Abstract

A system, transceiver, computer programming product, and method of regulating transmission of a packet from a transceiver are provided. The method includes measuring, by the transceiver, the electronic magnetic radiation (EMR) for an allocated uplink (UL) grant at a transmission time interval (TTI), detecting, by the transceiver, if the measured EMR exceeds an EMR threshold; and regulating, at the transceiver, a transmission of the packet to reduce the EMR.

measuring, by the transceiver, electronic magnetic radiation (EMR) for an allocated uplink (UL) grant at a transmission time interval (TTI);

detecting, by the transceiver, if the measured EMR exceeds an EMR threshold; and

regulating, at the transceiver, a transmission of the packet to reduce the EMR,

wherein regulating, at the transceiver, the transmission of the packet to reduce the EMR comprises;

quantizing the measured EMR into a plurality of EMR indexes;

determining a bundle size corresponding to at least one EMR index of the plurality of EMR indexes, wherein the bundle size is shared in association with an activation time to trigger a TTI bundling; and

adjusting an applied power based on the bundle size for the transmission of the packet.

2. The method of claim 1, wherein regulating, at the transceiver, the transmission of the packet to reduce the EMR further comprises muting the transmission of the packet for an allocated UL grant for at least one TTI based on the measured EMR.

3. The method of claim 1, wherein regulating, at the transceiver, the transmission of the packet to reduce the EMR further comprises:

adjusting an applied power based on the measured EMR; and

transmitting the packet based on the adjusted applied power.

4. The method of claim 3, wherein adjusting the applied power based on the measured EMR comprises:

quantizing the measured EMR into a plurality of EMR indexes; and

adjusting the applied power corresponding to the at least one EMR index from the plurality of EMR indexes for transmitting the packet.

5. The method of claim 1, wherein regulating, at the transceiver, the transmission of the packet to reduce the EMR further comprises:

adjusting a spatial direction of at least one antenna based on the at least one EMR index from the plurality of EMR indexes; and

transmitting the packet based on the adjusted spatial direction of the at least one antenna.

6. The method of claim 5, wherein the spatial direction of the at least one antenna is adjusted using a phase shifter, wherein each of the at least one antenna transmits a same waveform with a phase difference.

7. The method of claim 5, wherein the spatial direction of the at least one antenna is adjusted for the EMR index based on a proximity level.

8. The method of claim 5, wherein adjusting the spatial direction of the at least one antenna based on the at least one EMR index from the plurality of EMR indexes comprises:

determining a lower eigen direction from a plurality of eigen directions for the at least one EMR index from the plurality of EMR indexes; and

adjusting a power allocation to the lower eigen direction.

9. The method of claim 1, wherein regulating, at the transceiver, the transmission of the packet to reduce the EMR further comprises:

measuring, by the transceiver, a power head room (PHR) based on the at least one EMR index from the plurality of EMR indexes; and

broadcasting, by the transceiver, a PHR measurement report.
