Communication signal multiplexing method, radio communication system, and radio equipment controller

摘要

The present invention discloses a communication signal multiplexing method, a radio communication system, and a radio equipment controller (REC). Taking the common public radio interface (CPRI) standard as an example, by carrying multiple CPRI links on limited physical links (CPRI-MUX), generally one high-speed physical link, physical bandwidth is used more efficiently and the number of interconnected interfaces and the system cost are reduced without compromising with the CPRI standard is maintained. When the bandwidth provided by the high-speed physical link is insufficient, more physical links can be adopted.

主权项

1. A communication signal multiplexing method, applicable to a radio communication system, comprising:
receiving, by a second radio equipment controller (REC), first multiplexed data, the data sent by a first radio equipment controller (REC) to a first multi-mode radio equipment (RE) and to a second multi-mode RE; demultiplexing the first multiplexed data to obtain data sent by the first REC to the first multi-mode RE and to obtain data sent by the first REC to the second multi-mode RE; multiplexing the data sent by the first REC to the first multi-mode RE and data sent by the second REC to the first multi-mode RE, to obtain second data; multiplexing the data sent by the first REC to the second multi-mode RE and data sent by the second REC to the second multi-mode RE, to obtain third data; sending the second data to the first multi-mode RE; and sending the third data to the second multi-mode RE; wherein: the first multiplexed data is obtained by multiplexing the data sent by the first REC to the first multi-mode RE and the data sent by the first REC to the second multi-mode RE on at least one physical link and by including link multiplexing information indicative of a frame of the first multiplexed data being a multiplexed frame, number of ports connecting RECs and REs, and a length and a start position of control information of the ports or a length and a start position of service information of the ports and the second REC receives the first multiplex data from the first REC through the at least one physical link.
