Description

NR measuring method, device, terminal equipment and storage medium

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to an NR measurement method and apparatus, a terminal device, and a storage medium.

Background

5G New Wireless (5G New radio,5G NR) technology, abbreviated NR. Is a communication technology which is about to be commercially used on a large scale at present. At present, there are two networking modes of a 5G base station, one is independent networking (SA), and the other is non-independent Networking (NSA). The NSA is a method of deploying a 5G base station (G-Node B, gNB) on an existing 4G base station (Evolved Node B, eNB).

In NSA, when a User Equipment (UE) accesses a gbb or switches the gbb, NR measurement needs to be performed to determine whether a target gbb that satisfies a B1 event (quality of an adjacent cell is higher than a certain threshold) exists. The terminal device will then access or handover to the target gbb that satisfies the B1 event. When performing NR measurement, the eNB corresponding to the target gNB generally sends an NR band number of the target gNB to the terminal device through configuration information, and the terminal device performs NR measurement on the target gNB in an NR band corresponding to the NR band number.

However, since there is a part of the third Generation Partnership project (3 gpp) 36.331 protocol version of the eNB that is outdated, there is no NR band number in the configuration information that the eNB sends to the terminal device. The terminal equipment can only determine the frequency to be measured according to the frequency point, and further determine the NR frequency band number. However, the frequency determined according to the frequency point may correspond to a plurality of NR frequency segment numbers, and when performing NR measurement according to the frequency point, the terminal device cannot determine the NR frequency segment to be measured, which results in measurement failure.

Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

As used in this specification and the appended claims, the term "if" may be interpreted contextually as "when.. Or" upon "or" in response to a determination "or" in response to a detection ".

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather mean "one or more, but not all embodiments," unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

The NR measurement method provided by the application is suitable for a communication system comprising a plurality of base stations and at least one terminal device. Illustratively, as shown in fig. 1, the communication system includes a base station 1, a base station 2 and a terminal device. Wherein each base station comprises one eNB and one gNB. The terminal device may be a smart phone, a tablet computer, a wearable device, an Augmented Reality (AR)/Virtual Reality (VR) device, a vehicle-mounted terminal, and other devices supporting 5G communication.

Based on the communication system shown in fig. 1, a terminal device currently resides in an LTE cell of a base station, and searches whether there is an adjacent NR cell satisfying a B1 event through NR measurement, where the B1 event means that the quality of the adjacent NR cell is measured to be higher than a preset threshold. If a neighboring NR cell satisfying the B1 event is detected, the terminal device may be accessed to the NR cell.

It should be noted that, a range that can be covered by the signal of the eNB is an LTE cell, and a range that can be covered by the signal of the gNB is an NR cell. If the current terminal device does not access the NR cell, the adjacent NR cells refer to a plurality of NR cells that the terminal device can search for at the same time. If the current terminal equipment accesses the NR cell, the remaining NR cells which can be searched are all adjacent NR cells except the current resident NR cell.

One possible application scenario is illustrated here in connection with fig. 2.

As shown in fig. 2, in some embodiments, a terminal device (i.e., a user equipment UE) first sends an RRC connection request (RRC CONN REQ) to an eNB, then receives an RRC connection acknowledgement (RRC CONN SETUP) returned by the eNB, and after the RRC connection is successfully established, the terminal device sends an RRC SETUP success message (RRC CONN SETUP CMP) to the eNB. Then, a terminal equipment capability query command (UE CAP query) sent by the eNB is received, and the terminal equipment sends the NR capability information and the ENDC capability information of the terminal equipment to the eNB (UE CAP INFO) according to the query command. And finally, receiving B1 event configuration information (RRC CONN RECFG) sent by the eNB, wherein the B1 event configuration information comprises configuration information of a target NR cell, a threshold of a B1 event and the like. The configuration information of the target NR cell includes frequency point information and NR frequency band information of the target NR cell. After the terminal equipment completes the configuration of the B1 event, a configuration completion instruction (RRC CONN RECFG CMP) is sent to the eNB. The terminal device then performs NR measurement based on the Synchronization Signal and Physical Broadcast channel block (SSB) according to the configured B1 event. The SSB includes three parts, namely Primary Synchronization Signals (PSS), secondary Synchronization Signals (SSS), and Physical Broadcast Channel (PBCH), and can be used for downlink Synchronization. When the NR measurement result satisfies the B1 event, the terminal device adds the gNB satisfying the NR measurement result to an auxiliary cell group (SCG), thereby implementing inter-system handover and accessing to a 5G network.

