摘要： Systems and techniques for communication using coordinated multi-point transmission. In one embodiment, an apparatus comprises at least one processor and a memory storing a set of computer instructions, configured. The processor is configured to cause the apparatus to determine a linear phase variation between at least first and second transmissions from first and second transmission points based at least in part on a propagation delay difference between the first and second transmissions, and transmit the phase variation information for at least the first and the second transmissions. An apparatus configured to operate as a transmission point in a network receives linear phase variation information indicating phase variation experienced by at least one user equipment resulting from a propagation delay difference between at least the apparatus and a second apparatus operating as a second transmission point and manages transmission so as to control phase variation resulting from the propagation delay difference.

摘要： A resource allocation for a specific user equipment (UE)is encoded using an encoding scheme that identifies a specific antenna port from among a plurality of antenna ports; and the encoded resource allocation is output to the specific antenna port for transmission to the specific UE. The UE blindly detects its control channel and determines its resource allocation by decoding the control channel using a decoding scheme that identifies a specific antenna port from among the plurality of transmit antenna ports. In various embodiments, the scheme is in scrambling or masking (using an ID of the antenna portor UE); by the order of bits when encoding, port specific mapping constellations, and adding bits that give the port index.
