Embodiment Construction

[0053] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0054] figure 1 It is a schematic diagram of an embodiment of the information sending method of the present invention. Such as figure 1 As shown, the information sending method of this embodiment is as follows:

[0055] Step 101, in the centralized baseband control unit, the first data scheduling unit receives data and controls the N original information sent by the transmission function unit, wherein the centralized baseband control unit communicates with N remote processing units, and the N original information is connected with N There is a one-to-one correspondence between the remote processing units, and N is a positive integer greater than 1.

[0056] Step 102, the first data scheduling unit obtains N physical layer control information corresponding to the N remote processing units one-to-...

Abstract

The invention discloses a method and a system for transmitting information and a method and a system for receiving information. According to the method for transmitting the information, a centralized base band control unit transmits raw information, physical layer control information and remote processing unit configuration information to all remote processing units, and base band processing is conducted on remote processing units. According to the method for receiving the information, all remote processing units conduct base band processing on the received information to obtain the raw information and transmit the raw information and corresponding feedback information to the centralized base band control unit. Thus, the information transmission quantity between the centralized base band control unit and all remote processing units can be reduced, and the relay requirements between the centralized base band control unit and all remote processing units can be reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to an information sending method and its system, an information receiving method and its system. Background technique [0002] With the continuous increase of mobile users using data services, the requirements for mobile network data capabilities are getting higher and higher. The Long Term Evolution (LTE for short) system is based on Orthogonal Frequency Division Multiplexing (OFDM for short) and Multiple Input Multiple Output (MIMO for short), providing lower transmission delay and more The mobile communication system with high user transmission rate has won the support of most operators and equipment manufacturers in the world. Specifically, in terms of network deployment, in order to improve the performance of cell-edge users and meet the requirements of cell-edge spectrum efficiency, LTE introduces Coordinated Multi-Point (Coordinated Multi-Point, CoMP) technology into its evolved sy...
