As shown in fig. 1, the ue includes a user terminal 11 and a base station 12, where the user terminal 11 may be a ue (user equipment), for example: the terminal side Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present invention.

step S210, a first MAC CE (Medium Access Control Element) signaling is generated, where the first MAC CE signaling is used to activate an SCell of the UE and trigger sending of a preset aperiodic reference signal to the UE.
In practical application, an SCell of a UE needs to be activated, and the activated SCell can provide wireless resources for the UE. In order to activate the SCell, the network side device generates a first MAC CE signaling, where the first MAC CE signaling may activate the SCell and trigger transmission of a preset aperiodic reference signal to the UE.
Because the first MAC CE signaling is not physical layer signaling, the demodulation time is longer when the UE demodulates the first MAC CE signaling for SCell activation. If the SCell is configured with a periodic reference signal, the activation delay of the SCell may be increased by the period of one reference signal for the longest time, resulting in that the UE cannot synchronize with the SCell quickly. Therefore, in the embodiment of the present invention, the first MAC CE signaling is used to trigger sending of the preset aperiodic reference signal to the UE, so as to effectively avoid the problem of long activation delay caused by the periodic reference signal.

The network side equipment configures a preset non-periodic reference signal, and after the first MAC CE signaling is sent, the preset non-periodic reference signal is sent at the time corresponding to the sending time offset value of the preset non-periodic reference signal relative to the first MAC CE signaling.

In practical application, an SCell of a UE needs to be activated, and the activated SCell can provide wireless resources for the UE. The UE needs to receive the reference signal on the activated SCell, and if there is no signaling indication or protocol specification, the UE cannot receive the reference signal on the deactivated SCell.
The MAC CE signaling is used for activating the UE, and because the MAC CE signaling is not physical layer signaling, the demodulation time is longer when the UE demodulates the MAC CE signaling to activate the SCell. If the aperiodic reference signal is configured for the UE, the SCell is not activated when the UE receives the aperiodic reference signal, which causes UE timing disorder. Therefore, in the embodiment of the present invention, the first DCI signaling is used to trigger sending of a preset aperiodic reference signal to the UE, and when the UE receives the first DCI signaling and the SCell of the UE is not activated, the UE is indicated to receive the preset aperiodic reference signal on the inactive SCell, so that the problem of UE timing disorder is effectively avoided.
In an embodiment of the present invention, the predetermined aperiodic reference signal includes one of the following: the system comprises an AP TRS and an AP CSI-RS, wherein the AP TRS is used for carrying out time-frequency tracking on the SCell, and the AP CSI-RS is used for carrying out channel measurement on the SCell.
The first DCI signaling includes, but is not limited to, the following two:

in the embodiment of the invention, a first DCI signaling is used for triggering the sending of a preset aperiodic reference signal to UE; and transmitting the preset aperiodic reference signal at a time corresponding to a transmission time offset value of the preset aperiodic reference signal relative to the first DCI signaling, wherein the transmission time offset value is used for indicating a time difference between the transmission of the first DCI signaling and the transmission of the preset aperiodic reference signal.
The network side equipment configures a preset aperiodic reference signal, and sends the preset aperiodic reference signal after sending the first DCI signaling and at the time corresponding to the sending time offset value of the preset aperiodic reference signal relative to the first DCI signaling.
For example, the aperiodic reference signal is preset to be an AP CSI-RS. And the network side equipment configures an AP CSI-RS, and the transmission time offset value of the AP CSI-RS relative to the first DCI signaling is Y. The network side device transmits the AP CSI-RS at time (t + Y) after transmitting the first DCI signaling at time t.
In order to enable the UE to accurately receive the preset aperiodic reference signal, a transmission time offset value of the preset aperiodic reference signal needs to be indicated to the UE.

In order to enable the UE to accurately receive one preset aperiodic reference signal, BWP of the preset aperiodic reference signal needs to be indicated to the UE.

The network side equipment configures a plurality of preset aperiodic reference signals, and after the first DCI signaling is sent, each preset aperiodic reference signal is sent at the moment corresponding to the sending time offset value of each preset aperiodic reference signal in the plurality of preset aperiodic reference signals relative to the first DCI signaling.

The UE transmits the AP CSI-RS 1 at time (t + Y1) after transmitting the first DCI signaling at time t; transmitting AP CSI-RS2 at the time (t + Y2); the AP CSI-RS 3 is transmitted at time (t + Y3).
In order to enable the UE to accurately receive the plurality of preset aperiodic reference signals, it is necessary to indicate a set of transmission time offset values of the plurality of preset aperiodic reference signals to the UE.
In an embodiment of the present application, the method further includes: indicating to the UE to transmit a set of time offset values;

In order to enable the UE to accurately receive the plurality of preset aperiodic reference signals, a BWP set of the plurality of preset aperiodic reference signals needs to be indicated to the UE.
It should be noted that, the manner of indicating the BWP sets of the multiple preset aperiodic reference signals to the UE may be determined according to practical situations, and is not limited herein.

The UE receives a first DCI signaling sent by network side equipment, and then triggers and receives a preset non-periodic reference signal according to the first DCI signaling, and indicates the UE to receive the preset non-periodic reference signal on an inactive SCell under the condition that the UE receives the first DCI signaling and the SCell of the UE is inactive.
In an embodiment of the present invention, the predetermined aperiodic reference signal includes one of the following: the system comprises an AP TRS and an AP CSI-RS, wherein the AP TRS is used for carrying out time-frequency tracking on the SCell, and the AP CSI-RS is used for carrying out channel measurement on the SCell.

And after receiving the first DCI signaling, the UE receives the preset aperiodic reference signal at the moment corresponding to the transmission time offset value of the preset aperiodic reference signal relative to the first DCI signaling.
For example, the aperiodic reference signal is preset to be an AP CSI-RS. The transmission time offset value of the AP CSI-RS with respect to the first DCI signaling is Y. The UE receives the AP CSI-RS at time (t + Y) after receiving the first DCI signaling at time t. If the SCell is not activated at time (t + Y), the UE may receive the AP CSI-RS on the inactive SCell.
