    • The inventive methods and apparatus disclosed herein allocate and assign uplink reference signals to cells (104, 106) within a cell cluster (100, 302, 402, 502) based on the type of cell. According to an embodiment, uplink reference signals are allocated within a cell cluster (100, 102, 302, 402, 502) by partitioning a set of uplink reference signals allocated to the cell cluster (100, 102, 302, 402, 502) into mutually exclusive subsets of uplink reference signals. One of the subsets is allocated to each of the border cells (104) and the entire set of uplink reference signals is allocated to the interior cells (106). Accordingly, more uplink reference signals are available for assignment to mobile devices (310, 410, 510) served by the interior cells (106) than by the border cells (104). In one embodiment, uplink reference signals are statically or semi-dynamically assigned to mobile devices (310, 410, 510) served within the border cells (104) and dynamically assigned to mobile devices (310, 410, 510) served within the interior cells (106).
    • 本文公开的本发明的方法和装置基于小区的类型来分配和分配上行链路参考信号到小区簇(100,302,402,502)内的小区(104,106)。 根据一个实施例,通过将分配给小区簇(100,102,302,402,502)的一组上行链路参考信号划分成小区群集(100,102,302,402,502),将上行链路参考信号分配到 上行链路参考信号的互斥子集。 其中一个子集被分配给每个边界单元(104),并且整个上行链路参考信号集合被分配给内部单元(106)。 因此,更多的上行链路参考信号可用于分配给由内部小区(106)服务的移动设备比由边界小区(104)提供服务的移动设备(310,410,510)。 在一个实施例中,上行链路参考信号被静态或半动态地分配给在边界小区(104)内服务的移动设备(310,410,510),并且动态地分配给在内部小区内服务的移动设备(310,410,510) (106)。

    • Multipoint wireless communications are coordinated in cells with radiation that is emanated from antennas in an inward direction. In an example embodiment, an apparatus includes a first antenna, a second antenna, a third antenna and a controller. The first antenna emanates radiation from a first location in an inwardly direction for a cell. The second antenna emanates radiation from a second location in an inwardly direction for the cell. The third antenna emanates radiation from a third location in an inwardly direction for the cell. The controller coordinates the emanation of the radiation via the first, second, and third antennas so as to reduce intra-cell interference for remote terminals located within the cell. The coordination may be effected in accordance with one or more coordinated multi-point (transmission/reception) (CoMP) techniques. Different numbers of sub-cells and antennas per cell and different CoMP cell organizations may be implemented.

    • Network-wide inter-cell interference is reduced by aggregating cells (herein, sub-cells) into Coordinated MultiPoint (CoMP) cells, each having a controller. The CoMP cells are divided into sets, similar to a frequency reuse plan. Scheduling information regarding transmissions scheduled to and from UEs in one set of CoMP cells is transmitted to controllers in sets of neighboring CoMP cells, in advance of the transmissions. Controllers in the receiving sets of CoMP cells schedule transmission to minimize both inter-sub-cell interference and interference with the set of CoMP cells that transmitted the scheduling information, and assuming no interference from other CoMP cells. They then transmit scheduling information to subsequent set(s) of CoMP cells. The order of scheduling information transmission between sets of CoMP cells may be rotated for fairness. The scheduling information may range from bare threshold data indicating at least one transmission, to detailed information such as estimated path gains to each UE.
    • 通过将小区(这里是子小区)聚合到协调多点(CoMP)小区中,每个小区具有控制器来减少网络范围的小区间干扰。 CoMP单元被分为几组,类似于频率复用计划。 关于在一组CoMP小区中调度到UE的传输的调度信息在传输之前被传送到相邻CoMP小区的集合中的控制器。 CoMP小区的接收组中的控制器调度传输以最小化发送调度信息的CoMP小区集合的子小区间干扰和干扰,并且不考虑来自其他CoMP小区的干扰。 然后,它们将调度信息发送到后续的CoMP单元组。 可以旋转CoMP单元组之间的调度信息传输的顺序以获得公平性。 调度信息可以从指示至少一个传输的裸阈值数据到诸如到每个UE的估计路径增益的详细信息。

    • A system and method to perform Full Duplex (FD) Space Division Duplex (SDD) communication using a Self-Interference Cancelling (SIC) precoder that applies different antenna phase shifts and amplitude scales to the transmitted signals to force them to be in the null space of the selected receive antennas. Thus, a wireless communication unit can place nulls at each of its receive antennas digitally at baseband for one or more frequency bands. The SIC precoder may be computed based on the self-interference channel from the transmit chain(s) to the receive chain(s). Different SIC precoders may be adaptively selected and stored digitally for different frequency bands. Subsequent single or multi-user precoder can be applied in concatenation with the SIC precoder to transmit signals to one or more users while receiving signals from one or more users simultaneously over the same frequency band.

    • A signature sequence is employed in a wireless transmission over a channel and is detected by a receiving station. The signature sequence is selected from a subset of sequences chosen from a set of sequences formed by delay-Doppler shifts of a base sequence. Use of the subset of sequences simplifies detection of the signature sequence by, e.g., facilitating use of a simpler detector structure. A subset of N2 sequences of the specially-constructed delay-Doppler shifted sequence set is selected to facilitate more efficient computation of the detection metric. A simplified detector employs algebraic techniques (such as Discrete Fourier 'Transform (DFT)) that exploit prudent sequence assignment strategy. As an advantageous variation, for a particular class of base sequences that can be represented by segments of equal-length sinusoids, even greater complexity reduction can be achieved by segmenting the delay-Doppler correlation accordingly and reusing past outcome in subsequent overlapping segments.
