In an MR-DC scenario, the first network device 102 may be a master network device; the second network device 103 may be a secondary network device.

In addition, the terminal device may also be a terminal device in an internet of things (IoT) system.

For the purpose of facilitating understanding of the embodiments of the present application, the following description will first explain the concepts related to the present embodiments.
1. Radio Resource Management (RRM) measurements
RRM measurement refers to having a UE monitor the communication quality of its serving cell and/or neighboring cells (i.e., non-serving cells) in real time. Thus, the mobility management may change the serving cell of the UE through handover or cell selection/reselection when the serving cell signal quality of the UE degrades to a certain degree based on the measurement result of the RRM measurement, that is, select a neighboring cell with better communication quality as a new serving cell of the UE, so as to ensure that a communication link between the network and the UE is not interrupted due to the movement of the UE.
When the UE is in the RRC connected state, the network may configure the UE to perform measurements according to the measurement configuration and report the measurement results. Specifically, the measurement process in the connected state mainly includes three steps of measurement configuration, measurement execution, and measurement reporting.
The measurement configuration refers to that a network device (e.g., a base station) provides measurement configuration (measurement configuration) to a UE through RRC dedicated signaling (dedicated signaling). For example, the measurement configuration is issued by an RRC Reconfiguration message (RRC Reconfiguration message) or an RRC recovery message (RRC Resume message). The measurement configuration may include:
a) Measurement object (measurement object): the UE executes a measurement object, and specifically indicates the frequency point related information needing to be measured in the application;
b) Measurement object (measurement object): the UE executes a measurement object, and specifically indicates the frequency point related information needing to be measured in the application;
c) Measurement identities (measurement identities): a measurement identity is used to associate a measurement object with a reporting configuration, i.e. a measurement identity label (a measurement object plus a reporting configuration) is used to identify a measurement. The UE will include the corresponding measurement mark in the reported measurement report as a reference for the network, so that the network can distinguish which measurement result is;
d) Measurement interval (measurement gap): the UE may be configured with a time period for performing the measurements. During the measurement interval, the UE performs measurements on the target measurement object without the need for transceiving data and/or other signals. The measurement may or may not require a measurement interval depending on the capability of the UE, the configuration of the UE, the frequency on which the UE is currently operating, etc.
Measurement intervals can be divided into two broad categories: (1) per-UE class interval (per-UE gap); (2) the class interval per Frequency Range (per-FR) gap may be further subdivided into per FR1 gap and per FR2 gap according to FR. Wherein, the two types of gap, the per-UE gap and the per-FR gap, can only configure one of them for the UE, for example, if the network device configures the per-UE gap for the UE, the per-FR gap can not be configured for the UE; the network device may configure per-FR1 gap and/or per-FR2 gap for the UE without configuring the UE with per-UE gap.
e) Measurement quantity configuration (quality configuration): measurement filtering configuration, i.e. filter coefficient configuration used when the UE filters the measurement results.
2. NR RRM measurement
In 5G NR, a measurement object includes frequency point reference signal (reference signal) arrangement information to be measured. There are two types of NR reference signals: a synchronization signal/physical broadcast channel Block (SS/PBCH Block, SSB) and a channel state information-reference signal (CSI-RS).
The measurement may be classified into intra-frequency measurement (intra-frequency measurement), inter-frequency measurement (inter-frequency measurement), and inter-system measurement (inter-RAT measurement). Inter-system measurement refers to measurement for systems other than NR (e.g., measurement for 2G/3G/4G system, etc.). Intra-frequency measurements and measurements are intra-RAT measurements, and according to the type of NR reference signal, there are SSB-based measurements and CSI-RS-based measurements.
For measurement based on SSB, if the SSB center frequency of a certain measurement frequency point is the same as the SSB center frequency of a serving cell and the sub-carrier space (SCS) of the SSB of the certain measurement frequency point and the SSB of the serving cell are also the same, the frequency point measurement is the same-frequency measurement; otherwise, if the center frequencies of the two SSBs are different from the subcarrier spacing of the SSBs, the frequency point measurement is measurement.
For measurement based on CSI-RS, if the CSI-RS center frequency of a certain measurement frequency point is the same as the CSI-RS center frequency of a serving cell, and the subcarrier spacing and Cyclic Prefix (CP) types of the CSI-RS of the certain measurement frequency point and the serving cell are also the same, the frequency point measurement is the same-frequency measurement; otherwise, if the center frequencies of the two CSI-RSs, the subcarrier intervals of the CSI-RSs and the type of the cyclic prefix are different, the frequency point measurement is measurement.
3. Bandwidth part (BWP)
The bandwidth of a 5G NR system can reach 400MHz at maximum. If all UEs are required to support the maximum 400MHz, higher requirements are imposed on the performance of the UEs, which is not beneficial to reducing the cost of the UEs. Meanwhile, a large bandwidth means a high sampling rate, and a high sampling rate means high power consumption, but actually one UE cannot occupy the whole 400MHz bandwidth at the same time, and if the UE also adopts a sampling rate corresponding to the 400MHz bandwidth, it is a waste of performance.
