Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical scheme of the invention can be applied to various communication systems, such as: global System for Mobile communications (GSM), Code Division Multiple Access (CDMA) System, Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term evolution/enhanced Long Term evolution (LTE-a), NR, and the like.

User equipments, which may be Terminal equipments such as Mobile phones (or "cellular" phones) and computers with Terminal equipments, for example, portable, pocket, hand-held, computer-included or vehicle-mounted Mobile devices, may communicate with one or more core networks via a Radio Access Network (RAN), and may exchange languages and/or data with the Radio Access Network.

The network device, which may also be referred to as a Base Station, may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, an evolved Node B (eNB or e-NodeB) in LTE, and a 5G Base Station (gNB), and the embodiments of the present invention are not limited thereto, but for convenience of description, the following embodiments use the gNB as an example for description.

For the RLM described in the above background, in the current NR system, the UE monitors the downlink Radio Link quality of a Primary cell (Pcell) or a Primary Secondary cell (PScell) by measuring X number of Radio Link Monitoring Reference signals (RLM-RS) periodically transmitted and configured on a currently activated Bandwidth Part (BWP) on the network side.

If a physical layer of the UE measures that PDCCH Block Error rates (BLER) corresponding to X RLM-RSs on a currently activated BWP are all higher than a certain BLER threshold, a signal to Interference plus Noise Ratio (SINR) criterion is generally adopted, that is, if all SINRs are lower than a certain SINR threshold, an out-of-sync (OOS) indication is reported to a higher layer. If the high layer continuously receives N310 OOS indications, a timer T310 is started, wherein N310 represents the maximum number of continuous out-of-sync indications received from the bottom layer.

If the physical layer of the UE measures that at least one of PDCCH-BLERs corresponding to X RLM-RSs on the currently activated BWP IS lower than a certain BLER threshold, the SINR criterion IS generally adopted, namely if at least one SINR IS higher than a certain SINR threshold, a synchronization (in-sync, IS) indication IS reported to a high layer. The running of the timer T310 IS stopped if N311 IS indications are received consecutively by the upper layer, where N311 represents the maximum number of consecutive synchronization indications received by the upper part of the bottom layer.

If the timer T310 runs out of time, the UE determines that the Radio Link Failure (RLF) occurs, and then the user plane data transmission between the UE and the network is interrupted.

Wherein, in the case of less than 3GHz, the maximum value of X is 2; between 3GHz-6GHz, X ═ 4; in the case of greater than 6GHz, X ═ 8; the value of N310, the value of N311, and the running time length of the timer T310 may be configured by the network; in the NR system, the RLM-RS may be a Channel-State Information Reference Signal (CSI-RS) or a Synchronization Signal Block (SSB), and two RLM-RSs may be configured to one UE at the same time.

In the BFD process of the existing NR system, the network side configures Y periodically transmitted Beam Failure Detection Reference signals (BFD-RS) for each BWP configured to the UE, and the BFD-RS may be a periodic CSI-RS or an SSB. And the physical layer of the UE measures the BFD-RS and judges whether to report a Beam Failure event (BFI) indication to the high layer or not according to the measurement result.

If the physical layer of the UE measures that all the PDCCH-BLERs corresponding to the BFD-RSs(s) on the BWP activated by the UE of a certain serving cell are higher than a certain BLER threshold, reporting a BFI indication to a high layer, otherwise, not sending any indication to the high layer. The high layer of the UE is provided with a wave beam failure detection Timer (BFD Timer) and a wave beam failure event Counter (BFI Counter), when the high layer of the UE receives a BFI indication reported by a physical layer, the wave beam failure event Timer is started or restarted, the wave beam failure event Counter is accumulated by 1, if the counting number of the wave beam failure event Counter is more than or equal to the maximum number of times configured by a network, the UE judges that the wave beam failure occurs in the current service cell, and the wave beam recovery process is triggered. If the beam failure detection timer runs out of time, the higher layer of the UE will reset the count of the beam failure event counter to 0. Wherein the maximum value of Y is 2.

