e subframes, and how 16m terminals obtain control messages . In addition, the power consumption of the 16m terminal based on the three-layer frame structure can be further reduced by reasonably setting the frame control information. The present invention can achieve the above purpose, thereby achieving compatibility.

[0030] An embodiment of the present invention provides a method for sending a frame control message, which is applied to a system compatible with 16e and 16m, wherein the system includes a base station and a terminal.

[0031] like figure 2 As shown, the frame control information method according to the embodiment of the present invention includes: step S202, the base station notifies the terminal of the subframe allocation information indi...

Abstract

The invention discloses a method for sending a frame control message, which comprises the step of notifying sub-frame assignment information indicative of sub-frame assignment in a superframe to a terminal through a superframe control head by a base station. By using the method, the invention can satisfy requirements on performances of time delay reduction, terminal power saving, and the like based on the terminal of the next generation wideband access WiMAX system backwards compatible with the prior WiMAX system.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method for sending a frame control message. Background technique [0002] Orthogonal Frequency Division Multiplexing (OFDM) technology can greatly reduce the sensitivity of the system to frequency selectivity of multipath fading channels by converting high-speed transmission data streams into low-speed parallel transmission data streams. In addition, OFDM further enhances the ability of the system to resist inter-symbol interference by introducing a cyclic prefix. At present, OFDM technology has been widely used in the field of wireless communication due to its high bandwidth utilization rate and simple implementation. [0003] A Worldwide Interoperability for Microwave Access (WiMAX) system based on Orthogonal Frequency Division Multiple Access (OFDMA) is a system using OFDM technology. [0004] At present, with the continuous progress of wireless communication...