Therefore, an adaptive Bandwidth (BA) technique is introduced into the 5G NR. With this technique, the reception and transmission bandwidth of the UE need not be as large as the bandwidth of its serving cell and can be adjusted, including: (1) the bandwidth width may be changed (e.g., to shrink the bandwidth during periods of low activity to save power); (2) the position (i.e., the center frequency point of the bandwidth part BWP) can be moved in the frequency domain (e.g., to increase scheduling flexibility); (3) the subcarrier spacing configuration may be changed (e.g., to accommodate different services). I.e., a subset of the total bandwidth of the serving cell, is referred to as the bandwidth fraction, BA may be achieved by providing the UE with BWP configuration and informing the UE which configured BWP is the currently active BWP.
In the prior art, a network may configure multiple BWPs for a serving cell, but only activate one BWP at the same time on the serving cell, i.e. active BWP (active BWP) refers to the BWP currently being used by the UE. Different BWPs may be activated simultaneously on different serving cells.
The active BWP may be an initial BWP (initial BWP), a default BWP (default BWP), or other BWP configured over the network. The initial BWP is a BWP used by the UE for initial access on the serving cell. The default BWP is a smaller bandwidth BWP for the network configuration. Typically, the bandwidth of the initial BWP and the default BWP will be relatively small, while the active BWP other than the initial/default BWP is a BWP with a larger bandwidth for data transmission.
4. NR Pilot frequency without interval measurement (inter-frequency measurements with gap)
In the standard protocol of the initial release of 5G NR, for NR measurement, the UE must require a measurement interval to perform the measurement. Subsequently, in the standard protocol of the subsequent version, the SSB-based NR measurement is enhanced, specifically, when the target pilot frequency point SSB to be measured completely falls within the active BWP (on any serving cell) of the UE, the UE may no longer need to perform measurement on the target pilot frequency point with a measurement interval, and the enhancement is referred to as an NR pilot frequency non-interval measurement characteristic.
For example, assume that the UE currently has BWP1 as the active BWP on serving cell 1 and BWP2 as the active BWP on serving cell 2. And the SSB1 and the SSB2 are two pilot frequency points to be detected. SSB1 completely falls on the activated BWP1 of the UE, therefore, the UE can carry out pilot frequency non-interval measurement on the SSB1 frequency point; and the SSB2 does not fall on any active BWP of the UE, therefore, the UE does not carry out pilot frequency non-interval measurement on the SSB2 frequency point.
It should be understood that the technical solutions in the present application are not limited to SSB-based measurements, but are equally applicable when CSI-RS-based measurements are possible as well as other types of measurements, such as inter-system measurements.
5. Carrier Aggregation (CA)
Carrier aggregation CA is a technique for increasing transmission bandwidth to meet the requirements of single-user peak rate and system capacity improvement. The CA technology can aggregate 2 or more component carriers CC in one base station, thereby realizing a larger transmission bandwidth and effectively improving the uplink and downlink transmission rate. The UE determines that at most several carriers can be simultaneously used for uplink and downlink transmission according to the capacity of the UE. CA mainly comprises three types: intra-band aggregation of contiguous CCs, intra-band aggregation of non-contiguous CCs, and inter-band aggregation.
6. Measurement in advance (early measurement)
The establishment of the dual connectivity/carrier aggregation DC/CA configuration depends on the measurement report of the terminal device on the surrounding neighboring cells, so that the network determines a suitable secondary cell. In a conventional mechanism, after a terminal device enters an RRC connected state, a network may configure the terminal device to perform measurement reporting on a neighboring cell, and the terminal device generally needs a certain time to perform measurement reporting, which causes a certain time delay for CA/DC establishment.
In order to enable the terminal device to quickly establish a suitable CA/DC when entering the RRC connected state, an advanced measurement technique is introduced. Specifically, the network may provide a measurement configuration in advance when releasing the terminal device to an RRC IDLE state (RRC _ IDLE) or an RRC INACTIVE state (RRC _ INACTIVE), so that the terminal device may measure the candidate frequency points of the CA/DC in advance and obtain and record a measurement result when the terminal device is in the RRC IDLE state or the RRC INACTIVE state. Subsequently, when the terminal device re-enters the connected state, the network can request the result of the advance measurement from the terminal device, and the terminal device sends the advance measurement report to the network, so that the network can determine the CA/DC configuration provided for the terminal device as soon as possible.
Fig. 2 is a schematic diagram of an LTE system architecture suitable for the embodiment of the present application.
In the application scenario in fig. 2, the base station eNB/en-gNB of the serving cell of the UE is responsible for providing the UE with the user plane and control plane protocol functions of the E-UTRA of the 4G radio access network. The Mobility Management Entity (MME) has functions of sending a paging message to a corresponding eNB, mobility control in an idle state, encryption and integrity protection of non-access stratum signaling, and the like. Serving Gateways (SGWs) support user plane data exchange for UE mobility, etc. The S1 interface is positioned between the eNB and the MME/SGW, and connects the eNB with the MME to mainly complete the functions of radio access bearer control, interface-dedicated operation and maintenance and the like of the S1 interface. The eNBs are connected with each other through an X2 interface to form a Mesh type network.
The LTE base station eNB serves as a Master Node (MN), and the NR base station gNB serves as a Secondary Node (SN). An S1 interface exists between an LTE eNB and an Evolved Packet Core (EPC) of an LTE system, and there is at least Control plane connection (S1-Control, S1-C) and also user plane connection (S1-user plane, S1-U). There is an S1-U interface between the NR gbb and the EPC, i.e. only a user plane connection is possible.
