Abstract
The present disclosure relates to an electronic device, a wireless communication method, and a computer-readable medium. According to one embodiment, provided is an electronic device comprising a processing circuit and used for a user equipment side; the processing circuit is configured to control to transmit a non-precoded first uplink reference signal, receive feedback by a base station regarding the first uplink reference signal, and sending, on the basis of said feedback, a pre-coded second uplink reference signal.
Claims19
An electronic device for user equipment side, comprising processing circuitry configured to perform control to:
- transmit with a first period a first uplink reference signal which is non-precoded;
- receive a feedback from a base station with respect to the first uplink reference signal;
- and
- transmit, based on the feedback, with a second period shorter than the first period, a second uplink reference signal which is precoded.
An electronic device for user equipment side, comprising processing circuitry configured to perform control to:
- transmit a first uplink reference signal which is non-precoded;
- receive a feedback from a base station with respect to the first uplink reference signal;
- and
- transmit, based on the feedback, a second uplink reference signal which is precoded,
- wherein the processing circuitry is configured to transmit the first uplink reference signal in a power boosting manner,
- the power boosting manner comprises:
- in an orthogonal frequency division multiplexing symbol containing the first uplink reference signal, concentrating power to a resource element carrying the first uplink reference signal;
- or
- the power boosting manner comprises:
- transmitting only one uplink reference signal port in one orthogonal frequency division multiplexing symbol containing the first uplink reference signal.
An electronic device for user equipment side, comprising processing circuitry configured to perform control to:
- transmit a precoded first uplink reference signal by using two or more uplink reference signal resources;
- receive a feedback from a base station with respect to the first uplink reference signal;
- and
- transmit, based on the feedback, a precoded second uplink reference signal.
A wireless communication method for user equipment side, comprising:
- transmitting a precoded first uplink reference signal by using two or more uplink reference signal resources;
- receiving a feedback from a base station with respect to the first uplink reference signal;
- and
- transmitting, based on the feedback, a precoded second uplink reference signal.