In the above system handover procedure, the NR frequency band of the target NR cell may be absent in the configuration information of the target NR cell. In this case, the terminal device can only determine the frequency to be measured according to the frequency point information in the configuration information of the target NR cell, and further determine the NR frequency band number. However, the frequency determined according to the frequency point may correspond to a plurality of NR frequency segment numbers, and when performing NR measurement according to the frequency point, the terminal device cannot determine the NR frequency segment to be measured, which results in measurement failure.

For example, the configuration information of the B1 event includes configuration information (MeasObjectNR) of the target NR cell. If the eNB's 3gpp 36.331 protocol version is f20 or earlier, the configuration information sent by these enbs generally only includes the frequency point of the target NR cell and does not include the NR segment number. The frequency bins of the target NR cell may correspond to overlapping NR bin numbers. In an example, if the operating frequency band of the LTE cell is B20, the frequency point of the target NR cell is configured to 636918. The frequency point corresponds to a frequency value of 3553.770MHz, which is within the overlapping region of NR bin numbers n77 (3300 MHz-4200 MHz) and n78 (3300 MHz-3800 MHz). That is, the frequency point may correspond to n77 or n78, and the terminal device cannot determine whether the n77 frequency band or the n78 frequency band should be measured when performing NR measurement. The NR operating band number is specified in the 3gpp 38.104 protocol. The target NR cell may be a corresponding NR cell of the LTE cell currently camped on, or may be an adjacent NR cell, which is not limited herein.

In view of the above problem, the present application provides an NR measuring method, in which when configuration information of a target NR cell sent by a base station does not include an NR frequency band of the target NR cell, first endec information of a terminal device is obtained, where the endec information includes an NR frequency band number. And the terminal equipment carries out NR measurement on the target NR cell on the NR frequency band corresponding to the NR frequency band number. The NR frequency band for NR measurement is a frequency band corresponding to the determined NR frequency band number for NR measurement of the target NR cell. Therefore, when performing the NR measurement, the terminal device does not have measurement failure caused by the inconsistency between the measured NR frequency band and the NR frequency band supported by the base station, and the compatibility between the terminal device and the base station when performing the NR measurement is effectively improved, so that the application range of the NR measurement is wider.

The method provided by the present application is exemplarily described below with reference to specific embodiments.

Referring to fig. 3, the NR measuring method may be applied to the terminal device described above by way of example and not limitation.

S11, when the configuration information of the target NR cell sent by the base station does not include the NR frequency band of the target NR cell and the frequency point of the target NR cell in the configuration information corresponds to at least two NR frequency band numbers, acquiring first ENDC information of the terminal equipment.

For example only, and not by way of limitation, referring to the above example, if the base station has a 3gpp 36.331 protocol version f20 and f20 ago, the NR frequency band of the target NR cell may not be configured in the configuration information of the target NR cell. Therefore, when the frequency point of the target NR cell in the configuration information corresponds to at least two NR segment numbers, the terminal device cannot determine which NR segment number of the NR segment numbers should be measured.

Note that the endec refers to dual connectivity between the 4G radio access network and the 5G NR. The method is used for connecting the eNB and the gNB simultaneously when NSA networking is carried out. The ENDC information includes an LTE band number and an NR band number, which indicate a 4G band and a 5G band that the ENDC can support.

S12, the terminal device carries out NR measurement on the target NR cell on the NR frequency band corresponding to the frequency band number.

In some embodiments, the NR frequency band corresponding to the NR frequency band number in the first endec information may be an NR frequency band when performing NR measurement on the target NR cell. The measurement mode may be SSB-based interval (Gap) measurement or no-interval (NoGap) measurement. For example, if the NR frequency band to be measured is n78, the RRC of the terminal device initiates an NR measurement request to a physical layer (PHY) of the terminal device. And after receiving the NR measurement request, the PHY verifies whether ENDC information of the NR frequency band number and the currently resident LTE frequency band number during NR measurement of the target NR cell is ENDC information supported by the terminal equipment. If ENDC information supported by the terminal equipment is determined, the PHY starts to start Gap measurement or NoGAP measurement of NRSSB. And if the ENDC information is a combination which cannot be supported by the terminal equipment, ending the NR measurement.

The Gap measurement refers to setting preset measurement Gap time during measurement, and in the measurement Gap time, the terminal device does not send and receive any data, but adjusts the receiver to an NR frequency band corresponding to a target NR cell frequency point to measure the pilot frequency. And when the Gap time is measured, the receiver is transferred to the NR frequency band corresponding to the cell frequency point which is resided currently. And in the NoGap measurement, the receiver is directly tuned to a target NR cell without setting the Gap measurement time, and the measurement of the same frequency is carried out.