When the embodiment of the present application is applied to an LTE system, on one hand, the eNB/en-gNB may send an RRC message to the UE, where the RRC message may include, for example, measurement configuration. And the UE completes corresponding operation according to the indication of the RRC message and reports related information (such as a measurement report) to the eNB/en-gNB according to the situation. On the other hand, the eNB and the en-gNB can also interact, and the eNB or the en-gNB determines the RRC message sent to the UE according to the received information.
Fig. 3 is a schematic diagram of a 5G system architecture suitable for use in embodiments of the present application.
The gNB in fig. 3 is a node providing NR user plane and control plane protocol terminals to the UE and is connected to a 5GC (5G core network) via an NG interface, and the NG-eNB provides evolved universal terrestrial radio access network (E-UTRA) user plane and control plane protocol terminals to the UE and is connected to the 5GC via the NG interface. The access and mobility management function (AMF) is responsible for functions of encryption and security of NAS messages, registration, access, mobility, authentication, short message passing through, and the like, and can be similar to the MME entity of 4G. The User Plane Function (UPF) is used as an interface with a data network to complete functions of user plane data forwarding, session/stream level-based charging statistics, bandwidth limitation, and the like. I.e. packet routing and forwarding, quality of service (QoS) handling of user plane data, etc. The gNBs are connected with each other through an Xn interface.
When the embodiment of the present application is applied to a 5G system, on one hand, the gNB/ng-eNB may send an RRC message to the UE, where the RRC message may include, for example, measurement configuration. And the UE completes corresponding operation according to the indication of the RRC message and reports related information (such as a measurement report) to the gNB/ng-eNB according to the situation. On the other hand, the gNB and the ng-eNB can interact, and the gNB or the ng-eNB determines the RRC message sent to the UE according to the received information.
Fig. 4 is a schematic diagram of a CA scenario applicable to an embodiment of the present application.
The cells may be divided into primary and secondary cells in a CA scenario. The primary cell PCell is a cell in which the terminal device performs initial connection establishment, or performs RRC connection reestablishment, or is a primary cell designated in a handover process. The PCell is responsible for RRC communication with the terminal device. A CC corresponding to the PCell is referred to as a Primary Component Carrier (PCC). The secondary cell SCell is added through RRC connection reconfiguration after an initial security activation procedure for providing additional radio resources. The CC corresponding to the SCell is referred to as SCC.
A UE configured with CA may be connected to 1 PCell and up to 31 scells, which form a serving cell set of the UE, the serving cell set containing up to 32 serving cells (i.e., 1 PCell and up to 31 scells). CA is a UE-level property, and different UEs may have different pcells, scells, and serving cell sets. The same cell may be a PCell for a certain UE, but an SCell for another UE.
The UE performs an initial connection establishment process or a connection reestablishment process in the primary cell. The primary cell is indicated as primary cell during handover. RRC connection establishment, the secondary cell may be configured to provide additional radio resources.
Fig. 5 is a schematic diagram of an MR-DC scenario suitable for use in embodiments of the present application.
As shown in fig. 5, the MN base station manages several cells (cells marked by solid line borders in fig. 5), one of which serves as the primary cell PCell of the UE, and several of the remaining cells may serve as scells of the UE. Each serving cell of the UE under the MN is called a Master Cell Group (MCG), where a master cell PCell is a cell used for initiating initial access by the UE in the MCG.
Similarly, several cells (cells marked by dashed borders in fig. 5) are also managed under the SN base station, where one cell serves as the primary and secondary cell PSCell of the UE, and several of the remaining cells may serve as scells of the UE. Each serving cell of the UE under the SN is called a Secondary Cell Group (SCG), where the primary secondary cell PSCell is a cell used for the UE to initiate initial random access in the SCG.
According to the type of MN base station, the type of SN base station, and the type of core network to which the base station is connected, MR-DC can be divided into various types, and the specific types are as follows:
(1) When MN and SN base station are connected to core network of LTE (i.e. E-UTRA), if MN is LTE base station eNB and SN is NR base station gNB, then MR-DC at this time is called EN-DC (E-UTRA-NR DC).
(2) When MN and SN base stations are connected to the core network of the 5G NR:
a) If the MN is an LTE base station eNB and the SN is an NR base station gNB, the MR-DC at the moment is called NGEN-DC (NG-RAN E-UTRA-NR DC);
b) If the MN is an NR base station gNB and the SN is an LTE base station eNB, the MR-DC at the moment is called NE-DC (NR-E-UTRA DC);
c) If both MN and SN are NR base stations gNB, the MR-DC at this time is called NR-DC (NR-NR DC).
Under all the MR-DC scenarios described above, the MN and the SN can independently configure measurements for the UE, i.e. both the MN and the SN can send measurement configurations to the UE, and the UE independently maintains the measurements configured by the base stations on both sides.
Fig. 6 is an exemplary information interaction diagram of the measurement configuration method according to the present application.
At S610, network device 102 (which may also be referred to as a first network device) receives information of inter-frequency non-interval measurement from network device 103 (which may also be referred to as a second network device).
In one possible implementation, network device 102 may be a MN and network device 103 may be a SN.
