Description

Technical Field

[0002] After connecting to a communication network, user equipment (UE) still needs to continuously search for and measure the radio channel quality of neighboring cells so that it can switch at the appropriate time. In related technologies, a measurement gap mechanism is defined for neighboring cell mobility measurements. The UE will perform neighboring cell measurements based on the measurement gap configured by the network equipment. In other words, a certain period of time, namely the measurement gap, is reserved. During this gap, the UE will not send or receive any data, but will tune the receiver to the frequency of the neighboring cell to perform neighboring cell measurements. When the gap time expires, it will switch to the current cell. In implementation, in the Radio Resource Control_CONNECTED (RRC_CONNECTED) state, the UE can perform neighboring cell mobility measurements based on the Synchronization Signal Block (SSB) and the Channel State Information Reference Signal (CSI-RS).

[0018] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation on the present application.

[0019] Figure 1 Flow schematic diagram of an inter-cell measurement method provided by an embodiment of the present application, which is executed by a UE, as Figure 1 shown, the inter-cell measurement method includes the following steps:

[0020] S101, obtain at least one measurement gap combination configured for the UE.

[0021] When performing inter-cell mobility measurement based on SSB, the UE performs inter-cell mobility measurement according to the configured SSB-based Radio Resource Management (RRM) measurement timing configuration (SSB based RRM Measurement Timing Configuration, SMTC), where SMTC can be configured with a length of 1-5 subframes. For inter-cell measurement based on CSI-RS, the CSI-RS resources can be sent in any time slot with a period of 5 ms, 10 ms, 20 ms or 40 ms. However, the length of the measurement gap in the related art is {FR1: 3 ms, 4 ms and 6 ms} and {FR2: 2.5 ms, 3.5 ms and 5.5 ms}, and the duration of these measurement gaps mainly considers the inter-cell mobility measurement based on SSB. However, for the inter-cell mobility measurement based on CSI-RS, the length of the measurement gap may not cover the length of the CSI-RS resources, affecting the measurement performance.

[0022] In the embodiments of the present application, in order to take into account the mobility measurements of neighboring cells for both the SSB-based and CSI-RS-based methods, at least one measurement gap combination is configured for the UE by the network device or protocol convention, and the at least one configured measurement gap combination is sent to the UE. Optionally, the network device may configure at least one measurement gap combination for the UE through measurement configuration signaling, such as the IE MeasConfig signaling. That is, the measurement configuration signaling carries at least one measurement gap combination configured for the UE. In some implementations, the network device synchronously sends the configuration parameters of the measurement gap combination to the UE together with the SSB resources and CSI-RS resources. In some implementations, the network device may send the configuration information of the measurement gap combination to the UE through the IE MeasConfig signaling before or after sending the SSB resources and CSI-RS resources to the UE.

[0023] Optionally, the measurement gap combination includes at least a measurement gap length (MGL) and a measurement gap repetition period (MGRP).

[0024] In a possible implementation, one measurement gap combination is configured for the UE. The MGL in the measurement gap combination configured by the network device is the larger value of the resource lengths of the SMTC and the CSI-RS resources. That is, considering the mobility measurements of neighboring cells based on SSB and CSI-RS, the configured MGL can be greater than or equal to the length of the CSI-RS resources, so as to enable the measurement of the CSI-RS signal.

[0025] It should be noted that the UE can perform mobility measurements on neighboring cells on multiple carrier frequencies. The configuration of the SMTC is based on the carrier frequency configuration, and different carriers can be configured with different SMTC periods, lengths, and offset values. D SMTC,i Denotes the configured length of the SMTC on carrier i. D CSI-RS,i Denotes the length of the CSI-RS resources on carrier i. The maximum value is determined by comparing the lengths of all SMTCs and all CSI-RS resources and is configured as the MGL in the measurement gap combination. For example, through MAX(D SMTC,i , D CSI-RS,i ) to determine the maximum value. Optionally, the maximum value can be determined separately from all SMTCs and the maximum value of the lengths of all CSI-RS resources, and then the larger value is determined from the two maximum values and configured as the MGL in the measurement gap combination. For example, through MAX(MAXD SMTC,i , MAXD CSI-RS,i ).

