    摘要: A wireless transmission system included at least one user equipment and a base station. The base station is operable to form a downlink control information block, modulate the downlink control information, precode the modulated downlink control information, and transmit the precoded, modulated downlink control information on at least one demodulation reference signal antenna port to the at least one user equipment. The precoded, modulated downlink control information is mapped to a set of N1 physical resource block pairs in a subframe from an orthogonal frequency division multiplexing symbol T1 to and orthogonal frequency division multiplexing symbol T2.

    摘要: A base station selects a subset of at least one geographically separated antennas for each of the plurality of user equipments. The base station forms at least layer of data stream including modulated symbols, precodes the data stream via multiplication with the NT-by-N precoding matrix where N is the number of said layers and NT is the number of transmit antenna elements and transmits the precoded layers of data stream to the user equipment via the selected geographically separated antennas. The base station signals the subset of the plurality of geographically separated antennas via higher layer Radio Resource Control or via a down link grant mechanism. The base station optionally does not signal the subset of the plurality of geographically separated antennas to the corresponding mobile user equipment.

    摘要: A method of Coordinated Multipoint (CoMP) communication between a base station has a plurality of points with at least one user equipment (UE). At least one UE receives at least one transmission from the base station having the plurality of points. This UE measures downlink channel state information for each of the plurality of points including a rank indicator (RI), a precoding matrix indicator (PMI) and a channel quality indicator (CQI). This UE transmits the downlink channel station information in an uplink feedback channel to the base station.

    摘要: This invention mitigates interference in wireless telephony in heterogeneous networks having a macro base station and a low power base station. This invention attempts to avoid cross carrier scheduling on an anchor carrier and a non-anchor carrier. If cross carrier scheduling is unavoidable, then this invention attempts: (1) semi-statically signalling a CFI value on a cross-scheduled component carrier; (2) semi-statically signalling a channel quality information (CSI) value on a cross-scheduled component carrier setting a Physical Hybrid ARQ Indicator CHannel (PHICH) value to be maximum; or (3) semi-statically signalling a channel quality information (CSI) value on a cross-scheduled component carrier using Physical Control Format Indicator CHannel (PCFICH) power boosting on cross-scheduled component carriers (CC).

    摘要: The primary serving base station transmits PDSCH with zero energy on the inter-cell CRS resource element location. This is called mute PDSCH. Within the first Physical Resource Block (PRB 0), the RE positions in the frequency domain are indexed between 0 and 11. The muted PDSCH RE positions per antenna port are computed using the cell IDs of all CoMP cells other than the cell ID i. The invention defines the Orthogonal Frequency Division Multiplexing (OFDM) symbols in which muting occurs.

    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.