According to the difference of the types of the information measured by the pilot frequency without interval, the step can be divided into three modes:
mode 1
In particular, the request information may be used to request enablement/configuration from network device 102: (enable/configure) The function of inter-frequency gapless measurement of the terminal device, or for requesting de-enabling/de-configuration from the network device 102 (disable/de-configure) The function of inter-frequency non-interval measurement of the terminal device may also be used to request the network device 102 for a function of inter-frequency non-interval measurement of a non-enabled/non-configured (non-to-enabled/configurable) terminal device.
Mode 2
Specifically, the indication information may be used to indicate to the network device 102 that the pilot frequency points that can be measured by the terminal device at different intervals exist in the pilot frequency points to be measured that are configured by the network device 103 for the terminal device, or indicate to the network device 102 that the pilot frequency points that can be measured by the terminal device at different intervals do not exist in the pilot frequency points to be measured that are configured by the network device 103 for the terminal device.
Mode 3
The network device 102 receives the pilot frequency point information from the network device 103.
Specifically, the pilot frequency point information is used to indicate to the network device 102 which pilot frequency point terminal device/terminal devices can perform non-interval measurement. In this manner, the network device 102 receives the pilot frequency point information that is indicated by the network device 103 and that is specifically available for the terminal device to measure pilot frequency without interval, and further, may determine whether the frequency point available for the terminal device to measure without interval is always available for measurement without interval or available for measurement without interval according to the indication information. The pilot frequency point information may include an Absolute Radio Frequency Channel Number (ARFCN) of the pilot frequency point.
For example, the network device 103 may indicate to the network device 102 whether the pilot frequency point is satisfied to stay completely within the terminal device active BWP, i.e., whether the UE can always fall within the UE active BWP regardless of which BWP/BWPs the UE activates, or may not fall within the UE active BWP depending on the case of the UE active BWP.
At S620, the network device 102 (which may also be referred to as a first network device) sends indication information to the terminal device.
According to the difference that the indication information specifically includes information, the step can be divided into three modes:
mode A
The network device 102 sends indication information to the terminal device 104, wherein the indication information comprises first information, and the first information comprises an enabling indication of inter-frequency gapless measurement.
The enable indication of inter-frequency non-interval measurement included in the first information may be used to indicate that the function of inter-frequency non-interval measurement of the terminal device 104 is enabled, or may be used to indicate that the function of inter-frequency non-interval measurement of the terminal device 104 is disabled, and may also be used to indicate that the function of inter-frequency non-interval measurement of the terminal device is not enabled.
Specifically, the network device 102 may determine how to control the inter-frequency non-interval measurement function based on the inter-frequency point to be measured and the BWP configuration of the terminal device 104. For example, if iso-frequency bin 1 may fall within terminal device 104 active BWP, network device 102 may enable the inter-frequency non-interval measurement function. The network device 102 may also determine how to control the inter-frequency non-interval measurement function based on the measurement time conditions of the measurement interval and the inter-frequency point to be measured. For example, the measurement occasion of the inter-frequency bin 2 is completely covered by the measurement interval, and the network device 102 may not enable/disable the inter-frequency non-interval measurement function.
Mode B
The network device 102 sends indication information to the terminal device 104, where the indication information includes second information, and the second information includes measurement interval configuration information, and the measurement interval configuration information is used to indicate a time interval during which the terminal device 104 is capable of performing measurement.
For example, the network device 103 indicates to the network device 102 that the pilot frequency point 1 is a frequency point that the terminal device 104 can measure without interval, and the network device 102 may determine, when sending measurement interval configuration information to the terminal device 104, a measurement timing at which the measurement interval does not cover or partially covers the pilot frequency point 1, where the measurement timing may include a measurement time window (reference signal measurement timing configuration) of a reference signal, for example, a measurement time window of the SSB/CSI-RS.
For another example, if the network device 103 indicates to the network device 102 that the pilot frequency point 1 is a frequency point that the terminal device 104 can always satisfy non-interval measurement, and the pilot frequency point 2 is a frequency point that the terminal device can measure without intervals under certain conditions, the network device 102 may determine a measurement time when the measurement interval does not cover the pilot frequency point 1 and a measurement time when part of the measurement interval covers the pilot frequency point 2 when sending measurement interval configuration information to the terminal device 104.
Mode C
The network device 102 sends indication information to the terminal device 104, where the indication information includes first information and second information, the first information includes an enable indication of inter-frequency gapless measurement, and the second information includes measurement gap configuration information, and the measurement gap configuration information is used for indicating a time gap during which the terminal device 104 can perform measurement. The first information and the second information may be carried in the same message, for example, a radio resource control RRC message, and are simultaneously sent to the terminal device 104; or may be carried in different messages and sent to the terminal device 104, respectively.
As described in manner B, the network device 102 may determine the measurement interval configuration provided for the terminal device based on the inter-frequency gapless measurement information provided by the network device 103; meanwhile, as described in the manner a, the network device 102 may determine how to control the inter-frequency non-interval measurement function according to the frequency point to be measured and the BWP configuration condition of the terminal device.
According to the technical scheme of the application, the second network equipment provides the pilot frequency gapless measurement information for the first network equipment, so that the first network equipment can more reasonably determine whether the terminal equipment is configured to use the pilot frequency gapless measurement function, and provides the terminal equipment with the measurement gap configuration matched with the pilot frequency gapless measurement function.