For example, if the NR frequency segment number corresponding to the frequency point of the currently camped NR cell is n78, and the NR frequency segment number of the target NR cell is also n78, the NoGap measurement may be performed. Or, if the NR frequency segment number corresponding to the currently camped NR cell frequency point is n77, and the NR frequency segment number of the target NR cell is n78, performing Gap measurement. Gap measurement is used in the case where the NR band number of the target NR cell is different from the NR band number corresponding to the currently camped NR cell, and nocap measurement is used in the case where the NR band number of the target NR cell is the same as the NR band number corresponding to the currently camped NR cell.

It should be noted that in S12, there are various ways for the terminal device to acquire the first endec, which are only used as examples and are not limited, and four possible acquisition ways are given below, and the acquisition of the first endec is explained.

Referring to fig. 4, the terminal device acquiring the first endec information may include:

and S111, acquiring an ENDC list of the terminal equipment and an LTE frequency band number of the base station.

It should be noted that the base station refers to an eNB currently residing in the LTE cell, and a frequency band number corresponding to a current working frequency band of the eNB is an LTE frequency band number of the base station. The ENDCs supported by the terminal devices are fixed. And determining the ENDC list of the terminal equipment according to the model of the terminal equipment or hardware information provided by the terminal equipment.

For example, the NR frequency band number of the NR frequency band that a certain type of terminal device can support is:

n1/n3/n28/n41/n77/n78/n79。

the LTE frequency band numbers of the LTE frequency bands that can be supported are:

FDD-LTE：B1/B2/B3/B4/B5/B6/B7/B8/B9/B12/B17/B18/B19/B20/B26/B28；TD-LTE：B34/B38/B39/B40/B41。

the frequency band represented by the NR frequency band number may be referred to in the 3gpp 38.104 protocol. The frequency band represented by the LTE frequency band number can be referred to in the 3gpp 36.101 protocol.

As an example, a corresponding list of NR bin numbers and bins is given here.

NR frequency band number	Uplink frequency band	Downlink frequency band

			n83	703MHz-748MHz	N/A
n84	1920MHz-1980MHz	N/A
			n86	1710MHz-1780MHz	N/A

After the number of the LTE frequency band and the number of the NR frequency band that can be supported by the terminal device are confirmed, each LTE frequency band and each NR frequency band of the terminal device may be combined into one piece of endec information, such as B20+ n77, B20+ n78, B18+ n79, and all endec information supported by the terminal device is an endec list of the terminal device.

It should be noted that, when the NR band numbers in the endec list of the terminal device are different from the NR band numbers corresponding to the frequency points in the same NR band number, the first endec acquisition manner is different. Wherein, the method is applied when the same NR frequency band number is 1. And the second method is applied when the number of the same NR frequency bands is greater than 1.

In one mode

With continued reference to fig. 4, in a first manner, the method includes:

and S112, when one NR frequency band number corresponding to the frequency point is the same in the NR frequency band numbers in the ENDC list of the terminal equipment, taking ENDC information consisting of the LTE frequency band number and the same NR frequency band number as first ENDC information.

In a possible implementation manner, the LTE band number of the currently camped base station may be obtained first, and then the endec information composed of the LTE band number and the NR band number may be obtained.

For example only and without limitation, if the LTE frequency band number of the currently camped base station is B20, the NR frequency band number in the ENDC list of the terminal device includes n66/n70/n77, the frequency point of the target NR cell is 636918, the corresponding frequency value is 3553.770MHz, and the terminal device is in the overlapping area of the frequency bands corresponding to the frequency band numbers n77 and n78. Thus bin 636918 corresponds to the two NR bin numbers n77 and n78. The same is n77 in the endec list and the corresponding frequency band number of the terminal device. B20+ n77 may be taken as the first endec information. At this time, the frequency band corresponding to the NR frequency band number n77 can be set as the frequency band when the NR measurement is performed by the target NR cell.

Since the first ENDC is acquired in combination with the ENDC capability of the terminal device, the frequency band corresponding to the NR frequency band number of the target NR cell is acquired for NR measurement. The ENDC formed by the LTE frequency band and the NR frequency band can be supported by the terminal equipment during NR measurement, so that the success probability of the NR measurement is effectively improved, and the measurement failure caused by incompatibility is reduced.

Mode two

With continued reference to fig. 4, in a second manner, the method includes:

s113, when at least two NR frequency band numbers corresponding to the frequency points are the same in the NR frequency band numbers included in the ENDC list of the terminal equipment, the LTE frequency band numbers and each same NR frequency band number sequentially form ENDC information as first ENDC information.

By way of example only, and not limitation, if NR frequency segment numbers that can be supported in the endec list of a certain model of terminal device are: n66/n70/n77/n78, the frequency point of the target NR cell is 636918, the corresponding frequency value is 3553.770MHz, and the target NR cell is located in the overlapping area of the frequency bands corresponding to the frequency band numbers n77 and n78. Thus bin 636918 corresponds to the two NR bin numbers n77 and n78. The same is n77 and n78 in the terminal device's endec list and the corresponding frequency band number. The same NR frequency band number in the endec information may be combined with the frequency band number of the currently camped LTE cell (e.g. B20) to form endec information, that is, the endec information may be B20+ n77 and B20+ n78. Then the NR frequency bands corresponding to n77 and n78 are respectively used as the frequency bands when NR measurement is performed by the target NR cell.

