Technical Field

The present disclosure relates to the field of wireless communications technologies, but not limited to the field of wireless communications technologies, and in particular, to a method and an apparatus for scheduling measurement gaps, a communication device, and a storage medium.

Background

A Measurement Gap (Measurement Gap) may be used to measure a reference signal of a neighbor cell. The reference signals include, but are not limited to: a Synchronization Signal Block (SSB) or a Channel State Indication Reference Signal (CSI-RS). In a New Radio (NR) system, when a User Equipment (UE) performs mobility measurement, if a reference signal (SSB or CSI-RS) of a neighbor cell to be measured is not in a frequency domain of a currently active Bandwidth Part (BWP), the UE needs a measurement gap to complete the measurement.

The research finds that: the rate of BWP switched by the UE is higher than the rate of scheduling measurement gaps by the base station; the handover of BWP is more dynamic than the scheduling of measurement gaps by the base station.

Alternatively, the UE11 may be a roadside device, such as a street lamp, a signal lamp, or other roadside device with wireless communication capability.

The base station 12 may be a network side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication (4G) system, which is also called a Long Term Evolution (LTE) system; alternatively, the wireless communication system can be a 5G system, which is also called a New Radio (NR) system or a 5G NR system.

Several base stations 12 are connected to a network management device 13, respectively. The network Management device 13 may be a Core network device in a wireless communication system, for example, the network Management device 13 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the Network management device may also be other core Network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), a Home Subscriber Server (HSS), or the like. The implementation form of the network management device 13 is not limited in the embodiment of the present disclosure.

In one embodiment, the measurement gap is configured by means of RRC configuration/reconfiguration signaling, and the BWP handover may be performed by means of RRC configuration/reconfiguration, DCI, or timer (timer). Therefore, when BWP handover is switched by means of DCI, BWP handover is more dynamic or faster than measurement gap, and it is difficult for the network to configure or cancel the configured measurement gap according to BWP handover, so in this case, the network may always assume that the measurement gap is used for mobility measurement, which will cause loss of throughput to the network and the terminal. Referring to fig. 2, at time T0, the active BWP of the UE is BWP1, the UE does not need the measurement gap when measuring neighbor cell 1, and needs the measurement gap when measuring neighbor cells 2 and 3, and when the UE active BWP switches to BWP2, the UE needs the measurement gap when measuring neighbor cells 1 and 2, and does not need the measurement gap when measuring neighbor cell 3.

Active BWP here is understood to be: the BWP the UE is currently operating in.

As shown in fig. 3, an embodiment of the present disclosure provides a method for scheduling measurement gaps, where the method is applied to a base station, and includes:

s110: and scheduling the measurement gap through Downlink Control Information (DCI).

Here, the measurement gap is scheduled by DCI, that is, a scheduling instruction of the measurement gap is issued by DCI. The transmission rate of DCI is faster than RRC signaling. The measurement gap is scheduled by using the DCI, so that the switching of the BWP and the switching scheduling of the measurement gap are indicated by using the DCI, and the phenomenon that the switching scheduling of the measurement gap is not matched with the BWP switching rate because the measurement gap is scheduled by using RRC signaling for switching by using the DCI is reduced.

In one embodiment, the S110 may include:

and issuing DCI for scheduling the measurement gap according to the working BWP switched by the UE or the working BWP to be switched in.

For example, the working BWP of the UE is switched from BWPm to BWPn, where n and m are the numbers of BWP available in the serving cell; and m and n are natural numbers with different values. The UE's active BWP may become active BWP again.

At this time, according to the BWPn and the working frequency points of the adjacent cells of the service cell, the measurement gaps capable of measuring at least part or all of the adjacent cells are determined, and the DCI is issued according to the determined measurement gaps.

Exemplarily, after BWP handover of the UE, the measurement gaps of the frequency points between the UE and the neighboring cell 1, the neighboring cell 2, and/or the neighboring cell 3 are: a measurement gap 1, a measurement gap 2 and a measurement gap 3; then measurement gap 1, measurement gap 2 and measurement gap 3 may be activated by DCI issue at this time; the activation instruction of (1). If the DCI only carries the activation instruction and the measurement gap indicated by the activation instruction is not detected in some scenarios, the DCI is deactivated by default.

