Embodiment 1
[0091] The method for obtaining the inter-beam interference relationship described in this preferred embodiment is suitable for obtaining the in-band and / or out-of-band interference relationship between the transmitting beam of the neighboring cell and the receiving beam of the own cell in the communication system of the shaped beam, such as Figure 5 As shown, the following steps S502 to S508 are included.
[0092] Step S502, controlling the direction of the main transmit beam of the shaped beam of the adjacent cell, so that the main transmit beam points to different directions in different time intervals to cover different areas in the adjacent cell, and the main transmit beam has one beam in one time interval In the dwell state, at least two beam dwell states form a beam dwell state sequence.
[0093] Step S504, corresponding to the beam dwell state, the array antenna of the local cell receives the transmission signal from the shaped beam and sends the received transmission...
Embodiment 2
[0137] The communication method based on the inter-beam interference relationship described in this preferred embodiment is suitable for suppressing the same-frequency and / or adjacent-frequency interference between beams between cells using shaped beams, and specifically includes: obtaining the main The beam dwell state sequence information of the transmit beam uses the interference relationship between the shaped beam of the local cell and the shaped beam of the adjacent cell to determine whether the main receiving beam pointing sequence corresponding to the beam dwell state in the beam dwell state sequence exists The direction of the weakly interfered main receiving beam, if there is a weakly interfered main receiving beam pointing, then the cell in the weakly interfered The main receiving beam points upward to receive the signal sent by the terminal in the cell.
[0138] The specific method for obtaining the beam dwell state sequence information of the main transmit beam of...
Embodiment 3
[0148] The system for obtaining the inter-beam interference relationship described in this preferred embodiment is suitable for obtaining the in-band and / or out-of-band interference relationship between the transmitting beam of the neighboring cell and the receiving beam of the own cell in the communication system of the shaped beam, such as Figure 7 shown, including:
[0149] The adjacent cell shaped beam transmitting unit 702 includes a group of antenna units and a group of transmission channels corresponding to the antenna units for transmitting the shaped beam;
[0150] The beamforming receiving unit 701 of this cell includes a group of antenna units and a group of receiving channels corresponding to the antenna units, which are used to receive signals transmitted by the shaped beams of neighboring cells in the form of shaped beams;
[0151] The adjacent cell shaped beam transmission control unit 707 is used to control the beam dwell state of the adjacent cell shaped beam...
