An application scenario of the embodiment of the present disclosure is that the UE in the idle state and the UE in the inactive state can share the tracking reference signal (TRS, Tracking Reference Signal)/Channel State Indication Reference Signal (CSI-RS, Channel State Information-Reference used by the UE in the connected state) Signal) configuration, that is, idle UEs and inactive UEs can use shared TRS/CSI-RS.

Connected UEs use TRS/CSI-RS to actually face a cell or a group of UEs, so the TRS/CSI-RS configuration does not consider the relationship with PO.

In the related art, when the UE is not in the center of the cell or in some scenarios, the UE can perform fine synchronization by receiving SSBs for 3 periods; this results in a relatively low synchronization efficiency. In the embodiment of the present disclosure, in order to improve the synchronization efficiency, an information transmission method is proposed, and it is expected that the TRS/CSI-RS configured for the UE can be synchronized through fewer SSBs (for example, a period of SSBs can be used). That is, idle state UEs and inactive state UEs can use shared TRS/CSI-RS assistance for synchronization.

As shown in FIG. 2, this exemplary embodiment provides an information transmission method, which can be applied to a base station of a cellular mobile communication system, including:

Step 201: Send the signal configuration information of the shared tracking reference signal TRS/channel state information reference signal CSI-RS, wherein the signal configuration information includes at least: beam information of the beam associated with the shared TRS/CSI-RS wherein , the shared TRS/CSI-RS is at least used for the idle state UE and/or the inactive state UE to perform corresponding operations on the beam associated with the shared TRS/CSI-RS.

In some embodiments, the shared TRS/CSI-RS is at least used for synchronization of idle UEs and/or inactive UEs.

Here, the UE may be a mobile phone terminal or the like that uses a cellular mobile communication technology to perform wireless communication. The base station may be a communication device that provides an access network interface to a UE in a cellular mobile communication system.

In the measurement of wireless signals, the UE may measure the TRS/CSI-RS sent by the base station.

The CSI-RS can be used for the UE to obtain at least one of the following parameters: channel status, beam management, mobility management, rate matching, and the like.

The frequency of the physical crystal oscillator of the base station and the UE will have a small deviation, and it is impossible to be completely consistent, which will cause the radio frequency carrier signal received by the UE to have a phase deviation; on the demodulation symbol constellation diagram of the received subcarrier , which manifests as a rotation in phase, that is, the received modulation symbol deviates from a certain phase angle, which is caused by the accumulation of frequency offset in time. At this time, a tracking reference signal (TRS) is required to track the rotational phase of other data signals. TRS is a multi-period CSI-RS, to be precise, a 4-1 port, 3 CSI-RS density, NZP-CSI-RS located in two consecutive time slots, two time in one time slot The minimum interval of TRS is 4 OFDM symbols, and the interval is 4 subcarriers in the frequency domain. Errors in frequency and time can be estimated from TRS. The received data compensates for these errors, and the original transmitted modulation coordinates can be rotated back.

Here, the shared TRS/CSI-RS may be the TRS/CSI-RS used by idle UEs and/or inactive UEs and shared with connected UEs. The idle state UE and/or the inactive state UE may monitor the TRS/CSI-RS at the shared TRS/CSI-RS timing with the connected state UE.

A beam is a communication resource, which can be a wide beam, a narrow beam, or other types of beams. The beam can be formed by beamforming technology with a specific direction of the beam. Here, the beamforming technology may include, but is not limited to, a numerical beamforming technology, an analog beamforming technology, a hybrid digital-analog beamforming technology, and the like.

In an embodiment, the signal configuration information includes at least: beam information of a beam associated with the shared TRS/CSI-RS. In one embodiment, the signal configuration information includes at least: beam information of two or more beams associated with the shared TRS/CSI-RS; wherein each of the shared TRS/CSI-RS is associated with The beam information of the beams is not exactly the same or not at all.

In some embodiments, the signal configuration information may include one or more shared TRS/CSI-RS. In some embodiments, one TRS/CSI-RS may be associated with one or more beams. In some embodiments, different shared TRS/CSI-RS may be associated with different beams. The base station can transmit different shared TRS/CSI-RS through different beams. Beam information can be used to indicate beams. The beam information may be the information that uniquely indicates the beam. For example, the beam information may be used to indicate the identity of the beam, and the like.

In some embodiments, the UE may determine the beam associated with the shared TRS/CSI-RS based on the beam information. For example, the UE may determine a beam for receiving the shared TRS/CSI-RS based on the beam information, thereby receiving the shared TRS/CSI-RS.

In this way, the beam associated with the shared TRS/CSI-RS can be explicitly indicated by the beam information carried in the measurement indication information of the shared TRS/CSI-RS. The UE can accurately determine the beam associated with the shared TRS/CSI-RS based on the beam information.

In one embodiment, the beam information includes at least one of the following:

Indication information indicating the index Index of the SSB;

In this way, the indication of the beam is made more accurate.

The UE may determine the beams sharing the TRS/CSI-RS association based on the beam information. In this way, the UE can accurately determine the beams that share the TRS/CSI-RS association.

In one embodiment, the method further includes:

The UE determines the shared TRS/CSI-RS associated with the current beam according to the beam information of the current beam based on the signal configuration information.

In one embodiment, the UE may determine the correspondence between different TRS/CSI-RS and beam information of different beams based on the signal configuration information.

Exemplarily, the UE determines the shared TRS/CSI-RS corresponding to the SSB index and/or the QCL parameter from the signal configuration information according to the SSB index and/or the QCL parameter of the beam information of the current beam.

In this way, the UE determines the shared TRS/CSI-RS corresponding to the current beam based on the correspondence between the beam information and the shared TRS/CSI-RS, and improves the accuracy of determining the shared TRS/CSI-RS corresponding to the current beam.

In one embodiment, the shared TRS/CSI-RS is at least used for wireless signal measurements by idle UEs and/or inactive UEs for beams associated with the shared TRS/CSI-RS.

After the UE determines the shared TRS/CSI-RS associated with the current beam, in response to the UE detecting the shared TRS/CSI-RS associated with the current beam, the UE may use the shared TRS/CSI-RS for synchronization or radio signal measurement.

Here, the wireless signal measurement may be an RRM measurement.

In response to the UE determining that the current beam has an associated shared TRS/CSI-RS, the UE may no longer use the SSB for synchronization or radio signal measurements. Because in the related art, the UE needs to use 3 SSB cycles for synchronization; while the technical solutions of the embodiments of the present disclosure use shared TRS/CSI-RS for synchronization, and only one SSB cycle is required. Therefore, the use of shared TRS/CSI-RS synchronization can reduce the wake-up time of the UE and reduce the power consumption of the UE.

The UE may also use the SSB for synchronization or radio signal measurements in response to the UE determining that the current beam has an associated shared TRS/CSI-RS.

The validation indication may indicate whether the beam information of the beam associated with the shared TRS and/or CSI-RS configured by the signal configuration information is valid. If it takes effect, the UE may determine the beam information of the beams associated with different shared TRS and/or CSI-RS based on the signal configuration information; otherwise, the UE will no longer determine the beams of the beams associated with different shared TRS and/or CSI-RS based on the signal configuration information information.

The valid indication may indicate with different values whether the shared TRS/CSI-RS is associated with beam information of different beams. For example, "0" is used to indicate that the beam information is not valid, and "1" is used to indicate that the beam information is valid; or, "1" may be used to indicate that the beam information is not valid, and "0" is used to indicate that the beam information is valid.