For the above RLM-RS or BFD-RS, the network may be configured through Radio Resource Control (RRC) signaling. When the network does not configure the RLM-RS or the BFD-RS, the UE may perform RLM or BFD according to the SSB or CSI-RS indicated by the Transmission Configuration indicator state (TCI state) corresponding to the Control Resource Set (core Set) configured on the currently activated BWP.

In addition, for each Discontinuous Reception (DRX) cycle of an idle (idle) state or an RRC Connected (Connected) state of the NR system, the network device first transmits a Wake Up Signal (WUS) to the UE before an active period (On-duration) of DXR, and the UE detects the WUS at a corresponding time. If the UE detects the WUS, the UE starts an active time timer (DRX On-duration timer) in an active period of DRX, monitors a PDCCH, and can perform operations such as CSI reporting and Sounding Reference Signal (SRS) sending; if the UE does not detect the WUS, the UE does not perform the above operation in the active period of DRX, skips the DRX, and continues to sleep, so as to reduce the power consumption of the UE, as shown in fig. 1.

That is, when the network device configures DRX for the UE, the network device may further configure monitoring of the energy-saving PDCCH, and may determine whether a next DRX on-duration needs to perform a sending or receiving operation according to an indication of monitoring the energy-saving PDCCH.

The network device may explicitly inform the UE to perform the above-mentioned receiving or transmitting action in DRX through a power-saving PDCCH (which may also be referred to as WUS PDCCH), or to skip the DRX, i.e. not to perform the above-mentioned receiving or transmitting action. The energy-saving PDCCH may be transmitted through a group common (groupcommon) PDCCH, that is, one Downlink Control Information (DCI) may include an indication of whether a plurality of UEs are awake.

In addition to the above sending and receiving operations, the connected UE may perform corresponding measurement or evaluation every X DRX cycles, specifically, the measurement or evaluation needs to be performed based on the SSB or CSI-RS, while the SSB and CSI-RS signals, the cycle of the energy-saving PDCCH, and the monitoring location are configured independently, and the UE may need to turn on the receiver multiple times to perform measurement and PDCCH monitoring operations, respectively, which increases the power consumption of the UE.

As can be seen from the above, for PDCCH monitoring, the UE performs channel estimation and PDCCH Demodulation using a PDCCH Demodulation Reference Signal (DMRS), and for BFD and RLM, the UE performs radio link quality detection using CSI-RS or SSB. Thus, the UE needs to perform different receiving operations according to different requirements, which is not favorable for power saving of the UE.

Therefore, a new measurement scheme capable of saving power consumption of the terminal device is needed.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present invention provides a measurement method, which is executed by a terminal device, and the method includes the following steps:

step 101: and acquiring configuration information, wherein the configuration information comprises a target control resource set (CORESET) for performing target measurement and a target measurement opportunity corresponding to the target CORESET, and the target measurement comprises at least one of Radio Link Monitoring (RLM) measurement and Beam Failure Detection (BFD) measurement.

Optionally, the configuration information may be obtained from a network device; in the case that the network device configures one or more CORESETs for the terminal device, the configuration information may indicate a target CORESET in which the terminal device is available for measurement, and further give a configuration of a measurement opportunity.

Optionally, for the radio link monitoring RLM measurement or the beam failure detection BFD measurement, the link quality may be determined based on a measurement evaluation of a corresponding reference signal, for example, by determining whether the BLER of the PDCCH is lower than a corresponding threshold a or higher than a corresponding threshold B, so as to determine the link quality.

Step 103: and performing target measurement according to a demodulation reference signal (DMRS) of a Physical Downlink Control Channel (PDCCH) in the target measurement opportunity.

Optionally, in the measurement method according to the embodiment of the present invention, the DMRS of the PDCCH in the target CORESET is a wideband DMRS.

It can be understood that the transmission of the DMRS of the PDCCH is performed in a manner that the DMRS is mapped in all Resource Element Groups (REGs) in the target CORESET.

Optionally, in the measurement method according to the embodiment of the present invention, the DMRS of the PDCCH in the target measurement occasion is a wideband DMRS.

