Multi-mode base station and method for data transmission

A multi-mode base station, comprising:

• one or more radio equipments (REs) each having a first port and a second port;
• a first radio equipment controller (REC) supporting a first radio access technology;
• and
• a second REC supporting a second radio access technology;
• wherein the first REC is configured to send first downlink data corresponding to the first radio access technology to the RE;
• wherein the RE is configured to:
• receive, through a first port of the RE, the first downlink data from the first REC,
• obtain, from the received first downlink data, data belonging to the RE,
• combine first uplink data corresponding to the second radio access technology with the received first downlink data from the first REC to form first combination data, and
• send the first combination data through a second port of the RE;
• and
• wherein the second REC is configured to receive the first combination data from the RE, and to obtain the first uplink data corresponding to the second group radio access technology from the received first combination data;
• and
• wherein the first REC is further configured to:
• determine, according to radio access technology information received from a link, that the first radio access technology supported by the first REC is different from the second radio access technology supported by the second REC,
• determine, according to a hop number received from the link, that a link mode of the link is a bidirectional link mode, and
• send Layer 1 (L1) information to the RE, wherein the L1 information comprises indication information indicating the bidirectional link mode.

A method of data transmission, comprising:

• sending first downlink data corresponding to a first radio access technology from a first radio equipment controller (REC) supporting the first radio access technology of a base station to a radio equipment (RE) of the base station;
• receiving, by the RE, the downlink data sent from the first REC through a first port of the RE;
• obtaining, by the RE, data belonging to the RE from the received first downlink data;
• combining, by the RE, the first downlink data received from the first REC with first uplink data corresponding to a second radio access technology with to form first combination data;
• sending, by the RE, the first combination data through a second port of the RE;
• receiving, by a second REC supporting the second radio access technology of the base station, the first combination data from the RE;
• obtaining, by the second REC, the first uplink data corresponding to the second group radio access technology from the received first combination data;
• determining, by the first REC according to a slot ID received from a link, that the first radio access technology supported by the first REC is different from the second radio access technology supported by the second REC;
• determining, by the first REC, that a link mode of the link is a bidirectional link mode according to a hop number received from the link, and
• transmitting, by the first REC, layer 1 (L1) information to the RE, the L1 information including indication information indicating the bidirectional link mode.

A method of data transmission, comprising:

• sending first downlink data corresponding to a first radio access technology from a first radio equipment controller (REC) supporting the first radio access technology of a base station to a radio equipment (RE) of the base station;
• receiving, by the RE, the downlink data sent from the first REC through a first port of the RE;
• obtaining, by the RE, data belonging to the RE from the received first downlink data;
• combining, by the RE, the first downlink data received from the first REC with first uplink data corresponding to a second radio access technology with to form first combination data;
• sending, by the RE, the first combination data through a second port of the RE;
• receiving, by a second REC supporting the second radio access technology of the base station, the first combination data from the RE;
• obtaining, by the second REC, the first uplink data corresponding to the second group radio access technology from the received first combination data;
• determining, by the first REC, according to radio access technology information received from a link, that the first radio access technology supported by the first REC is different from the second radio access technology supported by the second REC,
• determining, by the first REC, according to a hop number received from the link, that a link mode of the link is a bidirectional link mode, and
• sending, by the first REC, Layer 1 (L1) information to the RE, the L1 Layer information including indication information about the bidirectional link mode.
