Execution bodies to which embodiments of the present disclosure relate include, but are not limited to: a UE such as a mobile phone terminal supporting cellular mobile communication, and a base station.

One application scenario of the embodiments of the present disclosure is that in the related art, idle state UEs and non-active state UEs may share a TRS/CSI-RS configuration for connection state UEs, i.e., idle state UEs and non-active state UEs may use a shared TRS/CSI-RS.

The connected UEs are actually cell-oriented or group of UEs using TRS/CSI-RS, so the TRS/CSI-RS configuration does not take into account the relationship with the POs.

In the related art, the UE performs fine synchronization by receiving SSB of 3 periods at the non-cell center;

if the UE knows that there is a configured TRS/CSI-RS, then synchronization can be through one cycle of SSB.

In the related art, the shared TRS/CSI-RS cannot be used for wireless signal measurement.

As shown in fig. 2, the present exemplary embodiment provides an information transmission method, which may be applied to a base station of a cellular mobile communication system, including:

step 201: transmitting signal configuration information of a shared Tracking Reference Signal (TRS)/channel state information (CSI-RS), wherein the signal configuration information at least comprises: and the measurement indication information is at least used for indicating the shared TRS/CSI-RS for wireless signal measurement by the idle state User Equipment (UE) and/or the inactive state UE.

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

The base station may configure shared TRS/CSI-RS for idle state UEs and/or inactive state UEs. And transmits the configuration information to the UE through the signal. The UE determines the shared TRS/CSI-RS based on the signal configuration information. The signal configuration information may be used to indicate transmission resources of the shared TRS/CSI-RS, including, but not limited to, time domain resources and/or frequency domain resources, etc. The base station may transmit signal configuration information to the UE through higher layer signaling. Here, the shared TRS/CSI-RS may be used at least for reception by the idle state UE and/or the inactive state UE, and may also be used for reception by the UE in a connected state.

The measurement indication information may be used to indicate a shared TRS and/or CSI-RS for wireless signal measurements by idle state UEs and/or inactive state UEs.

The measurement indication information may indicate whether the shared TRS and/or CSI-RS configured by the signal configuration information may be used for wireless signal measurement, e.g., the measurement indication information may indicate whether the shared TRS and/or CSI-RS configured by the signal configuration information may be used for wireless signal measurement by a UE in an inactive state and/or a UE in an idle state. The measurement indication information may indicate whether the shared TRS/CSI-RS can be used for radio signal measurement with different values. For example, a "0" indicates that the shared TRS/CSI-RS cannot be used for wireless signal measurement, and a "1" indicates that the shared TRS/CSI-RS can be used for wireless signal measurement; alternatively, "1" may be used to indicate that the shared TRS/CSI-RS cannot be used for wireless signal measurement, and "0" may be used to indicate that the shared TRS/CSI-RS can be used for wireless signal measurement;

The measurement indication information may also indicate transmission resources of the shared TRS/CSI-RS for radio signal measurement, or may indicate transmission resources of the shared TRS/CSI-RS that cannot be used for radio signal measurement.

The UE may determine, according to the measurement indication information, a shared TRS/CSI-RS that may be used for wireless signal measurement among the shared TRS/CSI-RS configured by the signal configuration information.

In radio signal measurement, the UE may make measurements for TRS/CSI-RS transmitted by the base station.

CSI-RS may be used for UE to acquire status of channels, beam management, mobility management, rate matching, etc.

The frequencies of the base station and the physical crystal oscillator of the UE have small deviation, and the frequencies cannot be completely consistent, so that the radio frequency carrier signals received by the UE have phase deviation, and the phase rotation is shown on the demodulation symbol constellation diagram of the received subcarriers, namely, the received modulation symbols deviate by a certain phase angle, which is caused by accumulation of frequency deviation in time. At this time, a tracking reference signal (tracking reference signal, TRS) is required to track the rotational phase of the other data signals. The TRS is a multi-period CSI-RS, namely a 4-1 port, 3 CSI-RS density, NZP-CSI-RS positioned in two continuous time slots, wherein the minimum interval of two TRSs in one time slot is 4 OFDM symbols, and the interval in the frequency domain is 4 subcarriers. The error in frequency and time can be estimated from the TRS. The received data compensates for these errors, i.e. the originally transmitted modulation coordinate position can be rotated back.

In this way, by measuring the indication information, at least the shared TRS/CSI-RS for indicating the UE in the idle state and/or the UE in the inactive state to perform radio signal measurement is determined. On the other hand, the UE can accurately select the shared TRS/CSI-RS for wireless signal measurement based on the measurement indication information, so that the wireless signal selection accuracy is improved.

