Embodiment Construction
[0016] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0017] The core idea of the present invention is: for each sector, set a full-coverage carrier dedicated to providing network coverage, and make the full-coverage carriers of adjacent sectors different; The PDCCH channel of the non-full coverage carrier is transmitted with reduced power; the full coverage carrier of each sector is mainly responsible for providing PDCCH resources for the scheduling of UEs at the sector edge, so as to reduce the inter-PDCCH interference at the sector edge and improve the received SNR of the PDCCH channel At the same time, because the power of the PDCCH on the non-full coverage carrier is only reduced, that is, the power of the traffic channel of the non-full coverage carrier is not reduced, it can ensure t...