[0026] In another possible implementation, the network device configures measurement gap combinations for the UE for SSB mobility measurement and for CSI-RS mobility measurement respectively, where each measurement gap combination includes its own MGL and MGRP. When configuring the measurement gaps, for neighbor cell mobility measurements based on both SSB and CSI-RS simultaneously, the MGL within each respective measurement gap combination can meet the length requirements for neighbor cell mobility measurement.

[0027] S102, perform neighbor cell measurements based on SSB and / or CSI-RS according to the measurement gap combination.

[0028] After obtaining the configuration information of the measurement gap combination sent by the network device, the UE can obtain the MGL and MGRP from the measurement gap combination, and perform neighbor cell mobility measurement according to the MGL and MGRP.

[0029] Optionally, the UE performs mobility measurement on the SSB signals corresponding to the SSB resources according to the MGL within each MGRP. Further, based on the quality of the measured SSB signals, a suitable cell is selected for handover.

[0030] Optionally, the UE performs mobility measurement on the CSI-RS signals corresponding to the CSI-RS resources according to the MGL within each MGRP. Further, based on the quality of the measured CSI-RS signals, a suitable cell is selected for handover.

[0031] Optionally, the UE simultaneously performs mobility measurement on the SSB signals corresponding to the SSB resources and the CSI-RS signals corresponding to the CSI-RS resources according to the MGL within each MGRP. Further, based on the quality of the measured SSB signals and CSI-RS signals, a suitable cell is selected for handover.

[0032] In the embodiments of this application, the UE obtains at least one measurement gap combination configured for the UE, and the UE performs neighbor cell measurement based on SSB and / or CSI-RS according to the measurement gap combination. By configuring the measurement gap combination to take into account neighbor cell mobility measurements in both ways based on SSB and CSI-RS, it is convenient for the UE to obtain a suitable cell for handover.

[0033] The embodiments of this application provide another neighbor cell measurement method. Figure 2 It is a schematic flow diagram of another neighbor cell measurement method provided by the embodiments of this application, and is executed by the UE. As Figure 2 shown, this neighbor cell measurement method includes the following steps:

[0034] S201, receive a first measurement gap set configured for SSB neighbor cell measurement and a second measurement gap set configured for CSI-RS cell measurement sent by a network device.

[0035] The network device configures two measurement gap sets in a configuration signaling. One of the measurement gap sets is used for SSB neighbor cell measurement and can be called the first measurement gap set. For example, it can be labeled as gap pattern#1 = {MGL SSB,i , MGRP SSB,i}, and the other measurement gap set is used for CSI-RS neighbor cell measurement and can be called the second measurement gap set, gap pattern#2 = {MGL CSI-RS,i , MGRP CSI-RS,i}.

[0036] It should be noted that the UE can perform mobility measurements on neighbor cells on multiple carrier frequencies. For the first measurement gap set, the maximum value among the configured lengths of SMTC on each carrier can be configured as MGL in gap pattern#1 SSB,i , where MGL SSB,i is used to represent the configured length of SMTC on carrier i, and the configured length of SMTC on this carrier i is the maximum length. For the second measurement gap set, the maximum value among the lengths of CSI-RS resources on each carrier can be configured as MGL in gap pattern#2 CSI-RS,i , where MGL CSI-RS,i is used to represent the length of CSI-RS resources on carrier i, and the length of CSI-RS resources on this carrier i is the maximum resource length.

[0037] Optionally, the network device configures the sum of MGL and MGRP of the first measurement gap set and the second measurement gap set based on the SSB resources and CSI-RS resources allocated to the UE.

[0038] S202, in response to the SSB resources and the CSI-RS resources not overlapping in the time domain, measure the SSB signal corresponding to the SSB resources according to the first measurement gap set, and measure the CSI-RS signal corresponding to the CSI-RS resources according to the second measurement gap set.

[0039] S203, in response to the SSB resources and the CSI-RS resources overlapping in the time domain, select one from the first measurement gap set and the second measurement gap set as the target measurement gap set to be used during measurement.

[0040] In implementation, there may be a situation where the SSB resources and CSI-RS resources configured by the network device for the UE overlap in the time domain. In the embodiments of the present application, the UE can determine whether the SSB resources and CSI-RS resources overlap in the time domain based on the configuration information of the SSB resources and CSI-RS resources.

