    Abstract: The present invention provides a method and system for enabling machine type communication in a long term evolution (LTE) network environment. In one embodiment, a Physical (PHY) layer of a LTE protocol stack maps data bits in resource elements of a logical channel to resource elements of a physical channel. The PHY layer identifies the data bits intended for legacy devices but mapped to a first set of resource elements of machine type communication (MTC) devices and the data bits intended for the MTC device but mapped to the second set of resource elements of the legacy devices. Accordingly, the PHY layer remaps the data bits intended for the legacy devices to the second set of resource elements and the data bits intended for the MTC devices to the first set of resource elements prior to transmission.

    Abstract translation: 本发明提供了一种用于在长期演进（LTE）网络环境中实现机器类型通信的方法和系统。 在一个实施例中，LTE协议栈的物理（PHY）层将逻辑信道的资源元素中的数据位映射到物理信道的资源元素。 PHY层标识用于传统设备的数据位，但映射到机器类型通信（MTC）设备的第一组资源元素，以及用于MTC设备但映射到传统设备的第二组资源元素的数据位 。 因此，PHY层在传输之前将用于传统设备的数据位重新映射到第二组资源元素和用于MTC设备的数据位给第一组资源元素。

    Abstract: The present disclosure provides a method of selecting a plurality of sets of beam pairs in a wireless communication system. The method includes estimating, by a receiver, channels associated with a plurality of transmit ports for each receive port of a plurality of receive ports; and determining, by the receiver, the plurality of sets of the beam pairs including transmit beam and receive beam using: an average power level at each receive port for at least one transmit port based on the estimated channel associated between the beam pairs, a set of first power matrices, wherein each first power matrix, from the set of first power matrices, comprises at least one transmit port, beam ID pairs including transmit beam ID and receive beam ID associated with each receive port, wherein the set of first power matrices is formed based on the average power level at each of the receive port, and a second capacity matrix formed based on capacity maximization obtained from the set of first power matrices, wherein the plurality of sets of the beam pairs associated with each of the transmit port and receive port is selected from the second capacity matrix.
