Embodiment Construction

[0034] Please refer to FIG. 2 , which is a realization block diagram of a method for realizing the transmission and reception control of the TD-SCDMA system under different conditions of the present invention. As shown in the figure: each control action is composed of the above basic control operations and their trigger time. In each period (such as a frame) all control actions are arranged into a list according to the order of trigger time. At the beginning of each cycle, the control action execution device obtains the control action information from the control action list, and then generates a corresponding RF control signal according to the information. The list of control actions is generated by a control action generator, usually a program running on a microprocessor. This method introduces how to use the basic control operations defined above to generate corresponding control action sequences, thereby generating the required TD-SCDMA RF control signals.

Abstract

The present invention relates to the receiving and transmitting control technology in TD-SCDMA mobile communication system, and is especially the receiving and transmitting control method in TD-SCDMA mobile communication system in different conditions. Each of the control operations consists of basic control operation and triggering time, and there are seven kinds of basic control operation, including RFPLL relevant control operation. All the control actions in each period are listed according to the triggering time order, and in the beginning of each period, the control executing device takes the relevant control action information from the control action list and then generates corresponding RF control signal, with the control action list being generated with a control action generator. The present invention eliminates the time conflict and makes the control simple in TD-SCDMA mobile communication system.

Description

technical field [0001] The invention relates to the sending and receiving control technology in the TD-SCDMA mobile communication system, in particular to a method for realizing the sending and receiving control in different situations of the TD-SCDMA system. Background technique [0002] A communication system requires correct transceiver control to transmit and receive signals. For time-division systems, it is very important to generate the correct control signal at the exact moment. Usually the basic sending and receiving unit of a time division system is a time slot (slot). Taking GSM as an example, the basic sending and receiving operations include receiving a time slot and sending a time slot. For a multi-slot transceiver communication system, such as GPRS, there are also operations such as receiving two time slots, sending two time slots, receiving three time slots, and so on. For each receiving or sending operation, it can be subdivided into operations related to ...
