On transparency of CoMP
摘要:
This invention is a technique for coordinate multi-point wireless transmission between plural base stations and user equipment. At least one base station transmits via a Physical Downlink Shared CHannel (PDSCH). The user equipment does not know the identity of the plural base stations. This could include joint transmission by simultaneous data transmission from multiple base stations. This could include dynamic point selection by data transmission from one base station at a time and changing the transmitting point (TP) from one subframe to another subframe. This could include coordinated scheduling/beamforming (CS/CB) where data is transmitted to the user equipment from one base station at a time and the base stations communicate to coordinate user scheduling and beamforming. The transmission point (TP) could vary over Resource Block (RB) pairs within a subframe while never transmitting from more than one base station. The transmission point (TP) could change in a semi-static fashion.