[0041] Optionally, in response to the SSB resources and CSI-RS resources not overlapping in the time domain, it means that the UE can separately perform neighbor cell measurements based on the SSB and neighbor cell measurements based on the CSI-RS in the time domain. In this case, at the measurement moment corresponding to the SSB resources, the UE can measure the SSB signals corresponding to the SSB resources according to the first measurement gap combination to implement mobility measurement of neighbor cells, and can also measure the CSI-RS signals corresponding to the CSI-RS resources according to the second measurement gap combination at the measurement moment corresponding to the CSI-RS resources.

[0042] Optionally, in response to the SSB resources and CSI-RS resources overlapping in the time domain, one is selected from the first measurement gap combination and the second measurement gap combination as the target measurement gap combination to be used during measurement. In some implementations, optionally, the MGL in the first measurement gap combination is compared with the measurement gap length in the second measurement gap combination, and the measurement gap combination corresponding to the larger of the two measurement gap lengths is used as the target measurement gap combination.

[0043] S204, measure the SSB signals corresponding to the SSB resources and / or the CSI-RS signals corresponding to the CSI-RS resources according to the target measurement gap combination.

[0044] By using the measurement gap combination corresponding to the larger of the two measurement gap lengths as the target measurement gap combination, it can be ensured that the measurement gap length is greater than or equal to the SMTC configured for neighbor cell mobility measurement based on the SSB, and at the same time greater than or equal to the length of the CSI-RS resources for neighbor cell mobility measurement based on the CSI-RS. In this way, the neighbor cell mobility measurements in both ways based on the SSB and based on the CSI-RS can be taken into account simultaneously.

[0045] After obtaining the target measurement gap combination, the UE can obtain the MGL and MGRP from the target measurement gap combination and perform neighbor cell mobility measurement according to the MGL and MGRP. That is to say, the UE performs mobility measurement on the SSB signals corresponding to the SSB resources and / or the CSI-RS signals corresponding to the CSI-RS resources within each MGRP according to the MGL. After obtaining the SSB signals and / or CSI-RS signals, an appropriate cell can be selected for handover based on the quality of the SSB signals and / or CSI-RS signals.

[0046] In an embodiment of the present application, the UE receives a first measurement gap combination configured by the network device for SSB-based neighbor cell measurement and a second measurement gap combination configured for CSI-RS cell measurement. When the SSB resource and the CSI-RS resource do not overlap in the time domain, the UE performs SSB-based neighbor cell measurement based on the first measurement gap combination and CSI-RS-based neighbor cell measurement based on the second measurement gap combination. When the SSB resource and the CSI-RS resource overlap in the time domain, the UE uses the set with the largest MGL among the two measurement gap combinations to perform SSB-based and / or CSI-RS-based neighbor cell measurement. In this embodiment, when configuring the measurement gap combination, the neighbor cell mobility measurements in both SSB-based and CSI-RS-based manners are considered. And when the UE performs neighbor cell measurement, it uses the set with the largest MGL among the two measurement gap combinations, and also considers the duration requirements for SSB-based and CSI-RS-based neighbor cell mobility measurements, so that the UE can obtain a suitable cell for handover.

[0047] An embodiment of the present application provides another method for neighbor cell measurement. Figure 3 It is a schematic flowchart of another method for neighbor cell measurement provided by an embodiment of the present application, which is executed by the network device. As Figure 3 shown, the method for neighbor cell measurement includes the following steps:

[0048] S301: Send at least one measurement gap combination to the UE to instruct the UE to perform SSB-based and / or CSI-RS-based neighbor cell measurement according to the measurement gap combination.

[0049] The network device configures at least one measurement gap combination for the UE and sends the configured at least one measurement gap combination to the UE. Optionally, the network device may configure at least one measurement gap combination through the IE MeasConfig signaling. In some implementations, the network device synchronously sends the configuration parameters of the measurement gap combination, the SSB resource, and the CSI-RS resource to the UE. In some implementations, the network device sends the SSB resource and the CSI-RS resource to the UE, and then sends the configuration parameters of the measurement gap combination to the UE through the IE MeasConfig signaling.

[0050] Optionally, the measurement gap combination includes at least MGL and MGRP.