Currently, in an NR-DC scenario, the prior art provides that a primary base station can configure a terminal device with a measurement interval, while a secondary base station cannot configure a terminal device with a measurement interval. In addition, since the main base station and the secondary base station are NR base stations, the current standard does not know whether both the main base station and the secondary base station can control the inter-frequency non-interval measurement function and how the main base station and the secondary base station control/simultaneously control the inter-frequency non-interval measurement function, so that the terminal device may not know whether the inter-frequency non-interval measurement function should be used and how the inter-frequency non-interval measurement function should be used.
In view of the above problem, the present application proposes two possible control manners, that is, only allowing the network device 102 (which may also be referred to as a first network device) to control whether the terminal device 104 uses the inter-frequency gapless measurement function, or allowing the network device 102 and the network device 103 to control whether the terminal device 104 uses the inter-frequency gapless measurement function.
The above two control modes will be described in detail with reference to fig. 7 and 8.
Fig. 7 is another example information interaction diagram of the measurement configuration method of the present application. In the method shown in fig. 7, only the network device 102 (which may also be referred to as a first network device) is allowed to control whether the terminal device 104 uses the inter-frequency gapless measurement function.
At S710, the network device 103 (which may also be referred to as a second network device) determines information of inter-frequency non-interval measurement.
The specific manner in which the network device 103 determines the inter-frequency measurement-without-interval information is not limited in this application.
At S720, the network device 102 receives information of inter-frequency non-interval measurement from the network device 103. The step is the same as step S610 described in fig. 6, and the detailed information refers to the description in step S610, which is not repeated herein.
At S730, the network device 102 determines indication information according to the inter-frequency non-interval measurement information.
The indication information may include first information and/or second information, where the first information may include an enable indication of inter-frequency gapless measurement, and the second information may include measurement interval configuration information, where the measurement interval configuration information may be used to indicate a time interval in which the terminal device 104 is capable of performing measurement. The first information and the second information may be carried in the same message, for example, a radio resource control RRC message, and are simultaneously sent to the terminal device 104; or may be carried in different messages and sent to the terminal device 104..
Specifically, the network device 102 may determine the enabling indication of the inter-frequency non-interval measurement according to the information of the inter-frequency non-interval measurement provided by the network device 103. For example, the above-mentioned information of inter-frequency non-interval measurement is request information of the request enabling terminal device 104 sent by the network device 103, and the network device 102 may determine to enable the inter-frequency non-interval measurement function. For another example, the above information of inter-frequency non-interval measurement is request information of the request enabling terminal device 104 transmitted by the network device 103, and the network device 102 may also determine not to enable/disable the inter-frequency non-interval measurement function.
After determining the indication information, the network device 102 transmits the indication information to the terminal device 104 at S740. This step is the same as step S620 described in fig. 6, and please refer to the description of step S620 for details, which are not described herein again.
After receiving the indication information, the terminal device 104 may perform step S750, and perform measurement according to the indication information.
Specifically, the terminal device 104 may enable/disable the inter-frequency measurement-free function according to the enable indication of the inter-frequency measurement-free in the indication information, and the terminal device 104 may also perform measurement according to the measurement interval configuration information in the indication information.
According to the technical scheme of the application, the second network equipment provides pilot frequency non-interval measurement information for the first network equipment, and only allows the first network equipment to control whether the terminal equipment uses the pilot frequency non-interval measurement function, so that the first network equipment can more reasonably determine whether the terminal equipment is configured to use the pilot frequency non-interval measurement function, and provides measurement interval configuration matched with the pilot frequency non-interval measurement function for the terminal equipment.
Fig. 8 is a schematic diagram of information interaction of another example of the measurement configuration method of the present application. In the method shown in fig. 8, network device 102 (which may also be referred to as a first network device) and network device 103 (which may also be referred to as a second network device) are allowed to control whether end device 104 uses the inter-frequency gapless measurement function.
Steps S810 and S820 are the same as steps S710 and S720 shown in fig. 7, and please refer to the description of steps S710 and S720 for details, which are not repeated herein.
In the present application, the network device 102 and the network device 103 control whether the terminal device 104 uses the inter-frequency gapless measurement function may be divided into three cases, which will be described in detail with reference to the drawings.
Case 1
The network device 102 and the network device 103 independently control the function of non-interval measurement of pilot frequency, that is, the network device 102 only controls whether the terminal device of pilot frequency configured by the network device 102 can perform non-interval measurement, and the network device 103 only controls whether the terminal device of pilot frequency configured by the network device 103 can perform non-interval measurement.
In step S830, the network device 102 determines indication information (for the sake of distinction, we may refer to it as first indication information) according to the information of the inter-frequency non-interval measurement. The indication information may include first information and/or second information, the first information may include an enable indication of inter-frequency gapless measurement, and the second information may include measurement interval configuration information, which may be used to indicate a time interval during which the terminal device 104 is capable of performing measurement. The first information and the second information may be carried in the same message, for example, a radio resource control RRC message, and are simultaneously sent to the terminal device 104; or may be carried in different messages and sent to the terminal device 104, respectively.
