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 idle state UEs and inactive state UEs may share a connection state UE usage tracking Reference Signal (TRS, tracking Reference Signal)/channel state indication Reference Signal (CSI-RS, channel State Information-Reference Signal) configuration, i.e., idle state UEs and inactive 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, when the UE is in a non-cell center or in some scenes, the UE can perform fine synchronization by receiving SSBs of 3 periods; this results in a relatively low synchronization efficiency. In the embodiments of the present disclosure, in order to improve synchronization efficiency, an information transmission method is proposed, where a TRS/CSI-RS that can be configured for a UE is expected to synchronize with fewer SSBs (e.g., SSBs that can pass through one cycle). That is, idle state UEs and inactive state UEs may synchronize using shared TRS/CSI-RS assistance.

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 shared TRS/CSI-RS is at least used for carrying out corresponding operation on the beam associated with the shared TRS/CSI-RS by idle state UE and/or inactive state UE.

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

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.

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

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

The frequencies of the base station and the UE physical crystal oscillator have small deviation, and the complete consistency cannot be realized, so that the radio frequency carrier signals received by the UE have phase deviation; on the demodulated symbol constellation of the received subcarriers, a rotation in phase is exhibited, i.e., the received modulation symbols deviate from a certain phase angle, due to accumulation of frequency offset over 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.

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

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.

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

In some embodiments, one or more shared TRS/CSI-RS may be included in the signal configuration information. In some embodiments, one TRS/CSI-RS may be associated with one or more beams. In some embodiments, 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 information may be used to indicate the beam. The beam information may be information uniquely indicating a beam. For example, the beam information may be used to indicate the identity of the beam, etc.

In some embodiments, the UE may determine a 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 information carried in the measurement instruction information of the shared TRS/CSI-RS can explicitly instruct the beam associated with the shared TRS/CSI-RS. The UE may accurately determine the beam with which the shared TRS/CSI-RS is associated based on the beam information.

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

indication information indicating an Index of the SSB;

indication information of QCL parameters indicating the Index.

SSB index may be used to uniquely identify a beam.

The quasi co-sited (QCL) may indicate a beam information reference signal Identity (ID), and may also indicate at least one of an antenna port, an antenna panel, a transmitting and receiving point, and an Identity (ID) of a physical cell to which the beam corresponds. In this way, the beam indication is made more accurate.

The UE may determine a beam to share the TRS/CSI-RS association based on the beam information. In this way, the UE may accurately determine the beam to which the shared TRS/CSI-RS is associated.

In one embodiment, the method further comprises:

And 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 of different TRS/CSI-RSs with beam information of different beams based on the signal configuration information.

And the UE determines the shared TRS/CSI-RS associated with the current beam according to the beam information of the current beam.

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

Thus, the UE determines the shared TRS/CSI-RS corresponding to the current beam based on the corresponding relation between the beam information and the shared TRS/CSI-RS, and accuracy of determining the shared TRS/CSI-RS corresponding to the current beam is improved.

After the UE determines the shared TRS/CSI-RS associated with the current beam, the UE may employ the shared TRS/CSI-RS for synchronization or wireless signaling in response to the UE detecting the shared TRS/CSI-RS associated with the current beam.

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 SSB for synchronization or radio signal measurements. In the related art, the UE needs to use 3 SSB periods for synchronization; the technical scheme of the embodiment of the disclosure adopts shared TRS/CSI-RS for synchronization, and only one SSB period is needed. Therefore, the shared TRS/CSI-RS synchronization is adopted, so that the wake-up time of the UE can be reduced, and the power consumption of the UE is reduced.

The UE may also use 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 UE adopts SSB to synchronize;

and the UE adopts the SSB to measure wireless signals.

The method includes determining, in response to the UE, that the current beam does not have an associated shared TRS/CSI-RS based on the signal configuration information. The UE may employ SSB for synchronization or wireless signaling.

In one embodiment, the method further comprises: and sending an effective indication for indicating whether the beam information is effective or not.

In the disclosed embodiments, the validation indication may be carried in any appropriate signaling, which is not limited by the disclosed embodiments. For example, the validation indication may be carried in the signal configuration information.

The validation indication may indicate whether beam information of the shared TRS and/or CSI-RS associated beam configured by the signal configuration information is validated. If validated, the UE may determine beam information for beams associated with different shared TRSs and/or CSI-RSs based on the signal configuration information; otherwise, the UE no longer determines beam information for the beams associated with the different shared TRSs and/or CSI-RSs based on the signal configuration information.

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

transmitting a system message carrying the signal configuration information;

or (b)

And sending the RRC signaling carrying the signal configuration information.

The signal configuration information may be carried in a system message or an RRC message. The signal configuration information can occupy reserved bits of the system message or the RRC message, so that the information carrying capacity of the system message or the RRC message is increased, and the utilization efficiency of the system message or the RRC message is improved.

The signal configuration information may also be carried by a new system message or RRC message.

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: and the shared TRS/CSI-RS is at least used for carrying out corresponding operation on the beams associated with the shared TRS/CSI-RS by the idle state UE and/or the non-active state UE.

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 carrying the beam information in the measurement indication information of the shared TRS/CSI-RS, the beam associated with the shared TRS/CSI-RS can be explicitly indicated. The UE may accurately determine the beam with which the shared TRS/CSI-RS is associated based on the beam information.

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

indication information indicating an Index of the SSB;

indication information of QCL parameters indicating the Index.

SSB index may be used to uniquely identify a beam.

The UE may determine a beam to share the TRS/CSI-RS association based on the beam information.

In this way, the UE may accurately determine the beam to which the shared TRS/CSI-RS is associated.

and adopting the SSB to measure wireless signals.

In one embodiment, the method further comprises: and receiving an validation instruction, and determining whether the beam information is validated according to the validation instruction.

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

In one embodiment, the receiving signal configuration information of the shared TRS/CSI-RS includes:

receiving a system message carrying the signal configuration information;

or (b)

And receiving the RRC signaling carrying the signal configuration information.

The signal configuration information may be carried in a system message or an RRC message.

The signal configuration information can occupy reserved bits of the system message or the RRC message, so that the information carrying capacity of the system message or the RRC message is increased, and the utilization efficiency of the system message or the RRC message is improved.

The signal configuration information may also be carried by the newly added system message and/or the RRC message.