Measurement relaxation may include, but is not limited to RRM measurement relaxation, and the like. RRM measurement is an important component of UE energy consumption and can be used for mobility management of UEs. For RRM measurement, power consumption is proportional to the measurement frequency and the number of measurement objects, including the number of SSBs measured, the number of cells, the number of frequencies, etc. In some cases, some RRM measurements by the UE are not necessary, and may increase the power consumption of the UE, increasing the power consumption. Measurement relaxation refers to reducing the measurement activity of the UE under certain conditions. Thereby effectively reducing the energy consumption of the UE. RRM measurement relaxation modes include, but are not limited to: the measurement period is increased, the number of measurement samples is reduced, the measurement target is reduced, and the like.

The measurement indication information may indicate the shared TRS/CSI-RS for the radio signal measurement for measurement relaxation.

Thus, by measuring the indication information, determining the shared TRS/CSI-RS for indicating at least the radio signal measurement for measurement relaxation by the UE in idle state and/or the UE in inactive state provides a method for explicitly indicating the shared TRS/CSI-RS for measurement relaxation, on the one hand, providing more radio signal choices for the UE to measure relaxation radio signal measurement. On the other hand, the UE can accurately select the shared TRS/CSI-RS for measurement of the relaxed radio signal based on the measurement indication information, thereby improving the radio signal selection accuracy.

Here, the measurement indication information may indicate a signal configuration of the shared TRS/CSI-RS that can be used for measuring the relaxed radio signal measurement.

Here, the signal configuration may include: transmission resource configuration of TRS/CSI-RS, identification of TRS/CSI-RS, and the like.

The UE may determine a shared TRS/CSI-RS that can be used to measure relaxed radio signal measurements based on the signal configuration indicated by the measurement indication information.

In this way, the UE can accurately determine the shared TRS/CSI-RS for measuring the relaxed radio signal measurement, improving the reliability of the radio signal measurement.

Here, the beam is a communication resource, and may be a wide beam, a narrow beam, or other types of beams. The beam may be a beam with a particular direction formed by a beamforming technique. Here, the beamforming technique may include, but is not limited to, a numerical beamforming technique, an analog beamforming technique, or a hybrid digital analog beamforming technique, etc.

Different shared TRSs/CSI-RSs may be associated with different beams. The base station may transmit different shared TRSs/CSI-RSs through different beams.

The beam configuration may include an identification of the beam or the like for uniquely indicating the configuration of the beam.

The UE may determine a beam of shared TRS/CSI-RS associations that can be used to measure relaxed radio signal measurements based on the measurement indication information.

The UE may first determine the beam for which radio signal measurements are to be made when making measurement relaxed radio signal measurements. The UE may first search for SSB associated with one beam and read SSB index, which may be used to uniquely identify the beam.

The UE may determine SSB index of the beam that can be used to measure the relaxed TRS/CSI-RS association of the radio signal measurement based on the measurement indication information.

If the SSB index indicated by the measurement indication information coincides with the index in the SSB of the beam currently detected by the UE, it may be determined that the TRS/CSI-RS may be used for measurement relaxed radio signal measurement of the current beam. The UE may use the TRS/CSI-RS indicated by the measurement indication information to make measurement-relaxed radio signal measurements for the current beam.

If the SSB index indicated by the measurement indication information is inconsistent with the index in the SSB of the current detected beam by the UE, the UE may use the monitored SSB to perform measurement-relaxed radio signal measurement of the current beam.

Thus, the UE can accurately determine the shared TRS/CSI-RS for the current beam measurement and loose wireless signal measurement, and the reliability of the current beam wireless signal measurement is improved.

The UE may employ only shared TRS/CSI-RS above the signal strength threshold for measurement relaxed radio signal measurements. When the signal strength of the configured shared TRS/CSI-RS is lower than the signal strength threshold, measurement relaxed wireless signal measurement may not be performed using the shared TRS/CSI-RS, but measurement relaxed wireless signal measurement may be performed using the monitored SSB.

The signal strength threshold may be a threshold of EPRE. The base station may configure the EPRE threshold of the TRS/CSI-RS, implicitly indicating that the UE may be used to measure the configuration of the relaxed TRS/CSI-RS. In response to the base station configuring the TRS/CSI-RS below the threshold of the EPRE, the UE employs the TRS/CSI-RS to measure the relaxed radio signal measurement.