Specifically, the network device 102 may determine how to control the inter-frequency non-interval measurement function, i.e., determine an enable indication of the inter-frequency non-interval measurement, based on the BWP configuration situation of the inter-frequency point to be measured configured by the network device 102 and the terminal device 104, and/or the measurement opportunity situation of the measurement interval and the inter-frequency point to be measured configured by the network device 102, where the measurement opportunity may include a measurement time window of a reference signal, for example, a measurement time window of an SSB/CSI-RS. For example, if pilot frequency bin 1 may fall within BWP enabled by terminal device 104, then network device 102 may enable the pilot frequency gapless measurement function. For another example, if the measurement timing of the inter-frequency bin 2 is completely covered by the measurement interval, the network device 102 may not enable/disable the inter-frequency non-interval measurement function.
Correspondingly, in step S831, the network device 103 determines indication information (for the sake of distinction, we may refer to it as second indication information) from the information of the inter-frequency non-interval measurement. The indication information may include first information and/or second information, the first information may include an enable indication of inter-frequency gapless measurement, and the second information may include measurement interval configuration information, which may be used to indicate a time interval during which the terminal device 104 is capable of performing measurement.
Specifically, the network device 103 may determine how to control the inter-frequency non-interval measurement function, that is, determine the enabling indication of the inter-frequency non-interval measurement, based on the BWP configuration condition of the inter-frequency point to be measured configured by the network device 103 and the terminal device 104, and/or the measurement timing condition of the measurement interval and the inter-frequency point to be measured configured by the network device 103. For example, if inter-frequency bin 1 may fall within BWP enabled by terminal device 104, then network device 103 may enable the inter-frequency non-interval measurement function. For another example, if the measurement timing of the inter-frequency bin 2 is completely covered by the measurement interval, the network device 103 may not enable/disable the inter-frequency non-interval measurement function.
In S840 and S841, the network device 102 and the network device 103 transmit the above-described instruction information to the terminal device 104, respectively. The indication information, i.e. the first information and the second information, may be carried in a radio resource control RRC message.
After receiving the indication information, the terminal device 104 performs step S850 to perform measurement according to the indication information.
Specifically, the terminal device 104 may enable/disable the inter-frequency non-interval measurement function according to an enable indication of the inter-frequency non-interval measurement in the indication information, and the terminal device 104 may further measure the corresponding frequency point to be measured according to the measurement interval configuration information in the indication information.
Case 2
Both the network device 102 and the network device 103 may control the pilot frequency non-interval measurement function, and more specifically, the network device 102 and the network device 103 may control whether the pilot frequency point terminal devices configured by the network device 102 and the network device 103 may perform non-interval measurement, and as long as at least one of the network device 102 and the network device 103 enables the pilot frequency non-interval measurement function, the terminal device may use the pilot frequency non-interval measurement.
In step S830, the network device 102 determines indication information (for the sake of distinction, we may refer to it as first indication information) according to the information of the inter-frequency non-interval measurement. The indication information may include first information and/or second information, the first information may include an enable indication of inter-frequency gapless measurement, and the second information may include measurement interval configuration information, which may be used to indicate a time interval during which the terminal device 104 is capable of performing measurement. The first information and the second information may be carried in the same message, for example, a radio resource control RRC message, and are simultaneously sent to the terminal device 104; or may be carried in different messages and sent to the terminal device 104.
Specifically, the network device 102 may determine how to control the inter-frequency non-interval measurement function, that is, determine an enabling indication of the inter-frequency non-interval measurement, based on BWP configuration conditions of the inter-frequency point to be measured and the terminal device 104 configured by the network device 102 and the network device 103 and/or measurement timing conditions of the measurement interval and the inter-frequency point to be measured configured by the network device 102 and the network device 103. For example, if iso-frequency bin 1 may fall within BWP enabled by terminal device 104, then network device 102 may enable the inter-frequency non-interval measurement function. For another example, if the measurement timing of the inter-frequency bin 2 is completely covered by the measurement interval, the network device 102 may not enable/disable the inter-frequency non-interval measurement function.
Correspondingly, in step S831, the network device 103 determines indication information (for the sake of distinction, we may refer to it as second indication information) from the information of the inter-frequency non-interval measurement. The indication information may include first information and/or second information, the first information may include an enable indication of inter-frequency gapless measurement, and the second information may include measurement interval configuration information, which may be used to indicate a time interval during which the terminal device 104 is capable of performing measurement.
Specifically, the network device 103 may determine how to control the inter-frequency non-interval measurement function, that is, determine an enabling indication of the inter-frequency non-interval measurement, based on BWP configuration conditions of the inter-frequency point to be measured and the terminal device 104 configured by the network device 102 and the network device 103 and/or measurement timing conditions of the measurement interval and the inter-frequency point to be measured configured by the network device 102 and the network device 103. For example, if iso-frequency bin 1 may fall within BWP enabled by terminal device 104, then network device 102 may enable the inter-frequency non-interval measurement function. For another example, if the measurement timing of the inter-frequency bin 2 is completely covered by the measurement interval, the network device 102 may not enable/disable the inter-frequency non-interval measurement function.
In S840 and S841, the network device 102 and the network device 103 transmit the above-described instruction information to the terminal device 104, respectively. The indication information, i.e. the first information and the second information, may be carried in a radio resource control RRC message.
After receiving the indication information, the terminal device 104 performs step S850 to perform measurement according to the indication information.