It can be understood that, the DMRS of the PDCCH is transmitted in a manner that only the DMRSs are mapped in all REGs corresponding to the target measurement occasion in the target CORESET, that is, only the DMRSs of the PDCCH in the target measurement occasion in the target CORESET are wideband DMRSs, so as to ensure flexibility in transmitting the PDCCH. That is to say, when monitoring the PDCCH at the target measurement occasion, the terminal device does not need to determine whether the DMRS therein is the wideband DMRS according to the indication of the network device, and when monitoring the PDCCH at the remaining measurement occasions except the target measurement occasion in the target CORESET, the terminal device still needs to determine whether the DMRS therein is the wideband DMRS according to the indication of the network device.

Optionally, in the measurement method according to the embodiment of the present invention, different configurations may be given for the target measurement occasion indicated by the configuration information in different implementations.

In a specific embodiment, the target measurement occasion is a PDCCH monitoring occasion in a target search space set SS set associated with a target CORESET.

It can be understood that the target measurement occasion may be given by the network device based on the existing PDCCH monitoring occasion configuration, that is, the PDCCH monitoring occasion in the target Search Space set (SS set) associated with the target CORESET, that is, the configuration information may further include a Search Space for performing the target measurement. Further preferably, the target measurement occasions included in the configuration information may be partial listening occasions in the target SS set.

Further optionally, a period corresponding to the target measurement opportunity is greater than a period corresponding to the target SS set.

It is to be understood that, in order to make the terminal device not to perform frequent measurement, the period of the target measurement occasion is indicated by the configuration information to be longer than the period (such as 5ms) corresponding to its associated target SS set, i.e. the period of the target measurement occasion included in the configuration information may be a relatively long time duration, such as 20ms or 80 ms.

Further optionally, the target measurement occasion is a PDCCH monitoring occasion in at least one time slot within the duration indicated by the target SS set.

It is understood that a partial listening opportunity in at least one time slot within a duration is indicated by the target SS set as the target measurement opportunity to make the corresponding measurement.

In another specific embodiment, the above target measurement occasion is independent of the PDCCH monitoring occasion in the target SS set associated with the target CORESET.

It can be appreciated that the target measurement occasion can be configured for the network device independently of the existing PDCCH monitoring occasion for the terminal device.

Optionally, in any of the above embodiments, the target SS set may be a common search space set CSS set.

It is understood that the DMRS sequence for the PDCCH in CSS set may be generated independently of the terminal device specific scrambling id (identifier) for all terminal devices to measure.

Specifically, in the CSS set, since a large number of PDCCHs corresponding to a broadcast Physical Downlink Shared Channel (PDSCH) in a cell are periodically transmitted, generally, there are many PDCCHs multiplexed at a PDCCH monitoring time (monitongcasino), and a network device may configure a CORESET that transmits the broadcast PDCCH and the PDCCH in a group common (groupcommon) as a wideband dmrs, that is, each REG in the CORESET has a PDCCHDMRS. When the terminal equipment uses the PDCCHDMRS for measurement, better precision can be obtained.

Further optionally, in case the target SS set is a CSS set, the target SS set comprises one of:

SS set of PDCCH for monitoring System Information Block (SIB 1);

SS set of PDCCH for monitoring system information SI message;

SS set of PDCCH for monitoring Paging message;

an SS set of the PDCCH for monitoring the wake-up signal WUS;

SSset for PDCCH of listening slot format (slotted).

Optionally, in any of the above embodiments, the target SS set may be a terminal device specific search space set USS set.

It will be appreciated that the generation of DMRS sequences for the PDCCH in USS set may be associated with a terminal device specific scrambling ID for measurements by a particular terminal device.

Optionally, in the measurement method according to the embodiment of the present invention, in the case that the terminal device receives DRX discontinuously, thestep 103 may be specifically executed as follows:

and when the target measurement occasion is in the DRX period, performing target measurement according to the DMRS of the PDCCH in the target measurement occasion.

