Abstract

The invention provides a method and device for transmitting non-I (in-phase) / Q (quadrature phase) data through a common public radio interface (CPRI), and belongs to the technical field of communications. The device comprises a packaging module and a transmission module. The method comprises the following steps: when the CPRI is positioned before downlink modulation or after uplink demodulation, adding a packet header to the data transmitted on the CPRI and then packaging the data into an information packet, wherein, the header comprises at least one or more than one field as follows: an destination address field, a source address field, a packet type field, a start-of-packet (SOP) / end-of-packet (EOP) mark field, a data length field and a sequence number field; mapping the information packet into one or more than one information packet container; bearing the information packet container in a superframe; and transmitting the superframe through the CPRI. By utilizing the method and the device, the non-I / Q data can be borne in a CPRI frame and transmitted through the CPRI.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a non-I (In-Phase, in-phase component) / Q (Quadrature Phase, quadrature component) data transmission method and device of a common public wireless interface. Background technique

[0002] The CPRI (Common Public Radio Interface, Common Public Radio Interface) protocol provides a public protocol for the interface between the wireless device controller and the wireless device. The wireless service data transmitted on the existing CPRI protocol is based on I / Q digital baseband data, so the CPRI interface division position of the wireless communication system is before uplink demodulation and after downlink modulation. That is, REC (Radio Equipment Control, wireless equipment controller) completes data baseband processing, and RE (Radio Equipment, wireless equipment) completes analog wireless frequency domain functions.

[0003] In the process of realizing the present ...