Specifically, the terminal device 104 may enable/disable the inter-frequency non-interval measurement function according to the enable indication of the inter-frequency non-interval measurement in the indication information, in which case, the terminal device 104 may enable the inter-frequency non-interval measurement function only if one of the enable indications of the inter-frequency non-interval measurement from the network device 102 and the network device 103 indicates that the inter-frequency non-interval measurement function is enabled. The terminal device 104 may also measure the corresponding frequency point to be measured according to the measurement interval configuration information in the indication information.
Case 3
Both the network device 102 and the network device 103 may control the function of inter-frequency non-interval measurement, and more specifically, the network device 102 may control whether inter-frequency point terminal devices configured by the network device 102 and the network device 103 may perform non-interval measurement, and the network device 103 only controls whether inter-frequency point terminal devices configured by the network device 103 may perform non-interval measurement.
In step S830, the network device 102 determines indication information (for the sake of distinction, we may refer to it as first indication information) according to the information of the inter-frequency non-interval measurement. The indication information may include first information and/or second information, the first information may include an enable indication of inter-frequency gapless measurement, and the second information may include measurement interval configuration information, which may be used to indicate a time interval during which the terminal device 104 is capable of performing measurement.
Specifically, the network device 102 may determine how to control the inter-frequency gapless measurement function, that is, determine an enabling indication of the inter-frequency gapless measurement, based on BWP configuration situations of the inter-frequency point to be measured and the terminal device 104 configured by the network device 102 and the network device 103 and/or measurement timing situations of the inter-frequency point to be measured configured by the network device 102 and the network device 103. For example, if pilot frequency bin 1 may fall within BWP enabled by terminal device 104, then network device 102 may enable the pilot frequency gapless measurement function. For another example, if the measurement timing of the inter-frequency bin 2 is completely covered by the measurement interval, the network device 102 may not enable/disable the inter-frequency non-interval measurement function.
Correspondingly, in step S831, the network device 103 determines indication information (which we may call as second indication information for ease of distinction) from the information of the inter-frequency gapless measurement. The indication information may include first information and/or second information, the first information may include an enable indication of inter-frequency gapless measurement, and the second information may include measurement interval configuration information, which may be used to indicate a time interval during which the terminal device 104 is capable of performing measurement.
Specifically, the network device 103 may determine how to control the inter-frequency non-interval measurement function, that is, determine the enabling indication of the inter-frequency non-interval measurement, based on the BWP configuration condition of the inter-frequency point to be measured configured by the network device 103 and the terminal device 104, and/or the measurement timing condition of the measurement interval and the inter-frequency point to be measured configured by the network device 103. For example, if inter-frequency bin 1 may fall within BWP enabled by terminal device 104, then network device 103 may enable the inter-frequency non-interval measurement function. For another example, if the measurement timing of the inter-frequency bin 2 is completely covered by the measurement interval, the network device 103 may not enable/disable the inter-frequency non-interval measurement function.
In S840 and S841, the network device 102 and the network device 103 respectively transmit the above-described instruction information to the terminal device 104. The indication information, i.e. the first information and the second information, may be carried in a radio resource control RRC message.
After receiving the indication information, the terminal device 104 performs step S850 to perform measurement according to the indication information.
Specifically, the terminal device 104 may enable/disable the inter-frequency non-interval measurement function according to an enable indication of the inter-frequency non-interval measurement in the indication information, and the terminal device 104 may further measure the corresponding frequency point to be measured according to the measurement interval configuration information in the indication information.
It should be understood that, in this case, since the network device 102 may control whether the inter-frequency point terminal device 104 configured by the network device 102 and the network device 103 may measure without interval, and the network device 103 only controls whether the inter-frequency point terminal device 104 configured by the network device 103 may measure without interval, it may happen that the network device 102 and the network device 103 give different enabling indications for the same inter-frequency point configured by the network device 103. For example, for pilot frequency point 1 configured by network device 103, network device 102 instructs terminal device 104 to enable the pilot frequency non-interval measurement function, and network device 103 instructs terminal device 104 not to enable the pilot frequency non-interval measurement function. In this case, when the enable indications of the network device 102 (which may also be referred to as a first network device) and the network device 103 (which may also be referred to as a second network device) conflict, it may be specified that the terminal device 104 preferentially performs corresponding operations according to the indication of the network device 102, it may be specified that the terminal device 104 preferentially performs corresponding operations according to the indication of the network device 103, and it may be also specified that the terminal device 104 enables inter-frequency non-interval measurement as long as there is an indication to enable the inter-frequency non-interval measurement function in the enable indications of the network device 102 and the network device 103, like the control manner in the above case 2.
According to the technical scheme of the application, the second network equipment provides pilot frequency non-interval measurement information for the first network equipment, and allows the first network equipment and the second network equipment to control whether the terminal equipment uses the pilot frequency non-interval measurement function, so that the first network equipment and the second network equipment can more reasonably determine whether the terminal equipment is configured to use the pilot frequency non-interval measurement function, and provide measurement interval configuration matched with the pilot frequency non-interval measurement function for the terminal equipment.
Fig. 9 is a schematic diagram illustrating an example of information interaction in the measurement method of the present application.
At S910, the terminal device 104 sets a measurement report of the carrier to be measured, where the measurement report includes subcarrier spacing SCS information of the carrier to be measured.