In one embodiment, the method further comprises:

The UE needs to meet certain conditions to perform measurement-relaxed radio signal measurement. For example, when the mobility of the UE is below a predetermined threshold, a measurement-relaxed radio signal measurement may be performed. Here, the condition parameter may be used to characterize that the UE may perform a radio signal measurement that is measurement relaxed, needs to meet the condition. For example, the condition parameters may include a movement condition parameter such as a movement speed threshold. When the movement speed of the UE is below the movement speed threshold, a measurement-relaxed radio signal measurement may be performed.

The base station may send the condition parameters to the UE. The UE determines whether measurement relaxed radio signal measurements can be made based on the condition parameters. In response to the UE determining that measurement relaxed radio signal measurements can be made based on the condition parameters, the UE can employ the shared TRS/CSI-RS for measurement relaxed radio signal measurements.

As shown in fig. 3, the present exemplary embodiment provides an information transmission method, which may be applied to an idle state user equipment UE and/or an inactive state UE of a cellular mobile communication system, including:

step 301: receiving signal configuration information of a shared Tracking Reference Signal (TRS)/channel state information (CSI-RS), wherein the signal configuration information at least comprises: measuring indication information;

step 302: and determining the shared TRS/CSI-RS for measuring the wireless signals according to the measurement indication information.

The base station may configure shared TRS/CSI-RS for idle state UEs and/or inactive state UEs. And transmits the configuration information to the UE through the signal. The UE determines the shared TRS/CSI-RS based on the signal configuration information. The signal configuration information may be used to indicate transmission resources of the shared TRS/CSI-RS, including, but not limited to, time domain resources and/or frequency domain resources, etc. The base station may transmit signal configuration information to the UE through higher layer signaling. Here, the shared TRS/CSI-RS is at least used for receiving by the idle state UE and/or the inactive state UE, and may also be used for receiving by the UE in the connected state.

The measurement indication information may indicate whether the shared TRS and/or CSI-RS configured by the signal configuration information may be used for wireless signal measurement. The measurement indication information may indicate whether the shared TRS/CSI-RS can be used for radio signal measurement with different values. For example, a "0" indicates that the shared TRS/CSI-RS cannot be used for wireless signal measurement, and a "1" indicates that the shared TRS/CSI-RS can be used for wireless signal measurement; alternatively, "1" may be used to indicate that the shared TRS/CSI-RS cannot be used for wireless signal measurement, and "0" may be used to indicate that the shared TRS/CSI-RS can be used for wireless signal measurement;

In one embodiment, the method further comprises:

or alternatively, the process may be performed,

If the SSB index indicated by the measurement indication information coincides with an index in the SSB in the beam currently tracked or detected by the UE, it may be determined that the TRS/CSI-RS may be used for measurement relaxed radio signal measurement of the current beam. The UE may use the TRS/CSI-RS indicated by the measurement indication information to make measurement-relaxed radio signal measurements for the current beam.

If the SSB index indicated by the measurement indication information is inconsistent with the index in the SSB of the beam currently tracked or detected by the UE, the UE may employ the monitored SSB to perform measurement relaxed radio signal measurement of the current beam.

In one embodiment, the method further comprises:

determining the shared TRS/CSI-RS with a signal strength not lower than the signal strength threshold as the shared TRS/CSI-RS for the wireless signal measurement;

Or alternatively, the process may be performed,

In one embodiment, the method further comprises:

receiving and transmitting measurement condition information;

In one embodiment, the method further comprises:

For shared TRS/CSI-RS that are not configured for measurement, the UE continues to employ SSB for radio signal measurement. Here the wireless signal measurement may include: relaxed radio signal measurements are measured.

A specific example is provided below in connection with any of the embodiments described above:

1. the base station configures the TRS/CSI-RS signal configuration that can be used for idle state reference and further configures whether the reference signal can be used for measurement relaxation.

2. The method may further include configuring conditions for satisfying measurement relaxation so that the UE determines screening.

3. The base station explicitly gives the configuration of the TRS/CSI-RS, including the beam information, that can be used to measure the relaxation. In this way, measurement reliability can be improved.

4. For reference signals that are not configured for measurement, the UE continues to rely on SSB for measurement relaxation.

5. For configuration measurements, but the beam configuration is also consistent with the beam corresponding to the Index of the SSB tracked by the idlue, the configuration is validated.

6. The base station may also configure a reference signal EPRE threshold, implicitly indicating that the UE may be used to measure a relaxed reference signal configuration, i.e. TRS/CSI-RS sent by EPREs below a certain threshold, the UE is not used to measure relaxation.

7. The UE has a certain degree of power saving effect.
