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 wireless data transmission includes a base station having six antennas and at least one user equipment. The base station forms at least one layer of data stream including modulated symbols, precodes the at least one layer of data stream via multiplication with consecutive first and second precoding matrices and transmit the precoded data stream to the at least one user equipment via the six antennas. The first precoding matrix W1 is a block diagonal matrix formed by two identical 3 by Nb matrices, where Nb is the number of distinct Discrete Fourier Transform vectors. The second precoding matrix W2 introduces a phase shift between the two 3 by Nb matrices and selects a column subset from the first precoding matrix.

摘要： A method for mapping data in a wireless communication system. The method includes generating a precoding matrix for multi-antenna transmission based on a precoding matrix indicator (PMI) feedback from at least one remote receiver where the PMI indicates a choice of precoding matrix derived from a matrix multiplication of two matrices from a first code book and a second codebook. The method further includes precoding one or more layers of a data stream with the precoding matrix and transmitting the preceded layers of data stream to the remove receiver.

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： 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.
摘要翻译：本发明是一种用于在多个基站和用户设备之间进行坐标多点无线传输的技术。至少一个基站通过物理下行链路共享信道（PDSCH）发送。用户设备不知道多个基站的身份。这可以包括通过来自多个基站的同时数据传输的联合传输。这可以包括一次从一个基站进行数据传输的动态点选择，并且将发射点（TP）从一个子帧改变到另一个子帧。这可以包括协调调度/波束成形（CS / CB），其中一次从一个基站向用户设备发送数据，并且基站进行通信以协调用户调度和波束成形。传输点（TP）可以在子帧内的资源块（RB）对之间变化，而不从多于一个基站发送。传输点（TP）可以以半静态方式改变。
