Embodiment Construction

[0048] Such as image 3 As shown, the system will selectively send control information in special time slots 310 of some subframes. In order for the receiver to flexibly select a subframe with control information to receive the control information, it is necessary to design a method to inform the receiver whether a certain frame contains control information.

[0049] still with image 3 The subframe structure of the shown TD-SCDMA dedicated carrier is described as an example, but those skilled in the art know that this is just an example of the TD-SCDMA frame structure, and the present invention is not limited to this specific example, but can be extended into other time-division system frame structures including special time slots (with downlink control information).

[0050] subframe 201 0 As an example, its conventional dedicated carrier slot 302 0 、302 2 -302 7 All have the same structure, including a reference symbol part and an information data part. A reference s...

Abstract

The invention relates to a time division system frame structure with control information indication, and an arrangement method, a processing method and a device thereof. The arrangement method comprises the following steps: a reference sequence is used as a basic code of a reference mark in at least one conventional time slot of at least one subframe, wherein, the reference sequence is selected from a plurality of cyclic shift sequences with different cyclic shift numbers in the same fundamental sequence, each cyclic shift sequence respectively represents a control information indication, andeach control information indication is corresponding to the state information of the subsequent L (L is a positive integer) frame of the time division system frame. Therefore, a receiving device can flexibly process the special time slots with the control information in the subsequent frame according to the state information corresponding to the control information indication so as to avoid additional energy loss and processing time delay.

Description

technical field [0001] The present invention relates to the technical field of the third generation universal mobile communication system, in particular to a frame structure with control information indication in a time division system, a method for setting the control information indication in the frame structure, and processing the frame structure at the receiving end Methods and Equipment. Background technique [0002] In traditional broadcasting systems, such as analog TV broadcasting, in order to expand coverage, adjacent transmitting stations use different frequencies to avoid mutual interference, and the same frequency must be reused at a certain distance, which is called Multi-Frequency Network rk, M FN) way. In this way, one signal needs to occupy several times the frequency bandwidth, consuming precious spectrum resources. [0003] With the increasing shortage of spectrum resources and the development of signal processing technology, the networking method of sing...
