[0040] Embodiment 1: Control channel design with fixed SCH position

[0041] In the first embodiment according to the present invention, the position of the SCH is fixed, and the control channel of this mode has the above reference figure 2 In addition to the characteristics of the subframe-based control channel described, it also has the following characteristics:

[0042] In the radio resources included in the frame, the position of the SCH is fixed, and is indicated by the frame header or other common broadcast messages. The position of the subframe MAP in the scheduling area controlled by the SCH is dynamic, and the position, length, modulation and coding mode and transmission mode of the MAP are indicated by the SCH.

[0043] When the position of the SCH is fixed, the terminal judges which subframes need to receive the subframe MAP according to the indication information contained in the SCH at the fixed position, and does not need to monitor all the subframes, thereby ...

[0048] The second embodiment: control channel design with dynamic SCH position

[0049] In the second embodiment according to the present invention, the position of the SCH is not fixed, and the control channel of this mode needs to have the above reference figure 2 In addition to the characteristics of the subframe-based control channel described, it also has the following characteristics:

[0050] In the radio resources included in the frame, the position of the SCH is not fixed, but dynamic, that is, its position is determined according to the scheduling needs of the base station. Compared with the first embodiment, the position of the subframe MAP in the scheduling area controlled by the SCH is still dynamic, and the position, length and modulation and coding mode of the MAP are still indicated by the SCH.

[0051] When the position of the SCH is dynamic, the terminal needs to monitor each position where the SCH may appear, and then judge whether there is an SCH, and det...

[0058] In the third embodiment according to the present invention, the position of the SCH is not fixed, and the control channel of this mode needs to have the above reference figure 2 In addition to the characteristics of the subframe-based control channel described, it also has the following characteristics:

[0059] In the wireless resources contained in the frame, the position of the SCH is not fixed, but dynamic, that is, its position is determined according to the scheduling needs of the base station, and the SCH carries the information of the next SCH, including whether it exists and the position information etc., that is, the presence or absence of the next SCH and its position are specified by the previous SCH, finally forming a chained SCH structure. The location of the subframe MAP in the scheduling area controlled by the SCH is still dynamic, and the location, length, and modulation and coding mode of the MAP are still indicated by the SCH.

Abstract

The invention discloses a control channel design method, which comprises: setting a dispatching-based control head in a subframe of a frame according to the dispatching of a base station, wherein the dispatching-based control head controls one subframe or one subframe area consisting of a plurality of subframes of the dispatching of the base station and carries control information; and according to the control information of the dispatching-based control head, setting a mapping symbol in the subframe or the subframe area controlled by the dispatching-based control head, wherein the mapping symbol is used for indicating the resource allocation situations of one or more subframes.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for designing a control channel in a wireless communication system using a base station to implement wireless resource scheduling. Background technique [0002] In a wireless communication system, a base station refers to a device that provides services for a terminal. The base station communicates with the terminal through uplink and downlink. The downlink refers to the direction from the base station to the terminal, and the uplink refers to the direction from the terminal to the base station. Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. [0003] In a wireless communication system that uses a base station to implement wireless resource scheduling control, the scheduling and allocation of system wireless resources is completed by the bas...
