INTERFACE BETWEEN LOW POWER NODE AND MACRO CELL TO ENABLE DECOUPLED UPLINK AND DOWNLINK COMMUNICATION

摘要

Certain aspects provide a method for wireless communications by low cost, low cost, low cost devices such as machine type communications (MTC) devices. A method for wireless communications by a wireless node is provided. The method generally includes receiving signaling indicative of a random access channel (RACH) configuration for a wireless device from a cell's base station, detecting a wireless device performing a RACH procedure based on the RACH configuration, Receiving a signaling indicating that the wireless node has been selected to serve the wireless device for uplink communications with the base station of the cell, receiving the transmitted uplink data from the wireless device, And forwarding the uplink data to the base station of the cell.