It is understood that the DMRS of the PDCCH in the monitoring occasion corresponding to the SS set of the PDCCH for monitoring the wake-up signal WUS (i.e., monitoring the energy-saving PDCCH) or a part of the monitoring occasions therein may be used as the measurement resource based on the configuration information. Therefore, the terminal equipment can monitor the WUS and complete the measurement operation at the same time, so that the power consumption of the terminal equipment is saved.

Further, considering that the terminal device monitors outside the active period (i.e., the sleep period) of the DRX (i.e., the energy-saving PDCCH) when monitoring the WUS, and that the CORESET used for monitoring the PDCCH inside and outside the active period of the DRX is the same, optionally, the DMRS of the PDCCH may be preset as the wideband DMRS when monitoring the WUS, and in other cases outside monitoring the WUS, the terminal device needs to determine whether the DMRS of the PDCCH is the wideband DMRS according to the configuration of the network device on the DMRS on the CORESET.

Optionally, in the measurement method according to the embodiment of the present invention, the target measurement may further include at least one of:

(1) radio resource management RRM measurements.

Specifically, the RRM measurement may be used to measure at least one of measurement quantities such as RSRP, Reference Signal Received Quality (RSRQ), and Received Signal Strength Indication (RSSI).

(2) Channel state information, CSI, measurements.

Specifically, the CSI measurement may be used to measure at least one of measurement quantities such as a physical layer L1-RSRP, a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), and a Rank Indicator (RI).

Further, based on the difference of the target measurement, theabove step 103 may be executed as different content to ensure the applicability of the measurement method of the embodiment of the present invention.

Optionally, in the case that the target measurement is an RLM measurement, thestep 103 may be specifically executed as follows:

and under the condition that the T310 timer is not started, performing RLM measurement according to the DMRS of the PDCCH in the target measurement opportunity.

It can be understood that, when performing RLM measurement according to the DMRS of the PDCCH in the target measurement occasion, it needs to be performed without starting the T310 timer by the terminal device. That is, the RLM measurement may be performed using the DMRS of the PDCCH in the target measurement occasion as a measurement resource before the T310 timer is started.

Further, if the terminal device starts the T310 timer once, the terminal device may use the SSB or CSI-RS configured by the network device to perform RLM measurement; alternatively, the terminal device may perform RLM measurement using an RS indicated by a Transmission Configuration Indicator (TCI) status (state) of activation of CORESET.

Optionally, in the case that the target measurement is an RRM measurement, thestep 103 may be specifically executed as follows:

and under the condition that the result of RRM measurement based on the synchronization signal block SSB or the channel state information reference signal CSI-RS is higher than a set threshold, RRM measurement is carried out according to the DMRS of the PDCCH in the target measurement opportunity.

It can be understood that when RRM measurement is performed according to the DMRS of the PDCCH in the target measurement occasion, a certain condition needs to be satisfied, that is, a result (RSRP or RSRQ) of RRM measurement performed based on the synchronization signal block SSB or the channel state information reference signal CSI-RS is higher than a set threshold.

Further optionally, in the measurement method according to the embodiment of the present invention, if a result (RSRP or RSRQ) of performing RRM measurement according to the DMRS of the PDCCH in the target measurement occasion is lower than the set threshold, the terminal device may perform RRM measurement based on the SSB or the CSI-RS according to the configuration of the network device. That is to say, the measurement method according to the embodiment of the present invention may further include the following steps:

and under the condition that the result of RRM measurement based on the DMRS of the PDCCH in the target measurement occasion is lower than a set threshold, RRM measurement is carried out according to the SSB or the CSI-RS.

Referring to fig. 3, an embodiment of the present invention provides a measurement method, executed by a network device, where the method includes the following steps:

step 201: generating configuration information, wherein the configuration information comprises a target control resource set (CORESET) for performing target measurement and a target measurement opportunity corresponding to the target CORESET, and the target measurement comprises at least one of Radio Link Monitoring (RLM) measurement and Beam Failure Detection (BFD) measurement.

Optionally, in a case that one or more CORESETs are configured for the terminal device, the configuration information may include a target CORESET that can be used for the terminal device to measure, and further may further provide a configuration of a measurement opportunity.