It should be noted that when NR measurement is performed, if there is no NR measurement result satisfying a B1 event, or there is an NR measurement result satisfying a B1 event but SCG addition fails. The next NR segment number may be selected, and NR measurement may be performed again on the target NR cell until SCG is successfully added or all NR segment numbers fail to be added, and then NR measurement is ended.

In this embodiment, NR measurement is performed by using NR frequency band numbers that can be supported by a terminal device as frequency bands for NR measurement in a target NR cell, so that the number of measurable NR frequency bands is greater, the application range is greater, and the compatibility is better.

Mode III

In the third mode, the first endec information may be the endec information in the EDNC list that requests to inquire the terminal device capability, which is transmitted when the base station inquires the terminal device capability. For example only and not by way of limitation, referring to fig. 2, the terminal device capability query command (UE CAP query) sent by the eNB includes an endec list requesting query, such as whether the terminal device supports B20+ n78, B20+ n77, and B18+ n77, then B20+ n78, B20+ n77, and B18+ n77 may be used as the endec list of the eNB. Then, the NR frequency bands corresponding to n77 and n78 are respectively used as the frequency bands when NR measurement is performed by the target NR cell.

In this embodiment, the endec included in the terminal device capability query request transmitted by the base station is an endec that the base station can support. Therefore, the NR frequency band number in the ENDC list is used as the frequency band when the target NR cell carries out NR measurement, the NR measurement can be carried out more specifically, and the measurement failure caused by the compatibility problem is reduced.

Mode IV

In the fourth manner, the first endec information may be determined according to endec information that will successfully access the target NR cell. Referring to fig. 5, the terminal device acquiring the first endec information may include:

and S114, acquiring an ENDC history registration list of the terminal equipment.

Wherein the ENDC history registration list includes ENDC information of at least one successfully accessed NR cell.

In some embodiments, the endec information for successful access to an NR cell may be stored in a history registration list after each successful addition of an SCG. The historical registration list may be stored through Public Land Mobile Network (PLMN) dimension, and the endec information in the historical registration list is the endec information that is supported by the NR cell and that has been successfully accessed. The NR frequency band corresponding to n77 is taken as the frequency band when NR measurement is performed by the target NR cell.

And S125, taking the ENDC information in the history registration list as first ENDC information.

By way of example only, and not limitation, if ENDC information for B20+ n77 is included in the history registration list, the ENDC information may be taken as the first ENDC information.

In this embodiment, the endec that successfully accesses the cell each time is saved, and the NR band number corresponding to the saved endec is measured at the time of the next access. Since the stored ENDC information is successfully accessed ENDC information, the NR measurement is carried out on the target NR cell by using the NR frequency band corresponding to the stored ENDC information, the probability of successful measurement can be effectively improved, and the measurement failure caused by compatibility is reduced.

and S13, if the result of the NR measurement meets the B1 event, accessing the terminal equipment to a target NR cell meeting the B1 event.

In some embodiments, referring to the example of fig. 1, there may be multiple base stations at the time of NR measurement. The terminal device performs NR measurement on each target NR cell within the signal range, and obtains NR measurement results of a plurality of target NR cells. Wherein the NR measurement result is used to indicate the quality of a target NR cell where the NR measurement is performed. For example, the terminal device continuously measures at least one NR frequency band of the target NR cell for a certain period of time, and averages a plurality of measurement results (power values) obtained to obtain an average power value. The average power value may represent the quality of the target NR cell.

Wherein, the threshold value of the B1 event is also a power value. And if the average value of the power of the quality of the target NR cell subjected to NR measurement in the preset time is greater than the threshold value of the B1 event, determining that the measurement result of the NR cell meets the B1 event. For example, the threshold value for a B1 event may be set to-100 dbm. And if the power value of the target NR cell for carrying out the NR measurement is larger than-100 dbm on average in 5 seconds, determining that the measurement result of the NR cell meets the B1 event.

It should be noted that, a Cell meeting the B1 event may be added as an SCG of the terminal device, and then the current LTE Cell is a Master Cell Group (MCG), and the MCG and the SCG are networked together, so as to implement dual link of different systems.

In some embodiments, if the SCG addition is successful, the information of the endics to which the SCG is successfully added is stored in the history registration list in S127, and the endics in the history registration list can be used as the endics when the NR measurement is performed on the target NR cell next time.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
