Abstract: A base stations (BS) are configured to perform a coordinated transmission to at least one user equipment (UE). The BS includes a plurality of antenna configured to communicate with the UE. The BS also includes processing circuitry coupled to the plurality of antennas and configured to transmit physical downlink control channel (PDCCH) to the at least one user equipment. The UE includes a plurality of antennas configured to communicate with the BS. The UE also includes a processing circuitry coupled to the plurality of antennas and configured to receive PDCCH from the BS. The PDCCH is included in one or more transmit (Tx) beams. A Tx beam is defined by the cell specific reference signal (CRS) transmitted through the Tx beam. A Tx beam is configured to carry a beam identifier, and the PDCCH is configured to include resource allocation information for the user equipment.

Abstract translation: 基站（BS）被配置为对至少一个用户设备（UE）执行协调传输。 BS包括被配置为与UE进行通信的多个天线。 BS还包括耦合到多个天线并被配置为向至少一个用户设备发送物理下行链路控制信道（PDCCH）的处理电路。 UE包括被配置为与BS进行通信的多个天线。 UE还包括耦合到多个天线并被配置为从BS接收PDCCH的处理电路。 PDCCH被包括在一个或多个发射（Tx）波束中。 Tx波束由通过Tx波束发射的小区特定参考信号（CRS）定义。 Tx波束被配置为携带波束标识符，并且PDCCH被配置为包括用于用户设备的资源分配信息。