The SCS information of the carrier to be tested may be the SCS value of the synchronization signal block SSB of the carrier.
As a preferred implementation manner, the measurement report may include SSB frequency point information of the carrier to be measured, measurement results of several cells on the frequency point, and SSB subcarrier spacing information of the frequency point.
As a possible implementation manner, in the measurement result of the NR advanced measurement frequency point, SCS indication information and measurement results corresponding to different SCS are added.
The adding of the SCS indication information may specifically include: an SCS information indication field is added, the format of the field can be bitmap, and each bit corresponds to a possible SCS value of SSB. For example, the field may be a bitmap with a size of 4bits, where 4bits correspond to SCS values of 4 possible SSBs: 15kHz,30kHz,120kHz,240kHz. When a certain position of bitmap is 1 (or 0), it can indicate that the measurement result includes the measurement result of the SCS frequency point corresponding to the position. For example, if the positions corresponding to the SCS of 15kHz and 30kHz are set to 1, the measurement result includes the measurement results of the SCS frequency point of 15kHz and the SCS frequency point of 30kHz.
The adding of the measurement results corresponding to different SCS may specifically include: adding a list (which may be referred to as a first list) containing the measurement results corresponding to a plurality of frequency points with the same SSB frequency point and different SCS, wherein the measurement results corresponding to different SCS include the measurement results of a plurality of cells on the SCS frequency point.
For the advanced measurement frequency points with the same SSB frequency point and different SCS of the SSB, the measurement report can be obtained by the following two ways:
(1) And filling the measurement results of the frequency points into the first list according to the ascending/descending order of the SCS values.
(2) The frequency points are sequenced according to the ascending/descending order of the SCS values, the corresponding result of the SCS frequency point with a specific sequencing sequence number (for example, the sequencing is the first or the sequencing is the last) is filled in the cell measurement result of the frequency point in the prior art, and the corresponding results of the other SCS frequency points are filled in the first list in sequence.
For example, if two frequency points with the same SSB frequency point and 15kHz and 30kHz SCS respectively exist in the measurement frequency points in advance, the measurement results of the two frequency points are filled into a first list (for example, the field measresultsrescrislist-r 16) in ascending/descending order according to the SCS value, or the result of the 15kHz frequency point is filled into the cell measurement result of the frequency point in the prior art (for example, the field measresultsreclisidlidl-r 16), and the result of the 30kHz frequency point is filled into the first list. And sets the indications corresponding to SCS of 15kHz and 30kHz in the SCS information indication (e.g., field subanticrier spacing info-r 16) to 1 (or 0).
At S920, the terminal device 104 transmits the measurement report to the network device 102.
At S930, the network device 102 may determine a dual connectivity/carrier aggregation DC/CA configuration for the terminal device 104 from the measurement report.
As an alternative implementation manner, the network device 102 may select a frequency point with a better measurement result in the measurement report as the primary cell SCell or the primary and secondary cell PSCell, and set CA/DC to the terminal device 104.
Specifically, when the measurement report includes frequency points with the same SSB frequency point and different SCS, the network device 102 may select, based on the SCS, a frequency point of a Public Land Mobile Network (PLMN) to which the terminal device 104 belongs as an SCell or PSCell to establish CA/DC for the UE. For example, in the measurement report, the SSB frequency points of frequency point 1 and frequency point 2 are the same, but the SCS of the SSB of frequency point 1 is 15kHz, and the SCS of the SSB of frequency point 2 is 30kHz. The network knows that the frequency point 1 is the frequency point of the PLMN to which the UE belongs and the frequency point 2 is not, so the network can select the frequency point 1 for the UE to establish the CA/DC. For another example, the SSB frequency point with frequency point 1 in the measurement report is f1 and the SCS of the SSB is 15kHz. The network knows that the frequency point SCS of the PLMN to which the UE belongs, whose SSB frequency point is f1, is not 15kHz, that is, the network device 102 can determine that the frequency point 1 in the measurement report is not actually the result of the frequency point of the PLMN to which the terminal device 104 belongs, and then the network device 102 will not misunderstand the measurement report to select the frequency point with the SSB frequency point of f1 for the UE to establish the CA/DC. Therefore, the network can be prevented from selecting wrong frequency points or misunderstanding frequency points of measurement reports to establish CA/DC for the terminal equipment.
It should be understood that, for convenience of description, the above description is given by taking an example of the interaction between the terminal device 104 and the network device 102, in an actual application, the terminal device 104 may interact with the network device 103, or the terminal device 104 may interact with both the network device 102 and the network device 103, and the application is not limited thereto.
It should also be understood that the present application is introduced by taking advance measurement in the prior art as an example, but the technical solution of the present application is not limited to advance measurement, and the technical solution of the present application is also applicable to other types of measurement when one SSB frequency point corresponds to multiple SCS.
According to the technical scheme of the application, the subcarrier spacing SCS information of the carrier to be measured is added in the measurement report, so that for the measurement frequency points with the same SSB frequency point and different subcarrier spacing information of the synchronous signal block, the network equipment can distinguish the measurement results corresponding to different subcarrier spacing information, and the network equipment is favorable for providing reasonable double-connection/carrier aggregation DC/CA configuration for the terminal equipment.