Step 203: and sending the configuration information to the terminal equipment, wherein the configuration information is used for the terminal equipment to perform target measurement according to a demodulation reference signal (DMRS) of a Physical Downlink Control Channel (PDCCH) in the target measurement opportunity.

In the embodiment of the present invention, by configuring configuration information for performing corresponding measurement for a terminal device, the terminal device may determine, based on the received configuration information, a target CORESET for performing target measurement and a target measurement occasion occase in the target CORESET, and further may enable the terminal device to perform corresponding measurement operation of at least one of RLM measurement and BFD measurement using a DMRS of a PDCCH in the target measurement occasion as a measurement resource. Therefore, the terminal equipment is configured with the measurement opportunity for measurement, and the DMRS of the PDCCH in the configured measurement opportunity is used for carrying out corresponding measurement operation, so that the terminal equipment does not need to carry out different receiving operations according to different requirements, the purpose of saving the power consumption of the terminal equipment can be achieved, and meanwhile, the expense of sending measurement resources by a network side can be reduced.

It can be understood that the DMRS is transmitted through the PDCCH by configuring a manner in which the DMRS is mapped to all resource element groups in the target CORESET.

It can be understood that, the DMRSs are transmitted in the PDCCH by configuring a manner of mapping the DMRSs only in all REGs corresponding to the target measurement occasions in the target CORESET, that is, only the DMRSs of the PDCCH in the target measurement occasions in the target CORESET are wideband DMRSs, so as to ensure flexibility of transmitting the PDCCH. That is to say, when monitoring the PDCCH at the target measurement occasion, the terminal device does not need to determine whether the DMRS therein is the wideband DMRS according to the indication of the network device, and when monitoring the PDCCH at the remaining measurement occasions except the target measurement occasion in the target CORESET, the terminal device still needs to determine whether the DMRS therein is the wideband DMRS according to the indication of the network device.

Optionally, in the measurement method according to the embodiment of the present invention, the target measurement timing included in the configuration information may be configured to be different in different implementations.

It can be understood that the target measurement occasion is given based on the existing PDCCH monitoring occasion configuration, i.e. configured as a PDCCH monitoring occasion in the target search space set SS set associated with the target CORESET, that is, the search space used by the terminal device for performing the target measurement may be further indicated based on the configuration information. Further preferably, the configuration information may indicate a part of the listening occasions in the target SS set as the target measurement occasions.

It is understood that, in order to make the terminal device not to perform frequent measurement, the configuration information may be configured to indicate that the period of the target measurement occasion is longer than the period (such as 5ms) corresponding to the target SS set, i.e. the configuration information may indicate that the period of the target measurement occasion is a relatively long time, such as 20ms or 80 ms.

It is to be understood that the partial listening opportunity in at least one time slot indicated by the target SS set for a duration is configured as the target measurement opportunity to perform the corresponding measurement.

It can be appreciated that the terminal device is separately configured with a target measurement occasion that is independent of the existing PDCCH monitoring occasion.

It is to be understood that the DMRS sequence of the PDCCH in CSS set may be generated independently of the terminal device specific scrambling ID for all terminal devices to measure.

Specifically, in the CSS set, since a large number of PDCCHs corresponding to the PDSCH are periodically transmitted in a cell, there are usually more PDCCHs multiplexed on PDCCH monitoring occasions, and the network device may configure the CORESET that transmits the PDCCH, the groupcommon PDCCH, and the widebanddmrss, that is, each REG in the CORESET has a PDCCHDMRS. When the terminal equipment uses the PDCCHDMRS for measurement, better precision can be obtained.

SS set for monitoring PDCCH of system information block SIB 1;

SS set of PDCCH for monitoring system information SI message;

SS set of PDCCH for monitoring Paging message;

an SS set of the PDCCH for monitoring the wake-up signal WUS;

SS set for monitoring the PDCCH in slot format.

