Abstract
The present disclosure describes techniques and systems for user device-initiated downlink power requests. Techniques for user device-initiated downlink power requests may include a user device using a signal quality of a downlink communication to optimize transmission power of the downlink communication. Based on this determination, the user device transmits, to a base station, a request to change a transmission power level for a future downlink communication. The base station can receive the request and, based on the request, adjust the transmission power level for a future communication.
Claims20
A method performed by a user device for user device-initiated downlink power requests in a wireless communication network, the method comprising:
- receiving, via a wireless connection with a base station, a downlink communication over a channel of the wireless connection, the downlink communication transmitted at a first transmission power level;
- determining a signal quality of the received downlink communication over the channel of the wireless connection;
- determining, based on the signal quality, a second transmission power level for a future downlink communication over the channel of the wireless connection;
- and
- transmitting, to the base station, a request to use the second transmission power level for the future downlink communication over the channel of the wireless connection.
A user device comprising:
- a processor;
- a hardware-based transceiver;
- and
- a computer-readable storage medium comprising instructions executable by the processor to configure the processor to:
- determine a signal-to-interference-plus-noise ratio (SINR) of a downlink communication from a base station over a channel of a wireless connection;
- compare the SINR of the downlink communication with a threshold SINR for a modulation and coding scheme (MCS);
- determine, based on the comparison, a change in transmission power level to request for a future downlink communication over the channel of the wireless connection;
- and
- transmit, to the base station and using the hardware-based transceiver, a request for the change in the transmission power level for the future downlink communication over the channel of the wireless connection.
A base station comprising:
- a processor;
- a hardware-based transceiver;
- and
- a computer-readable storage medium comprising instructions executable by the processor to configure the processor to:
- transmit, to a user device and using the hardware-based transceiver, a downlink communication over a channel of a wireless connection with the user device, the downlink communication transmitted with a first transmission power level;
- receive, from the user device and using the hardware-based transceiver, a request for a second transmission power level for a future downlink communication;
- and
- transmit, to the user device and using the hardware-based transceiver, the future downlink transmission, the future downlink transmission transmitted at a third transmission power level that is based on the received request.