For example, before BWP handover of the UE, the activated measurement gap 4 may also carry an activation instruction for activating measurement gap 1 and measurement gap 2 and a deactivation instruction for deactivating measurement gap 4 through DCI. As such, DCI not only specifies activated measurement gaps but also deactivated measurement gaps; while currently DCI does not explicitly deactivate measurement gap 3, it may be considered to maintain the activation of measurement gap 3.

In short, the activation instruction and/or the deactivation instruction carried in the DCI may be one of scheduling instructions for scheduling a measurement gap.

Of course, the above is only an example of the DCI scheduling measurement gap, and the specific implementation is not limited to the above example.

As shown in fig. 4A and/or 4B, embodiments of the present disclosure provide a measurement gap configuration method, which may include:

s100: and sending the configuration information of the measurement gap through Radio Resource Control (RRC) signaling.

In the embodiment of the present disclosure, the measurement gap configuration method may be used alone, or may be used in combination with the measurement gap scheduling method shown in fig. 3. That is, in an implementation scenario, before the measurement gap is scheduled through DCI, the measurement gap configuration may be performed through RRC signaling, and the measurement gap for DCI scheduling is: one or more of the RRC signaling configured measurement gaps.

The RRC signaling herein includes, but is not limited to, the aforementioned RRC configuration signaling and/or RRC reconfiguration signaling. The RRC signaling carries configuration information of the measurement gap.

The configuration information may indicate at least one of:

a neighbor cell of a reference signal to be measured;

measuring time domain position information of the gap;

measuring the duration of the gap;

measuring the distribution density of the gap in the time domain, and the like.

In the embodiment of the present disclosure, the RRC signaling carrying the DCI with the measurement gap may be sent before the DCI with the measurement gap is sent down.

In one embodiment, the configuration information includes:

the configuration indication of the measurement gap comprises a measurement index, a measurement object identifier corresponding to the measurement index and a measurement gap corresponding to both the measurement index and the measurement object identifier.

For example, the configuration information may include: and the mapping table is formed by one or more mapping relations.

One of the mapping relationships comprises: a configuration index, measurement object identifiers and configuration indications of measurement gaps.

Table 1 is an example of the configuration information:

TABLE 1

In one embodiment, any one of the elements of Table 1 may be used alone or in combination with one or more other elements of the table.

In one embodiment, the number of the measurement indexes is consistent with the maximum number of measurement object identifiers of the DCI support configuration.

It is to be understood that the DCI may have an indication field for scheduling the measurement gap. The number of bits contained in the indication field determines the maximum number of measurement object identifiers indicated by the DCI support. Illustratively, the indication field includes: 6 bits, the indication field has 64 bit values, and the maximum can indicate 64 measurement object identifications. In the embodiment of the present disclosure, the number of the measurement objects may be equal to the maximum number of the measurement objects indicated by the DCI support, for example, 64. I.e. one said DCI may make 64 different schedules for the measurement interval.

In one embodiment, one of the measurement indices corresponds to at least one measurement object identification; the measurement index and the measurement object identifier corresponding to the measurement index correspond to one of the configuration indications.

A measurement index may correspond to a measurement object identifier alone or a group of measurement object identifiers. The set of measurement object identifications may include: one or more measurement object identifications. For example, if one neighboring cell corresponds to one measurement object, the set of measurement identifiers may be: and the bandwidth identification of the bandwidth of the SSB corresponding to all or part of the neighbor cells of the serving cell where the UE is located.

In one embodiment, a measurement index and one or more measurement object identifiers corresponding to the measurement index form a combination, which may be referred to as an identifier combination; one such combination of identifications may correspond to one configuration indication.

One of the configuration indexes may be formed of one or more bits, and when the corresponding measurement index is carried by the DCI, the configuration indicates whether the indicated measurement object is configured with a measurement gap or not by the indicated measurement object identifier indicating win.

In one embodiment, the configuration indication comprises at least one of:

a first indication indicating that a measurement gap corresponding to the measurement object identifier is configured;

and a second indication indicating that no measurement gap corresponding to the measurement object identifier is configured.

In table 1, the configuration of the index flag #0 and the measurement object flag #0 is indicated as 0; and the configuration of the index flag #1 and the measurement object flag #0 is indicated as 1. If the configuration indication is '0' indicating that no measurement gap is configured, the configuration indication is '1' indicating that a measurement gap is configured; or; if the configuration indication is "1" indicating that no measurement gap is configured, the configuration indication is "0" indicating that a measurement gap is configured.