[0051] In a possible implementation, a measurement gap combination is configured for the UE. The network device compares the resource lengths of the SMTC corresponding to the neighboring cell measurement based on the SSB and the CSI-RS resources corresponding to the neighboring cell measurement based on the CSI-RS, and configures the larger value of the resource lengths of the SMTC and the CSI-RS resources as the MGL in the measurement gap combination. In this implementation, the MGL in the configured measurement gap combination is the larger value of the resource lengths of the SMTC and the CSI-RS resources. That is to say, considering the neighboring cell mobility measurements based on the SSB and the CSI-RS, the configured MGL can be greater than or equal to the length of the CSI-RS resources, so as to enable the measurement of the CSI-RS signal.

[0052] It should be noted that there can be multiple SMTCs corresponding to the neighboring cell measurement based on the SSB, denoted as D SMTC,i , and there can be multiple CSI-RS resources corresponding to the neighboring cell measurement based on the CSI-RS. The length of the CSI-RS resources is denoted as D CSI-RS,i , and the network device can obtain each SMTC corresponding to the neighboring cell measurement based on the SSB, and can also obtain the length of each CSI-RS resource. Further, by comparing the lengths of all SMTCs and all CSI-RS resources, the maximum value is determined and configured as the MGL in the measurement gap combination. For example, the maximum value is determined by MAX(D SMTC,i , D CSI-RS,i ). Optionally, the maximum value can be determined from all SMTCs respectively, and the maximum value of the lengths of all CSI-RS resources can be determined, and then the larger value is determined from the two maximum values and configured as the MGL in the measurement gap combination. For example, by MAX(MAXD SMTC,i , MAXD CSI-RS,i ).

[0053] In another possible implementation, the network device configures two measurement gap combinations for the UE. One is the first measurement gap combination configured for the neighboring cell measurement based on the SSB, and the other is the second measurement gap combination configured for the neighboring cell measurement based on the CSI-RS. Among them, each measurement gap combination includes its own MGL and MGRP. When configuring the measurement gap, considering the neighboring cell mobility measurements based on the SSB and the CSI-RS at the same time, the MGL within each respective measurement gap combination can meet the length requirements for the neighboring cell mobility measurement. For the second measurement gap combination configured for the neighboring cell mobility measurement based on the CSI-RS, the MGL can be greater than or equal to the length of the CSI-RS resources, so as to enable the measurement of the CSI-RS signal.

[0054] After obtaining the measurement gap combination sent by the network device, the UE can obtain the MGL and MGRP from the measurement gap combination and perform neighbor cell mobility measurement based on the MGL and MGRP.

[0055] In the embodiments of the present application, the UE receives at least one measurement gap combination configured for the UE by the network device and performs neighbor cell measurement based on SSB and / or based on CSI-RS according to the measurement gap combination. By configuring the measurement gap combination to take into account neighbor cell mobility measurement in both ways based on SSB and based on CSI-RS, it is convenient for the UE to obtain a suitable cell for handover.

[0056] Corresponding to the neighbor cell measurement methods provided in the above several embodiments, the present application also provides a neighbor cell measurement device.

[0065] Optionally, the measurement module 120 is further configured to compare the measurement gap lengths in the first measurement gap combination and the second measurement gap combination, and use the measurement gap combination corresponding to the larger of the two measurement gap lengths as the target measurement gap combination.

[0066] Optionally, the acquisition module 110 is further configured to receive measurement configuration signaling sent by a network device, where the measurement configuration signaling carries the at least one measurement gap combination.

[0067] In an embodiment of the present application, the UE receives at least one measurement gap combination configured for the UE by the network device, and performs neighbor cell measurement based on SSB and / or based on CSI-RS according to the measurement gap combination. By configuring the measurement gap combination to take into account neighbor cell mobility measurements in both the SSB-based and CSI-RS-based manners, it is convenient for the UE to obtain a suitable cell for handover.

[0072] Optionally, the sending module 210 is further configured to, in response to sending one of the measurement gap combinations to the UE, obtain the larger value of the resource lengths of the SMTC and CSI-RS resources corresponding to the neighbor cell measurement based on the SSB, and configure the measurement gap length in the measurement gap combination according to the larger value.

[0073] Optionally, the sending module 210 is further configured to send the UE a first measurement gap combination configured for the neighbor cell measurement based on the SSB and a second measurement gap combination configured for the neighbor cell measurement based on the CSI-RS.

[0074] Optionally, the sending module 210 is further configured to send measurement configuration signaling to the UE, where the at least one measurement gap combination is carried in the measurement configuration signaling.
