MAXIMUM PATHLOSS MEASUREMENT FOR BROADCAST COMMUNICATION

摘要

Methods, systems, and devices are described for determining pathloss. A transmitter may send a reference signal to receivers associated with broadcast transmissions. The receivers participating in the broadcast transmissions that receive the reference signal at a pathloss greater than a predetermined pathloss value may send a response to the reference signal. Receivers that receive the reference signal at a pathloss less than the predetermined pathloss value may not send a response. The pathloss may be determined based on whether a response is received. The transmitter may then transmit signals for the broadcast transmission at a power level determined based on the pathloss value.
