Abstract: Various communication systems may benefit from managing signal interference. For example, certain wireless communication systems may benefit from a dynamic time division duplex system involving slot allocation. A method includes allocating, by an access point, in a time division duplex frame a plurality of radio resource slots, each one of the plurality of radio resource slots being allocated for a downlink or an uplink transmission, and determining that the allocation of the downlink or uplink transmission should be changed. The method also includes applying a permutation pattern to re-allocate at least one of the plurality of radio resource slots for the downlink or uplink transmission.

Abstract: A method and apparatus can be configured to receive a first scheduling request. The first scheduling request corresponds to a request for a first access point to process data. The method can also include transmitting a second scheduling request. The second scheduling request corresponds to a request to transmit data to a second access point. The transmitting the second scheduling request comprises transmitting the second scheduling request before the data is processed at the first access point.

Abstract: The exemplary embodiments of the invention provide at least a method and an apparatus to determine a beacon signal for a network node, where the network node is configured to connect with a cluster of access points in a wireless communication network, and where the beacon signal identifies the cluster; and send the beacon signal towards the wireless communication network. Further, the exemplary embodiments of the invention provide at least a method and an apparatus to determine a dominant access point of a cluster of access points based on signaling from at least one access point associated with the cluster of access points; and in response to the determining, direct communications towards the dominant access point of the cluster of access points.

Abstract: A technique of reducing interference at a wireless node includes: determining a location of a base station relative to a wireless node, determining, based at least on the location of the base station relative to the wireless node, a beam-reduction region that includes one or more interfering transmit beams of the base station within the beam-reduction region, and causing the base station to decrease a transmit power for the one or more interfering transmit beams within the beam-reduction region.

Abstract: A group of data symbols for a current block of data symbols in multiple blocks received over a communication channel is equalized, based on a pilot block, to generate a group of equalized symbols. The group of equalized symbols is de-rotated as a function of a current phase estimate to determine initial de-rotated equalized symbols. The phase estimate is an estimate of phase caused by noise for blocks previous to the current block. Additionally, a phase metric is calculated from real and imaginary parts of the initial de-rotated equalized symbols, wherein the phase metric estimates phase caused by noise for the current block. The current phase estimate is updated with the phase metric. The initial de-rotated equalized symbols are de-rotated by the phase metric to determine final equalized and de-rotated symbol estimates. The final equalized and de-rotated symbol estimates are output. Apparatus, methods, and computer program products are disclosed.

Abstract: A method and apparatus may determine a plurality of access points. The plurality of access points belong to a cluster set of a user device. The method may also include allocating a plurality of uplink access channels to the plurality of access points. The plurality of uplink access channels may include uplink polling channels. The plurality of uplink access channels are allocated such that the plurality of access channels are staggered in time within a frame structure used by the plurality of access points and the user device.

Abstract translation: 基于导频块，在通过通信信道接收的多个块中的当前数据符号块的一组数据符号被均衡，以生成一组均衡的符号。 作为当前相位估计的函数，均衡符号组被去旋转以确定初始去旋转均衡符号。 相位估计是对当前块之前的块的噪声引起的相位的估计。 另外，根据初始去旋转均衡符号的实部和虚部来计算相位量度，其中相位度量估计由当前块的噪声引起的相位。 当前相位估计用相位量度更新。 初始去旋转的均衡符号通过相位度量被去旋转以确定最终的均衡和去旋转符号估计。 输出最终均衡和去旋转的符号估计。 公开了装置，方法和计算机程序产品。
