Co-frequency networking method and apparatus based on cluster service

A base station for co-frequency networking based on a trunking service, comprising a processor and a plurality of transmission trunking ports, wherein:

• each of the transmission trunking ports is configured with a trunking-specific reference signal;
• and
• the processor is configured to:
• acquire a multi-layer data flow generated through a layer mapping process,
• pre-code the multi-layer data flow with a preset multi-port pre-coding method to obtain encoded data of each of the transmission trunking ports, wherein the multi-port pre-coding method matches with the preset plurality of transmission trunking ports,
• perform resource mapping on the encoded data and the trunking-specific reference signal of each of the transmission trunking ports to obtain transmission data of the transmission trunking port, and
• transmit the transmission data of each of the transmission trunking ports to the transmission trunking port;
• and
• each of the transmission trunking ports is configured to:
• receive the transmission data transmitted by the processor, and
• transmit the received transmission data to reception trunking ports which match with the transmission trunking port using the transmission trunking port, wherein the reception trunking ports which match with the transmission trunking port are provided on a plurality of user equipments UEs in a same group in a trunking system, and are configured with the same trunking-specific reference signal as the transmission trunking port.

A terminal for co-frequency networking based on a trunking service, comprising a plurality of reception trunking ports and a processor, wherein:

• each of the reception trunking ports is configured with a trunking-specific reference signal, and is configured to:
• receive the same transmission data transmitted by transmission trunking ports of a plurality of base stations in a trunking system which match with the reception trunking port, and
• transmit the received transmission data to the processor, wherein the transmission trunking ports which match with the reception trunking port are configured with the same trunking-specific reference signal as the reception trunking port;
• and
• the processor is configured to:
• receive the transmission data transmitted by each of the reception trunking ports,
• demodulate the transmission data received by each of the reception trunking ports using the trunking-specific reference signal configured for the trunking port, to obtain encoded data of the reception trunking port, and
• decode the encoded data of each of the reception trunking ports with a decoding method corresponding to a multi-port pre-coding method to obtain a multi-layer data flow.