For example, a serving cell in which the UE is located has N neighbor cells; the UE has N neighbor cells to be measured. When the UE operates on a BWP of the serving cell, some of the neighbor cells may need to be measured with reference signals, and some other neighbor cells may or may not be measured. Therefore, the configuration indications corresponding to the multiple measurement object identifiers corresponding to one index identifier have values of "0" and "1".

In one embodiment, the DCI carries the valid measurement index; wherein the measurement gap corresponding to the measurement index carried by the DCI is activated.

For example, the measurement index carried by the DCI takes effect, and the measurement gap indicated by the first indication corresponding to the effective measurement index is activated. If the measurement index carried by the DCI is different from the currently effective measurement index of the UE, the switching of the measurement gap is realized.

In an embodiment, the scheduling, by means of the downlink control information DCI, the measurement gap includes:

scheduling the measurement gap through DCI carrying a switching instruction, wherein the switching instruction is as follows: instructing the UE to switch the operating bandwidth part BWP.

In the embodiment of the present disclosure, the indication information for scheduling the measurement gap and the handover instruction for indicating the UE to perform BWP handover are carried in the same DCI, so that the UE receives the handover instruction for BWP handover and the indication information for scheduling the measurement gap at the same time, and obviously, the base station side realizes synchronization of BWP handover and measurement gap scheduling.

In one embodiment, the format of the DCI scheduling the measurement gap is: 1-1. The DCI with format1-1 is DCI format 1-1.

Of course, in another embodiment, the format of the DCI scheduling the measurement gap may be other formats, for example, other formats such as 1-2, 2-1, 2-2, etc.

As shown in fig. 5, an embodiment of the present disclosure provides a method for scheduling measurement gaps, where the method, applied to a user equipment UE, includes:

s210: receiving DCI scheduling a measurement gap.

The measurement gap scheduling method provided by the embodiment of the disclosure is applied to UE.

The UE may be various types of communication terminals, including but not limited to: the system comprises a mobile phone, a tablet personal computer, vehicle-mounted equipment, intelligent household equipment, intelligent office equipment, intelligent teaching equipment and/or road equipment and the like.

The smart home devices include but are not limited to: a sweeping robot and/or an intelligent curtain, etc. The intelligent office equipment includes but is not limited to: intelligent printers and/or intelligent door locks, etc.

The intelligent teaching device includes but is not limited to: a projection device in a classroom and/or a monitoring device in a classroom.

In the embodiment of the present disclosure, the measurement of the measurement gap is scheduled by DCI with a fast sending rate, so that a phenomenon that the measurement gap is not scheduled and switched in time when the UE switches over different BWPs can be reduced.

In one embodiment, as shown in fig. 6A and/or fig. 6B, a configuration method for measuring a gap according to an embodiment of the present disclosure may include:

s200: and receiving RRC signaling carrying the configuration information of the measurement gap.

In the embodiment of the present disclosure, the configuration information for issuing the measurement gap is configured by RRC signaling.

The method for configuring the measurement gap may be used independently of the method for scheduling the measurement gap, or may be used in combination with the method for scheduling the measurement gap, that is, in an embodiment, the measurement gap is configured through RRC signaling, and the measurement gap is scheduled through DCI, where the measurement gap scheduled by DCI is the measurement gap configured through RRC signaling.

In one embodiment, the RRC signaling may be any signaling transmitted by the RRC layer, including but not limited to: RRC configuration signaling and/or RRC reconfiguration signaling.

In one embodiment, the configuration of the measurement gap by the configuration information may be: each measurement gap is individually configured with a gap index, and the DCI may carry the gap index of the activated and/or deactivated measurement gap. And the activated measurement gap or gaps can be used for measuring the SSBs of all the neighbor cells.

In one embodiment, the configuration information includes:

In an embodiment of the present disclosure, the configuration information includes: measurement index, measurement object identification, configuration indication of measurement gap. At this time, one measurement index may correspond to a configuration indication of a set of measurement gaps. The measurement object identifier may be an identifier of a frequency point of a neighboring cell.

For example, if the serving cell where the UE is currently located includes N neighboring cells, in the embodiment of the present disclosure, one measurement index may correspond to N measurement object identifiers and N configuration indications at the same time.

Thus, the DCI can activate and/or deactivate the measurement gap of the N cells by carrying the measurement index, and has the characteristic of low signaling overhead.

