Wireless communication with co-operating cells

摘要: In an LTE-based wireless communication system, each channel such as a control PDCCH is transmitted to the UE from one serving cell (the primary or Pcell). At border Pcell suffers increased interference neighbouring cells and typically lower effective transmission rate used increase robustness interference, for both data channel. Also, are given different IDs, which can be basis distinguishing transmissions cells, even if radio frames time-aligned. The invention modifies operation by arranging common mapping of symbols resources in two so that same message (P) part jointly ((a),(b)), avoiding respective reference signals (R). This improve reception at border, without using more resources. would beneficial normal system also Co-operative Multi-Point (CoMP) operation, e.g. joint techniques data.
