Problems solved by technology

[0004] The first two fusion solutions are mainly integrated on the network side. The mobile phone needs two sets of independent wireless transceiver equipment, which brings challenges to the cost and interference design of the mobile phone, and increases the manufacturing cost and design complexity.

Embodiment Construction

[0065] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0066] The method of integrating the TD-SCDMA and WIMAX systems on the air interface of the present invention can be divided into a tight fusion method and a loose fusion method. The system integration of these two methods will be described separately below.

[0067] The first is the loose fusion approach. figure 1 It shows the flow of an embodiment of the transmitting / receiving method of the base station in which TD-SCDMA and WIMAX are integrated in the loose integration mode. See figure 1 , the following is a detailed description of each step in the process flow of the method.

[0068] Step S10: Send the TS0 time slot and the downlink pilot time slot DwPTS of the LCR TDD frame (low chip rate time division duplex frame). In the 3GPP agreement, LCR TDD is another name for TD-SCDMA.

[0069] Step S12: Receive uplink pilot time slot UpPTS and possibl...

Abstract

The invention discloses a method and a device for sending and receiving a base station in the integration manner. A TD-SCDMA system and a WIMAX system are integrated over an air interface, the complementarities of the two systems are fully used, a the cost of a mobile phone wireless transceiver is reduced and the design thereof is simplified. The technical scheme is as follows: the wireless frames of the TD-SCDMA AND WINMAX are combined into a compound frame in the time division manner, so that the invention can occupy the same frequency range resource and can be continuous in time. Therefore, one radio transceiver can have access to both TD-SCDMA and WIMAX systems. And the invention is applicable in the radio communications field.

Description

technical field [0001] The present invention relates to a fusion technology of different mobile communication standards, in particular to the TD-SCDMA standard in the third generation mobile communication system IMT-2000 and IEEE's 802.16d / e broadband fixed and mobile wireless access standard (also called WIMAX) on the air interface convergence. Background technique [0002] TD-SCDMA is the third-generation mobile communication system air interface standard proposed by China. It has entered IMT-2000 and has made great progress in industrialization. It is expected to occupy an important position in China's 3G communication. TD-SCDMA technology has many advantages: high spectrum utilization rate, the use of smart antenna, software radio and other technologies can improve system capacity, suitable for asymmetrical business transmission. However, since TD-SCDMA evolved from the traditional telecommunication technology, the service it mainly supports is still the voice service o...