Optionally, in the measurement method according to the embodiment of the present invention, in a case that the terminal device is configured with the discontinuous reception DRX, the configuration information is used for the terminal device to perform target measurement according to the DMRS of the PDCCH in the target measurement occasion when the terminal device is in the DRX cycle.

It is understood that the monitoring occasion corresponding to the SS set of the PDCCH for monitoring the wake-up signal WUS (i.e., monitoring the energy-saving PDCCH) or the DMRS of the PDCCH in a partial monitoring occasion thereof may be indicated as a measurement resource based on the configuration information. Therefore, the terminal equipment can monitor the WUS and complete the measurement operation at the same time, so that the power consumption of the terminal equipment is saved.

Further, considering that the terminal device monitors outside the active period (i.e., the sleep period) of the DRX (i.e., the energy-saving PDCCH) when monitoring the WUS, and that the CORESET used for monitoring the PDCCH inside and outside the active period of the DRX is the same, optionally, the DMRS of the PDCCH may be preset as the wideband DMRS when the terminal device monitors the WUS, and in other cases outside the monitoring of the WUS, the terminal device is instructed to determine whether the DMRS of the PDCCH is the wideband DMRS according to the configuration of the network device on the DMRS on the CORESET.

(1) radio resource management RRM measurements.

Specifically, the measurement of at least one of measurement quantities such as RSRP, RSRQ, and RSSI may be performed by RRM measurement.

(2) Channel state information, CSI, measurements.

Specifically, the measurement of at least one of the measurement quantities of the physical layer L1-RSRP, CQI, PMI, RI, and the like can be realized by CSI measurement.

Further, based on the difference of the target measurement, the measurement resources indicated by the configuration information may be different, and then the measurement operation performed by the terminal device based on the corresponding measurement resources is also different.

Optionally, when the target measurement is RLM measurement, the configuration information is used for the terminal device to perform RLM measurement according to the DMRS of the PDCCH in the target measurement occasion when the T310 timer is not started.

It can be understood that, when the terminal device is instructed to perform the RLM measurement according to the DMRS of the PDCCH in the target measurement occasion, the RLM measurement needs to be performed without starting the T310 timer by the terminal device. That is, before the T310 timer starts, the terminal device may be instructed to perform RLM measurement using the DMRS of the PDCCH in the target measurement occasion as a measurement resource.

Further, if the terminal device starts the T310 timer once, it indicates that the terminal device can use the SSB or CSI-RS configured by the network device to perform RLM measurement; alternatively, the terminal device may perform RLM measurement using an RS indicated by a Transmission Configuration Indicator (TCI) status (state) of activation of CORESET.

Optionally, when the target measurement is RRM measurement, the configuration information is used for the terminal device to perform RRM measurement according to a DMRS of a PDCCH in the target measurement opportunity when a result of RRM measurement performed based on a synchronization signal block SSB or a channel state information reference signal CSI-RS is higher than a set threshold.

It can be understood that when the terminal device is instructed to perform RRM measurement according to the DMRS of the PDCCH in the target measurement occasion, a certain condition needs to be satisfied, that is, a result (RSRP or RSRQ) of RRM measurement performed based on the synchronization signal block SSB or the channel state information reference signal CSI-RS is higher than a set threshold. That is, only when the result (RSRP or RSRQ) of RRM measurement based on the synchronization signal block SSB or the channel state information reference signal CSI-RS is higher than the set threshold, the terminal device may be instructed to perform RRM measurement using the DMRS of the PDCCH in the target measurement occasion as a measurement resource.

Further optionally, in the measurement method according to the embodiment of the present invention, if a result (RSRP or RSRQ) of RRM measurement performed by the terminal device according to the DMRS of the PDCCH in the target measurement occasion is lower than the set threshold, the terminal device may be instructed to perform RRM measurement based on the SSB or the CSI-RS according to configuration of the network device.

That is to say, in the measurement method according to the embodiment of the present invention, when the target measurement is RRM measurement, the configuration information is further used for the terminal device to perform RRM measurement according to the SSB or the CSI-RS when a result of RRM measurement based on the DMRS of the PDCCH in the target measurement occasion is lower than a set threshold.