It is to be understood that the DCI may have an indication field for scheduling the measurement gap. The number of bits contained in the indication field determines the maximum number of measurement object identifiers indicated by the DCI support. Illustratively, the indication field includes: 6 bits, the indication field has 64 bit values, and the maximum can indicate 64 measurement object identifications. In the embodiment of the present disclosure, the number of the measurement objects may be equal to the maximum number of the measurement objects indicated by the DCI support, for example, 64 described above. I.e. one said DCI may be scheduled 64 different times for a measurement interval.

In one embodiment, one said measurement index corresponds to at least one measurement object identification; the measurement index and the measurement object identifier corresponding to the measurement index correspond to one of the configuration indications.

In one embodiment, the configuration indication comprises at least one of:

a first instruction indicating that a measurement gap corresponding to the measurement target identifier is configured;

In the specific configuration of the measurement configuration provided in the embodiment of the present disclosure, reference may be made to the foregoing embodiment, for example, table 1 in the foregoing embodiment.

The activated measurement gap, i.e. the measurement gap that needs to be put into use, i.e. the measurement gap scheduled by the DCI. If a certain measurement gap is scheduled by DCI, the UE will measure the SSB of the corresponding neighboring cell in the scheduled (or activated) measurement gap.

In one embodiment, the S210 may include:

receiving DCI which schedules the measurement gap and carries a switching instruction, wherein the switching instruction is as follows: instructing the UE to switch the operating bandwidth part BWP.

In the embodiment of the present disclosure, the switching instruction and the scheduling instruction of the measurement gap are carried in the same DCI, so that synchronization of BWP switching and scheduling of the measurement gap is easily achieved, and a phenomenon that BWP switching and measurement gap switching are different from each other is reduced.

In one embodiment, the DCI scheduling the measurement gap has a format of: 1-1.

In combination with any of the above embodiments, a method for scheduling a measurement gap is provided, which may specifically be as follows:

the measurement gap (gap) is configured by RRC configuration/reconfiguration to complete neighbor cell measurement, and the BWP handover may be performed by RRC configuration/reconfiguration, DCI, or a timer. In the related art, if BWP is dynamically changed, the network always assumes a measurement gap for mobility measurement

When BWP handover is switched by means of DCI, BWP handover is more dynamic or faster than measurement gap, and it is difficult for the network to configure or cancel the configured measurement gap according to BWP handover, so in this case, the network may always assume that the measurement gap is used for mobility measurement, which will cause loss of throughput to the network and the terminal.

The embodiment of the disclosure provides a scheduling method and a system for rapidly configuring a measurement gap, wherein when BWP is dynamically switched, measurement gap configuration can be dynamically activated or deactivated according to a frequency domain relationship between a currently activated BWP and a reference signal of a neighboring cell, and throughput of a network and a terminal can be effectively improved.

Illustratively, the method for activating/deactivating the measurement gap configuration provided by the embodiment of the present disclosure may include:

step 1: the network configures the mobility measurement for the UE through measConfig signaling in an RRC reconfiguration message (RRCReconfiguration).

Step 2: introducing an indication message for activating and deactivating measurement gap configuration into the DCI Format 1_1, where the bit number of the indication message is consistent with the supported maximum configurable number of measurement objects (maxNrofObjectId), for example, if the maxNrofObjectId value is 64, the bit number of the indication is 6 bits, "000000" represents the indication message index #0, and so on, "111111" represents the indication message index # 63;

and 3, step 3: a correspondence table indicating MeasObjectId corresponding to measurement object (measurementmobjected) to which the message Index # i is directed is introduced as shown in the following table. Wherein "0" indicates that the UE does not require a measurement gap when measuring the MeasObjectId # j measurement object, and "1" indicates that the UE requires a measurement gap when measuring the MeasObjectId # j measurement object;

TABLE 2

And 4, step 4: the UE receives the DCI Format 1_1(Format 1_1) command, and by parsing the information in the DCI, the UE may obtain a BWP update indication to complete the BWP handover procedure.

In one embodiment, any one of the elements of table 2 may be used alone or in combination with one or more other elements of the table.

The UE obtains the indication information Index #1 for activating/deactivating measurement gap configuration, and by querying the mapping table, it may be determined whether the measurement object identifier MeasObjectId # j corresponding to Index # i needs a measurement gap.

If no measurement gap is needed, the network may schedule the UE during its measurement of MeasObjectId # j.

If a measurement gap is needed, the network cannot schedule the UE during its measurement of MeasObjectId # j.
